Abstract
The present invention proposes a kind of buckle-type double-end punch compression swelling screw assembly, including punching press nail and expansion sleeve, and the inside of the expansion sleeve, which is provided with, can accommodate the through hole of punching press nail；The outside of the expansion sleeve is uniformly provided with convex stupefied；The middle part of the punching press nail is into arc-shaped, and the punching press nail is constituted by two, is entered respectively from the two ends of expansion sleeve inside through hole；The end of the punching press nail is symmetrical to be provided with buckle, and the two ends of the expansion sleeve are provided with the card convex being engaged with buckle.Beneficial effects of the present invention：The through hole of punching press nail can be accommodated because the inside of expansion sleeve is provided with, quick connection is realized in expansion sleeve expansion when punching press nail punch is pressed into inside expansion sleeve, it is not necessary to bore nail easy construction quick.The end of the nail of punching press simultaneously is symmetrical to be provided with buckle, and the two ends of expansion sleeve are provided with the card convex being engaged with buckle.When punching press nail is entered inside expansion sleeve, buckle is engaged with card convex so that punching press nail will not drop out of expansion sleeve ensure that the stability of swell fixture.
Description
Technical field
The invention belongs to hardware ＆ tools, more particularly to a kind of easy construction, more firm punching type swell fixture is connected.
Background technology
Existing swell fixture structure is single, especially constructs inconvenient, first to drill, then bores nail.Existing expansion simultaneously
Usually there is the situation for holding unstable metope in screw.
The content of the invention
The technical problems to be solved by the invention are to propose a kind of easy construction, connect more firm punching type swell fixture.No
Need to bore and follow closely, realize quick connection.
To solve the above problems, the technical scheme is that, a kind of buckle-type double-end punch compression swelling screw assembly, including punching press
Nail and expansion sleeve, the inside of the expansion sleeve, which is provided with, can accommodate the through hole of punching press nail；The outside of the expansion sleeve is uniformly provided with convex
It is stupefied；The middle part of the punching press nail is into arc-shaped, and the punching press nail is constituted by two, is entered respectively from the two ends of expansion sleeve in through hole
Portion；The end of the punching press nail is symmetrical to be provided with buckle, and the two ends of the expansion sleeve are provided with the card convex being engaged with buckle.
Further, the import of the through hole is into horn-like.
Further, the end of the expansion sleeve is into coniform.
Further, it is described convex stupefied into zigzag.
Further, the two ends of punching press nail are into convergence shape.
Further, the length sum of two punching presses nail is equal to the length of through hole.
Beneficial effects of the present invention：The through hole of punching press nail can be accommodated because the inside of expansion sleeve is provided with, when punching press nail punch is pressed into swollen
Quick connection is realized in expansion sleeve expansion when inside expansion set, it is not necessary to bore nail easy construction quick.End of the nail of punching press simultaneously or so pair
What is claimed is provided with buckle, and the two ends of the expansion sleeve are provided with the card convex being engaged with buckle.When punching press nail is entered inside expansion sleeve
When, buckle is engaged with card convex so that punching press nail will not drop out of expansion sleeve ensure that the stability of swell fixture.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The invention will be further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As described in Figure 1, a kind of buckle-type double-end punch compression swelling screw assembly, including punching press nail 1 and expansion sleeve 2, the expansion
The inside of set 2, which is provided with, can accommodate the through hole 2.2 of punching press nail 1；The outside of the expansion sleeve 2 is uniformly provided with convex stupefied 2.1；It is described
The middle part 1.1 of punching press nail 1 is into arc-shaped.The punching press nail is constituted by two, is entered respectively from the two ends of expansion sleeve inside through hole,
During installation punching press nail 1 simultaneously to centre extruding so that expansion sleeve 2 be easier expand reduce installation procedure so that expansion sleeve 2 with
It is more firm that wall is combined.The import of the through hole 2.2 is easy to punching press nail 1 to quickly enter through hole 2.2 into horn-like
In.Convex stupefied 2.1 one-tenth zigzags, it is ensured that expansion sleeve 2 is more firm with wall connecting.The two ends of punching press nail 1 into
Shape is restrained, for convenience of that can extract punching press nail 1, realization is quickly removed stage makeup and costume to swell fixture.End of the punching press nail 1 or so pair
What is claimed is provided with buckle 1.2, and the two ends of the expansion sleeve 2 are provided with the card convex 2.3 being engaged with buckle 1.2, when punching press nail 1 enters
When entering to 2 inside of expansion sleeve, buckle 1.2 is engaged with card convex 2.3 so that punching press nail 1 will not drop guarantor out of expansion sleeve 2
The stability of swell fixture is demonstrate,proved.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in the original that reader understands the present invention
Reason, it should be understood that protection scope of the present invention is not limited to such especially statement and embodiment.The ordinary skill of this area
Personnel can be made according to these technical inspirations disclosed by the invention the various other various specific deformations for not departing from essence of the invention and
Combination, these deformations and combination are still within the scope of the present invention.
