Abstract

The utility model relates to a raised shoulder and spherical concave surface tubular anti-theft screw for a vehicle license plate. The utility model is provided with an internal nut playing a fastening function, the appearance of the internal nut is like a hollow round head bolt, the internal nut is embedded into the circular groove of an external nut, a thread matched with a screw rod is arranged in the inner hole of the internal nut, and a fine thread left-hand shallow thread matched with the external nut is arranged outside the external nut. The appearance of the external nut is thick wall pipe-shaped, an arc bulge is arranged on the edge of the upper pipe mouth, a fine thread left-hand thread matched with the internal nut is arranged in the middle hole, and the locking intensity is lower than the locking intensity of the internal nut and the screw rod. After being installed into the screw rod, the combined nut is screwed down, when the rated torque is achieved, the thread of the external nut is destroyed and slipped, and can only slide on the periphery of the internal nut, and thereby the anti-theft purpose can be achieved. The bolt head cap of the internal nut is arranged into a spherical concave surface end socket, and can be made of stainless steel or colored plastics, thus being artistic and gorgeous and not being clamped and disassembled by using a conventional tool, thereby playing the glossy and colorful decoration function which can not be achieved by common anti-theft screws.

Description

Convex shoulder ball impression face vehicle license tube type anti-theft nut
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 convex shoulder ball impression face 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 convex shoulder ball impression face 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 the heavy wall tubulose, and the upper orifice edge is the arcuation projection, 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 ball impression face 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 the planar end socket of the ball impression of 1. inner nuts 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 round end cap interior circular groove movingly, 5. with the left-handed box thread of closely-pitched of inner nut coupling, the 6. upper orifice of arcuation projection.
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 the heavy wall tubulose, and the upper orifice edge is arcuation projection (6), 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 ball impression face 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)
