Abstract
The utility model relates to a concave and convex tubular anti-theft nut of a license plate, and is characterized in that an inner nut having the fastening function and a hollow round head bolt are provided; the bolt is embedded in a round 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 the exterior nut is damaged, and skid only occurs to the periphery of the inner nut to prevent theft; the cap of the inner nut is designed to be a concave and 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 male and fomale(M﹠F) vehicle license tube type 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 male and fomale(M﹠F) vehicle license tube type 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 hollow snap bolt, its cap embeds the circular 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.Earlier with inner nut, the outer nut of packing into screws into a suit assembled nut during use.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, be arranged to the male and fomale(M﹠F) end socket with the bolt head cap lid of inner nut, available stainless steel or colored plastic, 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 sphere 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 cylindrical cap of concavo-convex planar end socket of 1. inner nuts among the figure is 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 round end cap interior circular 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 the hollow snap bolt, and its cap embeds the circular groove (4) of outer nut, and 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 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 (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 bolt head cap lid of inner nut, be arranged to the male and fomale(M﹠F) 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. male and fomale(M﹠F) vehicle license tube type 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 hollow snap bolt, 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 male and fomale(M﹠F) vehicle license tube type anti-theft nut of claim 1, it is characterized in that: the cap of inner nut, the circular groove (4) of embedding outer nut.
3. by the described male and fomale(M﹠F) vehicle license tube type anti-theft nut of claim 1, it is characterized in that: the cap of its inner nut, be arranged to the male and fomale(M﹠F) end socket.
