Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, which are schematic structural diagrams of a binder clip in the prior art, a handle is installed at the triangular top of a clip body 1, a handle 2 is turned over, a fulcrum of the handle 2 is arranged on a connecting edge of a supporting bottom plate 11 and a clamping side plate 12, as shown in fig. 3, L1 is set as an acting arm, and F is set as an acting force. Assuming that the clamping torque of the clamp is M (determining the type of the clamp, which can be regarded as a fixed value), and F is M/L1, the larger L1 is, the smaller F is, i.e., the more labor is saved.

As shown in fig. 4 to 7, the novel labor-saving binder clip according to the invention comprises a clip body 1 and a handle 2, wherein the clip body 1 comprises a supporting bottom plate 11 and two clamping side plates 12 at two sides, the two clamping side plates 12 are formed by inwards inclining the supporting bottom plate 11 to form a clamping end 13, and the handle 2 is arranged at 1/2 length positions of the clamping side plates 12. Compare current scheme, through the position of adjusting 2 fixed points of handle, lengthened the arm of force of the handle. Taking the international binder clip No. three as an example, the acting force for opening the clip is recorded, and the summary test data is shown in table 1.3, the comparison table of the acting force at the tail end of the international binder clip handle:

TABLE 1.3 national standard comparison table for acting force at tail end of long-tail clamp handle

The data acquisition of the No. 3 national standard clamp in the table 1 is based on that the handle 2 is moved to the clamping side plates 12, the two clamping side plates 12 are arranged by the supporting bottom plate 11 in an inward inclined mode to form the clamping ends 13, and the handle 2 is arranged in the middle of 1/2 positions of the clamping side plates 12.

According to theoretical calculation, when the handle 2 moves to the middle position of the clamping side plate 12, the acting force at the tail end of the handle 2 is lengthened by one fourth relative to the moment arm of the fulcrum, and the acting force should be only two thirds. Comparing the test data in table 1, it is found that the theory and practice are completely consistent, and the binder clip of the present invention is more labor-saving and comfortable when in use.

The top of the clamping end 13 of the novel labor-saving binder clip of the invention is not required to be provided with the handle 2, so a round pipe for installing the handle 2 is omitted, as shown in fig. 8, the figure is an expansion drawing of the binder clip of the prior art, fig. 9 is an expansion drawing of the novel labor-saving binder clip of the invention, taking a national standard No. 3 clip as an example, the dimensions of each expansion drawing are as shown in the drawing identification, and the comparison calculation is carried out to obtain: the consumption of the old type No. 3 national standard clamp in the prior art is 2080 square millimeter steel, the novel labor-saving binder of the invention needs 1568 square millimeter steel, and the consumption of the novel labor-saving binder of the invention is 75.4% of the consumption of the old type No. 3 national standard clamp in the prior art, thereby greatly saving steel, reducing cost, omitting the process step of repeatedly spraying paint on a circular tube, reducing paint waste and reducing manufacturing cost.

There are three specific embodiments for implementing the present invention: 1. a handle mounting hole 14 is formed by integrally sinking the clamping side plate 12 as a reference; 2. partially concave and partially convex by taking the clamping side plate 12 as a reference to form a handle mounting hole 14; 3. the clamping side plate 12 is used as a reference, and the whole body is protruded upwards to form a handle mounting hole 14. The structures of the three schemes are respectively explained by combining schematic diagrams.

As shown in fig. 4, in a preferred embodiment of the present invention, first, bilateral symmetry cutting is performed on each side holding side plate 12, the middle cutting module is punched and stretched to form an inward concave arc-shaped groove 15, two cutting modules at both sides are stretched upward to form an upward convex semi-circular convex wrapping surface 16, the cutting module between the two convex wrapping surfaces 16 at each side is punched and stretched inward to form a semi-circular concave wrapping surface 17, the arc-shaped grooves 15, the semi-circular convex wrapping surfaces 16 and the semi-circular concave wrapping surfaces 17 arranged at intervals form a handle mounting sleeve, and the handle mounting sleeve forms a hollow handle mounting hole 14 for mounting a handle.

As shown in fig. 5, in another preferred embodiment of the present invention, the cutting module between the two convex wrapping surfaces 16 on each side in fig. 5 is punched inward as compared to fig. 4 to form an inwardly recessed reinforcing rib 18 which conforms longitudinally to the gripping side plate, and the handle mounting hole 14 penetrates the above-mentioned reinforcing rib 18, so that the reinforcing rib 18 serves again as the lower bottom surface of the fixed handle.

In another preferred embodiment of the present invention, as shown in fig. 6, unlike fig. 4, the inwardly concave arc-shaped groove 15 and the groove wrapping surfaces 17 at both sides in fig. 4 are kept flat, and the upward stretching of the cutting modules at both sides is performed only to form the upwardly convex semicircular convex wrapping surfaces 16 without performing the punching stretching, so that four upwardly convex semicircular convex wrapping surfaces 14 are formed at each side.

Another preferred embodiment of the present invention is shown in fig. 7, a left-right symmetrical cutting is performed on each side of the clamping side plate 12, the cut middle module is pressed downwards, an inward concave groove wrapping surface 17 is transversely punched at the middle part, inward concave longitudinal grooves are punched at both sides as reinforcing ribs 18, the longitudinal grooves are used as reinforcing ribs 18 to reinforce the clamping side plate 12, through holes are arranged at both sides of the reinforcing ribs 18 and at both left and right ends of the groove wrapping surface 17, the through holes are also handle mounting holes 14, the handle 2 passes through the through holes, and is clamped by the reinforcing ribs 18 and the groove wrapping surface 17 at one side of the through holes and the clamping side plate 12 body at the other side of the through holes, so as to play a role of fixing and limiting the handle.

It should be noted that the reinforcing ribs 18 on the clamping side plates 12 are longitudinally arranged along the inclined surfaces of the clamping side plates 12, the reinforcing ribs 18 and the clamping side plates 12 are integrally formed, and the reinforcing ribs 18 can increase the strength of the two clamping side plates 12 of the binder, ensure that the binder is not deformed, and improve the yield. Meanwhile, the reinforcing rib 18 is in the form of a longitudinal groove formed by self-molding and also serves as the lower bottom surface of the fixed handle 2.

The reinforcing ribs 18, the arc-shaped grooves 15, the protruding wrapping surfaces 16 and the groove wrapping surfaces 17 are formed by cutting, stamping and stretching the clamping side plate 12 body.

The invention makes full use of the tensile property of the raw materials for manufacturing the binder, the conventional binder material of the binder is No. 45 steel or 40Mn, the tensile coefficients of the two materials are more than or equal to 15%, the novel labor-saving binder of the invention makes full use of the tensile property of the materials, the tensile rate of the handle mounting sleeve at the limit position is controlled to be not more than 9.5%, for example, the length of a convex wrapping surface 16 before being stretched is 19.244, the length after being stretched is 21.08551, the tensile rate is 9.5%, and the tensile coefficient is less than 15% of the materials, while the production and manufacturing of the binder in the prior art do not utilize the characteristic of the raw materials, the invention utilizes the characteristic to omit 4 circular tubes for fixing the handle in the design, changes the external stamping and drawing molding, so that the paint is easier to be attached to the surface of the binder, thereby improving the utilization rate of the paint, reducing the waste, reducing the cost, and simultaneously reducing the area of the steel strip of the binder, saves raw materials and reduces the cost.
