DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-Figure 6 The utility model is further explained as follows: a quantitative oil pumping device comprises an oil storage cylinder 1, a fixed seat 2 is placed on the top of the oil storage cylinder 1, an oil pumping cylinder 3 is fixedly installed on the upper surface of the fixed seat 2, an oil outlet pipe 4 and an oil inlet pipe 5 are symmetrically arranged on the inner bottom wall of the oil pumping cylinder 3, an oil pumping piston 6 is arranged in the oil pumping cylinder 3, a driving chamber 7 is opened in the fixed seat 2, a driving assembly 8 for lifting the oil pumping piston 6 is arranged in the driving chamber 7, the upper end of the driving assembly 8 extends and is arranged in the oil pumping cylinder 3, a scale line 9 is arranged on the outer wall of the oil pumping cylinder 3, a clamping assembly 10 is symmetrically fixedly installed on the circumferential outer wall of the fixed seat 2, and the clamping assembly 10 comprises an adjusting rod 1007, and the adjusting rod 1007 is symmetrically fixedly installed on the circumferential outer wall of the fixed seat 2.

[0023] like Figure 3 and Figure 5As shown, the drive assembly 8 includes a drive motor 801, which is embedded in the inner bottom wall of one end of the drive chamber 7, and an active screw 802 is fixedly installed at the output end of the drive motor 801. One end of the active screw 802 penetrates the drive chamber 7 and extends to the inner top wall of the pumping cylinder 3. A driven screw 803 is rotatably installed at the other end of the drive chamber 7. One end of the driven screw 803 penetrates the drive chamber 7 and extends to the inner top wall of the pumping cylinder 3. The active screw 802 and the driven screw The upper ends of the levers 803 penetrate the pumping piston 6 and are rotatably engaged with the pumping piston 6. The lower ends of the active lead screw 802 and the driven lead screw 803 are respectively provided with a driving sprocket 804 and a driven sprocket 805. The outer surfaces of the active sprocket 804 and the driven sprocket 805 are jointly engaged with a synchronous chain 806. One end of the oil outlet pipe 4 and the oil inlet pipe 5 are both extended along the inside of the fixed seat 2 to be connected to the inner bottom wall of the pumping cylinder 3. One end of the oil outlet pipe 4 is provided with an oil outlet check valve 11 , one end of the oil inlet pipe 5 is provided with an oil inlet check valve 12, the other end of the oil outlet pipe 4 is connected to the inside of the oil storage cylinder 1, and the top of the oil pumping cylinder 3 is fixedly installed with an ash-blocking air inlet net 13, so that when the staff turns on the drive motor 801, the drive motor 801 drives the active screw 802 to rotate, and the driven screw 803 can be moved forward through the rotation of the active screw 802 and the cooperation of the active sprocket 804 and the driven sprocket 805 plus the synchronous chain 806. The oil pumping piston 6 that is rotatably engaged with the active lead screw 802 and the driven lead screw 803 can slide and rise and fall in the oil pumping cylinder 3. The sealing fit between the oil pumping piston 6 and the inner wall of the oil pumping cylinder 3 can increase the negative pressure in the oil pumping cylinder 3. As a result, the oil inlet pipe 5, under the action of the oil inlet check valve 12, draws external oil from the oil inlet pipe 5 into the oil pumping cylinder 3. The oil intake in the oil pumping cylinder 3 can be judged by the scale line 9. The oil pumping cylinder 3 is made of transparent material.

[0024] like Figure 2 , Figure 4 and Figure 6As shown, a synchronous moving block 1001 is slidably installed on the outer surface of one end of the adjusting rod 1007, and linkage ropes 1002 are symmetrically fixedly installed on both sides of the synchronous moving block 1001. A clamping frame 1003 is fixedly installed on one end of the linkage rope 1002. A fixed frame 1004 is sleeved on the outside of one end of the clamping frame 1003. One end of the fixing frame 1004 is fixedly installed on the circumferential outer wall of the fixing seat 2. A rope hole 1005 is opened on the outer wall of one side of the fixing frame 1004. An adjusting spring 1006 is symmetrically fixedly installed on the inner wall of one end of the fixing frame 1004. One end of the adjusting spring 1006 is fixedly connected to one end of the clamping frame 1003 inserted in the fixing frame 1004, so that when the staff places the fixing seat 2 on the upper end of the oil storage cylinder 1, the staff uses both hands to simultaneously pull the symmetrically arranged outer wall of the fixing seat 2 The synchronous moving block 1001 on the adjusting rod 1007 can drive the linkage rope 1002 to simultaneously pull the clamping frame 1003 set at a ninety degree angle to slide in the stable frame. At this time, the adjusting spring 1006 is gradually stretched, and then the staff will fit one end of the clamping frame 1003 with the upper circumferential outer wall of the oil storage cylinder 1, so as to clamp oil storage cylinders 1 of different sizes. Then the staff will connect one end of the oil outlet pipe 4 with the oil storage cylinder 1, and then turn on the power of the driving motor 801. Then, with the cooperation of the active screw 802, the driven screw 803, the active sprocket 804, the driven sprocket 805 and the synchronous chain 806, the liquid oil in the pumping cylinder 3 can be squeezed into the oil outlet pipe 4 through the oil outlet one-way valve 11, and then enter the oil storage cylinder 1.

[0025] When the utility model is in use, when the staff puts the fixed seat 2 on the upper end of the oil storage cylinder 1, the staff uses both hands to pull the synchronous moving block 1001 symmetrically arranged on the outer wall adjustment rod 1007 of the fixed seat 2 at the same time, and the synchronous moving block 1001 can drive the linkage rope 1002 to pull the clamping frame 1003 arranged at 90 degrees to slide in the stable frame at the same time, and the adjustment spring 1006 is gradually stretched, and then the staff puts one end of the clamping frame 1003 on the upper end circumferential outer wall of the oil storage cylinder 1, so as to clamp the oil storage cylinders 1 of different sizes, and then the staff connects one end of the oil outlet pipe 4 with the inside of the oil storage cylinder 1, and then the staff turns on the driving motor 801, and the driving motor 801 drives the active screw 802 to rotate, through the rotation of the active screw 802 and the active sprocket 804 and the driven sprocket 8 05 In addition, the cooperation of the synchronous chain 806 can make the driven screw 803 rotate, and at this time, the pumping piston 6 that is rotatably engaged with the active screw 802 and the driven screw 803 can slide and rise and fall in the pumping cylinder 3. At this time, the sealing fit between the pumping piston 6 and the inner wall of the pumping cylinder 3 can increase the negative pressure in the pumping cylinder 3, so that the oil inlet pipe 5 under the action of the oil inlet check valve 12, the external oil is pumped from the oil inlet pipe 5 into the pumping cylinder 3, and the oil intake amount in the pumping cylinder 3 can be judged by the scale line 9. The pumping cylinder 3 is made of transparent material. At this time, when the staff extracts a certain amount of liquid oil, the staff controls the drive motor 801 to reverse the output end of the drive motor 801 as the servo motor. At this time, the pumping piston 6 squeezes the liquid oil into the oil outlet pipe 4, and the liquid oil can be squeezed into the oil storage cylinder 1 through the oil outlet check valve 11, thereby realizing the quantitative extraction of liquid oil.
