A switch cabinet door with a glass window

Abstract

A switch cabinet door with a glass window comprises a switch cabinet door plate (7) and a glass plate (5). An observing window is arranged on the switch cabinet door plate (7), and the glass plate (5) is arranged on the observing window. The switch cabinet door further comprises a rectangular frame strip assembly (3) and an elastic pressing plate (2), wherein the rectangular frame strip assembly (3) is enclosed by four U-shaped locating frame strips, and the rectangular frame strip assembly (3) surrounds the observing window. The elastic pressing plate (2) comprises a base plate and a fin plate, wherein the base plate and the fin plate form a 135-degree angle. The end portion of the fin plate tightly presses the glass plate (5), and the base plate and the U-shaped locating frame strips are detachably connected through self-tapping screws. Through adoption of the structure, lever force is generated by means of a simple folding angle structure of the pressing plate, and the pressing plate can enable glass to be tightly pressed in the rectangular frame strip assembly on the reverse side of the switch cabinet door plate. The switch cabinet door is convenient to operate, and can prevent the glass plate from falling off in the transporting and carrying process due to a buffering function of the pressing plate.

Description

Technical field [0001] The invention belongs to the technical field of power equipment, and specifically relates to a high and low voltage switch cabinet, especially the clamping and fixing of 6.0 mm thick glass on the observation window of the metering cabinet door. Background technique [0002] For the high and low voltage switch cabinets of power equipment, especially the electric energy metering cabinet, a transparent glass observation window is usually required on the door to observe the reading of the electric energy meter, the transformer ratio and the connection direction of the metering terminal. Because the metering cabinet needs to be sealed and sealed , To prevent electricity theft and damage, the glass on the door should be thick enough, such as 6.0mm thick inorganic transparent glass or explosion-proof tempered glass, which involves the clamping and fixing of this kind of glass on the switch cabinet door. At present, there are many ways to clamp switchgear glass, bu...

AI Technical Summary

Problems solved by technology

At present, there are many methods of clamping glass in switchgear, but many of them have defects. For example, the more commonly used ones are: U-shaped rubber strips nested around the window, welding studs on the back of the door panel, pressure frames or L-shaped mounting clips through studs and nuts. The strip is fixed to the door panel, and the four sides of the glass are directly hugged and pressed by the pressure frame or the L-shaped clamping strip.

The main defect of this clamping method is that the mechanism is relatively complicated, the clamping is not simple and reliable enough, the U-shaped rubber strips nested at the four corners of the window are easy to wrinkle, which affects the appearance, and the beginning and the end of the rubber strips need to be pasted with glue, etc.; especially because Only one side of the glass is tightly attached by the rubber strip, but the other side is in hard-to-hard contact with the metal platen. The clamping force is uneven. If the bolt is tightened too much force during the clamping process, the glass may be easily broken, which directly causes the bolt not to tighten too much. tight and loose

Therefore, for the clamping of thick and heavy glass, the above-mentioned mechanism is not reliable enough. If severe vibration occurs during the handling or transportation of the switchgear, the glass may fall off or break.
