Abstract

The invention discloses an external power supply device for gas meter detection. The external power supply device comprises a left clamping plate and a right clamping plate. The left clamping plate and the right clamping plate are connected through a rotation shaft and a torsion spring. The left clamping plate and the right clamping plate are respectively provided with rotation shaft installationholes. The rotation shaft is inserted into the rotation shaft installation holes in the left clamping plate and the right clamping plate; the torsion spring is sleeved on the rotation shaft; and one end of the torsion spring is connected with the left clamping plate, and the other end of the torsion spring is connected with the right clamping plate. One end of the right clamping plate is providedwith two conducting bolts. The two conducting bolts are a positive bolt and a negative bolt respectively. The output ends of the two conducting bolts pass through the right clamping plate and extend from the lower surface of the right clamping plate. The input end of each conducting bolt is sleeved by a single-head soldering lug. After the conducting bolts are sleeved by the single-head solderinglugs, the single-head soldering lugs are fixed through nuts; and each single-head soldering lug is connected with a wire. The external power supply device for gas meter detection can realize fast power on and power off of each gas meter, and has the advantages of being simple in structure, convenient to use and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of gas meters, in particular to an external power supply device for gas meter detection. Background technique [0002] During the detection process of the smart gas meter, it is necessary to power on and off the gas meter to check whether the smart gas meter can work normally. Generally, the smart gas meter needs 3-4 dry batteries to supply power. Battery-powered, the process of installing and removing the battery is cumbersome, and the operation is inconvenient, and it will also affect the detection efficiency of the gas meter. Therefore, a device that can quickly power on and power off the gas meter is needed to improve the detection efficiency of the gas meter. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology, and provide an external power supply device for gas meter detection, which can quickly power on...
