Description

Technical Field

[0001] This utility model relates to the field of bowstring adjustment technology, specifically a bowstring tension adjustment device. Background Technology

[0002] Compound bows are widely used in archery competitions and training. With the increasing popularity of archery, compound bows are also gaining more and more public attention, becoming a new form of leisure and entertainment. A compound bow mainly consists of a handle assembly, limbs, and a bow wheel assembly. By holding the handle with one hand and drawing back the bowstring between the bow wheels with the other, the energy stored in the deformed bow wheel assembly is converted into the arrow's kinetic energy, allowing the arrow to be shot quickly and accurately towards the target.

[0003] The existing bowstring adjustment is generally done by adjusting the length of the bowstring (by adjusting the length of the bowstring clasp). Each adjustment requires disassembling and reassembling the bowstring, which is inconvenient, and it is also difficult to control the precision when manually clasping the bowstring. Therefore, we propose a bowstring tension adjustment device. Utility Model Content

[0004] The purpose of this invention is to provide a bowstring tension adjustment device to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bowstring tension adjustment device, comprising a first string wheel and a second string wheel, both the first string wheel and the second string wheel being equipped with string-tying posts, a first main string and a second main string being installed parallel to each other between the string-tying posts of the first string wheel and the second string wheel, the first string wheel being equipped with a first lifting adjustment member for lifting and adjusting the first main string, and the second string wheel being equipped with a second lifting adjustment member for lifting and adjusting the second main string.

[0006] Preferably, both the first and second lifting adjustment components use internal hexagon screws.

[0007] Preferably, both the first and second main strings consist of a main string body with two parallel grooves. The two ends of the first and second main strings pass through the corresponding grooves. The first lifting adjustment member is located at the groove where the first main string passes through the first main string, and the second lifting adjustment member is located at the groove where the second main string passes through the second main string.

[0008] Compared with the prior art, the beneficial effects of this utility model are: when the first main string is long, it is only necessary to lift the first main string by the first lifting adjustment component; when the second main string is long, it is only necessary to lift the second main string by the second lifting adjustment component; there is no need to disassemble the bowstring, the adjustment is more convenient, and the lifting is carried out by the internal hex screw, which makes the adjustment better controllable and more precise.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0019] Please see Figure 1-7In this embodiment of the invention, a bowstring tension adjustment device includes a first string wheel 1 and a second string wheel 4. Both the first string wheel 1 and the second string wheel 4 are equipped with string-tying posts 7. A first main string 2 and a second main string 3, parallel to each other, are installed between the string-tying posts 7 of the first string wheel 1 and the second string wheel 4. The first string wheel 1 is equipped with a first lifting adjustment member 5 for lifting the first main string 2, and the second string wheel 4 is equipped with a second lifting adjustment member 6 for lifting the second main string 3. Both the first lifting adjustment member 5 and the second lifting adjustment member 6 use hexagon socket screws. When the first main string is long, it is only necessary to lift it using the first lifting adjustment member; when the second main string is long, it is only necessary to lift it using the second lifting adjustment member. This eliminates the need to disassemble the bowstring, making adjustment convenient. Furthermore, the use of hexagon socket screws for lifting provides better control and higher precision.

[0020] The first string wheel 1 and the second string wheel 4 both include a string wheel body 11, the string wheel body 11 having two parallel string grooves 12, the two ends of the first main string 2 and the two ends of the second main string 3 respectively passing through the corresponding string grooves 12; the first lifting adjustment member 5 is located at the string groove 12 where the first main string 2 passes through the first string wheel 1, and the second lifting adjustment member 6 is located at the string groove 12 where the second main string 3 passes through the second string wheel 4, and both the first lifting adjustment member 5 and the second lifting adjustment member 6 extend into the string groove.

[0021] The working principle of this utility model is as follows: when the first main string 2 is long, it is only necessary to lift the first main string 2 by the first lifting adjustment member 5; when the second main string 3 is long, it is only necessary to lift the second main string 3 by the second lifting adjustment member 6.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
