Description
Technical Field
[0001] This application relates to the field of sights, and more particularly to a sight with a limiting device. Background Technology
[0002] The primary function of a sight is to assist users in accurately observing and measuring targets. To improve aiming accuracy, the sight needs frequent calibration. During calibration, the sight is corrected by rotating the adjusting mount within it. Existing sights have a limiting structure in the adjusting mount to restrict its rotation; however, because this limiting structure itself occupies a certain length, the rotation angle of the adjusting mount is limited. To address the aforementioned issues, the inventor provides a sight with a limiting device. Utility Model Content
[0003] In order to limit the rotation of the adjusting seat in the sight, this application provides a sight with a limiting device.
[0004] The aiming device with a limiting device provided in this application adopts the following technical solution:
[0005] A sight with a limiting device includes an adjusting base, the adjusting base including an adjusting base, a fixing ring mounted on the top surface of the adjusting base, a fixing seat mounted on the top surface of the fixing ring, a rotating ring rotatably mounted on the top surface of the adjusting base and located on the inner edge of the fixing seat, and a limiting mechanism for limiting the rotation of the rotating ring; the limiting mechanism includes a limiting member mounted on the rotating ring and an abutment block arranged on the fixing seat and cooperating with the limiting member, the fixing seat having a sliding groove for circumferential sliding of the abutment block, and the rotation axis of the limiting member coinciding with the rotation axis of the abutment block.
[0006] By adopting the above technical solution, the aiming device is calibrated through the adjustment seat. During the calibration process, the rotating ring rotates, thereby driving the circumferential rotation of the limiting component. When the limiting component abuts against the abutting block, the rotating ring stops rotating, thereby limiting the circumferential rotation of the rotating ring. The setting of the sliding groove maximizes the circumferential rotation angle of the limiting component and reduces the influence of the space occupied by the limiting mechanism itself on the rotation angle of the adjustment seat.
[0007] Optionally, the limiting component includes a mounting plate fixed to the top surface of the rotating ring and a limiting protrusion arranged on the side of the mounting plate facing away from the adjusting base. The mounting plate is provided with a plurality of mounting through holes spaced apart circumferentially, and the mounting plate is fixed to the rotating ring by screws.
[0008] By adopting the above technical solution, the structure of the limiting component is disclosed. The mounting plate enables the limiting component to be fixed on the rotating ring, allowing the limiting component to rotate circumferentially synchronously with the rotating ring. The limiting protrusion facilitates abutment and engagement with the abutment block, thereby limiting the rotation of the rotating ring.
[0009] Optionally, the limiting protrusion is further provided with abutment joints on both sides, and the abutment joints are arranged parallel to each other above the mounting plate.
[0010] By adopting the above technical solution, the setting of the abutment joint helps to reduce the probability of damage to the limiting protrusion ring during use and ensures that the limiting function of the limiting component is performed normally.
[0011] Optionally, the adjusting base has a mounting ring portion, the bottom surface of the rotating ring has a contact surface that fits against the top surface of the adjusting base, and the rotating ring has a limiting protrusion extending toward the adjusting base and abutting against the inner wall of the mounting ring portion along the inner edge of the contact surface.
[0012] By adopting the above technical solution, the design of the contact surface and the limiting protrusion ring helps to reduce the probability of the rotating ring coming off the adjustment base, ensuring that the aiming device can be calibrated normally during the adjustment base calibration process.
[0013] Optionally, the abutting block has a sliding portion that is slidably installed in the sliding groove and an abutting portion that protrudes toward the rotating ring and cooperates with the limiting member, wherein the connection between the abutting portion and the sliding portion has an arc angle.
[0014] By adopting the above technical solution, the structure of the abutment block is disclosed. The setting of the arc angle at the connection between the sliding part and the abutment part helps to improve the structural strength of the abutment block, reduce the probability of the abutment block breaking during use, and ensure that the cooperation between the limiting part and the abutment block can be carried out normally.
[0015] Optionally, the bottom surface of the sliding groove is provided with multiple spaced first mounting grooves.
[0016] By adopting the above technical solution, setting a first mounting groove on the bottom surface of the sliding groove helps to reduce the contact area between the abutment block and the bottom surface of the sliding groove, reduce the frictional resistance of the abutment block during the sliding process, and help the limiting member push the abutment block to rotate circumferentially in the sliding groove.
[0017] Optionally, one end of the abutment block facing away from the abutment portion is attached to the sliding groove, and the fixing seat has a sliding portion attached to the abutment block at the inner edge of the sliding groove and a limiting ring portion for restricting the abutment block from dislodging from the sliding groove.
[0018] By adopting the above technical solution, the setting of the limiting ring helps to confine the abutment block within the sliding groove, reducing the probability of the abutment block coming out of the sliding groove and ensuring a stable fit between the limiting component and the abutment block.
[0019] Optionally, the top surface of the limiting ring abuts against the bottom surface of the abutting portion of the abutting block.
[0020] By adopting the above technical solution, the top surface of the limiting ring abuts against the bottom surface of the abutting part of the abutting block, which helps to provide support for the abutting part of the abutting block and reduces the probability of the abutting block breaking.
[0021] Optionally, when the abutment block is arranged in the sliding groove, the top surface of the abutment block is flush with the top surface of the fixing seat, and the top surface of the fixing seat is also provided with a pressing plate for limiting the abutment block, and the pressing plate is fixed to the top surface of the fixing seat by screws.
[0022] By adopting the above technical solution, the setting of the pressing plate helps to limit the probability of the abutment block coming out of the sliding groove during rotation, ensuring the normal implementation of the limit mechanism function.
[0023] Optionally, the pressing plate has multiple spaced second mounting grooves on the side facing the abutment block.
[0024] By adopting the above technical solution, the setting of the second mounting groove on the pressing plate helps to reduce the contact area between the top surface of the abutment block and the bottom surface of the pressing plate, thereby reducing the frictional resistance of the abutment block during the sliding process and facilitating the circumferential sliding of the abutment block in the sliding groove.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. A sight with a limiting device, wherein during the calibration process of the sight, the rotating ring on the adjusting seat rotates, thereby driving the upper limiting component of the rotating ring to rotate synchronously. When the limiting component pushes the abutting block to abut against the sliding groove, the rotating ring stops rotating. The sliding groove is designed to maximize the circumferential rotation angle of the limiting component and reduce the influence of the space occupied by the limiting mechanism itself on the rotation angle of the adjusting seat.
[0027] 2. By setting abutment joints at both ends of the limiting protrusion, the probability of the limiting protrusion breaking during use is reduced, ensuring the normal implementation of the limiting function of the limiting mechanism;
[0028] 3. The first mounting groove on the bottom surface of the sliding groove and the second mounting groove on the bottom surface of the pressing plate reduce the contact area between the abutment block and the sliding groove and the pressing plate, thereby helping the abutment block to slide smoothly in the sliding groove.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0037] This application discloses a sight with a limiting device. (Refer to...) Figure 1 and Figure 2 A sight with a limiting device includes an adjustment base 1 and a mounting bracket 2 for mounting the adjustment base 1. The adjustment base 1 includes an adjustment base 11, a fixing ring 12 mounted on the top surface of the adjustment base 11, a rotating ring 13 rotatably mounted on the top surface of the adjustment base 11 and located on the inner edge of the fixing ring 12, and a limiting mechanism 3 for limiting the rotation of the rotating ring 13.
[0038] Reference Figure 2 and Figure 3The limiting mechanism 3 includes a limiting member 31 mounted on the top surface of the rotating ring 13 and an abutting block 32 for abutting against the limiting member 31. The rotation axis of the limiting member 31 coincides with the rotation axis of the abutting block 32. The limiting member 31 includes a mounting plate 311 fixed to the top surface of the rotating ring 13 and a limiting protrusion 312 arranged on the side of the mounting plate 311 facing away from the adjusting base 11. The connection between the mounting plate 311 and the limiting protrusion 312 forms an arc angle. The mounting plate 311 has multiple mounting through holes spaced apart circumferentially, and is fixed to the rotating ring 13 by screws. To reduce the probability of damage to the limiting protrusion 312 during use, abutting joints 313 are also provided on both sides of the limiting protrusion 312, and the two abutting joints 313 are arranged parallel to each other above the mounting plate 311. In this embodiment, the limiting protrusion 312 is located at the center of the top surface of the mounting plate 311.
[0039] Reference Figure 4 The adjusting base 11 has a mounting ring portion 111, and the rotating ring 13 has a contact surface 131 that fits against the top surface of the adjusting base 11. In order to reduce the probability of the rotating ring 13 coming off the adjusting base 11, the rotating ring 13 has a limiting protrusion 132 at the inner edge of the contact surface 131 that extends toward the adjusting base 11 and abuts against the inner wall of the mounting ring portion 111 of the adjusting base 11.
[0040] Reference Figure 2 and Figure 5 A fixing seat 14 is mounted on the fixing ring 12, and the fixing seat 14 is fixed to the top surface of the fixing ring 12 by screws. The fixing seat 14 has a sliding groove 141 in the inner circumference for the circumferential sliding of the abutment block 32. The setting of the sliding groove 141 maximizes the circumferential rotation angle of the limiting member 31. The abutment block 32 has a sliding part 321 that is slidably installed in the sliding groove 141 and an abutment part 322 that is connected to the sliding part 321 and protrudes toward the rotating ring 13. When the rotating ring 13 rotates and drives the limiting member 31 to rotate synchronously, the abutment part 313 on the limiting protrusion abuts against the abutment part 322 of the abutment block 32. The abutment blocks 32 are arranged symmetrically, with the abutment portion 322 positioned at the center of the sliding portion 321 facing the fixed seat 14. This helps reduce the probability of the abutment portion 322 of the abutment block 32 impacting the fixed seat 14 and causing damage when the limiting member 31 pushes the abutment block 32 to slide. The connection between the abutment portion 322 and the sliding portion 321 has a rounded corner, which helps improve the connection strength of the abutment block 32 and reduces the probability of the abutment block 32 breaking when the limiting protrusion 312 engages with the abutment portion 322 of the abutment block 32. In this embodiment, the maximum circumferential rotation angle of the limiting member 31 is 360°, that is, the rotation range of the limiting member 31 is -180° to 180°.
[0041] Reference Figure 5When the abutment block 32 is arranged in the sliding groove 141, the end of the sliding portion 321 of the abutment block 32 facing away from the abutment portion 322 is attached to the end face of the sliding groove 141. In order to radially limit the abutment block 32, the fixing seat 14 has a limiting ring portion 142 at the inner edge of the sliding groove 141, which is attached to the side of the sliding portion 321 of the abutment block 32 facing the abutment portion 322, thereby reducing the probability of the abutment block 32 falling out of the sliding groove 141. The top surface of the limiting ring portion 142 abuts against the top surface of the abutment portion 322 of the abutment block 32, thereby effectively reducing the probability of the abutment block 32 breaking during use.
[0042] Reference Figure 5 and Figure 6 To facilitate the circumferential sliding of the abutment block 32 in the sliding groove 141, the bottom surface of the sliding groove 141 is provided with multiple spaced first mounting grooves 1411, thereby reducing the contact area between the bottom surface of the abutment block 32 and the sliding groove 141 and reducing the resistance of the abutment block 32 during the sliding process. When the abutment block 32 is arranged in the sliding groove 141, the top surface of the abutment block 32 is flush with the top surface of the fixing seat 14. In order to reduce the probability of the abutment block 32 falling out of the sliding groove 141 during the sliding process, the top surface of the fixing seat 14 is also provided with a pressing plate 15 for confining the abutment block 32 in the sliding groove 141. The pressing plate 15 has a pressing part 151 that covers the top opening of the sliding groove 141 and a connecting part 152 that connects the two sides of the main body of the pressing plate 15. The connecting part 152 of the pressing plate 15 has multiple mounting through holes. The pressing plate 15 is fixed to the top surface of the fixing seat 14 by screws. To facilitate the sliding of the abutment block 32, the pressing part 151 of the pressing plate 15 has multiple spaced second mounting grooves 1511 circumferentially arranged on the side facing the abutment block 32, thereby reducing the contact area between the abutment block 32 and the pressing plate 15.
[0043] The implementation principle of a sight with a limiting device in this application embodiment is as follows: During the calibration process of the sight, the rotation of the rotating ring 13 drives the rotation of the limiting member 31 installed on the top surface of the rotating ring 13. When the limiting member 31 abuts against the abutting block 32 and pushes the sliding part 321 of the abutting block 32 to abut against the sliding groove 141, the rotating ring 13 stops rotating, thereby limiting the circumferential rotation of the rotating ring 13. The setting of the sliding groove 141 maximizes the circumferential rotation angle of the limiting member 31 and reduces the influence of the space occupied by the limiting mechanism itself on the rotation angle of the adjusting seat.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
