Two-lock device

Abstract

The invention discloses a two-lock device. The two-lock device comprises a housing, wherein a transverse mounting slot and a longitudinal mounting slot which can be blocked and mounted in needed positions are separately formed in the two ends of the housing; a lock part capable of moving back and forth is movably arranged in the housing; a locking mechanism capable of locking the lock part to movefront and rear is movably arranged in the housing in a penetrating mode; and an unlocking mechanism which can extend into the housing and can press the lock part to move is movably arranged on the left side wall surface of the housing in a penetrating mode. According to the two-lock device disclosed by the invention, an L-shaped column jacks the lock part, so that the lock part cannot be independently moved by the unlocking mechanism, and therefore, the lock part can be stably guaranteed to lock a tube in the longitudinal mounting slot without free separating; a first pressing head is pressedto move the L-shaped column downwards, so that the lock part can move backwards; and the inclined surface of a jacking column extrudes the lock part for moving a slide inclined surface, so that a locking state for the tube in the longitudinal mounting slot is relieved, and therefore, safety and convenience are brought to life.

Description

technical field [0001] The invention relates to a double lock device. Background technique [0002] Nowadays, all kinds of secondary lock devices can be seen everywhere in life. The connection between various pipe fittings and supplies for infants and young children often use such connecting pieces as secondary lock. Safety and convenience, but at the same time, due to the complex structure of the existing secondary lock device, it is often prone to failure due to too many small parts during use, and the complex structure will cause a lot of difficulty in production or assembly maintenance, as well as manpower and material resources. Wear and tear, some even cannot be disassembled after failure, so the original device can only be thrown away, which causes great inconvenience to normal life and production. Contents of the invention [0003] The object of the present invention is to provide a double lock device in order to overcome the shortcomings in the prior art. [000...
