Abstract
The utility model discloses a kind of for antitheft bolt, comprise bolt shank and bolt head, the end face of bolt head offers deep gouge, and deep gouge comprises diapire and the sidewall perpendicular to diapire, and sidewall is surrounded by the curved wall connected successively and at least two rectangular side wall.Because the bolt head for antitheft bolt of the present utility model offers deep gouge, and deep gouge comprises diapire and the sidewall perpendicular to diapire, and sidewall is surrounded by the curved wall connected successively and at least two rectangular side wall.The profile of this deep gouge is not mated with the head configuration of common wrench, utilize common wrench cannot insert this deep gouge, therefore, stealer cannot utilize common wrench to be fastened on the disassembling bolts of the present utility model on wheel, thus plays anti-theft function to the part being similar to wheel.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to a kind of for antitheft bolt.
Background technique
The existing bolt for fastening automotive wheel is generally hexagon socket head cap screw, because hexagon socket head cap screw is very common, adopt common inner hexagon spanner just can carry out dismounting to it, therefore, the situation being very easy to cause automotive wheel stolen occurs, while causing car owner's economic loss, cause very large inconvenience also to the trip of car owner.
Model utility content
Just can by its dismounting by common wrench for bolt of the prior art, thus cause the technical problem that the part being similar to wheel is stolen, the utility model provides a kind of for antitheft bolt, this is used for antitheft bolt and common spanner can be prevented its dismounting, thus avoids being stolen by the part of this bolton.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
For an antitheft bolt, comprise bolt shank and bolt head, the end face of described bolt head offers deep gouge, and described deep gouge comprises diapire and the sidewall perpendicular to described diapire, and described sidewall is surrounded by the curved wall connected successively and at least two rectangular side wall.
Preferably, described curved wall is semicircular arc sidewall.
Preferably, the quantity of described rectangular side wall is two; Wherein, the width of two described rectangular side wall is identical, and arranges in 60 degree of angles.
Preferably, the quantity of described rectangular side wall is three; Wherein, the width of three described rectangular side wall is identical, and adjacent two described rectangular side wall are that 120 degree of angles are arranged.
Preferably, the quantity of described rectangular side wall is three; Wherein, the width of three described rectangular side wall is identical, and adjacent two described rectangular side wall are that 90 degree of angles are arranged.
Preferably, described bolt head is cylindrical.
Preferably, described curved wall and/or rectangular side wall offer keyway, the length direction of described keyway is identical with the thickness direction of described deep gouge.
Compared with prior art, the beneficial effect had for antitheft bolt of the present utility model is: because the bolt head for antitheft bolt of the present utility model offers deep gouge, and deep gouge comprises diapire and the sidewall perpendicular to described diapire, described sidewall is surrounded by the curved wall connected successively and at least two rectangular side wall.The profile of this deep gouge is not mated with the head configuration of common wrench, utilize common wrench cannot insert this deep gouge, therefore, stealer cannot utilize common wrench to be fastened on the disassembling bolts of the present utility model on wheel, thus plays anti-theft function to the part being similar to wheel.

In figure:
1-bolt head; 11-deep gouge; 12-keyway; 2-bolt shank.
Embodiment
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As Figure 1-4, embodiment of the present utility model discloses a kind of for antitheft bolt, comprise bolt shank 2 and bolt head 1, the end face of bolt head 1 offers deep gouge 11, deep gouge 11 comprises diapire and the sidewall perpendicular to diapire, and sidewall is surrounded by the curved wall connected successively and at least two rectangular side wall.
Because the bolt head 1 for antitheft bolt of the present utility model offers deep gouge 11, and deep gouge 11 comprises diapire and the sidewall perpendicular to diapire, and sidewall is surrounded by the curved wall connected successively and at least two rectangular side wall.The profile of this deep gouge 11 is not mated with the head configuration of common wrench, utilize common wrench cannot insert this deep gouge 11, therefore, stealer cannot utilize common wrench to be fastened on the disassembling bolts of the present utility model on wheel, thus plays anti-theft function to the part being similar to wheel.
The concrete structure of the deep gouge 11 offered for antitheft bolt of the present utility model has multiple: curved wall can be semicircular arc sidewall.
As shown in Figure 2, in a preferred embodiment of the present utility model, the quantity of rectangular side wall is two; The width of two rectangular side wall is identical, and arranges in 60 degree of angles.
As shown in Figure 3, in another preferred embodiment of the present utility model, the quantity of rectangular side wall is three; The width of three rectangular side wall is identical, and adjacent two rectangular side wall are that 120 degree of angles are arranged.
As shown in Figure 4, in another preferred embodiment of the present utility model, the quantity of rectangular side wall is three; The width of three rectangular side wall is identical, and adjacent two rectangular side wall are that 90 degree of angles are arranged.
The side face of the clamping device clamping screw head 1 of pliers and so on is utilized by of the present utility model for antitheft disassembling bolts for preventing stealer, in a preferred embodiment of the present utility model, bolt head 1 is processed into cylindrical, the side face of this bolt head 1 can be processed into smooth surface, particularly, side face can be machined to roughness is 1.6 μm.
For preventing of the present utility modelly being pulled off in fastener cycle for antitheft bolt, be processed into the bolt that performance rate is 12.9, the Nominal Tensile of the bolt of this grade is 1200MPa, yield ratio value is 0.9, its Rigidity and strength very large, therefore, it is possible to ensure can not to be pulled off or to fracture in disassembly process.
As in Figure 2-4, for increasing anti-theft feature further, the difficulty that the head improving spanner mates with deep gouge 11, curved wall and/or rectangular side wall offer keyway 12, and the length direction of keyway 12 is identical with the thickness direction of deep gouge 11.Will be appreciated that, be subject to the enlightenment of the deep gouge 11 of bolt head 1 of the present utility model, further keyway can be processed into special-shaped keyway, the forms such as such as taper keyway, trapezoidal keyway, with further in order to strengthen anti-theft feature.
Those skilled in the art's easy understand, in order to can dismounting of the present utility model for antitheft bolt, need the spanner that special outfit matches with the Internal periphery of deep gouge 11, the head of this spanner is inserted in deep gouge 11 and just can realize tightening or unclamping of bolt, use very convenient, and common wrench is difficult to carry out dismounting to this bolt.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
