Abstract
The utility model relates to a spheric bossed decorative tubular anti-theft nut, and is characterized in that an inner nut having the fastening function and a hollow flat head conic cap bolt are provided; the cap is embedded in a conical groove of an exterior nut; an inner hole is provided with female thread matched with a screw; the exterior is provided with closely-pitched levortatory shallow thread matched with the exterior nut. The exterior nut is tubular; a central hole is provided with closely-pitched levortatory female thread matched with the inner nut; the locking strength of the central hole and the inner nut is lower than the locking strength of the inner nut and the screw. After the assembled nut is arranged in the screw, and is screwed down to the torque rating, the thread of nuts having short service lives is damaged, and skid only occurs to the periphery of the inner nut; the cap of the inner nut is designed to be a spheric convex end plate made of stainless steel or colorful plastic; the utility model is both handsome and bright, and conventional tools can not be used to clamp or take down the nut, and the utility model plays a bright and colorful decorative role that conventional anti-theft nuts can not have.
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 ball bossage tube-like anti-theft 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 ball bossage tube-like anti-theft 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 that the tack top at the conical cap of tack is provided with a ball convex surface 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 ball convex 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 flattened conical shape cap of 1. inner nuts adds ball convex-shaped 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 top of the conical cap of tack of inner nut, a ball convex surface end socket is set, 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. ball bossage tube-like anti-theft 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 ball bossage tube-like anti-theft nut of claim 1, it is characterized in that: the conical cap tack of the tack of its inner nut top is provided with a ball convex surface end socket.
3. by the described ball bossage tube-like anti-theft nut of claim 1, it is characterized in that: the conical cap of the ball convex surface end socket of inner nut, the cone-shaped groove (4) of embedding outer nut.
