Embodiment 1

[0018] Example 1: as Figure 1-Figure 3 As shown, the box body of the high-voltage electrical switch product mechanism box includes an observation window panel 1, an elastic seal and a box shell 2 fixedly matched with the observation window panel 1, and the elastic seal used is an elastic gasket 3, and the observation window There are three turnbuckles 11 on the edge of the panel on one side of the mechanism box, and the distance between two adjacent turnbuckle structures is equal. The turnbuckles are evenly distributed on the observation window panel, which can make the observation window panel more evenly stressed. Fixed better. The observation window panel 1 and the turnbuckle 11 are integrally formed of polyethylene material through an injection molding process, the process is simple, the production cycle is short, and it is suitable for mass production. The box shell 2 is provided with three card slot holes that cooperate with the rotary buckles on the observation window...

Embodiment 2

[0020] Embodiment 2: as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is only that the slot hole on the mechanism box is a large round hole, and three positioning segments 21 are arranged on the edge of the large round hole to cooperate with the rotary buckle. It is the same as described in Embodiment 1 and will not be repeated here.

Abstract

The invention relates to a high voltage electrical switch product mechanism box body which comprises an observation window panel, an elastic seal and a box body casing. A spinner is arranged on the observation window panel. A clamp slot hole which is in clamp connection matching with the spinner on the observation window panel is arranged in the box body casing. The elastic seal is sandwiched between the observation window panel outside the spinner and the box body casing. The elastic seal does not require a seal gasket in a special structure or a seal ring in a special structure. The observation window panel and the mechanism box casing body are not fixed through bolts, which has the advantages of low cost and simple structure. According to the invention, the problems of low fixing intensity, high cost and low bolt-fixed observation window assembly efficiency of the existing seal ring type observation window applied to the high voltage electrical switch product mechanism box body are solved.

Description

technical field [0001] The invention relates to the field of mechanism boxes of high-voltage electrical switch products, and particularly designs a box body of the mechanism box of high-voltage electrical switch products. Background technique [0002] In high-voltage electrical switch products, the box body of the high-voltage electrical switch product mechanism box needs to be equipped with an observation window for observing the immediate state of the mechanism, so that the operator can accurately judge the on-off status of the high-voltage electrical switch product, and avoid accidents caused by misuse. Power grid, personal safety issues. The observation window of the box body of the high-voltage electrical switch product mechanism box must be able to ensure the waterproof, moisture-proof, and dust-proof functions of the box body. When the basic functions are satisfied, the observation window is also required to have strong anti-aging, high transparency, and high strength...
