Abstract
The utility model discloses a guard bar theftproof nut which comprises a nut body. A radial threaded hole is formed in the middle of the nut body, one end of the nut body is of an annular hemline structure, and the nut is of an arc-shaped hexagonal structure. The arc-shaped hexagonal structure is composed of a first arc face, a second arc face, a third arc face, a fourth arc face, a fifth arc face and a sixth arc face, the length of the first arc face, the length of the third arc face and the length of the fifth arc face are equal, the length of the second arc face, the length of the fourth arc face and the length of the sixth arc face are equal, the length of the first arc face, the length of the third arc face and the length of the fifth arc face are larger than the length of the second arc face, the length of the fourth arc face and the length of the sixth arc face, the first arc face and the second arc face are connected in an end-to-end mode, the second arc face and the third arc face are connected in an end-to-end mode, the third arc face and the fourth arc face are connected in an end-to-end mode, the fourth arc face and the fifth arc face are connected in an end-to-end mode, the fifth arc face and the sixth arc face are connected in an end-to-end mode, and the sixth arc face and the first arc face are connected in an end-to-end mode. The nut is hard to unscrew by a general tool after being screwed down, and the theft prevention effect is achieved.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of guardrail anti-theft nut.
Background technique
Existing nut is generally equilateral hexagonal structure, the nut of this structure generally can screw easily with various Wrenchs, but this equipment that has also caused some to connect in this way is easily stolen, the particularly outdoor guardrail that need to connect with nut, be easy to just can to back out nut with instruments such as spanners to person steathily guardrail is stolen, thereby caused loss.
Summary of the invention
The purpose of this utility model is to design a kind of guardrail anti-theft nut.
To be solved in the utility model is that the nut of existing guardrail easily unloads with general spanner and the problem of being stolen.
The technical solution of the utility model is: comprise nut body, in the middle of described nut body, be provided with radial screw bore, described nut body one end is ring-type skirt structure, described nut is arc hexagonal structure, and described arc hexagonal structure is made up of the first cambered surface, the second cambered surface, the 3rd cambered surface, the 4th cambered surface, the 5th cambered surface and the 6th cambered surface.
Described first, the 3rd, the 5th cambered surface is equal in length, the second, the 4th, the 6th cambered surface is equal in length, the first, the 3rd, the 5th cambered surface length be greater than second, the 4th, the 6th cambered surface, institute's first cambered surface of telling and the second cambered surface join end to end and connect, institute's second cambered surface of telling and the 3rd cambered surface join end to end and connect, institute's the 3rd cambered surface of telling and the 4th cambered surface join end to end and connect, institute's the 4th cambered surface of telling and the 5th cambered surface join end to end and connect, institute's the 5th cambered surface of telling and the 6th cambered surface join end to end and connect, and institute's the 6th cambered surface of telling and the first cambered surface join end to end and connect.
Adopt design proposal of the present utility model, by designing this nut hexagonal arc-shaped structure, general Wrench is difficult to and nut forms coupling, and six face limits are all arcuate structure, can reduce the area of contact of nut and other instruments, make stressed minimizing between instrument and nut, use hammer to beat and be also difficult to obtain force bearing point, nut is difficult to turn on general instrument after tightening again, and has reached antitheft effect.
The utlity model has the antitheft advantage of energy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the utility model comprises nut body, in the middle of described nut body, be provided with radial screw bore 2, described nut body one end is ring-type skirt structure 1, and described nut is arc hexagonal structure 3.
As shown in Figure 2: described arc hexagonal structure 3 is by the first cambered surface 4, the second cambered surface 5, the 3rd cambered surface 6, the 4th cambered surface 7, the 5th cambered surface 8 and the 6th cambered surface 9 form, the first cambered surface 4, the 3rd cambered surface 6, the 5th cambered surface 8 is equal in length, the second cambered surface 5, the 4th cambered surface 7, the 6th cambered surface 9 is equal in length, the first described cambered surface 4, the 3rd cambered surface 6, the 5th cambered surface 8 length are greater than the second cambered surface 5, the 4th cambered surface 7, the 6th cambered surface 9, institute's first cambered surface 4 of telling and the second cambered surface 5 join end to end and connect, institute's second cambered surface 5 of telling and the 3rd cambered surface 6 join end to end and connect, institute's the 3rd cambered surface 6 of telling and the 4th cambered surface 7 join end to end and connect, institute's the 4th cambered surface 7 of telling and the 5th cambered surface 8 join end to end and connect, institute's the 5th cambered surface 8 of telling and the 6th cambered surface 9 join end to end and connect, institute's the 6th cambered surface 9 of telling and the first cambered surface 4 join end to end and connect.By designing this nut hexagonal arc-shaped structure, general Wrench is difficult to and nut forms coupling, and six face limits are all arcuate structure, can reduce the area of contact of nut and other instruments, make stressed minimizing between instrument and nut, use hammer to beat and be also difficult to obtain force bearing point, nut is difficult to turn on general instrument after tightening again, and has reached antitheft effect.
