Abstract
The present invention discloses a kind of taper anti-theft screw cap, 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, is not more than the internal diameter of tapped hole without pit internal diameter; Interior nut is the round platform being provided with inner bolt hole, and interior nut sidewall is evenly equipped with multiple notch; Described interior nut is arranged in exterior nut cap, and its little round bottom is positioned at without pit, and large round bottom is positioned at annular groove; Described packing ring is arranged in annular groove.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.Toll breakdown down the screw thread do not damaged on screw rod, only nut is disposable products, greatly saves the manufacture cost of product link, has saved production material.
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, in the installation, the installation of expressway annex, the fixing of railroad track etc. of the connection of electric power transmission tower material of iron tower, power transmission and distribution gold utensil, common locking, antitheft spiral shell cannot be applied.
Summary of the invention
Given this, the object of the invention is to provide a kind of anti-theft screw cap not damaging screw flight.
For solving above technical problem, technological scheme provided by the invention is, provides a kind of taper anti-theft screw cap, 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, is not more than the internal diameter of tapped hole without pit internal diameter; Interior nut is the round platform being provided with inner bolt hole, and interior nut sidewall is evenly equipped with multiple notch; Described interior nut is arranged in exterior nut cap, and its little round bottom is positioned at without pit, and large round bottom is positioned at annular groove; Described packing ring is arranged in annular groove.
Preferably, described tapped hole is provided with inclined-plane, this inclined-plane is adjacent with annular groove.
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 do not damaged on screw rod, only nut is disposable products, greatly saves the manufacture cost of product link, has saved production material.
3, interior nut is tapered cup nut, can prevent exterior nut cap from loosening.
4, the position of nut in exterior nut cap in packing ring Absorbable organic halogens, avoids excesssive gap to be formed loosening.

In figure, 1 exterior nut cap, 11 tapped holes, 12 without pit, 13 annular grooves, 14 inclined-planes, nut in 2,21 notches, 3 packing rings.
Embodiment
Be described below in conjunction with accompanying drawing and a specific embodiment.
See Fig. 1 to Fig. 5.Taper anti-theft screw cap described by the present embodiment, comprises exterior nut cap 1, interior nut 2 and packing ring 3.Exterior nut cap 1, interior nut 2 and packing ring 3 all available metal material are made, as common iron, copper or other alloy materials.In the present embodiment, the material of nut can with various material of the prior art.The present invention is main is to provide a kind of new structure, and in this structure, it is inner that interior nut 2 and packing ring 3 are positioned at exterior nut cap 1.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 diameter.
Interior nut 2 is frustoconic shape, and its center is provided with inner bolt hole, and the screw thread on this inner bolt hole is identical with the screw thread of tapped hole 11.Interior nut 2 sidewall is evenly equipped with multiple notch 21, and notch 21 is longitudinally arranged, and its opening is positioned at the little round bottom side of round platform.Such set-up mode, makes the structure of interior nut 2 be divided into two functional parts, one be annular arrange multiplely press shell fragment, two is connect the ring pressing shell fragment, and in fact, above-mentioned to press shell fragment with above-mentioned ring be integrally.
Concrete mounting type is, interior nut 2 is arranged in exterior nut cap 1, and its little round bottom is positioned at without pit 12, 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 the large round bottom side of nut 2.
As preferred embodiment, tapped hole 11 and the critical part of annular groove 13 are provided with inclined-plane 14, and this inclined-plane is adjacent with annular groove 13.
Time fastening, exterior nut cap is relative with screw rod to be rotated, the temporary transient transfixion of interior nut, and after rotating certain stroke, packing ring is close to bottom the great circle of interior nut 2, and under the effect of frictional force, interior cap rotation advances.When 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, specifically, be pressed on above-mentionedly to press on shell fragment, under pressure, pressing shell fragment is pressed on screw rod, makes the screw thread on interior nut and the screw thread on screw rod fit 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.
