The invention discloses a pressure instrument adapter comprising a three-way pipe. The left end of the three-way pipe is connected with a tubing via a flange. The three-way pipe is provided with a fixing device thereon. The fixing device is fixedly connected with the three-way pipe. A cavity is formed at the bottom end of the fixing device. A deceleration motor is mounted at the top end of the middle portion of the cavity. A threaded rod is connected to a driving end of the deceleration motor. A support plate is threadedly connected on the threaded rod. Connecting rods are rotatably connectedwith both ends of the support plate. A sector gear is connected to a far end of each connecting rod away from the support plate. Middle portions of the sector gears are rotatably connected onto the fixing device. Racks are symmetrically and vertically arranged on both ends of the cavity, and the sector gears mesh with the racks. Limiting cavities are formed at both ends of the fixing device. According to the invention, the structure is stable, a pressure gauge is easy to mount and disassemble, and the use of a motor driving method can save a large amount of time and effort of workers, and thepressure instrument adapter is worthy of promotion.
Description
technical field [0001] The invention relates to the technical field of pressure instruments, in particular to a pressure instrument adapter device. Background technique [0002] According to aircraft manufacturing requirements, aircraft fuel and hydraulic system components need to be tested for working pressure. The oil pressure needs to be accurately monitored, and the test pressure is often higher than the normal working pressure. An external hydraulic instrument device is required for real-time pressure control and parameter reading. However, the connection device of the pressure instrument in the prior art has a simple structure and is not strong enough to engage. , resulting in inaccurate data during testing. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the structure of the connection device in the prior art is too simple, which leads to the problem that the clamping is not firm and affects the measurement data,...
