Detailed Description

As shown in fig. 1 to 4, in this embodiment, the utility model includes a box body 1, an outer door 2, an inner door 3, a flame-retardant transparent partition plate 4, and a flame-retardant wire casing 5.

In this embodiment, outer door 2 is by the preparation of cold-rolled sheet steel, outer door 2 includes tool to lock 21, transparent observation window 22 and sealed rubber ring 23, tool to lock 21 is located three positions about the chamber door, and the lock adopts the rotation to lock from tightening up, takes waterproof rubber cover. The transparent observation window 22 is located on the upper portion of the box door and is of a rectangular structure, the observation window is a transparent acrylic plate, the acrylic plate is fixed to the inner side of the door through screws, and the periphery of the transparent acrylic plate is provided with a sealing rubber edge. The transparent observation chamber is used for observing the state of the internal switch under the state of not opening the door. The sealing rubber ring 23 is of a rectangular structure and is arranged on the outer door to prevent external liquid from flowing into the box body.

In this embodiment, interior door 3 is located the outer door inside, leaves hole site 31 and tool to lock 32 on the interior door, and installation hole site 31 is used for installation instrument and switch operation handle, and state knowledge etc. is convenient for observe the operating condition and the instrument data of block terminal switch under the inside condition not opening. The lock is an inner upper part and a lower part.

In this embodiment, transparent fire-retardant baffle 4 is the rectangle structure, and there are four mounting holes 41 of mounting hole vertical direction both sides, the upper and lower extreme of transparent fire-retardant baffle is equipped with yellow insulating handle 42, fixes on transparent fire-retardant baffle 4 through pasting the mode.

In this embodiment, fire-retardant wire casing 5 is the fire-retardant wire casing, is located the block terminal right side, sets up according to the function, divide into fuse groove 51, three-phase switch groove 52, single-phase switch groove 53.

In this embodiment, outer door 2 links to each other with the block terminal casing through sealed rubber ring, consolidates through being located three tool to lock 21 about the outer door, and the fire-retardant transparent insulating barrier of 2mm will expose female arranging outside and keep apart, installs fixedly through predetermined installation hole site. The lock for the outer door of the lock box adopts a rotary self-tightening lock with a waterproof rubber cover. The outer door 2 adopts the structure of the transparent observation window 22, so that the opening times of the lock 21 can be reduced, the service lives of the lock and the hinge of the distribution box can be prolonged, and the service life of the distribution box is further prolonged.
