The invention discloses a vacuum pressure gauge. The vacuum pressure gauge comprises a pressure gauge main body. A gauge cover main body is movably installed on a front surface of the pressure gauge main body. The right sides of the pressure gauge main body and the gauge cover main body are fixedly connected to a containing block and a first connection block . A fixing device is arranged inside the containing block. The fixing device comprises a bearing block which is movably installed inside the containing block. The back of the first connection block is fixedly connected to a second connection block which is arranged on the right side of the bearing block. The rear end of the second connection block is movably connected to the inside of the containing block. A limiting block and a transmission rod are fixedly connected to the right side of the bearing side. According to the vacuum pressure gauge, the gauge cover can be fixed through the fixing device when people do not need to check the pressure gauge, the gauge cover does not automatically open after closing, and thus the pressure gauge can be effectively protected. The vacuum pressure gauge is simple in structure, easy to operate, provides convenience to people opening and closing the gauge cover and makes usage easy.
Description
technical field [0001] The invention relates to the technical field of vacuum pressure gauges, in particular to a vacuum pressure gauge. Background technique [0002] The vacuum pressure gauge is based on atmospheric pressure and is used to measure instruments that are less than atmospheric pressure. The vacuum pressure gauge is suitable for measuring the vacuum pressure of liquids and gases that have no explosion, no crystallization, no solidification, and no corrosion to copper and copper alloys. [0003] In order to protect the transparent case of the pressure gauge, people install a cover on the pressure gauge for protection. In order to facilitate people to open the cover, there is no fixed structure between the cover and the pressure gauge. Generally, the cover is set to open up and down, but when When the space is limited, it needs to be opened left and right, and the cover of the left and right opening method is easy to open automatically after closing, resulting in ...
