Locking and unlocking device of central control unit of folding bed

Abstract

A locking and unlocking device of a central control unit of a folding bed comprises the central control unit. The central control unit comprises a shell (1) and a shell cover (2), the shell cover (2) covers the top face of the shell (1), a locating column (11) is vertically arranged in the middle of an inner cavity of the shell (1), and a metal locking sheet (12) is fixed to the top of the locating column (11). A vertically-communicated through hole (21) is formed in the middle of the shell cover (2), a buckle portion (2a) capable of rotating is arranged at the bottom of the shell cover (2), and the top of the buckle potion (2a) stretches out of the shell cover (2) through the through hole (21) to be connected with a pull portion which is arranged on the upper surface of the shell cover (2) and can pull the shell cover (2) to move upwards. A torsional spring (22) is arranged on the buckle portion (2a), and when the buckle portion (2a) moves downwards, the torsional spring (22) can enable the buckle portion (2a) to automatically rotate to be buckled with the bottom face of the metal locking sheet (12). Two buckle legs (23) capable of being buckled with the corresponding side edges (13) of the metal locking sheet (12) are arranged at the bottom of the buckle portion (2a). The locking and unlocking device has the advantages of being simple in structure, safe, reliable and good in locking effect and facilitating unlocking.
