[0026] Reference Figure 1-Figure 3 The utility model provides an embodiment of an oil injection vacuum back-suction device, including an oil pipeline 1 and a mounting seat 8. A connecting pipe 2 is slidably connected to the oil pipeline 1, a connecting plate 4 is fixedly connected to the connecting pipe 2, a connecting rod 5 is hinged on the connecting plate 4, two ends of the connecting rod 5 are fixedly connected to a spring 6, one end of the spring 6 away from the connecting rod 5 is fixedly connected to the connecting pipe 2, the connecting rod 5 is slidably connected to the oil pipeline 1, a square opening 7 is provided on the oil pipeline 1, the connecting rod 5 slides in the square opening 7, the connecting rod 5 passes through the square opening 7, an oil filling head 3 is provided on the end of the connecting pipe 2 away from the oil pipeline 1, by providing a connecting plate 4, a connecting rod 5 and a spring 6 on the connecting pipe 2, the connecting pipe 2 and the oil pipeline 1 can be quickly installed, and the oil pipeline 1 and the connecting pipe 2 can also be quickly disassembled and separated. Therefore, through such a setting, it is convenient for the staff to replace and clean the oil filling head 3 on the connecting pipe 2, saving time and effort.

[0027] A vacuum pump 9 is fixedly connected to the mounting seat 8, and a gas injection port 1 10 is provided on the vacuum pump 9, and a gas injection port 2 11 is provided on the vacuum pump 9. A connecting pipe 2 13 is fixedly connected to the end of the vacuum pump 9 away from the gas injection port 2 11, and the connecting pipe 2 13 is fixedly connected to the oil pipeline 1, and an oil outlet pipe 12 is fixedly connected to the connecting pipe 2 13, and an oil storage tank 14 is fixedly connected to the end of the oil outlet pipe 12 away from the connecting pipe 2 13, and the oil storage tank 14 is fixedly connected to the mounting seat 8, and an oil injection port 15 is provided on the oil storage tank 14, and a connecting pipe 12 is fixedly connected to the oil pipeline 1. There is a third gas injection port 16, a fourth gas injection port 17 is provided on the oil pipeline 1, and a valve 18 is provided on the oil pipeline 1. The valve 18 is located at the front end of the fourth gas injection port 17. The oil pipeline 1 is fitted with the oil filling head 3. By arranging the vacuum pump 9, the first gas injection port 10, the second gas injection port 11, the third gas injection port 16, and the fourth gas injection port 17, when the vacuum pump 9 draws a vacuum into the oil pipeline 1 and the interior of the oil pipeline 1, the oil extraction end can draw the residual oil in the oil pipeline 1 back into the oil storage tank 14. Therefore, such an arrangement can prevent the waste of oil and save costs.

[0028] Working principle: First, when it is necessary to supply oil to an object, air can be supplied to the air injection port three 16 to open the valve 18, and then the oil will come out of the oil storage tank 14 and enter the oil outlet pipe 12, and then enter the oil pipeline 1 through the connecting pipe 2 13, and finally reach the oil filling head 3 to be injected into the object. When the oil is fully supplied, air can be supplied to the air injection port four 17 to close the valve 18. Then, when it is necessary to suck back the residual oil in the oil pipeline 1, air can be supplied to the air injection port one 10 to start the vacuum pump 9, and the internal oil extraction end can be moved to establish a vacuum inside the device. Then, in the oil pipeline 1, the residual oil will flow from the oil pipeline 1 into the connecting pipe two 13. After that, when air is supplied to the air injection port two 11, the driving end on the vacuum pump 9 is reset, pushing the oil extraction end to establish Positive pressure, and then the oil will flow from the connecting pipe 2 13 into the oil outlet pipe 12, and finally reach the oil storage tank 14. When the oil filling head 3 needs to be replaced, the connecting pipe 1 2 can be pulled backward to make the connecting rod 5 rotate outward and slide along the square opening 7, while squeezing the spring 6 at one end, so that the connecting rod 5 can slide out of the square opening 7, so that the connecting pipe 1 2 can be removed, and then the new connecting pipe 1 2 can be pushed inward along the oil pipeline 1, so that the connecting pipe 1 2 slides on the oil pipeline 1, and the connecting rod 5 slides along the oil pipeline 1 while squeezing a group of springs 6. When sliding to the square opening 7, the spring 6 will bounce the connecting rod 5 into the square opening 7, so that the connecting pipe 1 2 can be installed on the oil pipeline 1, and the replacement of the oil filling head 3 is completed.
