Description

Technical Field

[0001] The utility model relates to the technical field of sight twist rings, in particular to a sight twist ring with a locking function. Background Art

[0002] As we all know, the origins of scopes, or optical aiming devices, are difficult to verify. It's said that attempts to attach eyeglass lenses to gunstocks were made in Europe at least as early as the 16th century. Scopes are primarily classified into three categories: telescopic, collimating, and reflex. Telescopic and reflex sights are the most popular. These two types of scopes are primarily used during the day, and are therefore collectively referred to as daylight scopes. Night vision scopes, designed for nighttime aiming, are similar to the two aforementioned scopes, with the addition of a night vision device. These devices can be further categorized as low-light and infrared. With existing aiming devices, the user rotates the outer tube by turning a twist ring, changing the spacing between the inner tube's glass panes, thereby changing the magnification and target size. Under intense movement or impact, traditional focusing mechanisms are prone to tiny displacements, resulting in focus offset and affecting shooting accuracy. The focusing process of some scopes is more complicated, requiring users to spend more time and energy to make precise adjustments, especially in tense or emergency situations. Due to the instability of the focusing mechanism, frequent calibration and maintenance may be required, which not only consumes resources but also limits the usability of the scope. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a scope twist ring with a locking function, which has the following beneficial effects:

[0016] The torsion ring of the scope with a locking function, the cooperation of the guide block and the guide groove ensures the linear movement of the telescopic ring during the adjustment process, eliminates the possibility of angular deviation, and further improves the focusing accuracy. When the telescopic ring is pulled, the elastic component is compressed and deformed, and the gear ring leaves the annular groove, and the objective lens focusing knob ring can be used. After loosening the telescopic ring, the elastic component returns to its original shape, driving the telescopic ring to move, and the gear ring engages with the annular groove. This process ensures the locked state after focusing. After focusing is completed, the gear ring engages with the annular groove of the locking ring to form a mechanical lock, preventing the focusing mechanism from loosening due to external vibration or impact, thereby ensuring the stability and reliability of the scope during use. Due to the locking design of the focusing mechanism, the focus position changes caused by external factors are reduced, which means that the number of times the scope needs to be calibrated during its use cycle is greatly reduced, reducing maintenance costs, while also saving the shooter's time and energy.

After focusing is completed, the telescopic ring 5 is loosened, so that the elastic component 7 supports the telescopic ring 5, and the telescopic ring 5 drives the guide block 9 and the gear ring 6 to move. The guide block 9 moves linearly in the guide groove 8, thereby preventing the telescopic ring 5 from angular deviation and ensuring stable linear movement of the telescopic ring 5. The gear ring 6 engages with the annular groove of the locking ring 3, thereby locking the objective lens focusing knob ring 2 on the locking ring 3.
