Description
Technical field
The present invention relates to a kind ofly prevent that fastening piece, by the method for pirate of the open and anti-theft fastening piece and special spanner, belongs to anti-theft fastening piece technical field.
Background technique
In the Infrastructure of communication, electric power, railway, use in a large number screw, nut to carry out fastening, because common nut is easy to turn on, therefore the event that adopts plain screw, the facility of nut locking to steal is often occurred.For addressing this problem, propose in the prior art manyly to prevent that fastening piece is by the technological scheme of pirate of the open, application number as disclosed in Chinese patent literature is 2010202667407, denomination of invention is the technological scheme of " a kind of theftproof bolt with abnormal shape ", in this technological scheme, nut or bolt head are made as to frustum type structure, a part by the side of nut or bolt head is made into continuous conical surface, its remainder is made into the continuous icicle face that the plural conical surface forms, adopt so common pipe wrench just can not open this theftproof bolt with abnormal shape, and can only could open by special spanner.Although the heterotypic bolt of this structure has certain anti-theft feature, the problem that exist complex structure, make difficulty, fabricating cost is high, particularly its patent spanner adopts and the diverse structure of conventional pipe wrench, and therefore its fabricating cost is higher; And the continuous icepro cone structure adopting due to existing this heterotypic bolt, there is Ling Jiao in the joint at its conical surface and the conical surface, this icepro angular position is easy to be impacted, thereby it is loosening that bolt or nut are produced, and therefore the anti-theft effect of existing this structural fasteners neither be fine.So using effect of existing existing anti-theft fastening piece or not ideal enough.
Summary of the invention
The object of the invention is to: provide a kind of good anti-theft effect and simple in structure, fabricating cost is lower, easy to use prevents that fastening piece is by the method for pirate of the open and anti-theft fastening piece and special spanner, to overcome the deficiencies in the prior art.
The present invention is achieved in that and of the present inventionly a kind ofly prevents that fastening piece from by the method for pirate of the open being, in advance the shape fabricating of the bolt head of the bolt being made up of with bolt head screw rod in fastening piece is become to circular cone post shapes, the profile of the nut in fastening piece is also made into circular cone post shapes, then the structure shape of pipe wrench formula will be made into for tightening or open this special spanner that there is the bolt of circular cone post profile bolt head or there is the nut of circular cone post profile, simultaneously in the time making the special spanner of this pipe wrench formula, the clamp face of using it for clamping fastening piece is made into the clamp face of oblique cone face-type structural, make the oblique cone angle of this tilted conical surface identical with the cone angle of nut or bolt head circular cone post, can make like this bolt head of clamp face bolt in clamping fastening piece of tilted conical surface formula time, or in the time of clamping nut, this clamp face can fit together with the conical surface of the circular cone post profile of bolt head or nut, adopt in this way, can can only open or tighten this fastening piece that there is the bolt of circular cone post profile bolt head or there is the nut of circular cone post profile by this special spanner, prevent that fastening piece is by the object of pirate of the open thereby reach.
Of the present invention a kind of anti-theft fastening piece for said method is: the bolt that this anti-theft fastening piece comprises the nut of fastening piece and is made up of screw rod and bolt head, the profile of the bolt head of bolt and the profile of nut are circular cone post shapes.
The conical surface of circular cone post of the nut of the bolt head of above-mentioned circular cone post profile and circular cone post profile and the cone angle of horizontal plane are respectively 45 °～85 °.
At above-mentioned bolt head or/and the edge that the conical surface of the circular cone post of nut is connected with its major diameter plane is radiused edges, bolt head or/and the conical surface of the circular cone post of nut be connected with its major diameter plane by radiused edges respectively.
The radius of above-mentioned radiused edges is 4～10 millimeters.
Of the present invention a kind of special spanner for said method is, this special spanner comprises pipe wrench handle and the movable binding clip of composition pipe wrench shape, on movable binding clip, be provided with threaded stem, the threaded stem activity of movable binding clip is plugged in the mounting hole on pipe wrench handle, on the threaded stem of movable binding clip, adjusting nut is housed, pipe wrench handle determine on the moving clamp face on clamp face with at movable binding clip, be provided with tilted conical surface, and be arranged on the tilted conical surface determined on clamp face or on moving clamp face and the oblique cone angle of horizontal plane is 45 °～85 °.
Above-mentioned be arranged on determine on clamp face and moving clamp face on tilted conical surface be all the symmetrically arranged diclinic conical surface, determining to be all respectively arranged with two symmetrical tilted conical surfaces on clamp face He on moving clamp face, and these two symmetrical tilted conical surfaces are all 45 °～85 ° with the oblique cone angle of horizontal plane respectively.
Above-mentioned special spanner determine on clamp face and moving clamp face on tilted conical surface on be all provided with friction teeth.
Above-mentioned determine the clamp face that clamp face and moving clamp face are circular arc, and to determine clamp face be dome arc, moving clamp face is concave circular arc shape.
The dome radius of the above-mentioned dome arc of determining clamp face is more than or equal to the recessed circle radius of the concave circular arc shape of moving clamp face.
Owing to having adopted technique scheme, the present invention is by being made into circular cone post shapes by the bolt head of the nut in fastening piece or bolt, and the nut of this circular cone post shapes or bolt head for traditional spanner or pipe wrench without any Point of Strength, so adopting common spanner or pipe wrench just cannot be turned on, simultaneously because the nut of circular cone post shapes of the present invention or the circular cone post surface of bolt head are smooth surfaces, the icepro angular position forming without any the icicle face of plane composition, therefore the Point of Strength also not impacting, so also can not adopt the mode impacting is become flexible.Anti-theft fastening piece of the present invention can only be tightened or be opened by special spanner of the present invention, because special spanner of the present invention is special spanner, only has the client who has grasped this special spanner just can tighten and unclamp anti-theft fastening piece of the present invention.What the drive mechanism of special spanner of the present invention and operating principle adopted is the structure of pipe wrench formula of the prior art, just in the time making clamp face, slightly change, so in the time producing special spanner of the present invention, can directly adopt existing manufacturing mechanism to produce, do not need to drop into again new equipment, greatly saved production capital.Therefore, compared with prior art, the present invention not only has advantages of good anti-theft effect in the present invention, but also has the advantages such as simple in structure, making is easy, fabricating cost is low, easy to use.
