Description
Technical field
The present invention relates to a kind of expansion bolt and its mounting and dismounting methods, refer specifically to readily removable except formula expansion bolt and its assembly and disassembly side
Method.
Background technology
Currently, common expansion bolt is by the screw rod with expansion-head, the sleeve equipped with joint-cutting, nut and gasket etc. in the market
Parts form.Installation method be by turning nut or screw rod, expansion-head being made to enter sleeve, by sleeve from notch distending, into
And expansion bolt is made to be fixed among the hole being drilled in advance.
Expansion bolt is primarily present two problems in use.First, screw rod, nut are easy to turn together when mounted
It is dynamic, and since expansion bolt is mounted in hole, it is difficult to control causes installation inconvenient, shadow in turn there is a phenomenon where that can not fasten
Ring the use scope of expansion bolt；Second is that expansion bolt removes difficulty, the expansion bolt discarded after some uses often protrudes
It on metope or ground, is difficult to remove in the case where not destroying mounting surface, that is, influences beauty, while also resulting in subsequent construction difficulty
And form security risk.
Invention content
The present invention provides a kind of readily removable except formula expansion bolt and its mounting and dismounting method, it is therefore an objective to expansion bolt be overcome to install
The problem of journey bolt and nut rotates together phenomenon and is difficult to remove.
To achieve the above object, the readily removable formula expansion bolt that removes provided by the invention is made of screw rod, sleeve and assembly and disassembly nut.
Affiliated screw rod one end is equipped with the expansion-head with taper, and the screw rod body of rod has screw thread, on the screw rod of expansion-head one end
Be provided with several steel rings, the steel ring by floor with screw rod is concentric is connected, steel ring outer diameter is slightly less than expansion-head maximum gauge, interior
Diameter is slightly larger than sleeve diameter；The number of ribs, position are corresponding with the quantity of sleeve upper cut and position, and the thickness of floor omits
Less than the kerf width of sleeve.
The sleeve top is provided with male adapter, forms articulation with the female adapter of assembly and disassembly nut lower end so that set
Cylinder is connected with assembly and disassembly nut, and can coaxial rotating；Sleeve nut is fixed on the sleeve below articulation；Sleeve tail end
Equipped with multiple notch, aforementioned floor, which corresponds to, to be inserted into notch.
The assembly and disassembly nut is installed on screw tip, and assembly and disassembly nut lower part is equipped with female adapter, with the sleeve top
Male adapter is connected.
It is described readily removable except formula expansion bolt by designing above, realize that rotation assembly and disassembly nut can be with moving sleeve along screw shaft
To movement, interacted with floor by the notch on sleeve so that sleeve and screw rod can not send relative rotation.
Readily removable dress except formula expansion bolt of the present invention/tear method open is as follows：
When 1, installing, the readily removable formula expansion bolt that removes is inserted into the hole that mounting surface is drilled, with spanner fixes sleeve
Nut assembles and disassembles nut with another spanner precession, screw rod is made gradually to be screwed out to outside hole, the expansion-head and steel ring on screw rod
Under effect, sleeve tail end is gradually tilted along notch, and then is realized readily removable except formula expansion bolt is fixed in hole；
When 2, removing, with spanner fixes sleeve nut, assembly and disassembly nut is screwed out with another spanner, makes screw rod to inside hole
Gradual precession, under the squeezing action of steel ring, origin-location is gradually restored in the raised portion of sleeve tail end, so that bolt is released solid
It is fixed, and then take out；
The present invention will be by that will assemble and disassemble nut and sleeve is connected with articulation so that in assembly and disassembly nut spinning in and out process
With screw rod axial relative movement occurs for middle band moving sleeve；By the way that steel ring and floor is arranged in screw rod tail end so that sleeve and screw rod
It can not relatively rotate；The mounting and dismounting method by precession or is screwed out assembly and disassembly nut, is made with sleeve nut's fixes sleeve position
It obtains sleeve to occur to tilt or reset along notch under the action of expansion-head and steel ring, and then realizes the installation or dismounting of bolt.
Compared with the prior art, the present invention has the following advantages：
1, existing expansion bolt is overcome during the installation process, nut is easy that screw rod is driven to rotate together, can not precession
Problem；
2, the problem of existing expansion bolt is difficult to remove is overcome.

Specific implementation mode
The present invention is further illustrated with a specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, the present embodiment is made of screw rod 1, sleeve 2, assembly and disassembly nut 3；
As depicted in figs. 1 and 2,1 tail end of the screw rod is equipped with the expansion-head with dimension, and 1 shaft of screw rod has screw thread, in screw rod
1 shaft tail portion is arranged at expansion-head there are two steel ring 1.1, and each steel ring 1.1 passes through 4 floors 1.2 and 1 coaxial phase of screw rod
Even；
As shown in figures 1 and 3, the outer diameter of steel ring 1.1 is slightly less than expansion-head maximum gauge, and internal diameter is slightly larger than 2 diameter of sleeve；
As shown in figure 3, assembly and disassembly nut 3 has female adapter 3.1,2 upper end of sleeve is equipped with male adapter 2.1, and concave surface connects
First 3.1 form articulation with male adapter 2.1 so that assembly and disassembly nut 3 can be rotated coaxially with sleeve 2, and sleeve nut 2.2 fixes
In on 2 outer wall of sleeve close to 2.1 lower part of male adapter；
As shown in Figure 1 and Figure 4,2 tail end of sleeve is equipped with 4 notch 2.3, and 2.3 width of notch is slightly larger than the thickness of floor 1.2
Degree, 2.3 quantity of notch and position are corresponding with floor 1.2, so that 4 floors 1.2 is corresponded to and are inserted into notch 2.3, so that set
Cylinder 2 is between steel ring 1.1 and screw rod 1.
The installation method of the present embodiment is as shown in figure 5, with spanner fixes sleeve nut 2.2, while nut 3 is assembled and disassembled in precession,
So that 1 relative sleeve 2 of screw rod screws out outward, and then under the effect of the expansion-head of 1 rear end of screw rod, sleeve 2 is tilted along notch, is realized
The entirety of bolt is fixed；
As shown in fig. 6, when the present embodiment is removed, first with spanner fixes sleeve nut 2.2 so that 1 relative sleeve 2 of screw rod
Inside precession, and then under the action of steel ring 1.1, the raised portion of sleeve 2 is pushed back into origin-location, realizes the dismounting of bolt.
Assembly and disassembly nut 3 is connected by the present invention in the form of articulation with sleeve 2, and nut 3 is assembled and disassembled with moving sleeve 2 with spinning in and out
Along 1 relative motion of screw rod, sleeve 2 is limited with floor 1.2 and is not relatively rotated with screw rod 1.It is solid with spanner in assembling and dissembling process
Determine 2 position of sleeve, under the action of expansion-head and steel ring 1.1, so that sleeve 2 is occurred to tilt and is resetted along notch, realize bolt
Assembly and disassembly.
The present invention overcomes existing expansion bolt nuts and screw rod to be easy to happen the problem of common rotation violates precession, simultaneously
Expansion bolt is realized to be easy to remove.
