Abstract
The utility model relates to a flatheaded tubular anti-theft anti-destroy nut; the utility model is characterized in that an internal nut is arranged for fastening and the shape of the internal nut is like a hollow flatheaded bolt with a tapered cap which is embedded into the tapered groove of an external nut; an internal hole is equipped with female threads which are matched with a screw and the outside is equipped with fine left-hand shallow threads which are matched with the external nut. The external nut is a tubular one and a central hole is equipped with fine left-hand female threads which are matched with the internal nut; the locking strength is lower than that of the internal nut and the screw. The combined nut is arranged in the screw and screwed down; when the rated torque is reached, the threads of a disposable nut destroy sliding wires and can only skid around the internal nut; the cap of the internal nut is designed to be a plane end and the utility model can be made of stainless steel or colorful plastic; the utility model is elegant in appearance and colorful and can not be dismantled with conventional tools; in this way, the utility model can play an ornamental role with color compared with the ordinary anti-theft nut.
Description
Technical field
The utility model relates to a kind of nut part, especially license plate of fastening piece and decorates anti-theft nut.
Background technique
At present, known conventional nut is convenient to loading and unloading because of it, also is convenient to the theft of crime one's share of expenses for a joint undertaking and destroys; Some have the nut of anti-theft feature, but lack decorative artistic effect.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of flat-top tube-like anti-theft anti-damaged nut, just can reach purpose not only antitheft but also attractive in appearance.
The technical scheme in the invention for solving the technical problem is: the flat-top tube-like anti-theft anti-damaged nut that is combined by inner nut and outer nut, it is characterized in that: the inner nut of fastening effect together is set, external form is as the conical cap screw of hollow tack, its cap embeds the cone-shaped groove of outer nut, endoporus is and the box thread of screw rod coupling that the outside is the left-handed shallow thread of closely-pitched that mates with outer nut.Outer nut is only to work the short-lived nut that drives the fastening effect of inner nut, and external form is a tubulose, and mesopore is and the left-handed box thread of closely-pitched of inner nut coupling that its locking intensity is lower than the locking intensity of inner nut and screw rod.The outer nut of earlier inner nut being packed into during use screws into a suit assembled nut.This assembled nut is packed into and is tightened by pipe wrench behind the screw rod, and when reaching rated torque, short-lived outer nut thread damage stripped thread can only skid in the inner nut periphery, just again interior tightening nut can't be unloaded with conventional means and instrument, to reach antitheft purpose.The more important thing is, the through hole of inner nut is arranged to blind hole, the tack of the conical cap of tack is arranged to the plane end socket, makes it increase very strong decorative effect.Useful stainless steel or colored plastic are made, and light not only attractive in appearance is gorgeous but also can't dismantle with conventional tool holder, and that plays that general anti-theft nut can't play has a coloured decorating action of light.Here be noted that spiro rod length, behind the locking object, can not surmount in the concave surface end socket empty.
The beneficial effects of the utility model are: simple in structure, tamper robber is functional, ornamental by force, cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is an inner nut panorama schematic representation, and Fig. 2 is an outer nut panorama schematic representation, and Fig. 3 is that inner nut is dissected schematic representation, and Fig. 4 is that outer nut is dissected schematic representation, and Fig. 5 is that the assembled nut that is assembled into is dissected schematic representation, and Fig. 6 is a schematic top plan view.
The conical cap of 1. inner nuts is arranged to plane end socket among the figure, 2. with the coarse thread box thread of screw rod coupling, 3. with the left-handed shallow thread of closely-pitched of outer nut coupling, 4. with inner nut cap inner conical groove movingly, 5. with the left-handed box thread of closely-pitched of inner nut coupling.
Embodiment
In the drawings, the inner nut of fastening effect (1) together is set, external form is as hollow tack conical screw, its cap embeds the cone-shaped groove (4) of outer nut, endoporus is and the box thread (2) of screw rod coupling that the outside is the left-handed shallow thread of closely-pitched (3) that mates with outer nut. outer nut is only to work a short-lived nut that drives the fastening effect of inner nut, and external form is a tubulose, mesopore is and the left-handed box thread of closely-pitched (5) of inner nut coupling that its locking intensity is lower than the locking intensity of inner nut and screw rod.This assembled nut is packed into and is tightened by pipe wrench behind the screw rod, and when reaching rated torque, short-lived nut thread destroys stripped thread, can only skid in the inner nut periphery, just again interior tightening nut can't be unloaded with conventional means and instrument, to reach antitheft purpose.In addition with the tack of the conical cap of tack, be arranged to the plane end socket, light not only attractive in appearance is gorgeous but also can't dismantle with conventional tool holder, and that plays that general anti-theft nut can't play has a coloured decorating action of light.
Claims (3)
1. flat-top tube-like anti-theft anti-damaged nut, combine by inner nut and outer nut, it is characterized in that: the inner nut of fastening effect (1) together is set, external form is as the conical screw of hollow tack, endoporus is and the box thread (2) of screw rod coupling that the outside is and the left-handed shallow thread of closely-pitched (3) of outer nut coupling that the outer nut external form is a tubulose, mesopore is and the left-handed box thread of closely-pitched (5) of inner nut coupling that its locking intensity is lower than the locking intensity of inner nut and screw rod.
2. by the described flat-top tube-like anti-theft anti-damaged nut of claim 1, it is characterized in that: the conical cap tack of its inner nut, be arranged to the plane end socket.
3. by the described flat-top tube-like anti-theft anti-damaged nut of claim 1, it is characterized in that: the conical cap (1) of the tack of inner nut, the cone-shaped groove (4) of embedding outer nut.
