Abstract

The utility model discloses an automatic belt buckle for fixing the belt objects and is mainly composed of an outer shell, a belt body fixing piece and an upper cover. The front end of the upper cover is processed into a box body and an automatic clamping and locking device is arranged in the box body. The outer shell is also provided with a belt body clamping device matching with the upper cover for locking and fixing a belt body. The advantage of the automatic belt buckle is that the locking with easy opening and closing between the upper cover and the outer shell is convenient and safe. The locking between the upper cover and the outer shell can not drop out because of the accidental action. The belt body used doesn't need the making of holes and the injury to the belt body is eliminated. The utility model also has the advantages of long service life, convenient use and free regulation of the belt body according to the actual demand.

Description

Automatic strap buckle

The utility model belongs to a kind of clamping device, particularly a kind of automatic strap buckle of fixedly strap-like objects.

At present, the band card of the waistband that uses of people or case and bag band mainly contains two kinds of perforation formula and left-hand thread formulas.Perforation formula band card is made up of quadra and the movable prong that is installed on the framework, the belt body of institute's adapted must punch, and movable prong penetrates in the eyelet of belt body, and in use movable prong can cause damage to belt body, thereby shortened the service life of belt body greatly, and profile is not attractive in appearance; Left-hand thread formula band card by the Button Block that has clasp and fixedly the stator of belt body form, the belt body of its adapted still must punch, and in addition, because its clasp is shorter, also can thread off because of user's involuntary maneuver; Therefore above-mentioned two kinds of band cards, can not regulate degree of tightness according to people's needs owing between the eyelet certain distance is arranged on the belt body of its adapted, very inconvenient in the use.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, a kind of belt body of not hindering is provided, and can regulates the automatic strap buckle of degree of tightness arbitrarily.

The utility model is achieved in that

The utility model has a shell, belt body stator and loam cake are installed on shell, the front end of loam cake is processed into box body, automatic buckling and locking device is installed in box body, make between loam cake and the shell and realize locking, said automatic buckling and locking device has two lock pins, and the lock pin symmetry is installed in the slideway of box body, between two lock pins back-moving spring is installed; Two plectrums that match with lock pin are installed in box body, and plectrum is installed in the box body by bearing pin; The button that matches with plectrum also is installed in the opening of box body front end; The belt body clamping device that matches with loam cake also is installed on shell, realizes being locked of belt body.

The utility model compared with prior art has following advantage:

1. because automatic buckling and locking device has been installed in loam cake, therefore, the locking between loam cake and the shell is more convenient, insurance, open easily, and will not thread off because of involuntary maneuver.

2. the belt body clamping device is installed in the enclosure, and therefore, the belt body of institute's adapted need not punch, and has both eliminated the damage to belt body, has prolonged the service life of belt body, can regulate the belt body degree of tightness according to actual needs arbitrarily again, and is very easy to use.
