DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] The utility model discloses a chassis for a power cabinet that is easy to install. The chassis is mainly used to fix the chassis on the cabinet by screws, which is inconvenient to disassemble and install the chassis. The chassis cannot be disassembled in the absence of a screwdriver, which makes it inconvenient to replace parts, and the work efficiency is low when disassembling and assembling the chassis.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A chassis for a power cabinet that is easy to install includes a power cabinet body 1, a box door 2 is rotatably connected to the front end of the power cabinet body 1, and a chassis 10 is slidably connected inside the power cabinet body 1. It also includes: a fixing component: a limit strip 11 is fixedly installed at the middle end of the power cabinet body 1, and a slide groove 12 is opened at the left and right ends of the chassis 10. A limit block 13 is fixedly installed at the rear end of the slide groove 12, and a clamping strip 15 is fixedly installed at the upper and lower ends of the slide groove 12. The left and right ends of the power cabinet body 1 are located at the front end of the limit strip 11 and are slidably connected with a clamping piece 14. Fixed blocks 16 are fixedly installed on the left and right sides of the front end of the chassis 10, and a flexible hook 17 is welded and connected to the rear end of the fixed block 16; a limiting component: the limiting component is arranged inside the limiting strip 11, and the limiting component is used to limit the sliding of the chassis 10.

[0022] In this solution, when the chassis 10 is installed inside the power cabinet body 1, the slide groove 12 on the chassis 10 is docked with the limit strip 11, and the chassis 10 is slid into the power cabinet body 1. When the chassis 10 slides, the card strip 15 will also slide on the limit strip 11 to prevent the chassis 10 from shifting position, while improving the stability of the subsequent sliding of the chassis 10. After the chassis 10 is completely slid into the power cabinet body 1, the sliding card connector 14 is made to slide into the fixing block 16, and the flexible hook 17 in the fixing block 16 will fix the card connector 14, thereby The chassis 10 is limited to improve the stability of the chassis 10 during installation. When the clamping piece 14 is disengaged from the clamping connection with the flexible hook 17 and slides to the front end of the limiting component, the clamping piece 14 releases the sliding limit of the chassis 10, which is convenient for maintenance and inspection of the chassis 10. At the same time, the clamping piece 14 will cooperate with the limiting component, and the limiting block 13 will be blocked by the limiting component to limit the maximum sliding distance of the chassis 10, thereby preventing the chassis 10 from sliding out and being damaged due to operator errors. The fixed component has a simple structure, which is convenient for disassembly and assembly of the power cabinet body 1, and is conducive to improving work efficiency.

[0023] Reference Figure 1 and Figure 2 In a preferred embodiment, a fixing frame 5 is fixedly installed in the middle of the rear end of the power cabinet body 1, a protective cover 3 is fixedly installed on the left side of the rear end of the power cabinet body 1, and a roller 4 is rotatably connected inside the protective cover 3. A clamping block 6 is fixedly installed on the right side of the rear end of the power cabinet body 1, and a winding drum 7 is rotatably connected to the rear end of the clamping block 6. A knob 9 is embedded at the lower end of the winding drum 7, and a filter screen 8 is arranged at the rear end of the fixing frame 5. The left side of the filter screen 8 is bonded to the outer side of the roller 4, and the right side of the filter screen 8 is bonded to the outer side of the winding drum 7.

[0024] Specifically, when too much dust accumulates on the filter screen 8 at the rear end of the fixed frame 5 and affects the heat dissipation of the power cabinet body 1, the knob 9 is turned to drive the embedded winding drum 7 to rotate, and the dirty section of the filter screen 8 is rolled up onto the winding drum 7. The drum 4 will also rotate to transport the clean section of the filter screen 8 to the rear end of the fixed frame 5 to prevent the dust from falling on the filter screen 8 and seriously affecting the heat dissipation effect of the power cabinet body 1. When all the filter screens 8 on the drum 4 have been transported and the winding drum 7 has rolled up all the dirty filter screens 8, the winding drum 7 is removed from the clamping block 6 to clean the filter screen 8, which is conducive to improving work efficiency.

[0025] Reference Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the limiting component includes an empty slot 18 opened at the front end of the limiting strip 11, a docking block 19 is slidably connected to the front end of the empty slot 18, a clamping block 20 is slidably connected to the side of the empty slot 18 close to the central axis, a push block 21 is fixedly installed at the front end of the clamping block 20, and a spring 22 is arranged between the clamping block 20 and the empty slot 18.

[0026] Specifically, when the chassis 10 needs to be slid, the card connector 14 is slid to the left to release the lock on the chassis 10. The card connector 14 will force the docking block 19 to slide to the rear end. The sliding of the docking block 19 to the rear end will push the push block 21 to slide to the side close to the central axis, so that the card block 20 presses the spring 22 to slide out of the empty groove 18, limiting the maximum sliding distance of the chassis 10. At the same time, when the chassis 10 needs to be disassembled, it is only necessary to slide the card connector 14 completely out of the upper end of the docking block 19. The spring 22 resets and drives the card block 20 to reset, thereby releasing the restriction on the limit strip 11 and allowing the chassis 10 to slide out freely.

[0027] Working principle: During installation, the slide groove 12 on the chassis 10 is connected with the limit strip 11, and the chassis 10 is slid into the power cabinet body 1. When the chassis 10 slides, the card strip 15 will also slide on the limit strip 11 to prevent the chassis 10 from shifting position and improve the stability of the subsequent sliding of the chassis 10. After the chassis 10 is completely slid into the power cabinet body 1, the sliding card connector 14 is made to slide into the fixed block 16, and the flexible hook 17 in the fixed block 16 will lock the card connector. 14 is fixed, thereby limiting the chassis 10 and improving the stability of the chassis 10 during installation. When the clamping piece 14 is disengaged from the clamping connection with the flexible hook 17 and slides to the front end of the limiting assembly, the clamping piece 14 releases the sliding limit of the chassis 10, which is convenient for maintenance and inspection of the chassis 10. At the same time, the clamping piece 14 will cooperate with the limiting assembly, and the limiting block 13 will be blocked by the limiting assembly to limit the maximum sliding distance of the chassis 10, thereby preventing the chassis 10 from sliding out and being damaged due to operator errors.

[0028] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
