[0034] In order to effectively fix the installation base plate 4 on the outside of the cabinet 1, the installation component includes a fixing plate 3 fixedly connected to the outside of the fixing frame 2, the inside of the fixing plate 3 is fixedly connected to the sliding rod 17, the inside of the fixing plate 3 is provided with a contact plate 18, the inside of the contact plate 18 is provided with a guide groove for the sliding rod 17 to move, the outside of the sliding rod 17 is sleeved with a return spring 19, the return spring 19 is in contact between the contact plate 18 and the fixing plate 3, the outside of the contact plate 18 is symmetrically provided with side plates 20, the outside of each two side plates 20 is fixedly connected with a pull plate, the opposite sides of the two contact plates 18 are symmetrically provided with plug rods 21, the contact surfaces of the fixing plate 3 and the fixing frame 2 are provided with guide grooves for the plug rod 21 to move, the inside of the L-shaped plate 5 is provided with a guide groove for the plug rod 21 to move, when it is necessary to install the base plate 4 When it is fixedly installed on the outside of the cabinet 1, you only need to pull the pull plate first. At this time, the pull plate will drive the side plate 20 to move synchronously, and the side plate 20 will drive the contact plate 18 to move synchronously on the outside of the slide rod 17. During the movement of the contact plate 18, the reset spring 19 will be squeezed, and the contact plate 18 will also drive the insertion rod 21 to move synchronously. At this time, insert the L-shaped plate 5 into the inside of the fixed frame 2, and then release the pull plate. At this time, the reset spring 19 is reset, driving the contact plate 18 to move synchronously, and the contact plate 18 drives the insertion rod 21 to move synchronously.

During the movement of the contact plate 28, the contact spring 29 will be squeezed. At this time, the movable plate 7 is pulled again, and the movable plate 7 will drive the bottom block 30 to move synchronously. When the movable plate 7 is in a horizontal state, the pull ring is released again. At this time, the contact spring 29 is reset, driving the contact plate 28 and the mounting rod 27 to move synchronously. When the mounting rod 27 is inserted into the guide groove inside the bottom block 30, the bottom block 30 can be fixed. At this time, the position of the movable plate 7 can be fixed, so that the rainproof cloth 8 can effectively play a protective role.
