At the same time, its convenient operation also enables the staff to easily and quickly open or close the cabinet door, thereby improving the work efficiency.

[0061] The wheels are standard parts made of wear-resistant materials and have good shock absorption and anti-shake performance. The configuration of the wheels makes the cabinet body have the convenience of moving and can be flexibly adjusted according to actual needs.

[0062] The hidden handle 56 is a standard part installed at a specific position of the cabinet body, which is flush with the surface of the cabinet body at ordinary times and does not affect the integrity and aesthetics of the overall appearance of the cabinet body. When moving is needed, it can play a convenient role.

[0063] The device has a simple and elegant appearance, a compact internal structure, a reasonable space layout and effectively reduces the floor area. Its stable and reliable performance is due to the use of high-quality materials and strict manufacturing process, which can ensure the stable operation of the equipment and instruments for a long time in complex and changeable environments.

When the instrument cabinet needs to be moved, the device can be conveniently moved by pulling and simple operation.

[0073] The hinge is a standard part, which is used for connecting the back plate 8 and the cabinet body, so that the back plate 8 can be flexibly opened and closed at a certain angle.

[0074] In the scheme, the internal water circulation flow can take away part of the heat. Meanwhile, the scheme optimizes the internal layout of the cabinet body, reduces the density of the heating elements, prevents heat concentration, is beneficial to the dispersion and emission of heat, and thus abandons the traditional fan cooling mode.

[0075] Meanwhile, the main structure of the cabinet body selects a material with good toughness and rigidity, and is matched with a carefully designed connection and support mode, and is further matched with a stable chassis design, so that the vibration and shaking from all directions can be well dispersed and absorbed. The tire of the cabinet wheel adopts a special high-elasticity rubber material, and has good damping effect.

[0076] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
