Square that a kind of slide fastener opening is used and latch piece
Technical field
The utility model relates to a kind of slide fastener field, square and latch piece that particularly a kind of slide fastener opening that cooperates slide fastener work is used.
Background technology
At present, the square that is used on the slide fastener opening mainly has straight-through guiding groove by a side, opposite side is that the square seat of semiclosed latch groove is formed, when the square seat is clipped to selvedge on the slide fastener, whole process is to lead directly to the band muscle that guiding groove clamps the slide fastener selvedge earlier, makes a call to an inclined hole afterwards on guiding groove, and purpose is that the base plate of inclined hole bottom can block the selvedge on the slide fastener, owing to play the contact pin that inclined hole adopts on the guiding groove if overexert, then thimble is disconnected easily; If firmly kick the beam, straight-through guiding groove folder does not strain at the selvedge on the chain, so difficult processing of whole process and square are prone to obscission.The latch that cooperates with square is hollow by inside mainly and the rectangular square that has a breach is formed, the breach dual-side is parallel breach, for this structure because the breach dual-side is parallel, so during the band muscle on clamping the slide fastener selvedge, be prone to the phenomenon that easily falls from slide fastener.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of processing simple, is difficult for coming off from slide fastener, the square and the latch piece that also have the slide fastener opening of environmental protection to use.
For achieving the above object, the technical scheme that the utility model adopted is: the square that a kind of slide fastener opening is used, it is characterized in that this square comprise the square seat, above the square seat, be provided with the square seat be one and the guide body that slide fastener is played guiding function, be provided with down first guiding groove of " eight " font in the described guide body, run through the square seat and be second guiding groove of " eight " font with being provided with in the corresponding square seat of first guiding groove; Described square seat opposite side also is provided with semi-enclosed the 3rd guiding groove; It is the 4th guiding groove of V font that described first guiding groove and second guiding groove connect as one formation both sides, back inwall, and described both sides inwall is that the 4th guiding groove of V font is formed with minimum spacing.
The latch piece that a kind of slide fastener opening is used, it is inner for hollow and have the strip square of breach to it is characterized in that this latch piece comprises, and the dual-side of described breach is respectively " Z " font limit; Described strip square can insert the 3rd guiding groove.
More excellent, the dual-side of described breach also can be respectively dentation fringe.
After adopting technique scheme, since first guiding groove and second guiding groove connect as one the back to form the both sides inwall be the 4th guiding groove of V font, described both sides inwall is that the 4th guiding groove of V font is formed with minimum spacing, add man-hour, salient point on the minimum spacing both sides that form on the 4th guiding groove can clamp band muscle on the slide fastener selvedge firmly, reduced the step of beating inclined hole in the prior art, so both realized easy processing, be difficult for coming off, also realized the purpose of environmental protection from slide fastener; Again because the latch piece that cooperates with the square seat comprises innerly is hollow and has the strip square of breach, the dual-side of described breach is respectively " Z " font limit, described strip square can insert the 3rd guiding groove, add man-hour, the breach dual-side divides other " Z " font limit can clamp band muscle on the slide fastener selvedge very securely, realized that processing is simple, be difficult for coming off to also have the purpose of environmental protection from slide fastener.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the square that a kind of slide fastener opening is used, this square comprises square seat 1, above square seat 1, be provided with square seat 1 for one and slide fastener is played the guide body 2 of guiding function, be provided with down first guiding groove 3 of " eight " font in the described guide body 2, run through square seat 1 and be second guiding groove 4 of " eight " font with being provided with in first guiding groove, the 3 corresponding square seats 1; Described square seat 1 opposite side also is provided with semi-enclosed the 3rd guiding groove 5; It is the 4th guiding groove 6 of V font that described first guiding groove 3 and second guiding groove 4 connect as one formation both sides, back inwall, and described both sides inwall is that the 4th guiding groove 6 of V font is formed with minimum spacing.The latch piece that a kind of slide fastener opening is used, this latch piece comprise inner for hollow and have the strip square 7 of breach, and the dual-side of described breach is respectively " Z " font limit 8; Described strip square 7 can insert the 3rd guiding groove 5.
Another embodiment of latch piece
Shown in Fig. 4 to 7, the latch piece that a kind of slide fastener opening is used, this latch piece comprise inner for hollow and have the strip square 7 of breach, and the dual-side of described breach also can be respectively dentation fringe 9; Described strip square 7 can insert the 3rd guiding groove 5.
During application, it is the 4th guiding groove 6 of V font that first guiding groove 3 and second guiding groove 4 connect as one formation both sides, back inwall, described both sides inwall is that the 4th guiding groove 6 of V font is formed with minimum spacing, add man-hour, salient point on the minimum spacing both sides that form on the 4th guiding groove 6 can clamp the band muscle on the slide fastener selvedge firmly, has reduced the step of beating inclined hole in the prior art, so both realized easy processing, be difficult for coming off, also realized the purpose of environmental protection from slide fastener; In addition, the latch piece that cooperates with square seat 1 comprises inner for hollow and have a strip square 7 of breach, the dual-side of described breach is respectively " Z " font limit, described strip square 7 can insert the 3rd guiding groove 5, add man-hour, the breach dual-side divides other " Z " font limit 8 can clamp the band muscle on the slide fastener selvedge very securely, realized that processing is simple, be difficult for coming off, also have the purpose of environmental protection from slide fastener.
Above-described only is the square used of the utility model slide fastener opening and the preferred implementation of latch piece; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
