Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2 to 5, the structure of the insulation shield apparatus of the present invention is mainly composed of the following 4 parts: rear lower sealing plate 1, backing plate 2, slide 3, clamp plate 4. In addition, a nylon bolt 5, a nylon nut 6 and a nylon washer 7 are arranged. The main functions of the components are as follows: the rear lower sealing plate 1 is a base for mounting the backing plate 2, the sliding plate 3 and the pressing plate 4. The rear lower closing plate 1 is arranged at the rear lower part of the cabinet body and is provided with a square hole with the size of 110 x 120 mm. The backing plate 2, the sliding plate 3 and the pressing plate 4 are connected to the rear lower sealing plate 1 through nylon bolts 5, and the installation sequence, the installation position and the like are shown in fig. 5. The backing plate 2 is mounted on the rear lower closure plate 1. The material is transparent polycarbonate plate, and slide 3 is cushioned up to backing plate 2, makes things convenient for the slip of slide 3. The sliding plate 3 is padded on the backing plate 2 and pressed by the pressing plate 4, so that the sliding plate 3 slides up and down. The main function of the sliding plate 3 is to open the open hole through up-and-down sliding when the electric wire is assembled and disassembled, thereby facilitating the operation. The pressing plate 4 is used to press the slide plate 3 so that the slide plate 3 slides inside. When the insulation protection plate device is not required to be overhauled and maintained, the sliding plate 3 automatically slides down to block the open hole.
