Abstract
The utility model relates to a fastener, in particular to a plastic fastener for an auto body outer panel, which comprises a fixing nut and a fastening screw. The fastening screw is arranged on the fixing nut through a nut hole. The top end of the fixing nut is provided with a flange, and the bottom end port of the fixing nut contracts inwards and is symmetrically provided with an extension and contraction port. A nut between the flange and the extension and contraction port is symmetrically provided with a lock platform, the fastening screw is formed by a screw rod and a head of the screw arranged on top of the screw rod, a stair-shaped protrusion is arranged on the periphery of the screw rod, and external threads are arranged on the screw rod below the protrusion. Mutual meshing through specific angles is achieved so that the fastener can completely meet the requirement for use strength and be assembled and disassembled repeatedly. The plastic fastener resolves problems that assembly of the existing metal screws and nuts is complicated and can not be finished without the aid of other tools, production efficiency is led to be low and enterprise economic benefit is affected. In addition, the plastic fastener has the advantages of being simple in structure, novel in design, convenient to assemble and disassemble, and especially suitable for fastening auto body outer panels.
Description
Technical field
The utility model relates to a kind of fastening piece, is specifically related to a kind of plastic fastener that is used for automobile skin.
Background technique
Present automobile skin snap-fittings, but requiring easily assembling and repeated disassembled and assembled, and require to guarantee under the situation that sealing and necessary intensity and pulling property do not reduce, the Sealing that all adopts the metal screw and nut and match with it uses the metallic screw nut, except that cost is higher than the defective of working of plastics far away, in the production line assembling, assembling is complicated and need just can finish installation by other instrument, makes manufacturing efficiency low, influences economic benefit of enterprises.
Summary of the invention
The purpose of this utility model is: a kind of collection sealing is provided and is assemblied in one fast, but and repeated disassembled and assembled, to solve existing metallic screw nut in the production line assembling, assembling is complicated and need just can finish installation by other instrument, make manufacturing efficiency low, influence the plastic fastener that is used for automobile skin of economic benefit of enterprises problem.
The utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of plastic fastener that is used for automobile skin, it is made of set screw nut and fastening screw trip bolt, it is characterized in that: fastening screw trip bolt inserts by nut bore and is installed on the set screw nut, the top of set screw nut is provided with the edge of a wing, nut bore bottom port is inwardly contraction-like, be symmetrically arranged with flexible mouthful on the port of bottom, be symmetrically arranged with Ka Tai on the nut between the edge of a wing and the flexible mouth, described fastening screw trip bolt is made of the head of a nail that screw rod and screw rod top are provided with, head of a nail surface is provided with the cross mouth, the screw rod circumference is provided with step-like projection, and the screw rod of projection below is provided with outside thread.
The utility model beneficial effect compared with prior art is:
This plastic fastener that is used for automobile skin is made of set screw nut and fastening screw trip bolt, set screw nut and fastening screw trip bolt are made by the acetal plastic material, the mutual interlock of screw-nut is reached satisfy fully the working strength requirement by special angle, except that its cost well below the metallic screw nut, but and repeated disassembled and assembled, during installation, earlier nut is pressed into stamping holes, again screw being passed automobile skin inserts in the nut, press...with one's finger and get final product on earth, during dismounting, can finish with the screw-driver screw of back-outing.Avoided existing metallic screw nut, assembling is complicated and need just can finish installation by other instrument, makes manufacturing efficiency low, influences the problem of business economic benefit.The utility model is simple in structure, novel in design, and assembly and disassembly is convenient, is specially adapted to the fastening use of automobile skin.
