Description
Technical field:
The present invention relates to a kind of bicycle folder, particularly a kind of interlocking is effective, double-wedge tongue locking type folder that can attenuate stamped metal material.
Technical background:
Although the kind of bicycle folder has manyly in the market, utilizes the folder difficulty of wedge tongue interlocking to seek trace, the splendid double-wedge tongue locking type folder of interlocking effect nowhere to search especially.
Summary of the invention:
Purpose of the present invention, be to provide a kind of and lock and open conveniently, interlocking is effective, cost is low, appearance effect is good double-wedge tongue locking type folder.The object of the present invention is achieved like this: double-wedge tongue locking type folder, comprise former piece, consequent, band is bolt and double-wedge tongue spare, it is characterized in that: former piece is that to strike out the opening of three flange with sheetmetal box-like, an earhole respectively is with at the two ends of former piece opening part flange, three holes of equidistant arrangement on the opposite side of former piece opening, mesopore is for being with the hole that penetrates of bolt, two lateral opening be the pilot hole of double-wedge tongue spare, middle part at the bottom of the former piece box is turned over and is stuck up ear, turn over stick up on the ear with holes, consequent is one side roll coil of strip circle, the sheetmetal blanked part of another sideband flanging, on the flanging of consequent with two interlocking holes, the volume circle hole of consequent and two earholes of former piece are rotatably connected, band penetrates mesopore to bolt, is screwed in the screw of double-wedge tongue again, penetrates turning over of former piece again and sticks up in the earhole, and then will be with the end points place of bolt is put packing ring and mixes pin, two thes tip of the tongue of double-wedge tongue spare penetrate in two pilot holes of former piece.
The invention has the beneficial effects as follows: utilize two interlocking holes of two pilot holes and the former piece of consequent, carry out interlocking with double-wedge tongue spare, intensity is better than traditional interlocking mode, utilizes band that bolt is screwed and advances double-wedge tongue spare, can make structure of the present invention simpler.
