Description

Technical Field

[0001] This utility model relates to the field of composite bow technology, specifically to a string stop with controllable braking force and a dual-purpose composite bow. Background Technology

[0002] In the National Combination Bow Competition, the string stop is a crucial component that ensures bowstring stability and is the only part that contacts the bowstring after it releases kinetic energy. It is widely used in various types of combination bows. However, traditional string stop designs are too simple, relying mainly on string stop glue for final precision intervention. But the traditional rough design of all combination bows and the unstable appearance of string stop glue accessories can affect shooting stability and accuracy, negatively impacting competition results.

[0003] Based on this, we propose a string stop with controllable braking force. By designing an adjustable braking mechanism inside the string stop, users can precisely adjust the braking force as needed and control the movement stroke of the string stop rubber, thereby improving shooting accuracy.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 -

[0026] Figure 4 A string stop with controllable braking force includes a string stop bracket 2 and a string stop adhesive 3 rotatably mounted at the opening of the string stop bracket 2, such as... Figure 2 and Figure 4 As shown, a brake sleeve 4 is also provided between the string stop adhesive 3 and the string stop bracket 2 to press the string stop adhesive 3.

[0027] In this embodiment, the pressure of the brake sleeve 4 on the string stop rubber 3 is adjustable. The user can precisely control the braking force of the string stop rubber 3 according to the needs, so that the string stop effect during the shooting process is more stable and controllable, thereby improving the shooting accuracy.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, a screw 5 is fixedly installed on the end of the brake sleeve 4 facing away from the string stop rubber 3. Two screws 5 are symmetrically arranged on the left and right sides. The screw 5 is inserted into the rod groove 7 opened on the string stop bracket 2 via the slot 6. An adjusting sleeve is also included, which is movably installed on the screw 5 and connected to the inner wall of the rod groove 7 through the spring 12. By adjusting the position of the adjusting sleeve on the screw 5, the degree of tension of the spring 12 can be adjusted, thereby controlling the pressing force of the brake sleeve 4 on the string stop rubber 3.

[0029] In this embodiment, the adjusting sleeve includes a traction sleeve 9 and a nut 11 that are rotatably connected. The nut 11 is screwed onto the screw 5. The traction sleeve 9 is connected to the inner wall of the rod groove 7 through a spring 12. In addition, a spline 10 is formed on the outer wall of the traction sleeve 9. The spline 10 is slidably disposed in the spline groove 8 opened at the end of the rod groove 7.

[0030] Thus, by rotating the nut 11, the degree of tension of the spring 12 can be controlled; the sliding of the spline 10 in the groove 8 restricts the rotation of the traction sleeve 9, allowing it to only translate.

[0031] Therefore, in this invention, by setting an adjustable braking mechanism, the movement stroke of the string stop rubber 3 can be precisely controlled, improving shooting accuracy and stability. This design effectively solves the problem of movement stroke variation caused by uneven friction in traditional string stoppers, ensuring the consistency and accuracy of braking effect in each shot.
