Description

Technical Field

[0001] The invention relates to the technical field of logistics trolley processing, and in particular to a logistics trolley processing welding device. Background Art

[0002] Manual logistics trolleys are a tool widely used in logistics, warehousing, manufacturing and other industries to carry and transport goods, especially when the goods need to be moved within a smaller range, or when carrying items of moderate weight and small size. This type of trolley does not require electricity or other power sources, but relies on manpower to push or pull. The manual logistics trolley is mainly composed of a base plate and a pusher, both of which are mainly processed by welding.

[0003] At present, during the welding process of the manual logistics trolley, in order to ensure the stable connection between the push handle and the base plate during the welding process, it is usually necessary to limit the base plate and manually support the push handle. However, the stability of manual support is not high, and the effect of limiting clamping is limited; secondly, in order to ensure the tightness of the welding at the connection between the base plate and the push handle during the welding process, the connection between the two needs to be tightly fitted, but the pressure is limited through manual support and pressing, and a good tight connection effect cannot be achieved. During the welding process, the clamping will be loose, and then the stability of the welding between the push handle and the base plate cannot be ensured. The welding position of the push handle and the base plate will be offset, which is not conducive to improving the welding quality. Summary of the invention
