Lock core of axially-offset magnetic control steel column

Abstract

The invention provides a lock core of an axially-offset magnetic control steel column, comprising a core sleeve, a core axle, a front end cover and a rear end cover which are arranged on both sides of the core axle, a steel column marble for locking and positioning, and a marble spring, wherein the core axle and the rear end cover are respectively provided with at least one corresponding marble hole, the axis of lead marble hole is parallel to the axis of the core axle; the steel column marble and the marble spring are arranged in the marble hole; one end of the core sleeve where the front end cover is arranged is provided with an unlocking stem bin for holding an unlocking stem. The lock core disclosed in the invention has the advantages of simple structure, small total size, easy production and installation, reliable digital management, moreover, the shell of the lock core is a plastic shell, thus the lock core has low application cost and anti-theft function.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a lock core with an axially biased magnetically controlled steel column. Background technique [0002] Lock is a very important tool for people's daily life and safety production management of industrial and mining enterprises. It locks the safety locking mechanism of the door or equipment, and only opens it when it needs to be opened, and it should be locked when it does not need to be opened. For example, it is widely used in various industries such as electric power, banking, and petroleum. [0003] There is a kind of universal lock cylinder in the lock industry, such as the common triangular-shaped universal lock cylinder on the train, and the twist-lock lock cylinder of the microcomputer anti-error system in the current electric power industry or other power-related industries, all have a common deficiency. At the position, the rotating mandrel of the lock cylinder is a purel...

AI Technical Summary

Problems solved by technology

It has greatly improved the current technical situation in a certain sense, but there are still some shortcomings. The structure of the lock cylinder is relatively complicated, which requires high processing accuracy. When ensuring the flexibility of the lock, the overall size of the lock is relatively large. Large, when the equipment is applied on site, for example, the knife switches of some power equipment are not centralized, so it is not convenient to use

What's more serious is that the reliability of this type of lock cylinder is poor, and the small spherical pin inside it is more likely to fail to lock or open normally when the lock cylinder is placed horizontally.

see figure 2 , in the improved lock cylinder structure, the ball pins 20 are arranged transversely relative to the axis line of the mandrel 21, and the ball pins 20 and the locking ribs on the inner side wall of the core sleeve 22 form a locking structure, but the ball pins 20 are relatively fragile, especially in locks. When the core is placed horizontally, its reliability is too low
