Observation device for electric meter box

Abstract

The invention provides an observation device for an electric meter box. The electric meter box includes a casing, a door body and an electric meter; the electric meter is disposed in the casing; the observation device is disposed on the door body and is located below the electric meter; the observation device includes a mounting plate, a universal ball and an observation mirror; the center of themounting plate is provided with a mounting hole; the universal ball is disposed in the mounting hole and rotates in the mounting hole; the center of the universal ball is provided with a columnar holepenetrating through the ball; the observation mirror includes a lens barrel, an eyepiece and an objective lens; the lens barrel is disposed in the columnar hole and comprises a fixed barrel and a telescopic barrel; one end of the fixed barrel is connected with the telescopic barrel and the other end is provided with the objective lens; the objective lens is exposed to the columnar hole, and the end, away from the fixed barrel, of the telescopic barrel is provided with the eyepiece. The device which can rotate for multiple angles and fulfill a magnifying function for the electric meter is arranged on the door body of the electric meter box, so that power workers can read readings of the electric meter and observe the safety conditions in the electric meter box conveniently.

Description

technical field [0001] The invention relates to the field of electric meter boxes, in particular to an observation device for electric meter boxes. Background technique [0002] Meter boxes are widely used in power facilities and equipment. Cable branch boxes, low-voltage distribution boxes, water pump control boxes, communication device cabinets, street lamps and traffic light control boxes, multi-functional metering boxes, integrated distribution boxes, and capacitors in public power grids are widely used. Compensation boxes, terminal boxes, wall-mounted junction boxes, metering boxes, etc. all use the meter box. The meter box is a kind of electronic meter and mechanical meter that can be directly fixed on the wall or installed on the pole, and can be installed in any specification. , Install leakage protectors, junction boxes, leakage switches or RCL fuses, and power distribution devices for isolating switches. The main components of the meter box are ABS engineering pla...

Problems solved by technology

[0003] The current meter boxes are all fixedly installed on the wall or on the pole, and the installation height is higher than the normal height of the human body. When checking the meter box, due to the high height, it is extremely inconvenient to check the operation. Operation with the help of ladders and other related items will bring great difficulties to the staff, affect the normal work effect, and cause the reduction of work efficiency. In order to avoid the occurrence of the above situation, the present invention proposes a observation device
