Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a vertical tail plate device with a chain mounted on the transmission mechanism. Background Technology

[0002] Traditional chain-driven vertical tailgates have limited lifting height due to the location of the transmission mechanism. By placing the transmission mechanism at the top, the lifting height of the vertical tailgate can be greatly increased, allowing it to be applied in more scenarios and expanding the market.

[0003] Meanwhile, the traditional vertical tailgate design limits the lifting height, making it difficult to adapt to more needs and applicable to more scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a chain-type vertical tailplate device with an upper transmission mechanism, which solves the problem that the lifting height of the vertical tailplate in the prior art is limited, making it difficult to adapt to more needs and apply to more scenarios.

[0005] To achieve the above objectives, this utility model employs a vertical tailplate device with an upper chain-driven transmission mechanism, comprising a column assembly, a lower crossbeam, a large plate, a lifting arm, a connecting car upper beam, a chain drive component, and a large plate connecting support. The lower crossbeam is located in the middle of the column assembly, the connecting car upper beam is located at the top of the column assembly, the chain drive component is located inside the connecting car upper beam, the lifting arm is connected to the chain drive component, and the large plate is hinged to the lower end of the lifting arm and cooperates with the large plate connecting support.

[0006] The transmission mechanism with a chain-type vertical tail plate device also includes a limiting member, which is located at the top of the column assembly.

[0007] The transmission mechanism with a chain-type vertical tail plate device also includes square steel, and the square steel is provided at the connection between the lower crossbeam and the column assembly.

[0008] The column assembly includes a front column and a rear column. The rear column is fixedly connected to the front column and is located on the outer side wall of the front column. The lower crossbeam and the connecting carriage are respectively connected to the front column.

[0009] The transmission mechanism with a chain-type vertical tail plate also includes aluminum guardrails, with the aluminum guardrails installed at both ends of the large plate.

[0010] The transmission mechanism with a chain-type vertical tail plate also includes multiple anti-collision blocks, each of which is fixedly connected to the large plate and located on the outer side wall of the large plate.

[0011] This utility model discloses a vertical tailplate device with an upper chain-driven transmission mechanism. The lower crossbeam is located in the middle of the column assembly and is flush with the carriage floor. The chain drive pulls the lifting arm, thereby moving the lifting arm upward on the column assembly. The large plate can be lifted, achieving the effect of adapting to more needs and being applicable to more scenarios. Attached Figure Description
