Abstract
The invention discloses a conic antitheft nut which comprises an outer nut, an inner nut and a gasket. Inner holes of the outer nut comprise a threaded hole, a non-threaded hole and an annular groove in sequence, and the inner diameter of the non-threaded hole is no larger than that of the threaded hole. The inner nut is a circular truncated cone provided with an inner threaded hole and a plurality of groove openings are evenly formed in the side wall of the inner nut. The inner nut is installed in the outer nut, the small circular bottom of the inner nut is located in the non-threaded hole, and the large circular bottom of the inner nut is located in the annular groove. The gasket is installed in the annular groove. The conic antitheft nut has the looseness-resistant function and the antitheft function, integrates fastening, looseness resistance and the antitheft function, can be widely applied to the portions for connection, installation and the like and satisfies the requirement for production and life. If the conic antitheft nut is detached by force, threads on a screw are not damaged, the nut is a disposable product, the manufacturing cost of a connector product is greatly saved, and production materials are saved.
Description
Technical field
The present invention relates to a kind of nut.
Background technique
Existing locking, anti-theft screw cap, in unloading process, very easily damages screw flight, causes a whole set of bolt to become disposable products.Therefore,, at the aspect such as fixing of the installation of the installation of the connection of electric power transmission tower material of iron tower, power transmission and distribution gold utensil, expressway annex, railroad track, cannot apply common locking, antitheft spiral shell.
Summary of the invention
Given this, the object of the invention is to provide a kind of anti-theft screw cap that does not damage screw flight.
For solving above technical problem, technological scheme provided by the invention is, a kind of taper anti-theft screw cap is provided, and comprises exterior nut cap, interior nut and packing ring; The endoporus of described exterior nut cap is successively divided into tapped hole, without pit and annular groove, be not more than the internal diameter of tapped hole without pit internal diameter; Interior nut is the round platform that is provided with inner bolt hole, on interior nut sidewall, is evenly equipped with multiple notches; Described interior nut is arranged in exterior nut cap, at the bottom of its roundlet, is positioned at without pit, and large round bottom is positioned at annular groove; Described packing ring is arranged in annular groove.
Preferably, on described tapped hole, be provided with inclined-plane, this inclined-plane and annular groove are adjacent.
Preferably, the material of described packing ring is metal.
Compared with prior art, a technological scheme tool in technique scheme has the following advantages:
1, taper jam nut of the present invention, has locking, anti-theft feature, integrates fastening, locking, antitheft, can be widely used in the positions such as each connection, installation, meets the need of production, life.
2, toll breakdown down the screw thread not damaging on screw rod, only nut is disposable products, has greatly saved the manufacture cost of product link, has saved production material.
3, interior nut is tapered cup nut, can prevent that exterior nut cap is loosening.
4, packing ring can be stablized the position of interior nut in exterior nut cap, avoids excesssive gap to form loosening.

In figure, 1 exterior nut cap, 11 tapped holes, 12 without pit, 13 annular grooves, 14 inclined-planes, 2 interior nuts, 21 notches, 3 packing rings.
Embodiment
Describe below in conjunction with accompanying drawing and a specific embodiment.
Referring to Fig. 1 to Fig. 5.The described taper anti-theft screw cap of the present embodiment, comprises exterior nut cap 1, interior nut 2 and packing ring 3.Exterior nut cap 1, interior nut 2 and the equal available metal material of packing ring 3 are made, as common iron, copper or other alloy materials.In the present embodiment, the material of nut can be with various materials of the prior art.The present invention is main is to provide a kind of new structure, and in this structure, interior nut 2 and packing ring 3 are positioned at exterior nut cap 1 inside.The endoporus of exterior nut cap 1 is divided into three sections, is successively divided into tapped hole 11, without pit 12 and annular groove 13, is not more than the internal diameter of tapped hole 11 without pit 12 internal diameters.
Concrete mounting type is, interior nut 2 is arranged in exterior nut cap 1, is positioned at without pit 12 at the bottom of its roundlet, and large round bottom is positioned at annular groove 13; Described packing ring is arranged in annular groove 13, and namely, packing ring 3 is positioned at large round bottom one side of nut 2.
As preferred embodiment, be provided with inclined-plane 14 at tapped hole 11 with the critical place of annular groove 13, this inclined-plane is adjacent with annular groove 13.
When fastening, exterior nut cap is relative with screw rod to be rotated, and the temporary transient transfixion of interior nut is rotated after certain stroke, and packing ring is close to the great circle bottom of interior nut 2, and under the effect of frictional force, interior nut rotates and advances.Under the situation of returning exterior nut cap, exterior nut cap counterrotating, after turning an angle, inclined-plane 14 is pressed on the outer side wall of interior nut, definite says, is to be pressed on above-mentioned pressing on shell fragment, under pressure, press shell fragment and be pressed on screw rod, make the screw thread laminating on screw thread and the screw rod on interior nut tightr.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
