Problems solved by technology
The observation windows of the traditional method are mostly the combination of transparent plexiglass, card slots, sealing strips, etc. The disadvantage is that the sealing strips are easy to age and fall off, and the gap sealing degree of the observation window is not enough to cause dirty discharge; And the installation process is easy to be damaged and replaced frequently, especially the observation window of outdoor power distribution equipment, its damage and aging time are faster, the waterproof performance of the equipment is reduced, and it is easy to cause electrical safety accidents

Embodiment Construction
[0021] refer to Figure 1 to Figure 6 , the present invention is an observation window structure of power distribution equipment, comprising a door panel 1, a notch arranged on the door panel 1 and a glass plate 2 for sealing the notch. The size of notch is less than the size of glass plate 2, now only need find a way to allow the edge of glass plate 2 to be close to the periphery of notch; Each corner plate 3 includes a connecting portion 31 fixed on the door panel 1 and a clamping portion 32 supporting the edge of the glass plate 2. Several notches are arranged at intervals on each clamping portion 32, and pins 8 are detachably arranged in each notch. A part of each pin 8 fits and presses against the back of the glass plate 2 . The corner plate 3 is used as a fixed base, and the glass plate 2 is clamped together with the door plate 1 through the pin 8, and it is no longer necessary to use the sealing strip to assist in fixing the glass plate 2. Wherein the lowermost corner...

The invention discloses a power distribution equipment observation window structure comprising a door plate, a notch arranged on the door plate and a glass plate for blocking the notch, wherein the door plate is provided with corner plates at four corners of the glass plate, each angle plate comprises a connection part fixed on the door plate and a clamping part for carrying the edge of the glassplate, a plurality of gaps are arranged on the clamping parts at intervals, a dowel is detachably arranged in each gap, and the part of each dowel is adhered to and pressed against the back of the glass plate. The corner plates are used as fixed substrates and cooperated with the door plate to jointly clamp the glass plate via the dowels, the glass plate does not need to be fixed with the aid of sealing strips, the installation structure is simplified, the production efficiency is improved, and the dustproof and waterproof levels of the power distribution equipment observation window structureare superior to these of the traditional installation mode; and when in use, only the structure and layout of the gaps need to be optimized, and the installation speed and stability of the dowels canbe improved. The power distribution equipment observation window structure provided by the invention is applied to the field of window structures.
Description
technical field [0001] The invention relates to the field of window structures, in particular to an observation window structure for power distribution equipment. Background technique [0002] Low-voltage power distribution cabinets and distribution boxes are widely used in power distribution, lighting, metering and other power consumption occasions in factories, mines, enterprises and civil buildings. For the convenience of power distribution equipment in the process of operation, monitoring and maintenance, setting a transparent observation window at an appropriate position on the housing is an indispensable content in the process of meeting the national industry standards and satisfying users. The observation windows of the traditional method are mostly the combination of transparent plexiglass, card slots, sealing strips, etc. The disadvantage is that the sealing strips are easy to age and fall off, and the gap sealing degree of the observation window is not enough to ca...
