Description

FIELD OF THE INVENTION

The present invention relates to the technical fields of insert buckles, in particular to an insert buckle head and an insert buckle. The application is based on the Chinese utility model patent application No. 200920058481.6 filed June 16, 2009 . The contents of the patent application are cited as reference in the document.

BACKGROUND OF THE INVENTION

An insert buckle in the prior art comprises an insert buckle head and an insert buckle body which are inserted, buckled and matched with each other. As illustrated in Fig. 1, one end of the insert buckle head 1 is an inserting end 2, and the other end of the insert buckle head 1 opposite to the inserting end 2 is a connecting end 10; the insert buckle head 1 can be provided with a connecting object such as braces by penetration through the connecting end 10; the inserting end 2 is used for being inserted and matched with the corresponding insert buckle body; and an elastic inserting pin 20 is respectively extended out of left and right sides of the inserting end 2. When the insert buckle head 1 is inserted, the elastic inserting pins 20 are clamped into clamping positions on the insert buckle body by virtue of the elastic deformation of the elastic inserting pins 20 so as to realize the inserting and buckling matching. Similarly, when the insert buckle is released, the elastic inserting pins 20 should be pressed as well, and the insert buckle can only be released after the elastic inserting pins 20 are driven to be withdrawn from the clamping positions on the insert buckle body. However, when the insert buckle is used, the elastic inserting pins 20 can produce a fatigue effect after repeated bending and thus are easy to break off. As the elastic inserting pins 20 and the insert buckle head 1 are subject to integrated forming, the insert buckle head 1 cannot be used again once the elastic inserting pins 20 are broken off. Moreover, as the insert buckle head 1 cannot be maintained, the whole insert buckle or the whole insert buckle head 1 should be replaced.

SUMMARY OF THE INVENTION

The invention aims to provide an insert buckle head for overcoming the defects in the prior art. As the insert buckle head adopts detachable buckle pins, the buckle pins are difficult to break off or damage. Moreover, the insert buckle head can be maintained, and the buckle pins can be replaced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiment

1

The embodiment relates to an insert buckle head. As illustrated in Figs. 2 and 3, one end of the insert buckle head 1 is an inserting end 2; the inserting end 2 is used for being inserted and matched with a corresponding insert buckle body which is a comparatively independent component (the insert buckle body is not shown in the figures); and the other end of the insert buckle head 1 opposite to the inserting end 2 is a connecting end 10 through which the insert buckle head 1 can be provided with a connecting object such as braces by penetration.
Left and right sides of the inserting end 2 are slidably provided with a detachable buckle pin 3 respectively. The buckle pins 3 are detachable, are independent components, and can be replaced, thus the insert buckle head 1 is a maintainable component. More importantly, the buckle pins are slidable and implement the inserting and buckling action by means of sliding and not by means of bending deformation. Therefore, the buckles pins 3 have higher structure strength, and are firmer and more durable, difficult to damage, and more difficult to break off.
Furthermore, the left and right sides of the inserting end 2 are provided with a guiding groove 5 respectively; the guiding grooves 5 are perpendicular to the insertion direction of the insert buckle head 1; guide rails 6 parallel to the guiding grooves 5 are formed on the buckle pins 3; the guide rails 6 of the buckle pins 3 are sleeved into the guiding grooves 5 of the inserting end 2; elastic components 4 for ejecting out the buckle pins 3 are arranged between the buckle pins 3 and the inserting end 2; a clamping position is formed by a groove on the left face of the inserting end 2 and a buckle pin 3 on the left side of the inserting end 2, and another clamping position is formed by a groove on the right face of the inserting end 2 and a buckle pin 3 on the right side of the inserting end 2; both ends of the inserting end 2 are provided with a stop slot 8 respectively; and stop pins 7 are fixed on the buckle pins 3 and inserted into the stop slots 8.
When the buckle pins 3 are assembled, the assembly of the insert buckle head 1 can be completed only by respectively mounting the left and right sides of the inserting end 2 of the insert buckle head 1 into springs, inserting the corresponding buckle pins 3, and mounting the stop pins 7, thereby the assembly is simple and convenient. In contrast, when the insert buckle head 1 is disassembled, the buckle pins 3 and the springs on the left and right sides of the inserting end 2 of the insert buckle head 1 can be taken out only by removing the stop pins 7, thereby the disassembly is simpler and more convenient. Moreover, both the buckle pins 3 and the springs on the insert buckle head 1 are replaceable, thus the maintenance is convenient.
The elastic components 4 are the springs, wherein first ends of the springs are sleeved on post bodies on inner faces of the buckle pins 3, and second ends of the springs lean against the inner face of the inserting end 2. Tail ends of the buckle pins are bent inwards and formed into guiding cambers.
Due to the arrangement of the guiding grooves 5 and the guide rails 6, the buckle pins 3 can slide along a specified direction. More specifically, due to the arrangement of the guiding grooves 5 and the guide rails 6, the buckle pins 3 can only slide along the insertion direction perpendicular to the insert buckle head 1. When the insert buckle head 1 is inserted into the corresponding insert buckle body, the buckle pins 3 are pressurized and slide towards the inner side direction of the insert buckle head 1; and after the buckle pins exceed the clamping positions on the insert buckle body, the buckle pins are ejected out under the action of the springs to fasten the insert buckle head 1 on the insert buckle body, consequently the connection is realized. In contrast, when the insert buckle is released, pressure is exerted on the buckle pins 3, and the buckle pins 3 are pressurized and slide towards the inner side direction of the insert buckle, consequently the insert buckle head 1 is released and can be separated from the insert buckle body at the time. After the insert buckle head 1 is separated from the insert buckle body, the buckle pins 3 are ejected out under the action of the springs and thus restored.
