Description

Technical Field

[0001] This utility model belongs to the field of aiming scope technology, specifically relating to a multi-functional adjusting screw for aiming scopes. Background Technology

[0002] A scope is a tool used to adjust the front sight of a firearm or optical instrument. By adjusting the scope, the front sight can be aligned with the target, thereby improving accuracy. Properly adjusting the scope is crucial when firing or observing.

[0003] Most existing scope adjustment screws can only perform basic zeroing and adjustment functions, and their functionality is limited, unable to simultaneously satisfy functions such as locking and position memory. Depending on the usage requirements, the effective working range of the adjustment screw varies. For a specific gun and ammunition, after the gun is calibrated at a specific distance, that position is uniquely fixed. If position memory cannot be achieved, it will prolong the scope adjustment time and increase the complexity of operation. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a multi-functional adjusting screw for a scope. It fixes the long tapered pin by abutting the locking pin, so that the adjusting pin cannot move and thus achieves the locking function. Furthermore, through the cooperation between the limiting ring and the pressure ring, the adjusting pin is stopped at zero, which can effectively improve the adjustment efficiency.

[0005] A multi-functional adjusting screw for a scope includes a locking screw, an adjusting handwheel, a limiting ring, an adjusting screw, and an adjusting base. The adjusting handwheel is sleeved with the adjusting base, forming a cavity for installing the adjusting screw. One end of the adjusting screw is connected to the adjusting handwheel, and the other end is threaded to the adjusting base. A long tapered pin is disposed inside the adjusting screw and connected to a spring. The long tapered pin reciprocates due to the elasticity of the spring. A locking screw is mounted on the adjusting handwheel, and the adjusting screw has a receiving groove for insertion. Rotating the locking screw until it abuts against the long tapered pin locks the multi-functional adjusting screw. A limiting ring is sleeved on the adjusting screw, and a pressure ring is engaged between the adjusting base and the adjusting handwheel. Adjusting the position of the limiting ring until it contacts the pressure ring provides a zero-stop limit for the adjusting screw.

[0006] Preferably, one end of the long tapered pin is connected to a steel ball, and the other end is connected to a spring. The other end of the spring is connected to an adjusting pin. The steel ball is brought into contact with the inner wall of the adjusting seat by the elastic action of the spring. The inner wall of the adjusting seat is provided with straight teeth.

[0007] Preferably, an index ring is provided between the adjustment handwheel and the adjustment seat, the index ring is provided with scale lines, and the adjustment handwheel is provided with a "0" scale line.

[0008] Preferably, a sealing ring one is disposed between the locking pin and the adjusting pin, a sealing ring two is disposed between the adjusting pin and the adjusting handwheel, and a sealing ring three is disposed between the adjusting handwheel and the adjusting seat.

[0009] Preferably, the adjusting pin is also equipped with a short tapered pin inside. One end of the short tapered pin is connected to a steel ball, and the other end is connected to a spring. The other end of the spring is connected to the adjusting pin. The elasticity of the spring causes the steel ball to contact the inner wall of the adjusting seat.

[0010] Preferably, the adjustment handwheel is fitted with multiple ballistic rings, and each ballistic ring is provided with a ballistic marker.

[0011] Preferably, the adjustment mount is connected to the scope, and a shim is provided between the adjustment mount and the scope.

[0012] The beneficial effects of this utility model are: the scope uses a multi-functional adjusting screw, and rotating the adjustment handwheel drives the adjusting pin to rotate, so as to adjust the relative position of the adjusting pin and the adjustment seat. Through the cooperation of spring one, long tapered pin and steel ball one, the steel ball one contacts the straight teeth on the adjustment seat to produce a click, which makes it easy for the user to control the rotation angle of the adjustment handwheel.

[0013] The adjusting screw is fixed by abutting against the long tapered pin, thus preventing the adjusting screw from moving and achieving the locking function. This allows the user to lock the adjusting screw when needed, preventing the adjusting screw from shifting and affecting the use of the scope.

[0014] Furthermore, by making reasonable use of the space between the adjustment handwheel and the adjustment seat, and by utilizing the cooperation between the limit ring and the pressure ring, the adjustment pin is stopped at zero, so that the adjustment pin can only move upward and not downward when it is in this position, thus reducing the adjustment range of the adjustment pin and effectively improving the adjustment efficiency.

[0015] Furthermore, by setting multiple ballistic rings in conjunction with the indicator ring, and using the zeroing function in conjunction with the adjustment handwheel, a ballistic marking function is added to facilitate users in marking different ballistic data and improve user comfort.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, a multi-functional adjusting screw for a scope includes a locking screw 1, an adjusting handwheel 2, a limiting ring 3, an adjusting screw 4, and an adjusting base 5.

[0026] Specifically, the adjustment handwheel 2 is sleeved with the adjustment seat 5, forming a cavity for installing the adjustment pin 4. One end of the adjustment pin 4 is connected to the adjustment handwheel 2 via a locking screw 19, and the other end is threaded to the adjustment seat 5. Rotating the adjustment handwheel 2 causes the adjustment pin 4 to rotate, moving it up and down, thereby adjusting the relative position of the adjustment pin 4 and the adjustment seat 5. The adjustment seat 5 is connected to the scope, and a gasket 18 is disposed between the adjustment seat 5 and the scope. In this embodiment, the gasket 18 is made of rubber to improve waterproofing.

[0027] like Figure 1 As shown, the adjusting pin 4 is internally equipped with a horizontally arranged long tapered pin 7. One end of the long tapered pin 7 is connected to a steel ball 8, and the other end is connected to a spring 9. The other end of the spring 9 is connected to the adjusting pin 4. The steel ball 8 is made to contact the inner wall of the adjusting seat 5 by the elastic action of the spring 9.

[0028] In addition, such as Figure 5 As shown, the inner wall of the adjustment base 5 is provided with straight teeth 501. When the adjustment pin 4 rotates with the adjustment handwheel 2, it drives the steel ball 8 to contact the straight teeth 501 on the inner wall of the adjustment base 5, thereby producing a click-like feeling, which makes it easy for the user to control the rotation angle.

[0029] like Figure 1 , Figure 2 As shown, a locking pin 1 is installed on the adjustment handwheel 2, and a receiving groove for the locking pin 1 is provided on the adjustment pin 4. When the locking pin 1 is rotated and moved to abut against the long tapered pin 7, the long tapered pin 7 cannot move due to the pressure of the locking pin 1. At this time, the scope's multi-function adjustment screw is in the locked state. The locked state when the adjustment pin 4 is fully retracted is as follows: Figure 1 As shown, the locking state of adjusting pin 4 when it is pressed all the way down is as follows: Figure 2 As shown.

[0030] like Figure 3 As shown, a limit ring 3 is fitted onto the adjusting pin 4. The limit ring 3 is equipped with a locking screw 20 to fix its position. Adjusting the position of the limit ring 3 allows the adjusting pin 4 to have a zero-stop function. Specifically, as shown... Figure 3 As shown, a pressure ring 3 is engaged between the adjustment seat 5 and the adjustment handwheel 2. Adjust the position of the limit ring 3 so that it contacts the pressure ring 3. At this time, the adjusting pin 4 can only move upward and cannot move downward. This position is the zero stop position of the adjusting pin 4.

[0031] like Figure 3 As shown, an index ring 6 is provided between the adjustment handwheel 2 and the adjustment base 5. The index ring 6 has scale lines, and the adjustment handwheel 2 has a "0" scale line. To achieve the zeroing function, the locking screw 19 needs to be loosened to separate the adjustment handwheel 2 from the adjusting pin 4, and then the adjustment handwheel 2 is rotated to align its "0" scale with the corresponding scale line on the index ring 6.

[0032] In addition, such as Figure 3 As shown, the distance between the adjustment handwheel 2 and the bottom of the indicator ring 6 is H. During adjustment, this distance H will change, and the number of rotations of the adjustment handwheel 2 can be indicated according to the size of the distance H.

[0033] Furthermore, a sealing ring 15 is provided between the locking pin 1 and the adjusting pin 4, a sealing ring 16 is provided between the adjusting pin 4 and the adjusting handwheel 2, and a sealing ring 17 is provided between the adjusting handwheel 2 and the adjusting seat 5. The sealing rings improve the sealing between the components and achieve the waterproof function.

[0034] Working principle: This scope uses a multi-functional adjusting screw. In use, the adjusting handwheel 2 is separated from the adjusting pin 4 by tightening screw 19. Then, the adjusting handwheel 2 is rotated to zero, so that the "0" mark on the adjusting handwheel 2 is aligned with the mark on the index ring 6. Then, the adjusting handwheel 2 is connected to the adjusting pin 4 by tightening screw 19, so that the adjusting pin 4 rotates when the adjusting handwheel 2 is rotated, allowing the adjusting pin 4 to move up and down. When the adjusting pin 4 is rotated, steel ball 18 and steel ball 21 contact the straight tooth 501 in the adjusting seat 5 to generate a positioning feel.

[0035] Furthermore, when tightening the adjusting screw, tighten the locking pin 1 downwards until it abuts against the long pin 7. At this time, the long pin 7 is fixed in position by the pressure of the locking pin 1 and cannot rotate, thus easily achieving the locking function. Then, rotate the locking pin 1 to disengage it from the long pin 7, allowing the long pin 7 to rotate freely, thereby adjusting the adjusting screw from the locked state to the working state.

[0036] When the adjusting screw requires a zero-stop function, the locking pin 1 and adjusting handwheel 2 need to be removed using the locking screw 1. Then, the locking screw 2 is loosened, and the position of the limit ring 3 is adjusted until it contacts the pressure ring 13. The limit ring 3 is then fixed to the adjusting pin 4 using the locking screw 2, and the locking pin 1 and adjusting handwheel 2 are then reset. At this point, through the interaction between the limit ring 3 and the pressure ring 13, the adjusting pin 4 can only move upwards, achieving the zero-stop function.

[0037] Example 2

[0038] like Figure 1 , Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, except that: in this embodiment, a short tapered pin 10 is also configured inside the adjusting pin 4. One end of the short tapered pin 10 is connected to a steel ball 11, and the other end is connected to a spring 12. The other end of the spring 12 is connected to the adjusting pin 4, and the steel ball 11 contacts the inner wall of the adjusting seat 5 through the elastic action of the spring 12. Furthermore, in order to improve the stability of the rotation of the adjusting pin 4, the positions of the steel ball 8 and the steel ball 11 are opposite.

[0039] Example 3

[0040] like Figure 3 , Figure 6 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, except that: in this embodiment, multiple ballistic rings 14 are fitted onto the adjustment handwheel 2, and each ballistic ring 14 is provided with a ballistic marker 1401. The ballistic marker 1401 cooperates with the scale lines on the indicator ring 6 to achieve data marking of different ballistic trajectories. It should be noted that the ballistic ring 14 is made of rubber, and it has a certain amount of compression when fitted onto the adjustment handwheel 2 to ensure that it can rotate but will not loosen or shift under impact.
