Differential pressure gauge fixing and mounting structure

The utility model relates to a differential pressure gauge fixing and installing structure, which comprises an installing plate and a fixing mechanism, a cover body and a cover plate connected with the cover body are arranged on the installing plate, the cover plate has a first state in which an accommodating cavity is enclosed with the cover body, the cover plate also has a second state in which the accommodating cavity is opened to form an opening, and when the cover plate is in the first state, the cover plate is fixed on the fixing mechanism. When the cover plate is in the first state, a meter head of the differential pressure meter can be placed in the containing cavity, when the cover plate is in the second state, the meter head of the differential pressure meter can move out of/into the containing cavity through the opening, at least one fixing mechanism is slidably arranged on the mounting plate, a clamping space is formed between the fixing mechanism and the mounting plate, and a meter body of the di
