Description

Technical Field

[0001] This utility model relates to the field of slingshot technology, and in particular to a slingshot release device. Background Technology

[0002] To increase the range and kinetic energy of a projectile after it is launched, the tension, strength, and length of the rubber band must be increased. However, this means that the user must have considerable strength, and their fingers must have a strong gripping force, and they must be able to hold the position for a certain period of time to aim at the target. Therefore, this method is difficult to aim accurately and lacks stability, balance, and durability. For this reason, slingshot release devices have appeared on the market to release projectiles. This pincer-shaped slingshot release device consists of a fixed assembly, a trigger mechanism, and a pincer-shaped movable arm assembly. The movable arm clamps the rubber band holding the projectile, and the trigger mechanism drives the movable arm to release the rubber band. In this way, the hand only needs to hold the fixed assembly, and one finger can pull the trigger to release the projectile. However, since the fixed assembly is held directly in the hand, novices often have not yet mastered the correct grip. If the hand grip is incorrect, the release position of the projectile will deviate from the center line of the slingshot, causing its release path to deviate and resulting in a failure to hit the target, as shown in the patent document with publication number CN 203949558 U. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a slingshot release device.

[0007] Preferably, the trigger mechanism includes a push block, a reset member, and a release member. The push block is movably installed in the mounting cavity. The push block abuts against the side of the connecting portion away from the clamping portion. The end of the push block away from the connecting portion is connected to the release member. The release member extends out of the fixed assembly platform. By operating the release member, the push block can be moved away from the connecting portion. The reset member abuts against the push block to drive the push block to abut against the connecting portion.

[0008] Preferably, the release component includes a push rod and a release block. The push rod is fixed to the end of the push block away from the connecting part. The ball head is provided with a connecting cylinder connected to the fixed assembly platform. The end of the push rod away from the push block is inserted into the connecting cylinder. The release block is movably installed on the side wall of the connecting cylinder. The release block can abut or release the push rod. When the push rod is abutted, the push block cannot move away from the connecting part.

[0009] Preferably, the connecting cylinder is provided with a mounting hole perpendicular to its axis, the release block can be telescopically installed in the mounting hole, at least one end of the release block protrudes from the mounting hole, the release block is provided with a clearance hole, and the push rod can pass through when the axis of the clearance hole coincides with the axis of the connecting cylinder.

[0010] Preferably, the mounting hole extends through the connecting cylinder in the radial direction, and both ends of the release block can protrude through the mounting hole; or, the mounting hole does not extend through the connecting cylinder in the radial direction, one end of the release block can protrude through the mounting hole, and a second return spring is connected between the release block and the connecting cylinder to drive the release block to move outward from the mounting hole, so as to misalign the clearance hole with the hollow part of the connecting cylinder.

[0011] Preferably, the end of the push block facing the connecting part is arc-shaped, and the connecting parts of the two movable arms are symmetrically provided with limiting protrusions facing each other. When the two limiting protrusions are in contact, they prevent the movable arms from continuing to open. A pulley is provided on the side of the connecting part that is in contact with the push block.

[0012] Preferably, the reset element is a first reset spring, which passes through the push rod. One end of the first reset spring abuts against the push block, and the other end of the reset spring abuts against the end face of the mounting cavity that connects the push block to the push rod.

[0013] Preferably, the outer edge of the end of the grip seat opposite to the opening end of the ball joint groove is provided with a protruding grip portion; the fixed assembly table is provided with a laser sight at a position away from the movable arm for assisting aiming.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a slingshot release device, which, compared with the prior art, has at least the following technical effects: 1. By universally connecting the fixed assembly platform and the grip base, when the rubber band is stretched to generate tension, the fixed assembly platform can rotate around the ball head to automatically adjust its angle, so that the direction of the release of the rubber band by the movable arm can always be aligned with the firing center of the slingshot. This effectively solves the problem of the slingshot release position deviating from the firing center due to incorrect hand grip, thereby ensuring the accuracy of shooting and improving the hit rate. Regardless of whether the user is new or old, even if there are differences in the grip posture, the slingshot release device can automatically adjust to the optimal firing angle, so that the release direction of the slingshot is always accurate, greatly improving the versatility and user-friendliness of the product, and both new and old users can easily use it. 2. The matching method of the ball head and the ball joint groove ensures that the fixed assembly platform can rotate flexibly in all directions while ensuring the connection stability between the two. During user operation, even under the tension of the rubber band, the ball head can rotate stably within the ball joint groove without loosening or falling off, making the slingshot releaser both flexible and reliable in use, improving stability and safety. 3. The connecting parts of the two movable arms are symmetrically located in the mounting cavity, making the entire slingshot releaser structure more compact and symmetrical, improving the product's aesthetics and ensuring even force distribution on the projectile during release, further improving hit rate and reliability. 4. The trigger mechanism includes a push block, a reset component, and a release component. The push block abuts against the connecting part of the movable arm. By operating the release component, the push block moves away from the connecting part, allowing the connecting part to rotate around the hinge point. This enables the clamping parts of the movable arms to release the projectile, achieving precise control over the release timing, improving release stability and reliability, and ensuring the projectile flies along the expected trajectory. The reset component drives the push block to abut against the connecting part, preventing the movable arm from moving and ensuring the movable arm returns to its original position after the projectile is released. 5. The release mechanism includes a push rod and a release block. The push rod is fixed to the end of the push block opposite the connecting part and passes through the connecting cylinder. The release block is movably mounted on the side wall of the connecting cylinder. The movement of the push block is controlled by the release block pressing against or releasing the push rod, making the operation and release position closer to the hand gripping part. This allows the user to operate the release of the projectile with one hand, requiring only a light press with the thumb, making operation simple and convenient. 6. The release block has a clearance hole. When the axis of the clearance hole coincides with the axis of the connecting cylinder, the push rod can pass through smoothly, allowing the push block connected to it to be pushed back by the connecting part to achieve the rotation of the movable arm to release the projectile. 7. When both ends of the release block protrude from the outer wall of the connecting cylinder, the clearance hole and the hollow part of the connecting cylinder can be misaligned by pressing the release block with a finger, thus blocking the push rod. Conversely, if only one end protrudes, the clearance hole is returned to the misaligned state by a return spring. 8. Set limit protrusions to prevent the movable arm from rotating too much inward, which could cause the movable arm to jam or fail to hold the projectile.9. The reset element uses a first reset spring, which passes through the push rod, with its two ends abutting against the corresponding end faces of the push block and the mounting cavity, respectively. This structure provides a stable and reliable reset force for the push block, ensuring that after the release element is operated, the push block can quickly and accurately reset to its initial position, preparing for the next clamping and release of the projectile. 10. The outer edge of the end of the grip seat opposite to the opening of the ball joint groove has a protruding gripping part. This design increases the gripping area of ​​the grip seat, allowing the user's fingers to better fit and support the grip, improving grip comfort and stability. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figures 1 to 10 A slingshot release device includes a movable arm 1 and a fixed assembly platform 2. The movable arm 1 is mounted on the fixed assembly platform 2, and the fixed assembly platform 2 is provided with a trigger mechanism 3. The trigger mechanism 3 is throttle-connected to the movable arm 1 and is used to drive the movable arm 1 to release a projectile 6. The fixed assembly platform 2 is connected to a grip 4, and a universal joint is connected between the grip 4 and the fixed assembly platform 2. The grip 4 is used for user gripping. By omnidirectionally connecting the fixed assembly platform 2 to the grip base 4, when the rubber band is stretched and generates tension, the fixed assembly platform 2 can rotate around the ball head 5 to automatically adjust its angle, ensuring that the direction of release of the rubber band by the movable arm 1 is always aligned with the firing center of the slingshot. This effectively solves the problem of the release position of the projectile 6 deviating from the firing center due to incorrect hand grip, thus ensuring shooting accuracy and improving the hit rate. Regardless of whether the user is new or experienced, even if there are differences in grip posture, the slingshot release device can automatically adjust to the optimal firing angle, ensuring that the release direction of the projectile 6 is always accurate, greatly improving the product's versatility and user-friendliness, allowing both new and experienced users to easily get started.

[0034] Please see Figures 1 to 7 , Figures 9 to 10Preferably, the universal joint is a ball joint groove located in the grip base 4, and a ball head 5 fixedly connected to the side of the fixed assembly platform 2 opposite to the movable arm 1, the ball head 5 being engaged in the ball joint groove. This engagement between the ball head 5 and the ball joint groove ensures both flexible omnidirectional rotation of the fixed assembly platform 2 and stable connection between the two. During user operation, even under the tension of the rubber band, the ball head 5 can rotate stably within the ball joint groove without loosening or falling off, making the slingshot release device both flexible and reliable in use, improving stability and safety. Of course, a universal joint can also be used, and it is not limited to this.

[0035] Please see Figures 1 to 10 Preferably, the fixed assembly platform 2 has a mounting cavity. The movable arm 1 includes a clamping part 12 and a connecting part 11. The clamping part 12 is fixed to the connecting part 11, and the connecting part 11 passes through the mounting cavity. The connecting parts 11 of the two movable arms 1 are symmetrically arranged in the mounting cavity. The connecting parts 11 are hinged to the mounting cavity. The trigger mechanism 3 is connected to the side of the connecting part 11 away from the clamping part 12, and can drive the connecting part 11 to move around the hinge point. The symmetrical arrangement of the connecting parts 11 of the two movable arms 1 in the mounting cavity makes the structure of the entire slingshot release device more compact and symmetrical, which helps to improve the appearance of the product. At the same time, it also helps to ensure that the projectile 6 is subjected to uniform force during release, further improving the hit rate and reliability of use.

[0036] Please see Figures 1 to 10 Preferably, the trigger mechanism 3 includes a push block 31, a reset member 32, and a release member. The push block 31 is movably installed in the mounting cavity. The push block 31 abuts against the side of the connecting part 11 away from the clamping part 12. The end of the push block 31 away from the connecting part 11 is connected to the release member. The release member extends out of the fixed assembly platform 2. By operating the release member, the push block 31 can be moved away from the connecting part 11. The reset member 32 abuts against the push block 31 to drive the push block 31 to abut against the connecting part 11. The trigger mechanism 3 includes a push block 31, a reset member 32, and a release member. The push block 31 abuts against the connecting part 11 of the movable arm 1. By operating the release member, the push block 31 is moved away from the connecting part 11, and the connecting part 11 can rotate around the hinge point, so that the clamping part 12 of the movable arm 1 can release the projectile 6. This can achieve precise control of the release timing of the projectile 6, improve the stability and reliability of the release, and ensure that the projectile 6 can fly according to the expected trajectory. The function of the reset member 32 is to drive the push block 31 to abut against the connecting part 11 to prevent the movable arm 1 from moving, and ensure that the movable arm 1 can reset after the projectile 6 is released.

[0037] Please see Figures 1 to 10Preferably, the release component includes a push rod 33 and a release block 34. The push rod 33 is fixed to the end of the push block 31 away from the connecting part 11. The ball head 5 is provided with a connecting cylinder 51 connected to the fixed assembly platform 2. The end of the push rod 33 away from the push block 31 is inserted into the connecting cylinder 51. The release block 34 is movably installed on the side wall of the connecting cylinder 51. The release block 34 can abut or release the push rod 33. When the push rod 33 is abutted, the push block 31 cannot move away from the connecting part 11. The release mechanism includes a push rod 33 and a release block 34. The push rod 33 is fixed to the end of the push block 31 away from the connecting part 11 and passes through the connecting cylinder 51. The release block 34 is movably installed on the side wall of the connecting cylinder 51. The movement of the push block 31 is controlled by the release block 34 pressing against or releasing the push rod 33, so that the operation release position is closer to the part held by the hand. This allows the user to operate the release of the projectile 6 with just one hand by extending the thumb and pressing lightly, making the operation simple and convenient.

[0038] Please see Figures 1 to 10 Preferably, the connecting cylinder 51 has a mounting hole perpendicular to its axis. The release block 34 is telescopically mounted in the mounting hole, with at least one end of the release block 34 extending out of the mounting hole. The release block 34 has a clearance hole 341. When the axis of the clearance hole 341 coincides with the axis of the connecting cylinder 51, the push rod 33 can pass through. The release block 34 has a clearance hole 341. When the axis of the clearance hole 341 coincides with the axis of the connecting cylinder 51, the push rod 33 can pass smoothly through, allowing the push block 31 connected to it to be pushed backward by the connecting part 11 to achieve the rotation of the movable arm 1 to release the projectile 6.

[0039] Please see Figures 1 to 10 Preferably, the mounting hole extends through the connecting cylinder 51 radially, and both ends of the release block 34 can protrude through the mounting hole. Alternatively, the mounting hole does not extend through the connecting cylinder 51 radially, and one end of the release block 34 can protrude through the mounting hole. A second return spring 35 is connected between the release block 34 and the connecting cylinder 51 to drive the release block 34 to move outward from the mounting hole, thereby misaligning the clearance hole 341 with the hollow portion of the connecting cylinder 51. This solution is adopted in this embodiment. When both ends of the release block 34 protrude through the outer wall of the connecting cylinder 51, the clearance hole 341 can be misaligned with the hollow portion of the connecting cylinder 51 by pressing the release block 34 with a finger, thus blocking the push rod 33; conversely, if only one end protrudes, the clearance hole 341 is driven back to the misaligned state by the return spring.

[0040] Please see Figure 1 , Figure 2 , Figures 4 to 7 , Figure 9 , Figure 10 Preferably, the end of the push block 31 facing the connecting part 11 is arc-shaped, and the connecting parts 11 of the two movable arms 1 are symmetrically provided with limiting protrusions 111 facing each other. When the two limiting protrusions 111 contact, they prevent the movable arms 1 from continuing to open. A pulley 13 is provided on the side of the connecting part 11 that contacts the push block 31. The limiting protrusions 111 are provided to prevent the movable arms 1 from rotating excessively inward, causing them to jam or fail to hold the projectile 6. The arc shape is an arc that bulges outward from the middle. The pulley 13 changes the sliding friction between the connecting part 11 and the push block 31 into rolling friction, which helps to reduce friction and extend service life.

[0041] Please see Figure 1 , Figure 2 , Figures 4 to 7 , Figure 9 , Figure 10 Preferably, the reset element 32 is a first reset spring, which passes through the push rod 33. One end of the first reset spring abuts against the push block 31, and the other end of the reset spring abuts against the end face of the mounting cavity facing the push block 31 connected to the push rod 33. The reset element 32, which is a first reset spring, passes through the push rod 33, with its two ends abutting against the corresponding end faces of the push block 31 and the mounting cavity, respectively. This structure can provide a stable and reliable reset force for the push block 31, ensuring that after the release element is operated, the push block 31 can quickly and accurately reset to its initial position, preparing for the next clamping and release of the projectile 6.

[0042] Please see Figures 1 to 7 , Figures 9 to 10 Preferably, the outer edge of the end of the grip 4 opposite to the opening of the ball joint groove has a protruding grip portion; the fixed assembly platform 2 is provided with a laser sight 8 at a position away from the movable arm 1 for assisting aiming (a Picatinny rail can be provided on the back or front of the fixed assembly platform 2, and the laser sight 8 is fixed on the Picatinny rail. The structure of the laser sight 8 and the Picatinny rail are mature existing technologies and will not be described in detail or subject to specific protection requirements. Alternatively, the laser sight 8 can be directly fixed to the fixed assembly platform 2. Preferably, this case adopts a fixed integrated method). The protruding grip portion on the outer edge of the end of the grip 4 opposite to the opening of the ball joint groove increases the grip area of ​​the grip 4, allowing the user's fingers to fit and be supported better when gripping, thus improving the comfort and stability of the grip.

[0043] The working principle of this utility model is as follows:

[0044] The projectile 6 is placed in the projectile bladder of the slingshot, and the movable arm 1 is opened outwards slightly (at this time, the clearance hole 341 on the release block 34 coincides with the axis of the connecting cylinder 51, and the push block 31 can move backwards to allow the movable arm 1 to rotate). The projectile bladder is placed in the rear position of the two movable arms 1. The movable arms 1 are released, and the first reset member 32 drives the push block 31 to push against the connecting part 11, causing the two connecting parts 11 to deflect outwards around the hinge point. The clamping part 12 will then approach each other and close to clamp the bladder strap of the rubber band. The push rod 33 exits from the clearance hole 341 and is misaligned. In this way, the projectile 6 is fixed between the two movable arms 1.

[0045] Then, hold the slingshot with one hand and grasp the grip part of the grip seat 4 with the other hand, pulling it away from the slingshot. This will stretch the slingshot's rubber band. At this time, the rubber band will exert force on the clamping part 12. However, because the push block 31 is pressed against the connecting part 11, and the push block 31 is blocked by the push rod 33 and the release block 34 and cannot move backward to make way, the connecting part 11 cannot rotate around its hinge point, that is, the movable arm 1 cannot be opened. Therefore, the rubber band is stretched and the tension is transmitted to the fixed assembly platform 2. The fixed assembly platform 2 then rotates around the ball head 5 to automatically adjust its angle (so that...). The resultant force of its tension is automatically adjusted to pass through the center of the ball head 5, so that the direction of release of the elastic band by the movable arm 1 can always be aligned with the firing center of the slingshot; then, by pressing the release block 34 with one finger of the hand holding the grip, the release block 34 moves so that the clearance hole 341 coincides with the axis of the connecting cylinder 51 (that is, coincides with the axis of the push rod 33), the slingshot will tend to dislodge, and exert a force on the movable arm 1 to move away from each other. The force is transmitted to the push block (greater than the force of the first spring). Since the release block is lost, The movable arm 1 can rotate around the hinge point of the connecting part 11 and push the push block 31 towards the ball head 5 (during this process, the push rod 33 moves towards the ball head 5 and passes through the clearance hole 341 to make way) until the two movable arms 1 open a sufficient distance so that the projectile bladder can pass through and release the projectile 6; after the projectile 6 is released, the movable arm 1 loses the tension of the rubber band, and the force transmitted from the connecting part 11 to the push block is less than the force of the first return spring. The push block is pushed away from the ball head 5 by the first return spring. As the push block 31 moves in the direction of contact, the arc-shaped part of the push block 31 abuts against the connecting part 11 and swings outward around the hinge point, causing the clamping parts 12 to approach each other. At the same time, the push rod 33 is carried by the push block 31 to move away from the ball head 5, and then exits from the clearance hole 341 of the release block 34. The release block 34 is then reset by the force of the second spring and misaligned with the connecting cylinder 51. At this time, the push rod 33 cannot pass through the release block 34 to move towards the ball head 5, thus achieving the effect of not being able to unlock and release the projectile 6 without pressing the release block 34, thereby realizing self-locking.
