Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor with a protection mechanism. 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. However, existing sensors generally do not have external protection. When hit, the display screen is easily damaged and internal components are prone to failure.

[0003] The existing patent (publication number: CN214887033U) proposes a sensor, including a pressure sleeve, an upper joint that can be connected to an electric pump is arranged on the top of the pressure sleeve, and a lower joint that can be connected to a cable is arranged on the bottom. The interior of the pressure sleeve is divided into a cable channel section and a working section. One end of the cable channel section is located at the top of the pressure sleeve and is connected to the upper joint, and the other end is located at the bottom of the pressure sleeve and is connected to the lower joint. The cable is passed through the cable channel section; a sensitive element and a signal processing unit are arranged in the working section; the signal processing unit is wirelessly connected to a ground micro-control device.

[0004] The above-mentioned sensor adopts a technical solution to solve the structural change inside the sensor body by changing the structure inside the sensor body, thereby achieving the original working mode without changing the original working mode, but meeting the new design of using a cable to pass through the oil pipe hanger into the oil pipe and pass through the hanger to connect with the top of the electric pump unit. The problem with this solution is that although it solves the internal structural change of the sensor and meets the requirement of using a cable to pass through the oil pipe hanger into the oil pipe, since there are no protective components on the outside of the sensor, the sensor is easily affected by external pressure, resulting in damage to the internal structure of the sensor. Therefore, we propose a sensor with a protective mechanism to solve the above problem. Utility Model Content

[0005] The utility model provides a sensor with a protection mechanism, which solves the technical problem that the current sensor has no protection structure.

At this moment, the external force will be buffered by the spring to prevent the sensor body from being squeezed by external force, causing damage to the internal structure.

[0013] Preferably, the size of the mounting groove is the same as the size of the mounting plate.
