Description
Technical field
The present invention relates to building field, and in particular to a kind of fast disassembly type swell fixture.
Background technology
Swell fixture is very common in building field, is often used for installing the objects such as various furred ceilings, street lamp, its primary structure
For the body of screw, the expansion tube being sheathed on outside the body of screw, and the nut composition being threaded onto on the body of screw, body of screw one end is provided with swollen
Swollen head, after being punched on wall, swell fixture is loaded into wall, make nut pull the body of screw expanding by rotating nuts
Inner axial tube moves, and then makes expansion-head dilating expansion pipe, the body of screw is securely fastened on wall, then unclamps nut, fills
Enter to need to be attached to article (such as street lamp, shelf) on wall, therefore just need repeatedly to screw nut, cause to dismount not
Just.
The content of the invention
Based on above mentioned problem, present invention aims at provide a kind of simple in construction, convenient disassembly, the fast disassembly type of fixation
Swell fixture.
For problem above, there is provided following technical scheme：A kind of fast disassembly type swell fixture, including screw, the screw
One end is provided with back taper expansion-head, is cased with expansion tube outside the screw, the expansion tube is set towards the outer wall of expansion-head one end
There are some expansion slots, the screw is provided with external screw thread relative to one end of expansion-head；The external screw thread is provided with removable convex
Wheel handle, is provided with pad between the cam handle and expansion tube, the pad includes metallic matrix, the metallic matrix direction
The one side of cam handle is provided with from profit layer, described that the circular arc mating surface being adapted with cam handle bias face is provided with from profit layer.
In said structure, by the way that cam handle is attached on swell fixture, made using the eccentric center principle of cam handle swollen
Swollen screw realizes Quick Release, and eliminate conventional expanded screw needs spanner to carry out locking to nut to make expansion tube swollen when installing and expanding
It is swollen, the later stage need again by spanner dismantle nut, further need to object to be mounted be installed on screw after locked by spanner
The cumbersome formality of tight nut；Due to consideration that cam handle is to be pressed on pad to realize contracting locking using cam surface in locking,
Therefore needs set metallic matrix on pad and from profit layers, the dispersible axial lock clamp force of metallic matrix, can be reduced from profit layer convex
Friction when wheel handle is locked.
The present invention is further arranged to, and the layer of profit certainly is teflon gasket.
In said structure, polytetrafluoroethylene (PTFE) has self-lubricity, and friction during cam handle locking can be greatly reduced.
The present invention is further arranged to, and the expansion tube is provided with one section of expansion slot, and its outer wall is tapered, and its diameter is towards swollen
Swollen head direction is gradually reduced.
In said structure, it can ensure that expansion tube its expansive force and swell diameter in expansion show one to greatest extent
Linear change, make expansion-head completely into that still expansion tube can be made to continue to expand after expansion tube, compared to existing swell fixture,
Its range of expansion is only before expansion-head is completely into expansion tube, and after expansion-head enters expansion tube, and its swell diameter is immediately
Stop.
The present invention is further arranged to, and the diameter at the expansion pipe outer wall minimum footpath is equal with expansion-head maximum diameter.
In said structure, it can effectively ensure that expansion-head forms enough range of expansion when entering expansion tube, and can is filling
When entering mounting hole, expansion tube is guided to enter mounting hole by expansion-head.
Beneficial effects of the present invention：Overall structure is simple, without spanner during installation, is applicable to the occasion often dismounted,
Because conventional expanded screw relies on nut check, thread abrasion can be caused under long-term dismounting, and the present invention passes through cam handle
Tightened, cam handle need to only be screwed slightly early stage with bolt, then pull cam handle carry out it is locked, use the longevity
Life is high.

Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
With reference to figure 1, a kind of fast disassembly type swell fixture as shown in Figure 1, including screw 10, described one end of screw 10 is provided with
The expansion-head 11 of taper, expansion tube 20, outer wall of the expansion tube 20 towards the one end of expansion-head 11 are cased with outside the screw 10
Provided with some expansion slots 21, the screw 10 is provided with external screw thread 12 relative to one end of expansion-head 11；Set on the external screw thread 12
There is removable cam handle 30, pad 31 is provided between the cam handle 30 and expansion tube 20, the pad 31 includes gold
Belong to matrix 311, the one side of the metallic matrix 311 towards cam handle 30 is provided with from profit layer 312, described to be set from profit layer 312
There is the circular arc mating surface 213 being adapted with 30 eccentric face of cam handle.
In said structure, by the way that existing cam handle 30 is attached on swell fixture, the inclined of cam handle 30 is utilized
Heart principle makes swell fixture realize Quick Release, and eliminate conventional expanded screw needs spanner to lock nut when installing and expanding
Expand expansion tube 20, the later stage need again by spanner dismantle nut, further need to object to be mounted be installed on screw 10
Pass through the cumbersome formality of spanner locking nut after upper；Due to consideration that cam handle 30 is to be pressed on pad using cam surface in locking
Contracting locking is realized on piece 31, it is therefore desirable to metallic matrix 311 is set on pad 31 and can be divided from profit layer 312, metallic matrix 311
Axial lock clamp force is dissipated, from the friction moistened when layer 312 can reduce the locking of cam handle 30.
In the present embodiment, the layer 312 of profit certainly is teflon gasket.
In said structure, polytetrafluoroethylene (PTFE) has self-lubricity, and friction when cam handle 30 is locked can be greatly reduced.
In the present embodiment, the expansion tube 20 is provided with one section of expansion slot 21, and its outer wall is tapered, and its diameter is towards expansion-head
11 directions are gradually reduced.
In said structure, it can ensure that expansion tube 20 its expansive force and swell diameter in expansion show one to greatest extent
Individual linear change, make expansion-head 11 completely into that still expansion tube 20 can be made to continue to expand after expansion tube 20, compared to existing
Swell fixture, its range of expansion only before expansion-head 11 is completely into expansion tube 20, and when expansion-head 20 enter expansion tube after,
Its swell diameter stops immediately.
In the present embodiment, diameter of the outer wall of expansion tube 20 most at path is equal with the maximum diameter of expansion-head 11.
In said structure, it can effectively ensure that expansion-head 11 forms enough range of expansion, and can when entering expansion tube 20
When loading mounting hole, expansion tube 20 is guided to enter mounting hole by expansion-head 11.
Beneficial effects of the present invention：Overall structure is simple, without spanner during installation, is applicable to the occasion often dismounted,
Because conventional expanded screw relies on nut check, thread abrasion can be caused under long-term dismounting, and the present invention passes through cam handle
30 are tightened, cam handle 30 need to only be screwed slightly early stage with bolt 10, then pull cam handle 30 carry out it is locked i.e.
Can, service life is high.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and modification can also be made, above-mentioned hypothesis these
Improvement and modification also should be regarded as protection scope of the present invention.
