Problems solved by technology

[0003] like figure 1 In the prior art shown, before the traditional intelligent pressure gauge is used, due to the different installation positions and angles, the main body of the gauge is not installed horizontally, it is inconvenient for the operator to effectively read its value, and it is prone to numerical reading errors, and When faced with a smooth installation surface, the bolt fixing process is cumbersome and it is difficult to recycle the installation plate. At the same time, after a long time of installation, the main body of the instrument is prone to failure and needs to be disassembled for maintenance. It is inconvenient to disassemble the entire smart instrument down

[0036] see Image 6 As shown, the above-mentioned installation mechanism 7 includes a mounting seat 703 fixedly connected to the outer wall of the instrument body 8, and the top of the mounting seat 703 is provided with a mounting groove for placing the second fixing pin 604, and the second fixing pin 604 is placed through the mounting groove, which is convenient Cooperate with the semi-circular ring 704 to engage and fix the second fixed pin 604. The inside of the mounting seat 703 is provided with a transmission groove 706, and the interior of the transmission groove 706 is slidably provided with a semi-circular ring 704 for fixing the second fixed pin 604. The semi-circular The outer wall of the ring 704 is fixedly equipped with several tooth segments, and one side of the mounting seat 703 is provided with a rotating groove 701, which communicates with the transmission groove 706, and the spur gear 702 is connected to the rotating groove 701 through a latch in rotation, and ...

Embodiment 3

[0039] see Figure 7 and Figure 8 As shown, the above-mentioned adjustment mechanism 4 includes a housing 403 fixedly connected to the front of the mounting plate 2, an air suction pipe 402 is arranged in the middle of the cavity of the housing 403, and both ends of the air suction pipe 402 run through the housing 403. A spherical plug 401 is provided inside, and the two sides of the spherical plug 401 are symmetrically provided with ventilation grooves. The middle part of the spherical plug 401 is fixedly connected with a rotating shaft 404, and one end of the rotating shaft 404 moves through the suction pipe 402 and the casing 403 and is fixedly installed with an adjusting button. The angle of the spherical plug 401 is controlled by turning the adjusting knob, so that the ventilation groove communicates with the suction pipe 402 , so that external air enters into the suction pipe 402 conveniently.

Abstract

The invention relates to an intelligent pressure instrument with an automatic deviation correction function, which comprises a mounting plate and an instrument main body, and is characterized in that a deviation correction mechanism is arranged on the front surface of the mounting plate, the deviation correction mechanism comprises a first frame, the first frame is fixedly connected with the mounting plate through two supporting rods, and a second frame is arranged in the middle of the first frame and is fixedly connected with the mounting plate through two supporting rods; the outer walls of the two sides of the second frame are rotationally connected with the inner wall of the first frame through first fixing pins, the instrument body is located in the middle of the second frame, and limiting plates are symmetrically installed on frame bodies of the other two sides of the second frame. The sides, facing the instrument body, of the two limiting plates are movably connected with the instrument body through second fixing pins, the first frame and the second frame are matched with the first fixing pins and the second fixing pins, the deviation angle of the instrument body is reduced, an operator can conveniently observe numerical values displayed on the instrument body, and the working efficiency is improved. The speed and the accuracy of observing and detecting numerical values are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent pressure instruments, in particular to an intelligent pressure instrument with automatic deviation correction and calibration functions. Background technique [0002] Pressure gauges include ordinary pressure gauges and digital pressure gauges. Due to their high precision, digital pressure gauges are widely used in the fields of pressure measurement and instrument calibration. The main module is a pressure sensor, which is used to detect liquid, gas or steam in pipelines and containers. Pressure, due to the different detected media, the modules required for pressure acquisition are also different. [0003] like figure 1 In the prior art shown, before the traditional intelligent pressure gauge is used, due to the different installation positions and angles, the main body of the gauge is not installed horizontally, it is inconvenient for the operator to effectively read its value, and it is pro...
