Summary of the invention
The object of this invention is to provide a kind of casing of high-voltage electrical apparatus switch product mechanism case, to solve at present for the problem that sealing ring type observation window constant intensity is not high, cost is high and bolt fastening observation window efficiency of assembling is low of the casing of high-voltage electrical apparatus switch product mechanism case.
Technical scheme of the present invention is: a kind of casing of high-voltage electrical apparatus switch product mechanism case, comprise observation window panel, elastic sealing element and cabinet shell, described observation window panel is provided with spinner, cabinet shell is provided with the draw-in groove hole with the spinner snap-fit engagement on observation window panel, elastic sealing element is clipped between the observation window panel of spinner periphery and cabinet shell.
Described draw-in groove hole comprises positioning section and for coordinating the angular adjustment guide section regulating observation window panel visual angle with spinner.
Described observation window panel has two spinners at least, and spinner is evenly distributed on observation window panel.
Described observation window panel passes through injection mo(u)lding.
Described draw-in groove hole number is identical with spinner quantity.
Described cabinet shell only has a draw-in groove hole.
Beneficial effect of the present invention is: the casing of described high-voltage electrical apparatus switch product mechanism case, comprise observation window panel, elastic sealing element and cabinet shell, described observation window panel is provided with spinner, cabinet shell is provided with the draw-in groove hole with the spinner snap-fit engagement on observation window panel, elastic sealing element is clipped between the observation window panel of spinner periphery and cabinet shell, compare with ring structure formula observation window in prior art, the elastic sealing element be arranged between spinner and draw-in groove hole does not need the sealing gasket adopting special construction, sealing ring, the cost of elastic sealing element is low, and can make, between observation window and casing housing, there is higher constant intensity by spinner and draw-in groove hole snap-fit engagement, compare with bolt fastening observation window in prior art, by the mode of spinner and the clamping of draw-in groove hole, do not need dismantling device just can complete assembling, dismounting, do not need to use multiple bolt to fix between observation window panel and cabinet shell simultaneously, simply easy to operate, improve efficiency of assembling.
Further, described draw-in groove hole comprises positioning section and for coordinating the angular adjustment guide section regulating observation window panel visual angle with spinner, spinner coordinates the visible angle that can regulate observation window panel with angular adjustment guide section, adjusting angle is convenient, avoids the phenomenon of station misregister.
Further, described observation window panel has two spinners at least, and spinner is evenly distributed on observation window panel, observation window panel can be made stressed evenly, fixed effect is better.
Further, observation window panel is by injection mo(u)lding, and technique is simple, with short production cycle, is applicable to producing in enormous quantities.
