Description

Technical Field

[0001] This utility model relates to a sight, and more particularly to a white light sight adjustment component and a refraction adjustment device. Background Technology

[0002] When using a grenade launcher, a white-light sight is required for aiming and firing at distant targets and firing positions. The operator adjusts the reticle assembly with firing tables via an adjustment mechanism, aligning the crosshair of the reticle with the target center line to achieve aiming. The reticle assembly is a crucial component of the white-light sight and requires careful control. Adjusting the reticle assembly relies on a precise movement driven by the adjustment mechanism to center the crosshair. Therefore, the accuracy of its displacement and the reliability of the mechanism must be strictly controlled and guaranteed, including the effects of various environmental conditions such as vibration and shock.

[0003] Existing white light sights use a reticle adjustment mechanism for both pitch and horizontal adjustment, sharing the same spring for lateral locking. Adjusting in only one direction can easily cause a slight movement in the other direction, resulting in errors. Furthermore, the existing reticle adjustment mechanism lacks a locking function; it relies solely on a spring to push a conical pin into the V-groove of the reticle adjustment seat. This means that during firing, the white light sight is subjected to significant impact forces, causing the conical pin to shift out of position, thus deviating the zero point of the white light sight and affecting shooting accuracy. Utility Model Content

[0004] To address the issue of zero-position offset in the aforementioned adjustment components, this invention provides a white light sight adjustment component, the specific technical solution of which is as follows:

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figures 1 to 4As shown, a white light sight adjustment assembly includes an adjustment base 1, an adjustment shaft 2, a metering spring 62, a conical pin 61, a positioning shaft 4, an adjustment roller 3, and a limiting member 5. The top of the adjustment base 1 has an adjustment groove 11, and the bottom of the adjustment base 1 has an adjustment screw hole 13 communicating with the adjustment groove 11, with the adjustment groove 11 and the adjustment screw hole 13 coaxially aligned. The adjustment shaft 2 has a locking post 21, a metering post 22, and an adjustment screw 23 arranged sequentially from top to bottom, with their diameters decreasing sequentially. The locking post 21 and the metering post 22 are both movably located within the adjustment groove 11. The adjustment screw 23 is connected to the adjustment screw hole 13. The locking post 21 has a rotating groove 25 and a positioning hole 24 communicating with the rotating groove 25. The metering post 22 has a metering hole 26. The metering spring 62 and the conical pin 61 are both movably inserted into the metering hole 26, with the conical end of the conical pin 61 movably abutting against the adjustment groove 11. The other end of the conical pin 61 is connected to the metering spring 62. The tapered pin 61 is pressed against the adjusting tooth groove 11 for quantitative adjustment when the adjusting shaft 2 is rotated; the positioning shaft 4 is movably inserted into the positioning hole 24 and is positioned opposite to the adjusting tooth groove 11, and the side of the positioning shaft 4 is provided with a limiting groove 41; the center of the adjusting roller 3 is provided with a threaded hole, the adjusting roller 3 is rotatably installed in the rotating groove 25 and is connected to the positioning shaft 4 by a thread, and the outer surface of the adjusting roller 3 is also provided with an annular adjusting groove 31; the limiting member 5 is fixed on the locking post 21 and is located in the positioning hole 24, and the bottom of the limiting member 5 slides against the adjusting groove 31. The limiting member 5 and the adjusting groove 31 can prevent the positioning shaft 4 from rotating along the axis, so that the positioning shaft 4 can only move back and forth along the axis; when the adjusting roller 3 is rotated, the adjusting roller 3 pushes the positioning shaft 4 to press against or move away from the adjusting tooth groove 11.

[0024] During adjustment, insert a flathead screwdriver into the adjustment slot 31, then rotate the screwdriver. The screwdriver drives the adjustment roller 3 to rotate, and the adjustment roller 3 drives the adjustment shaft 2 to rotate via the positioning shaft 4. The adjustment shaft 2 moves axially. When the adjustment shaft 2 rotates, the tapered pin 61 slides one notch at a time in the adjustment toothed groove 11, making a "clicking" sound. Each "click" sound is produced for each notch slid. By setting the calculated thread pitch, each "click" corresponds to a mil position on the reticle.

[0025] When locked, rotating the adjusting roller 3 clockwise causes the positioning shaft 4 to move radially toward the adjusting tooth groove 11 under the action of the limiting member 5, until the end of the positioning shaft 4 abuts against the adjusting tooth groove 11, thus locking the adjusting shaft 2 and preventing it from rotating. This solves the problem of the cone pin 61 shifting due to the huge impact force that the white light scope would experience. When unlocking, rotating the adjusting roller 3 counterclockwise moves the end of the positioning shaft 4 away from the adjusting tooth groove 11, separating the positioning shaft 4 from the adjusting tooth groove 11, allowing the adjusting shaft 2 to rotate.

[0026] The white light sight adjustment assembly can adjust the white light sight horizontally and has a locking function. When the reticle is adjusted to the appropriate position, the positioning shaft 4 is moved forward by the adjustment roller 3, and the tip of the positioning shaft 4 is stopped in the V-shaped adjustment groove 11 to ensure stability in the impact environment.

[0027] In order to improve the reliability and stability of the positioning between the positioning shaft 4 and the adjusting tooth groove 11, the end of the positioning shaft 4 is provided with a positioning tooth 42 that matches the adjusting tooth groove 11. The positioning tooth 42 is inserted into the adjusting tooth groove 11, which can effectively prevent the adjusting shaft 2 from rotating.

[0028] To improve the stability of adjustment when rotating the adjusting shaft 2 and avoid over-adjustment, two tapered pins 61 are provided, located at both ends of the metering orifice 26, and the two tapered pins 61 are connected to both ends of the metering spring 62. The two tapered pins 61 increase the friction when rotating the adjusting shaft 2, thus preventing over-adjustment.

[0029] To improve stability and prevent dust and other contaminants from entering between the adjusting stud 23 and the adjusting screw hole 13, a first sealing ring 75 is installed on the metering column 22, and a first sealing hole 15 is provided on the adjusting seat 1. The first sealing hole 15 is located between the adjusting tooth groove 11 and the adjusting screw hole 13. The cooperation between the first sealing ring 75 and the first sealing hole 15 can prevent dust, water, and other contaminants from entering between the adjusting stud 23 and the adjusting screw hole 13, ensuring the accuracy and stability of the adjustment. The first sealing ring 75 is a rubber ring.

[0030] A protective sleeve 71 can also be installed on the top of the adjusting seat 1. The protective sleeve 71 can close the adjusting tooth groove 11 and protect the internal structure. The protective sleeve 71 can be connected to the adjusting seat 1 by threads, which is convenient for disassembly and assembly.

[0031] To further improve the sealing performance, a second sealing ring 72 is installed between the adjusting seat 1 and the protective sleeve 71. The second sealing ring 72 is installed on the adjusting seat 1 and abuts against the protective sleeve 71.

[0032] In order to limit the axial position of the adjusting shaft 2, a limit ring 73 is installed at the bottom of the adjusting stud 23, and the limit ring 73 is also set opposite to the bottom of the adjusting seat 1.

[0033] Example 2

[0034] like Figure 5As shown, a white light scope refraction adjustment device includes a white light scope adjustment assembly, a limiting seat 81, a refraction member 82, a refraction spring 85, and a refraction screw 83. The limiting seat 81 has a moving hole 811. An adjustment seat 1 is mounted on the limiting seat 81 with its end inserted into the moving hole 811. The refraction member 82 is movably inserted into the moving hole 811, and the bottom of the adjusting stud 23 abuts against one side of the refraction member 82. The refraction spring 85 is located on the other side of the refraction member 82 and is mounted on the limiting seat 81. The refraction screw 83 is mounted on the limiting seat 81, with its end abutting against the refraction member 82. When the adjusting shaft 2 moves axially, it pushes the refraction member 82 to move. The refraction spring 85 presses the refraction member 82 against the adjusting shaft 2, allowing the refraction member 82 to move with the adjusting shaft 2.

[0035] To further improve the stability of the movement of the splitting component 82 and ensure accuracy, the system also includes a guide seat 84, which is installed in the moving hole 811. The top of the conductive seat is provided with a guide groove 841, which is U-shaped. The splitting component 82 is movably inserted into the guide groove 841. The splitting screw 83 abuts against one side of the guide seat 84 and is positioned opposite to the guide groove 841. The splitting screw 83 presses the splitting component 82 through the guide seat 84.
