Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a control cabinet structure. Background Technology

[0002] A control cabinet (also known as a distribution cabinet or electrical control cabinet) is a housing or enclosure used to install and protect electrical control equipment. It is widely used in various fields such as industry, construction, and transportation. Its main function is to centrally control, protect, and monitor electrical equipment to ensure its normal operation and prevent overload, short circuit, and other faults.

[0003] A search of Chinese patent document CN218732639U reveals a high- and low-voltage control cabinet structure, including a cabinet body and a base. Two opposing vertical side panels of the cabinet body are located on opposite sides of the base. The base is a shell structure and includes a drive mechanism for moving one of the vertical side panels of the cabinet body along the base. The front and rear openings of the cabinet body are hinged to a front door and a rear door, both located on the upper part of the base. The cabinet body, front door, rear door, and the upper surface of the base form a control cabinet chamber. A support frame for installing electrical components is located on the upper part of the base within the control cabinet chamber. This invention allows electrical components mounted on the support frame to protrude from the cabinet body, providing operators with a larger maintenance and operation space, facilitating maintenance and operation, and solving the problems of limited space and inconvenience in traditional cabinet operations. It has excellent practical effects.

[0004] The control cabinet dissipates heat through ventilation grilles, which can effectively reduce the internal temperature. However, because the ventilation grilles lack a dustproof structure on the outside, dust, dirt, and particles from the outside can easily enter the cabinet. Over time, this dust will accumulate on electrical components, wiring, and circuit boards, thus affecting the heat dissipation effect, increasing the risk of equipment failure, and reducing the service life of the control cabinet. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a control cabinet structure, which aims to improve the problem in the prior art where the lack of a dustproof structure on the outside of the ventilation grille allows external dust, dirt and particulate matter to easily enter the cabinet, and over time, this dust will accumulate on electrical components, wiring and circuit boards.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A control cabinet structure includes a cabinet body, shock absorbers are installed on all four sides of the lower part of the cabinet body, a cabinet door is installed on the outside of the cabinet body, a ventilation hole is opened on the right side of the outside of the cabinet body, a dustproof component is installed outside the ventilation hole, and wiring holes are opened on both sides of the lower part of the cabinet body, and a sealing component is installed outside the wiring holes.

[0008] The dustproof assembly includes a dust cover disposed outside the ventilation hole. A slider is slidably connected inside the dust cover. An insert is fixedly connected to the left side of the slider. A spring is fixedly connected to the right side of the insert. A crossbar is fixedly connected to the front side of the slider.

[0009] Furthermore, the sealing assembly includes a mounting block, which is fixedly connected to the outside of the wire hole. A bidirectional lead screw is rotatably connected inside the mounting block. A turntable is fixedly connected to the left side of the bidirectional lead screw. Moving blocks are threadedly connected to both sides of the bidirectional lead screw. Limit blocks are fixedly connected to the lower part of each of the two moving blocks. Connecting rods are fixedly connected to the outside of each of the two moving blocks. Arc-shaped blocks are fixedly connected to the outside of each of the two connecting rods.

[0010] Furthermore, a groove is provided on the right side of the exterior of the cabinet, and the dust cover is inserted into the groove.

[0011] Furthermore, a slot is provided inside the cabinet, and the plug is inserted into the slot.

[0012] Furthermore, the dust cover has a through hole on its exterior, and the crossbar is slidably connected inside the through hole.

[0013] Furthermore, limit grooves are provided on both sides of the lower part of the mounting block, and the two limit blocks are slidably connected inside the two limit grooves.

[0014] Furthermore, both of the arc-shaped blocks are provided with sealing gaskets on their exteriors, and both sealing gaskets are made of rubber.

[0015] Furthermore, an indicator light is installed on the outside of the cabinet door, an ammeter and voltmeter are installed below the indicator light, a touch screen is installed on the outside of the ammeter and voltmeter, and a switch button is installed below the ammeter and voltmeter.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, when installing the dust cover, the slider is first moved by moving the horizontal bar. The slider causes the insert to move synchronously, squeezing the right spring and causing it to deform. When the insert enters the dust cover, it aligns with the groove and is locked inside. After releasing the horizontal bar, the spring's reaction force pushes the insert into the slot, thus fixing the dust cover. The dust cover effectively prevents dust, dirt, and particles from entering the cabinet, protecting electrical components and extending the service life of the control cabinet.

[0018] In this invention, when installing cables, the cables are inserted through the cable hole, and the turntable is rotated to drive the bidirectional lead screw to rotate. The moving block moves relative to the moving block, which in turn moves the connecting rod, the arc block and the sealing gasket. Finally, the cable is fixed and the cable hole is sealed. This design prevents the cable from being damaged by vibration or friction and prevents moisture, humidity and dust from entering the cabinet, thus extending the service life of the control cabinet.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-6 This utility model provides an embodiment of a control cabinet structure, including a cabinet body 1. Shock absorbers 2 are installed around the lower perimeter of the cabinet body 1 to reduce the impact of external vibrations on the cabinet body 1 and internal equipment. A cabinet door 3 is installed on the exterior of the cabinet body 1. A ventilation hole 8 is provided on the right side of the exterior of the cabinet body 1 to dissipate heat from the interior of the cabinet body 1. A dustproof component is installed outside the ventilation hole 8 to prevent dust from entering the interior of the cabinet body 1. Cable threading holes 26 are provided on both sides of the lower part of the cabinet body 1 to facilitate the threading of cables. The cable is operated by a sealing component on the outside of the cable hole 26. The sealing component facilitates the fixing of the cable and the sealing of the cable hole 26. An indicator light 4 is installed on the outside of the cabinet door 3 to display the real-time operating status of the control cabinet or the equipment inside. An ammeter and voltmeter 6 is installed below the indicator light 4 to display the working status of the electrical equipment inside the cabinet 1. A touch screen 5 is installed on the outside of the ammeter and voltmeter 6 to provide a more intuitive and intelligent control and monitoring interface. A switch button 7 is installed below the ammeter and voltmeter 6 for manual control of the electrical equipment in the control cabinet.

[0030] The dustproof assembly includes a dust cover 10, which is located outside the ventilation hole 8. A slider 11 is slidably connected inside the dust cover 10. An insert 12 is fixedly connected to the left side of the slider 11, and a spring 14 is fixedly connected to the right side of the insert 12. A crossbar 13 is fixedly connected to the front side of the slider 11. The crossbar 13 facilitates the use of the operator. A groove 9 is provided on the right side of the cabinet body 1, and the dust cover 10 is inserted into the groove 9. A slot 15 is provided inside the cabinet body 1, and the insert 12 is inserted into the slot 15, which improves the stability of the dust cover 10 installation. A through hole 16 is provided on the outside of the dust cover 10, and the crossbar 13 is slidably connected inside the through hole 16, which facilitates the movement of the crossbar 13.

[0031] Specifically, when installing the dust cover 10, the operator first moves the bottom-fixed slider 11 by moving the crossbar 13. Since the slider 11 is connected to the outer left-fixed insert 12, the movement of the slider 11 will cause the insert 12 to move synchronously. At this time, the slider 11 will apply pressure to the outer right-fixed spring 14 during the movement, causing the spring 14 to deform under force and generate a certain compression. The spring 14 provides sufficient reaction force to ensure the stability and reliability of the installation process. As the slider 11 continues to move, the insert 12 eventually enters the dust cover. Inside the dust cover 10, align the dust cover 10 with the groove 9 and insert the dust cover 10 into the groove 9. Then, the operator releases the crossbar 13. Due to the reaction force of the spring 14, the insert block 12 is pushed into the slot 15 by the spring 14, thus completing the installation of the dust cover 10. With this design, the dust cover 10 can completely cover the outside of the ventilation hole 8, preventing external dust, dirt, particles and other possible pollutants from entering the cabinet 1, preventing pollutants from damaging the equipment inside the control cabinet, thereby improving the service life of the control cabinet.

[0032] Reference Figures 3-7 The sealing assembly includes a mounting block 17, which is fixedly connected to the outside of the cable hole 26. A bidirectional lead screw 18 is rotatably connected inside the mounting block 17. A turntable 19 is fixedly connected to the left side of the bidirectional lead screw 18. The turntable 19 facilitates the operation of the operator. Moving blocks 20 are threadedly connected to both sides of the bidirectional lead screw 18. Limit blocks 21 are fixedly connected to the lower part of each moving block 20. Connecting rods 22 are fixedly connected to the outside of each moving block 20. Arc blocks 23 are fixedly connected to the outside of each connecting rod 22. Arc blocks 23 facilitate the fixing of the cable. Limit grooves 25 are opened on both sides of the lower part of the mounting block 17. The two limit blocks 21 are slidably connected inside the two limit grooves 25. The limit grooves 25 facilitate the movement of the limit blocks 21. Sealing gaskets 24 are provided on the outside of each arc block 23. The two sealing gaskets 24 are made of rubber, which has good elasticity and sealing performance, and can effectively fill gaps to ensure that no leakage occurs when the cable passes through.

[0033] Specifically, during cable installation, the cable is first threaded through the through-hole 26. Next, the operator rotates the turntable 19, causing the bidirectional lead screw 18 to rotate inside the mounting block 17. When the bidirectional lead screw 18 starts to rotate, it interacts with the movable blocks 20 threaded to both sides, causing the two movable blocks 20 to move relative to each other. The movement of the movable blocks 20 causes the two connecting rods 22 fixed to them to move relative to each other. As the connecting rods 22 move relative to each other, they will cause the two externally fixed arc blocks 23 to move relative to each other. The design of the arc blocks 23 allows them to firmly clamp the cable passing through the through-hole 26. The relative movement of the arc blocks 23 will further push the two externally fixed sealing gaskets 24 to move relative to each other. When the sealing gaskets 24 move relative to each other, they tightly wrap around the through-hole 26 and form a seal between them and the cable, thereby ensuring that no gaps allow external moisture, dust, or contaminants to enter the cabinet 1, further extending the life of the control cabinet.

[0034] Working principle: When installing the dust cover 10, firstly, the sliding block 11 fixed at the bottom is moved by the moving crossbar 13. The sliding block 11 moves the outer left fixed plug 12. At the same time, when the sliding block 11 moves, it squeezes the outer right fixed spring 14, causing the spring 14 to deform under force. Then, when the plug 12 enters the interior of the dust cover 10, the dust cover 10 is aligned with the groove 9. Then, the dust cover 10 is inserted into the interior of the groove 9. Then, the crossbar 13 is released, and under the reaction force of the spring 14, the plug 12 is inserted into the slot 15. This realizes the installation of the dust cover 10 outside the ventilation hole 8. The dust cover 10 can effectively prevent external dust, dirt and particles from entering the cabinet 1 and prevent them from accumulating on electrical components, lines and circuit boards, thereby improving the service life of the control cabinet.

[0035] When installing the cable, the cable is inserted through the through hole 26. Then, the turntable 19 is rotated, causing the bidirectional lead screw 18 to rotate inside the mounting block 17. As the bidirectional lead screw 18 rotates, the moving blocks 20 connected to the external threads on both sides move relative to each other. The relative movement of the two moving blocks 20 causes the two externally fixed connecting rods 22 to move relative to each other. As the two connecting rods 22 move relative to each other, the two externally fixed arc blocks 23 move relative to each other. The relative movement of the two arc blocks 23 causes the two externally fixed sealing gaskets 24 to move relative to each other. The cable is fixed by the relative movement of the two sealing gaskets 24, thus completing the fixing of the cable and sealing of the through hole 26. This facilitates the fixing of the cable and the sealing of the through hole 26. Fixing the cable helps prevent the cable from breaking or wearing due to external vibration or friction. Sealing the through hole 26 prevents moisture, humidity, and dust from entering the interior of the cabinet 1, further extending the life of the control cabinet.
