The invention discloses conveniently installed high-low pressure electric energy measuring equipment. The equipment comprises a mounting plate, wherein the surface of the mounting plate is fixedly connected with a mounting cabinet, an inner cavity of the mounting cabinet is provided with a measuring device, the top of the measuring device is fixedly connected with a fixing block, an inner cavity of the fixing block is provided with a rotating rod, the left side of the rotating rod penetrates through the fixing block and is fixedly connected with a rotating handle, and the surface of the rotating rod is sleeved with a bearing. The conveniently installed high-low pressure electric energy measuring equipment has the advantages that through the arrangement of a rotary disk, rotating rod, steelwire rope, fixing plate, first spring, clamping pin, moving plate, clamping groove, second spring, moving rod and fixing handle, the device can achieve the effect of convenient installation, and theproblems are solved that most existing electric energy measuring meters in the market are in integrated fixed installation with mounting cabinets and do not have a function of being installed conveniently; fixing bolts need to be used when the measuring meters are installed; severe vibration generated during installation can damage the measuring meters, and the normal use of products is influenced.
