Turnover box based on corner lock fastening

Abstract

The invention discloses a turnover box based on corner lock fastening. The turnover box comprises a hollow box body (8) composed of six box plates, and the adjacent box plates of the hollow box body (8) are in fastening connection by corner locks (1). The corner locks (1) include L-shaped locking pieces (101) disposed at corners of the hollow box body (8), straight locking pieces (102) on the boxplates adjacent to the corner positions in which the L-shaped locking pieces (101) are located and locking bars (103) connecting the L-shaped locking pieces (101) with the straight locking pieces (102). The turnover box can effectively avoid that in a limited space such as a container or a car box, fasteners on both sides of two adjacent turnover boxes often rub each other, and damage to the box plates and the fasteners is further avoided. During the transportation, a box cover and a box bottom of a box can be completely locked, and the condition that pollution or loss of liquid or solid cargos transported inside the box is caused due to the fact that the box cover is opened manually or non-manually is avoided.

Description

technical field [0001] The invention relates to a new type of turnover box for transportation, more specifically, to a turnover box based on corner lock fastening. Background technique [0002] The non-demolition and zero turnover box in the prior art is a box body composed of six box panels. After the six box panels of the box body are connected by connectors at the edge junctions, a hollow box is formed. For accommodating and transporting liquid or solid packages, the connecting parts are all connected by L-shaped hooks and locks. In the prior art, when the L-shaped lock hook and the lock buckle are connected together, the width of the box body in the front, rear, left and right directions will be increased. [0003] When this kind of turnover box is used for side-by-side packing or unloading of containers or automobiles, due to the limited space, the two adjacent turnover boxes need to be very close. The thickness of the above-mentioned L-shaped lock hook itself is more ...
