Description

Technical Field

[0001] This utility model relates to the field of pickup truck tail box lifting technology, specifically a lifting device for pickup truck tail boxes. Background Technology

[0002] Pickup trucks are often used to carry heavy goods, which makes moving and transporting the goods inconvenient. Therefore, lifting devices are needed to assist workers in moving the goods, thereby saving workers' physical strength.

[0003] In existing technologies, loading and unloading goods is inconvenient and not conducive to user operation. Heavier objects require more time and effort to move.

[0004] To overcome the above shortcomings, the prior art (publication number CN2745832Y) discloses an automatic opening and closing lifting device for automobile cargo doors, which consists of a door panel, two sets of opening and closing lifting mechanisms, a hydraulic system, and a control circuit. The two sets of opening and closing lifting mechanisms are symmetrically arranged on the left and right. The opening and closing lifting mechanism consists of a tilting hydraulic cylinder, a lifting hydraulic cylinder, a connecting rod, and a connecting plate. The structure is reasonable and has the following beneficial effects: the cargo door can be opened to a horizontal position to form a platform for publicity and display. The cargo door can also be raised and lowered by the lifting mechanism, which facilitates the loading and unloading of goods and the getting on and off of personnel.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, after the pickup truck is loaded, it is inconvenient to store the device, and storing the lifting device is cumbersome, which is not conducive to the user's use. At the same time, the force it can bear is relatively limited during use, and it cannot provide efficient lifting. Utility Model Content

[0006] The purpose of this utility model is to provide a lifting device for the rear cargo box of a pickup truck, so as to solve the problems mentioned in the background art, such as the inconvenience of storing the device after the pickup truck is loaded, the cumbersome storage of the lifting device, the limited force it can bear during use, and the inability to provide efficient lifting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a pickup truck tail box, comprising a support and a fixing frame disposed on the inner side of the support, wherein a central telescopic connecting rod is disposed at the front end of the fixing frame, and a lifting platform is disposed at the front end of the central telescopic connecting rod; a mounting component is disposed at the rear end of the fixing frame, and a lifting mechanism is disposed at the upper end of the mounting component, wherein the lifting mechanism is disposed of a hook plate, and the rear end of the hook plate is disposed at the front end of the mounting component.

[0008] Furthermore, the rear end of the central telescopic connecting rod is rotatably connected to the fixed frame, and the front end of the central telescopic connecting rod is rotatably connected to the lifting platform, and the front end of the central telescopic connecting rod is telescopically oriented.

[0009] Furthermore, the lifting mechanism is equipped with a motor, the lower end of which is fixedly mounted on the upper end of the mounting component, and a steel cable is wound around the middle end of the motor.

[0010] Furthermore, the middle end of the steel cable is attached to the surface of the pulley, and the lower end of the pulley is fixedly installed on the upper end of the central telescopic connecting rod, and a steel hook is fixedly installed at the rear end of the steel cable.

[0011] Furthermore, the front end of the hook plate is provided with a hole, and the rear end of the steel hook engages with the hook plate.

[0012] Furthermore, a first extension member is fixedly installed at the front end of the fixing frame, and the first extension member is inclined. A side connecting rod is rotatably installed at the front end of the first extension member, and the side connecting rod is trapezoidal in shape. A second extension member is rotatably installed at the front end of the side connecting rod, and the upper end of the second extension member is fixedly installed at the bottom of the lifting platform.

[0013] Furthermore, a positioning hole plate is fixedly installed at the bottom of the lifting platform, and the lower end of the positioning hole plate is sleeved on the surface of the side connecting rod. The left and right ends of the lifting platform are fixedly installed with fixing pins by steel ropes, and the fixing pins are correspondingly set with the positioning hole plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During lifting, the fixed frame is installed through the support. The motor is installed at the rear end of the fixed frame through the mounting parts. The steel hook at the rear end of the steel cable is hung on the opening at the front end of the hook plate. With the rotation connection at its front and rear ends, the central telescopic connecting rod can rotate to drive the lifting platform. Therefore, the height of the lifting platform can be adjusted.

[0016] Furthermore, during the height adjustment of the lifting platform, a first extension and a second extension are respectively provided at the front and rear ends of the side connecting rod, and the lifting platform is rotatably connected to them. As the central telescopic connecting rod is adjusted, the height of the lifting platform can be smoothly adjusted upward, ensuring the stability of the lifting.

[0017] 2. Once the lifting platform is positioned at a vertical angle, it can be stored. At the same time, the platform is suspended on both sides by fixing pins connected by steel cables. After the lifting platform is stored vertically, the fixing pins are embedded in the positioning holes to secure the platform and prevent it from tipping over while driving.
