Abstract

The utility model discloses an accessory spring in a lock hole of a coded lock, which comprises an outer ring spring and an inner ring spring; the outer ring spring comprises an outer ring lower end face ring, a tower spring spiral body and an outer ring upper end face ring which are sequentially connected from bottom to top; the inner ring spring is a cylindrical spring with the height smaller than that of the outer ring spring, and the outer diameter of the end face is smaller than the inner diameter of the end face ring on the outer ring; the lower end face ring of the outer ring is a non-closed ring with a notch, and the notch is inwards connected with the lowest circle of the inner ring spring positioned in the same plane through an arc-shaped connecting rod; the axial leads of the outer ring spring and the inner ring spring are superposed; the outer ring spring, the inner ring spring and the arc-shaped connecting rod are of an integrated structure. The outer ring spring and the inner ring spring are of an integrated structure, so that the elastic strength of the spring is improved, meanwhile, the integrated structure is simpler to mount compared with two independent springs, the stability is better, the strength and the durability of the spring can be improved due to the design of the inner spring and the outer spring, and the service life of the spring is prolonged.

Description

Fitting spring in coded lock lockhole

Technical Field

The utility model belongs to the technical field of spring accessories, and particularly relates to an accessory spring in a lock hole of a coded lock.

Background

In the structure of trick lock, the spring is the part that must be used, and along with people experience the use of trick lock and the pursuit of function, the structure of trick lock is also more and more complicated to the trick lock body type is littleer and more, and under the condition that the trick lock lockhole diminishes, the spring model also diminishes, to generally using under the condition of single spring at present, appears spring strength not enough easily, therefore influences the life of whole trick lock.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems and provides a fitting spring in a lock hole of a coded lock, which is an integrated structure consisting of an inner ring spring and an outer ring spring, and is beneficial to increasing the strength and durability of the spring, prolonging the service life of the spring and the like.

The utility model is realized by the following technical scheme.

A part spring in a lock hole of a coded lock comprises an outer ring spring and an inner ring spring; the outer ring spring comprises an outer ring lower end face ring, a tower spring spiral body and an outer ring upper end face ring which are sequentially connected from bottom to top, the outer diameter of the tower spring spiral body gradually decreases from bottom to top, and the outer diameter of the lowest section is smaller than that of the outer ring lower end face ring; the inner ring spring is a cylindrical spring with the height smaller than that of the outer ring spring, and the outer diameter of the end face is smaller than the inner diameter of the end face ring on the outer ring; the lower end face ring of the outer ring is a non-closed ring with a notch, and the notch is inwards connected with the lowest circle of the inner ring spring positioned in the same plane through an arc-shaped connecting rod; the axial leads of the outer ring spring and the inner ring spring are superposed; the outer ring spring, the inner ring spring and the arc-shaped connecting rod are of an integrated structure.

Further, the pitch of the inner ring spring is smaller than that of the tower spring spiral body.

Furthermore, the height ratio of the outer ring spring to the inner ring spring is 2: 1-3: 1.

Further, the central angle corresponding to the circular arc of the lower end face of the outer ring is larger than 270 degrees.

The utility model has the beneficial effects that: the spring designed by the utility model comprises the outer ring spring and the inner ring spring, and the outer ring spring and the inner ring spring are of an integrated structure, so that the elastic strength of the spring is favorably improved.
