Problems solved by technology

[0003] When the current pressure gauge detects pressure, its range is generally not adjustable. As a result, when detecting high pressure, only a pressure gauge with a large range can be replaced, which is not convenient for detection operation. At the same time, the value after detection cannot be fixedly displayed. When the point is reached, the pointer on it will return to its original position, which will cause inconvenient data recording, and the current pressure detection gauge generally does not have a pressure relief port, so that during the detection process, if the inner spring tube cracks, it will be damaged under high pressure. Under the action, it is easy to cause the glass of the pressure gauge to break, and there is a certain safety hazard

Abstract

The pressure gauge comprises a gauge shell, a pointer cavity is fixedly formed in the right side face of the gauge shell, a spring tube cavity with an upward opening is formed in the gauge shell, a dial plate is fixed to the inner wall of the spring tube cavity, and a pressure indicating assembly used for fixing the pressure value is arranged in the dial plate. A measuring range adjusting assembly used for adjusting the pressure detection measuring range is arranged in the lower end wall of the spring pipe cavity. The compression amount of the rack spring is adjusted by rotating the lead screw, so that the measuring range of the pressure gauge is changed by the deformation resistance of the spring tube, pressure values of different magnitudes can be measured, the applicability of the pressure gauge is improved, and meanwhile, by means of one-way rotation of the second one-way bearing and the limiting effect of the ratchet wheel, the measurement precision is improved. The pointer can be kept static after measurement is finished, an operator can record data conveniently, pressure can be released outwards through the pressure relief cavity when the pressure in a spring pipe cavity is too large due to leakage of the spring pipe, and the use safety of the device is improved.

Description

technical field [0001] The invention relates to the related technical field of pressure gauges, in particular to a pressure gauge with an adjustable measuring range. Background technique [0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. [0003] When the current pressure gauge detects pressure, its range is generally not adjustable. As a result, when detecting high pressure, only a pressure gauge with a large range can only be replaced, which is not convenient for detection operation. At the same time, the value after detection cannot be fixedly displayed. point, the pointer on it will return to its original position, which makes it inconvenient to record data, and the current pressure testing gauge generally does not have a pressure relief port, so that during the testing pr...
