Kind Code:
A1
Abstract:
Disclosed is a welding backing assembly, comprising a plurality of backings (1), wherein the plurality of backings (1) are integrally connected by means of a connection structure; each backing (1) comprises a first end portion and a second end portion arranged at two ends thereof in the length direction; the first end portion and the second end portion are respectively provided with a protrusion (3) and a groove (4) snap-fitted with each other; the connection structure comprises connection members arranged at lower surfaces of the backings (1) and used for connecting two adjacent backings (1); and the two adjacent backings can rotate relatively around a position where the upper surfaces thereof are in contact with each other. According to the welding backing assembly, every two adjacent backings are provided with the protrusions and the grooves, so as to achieve a positioning function for the connection of the backings, thereby making the connection of the backings more convenient; every two adjacent backings can rotate relatively around the position where the upper surfaces thereof are in contact with each other, such that the fitting between the backings and welding curved surfaces can be achieved; and the arrangement of the connection members can achieve a fixing function for the connected backings and prevent the backings from falling off.
