[0001] The utility model relates to the technical field of bows and arrows, in particular to a central axis adjustment structure of a bow and arrow sight. Background technology:

[0002] At present, sights are often used for aiming during archery. Commonly used sights include mechanical sights and electronic sights. Among them, electronic sights need to be installed through a sight bracket when in use. In addition to the installation and fixing function, the sight bracket also needs to adjust the front, back, left, right, up and down positions of the electronic sight. On September 29, 2024, the applicant submitted a patent application with application number 2024223888204 and the name of a multi-angle adjustable bow and arrow electronic sight bracket. It can achieve multi-angle adjustment of the electronic sight by designing multiple adjustment structures. However, the lateral adjustment rod and the front and rear adjustment seat at the top of the anchor are fixedly connected. The sight can only be centered in the horizontal direction, and the left and right angle adjustment function of the sight in the horizontal direction cannot be achieved. As a result, the position of the sight is lacking when adjusting, affecting the precise adjustment and use of the electronic sight.

[0003] In summary, how to realize the horizontal left and right angle adjustment function of the sight has become a technical problem that needs to be solved urgently in the industry. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a bow and arrow sight center axis adjustment structure, which solves the problem that the previous sight adjustment structure cannot achieve left and right angle adjustment of the sight in the horizontal direction.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A bow and arrow sight center axis adjustment structure includes a sight support rod, a sight seat and a sight, the top of the sight seat is provided with a circular groove, the center of the circular groove is provided with a threaded hole, the end of the sight support rod is provided with a circular head that matches the circular groove, the center of the circular head is provided with a through hole, the circular head and the circular groove are rotatably installed, a locking bolt passes through the through hole and is threadedly connected to the threaded hole, the screw head of the locking bolt presses the circular head and the sight seat tightly, the circular groove is provided with an opening at a position corresponding to the rod body of the sight support rod, and a movable gap margin is provided between the opening and the rod body of the sight support rod.

[0007] A groove is provided in the circular groove in the axial direction of the sight support rod and close to the opening. A protrusion is provided at the bottom of the sight support rod corresponding to the position of the groove. The protrusion is rotatably installed in the groove. A movable clearance allowance is provided between the through hole and the locking bolt, and a movable clearance allowance is provided between the circular groove and the circular head.

[0008] A circular positioning platform is provided at a position corresponding to the threaded hole in the circular groove, a circular positioning groove matching the circular positioning platform is provided at the bottom of the circular head, and a movable gap margin is provided between the circular positioning groove and the circular positioning platform.

[0009] The circular head is provided with a marking line in the axial direction of the sighting device support rod, and the sighting device seat is provided with an arc angle line corresponding to the marking line.

[0010] An operating handle is provided on the top of the locking bolt.

[0011] The screw head of the locking bolt is a hexagonal screw head, and the bottom of the operating handle is provided with a hexagonal inner groove matching the hexagonal screw head.

[0012] A gasket is provided between the screw head of the locking bolt and the round head of the sight support rod.

[0013] The utility model adopts the above solution and has the following advantages:

[0014] By providing a circular groove at the top of the sight mount and a circular head at the end of the sight support rod, the circular head is rotatably mounted between the circular groove, and a locking bolt presses the circular head and the sight mount together. After loosening the locking bolt, the circular head and the circular groove can rotate relative to each other, and the sight mount can drive the anchor to rotate horizontally left and right, thereby achieving the horizontal left and right angle adjustment function of the sight and ensuring the precise adjustment of the electronic sight. The combination of the protrusion and the groove can prevent relative displacement between the circular head and the circular groove when the locking bolt is tightened after the sight is adjusted, preventing deviation of the sight angle and ensuring the adjustment accuracy of the sight.

Specific implementation method:

[0022] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] like Figure 1-6 As shown, a bow and arrow sight center axis adjustment structure includes a sight support rod 1, a sight seat 2 and a sight 3. The top of the sight seat 2 is provided with a circular groove 4, and the center of the circular groove 4 is provided with a threaded hole 5. The end of the sight support rod 1 is provided with a circular head 6 that matches the circular groove 4. The center of the circular head 6 is provided with a through hole 7. The circular head 6 is rotatably installed between the circular groove 4, and a locking bolt 8 passes through the through hole 7 and is threadedly connected to the threaded hole 5. The screw head of the locking bolt 8 presses and fixes the round head 6 to the sight seat 2. The circular groove 4 is provided with an opening 9 corresponding to the position of the rod body of the sight support rod 1, and an active clearance margin is provided between the opening 9 and the rod body of the sight support rod 1, which will not affect the relative rotation between the sight seat 2 and the circular head 6. After loosening the locking bolt 8, the sight seat 2 and the round head 6 rotate relative to each other with the locking bolt 8 as the center, so that the sight 3 can be adjusted to the left and right angles in the horizontal direction.

[0024] A groove 10 is provided within the circular groove 4, located along the axis of the sight support rod 1 and near the opening 9. A protrusion 11 is provided at the bottom of the sight support rod 1, corresponding to the position of the groove 10. The protrusion 11 is rotatably mounted within the groove 10. After loosening the locking bolt 8, when the sight base 2 is rotated, it rotates horizontally left and right around the protrusion 11. Since there is a movable clearance between the through hole 7 and the locking bolt 8, and there is a movable clearance between the circular groove 4 and the circular head 5, the relative rotation between the sight base 2 and the circular head 6 is not affected. After the angle of the sight 3 is adjusted and it is tightened by the locking bolt 8, the cooperation between the protrusion 11 and the groove 10 can prevent relative displacement between the circular head 6 and the circular groove 4, thereby ensuring the adjustment accuracy of the sight 3.

[0025] A circular positioning platform 12 is provided in the circular groove 4 at a position corresponding to the threaded hole 5, and a circular positioning groove 13 is provided at the bottom of the circular head 6 to cooperate with the circular positioning platform 12, which can play a positioning role when the circular head 6 and the circular groove 4 are installed. Moreover, since there is a movable clearance margin between the circular positioning groove 13 and the circular positioning platform 12, the relative rotation between the sight seat 2 and the circular head 6 will not be affected.

[0026] The circular head 6 is provided with a marking line corresponding to the axial direction of the sight support rod 1, and the sight seat 2 is provided with an arc angle line corresponding to the marking line, which can be used to observe the specific values of the left and right rotation angles of the sight 3.

[0027] An operating handle 14 is provided on the top of the locking bolt 8 , and the operating handle 14 can realize the tightening and loosening of the locking bolt 8 .

[0028] The screw head of the locking bolt 8 is a hexagonal screw head, and the bottom of the operating handle 14 is provided with a hexagonal inner groove 15 that matches the hexagonal screw head.

[0029] A washer 16 is provided between the screw head of the locking bolt 8 and the round head 6 of the sight support rod 1 to ensure a tightening effect.

[0030] Working principle:

[0031] During adjustment, the locking bolt 8 is loosened by operating the handle 14, and the sight base 2 and the round head 6 can be rotated left and right in the horizontal direction with the protrusion 11 as the center. After adjusting the sight base 2 together with the sight 3 to the required angle as needed, the locking bolt 8 is tightened by operating the handle 14. When the locking bolt 8 is tightened, the cooperation between the protrusion 11 and the groove 10 can avoid relative displacement between the round head 6 and the circular groove 4, thereby ensuring the adjustment accuracy of the sight 3. After the locking bolt 8 is tightened, the left and right angle adjustment function of the sight 3 in the horizontal direction can be realized.

[0032] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0033] Anything not described in detail in the present invention is well known to those skilled in the art.
