[0002] The existing red dot sight comprises a wind direction adjustment device and an aiming adjustment device, wherein the aiming adjustment device is used to adjust the position of the red dot on the light analyzing mirror so as to aim at the object.

[0003] See also Figure 1 The existing aiming and adjusting device comprises an adjusting screw 4, a vertical slider 41, a sealing ring 42, a lens body 5, a retaining ring 43, and a baffle 44. The lens body 5 is provided with a first channel, and the adjusting screw 4 is provided in the first channel. The lens body 5 is provided with a protrusion 51, and the sealing ring 42, the protrusion 51 and the retaining ring 43 are abutted in sequence. The vertical slider 41 is sleeved on the adjusting screw. When the adjusting screw 4 is twisted, the vertical slider 41 is driven to move up and down along the working direction of the adjusting screw 4. The vertical slider 41 can drive the lamp holder assembly to move, so as to adjust the red dot. A baffle 44 is provided below the lens body 5, and the baffle 44 can prevent water vapor or other substances from entering the interior of the sight.

[0004] However, the vertical slider 41 in the existing aiming and adjusting device can move up and down along the working direction of the adjusting screw 4.

[0008] It can be seen from the above scheme that when using the scope, the user adjusts the position of the red dot through the aiming adjustment device. The user moves the slider downward by turning the adjusting screw, and the slider can drive the lamp holder assembly to move, thereby adjusting the position of the red dot. The limit assembly is set between the limit base plate and the slider. When the user moves the slider downward by turning the adjusting screw, the slider cannot move downward due to the setting of the limit assembly, thereby protecting the limit base plate from being broken due to the downward movement of the slider, so that the scope maintains good sealing performance. The adjusting nut abuts against the annular protrusion, and the retaining ring abuts against the annular protrusion. When the user twists the adjusting nut, the adjusting screw cannot move up and down, and the adjusting screw only drives the slider to move up and down.

[0009] In a further solution, the limiting mechanism includes a limiting protrusion and a limiting fixing portion; the mirror body is provided with a fixing hole, and the limiting fixing portion is threadedly connected to the fixing hole; the limiting protrusion extends into the first working channel.

[0011] In a further solution, the limiting assembly includes a fixing mechanism, an elastic member and a limiting ball, the limiting ball abuts against a gear portion arranged on the periphery of the adjusting nut, the elastic member abuts against the limiting ball, and the fixing mechanism abuts against the elastic member.

[0012] It can be seen that when the user twists the adjusting nut, the limit pin performs a telescopic movement under the action of the elastic member, and the limit pin collides with the gear part arranged on the outer periphery of the adjusting nut, making a sound to provide feedback to the user.

[0013] In a further solution, the positionable aiming and adjusting device further comprises a sealing ring, which is sleeved on the working screw segment and abuts between the working screw segment and the adjusting nut.

[0014] In a further solution, the annular protrusion is provided with grooves arranged along the circumferential direction, and the sealing ring abuts against the groove; the sealing ring also abuts against the back of the adjusting nut.

[0015] It can be seen that the sealing ring abuts against the back of the adjusting nut to form a waterproof sealing structure, which effectively prevents water vapor from entering the working screw section and the slider.

[0016] In a further solution, a retaining ring is arranged above the adjusting nut, and the retaining ring abuts against the upper end of the adjusting nut.

[0017] It can be seen that the retaining ring can further prevent the entry of water vapor.

[0018] In a further solution, the slide block is provided with an extension portion, the lamp holder assembly is provided with a slide groove, and the extension portion is clamped in the slide groove.

[0019] It can be seen that the extension portion is clamped in the slide groove, and the slide block can drive the lamp holder assembly to move up and down.

[0020] In order to achieve the above-mentioned second purpose, the utility model provides a red dot sight, which includes the above-mentioned limitable aiming and adjusting device. BRIEF DESCRIPTION OF THE DRAWINGS
