[0023] Example

[0024] like Figure 1-5As shown, an embodiment of the utility model proposes an incoming line protection structure of an electrical control cabinet. The incoming line protection structure of the electrical control cabinet designed in this scheme can realize the adjustment of incoming lines at different heights through design, and can improve the protection of the incoming line end of the electrical control cabinet. It includes a telescopic connecting plate 2 and a wire-passing component 3. The telescopic connecting plate 2 is symmetrically connected to the cabinet body 1. The wire-passing component 3 is connected between the two telescopic connecting plates 2. The wire-passing component 3 is connected to the cabinet body 1 in a coordinated manner. A blocking piece 4 is slidably connected to the wire-passing component 3. The blocking piece 4 is symmetrically provided with limiting pieces 5. The two limiting pieces 5 are connected to the wire-passing component 3 in a coordinated manner. The telescopic connecting plate 2 is connected on both sides of the wire-passing component 3. The telescopic connecting plate 2 is composed of a plurality of closing plates that cooperate with each other to slide. The connection composition is that a plurality of closing plates can be slidably stacked, and the height of the wire frame 301 at the wire entry hole 101 can be adjusted to control the entry of wires at different heights. By turning the knob 307 to rotate the screw rod 306, the threaded seat 305 threadedly connected to the screw rod 306 can slide, so that the height of the wire frame 301 at the wire entry hole 101 can be adjusted and controlled. When the wire frame 301 is adjusted, the telescopic connecting plate 2 can be blocked at the wire entry holes 101 on both sides of the wire frame 301 to avoid gaps in the wire entry holes 101 after the height of the wire frame 301 is adjusted, thereby improving the closing effect. By adjusting the height of the wire frame 301, it is possible to adapt to the use of different wire entry heights when different electrical equipment is installed inside the cabinet 1, which meets the requirements. Sufficient diversified use effect, by passing the connecting wire through the wire frame 301, the connecting wire will be in the distance between the rubber seat 302 and the contact head 402, at this time, by pressing down the blocking plate 401, the blocking plate 401 can be slid down in the plug-in slot 303, the blocking plate 401 slides symmetrically with the limiting member 5, the tooth head 502 arranged at one end of the L-shaped rod 501 is matched and connected with the tooth seat 304, when the blocking plate 401 is pressed down, the tooth head 502 and the tooth seat 304 are matched and meshed, due to the spring 503 arranged on one side of the L-shaped rod 501, when the blocking plate 401 is pressed down, the L-shaped rod 501 can be kept in the blocking plate 401 with a shrinkage and rebound effect, which satisfies the matching and engaging use of the tooth head 502 and the tooth seat 304. Through design, The blocking plate 401 can be pressed down and slid in the plug slot 303. When it is adjusted upward, the two L-shaped rods 501 need to be pinched to make the tooth head 502 disconnect from the tooth seat 304. At this time, the blocking plate 401 can be adjusted upward. When the blocking plate 401 is pressed down, the contact head 402 will contact the connecting line. Since the contact head 402 has a rubber sleeve combination with a non-Newtonian fluid, when the blocking plate 401 is pressed down, due to the characteristics of the non-Newtonian fluid, the contact head 402 can be tightly filled in the spacing between the connecting lines, thereby cooperating with the rubber seat 302 to achieve sealing of the incoming line end, preventing external insects and animals from entering the electrical control cabinet through the gap of the incoming line segment and damaging the internal connecting lines, thereby improving the protection effect.The contents not described in detail in this specification belong to the prior art known to professionals in this field.
