[0007] By adopting the above technical solution, the sliding rod is made to slide on the frame through the sliding assembly, thereby driving the mounting plate on the sliding rod to slide in the height direction of the box body, so that the position of the mounting plate can be adjusted without the aid of external tools, thereby improving the convenience of using the switch cabinet.

[0008] Preferably, a limit plate is symmetrically arranged on one side of the sliding assembly close to the frame, and the frame is symmetrically provided with sliding grooves for the limit plate to slide along the height direction.

[0009] By adopting the above technical solution, the limiting plate presses against the frame in the slide groove, so that the sliding assembly is limited on the frame and slides along the height direction on the frame, thereby reducing the situation where the sliding assembly is separated from the frame, thereby improving the stability of the sliding assembly in use.

[0010] Preferably, an insert piece is provided on one side of the sliding rod close to the sliding assembly, and a slot for inserting and installing the insert piece is provided on the sliding assembly, and the slot is perpendicular to the sliding groove.

[0011] By adopting the above technical solution, the insert is pressed against the sliding assembly in the slot, thereby fixing the sliding rod in the sliding assembly. The slot and the slide groove are arranged vertically to reduce the situation where the sliding rod is driven by the gravity of the electronic components installed on the mounting plate and detached from the sliding assembly, thereby improving the stability of the sliding rod installation.

[0012] Preferably, a pressing block is provided on the sliding component, and a penetration hole is opened on the sliding component for the pressing block to pass through the slot, and the pressing block presses against the insert piece in the slot.

[0013] By adopting the above technical solution, when the plug is inserted into the slot, the pressing block passes through the penetration hole into the slot and presses the plug, thereby reducing the situation where the plug falls out of the slot and improving the stability of the plug installation.

[0018] Preferably, a limiting column is arranged on one side of the sliding assembly close to the frame, and a limiting cavity for inserting the limiting column is provided on the frame.

[0019] By adopting the above technical solution, the limiting column presses against the frame in the limiting cavity, thereby fixing the sliding assembly on the frame, reducing the sliding of the sliding assembly on the frame, and further improving the stability of the installation of the sliding assembly.

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a box-type fixed switch cabinet, including a box body 1, a cabinet door 24, an observation window 25, a frame 2, a sliding rod 3, a sliding assembly 4 and a mounting plate 5. The box body 1 is used to accommodate electronic components, and three independent mounting cavities 27 for mounting electronic components are reserved on the box body 1. The cabinet door 24 is hinged on the box body 1, and the cabinet door 24 is used to close the mounting cavity 27. In this embodiment, four cabinet doors 24 are hinged on the box body 1. The observation window 25 is embedded in the cabinet door 24, and the observation window 25 is used to directly observe the reading of the electronic components in the mounting cavity 27 from the outside. The frame 2 is welded to the box body 1, and the frame 2 is located in the mounting cavity 27. The frame 2 is used to support the electronic components in the mounting cavity 27. The sliding rod 3 is symmetrically arranged on the frame 2, and the sliding assembly 4 is symmetrically arranged between the sliding rod 3 and the frame 2 so that the sliding rod 3 slides in the height direction of the frame 2. The mounting plate 5 is welded to the sliding rod 3 to slide synchronously with the sliding rod 3 in the height direction of the frame 2 . The mounting plate 5 is provided with mounting holes 26 for fixing electronic components with bolts, and the mounting holes 26 face the direction of the cabinet door 24 .

[0038] Reference Figure 3 and Figure 4 , combined with Figure 2A limit plate 6 is symmetrically and integrally arranged on one side of the sliding assembly 4 close to the frame 2. The limit plate 6 is arranged in an "L" shape. A sliding groove 7 for the limit plate 6 to slide is symmetrically opened on the frame 2 along the height direction. The limit plate 6 is pressed against the frame 2 in the sliding groove 7, thereby limiting the sliding assembly 4 on the frame 2.

[0039] Reference Figure 3 and Figure 4 A limiting column 15 is provided on one side of the sliding component 4 close to the frame 2, and a limiting cavity 16 for limiting the limiting column 15 is evenly opened on the frame 2 along the height direction. The limiting column 15 is pressed against the frame 2 in the limiting cavity 16, thereby fixing the limiting component on the frame 2.

[0040] Reference Figure 3 and Figure 4 A compression spring 17 is provided on one side of the sliding assembly 4 close to the limiting column 15 to drive the limiting column 15 to press against the frame 2. The sliding assembly 4 is provided with a compression spring groove 18 for installing the compression spring 17. One end of the compression spring 17 presses against the bottom of the compression spring groove 18, and the other end of the compression spring 17 presses against one end of the limiting column 15. The compression spring groove 18 allows the limiting column 15 to slide. When the limiting column 15 is pressed, the limiting column 15 retracts into the compression spring groove 18 to reduce wear. When the limiting column 15 is not pressed, the compression spring 17 drives the limiting column 15 to pop out into the limiting cavity 16.

[0041] Reference Figure 3 and Figure 4 A pressing block 19 for driving the limiting post 15 to retract into the cavity of the compression spring 17 is provided on the side of the sliding assembly 4 close to the limiting post 15, and a penetration groove 20 for the pressing block 19 to penetrate into the compression spring groove 18 is provided on the sliding assembly 4. A guide surface 21 is provided on the side of the pressing block 19 close to the limiting post 15, and the guide surface 21 gradually approaches the compression spring 17 in a direction away from the limiting post 15. An embedding groove 22 for the limiting post 15 to be embedded is provided on the limiting post 15. When the pressing block 19 is pressed, the guiding surface 21 presses against the embedding groove 22, thereby driving the limiting post 15 to retract into the compression spring groove 18. When the compression spring 17 drives the limiting post 15 to pop out into the limiting cavity 16, the embedding groove 22 presses against the guiding surface 21, thereby driving the pressing block 19 to pop out.

[0042] Reference Figure 3 and Figure 4, a limit block 23 is symmetrically and integrally arranged on the circumferential outer surface of the pressing block 19, and the through groove 20 is provided for the limit block 23 to slide. The limit block 23 presses against the sliding assembly 4 in the through groove 20 to reduce the circumferential rotation of the pressing block 19 on the sliding assembly 4. When the compression spring 17 drives the limit column 15 to pop out into the limit cavity 16, the pressing block 19 pops out to the side away from the sliding assembly 4, and the limit block 23 presses against the sliding assembly 4 in the through groove 20 to prevent the pressing block 19 from being separated from the sliding assembly 4. When the limit column 15 pops out into the limit cavity 16, a part of the pressing block 19 is still located in the embedded groove 22 to reduce the situation where the pressing block 19 loses the match with the limit column 15. Both ends of the through groove 20 are connected to the outside world, and the limit block 23 slides from one end of the through groove 20 into the sliding assembly 4 with the pressing block 19 and presses against the sliding assembly 4 at the other end of the through groove 20.

[0043] Reference Figure 4 and Figure 5 , both ends of the sliding rod 3 are integrally provided with inserting pieces 8, and the sliding assembly 4 is provided with a slot 9 for inserting the inserting piece 8, and the slot 9 is perpendicular to the slide groove 7 to reduce the situation that the sliding rod 3 is separated from the sliding assembly 4. A pressing block 10 is provided on the sliding assembly 4, and a penetration hole 11 is provided on the sliding assembly 4 for the pressing block 10 to penetrate into the slot 9, and the pressing block 10 presses against the inserting piece 8 in the slot 9 to reduce the situation that the inserting piece 8 is separated from the sliding assembly 4.

[0044] Reference Figure 4 and Figure 5 A clamping block 12 is integrally provided on the side of the pressure block 10 away from the sliding component 4, and a hole 11 is provided for the clamping block 12 to be embedded and installed. A limiting protrusion 13 is integrally provided on the side of the clamping block 12 close to the sliding component 4, and a limiting groove 14 is provided on the sliding component 4 for the limiting protrusion 13 to be embedded. The limiting protrusion 13 presses against the sliding component 4 in the limiting groove 14 to reduce the situation where the clamping block 12 is separated from the penetration hole 11, thereby reducing the situation where the pressure block 10 is separated from the sliding component 4.

[0045] Working process:

[0046] 1. Press the pressing block 19. At this time, the guide surface 21 and the embedding groove 22 are pressed against each other to make the limit column 15 retract into the cavity of the compression spring 17. The compression spring 17 is deformed by the pressure.

[0047] 2. When the limiting column 15 is completely separated from the limiting cavity 16, the four sliding components 4 are driven to slide synchronously in the height direction of the frame 2 to a suitable height. At this time, the sliding components 4 drive the two sliding rods 3, and the two sliding rods 3 drive the mounting plates 5 thereon to slide in the height direction of the frame 2;

[0048] 3. When the sliding assembly 4 slides to a suitable height, release the pressing block 19. At this time, the compression spring 17 drives the limiting column 15 to pop out into the limiting cavity 16 to fix the sliding assembly 4 on the frame 2, and the compression spring 17 recovers its deformation, and the embedded groove 22 presses against the guide surface 21 to make the pressing block 19 pop out to the side away from the limiting column 15 until the limiting block 23 presses against the sliding assembly 4.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
