The invention discloses a square cabin tail door opening and closing mechanism. The square cabin tail door opening and closing mechanism is mainly composed of a side wall, a hydraulic cylinder, a t-shaped crank rod, a crank rod and a tail door, wherein the tail door is hinged to the side wall, the two ends of the main body section of the t-shaped crank rod are respectively hinged to the crank rodmounting base on the side wall and the crank rod, the two ends of the crank rod are respectively hinged to the crank section of the t-shaped crank rod and the crank rod mounting base on the tail door,the two ends of the hydraulic cylinder are respectively hinged to the cylinder body mounting seat on the side wall and the outer extending section of the t-shaped crank rod, and the t-shaped crank rod (4) and the crank rod (9) form a v-shaped structure. According to the square cabin tail door opening and closing mechanism ,the stroke utilization rate of the hydraulic cylinder is improved, and thesingle-stage hydraulic cylinder can be used for driving the tail door to complete the 270-degree opening and closing action.
Description
technical field [0001] The invention relates to the field of machinery and structure, in particular to a shelter tailgate opening and closing mechanism. Background technique [0002] In recent decades, the manual opening and closing method of shelters no longer meets the increasing user experience requirements, and the existing automatic opening and closing mechanisms of shelters are limited by the mechanism layout and actuator technology level, and cannot open at a large angle. combined, which in turn affects the entry and exit of objects inside the shelter, limiting the transport capacity of the shelter. Therefore, there is a need for a mechanism capable of opening and closing the shelter door at a large angle, so as to expand the opening and closing angle of the shelter door and improve the use function of the shelter without reducing the user experience. Contents of the invention [0003] The invention provides a shelter tail door opening and closing mechanism, which ...
