The utility model is characterized in that the theftproof threaded sleeve is composed of a front theftproof threaded sleeve, a rear theftproof threaded sleeve and an expansion locking piece; a guiding hole, a transition hole and a conical hole are arranged in the front theftproof threaded sleeve, a clamping groove is arranged between the guiding hole and the transition hole, and a theftproof hole is arranged in the rear theftproof threaded sleeve. The utility model has the advantages of convenient operation, simple structure and favorable theftproof performance; besides, the utility model can not be demounted by common tools, and the utility model is suitable for various mechanical bolts of 6 M / M; the utility model can bed used for installing any fastening piece requiring the theftproof function.
Description
A kind of Theft-proof nut, it belongs to the reinforcing fitting on a kind of screw, particularly a kind of Theft-proof nut that guarantees that screw is not arbitrarily dismantled.
In common occasion, use screw to connect certain object, generally be to tear open, unload conveniently in order to guarantee, be beneficial to maintenance, transform etc.But also some special occasion can not be removed after requiring to connect object with screw easily, and requires to install and will make things convenient for.For example: the licence plate of various vehicles.Because use normal screws to install now, though easy for installation, also be disassembled easily simultaneously, stolen easily.
The purpose of this utility model is to provide a kind of swivel nut of reinforcing and sealing the normal screws nail, makes screw install and but can not be dismantled easily easily.
The purpose of this utility model is achieved in that
A kind of Theft-proof nut, it is characterized in that it is made up of preceding Theft-proof nut 1, back Theft-proof nut 8 and expansion locking plate 7, in preceding Theft-proof nut 1, be provided with pilot hole 2, transitional pore 4 and cone shape hole 5, between pilot hole 2 and transition 4, be provided with draw-in groove 3, the diameter of draw-in groove 3 connects a screw hole 6 greater than the diameter of transitional pore 4 and pilot hole 2 at cone shape hole 5 places; In the Theft-proof nut 8 of back, be provided with antitheft hole 9; Expansion locking plate 7 is the sphere circular metal plate, and the diameter of draw-in groove 3 is than the big 4～6mm of diameter of transitional pore 4 and pilot hole 2.
Accompanying drawing 1 is the structural representation of preceding Theft-proof nut of the present utility model;
Accompanying drawing 2 is the structural representation of Theft-proof nut of the present utility model;
Accompanying drawing 3 is the structural representation of expansion locking plate of the present utility model;
Accompanying drawing 4 is the assembly structure schematic representation of user mode of the present utility model;
Be embodiment of the present utility model with accompanying drawing 1,2,3,4 below, the utility model further specified:
The diameter of the screw hole 6 in the utility model should match with the diameter of employed screw; The diameter in the antitheft hole 9 in the back Theft-proof nut 8 should be slightly larger than the external diameter of employed nut 13, but diameter difference between the two must not so both be convenient to installation greater than 2～3mm, can not dismantled easily after can guaranteeing again to install.
At first preceding Theft-proof nut 1, licence plate 10, licence-plate support or bumper 11 are linked up during use, from antitheft hole 9, nut 13 is placed on the screw 12, with a flat mouthful bottle opener screw 12 is tightened in the Theft-proof nut 1 in the past with screw 12.The edge that expansion locking plate 7 is placed on pilot hole 2 knocks the sphere of expansion locking plate 7 with hammer and punching pin, makes expansion locking plate 7 enter draw-in groove 3 and makes sphere become flat, snaps in the draw-in groove 3.
The utility model is simple in structure, and is easy for installation, do not bore the expansion locking plate or uses special-purpose cutting method just can't dismantle once installing, and played good antitheft effect.The utility model profile is small and exquisite, and cost is lower, and can use with various screw fit, can be used for installing the antitheft fastening piece of any needs, as antitheft door, burglarproof lock, license plate, various labels etc.
