Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically a pull-out universal electrical control box. Background Technology

[0002] An electrical control box is an enclosure that integrates centralized control, protection, and measurement of electrical equipment. It is usually made of materials such as steel plate, aluminum alloy, and stainless steel, and has functions such as protection, isolation, and heat dissipation. Electrical control boxes are widely used in fields such as power, energy, transportation, chemical industry, metallurgy, and construction for control, measurement, signaling, protection, and regulation of equipment.

[0003] The patent application "202320787098.4" discloses a "pull-out electrical control box mechanism," which "includes a cabinet and an electrical control box. The electrical control box is located inside the cabinet cavity, and two symmetrical slide rails are provided at the bottom of the cabinet. The electrical control box is located above the slide rails, and a push-pull handle is fixedly installed on one side wall of the electrical control box. This utility model, by providing a sliding mechanism at the bottom of the electrical control box, allows the first universal wheel to contact the ground during the removal of the electrical control box. When the electrical control box is pulled further, the first slider changes position with the second slider via a telescopic rod, thereby driving the first and second universal wheels to move. When the first and second sliders move to a critical point, they are supported by a supporting force, thus preventing mechanical movement and allowing the universal wheels to move on the ground. This ensures that the bottom of the electrical control box does not contact the ground, thus preventing wear. This design is suitable for widespread promotion and use."

[0004] However, the above method still has the following drawbacks: the sliding mechanism can make the first caster contact the ground during the process of moving the electrical control box out, but after the electrical control box is pushed out of the cabinet, it occupies a lot of external space and requires the electrical control box door to be opened, which is not convenient for the installation and disassembly of the specified components. The cabinet setting will affect the heat dissipation of the electrical control box and easily lead to heat accumulation inside the electrical cabinet. Utility Model Content

A limiting block 705 is fixedly provided in the middle of one side of the slider 704. Limiting grooves 8 that engage with the limiting blocks 705 are provided on the inner walls of both sides of the housing 1. The bidirectional lead screw 6 is rotated by the knob 9, and the bidirectional lead screw 6 is rotated. The lead screw 6 can convert the rotational motion into the linear motion of the slider 704 through the threaded hole, so that the limiting block 705 can be pushed into the limiting groove 8 of the housing 1, thereby quickly fixing the handle 5. The surface of the horizontal plate 702 is slidably connected to the guide plate 703, and the guide plate 703 is fixedly connected to the inside of the handle 5. The bidirectional lead screw 6 is rotatably connected to the guide plate 703 through the bearing, and the slider 704 is slidably connected to the inside of the handle 5. The guide plate 703 can support the bidirectional lead screw 6 and ensure the horizontal movement of the horizontal plate 702.

[0029] In this embodiment, preferably, the dustproof component 16 includes a float plate 1601, which is located at the top of the air duct 14. The surface of the float plate 1601 is provided with several sliding holes, and a guide post 1602 is slidably connected inside the sliding holes.

A pull rod 1806 is fixedly provided in the middle of the sliding plate 1805. The pull rod 1806 is slidably connected to the middle of the top of the limiting sleeve 1804. A spring 1807 is sleeved on the surface of the pull rod 1806, located between the sliding plate 1805 and the limiting sleeve 1804. A pull button 1808 is fixedly provided at the top of the pull rod 1806, located at the top of the limiting sleeve 1804. The bottom of the housing 1... The inner wall of the air inlet 17 is provided with a groove for engaging with the pull rod 1806. A baffle 21 is fixedly provided on one side of the top of the air inlet 17 to block the plate 1801. Several wire grooves 22 corresponding to the positions of the groove 1802 are provided on one side of the baffle 21. The air inlet 17 can ensure air circulation and facilitate the threading of wires. Pulling the pull button 1808 causes the slide plate 1805 to compress the spring 1807, which can drive the pull rod 1806 to retract, making it easy to engage the plate 1801 with the card seat 23. By releasing the pull button 1808, the spring 1807 can push the bottom end of the pull rod 1806 into the groove, which can prevent the plate 1801 from shifting. The groove 1802 of the plate 1801 and the wire grooves 22 of the baffle 21 can be used to install wires. The dustproof net 1803 on the surface of the plate 1801 can prevent dust from entering the interior of the box 1 through the air inlet 17.

[0031] In this embodiment, preferably, the surface of the shelf 2 is provided with ventilation openings 3 and mounting holes 4. The ventilation openings 3 can ensure the ventilation capacity of the shelf 2, and the mounting holes 4 can be used to fix and install components. Both sides of the shelf 2 are slidably connected with rails 12, and the rails 12 are fixedly connected to the inner wall of the box 1. The rails 12 can support and guide the shelf 2. The four corners of the bottom of the box 1 are fixedly provided with support legs 20, and the bottom of the support legs 20 is fixedly provided with anti-slip pads. The surface of the box 1 is hinged with a door 19.

[0032] In this embodiment, preferably, an inspection port is provided in the middle of one side of the handle 5, and a cover plate 10 is fixedly connected to one side of the inspection port by screws. By opening the cover plate 10, the inside of the handle 5 can be inspected through the inspection port. An operating port 11 is provided in the middle of the cover plate 10 and the middle of the other side of the handle 5. The knob 9 is located inside the operating port 11. The operating port 11 can ensure the installation space of the knob 9 and prevent the knob 9 from contacting the handle 5 and the cover plate 10.

[0033] In use, the staff fixes the components on the shelf 2 through the mounting holes 4. Different specifications of components can be installed by relying on the spacing between the shelves 2. Then, the wires are passed through the air inlet 17 to connect the components. After that, the shelf 2 is pushed into the box 1. Then, the double-acting screw 6 is rotated by the knob 9. The double-acting screw 6 converts the rotational motion into the linear motion of the slider 704 through the threaded hole, which can push the limiting block 705 into the limiting groove 8 of the box 1, thereby quickly fixing the handle 5 and preventing the shelf 2 from sliding. It is safe and reliable.

[0034] After the shelf 2 is fixed, the worker pulls the pull button 1808 of the dustproof component 2 18, causing the slide plate 1805 to compress the spring 1807, which in turn causes the pull rod 1806 to retract. Then, the clamping plate 1801 is engaged with the clamping seat 23. Then, the pull button 1808 is released, and the spring 1807 can push the bottom end of the pull rod 1806 into the rod groove, which can prevent the clamping plate 1801 from shifting. The groove 1802 of the clamping plate 1801 and the wire groove 22 of the baffle 21 can be used to install wires. The dustproof net 1803 can prevent dust from entering the interior of the box 1 through the air inlet 17. Finally, the box door 19 is closed.

[0035] When heat dissipation is required inside the housing 1, the exhaust fan 15 is used to dissipate heat inside the housing 1. The air inlet 17 and the exhaust outlet 13 can ensure air circulation and prevent heat accumulation inside the housing 1. During the heat dissipation process, the airflow can blow the float plate 1601 up to ensure heat dissipation. The guide column 1602 can guide the float plate 1601 to ensure the vertical movement of the float plate 1601 and prevent it from tilting. After the exhaust fan 15 stops working, the float plate 1601 can fall back down by its own weight, which can block the top of the air duct 14 and prevent dust from entering the interior of the housing 1 through the exhaust outlet 13.

[0036] When components need to be disassembled, the staff opens the door 19, rotates the double-acting screw 6 in the opposite direction using the knob 9, causes the limit block 705 to retract, and removes it from the limit groove 8. Then, the shelf 2 can be pulled out from inside the box 1 using the pull handle 5, which allows the disassembly of the specified components.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
