Abstract

The invention relates to a turnover box cover locking structure. The turnover box cover locking structure comprises a turnover box body, a box cover and cover locks; the side portion of the upper surface of the box cover is provided with sunken tables I; the tops of side plates of the turnover box body are provided with protrusions, and the protrusions are inserted in sunken tables II formed in the side portion of the lower surface of the box cover; spring bolts convexly arranged on the cover lock sequentially penetrate through the side walls of the sunken tables I and the side walls of the sunken tables II to penetrate into locking notches formed in the side walls of the protrusions; the side surfaces of the cover locks are provided with lock body strip tying holes; and the side walls ofthe sunken tables I are provided with box cover strip tying holes which communicate with the lock body strip tying holes when the sprint bolts are in the locked state. The turnover box cover locking structure has the beneficial effects that the whole locking structure is formed by combining and assembling a few parts, on the premise that stable locking is ensured, the structure is compact and simple, the parts are convenient to replace, and the maintaining cost is reduced.

Description

technical field [0001] The invention relates to a cover locking structure of a turnover box, which is applied to logistics activities of goods. Background technique [0002] The existing common structures of the turnover box and its cover lock device are: [0003] (1) A cover lock device that relies on spring action. The lid lock device relying on spring action is mainly composed of a lock body and a spring. The lock body has its own lock tongue, which is usually die-cast with non-ferrous metal zinc alloy. A compression spring is installed in the lock body, and the dead bolt in the lock body is in the locked position under standing conditions. When the lock tongue of the lock body in the cover lock device is required to be locked with the side plate of the turnover box, you need to push the hand buckle position of the lock body with your fingers. At this time, the spring in the lock body is compressed, and then release the finger, and the spring resets. , the lock tongue...
