[0027] Please pay attention to Figures 1 to 6 A sensor housing comprises a pad 1, a detachable protective housing 2 is arranged at the upper end of the pad 1, a plurality of detachable protective covers 3 are arranged at the lower end of the pad 1, bar-shaped through grooves 11 are symmetrically arranged on the pad 1, a connecting seat 21 is symmetrically arranged on the inner wall of the protective housing 2, the connecting seat 21 is provided with a through hole 211, a movable clamping plate 22 is arranged on the connecting seat 21, the clamping plate 22 is provided with a rotating shaft 221 inserted into the through hole 211, and a torsion spring 222 is arranged between the rotating shaft 221 and the through hole 211.

[0028] Specifically, the protective shell 2 can play the function of protecting the sensor, and the protective cover 3 can play the function of protecting the sensor pin. Through the connecting seat 21, through hole 211, clamping plate 22, rotating shaft 221, torsion spring 222 and other structures designed in the protective shell 2, the torsion spring 222 can make the clamping plate 22 always maintain an eight-shaped shape. When a sensor is installed in the protective shell 2, the clamping plate 22 is squeezed and begins to approach the inner wall of the protective shell 2. When the sensor is installed in place, the torsion spring 222 can apply torque to the clamping plate 22, so that the clamping plate 22 clamps the sensor to prevent the sensor from loosening or falling.

[0029] Please pay attention to Figure 5 The lower end surface of the pad 1 is symmetrically provided with an inner ring 12, and the symmetrically provided inner ring 12 is arranged below the strip-shaped through groove 11. The protective cover 3 is detachably connected to the inner ring 12 and is interference fit with the inner ring 12. The design of the protective cover 3 can cover the pin pins of the sensor to prevent the pin pins from being squeezed and damaged.

[0030] Please pay attention to Figure 2 , Figure 6 The upper end surface of the pad 1 is symmetrically provided with spring pieces 13, and the symmetrically provided spring pieces 13 are installed on the outside of the symmetrically provided strip-shaped through grooves 11. The ends of the symmetrically provided spring pieces 13 that are away from each other are provided with clamps 131, and the design of the clamps 131 on the spring pieces 13 can clamp the protective shell 2.

[0031] The front and rear walls of the inner side of the protection shell 2 are symmetrically provided with inwardly recessed card slots 23 . The card slots 23 are designed to be connected to the card head 131 , so as to achieve the function of installing the protection shell 2 .

[0032] The clamping head 131 and the clamping slot 23 are designed to be trapezoidal, and this design can facilitate the disassembly and assembly of the protective shell 2.

[0033] Please pay attention to Figure 1 The front and rear walls of the protective shell 2 are symmetrically provided with anti-slip stripes 24. The design of the anti-slip stripes 24 enables the protective shell 2 to be stably grasped when the protective shell 2 is disassembled.

[0034] A heat dissipation slot 25 is disposed on the top of the protective housing 2. The heat dissipation slot 25 is designed to remove the heat generated when the sensor is working, thereby preventing the sensor from being damaged due to heat accumulation.

[0035] Please pay attention to Figure 4 The front and rear walls of the backing plate 1 are symmetrically provided with gaskets 14, and the gaskets 14 are provided with through holes 141. The gaskets 14 and the through holes 141 are designed to allow screws to be driven in, thereby installing the backing plate 1.

[0036] The specific operation method of the utility model is as follows: when in use, the sensor is first installed in the protective shell 2. When installing the sensor in the protective shell 2, the clamping plate 22 is first squeezed by the sensor and begins to approach the inner wall of the protective shell 2. At the same time, the torsion spring 222 begins to tighten as the clamping plate 22 rotates. When the sensor is installed in place, the tightened torsion spring 222 can apply torsion to the clamping plate 22, so that the clamping plate 22 clamps the sensor to prevent the sensor from loosening or falling off. At this time, the sensor is installed in the protective shell 2.

[0037] After the installation is completed, the staff's index finger and thumb are pinched on the anti-slip stripes 24 on the two walls of the protective shell 2 respectively, and then the protective shell 2 is aligned with the pad 1 and installed towards the pad 1. (During installation: pay attention to the pin of the sensor, and ensure that the pin of the sensor can pass through the strip groove 11 on the pad 1 normally). As the protective shell 2 is installed, the clamping head 131 will first contact the inner wall of the protective shell 2. The clamping head 131 after being squeezed will cause the spring piece 13 to deform, until the protective shell 2 and the pad 1 are fully snapped into place, the deformed spring piece 13 will return to a vertical state, and synchronously, the clamping head 131 will also be stuck in the card slot 23 on the inner side of the protective shell 2. At this time, the snap-fit ​​installation of the pad 1 and the protective shell 2 is completed. After the installation is completed, the protective cover 3 is put on the pin of the sensor and plugged into the inner ring 12. The installation of the sensor is completed in a century.

[0038] When it is installed and needs to be used, first remove the protective strip and insert the pin of the sensor into the corresponding interface. After installation, use bolts or screws to pass through the through holes 141 of the gasket 14 and fix it. The installation of the sensor is completed. After installation, it can be put into normal use. When in use, the heat dissipated by the sensor can be discharged in time through the heat dissipation slot 25 to avoid damage to the sensor due to excessive temperature.

[0039] When the sensor is damaged, the protective shell 2 can be grasped and pulled away from the backing plate 1 to remove the sensor, and then the sensor can be replaced with a new one for use.

[0040] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
