Step down the second groove, be provided with the top surface of capping axially extend, in the 3rd ring-like groove, on the cell wall of the 3rd groove
It is provided with buckling groove.
The 3rd described groove is used for grafting dismantling device.
Described buckling groove is used for clamping dismantling device.
The horizontal cross-section of described clamping joint is irregular polygon.
A kind of special dismantling device of described anti-theft bolt, including a barrel-type casing under shed, barrel-type casing
Diameter and thickness are closed with the matching size of the 3rd groove of anti-theft bolt easy to assemble, to cause that it is recessed that barrel-type casing is inserted into the 3rd
Groove simultaneously constitutes gap cooperation, and the elastic block tongue being engaged with the buckling groove of anti-theft bolt is provided with the side wall of barrel-type casing.
When using, barrel-type casing inserts the 3rd groove, and elastic block tongue is in compressive state by the cell wall extruding of the 3rd groove,
When elastic block tongue is reached at buckling groove, elastic block tongue ejecting card enters in buckling groove, and it is achievable right now to rotate barrel-type casing
The dismounting of capping, after completing dismounting, continues to be pressed downward barrel-type casing, and elastic block tongue receives the extruding of the 3rd groove cell wall, again
In compressive state, now barrel-type casing is rotated to an angle so that elastic block tongue is not located at same straight line with buckling groove, then
Barrel-type casing can easily be extracted.
The structure of described elastic block tongue includes the shoulder hole for being arranged on cylinder outer race body sidewall and radially extending, sets
In the tongue body in shoulder hole, it is arranged at the spring of tongue body rear end and positioned at spring rear side and blocks the plug of shoulder hole rear port,
The front end of tongue body is stretched out from the front port of shoulder hole, and shoulder hole forms spacing to tongue body front end.
Described tongue body includes the tongue type portion of front side and the cylindrical type portion of rear side, and tongue type portion and cylindrical type portion are integrally formed,
The lower surface in tongue type portion is that, along acclivitous lozenges from back to front, described shoulder hole includes the circular hole portion and front side of rear side
Resigning hole portion, between cylindrical type portion and circular hole portion formed gap coordinate, tongue type portion passes through from resigning hole portion.
The present invention has advantages below：
The present invention uses special tool by setting setting capping, capping in groove, groove on the top surface of the nut of anti-theft bolt
The structure that could dismantle of tool, constitutes unconventional disassembly and assembly construction, it is necessary to matched special dismantling device opening is covered,
And then bolt is screwed by the spanner being engaged with clamping joint, considerably enhance the theftproof performance of anti-theft bolt.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the mplifying structure schematic diagram in I portions in Fig. 1.
In figure, the grooves of 1- first, 2- clamping joints, 3- cappings, the grooves of 4- second, the grooves of 5- the 3rd, 6- buckling grooves, 7- tubulars
Housing, 8- shoulder holes, 9- tongue bodies, 10- springs, 11- plugs.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of anti-theft bolt easy to assemble, including screw rod and nut, cylinder is offered on the top surface of described nut
First groove of type, the bottom land of the first groove of cylinder type is provided with clamping joint, leads in first groove on clamping joint top
Cross screw thread and capping is installed, it is the second groove that clamping joint is stepped down that the bottom surface of described capping is provided with use, on the top surface of capping
Be provided with axially extend, in the 3rd ring-like groove, be provided with buckling groove on the cell wall of the 3rd groove.
The 3rd described groove is used for grafting dismantling device.
