Detailed implementation manners

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 is the schematic structural diagram of a preferred embodiment of the combined oil fluid sensor provided by the present utility model Figure 2 is Figure 1 Schematic structural diagram of the disassembly and assembly component shown Figure 3 is Figure 1 Schematic structural connection diagram of the protective shell and the outer shell shown Figure 4 is Figure 3 Enlarged schematic structural diagram of the location A shown Figure 5 is Figure 1 Enlarged schematic structural diagram of the location B shown. A combined oil fluid sensor includes an outer shell 1, and a sensor body 2 is arranged inside the outer shell 1

[0024] Disassembly and assembly component 3 is arranged on the outside of the sensor body 2. The disassembly and assembly component 3 includes a positioning groove 301, a moving rod 302, a positioning ring 303, a first clamping plate 304, and a protective shell 305. A positioning groove 301 is opened inside the sensor body 2. A moving rod 302 is slidably connected inside the sensor body 2. A positioning ring 303 is slidably connected inside the positioning groove 301. A first clamping plate 304 and a second clamping plate 12 are respectively arranged inside the outer shell 1. A protective shell 305 is arranged on the outside of the sensor body 2.

[0025] In the specific implementation process, as Figure 2 and Figure 3 shown, a first sealing ring 4 is arranged at the bottom of the outer shell 1. A first clamping block 5 is fixedly connected to the outside of the positioning ring 303.

[0026] A groove 6 is opened inside the sensor body 2. A first spring 7 is sleeved on the outside of the moving rod 302. One end of the first spring 7 is welded to the outside of the moving rod 302.

[0027] A sealing groove 8 is opened inside the sensor body 2. The inner wall of the sealing groove 8 is slidably connected to the outside of the first sealing ring 4.

[0028] A slot 9 is opened inside the protective shell 305. A second sealing ring 10 is arranged inside the slot 9. The outside of the second sealing ring 10 is slidably connected to the inside of the slot 9.

[0029] It should be noted that when the staff needs to overhaul and replace the internal components of the sensor body 2, first, by pulling the pressing plate 16, the second clamping block 17 is disengaged from the inside of the clamping groove 18. Then, the first clamping plate 304 and the second clamping plate 12 are pushed. When the first clamping plate 304 and the second clamping plate 12 move, the second spring 11 on one side of each of them can be stretched, so that the rotating ball 14 is disengaged from the inside of the sensor body 2. Then, the staff pulls the moving rod 302. When the moving rod 302 moves, the first spring 7 can be compressed, and further the moving rod 302 can move away from the groove 6. After the moving rod 302 moves to the specified position, the staff rotates the outer shell 1. When the outer shell 1 rotates, it can drive the positioning ring 303 to move, and thus drive the first clamping block 5 on the outside of the positioning ring 303 to move. When the positioning ring 303 moves to the specified position, the first clamping block 5 can be disengaged from the inside of the sensor body 2. Then, the outer shell 1 is pulled, and further the outer shell 1 can be disengaged from the outside of the sensor body 2, so as to facilitate the staff to overhaul and replace the internal components of the sensor body 2.

[0030] Refer to Figure 3 、 Figure 4 and Figure 5As shown, a second spring 11 is welded to the inner wall of the housing 1, and one end of the second spring 11 is welded to one side of the second clamping plate 12.

[0031] One side of the second clamping plate 12 is fixedly connected to a connecting rod 13, and a rotating ball 14 is rotatably connected inside the connecting rod 13.

[0032] A third spring 15 is welded to the outside of the sensor body 2, one end of the third spring 15 is welded to a pressing plate 16, a second clamping block 17 is fixedly connected to the rear surface of the pressing plate 16, and a clamping groove 18 that is slidably engaged with the second clamping block 17 is formed inside the housing 1.

[0033] It should be noted that: when the staff disassembles and assembles the sensor body 2 and the housing 1, first, the pressing plate 16 needs to be pulled, so that the pressing plate 16 rotates on the outside of the sensor body 2. When the pressing plate 16 moves, it can drive the third spring 15 to elongate, so that the second clamping block 17 can be disengaged from the inside of the clamping groove 18. Then, the staff can pull the moving rod 302 to adjust the position of the moving rod 302. At the same time, under the elastic force of the rotating ball 14 and the second spring 11, the outside of the rotating ball 14 can be closely attached to the inner wall of the sensor body 2, so that the sensor body 2 can be repositioned through the rotating ball 14.

[0034] The working principle of a combined oil fluid sensor provided by the present utility model is as follows:

[0035] When the staff conducts long-term detection of the oil fluid through the sensor body 2 of this device, it is necessary to disassemble and assemble it regularly, and overhaul and replace the components inside the sensor body 2. First, the staff pulls the pressing plate 16, causing the pressing plate 16 to rotate outside the sensor body 2, thereby causing the third spring 15 to elongate. After the pressing plate 16 moves to the specified position, the second clamping block 17 can be disengaged from the inside of the clamping groove 18. After the second clamping block 17 reaches the specified position, then the first clamping plate 304 and the second clamping plate 12 are pushed. When the first clamping plate 304 and the second clamping plate 12 move, the second spring 11 on one side of each of them can be stretched, so that the rotating ball 14 is disengaged from the inside of the sensor body 2, and thus the sensor body 2 is initially disengaged from the housing 1. Then the staff pulls the moving rod 302. When the moving rod 302 moves, it can drive the first spring to move, and then the first spring 7 is compressed, so that the moving rod 302 can be disengaged from the inside of the groove 6. After the moving rod 302 moves to the specified position, the staff rotates the housing 1. When the housing 1 rotates, it can drive the positioning ring 303 to move, and thus can drive the first clamping block 5 outside the positioning ring 303 to move. When the positioning ring 303 moves to the specified position, the first clamping block 5 can be disengaged from the inside of the sensor body 2. Then the housing 1 is pulled, and thus the housing 1 can be disengaged from the outside of the sensor body 2, so that the housing 1 is completely disengaged from the sensor body 2, which is convenient for the staff to overhaul and replace the components of this device.
