Description

Technical Field

[0001] The utility model relates to the technical field of launchers using a stretched rubber band as a power source, in particular to a semi-automatic slingshot. Background Art

[0002] Although the existing slingshot designs are varied and varied, the basic principle and structure are still based on the traditional Y-shaped slingshot design. They all need to be manually loaded and have a limited firing rate. In addition, the traditional Y-shaped slingshot does not have a clear and stable three-point-one-line aiming device. The angle of the shooter's gripping of the slingshot pocket, the strength and length of the rubber band each time, and the angle of the slingshot grip each time will change slightly. Therefore, novices generally cannot shoot quickly and accurately continuously. Moreover, if the posture of pulling the slingshot pocket back and holding the slingshot forward is crooked, it is very easy to cause the projectile to fly around, hit the bow gate, hands, and even hit the face and eyes after rebounding, which is very dangerous. After each shooting, you need to manually untie the tangled rubber bands, and then cooperate with both hands to put the projectile into the slingshot pocket and shoot again, which is very troublesome. Moreover, when replacing the rubber band of most slingshots, you first need to tie one end of the rubber band to the slingshot pocket, and then tie the other end to the bow fork or clamp it to the bow fork with a screw clip. This process is very demanding of skills and patience. Many people who first come into contact with slingshots lose confidence and patience with slingshots after experiencing the tedious, inaccurate and dangerous shooting mentioned above. Many people even take risks to play with guns in order to satisfy the thrill of hitting the target. This has led to the slingshot shooting sport being lukewarm, and there are only some competitive competitions organized by the public. It has never developed into a mainstream formal competitive sport. It is a pity!

[0003] In addition, the slingshots of the prior art have low shooting accuracy, low shooting speed, and poor stability, which makes them not well equipped to special forces for silent hunting in the wild to obtain food or security organizations to perform low-kinetic energy and low-noise shooting targets.

[0027] The bow tail comprises a rotating chin rest and a secondary support, wherein the secondary support is connected to the tail end of the bow body, and the rotating chin rest is hinged to the secondary support.

[0028] The utility model has the following advantages: using a feeding gear set, the projectiles in the magazine can be quickly and continuously fed into the magazine pocket through a series of gear meshing mechanical actions; the whole process only requires one hand to hold the lower grip, and the other hand to hold the releaser and push it forward to the bottom and then pinch the clip to complete the loading, and then the rubber band can be pulled to fire; the whole process is fast, accurate and smooth, the maximum firing rate exceeds 60 rounds per minute, and the shooter can experience the loading and shooting speed of a semi-automatic rifle.

[0029] Two pulleys cooperate with four rubber bands to tighten the bullet pocket and install it on the bow head. In the absence of external force, the four rubber bands at the four corners of the bullet pocket and the corresponding four pulley grooves can always position the bullet pocket in the center of the bow head. This allows the bullet pocket to accurately wrap the projectile when loading, and can also quickly reset the bullet pocket after firing the projectile, waiting for the next automatic loading and firing. There is no need to adjust the entanglement between the bullet pocket and the rubber band before and after each firing like an ordinary slingshot, which makes loading the bullet more convenient, simple, fast and accurate for the shooter.

[0030] When installing the rubber band and bullet pocket, you only need to fold the rubber band in half from the center and pass it through the rubber band hole of the bullet pocket. There is no need for complicated bundling. To connect the rubber band and the bow head, you only need to snake the end of the rubber band into the rubber band slot. There is no need for complicated bundling or clip fixing, so the shooter can install the rubber band and bullet pocket more easily and quickly.

[0031] Since the releaser and the bow head are installed on the same bow body, under the action of the guide rail, the angle and direction of the projectile are almost consistent each time it is launched. Unlike an ordinary slingshot, the bow head may be relatively skewed each time it is launched, which is both inaccurate and dangerous. The track structure adopted by the utility model can make shooting safer, more stable and accurate.

[0032] The magazine is divided into the front magazine and the rear magazine, and is made of tough transparent plastic tube material. The rear magazine is used for manual loading and also serves as a spare magazine. After pulling out the compression spring lever of the front magazine, the front magazine and the rear magazine are connected, and the bullets in the rear magazine can roll into the front magazine, and then the rear magazine can be filled again. This makes the division of labor of the magazines clear and reduces the failure rate. At the same time, it also doubles the total capacity of the magazines, allowing the shooter to achieve a longer endurance with one loading.

[0033] Since the relative positions of the bow rail and the bow head are fixed, and the firing angle and direction are also relatively fixed, a three-point-in-one-line aiming method can be achieved, and then a mechanical sight or a red dot sight can be installed above the bow head to achieve a more accurate shooting effect for the shooter.

[0034] Batteries can be installed in the lower grip to power related accessories, and the area under the bow head can be expanded to install accessories such as aiming aids or flashlights, which allows the shooter to effectively shoot targets in different lighting environments.

[0035] The entire slingshot can improve shooting efficiency, reduce the user's operating steps and complex movements, and can be widely used in shooting games, sports training and other fields. BRIEF DESCRIPTION OF THE DRAWINGS

There is no need to adjust the entanglement between the bullet pocket and the rubber band before and after each firing like an ordinary slingshot, so that the shooter can achieve a more convenient, simple, fast and accurate loading effect.

[0086] When installing the rubber band 211 and the bullet pocket 210, it is only necessary to fold the rubber band 211 in half from the center and pass it through the rubber band hole 2103 on the bullet pocket 210 without complicated bundling. The connection between the rubber band 211 and the bow head 2 only requires the rubber band end 2111 to be serpentinely inserted into the rubber band slot 202, and there is no need for complicated bundling or clip fixing, so that the shooter can install the rubber band 211 and the bullet pocket 210 more simply and quickly.

[0087] Since the relative positions of the bow body guide rail 102 and the bow head 2 are fixed, and the firing angle and direction are also relatively fixed, a three-point-one-line aiming method can be realized, and then a mechanical sight or a red dot sight can be installed above the bow head 2 to achieve a more accurate shooting effect for the shooter.

[0088] The lower grip 5 may be equipped with a battery to power related accessories, and the bow head 2 may be expanded to include accessories such as aiming aids or flashlights, which enables the shooter to effectively shoot at targets in different light environments.

[0089] The entire slingshot can improve shooting efficiency, reduce the user's operating steps and complex movements, and can be widely used in shooting games, sports training and other fields.

[0090] Example 2

During use, pushing the releaser 4 can make the rack 409 mesh with the first straight tooth portion 3011 on the first-stage combination gear 301, and drive the feeding gear group 3 to mesh and transmit, so that the projectile is clamped from the bullet transfer portion 3032 on the third-stage combination gear 303 into the bullet clamping portion 3024 on the second-stage combination gear 302, and rotated to the front of the bullet pocket clip 401, and at the same time The bullet-turning part 3032 on the three-stage combination gear 303 turns to the magazine feeding hole 208 and is pushed into a bullet by the magazine 6. The releaser is continued to be pushed, and the pocket clip 401 will push the pocket 210 to wrap the bullet. Then, the pocket clip 401 is pinched to clamp the pocket 210 wrapped with the bullet and pull the rubber band 211 backward. The process of withdrawing the rack 409 will cause the rack 409 to drive the feeding gear group 3 to reset again. During the resetting process, the bullet-turning part 3032 on the three-stage combination gear 303 will contain a bullet and rotate to the opening facing upward. At the same time, the bullet-holding part 3024 on the two-stage combination gear 302 will turn to the bullet-turning part 3032 and hold the bullet. At this time, the rack 409 is separated from the one-stage combination gear 301 to complete the automatic loading.

[0094] Transfer from the magazine 6 to the magazine pocket 401;

[0095] A rack support 214 is provided at the lower portion of the secondary gear rack 206 , and the rack support 214 is used to support the rack 409 and be slidably connected thereto.
