Description

Technical Field

[0001] This utility model relates to the field of PLC control box technology, specifically a PLC control box. Background Technology

[0002] PLC control boxes are widely used devices in electrical control systems, especially in industrial automation control, power control, and metallurgy. Because of their overload, circuit break, and phase loss protection functions, PLC control has become the core of modern industrial control.

[0003] A search revealed that the multi-protection PLC control box with patent publication number CN218275730U proposed that "by installing a fireproof rock wool layer inside the box, the fire resistance of the box to external fires can be improved. When a fire occurs inside the box, the temperature sensor will sense that the temperature inside the box is rising rapidly. When the temperature exceeds the set value of the temperature sensor, the temperature sensor will transmit a signal to the controller inside the box. The controller will then open the electric nozzle, allowing the dry powder in the dry powder tank to be sprayed out, thereby achieving the fire extinguishing effect."

[0004] However, the above solution still has some shortcomings in actual use. Since the PLC control box needs to be maintained regularly for its internal components during operation, the staff needs to crawl inside the PLC control box to maintain the components. However, due to the small internal space of the PLC control box, the staff's range of movement is limited, making daily maintenance or repair work very difficult, increasing the workload of the staff, and making the whole repair process time-consuming and laborious, which is not conducive to the repair work of maintenance personnel.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model discloses a PLC control box, including a box body 1. The box body 1 has an installation groove 3 inside. The inner wall of the installation groove 3 is provided with a pushing device 2. A baffle 4 is fixedly connected to the opening of the installation groove 3. The top of the baffle 4 overlaps with the movable end of the pushing device 2.

[0022] The pushing device 2 includes a drive box 201, and a displacement platform 202 is provided at the top of the drive box 201. A component mounting bracket 203 and a side plate 204 are fixedly installed at the top of the displacement platform 202.

[0023] The inner wall of the drive box 201 is rotatably connected to a drive shaft 207 via a built-in motor. A sliding ring 208 is sleeved on the surface of the drive shaft 207, and an arc groove is formed on the surface of the drive shaft 207. A plug rod is fixedly installed on the inner wall of the sliding ring 208, and the plug rod is movably inserted into the inner wall of the arc groove. A hinge rod 210 is rotatably connected to the outer side of the sliding ring 208 via a connecting seat 209. A push plate 211 is hinged to the other end of the hinge rod 210. A lifting rod 212 is fixedly installed on the top end of the push plate 211, and the bottom end of the lifting rod 212 is fixedly connected to the bottom end of the displacement platform 202.

[0024] By setting up the pushing device 2, the drive shaft 207 inside the drive box 201 can drive the lifting rod 212 to slide horizontally through the hinge rod 210, so that the displacement platform 202 can move the component mounting bracket 203 and the side plate 204 out of the box 1. This exposes the components on the component mounting bracket 203 to the workers, so that the workers do not need to crawl into the box 1 to inspect the components. This makes the inspection of the components simpler and more convenient, reduces the difficulty of inspection and the workload, thereby reducing the labor intensity of maintenance personnel and achieving the advantage of convenient maintenance.

[0025] Specifically, the bottom end of the displacement platform 202 is provided with a notch, and the inner wall of the notch is rotatably connected to a hinged roller 205 by a damping spring 206. The bottom end of the hinged roller 205 overlaps with the top end of the baffle 4.

[0026] In this embodiment, during the movement of the displacement platform 202, the displacement platform 202 will slide relative to the baffle 4. When the baffle 4 no longer blocks the notch at the bottom of the displacement platform 202, the automatic rebound of the damping spring 206 will cause the articulated roller 205 to deflect at an angle, so that the articulated roller 205 will eventually contact the ground and be perpendicular to the ground, so that the articulated roller 205 can move with the displacement platform 202, and the articulated roller 205 can slide to lift the displacement platform 202.

[0027] Specifically, the side end of the housing 1 is provided with an extension opening, and the overall dimensions of the displacement platform 202 and the side plate 204 are adapted to the size of the extension opening.

[0028] In this embodiment, the displacement platform 202 will repeatedly pass through the extension opening during its movement. By matching the overall specifications of the displacement platform 202 and the side plate 204 with the size of the extension opening, the displacement platform 202 and the side plate 204 can completely close the extension opening, thereby preventing debris from entering the interior of the box 1.

[0029] Specifically, a slider is fixedly installed on the side end of the push plate 211, and the slider is slidably connected to the inner wall of the drive box 201.

[0030] In this embodiment, the slider follows the push plate 211 and slides along the inner wall of the drive box 201, making the movement of the push plate 211 more stable.

[0031] When it is necessary to inspect and maintain the components on the component mounting bracket 203 during use, the push device 2 is activated, which causes the built-in motor inside the drive box 201 to drive the drive shaft 207 to rotate. Since the surface of the drive shaft 207 has an arc groove with the ends connected, and the inner cavity of the sliding ring 208 is fixedly connected to a rod extending into the arc groove, the rod can drive the sliding ring 208 to change its relative position on the surface of the drive shaft 207 while the drive shaft 207 drives the arc groove to rotate, thus causing the sliding ring 208 to move in the axial direction on the surface of the drive shaft 207.

[0032] The sliding ring 208 causes the hinge rod 210 to deflect at an angle, which in turn causes the hinge rod 210 to push the push plate 211 to slide on the inner wall of the drive box 201. This causes the push plate 211 to drive the displacement platform 202 to move synchronously through the lifting rod 212, so that the displacement platform 202 gradually moves from above the drive box 201 to the outside of the housing 1, exposing the components on the component mounting bracket 203 to the workers.

[0033] During the movement of the displacement platform 202, the displacement platform 202 will slide relative to the baffle 4. When the baffle 4 is no longer blocking the notch at the bottom of the displacement platform 202, the automatic rebound of the damping spring 206 will cause the articulated roller 205 to deflect at an angle, so that the articulated roller 205 will eventually contact the ground and be perpendicular to the ground, so that the articulated roller 205 can move with the displacement platform 202, and the articulated roller 205 can slide to lift the displacement platform 202.

[0034] In summary, this PLC control box, by setting up a pushing device 2, utilizes the drive shaft 207 inside the drive box 201 to drive the lifting rod 212 to slide horizontally via the hinge rod 210, causing the displacement platform 202 to move horizontally. This allows the displacement platform 202 to move the component mounting bracket 203 and the side plate 204 out of the box 1, exposing the components on the component mounting bracket 203 to the workers. This allows workers to inspect the components without having to crawl inside the box 1, making component inspection simpler and more convenient, reducing the difficulty and workload of inspection, and thus reducing the labor intensity of maintenance personnel, achieving the advantage of convenient maintenance.

[0035] 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.
