However, as the operating speed of transportation tools is getting higher and higher, the accuracy of manual control cannot meet the accuracy requirements. At the same time, during its use, under the influence of external pressure for a long time, it is prone to deformation and depression, does not have the function of strengthening structural stability, and if not repaired in time, it is prone to major accidents;

[0004] To overcome the above defects, in the prior art 1 (a Chinese patent with the application number CN202322016739.9 and the application date of July 30, 2023), a high - precision aluminum profile for rail transit is provided. Two guiding connectors are respectively and cooperatively installed in the hollow cavity of the base. The inner ends of the guiding connectors are opposed to each other, and the outer ends of the guiding connectors respectively extend out of the base and are used for positioning and connecting the bases of adjacent aluminum profiles to achieve high - precision positioning and installation of adjacent aluminum profiles;

[0005] During the use of the above device, it is impossible to make the device be rapidly assembled, which increases the time spent on assembly, greatly reduces the work efficiency, and at the same time cannot meet the strength requirements of the device, resulting in stress concentration generated during the operation of the device to damage the device.

[0006] In view of the above problems, there is an urgent need to innovate on the basis of the original high - precision aluminum profile for rail transit. Content of the Utility Model

Meanwhile, a connecting plate is fixedly connected inside the multi-chamber profile body;

[0011] A telescopic block is movably connected inside the connecting plate;

[0012] An installation groove is provided on the upper surface of the multi-chamber profile body.

At the same time, the first spring plays a role in buffering and shock absorption, reducing the vibration generated when the two devices are separated.

[0023] Furthermore, a sealing gasket is installed on the upper surface of the installation groove, effectively preventing dust, moisture, impurities, and external substances from entering the inside of the installation groove, extending the service life of the device.

[0024] (3) For the high-strength multi-cavity profile for rail transit that facilitates quick assembly, the second spring can make the force transmission more stable, avoiding the stress concentration phenomenon caused by rigid connection, thereby improving the load-bearing capacity and service life of the profile.

[0036] It further includes:

[0037] Connection grooves 3 are opened on both sides of the multi-chamber profile body 1, a fixing groove 4 is opened on the surface of the multi-chamber profile body 1, and the fixing grooves 4 are symmetrically distributed about the center of the multi-chamber profile body 1. At the same time, a connecting plate 5 is fixedly connected inside the multi-chamber profile body 1, a telescopic block 6 is movably connected inside the connecting plate 5, and an installation groove 9 is opened on the upper surface of the multi-chamber profile body 1.

[0038] The connecting plate 5 is installed on both sides of the multi-chamber profile body 1, and the telescopic block 6 is installed at the end of the connecting plate 5, which shortens the time required for the device during assembly. At the same time, a main cavity groove 15 is opened inside the multi-chamber profile body 1. When the main cavity groove 15 bears an external force, it can disperse the force through its own structural deformation. And the auxiliary cavity groove 2 improves the stability of the device and effectively reduces the deformation caused by stress concentration.

[0039] Embodiment 2. In this embodiment, different from Embodiment 1, by setting the connection of the sliding groove 10, the first spring 12 and the moving column 11, the multi-chamber profile body 1 can be quickly separated from the adjacent multi-chamber profile body 1, as Figures 4-5 shown:

[0041] When it is necessary to disassemble the two multi-cavity profile bodies 1, the first spring 12 inside the multi-cavity profile body 1 will push the moving column 11 to move towards the outside of the multi-cavity profile body 1, enabling the multi-cavity profile body 1 to be quickly separated from the adjacent multi-cavity profile body 1. At the same time, the first spring 12 plays a role in buffering and shock absorption, reducing the vibration generated when the two devices are separated. In addition, a sealing gasket 7 is installed on the upper surface of the installation groove 9, effectively preventing dust, moisture, impurities, and external substances from entering the inside of the installation groove 9, and extending the service life of the device.
