Description

Technical Field

[0001] The utility model relates to the technical field of sensor plastic shells, in particular to a sensor plastic shell which is convenient to fix. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The existence and development of sensors have given objects senses such as touch, taste and smell, making objects come alive. Sensors are an extension of human five senses. Sensors have the characteristics of miniaturization, digitization, intelligence, multi-function, systematization and networking. They are the primary link in realizing automatic detection and automatic control. The plastic shell of the sensor is mostly placed directly on the desktop for use during use.

[0003] However, some existing plastic housings of sensors have poor stability during placement and are not easy to fix. Since the volume of the plastic housing of the sensor is too small and the weight is relatively light, when the plastic housing of the sensor is accidentally touched, the plastic housing of the sensor is likely to fall off the desktop and break, causing the parts inside the plastic housing of the sensor to break, thereby increasing the cost of maintenance and bringing inconvenience to users. To this end, we propose a plastic housing of the sensor that is easy to fix to solve the above problem. Utility Model Content

[0006] Further preferably, four vertical rods are fixedly connected to the bottom of the horizontal plate, and the bottom ends of the vertical rods extend into the vertical tubes and are fixedly connected to pistons.

[0007] Further preferably, the vertical tube is slidably sleeved on the outer side of the corresponding piston, and two round rods are fixedly connected to the bottom inner wall of the connecting box.

[0010] Further preferably, the cross bar is slidably sleeved on the outside of the L-shaped bar, a rotating rod is fixedly connected to the right side of the connecting box, and a gear is fixedly sleeved on the outside of the rotating rod.

[0011] Further preferably, the gear is meshed with the outer gear ring, the right end of the rotating rod is fixedly connected with a knob, and the top and left side of the sensor housing are both connected and fixed with an interface tube.

[0012] Compared with the prior art, the utility model has the following beneficial effects: when the knob is turned, the outer gear ring rotates to drive the circular tube to rotate, and the circular tube drives the vertical block to move through the screw to squeeze the connecting rod, and the horizontal plate compresses the spring, and the horizontal plate drives the piston to move through the vertical rod to discharge the gas in the vertical tube through the suction cup, and the suction cup is brought into contact with the desktop, and the knob is turned, and the spring drives the piston to suck the gas in the vertical tube to generate negative pressure, so that the plastic shell of the sensor has high stability during placement and is easy to fix.
