Abstract
The invention discloses an expansion bolt removal tool. The expansion bolt removal tool comprises a spanner, a screw and a support. The support is provided with supporting legs, and a support plate is arranged on the supporting legs. The screw is arranged in the center of the support plate, penetrates through the center of the support plate and is connected with the support plate through threads. The spanner is arranged at the upper end of the screw. A conical shell clamp is arranged on the side, opposite to the supporting legs, of the screw, arranged on the screw in a sleeving mode and connected to the screw through a connecting bolt. A conical sleeve is arranged on the shell clamp and can slide on the shell clamp and clamp the shell clamp. The expansion bolt removal tool is easy to operate, capable of conveniently removing expansion bolts of different sizes and high in universality, does not damage wall structures, saves labor and avoids that trouble is brought to subsequent engineering.
Description
Technical field
The present invention relates to a kind of can dismounting and follow closely in expansion bolt within the walls, the extracting tool of the expansion bolt of time saving and energy saving, highly versatile simple to operate.
Background technology
Expansion bolt is widely used in building trade, particularly requires fixed occasion at some, such as pendent lamp, air-conditioning, the installation etc. of water heater.Expansion bolt advantage is that fixing object is firm, install simple, shortcoming be install after the most quick detachable, toll breakdown and can destroy body of wall, do not remove and can bring danger and difficulty to following construction, so by design a kind of expansion bolt extracting tool, can easily by expansion bolt from removing within the walls, the most do not destroy wall body structure.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art and provide a kind of can dismounting to follow closely in expansion bolt within the walls, the extracting tool of the expansion bolt of time saving and energy saving, highly versatile simple to operate.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of expansion bolt extracting tool, including spanner, screw rod and support；Described support is provided with leg；It is provided with supporting plate on described leg；Described supporting plate is provided centrally with screw rod, and screw rod passes supporting plate center；Described screw rod uses with supporting plate threadeds；Described screw rod upper end is provided with spanner；The screw rod of leg respective side is provided with shell fastening clip；Described shell fastening clip is that conical sleeve is located on screw rod；Described shell fastening clip is connected on screw rod by attachment bolt；It is provided with tapered sleeve cylinder on described shell fastening clip；Described tapered sleeve cylinder can slide on shell fastening clip, it is possible to by shell fastening clip clamping.
Preferably, described shell fastening clip is divided into epicone folder and lower cone folder two parts；Described epicone folder and lower cone clamp ring are embraced on screw rod.
Preferably, described attachment bolt couples shell fastening clip through screw rod；And length cannot be greater than the minimum diameter of tapered sleeve cylinder.
Preferably, the end of described shell fastening clip is set to stairstepping jaws.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
A kind of expansion bolt extracting tool of the present invention program, simple to operate, convenient disassembly, various sizes of expansion bolt, highly versatile can be dismantled, do not destroy wall body structure, save manpower, it is to avoid make troubles to successive projects.

Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the cross-sectional view of a kind of expansion bolt extracting tool of the present invention；
Accompanying drawing 2 is the operating diagram of the dismounting expansion bolt of a kind of expansion bolt extracting tool of the present invention；
Wherein: 1, spanner；2, screw rod；3, support；4, shell fastening clip；5, tapered sleeve cylinder；6, attachment bolt；7, the pull bar of expansion bolt；8, the shell of expansion bolt；9, body of wall；31, leg；32, supporting plate；41, epicone folder；42, lower cone folder；43 stairstepping jaws.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
Accompanying drawing 1-2 is a kind of expansion bolt extracting tool of the present invention, including spanner 1, screw rod 2 and support 3；Described support includes leg 31；It is provided with supporting plate 32 on described leg 31；Described supporting plate 32 is provided centrally with screw rod 2, and screw rod 2 is through supporting plate 32 center；Described screw rod 2 uses with supporting plate 32 threadeds；Described screw rod 2 upper end is provided with spanner 1；The screw rod 2 of leg 31 respective side is provided with shell fastening clip 4；Described shell fastening clip 4 is located in conical sleeve on screw rod 2, and the end of described shell fastening clip 4 is set to stairstepping jaws 43；Described shell fastening clip 4 is connected on screw rod 2 by attachment bolt 6, and shell fastening clip 4 and attachment bolt 6 are all matched in clearance on radial and axial, and attachment bolt 6 is through screw rod 2；It is provided with tapered sleeve cylinder 5 on described shell fastening clip 4；Described tapered sleeve cylinder 5 can slide on shell fastening clip 4, it is possible to by shell fastening clip 4 clamping；Described shell fastening clip 4 is divided into epicone folder 41 and lower cone folder 42 two parts；Described epicone folder 41 can open certain angle up and down with lower cone folder 42；Described epicone folder 41 and lower cone folder 42 are encircled on screw rod 2；The length of described attachment bolt 6 cannot be greater than the minimum diameter of tapered sleeve cylinder 5.
When wanting to remove the expansion bolt followed closely in body of wall 9, first by 3, support and body of wall 9, screw rod is rotated by spanner 1, screw rod 2 is made to move axially, screw rod 2 is made to push down the pull bar 7 of expansion bolt, the pull bar 7 of expansion bolt is pushed back in hole, the shell 8 of expansion bolt loses expansionary force radially, it is easier to take off, at this moment stairstepping jaws 43 stretches into intracavity and clamps the shell 8 of expansion bolt, with again tapered sleeve cylinder 5 being enclosed within shell fastening clip 4, and by its clamping, now the shell 8 of expansion bolt is clamped by shell fastening clip 4, being rotated further by spanner 1 makes screw rod 2 move out, shell fastening clip 4 is driven to move out, expansion bolt is taken apart simultaneously；Epicone folder 41 and lower cone folder 42 two parts of shell fastening clip 4 can dismantle various sizes of expansion bolt, highly versatile.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
