Description

Technical Field

[0001] The utility model relates to an oil extraction pump, in particular to a quick-disassembly structure of an electric oil extraction pump. Background Art

[0002] The electric oil extraction pump efficiently and quickly transfers oil from one place to another, and is widely used in the fields of industry, agriculture, transportation, etc.

[0003] The existing electric oil extraction pump includes an oil pump body provided with an oil suction pipe and an oil outlet pipe. During use, the oil suction pipe is inserted into an oil barrel, the oil outlet pipe is inserted into a specific place, and after the switch is turned on, the impeller inside the oil pump body rotates. The high-speed rotation of the impeller generates low pressure at the oil inlet part, forming suction force to suck the oil into the oil pump body. The sucked oil is pressurized under the action of the impeller, and the pressurized oil is transported to the required place through the oil outlet pipe.

[0004] However, during the operation of the electric oil extraction pump, including before and after use, the individual connection and separation of the oil suction pipe and the oil outlet pipe are required. This procedure not only increases the operation time and labor cost, but also due to repeated plugging and unplugging actions, the joint of the oil suction pipe and the oil outlet pipe will gradually wear. With the loss of the joint, the sealing performance between the oil suction pipe and the oil outlet pipe and the oil pump body will be affected, thereby reducing the oil extraction efficiency and increasing the risk of oil leakage, which has a negative impact on the overall efficiency of the oil extraction operation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a quick-disassembly structure of an electric oil extraction pump, mainly to solve one or more of the above problems.

When the quick-disassembly part is in the locking position, the positioning convex part is positioned in the positioning hole, and when the quick-disassembly part is in the unlocking position, the positioning convex part is disengaged from the positioning hole.

[0007] The efficacy of the present utility model lies in that: The design of the electric oil pump of the present utility model adopts an innovative structure of the oil pump body and the tubing seat, in combination with the application of a quick-release component. When the quick-release component is in the locked position, oil-tight sealing can be achieved between the oil pump body and the tubing seat. When the quick-release component is pressed to the unlocked position, the tubing seat can be quickly and easily separated from the oil pump body. Therefore, the design of the present utility model allows for the simultaneous connection and separation of the suction pipe and the discharge pipe from the oil pump body through a single operation before and after use, greatly improving the operation efficiency and saving labor. In addition, since the connection and separation of the suction pipe and the discharge pipe are completed through the tubing seat, there is no need to repeatedly insert and remove the suction pipe and the discharge pipe, thereby reducing the wear at the joint, lowering the risk of oil leakage, and maintaining the high efficiency of the oil pumping operation.

[0046] The above is the structure and configuration description of the main components of the embodiment of the present utility model. The operation mode and efficacy of the present utility model are described as follows.

[0047] First, for separation. Refer to Figures 5 to 7As shown. Press the pressing portion 42 of the quick-release member 40, so that the quick-release member 40 is displaced from the locked position (such as Figure 5 ) to the unlocked position (such as Figure 6 ). At this time, the limiting ring portion 45 of the quick-release member 40 is away from the edge of the pressing hole 22 of the oil pump body 20, the positioning convex portion 43 of the quick-release member 40 is disengaged from the positioning hole 311 of the oil pipe seat 30, and at the same time, the second reset concave portion 44 of the quick-release member 40 presses against the reset spring 50 to accumulate an elastic restoring force. At this time, the oil pipe seat 30 and the oil pump body 20 are no longer restricted by the quick-release member 40. Refer to Figure 7 , so that the oil pipe seat 30 can be pulled off the oil pump body 20 to complete the separation operation between the oil pipe seat 30 and the oil pump body 20.

[0048] Second, perform the connection. Just operate in the reverse of the above separation steps, that is, first press the quick-release member 40 to the unlocked position (such as Figure 7 ), then insert the insertion portion 31 of the oil pipe seat 30 into the interface portion 21 of the oil pump body 20, and align the positioning hole 311 of the oil pipe seat 30 with the positioning convex portion 43 of the quick-release member 40 (such as Figure 6 ), and then release the pressing of the quick-release member 40, so that the quick-release member 40 is displaced from the unlocked position (such as Figure 6 ) to the locked position (such as Figure 5 ) by the elastic restoring force accumulated by the reset spring 50. At this time, the positioning convex portion 43 of the quick-release member 40 is inserted into the positioning hole 311 of the oil pipe seat 30, and the limiting ring portion 45 of the quick-release member 40 abuts against the edge of the pressing hole 22 of the oil pump body 20 to complete the connection operation between the oil pipe seat 30 and the oil pump body 20.

[0049] Accordingly, the design of the electric oil pump of the present utility model adopts an innovative structure of the oil pump body 20 and the oil pipe seat 30, in cooperation with the application of the quick-release member 40. When the quick-release member 40 is in the locked position, oil-tight sealing between the oil pump body 20 and the oil pipe seat 30 can be achieved. When the quick-release member 40 is pressed to the unlocked position, the oil pipe seat 30 can be quickly and easily separated from the oil pump body 20. Therefore, the design of the present utility model allows the simultaneous connection and separation of the oil suction pipe 11 and the oil discharge pipe 12 from the oil pump body 20 through a single operation before and after use, greatly improving the operation efficiency and saving labor. In addition, since the connection and separation of the oil suction pipe 11 and the oil discharge pipe 12 are completed through the oil pipe seat 30, there is no need to repeatedly insert and pull out the oil suction pipe 11 and the oil discharge pipe 12, thereby reducing the wear at the joint, reducing the risk of oil leakage, and maintaining the high efficiency of the oil pumping operation.
