Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

As shown in fig. 1 to 4, the present invention provides a plastic fastener, which includes a plastic female buckle 1 and a plastic male buckle 2 detachably connected to the plastic female buckle 1, wherein the plastic female buckle 1 is provided with a slot 3 and a relief hole 4 communicated with the slot 3, the plastic male buckle 2 includes a male buckle main body 5, an elastic structure 6 connected to one end of the male buckle main body 5, and a limit protrusion 7 connected to the other end of the male buckle main body 5, the male buckle main body 5 is provided with a through groove 8 and a limit step 9, the through groove 8 and the limit step 9 are both located between the limit protrusion 7 and the elastic structure 6, the limit step 9 is located on one side of the through groove 8 close to the elastic structure 6, the male buckle main body 5 is slidably connected to the slot 3, the limit protrusion 7 is used for opening end of the slot 3, the limit step 9 is located to the relief hole 4, the elastic structure 6 is used for abutting against bottom end of the slot 3, a threading space 10 is arranged between the elastic structure 6 and the male buckle main body 5.

After plastic box 1 and the equipment of

plastic pin thread

2, 5 cartridge of pin thread main part are in slot 3, and spacing step 9 stretches to dodge in the hole 4, and elastic construction 6 and the diapire elastic contact of slot 3, under elastic construction 6's spring action, spacing step 9 contradicts with the lateral wall of dodging hole 4 to carry on spacingly to plastic pin thread 2, avoid plastic pin thread 2 to break away from slot 3, improved the stability of plastic box 1 after the equipment with plastic pin thread 2. When the belt needs to be threaded, pressing force is applied to the limiting bulge 7 of the plastic male buckle 2, so that the plastic male buckle 2 moves inwards along the slot 3, the elastic structure 6 is compressed and stores elastic potential energy, the limiting step 9 is separated from the outer side wall of the through groove 8, the connecting belt 14 penetrates through the belt threading space 10 from top to bottom at the moment, then penetrates through the through groove 8 from bottom to top, and finally the pressing force applied to the plastic male buckle 2 is released, and under the action of resilience force of the elastic structure 6, the elastic structure 6 pushes the male buckle main body 5 to move outwards until the limiting step 9 clamps the connecting belt 14 on the outer side wall of the through groove 8, so that the connecting belt 14 is locked; when the length of the connecting band 14 needs to be adjusted, the plastic male buckle 2 is pressed inwards, so that the inward end of the male buckle main body 5 is enabled, and the limiting step 9 releases the clamping force on the connecting band 14. Owing to be provided with spacing arch 7, so when spacing arch 7 contradicted with the terminal surface of plastic box 1, prove that pin thread main part 5 inwards removes preset position, can wear the regulation of taking or connecting band 14 length this moment, also avoid pin thread main part 5 excessive inwards removal and lead to elastic construction 6 to damage or lose efficacy, play spacing guard action. The utility model has simple structure, convenient operation, convenient adjustment of the threading and connecting belt 14 and firm locking of the connecting belt 14.
