Abstract
The utility model relates to a bolt formula detach -proof nut is sold by the stopping of nut body and components of a whole that can function independently setting and constitutes, on the screw inner wall of nut body the axial offered at least one along screw screw in orientation by shallow and dark cross -section is curved straight flute, the axial both ends of straight flute are run through, stopping round pin is for cylindrical, stopping round pin diameter with roll and cooperate in the dark one side of straight flute, the length of stopping round pin matches with nut body height. The utility model discloses a detach -proof nut since the axial both ends of straight flute for running through the setting, consequently processing is more convenient, during the stopping round pin need not to pack into earlier the straight flute during transportation, during the use, only need screw up nut body in -process, with the stopping round pin insert in the straight flute can, so save the stopper, the cost is reduced.
Description
Technical field
This utility model relates to a kind of nut for the fastening of thread connection component, particularly to a kind of bolt-type anti-disassembling nut.
Background technology
Chinese utility model patent CN2802169Y discloses a kind of anti-assembling nut, including nut, longitudinally axially offering threadingly from shallow to deep cross section, direction on the inwall of nut screw is the straight trough of arc, and the longitudinally axial two ends of straight trough are not for running through, being provided with steel ball in straight trough, steel ball rolls with straight trough fornix position and coordinates, with straight trough tip snap-fit, in nut body screw, it is provided with a stopper, the inwall of nut body screw is radially evenly equipped with four straight troughs. Above-mentioned existing anti-assembling nut due to the structure of straight trough at longitudinally axially two ends not for running through, and in order to conveniently use and transport, addition of stopper, therefore not only process inconvenience, and add cost.
Summary of the invention
The purpose of this utility model is in that for not enough defect of the prior art, it is provided that a kind of convenient processing, bolt-type anti-disassembling nut lower in cost.
For achieving the above object, the open a kind of bolt-type anti-disassembling nut of this utility model, it is characterized in that: the retaining pin arranged by nut body and split forms, the screw inwall of described nut body axially at least offers one threadingly screw-in direction from shallow to deep cross section be the straight trough of arc, the axial two ends of straight trough are run through, described retaining pin is cylindrical, and a retaining pin diameter side roll deeper in described straight trough coordinates, and the length of retaining pin and nut body height match.
Bolt-type anti-disassembling nut of the present utility model is owing to the axial two ends of straight trough are for running through setting, therefore process more convenient, during transport, retaining pin is without being initially charged with in straight trough, during use, only need in fastening nut body process, retaining pin being inserted in straight trough, so eliminating stopper, reducing cost.
As further setting of the present utility model, the screw inwall of described nut body is arranged with two straight troughs. Taking to be arranged with two straight troughs, be then furnished with two retaining pins, during use, nut body stress ratio is more uniform, and reliability is higher.

Detailed description of the invention
As Figure 1-4, the retaining pin that this bolt-type anti-disassembling nut is arranged by nut body and split forms, the hexagon being shaped as routine of nut body or the shape of other existing nuts, nut body axially at least offers on the inwall of screw one threadingly screw-in direction from shallow to deep cross section be the straight trough of arc, the axial two ends of straight trough are run through, the bosom of straight trough is preferably in the position (such as edges and corners) that nut body wall thickness is the thickest, the impact on nut body intensity can be reduced as far as possible, described retaining pin is cylindrical, employing high-strength metal material makes, a retaining pin diameter side roll deeper in described straight trough coordinates, the length of retaining pin and nut body height match.
During in order to use, nut body stress ratio is more uniform, and reliability is higher, the screw inwall of described nut body is preferably arranged with two straight troughs, and is furnished with two retaining pins.
Claims (2)
