[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4A high-efficiency zoom device for a scope, comprising a scope body 1, a zoom lens 2 and an automatic locking device, wherein one end of the scope body 1 is connected to the zoom lens 2 through the automatic locking device, and the automatic locking device comprises a square groove 3, a locking block 4, a locking groove 5, a slider 6, a slide groove 7, a spring 8, a bearing 9 and a pull plate 10, the top wall of one end of the zoom lens 2 is provided with the square groove 3 that passes through the inner cavity of the zoom lens 2, the locking block 4 is movably installed in the square groove 3, the outer wall of one end of the scope body 1 is provided with the locking groove 5, the locking groove 5 and the locking block 4 are adapted, and the locking block 4 and The contact side of the locking groove 5 is designed as an inclined surface. The left and right ends of the square groove 3 are provided with the sliding groove 7. The sliding block 6 is slidably installed in the sliding groove 7. The two groups of the sliding blocks 6 are respectively fixedly connected to the left and right side walls of the locking block 4. The top of the sliding block 6 is installed with the spring 8. The top of the spring 8 is fixedly connected to the top wall of the sliding groove 7. The top of the locking block 4 is installed with the pulling plate 10 through the bearing 9. In this embodiment, when it is necessary to install the variable power mirror 2 on the sight body 1 during use, first align one end of the variable power mirror 2 with the locking block 4 and one end of the sight body 1 with the locking groove 5. The end is inserted, and when the end of the sight body 1 enters the inner cavity of the variable magnification mirror 2 and the locking block 4 contacts the side wall of the sight body 1, due to the inclined surface of the locking block 4, the locking block 4 drives the slider 6, and the slider 6 drives the spring 8 to be compressed in the slide groove 7, and the locking block 4 is then stored in the square groove 3 under the action of the force. Then, when the variable magnification mirror 2 moves to the target position of the sight body 1 and the square groove 3 is aligned with the locking groove 5, the locking block 4 loses the force support and under the action of the spring 8, the slider 6 slides in the slide groove 7 and drives the locking block 4 to pop out in the square groove 3, that is, enter the locking groove 5, thereby realizing the locking of the sight body 1, and the spring The coordinated use of 8 and the locking block 4 ensures a stable connection between the scope body 1 and the zoom lens 2. This structure can prevent loosening or displacement caused by vibration or impact during use, and ensure the accuracy and reliability of the installation of the scope body 1. When the zoom lens 2 needs to be removed from the scope body 1, the pull plate 10 is manually pulled to make the pull plate 10 drive the locking block 4 to leave the locking groove 5 and enter the square groove 3. The movement of the locking block 4 can be easily controlled, and then the scope body 1 is separated from the zoom lens 2, that is, the disassembly of the scope body 1 and the zoom lens 2 is realized, which simplifies the operation steps, reduces the operation difficulty, and improves the user experience.

[0025] During actual use, the movement of the slider 6 is further guided. In this embodiment, a fixed column 11 is fixedly installed in the slide groove 7, and the slider 6 is slidably connected to the fixed column 11. The fixed column 11 serves as a guiding device for the slider 6, which ensures that the movement of the slider 6 in the slide groove 7 has a clear path and direction, and can effectively limit the movement of the slider 6 so that it can only move in a straight line on a fixed axis. This not only improves the movement accuracy of the slider 6, but also ensures the stability and reliability of the entire automatic locking device.

[0026] In actual use, it is further convenient to limit the locking block 4. In this embodiment, the length of the pull plate 10 is twice as long as the width of the square groove 3, which is further convenient to limit the locking block 4, so that the pull plate 10 has a larger operating space and freedom during operation. When unlocking is required, the user can use the pull plate 10 to operate the locking block 4 more accurately and stably, thereby improving the convenience and accuracy of the operation.

[0027] During actual use, the installation stability of the scope body 1 and the magnification lens 2 is further improved. In the present embodiment, four groups of automatic locking devices are provided and arranged in a ring shape on the side wall of the magnification lens 2. The four groups of automatic locking devices are arranged in a ring shape on the side wall of the magnification lens 2 to ensure that the magnification lens 2 can be evenly stressed when subjected to external force, thereby preventing deformation or damage caused by excessive force on a single point. Through the four groups of automatic locking devices, the magnification lens 2 can be more firmly connected to the scope body 1, reducing looseness or displacement caused by factors such as vibration or impact, thereby ensuring the accuracy and stability of the scope.

[0028] In actual use, it is further convenient to support the pull plate 10. In the present embodiment, the front and rear ends of the square groove 3 on the top wall of the zoom lens 2 are fixedly installed with fixing blocks 12. When it is necessary to unlock the zoom lens 2 and the scope body 1, it is necessary to pull the pull plate 10 and the locking block 4 out of the square groove 3 for support in turn, rotate the pull plate 10 through the bearing 9, and then place the pull plate 10 on the fixing block 12, so as to support the pull plate 10 and further facilitate the disassembly of the zoom lens 2 at a later time.

[0029] In actual use, in order to further prevent the pull plate 10 from being separated from the fixed block 12 when supporting, in this embodiment, a card slot 13 is provided on the fixed block 12, and the card slot 13 is adapted to the pull plate 10. When the pull plate 10 is supported, it is placed in the card slot 13 provided on the fixed block 12, which is convenient for limiting the pull plate 10 and preventing the pull plate 10 from being separated from the fixed block 12.

[0030] In actual use, it is further convenient for the spring 8 to extend and retract in the slide groove 7. In this embodiment, the inner diameter of the fixed column 11 is smaller than the inner diameter of the spring 8. By limiting the displacement and shaking of the spring 8 during the extension and retraction process, the smaller inner diameter of the fixed column 11 can reduce the friction and wear between the spring 8 and the slide groove 7, which helps to extend the service life of the spring 8, reduce the frequency of maintenance and replacement, and reduce the cost of use.

[0031] In actual use, the anti-slip property of the pull plate 10 is further improved. In the present embodiment, the pull plate 10 is provided with anti-slip grooves. The presence of the anti-slip grooves can effectively increase the roughness of the surface of the pull plate 10, thereby increasing the friction between the pull plate 10 and the contacting object. The increased friction helps to prevent the pull plate 10 from slipping or accidentally falling off when in use, thereby improving the safety and stability of the operation.

[0032] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
