Description

Snap close

Technical field

The utility model relates to snap close, particularly a kind of snap close that is used to pin casing and case lid.

Background technology

Chest is divided into casing and case lid two parts, and the lock of dress snap close is climbed part on casing, adorns latch hook on case lid.When case lid was covered, latch hook was that hook is lived the locking bolt that lock is climbed, and to keep the fixing of case lid, this is the common form of general suitcase.For example, structure is controlled in the improvement of Chinese patent 94245953 disclosed a kind of case class lockers, includes: a pedestal has opening room up; One cover piece, correspondence are covered on the top of this pedestal, have one first perforation and run through its upper and lower end face; One body; One plectrum is hubbed on this body top, and can it be to pivot between a unlatching and stowed position for axle; It is characterized in that: this cover piece has one second perforation and runs through its upper and lower end face, and adjacent corresponding with this first perforation; This body is to stretch through with its position, stage casing to be embedded in this first perforation, and hole axle that can this first perforation is an axle rotation start; This plectrum is horizontal mutually above the top end opening of this perforation respectively when being switched to this stowed position, has one first button and deploys and be located on the one side end face; One elastic top push piece is vertically installed on this room bottom, and apical grafting stretches out on the correspondence position of this plectrum from this second perforation in its top system, in order to pushing tow that this plectrum is made progress, it is switched on this enable possition from this stowed position; One fastener, be slidedly arranged on the top of this cover piece, and can in one fasten and the off-position between slippage, have one second button portion and be and be arranged on one side end face and this first button portion corresponding in opposite directions position, be to make this second button portion and this corresponding inserts of first button portion when it is moved to this closed position, in order to do with this plectrum clip is bound on this stowed position.Its weak point is, structure is complicated, and moulding is more stiff, and it is not too convenient to operate.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, modern design, easy to operate snap close.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of snap close comprises tenon and the following tenon that matches with described upward tenon, and the outside of last tenon has latch hook, and described have a plectrum on the tenon down, and described plectrum is articulated on the lower tenon base, articulates a locking bolt on the plectrum, it is characterized in that described locking bolt is a circular configuration.

Because the utility model has been taked above-mentioned technical measures, the contrast prior art has following advantage: structure is very simple, and snap close is reliable, is difficult for getting loose; The locking bolt of circular configuration is bigger than rectangle locking bolt, and is easy to operate, and modern design is generous.
