Description

Technical Field

[0001] This utility model belongs to the field of oil suction technology, specifically, it relates to a press-type automatic oil suction device. Background Technology

[0002] An oil suction device is a device that draws oil from one location and transports it to another. As an oil extraction tool, oil suction devices are widely used in industries such as metal smelting, chemical production, machining, and oil extraction. Currently, the main oil suction device used in industrial applications is the oil suction pump, which is further divided into electric oil suction pumps and hand-cranked oil pumps. Electric oil suction pumps are used in fixed oil suction locations, while hand-cranked oil pumps are more widely used in oil dispensing, oil filling, and oil storage and transportation in various industries due to their advantages such as simple structure, reliable operation, low price, and convenient operation and portability.

[0003] The hand-cranked oil pump, as the most commonly used manual oil suction device, works on the following principle: when the handle is cranked back and forth by hand, the piston or scraper rotates through the transmission mechanism such as the shaft, rocker arm, and connecting rod. The volume of the pump cylinder gradually expands, forming a vacuum. Under the action of atmospheric pressure, the oil is drawn in from the oil suction port on one side of the cylinder and discharged from the oil discharge port on the other side of the cylinder at the same time. By continuously cranking the handle, the oil is continuously drawn in and discharged, thus realizing the extraction of oil.

[0004] In industrial production, it is necessary to regularly add or change lubricating oil for equipment such as speed reducers, water pumps, and fans. Due to the strict management requirements for lubricating oil, it needs to be stored in designated locations. Furthermore, the oil storage containers themselves are large and heavy, making them extremely inconvenient to move. The common method is to use an SL-type hand-cranked oil pump to draw lubricating oil from the storage container and distribute it into a dispensing container or can before adding it to the equipment's lubrication chamber. Although the SL-type hand-cranked oil pump has a simple structure and is easy to operate, it requires continuous cranking of the handle to draw oil. Therefore, it often requires one person to hold the oil pipe and the dispensing container or can while another person cranks the pump handle. Two people working together are needed to complete the oil suction operation. Moreover, the labor intensity is high, and the physical exertion is significant, often resulting in arm fatigue for the operators, frequently necessitating breaks. Summary of the Invention

[0026] The oil outlet pipe 5 is connected to the lower side of the cylinder body 31 and is connected to the cylinder body 31. The oil outlet pipe 5 is equipped with a switch valve 4, which is a GB / T 12237-2021 double internal thread butterfly ball valve.

[0027] As a preferred option, the lower end of the switch valve 4 is connected to the oil outlet pipe 5, and the lower end of the oil outlet pipe 5 is extended to connect to a flexible pipe. The length of the flexible pipe can be changed as needed. The flexible pipe is easier to retract and easier to insert into the oil receiving bucket or oil can.

[0028] As a preferred embodiment, the oil suction pipe 1 is equipped with a mounting base 2, which has a quincunx-shaped structure. The lower end face of the mounting base 2 has a threaded connector 21 for connection to the oil cylinder.

Install a flexible hose at the oil outlet pipe 5 with a length exceeding 150% of the total length of the suction pipe 1, ensuring its outlet is lower than the suction port at the bottom of the suction pipe 1. Open the switch valve 4 and press the push handle 37, causing the piston 34 to move downwards and compress the return spring 36 to its lower limit position, expelling air from the cylinder 31 through the suction pipe 1 and the oil outlet pipe 5. Release the push handle 37; the piston 34 moves upwards under the action of the return spring 36, and the oil in the oil storage tank enters the cylinder 31 along the suction pipe 1 under atmospheric pressure. Repeatedly and quickly press the push handle 37 to expel as much air as possible from the cylinder 31 and the suction pipe 1 until oil flows out of the oil outlet pipe 5. Stop pressing and return the push handle 37 to its original position. The oil flows into the dispensing tank or oil can. Close the switch valve 4 only after the dispensing tank or oil can has filled enough oil to meet the refueling requirements. If you need to temporarily interrupt oil extraction, simply close the switch valve 4 and open the switch valve 4 when you want to extract oil again. There is no need to repeatedly and quickly press and release the hand plate 37.

[0033] Rotate the mounting base 2 to separate the threaded connector 21 from the oil outlet of the oil storage tank, pull out the oil suction pipe 1, open the switch valve 4, and repeatedly push and press the hand plate 37 multiple times to force out and drain the oil in the chamber of the pusher 3.
