[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Through the above structural design, the sensor device 3 can be safely protected by the structural coordination design of the first shell 1 and the protection mechanism 2, thereby improving the safety of the sensor device 3 when in use.

[0036] Specifically, the protective mechanism 2 includes a second shell 4, a first thread groove 5 is opened at the upper end of the second shell 4, a second thread groove 15 is opened inside the lower end of the first shell 1 and at a position corresponding to the first thread groove 5, the first shell 1 is threadedly connected to the first thread groove 5 through the second thread groove 15, first slots are opened on both sides of the inside of the second shell 4, the two first slots are symmetrically arranged, and a clamping mechanism 8 is arranged inside the first slot.

[0037] Through the above-mentioned structural design, when the sensor device 3 needs to be taken out from the inside of the second shell 4, the second shell 4 can be held, and the first shell 1 at the upper end of the second shell 4 can be rotated. When the first shell 1 is rotated, the first shell 1 drives the second thread groove 15 and the first thread groove 5 to rotate and separate. After the second thread groove 15 is separated from the first thread groove 5, the first shell 1 and the second shell 4 are separated, and then the sensor device 3 can be taken out from the inside of the second shell 4.

[0038] Specifically, the clamping mechanism 8 includes an electric telescopic rod 9 , which is fixed inside the first slot. The telescopic end of the electric telescopic rod 9 extends to the inside of the second housing 4 and is fixedly connected to a connecting plate 10 .

[0039] Specifically, the clamping mechanism 8 also includes a clamping plate 11, which is located at a side of the connecting plate 10 away from the electric telescopic rod 9 and corresponds to the connecting plate 10, wherein in order to guide the movement of the clamping plate 11, both ends of the clamping plate 11 close to the connecting plate 10 are fixedly connected with round rods 12, wherein in order to limit the movement of the round rod 12, one end of the round rod 12 away from the clamping plate 11 passes through the connecting plate 10 and extends to the side of the connecting plate 10 away from the clamping plate 11 and is fixedly connected to a limiting block 14, and a second spring 13 is fixedly connected to the middle position of the clamping plate 11 close to the side of the connecting plate 10, and one end of the second spring 13 away from the clamping plate 11 is fixedly connected to the connecting plate 10.

[0040] Through the above-mentioned mechanism design, it can be known that when the sensing device 3 is placed in the middle position inside the second shell 4, the electric telescopic rod 9 can be started, and then the two electric telescopic rods 9 can be started, and the two electric telescopic rods 9 drive the two clamping plates 11 to approach the two sides of the sensing device 3. When the clamping plate 11 is in contact with one side of the sensing device 3, the electric telescopic rod 9 squeezes the connecting plate 10, and then the connecting plate 10 squeezes the second spring 13. The second spring 13 transmits the squeezing force to the clamping plate 11, and the sensing device 3 is clamped and fixed by the two clamping plates 11.

[0041] Specifically, the sensing device 3 includes a detection mechanism 18, which is located inside the second shell 4.

A sensing hole is provided in the middle of the upper end of the connecting rod 19. A fifth slot 16 is provided at the upper end of the first shell 1. The upper end of the connecting rod 19 extends from the position of the fifth slot 16 to the outer side of the upper end of the first shell 1. Second slots are provided on both sides of the fifth slot 16 and at positions corresponding to the peripheral sides of the detection mechanism 18. A limiting mechanism 17 is provided inside the second slot.

[0042] Through the above structural design, it can be known that the detection mechanism 18 can be connected to the engine through the connecting rod 19, and the oil of the engine can flow into the interior of the detection mechanism 18 through the sound sensing hole through the sensitive hole opened on the connecting rod 19. The oil pressure is detected by the detection mechanism 18, and the detected data is transmitted through the transmission mechanism 23.

[0043] Embodiment 2:

[0044] The oil pressure sensor protection housing provided in Example 1 is further optimized. Specifically, Figure 5 , Figure 6 As shown, the limiting mechanism 17 includes a first spring 6, which is located inside the second slot, one end of the first spring 6 is fixedly connected to the inside of the second slot, the other end of the first spring 6 is fixedly connected to a plug-in block 21, the plug-in block 21 is slidably connected to the second slot, a plug-in slot 20 is provided at a position corresponding to the plug-in block 21 of the detection mechanism 18, the plug-in block 21 is plug-connected to the plug-in slot 20, both sides of the plug-in block 21 at one end inside the second slot are fixedly connected to sliders 22, and both sides of the inner wall of the second slot are provided with third slots corresponding to the sliders 22, and the sliders 22 are slidably connected to the third slot.

[0045] Through the above structural design, it can be known that when the connecting rod 19 passes through the position of the fifth slot 16, the detection mechanism 18 squeezes the plug-in block 21, and after the plug-in block 21 is squeezed, the plug-in block 21 slides toward the inside of the second slot. When the plug-in block 21 slides toward the inside of the second slot, the plug-in block 21 squeezes the first spring 6, and then the first spring 6 stores the squeezing force. When the plug-in slot 20 on the detection mechanism 18 moves to a position corresponding to the plug-in block 21, the first spring 6 releases the stored force to push the plug-in block 21 out, and then the pushed-out plug-in block 21 is plugged and connected with the plug-in slot 20 on the detection mechanism 18, and then the plug-in block 21 and the plug-in slot 20 are plugged together to prevent the detection mechanism 18 from rotating inside the sensing device 3.
