The problem of the screw rod of current inflation screw hardly takes out is solved, fill easy, can resume wall body integrality and pleasing to the eye degree fast.
Description
Technical field
The utility model relates to technical field of hardware, is specifically related to one and enters the removable setscrew of wall.
Background technique
In construction-engineering project and daily process of assembling, often setscrew can be used, i.e. general said metallic expansive screw.Setscrew utilizes wedge shape gradient to impel to expand and produces friction bond stress, reaches fixed effect.One of setscrew is threaded stem, and one has tapered tail.Outer bread generally wraps up iron sheet cylinder (steel pipe), and iron sheet cylinder (steel pipe) has some otch near the half of tapered tail.They are filled in together in the hole that wall is accomplished fluently, then the nut of other end is tightened, nut pulls outward screw, tapered tail is drawn in iron sheet cylinder, iron sheet cylinder is by spreading, so tightly fixing on the wall, be generally used for fastening on the material such as cement, brick wall such as protective grating, canopy, air-conditioning, kitchen ventilator.
But the existing setscrew in market, tapered tail and screw rod are one, can not separate.When punch mounting positions is not suitable for or when fixture is as after protective grating, canopy, air-conditioning, kitchen ventilator etc. remove, because setscrew is difficult to take out smoothly, so often by its indwelling in original place or building, it is a lot of that the screw rod of a lot of setscrew stretches out metope, be difficult to allow it bounce back in body of wall subsides completely by knocking, so attractive in appearance the causing of building and family's interior trim is had a strong impact on, also there is potential risk to people.If by its rigid taking-up, then can leave larger hole on building or body of wall again, crime of injuries by explosive substances to buildings and goods therein or wall integrity.
Model utility content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, reasonable in design, easy to use enter the removable setscrew of wall, the screw rod solving existing setscrew is difficult to the problem of taking out, fill up easy, can quick-recovery body of wall integrity and aesthetics soon.
For achieving the above object, the technical solution adopted in the utility model is: it comprises bolt, nut, sleeve pipe; The outer cover of bolt is provided with sleeve pipe, and bolt is connected with nut; Described bolt is made up of screw rod and tapered cup nut; Tapered cup nut is connected to one end of screw rod; The two ends of described screw rod are respectively equipped with nut connecting thread and tapered cup nut connecting thread, and the outer end of screw rod is provided with hexagon head; The middle part of described tapered cup nut is provided with threaded connection hole, and the outside of tapered cup nut is provided with several guiding corner angle corresponding with bar shaped grooving on sleeve pipe.
Described guiding corner angle are blade shape guiding corner angle.
Described hexagon head and screw rod are integral type structure.
Working principle of the present utility model: when seated, entirety is put in hole pre-drilled on body of wall, while fastening nut, four guiding corner angle of tapered cup nut can be easy to cut in four bar shaped groovings of sleeve pipe, and the empty phenomenon of twisting or skidding can not occur; When punch mounting positions is not suitable for or when fixture is as after protective grating, canopy, air-conditioning, kitchen ventilator etc. remove, then oppositely can twist screw rod, because sleeve pipe is together with tapered cup nut crossed card, so screw rod can be easy to take out, the screw rod solving setscrew is in the past difficult to the problem of taking out, and after screw rod takes out, body of wall just only stays next very little hole, be easy to fill up, can quick-recovery body of wall integrity and aesthetics soon.
After adopting said structure, the utility model beneficial effect is: one described in the utility model enters the removable setscrew of wall, the screw rod solving existing setscrew is difficult to the problem of taking out, fill up easy, can quick-recovery body of wall integrity and aesthetics soon, and have structure simple, arrange rationally, the advantage such as fabricating cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the STRUCTURE DECOMPOSITION figure of bolt in the utility model.
Fig. 3 is the structural representation of tapered cup nut in the utility model.
Description of reference numerals:
Bolt 1, nut 2, sleeve pipe 3, screw rod 4, tapered cup nut 5, nut connecting thread 6, tapered cup nut connecting thread 7, threaded connection hole 8, guiding corner angle 9, bar shaped grooving 10, hexagon head 11.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Shown in Fig. 1-Fig. 3, the technological scheme that this embodiment adopts is: it comprises bolt 1, nut 2, sleeve pipe 3; The outer cover of bolt 1 is provided with sleeve pipe 3, bolt 1 is connected with nut 2; Described bolt 1 is made up of screw rod 4 and tapered cup nut 5; Tapered cup nut 5 is connected to one end of screw rod 4; The two ends of described screw rod 4 are respectively equipped with nut connecting thread 6 and tapered cup nut connecting thread 7, and the outer end of screw rod 4 is provided with hexagon head 11, when oppositely loosening the screw a little taking-up screw rod 4, common spanner can be used to operate; The middle part of described tapered cup nut 5 is provided with threaded connection hole 8, and the outside of tapered cup nut 5 is provided with several guiding corner angle 9 corresponding with bar shaped grooving 10 on sleeve pipe 3.
Described guiding corner angle 9 are blade shape guiding corner angle.
Described hexagon head 11 is integral type structure with screw rod 4.
The working principle of this embodiment: when seated, entirety is put in hole pre-drilled on body of wall, while fastening nut 2, four guiding corner angle 9 of tapered cup nut 5 can be easy to cut in four bar shaped groovings 10 of sleeve pipe 3, and the empty phenomenon of twisting or skidding can not occur; When punch mounting positions is not suitable for or when fixture is as after protective grating, canopy, air-conditioning, kitchen ventilator etc. remove, then can oppositely twist screw rod 4, because sleeve pipe 3 is together with tapered cup nut 5 crossed card, so screw rod 4 can be easy to take out, the screw rod solving setscrew is in the past difficult to the problem of taking out, and after screw rod takes out, body of wall just only stays next very little hole, be easy to fill up, can quick-recovery body of wall integrity and aesthetics soon.
After adopting said structure, this embodiment beneficial effect for: the one described in this embodiment enters the removable setscrew of wall, the screw rod solving existing setscrew is difficult to the problem of taking out, fill up easy, can quick-recovery body of wall integrity and aesthetics soon, and have structure simple, arrange rationally, the advantage such as fabricating cost is low.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
