It plays a vital role in logistics and transportation, providing a convenient and safe passage, especially during loading and unloading. Types of loading ramps generally include fixed loading ramps, mobile loading ramps, and adjustable-height loading ramps. Adjustable-height loading ramps are usually installed on a lifting platform and can be adjusted to accommodate different truck heights to meet the needs of various vehicle types.
[0003] In the prior art, the installation of traditional adjustable height loading ramps and lifting platforms is a fixed installation (welded or bolted connection). The installation and disassembly require the use of matching tools, which has great limitations, resulting in low installation and disassembly efficiency and inconvenience for personnel maintenance. Therefore, this application proposes a connection mechanism between the loading ramp and the lifting platform to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the shortcomings of the existing technology where the installation of the traditional adjustable height loading ramp and the lifting platform is fixed (welded or bolted), which requires the use of matching tools during disassembly and assembly, resulting in great limitations, low disassembly and assembly efficiency, and inconvenience for personnel maintenance. Therefore, a connection mechanism between the loading ramp and the lifting platform is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] The mounting components are configured in pairs and are mounted on corresponding brackets. Each mounting component is respectively matched with two corresponding rectangular blocks.
[0013] As a preferred embodiment of this utility model, an anti-slip pad is fixedly installed on the top of the boarding bridge.
[0014] As a preferred embodiment of this utility model, the bottom of the loading bridge has two sliding grooves, and the top of the mounting plate on the left side is slidably connected to the two sliding grooves respectively.
[0015] In a preferred embodiment of this utility model, four connecting plates are fixedly installed on the bottom of the mounting plate, and the top of the rectangular block is rotatably connected to two corresponding connecting plates.
[0016] As a preferred embodiment of this utility model, the installation assembly includes a dual-axis lead screw, a handle, two movable plates, and two insert rods. Slots are provided on the sides of the two rectangular blocks located on the same side that are close to each other.

[0035] There are two mounting components, which are set on the corresponding brackets 7 and cooperate with the two corresponding rectangular blocks 16 respectively.
[0036] With the above structure: by setting the movable base plate 1, the position of the loading ramp 2 can be moved, improving the flexibility of use.
