Abstract
The utility model relates to a lateral pin-fastening type antitheft nut, which comprises a nut body, a steel bead and a spring. The steel bead and the spring are positioned in the nut body. The lateral pin-fastening type antitheft nut is characterized in that a through hole is arranged on the lateral side of the nut body, the through hole faces outwards along the tightening direction of a close tangency of a section line, a spring connected with the steel bead is arranged in the through hole, a tightening groove which gradually deepens along the tightening direction is arranged at the inner end of the through hole, and a screw easy to be broken is arranged at the outer end of the through hole. The screw easy to be broken is a screw with a fracture zone at the neck portion. By means of the structure, the lateral pin-fastening type antitheft nut has the advantages that the spring and the steel bead are not easy to lose, and antitheft effect is good.
Description
Technical field
The utility model relates to anti-theft nut, and anti-theft nut is widely used in technical fields such as electric power, railway.
Background technique
Anti-theft nut comprises nut body and the inner anti-theft device of nut body; Have along tightening direction antitheft groove from light to dark in the nut body inboard; The steel ball that spring and spring are supporting is installed in the antitheft groove; Such steel ball and spring are placed in the groove, in links such as transportation, storage, come off easily and lose, and influence the use of anti-theft nut.
Summary of the invention
The purpose of the utility model is exactly that the sidepiece that provides a kind of spring, steel ball to be difficult for losing locks the formula anti-theft nut to above-mentioned shortcoming.
The purpose of the utility model is achieved in that a kind of sidepiece locks the formula anti-theft nut; Comprise steel ball and spring that nut body and nut body are inner, it is characterized in that: described nut body sidepiece has through hole, and through hole along the secant of the nearly tangent line that tightens direction outwardly; The spring that in through hole, has steel ball to connect; The inner end of through hole have along tighten direction from light to dark tighten groove, the outer end of through hole has easily broken screw, described easily broken screw is meant that neck has the screw of fracture zone.
The beneficial effect of the utility model is: the sidepiece of this spline structure locks the formula anti-theft nut and has that spring, steel ball are difficult for losing, the advantage of good anti-theft effect.
Description of drawings
Fig. 1 is the decomposition texture schematic representation of the utility model.
Wherein: 1, nut body 2, through hole 3, steel ball 4, spring 5, easily broken screw.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
As shown in Figure 1, sidepiece locks the formula anti-theft nut, comprises steel ball 3 and spring 4 that nut body 1 and nut body are inner; It is characterized in that: described nut body 1 sidepiece has through hole 2; Through hole 2 along the secant of the nearly tangent line that tightens direction outwardly, the spring 4 that in through hole 2, has steel ball 3 to connect, the inner end of through hole 2 have along tighten direction from light to dark tighten groove; The outer end of through hole has easily broken screw 5, and described easily broken screw 5 is meant that neck has the screw of fracture zone.
Described through hole 2 along the secant of the nearly tangent line that tightens direction outwardly, the direction that is meant through hole is a secant, and is the secant that deflection is arranged with tangent line a little, from figure, can significantly understand.
After steel ball and spring installation, turn easily broken screw, will break off at fracture zone, play the effect of sealing steel ball and spring.
