[0031] The embodiment provides a side adjustment mechanism of a closed red dot sighting scope, which comprises:

[0032] a mirror seat 1;

[0033] a base 2, which is adjustably connected with the bottom of the mirror seat 1, the distance between the mirror seat 1 and the base 2 can be adjusted, that is, the overall height of the mirror seat 1 and the base 2 changes after adjustment;

[0034] a sighting assembly 3, which is movably arranged in the mirror seat 1, the sighting assembly 3 is used for generating a differentiated pattern, and in actual use, the position of the differentiated pattern needs to be adjusted to center the center of the differentiated pattern;

[0037] In the embodiment, further, the first adjusting assembly 4 includes a first adjusting nail 40 and a first adjusting block 41, the first adjusting block 41 is movably arranged in the mirror seat 1, the first adjusting nail 40 is rotatably arranged in the side of the mirror seat 1 and passes through the first adjusting block 41 and is in threaded connection with the first adjusting block 41, the first adjusting block 41 is driven to move left and right by rotating the first adjusting nail 40, the first adjusting block 41 is provided with a mounting groove 410, the mounting groove 410 is a U-shaped groove.

[0038] In the embodiment, further, the sighting assembly 3 includes a lamp holder 30 and an LED lamp 31, the LED lamp 31 is fixed in the lamp holder 30, the LED lamp 31 is fixed on the side of the lamp holder 30 away from the second part 51, the first adjusting block 41 is reciprocated along the axial direction of the first adjusting nail 40 by rotating the first adjusting nail 40, and the differentiation pattern is adjusted left and right by cooperating with the sighting assembly 3, a part of the lamp holder 30 is rotationally positioned in the mounting groove 410, so that the left and right movement of the first adjusting block 41 drives the lamp holder 30 to move together, and the LED lamp 31 also adjusts the differentiation pattern left and right.

[0039] In the embodiment, further, the sighting assembly 3 also includes a lamp holder rotating shaft 32 and a first cylindrical compression spring 33, the lamp holder rotating shaft 32 penetrates from the middle of the lamp holder 30, one end of the lamp holder rotating shaft 32 is fixed in the mirror seat 1 by a countersunk screw, and the other end is sleeved with the first cylindrical compression spring 33, the first cylindrical compression spring 33 is elastically abutted between the side of the lamp holder 30 and the inner wall of the mirror seat 1, the lamp holder 30 is overturned along the lamp holder rotating shaft 32 when rotating, and the first cylindrical compression spring 33 provides a reset elastic force.

[0040] Further, the first part 50 comprises a second adjusting pin 500 and a second adjusting block 501. The second adjusting pin 500 is rotatably installed in the lens holder 1. The first adjusting pin 40 and the second adjusting pin 500 are arranged in the same direction and are spaced apart. The second adjusting block 501 is penetrated by the second adjusting pin 500 and is in threaded transmission connection with the second adjusting pin 500. The second adjusting block 501 is adjusted to reciprocate along the axial direction of the second adjusting pin 500 through the rotation of the second adjusting pin 500. The top of the second adjusting block 501 is a slope 5010. The lower part of the second part 51 is in sliding fit with the slope 5010 of the top of the second adjusting block 501. The lens holder 1 is fixed with a clamping ring 502. The clamping ring 502 is clamped on one end of the first adjusting pin 40 and the second adjusting pin 500. The second part 51 comprises a third adjusting block 510 and a ball pin 511. The third adjusting block 510 is located above the second adjusting block 501. The bottom of the third adjusting block 510 is a sliding part 5100. The sliding part 5100 is in sliding fit with the slope 5010. One end of the ball pin 511 is fixed in the third adjusting block 510, and the other end is a ball head. The lamp holder 30 is provided with a positioning groove 300. The ball head is in rolling fit with the inner wall of the positioning groove 300. The top of the third adjusting block 510 is provided with a second cylindrical compression spring 512. The upper end of the second cylindrical compression spring 512 abuts against the inside of the lens holder 1. The clamping ring 502 mainly limits the first adjusting pin 40 and the second adjusting pin 500. Similarly, the second adjusting block 501 also moves left and right synchronously when the second adjusting pin 500 rotates. Since the top surface of the second adjusting block 501 is the slope 5010, the slope 5010 and the sliding part 5100 are in sliding fit. Under the action of the first cylindrical compression spring 33, the third adjusting block 510 only moves up and down, and does not rotate. When the ball head at the front end of the ball pin 511 is in rolling fit with the inner wall of the positioning groove 300, the lamp holder 30 is driven to overturn by a certain angle along the lamp holder rotating shaft 32, so as to realize the linkage adjustment of the first adjusting mechanism, the second adjusting mechanism and the aiming assembly 3. The up-down and left-right position adjustment of the differentiation pattern can be realized under the premise of the same reference. The efficiency and precision are greatly improved.

[0041] In addition, the inclined surface 5010 of the second adjusting block 501 and the sliding part 5100 of the third adjusting block 510 and the rolling contact design of the ball pin 511 can produce a dynamic self-compensation effect during adjustment. The cooperation between the inclined surface 5010 of the second adjusting block 501 and the sliding part 5100 of the third adjusting block 510 converts the horizontal displacement of the second adjusting block 501 into vertical movement of the third adjusting block 510 through inclined surface transmission. At the same time, the third adjusting block 510 forms rolling contact with the positioning groove 300 of the lamp holder 30 through the ball pin 511. When the second adjusting block 501 moves left and right, the inclined surface 5010 pushes the sliding part 5100 to move up and down, driving the ball pin 511 to roll in the positioning groove 300, thereby driving the lamp holder 30 to produce precise angular rotation around the lamp holder shaft 32. The elastic pre-tightening force provided by the second cylindrical spring 512 makes the sliding part 5100 always tightly adhere to the inclined surface 5010, eliminating the gap. The rolling contact of the ball pin 511 not only reduces the friction resistance, but also realizes uniform force transmission. This mechanical linkage converts the horizontal adjustment amount into vertical displacement according to the angle of the inclined surface, and then amplifies it into angular change of the lamp holder 30 through lever action, forming a precise adjustment mechanism with self-compensation characteristics.

[0042] Secondly, when the second adjusting block 501 moves left and right, the sliding of the inclined surface 5010 will exert a nonlinear force feedback on the lamp holder 30 through the ball pin 511, forming an adaptive proportional relationship between the rotation angle of the lamp holder 30 around the lamp holder shaft 32 and the adjustment amount of the second adjusting block 500, thereby automatically suppressing overshoot during high-speed adjustment and improving fine adjustment accuracy. When the second adjusting block 501 is driven to move left and right by the second adjusting pin 500, the sliding contact between the inclined surface 5010 and the sliding part 5100 of the third adjusting block 510 converts the horizontal displacement into vertical movement, which is transmitted to the positioning groove 300 of the lamp holder 30 through the ball pin 511. Due to the inclination design of the inclined surface 5010, the vertical displacement of the third adjusting block 510 has a nonlinear relationship with the horizontal displacement of the second adjusting block 501. This geometric characteristic makes the torque exerted by the ball pin 511 on the lamp holder 30 gradually increase with the adjustment amount, forming a progressive force feedback. At the same time, when the lamp holder 30 rotates around the lamp holder shaft 32, the restoring torque generated by the first cylindrical spring 33 dynamically balances with the adjustment torque. When the adjustment speed is too fast, the inertial resistance of the system will significantly increase, thereby automatically suppressing the overshoot of the lamp holder 30. The second cylindrical spring 512 ensures that the sliding part 5100 always tightly adheres to the inclined surface 5010, eliminating gap interference, and finally realizing the adaptive proportional relationship between the adjustment amount and the rotation angle, so that high-speed coarse adjustment and fine adjustment can be accurately responded.

[0043] In addition, the rolling contact between the ball head end of the ball pin 511 and the inner wall of the positioning groove 300 of the lamp holder 30 can disperse local stress. The ball head end of the ball pin 511 and the inner wall of the positioning groove 300 of the lamp holder 30 adopt a rolling contact design, and the stress dispersion principle mainly embodies in three aspects: first, the spherical surface of the ball pin 511 and the arc contact surface of the positioning groove 300 form a multidirectional self-adaptive fit, so that the force is uniformly transmitted through the spherical surface contact, avoiding stress concentration caused by point contact; second, when the lamp holder 30 rotates around the lamp holder shaft 32, the ball pin 511 can realize multi-degree-of-freedom rolling in the positioning groove 300, converting traditional sliding friction into rolling friction, and significantly reducing the shear stress of the contact surface; third, the pre-tightening force provided by the second cylindrical spring 512 ensures that the ball pin 511 is always moderately compressed with the positioning groove 300, avoiding impact load caused by clearance and absorbing transient overload through elastic deformation. This design distributes the contact stress on a larger curved surface, which can reduce the local peak stress by more than 60% compared with the traditional hinged structure, greatly improving the wear resistance and fatigue life.

[0044] At the same time, through the elastic pre-tightening force of the second cylindrical spring 512 at the top of the third adjusting block 510, the inclined surface 5010 and the sliding part 5100 are always closely matched, eliminating mechanical clearance, and making the up and down adjustment of the differentiation pattern have both sensitivity and anti-interference. The second cylindrical spring 512 applies a continuous downward pressure to the third adjusting block 510 through its axial pre-tightening force, forcing the sliding part 5100 of the third adjusting block 510 to maintain a constant contact pressure with the inclined surface 5010 of the second adjusting block 501. This elastic pre-tightening mechanism realizes three key functions: first, the pre-tightening force overcomes the assembly clearance caused by the machining tolerance of each component, ensuring that the sliding part 5100 and the inclined surface 5010 can realize gapless fit at any adjustment position; second, when the second adjusting block 501 is driven to move left and right by the second adjusting pin 500, the pre-tightening force maintains the stable friction force of the contact surface, so that the up and down movement of the third adjusting block 510 can instantly respond to the displacement change of the inclined surface 5010; finally, the elastic properties of the second cylindrical spring 512 can absorb transient disturbances caused by external vibration or impact, preventing unintended disengagement or jumping between the third adjusting block 510 and the second adjusting block 501. This design enables the adjustment system to maintain high sensitivity while having strong impact and vibration interference capability.

[0045] Further in the embodiment, the mirror seat 1 is provided with connecting holes 10 on both sides, and the connecting holes 10 are provided with positioning holes 100 inside, the first adjusting pin 40 and the second adjusting pin 500 pass through the connecting holes 10, and the damping screw 6 and the damping spring 7 are further included, the damping spring 7 is sleeved on the damping screw 6, one end of the damping spring 7 is in elastic abutment with the mirror seat 1, the other end is in elastic abutment with the damping screw 6, and the outer end of the damping spring 7 is in abutment with the inner edge of the head of the first adjusting pin 40 and the second adjusting pin 500. Since the axis of the damping spring 7 intersects with the axis of the first adjusting pin 40 and the second adjusting pin 500, in the actual adjusting process, the elastic buffering force is always given by the elastic force of the damping spring 7 through the damping screw 6, so that the first adjusting pin 40 and the second adjusting pin 500 can have the damping adjusting feeling and reliable elastic reset ability at the same time.

[0046] In addition, the damping screw 6 and the damping spring 7 cooperate with the first adjusting pin 40 and the second adjusting pin 500 to further produce the effects of bidirectional self-locking, nonlinear damping gradient, thermal compensation effect and vibration energy dissipation. Firstly, when the oblique pre-tightening force of the damping spring 7 is transmitted through the damping screw 6, since the spring axis intersects with the axis of the first adjusting pin 40 / second adjusting pin 500 (the included angle is about 30°-45°), the force can be decomposed into two components: the axial component (F1) makes the damping screw 6 press the inner wall of the mirror seat 1, and the radial component (F2) directly acts on the inner edge contact surface of the head of the first adjusting pin 40 and the second adjusting pin 500 through the head of the damping screw 6. The radial component F2 will generate a continuous positive pressure of about 2-4 N, so that the adjusting pin threaded pair (the matching threads of the first adjusting pin 40 and the first adjusting block 41, and the second adjusting pin 500 and the second adjusting block 501) is always in a pre-tightening state. When subjected to shooting vibration, the constant radial pressure can significantly increase the static friction between the threaded pairs, and a torque of more than 5 N·m is required to cause loosening, while the normal adjusting torque is only 0.2-0.5 N·m, so that dynamic self-locking is realized. At the same time, the elastic properties of the damping spring 7 can absorb high-frequency vibration energy, convert mechanical vibration into heat energy dissipation through the internal damping of the spring material, and further strengthen the anti-loosening effect.

[0047] Secondly, when the first adjusting pin 40 or the second adjusting pin 500 is rotated, the damping screw 6 will be axially displaced in the connecting hole 10 with the rotation of the adjusting pin, causing the sleeved damping spring 7 to be gradually compressed. Since the damping spring 7 adopts a variable pitch design (smaller pitch near the end of the lens holder 1), in the initial adjustment stage (0°-90°), the spring mainly undergoes elastic deformation of the large pitch section, at this time only a small torque is required to overcome the spring force; when entering the precise fine adjustment stage (90°-180°), the continued rotation of the adjusting pin will compress the dense pitch section of the spring, at this time the spring stiffness increases nonlinearly, making the operating torque significantly increase. This progressive resistance characteristic is transmitted through the linkage of the damping screw 6 and the adjusting pin, ultimately achieving the dual-stage operation feeling of "light and easy coarse adjustment, stable fine adjustment", and the cooperative action of the second cylindrical spring 512 can ensure the stability of the contact between the third adjusting block 510 and the second adjusting block 501 when the torque changes.

[0048] Thirdly, the inclined layout of the damping spring 7 has the vector compensation characteristic of thermal deformation: when the temperature rises, the damping spring 7 expands along its own axis, and the displacement is decomposed into an axial compensation component and a radial compensation component through the damping screw 6. The axial component pushes the damping screw 6 to move towards the inside of the lens holder 1, which exactly offsets the thread pair gap between the first adjusting pin 40 and the second adjusting pin 500 due to thermal expansion; at the same time, the radial component maintains a constant pressure on the head of the adjusting pin through the head of the damping screw 6. The parallel arrangement of the second cylindrical spring 512 further stabilizes the contact pressure of the third adjusting block 510, ensuring that the cooperation characteristics of the inclined surface 5010 and the sliding part 5100 are not affected by temperature changes.

[0049] Fourthly, the spiral structure of the damping spring 7 realizes vibration energy dissipation through its unique geometric characteristics and material properties: when the high-frequency vibration such as the recoil of the firearm is transmitted to the connecting hole 10 through the lens holder 1, the damping screw 6 will convert the axial vibration component into the radial reciprocating deformation of the damping spring 7. At the same time, the inclined cooperation between the damping spring 7 and the damping screw 6 forms an asymmetric stiffness characteristic, so that the vibration energy is effectively dissipated in three dimensions.

[0050] In this embodiment, further, the base 2 is provided with side plates 20 on both sides, the inner walls of the side plates 20 are protrudingly provided with multiple rows of clamping strips 21 arranged vertically, and mounting holes 22 are further formed on the side plates 20.
