Description

Technical Field

[0001] The utility model relates to the field of sensors, in particular to a sensor which is easy to repair. Background Art

[0002] A sensor is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules. There are many types of sensors, among which the temperature and humidity sensor is a device or device that can convert temperature and humidity into electrical signals that are easy to measure and process. It is equipped with humidity and heat sensitive elements and can be used to measure temperature and humidity. Temperature and humidity sensors mostly use detection probes as temperature measuring elements to collect temperature and humidity signals. After a series of circuit processing, they are converted into current signals or voltage signals that are linearly related to temperature and humidity for output. They can also be directly output through the main control chip for interface output.

[0003] The temperature and humidity sensors on the market include a sensor body and a mounting shell arranged on the outside of the sensor body. The mounting shell is arranged on the outside of the sensor body to protect the circuit devices in the sensor body. However, most of the existing ultrasonic sensors are one-piece structures, and the mounting cover is fixed to the mounting shell by bolting. In actual use, once the circuit devices in the sensor body fail and need to be repaired, the maintenance personnel need to use professional tools to remove the multiple bolts used to connect the mounting shell and the mounting cover before they can repair the circuit devices in the sensor body. After the maintenance is completed, the mounting shell and the mounting cover need to be re-installed by bolts. The bolted design makes disassembly and installation more cumbersome, time-consuming and labor-intensive, which increases the difficulty and time cost of maintenance to a certain extent.

[0004] Therefore, it is necessary to provide a new sensor that is easy to repair to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sensor which is easy to repair.

[0006] The sensor provided by the utility model is easy to repair and comprises: a mounting shell and a sensor body fixedly arranged in the mounting shell, a mounting cover is slidably arranged on the mounting shell, a mounting plate is fixedly connected to the bottom of the mounting cover, and the mounting shell is connected to the mounting plate through two limit members;

[0007] The limit member includes a limit rod, and limit blocks are fixedly connected to the side walls on opposite sides of the limit rod. The mounting shell and the mounting plate are respectively provided with a first through hole and a second through hole adapted to the shapes of the limit rod and the two limit blocks. A circular groove is provided on the inner side wall of the second through hole, and the two limit blocks can rotate in the circular groove. A spring for applying thrust to the two limit blocks is fixedly connected to the bottom side of the inner wall of the circular groove, and two limit grooves matching the shapes of the limit rod are provided on the inner side wall of the circular groove.

[0008] Preferably, one end of the limiting rod is fixedly connected with a knob.

[0009] Preferably, both sides of the bottom end of the mounting plate are provided with sliding blocks, and the two sliding blocks slide in two sliding grooves fixedly arranged on both sides of the mounting shell respectively.

[0010] Preferably, a detection probe is fixedly connected to one side of the mounting shell.

[0011] Preferably, a display screen is embedded and mounted on a side of the mounting shell away from the mounting plate.

[0012] Preferably, a plurality of heat dissipation slots are provided on the side wall of the mounting shell.

[0013] Compared with the related art, the sensor provided by the utility model that is easy to repair has the following beneficial effects:

[0014] The utility model provides a sensor that is easy to maintain. When the sensor body needs to be maintained, the limit rod is first pressed inwards, and one end of the limit rod applies pressure to the spring to compress it, and the limit blocks on both sides of the limit rod slide out of the limit groove and fit into the bottom side of the circular groove. At this time, the limit rod is rotated, and the limit block rotates in the circular groove. Since the circular groove is connected to the second through hole, the limit block is stuck in the second through hole after rotating a certain angle, and pops out from the second through hole under the thrust applied by the spring. At this time, the limit rod can be drawn out from the first through hole and the second through hole, and the limit rod does not limit the mounting shell and the mounting cover, so the mounting cover can be slid on the mounting shell. Compared with the traditional method of disassembling bolts, this structure saves time and effort, is convenient for maintenance or maintenance of the sensor body in the mounting shell, and reduces the maintenance difficulty and cost to a certain extent.
