Technical Field

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressure higher than the ambient pressure.

[0003] A pressure gauge consists of a pressure-guiding element, a gear transmission, an indicator, and a housing. Pressure gauges are extremely common, found in nearly all industrial processes and scientific research fields. They can be found in heating networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Mechanical pressure gauges are particularly popular in industrial process control and technical measurement due to their high mechanical strength and ease of production, as well as the elasticity of their sensitive elements.

[0004] In the process of shipbuilding, a large number of pressure gauges are usually used. When calibrating the pressure gauges, the existing pressure gauge calibration console can only calibrate two pressure gauges of the same specifications at the same time. For a large number of pressure gauges that need to be calibrated, it is impossible to perform fast and efficient metrological calibration while ensuring accuracy.

[0005] In view of this, the present technical solution proposes an auxiliary tooling for pressure gauge metrological calibration, so as to better solve the above-mentioned problems. Utility Model Content

[0007] A group of pipe support platforms are fixed with fixed rods at the front and back of the top, and connecting rods are fixed between the fixed rods. A movable sleeve is provided on the connecting rod, and an auxiliary magnifying glass for magnifying the numbers on the dial of the pressure gauge body is installed above the movable sleeve through the support rod.

[0008] In a preferred embodiment, the interior of the pipe support platform is provided with mounting grooves adapted for use with the annular circulation pipe at the front and rear ends, and the annular circulation pipe is arranged in the mounting grooves.

[0009] In a preferred embodiment, the upper portion of the detection pipe connection port is adapted to the installation location of the pressure gauge body, and the detection pipe connection port and the pressure gauge body are detachably installed.

[0010] In a preferred embodiment, the boosting device is electrically connected to an external controller and a power supply.

[0011] In a preferred embodiment, the fixing rod and the connecting rod can be fixedly and detachably installed.

[0012] In a preferred embodiment, the connecting rod is adapted to the movable sleeve, and the movable sleeve is a U-shaped structure.

[0013] In a preferred embodiment, the observation auxiliary magnifying glass is arranged opposite to the pressure gauge body, and the diameter of the observation auxiliary magnifying glass is larger than the dial diameter of the pressure gauge body.

[0014] In summary, due to the adoption of the above-mentioned technical solution, the beneficial effects of the utility model are: it is convenient to better calibrate multiple pressure gauge bodies at the same time, and the auxiliary magnifying glass can be moved to facilitate observation of the numbers on the dial of the pressure gauge body at different positions, so as to better understand the measurement status of the pressure gauge body.

[0015] 1. In the present invention, by installing the pressure gauge body on the detection pipe connection port, the booster device, the connecting pipe and the communicating pipe cooperate to transport gas to the interior of the annular circulation pipe, so that the gas applies pressure to the pressure gauge body through the detection pipe connection port, and the pressure gauge body can be measured and calibrated.

[0016] 2. In the present invention, by moving the auxiliary observation magnifying glass, the support rod drives the movable sleeve to move on the connecting rod. When the auxiliary observation magnifying glass is moved to the front of one of the pressure gauge bodies, the numbers on the dial of the pressure gauge body can be better observed, and the measurement status of the pressure gauge body can be better understood.
