Description

Technical Field

[0001] This utility model relates to the field of aiming scope technology, and in particular to an aiming scope with a light-shielding structure. Background Technology

[0002] A scope mainly consists of components such as an objective lens, eyepiece, reticle, adjustment wheel, and magnification ring. In actual use, strong light can cause reflections on the scope lens, which can expose the sniper's position and increase the risk of being detected by the enemy. By adding a lens hood to the scope, this reflection phenomenon can be effectively avoided, while also protecting the lens from damage and contamination. However, existing scope lens hoods have the problem of inconvenience in use.

[0003] For example, Chinese invention patent CN118274660B discloses a sight with a light-shielding structure. Although this solution achieves the function of opening or closing two light-shielding plates by rotating knob one, which drives two worm gears in opposite directions to rotate, indirectly driving two turbines to rotate, thus ensuring that the sight body can be shielded from the light, each time the light-shielding plate of the sight is opened or closed, it is necessary to rotate knob one. The operation is very cumbersome, time-consuming and laborious. In emergency situations, it is inconvenient to use and not very practical.

[0004] In view of this, a sight with a light-shielding structure is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problem of convenient use of scope hoods, this invention provides a scope with a light-shielding structure.

[0006] This utility model is achieved using the following technical solution: a sight with a light-shielding structure, including a support and a scope barrel, a rotating shaft is fixedly connected to the support, a torsion spring is sleeved on the rotating shaft, and a light-shielding cover is rotatably connected to the rotating shaft, one end of the torsion spring is fixedly connected to one side of the light-shielding cover, and the other end of the torsion spring abuts against one side of the support, a mounting and fixing mechanism is provided on the lower side of the support, and a quick-opening mechanism is provided on the lower side of the light-shielding cover.

[0007] As a further improvement to the above solution, the mounting and fixing mechanism includes a sleeve fixedly connected to the lower side of the support, and the inner side of the sleeve is fixedly connected to the outer side of the lens barrel.

[0008] As a further improvement to the above solution, the quick-opening mechanism includes a locking block that is fixedly connected to the side of the light-shielding cover near the lens barrel, and a locking block positioning mechanism that cooperates with the locking block is provided on the lower side of the sleeve.

[0009] As a further improvement to the above solution, the block positioning mechanism includes a limiting platform fixedly connected to the lower side of the sleeve, a limiting groove is formed on the limiting platform, a caliper that cooperates with the block is rotatably connected to the inner side of the limiting groove, and a caliper drive mechanism that causes the caliper to rotate is provided on the inner side of the limiting platform.

[0010] As a further improvement to the above solution, the caliper drive mechanism includes a handle rod fixedly connected to the side of the caliper away from the caliper block, the handle rod being slidably connected to the inner side of the limiting platform, and a handle rod pushing mechanism for pushing the handle rod to rotate is provided on the lower side of the limiting platform.

[0011] As a further improvement to the above solution, the handle pushing mechanism includes a spring disposed inside the limiting groove. The upper end of the spring is fixedly connected to the inner side of the limiting groove, and the lower end of the spring is fixedly connected to the upper side of the handle. A shortcut button is slidably connected to the lower side of the limiting platform, and the upper side of the shortcut button is configured to cooperate with the lower side of the handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows the caliper to release the locking block by pressing the quick button from the bottom. At this time, under the action of the locking block, the light shield can be quickly rotated and opened, which has the advantages of convenient opening and simple operation.

[0014] 2. This utility model achieves quick opening and closing of the light-shielding cover by the cooperation of the locking block and the caliper. When it is necessary to close the light-shielding cover, simply rotate the light-shielding cover downwards so that the locking block of the light-shielding cover is engaged with the caliper. It has the advantages of simple structure and easy maintenance. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figures 1-3 This embodiment of a sight with a light-shielding structure includes a support 4 and a scope barrel 1. A rotating shaft 9 is fixedly connected to the support 4, and a torsion spring 5 is sleeved on the rotating shaft 9. Please refer to... Figure 5 As shown, the torsion spring 5 is disposed around the shaft 9;

[0025] Please combine Figure 5 As shown, a light-shielding cover 3 is rotatably connected to the rotating shaft 9, one end of the torsion spring 5 is fixedly connected to one side of the light-shielding cover 3, and the other end of the torsion spring 5 abuts against one side of the support 4. An installation and fixing mechanism is provided on the lower side of the support 4, and a quick-opening mechanism is provided on the lower side of the light-shielding cover 3.

[0026] Please combine Figure 5 As shown, the mounting and fixing mechanism includes a sleeve 2 that is fixedly connected to the lower side of the support 4. The inner side of the sleeve 2 is fixedly connected to the outer side of the scope barrel 1. The sleeve 2 can be quickly mounted and fixed to the outer side of the scope.

[0027] Please combine Figure 5 As shown, the quick-opening mechanism includes a locking block 12 fixedly connected to the side of the lens cover 3 near the lens barrel 1. The lower side of the sleeve 2 is provided with a locking block positioning mechanism that cooperates with the locking block 12. It should be noted that the structure of the locking block 12 has a rounded side surface profile, which can achieve a perfect lock when it abuts against the caliper 11.

[0028] Please combine Figure 5 As shown, the locking block positioning mechanism includes a limiting platform 6 fixedly connected to the lower side of the sleeve 2. A limiting groove 8 is formed on the limiting platform 6. Please refer to... Figure 5 As shown, the limiting duct 8 is a cylindrical cavity that can be used to house the spring structure;

[0029] Please combine Figure 5 As shown, a caliper 11 that cooperates with the caliper block 12 is rotatably connected to the inner side of the limiting groove 8, and a caliper drive mechanism that causes the caliper 11 to rotate is provided on the inner side of the limiting platform 6.

[0030] Please combine Figure 5As shown, the caliper drive mechanism includes a handle 13 fixedly connected to the side of the caliper 11 away from the clamping block 12. It should be noted that the weight of the caliper 11 is greater than that of the handle 13, that is, the center of gravity of the caliper 11 and the handle 13 is eccentric. The weight of the caliper 11 is greater than that of the handle 13. However, under the action of the spring 10, the lower end of the spring 10 generates a certain pushing force on the upper end of the handle 13 in its natural state, causing the caliper 11 to rotate upward a certain distance and to squeeze and engage with the incoming clamping block 12.

[0031] Please combine Figure 5 As shown, the handle 13 is slidably connected to the inner side of the limiting platform 6, and a handle pushing mechanism for pushing the handle 13 to rotate is provided on the lower side of the limiting platform 6.

[0032] Please combine Figure 5 As shown, the handle pushing mechanism includes a spring 10 disposed inside the limiting groove 8. The spring 10 is mainly used to push and reset the handle 13.

[0033] Please combine Figure 5 As shown, the upper end of the spring 10 is fixedly connected to the inner side of the limiting groove 8, and the lower end of the spring 10 is fixedly connected to the upper side of the handle 13. The lower side of the limiting platform 6 is slidably connected to the shortcut button 7, which can slide up and down. The upper side of the shortcut button 7 is matched with the lower side of the handle 13.

[0034] The implementation principle of a sight with a light-shielding structure in this application embodiment is as follows: When it is necessary to open the light-shielding cover 3, the quick button 7 can be pressed upward from the bottom. The quick button 7 pushes the handle 13 to rotate, the spring 10 is compressed and deformed, and the handle 13 drives the caliper 11 to rotate, thereby releasing the locking block 12. At this time, the light-shielding cover 3 rotates under the action of the torsion spring 5, so that the light-shielding cover 3 rotates 90 degrees around the pivot rod 9. When it is necessary to close the light-shielding cover 3, push the light-shielding cover 3 downward, so that the locking block 12 abuts against one side of the caliper 11. The caliper 11 first reverses to force the spring 10 to compress and deform. When the locking block 12 is fully engaged inside the caliper 11, the spring 10 rebounds and pushes the caliper 11 to rotate forward through the handle 13, so that the caliper 11 locks and fixes the locking block 12, thereby realizing the function of quickly closing the light-shielding cover 3.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
