DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1 , Figure 2A rat-proof switch cabinet includes a cabinet body 1 and a cabinet door 2. A threading hole 3 is provided on the back of the cabinet body 1. A support ring 4 is provided in the threading hole 3 along its circumference. An elastic airbag ring 5 is fixedly connected to the inner wall of the support ring 4 along its circumference. When the main cable passes through the airbag ring 5 and enters the cabinet body 1, the airbag ring 5 can be tightly wrapped around the main cable, thereby sealing the gap between the main cable and the wiring hole, preventing mice from entering the switch cabinet, reducing the risk of electrical facilities being gnawed by mice, and thus improving the stability of the switch cabinet.

[0021] Reference Figure 2 , Figure 3 The airbag ring 5 is connected with an air inlet and outlet nozzle 6, and the air inlet and outlet nozzle 6 is used to connect with the connector of an external air pump. When the main cable is threaded, the gas in the airbag ring 5 can be discharged through the air inlet and outlet nozzle 6, so that the main cable can be quickly inserted into the cabinet 1. After the main cable is inserted into the cabinet 1, the airbag ring 5 can be re-inflated by the air pump, and the airbag ring 5 can be tightly wrapped around the main cable.

[0022] Reference Figure 2 , Figure 3 The support ring 4 has an annular accommodating chamber 7 inside, which is filled with rat-repelling granules. The side wall of the support ring 4 is provided with a plurality of air holes 8, which are respectively connected to the accommodating chamber 7, and the outer diameter of the rat-repelling granules is larger than the inner diameter of the air holes 8. At the same time, the support ring 4 is provided with a filling hole 9 connected to the accommodating chamber 7, and a sealing plug 10 is threadedly connected to the filling hole 9, so that the user can add rat-repelling granules to the accommodating chamber 7.

[0023] By arranging rat repellent granules in the accommodating cavity 7 inside the support ring 4, rats can be driven away, reducing the risk of rats approaching the switch cabinet, thereby reducing the risk of the main cable and the airbag ring 5 being eaten, thereby improving the stability of use.

[0024] Reference Figure 2 , Figure 3 The support ring 4 is movably inserted into the threading hole 3 and is detachably connected to the cabinet 1, so that the airbag ring 5 can be replaced after aging, thereby ensuring the anti-rat capability. At the same time, when the outer diameter of the main cable matches the inner diameter of the threading hole 3, the support ring 4 and other components can be disassembled, which can provide users with flexible selection.

[0025] Reference Figure 2 , Figure 3 A mounting ring 11 is fixedly sleeved on the support ring 4 for resting against the outer wall of the cabinet 1 , and a plurality of fastening screws 12 are threadedly connected to the mounting ring 11 . A plurality of fastening grooves 13 are opened on the outer wall of the cabinet 1 , and the fastening screws 12 can be threadedly matched with the corresponding fastening grooves 13 .

[0026] Reference Figure 2 , Figure 3 A pair of positioning columns 14 are fixedly connected to the outer wall of the cabinet 1, and the pair of positioning columns 14 are symmetrically distributed on both sides of the wiring hole. Two positioning holes 15 are opened on the support ring 4. When the two positioning columns 14 are respectively inserted into the corresponding positioning holes 15, the multiple fastening screws 12 are aligned one by one with the multiple fastening grooves 13, so that the user can quickly determine the installation position of the support ring 4, thereby improving the assembly efficiency of the support ring 4.
