DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. Example

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a transformer cover plate for the lower chamber in front of a cabinet comprises: a transparent plate 1, two protrusions 11 fixedly mounted on one side of the transparent plate 1 by screws, and a handle 12 rotatably connected to the two protrusions 11 by a pin shaft; and further comprises: an air bag 2, which is sleeved on the outer periphery of the transparent plate 1, and the air bag 2 is an annular structure, and an air nozzle 21 is arranged at one end of the outer periphery of the air bag 2, and a plug cover 22 is threadedly sleeved at one end of the outer periphery of the air nozzle 21, and the sealing performance of the air nozzle 21 can be further improved by the plug cover 22; an installation groove 3, which is opened on one side of the protrusion 11 close to the transparent plate 1, and a plug block 33 is vertically slid in the installation groove 3, and one side of the plug block 33 is fixedly mounted by screws There is an elastic reset member 34, one end of which is fixedly installed in the mounting groove 3 by screws, an air pipe 35 is arranged between the airbag 2 and the protrusion 11, one end of the air pipe 35 penetrates into the mounting groove 3 and abuts against the plug 33, a sealing gasket is adhered to the side of the plug 33 close to the air pipe 35, and the sealing gasket can further improve the sealing performance of the plug 33 when it abuts against the air pipe 35, a pulling component is arranged between the outer side of the handle 12 and the plug 33, and the handle 12 is pulled to separate the plug 33 from the air pipe 35 with the help of the pulling component; a vent 38 is opened on one side of the protrusion 11, and the vent 38 is communicated with the mounting groove 3.

[0020] Among them, by installing the transparent plate 1 in the high-voltage switch cabinet, the user can open the cabinet door of the high-voltage switch cabinet and check the electrical equipment in the high-voltage switch cabinet to effectively play a protective role and avoid electrical accidents. The handle 12 provided on the outer periphery of the transparent plate 1 through the protrusion 11 can provide a fulcrum so that the user can disassemble and assemble the transparent plate 1 in the high-voltage switch cabinet. At the same time, by providing an air bag 2 on the outer periphery of the transparent plate 1 and providing an air nozzle 21 on the air bag 2 that can inflate the air bag 2, the user can increase the friction force when installing the transparent plate 1 when installing the transparent plate 1 together with the air bag 2 in the switch cabinet, and by filling the air bag 2 with gas The firmness of the transparent plate 1 installed in the high-voltage switch cabinet can be further improved. At the same time, the internal air pressure of the air bag 2 is transmitted to the installation groove 3 through the air pipe 35 provided between the protrusion 11 and the air bag 2. The air pipe 35 can be effectively blocked by the blocking block 33 provided in the installation groove 3 through the limiting effect of the elastic reset member 34. The pulling assembly provided between the handle 12 and the blocking block 33 can separate the blocking block 33 from the end of the air pipe 35 by the pulling effect of the pulling assembly when the user pulls the handle 12, thereby achieving the purpose of rapid air deflation, so that the user can remove the transparent plate 1 from the high-voltage switch cabinet more conveniently. Example

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the difference from the previous embodiment is that the pulling assembly includes: a pull rope 36, which is fixedly installed on one side of the plug block 33 by screws, one end of the pull rope 36 passes through the protrusion 11 and is fixedly installed on the periphery of the handle 12 by screws, and a guide wheel 37 is rotatably connected to the installation groove 3 through a pin shaft, and the pull rope 36 slides on the periphery of the guide wheel 37; a guide rod 31 is fixedly installed on one side of the inside of the installation groove 3 by screws, and a positioning block 32 is fixedly installed on one end of the guide rod 31 by screws, and the plug block 33 is slidably sleeved on the periphery of the guide rod 31, and the guiding effect of the guide rod 31 can improve the tightness of the plug block 33 when blocking the trachea 35.

[0022] Among them, by providing a pull rope 36 that can be guided by a guide wheel 37 between one side of the outer periphery of the handle 12 and the plug 33, when the user moves the handle 12 from a vertical state to a horizontal upward state, the plug 33 in the mounting groove 3 can be effectively pulled downward, thereby causing the air bag 2 connected to the air pipe 35 to deflate, so that the user can remove the transparent plate 1 from the high-voltage switch cabinet, thereby further improving the convenience of the user in removing the transparent plate 1.

[0023] Working principle: When in use, by installing the transparent plate 1 into the high-voltage switch cabinet, the user can open the cabinet door of the high-voltage switch cabinet and check the electrical equipment in the high-voltage switch cabinet to effectively play a protective role and avoid electrical accidents. The handle 12 provided on the outer periphery of the transparent plate 1 through the protrusion 11 can provide a fulcrum so that the user can disassemble and assemble the transparent plate 1 in the high-voltage switch cabinet. At the same time, by providing an air bag 2 on the outer periphery of the transparent plate 1 and providing an air nozzle 21 on the air bag 2 that can inflate the air bag 2, the user can increase the friction force when installing the transparent plate 1 together with the air bag 2 in the switch cabinet, and by filling gas into the air bag 2, the transparent plate 1 can be further installed in the high-voltage switch cabinet. The firmness is ensured. At the same time, the air pipe 35 provided between the protrusion 11 and the air bag 2 allows the internal air pressure of the air bag 2 to be transmitted to the mounting groove 3. The plug 33 provided in the mounting groove 3 can effectively block the air pipe 35 through the limiting effect of the elastic reset member 34. A pull rope 36 that can be guided by a guide wheel 37 is provided between one side of the outer periphery of the handle 12 and the plug 33, so that when the user moves the handle 12 from a vertical state to a horizontal upward state, the plug 33 in the mounting groove 3 can be effectively pulled downward, thereby causing the air bag 2 connected to the air pipe 35 to be deflated, so that the user can remove the transparent plate 1 from the high-voltage switch cabinet, thereby further improving the convenience of the user in removing the transparent plate 1.
