Embodiment 1

[0031] refer to Figure 1-9 , a mobile speedometer, comprising a radar speedometer 3 and a support cylinder 1, the support cylinder 1 supports the radar speedometer 3 through a support plate 4, a base 9 is provided for sliding on the bottom side of the support cylinder 1, and a universal joint is connected to the bottom side of the base 9 The wheel 10 and the base 9 are slidably connected to the bottom side of the support cylinder 1 through the insertion rod 8. The support cylinder 1 is slidably connected with a sliding sleeve 12, and the sliding sleeve 12 is connected with a support leg 6; when the speedometer needs to be moved, the sliding sleeve 12 Moving upwards drives the supporting legs 6 to move upwards, leaving the ground, and pulling out the insertion rod 8 on the bottom side of the supporting cylinder 1 downwards, so that the base 9 moves downwards, and the universal wheels 10 touch the ground, so that it is easy to move and realize different road sections. For detec...

Embodiment 2

[0034] refer to Figure 1-9, a mobile speedometer, comprising a radar speedometer 3 and a support cylinder 1, the support cylinder 1 supports the radar speedometer 3 through a support plate 4, a base 9 is provided for sliding on the bottom side of the support cylinder 1, and a universal joint is connected to the bottom side of the base 9 The wheel 10 and the base 9 are slidably connected to the bottom side of the support cylinder 1 through the insertion rod 8. The support cylinder 1 is slidably connected with a sliding sleeve 12, and the sliding sleeve 12 is connected with a support leg 6; when the speedometer needs to be moved, the sliding sleeve 12 Moving upwards drives the supporting legs 6 to move upwards, leaving the ground, and pulling out the insertion rod 8 on the bottom side of the supporting cylinder 1 downwards, so that the base 9 moves downwards, and the universal wheels 10 touch the ground, so that it is easy to move and realize different road sections. For detect...

Embodiment 3

[0039] refer to Figure 1-9 , a mobile velocimeter, basically the same as Embodiment 2, furthermore, the lifting plate 26 is fixedly connected to the sliding sleeve 12 through the connecting block 25, and the supporting cylinder 1 is provided with a sliding port 2 matching the connecting block 25, The lifting plate 26 and the sliding sleeve 12 can be connected stably through the connecting block 25, and the sliding opening 2 provided by the support tube 1 ensures that the lifting plate 26 and the sliding sleeve 12 can slide up and down while being fixedly connected on the support tube 1;

[0040] A piston 41 is slidably connected in the pneumatic cylinder 15, and the piston 41 is fixedly connected with the pneumatic rod 14, and the air release valve 40 is connected to the pneumatic cylinder 15; by inflating the pneumatic cylinder 15, the piston 41 is pushed to move, thereby realizing the The movement of the pneumatic rod 14 facilitates the expansion of the supporting legs 6; ...

Abstract

The invention discloses a leg structure of a mobile speedometer, and belongs to the field of vehicles. The leg structure of the mobile speedometer includes a support leg, the support leg is slidably coupled to a support cylinder through a sliding sleeve, and the support leg is rotatably coupled to the sliding sleeve; a pneumatic cylinder is fixedly connected to the bottom side of the sliding sleeve through a connecting rod; a pneumatic rod is connected to the pneumatic cylinder; the pneumatic rod is connected to the support leg; an inflator is fixedly connected to the support cylinder; and theexhaust end of the inflator is connected with the pneumatic cylinder through a connecting pipe. The support leg supports the radar speedometer for measuring speed, thereby ensuring stability; the support leg is stably placed on the ground, and when the support leg is folded, the support leg is rotated and reset for storage, the occupied space is reduced, movement is facilitated, and detection ofdifferent road sections is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an outrigger structure of a mobile speedometer. Background technique [0002] The main principle of the radar speedometer is the Doppler effect, that is, when the target approaches the radar antenna, the frequency of the reflected signal will be higher than the frequency of the transmitter; conversely, when the target moves away from the antenna, the frequency of the reflected signal will be lower than the frequency of the transmitter ;The radar speedometer emits electromagnetic waves, which will be reflected back when it touches an object; when the touched object has a displacement movement towards or away from it, there is a frequency difference between the electromagnetic wave emitted by the speedometer and the reflected electromagnetic wave, and through this frequency difference So as to obtain the speed of the object's movement and realize the purpose of speed measurement; ...
