Ratchet strip and ratchet type meter reading bracket

Abstract

The invention discloses a ratchet strip and ratchet type meter reading bracket which comprises a sleeve and a first ratchet strip. The sleeve is a long-strip-shaped pipe with an upper opening and a lower opening. The upper end of the sleeve is provided with a forwards-protruding boss. The first ratchet strip is a long-strip-shaped ratchet strip with downward ratchet teeth arranged on the front side face, is mounted in the sleeve, and can move up and down along an inner cavity of the sleeve. A long-strip-shaped opening is formed in the right side face of the sleeve. The first ratchet strip is fixedly connected with a platform through the long-strip-shaped opening. The platform is horizontally placed and can move up and down along the first ratchet strip. The ratchet strip and ratchet type meter reading bracket further comprises a first ratchet which is mounted in front of the lower end of the sleeve and penetrates through an opening formed in the corresponding position of the sleeve to be matched with the first ratchet strip. A shell is arranged on the periphery of the first ratchet. A ratchet shaft of the first ratchet is mounted on the shell through a bearing. A first handle is arranged at the right end of the ratchet shaft of the first ratchet. The ratchet strip and ratchet type meter reading bracket can assist meter reading personnel in aligning a meter reading device to an electric energy meter at a high position.

Description

technical field [0001] The invention relates to a meter reading tool, in particular to a ratchet and ratchet type meter reading bracket. Background technique [0002] Nowadays, the multi-rate energy meter is an indispensable energy metering product under my country's current electricity saving and planned electricity consumption policies. The communication interface of the multi-rate energy meter generally has both an infrared interface and an RS485 interface. Infrared communication has the advantages of intuition, easy operation, and high reliability. It is the most common communication method used in electric energy meters, and it is an effective means to realize the meter reading function between the electric energy meter and the meter reading device. [0003] When using an infrared meter reading device to read the electric energy meter, the distance and angle between the meter reading device and the electric energy meter are the main factors affecting the reliability of ...

Problems solved by technology

[0003] When using an infrared meter reading device to read the electric energy meter, the distance and angle between the meter reading device and the electric energy meter are the main factors affecting the reliability of the data. Keeping the infrared port at a vertical angle, especially when the energy meter is installed at a high level, will bring great difficulties to the meter reading work, so the production design can easily realize the meter reading of the higher energy meter. This kind of meter reading bracket has become an urgent need in social life
