Abstract
Aimed at the defects of the conventional theft-proof nut, i.e. complex structure, material waste in production and poor theft-proof effect in use, the utility model discloses a theft-proof nut with a tapered periphery. The theft-proof nut comprises a nut body with the polygonal periphery, and the nut body is provided with an internal thread, on which a curved groove is cut. The theft-proof nut is characterized in that: the periphery of the nut body is provided with a taper, and the groove in the nut body is a groove, one end of which is perpendicular and the other end of which is curved.
Description
Technical field
The utility model discloses a kind of anti-theft nut of outer marginal zone tapering, belong to the standard piece product technical field, especially relevant with anti-theft nut.
Background technique
Nut is a kind of of standard piece, and it cooperates with bolt, is used for fixing other object.Known nut comprises the nut body of polygonal outer rim, is shaped on screw thread in nut body.This existing bolt is in use laid down easily, can not be antitheft; In order to make nut safe in utilization, a kind of anti-theft nut has appearred on the market, and this anti-theft nut comprises the nut body of polygonal outer rim, is shaped on screw thread in nut body, is carved with the arcuation groove at the screw thread place, and spring, hoodle are installed in groove; Cap outside outside nut body, being set with.The defective of this existing anti-theft nut is a complex structure, wastes raw material in the production, and anti-theft effect is not good in the use.
Summary of the invention
Complex structure at existing anti-theft nut existence, waste raw material in the production, the not good defective of anti-theft effect in the use, the utility model discloses a kind of anti-theft nut of outer marginal zone tapering, the anti-theft nut of this outer marginal zone tapering is simple in structure, save material good anti-theft effect in the use during manufacturing.
Taked following technological scheme for realizing the purpose of this utility model:
Make a kind of anti-theft nut of outer marginal zone tapering, the anti-theft nut of this outer marginal zone tapering comprises the nut body of polygonal outer rim, in nut body, be shaped on screw thread, be carved with the arcuation groove at the screw thread place, it is characterized in that described nut body outer rim is shaped on tapering, the groove in the nut body is that an end is vertical, the other end is the groove of arcuation.
Nut body outer rim tapering described in the utility model, its axial dimension surpasses 50% of nut body axial dimension.
The utility model has the advantages that simple in structurely, save material good anti-theft effect during use during manufacturing.
Description of drawings
Further describe technical characteristics of the present utility model below in conjunction with accompanying drawing:
Fig. 1, an embodiment's of the utility model structural representation;
The side-looking structural representation of Fig. 2, embodiment Fig. 1;
The A--A sectional structure schematic representation of Fig. 3, embodiment Fig. 1.
Among the figure: 1, nut body 2, screw thread
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, among the figure 1 is the nut body of polygonal outer rim, in nut body 1, be shaped on screw thread, be carved with arcuation groove 2 at the screw thread place, the utility model is that an end is vertical, the other end is the groove of arcuation built in the groove 2 at screw thread place, the outer rim of nut body 1 is made the outer rim of band tapering, and the size of tapering x (is x＞h/2) greater than 50% of nut body 1 axial dimension h.
When installing and using, hoodle is placed the vertical place of groove 2, nut body 1 is screwed in bolt gets final product.
Because groove of the present utility model is that an end is vertical, the other end is the groove of arcuation, therefore nut body 1 can only can not reverse towards a direction rotation; The outer rim of band tapering must be used special spanner, otherwise can't install or lay down nut body, has improved the theftproof performance of nut body.
