Tubular beam connecting joint

Abstract

The invention belongs to the technical field of tubular beam connectors, and discloses a tubular beam connecting joint which comprises a base, a plurality of end seats and a plurality of screws, the end seats are arranged at intervals and fixedly connected with the base, openings are formed in the end seats and divide the end seats into upper half parts and lower half parts, and threaded holes are formed in the upper half parts. The screws are in threaded connection with the threaded holes respectively, abut against the lower half parts and then continue to rotate so that the opening can be expanded. After the end seats of the tubular beam connecting joint are inserted into a tubular beam, the end seats are expanded by rotating the screws, so that the end seats and the tubular beam are fixed through interference fit, a plurality of tubular beams can be quickly connected, fixed or detached, the efficiency is high, the outer surfaces of the end seats are attached to the inner surface of the tubular beam, the connecting precision is high, and the strength is high.

Description

technical field [0001] The invention relates to the technical field of pipe beam joints, in particular to a pipe beam joint. Background technique [0002] The pipe beam has a simple structure and reliable strength. It is one of the commonly used materials in automobile manufacturing. During the manufacturing process of the car body structure, multiple pipe beams need to be connected. At present, the joints of multiple pipe beams are usually welded with carbon dioxide shielded welding. or, the pipe beam is inserted into a common connection joint and then fixed with screws, however, the welding method is time-consuming and laborious and cannot be disassembled and reassembled after being fixed; it is fixed with screws after being inserted into a common connection joint In this way, the fit gap between the connecting joint and the pipe beam is large, the precision is low and the strength is low. Contents of the invention [0003] The object of the present invention is to prov...
