Description

Technical Field

[0001] The utility model relates to the field of automobile scales, in particular to a lateral limiting structure of an automobile scale. Background Art

[0002] Truck scales, also known as floor scales, are large scales installed on the ground. They are usually used to weigh the tonnage of a truck's cargo. They are the main weighing equipment used by factories, mines, and businesses to measure bulk goods. When the goods enter the weighing platform, the weight of the goods causes the elastic body of the weighing sensor to deform elastically, causing the impedance of the strain gauge bridge attached to the elastic body to lose balance, and output an electrical signal proportional to the weight value. The output digital signal is processed by the amplifier, A / D converter, microprocessor and other electronic components inside the sensor, and then enters the weighing display instrument through a repeater to directly display the weight and other data.

[0003] In order to prevent the vehicle from going too far and not showing all the weight of the vehicle when using the existing vehicle scale, it is necessary to set limit frames on the left and right sides of the vehicle scale. However, the lateral limit frames used in the existing vehicle scale still have the following problems during use:

[0004] In order to avoid being hit by a car and causing secondary damage to the car, the existing limit frames used in the automobile scales usually adopt an integrated limit frame with stronger stability. However, if the integrated limit frame causes a car collision, the integrated limit frame needs to be replaced as a whole, and the replacement cost is high. In addition, the integrated limit frame is large in size and has great installation strength with the automobile scale. Therefore, it is necessary to involve a lateral limit structure of a automobile scale for use in the existing automobile scale field. Utility Model Content

[0007] The threaded sleeves are symmetrically fixedly equipped with sliding blocks, which are movably assembled with the traction chambers. The threaded sleeves are fixedly equipped with external threads, which are close to one end of the threaded sleeves and are located on one side of the limit rod.

[0008] The external threads on the threaded sleeve are all threadedly assembled with threaded caps, and the rotating cavity is movably assembled with a transmission screw, which is threadedly assembled with the threaded sleeve;

[0010] The bottom of the limit rod is fixedly equipped with a plurality of support rods, the support rods are fixedly equipped with mounting blocks, and the side threads of the mounting blocks and the vehicle scale body are equipped with fastening bolts.

[0011] Preferably, both ends of the vehicle scale body are fixedly equipped with slope support blocks.
