Abstract
The utility model provides a spherical surface license plate theftproof nut. An internal nut with clamp function has an appearance similar to a hollow round head bolt which is embedded into a circular groove of an external nut; an inner hole has threads matching with a screw, and the outside has fine left hand shallow threads matching with the external nut; the external nut has an appearance the same as a hex nut, and the middle hole has fine left hand shallow threads matching with the internal nut; the locking intensity of the external nut is lower than that of the internal nut and the screw. The combined nut is packed into the screw and is screwed down, and when up to the rating torque, the threads of external nut damage the sliding filament and are only capable of skidding on the periphery of the internal nut to fulfill the theftproof purpose; the bolt head hood of the internal nut is made into a spherical surface end closure which can be made of stainless steel or colorful plastic; therefore, the utility model is beautiful and colorful and can not be clamped or disassembled by common tools, thereby having the function of bright and colorful decoration which common theftproof nuts do 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 spherical surface vehicle license 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 spherical surface vehicle license 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 sphere 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 sphere end socket cylindrical cap of 1. inner nuts lid 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 sphere 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. spherical surface vehicle license 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 spherical surface vehicle license anti-theft nut of claim 1, it is characterized in that: the bolt head cap lid of its inner nut, be arranged to the sphere end socket.
3. by the described spherical surface vehicle license anti-theft nut of claim 1, it is characterized in that: the sphere circular cap cover of inner nut, the circular groove (4) of embedding outer nut.
