It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-Figure 3 As shown, a field calibration device for motor vehicle overspeed monitoring equipment comprises an overall structure 1 and an auxiliary structure 2, wherein the auxiliary structure 2 is located at both sides of the top of the overall structure 1; the overall structure 1 comprises a bottom plate 101, and cylinders 110 are fixedly connected at front and rear positions on both sides of the bottom of the bottom plate 101, a damper 111 is fixedly installed at the inner top center of the cylinder 110, a spring 112 is sleeved on the outer surface of the damper 111, and a universal wheel 113 is fixedly connected to the extended end of the damper 111, a first electric telescopic rod 102 is fixedly installed on both sides of the top of the bottom plate 101, and a movable plate 103 is fixedly connected to the extended end of the first electric telescopic rod 102, a placement groove 106 is opened at the inner bottom center of the movable plate 103, a calibration component body 109 is slidably connected at the inner bottom center of the placement groove 106, and a bolt 105 is threadedly penetrated at the center of the front and rear outer surfaces of the movable plate 103.

[0022] The effect achieved by the entire embodiment 1 is that the spring 112 and the damper 111 cooperate with each other to reduce the vibration force, so that the effect of buffering and vibration reduction can be achieved, so that the overall shock absorption effect can be improved. When the user tightens the bolt 105, the clamping plate 107 can limit the calibration component body 109 more effectively, ensuring that the calibration component body 109 can always be located inside the placement groove 106. The setting of the first electric telescopic rod 102 can adjust the height of the movable plate 103, so the calibration component body 109 in the movable plate 103 will also be driven together, thereby achieving the height of the calibration component body 109 can also be adjusted for subsequent use.

[0023] Embodiment 2, as Figure 1-Figure 3 As shown, one end of the spring 112 is fixedly connected to the outer surface of the damper 111, and the other end of the spring 112 is fixedly connected to the top surface of the universal wheel 113. The outer surface of the universal wheel 113 is slidably connected to the inner surface wall of the cylinder 110. The outer surface of the bolt 105 is threadedly connected with a clamping plate 107. The outer surface of the clamping plate 107 is slidably connected to the front and rear outer surfaces of the calibration component body 109. The top center of the calibration component body 109 is slidably connected with the housing 104. The outer surface of the housing 104 is provided with positioning pins 106 on both sides. 08. A circular hole 114 is provided on the outer surface of the housing 104 at the position of the positioning pin 108. The inner wall of the circular hole 114 is slidably connected to the outer surface of the positioning pin 108. The bottom end surface of the positioning pin 108 passes through the surface of the movable plate 103. The auxiliary structure 2 includes a fixed block 201. A second electric telescopic rod 202 is fixedly installed at the inner top center of the fixed block 201. The protruding end of the second electric telescopic rod 202 is fixedly connected to an anti-slip pad 203. The outer surface of the fixed block 201 is fixedly connected to the outer surfaces of both sides of the bottom plate 101.

[0024] The effect achieved by the entire embodiment 2 is that the setting of the clamping plate 107 can realize the limiting and fixing operation of the calibration component body 109, the setting of the positioning pin 108 can realize the limiting of the shell 104, so that the shell 104 can always be stably located above the calibration component body 109, so that it can be normally shielded later, and the setting of the second electric telescopic rod 202 and the anti-slip pad 203 can improve the overall stability and ensure that the calibration component body 109 can be stable during operation.

[0025] Working principle: In the subsequent movement process, if a bumpy road surface is encountered, the damper 111 and the spring 112 will first feel the vibration force. Then, by utilizing the elasticity of the spring 112 and the characteristics of the damper 111 itself, the vibration force can be reduced, thereby achieving the effect of buffering and vibration reduction, so that the calibration component body 109 will not be affected by the vibration force, thereby increasing the service life of the calibration component body 109. If the calibration component body 109 needs to be disassembled later, the user first pulls out the positioning pin 108. After pulling it out, the shell 104 can be detachable. Then the user manually tightens the bolt 105. When the bolt 105 is tightened, the splint 107 will be moved at the same time, so that the splint 107 can be separated from the calibration component body 109. After separation, the user can manually take out the calibration component body 109.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
