Description
Technical field
The present invention relates to technical field of fastening, especially a kind of in the field facility such as power system and communication system
In fastenings or component with bolt with the use of anti-theft nut.
Background technology
Current bolt does not has anti-theft protection function mostly, but at some special occasions, such as the power transmission tower of power system
Deng, for preventing the destruction of lawless person, then require that bolt has anti-theft feature, devise various antitheft spiral shell for these people
Mother, as the utility model patent of Patent No. ZL200720090142.7 discloses a kind of anti-theft nut, this anti-theft nut be
The inwall of nut arranges groove, places hoodle, spring and block and carries out antitheft, have the spy that theftproof performance is good in groove
Point, but owing to it to place hoodle, spring and block in groove, so existing, loaded down with trivial details problem is installed.
Summary of the invention
Problem to be solved by this invention is to provide a kind of needle-type nut for protecting bolt, and it can solve existing
Anti-theft nut installs loaded down with trivial details problem.
In order to solve the problems referred to above, the technical solution used in the present invention is: this for protecting the needle-type nut of bolt,
Including nut, the inwall in described nut thread hole, at least provided with a spine groove, is provided with needle roller, described needle roller in described spine groove
It is inlaid in by being located at the capping at two ends in the screwed hole of described nut.In technique scheme, more specifically scheme also may be used
To be: described nut is in being respectively arranged at two ends with concave station, and two pieces of described cappings are inlaid in two ends by circlip for hole respectively
On described concave station.
Further: described nut is provided with concave station in one end, one piece of described capping is inlaid in described recessed by hole back-up ring
On platform, capping described in another block is connected with the other end of described nut.
In order to solve the problems referred to above, another technical solution used in the present invention is: include nut body, and described nut is originally
Body includes that the overcoat being provided with centre bore and the one end being inserted in this centre bore are provided with the screwed hole inner sleeve of cylinder table；Outside described
The inwall of set centre bore, at least provided with a spine groove, is provided with needle roller in described spine groove, and described needle roller is by being located at described overcoat
The capping of one end is fitted on the cylinder table of described screwed hole inner sleeve.
In technique scheme, more specifically scheme it may also is that described overcoat be respectively arranged at two ends with concave station, described
The cylinder table of screwed hole inner sleeve is contained on the concave station of described overcoat one end, and the concave station of the described overcoat other end is provided with capping.
Owing to have employed technique scheme, the present invention compared with prior art, has the beneficial effect that
1, the present invention is provided with spine groove and needle roller, clamping action occurs when bolt contacts with needle roller in spine groove, rotates clockwise spiral shell
Can be tightened by bolt during bolt, when rotating counterclockwise bolt, bolt plays the effect of locking under clamping action；Due to the present invention only
Need to put into needle roller in spine groove, so installing simple.
2, the present invention is provided with spine groove and needle roller, and clamping action occurs when screwed hole inner sleeve contacts with needle roller in spine groove, suitable
During hour hands rotating bolt, it is enclosed within screwed hole and plays the effect of locking under clamping action and bolt can be tightened.Rotate counterclockwise spiral shell
During bolt, screwed hole inner sleeve and needle roller attaching space gap in spine groove become big, and in spine groove, needle roller is freely rotatable, and clamping action stops,
Bolt dallies.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1.Fig. 2 is the top view that Fig. 1 removes capping.
Fig. 3 is the structural representation of the embodiment of the present invention 3.
Fig. 4 is the top view that Fig. 3 removes capping.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Embodiment 1
The needle-type nut for protecting bolt shown in Fig. 1 and Fig. 2, including nut 1, the inwall at nut 1 screwed hole is provided with
Three spine grooves 2, are mutually 120 degree of angles between three spine grooves 2, at each spine groove 2 built with a needle roller 3, needle roller 3 is by being located at two
The capping 5 of end is inlaid on nut 1.Nut 1 is respectively arranged at two ends with the concave station 4 of circle, and two pieces of cappings 5 are elastic by hole respectively
Back-up ring 6 is inlaid on the concave station 4 at two ends, is provided with circlip for hole 6 in the outside of capping 5, and circlip for hole 6 is embedded in two ends
The circlip for hole 6 of concave station 4 sidewall is installed in annular groove.
Embodiment 2
Be provided with concave station 4 in nut 1 one end, one piece of capping 5 is inlaid on the concave station 4 of nut 1 one end by circlip for hole 6,
Another block capping 5 is welded on the other end of nut 1；Other features are same as in Example 1.
During use, in the concave station 4 of the one side that nut 1 is put in a capping 5, needle roller 3 is put into spine groove 2, then will be another
One concave station 4 covering 5 another sides putting into nut 1, rotates clockwise bolt, at the work of needle roller 3 with the frictional force of bolt
Under with, the needle roller 3 in spine groove 2 and threaded bolt contacts spatial joint clearance become big, and needle roller 3 is free to rotate, can be tightened by bolt.When inverse
During hour hands rotating bolt, under the effect of needle roller 3 and the friction of bolt, the needle roller 3 in spine groove 2 and threaded bolt contacts spatial joint clearance
Diminishing, needle roller 3 and bolt generation clamping action, bolt is locked out.
When bolt to be taken off, the circlip for hole 6 outside capping 5 is taken off, takes out capping 5, by the rolling in spine groove 2
Pin 3 takes out, and can be exited by screw rod.Bolt can be played the effect that thrust is anti-loose by this needle-type nut.
Embodiment 3
The needle-type nut for protecting bolt as shown in Figure 3 and Figure 4, including nut body, during nut body includes being provided with
The overcoat 11 of central hole and the one end being inserted in this centre bore are provided with the screwed hole inner sleeve 10 of cylinder table 101；At overcoat 11 center
The inwall in hole is provided with three spine grooves 2, is mutually 120 degree of angles between three spine grooves 2, is provided with needle roller 3 in spine groove 2, and needle roller 3 is by setting
Capping 5 in overcoat 11 one end is fitted on the cylinder table 101 of screwed hole inner sleeve 10；Overcoat 11 be respectively arranged at two ends with concave station 4,
The cylinder table 101 of screwed hole inner sleeve 10 is contained on the concave station 4 of overcoat 11 one end, and the concave station of overcoat 11 other end is provided with capping 5.
During use, inner sleeve 10 is inserted in overcoat 11, then needle roller 3 is put into spine groove 2, the cylinder of inner sleeve 10 overlaps upper cover 5, will
Capping 5 is welded with overcoat 11.
Bolt is rotated clockwise, under the effect of needle roller 3 and the frictional force of screwed hole inner sleeve 10, needle roller 3 and screwed hole
There is clamping action in inner sleeve 10, can be tightened by bolt.When rotating counterclockwise bolt, needle roller 3 connects with screwed hole inner sleeve 10
Tactile space gap becomes big, and the needle roller 3 in spine groove 2 is freely rotatable, and clamping action stops, and screw rod dallies.
This scheme is anti theft design, bolt after being screwed into idle running action based on nut cannot again back-out, only can secondary hard
Gu use.
