Background

As regards the fact that many people of slingshot should have an impression, as one of the most impressive toys of childhood imprints, it has been mentioned for a long time in historical records, and today, throughout the world, regarding all kinds of activities related thereto, slingshot is just like an exclusive adult sports article, and is improved and played in various forms of competitions, especially the slingshot is more of a day and a month different in shape and functional configuration, and is developed towards multifunction, high quality and precision; when the catapult is used for competitive fitness, the catapult tends to have the characteristics of an artistic collection, so that the advantages of the catapult in the aspects of today's rich competitive fitness, leisure entertainment and the like are seen.

Technical problem

In combination with the above, the observation experience makes you find that no matter what slingshot sports enthusiasts at home and abroad, or whether training alone or participating in a competition group, two basic steps before shooting a slingshot must be executed, one of which is: finding or holding a slingshot; the method comprises the following steps: and then finding the marble and solving the problems of marble placement and storage, including the aspect of carrying convenience, the relation between the marble and the bow is as if the balance beam and the weight are always separated, so that the marble is not convenient and unreasonable, and the exertion of related training efficiency and skills is always existed and limited.

It is also well known that the shape of the rubber band set used in the bow jet device today is also different: round, flat and pocket-shaped, etc., different types also brought different experience feelings for the user, different experience modes attract people to try one by one, especially for the beginner who just contacted the motion, for this reason, the bow of corresponding support head must be considered to be changed, and the bow of different types and quantity is equipped, the user not only has inconvenience in carrying, but also increases expenditure, and finally, the manufacturer naturally invests more manufacturing and operating costs, and the high-cost energy consumption, which goes against the current energy-saving and emission-reducing concept.

Technical solution

In order to achieve the purpose, the invention is realized by the following technical scheme: firstly, the structure space of a handle of a hand-held slingshot is combined for development and utilization; finally, the design and the provision of a magazine with a handle cavity, which faces the critical loading and loading problems, needs to consider how to design an access structure for quickly loading and unloading marbles! Therefore, the invention combines practical experience and analysis of the whole structure and function, finally creatively designs a permanent magnet embedded marble suspension technology, and cooperates with a magnetic suspension inlet-outlet structure comprising a U-shaped structure, and finally the problem of rapid bullet taking is easily solved; based on the innovative technology, a matched magazine is further invented, so that the problem of how to quickly supplement and supply ammunition is solved; then, the technical structure characteristics of the magazine and the magazine are combined, and the novel trigger linkage magazine is further solved and provided.

The key technology is combined to have different independent and combined effect characteristics, and further local innovation and improvement are achieved, wherein the multipurpose slingshot supporting head with unique local characteristics is provided, the multipurpose slingshot supporting head can be further connected with a pocket slingshot or a bag opening structure with corresponding characteristics and structures, and an external protruding sighting device capable of movably limiting and matching on the supporting head is further arranged, so that the overall function advantage of the multifunctional slingshot supporting head is perfected and improved.

Principle of operation

The convex magnetic suspension inlet and outlet of the magazine with permanent magnets is characterized in that the direct connection and the open state inside and outside the magazine body are kept, and balls at the inlet and outlet for standby are captured and adsorbed by a magnetic field and then kept in a relative suspension state, manual displacement or taking is not influenced due to limited magnetic field adsorption force, and fingers can fully contact the balls to pinch the balls due to the design of the U-shaped convex magnetic suspension inlet and outlet; the utility model is characterized in that the suspended marble at the mouth part has the blocking function of preventing the marble in the storage magazine from overflowing when in the standby state; it should be noted that the adsorption strength of the permanent magnet needs to be configured properly, and the adsorption strength should be greater than the impact force after the external force inertia superposition of the marble in the magazine.

The manual magazine and magazine are slightly different, and the main characteristics are that it can store balls in advance, and is convenient to carry and quickly supplement, and the shapes of the protruding magnetic suspension inlet and outlet of magazine and magazine are correspondent.

Furthermore, based on the linked magazine which is more characterized by a magazine storage and magazine supply, the push-pull rod can be provided with two built-in ends and linked with the trigger type marble spreading part for ammunition supply through a side part connecting structure, the displacement range of the push-pull rod is standard according to the diameter of a single marble or the diameter superposition distance of a specific number of marbles, and the push-pull rod on the linked magazine supply is provided with a permanent magnet and can be provided with a handle; the marble outlet of the magazine is linked to form an O-shaped opening with a basically flush section, and the marble outside the outlet is adsorbed, positioned and retained by a magnetic field for firing; the principle of the linked feeding magazine is as follows: firstly, marbles in a linked magazine are orderly adsorbed on one side of a linked push-pull rod, if the linked push-pull rod is moved downwards once, the marbles adsorbed on the upper part of the linked push-pull rod can be completely moved upwards due to jacking on a base at the lowest part, at the moment, the uppermost marbles are squeezed out of the linked push-pull rod, due to the magnetic field action of an outlet permanent magnet, the squeezed marbles are naturally captured by the linkage push-pull rod to realize transposition adsorption, then, if the linked push-pull rod is moved upwards once, the marbles positioned at the outlet of the linked magazine can be sequentially pushed out by the top end of the push-pull rod, the marbles with the tail ends pushed out are still in an adsorption pending state because the marbles are not thrown out of the magnetic field, at the same time, the marbles positioned near the lower end of the push-pull rod are captured and; the O-shaped marble outlet can also be used in a marble storage bin body as a substitute or a function supplement, and the marble needs to be matched with an external permanent magnet with the magnetic field density larger than that of the mouth of the marble to be adsorbed and taken out only when the marble outlet is used for the function of the marble inlet and outlet.

The multipurpose support head is characterized in that a flat rubber band is simply and directly embedded into a transverse hole groove and a round rubber band is laterally embedded into a longitudinal taper hole structure, and the multipurpose support head is more attractive and reasonable mainly for compressing the support head to the maximum extent; the group of lateral-entering longitudinal taper holes at the uppermost end of the supporting head can be communicated with the transverse hole groove at the top in a staggered manner, and mutual influence of through points on the surface seems to exist, but can be overcome through reasonable structural positioning; the scheme of the related construction principle, the flat rubber band and the round rubber band can not be put into the multipurpose support head simultaneously in the practical use, so that: a. when the inner ribs of the transverse hole groove are embedded for use, the inner ribs of the groove can be partially exposed in the longitudinal taper hole, and based on the phenomenon, the side-entering longitudinal taper hole is positioned in the middle of the transverse groove hole during construction, and the notch is opened in the built-in hollow sighting telescope, so that space is given to the construction of the transverse groove hole to a great extent, two ends of the transverse groove hole can be kept equal, the stress of the inner ribs of the groove can be kept balanced and stable all the time, and the influence is eliminated, and meanwhile, the phenomenon of left and right displacement of the rubber ribs can be effectively prevented; b. when the rubber band with the side-entering longitudinal taper hole is embedded for use, a supporting head with a certain thickness needs to be selected to be matched with the supporting head to avoid the point, firstly, the longitudinal taper hole is arranged at the front end part of the supporting head and completes a conical structure, the part of the extending through hole at the rear end of the supporting head becomes equal parallel holes, and the through point of the extending through hole and the transverse hole groove is completely positioned between the parallel holes of the longitudinal taper hole, so that the application and the embedding of the rubber band and the positioning steel balls of the rubber band cannot be influenced.
