Abstract

The invention discloses a ceiling fixing fastener comprising a cylindrical fastener body (1), a buckling cover (11) is arranged on one side of the fastener body (1), an annular groove (12) is formed in the other side, and a limiting annular block (2), a first guide block (31) and a second guide block (32) are further arranged on the fastener body (1); a first open groove (131), a second open groove (132) and a third open groove (133) are formed in the fastener body (1), abutting blocks (3) are arranged between every two adjacent open grooves; a clamping jaw is arranged in a middle through holeof the fastener body (1), and a discharging connecting rod (4) is arranged at one end of the clamping jaw. According to the ceiling fixing fastener in the invention, the abutting blocks and the clamping jaw are arranged, so that the outer side and the inner side of the buckling body are in full contact connection with the corresponding positions of a connecting part, disassembly and assembly areconvenient, installation gaps are reduced, and the connection stability is strong.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a roof fixing fastener. Background technique [0002] At present, there are generally two connection methods between the ceiling and the columns, butt joint and lap joint. In the current car roof fixing technology, most of the butt joints and lap joints are fixed by welding or screw connection, so in the process of processing, it is not only troublesome, but also needs to be cooled after welding, resulting in The processing cycle is longer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ceiling fixing fastener that is convenient to disassemble. [0004] Technical scheme of the present invention is as follows: [0005] A ceiling fixing fastener, comprising a cylindrical fastener body, a buckle cover is provided on one side of the fastener body, and a ring groove is provided on the other side, and a limitin...
