[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The utility model digs a foundation pit in the ground in advance, casts a reinforced concrete base in the foundation pit, casts connecting platforms on both sides of the weighing pit reserved inside the reinforced concrete base, and installs a weighing platform in the weighing pit. The weighing platform is connected to the weighing sensor through L-shaped connecting legs on both sides of the bottom for support and load-bearing. The surface of the connecting platform is paved with rubber pads, and the top surface of the reinforced concrete base is paved with protective steel plates, which are flush with the ground. When the vehicle is weighed, it does not need to climb a slope and can be driven smoothly to the surface of the weighing platform. If the vehicle brakes and drives the weighing platform to shake due to inertia, it will drive the mounting frames at both ends of the bottom of the weighing platform, thereby squeezing and driving the connecting arm one, and the connecting arm one pushes the connecting arm two and squeezes and pulls through the spring two therebetween, thereby buffering the weighing platform. At the same time, the rubber pads laid on the surface of the connecting platform can avoid hard contact between the weighing platform and the connecting platform, and play a certain anti-collision function.

[0015] 2. In the utility model, when a vehicle is weighed on the surface of a weighing platform, the weighing platform will squeeze the bottom weighing sensor to measure the load-bearing data while squeezing the connecting rod two through the mounting plates and the movable shaft on both sides. The connecting rod two reduces the load-bearing of the weighing sensor on the weighing platform through the squeezing buffer between the movable sleeve rod and the spring one. Through the program that has been experimentally measured and edited in advance, while the buffer device assists in buffering the load-bearing and pressure resistance of the weighing sensor, it does not affect the weighing data measured by the weighing sensor. When the weighing platform is not working, the buffer device can reduce the pressure of the weighing platform's own weight on the weighing sensor, thereby increasing the service life of the device.
