Abstract
The utility model belongs to the technical field of the fastener, especially, relate to a bolt formula inflation nut, constitute by metal nut, metal taper pin, have the screw thread supporting with the screw in the metal nut first half, latter half of division of metal nut have many with the parallel incision of axle, metal taper pin shape and size and the latter half of complete network of metal nut, the metal taper pin inserts the metal nut, the screw is through withstanding the metal taper pin when fixing, messenger's metal nut lower extreme distending reaches fixed effect. Rely on metal nut inflation, play fixed object's effect to two major defects of inflation screw have effectively been solved. The power of expansion metal nut is inside distending, is difficult to the damage by the body that expands. Bolt formula inflation nut can be used to on all solid materials of can not the tapping linking such as industry, construction industry, like marble, granite, building wall, the cement body etc. Act as the tapping nut, play the fastening effect, safe and reliable, the installation is simple, convenient moreover.
Description
Technical field
This utility model belongs to technical field of fastening, particularly relates to a kind of bolt-type expansion nut.
Background technology
To setscrew, everybody is the strangest, and it is to utilize wedge shape gradient to promote to expand generation friction bond stress, reaches fixed effect.During installation, first being filled in by setscrew in the hole being drilled on wall, then split nut, screw is pulled outward by nut, and tapering is drawn in iron sheet cylinder, and iron sheet cylinder, by distending, plays the effect of fastening.Its defect has 2 points: one is that screw is outwards exerted oneself, and easily damage is by swollen body；Two be screw expose outside head part unsightly, affect integrated artistic and outward appearance.
Utility model content
In order to solve above-mentioned technical problem, the utility model proposes a kind of bolt-type expansion nut, become by metal nuts, metal cone pin bank, having the screw thread supporting with screw in metal nuts first half, metal nuts is latter half of has a plurality of otch parallel with axle, and metal cone pin-shaped shape is latter half of with size and metal nuts supporting, metal taper pin inserts metal nuts, Gu timing screw is by withstanding metal taper pin, makes metal nuts lower end distending, reach fixing effect.
Described metal nuts Front-end Design becomes to extend out the conical surface, increases and screw or the contact surface of packing ring.
Described kerf is strip rectangle, quantity 2～8.
Described metal nuts is shaped as strip cylinder.
Described metal taper pin is strip Rotary-table.
This utility model has the beneficial effects that:
Use for reference the principle of setscrew, metal nuts is carried out special handling, inside join metal bolt, rely on metal nuts to expand, play the effect of fixing object, and efficiently solve two big defects of setscrew.The power of expanding metal nut is inside distending, it is not easy to damage is by swollen body.Screw can freely design, and matches with fixing object, does not affect outward appearance, it might even be possible to plays the effect beautified.Bolt-type expansion nut can be used for industry, building industry etc., and all such as marble, granite, construction wall, body of cement etc., can not serve as tapping nut, play fastening effect on the solid material of tapping link, safe and reliable, and install simple, convenient.
Accompanying drawing explanation
The central shaft sectional view of Fig. 1 and Fig. 2 bolt-type expansion nut respectively and right view；
Fig. 3 and Fig. 4 inserts central shaft sectional view and the right view of metal taper pin respectively.
Wherein, 1-metal nuts, 2-metal taper pin, 3-otch.
Detailed description of the invention
Below in conjunction with the accompanying drawings, embodiment is elaborated.
The utility model proposes a kind of bolt-type expansion nut, as shown in figures 1-4, it is made up of metal nuts 1, metal taper pin 2, having the screw thread supporting with screw in metal nuts first half, metal nuts is latter half of has a plurality of otch 3 parallel with axle, and metal cone pin-shaped shape is latter half of with size and metal nuts supporting, metal taper pin inserts metal nuts, Gu timing screw is by withstanding metal taper pin, makes metal nuts lower end distending, reach fixing effect.
Described metal nuts Front-end Design becomes to extend out the conical surface, increases and screw or the contact surface of packing ring.
Described kerf is strip rectangle, quantity 2～8.
Described metal nuts is shaped as strip cylinder.
Described metal taper pin is strip Rotary-table.
Bolt-type expansion nut is that metal nuts is carried out special handling, sets taper hole, be equipped with corresponding metal taper pin in metal nuts latter half, metal nuts end carries out the otch of a vertical and one horizontal, beneficially metal nuts and expands.During installation, first boring satisfactory hole on body of wall or other solid, metal nuts put into, then inserted by metal taper pin, finally insert screws into, screw have to withstand taper pin, and tightens screw, makes metal nuts lower end distending as far as possible, reaches fixing effect.Owing to the power of expansion nut is inside distending, it is not easy to damage is by swollen body.Metal nuts, metal taper pin and the size of screw, length can according to the actual requirements depending on.Screw can freely design, and matches with fixing object, does not affect outward appearance, it might even be possible to plays the effect beautified.
This embodiment is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
