Side wall locking mechanism and container

Abstract

The invention discloses a side wall locking mechanism and a container. The side wall locking mechanism comprises a first driving mechanism, a pressing plate and a limiting base. The pressing plate is connected with a first driving mechanism which can drive the pressing plate to rotate; the limiting seat is used for limiting a spring bolt on the side wall of the container; when the pressing plate rotates to the locking position close to the limiting base, the pressing plate and the limiting base can clamp the spring bolt, and when the pressing plate rotates to the unlocking position away from the limiting base, the spring bolt is allowed to leave the limiting base. By arranging the side wall locking mechanism capable of being automatically opened and closed, the opening and closing speed of the side wall is increased, and the loading and unloading efficiency of the container is improved.

[0086] The pressing plate 203 rotates to a locking position close to the limiting seat 204 , and the pressing plate 203 and the limiting seat 204 can clamp the first locking tongue 131 . The pressing plate 203 rotates to an unlocking position away from the limiting seat 204 , allowing the first locking tongue 131 to leave the limiting seat 204 .

[0087] The rotation stroke of the pressing plate 203 is an obtuse angle, and when in the unlocking position, the first locking tongue 131 is not prevented from leaving the limiting seat 204 .

[0088] like Figure 1 , Figure 2 As shown, the side wall is closed, and the pressing plate 203 rotates to a locking position close to the limiting seat 204. Figure 4 , Figure 5 As shown, the side wall is opened, and the pressing plate 203 rotates to an unlocking position away from the limiting seat 204 .
