Description
Technical field
The present invention relates to bolt arrangement technical field, particularly a kind of anti-theft bolt and its special dismantling device.
Background technology
Hex(agonal)screw or nut are widely used in communal facility as fastener, for example electric power, communication, road, guardrail,
Bridge, steel tower etc., due to common hex(agonal)screw or nut, the design of its hexagonal extremely convenient in installation and removal is used
Spanner can be backed out easily, also due to this convenience so that the theftproof performance of hex(agonal)screw or nut is poor, to above-mentioned facility band
Carry out very big unsafe factor, substantial amounts of property loss can have been caused, therefore, a kind of theftproof performance screw high or nut turn into
It is required.
The content of the invention
Shortcoming it is an object of the invention to overcome prior art, there is provided a kind of anti-theft bolt of theftproof performance high and its specially
Use dismantling device.
The purpose of the present invention is achieved through the following technical solutions：A kind of anti-theft bolt, including screw rod and nut, it is described
The first groove of cylinder type is offered on the top surface of nut, the bottom land of the first groove of cylinder type is provided with clamping joint, positioned at card
Capping is provided with by screw thread in first groove on joint top, it is what clamping joint was stepped down that the bottom surface of described capping is provided with and uses
Second groove, is provided with the 3rd groove of cylinder type on the top surface of capping, is provided with the cell wall of the 3rd groove and prolonged vertically
Stretch, in the 4th groove of bar shaped.
The 3rd described groove is used for grafting dismantling device.
The 4th described 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, pacify on the top surface of barrel-type casing
Equipped with an adjusting nut, the excircle rotation of adjusting nut is installed on the top surface of barrel-type casing, is provided with adjusting nut
One drive screw, the lower end of drive screw is stretched into inside barrel-type casing, and the lower end of drive screw is hinged with and anti-theft bolt
The telescopic arm of the 4th fit depressions, is provided with bar hole in the middle part of telescopic arm, bar hole be fixedly arranged on barrel-type casing bottom surface
Branch it is column articulated, the side wall of barrel-type casing is provided with the resigning hole passed through for telescopic arm.
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 configuration schematic diagram of the invention.
In figure, the grooves of 1- first, 2- clamping joints, 3- cappings, the grooves of 4- second, the grooves of 5- the 3rd, the grooves of 6- the 4th, 7-
Shape housing, 8- adjusting nuts, 9- drive screws, 10- telescopic arms, 11- bar holes, 12- branch is column articulated.
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, including screw rod and nut, the of cylinder type is offered on the top surface of described nut
One groove, the bottom land of the first groove of cylinder type is provided with clamping joint, and screw thread is passed through in first groove on clamping joint top
Capping is installed, the bottom surface of described capping is provided with the second groove for being clamping joint resigning, is provided with the top surface of capping
In the 3rd groove of cylinder type, be provided with the cell wall of the 3rd groove axially extend, in the 4th groove of bar shaped.
The 3rd described groove is used for grafting dismantling device.
The 4th described 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, pacify on the top surface of barrel-type casing
Equipped with an adjusting nut, the excircle rotation of adjusting nut is installed on the top surface of barrel-type casing, is provided with adjusting nut
One drive screw, the lower end of drive screw is stretched into inside barrel-type casing, and the lower end of drive screw is hinged with and anti-theft bolt
The telescopic arm of the 4th fit depressions, is provided with bar hole in the middle part of telescopic arm, bar hole be fixedly arranged on barrel-type casing bottom surface
Branch it is column articulated, the side wall of barrel-type casing is provided with the resigning hole passed through for telescopic arm.
As shown in Fig. 2 rotating adjusting nut, drive screw is moved downward, and drives telescopic arm to be stretched out simultaneously from barrel-type casing
Grafting enters the 4th groove of nut.So as to capping rotation can be driven by drive screw, the dismounting of capping is realized.
The present invention set in groove, groove capping, capping using special by being set on the top surface of the nut of anti-theft bolt
The structure that could be dismantled with instrument, constitutes unconventional disassembly and assembly construction, it is necessary to matched special dismantling device is opened
Capping, and then bolt is screwed by the spanner being engaged with clamping joint, considerably enhance the theftproof performance of anti-theft bolt.
