Observation mirror for electric inspection

Abstract

The invention discloses an observation mirror for electric inspection. The observation mirror comprises a plane mirror, a view cylinder and an observation cylinder. An intermediate cylinder is arranged between the view cylinder and the observation cylinder. The view cylinder has an L-shaped structure; and the observation cylinder is arranged vertically. An extension cylinder is installed movably in the view cylinder; and a view frame is in threaded connection with one end of the extension cylinder. A push rod motor is welded to the bottom of the view cylinder; a rectangular block is welded tothe bottom of the extension cylinder; an output shaft of the push rod motor is welded to one side of the rectangular block. A limiting block is welded to the top of the view cylinder; a limiting holeis formed in the limiting block; and a limiting rod is installed in the limiting hole in a sliding manner. According to the invention, the observation mirror has high economy and practicability; whenthe space between the view frame and an electric meter is adjusted and the view frame rotates, observation is carried out comprehensively and clearly, so that the observation difficulty is reduced; the limiting rod is used for limiting the extension cylinder and an arc block limits the rotation; and with an illumination lamp, light is changed and thus observation is carried out clearly in details.

Description

technical field [0001] The invention relates to the technical field of electric meter observation, in particular to an observation mirror for electric inspection.

[0002] At present, when checking the ammeter, the staff often use the climbing escalator to carry out the climbing operation because of the installation height of the ammeter. When checking, both hands need to record the work at the same time. In this way, the workload of the staff is unavoidable. increase, and there are certain security risks

[0003] After retrieval, the publication (announcement) number: CN207867120U's patent document discloses an observation mirror for electrical inspection, including a plane mirror. There are two plane mirrors and they are respectively installed in the inspection tube and the observation tube. Lamp and magnifying glass, the plane mirror is stuck in a rectangular insert, and the inspection tube and the observation tube are two identical "L"-shaped two-way tubes, and the corners of the two-way tubes are provided with rectangular sockets. The acute angle between the socket and the two sides of the two-way cylinder is 45°, and the two two-way cylinders are connected with an intermediate cylinder with a metal buckle. There are at least two intermediate cylinders and they are also made of metal. buckle connection, but the observation mirror in the above-mentioned patent documents is not easy to adjust, because the observer is at a high place during observation, it is not easy to move, it is necessary to adjust the distance between the observation mirror and the meter, and adjust the clarity of observation. Restrictions lead to the inability to better adjust the distance between the observation mirror and the meter, and it is not convenient to adjust the angle of observation, which increases the difficulty of observation and thus cannot meet the higher needs of users
