Abstract
The utility model relates to a screw portion of a fastening component. The existing anti-theft screw has no decorative effect, wherein the anti-theft screw for a drum-shaped spherical license plate comprises an inner screw and an outer female screw, which is characterized in that a round head spherical screw bolt which is formed through combining an inner screw which has fastening function and a screw rod whose external form is that the upper and lower nodes are concentric and the diameters are different is arranged, a cap cover is embedded in a circular groove of the outer female screw, coarse screw rod thread of the upper node is fine left-hand light thread which is matched with the outer female screw, the outer female screw is ephemeral female screw which only drives inner screw to carry out fastening function, the external shape of the outer female screw is spherical drum shape, a middle hole is fine left-hand female thread which is matched with the upper node screw rod of the inner screw, and locking strength of the fine left-hand female thread is lower than locking strength of the inner screw and female screw which is matched to lock. The assembled screw is packed in the locking female screw and is fastened by a pipe twist, when rated torque is achieved, screw thread of ephemeral female screw brocks sliding wire, which can only slide on the periphery of the inner screw, inner fastening screw can never be detached, and the anti theft and strongly decorative effect are acted.
Description
Technical field
The utility model relates to a kind of screw part of fastening piece.
Background technique
At present, known conventional screw 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 screw of anti-theft feature, are 0420098372.4,02153416.0 anti-theft screw as the patent No., but lack decorative artistic effect.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of drum type spherical surface vehicle license anti-theft screw, 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 drum type spherical surface vehicle license anti-theft screw that is combined by inner bolt and outer nut, it is characterized in that: the inner bolt of fastening effect together is set, external form is for two saving the snap bolt that the concentric different screw combinations of diameter forms up and down, its cap embeds the circular groove of outer nut, the thick screw flight of last joint, be the left-handed shallow nut line of closely-pitched with the outer nut coupling. outer nut is only to work the short-lived nut that drives the fastening effect of inner bolt, external form is the sphere drum type, mesopore be with inner bolt on the left-handed box thread of closely-pitched of joint screw rod coupling, its locking intensity is lower than the locking intensity of the nut of inner bolt and supporting locking. and elder generation is with inner bolt during use, the outer nut of packing into screws into a suit screw assemblies.This screw assemblies is packed into and is tightened by pipe wrench behind the locking nut, when reaching rated torque, short-lived nut thread destroys stripped thread, can only skid in the inner bolt periphery, just again interior fastening screw trip bolt can't be unloaded with conventional means and instrument, to reach antitheft purpose. the bolt head cap with inner bolt covers in addition, be arranged to the sphere end socket, available stainless steel or colored plastic, light not only attractive in appearance is gorgeous but also can't be with the dismounting of conventional tool holder, and that plays that general anti-theft screw can't play has a coloured decorating action of light.
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 bolt panorama schematic representation, and Fig. 2 is an outer nut panorama schematic representation, and Fig. 3 is that the inner bolt master looks schematic representation, and Fig. 4 is that outer nut is dissected schematic representation, and Fig. 5 is that the screw assemblies that is assembled into is dissected schematic representation, and Fig. 6 is a schematic top plan view.
The spherical shape end socket circular cap cover of 1. inner nuts among the figure, 2. with the left-handed shallow thread of closely-pitched of outer nut coupling, 3. with the coarse thread of locking nut coupling, 4. with the inner bolt circular cap cover movingly: circular groove, 5. with the left-handed box thread of closely-pitched of inner bolt coupling.
Embodiment
In the drawings, the inner bolt of fastening effect together is set, external form is for two saving the snap bolt that the concentric different screw combinations of diameter forms up and down, its cap embeds the circular groove (4) of outer nut, the thick screw flight of last joint, it is the left-handed shallow thread of closely-pitched (2) with the outer nut coupling, outer nut is only to work the short-lived nut that drives the fastening effect of inner bolt, external form is the sphere drum type, mesopore be with inner bolt on the left-handed box thread of closely-pitched of joint screw rod coupling, its locking intensity is lower than the locking intensity of the nut of inner bolt and supporting locking. and elder generation is with inner bolt during use, the outer nut of packing into, screw into a suit screw assemblies, this screw assemblies is packed into and is tightened by pipe wrench behind the locking nut, when reaching rated torque, short-lived nut thread destroys stripped thread, can only skid in the inner bolt periphery, just again interior fastening screw trip bolt can't be unloaded with conventional means and instrument, to reach antitheft purpose. the bolt head cap with inner bolt covers in addition, be arranged to the sphere end socket, available stainless steel or colored plastic, light not only attractive in appearance is gorgeous but also can't be with the dismounting of conventional tool holder, and that plays that general anti-theft screw can't play has a coloured decorating action of light.
Claims (3)
1. drum type spherical surface vehicle license anti-theft screw, combine by inner bolt and outer nut, it is characterized in that: the inner bolt of fastening effect together is set, external form is for two saving the snap bolt that the concentric different screw combinations of diameter forms up and down, the thick screw flight of last joint, it is the left-handed shallow thread of closely-pitched (2) with the outer nut coupling, outer nut is only to work the short-lived nut that drives the fastening effect of inner bolt, external form is the sphere drum type, the left-handed box thread of closely-pitched (5) that mates with inner bolt that mesopore is provided with that locking intensity is lower than inner bolt and supporting locking nut locking intensity.
2. by the described drum type spherical surface vehicle license anti-theft screw of claim 1, it is characterized in that: the circular cap cover of inner bolt, the circular groove of embedding outer nut.
