Rapidly fixable road radar speed measuring device

Abstract

The invention discloses a rapidly fixable road radar speed measuring device including a radar speedometer. A push rod motor is arranged at the upper end of the radar speedometer. A handle is arrangedon the side of the push rod motor. A battery and an electric push rod are arranged inside the handle. A control switch 1 is disposed at one side of the handle. A mounting block is disposed at one endof the handle. A control switch 2 is disposed at the mounting block. An organic cylinder is disposed at the side of the mounting block. An electric hydraulic push rod 1, an electric cylinder and a stepping motor are disposed in the organic cylinder. An electric hydraulic push rod 2 is arranged on the side of the electric cylinder. The rapidly fixable road radar speed measuring device can rapidly fixes the radar speedometer on a vertical bar or a horizontal bar without the supporting and fixing of a bracket, the radar speedometer is easy to install and uninstall, the trouble of carrying the bracket is prevented, time and effort are saved, and The rapidly fixable road radar speed measuring device has good practicality.

Description

technical field [0001] The invention relates to the field of radar speed measurement, in particular to a rapidly fixed road radar speed measurement device. Background technique [0002] The speed radar mainly uses the Doppler effect principle: 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 transmission probability. In this way, the relative speed between the target and the radar can be calculated by changing the value of the frequency. Therefore, radar speedometers are widely used in industries such as police overspeed testing. [0003] However, the vast majority of radar speedometers currently on the market still have the following problems in actual use: [0004] In actual use, it is generally necessary to place a bracket at the lower end of the radar speedometer, a...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a road radar speed measuring device that can be quickly fixed in order to solve the above problems, so as to solve the problem that the traditional radar speed measuring instrument in the prior art needs to be installed on a bracket to perform road speed measuring operations normally, and the installation is troublesome. Moreover, the bracket is inconvenient to carry, and the practicability is not strong.
