Abstract
The utility model relates to an octagonal anti-theft nut, which belongs to a machinery part for connection. The utility model comprises a nut main body. The utility model is characterized in that one inclined groove is arranged in the octagon of the nut main body, and a cylindrical pin with a thread is arranged in the inclined groove. The utility model can be screwed on the existing bolt, the utility model has a favorable retreat stop function, and the utility model has the advantages of simple structure, convenient installation and use, good anti-theft effect, low manufacturing cost, etc.
Description
Technical field
The utility model relates to a kind of fastening piece that connects usefulness, particularly relates to a kind of octagon anti-theft nut that only advances not move back function that has, and is to the improvement of existing anti-theft bolt structure, belongs to the mechanical parts that connect usefulness.
Background technique
At present, unattended main equipment is occurred repeatedly by the example that the lawless person stealthily dismantles, the iron tower tower material that for example is arranged on open-air conveying high voltage wire is just lost seriously, and existing anti-theft bolt is just squeezed into an iron contract in the bolt shank upper shed, makes the screw spreading play the retaining effect.This method has been destroyed the zinc coat of bolt, and antitheft effect is also undesirable.
The model utility content
The purpose of this utility model is to overcome the prior art above shortcomings, and the improvement by to existing anti-theft bolt structure provides a kind of octagon anti-theft nut.This novel octagon anti-theft nut is screwed on the existing bolt shank, has played the effect of retaining, and has characteristics such as simple in structure, easy to install, good anti-theft effect and cost are low, has solved the deficiency that prior art exists.
The technological scheme that the utility model provides is: this octagon anti-theft nut, include a nut main body, and be characterized in being provided with place's skewed slot in the octagon of described nut main body, be provided with a threaded cylindrical pin in this skewed slot.
Principle of the present utility model is: when the clockwise jam-packed of nut, the threaded screw thread of screw thread pin produces friction, makes pin turn to the depths on groove inclined-plane, it is unrestricted to advance, nut protrudes the position owing to tighten extruding simultaneously, withstands pin, and it is tighter that nut is contacted with screw rod; When nut rotated counterclockwise, the threaded screw thread of the screw thread on the pin produced friction, made the shallow place rotation of pin to the groove inclined-plane, nut and screw rod are blocked and can't back off, and had played good retaining effect.
Compared with prior art, the beneficial effects of the utility model are: can be screwed on the existing bolt shank, play the effect of good retaining, and have characteristics such as simple in structure, easy to install, good anti-theft effect and cost be low.
Description of drawings
Fig. 1 provides embodiment's structural representation for the utility model;
Fig. 2 is the side sectional view of Fig. 1.
Number in the figure: 1. nut main body, 2. skewed slot, 3. threaded cylindrical pin.
Embodiment
As Fig. 1～shown in Figure 2, this octagon anti-theft nut includes a nut main body 1, is provided with place's skewed slot 2 in the octagon of nut main body 1, is provided with a threaded cylindrical pin 3 in this skewed slot 2.
When the clockwise jam-packed of nut, the threaded screw thread of screw thread pin produces friction, makes pin turn to the depths on groove inclined-plane, and it is unrestricted to advance, and nut protrudes the position owing to tighten extruding simultaneously, withstands pin, and it is tighter that nut is contacted with screw rod; When nut rotated counterclockwise, the threaded screw thread of the screw thread on the pin produced friction, made the shallow place rotation of pin to the groove inclined-plane, nut and screw rod are blocked and can't back off, and had played good retaining effect.Before use, in the middle of the nut plastic plug can be set temporarily, with fixator pins, when the nut jam-packed, this plastic plug can be ejected.
