Technical Field
[0001] The utility model relates to the technical field of toy guns, in particular to a counterweight deceleration firing gun. Background Art
[0002] As we all know, a launch gun is a toy gun, among which the rubber band gun is a classic toy. Most of them are made of wood or metal materials as the gun body. Through simple design, the elastic potential energy of the rubber band itself is cleverly used as power, and the rubber band itself is used as a bullet for firing.
[0003] At present, when the existing rubber band guns are in the continuous firing state, since there is no deceleration mechanism in the gear rotation, once the gear is loose, the gear will rotate at a high speed under the pull of the rubber band, which will cause the gear to loosen at the moment of firing and be pulled by the rubber band. All the rubber bands stuck on the gear will quickly fall out, thereby affecting the firing sensation and resulting in poor firing effect. Summary of the invention

When the tooth support portion of the gear support block is driven by the gear and drives the gear support block to rotate, the pushing portion of the gear support block extends to the adjacent teeth of the gear. During the continuous launch of the gear, the pushing portion of the gear is also pushed by the gear, thereby further increasing the deceleration effect of the gear and finally achieving the launch deceleration effect.

[0023] Furthermore, the gear clamp 2 is rotatably connected to the gun body 1 , the clamping portion 4 on the gear clamp 2 is clamped between the teeth of the gear 3 , and the release portion 5 of the gear clamp 2 is a trigger or is pushed by the trigger on the gun body 1 .
[0024] Furthermore, the counterweight block 7 is rotatably connected to the gun body 1 via the pinion, and the lifting end of the counterweight block 7 is rotatably connected to one end of the pull rod 9, and the other end of the pull rod 9 is rotatably connected to the pulling part 11 of the gear support block 8. When the gear 3 rotates, the teeth of the gear 3 need to overcome the resistance of the counterweight block 7, which will push the gear support block 8 to rotate. While the gear support block 8 rotates, the tooth support part 10 of the gear support block 8 disengages from the gear 3, and the pulling part 11 of the gear support block 8 pulls the counterweight block 7 to swing. After crossing one tooth position of the gear 3, the gear support block 8 enters the next adjacent tooth space again, and the counterweight block 7 is reset. When the rubber band on the next gear 3 is fired again, the gear support block 8 is pushed to rotate again to overcome the resistance of the counterweight block 7, thereby achieving the effect of firing deceleration.
[0025] Furthermore, a pushing portion 12 is provided above the gear support block 8, and the pushing portion 12 protrudes toward the direction of the gear 3. When the tooth support portion 10 of the gear support block 8 is driven by the gear 3 and drives the gear support block 8 to rotate, the pushing portion 12 of the gear support block 8 extends to the adjacent teeth of the gear 3. During the continuous launch of the gear 3, the pushing portion 12 of the gear 3 is also pushed by the gear 3, thereby further increasing the deceleration effect of the gear 3 and finally achieving the launch deceleration effect.
[0026] Furthermore, a single-shot to continuous-fire conversion cap 13 is provided at the upper end of the gear clamp 2, and the single-shot to continuous-fire conversion cap 13 is connected to the upper end of the gear clamp 2 via a rotating shaft. The single-shot to continuous-fire conversion cap 13 is rotated to extend out of the gear clamp 2 and toward the direction between the teeth of the gear 3, which is a single-shot state, and the single-shot to continuous-fire conversion cap 13 is rotated to the direction away from the direction between the teeth of the gear 3, which is a continuous-fire state.
[0027] Furthermore, a rubber band hanging groove 14 is provided on the end of the gun body 1 away from the mounting position of the gear 3 .
[0028] Furthermore, the gear clamp 2 , the gear 3 and the deceleration counterweight mechanism are all installed in a groove provided on the gun body 1 .
[0029] Furthermore, the upper end of the gear clamp 2 and the upper end of the gear 3 extend out of the top of the gun body 1 respectively.
[0030] The utility model takes the P90 gun type as an example to describe the specific structure:
[0031] The counterweight block described above can swing back and forth or up and down. As long as the gear reduction is achieved through the counterweight effect, it is within the protection scope of this patent. The following is a description of the counterweight block swinging back and forth as an example.
[0032] Since the trigger of the P90 gun is located at the front side of the gun body 1, the release portion 5 of the gear clamp 2 cannot be used as a trigger alone or cannot be pulled alone by the trigger provided on the rear side of the gun body 1. Therefore, the structure of the trigger of the P90 includes a front push block 15 and a rear push rod 16. The front push block 15 is the part exposed to the gun body 1, and the rear end of the rear push rod 16 is in contact with the release portion 5 of the gear clamp 2. By pushing the front push block 15 and the rear push rod 16 backward as a whole, the rear push rod 16 pushes the release portion 5 of the gear clamp 2 to move toward the rear side and rotate, thereby disengaging the clamping portion 4 of the gear clamp 2 from the teeth of the gear 3 and realizing the firing function. The front push block 15 and the rear push rod 16 are an integrated structure, and the trigger is connected to the gun body 1 via a compression spring.
[0033] The gun body 1 is respectively provided with a gear clamp 2, a gear 3 and a deceleration counterweight mechanism. The gear 3 is rotatably connected to the gun body 1. The gear clamp 2 is installed on the gun body 1 on one side of the gear 3. The gear clamp 2 is respectively provided with a clamping part 4 and a releasing part 5. The gear 3 is released by pushing the releasing part 5 to drive the clamping part 4 to disengage from the gear 3. The gear clamp 2 is connected to the gun body 1 via a reset spring 6. The gun body 1 on the other side of the gear 3 is installed with a deceleration counterweight mechanism. The deceleration counterweight mechanism includes a counterweight block 7, a gear support block 8, and a pull rod 9. The gear support block 8 is rotatably connected to the gun body 1. The gear support block 8 is respectively provided with a supporting tooth part 10 and a pulling part 11. The supporting tooth part 10 extends between the teeth of the gear 3. The pulling part 11 is connected to the counterweight block 7 via the pull rod 9. The counterweight block 7 is connected to the gun body 1 for limited swinging.
[0034] The gear clamp 2 is rotatably connected to the gun body 1 , and the clamping portion 4 on the gear clamp 2 is clamped between the teeth of the gear 3 .
[0035] The counterweight block 7 is rotatably connected to the gun body 1 via the pinion, and the lifting end of the counterweight block 7 is rotatably connected to one end of the pull rod 9, and the other end of the pull rod 9 is rotatably connected to the pulling part 11 of the gear support block 8. When the gear 3 rotates, the teeth of the gear 3 need to overcome the resistance of the counterweight block 7, which will push the gear support block 8 to rotate. While the gear support block 8 rotates, the tooth support part 10 of the gear support block 8 disengages from the gear 3, and the pulling part 11 of the gear support block 8 pulls the counterweight block 7 to swing. After crossing one tooth position of the gear 3, the gear support block 8 enters the next adjacent tooth space again, and the counterweight block 7 is reset. When the rubber band on the next gear 3 is launched again, the gear support block 8 is pushed to rotate again to overcome the resistance of the counterweight block 7, thereby achieving the effect of deceleration in launch.
[0036] A pushing portion 12 is provided above the gear support block 8, and the pushing portion 12 protrudes toward the direction of the gear 3. During the process in which the tooth support portion 10 of the gear support block 8 is driven by the gear 3 and drives the gear support block 8 to rotate, the pushing portion 12 of the gear support block 8 extends to the adjacent teeth of the gear 3. During the continuous launch of the gear 3, the pushing portion 12 of the gear 3 is also pushed by the gear 3, thereby further increasing the deceleration effect of the gear 3 and finally achieving the launch deceleration effect.
[0037] A single-shot to continuous-fire conversion cap 13 is provided at the upper end of the gear clamp 2, and the single-shot to continuous-fire conversion cap 13 is connected to the upper end of the gear clamp 2 via a rotating shaft. The single-shot to continuous-fire conversion cap 13 is rotated to extend out of the gear clamp 2 and toward the direction between the teeth of the gear 3, which is a single-shot state. The single-shot to continuous-fire conversion cap 13 is rotated to the direction away from the direction between the teeth of the gear 3, which is a continuous-fire state.
[0038] A rubber band hanging groove 14 is provided on the end of the gun body 1 away from the mounting position of the gear 3 .
[0039] The gear clamp 2 , the gear 3 and the deceleration counterweight mechanism are all installed in a groove provided on the gun body 1 .
[0040] The upper end of the gear clamp 2 and the upper end of the gear 3 extend out of the top of the gun body 1 respectively.
[0041] The rubber band installation and launching process is as follows:
[0042] Loading action;
[0043] Hang one end of the rubber band on the rubber band hanging groove 14 of the gun body 1, and hang the other end on the upper tooth groove of the gear 3, rotate one tooth position backward, and repeat the above steps until the required number of rubber bands is hung;
[0044] Single shot state action;
[0045] After loading, the single-shot and continuous-fire conversion cap 13 at the upper end of the gear clamp 2 is rotated until it extends out of the gear clamp 2 and faces the direction between the teeth of the gear 3, and the trigger is pulled. The rear end point of the rear push rod 16 of the trigger contacts the release portion 5 of the gear clamp 2 and continues to move backward. At this time, the lower side of the gear clamp 2 moves backward around the pin axis, and the upper part moves forward until the single-shot and continuous-fire conversion cap 13 blocks the nearest tooth position of the gear 3 and continues to move backward. The clamping portion 4 of the gear clamp 2 disengages from the tooth tip of the gear 3, and the gear 3 rotates until the single-shot and continuous-fire conversion cap 13 is blocked in front of the nearest tooth position of the gear 3. The cap 13 stops when it touches the tooth tip, and at the same time, the gear 3 at the top tooth position disengages from the tooth position and shoots out, the trigger is released, and the clamping part 4 of the gear clamp 2 blocks in front of the nearest tooth position of the gear 3 and continues to move, the single-shot and continuous-shot conversion cap 13 is disengaged, and the clamping part 4 of the gear clamp 2 touches the tooth tip to complete a firing. In this process, since only one firing is performed by pulling the trigger once, the role of the deceleration counterweight mechanism is not obvious. It can also have a deceleration effect, but for the operator, it does not affect the use effect.
[0046] Burst state action;
[0047] After loading, the single-shot and continuous-shot conversion cap 13 at the upper end of the gear clamp 2 is rotated to the direction away from the teeth of the gear 3, and the trigger is pulled. The rear end point of the rear push rod 16 of the trigger contacts the release part 5 of the gear clamp 2 and continues to move backward. At this time, the lower side of the gear clamp 2 moves backward, and the clamping part 4 of the gear 3 is disengaged from the tooth tip of the gear 3. The gear 3 rotates clockwise under the forward pulling action of the rubber band. At this time, a tooth tip on the upper side of the tooth support part 10 of the gear support block 8 pushes the tooth support part 10 of the gear support block 8 to swing counterclockwise around the pin shaft, and drives the U-shaped metal pull rod 9 and the counterweight block 7 to make a linkage movement. The bottom of the counterweight block 7 is lifted and swung clockwise. Since the counterweight block 7 is eccentric, the gear 3 will have resistance when it rotates and is pushed away to achieve the purpose of deceleration. When the counterweight is lifted to the highest point, the gear 3 is disengaged. At this time, the tooth tip of the tooth portion 10 close to the gear support block 8 continues to move to push the pushing portion 12 above the gear support block 8 to swing clockwise, pushing the counterweight that has been lifted and running by inertia to move downward in the opposite direction and be pushed back to its position. The gear 3 is decelerated for a second time due to the resistance until the counterweight block 7 returns to its position. The trigger wrench is continuously held, and the firearm will repeat the above-mentioned operation until the rubber band is finished or the trigger wrench is released. Therefore, the deceleration counterweight mechanism of this patent is suitable for guns with continuous deceleration, not just the continuous P90. After the gear 3 is released, the gear 3 can be decelerated in the rotation release process, thereby ensuring the firing sense and good firing effect. Due to the adoption of the above-mentioned structure, the utility model has the advantages of simple structure, continuous deceleration, good firing sense and good firing effect.
