Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a double opening mechanism for a rear door of a cargo compartment of a dump truck. Background Art

[0002] At present, the structure of the rear door opening mechanism of the dump truck is that the upper hinge mechanism is connected to the rear door, and the lower lock hook locks the rear door. When lifting, the lock hook is loosened by gravity, and the rear door and the cargo box are opened at a certain angle for unloading.

[0003] The utility model patent with authorization announcement number CN209700476U discloses a double opening mechanism for the rear door of the cargo compartment of a dump truck, including a cargo compartment side panel and a cargo compartment rear door, a rotating lock mechanism between the upper part of one side of the cargo compartment rear door and the adjacent cargo compartment side panel, and a double hinge mechanism between the upper part of the other side of the cargo compartment rear door and the adjacent cargo compartment side panel. The rotating lock mechanism and the double hinge mechanism cooperate to realize the dual functions of opening the cargo compartment rear door sideways or flipping the cargo compartment rear door backwards to open.

[0004] The advantages of this utility model are that it has the advantages of simple structure, easy installation and maintenance, easy use and low production cost. The rear door opening mode can be quickly switched through the cooperation of the rotating lock mechanism and the double hinge mechanism. This dual-function rear door opening mode allows users to choose more types of goods to load, makes loading more flexible, and improves economic benefits.

[0005] However, after actual application by technicians in this field, it was found that the above method still has some disadvantages. The rear door opens sideways to expand the lateral range and is suspended in the air, which may cause others to accidentally hit their heads and cause personal injuries. At the same time, when dumping the goods, the goods cannot slide smoothly and are easily piled up and blocked between the cargo box and the rear door. Utility Model Content

[0006] The purpose of the utility model is to provide a double opening mechanism for the rear door of the cargo box of a dump truck. By arranging a connecting component, a shielding component, a rotating component and a sliding component, the utility model solves the problem proposed in the above background technology that the rear door opens sideways to expand the lateral range and is suspended in the air, which may cause others to accidentally collide with the head and cause personal injury to others. At the same time, when dumping the goods, the goods cannot slide smoothly and are easily accumulated and blocked between the cargo box and the rear door.

[0007] To achieve the above purpose, the utility model is implemented by the following technical scheme: comprising a cargo compartment, the edges of both sides of the cargo compartment are fixedly connected with connection components, one end of the connection component is rotatably connected with a shielding component, the upper surface of the shielding component is fixedly connected with a rotating component, and the front surface of the shielding component is fixedly connected with a sliding component;

[0008] The connecting assembly includes a buckle, one end of which is fixedly connected to the edge of one side of the cargo compartment, the outer surface of the buckle is overlapped with a hook, one side of the hook is rotatably connected to a spring, and the other side of the hook is rotatably connected to one end of the outer surface of the shielding assembly.

[0009] Furthermore, the shielding assembly includes a balance plate, one side of the balance plate is rotatably connected to one end of a spring, the upper surface of the balance plate is fixedly connected to a connecting ring, the interior of the connecting ring is rotatably connected to a rotating rod, and the outer surface of the rotating rod is rotatably connected to a baffle near the edge of the connecting ring.

[0010] Furthermore, the rotating assembly includes a connecting block, the lower surface of which is fixedly connected to the upper surface of the baffle, a through groove is opened on one side of the connecting block, a plug is inserted into the inside of the through groove, and a fixed block is inserted into the outer surface of the plug near the edge of the connecting block.

[0011] Furthermore, the sliding assembly includes a connecting plate, the back side of which is fixedly connected to the front surface of the baffle, a circular groove is provided on one side of the connecting plate, a connecting rod is fixedly connected to the inside of the circular groove, and a roller is rotatably connected to the outer surface of the connecting rod.

[0012] Furthermore, a blocking assembly is fixedly connected to the middle of both sides of the cargo compartment, and one end of the blocking assembly is rotatably connected to a vertical plate.

[0013] Furthermore, the blocking assembly includes a hinge, the lower part of one side of the hinge is fixedly connected to the middle part of one side of the cargo compartment, the upper part of one side of the hinge is fixedly connected to a blocking plate, the edge of one side of the blocking plate is fixedly connected to a hook, and the upper surface of the hook is overlapped with a blocking rod.

[0014] Furthermore, a blocking rod is fixedly connected to the edge of the lower surface of the cargo compartment, and the back surface of the blocking rod is overlapped with the front surface of the balance plate.

[0015] The utility model provides a double opening mechanism for the rear door of a dump truck cargo compartment, which has the following beneficial effects:

[0016] 1. By setting the connecting assembly, shielding assembly and rotating assembly, the card hook is turned in the opposite direction of the buckle to a suitable angle. Under the tension of the spring, the card hook and the shielding assembly will be parallel. At this time, the connecting block is rotatably connected with the fixed block through the bolt, so that the shielding assembly can be flipped upward to dump the goods, or the bolt is pulled out, and the balance plate is pushed on the resisting rod. The balance plate and the resisting rod support the lower surface of the card hook at the same time, and the spring pulls it, so that the baffle can be flipped downward through the rotating rod, which improves the flexibility of cargo loading and avoids the rear door being suspended in the air, causing others to accidentally hit their heads and cause personal injuries.

[0017] 2. Through the sliding assembly, when the goods are dumped backwards, the roller can reduce the friction between the goods and the box door, making the dumping smoother and avoiding the accumulation of goods between the cargo compartment and the rear door. BRIEF DESCRIPTION OF THE DRAWINGS
