Semi-automatic pilot pin door hinge

Abstract

The invention discloses a semi-automatic pilot pin door hinge, and specifically relates to a door hinge on a door sheet of a container of a freight vehicle. According to the semi-automatic pilot pin door hinge, a vehicle door hinge and a semi-automatic fixing device for the opened door sheet of the container of the freight vehicle are designed integrally by using hot forging and semi-hot forging machining processes. The semi-automatic pilot pin door hinge takes the place of a device for fixing the opened door sheet of the container of the freight vehicle by using a hanging fastener, and the problem of easy happening of industrial accidents in a stamping production process of such a hanging fastener is solved, and so is the problem that the hanging fastener mounted on the door sheet is difficult to align to and insert in bayonets in side surfaces of a body of the container when the door sheet of the container is fixed after being opened due to that such a hanging fastener is weak in mechanical strength and easy to deform under an external force in actual use; besides, as the vehicle door hinge and the fixing device for the opened door sheet of the container of the freight vehicle are designed integrally, resources are saved and the production cost is reduced; moreover, an innovative design of semi-automatic fixation after the door sheet of the container is opened is realized.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a container of a truck and a door hinge on a door panel of the container. Background technique [0002] At present, the function of the door hinges used on the container door panels of containers and light-duty box trucks only plays the role of opening and closing the door and rotating the support left and right. When the container or container is loading and unloading goods, it is necessary to open and fix the door panel of the container or container to prevent the door panel from swinging left and right, which will affect the cargo loading and unloading operation and bring potential safety hazards. Therefore, the staff will insert the hanging buckle installed on the cargo box door panel into the bayonet socket installed on one side of the truck box body to play the role of fixing the cargo box door panel so that the door panel will not swing left and right. Although the desig...

AI Technical Summary

Problems solved by technology

Although the design of this hanging buckle can play the role of fixing the container and container door panels on one side of the box after opening, because the hanging buckle and the bayonet are all stamped parts processed by cold-rolled plate with stamping process, Due to the external force in use, the hanging buckle will be deformed after a long time of use, which makes it difficult for the hanging buckle installed on the door panel to align with the bayonet installed on the container body, and it is difficult and cumbersome to fix the door panel Work-related accidents are prone to occur during the forming process, and the assembly of hanging buckles increases production costs, etc.
