Abstract
The utility model relates to a bolt part of a fastener; the existing anti-theft bolts have no ornamental effect; then ornamental anti-theft bolt with a convex surface consists of an internal bolt and an external nut. The utility model is characterized in that an internal bolt is arranged for fastening, the shape of the internal bolt is a cone bolt with a spherical convex surface which consists of combined upper and lower sections of concentric screw rods, the diameters of which are different; the cap is embedded into the tapered groove of an external nut; the upper section is equipped with thick screw rod threads which are matched with fine left-hand shallow threads arranged on the external nut; the external nut is a disposable nut which can only drive an internal nut to be fastened and the shape is the same as a hexagon; a central hole is equipped with fine left-hand female threads which are matched with the upper section of screw rod of the internal bolt; the locking strength is lower than that of the internal bolt and a matched locking nut; the combined bolt is arranged in the locking nut and screwed down by a pipe wrench; when the rated torque is reached, the disposable nut threads destroy sliding wires and can only skid around the internal bolt; in this way, the internal fastening bolt can not be dismantled and the utility model can realize the anti-theft and strong ornamental effects.
Description
Technical field
The utility model relates to a kind of screw part, especially ball bossage anti-theft screw of fastening piece.
Background technique
At present, known conventional screw is convenient to loading and unloading because of it, also is convenient to crime one's share of expenses for a joint undertaking theft and destroys, and some have the screw of anti-theft feature, is 0420098372.4,02153416.0 anti-theft screw as the patent No., but lacks decorative artistic effect.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of ball bossage 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 ball convex surface license plate 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 conical cap bolt that the concentric different screw combinations of diameter forms up and down, its cap embeds the cone-shaped groove of outer nut, the thick screw flight of last joint, be the left-handed shallow thread 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, the same hexagon nut of external form, 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, 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 spanner 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, balling-up convex surface end socket is set, 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 conical cap of the ball convex-shaped end socket of 1. inner bolts 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 inner bolt round end cap female cone groove movingly, 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 conical cap bolt that the concentric different screw combinations of diameter forms up and down, its cap embeds the cone-shaped groove (4) of outer nut, the thick screw flight of last joint, be 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, the same hexagon nut of external form, mesopore be with inner bolt on the left-handed box thread of closely-pitched (5) 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 spanner 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. other is with the conical cap of inner bolt, balling-up convex surface end socket is set, 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. ball bossage 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 conical cap 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, the same hexagon nut of external form, mesopore be with inner bolt on the left-handed box thread of closely-pitched (5) of joint screw rod coupling, its locking intensity is lower than the locking intensity of the nut of inner bolt and supporting locking.
