Abstract
The utility model discloses setscrew that is a kind of detachable and can reusing, belong to setscrew field.Setscrew includes screw, nut, metallic cylinder, and screw is provided with external screw thread, and nut is twisted in screw topmost, screw other end outer wrapping metallic cylinder, characterized in that, the upper end of metallic cylinder is provided with metallic cylinder compliant portion, lower end is to be unlikely to deform part.In use, extruding metallic cylinder compliant portion by tightening nut, make its deformed dilation, reach the fixed effect of expansion.When needing to take out setscrew, nut 2 is up twisted, nut upper end drives the easy deformation part of metallic cylinder by nut lower end fixed thereto, the pulling force that the easy deformation part of metallic cylinder is difficult deformation part by nut lower end and metallic cylinder produces tensile deformation, it is convenient to take out so as to lose dilation.It is simple in construction, easy for installation and with low cost using setscrew that is of the present utility model detachable and can reusing.
Description
Technical field
The utility model is related to setscrew that is a kind of detachable and can reusing, and more particularly to one kind is detachable simultaneously
The setscrew that can be reused, belongs to setscrew field.
Background technology
Setscrew is a kind of conventional fixed screw, preferably fixed article can will needed to be fixed on wall etc.
Position.At present, it is architectural generally to be fastened object with setscrew, the spiral shell of general setscrew by expansion sleeve, with conehead
Bar and nut etc. are constituted, and one end of wherein expansion sleeve is provided with three or more expansion slots, and there is conehead one end of screw rod, during installation
Drilled first on wall, being put into hole and then tighten nut by screw rod, expansion sleeve pulls screw rod, and the conehead extruding of screw rod is swollen
Expansion set pipe is so that expansion sleeve expanding end and the swelling that drilled on wall, mounted object is fixed on wall.It is existing
Setscrew enter drilling in be difficult because running into certain resistance into hole, it is necessary in one end relative to conehead of screw rod
It could make it that setscrew enters depth in required drilling with aid such as hammer；Brill of the setscrew on wall
In hole it is fixed after if there is without and need to extract, then the resistance run into is big and wastes time and energy；Enable the expanding screw of extraction
Silk be able to can not also be used because stress causes setscrew to deform greatly, and this is also a kind of wave to resource in certain degree
Take.
The content of the invention：
Regarding to the issue above, the utility model aims to provide Novel expansion bolt that is a kind of detachable and can reusing,
Its convenient taking-up after fixing, and can reuse.
What the technical solution of the utility model was realized in：
A kind of detachable Novel expansion bolt that can simultaneously reuse of the present invention, including screw (1), nut (2), round metal
Cylinder (3), screw (1) is provided with external screw thread (1a), and nut (2) is twisted in screw (1) topmost, and screw (1) other end outer wrapping
Metallic cylinder (3), the upper end of metallic cylinder (3) is provided with metallic cylinder compliant portion (3c), and lower end is to be unlikely to deform part
(3d)。
Further, the internal thread corresponding with the external screw thread (1a) on screw is provided with described nut (2).
Further, described nut (2) is shaped as hex nut.
Further, the easy deformation part (3c) of described metallic cylinder is by relatively easy deformation, the reliable iron material of intensity
It is made.
Operation principle：
When being not used, nut (2) is screwed in screw (1) topmost, and screw is in non-deformed state, can head into the things such as wall
In body.
In use, setscrew is inserted in the drilling in wall and nut (2) is rotated, the hole accomplished fluently on wall is filled in together
In, then nutting (2), nut lower end (2b) extruding easy deformation part (3c) of metallic cylinder, make the easy deformation part of metallic cylinder
(3c) expands, and is then tightly secured on wall.When needing to take out setscrew, when nut (2) is up twisted, with nut
End (2a) is moved up, and the easy deformation part (3c) of metallic cylinder, metallic cylinder are driven by nut lower end (2b) fixed thereto
Easy deformation part (3c) is produced tensile deformation by nut lower end (2b) and the metallic cylinder pulling force for being difficult deformation part (3d), from
And dilation is lost, it now can conveniently take out screw.Preferably, screw after removal can be with for the metal material plasticity of the screw
Reuse.
Compared with prior art, the beneficial effects of the utility model are as follows：
The of the present utility model detachable and Novel expansion bolt that can reuse is because of the easy deformation part plasticity of metallic cylinder
Good, Novel expansion bolt easily switches between swelling state and non-expansion state, and convenient fixed and dismounting is repeatable to make
With its is simple in construction, easy for installation, with low cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is that the utility model is fixed using the state diagram entered；
Fig. 3 is state diagram when the utility model takes out；
In figure：1- screws, 2- nuts, 3- metallic cylinders, 1a- screw threads, 2a- nuts upper end, 2b- nuts lower end, 3c- metals
The easy deformation part of cylinder, 3d- metallic cylinders are difficult deformation part.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of Novel expansion bolt, including screw 1, nut 2, metallic cylinder 3, screw 1 is provided with outer spiral shell
Line 1a, nut 2 is twisted in the top of screw 1, and the other end outer wrapping of screw 1 metallic cylinder 3, and the upper end of metallic cylinder 3 is provided with
Metallic cylinder compliant portion 3c, lower end is to be unlikely to deform part 3d.It is provided with nut 2 relative with the external screw thread 1a on screw
The internal thread answered.Nut 2 is shaped as hex nut.The easy deformation part 3c of described metallic cylinder is made by material.
When being not used, nut 2 is screwed in screw 1 topmost, and screw is in non-deformed state, can head into the objects such as wall
In.
In use, as shown in Fig. 2 by setscrew insert wall in drilling in and rotate nut 2, fill in together on wall
In the hole accomplished fluently, then nutting 2, the nut lower end 2b extruding easy deformation part 3c of metallic cylinder, make the easy deformations of metallic cylinder
Divide 3c expansions, be then tightly secured on wall.When needing to take out setscrew, as shown in figure 3, when nut 2 is up twisted, with
Nut upper end 2a to move up, the easy deformation part 3c of metallic cylinder, round metal are driven by nut lower end 2b fixed thereto
Cylinder easily deformation part 3c is produced tensile deformation by nut lower end 2b and the metallic cylinder pulling force for being difficult deformation part 3d, so as to lose
Dilation is gone, screw now can be conveniently taken out.Preferably, screw can be repeated the metal material plasticity of the screw after removal
Use.
By the position of adjusting nut 2 up and down, so as to change the easy deformation part 3c of metallic cylinder dilation, reach conveniently
Purpose that is fixed and taking out setscrew, setscrew is repeatable to be utilized.
