Description

An observation mirror for electrical inspection

technical field

The utility model relates to an observation mirror, in particular to an observation mirror for electrical inspection.

Background technique

In each station area where the electric meter is installed, there is a certain distance between the meter box and the height of the person. Due to the problem of sight, in order to clearly check the usage of the electric meter, it is often necessary to climb high. It is inconvenient for electricity inspection and meter reading personnel. The wiring of the ammeter itself is dense and complicated, and there is an integrated circuit board on the wiring board inside the meter. It is not suitable to accurately judge whether the wiring inside the meter has been changed, which may easily cause wrong judgments in the anti-stealing work. At the same time, it is difficult to see the operating data of the meter. Meter reading and electricity inspections caused delays.

Utility model content

The technical problem to be solved by the utility model is to provide an observation mirror for electrical inspection, which has the functions of extending the field of view, collecting, enlarging, and illuminating the dial, avoiding the danger caused by the climbing operation and the trouble of carrying the climbing tools, and is suitable for near Distance meter reading and electricity inspection work, it is easy to find out the wiring inside the meter without authorization, and it is convenient for detailed investigation, which greatly improves the work efficiency and anti-stealing ability; the structure is simple, easy to carry, and has a high promotion value.

The technical scheme that the utility model takes is:

An observation mirror for electrical inspection, comprising an inspection tube 1, an observation tube 2, two plane mirrors 3, an illuminating lamp 4 and a magnifying glass 5; It is designed to be larger than the diameter of the detection tube 1, and the side walls of the detection tube 1 and the observation tube 2 are arranged in a one-to-one correspondence along the height direction, and the threaded holes 6 are arranged in a row along the height direction. After adjusting the vertical distance , the probe tube 1 and the observation tube 2 are fixedly connected by screws 7; the plane mirror 3 is fixed at a right-angle bend in the probe tube 1 and the observation tube 2 at 45°; the lighting lamp 4 is fixed on the tube wall of the probe end 6; the magnifying glass 5 is fixed On the edge of the probe end 6 of the probe tube 1 .

The beneficial effects produced by adopting the above-mentioned technical scheme are:

1. The utility model has the functions of extending the field of vision, collecting, zooming in, and illuminating the dial. It can clearly see the small changes in the meter body, the identification parameters and operating data outside the watch case, and avoids the danger caused by climbing operations and the trouble of carrying climbing tools. , suitable for short-distance meter reading and electricity inspection work, easy to find out the wiring inside the meter without permission, and facilitate detailed investigation, which greatly improves work efficiency and anti-stealing ability.

2. The height of the detection tube and the observation tube can be adjusted according to the requirements of use, which is flexible and convenient.

3. The utility model has a simple structure, is easy to carry, and has a very high promotional value.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Referring to accompanying drawings 1-3, an observation mirror for electrical inspection includes a detection tube 1, an observation tube 2, and two plane mirrors 3; both the detection tube 1 and the observation tube 2 are in an "L" shape; the plane mirror 3 is fixed at 45° At the right-angle bend in the probe tube 1 and the observation tube 2.

In order to make the probe tube 1 and the observation tube 2 connected to each other, and the distance between the two plane mirrors 3 can be properly adjusted, the diameter of the observation tube 2 is designed to be greater than the diameter of the probe tube 1, and a hole is placed on the side walls of the probe tube 1 and the observation tube 2 Correspondingly, a plurality of threaded holes 6 are arranged, and the threaded holes 6 are arranged in a row along the height direction. After the vertical distance is adjusted, the detection tube 1 and the observation tube 2 are fixedly connected by fixing pins.

The observation mirror for electric inspection also includes a lighting lamp 4; the lighting lamp 4 is fixed on the barrel wall of the probe end 6.

The observation mirror for electrical inspection also includes a magnifying glass 5, and the magnifying glass 5 is fixed on the edge of the probing end 6 of the probing tube 1.

When in use, insert the probe tube 1 into the observation tube 2, after adjusting the vertical distance, fix the probe tube 1 and the observation tube 2 through the fixed pin, turn on the light 4, and align the probe end 6 of the probe tube 1 with the object to be probed. For the watch case, adjust the observation tube 2 to be parallel to the inspector's line of sight, and investigate the situation in the watch case through the magnifying effect of the magnifying glass 5 .

The utility model utilizes the reflection principle of light to achieve the purpose of extending the field of vision, uses lighting lamps to illuminate the dial, and uses a magnifying glass to enlarge the dial and the watch box, so that the small changes in the meter body, the marking parameters outside the watch case and the operating data are clearly visible. It provides convenience for the detection work of the meter box, and greatly improves the work efficiency and anti-stealing ability.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed by the utility model Replacement should be covered within the protection scope of the present utility model.
