Abstract

The invention relates to an expansion buckle which is composed of a subsidiary buckle and a mother buckle. The head portion of the mother buckle is provided with a cap with a hole in the middle, and the tail part of the mother buckle is provided with clamping tongues. The subsidiary buckle is of a nail type structure. The subsidiary buckle is of a nail type structure, a nail body part is provided with grooves in a manufacture mode, and the number of the grooves is the same as that of the clamping tongues of the mother buckle. Each groove is divided into two parts, wherein the part close to the tail end of the subsidiary buckle is a first journey groove, the other part is a second journey groove, the two journey grooves are divided by a cylinder structure, the first journey groove, from one bottom face of a cylinder toward the tail direction of the subsidiary buckle, is arranged to be a first cone-shaped structure, and the second journey groove, from the other bottom face of the cylinder toward the nailhead direction of the subsidiary buckle, is arranged to be a second cone-shaped structure.

Description

A kind of expansion buckle
Technical field
The invention belongs to buckle interface arrangment technical field, be specifically related to a kind of inflating clip buckle structure.
Background technique
Inflating clip buckle structure commonly used is two kinds of forms at present:
One, screw-thread fit formula expansion buckle.The screw thread that the sub-buckle outer surface of this kind expansion button and box internal surface are designed to mate, and the sub-buckle head design has cross recess.Reusable 3-4 time of this kind expansion button, but mould is comparatively complicated, and manufacture cost is relatively high; And this kind expansion buckle need rise by cross and assemble and dismantle, and the take-down time is long.
Two, non-dismountable formula expansion buckle.The sub-buckle of this kind expansion buckle and box smooth surface are designed to a joint stroke limit between sub-buckle and the box, adopt back-off structure between snap button.When moving ahead propelling, sub-buckle with the box distending, realizes expansion button clamping locking function.This buckle is easy for installation, and clamping power is large, and fixing reliable, cost is relatively low, but needs destructive dismounting, not reproducible use.
Therefore existing these two kinds of expansion buckles all can not be reused for a long time, and install, dismantle very inconvenience, and the required activity duration is longer.
Summary of the invention
The objective of the invention is prior art is proposed improvement project, this technology can so that buckle can repeated multiple timesly use.
The present invention is achieved by the following technical solutions:
A kind of expansion buckle is comprised of sub-buckle and box two-part; The head of described box is the cap of middle with hole, 3-5 the block tongue of afterbody for being connected with cap;
Described sub-buckle is nail formula structure, and its nail body is partly made with the identical groove of box block tongue quantity, and each groove is divided into two-part, and the part of close sub-buckle afterbody is the first stroke groove, and another part is the second stroke groove, is separated by a cylindrical structural between the two stroke grooves; Caudal directions to sub-buckle is set to the first cone structure from cylindrical bottom surface in the first stroke groove, is provided with the second cone structure from columniform another bottom surface to sub-buckle ailhead direction in the second stroke groove;
The outer surface of described cylindrical structural is provided with box locking clamping groove;
The inside at the nearly cap of described block tongue place is provided with limit dais, and described limit dais is used for stoping the sub-buckle head to pass.
The afterbody of described sub-buckle is round platform or conical structure.
Described block tongue is 3 or 4.
The beneficial effect that the present invention compares with prior art is:
1, sub-buckle is designed to two joint strokes, and wherein the first segment stroke is realized expansion button clamping locking function; The second section stroke,, whole expansion button release.At this moment, expansion button can directly be taken down dismounting, finishes the connected element field-strip.
2, meticulous, the reliable performance of this kind inflating clip buckle structure is made easy to processly, and cost is low, and is reusable, and assembling and easy removal, and the activity duration is short.

Embodiment
The below describes embodiments of the invention in detail.
A kind of expansion buckle is comprised of sub-buckle and box two-part; Described box head is the cap of middle with hole, 3-5 the block tongue of afterbody for being connected with cap; Be preferably 3 or 4 block tongues; The outer surface of all block tongues is on same cylindrical outer surface; The inside at the nearly cap of described block tongue place is provided with limit dais, in other embodiments of the invention, limit dais can be set can realize the present invention too.
Described sub-buckle is nail formula structure, and its nail body is partly made with the identical groove of box block tongue quantity, and each groove is divided into two-part, and the part of close sub-buckle afterbody is the first stroke groove, and another part is the second stroke groove, is separated by a cylindrical structural between the two stroke grooves; Caudal directions to sub-buckle is set to the first cone structure from cylindrical bottom surface in the first stroke groove, is provided with the second cone structure from columniform another bottom surface to sub-buckle ailhead direction in the second stroke groove;
The outer surface of described cylindrical structural is provided with box locking clamping groove;
When inflating clip buckle during in free state, the clamping back-off is positioned at the nearly sub-buckle tail end of the first stroke groove place; When inflating clip buckle during in released state, the clamping back-off is positioned at the second stroke groove.
The outer surface of described the first cylindrical structural is provided with box locking clamping groove, and described groove adapts with the clamping back-off.
The purpose of described limit dais is to prevent that sub-buckle is deviate from from box when release.
In other embodiments of the invention, the width of the distance of each stroke and snap button locking clamping groove is adjusted according to different needs, and any variation of these data all affects technological scheme of the present invention.
Be the knocked-down free state of the present invention referring to Fig. 1.Box 2 joint ends are in the sub-buckle 1 first segment stroke groove, at this moment, have the gap between the snap button of expansion button, without coupling mechanism force.
Referring to Fig. 2, be sub-buckle tomograph of the present invention.Mainly comprise following a few part in the sub-buckle structure:
Box the first stroke groove 3, this groove are box original state position;
Spacing and the firm effect of clamping of clamping is played in box clamping back-off present position when box locking buckling groove 4, this groove are expansion button clamping assembling condition, this groove up/down steps;
The second stroke groove 5, this groove are that box is made a concession expansion button release effect.
Referring to Fig. 3, be box tomograph of the present invention.Mainly comprise following two-part in the box structure:
Second section stroke limit platform 6, this prevents that sub-buckle from directly passing box and coming off when box 2 release, avoid sub-buckle to separate with box and the generation that need re-assembly even lose phenomenon.
Box locking clamping back-off 7 is made time spent clamping locking in order to the expansion button assembling.
The end of block tongue is provided with the clamping back-off, and the end of described clamping back-off is square, circular chamfering or oval chamfering.
