The purpose of the utility model can be realized by the following technical proposal: plastic steel track tooth zip fastener, including drawing zipper head and a pair of chain belt, the chain belt includes the chain cloth and fixes the same chain tooth of one row of interval on the chain cloth, draws zipper head both sides to open the through-hole that supplies the chain tooth to stretch out, and the through-hole below all has L type limiting plate, a serial communication port, the chain tooth includes that the front end is curved tooth head portion and rear end and is the flat tooth afterbody, tooth head portion front end face is opened has the level and is set up the breach, and tooth head portion both sides are all opened the articulated recess that supplies the tooth head portion embedding of other side chain tooth, have the protrusion in the articulated recess and can block the cardboard in another chain tooth breach into, the draw-in groove that supplies the chain cloth card to block is opened to the tooth afterbody, the gliding step of zip fastener head is drawn to the surface division about the tooth afterbody, L type limiting plate.

The chain tooth passes through the hot pressing to be fixed on the chain cloth, and the tooth afterbody of chain tooth passes through the through-hole and exposes outside, and step on the tooth afterbody is drawn zipper head inside by L type limiting plate parcel, draws zipper head when stimulateeing, and L type limiting plate slides along the step, and the step makes the chain tooth fold in drawing zipper head more easily, makes simultaneously draw zipper head to be difficult to block with the chain tooth for draw zipper head to slide more smoothly steady.

Furthermore, the height of the gap is 0.8-1 mm, and the thickness of the clamping plate is 0.7-0.8 mm.

Further, the height of the clamping groove is the same as the thickness of the chain cloth.

Furthermore, the bottom of the clamping groove is an arc-shaped surface, a cylindrical clamping head is arranged at the edge of the chain cloth, and the clamping head is embedded into the arc-shaped surface.

Furthermore, the outer side face of the clamping plate is flush with the side face of the zipper teeth.

Further, the tooth tail part of the zipper tooth is flush with the edge of the tail part of the zipper head.

The zipper teeth are made of plastic steel materials, and the structure is firmer.

Compared with the prior art, the plastic steel rail tooth zipper has the advantages that:

1. the inside cardboard that can imbed the breach for displacement about can not taking place between chain tooth and the chain tooth, the stability of improvement zip fastener, dislocation about adjacent chain tooth can not taking place in the articulated recess.

2. The tooth afterbody has the step that supplies to draw the zipper head gliding for draw the zipper head more steady smooth and easy in the pulling process.
