Description
Technical field
This utility model is related to a kind of readily removable reusable setscrew.
Background technology
The setscrew bought on the market at present is difficult to take out once being arranged in building or concrete, needs by which
Its instrument and it is difficult to take out, that is, enables to take out and can also deform or damage, it is impossible to be normal to use, causes the wasting of resources.The present invention can
Problem above is conveniently broken off relations effectively, if thinking to split out after installation again, is easily removed, and any portion of setscrew will not be destroyed
Position, can repeatedly use.
The setscrew that can have been bought in the market typically has：Common money setscrew, such screw are once installed and used
Afterwards, basically can not take out, the method typically taken is to slice off to expose part beyond matrix face or using hammer using polisher
Son is pounded as in hole.
The criteria classification of setscrew：Setscrew generally can be divided into：Hit core pattern bolt, screw type expansion bolt, sleeve pipe
Reinforced expansion bolt, thimble tube expansion bolt, interior urgent type expansion bolt, outer urgent type expansion bolt, chemical bolt, elevator expansion
Bolt etc.
Dismountable upset bolt substantially has three kinds on the market：A kinds add a raised part outside expansion tube, need to tear open
Except when the raised part of expansion tube need to be prized with crowbar, realize the dismounting of screw.Have the disadvantage when the raised part of expansion tube with
Metope is adjacent to rear crowbar and cannot operate.B kinds are the expansion tubes being combined into by three sections of jurisdiction, when needing to remove, are pulled out with pliers piecewise
Go out expansion tube, finally extracting pull bar, reaching the purpose of dismounting.The shortcoming of this kind of dismountable upset bolt is when in hole
Too after depth, pliers cannot clip to section of jurisdiction, there is dead angle, even and if remove cannot also reuse, waste of resource.C kinds are removable
The i.e. interior urgent type expansion bolt of expansion bolt, when need to remove, screw of directly back-outing, although bolt can be reused but nut and expansion
Pipe is but always remained in hole, equally causes resource serious waste.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of readily removable reusable setscrew.
The technical scheme taken by this utility model solution above-mentioned technical problem is as follows：
A kind of readily removable reusable setscrew, including：Bolt（5）, the bolt（5）Bottom it is tapered, top
Portion is helicitic texture, and is set to stressed member in top；Expansion tube is arranged with the bolt, and is had in expansion tube again
Female thread（6）, meanwhile, the bolt（5）Top be provided with flat shim again（4）And nut（2）, spring is provided between the two
Pad（3）.
Preferably, it is described for removing when to state rotation stressed member be " one " font projection or " mouth " in spanner cocker residence
Font projection.
The present invention compared with prior art, with simple structure, low cost of manufacture, easy accessibility, understands at a glance, does not damage
Expansion bolt, back and forth can be used again.Economize on resources, environmental protection.
Other features and advantages of the utility model will be illustrated in the following description, also, operation principle is from explanation
Become apparent in book, or understood by implementing this utility model technology.The purpose of this utility model and other advantages
Can realize and obtain by specifically noted structure in the description, claims and accompanying drawing write.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is described in detail, so that above-mentioned advantage of the present utility model is more
Clearly.
Fig. 1 is the combining structure schematic diagram of the readily removable reusable setscrew of this utility model；
Fig. 2 is the decomposition texture schematic diagram of the readily removable reusable setscrew of this utility model.
Specific embodiment
This utility model is described in detail with reference to specific embodiment.
As illustrated in fig. 1 and 2, a kind of readily removable reusable setscrew, including：Bolt（5）, the bolt（5）'s
Bottom is tapered, and top is helicitic texture, and is set to " one " font projection or " mouth " font projection in top, for removing
When spanner may be stuck in rotation stressed member herein（1）；Expansion tube is arranged with the bolt, and there is interior spiral shell again in expansion tube
Stricture of vagina（6）, meanwhile, the bolt（5）Top be provided with flat shim again（4）And nut（2）, spring shim is provided between the two
（3）.
Preferably, it is described for removing when to state rotation stressed member be " one " font projection or " mouth " in spanner cocker residence
Font projection.
The present invention compared with prior art, with simple structure, low cost of manufacture, easy accessibility, understands at a glance, does not damage
Any part of expansion bolt, back and forth can be used again.Economize on resources, environmental protection.
Wherein, operation principle of the present utility model is as follows：
When installing as common setscrew, with the suitable size of electric hammer drill one and depth on metope
Hole, by setscrew patchhole, tightens the nut on pull bar with spanner, broken to match somebody with somebody the conical section and expansion tube of stud base
Expansion is closed, installation process is completed.When if desired removing, by the nut on bolt with spanner torsion, spring shim and plain cushion are taken out
Piece, rapping bolt makes its pyramidal portion exit expansion tube, and now the screw thread on bolt is contacted and matched somebody with somebody with the female thread on expansion tube
Closing, torsion bolt head " one " font or " mouth " font projection stress point being blocked with spanner, bolt is torqued into expansion inside pipe wall this moment
In screw thread, as the bottom hole that stud base pushes up body of wall cannot be shunk back again, expansion tube now is in bolt rotating reactive force
In the presence of, it is pushed out outside hole, is just easy to extract bolt after extracting expansion tube, the loose mail being pulled out again can be after reconfiguring again
New Reusability.
The key point of the present invention has：1. it is to increase screw thread in expansion tube inwall, makes screw thread of the screw rod in rollback with bolt
Contact and coordinate.2. be bolt head be provided with " one " font or " mouth " font rotation stress point, so as to remove when spanner
May be stuck in and use.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art
For, which still can be modified to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc.,
Should be included within protection domain of the present utility model.
