Abstract

The utility model relates to a screw/nut, in particular to a new screw/nut which is used to fasten a wheel, closing caps of pressure containers, and vibration-oriented parts. The screw/nut comprises a primary fastening screw/nut and a secondary fastening screw/nut; wherein, the external side of the primary fastening screw/nut is provided with a cycle of fastening lock tails with opening, when the secondary fastening screw/nut which is provided with a 'V' fastening slot is fastened on the external side of the primary fastening screw/nut, the 'V' fastening slot on the secondary fastening screw/nut will make the fastening lock tails which are arranged on the primary fastening screw/nut lock the screw shaft firmly and simultaneously the secondary fastening screw/nut and the primary fastening screw/nut are locked so that the primary fastening screw/nut will not become loose due to factors such as vibration and thermal expansion, thereby realizing the purposes of fastening and locking. The utility model has the advantages of simple structure, easy manufacturing, and convenient use.

Description

A kind of screw mother

Technical field

The utility model relates to a kind of nut, mainly refers to wheel, pressurized container capping, easily a kind of screw mother of the fastening usefulness of vibration member.

Background technique

At present, fastening at mechanical part, when particularly fastening or easy plane of vibration makes the loosening parts of nut fastening at bigger mechanical part, the normal fastening means of using spring pad to add double nut, though this fastening means commonly used is simple to operate, but exist fastening poor performance, require great effort during dismounting, the normal phase is used disadvantages such as the easy slide fastener of lead screw, have in addition coping screw bar slide fastener cause unnecessary economic loss and even risk to human life.

The model utility content

In view of this, the purpose of this utility model provides a kind of manufacturing simple in structure, easy, a kind of screw mother easy to use, for the fastening of mechanical part provided convenience.

For solving the problems of the technologies described above, a kind of screw mother of the present utility model is made up of main fastening screw screw and secondary fastening screw screw, being provided with an astragal in the outside of main fastening screw screw has the fastening lock tail of opening, when the secondary fastening screw screw that is provided with V-type binding groove fastening on the outside of main fastening screw screw is solid, the firm pinning lead screw of fastening lock tail that V-type binding groove on the secondary fastening screw screw will make main fastening screw screw be provided with, and together lock with main fastening screw screw simultaneously.

Owing to adopted such scheme: main fastening screw screw can be gone up the solid secondary fastening screw screw of fastening easily and tip the row locking on can be easily, and fastening firm not slide fastener, and the while can be unclamped secondary fastening screw screw again easily, unloads main fastening screw screw.
