Description
Technical field
The utility model belongs to nut and screwing wrench technical field thereof, particularly relates to novel anti-theft nut and screwing wrench thereof.
Background technique
On transmission tower, pole tag and overhead line structures etc. are generally all in field, wilderness, and nut and shaft tower material are often stolen by lawless person, and cause shaft tower tilt or collapse, severe patient causes transmission of electricity accident.In order to avoid transmission tower material is stolen, first solve the antitheft problem of nut anti-theft.The anti-theft nut of current use is in order to antitheft, and general employing profile is columniform nut, and spanner general like this cannot be backed out.But if adopt the instruments such as pipe wrench, nut can be backed out equally, anti-theft effect is poor.
Model utility content
First technical problem that the utility model solves just is to provide a kind of novel anti-theft nut of good anti-theft effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the female nut body of band, the side of described nut body is round table-like, at least two inclination breach with vertical block face are provided with in nut body upper-end surface, described vertical block face Impact direction is consistent with described nut direction, at described nut body inner side surface, vertical medium position is provided with horizontal slot, described nut body screws its rightabout horizontal slot depth as shallow of horizontal slot depth ratio of side, direction, is provided with retaining ball in described horizontal slot.
Its additional technical feature is:
Described retaining ball is two;
Above described horizontal slot, be provided with ball place entrance, the radially inner side opening of described horizontal slot is less than the diameter of described retaining ball;
Place on entrance at described ball and be provided with shell fragment.
Novel anti-theft nut provided by the utility model compared with prior art, have the following advantages: one, owing to comprising the female nut body of band, the side of described nut body is round table-like, at least two inclination breach with vertical block face are provided with in nut body upper-end surface, described vertical block face Impact direction is consistent with described nut direction, at described nut body inner side surface, vertical medium position is provided with horizontal slot, described nut body screws its rightabout horizontal slot depth as shallow of horizontal slot depth ratio of side, direction, retaining ball is provided with in described horizontal slot, general spanner, pipe wrench or other spanner cannot be exerted oneself, can by nut at nut body upper end employing Special rotary spanner, and the retaining ball arranged inside nut body, retaining ball during nut is positioned at the darker side of horizontal slot, when counterrotating nut, retaining ball moves to opposite side, be stuck between nut and screw rod, nut can not be screwed off, its two, because described retaining ball is two, when avoiding single retaining ball, to screw off in process retaining ball at nut and skid, can not occur along the problem of horizontal slot movement, further increase anti-theft effect, its three, due to be provided with above described horizontal slot ball place entrance, the radially inner side opening of described horizontal slot is less than the diameter of described retaining ball, avoids retaining ball and comes off, be convenient to putting into of retaining ball, its four, be provided with shell fragment owing to placing on entrance at described ball, avoid the retaining ball put into and drop.
Second technical problem that the utility model solves just is to provide a kind of Special rotary spanner of above-mentioned novel anti-theft nut.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Comprise sleeve pipe and handle, be provided with in described sleeve pipe front end and found block face and vertical end face corresponding to inclination breach and inclined protrusions with described nut.
Its additional technical feature is:
At described sleeve pipe, lower end is provided with outer sleeve, the inner side surface of this outer sleeve is mate with nut body outer side surface round table-like.
Novel anti-theft nut Special rotary spanner provided by the utility model compared with prior art, have the following advantages: one, owing to comprising sleeve pipe and handle, be provided with in described sleeve pipe front end and found block face and vertical end face corresponding to inclination breach and inclined protrusions with described nut, being easy to just can by above-mentioned novel anti-theft nut screwing clamping; Its two, owing to being provided with outer sleeve at described sleeve pipe near lower end, the inner side surface of this outer sleeve is mate with nut body outer side surface round table-like, and outer sleeve inner side surface is close to the outside of novel anti-theft nut, avoids cannula tip dislocation, uses convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model novel anti-theft nut;
Fig. 2 is the structural representation of another kind of novel anti-theft nut;
Fig. 3 is the structural representation of Special rotary spanner.
Embodiment
Below in conjunction with accompanying drawing, the structure of the utility model novel anti-theft nut and use principle are described in further details.
As shown in Figure 1, the utility model novel anti-theft nut, comprise the nut body 2 with internal thread 1, the side of nut body 2 is round table-like, at least two inclination breach 4 with vertical block face 3 are provided with in nut body 2 upper-end surface, the Impact direction of vertical block face 3 is consistent with nut direction, at the inner side surface of nut body 2, vertical medium position is provided with horizontal slot 5, nut body 2 screws its rightabout horizontal slot depth as shallow of horizontal slot 5 depth ratio of side, direction, is provided with retaining ball 6 in horizontal slot 5.
Like this, general spanner, pipe wrench or other spanner cannot be exerted oneself, can by nut at nut body 2 upper end employing Special rotary spanner, and the retaining ball 6 arranged inside nut body 2, retaining ball 6 during nut is positioned at the darker side of horizontal slot 5, when counterrotating nut, retaining ball 6 moves to opposite side, be stuck between nut body 2 and screw rod, nut can not be screwed off.
Retaining ball 6 is preferably two, when avoiding single retaining ball, screws off retaining ball 6 in process skid at nut, can not occur, further increase anti-theft effect along the problem of horizontal slot movement.
As shown in Figure 2, above horizontal slot 5, be provided with ball place entrance 7, the radially inner side opening 51 of horizontal slot 5 is less than the diameter of retaining ball 6, avoids retaining ball 6 and comes off, be convenient to putting into of retaining ball 6.
Place on entrance 7 at ball and be provided with shell fragment 8, avoid the retaining ball put into and drop.
As shown in Figure 3, above-mentioned novel anti-theft nut Special rotary spanner comprises sleeve pipe 9 and handle 10, is provided with founds block face 3 and vertical end face 11 corresponding to inclination breach 4 and inclined protrusions 12 with nut in sleeve pipe 9 front end.Like this, being easy to just can by above-mentioned novel anti-theft nut screwing clamping.
At sleeve pipe 9, lower end is provided with outer sleeve 13, the inner side surface of this outer sleeve 13 is mate with nut body outer side surface round table-like.Like this, when tightening nut body, outer sleeve 13 inner side surface is close to the outside of novel anti-theft nut, avoids cannula tip dislocation, uses convenient.
Protection domain of the present utility model is not only confined to above-described embodiment, as long as the structure of structure and the utility model novel anti-theft nut and Special rotary spanner thereof is same or similar, just drops on the scope of the utility model protection.
