Description
Technical field
The utility model relates to a kind of nut and special spanner thereof
Background technique
Automobile tire is lost and is one and allows car owner's pain in the neck spare, has not only caused economic loss to the car owner, and has influenced the use of automobile.
And the nut that automobile tire uses is installed at present is standard piece, adopts outer hexagonal structure, therefore adopts present spanner just can to disassemble easily, provides convenience to the thief.
The model utility content
The purpose of this utility model just is to provide a kind of anti-theft nut, and this nut can not carry out dismounting with present common spanner, therefore can reach antitheft purpose.
The utility model also provides a kind of spanner that the dismounting anti-theft nut is used that is used for.
A kind of anti-theft nut is provided with endoporus on the nut body, endoporus one end is provided with internal thread, and the hole wall of the other end endoporus is provided with axial projection and/or groove, and the outer wall of nut body is the cylndrical surface.
The utility model also provides a kind of spanner that the dismounting anti-theft nut is used that is used for, it is characterized in that: there is boss described spanner end, the boss periphery be provided with axially be provided with along it with the anti-theft nut endoporus on projection and/or the groove groove and/or the projection of coincideing.
This anti-theft nut of the present utility model, because its outer wall is that the cylndrical surface does not have Point of Strength, when being used for the automobile tire installation, existing spanner does not have Point of Strength and can't use, and must just can load and unload with special tool, has therefore reached antitheft purpose.Adopt the utility model and the supporting spanner of anti-theft nut, then can realize the dismounting and the assembling of anti-theft nut easily.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
Embodiment 1
As depicted in figs. 1 and 2, be a kind of anti-theft nut, endoporus is set on the nut body, its endoporus one end is provided with internal thread 1 and is used for cooperating with bolt, the hole wall of the other end endoporus is provided with an axial projection 4 and 6 road grooves 2, and the outer wall 3 of nut body is the cylndrical surface.This structure can not use Allen wrench to mount and dismount owing to outer wall is that the cylndrical surface is feasible, thereby reaches antitheft purpose.
Projection 4 in the nut body endoporus and groove 2 are the Point of Strength of the instrument of dismounting and installation usefulness, therefore be understandable that according to its principle, except that mode as depicted in figs. 1 and 2 adopts the mode of projection and groove combination, also one or multi-channel projection can only be set, one or multi-channel groove perhaps is set.
Extremely shown in Figure 5 as Fig. 3, it is a kind of spanner that is used to load and unload nut shown in the embodiment 1, the one end is a boss, the boss periphery be provided with axially be provided with along it with the anti-theft nut endoporus on projection 4 and groove 2 groove 24 and the projection 22 of coincideing, make it can insert nut inner hole one end and can prevent that both from relatively rotating, so that nut is produced moment of torsion.
Spanner in the present embodiment is a socket wrench, and the other end is outer square head 20 to be connected with internal square hole assembling on the handle, and the square head sidewall has circular hole 23, can be used to shooting property ball, so that it is stuck in the cubic hole on the handle.One circle bulge loop 21 is arranged between square head and boss, be used for handle is positioned.Handle arrangement is identical with existing socket wrench, therefore no longer describes.
Though present embodiment is a socket wrench, is assembly parts,, handle forms a whole spanner on boss yet also can directly being set.
Claims (4)
