Abstract
The utility model relates to a fastener, which comprises a fastener body having a central outlet, wherein, a pivot pin is erected in the fastener body, and a pressing body provided with a pressing block is connected with the pivot pin in a pivot method. The cam-shaped pressing block can be used for pressing a belt body which is penetrated through the pressing block and the fastener body, and the utility model also comprises a spring provided with a buckling hook and erected at the middle part of the pivot pin and a leaf spring having one end fixed to the tail end of the pressing block and the other end connected with the buckling hook of the spring. When the pressing body rotates to an angle, the leaf spring can firmly press the belt body. The bottom surface of the leaf spring contacted with the belt body is provided with embossing in order to increase friction for gripping the belt body.
Description
The utility model relates to a kind of fastener, is used to clamp the object that tie is tied to frap.
General truck or binding object are when the fixed position, for making rope draw tightlyer, allow rope be attached at object more with the increase power that fraps, so often establish a fastener with both sides, the belt body on mat cloth matter surface passes fastener, fastener gives the clipping location again, make fastener tension belt body, reach the auxiliary effect that fraps, as Fig. 5, shown in 6, at present on the market institute generally the buckle structure of use comprise that mainly two ends are ringent button (40), the outlet (41) that its central authorities have formed, one presses body (50) to be flat on the prominent circular arc body (51) that is cam-like substantially of establishing in button (40) the inside and its front end bottom surface, this circular arc body has most lobes, belt body (60) can pass between pressure body (50) and the button (40) and pass outlet (41), and the front end that a rivet (42) is located at this button can supply to support a spring (421), and the effect of the circular arc body of mat spring and this cam-like can fasten belt body with the goods that fraps.Yet the lobe of this circular arc body is easy to belt body is galled or scratches, and makes that belt body can't be compacted and the goods that can't frap.
Because many shortcomings of the general fastener of using always, so develop the location holding structure of fastener of the present utility model.
The purpose of this utility model is to provide a kind of fastener, adds parts such as spring, shell fragment to form new location holding structure, to strengthen the clipping power of fastener to belt body on traditional fastener.
The keystone configuration of fastener of the present utility model, include a button, establish an outlet in the middle of this button, one pivot pin frame is in this button inside, one presses body to have a briquetting links to this pivot pin pivotally, firmly passes a belt body between this briquetting and this button but this briquetting is the shape of cam and voltage supply; Comprise that also a spring frame is located at the middle part place of this pivot pin, this spring has a clasp, and a shell fragment one end is fixed to the tail end of this briquetting, and its other end then links to the clasp of this spring, when this pressed the suitable angle of body rotation one, this shell fragment can firmly be pushed down this belt body.The basal surface of this belt body of contact of this shell fragment is the surface that is processed with embossing, to increase the friction force that it catches belt body.
Fastener of the present utility model is big to the clipping power of belt body, and the clipping belt body that firmly and not weares and teares is simple in structure, easy to use.
For further specifying structure of the present utility model, feature and practical purpose thereof describe in detail as the back in conjunction with the following drawings:
Fig. 1: be the three-dimensional exploded view of fastener of the present utility model;
Fig. 2, Fig. 3, Fig. 4: be the cutaway view of fastener of the present utility model, be used for the course of action of this fastener of illustrative;
Fig. 5 and Fig. 6 are the schematic perspective view of traditional fastener.
Fastener of the present utility model is consulted illustrated in figures 1 and 2ly, and whole pair of fastener mainly comprises a button (10), and it has pair of sidewalls, can be for setting up a pin (111) and be provided with a pair of hole (11) on sidewall; An outlet (12) is formed in the button, press body (30) to have a briquetting (31) that is cam-like approximately for one, its side has a groove (33) can supply putting spring (112), this briquetting (31) has a perforation (331) but supply and marketing (111) wears wherein, and spring (112) is set up on the pin (111); The centre that a groove (32) is formed at briquetting (31) can supply a ccontaining spring (34), and this spring (34) also is set up on this pin (111) and has a clasp; One shell fragment (20) is provided with a hook (21) with the one end can be for the clasp that links to spring (34), its other end utilizes rivet (341) to be fixed to the rear side of briquetting (31), this shell fragment (20) is haply against the lower surface of this briquetting (31), and the antiskid surface (22) that its lower surface is provided with embossing can and be caught belt body (60) for contact.
Operating mode of the present utility model is consulted shown in Fig. 2,3 and 4, and wherein belt body (60) passes between the bottom of briquetting (31) and button (10), and when rotating pressure body (30), this belt body can firmly be fixed between shell fragment (20) and the button.Wherein, as shown in Figure 4, the distance (A) between the front end of shell fragment (20) and the pin (111) is more preferably greater than the tail end and the distance between the pin (B) of shell fragment (20).The embossing face of shell fragment (20) is enough to push down belt body, and is unlikely and scratches belt body.
Claims (2)
1, a kind of fastener, include a button, establish an outlet in the middle of this button, a pivot pin is set up in this button inside, one presses body to have a briquetting links to this pivot pin pivotally, firmly passes a belt body between this briquetting and this button but this briquetting is the shape of cam and voltage supply;
It is characterized in that: comprise that more a spring frame is located at the middle part place of this pivot pin, this spring has a clasp, and a shell fragment one end is fixed to the tail end of this briquetting, and its other end links to the clasp of this spring, when this pressure body rotated an angle, this shell fragment firmly was pressed on this belt body.
2, fastener as claimed in claim 1 is characterized in that: the basal surface of this belt body of contact of this shell fragment is the surface with embossing, to increase the friction force that it catches belt body.
