Abstract
The invention discloses a method for preventing a fastening nut from being stolen, an anti-theft nut and a special sleeve tool. A nut with internal threads is made into a cylindrical nut; when the cylindrical nut and a bolt are connected and fastened together, a washer sleeve with a cover sleeve is arranged on the bolt, and the cylindrical nut is connected to the bolt through the threads and is screwed on the bolt through the special sleeve tool with a one-way needle bearing, so that the cylindrical nut tightly presses the washer sleeve and is covered by the cover sleeve on the washer sleeve; and when the nut is needed to be loosened, another special sleeve tool with the one-way needle bearing in a different rotating direction stretches into an inner hole of the cover sleeve on the washer sleeve and is sleeved on the nut to loosen the nut. The invention has the advantages that: the anti-theft nut is difficult to steal, has a good anti-theft effect and reliable performance, and is convenient to install, maintain and disassemble.
Description
Technical field
The present invention relates to a kind of tightening nut that prevents by the method for pirate of the open and anti-theft nut and socket wrench specially adapted for it instrument, belong to technical field of fastening.
Background technique
On the Infrastructure of communication, electric power, railway, it is fastening to use screw, nut to carry out in a large number, because common nut is easy to turn on, so the theft of screw, nut is very rampant.Chinese patent 200420085065.2 discloses a kind of anti-theft nut and special sleeve spanner, and disclosed anti-theft nut adopts the conical outside, and at the arranged outside convex shape rib plate, the inboard positioning groove that mates with convex shape rib plate that is provided with of socket wrench.The claimant finds that the nut of said structure has 2 defectives: the one, and the convex shape rib plate in the nut outside provides Point of Strength, can withstand convex shape rib plate with crooked chisel, by knocking crooked chisel, with nut shake pine, turns on nut then; The 2nd, nut directly is exposed, and can by force nut be turned on by plumbing combination pliers, spanner etc.More existing anti-theft nuts adopt the structure that can not unclamp after tightening, though can be antitheft, can not change the fastening facility that damages, for the situation that needs periodical repair, replacing, also practical inadequately.Therefore, the using effect of existing anti-theft nut still is not ideal enough.
Summary of the invention
The objective of the invention is to: what a kind of good anti-theft effect is provided and is convenient to that the maintenance man removes and installs prevents that tightening nut is by the method for pirate of the open and anti-theft nut and socket wrench specially adapted for it instrument, to overcome the deficiencies in the prior art.
The present invention constitutes like this: a kind of tightening nut that prevents of the present invention is the nut that the shape fabricating that will be provided with the nut of internal thread becomes cylindrical shape by the method for pirate of the open, be connected with bolt when tightening together at nut this cylindrical shape, on bolt, adorn earlier a gasket sleeve that is provided with the enclosure, then with the nut of cylindrical shape by being threaded on the bolt, and by the socket wrench specially adapted for it instrument that is provided with unidirectional needle bearing cylindrical nut is tightened on the bolt, make the nut of cylindrical shape gasket sleeve be compressed and make the nut of this cylindrical shape covered by the enclosure on the gasket sleeve; When needs unclamp nut, the socket wrench specially adapted for it instrument of the unidirectional needle bearing by being provided with another different sense of rotation puts in the enclosure endoporus on the gasket sleeve and is enclosed within on the nut and nut is unclamped, and promptly is enclosed within the characteristics that can only rotate in one direction on the columniform nut and can not rotate in the opposite direction with nut screwing clamping or unclamp by the unidirectional needle bearing in the socket wrench specially adapted for it instrument; Can reach in this way and prevent that tightening nut is by the purpose of pirate of the open.
In said method, the surface configuration of the bolt end of the bolt that is connected with the nut of cylindrical shape is a spherical shape, and is provided with the anti-slip fixture block in the joint of the screw rod of bolt end and bolt.
Be used for of the present invention a kind of anti-theft nut of said method, comprise the nut that is provided with internal thread, this nut outer is shaped as ganoid cylinder form.
All be provided with the guiding conical surface at above-mentioned columniform nut two ends.
Be provided with the gasket sleeve that nut can be covered outside above-mentioned nut, gasket sleeve is made up of the packing ring that is provided with bolt hole and the enclosure, and the enclosure and packing ring are fixing as a whole.
The endoporus of the enclosure of above-mentioned gasket sleeve is a straight hole, and the outside of the enclosure is the circular cone cylinder, and the angle of this circular cone cylinder and central axis is 3 °～45 °.
Be used for the of the present invention a kind of cylindrical anti-theft nut socket wrench specially adapted for it instrument of said method, comprise sleeve, the unidirectional needle bearing that can be enclosed within on the columniform nut is arranged at the port internal fixation of sleeve.
In the port of the two ends of above-mentioned sleeve, all be fixed with a unidirectional needle bearing that can be enclosed within on the columniform nut respectively, and on sleeve, be provided with the extension lever hole that can penetrate extension lever.
Two the needle bearings that unidirectional needle bearing be same inner diameter of said fixing in the port of sleeve two ends, and the direction of rotation of these two unidirectional needle bearings.
Owing to adopted technique scheme, the present invention is by being made into cylindrical shape with nut, and nut is being connected with bolt when tightening, adopt the gasket sleeve of centrum formula that nut is entangled, so both can prevent from nut, to provide Point of Strength, can prevent again that nut or gasket sleeve from being impacted, being turned on by instruments such as pipe tongs or conventional spanner by crooked chisel.Anti-theft nut of the present invention can only be tightened or open by cylindrical anti-theft nut socket wrench specially adapted for it instrument of the present invention, cylindrical anti-theft nut socket wrench specially adapted for it instrument of the present invention has the unidirectional needle bearing that can be enclosed within on the columniform nut at the port internal fixation of sleeve, the internal diameter of this unidirectional needle bearing and the body diameter of cylindrical anti-theft nut can be according to different use clients, be made into the nonstandard size of different size, have only the client who has grasped this cylindrical anti-theft nut socket wrench specially adapted for it instrument just can tighten and unclamp anti-theft nut like this.And the anti-theft nut socket wrench specially adapted for it instrument that each client grasped can only be used to open or tighten this client's anti-theft nut, and not be suitable for the anti-theft nut of tightening or open other clients.So, the present invention compared with prior art, the present invention not only has the advantage of the pirate of the open of being not easy, good anti-theft effect, reliable performance, but also has all advantages easily of installation, maintenance, dismounting.
