Problems solved by technology
[0003] However, the existing portable small-scale meter reading terminals still have certain defects during use. For example, because the operator usually reads the meter in an area, and the working hours are long, the operator will often go out when holding the meter reading terminal hand. Sweat not only causes discomfort and operational obstacles during use, but also easily flows into the device and causes a short circuit, eventually causing damage to the device

The invention discloses a portable small-scale meter reading terminal used in the electric power industry, which includes a control handle body, a meter reading terminal body is installed on the upper end of the control handle body, and a plurality of control handles are installed on the side wall of the control handle body. button, the side wall of the meter reading terminal body is equipped with a warning light, the side wall of the control handle body is provided with a bar-shaped groove, and the inner bottom of the bar-shaped groove is fixedly connected with a telescopic air bag. The upper end is fixedly connected with a block, and the side wall of the block is provided with a channel communicating with the inside of the telescopic air bag. In the present invention, the slide plate is moved back and forth, so as to pump air continuously into the telescopic air bag, and when a certain amount of air is stored in the telescopic air bag, the pressure relief valve can be opened, so that the air can be ejected from the air outlet at a high speed, thereby The sweat in the palm is evaporated quickly, which not only improves the comfort of the operator, but also prevents the sweat from flowing into the device and causing damage to various components.
Description
technical field [0001] The invention relates to the technical field of equipment related to small-scale meter reading, in particular to a portable small-scale meter-reading terminal used in the electric power industry. Background technique [0002] Compared with the traditional means of manual meter reading, the existing portable small meter reading terminal has outstanding advantages such as fast reading speed, high calculation accuracy, good meter reading simultaneity, and can be directly connected to the business computer network, so it is greatly appreciated. welcome. [0003] However, the existing portable small-scale meter reading terminals still have certain defects during use. For example, because the operator usually reads the meter in an area, and the working hours are long, the operator will often go out when holding the meter reading terminal hand. Sweat not only causes discomfort and operational obstacles during use, but also easily flows into the device and ca...
