Spring lock without spring

Abstract

The invention provides a spring lock without a spring, which consists of a lock body, a lock core, a ball and a paired key. In the spring lock, a ball spring of the conventional known spring lock is removed, so the spring lock overcomes the defect of rustiness in the spring and is particularly suitable for occasions where the lock often contacts water, for example wrist strap clamp locks, which are compelled to wear continuously, of a wrist strap electronic monitoring terminal in specific people inside and outside prisons and cylindrical handcuffs in the improved known technology; more importantly, the spring lock is not provided with the ball spring, only one ball is arranged in each ball hole channel, the balls stay in the ball hole channels randomly, and the position is uncertain, so staff who know a lockset structure still cannot unlock illegally.

Description

Technical field [0001] The invention relates to a springless tumbler lock, in particular to a lockset applicable to wristband-type electronic monitoring terminals, handcuffs, instruments and meters, portable suitcases or briefcases, and belongs to the tumbler lock technology. Background technique [0002] As we all know, the core structure of the pin lock is a lock consisting of a lock body, a rotatable lock cylinder, a pin and its spring; one side of the lock body is drilled with a number of pin holes, and one or both sides of the lock core corresponding to the pin pin holes of the lock body are also drilled. There is a billiard hole, and there is a marble retaining rib in the middle. [0003] Each pin hole is assembled pin and spring according to the order of pin, pin, and spring, and then the pin pin hole of the lock body is sealed with lead-tin alloy. The function of the spring is to always push the two sections of pins against the ribs of the pins of the lock cylinder,...

Problems solved by technology

[0005] Due to the existence of the necessary pin spring, the pin lock of the known technology has its disadvantages: on the one hand, because the spring is easy to rust, it cannot be used in occasions that are often exposed to water; The personnel of the pin lock structure can use simple tools to detect the position of the interface between the two pins in each pin hole and the interface between the lock body and the lock cylinder, and then can open the lock without a special key; moreover, in a The billiard hole must use two or more marbles, and it is impossible to use one marble, but the pinhole with only one marble has extremely strong encryption
