A hinge seat for the door of a transport container

Abstract

The invention relates to the field of logistics and transportation equipment, in particular to a hinge seat for a transporting cargo box door. The hinge seat comprises a speed limiting mechanism, thespeed limiting mechanism comprises a first hydraulic cylinder, a second hydraulic cylinder and a limit cylinder which are fixed on a box body, the first hydraulic cylinder communicates with the limitcylinder through an overflow pipe, the first hydraulic cylinder and the second hydraulic cylinder are connected through a butterfly valve, the first hydraulic cylinder is horizontally and transverselyarranged and is internally provided with a first piston plate in a sliding connection manner, and a first piston rod is fixed to the first piston plate and penetrates through a guide sleeve on the box body in a sliding manner and is connected with the box door through a connecting rod in a hinged manner. By means of the hinge seat for the transporting cargo box door, when the opening speed of thebox door is too large; the interior of the limit cylinder is filled with pressure to enable the circulation amount of the butterfly valve to be reduced or closed, the first piston rod is limited, speed limiting or stopping of the box door is achieved, the safety during box door opening is ensured, a locking mechanism conducts single-direction limiting locking on a second rack to enable the box door to be incapable of closing under the external force effect after the box door is opened by a certain angle, and cargo loading and unloading are facilitated.

Description

technical field [0001] The invention relates to the field of logistics transportation equipment, in particular to a hinge seat for a door of a transportation container. Background technique [0002] The cargo box is used to store goods and facilitate the transfer of the box body. Usually, the cargo box has one or two doors that open in opposite directions. The door and the box body are connected by a hinge mechanism to facilitate opening and closing. During the transportation of the existing container, the door will be squeezed due to the scattered items in the box due to the bumpy road, so that the door is subjected to the outward force exerted by the internal goods, or the door is subjected to its own gravity when the road surface is uneven. At this time, due to the release of the locking force on the door, the force exerted by the goods on the door and the acceleration of the door's own weight will do work on the door, which makes the opening speed of the door suddenly in...

Problems solved by technology

During the transportation of the existing container, the door will be squeezed due to the scattered items in the box due to the bumpy road, so that the door is subjected to the outward force exerted by the internal goods, or the door is subjected to its own gravity when the road surface is uneven. At this time, due to the release of the locking force on the door, the force exerted by the goods on the door and the acceleration of the door's own weight will do work on the door, which makes the opening speed of the door suddenly increase. It is very unsafe. In view of this, we propose a hinge seat for the door of the transport container
