A preferred class of embodiments is: and a second sealing ring (26) is arranged at the output port of the connector to prevent oil leakage.

The invention has at least the following advantages:

when the pressurizing spring 19 is pressed by the pressurizing operation of the pressurizing handle, and the sleeve protrusion 40 is relatively moved backward relative to the body 11 by the pressurizing handle, the mouth-opening trigger 23 is activated during the backward movement, so that the biting teeth 25 of the holder 24 are opened, which is more advantageous for smooth insertion of the nipple 50 into the connector 10, and is very advantageous for the user. In addition, the occlusion teeth 25 of the clamping piece are matched with the shape design of the oil nozzle, so that the clamping piece 24 is in surface contact with the oil nozzle, and the oil nozzle has better clamping characteristics.

Therefore, compared with the prior art, the technical scheme disclosed by the invention does not need a specially arranged tapered sleeve, the bent part at the rear end of the clamping piece does not extend inwards to extend into the retaining groove on the attachment body, but deviates from the attachment body and tilts outwards to realize the technical effect of opening the mouth, the problem of stable occlusion of the grease gun connector is solved by unique other technical means (combination), and the technical effect which cannot be realized by the prior art and is required by the practical use is obtained.

[ detailed description ] embodiments

The description mode declares: the embodiments described below are not intended to be merely descriptions of one particular embodiment, but rather are intended to be selective descriptions of potential embodiments having certain features, some of which are not necessarily present. Specific to a particular embodiment, it is a combination of certain features that follows, provided that such combination is not logically contradictory, or meaningless. The appearance of "may/may" anywhere in the invention (may, may be, meaning selected unless the context dictates otherwise), is a description of a preferred embodiment and may be a potential alternative. When the terms of approximate description (if any) such as "approximately", "near", and the like appear at any position of the invention, the intended meaning is not to require that the data obtained after the strict actual parameter measurement strictly conforms to the general mathematical definition, because there is no physical entity completely conforming to the mathematical definition, and the words do not obscure the words and ambiguity, thereby causing ambiguity. In infringement determination procedures, the specific meanings of technical terms/words appearing in the claims are to be interpreted as "broadest reasonable interpretation" of the scope of the claims in a comprehensive examination of the context of the invention, taking the specification as a technical dictionary; in the process of ineffectiveness and the like, the claims should be interpreted reasonably best by the applicant/patentee under the "presumption of patentability principle" to thereby encourage and protect the spirit of the invention in practice of patent laws.

The present invention defines the left side in fig. 1 as the rear/back side (the side near the user hand/connector oil inlet, the direction far from the glib/connector outlet), and the right side as the front/front side (the side near the glib/connector outlet, the direction far from the user hand/connector oil inlet). Those skilled in the art will appreciate that these directional descriptions are merely for ease of understanding/distinction and are not meant to be a narrow limitation on the embodiments.

Referring to fig. 1, a grease gun (not shown in the present invention) delivers pressurized grease to the connector 10 through a delivery tube, which enters the connector 10 through an oil inlet/grease inlet 15 of the connector. Grease is injected into the nipple 50 through the rear side of the attachment channel/third channel 30 of the clip attachment 22 (also known in the art as a sandwich core) and the output end/port of the connector 10.

In certain embodiments, the connector 10 includes a body 11 of the connector 10. A body 11, which may be a solid device having an internal hollow channel (15, 16, 20) for transporting grease, and which may be made of one or a combination of metals (iron, steel, manganese, boron, copper, aluminum, titanium, alloys, etc.), plastics, etc.; it may be integrally formed or a combination of multiple parts/segments.

In certain embodiments, the connector 10 further includes a ferrule 12. The sleeve 12 is movable backward via a first operation (user pressure or pressure removal) applied to a pressurizing handle (not shown in the present invention), and the sleeve 12 is movable forward to return or substantially return to a default state (here, a normal state, i.e., a state in which a user does not apply an operation) when a second operation (user pressure or pressure removal) is applied to the pressurizing handle.

The sleeve 12 is provided with a sleeve projection 40 which follows the movement of the sleeve. For location, the sleeve projection 40 may be located at the forwardmost end of the sleeve or may be located somewhere in the middle of the interior of the sleeve; for assembly, the sleeve projection 40 may be integrally formed with the sleeve or may be mounted on the sleeve 12; the material may be the same as or different from that of the sleeve 12. The sleeve projection 40 may be formed as a single projection ring as a whole or may be a plurality of discrete projection segments. In particular, the sleeve protrusion 40 and the sleeve 12 are preferably made of a metal material having a high proof stress in order to cope with the impact of high oil pressure and prevent deformation caused by the use of high oil pressure for a long time. The above are potential embodiments of the sleeve protrusion 40, and specific embodiments include, but are not limited to, the above embodiments.

The overall shape of cannula 12 (e.g., excluding cannula boss 40) may be cylindrical or nearly cylindrical, such as cylindrical, or polygonal (three, four, five, six, twenty, and more, abbreviated herein for ease of writing only) cylindrical. The inner wall of the casing 12 and the left side of the attachment 22 need to design a sufficient movement space (the movement space of the present invention, which refers to the movement space of the open-mouth trigger device 23, is distinguished from the movement space 28 of the present invention) to facilitate the open-mouth trigger device 23 to be triggered and rebounded. As a counter example, the inner wall of the casing 12 cannot be of a design that is complementary to the shape of the attachment 22 (e.g., a complementary frustoconical design) without reserving sufficient space for movement.

In a preferred embodiment, the sleeve protrusion 40 is located near the front side of the attachment body 22, or/and cooperates with the pressure spring 19 with a larger spring force, in such an embodiment, the loosening/deformation/opening of the clamping member 24 caused by the oil pressure impact will become smaller, thereby reducing the possibility of oil leakage.

The above-mentioned operating mechanism between the pressing handle and the sleeve can be realized by the ordinary technical knowledge of the person skilled in the art, for example, at least refer to prior art 1 or 2.

In some embodiments, the connector 10 further comprises a compression spring/second spring 19, the compression spring 19 being compressed during the backward movement of the sleeve 12 after the user applies (or removes) the user pressure, so as to reach the mouth-open state/ready-to-bite state; when the pressurizing handle removes (or applies) the user-provided operating pressure, the pressurizing spring 19 will expand and return to its original shape, thereby achieving the snap-in/default state.

In some embodiments, the connector 10 further includes a plunger 13, the plunger 13 having a plunger channel/first channel 16 therein for allowing grease to pass through the plunger 13 from the grease inlet 15, the plunger channel may have a smaller channel diameter than the grease inlet 15 to increase the grease pressure for easier impact on the ball valve 17 to open the grease channel (passage). The plunger 13 may be made of a soft material, such as rubber, plastic, etc., so as to achieve better sealing between the ball valve 17 and the plunger channel; the plunger 13 may be made of metal (iron, steel, manganese steel, boron steel, copper, aluminum, titanium, alloy, etc.). The plunger 13 may be integrally formed with the body, or may be fixed inside the body 11 by a fixing protrusion 14.

In some embodiments, the plunger 13 can reciprocate axially in the direction of oil delivery, i.e., no longer includes the fixed protrusion 14, which is advantageous in that a certain degree of suck-back of grease in the body passage 20 can be performed when oil delivery is stopped.

In some embodiments, the forward end of the ball valve 17 is held against by a back-stop/first spring 18, so that when the plunger channel 16 is at a low oil pressure (which is typical when the user terminates the filling), the ball valve blocks the outlet of the plunger 16, thereby preventing forward delivery of grease, while also preventing backward flow of grease.

In some embodiments, the front of the back-resisting spring 18 also includes a portion extending toward the center of the connector 10 that forms a body/second passage 20. Which in addition to providing a grease passage may also be used to attach the front end of the reaction spring 18. The extension part and the body can be integrally formed or can be arranged in the body.

In some embodiments, the connector 10 further includes an attachment body/attachment platform 22 (sometimes referred to as a sandwich core) of the clip. The attachment body 22 is a means for providing an attachment function for the clamping member 24. the clamping member 24 is attached to the outer periphery of the attachment body 22 and has an attachment body passage/third passage 30 therein, the attachment body passage 30 communicating with the body passage 20 for transferring grease from the body passage 20. The attachment body 22 may be fixedly attached to the body 11 (although detachable, it is fixedly attached to the body when assembled) by means of the attachment body fastening threads 29 of the clamp. The user can remove the attachment 22 by means of the fixing thread 29 and can also screw it into the body 11 by means of the fixing thread 29.

In some embodiments, the attachment body 22 can be implemented as a rotating body, i.e., can be rotated from a cross-section. But it may also be a non-rigid body, e.g. a body that is entirely in the shape of a rotor, but some parts are not rigid bodies, in which embodiment this arrangement is allowed.

In some embodiments, the attachment body 22 may be implemented to include a plurality of flat surfaces in a manner that facilitates the conforming of the clip 24.

In some embodiments, the outer diameter of the left/rear side (the side away from the nozzle tip 50) of the attachment body 22 is smaller than the outer diameter of the right/front side (the side close to the nozzle tip 50), and the whole body can be in a frustum shape (small left and large right), such as a truncated cone or a multi-plane frustum. The purpose of this design is to achieve that the attachment body 22 leaves sufficient space with the inner wall of the cannula 12 on the left to accommodate sufficient movement of the mouth-opening triggering means 23.

In some embodiments, a first sealing ring 21 may also be provided to seal between the attachment body 22 and the body 11. The first seal ring 21 may be located on the rear side of the attachment body 22, may be located on the outer periphery of the rear side of the attachment body 22, or both of them may be provided with the first seal ring 21, and the first seal ring 21 is located between the interfaces of the main body 11 and the attachment body 22.

In some embodiments, the attachment body 22 is integrally formed with the body 11 (herein, non-detachably and fixedly disposed on the body, and still "fixedly disposed"), and the fixing thread 29 and the first sealing ring 21 are not required therebetween. In this type of embodiment, the body 11 and the attachment body 22 can be regarded as one component, but those skilled in the art know that the component can be regarded as two components by human division, and implementing it as one component does not avoid that it can be regarded as two components.

In some embodiments, the front/outlet port of the attachment body 22 includes a second sealing ring 26 for sealing the seal between the attachment body 22 and the nipple 50 of the connector 10.

In certain embodiments, the second seal ring 26 is not in the form of a conventional "ring" seal, but rather in the form of a gasket seal to enhance the ability of the connector to cope with the problem of high oil pressures impacting/flushing seals thereat.

In some embodiments, the holder 24 comprises two ends (mouthpiece trigger 23, the gripping teeth 25 of the holder) and one central projection 27. The mouth opening trigger 23 may be a broken line/surface, or may be an arc/surface, such as a circular arc/surface. The mouth-opening triggering means 23 can be triggered/contacted by the sleeve protrusion 40 during the backward movement of the sleeve protrusion 40, so that the biting teeth 25 of the lifting jig 24 move away from the central axis of the connector 10 (or the jig 24), thereby achieving the mouth-opening action of the jig 24. The broken lines, the arc lines and the circular arc lines are all descriptions under a section view angle, and the broken surface shapes, the arc surface shapes and the spherical surface shapes are all descriptions under a three-dimensional view angle. The central axis may be as shown in phantom in fig. 1. The number of the clamping members 24 may be 3, 4, 5, 6, 7, 8, 20 (omitted here for convenience of writing, and the omitted part is not disclosed), and more. The clip 24 may be disposed about a central axis of the clip 24/connector 10. The material of the clamp 24 may be metal (iron, steel, manganese steel, boron steel, copper, aluminum, titanium, alloys, etc.).

The open-mouth trigger 23 needs to be designed such that it will contact the sleeve protrusion 40 on the sleeve 12 during the backward movement of the sleeve 12 and effectively prevent the sleeve protrusion 40 from crossing the open-mouth trigger 23 and thus preventing the holder 24 from risking to be detached from the attachment 22. The above object can be achieved by arranging the open-mouth trigger 23 with a suitable extension length or/and extension angle, and shape, as known to those skilled in the art, based on the general technical knowledge in the art.

In some embodiments, the mouth-opening trigger 23 is a component tilted away from the attachment 22, such as a curved sheet, a curved rod, etc.

In some embodiments, medial protrusions 27 may be inserted into grooves (in channels/slits/pits) on the outer surface of attachment body 22 and may move within attachment body 22. On the surface of the attachment body 22, there may be a groove in which the above-mentioned intermediate projection 27 is accommodated.

In some embodiments, in addition to receiving the intermediate protrusion 27, the groove includes an intermediate protrusion activation space 28 to facilitate activation/rotation of the holder during/during mouth opening. The active space 28, may be on the front side of the medial bulge. The active space 28 may have a trapezoidal or substantially trapezoidal cross section.

In some embodiments, the slot for receiving the middle protrusion 27 may be a slot wider than the thickness of the middle protrusion 27, and the slot with the trapezoidal cross section is not required to be provided, but only passes through a wider slot to allow the mouth opening and mouth closing movement of the mouth opening trigger 23. Wherein the thickness of the intermediate projection (27) is a measure of the front-rear/left-right direction dimension in the drawing, not the up-down direction.

In some embodiments, the groove may be implemented as a hemispherical pit, while the intermediate protrusion 27 is implemented as a hemispherical protrusion. In this type of embodiment, the groove does not require a clearance space 28, since the intermediate projections 27 are all mutually congruent hemispheric shapes.

In the present invention, the term "groove" refers to any suitable channel/slit/pit for accommodating the middle protrusion 27, and the shape may be a dot shape, a line shape, or other suitable shapes matched with the middle protrusion 27.

In some embodiments, the intermediate protrusion 27 and the groove are optional and may not be implemented. This section is continuously smooth with the surroundings in this type of solution, whereby the mouth-opening triggering device 23 and the right-hand section of the holding element 24 engage with each other by means of the sleeve projection 40 and the attachment body 22, thus keeping the holding element 24 relatively stable without a large horizontal displacement.

In some embodiments, the engaging teeth 25 of the holding member 24 are curved to fit the nozzle tip, and may be curved in a polygonal line or a continuous curve without an inflection point. The design is in order to realize the face contact with the glib talker, reaches better contact and centre gripping characteristic, avoids rocking, fish tail, wearing and tearing. The teeth 25 with better gripping characteristics are only technical features of certain embodiments, and at least this technical feature is not necessary in order to solve other technical problems described in the present invention. Virtually any convenient shape of the occluding teeth may be acceptable, as is conventional in the art.

In some embodiments, the biting teeth 24 may be formed in a conventional biting teeth shape, not necessarily in a manner as shown in the drawings, but merely having a curved surface that conforms to the break-away prevention surface of the nipple 50.

Referring to fig. 2, this state is a state in which the nozzle tip is completely engaged.

Referring to fig. 3, the sleeve 12 moves rearward due to the pressurizing handle, which moves the sleeve protrusion 40 rearward, and then triggers the mouth opening trigger 23, and rotates it by a certain amount to move the engaging teeth 25 away from the central axis, thereby performing the mouth opening movement of the holder 24, and thus facilitating the insertion of the nipple 50 into the connector 10. In the above technical solution, the sleeve protrusion 40 of the sleeve 12 is used in combination with the mouth-opening triggering device 23, and because the internal structure design of the internal whole of the sleeve 12 is similar to a cylinder (the claims of the present application do not limit specific shapes, and other reasonable structures including movement spaces are all applicable), and the frustum-shaped appearance design of the attachment 22, a sufficient movement space (not the protruding movement space 28) required for triggering and rebounding the mouth-opening device 23 is reserved, so that the above designs form an organic whole, and are mutually matched and cooperated to jointly realize the mouth-opening mechanism of the clamping member 24.

The foregoing is a preferred description of some embodiments of the invention and the foregoing description is only a description of some embodiments including certain features/techniques in a reasonable combination (unless it is not a logical decision) to achieve a specific reasonable embodiment. Moreover, since certain features may be avoided or replaced, and certain features may not be implemented, the foregoing fair combinations include embodiments lacking certain features. Finally, since the drawings in the specification are necessarily to scale, showing only selected embodiments, rather than all embodiments, some features may not be implemented, and some features may be implemented in other forms of substitute features/means, the drawings in the specification are not intended to be construed as a basis for the claims.

The present invention is not intended to be an exhaustive description of any details of the grease gun connector to which the present disclosure relates, and some details not described may be devised by those skilled in the art based on the knowledge of those skilled in the art. However, even if the design of the part is inventive and/or advanced, the technical features covered by the claims of the present invention can be utilized, and the technical solution also falls into the protection scope of the present invention.
