[0025] This utility model provides an electronic sensor that is easy to maintain.

[0026] Please see Figure 1 , Figure 3 and Figure 4 The system includes a sensor housing 1, with a protective sleeve 2 slidably connected inside the sensor housing 1. The curvature of the protective sleeve 2 is the same as that of the sensor housing 1. When the protective sleeve 2 slides into the sensor housing 1, it can expose the electrical components inside the sensor housing 1, so that the staff can inspect and repair the internal components of the sensor, reduce the labor intensity of disassembling and installing the housing, and improve maintenance efficiency. The protective sleeve 2 and the sensor housing 1 have good sealing performance and friction, which can protect the internal components of the sensor.

[0027] Please see Figure 2 An internal connecting seat 6 is fixedly installed inside the sensor housing 1. Two iron cores 7 are movably installed inside the internal connecting seat 6. The internal connecting seat 6 facilitates the installation and connection of internal components of the sensor. The sensor housing 1, internal connecting seat 6, iron cores 7, circuit board 8, hub 9 and connecting wire 11 involved in this application are all prior art, and will not be described in detail in this application. The iron cores 7 can be replaced according to different types of sensors, and should be based on actual needs. The inside of the housing is filled with epoxy resin, which serves as a seal and insulation.

[0028] The circuit board 8 is fixedly installed inside the internal connector 6 by bolts. The hub 9 is fixedly connected inside the internal connector 6. The circuit board 8 can be used to install various electrical components and realize the electrical connection between electronic components. The hub 9 can protect the internal circuit of the sensor and avoid messy circuit distribution that affects maintenance work. The hub 9 has good toughness and can be bent to a certain extent without affecting the disassembly and maintenance of other components by the staff.

[0029] Please see Figure 1 and Figure 2 One end of the sensor housing 1 is fixedly connected to a mounting bolt 10, and the other end of the sensor housing 1 is fixedly connected to a connecting wire 11. The mounting bolt 10 facilitates the installation of the electronic sensor in the required position, while the connecting wire 11 facilitates the connection of the sensor to other external electrical equipment, thereby sensing the detection information.

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A drive rod 3 is provided on the outside of the sensor housing 1. A control button 4 is fixedly connected to the outer surface of the drive rod 3. A handle is installed on the surface of the protective cover 2, which is convenient for the staff to pull the protective cover 2. When the staff wants to open the protective cover 2, they first press the control button 4. The force on the control button 4 can drive the drive rod 3 to move closer to the sensor housing 1. The movement of the drive rod 3 can provide power to the locking mechanism 5, so that the locking mechanism 5 can release the limit on the protective cover 2. At this time, the protective cover 2 can be pulled to expose the internal components of the sensor housing 1, which is convenient for subsequent testing and maintenance of the internal components of the sensor.

[0031] Please see Figure 3 , Figure 4 and Figure 5 The sensor housing 1 is equipped with a locking mechanism 5 inside. The locking mechanism 5 can effectively and stably connect the sensor housing 1 and the protective cover 2. The specific number and position of the locking mechanism 5 should be based on actual needs.

[0032] The locking mechanism 5 includes a movable locking plate 501 and a fixed buckle 502. The movable locking plate 501 slides inside the sensor housing 1, and the fixed buckle 502 is fixedly connected to the bottom surface of the protective sleeve 2. The movable locking plate 501 and the fixed buckle 502 are adapted to each other, and their ends have corresponding buckles. When the fixed buckle 502 engages with the movable locking plate 501, the protective sleeve 2 can be stably placed inside the sensor housing 1, thereby protecting the internal components of the sensor housing 1. When the locking plate 501 and the fixing buckle 502 are disengaged, the operator can slide the protective cover 2 into the sensor housing 1 to repair the internal components of the sensor housing 1. Both the movable locking plate 501 and the fixing buckle 502 have a movable arc at their ends. When the protective cover 2 is closed, the fixing buckle 502 will press the movable locking plate 501 to slide. After the fixing buckle 502 moves into place, the movable locking plate 501 will automatically engage with the fixing buckle 502 under the action of the telescopic spring 504.

[0033] The movable plate 501 has two internal sliding connections of support rods 503. Both ends of each support rod 503 are fixedly connected to the sensor housing 1. The support rods 503 provide support and limit the sliding of the movable plate 501, preventing the movable plate 501 from tilting during the sliding process and keeping the movable plate 501 in a vertical state. There is a certain friction between the movable plate 501 and the support rods 503, which can offset the small amplitude of shaking caused by the characteristics of the telescopic spring 504, and ensure the stability of the engagement between the movable plate 501 and the fixed buckle 502.

[0034] Each support rod 503 has a telescopic spring 504 fitted on its outer surface. One end of each telescopic spring 504 is fixedly connected to the sensor housing 1, and the other end of each telescopic spring 504 is fixedly connected to the movable locking plate 501. The telescopic spring 504 has the effect of pulling the movable locking plate 501 to reset, which can keep the movable locking plate 501 and the fixed buckle 502 stably engaged, thereby improving the protection effect of the device on the internal components of the sensor.

[0035] A transmission rod 505 is fixedly connected to the outer surface of the movable plate 501. The transmission rod 505 passes through the sensor housing 1 and is slidably connected to the sensor housing 1. One end of the transmission rod 505 is fixedly connected to the drive rod 3. When the control button 4 is pressed, the drive rod 3 can push the transmission rod 505 to slide inside the sensor housing 1. The sliding of the transmission rod 505 can push the movable plate 501 to slide, thereby disengaging the movable plate 501 from the fixed buckle 502. This makes it convenient for the staff to open the protective cover 2 and repair the internal components of the sensor housing 1. The transmission rod 505 and the sensor housing 1 have strong friction, which can effectively prevent the transmission rod 505 from sliding on its own due to external vibration or other reasons.

[0036] Working principle: When the operator wants to repair the internal components of the sensor, they first press the control button 4. The control button 4 pushes the drive rod 3 closer to the sensor housing 1. The movement of the drive rod 3 causes the transmission rod 505 to slide inside the sensor housing 1. The transmission rod 505 pushes the movable plate 501 to slide on the support rod 503. When the movable plate 501 slides to a certain position, it will disengage from the fixed buckle 502. At this time, the operator pulls the protective cover 2 by the handle to slide the protective cover 2 into the sensor housing 1. At this time, the internal components of the sensor housing 1 will be exposed, making it convenient for the operator to perform component testing. After the repair is completed, the operator pulls the protective cover 2 in the opposite direction by the handle until the fixed buckle 502 engages with the movable plate 501 again, thus completing the installation of the sensor. This greatly improves the efficiency of the operator's repair work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
