[0002] A compound bow is a weapon made of slender pieces composed of mixed wood or bone. This laminate can create a very powerful bow. The deformation of the compound bow is during manufacturing, making its two ends bend forward (by steam treatment and forcefully pulling this laminate). This backward-bending bow can generate greater force and requires a high level of physical strength and technical operation;

[0003] The biggest feature of modern compound bows is the use of pulleys to achieve a labor-saving effect. The auxiliary rod is an auxiliary component of the compound bow, and its main function in the compound bow is to increase stability and balance, thereby improving the accuracy of shooting. Existing auxiliary rods are usually a rod body with a fixed length and cannot be telescopically adjusted, which takes up more space when not in use. Therefore, this application proposes an auxiliary rod for a compound bow that can be telescopically adjusted. Utility Model Content

[0004] The purpose of this application is to provide an auxiliary rod for a compound bow that can be telescopically adjusted to solve the problem that the auxiliary rod of the existing compound bow has a fixed length and cannot be telescopically adjusted.

Detailed implementation manner

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0027] As Figures 1-6 shown, an auxiliary rod with telescopic adjustment for a compound bow proposed in an embodiment of the present application includes:

[0028] A first rod body 1, on both opposite sides of which chutes 2 are opened along its length direction. The longitudinal section of the chute 2 is arc-shaped. One end of the first rod body 1 is provided with a grip 3. Preferably, the longitudinal section of the first rod body 1 is rectangular, and the two chutes 2 are respectively opened on both sides in its width direction;

[0029] A second rod body 4, on one side of which a groove 5 is opened. The longitudinal section of the second rod body 4 is rectangular, and the groove 5 is opened on the bottom side of the second rod body 4. A plurality of balls 6 are arranged in an array and inserted in a rolling manner on opposite sides of the inner wall of the groove 5. The balls 6 located on both sides are respectively in rolling cooperation with the two chutes 2. The first rod body 1 can slide and contract into the groove 5. By using the sliding cooperation between the balls 6 and the chutes 2, the first rod body 1 can slide and contract into the second rod body 4, or can slide and extend. Preferably, there is a gap between the outer wall of the first rod body 1 and the inner wall of the groove 5. The longitudinal section of the chute 2 is arc-shaped, and the balls 6 are in rolling cooperation with the chutes 2, so that the sliding friction resistance between the first rod body 1 and the second rod body 4 is small, and the stability of the two after sliding can be ensured;

[0030] The elastic member 7 is connected between the first rod body 1 and the second rod body 4 and is used for the sliding reset of the two. By connecting the elastic member 7 between the first rod body 1 and the second rod body 4, it not only improves the connection between the two, but also, when the first rod body 1 slides away from the second rod body 4, it can be reset under the action of the elastic member 7, so that the first rod body 1 can be retracted into the second rod body 4. In actual use, the second rod body 4 is connected to the compound bow. When drawing the string, hold the grip 3 and pull the first rod body 1, thereby driving the first rod body 1 to slide. Use the first rod body 1 and the second rod body 4 as auxiliary rods to improve stability and balance and the accuracy of shooting. When not in use, loosen the first rod body 1. Under the action of the elastic member 7, the first rod body 1 slides back to its original position and thus retracts into the second rod body 4, thereby reducing the overall occupied space;

[0031] In this solution, the first rod body 1 and the second rod body 4 form a complete auxiliary rod. The two can be telescopically adjusted through the sliding fit of the ball 6 and the chute 2. When in use, pull the first rod body 1 to slide. When not in use, under the action of the elastic member 7, the first rod body 1 slides back to its original position and thus retracts into the second rod body 4, thereby reducing the occupied space. After being telescoped, it is small and compact, convenient for storage, thus improving the practicality.

[0032] As Figure 3 and Figure 6 shown, in some embodiments, the elastic member 7 includes a limiting groove 701 opened on the inner wall of the groove 5. The first rod body 1 is provided with a limiting plate 702 slidably inserted into the limiting groove 701. There is a gap between the outer wall of the limiting plate 702 and the inner wall of the limiting groove 701. Two return springs 703 are connected between the limiting plate 702 and one side of the limiting groove 701. As Figure 1 and Figure 2 shown, this is the contracted state at this time. At this time, the return spring 703 is in the extended state. Under the action of its elastic force, the first rod body 1 and the second rod body 4 contract and overlap. When using and pulling the first rod body 1, the limiting plate 702 slides along the limiting groove 701 and compresses the return spring 703. The return spring 703 is compressed and thus stores energy. When not in use, loosen the first rod body 1. Under the elastic force of the return spring 703, the first rod body 1 automatically contracts and resets. It should be noted that the sliding fit between the first rod body 1 and the second rod body 4 is realized through the ball 6 and the chute 2, and the sliding friction between the two is small. Therefore, the return spring 703 does not need a large elasticity, only needs to be able to push the first rod body 1 to reset. Therefore, the elastic force of the return spring 703 will not affect the normal pulling of the bowstring.

[0033] As Figure 3 and Figure 6As shown, in some embodiments, two limiting rods 8 are connected to opposite sides of the inner wall of the limiting groove 701. The limiting plate 702 is slidably sleeved on the two limiting rods 8, and two reset springs 703 are respectively movably sleeved on the two limiting rods 8. By providing the limiting rods 8, they can not only guide the reset springs 703 to ensure that the elastic force of the reset springs 703 can be maximally utilized, ensuring that under the action of the elastic force of the reset springs 703, the first rod body 1 can smoothly contract and slide for reset. At the same time, the limiting plate 702 is slidably sleeved on the limiting rods 8, and the sliding fit between the two is used to improve the connectivity between the first rod body 1 and the second rod body 4, so as to ensure that after the first rod body 1 is slidably adjusted, it maintains a stable state with the second rod body 4.

[0034] As Figure 6 shown, in some embodiments, a buffer member 9 is provided on the side of the limiting groove 701 away from the reset spring 703. When the first rod body 1 is loosened, under the elastic force of the reset spring 703, the first rod body 1 will slide back to its original position. By providing the buffer member 9 in the limiting groove 701, it is used to buffer the stress brought by the reset spring 703, preventing the limiting plate 702 from directly hitting the groove wall of the limiting groove 701, so as to play a role of buffer protection.

[0035] As Figure 6 shown, in some embodiments, the buffer member 9 includes a conduit 901 provided on the inner wall of the limiting groove 701. One end of the conduit 901 is communicated with a bellows 902 with a closed end. Preferably, the free end of the conduit 901 is communicated with the outside. The bellows 902 is made of rubber material. When the first rod body 1 slides and extends, the outside air enters the bellows 902 through the conduit 901. When the first rod body 1 slides and contracts, the limiting plate 702 will hit the bellows 902. Under the action of the stress, the bellows 902 compresses and squeezes the air inside it. Utilizing the characteristics of the material deformation of the bellows 902 and the axial compression of its corrugations, and cooperating with the squeezing of the air, the stress of the impact of the limiting plate 702 is buffered, thereby improving the practicability.

[0036] As Figure 4 shown, in some embodiments, a plurality of through grooves 10 are arrayed on the first rod body 1. By penetrating and opening the through grooves 10 on the first rod body 1, the through grooves 10 can be used as weight-reducing grooves. Without affecting the strength of the first rod body 1, it can also reduce its overall gravity, making the auxiliary rod more compact and lightweight after overall contraction.

[0037] As Figure 4As shown, in some embodiments, a slot 11 is formed through the first rod body 1, a plug 12 that is inserted and matched with the slot 11 is arranged on the grip 3, and a locking member 13 for locking the grip 3 is arranged on the first rod body 1. By forming the slot 11 on the first rod body 1 and constructing the plug 12 on the grip 3 that is inserted and matched with the slot 11, the two are inserted and matched, and then locked by the locking member 13, so that the grip 3 and the first rod body 1 are detachably connected. When not in use, the grip 3 and the first rod body 1 can be disassembled and separated, which is more convenient for storage.

[0038] As Figure 5 shown, in some embodiments, the locking member 13 includes a jack 1301 formed through the plug 12, a through groove 1302 is formed in one inner wall of the slot 11, a plug rod 1303 whose end is inserted and matched with the jack 1301 is movably penetrated through the through groove 1302, a limit block 1304 is fixedly arranged on the plug rod 1303 and located in the through groove 1302, and a limit spring 1305 sleeved on the plug rod 1303 is installed between the limit block 1304 and the inner wall of the through groove 1302. When installing the grip 3, first pull the plug rod 1303 to make the limit block 1304 compress the limit spring 1305, then insert the plug 12 on the grip 3 into the slot 11, and then loosen the plug rod 1303. Under the elastic force of the limit spring 1305, the plug rod 1303 slides through the jack 1301, and the grip 3 can be locked and fixed. When it is necessary to release the fixation, only need to pull the plug rod 1303 out of the jack 1301. The way of locking and unlocking is relatively simple and convenient.
