A safety lock for connecting the upper and lower shells

Abstract

The invention discloses a safety lock for connecting an upper casing with a lower casing. The safety lock comprises first locks and second locks, wherein each first lock comprises a first knob and a first lock hole; the first lock holes are located in the edge of the lower casing; the first knobs are rotationally connected with the upper casing and arranged in the first lock holes; each second lock comprises a hook head, a hook tail, a lock seat and a second knob; the lock seats are fixed on the upper casing through bolts; the second knobs are rotationally connected with the lock seats; the hook tails are fixedly connected with the second knobs; the hook heads are connected with the hook tails; and the hook heads hook the edge of the lower casing. During locking, the upper casing and the lower casing are closed, and then the first lock and the second lock are tightened respectively; and the unlocking process and the locking process are contrary. The safety lock has the advantages of ensuring that the upper casing and the lower casing can be connected and released reliably, solving the problem that the upper casing and the lower casing are easily slip off a simple buckle and separated from each other in a using or lifting process, and having the characteristics of reasonable structural layout, high cooperation accuracy of mechanisms and firm locking.

Description

technical field [0001] The invention relates to the field of locks, in particular to a safety lock for connecting upper and lower housings, which is applied to frequently opening and closing cabinets. Background technique [0002] Many container products need to open and close the box regularly. For example, the underwater cleaning robot must open the shell after a period of use to clean up the garbage compartment inside the machine. Traditionally, a snap-on lock structure with a simple structure is used to connect and lock the upper and lower shells. , but the recovery force gradually weakens after repeated use, until a slight pull will make the upper and lower shells break free from the restriction of the snap-on lock. The upper and lower shells were separated by mistake. Therefore, the market needs a lockset suitable for upper and lower separable housings, which can ensure the reliable connection of the upper and lower housings.
