Description

Technical Field

[0001] The utility model relates to the technical field of wireless button boxes, in particular to a wireless button box for a floor scale which is easy to disassemble and assemble. Background Art

[0002] Weighbridges are also called truck scales. They are large scales set on the ground and are usually used to weigh the tonnage of a truck. They are the main weighing equipment used by factories, mines, and businesses for bulk cargo measurement. Weighbridges can be divided into I-beam weighbridges, T-beam weighbridges, L-beam steel weighbridges, U-beam weighbridges, channel steel weighbridges, and reinforced concrete weighbridges according to the scale structure. They can be divided into digital weighbridges and analog weighbridges according to the sensor type. The operation of the wireless button box is through wireless data interaction. The wireless button box can read and write data through wireless communication and can be operated remotely through buttons.

[0003] Most of the existing wireless button boxes are integrally formed. When the parts inside the button box are damaged and need to be replaced, the entire box body needs to be destroyed for replacement, which increases the cost and reduces the working efficiency.

[0004] For example, Chinese patent CN215683014U discloses a wireless button box for a floor scale that is easy to disassemble and assemble. The method comprises placing a rectangular block into a slot. When the rectangular block applies force to a first spring, the first spring is tightened accordingly, so that the rectangular block can be clamped in the slot to fix the panel. By pressing the clamping block downward, the second spring can be tightened. When the clamping block is forced to contact the protrusion, the slots on both sides of the clamping block are clamped with the clamping block, so that the upper box body and the lower box body can be fixed. When the internal parts need to be inspected, the upper box body is squeezed downward, and the clamping block is compressed to apply force to the third spring, and the third spring moves to both sides accordingly, so that the upper box body and the lower box body can be separated, which is very convenient.

[0005] However, the wireless button box does not have a protective device when it is idle, resulting in dust adhering to the button box, which affects the sensitivity and service life of the button.

[0006] For this reason, we urgently need to provide a wireless button box for a weighbridge that is easy to disassemble and assemble. Utility Model Content
