Description

Technical Field

[0001] The utility model relates to the technical field of detection pump cavity detection sensors, in particular to a detection pump cavity detection sensor which is easy to install. Background Art

[0002] A pump is a machine that transports fluid or pressurizes fluid. Existing detection sensors have complex structures and high production costs. Before using the detection sensor, it needs to be calibrated to improve the accuracy of pump detection. When testing the pump cavity, the detection sensor needs to be well fixed to prevent it from falling during the inspection, which will affect the inspection data.

[0003] In the prior art, a Chinese patent document with publication number CN110285915A is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a negative pressure sensor with good stability for vacuum pump detection, comprising a housing, a strain gauge and a circuit assembly, the strain gauge and the circuit assembly are electrically connected through the lead wire inside the strain gauge, a negative pressure bin is fixedly connected to the top of the housing, and a sealing tube is provided on the lower side of the housing near the negative pressure bin, a sealing ring is fixedly connected between the sealing tube and the inner wall of the housing, and a piston rod is slidably connected to the inside of the sealing tube. The present invention relates to the field of vacuum pump detection technology.

[0004] In order to solve the problem that the detection sensor is prone to falling due to poor fixation during pump cavity detection, thus affecting the inspection data, the existing technology adopts a fixed component method to deal with it. However, the adhesive tape used for fixing is prone to fall off due to gravity when it is vertically fixed, which leads to the problem that the adhesive fixing strength is limited and some adhesive may remain after removal, affecting the use of the pump body. Utility Model Content

[0013] A further improvement of the technical solution of the utility model is that: the spring is fixedly mounted on the surface of the mounting ring, the fixing plate is fixedly mounted on one end of the spring, and the connecting groove is arranged on the surface of the fixing plate. By arranging a fixing component, it can be achieved that after the overall detection sensor enters the pump cavity, the fixing plate will move outward under the influence of the spring and contact the inner wall of the cavity, thereby fixing the position and preventing it from falling off during the detection process.

By providing multiple groups of springs, the stability of the fixation can be effectively improved, and the overall length of the spring is shorter and the reaction force generated by the pressure is smaller.

[0016] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0017] The utility model provides a pump cavity detection sensor which is easy to install. By setting a fixing component, after the overall detection sensor enters the pump cavity, the fixing plate will move outwards under the influence of a spring and contact the inner wall of the cavity, thereby fixing the position and preventing it from falling off during the detection process.

[0019] The utility model provides a pump cavity detection sensor which is easy to install. By arranging a damping telescopic rod between a connecting plate and a detection barrel body, damping and limiting can be performed after a fixed plate and a connecting plate contact the pump cavity, so as to prevent vibration during the detection process from causing rebound of the spring due to compression.
