The utility model discloses a loss-resisting nut, which comprises a screw nut antitheft sleeve and a toe hook. A threaded rod between the bow of a bolt (2) and a screw nut (5) is sheathed with a main washer (1) and an auxiliary gasket (3). The outside of the screw nut (5) is sheathed with the screw nut antitheft sleeve. The convex toe hook (4) at the end of the screw nut antitheft sleeve (6) is inner hooked at the inner end surface of the screw nut (5) to make the screw nut antitheft sleeve sheath fixedly at the outside of the screw nut. The convex toe hook can prevent that the grip wrench or spanner or the like is used to steal the screw nut as well as that the general tool is used to steal the screw nut. The utility model has the advantages of simple structure, low cost and easy popularization and application, and is suitable to the matching of the bolt and screw nut.
Description
Technical field: the utility model relates to anti-theft device, particularly a kind of nut anti-theft device.
Background technique: after bolt and nut of the prior art cooperates; because nut does not have theft-preventing protecting device; very easily used general utility tool by the people; unload easily, take away; thereby bring potential safety hazard for relevant device, facility; even cause personal property loss, particularly outdoor facility, as the protective baffle plate on the high-grade highway, nut on the electric power pylon is stolen and economic loss that cause is particularly outstanding.
Summary of the invention: the purpose of this utility model is to provide a kind of nut anti-theft device, utilizes this nut anti-theft device can prevent that nut is stolen, reaches the purpose of protection equipment, facility.
Formation of the present utility model: collude by nut stealingproof sleeve and toe and to form, suit main washer 1 and auxilliary packing ring 3 on the threaded stem between bolt 2 heads and the nut 5, at nut 5 outsides cover loading nut stealingproof sleeve 6, the toe of nut stealingproof sleeve 6 ends colludes 4 and colludes on the interior edge face of nut 5.
Nut stealingproof sleeve 6 is cylindrical shapes, and uniform convex toe colludes 4 on an end of cylinder.
Compared with the prior art; the utility model is after bolt, nut are fastening; disposed a burglarproof sleeve in the nut outside; burglarproof sleeve and protected nut have certain clearance, and be free to rotate, and a plurality of toes of its end collude overhead kick on nut end face; make burglarproof sleeve firmly be enclosed within the nut outside; it both can prevent that the instrument of pipe tongs, wrench and so on from stealing nut, also can prevent before the nut stealingproof sleeve sheds, and used general tool to steal nut.
Nut stealingproof sleeve of the present utility model has only and uses special tool and can unload below the knocking of hammer, hammer knocks special tool must send sizable sound, this can startle the personnel of patrolling, so that in time find stealer, in time hit, this device does not have at night and is difficult to dismounting under the condition of illumination, is difficult for being stolen by stealer.
The utility model is simple in structure, and is with low cost, is easy to apply.
