Abstract
The utility model relates to an anti-theft nut for the automobile plate with a concave surface and a convex surface; an internal nut is arranged for fastening and the shape is like a hollow round head bolt which is embedded in the round groove of an external nut; an internal hole is equipped with threads which are matched with a screw rod and the outside is equipped with fine left-hand shallow threads which are matched with the external nut. The external nut shape is the same as a hexagon, a central hole is fine left-hand threads, which are matched with the internal nut; the locking strength is lower than that of the internal nut and the screw rod. The combined nut is arranged in the screw rod and screwed down; when the rated torque is reached, the external nut threads destroy sliding wires and can only skid around the internal nut to realize the anti-theft function. The end cap of the internal nut is designed to be an end with a concave surface and a convex surface, the utility model can be made of stainless steel or colorful plastic which is elegant 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 male and fomale(M﹠F) license plate 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) license plate 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 the same hexagon nut of external form, mesopore are 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 spanner 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 the same hexagon nut of external form, mesopore are 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 spanner 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) license plate 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 the left-handed shallow thread of closely-pitched (3) that mates with outer nut, the same hexagon nut of outer nut external form, 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) license plate anti-theft nut of claim 1, it is characterized in that: the circular cap cover of inner nut, the circular groove (4) of embedding outer nut.
3. by the described male and fomale(M﹠F) license plate anti-theft nut of claim 1, it is characterized in that: the bolt head cap lid of its inner nut, be arranged to the male and fomale(M﹠F) end socket.
