Abstract

The present invention discloses a pressure sensor with a protection rod. The pressure sensor comprises a device body which is a cavity structure, and rotating bolts are both installed at the bottom ends of the outer walls at the two sides of the device body and are fixed with rotating rods. The other ends of the rotating rods penetrate the wall body of the device body and are fixed with winding reels, and the rotating rods extend to the cavity of the device body. Second springs are both fixed at the two sides of the inner wall at the bottom end of the device body, the top ends of the second springs are both fixed with fastening buckles, and the top end of the fastening buckles are fixed with the protection rods. The fastening bolts are both installed at the two sides of the protection rodsrotatably, limiting rods are installed at one sides of the fastening bolts rotatably, fourth springs sleeve the limiting rods, and one ends of the fourth springs are fixed with the fastening bolts. The pressure sensor of the present invention is reasonable in structure design, is simple to operate, when being used, can effectively realize the situation that the protection rods pop up automatically when the pressure is too large, thereby protecting. A protection device is high in sensitivity and good in protection effect.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a pressure sensor with a protective rod. Background technique [0002] At present, with the development of Seiko technology, pressure sensors are used in more and more equipment and many mechanical property testing systems. This kind of sensor has the characteristics of simple structure, low cost and mature test system technology, so it can be widely used. Each finished pressure sensor has a standard range. In the process of applying pressure load, if the load exceeds the range of the pressure sensor, it will cause irreversible deformation of the internal elastic body of the pressure sensor, causing the test system to malfunction, thus affecting the performance of the equipment. Accuracy of work and trials. Due to the easy damage of the pressure sensor, the load applied to the pressure sensor must be strictly controlled during the use of the pressure sensor to ensure t...
