Abstract
The utility model discloses an anti-theft nut and a dedicated sleeve tool thereof. In the utility model, the shape of a nut with internal threads is manufactured into a cylindrical nut; when the cylindrical nut is tightly connected with a bolt, the bolt is firstly provided with a gasket cover with a cover, the cylindrical nut is then connected on the bolt through threads, the cylindrical nut is tightly screwed on the bolt through a dedicated sleeve tool with a one-way roller pin bearing, so that the cylindrical nut can tightly press the gasket cover, and can be covered by the cover of the gasket cover; and when the cylindrical nut needs to be loosened, the dedicated sleeve tool with another one-way roller pin bearing with a different rotating direction extends into the internal cover hole of the gasket cover to be sheathed on the cylindrical nut, and then, the cylindrical nut can be loosened. The utility model has the advantages that the nut is not easy to steal, the anti-theft effect is good, the performance is reliable, and the installation, maintenance and disassembly are convenient.
Description
Technical field
The utility model relates to a kind of anti-theft nut and socket wrench specially adapted for it instrument thereof, belongs 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 purpose of this utility model is: a kind of good anti-theft effect is provided and is convenient to anti-theft nut and the socket wrench specially adapted for it instrument thereof that the maintenance man removes and installs, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of anti-theft nut of the present utility model, comprise the nut that is provided with internal thread, and 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 utility model 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 utility model 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 utility model can only be tightened or open by cylindrical anti-theft nut socket wrench specially adapted for it instrument of the present utility model, cylindrical anti-theft nut socket wrench specially adapted for it instrument of the present utility model 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 utility model compared with prior art, the utility model 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.
Description of drawings
