The hexagonal bolt 402 is threadedly connected to the outer side of the fixed bracket 401, and the hexagonal bolt 402 is threadedly connected to the support plate 302.

[0023] The above scheme is adopted: through the setting of the fixed base 301, the support plate 302 can be fixedly connected to the lifting platform 1, thereby increasing the stability of the connection structure; through the setting of the support plate 302, it is convenient to install the slide groove 303, the rectangular groove 304 and the limit plate 305; through the setting of the slide groove 303 and the rectangular groove 304, it is convenient for the mounting plate 203 to move up and down therein; through the setting of the limit plate 305, the up and down movement of the mounting plate 203 can be limited to prevent it from shifting or offsetting during the movement; through the setting of the fixed bracket 401 and the hexagonal bolt 402, it is convenient to fix the support plates 302 on both sides to avoid shaking of the support plates 302 on both sides when adjusting the up and down height of the CNC machine tool.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The mounting mechanism 5 includes a plum bolt 501 and a gasket 502. The plum bolt 501 is threadedly connected to the inner side of the mounting plate 203. The gasket 502 is movably connected to the outer side of the mounting plate 203. The gasket 502 penetrates the plum bolt 501 and is threadedly connected. The moving mechanism 6 includes a movable bracket 601, a fixed shaft 602, a movable caster 603 and a locking plate 604. The movable bracket 601 is movably connected to the bottom of the lifting platform 1.

Through the setting of the gasket 502, it is convenient to increase the friction between the plum bolt 501 and the mounting plate 203, so that the fastening effect of the installation is more prominent. At the same time, the threaded connection method is convenient for disassembly, cleaning and maintenance of the CNC machine tool. Through the setting of the movable bracket 601, it is convenient to install the fixed shaft 602, the movable caster 603 and the locking plate 604. By being able to adjust the angle and direction of the movable caster 603 when moving, By setting the fixed shaft 602, the mobile caster 603 can rotate on its surface, which provides stable supporting force on the one hand and improves the convenience of rotating the mobile caster 603 on the other hand. Through the setting of the mobile caster 603, the CNC machine tool can be conveniently adjusted and arranged in the workshop to meet different production needs. When the CNC machine tool needs to be frequently moved or rearranged, the use of the mobile caster 603 can avoid the time and cost of transportation and installation. Through the setting of the locking plate 604, the mobile caster 603 usually has a locking function to ensure the stability and safety of the machine tool during operation.

[0026] Working principle:

[0027] When in use, the device is moved into the workshop by moving the casters 603, and the position of the moving casters 603 after moving is locked by the locking plate 604. The support plates 302 on both sides are fixedly connected by the fixing brackets 401 and the hexagonal bolts 402. The CNC machine tool is installed on the inner side of the lifting structure by the plum bolts 501 and the gaskets 502 to form an integral built-in lifting structure. The support plate 302 is fixedly connected to the lifting platform 1 by the fixing base 301, and the mounting plate 203 is moved up and down inside it by the sliding groove 303 and the rectangular groove 304. The positioning plate 305 limits the up and down movement of the mounting plate 203, and the electric telescopic rod 202 is fixedly connected to the lifting platform 1 through the fixed base 201. The electric telescopic rod 202 provides a power source for the up and down movement of the mounting plate 203. The electric telescopic rod 202 generates lower noise during movement, which reduces noise pollution compared to the threaded rod transmission structure. The electric telescopic rod 202 moves more smoothly and can provide more precise height adjustment and positioning. The electric telescopic rod 202 adopts a direct drive method, which reduces the number of transmission components, thereby improving the reliability of the entire lifting structure.

[0028] In summary: the fixed base 201, the electric telescopic rod 202 and the mounting plate 203 contained in the noise reduction mechanism 2 can realize the function of reducing noise, increasing stability, providing an installation platform, and facilitating maintenance and adjustment during the use of the equipment, thereby improving the working environment, performance and operability of the equipment. The electric telescopic rod 202 can replace the traditional threaded rod transmission structure for height adjustment to reduce the noise problem. The fixed base 301, the support plate 302, the slide groove 303, the rectangular groove 304 and the limit plate 305 contained in the sliding mechanism 3 can realize the function of providing support and stability, sliding, limiting the range of motion, etc. during the use of the equipment, and ensure the accuracy, stability and safety of the equipment during the use. The limit plate 305 is used to limit the up and down movement range of the electric telescopic rod 202 to prevent accidents or damage caused by exceeding the set range. By correctly setting and installing the limit plate 305, it can be ensured that the equipment operates within a safe range and provides reliable protection.
