Abstract
The utility model relates to a butterfly-shaped self-opening screw nut, which is composed of butterfly-shaped blades, a screw nut, both sides of which are provided with rotating shafts, and a tension spring, wherein, the screw nut which is installed in the butterfly-shaped blades through the rotating shafts at both sides can rotate around the rotating shafts; the tension spring is sheathed on a rotating shaft on one side, and two butterfly-shaped blades are opened by the tension force of the tension spring. After a screw bolt is screwed into the screw nut, the butterfly-shaped blades which are closed by external force are pushed into a perforated hollow wall, and the blades are opened when entering the hollow position. Then the screw bolt is rotated, the blades driven by the screw nut are tightly contacted with the inner wall of the hollow wall, and the tightening process is completed. The utility model has the advantages of unique structure and convenient operation. The utility model which can be matched with a standard screw bolt is particularly suitable for fastening, hanging and connecting process on the surface of a hollow object.
Description
The utility model belongs to a kind of body of wall fastening piece, particularly a kind of fastening butterfly self-opening nut that articulates of hollow metope that is used for.
The general swell fixture that adopts was inserted swell fixture when present stage was installed object on body of wall or ceiling board after body of wall bores sky, and swivel nut draws nut outward, leaned on the cone of portion to make casing expandable, realized with body of wall fastening.Solid wall and hollow wall are not always the case.But the nut of this swell fixture is special, can not be general with master serew, and the general body of wall in fixing simultaneously back also leaves an end nut outward, and is neither attractive in appearance, inconvenient again when object is installed.For hollow wall, the using effect of general swell fixture is not as solid wall in addition.
The purpose of this utility model provides a kind of novel butterfly self-opening nut, and it is used for the object of hollow wall installs, and overcomes the shortcoming of existing swell fixture.
The purpose of this utility model realizes in the following manner: a kind of butterfly self-opening nut, the object that is used for hollow wall is installed, the nut and the tension spring that are had rotating shaft by two butterfly blades, both sides are formed, nut is installed in the butterfly blade by the both sides rotating shaft, can rotate around the axis, tension spring is sleeved in the rotating shaft on one side, and two butterfly blades are opened.Like this, behind a nut precession nut, use external force to make butterfly blade closure, push in the hollow wall that has punched, when whole blade advanced hollow position, the elastic force of tension spring opened two blades.Rotate nut this moment again, and blade is tight obedient hollow wall inwall under the drive of nut, finishes fastening action.
This butterfly self-opening nut structure uniqueness, easy to use, be used with the standard nut, be particularly suitable for doing fastening articulating on the incavation surface, can replace the existing application of swell fixture on hollow wall, be a kind of novel body of wall fastening piece.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the Facad structure schematic representation of this butterfly self-opening nut.
Fig. 2 is the structural representation of looking up of this butterfly self-opening nut.
Fig. 3 is the schematic representation of this butterfly self-opening nut when being installed on the body of wall.
As illustrated in fig. 1 and 2, nut 2 both sides have rotating shaft 4, are installed in the butterfly blade 1 by both sides rotating shaft 4, and nut 2 can 4 rotate around the shaft.One side of rotating shaft 4 is set with tension spring 3, and two legs of tension spring 3 prop up the inner face of two blades, and the butterfly blade is opened.
With a nut 6 precession nuts 3, make butterfly blade 1 closure during use, push in the hollow wall 7 that has punched with external force.When whole blade 1 was pushed into hollow position, the elastic force of tension spring 3 opened two blades.Rotate nut 6 this moment again, because outer wall surface has the support 8 that object is installed to block nut, nut 2 drives blade 1 and compresses to hollow wall 7 inwalls, realizes fastening the articulating on hollow wall surface.
The butterfly blade skids at interior metope when preventing that nut from screwing, and the bottom of blade 1 is provided with anti-skidding tooth 5.
Claims (2)
1. butterfly self-opening nut, the object that is used for hollow wall is installed, it is characterized in that this butterfly self-opening nut is made up of nut and tension spring that two butterfly blades, both sides have rotating shaft, nut is installed in the butterfly blade by the both sides rotating shaft, can rotate around the axis, tension spring is sleeved in the rotating shaft on one side, and two legs prop up the inner face of two blades, and two butterfly blades are opened.
2. butterfly self-opening nut according to claim 1 is characterized in that the bottom of blade is provided with anti-skidding tooth.
