[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-5As shown, a high and low voltage switch cabinet cabinet sealing structure proposed in an embodiment of the utility model includes a high and low voltage switch cabinet body 1, a connection frame 2 and a rubber sealing frame 3. The high and low voltage switch cabinet cabinet sealing structure designed in this scheme can improve the sealing effect of the high and low voltage switch cabinet, and can be adjusted when the sealing effect is not good, so that the seal is tight and meets the use requirements. The high and low voltage switch cabinet body 1 is fixedly connected with the connection frame 2, and the rubber sealing frame 3 is slidably inserted on the connection frame 2. A plurality of adjusting pins 4 are rotatably connected to the rubber sealing frame 3. The adjusting pins 4 are connected to the connection frame 2 in a coordinated manner. The high and low voltage switch cabinet body 1 is fixedly connected with a lead sealing sleeve 5 The rubber sealing frame 3 is tightly slidably inserted in the connecting frame 2, and when the cabinet door 101 is closed on the high and low voltage switch cabinet body 1, the rubber sealing frame 3 can tightly contact the cabinet door 101 to achieve the sealing of the gap between the high and low voltage switch cabinet body 1 and the cabinet door 101. The line introduced into the high and low voltage switch cabinet body 1 is introduced from the lead hole 102. Through the lead sealing sleeve 5 provided at the lead hole 102, the line can be inserted from the fixed plate 501 and led out from the rubber sleeve 502. Through the elastic design of the rubber sleeve 502, the lines with different wire thicknesses can be tightly wrapped, thereby improving the lead wire. The sealing at the hole 102 meets the use of the line introduction and improves the sealing effect of the high and low voltage switch cabinet body 1. After the rubber sealing frame 3 is squeezed for a long time, its rebound and reset effect will become worse, resulting in the inability to tightly fill the gap between the high and low voltage switch cabinet body 1 and the cabinet door 101, affecting the sealing effect. At this time, by rotating the adjusting pin 4, the rubber sealing frame 3 can be slidably adjusted inside the plug-in groove 201 to control the combined thickness of the connecting frame 2 and the rubber sealing frame 3 to meet the filling of different gaps. The rotating column 402 is rotatably connected to the rotating hole 301. When the pin head 401 is rotated, the threaded sleeve 403 will be aligned with the threaded column 20 2 The thread is rotated, so that the combined height of the threaded sleeve 403 and the threaded column 202 can be controlled, so as to meet the sliding adjustment of the rubber sealing frame 3 inside the plug-in slot 201. Since the two sides of the rubber sealing frame 3 are tightly fitted at the plug-in slot 201, when the rubber sealing frame 3 is fitted with the cabinet door 101, the external humid gas or dust cannot enter the high and low voltage switch cabinet body 1 from the gap between the high and low voltage switch cabinet body 1 and the cabinet door 101, thereby improving the sealing effect and avoiding the problem of loose sealing after the sealing gasket is used for a long time. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0025] like Figure 1As shown, in some embodiments, a cabinet door 101 is rotatably connected to the high and low voltage switch cabinet body 1, and a lead hole 102 is opened at the bottom of the high and low voltage switch cabinet body 1. The design of the high and low voltage switch cabinet body 1 meets the installation and use requirements of electrical equipment.

[0026] like Figure 2 As shown, in some embodiments, the connecting frame 2 is arranged on the high and low voltage switch cabinet body 1 facing the cabinet door 101, and a plug-in slot 201 is opened on the connecting frame 2. A plurality of threaded columns 202 are fixedly connected in the plug-in slot 201. The connecting frame 2 is used to cooperate with the rubber sealing frame 3 to achieve sealing of the high and low voltage switch cabinet body 1 and the cabinet door 101.

[0027] like Figure 3 As shown, in some embodiments, the rubber sealing frame 3 is slidably inserted into the insertion groove 201, and a rotating hole 301 is opened on the rubber sealing frame 3 to cooperate with the threaded column 202. The design of the rubber sealing frame 3 meets the use requirements and can avoid the problem that the traditional sealing gasket has an unsatisfactory rebound effect after being squeezed and flattened, and cannot tightly seal the distance between the high and low voltage switch cabinet body 1 and the cabinet door 101, resulting in poor sealing effect.

[0028] like Figure 4 As shown, in some embodiments, the adjusting pin 4 is composed of a pin head 401, a rotating column 402 and a threaded sleeve 403. The pin head 401 is fixedly connected to the rotating column 402. The rotating column 402 is rotatably connected in the rotating hole 301. The rotating column 402 is fixedly connected with a threaded sleeve 403. The threaded sleeve 403 is threadedly connected to the threaded column 202. The adjusting pin 4 can adjust the combined thickness of the rubber sealing frame 3 and the connecting frame 2 to meet the sealing requirements.

[0029] like Figure 5 As shown, in some embodiments, the lead sealing sleeve 5 is composed of a fixed disk 501 and a rubber sleeve 502. The fixed disk 501 is fixedly connected to the lead hole 102. The rubber sleeve 502 is provided on the fixed disk 501. The design of the lead sealing sleeve 5 meets the use requirements and can ensure good sealing at the lead hole 102, thereby improving the overall sealing effect.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
