Abstract

The utility model relates to a structure-improved buckle. The utility model is characterized in that two abutting components which are formed in the integral forming mode are arranged between two clamping components of a male buckle of the buckle, and the corresponding portion on the female buckle is provided with a fastening device; the male and the female buckles are buckled, after the male buckle penetrates through and enters to a predetermined depth, the two abutting components are contacted with the fastening device of the female buckle, the two abutting components which are influenced by the inclination of the fastening device surface can gradually be poked, and the two abutting components respectively curve slightly and displace towards both sides; when the male buckle and the female buckle are fastened to position, the two abutting components are simultaneously abutted correspondingly on each clamping component, and the fastening effect can be ensured, the exfoliation and the separation are not easy to occur by touching.

Description

Improve the fastener of structure

The utility model belongs to locked part, relates in particular to a kind of fastener that improves structure.

The general fastener of commonly using, as shown in Figure 1, combine by a box 10 and a pin thread 11, wherein box 10 is made hollow form, and each one-body moldedly has a blocking breach 101 at its both sides appropriate location, and the one-body molded blocking parts 111 that two symmetries are arranged on the pin thread 11, when being fastened and connected, pin thread 11 can utilize two set on it blocking parts 111 to be located in the hollow inside of box 10 accordingly, and the clasp 112 by each blocking parts 111 ends institute moulding be located on the set blocking breach 101 of box 10, make it to be connected to each other and be that one, the unlikely separation that gets loose, its shortcoming are in conjunction with not firm, as long as touch each blocking parts 111 accidentally, just may cause each blocking parts to break away from from the blocking location, just, in a single day each blocking parts 111 breaks away from the blocking location, can cause separating of box 10 and pin thread 11 at once, as long as box 10 loses with pin thread 11 and is connected, the article that people carry will be lost in wrapping, and bring unnecessary loss.

The purpose of this utility model is to provide a kind of fastener that improves structure, the fastening of male and female button can be increased prevent together the clamping structure that breaks away from, to guarantee to fasten effect, by adjusting the elastic force of spring, to adapt to the fastening needs of different occasions.

The utility model adopts following technical scheme:

The utility model improves the fastener of structure, comprising: a box generally be hollow form, and each one-body moldedly has a blocking breach at its both sides appropriate location; One pin thread, the one-body molded blocking parts that two symmetries are arranged on it can utilize these two blocking parts being located in the hollow inside of box accordingly, and by the clasp of described each blocking ends institute moulding, be located in one by one on the set blocking breach of box, so that it is connected to each other one; Described pin thread is one-body molded between these two blocking parts two top-holding part spares; Box hollow inside except that on the wall one-body molded have a guide rail and below be provided with the limiting part, it is at Fastening device of bottom surface appropriate location installing, Fastening device is to be pushed away by an axostylus axostyle, compression spring and one to pull out parts and combine, wherein axostylus axostyle is the bottom that is installed in box, just be positioned at the inside of limiting part, the compression spring is to be set on this axostylus axostyle, and described pushing away pulled out parts and can be provided with a guidance part in the side that corresponding box inwall is provided with guide rail.

The utility model improves the fastener of structure, by between two blocking parts of pin thread, being provided with top-holding part spare, on the inner wall of box hollow, be provided with guide rail and limiting part, the fastening of male and female button has been increased prevent together the clamping structure that breaks away from, guaranteed the fastening effect, and it can change the elastic force of spring arbitrarily, to be suitable for the needed fastening effect in various places.

Specifically narrate embodiment below in conjunction with accompanying drawing:

Fig. 1 is a perspective view of commonly using fastener

Fig. 2 is a planar structure combination schematic diagram of the present utility model

Fig. 3 is vertical cross-sectional schematic of the utility model box

Fig. 4 is the horizontal cross-sectional schematic of the utility model box

Fig. 5 is the planar structure schematic diagram of the utility model pin thread

Fig. 6 is the utility model combining structure cross-sectional schematic

Consult Fig. 1 to shown in Figure 5, the utility model improves the fastener of structure, formed by a box 2 and a pin thread 3, wherein, box 2, generally be hollow form, and each one-body moldedly has a blocking breach 21 at its both sides appropriate location, box 2 hollow inside except that on the wall one-body molded have a guide rail 22 and below be provided with the limiting part 23, it is equiped with a Fastening device 24 at the bottom surface appropriate location, this Fastening device 24 is by an axostylus axostyle 241, compression spring 242 and one push away and pull out parts 243 and combine, wherein axostylus axostyle 241 is the bottoms that are installed in box 2, just be positioned at the inside of limiting part 23, compression spring 242 is to be set on this axostylus axostyle 241, describedly push away that to pull out parts 243 be also to be set on the axostylus axostyle 241 after the spring 242 continue compression, pull out parts 243 and can follow certain route and carry out displacement for making to push away, push away and pull out parts 243 and can be provided with a guidance part 245 in the side that corresponding box 2 inwalls are provided with guide rail 22, this guidance part 245 is installed and is stretched in the guide rail 22, under mutual guide function, it is accurate to guarantee to push away the displacement action that pulls out parts 243.

Pin thread 3, the one-body molded blocking parts 31 that two symmetries are arranged on it, can utilize these two blocking parts 31 to be located in the hollow inside of box 2 accordingly, and by the clasp 311 of described each blocking parts 31 ends institute moulding, be located in one by one on the set blocking breach 21 of box 2, be one so that it is connected to each other, described pin thread 3 is one-body molded between these two blocking parts 31 two top-holding part spares 32, when action, machine contacts one by one with each blocking parts 31 in due course.

Operation principle of the present utility model is, when pin thread 3 and box 2 carry out snap action, pin thread 3 can be located in one by one by the clasp 311 of each blocking parts 31 ends institute moulding on the set blocking breach 21 of box 2, so that being connected to each other, it is one, with commonly use the fastener situation different be, when wearing, pin thread 3 enters box 2 to desired depth, two top-holding part spares 32 touch pushing away when pulling out parts 243 of box 2 Fastening devices 24, be subjected to pushing away the influence of pulling out parts 243 surface tilt degree, two top-holding part spares 32 promptly can little by little be pushed aside, and respectively to the slight curving displacement in both sides, treat that pin thread 3 and box 2 arrive when fastening the location, two top-holding part spares 32 just also can be resisted against on each blocking parts 31 simultaneously accordingly, guaranteed the blocking effect of the utility model fastener, even touched this moment, since have two top-holding part spares 32 effectively hold against, each blocking parts 31 also is not easy to occur the situation that comes off and separate, can not cause separating of each blocking parts 31 and blocking breach 21, the spring force of the utility model fastener can change arbitrarily, to be suitable for the needed fastening effect in various places.

In sum, the utility model improves the fastener of structure, and structural design is simple, reasonable, has overcome the defective of commonly using fastener, reaches design purpose.
