Technical Field
[0001] This utility model relates to the field of aiming scope technology, and in particular to an aiming scope adjustment component with a spiral rotation mechanism. Background Technology
[0002] In current technology, rifle scopes often require users to remember the number of clicks and rotation directions needed to return the elevation angle to zero from different settings under certain operating conditions. For example, in twilight, at night, or in a dark room in a building, or when the user has difficulty hearing or feeling the clicks, it's easy to forget what adjustments were needed to return to zero. Therefore, a new and improved rifle scope is needed, featuring an adjustment stop to prevent exceeding the preset amount when adjusting the elevation angle; visual and tactile indicators of the number of rotations; and a locking mechanism to ensure that the adjustment parts are not accidentally rotated. In this regard…
[0003] However, existing technologies still have shortcomings, such as the following:
[0004] The existing method of recording rotation counts relies solely on observing the adjustment wheel scale and manual counting, which has many shortcomings. On the one hand, the observation angle of the relative position of the adjustment wheel scale and the eccentric buoy is limited, making it easy to produce reading deviations in poor lighting or at special operating angles. On the other hand, during long-term continuous operation, manual counting is prone to omissions, and key transmission components such as the splined dial lack visual feedback on the number of rotations. Operators cannot directly obtain rotation data through structural linkages, leading to frequent errors in rotation count recording and affecting the accuracy and consistency of aiming and adjustment. Utility Model Content

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1-8 As shown, the scope adjustment component with a helical rotation mechanism includes a spline screw 13. An adjustment seat 5 is fixedly sleeved on the outer wall of the spline screw 13, allowing the adjustment seat 5 to rotate the spline screw 13 while remaining stationary. A spline dial 16 engages with the top outer wall of the spline screw 13, facilitating its rotation. A geared piston 11 engages with the inner side of the top of the spline dial 16, driving its rotation. A locking disc 12 is engaged on the top of the outer wall of the spline dial 16, inside the geared piston 11, to limit its position. The locking disc 12 is threaded onto the spline dial. The inner wall of the geared piston has two annular grooves. When the adjustment handwheel is pulled, the geared piston moves up and down, causing the rubber ring 3 to disengage from one groove and enter the other. The rubber ring 3 and the two annular grooves provide a tactile feedback when pulling the adjustment wheel.
[0028] The outer wall of the adjustment seat 5 is engaged with the adjustment handwheel 2, so that the adjustment handwheel 2 cannot be rotated without being pulled. A marking ring 8 is installed on the inner side of the bottom of the adjustment handwheel 2. A dial pressure ring 4 is inserted into the outer wall of the top of the adjustment seat 5. The dial pressure ring 4 and the adjustment seat 5 are limited together by a pin. The outer wall of the inner side of the dial pressure ring 4 is engaged with a limiting cam 7, so that the limiting cam 7 cannot be rotated and is limited. A limiting cam pressure ring 6 is installed at the bottom of the limiting cam 7 to limit the up and down swing direction of the cam. An eccentric float 1 is connected to the top of the limiting cam 7 and slides inside the adjustment handwheel 2. When the adjustment handwheel 2 is rotated, the bottom of the eccentric float 1 is driven to rotate and slide inside the limiting cam 7.
[0029] It should be noted that in this embodiment, the operator pulls the adjustment handwheel 2 to disengage it from the teeth of the adjustment seat 5, so that the outer wall of the adjustment seat 5 does not engage with the adjustment handwheel 2. Only then can the adjustment handwheel 2 be rotated. In this way, the adjustment handwheel 2 can rotate. During the rotation of the spline dial 16, the spline screw 13 can be driven to move through the tooth engagement. The spline screw 13 is threadedly engaged with the adjustment seat 5, which allows the spline screw 13 to move up and down around the central threaded hole of the adjustment seat 5.
[0030] The mounting groove 25 on the top of the adjustment handwheel 2 is used to limit the position of the eccentric float 1. The adjustment gear 24 is fixedly connected to the outer wall of the inner side of the adjustment handwheel 2. The outer wall of the adjustment gear 24 meshes with the outer wall of the adjustment seat 5. The adjustment seat 5 is fixedly sleeved on the outer wall of the spline screw 13, so that it drives the spline screw 13 to rotate. The top of the adjustment handwheel 2 is provided with a guide arrow 22 for easy reference when rotating the adjustment handwheel 2. The top of the outer wall of the adjustment handwheel 2 is fixedly connected with a rotation area 23 for manual rotation of the adjustment handwheel 2. The bottom of the outer wall of the adjustment handwheel 2 is provided with a mark 21 for reference to the number of rotations. The inner side of the outer wall of the rotation area 23 is threaded with a set screw 14 to limit the axial sliding of the parts.
[0031] It should be noted that in this embodiment, during the rotation of the adjustment handwheel 2, the presence of the edge hole in the adjustment handwheel 2 ensures that the eccentric float 1 can only rotate along the central axis of the edge hole. The limiting cam 7 remains stationary, so the eccentric float 1 slides along the groove of the limiting cam 7. The limiting cam 7's limiting groove 71 has a number of turns, and the two ends of the groove restrict the movement of the eccentric float. When the eccentric float is restricted and stationary, the adjustment handwheel is also restricted from rotating. When the eccentric float is restricted by the inner end face of the limiting cam, a zero-position stop is achieved, realizing rapid zeroing. When the adjustment handwheel 2 rotates one revolution, the eccentric float 1 will rotate by a corresponding angle.
[0032] Multiple pin slots 41 are provided on the outer wall of the top of the dial pressure ring 4, which facilitates the insertion of pins into the inner side, thereby fixing the pin slots 41 to the upper surface of the adjustment seat 5. A dial gear block 42 is fixedly connected to the inner side of the dial pressure ring 4. The outer wall of the dial gear block 42 cooperates with the limiting gear block 72 to limit the rotation of the limiting cam 7. An adjustment slot 53 is provided on the outer wall of the bottom of the adjustment seat 5 for the insertion of pins to limit the dial pressure ring 4. An adjustment transmission gear block 52 is installed on the inner side of the adjustment seat 5 for the insertion of positioning pins for positioning. The inner wall of the adjustment transmission gear block 52 has 100 teeth, and the outer wall of the adjustment handwheel has 100 engravings. The teeth and engravings are in a one-to-one correspondence. A positioning gear block 51 is fixedly connected to the top of the outer wall of the adjustment seat 5. An adjustment mounting slot 54 is provided on the inner side of the middle part of the adjustment seat 5. The mounting slot 54 is used to cooperate with the spline screw through the thread, so that the spline screw can move up and down during the rotation. Furthermore, during the rotation of the spline dial, the positioning pin 15 slides out from one tooth of the toothed block 52 and into another tooth, working with the spring to provide a gear feel and sound during rotation; it also serves as a positioning function.
[0033] It should be noted that in this embodiment, when installing the dial pressure ring 4 and the adjustment seat 5, the pin groove 41 is first aligned with the upper surface of the adjustment slot 53, and then the pin is inserted into it to assemble them. When the adjustment gear 24 is in the inner side of the outer wall of the positioning tooth block 51, the adjustment handwheel 2 cannot be rotated, thus playing an effective limiting role.
[0034] The top of the eccentric buoy 1 is marked with a circle number arrow 111 for indicating the circle number. The bottom of the eccentric buoy 1 is equipped with a slide rod 112 so that the slide rod 112 is located inside the limiting slide groove 71 for limiting sliding, and is simultaneously limited to rotation by the adjustment handwheel 2.
[0035] It should be noted that in this embodiment, there is a marker on the eccentric buoy 1. When the adjustment handwheel 2 is rotated one revolution, the marker on the eccentric buoy 1 will be aligned with the number 1 on the adjustment handwheel 2. When the adjustment handwheel 2 is rotated two revolutions, the marker on the eccentric buoy 1 will be aligned with the number 2 on the adjustment handwheel 2, and so on.
[0036] The bottom of the limiting cam 7 has a limiting groove 71 for limiting the slide rod 112. The bottom of the outer wall of the limiting cam 7 is fixedly connected to the limiting tooth block 72 for meshing with the pressure ring 4 of the dial. Since the limiting groove 71 of the limiting cam 7 has a number of turns, the two ends of the groove will restrict the movement of the eccentric float. When the eccentric float is restricted and does not move, the adjustment handwheel is also restricted and no longer rotates. When the eccentric float is restricted by the inner end face of the limiting cam, the zero position is stopped and the rapid zeroing is achieved.
[0037] It should be noted that in this embodiment, during the rotation of the adjustment handwheel 2, the eccentric float 1 can only rotate along the central axis of the edge hole. Therefore, the eccentric float 1 slides along the groove of the limiting cam 7, and the eccentric float 1 will rotate by a corresponding angle when the adjustment handwheel 2 rotates one revolution.
[0038] The top of the spline dial 16 is fixedly connected to a connector 163 for convenient positioning and fixing of the locking disc 12. The spline bottom tooth block 161 is fixedly connected to the inner side of the bottom of the spline dial 16 for meshing with the outer wall of the spline screw 13. The inner side of the top of the spline dial 16 is fixedly connected to a tooth block 162 for cooperating with the gear piston 11. By rotating the gear piston 11, the spline dial 16 is driven to rotate, thereby driving the spline screw 13. A sealing groove 164 is opened at the bottom of the outer wall of the spline dial 16 for the rubber ring 3 to be fitted inside, improving the internal tightness. A return spring 165 is installed on the inner side of the outer wall of the spline dial 16 for pushing the positioning pin 15 to be inserted into the inner side of the adjustment transmission tooth block 52. The positioning pin 15 installed at one end of the return spring 165 and on the inner side of the outer wall of the spline dial 16, in conjunction with the spring, provides the gear feel and sound during rotation.
[0039] It should be noted that, in this embodiment, during the rotation of the adjustment handwheel 2, the spline dial 16 can be driven to move through the gear engagement. During the rotation of the spline dial 16, the spline screw 13 can be driven to move through the gear engagement.
[0040] The working principle of this utility model is as follows: The operator pulls the adjustment handwheel 2 to disengage the adjustment handwheel 2 from the teeth of the adjustment seat 5, so that the outer wall of the adjustment seat 5 does not engage with the adjustment handwheel 2. Only then can the adjustment handwheel 2 be rotated, so that the adjustment handwheel 2 can rotate.
[0041] During the rotation of the adjustment handwheel 2, the spline dial 16 can be driven to move through the gear engagement.
[0042] During rotation, the spline dial 16 can drive the spline screw 13 to move through gear engagement.
[0043] The spline screw 13 and the adjusting seat 5 are threaded together, allowing the spline screw 13 to move up and down around the central threaded hole of the adjusting seat 5.
[0044] In this case, during the rotation of the adjustment handwheel 2, the presence of the edge hole in the adjustment handwheel 2 ensures that the eccentric float 1 can only rotate along the central axis of the edge hole. The limiting cam 7 remains stationary, so the eccentric float 1 slides along the groove of the limiting cam 7. The limiting cam 7's limiting groove 71 has a number of turns, and the two ends of the groove restrict the movement of the eccentric float. When the eccentric float is restricted and stationary, the adjustment handwheel is also restricted from rotating. When the eccentric float is restricted by the inner end face of the limiting cam, a zero-position stop is achieved, realizing rapid zeroing. When the adjustment handwheel 2 is turned one revolution, the eccentric buoy 1 will rotate by a corresponding angle. When the adjustment handwheel 2 is turned two revolutions, the eccentric buoy 1 will rotate by a corresponding angle, and so on. There is a mark on the eccentric buoy 1. When the adjustment handwheel 2 is turned one revolution, the mark on the eccentric buoy 1 will align with the number 1 on the adjustment handwheel 2. When the adjustment handwheel 2 is turned two revolutions, the mark on the eccentric buoy 1 will align with the number 2 on the adjustment handwheel 2, and so on.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
