Description
Technical field
The utility model relates to a kind of device that is used for fastening goods vehicle spare tyre, and any installing/dismounting of particularly a kind of energy also has the burglarproof lock silk of lock function.
Background technique
Present known goods vehicle spare tyre all is fastening with the regular screw threads bar, the threaded stem that is used for fastening spare tyre does not have the function of lock, so can not be antitheft, do not notice that slightly just allowing the lawless person take advantage of a weak point steals spare tyre, cause economically loss and inconvenience for the shipping driver.
Summary of the invention
So the purpose of this utility model is not have the defective that the function of lock can not be antitheft at threaded stem, the special invention any installing/dismounting of a kind of energy and have the burglarproof lock silk of lock function.
The purpose of this utility model realizes as follows: described burglarproof lock silk comprises nut, screw rod, overcoat and screwdriver, have the groove that a plurality of not aliquot-sized are identical or different, shape is identical or different on the cylindrical of nut and screw head, two overcoats are set on the screw rod, under tightening state, nut and screw head all fall within the overcoat, overcoat then is stuck in the root of nut and screw head, one gap is arranged, so any mounting and dismounting tool does not all reach nut and screw head between the outer wall of the inwall of overcoat and nut and screw head; The endoporus of screwdriver is provided with the convex tendon that is complementary with groove, and the cylindrical of screwdriver is not more than the cylindrical in the gap between overcoat and nut 1 and the screw head, screwdriver can be inserted in the gap be enclosed within on nut and the screw head again.
The outside of described nut and screw head is circular, and the inwall of overcoat also is circular.
Good effect of the present utility model is as follows: because overcoat encases nut and screw head fully under tightening state, make any mounting and dismounting tool all not reach nut and screw head, even touched also because be circular and skid, so the stranger just can't turn on nut, realized anti-theft feature to the goods vehicle spare tyre.And the user because special-purpose screwdriver is arranged, just can take off or load onto tire by the smooth opening nut; Because this burglarproof lock of every suit silk is joined the special-purpose screwdriver of a cover, and is not general mutually between every cover, so other also has the people of same burglarproof lock silk, also can't open others' burglarproof lock silk.
