Description

Technical Field

[0001] This utility model relates to the field of string adjustment technology, and in particular to a string adjustment structure mounted on a wheel assembly. Background Technology

[0002] During the use of compound bows or crossbows, it is often necessary to make fine adjustments to the string to ensure that its tension and position are at their best.

[0003] Traditional string adjustment methods have two main drawbacks: first, they require a bow-drawing device to loosen the string before adjustment, necessitating specialized machinery; second, they can only be adjusted through fixed holes, preventing arbitrary adjustment of the string tension. These limitations, to some extent, affect the performance and accuracy of compound bows and crossbows.

[0004] To address this issue, this invention provides a string adjustment structure mounted on a wheel assembly, designed to simplify the string adjustment process, improve adjustment accuracy, and ensure the stability and shooting performance of the compound bow or crossbow. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides an adjustment structure for the string installed on the wheel set. The adjustment structure is installed between the string hanging point 7 and the string groove 8 of the wheel set body 6, so that the tension can be adjusted steplessly without the need for special machines.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An adjustment structure for the string is installed on a wheelset. The adjustment structure is installed between the string hanging point 7 and the string groove 8 of the wheelset body 6. The adjustment structure is located inside the string. The adjustment structure includes a structural body, a locking component and / or an adjustment component. The position of the structural body on the wheelset body 6 is adjusted by the locking component and / or the adjustment component to push the string out.

[0008] This utility model also has the following additional technical features:

[0009] As a further specific optimization of the technical solution of this utility model: when the adjustment structure is an eccentric structure, the adjustment structure also includes a rotating shaft 1, the structure body rotates on the wheel set body 6 through the rotating shaft 1, and the structure body is locked on the wheel set body 6 by the locking assembly.

[0010] As a further specific optimization of the technical solution of this utility model: when the adjustment structure is a side-top structure, the structure body is adjusted to the position of the wheel set body 6 by the adjustment component, and the structure body is locked on the wheel set body 6 by the locking component.

[0011] As a further specific optimization of the technical solution of this utility model: the structural body is an eccentric structural body 3, and the eccentric structural body 3 is not limited by shape.

[0012] As a further specific optimization of the technical solution of this utility model: the structural body is a side-top structural body 5, and the side-top structural body 5 is not limited by shape.

[0013] As a further specific optimization of the technical solution of this utility model: the rotating shaft 1 is a pin or a locking screw.

[0014] As a further specific optimization of the technical solution of this utility model: the adjustment component is a side top screw 4.

[0016] As a further specific optimization of the technical solution of this utility model: the wheel assembly body 6 is provided with a visual scale mark.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] The design of this adjustment structure fully considers practicality and convenience. Through the flexible cooperation of the locking and / or adjusting components, precise adjustment of the string tension can be achieved. Whether using an eccentric or side-supporting structure, it can effectively push the string out, thereby achieving the purpose of adjusting the string tension. Furthermore, the structure itself is not limited by shape and can be customized according to actual needs, further improving the applicability of this adjustment structure.

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0027] Example 1

[0028] An adjustment structure for the string, installed on a wheelset, wherein when the adjustment structure is an eccentric structure, the adjustment structure is installed between the string hanging point 7 and the string groove 8 of the wheelset body 6. The adjustment structure is located inside the string. The adjustment structure includes a structural body and a locking component. By adjusting the position of the locking component and the adjustment structure body on the wheelset body 6, the string is pushed out to achieve stepless adjustment of the string tension.

[0029] The wheel assembly body 6 has at least one first limiting hole 601 and a first adjusting hole 602. The adjusting structure also includes a rotating shaft 1. The main body of the structure is an eccentric structure body 3, and the locking component is a locking screw 2. The eccentric structure body 3 is provided with a second limiting hole 301 and a second adjusting hole 302. The first limiting hole 601 and the second limiting hole 301 are aligned and limited by the rotating shaft 1, which is the centerline rotation point. The first adjusting hole 602 and the second adjusting hole 302 are aligned. By rotating the eccentric structure body 3, the alignment position of the second adjusting hole 302 and the first adjusting hole 602 is adjusted to achieve the pushing action of the string. The locking screw 2 is installed on the first adjusting hole 602 and the second adjusting hole 302, and the locking screw 2 can fix the first adjusting hole 602 in an appropriate position.

[0030] The rotating shaft 1 is either a pin or a locking screw. When it is a pin, it serves as the center rotation point. When it is a locking screw, it serves as the center rotation point and also has a locking function. The locking screw 2 serves as the main locking function. The eccentric structure body 3 is not limited by shape and includes, but is not limited to, circular, elliptical, or triangular shapes.

[0031] The optimized wheel assembly body 6 is equipped with visual scale markings, which makes it easier to see the adjustment size more intuitively.

[0032] An adjustment method for a tuning mechanism mounted on a gear train:

[0033] When the adjustment structure is in a side-top configuration, loosen the locking screw 2 and rotate the rotating shaft 1 using the included hex wrench (which can be flathead, Phillips, or other shapes). This rotation adjusts the position of the eccentric structure body 3, causing it to push against the string and adjust the tension. Once the desired position is reached, tighten the rotating shaft 1 and / or the locking screw 2 to complete the adjustment.

[0034] Example 2

[0035] An adjustment structure for the string, installed on a wheelset, wherein when the adjustment structure is a side-top structure, the adjustment structure is installed between the string hanging point 7 and the string groove 8 of the wheelset body 6. The adjustment structure is located inside the string. The adjustment structure includes a structural body, a locking component, and an adjustment component. The position of the structural body on the wheelset body 6 is adjusted by the locking component and the adjustment component, and the string is pushed out to achieve stepless adjustment of the string tension.

[0036] The wheelset body 6 has at least one third limiting hole 603 and a third adjusting hole 604. The adjusting structure includes a structural body, a locking component, and an adjusting component. The structural body is a side-top type structural body 5, the locking component is a locking screw 2, and the adjusting component is a side-top screw 4. The side-top type structural body 5 includes a fourth adjusting hole 501. The third adjusting hole 604 and the fourth adjusting hole 501 are aligned. The side-top screw 4 is installed in the third limiting hole 603. By rotating the side-top screw 4, the side-top type structural body 5 is moved, thereby adjusting the alignment position of the third adjusting hole 604 and the fourth adjusting hole 501, realizing the push-out action of the string. The locking screw 2 can fix the fourth adjusting hole 501 in the appropriate position of the third adjusting hole 604.

[0037] The optimized wheel assembly body 6 is equipped with visual scale markings, which makes it easier to see the adjustment size more intuitively.

[0038] An adjustment method for a tuning mechanism mounted on a gear train:

[0039] When the adjustment structure is in a side-top configuration, loosen the locking screw 2 and use the included hex wrench (which can be flathead, Phillips, or other shapes) to rotate the side-top screw 4. This rotation allows the side-top screw 4 to move laterally, adjusting the position of the side-top structure body 5. This causes the side-top structure body 5 to push against the string, thus adjusting the tension. Once the desired position is reached, tighten the side-top screw 4 and locking screw 2 in sequence to complete the adjustment.

[0040] Example 3

[0041] Double-string bows, crossbows, or other equipment using this type of wheeled mechanism have two main strings, symmetrically mounted vertically or horizontally. This can lead to differences in tension between the left and right main strings. Based on the adjustment structures described in Embodiments 1 and 2, when applied to double-string bows, crossbows, or other equipment using this type of wheeled mechanism, the tension of one string can be altered by adjusting the structure. This solves the problem of asynchronous movement of the left and right main strings, thereby adjusting the trajectory deviation.
