Semi-automatic bolt

Abstract

The invention discloses a semi-automatic bolt, and particularly relates to the semi-automatic bolt used for fixing a container door. According to the semi-automatic bolt, the problem that left-right swing of a door sheet of a container brings about potential safety hazards during loading and unloading of cargos is avoided. Before operation, a mortise lock on the container door is usually insertedinto a bayonet in one side of a container body to fix the container door; however, the mortise lock and the bayonet are prone to deformation after used for a long time, so that inserting the mortise lock on the container door into the bayonet in the container body is difficult when the container door is fixed. The semi-automatic bolt is assembled on a fixed hinge body of a hinge on the container door, the bolt is extruded by the inclined end face of a movable hinge body of the hinge by utilizing the acting force generated when the container door is opened, a spring which is arranged on the bolt in a sleeving mode generates tension so that the bolt can be automatically inserted into a lock hole in the movable hinge body of the hinge, and therefore the container door is fixed.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a semi-automatic pin for fixing the door of a container or a container. Background technique [0002] When the container or container is loading and unloading goods, it is necessary to open and fix the container door or container door to prevent the door panel from swinging left and right, avoiding affecting the loading and unloading of goods and bringing potential safety hazards. Therefore, before the operation, the staff will insert the 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 from side to side. Although this design can play the role of fixing the container and the door panel of the container on one side of the box after opening, because the hanging buckle and the bayonet are all stamped parts processed by cold rolling pla...

Problems solved by technology

Although this design can play the role of fixing the container and the door panel of the container on one side of the box after opening, because the hanging buckle and the bayonet are all stamped parts processed by cold rolling plate with stamping process, the hanging buckle is in the In long-term use, it will be deformed due to external force for a long time. When the door panel of the container or container is fixed after opening, it is difficult to align the buckle installed on the door panel and insert it into the bayonet installed on the box body of the container. It is difficult to fix the door panel. and cumbersome
