Lock, transmitter and method for locking and unlocking cover body thereof

Abstract

The invention discloses a lock, a transmitter and a method for locking and unlocking a cover body of the transmitter, and aims to ensure the reliability of interlocking and unlocking between a lock body and a lock core and prevent failure of the interlocking and the unlocking between the lock body and the lock core. The lock comprises the lock body; the inside of the lock body is provided with a lock hole; the lock body is sleeved with the lock core which can rotate relative to the lock body; and the lock core is provided with a lock bolt, wherein the lock body is provided with a groove, and a first elastic rocking block is arranged at a position, which a key inserted in the lock hole can touch, on the lock core; when the first elastic rocking block rotates and presses against the groove of the lock body, the lock body and the lock core are interlocked; and when the key is inserted in place, the key extrudes the first elastic rocking block from the groove of the lock body in a rotating mode so as to remove the interlocking between the lock body and the lock core. The lock can be applied to cases, boxes, doors and the like.

Description

technical field [0001] The invention relates to a lock, in particular to a lock applied on a conveyor. Background technique [0002] Locks are widely used in daily production and life. Existing common lockset structure is substantially the same, all is made up of parts such as lock body, lock cylinder, spring, marble. Among them, the lock core is circular, and several small holes are drilled on the circular lock core, and then the same number of small holes with the same caliber are drilled at the position of the lock body corresponding to the small holes of the lock core. . The effect of small hole is to be used for loading marble and spring. The small hole on the lock body is used to hold the pin and the spring, and the hole on the lock cylinder is called the pin hole. The function of the marble is to block the lock cylinder, so that the lock cylinder and the lock body are interlocked, and the lock cylinder cannot be rotated casually. [0003] In the existing lock str...

Problems solved by technology

When the lock is exposed to the sun and rain for a long time in the open air or used for a period of time in a place with a lot of dust, there will be rust in the small hole or be polluted by dust, which will hinder the normal sliding of the pins, thus making the lock The interlocking or unlocking between the lock body and the lock cylinder fails, and the requirements for machining accuracy and assembly cost are high
