Hinge device and folding container with same

Abstract

The invention provides a hinge device and a folding container with the same. The hinge device comprises a fixed hinge, a movable hinge and a locking mechanism. The movable hinge is pivotally connectedto the fixed hinge between a horizontal position and a vertical position; and the locking mechanism is pivotally connected to the fixed hinge between a locking position and a releasing position, thelocking mechanism comprises a bracket, a handle and a locking block, the bracket is pivotally connected to the fixed hinge, the handle is connected to the bracket, and the locking block is movably clamped on the bracket. In the process that the movable hinge pivots from the horizontal position to the vertical position, the movable hinge can push the locking block located at the locking position, so that the movable hinge located at the vertical position is at least partially located below the locking block located at the locking position; and in the process that the movable hinge pivots from the vertical position to the horizontal position, the locking block blocks movement of the movable hinge, and the handle is configured to be operable to enable the locking block to rotate from the locking position to the releasing position so as to allow the movable hinge to pivot to the horizontal position.

Description

technical field [0001] The invention relates to the technical field of containers, in particular to a hinge device and a folding container with the hinge device. Background technique [0002] In the current folding container, the foldable end frame is hinged to the bottom frame through a hinge device, and after the end frame is erected, the latch of the hinge device needs to be manually operated to lock the end frame. The hinge device generally includes a movable hinge fixed to the lower end of the end frame, and a fixed hinge fixed to both sides of the end of the bottom frame. The movable hinge is hinged to the fixed hinge through a pin shaft, so that the container end frame can be folded on the bottom frame The folded position and the open position in the vertical direction enable flipping. When the end frame of the container is in the open position, the operator inserts the pin from the inside of the fixed hinge into the corresponding hole or gap of the movable hinge and...

Problems solved by technology

However, in some cases, the operator may forget to lock the latch in the correct position, and it is difficult for the operator to find out because the latch is in the outer contour plane of the box when it is opened and locked.

If the pin of the hinge device is not locked in the correct position, there will be a great safety hazard to the personnel, box body, cargo and equipment operating the box body when the operator operates the foldable container

[0004] In order to solve the above problems, the patent application with the publication number CN110406820A discloses a hinge device. Although it can solve the above problems, it still has the following deficiencies: (1) In order to ensure the tight locking between the movable hinge and the fixed hinge, when locking At the same time, the gap between the lock block and the fixed hinge and the movable hinge is small. In order to ensure the smooth operation of the lock block when it is turned over with the pin shaft of the bracket, the lock block needs to be movable and clamped on the bracket. At the same time, it can also turn around itself; however, in order to move the locking mechanism to the release position, the locking mechanism is provided with a pull ring, which is directly pivoted on the lock block. When the pull ring is manually pulled up for operation, the lock block It will not be able to turn around itself, and the lock block will be clamped, and the opening operation of the lock block will be greatly affected, and even cannot be operated; (2) the bracket includes side plates and end plates connecting side plates, side plates and The contact surface between the end plate and the lock block is an outwardly protruding arc surface, so as to realize the movable clamping between the lock block and the bracket, which is equivalent to that the lock block accommodation groove is processed by two parts of the bracket and the end plate, and the processing cost , Difficulty, many processes
