DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the following will make a clear and complete description of the technical scheme in the utility model embodiment. Obviously, the described embodiments are part of the utility model, not all. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] As shown in Figure 1 , Figure 2 and Figure 3 , a fiber optic sight includes a sight body 2 with a sight hole 21 and a mounting seat 1 for connecting with a bow and arrow, and a through slot 4 between the outer side of the sight hole 21 and the mounting seat 1, and a fiber optic 3 is wound around the outer periphery of the sight hole 21, and the winding path of the fiber optic 3 passes through the through slot 4; an installation plate 5 is arranged on the inner side wall of the sight hole 21; the end of the fiber optic 3 extends to the geometric center of the sight hole 21 through the edge of the installation plate 5 to form a sighting point 31. Specifically, the fiber optic 3 wound around the outer periphery of the sight hole 21 collects light in the surrounding environment, including natural light and artificial light, etc. After these lights enter the fiber optic 3, they propagate in the fiber optic 3 in the form of total reflection. The fiber optic 3 winding path passes through the through slot 4, and then the end of the fiber optic 3 extends to the geometric center of the sight hole 21 through the edge of the installation plate 5 on the inner side wall of the sight hole 21, the light conducts to this position in the fiber optic 3, and finally converges on the end face of the end of the fiber optic 3 to form a bright sighting point 31. The shooter observes this sighting point 31 to aim at the target, thereby realizing the function of aiming. The existence of the through slot 4 provides a reasonable path space for the fiber optic 3, without the need to specially project the winding part 22 to prevent the mounting seat 1 from affecting the winding of the fiber optic 3, thereby reducing the axial size of the sight body 2. In this way, the entire sight is more compact in structure while ensuring the function, reducing unnecessary space occupation. When mounted on the bow and arrow, it can better adapt to other parts of the bow and arrow, and will not affect the overall performance and operation convenience of the bow and arrow due to the oversize of the sight body 2. The arrangement of the through slot 4 ensures that the fiber optic 3 will not be excessively squeezed or bent when winding, ensuring the collection and transmission effect of the fiber optic 3 on the light, and ensuring that a bright and clear sighting point 31 can be stably formed.

[0029] In some embodiments of the present application, as shown in Figure 4As shown, the outer side of the sighting hole 21 includes a slightly concave winding part 22 for winding the optical fiber 3; the two convex sides of the winding part 22 form a light shielding ring 23 and a wire blocking plate 24 respectively, and the light shielding ring 23 and the aiming point 31 are located on the side of the sighting hole 21 close to the user's eyes. Specifically, the slightly concave design of the winding part 22 provides a specific space for the winding of the optical fiber 3, so that the optical fiber 3 can be tightly and orderly wound on the winding part 22, and the light shielding ring 23 is located on the side close to the user's eyes, which blocks the stray light and part of the optical fiber 3 on the winding part 22 from entering the line of sight range, so that the shooter can more clearly aim through the aiming point 31 when aiming, avoiding the interference of stray light on the observation of the aiming point 31. The wire blocking plate 24 is used to limit the position of the optical fiber 3 to prevent displacement of the optical fiber 3 during winding or use, so as to ensure that the optical fiber 3 is always in the correct position and maintain the stability of light collection and transmission.

[0030] The slightly concave winding part 22 facilitates the winding of the optical fiber 3, making the layout more regular and reasonable. The regularly wound optical fiber 3 can increase the contact area with light, improve the light collection efficiency, and even in a relatively dark environment, enough light can be collected to form a bright aiming point 31, enhancing the applicability of the sight in different lighting conditions.

[0031] In some embodiments of the present application, the edge of the light shielding ring 23 extends outwardly and is connected with the mounting seat 1, the through groove 4 is located between the outer surface of the winding part 22 and the mounting seat 1, and the opening of the through groove 4 faces away from the user's eyes. Specifically, the edge of the light shielding ring 23 is connected with the mounting seat 1 to form an integral structure, enhancing the stability between the sighting head main body 2 and the mounting seat 1. The through groove 4 is located between the outer surface of the winding part 22 and the mounting seat 1, providing a path for the optical fiber 3. Light is collected by the optical fiber 3 and conducted from the winding part 22 to the inside of the sighting hole 21 through the through groove 4 to form the aiming point 31; the opening of the through groove 4 faces away from the user's eyes, so that external light collected by the optical fiber 3 will not directly shine into the user's eyes when entering the through groove 4, avoiding glare affecting aiming. At the same time, the light shielding ring 23 can block stray light from other directions from shining into the user's eyes, further reducing light interference.

[0032] In some embodiments of the present application, the side edge of the mounting plate 5 away from the user's eye is provided with a groove 51; the optical fiber 3 is fixed at the outer surface of the winding part 22, and after winding around the winding part 22, the end of the optical fiber 3 extends from the groove 51 on the mounting plate 5 away from the side edge of the user's eye to the geometric center of the sighting hole 21, forming a sighting point 31. Specifically, the optical fiber 3 is fixed at the outer surface of the winding part 22, and the winding part 22 is used to wind the optical fiber 3 so that the optical fiber 3 can collect sufficient ambient light. The light propagates in the optical fiber 3 in the form of total reflection, and after winding around the winding part 22, the end of the optical fiber 3 extends from the groove 51 on the side edge of the mounting plate 5 away from the user's eye to the geometric center of the sighting hole 21. Due to the existence of the groove 51, the trajectory of the end of the optical fiber 3 is accurately guided, ensuring that the end of the optical fiber 3 can accurately reach the geometric center position of the sighting hole 21, and the light converges at this position to form a bright and clear sighting point 31, providing a reference for the shooter to aim.

[0033] The groove 51 on the mounting plate 5 fixes the position of the end of the optical fiber 3, so that the optical fiber 3 is not easily displaced even if it is affected by vibration or other external forces during use, ensuring the stability of the sighting point 31. During archery, the vibration generated by the bow and arrow will not easily cause the end of the optical fiber 3 to deviate from the geometric center of the sighting hole 21, always providing the shooter with a stable sighting point 31, enhancing the reliability of the sight in different use environments.

[0034] In some embodiments of the present application, the side of the mounting seat 1 facing the winding part 22 is a first groove surface 11, the surface between the winding part 22 and the mounting seat 1 where the sighting head body 2 is located is a second groove surface 25, and the through groove 4 is formed by the outer contour of the winding part 22 and the first groove surface 11 and the second groove surface 25. Specifically, the first groove surface 11 of the mounting seat 1, the second groove surface 25 of the sighting head body 2, and the outer contour of the winding part 22 together form the through groove 4, which provides a specific path space for the optical fiber 3. The optical fiber 3 is wound around the winding part 22 and passes through the through groove 4 between the winding part 22 and the mounting seat 1. The design of the through groove 4 avoids the need to intentionally protrude the winding part 22 to prevent the mounting seat 1 from affecting the winding of the optical fiber 3, so that the axial size of the sighting head body 2 can be reduced, and the structure of the entire sight is more compact. Moreover, the open structure of the through groove 4 increases the contact area of the optical fiber 3 with external light, enhancing the ability of the optical fiber 3 to collect light and capturing more light, so that the brightness of the sighting point 31 can be ensured even in a relatively dark environment, improving the applicability of the sight in different lighting conditions.

[0035] In some embodiments of the present application, the optical fiber 3 is wound in multiple turns on the winding portion 22 to form a winding portion 32, which is spaced apart from the first groove surface 11 and does not contact the first groove surface 11. Specifically, the optical fiber 3 is wound in multiple turns on the winding portion 22 to form the winding portion 32, which increases the contact area with ambient light, thereby being able to collect more natural light or artificial light. The winding portion 32 is spaced apart from the first groove surface 11 and does not contact the first groove surface 11, avoiding interference of the first groove surface 11 with the optical fiber 3, such as friction, extrusion affecting total reflection conditions of light, preventing light scattering or increasing light loss, and ensuring that light is stably transmitted in a total reflection manner inside the optical fiber 3. At the same time, it also avoids the blocking of the first groove surface 11 to the light, so that the optical fiber 3 can more fully collect light. The winding portion 32 wound in multiple turns increases the contact range of the optical fiber 3 with light, so that the sight vane can capture light in a larger range. Compared with a single optical fiber 3 collecting light, in a relatively dark environment, sufficient light can also be collected to ensure the brightness of the aiming point 31, and the applicability of the sight vane under different lighting conditions is improved.

[0036] In some embodiments of the present application, as shown in Figure 5 and Figure 6 , the wire blocking plate 24 is provided with a first opening 241 corresponding to the through groove 4. Specifically, the first opening 241 corresponding to the through groove 4 on the wire blocking plate 24 breaks the possible visual obstruction. External light can directly illuminate the part of the optical fiber 3 located in the through groove 4, increasing the contact area of the optical fiber 3 with light, so that the optical fiber 3 can collect more light. At the same time, for the operator, the first opening 241 provides a clear view when winding the optical fiber 3, facilitating the checking of whether the optical fiber 3 is correctly placed in the through groove 4 and whether the optical fiber 3 runs smoothly in the through groove 4.

[0037] In some embodiments of the present application, the wire blocking plate 24 is provided with a second opening 242 corresponding to the mounting plate 5. Specifically, after the optical fiber 3 is wound on the winding portion 22, it needs to extend from the winding portion 22 to the mounting plate 5 and then reach the geometric center of the aiming hole 21 to form the aiming point 31. The second opening 242 corresponding to the mounting plate 5 on the wire blocking plate 24 provides a smooth channel for the optical fiber 3. The optical fiber 3 in the annular groove 51 can smoothly extend from the annular groove 51 to the position of the through hole and the guide groove of the boss through the second opening 242, ensuring that the optical fiber 3 runs smoothly in this area without being hindered. The second opening 242 avoids the optical fiber 3 from being excessively bent or hindered when approaching the boss and the mounting plate 5, and the optical fiber 3 runs smoothly, ensuring that the total reflection process of light in the optical fiber 3 is not disturbed, so that the light can be stably conducted to form a stable and bright aiming point 31. When installing the optical fiber 3, the second opening 242 provides clear guidance for the operator, facilitating the accurate placement of the optical fiber 3 at the predetermined position.

[0038] In some embodiments of the present application, the end face of the fiber 3 end is planar. Specifically, the planar fiber 3 head can make the light more concentrated to form a sighting point 31, and compared with other shaped end faces, the sighting point 31 formed by the planar end face is clearer and sharper, without obvious light divergence or ghosting phenomenon. When aiming at the target, the shooter can more accurately align the sighting point 31 with the target, reduce the aiming error, and thus improve the accuracy of shooting; avoid deviation caused by changes in the aiming angle of the shooter.

[0039] In some embodiments of the present application, the mounting seat 1 is provided with a connecting hole 12 and a fixing hole 13 communicating with the connecting hole 12, the connecting hole 12 is used for inserting the mounting rod 14 connected with the bow and arrow, the fixing hole 13 is perpendicular to the axial direction of the connecting hole 12, and the adjusting screw 15 is connected in the fixing hole 13. The mounting rod 14 can be locked and unlocked by rotating the adjusting screw 15.

[0040] Specifically, the mounting rod 14 is inserted into the connecting hole 12 to preliminarily determine its position in the mounting seat 1; the fixing hole 13 is perpendicular to the axial direction of the connecting hole 12 and has the adjusting screw 15 built-in, and when the adjusting screw 15 is rotated, the end of the adjusting screw 15 moves forward and backward in the fixing hole 13. When the adjusting screw 15 is pushed forward, the end of the adjusting screw 15 pushes against the mounting rod 14, and the mounting rod 14 is tightly pressed against the inner wall of the connecting hole 12 by the friction force, so as to achieve the locking of the mounting rod 14, and make the mounting rod 14 tightly connected with the mounting seat 1 and unable to easily shake or displace; when the adjusting screw 15 is reversely rotated, the pressure between the end of the adjusting screw 15 and the mounting rod 14 is reduced, the friction force acting on the mounting rod 14 is reduced, and at this time, the locking can be released to allow the mounting rod 14 to be adjusted or disassembled in the connecting hole 12. The connecting hole 12 is used for quickly inserting the mounting rod 14 to determine the initial position, and the design of the adjusting screw 15 allows the user to easily fix the mounting rod 14 on the mounting seat 1.

[0041] Further, the mounting rod 14 is a lead screw; this is the first structure of the connection between the mounting rod 14 and the mounting seat 1, and the connecting hole 12 is also a threaded hole with threads. During installation, the lead screw is rotated, the threads of the lead screw interact with the threads of the connecting hole 12, so that the lead screw can be gradually screwed into the connecting hole 12, achieving the tight connection between the mounting rod 14 and the mounting seat 1, and the mounting rod 14 can be further fixed by tightening the adjusting screw 15.

[0042] In some embodiments of the present application, a mounting rod 14 for connecting with the bow is further included, the mounting rod 14 is provided with a convex part, the mounting base 1 is provided with a dovetail groove, the convex part can be inserted into the dovetail groove for cooperation, the mounting base 1 is provided with a fastening bolt for locking and fixing the mounting rod 14 in the dovetail groove. Specifically, this is the second structure for connecting the mounting rod 14 with the mounting base 1, by setting the dovetail-shaped convex part on the mounting rod 14, during installation, the dovetail convex part of the mounting rod 14 is inserted into the dovetail groove, then the fastening bolt on the side is tightened to tightly fix the mounting rod 14 in the dovetail groove, and the connection between the mounting rod 14 and the mounting base 1 is completed. The close cooperation between the dovetail groove and the convex part can ensure the accurate installation position of the sight.

[0043] In other embodiments of the present application, the mounting base 1 and the sighting main body can be set as an integrated structure or a detachable split structure according to the needs.

[0044] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
