Abstract
The utility model provides a double -end punching press formula inflation screw, including punching press nail and inflation nail, the inside of inflation nail is equipped with the through -hole that can hold the punching press nail, inflation nail outside even is equipped with protruding stupefiedly, the middle part of punching press nail becomes circular -arc, the punching press nail is formed by two, and the both ends of following closely from expanding respectively get into inside the through -hole, the top bilateral symmetry of one of them punching press nail is equipped with the screw hole, and screw hole internally mounted has self -tapping screw. The beneficial effect of the utility model: because the top bilateral symmetry of punching press nail is equipped with the screw hole, and screw hole internally mounted has a self -tapping screw, entering into the inflation nail when inside when the punching press nail, and fixed connection is followed closely through screw through -hole with the punching press to the screw makes the punching press nail be difficult for droing on expansion screw assembly's mounting surface, guarantee expansion screw assembly firmly.
Description
Technical field
This utility model belongs to hardware & tools, particularly relates to a kind of easy construction, connects more firm punching type swell fixture.
Background technology
Existing swell fixture structure is single, inconvenience of especially constructing, and first to hole, then bore nail.Usually there is holding the situation of unstable metope in the most existing swell fixture.
Utility model content
Technical problem to be solved in the utility model is to propose a kind of easy construction, connects more firm punching type swell fixture.Need not bore nail, it is achieved quickly connect.
For solving the problems referred to above, the technical solution of the utility model is, a kind of double-end punch pressure type swell fixture, and including punching press nail and expandable nail, the inside of described expandable nail is provided with the through hole that can accommodate punching press nail；The outside of described expandable nail is provided with convex stupefied uniformly；The middle part of described punching press nail becomes arc-shaped, and described punching press nail is formed by two, enters inside through hole from the two ends of expandable nail respectively；The symmetrical screw hole that is provided with in top of a described wherein punching press nail, screw hole is internally installed tapping screw.
Further, the import of described through hole becomes horn-like.
Further, the end of described expandable nail becomes coniform.
Further, described convex stupefied one-tenth zigzag.
Further, the two ends of described punching press nail become convergence shape.
Further, the length sum of described two punching presses nail is equal to the length of through hole.
The beneficial effects of the utility model: can accommodate the through hole that punching press is followed closely owing to the inside of expandable nail is provided with, when punching press nail punch is pressed into into expandable nail inside, expandable nail expands and realizes quickly connection.Need not bore nail easy construction quick.Simultaneously because the top of described punching press nail is symmetrical is provided with screw hole, screw hole is internally installed tapping screw, when punching press nail enters into expandable nail inside, punching press nail is fixedly connected on the installation surface of swell fixture assembly by screwing through hole and makes punching press follow closely difficult drop-off by screw, it is ensured that swell fixture assembly firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With specific embodiment, this utility model is further elaborated below in conjunction with the accompanying drawings.
As described in Figure 1, a kind of double-end punch pressure type swell fixture, including punching press nail 1 and expandable nail 2, the inside of described expandable nail 2 is provided with the through hole 2.2 that can accommodate punching press nail 1；The outside of described expandable nail 2 is provided with convex stupefied 2.1 uniformly；The middle part 1.1 of described punching press nail 1 becomes arc-shaped.Described punching press nail is formed by two, enters inside through hole from the two ends of expandable nail respectively, and during installation, punching press nail 1 extrudes to centre simultaneously so that expandable nail 2 is easier to expand and reduces installation procedure so that it is more firm that expandable nail 2 is combined with body of wall.The import of described through hole 2.2 becomes horn-like, it is simple to punching press nail 1 can quickly enter in through hole 2.2.Described convex stupefied 2.1 one-tenth zigzags, it is ensured that expandable nail 2 is more firm with wall connecting.The two ends of described punching press nail 1 become convergence shape, for convenience of extracting punching press nail 1, it is achieved quickly remove stage makeup and costume swell fixture.When punching press nail 1 enter into expandable nail 2 internal time, punching press nail 1 is fixedly connected on the installation surface of swell fixture assembly by screw hole 1.3 and makes punching press follow closely 1 difficult drop-off by tapping screw 1.2, it is ensured that swell fixture assembly firm.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in reader understanding's principle of the present utility model, it should be understood that protection domain of the present utility model is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete deformation and combination without departing from this utility model essence according to these technology enlightenment disclosed in this utility model, and these deformation and combination are still in protection domain of the present utility model.
