The anti-theft nut and wrench have the advantages that the anti-theft can not be twisted by a universal wrench, and the device is not easy to steal.
Description
Technical field
The present invention relates to a kind of anti-theft nut and spanner.
Background technique
In actual life, the equipment be connected with nut by plain screw usually because nut is just screwed down by Allen wrench easily very much, causes equipment stolen, causes economic loss.
Summary of the invention
The object of this invention is to provide anti-theft nut and spanner that a kind of nut can not turn by Allen wrench.For achieving the above object, the present invention adopts following technological scheme:
A kind of anti-theft nut and spanner, be made up of nut and spanner, described nut outside is cylindrical, inside is v thread, described spanner is by driving end, handle, rolling pawl, rolling pawl support and baffle plate composition, driving end and handle one-body molded, described driving end is the cylindrical body of hollow, cylindrical inner surface is evenly provided with plum blossom notch vertically, cylindrical two bottom surfaces have through hole, rolling pawl support is by circular bottom plate and be set in qually spaced in circular bottom plate small column circumferentially and form, rolling pawl support is close to cylindrical inner surface and is arranged, rolling pawl is arranged between plum blossom notch and rolling pawl support, baffle plate is provided with tapped hole, baffle plate and driving end are connected by screw.
Anti-theft nut outer surface is cylindrical, and outer surface is smooth, and the surface of contact of common wrench and anti-theft nut does not rub, and therefore, common wrench cannot turn anti-theft nut.And anti-theft nut spanner of the present invention is enclosed within after on the columniform outer surface of anti-theft nut by the cylindrical body of hollow, as shown in Figure 4, because rolling pawl is arranged in plum blossom notch, when turn clockwise spanner time, rolling pawl is rotated counterclockwise in plum blossom notch relative to spanner, rolling pawl reduces apart from the distance of nut, again because the internal surface of nut and spanner can not be out of shape, therefore, rolling pawl meeting compression nut, several rolling pawl acts on simultaneously and nut only must be compressed, and as shown in Figure 9, thus drives nut rotation.In like manner, when nut backed out by needs, only spanner need be rotated counterclockwise.
As improvement of the present invention, described rolling pawl conically.
Face width on conical rolling pawl, below narrow, be more conducive to rolling pawl clamping anti-theft nut cylindrical outer surface, drive nut rotation.
As a further improvement on the present invention, described through hole and tapped hole are 4.
4 through holes and 4 tapped holes can ensure that baffle plate and driving end are fastenedly connected.
Further improve as of the present invention, described rolling pawl and described plum blossom notch are 8.
3 rolling pawls can clamp the cylindrical outer surface of anti-theft nut in theory, and rolling pawl is more, and the effect of clamping is better, but rolling pawl must cause cost to increase too much.
Further improve as of the present invention, described baffle plate is circular.
Circular baffle plate coordinates the cylinder top end of driving end more attractive in appearance, practical.
The part that the present invention does not explain all adopts prior art.
In sum, the invention has the beneficial effects as follows, anti-theft nut can only be turned by Special anti-theft nut spanner, and can not be turned by Allen wrench, and equipment is not easy stolen.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.As shown in the FIG., a kind of anti-theft nut and spanner, be made up of nut 1 and spanner 2, described nut 1 outside is cylindrical, inside is common v thread, described spanner 2 is by driving end 3, handle 4, rolling pawl 5, rolling pawl support 6 and baffle plate 7 form, driving end 3 and handle 4 one-body molded, described driving end 3 is the cylindrical body of hollow, cylindrical inner surface is evenly provided with plum blossom notch 9 vertically, cylindrical two bottom surfaces have through hole, rolling pawl support 6 is by circular bottom plate and be set in qually spaced in circular bottom plate small column circumferentially and form, rolling pawl support 6 is close to cylindrical inner surface and is arranged, rolling pawl 5 is arranged between plum blossom notch 9 and rolling pawl support 6, baffle plate 7 is provided with tapped hole 8.Described through hole and tapped hole 8 are 4.Described rolling pawl 5 and described plum blossom notch 9 are 8.Described baffle plate 7 is circular.Rolling pawl 5 is cylindrical or conical.
First rolling pawl support 6 is arranged in the cylindrical body of driving end 3, again rolling pawl 5 is arranged in the interval between plum blossom notch 9 and small column, interval between adjacent two small columns is slightly less than the maximum diameter of rolling pawl 5, make rolling pawl 5 can stretch into interval between adjacent two small columns a little, finally cover baffle plate 7, and with screw, baffle plate 7 and driving end 3 are fixed.
During use, first driving end is enclosed within the outer surface of barrel nut, turn clockwise spanner again, rolling pawl supporting frame is driven to rotate together while spanner rotates, rolling pawl is rotated counterclockwise in plum blossom notch relative to spanner, rolling pawl reduces (as shown in figures 4 and 9) apart from the distance of nut, again because the internal surface of nut and spanner can not be out of shape, therefore, rolling pawl is inevitable to be moved from the interval between adjacent two small columns to nut direction, now, rolling pawl meeting compression nut, several rolling pawl acts on simultaneously and nut only must be compressed, thus drive nut rotation.
