Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1-2, the utility model discloses an adjustable road height-limiting frame, which comprises a sleeve 40 and two sets of mounting components symmetrically arranged relative to the sleeve 40. The mounting assembly comprises a base 10 and a mounting frame 20, wherein the mounting frame 20 is positioned on the base 10, the mounting frame 20 is of a 7-shaped structure, and a sleeve 40 is arranged between the two mounting frames 20.

The downside of sleeve pipe 40 is provided with the spacing subassembly of elasticity, and the spacing subassembly of elasticity includes connecting piece 50, spring assembly 51, regulating part 52 and locating part 53, and connecting piece 50 is fixed to be set up in the downside of sleeve pipe 40, and regulating part 52 is located the downside of connecting piece 50, is provided with spring assembly 51 between connecting piece 50 and the regulating part 52, and the upper end and the connecting piece 50 of spring assembly 51 are fixed to be set up, and the lower extreme and the regulating part 52 of spring assembly 51 are fixed to be set up. The lower surface of the adjusting member 52 is an arc-shaped slope, and a sensor for detecting whether the vehicle collides with the adjusting member 52 is embedded in the adjusting member 52.

The utility model discloses a theory of operation is: when the driver blindly detects the height of the vehicle driven by the driver and breaks the limit of the overhead, the top of the vehicle is pressed against the adjusting piece 52, and the sensor on the adjusting piece 52 detects the foreign matter. The sensor is connected to an alarm device, which is prior art and will not be described in detail here. And the sensor detects that vehicles exceeding the standard height try to pass, so that the alarm is given, and the security guard or the traffic police can conveniently deal with the traffic alarm in time. However, since the movement of the vehicle has a certain inertia, when the vehicle travels forward against the adjuster 52, as shown in fig. 3, the lower surface of the adjuster 52 has an arc-shaped slope, the upper end of which is disposed toward the vehicle. When the vehicle is forced to run into the height limiting frame, the vehicle can be pressed to enable the adjusting piece 52 to move upwards, and the spring set 51 is shortened. Thus, damage to the height limiting frame by the vehicle can be reduced.

A limiting member 53 is further fixedly arranged on the lower side of the connecting member 50, the limiting member 53 is positioned between the connecting member 50 and the adjusting member 52, and the height of the limiting member 53 is shorter than the length of the spring set 51. The limiting member 53 may limit the movement of the adjusting member 52. When the adjusting member 52 moves upward, the adjusting member 52 moves upward to the position of the limiting member 53, and thus the spring assembly 51 is protected.

The stopper 53 has a plurality. The sensor is a pressure sensor. The sensor may be provided in plurality, and the plurality of sensors can detect whether or not a vehicle is forcibly driven in.
