Description

Technical Field

[0001] The utility model specifically relates to the field of traffic engineering, and in particular to a campus vehicle speed measuring device which is easy to assemble and disassemble. Background Art

[0002] Vehicle speed measurement determines whether the vehicle is speeding based on the speed at which the vehicle passes through parallel coils, and takes video evidence. The disadvantage of this detection method is that the construction of the induction coil buried in the ground is large, and the coil needs to be reburied once the road surface changes. In addition, the maintenance work for the coil is huge during the thawing period at high latitudes, the summer road surface at low latitudes, and places with poor road quality.

[0003] The vehicle speed measuring devices on campus are installed at a high position. During maintenance and disassembly, there is a certain risk due to the large flow of people on campus. In addition, the existing vehicle speed measuring devices are installed with fasteners such as screws, which makes installation, disassembly and maintenance more laborious.

[0004] For this reason, we propose a campus vehicle speed measuring device that is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0013] Preferably, the external threads of the two screw rods have opposite rotation directions.

[0014] Compared with the prior art, the beneficial effects of the utility model are:
