Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] According to the embodiment of the present utility model, a height-adjustable support device is provided. Please refer to Figures 1 to 13, including: a support frame 1; an adjustment plate 2, the adjustment plate 2 is connected to the support frame 1 and is movably arranged relative to the support frame 1. Move the adjustment plate 2 to adjust the height of the adjustment plate 2. The adjustment plate 2 includes a first adjustment plate 21, a second adjustment plate 22 and a third adjustment plate 23. The first adjustment plate 21 and the second adjustment plate 22 are in the same plane, and the third adjustment plate 23 is located at the connection of the first adjustment plate 21 and the second adjustment plate 22. The third adjustment plate 23 is perpendicular to the first adjustment plate 21 and the second adjustment plate 22, thus forming a T-shaped structure; an adjustment assembly 3, the adjustment assembly 3 includes a fixing member 31. Move the adjustment plate 2 and fix the adjustment plate 2 on the support frame 1 through the fixing member 31. Through the T-shaped structure formed by the combination of the first adjustment plate 21, the second adjustment plate 22 and the third adjustment plate 23 on the support frame 1, the overall structure of the device is more stable and can withstand greater vertical and lateral loads. This design is particularly suitable for scenarios where heavy equipment or pipelines need to be supported, such as chillers, etc. The movable design between the adjustment plate 2 and the support frame 1 allows users to easily adjust the height of the adjustment plate according to actual needs, which not only facilitates the installation and debugging process, but also can adapt to the support requirements of different heights and angles, improving the adaptability and practicality of the device. The height-adjustable support device of this embodiment solves the technical problem that the connection pipe between the chiller and the outside in the related art cannot bear heavy loads and is easily broken.

[0038] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , for the height-adjustable support device of this embodiment, the support frame 1 includes a first support plate 11 and a second support plate 12. The first support plate 11 is perpendicular to the second support plate 12. The first adjustment plate 21 and the second adjustment plate 22 are both arranged on the first support plate 11, and the third adjustment plate 23 is arranged on the second support plate 12. The perpendicularly intersecting first support plate 11 and second support plate 12 form a stable support foundation, providing strong support force for the entire device. The first adjustment plate 21 and the second adjustment plate 22 are arranged on the first support plate 11 and can move along the length direction of the first support plate 11 respectively to adjust their heights. The third adjustment plate 23 is arranged on the second support plate 12 and forms a T-shaped structure with the first and second adjustment plates, which not only ensures the stability of the structure but also provides additional adjustment flexibility. By adjusting the positions of these three adjustment plates, users can precisely control the height and position of the support points to meet the requirements in different scenarios.

Each first through-hole 32 and each second through-hole 33 are arranged in a one-to-one correspondence, so that the fixing member 31 passes through the first through-hole 32 and the second through-hole 33 in sequence, thereby connecting the support frame 1 and the adjustment plate 2. By passing the fixing member 31 through the one-to-one corresponding first through-hole 32 and second through-hole 33 in sequence, a firm connection between the support frame 1 and the adjustment plate 2 can be ensured.

When the adjustment plate 2 moves relative to the support frame 1, the slider 35 moves in the slide groove 34. The slide groove 34 is respectively arranged on the first support plate 11 and the second support plate 12, providing a stable track for the movement of the adjustment plate 2. The movement of the slider 35 in the slide groove 34 enables the adjustment plate 2 to be smoothly adjusted in height relative to the support frame 1.
