[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A switch chassis: comprising a box body 1, a universal wheel 11 is provided at the bottom of the box body 1, a guide rail 2 is fixedly connected to the surface of the box body 1, a slider 21 is slidably connected to the surface of the guide rail 2, a switch rack 22 is fixedly connected to the surface of the slider 21, a switch is fixedly installed on the surface of the switch rack 22, a support block 23 is fixedly connected to the surface of the box body 1, and a limit rod 24 is rotatably connected to the surface of the support block 23. The switch chassis installs the switch on the switch rack 22, and the switch rack 22 can be slid out of the box body 1, thereby facilitating the installation and maintenance of the switch, avoiding workers from performing installation and maintenance work inside the box body 1, facilitating operation, and improving the work efficiency of workers.

[0024] Furthermore, a cleaning mechanism is provided on the surface of the box body 1, and the cleaning mechanism includes a limiting column 3, which is fixedly connected to the surface of the box body 1, and a dustproof plate 31 is placed on the surface of the box body 1, and spring plates 32 are fixedly connected to both sides of the dustproof plate 31. Positioning holes 33 are opened on the surface of the spring plate 32, and the limiting column 3 is perforated and connected to the positioning holes 33. If the top of the box body 1 is not cleaned for a long time, dust will exist, which will affect the appearance of the box body 1, and even dust will enter the inside of the box body 1 and affect the use of the switch. Since the top of the box body 1 is difficult to disassemble, the cleaning process of the top of the box body 1 is more complicated, and the cleaning is very troublesome and laborious.

[0025] Furthermore, two groups of guide rails 2 are provided, and two groups of sliders 21 are slidably connected to each group of guide rails 2. The exchange rack 22 slides on the surface of the guide rail 2 through the sliders 21. The exchange rack 22 can slide on the guide rail 2 to fall off the box 1, so that the exchange rack 22 becomes a separate individual. At this time, there is more space for installing and maintaining the switches on the exchange rack 22, which is convenient for operation. The exchange rack 22 is supported on the ground by the sliders 21.

[0026] Furthermore, a rectangular groove is opened on the surface of the support block 23, and the limit rod 24 rotates on the rectangular groove of the support block 23. The limit rod 24 can rotate ninety degrees on the surface of the box body 1 through the support block 23. The rotational friction of the limit rod 24 on the support block 23 is relatively large, and only manual operation can change the angle of the limit rod 24 on the box body 1.

[0027] Furthermore, four groups of limit rods 24 are provided, and the limit rods 24 limit the exchange rack 22 on the surface of the box body 1. When the limit rods 24 are parallel to the horizontal plane, the limit rods 24 and the two sides of the exchange rack 22 are on the same horizontal plane. The limit rods 24 limit the exchange rack 22 inside the box body 1, and the exchange rack 22 cannot slide inside the box body 1.

[0028] Furthermore, the diameter of the limit column 3 is the same as the diameter of the positioning hole 33. The limit column 3 limits the position of the spring plate 32 on the limit column 3 through the positioning hole 33. The spring plate 32 changes its shape through elasticity, so that both sets of spring plates 32 can be perforated and connected to the positioning hole 33.

[0029] Furthermore, the dustproof plate 31 and the spring plate 32 are perpendicular to each other, the surface area of ​​the dustproof plate 31 is the same as the surface area of ​​the top of the box body 1, the dustproof plate 31 is just installed on the top of the box body 1, the dustproof plate 31 is fixedly installed on the top of the box body 1 through the spring plate 32, the dustproof plate 31 can be removed from the box body 1 through the spring plate 32, the dustproof plate 31 blocks the dust on the original box body 1, and the dustproof plate 31 can be removed for cleaning.

[0030] Working principle: Rotate the limit rod 24 on the surface of the support block 23 to be perpendicular to the horizontal plane. At this time, the limit rod 24 and the two sides of the exchange rack 22 are not in the same horizontal plane. The limit rod 24 cancels the restriction on the exchange rack 22 inside the box 1. The exchange rack 22 can slide on the guide rail 2 through the slider 21, and the exchange rack 22 can be slid out of the guide rail 2, thereby falling off the inside of the box 1. There will be more space for maintenance and installation of the switch inside the exchange rack 22, and the staff will find it more convenient to operate, thereby improving the staff's work efficiency.

[0031] The dustproof plate 31 blocks the dust on the top of the box body 1. The spring plates 32 are pulled on both sides of the dustproof plate 31 to deform the spring plates 32 and cause the positioning holes 33 on the spring plates 32 to fall off the limiting columns 3 on the box body 1. At this time, the spring plates 32 cancel the restriction on the dustproof plate 31, and the dustproof plate 31 can be directly removed from the box body 1, making it convenient to clean the dust on the dustproof plate 31.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
