DETAILED DESCRIPTION

[0017] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0018] Embodiments of the present invention: Figure 1 As shown, a refueling device with a metering function includes a refueling device 1, a refueling nozzle 2 and an oil quantity recording device. The refueling device 1 can adopt a manual lubricating oil refueling gun or an electric lubricating oil refueling machine. The oil quantity recording device includes a shell 3, a pushing wheel 4, an oil guiding mechanism 5 and a metering device 6. The shell 3 is provided with an oil inlet pipe 7 and an oil outlet pipe 8. The metering device 6 is fixed on the oil outlet pipe 8. The oil inlet pipe 7 is connected to the refueling device 1 through a soft connecting pipe 21. The pushing wheel 4 is rotatably installed in the shell 3. The pushing wheel 4 has alternating convex and concave surfaces. The oil guiding mechanism 5 is installed in the oil outlet pipe 8 and can slide between a first working position and a second working position. When it is in the first working position, one end of the oil guiding mechanism 5 is located at the highest point of the convex surface, and the other end abuts against the metering device 6. When it is in the second working position, one end of the oil guiding mechanism 5 is located at the lowest point of the concave surface and abuts, and the other end is separated from the metering device 6; the oil guiding mechanism 5 is connected to the refueling nozzle 2 through a hose 9.

[0019] During operation, the oiling nozzle 2 is connected to the equipment to be lubricated, and then oil is added through the oiler 1. The oiler 1 injects lubricating oil into the housing 3 through the oil inlet pipe 7. The lubricating oil fills the concave surface of the push wheel 4 and causes the push wheel 4 to rotate. As the push wheel 4 rotates and the oil guide mechanism 5 moves between the first working position and the second working position, oil delivery and counting are achieved. The specific principle is that one end of the oil guide mechanism 5 is always in contact with the push wheel 4. When it interacts with the concave surface, the lubricating oil in the concave surface is scraped out and squeezed out through the hose 9 and the oiling nozzle 2. When it interacts with the highest point of the convex surface, the other end interacts with the metering device 6, and the metering device 6 counts once. Since the amount of lubricating oil that each concave surface can accommodate is the same, the amount of oil added can be determined based on the count on the metering device 6. The counting device 6 can be a purely mechanical counter or an electronic counter. The present invention can effectively control the amount of oil added and achieve accurate oiling, which not only reduces the waste of lubricating oil but also helps to increase the operating life of the equipment.

[0020] In a specific embodiment, the outer shell 3 includes a shell 10 and a cover plate 11. The shell 10 is a cylindrical structure with an installation cavity inside. The shell 10 and the cover plate 11 both have threaded holes. The cover plate 11 is fixed to the shell 10 by bolts. The push wheel 4 is rotatably installed in the installation cavity through the rotating shaft 12. Preferably, the rotating shaft 12 is a one-way rotating shaft, which can only rotate in the clockwise direction, that is, the push wheel 4 can only rotate clockwise. The oil inlet pipe 7 and the oil outlet pipe 8 are both fixed on the side of the shell 10 and are both connected to the installation cavity.

[0021] Furthermore, the propulsion wheel 4 is preferably provided with four convex surfaces and four concave surfaces, each of which is arc-shaped, with a smooth transition between adjacent convex and concave surfaces. The angle between the oil inlet pipe 7 and the oil outlet pipe 8 is 90 degrees. The provision of four convex and concave surfaces facilitates machining of the propulsion wheel 4 and oil volume control. This structural design also facilitates coordination with the oil guide mechanism 5, preventing jamming. The use of a one-way shaft 12 enhances the precision of the present invention and prevents the propulsion wheel 4 from reversing.

[0022] It should be noted that the oil guide mechanism 5 and the push wheel 4 can be matched in various forms. This embodiment adopts a structural form that is simple to match and easy to set up, but other structural forms that can meet the use requirements can be applied to the present invention.

[0023] Specifically, if Figure 2 and Figure 3 As shown, the oil outlet pipe 8 is a cylindrical structure, and the interior of the oil outlet pipe 8 is provided with an oil guide mechanism mounting cavity 13, an oil pipe accommodating hole 14 and a push rod mounting hole 15. The oil pipe accommodating hole 14 and the push rod mounting hole 15 are arranged in parallel and are both connected to the oil guide mechanism mounting cavity 13. The oil guide mechanism 5 can be slidably installed in the oil guide mechanism mounting cavity 13.

[0024] The oil guide mechanism 5 includes a guide column 16, a fan-shaped slider 17, an oil guide pipe 18 and a push rod 19. The guide column 16 slides in cooperation with the oil guide mechanism mounting cavity 13. The fan-shaped slider 17 is provided at one end of the guide column 16 and abuts against the push wheel 4. The oil guide pipe 18 and the push rod 19 are provided at the other end of the guide column 16. The oil guide pipe 18 extends out of the oil pipe 8 through the oil pipe accommodating hole 14 and is connected to the hose 9; the push rod 19 is plugged into the push rod mounting hole 15, and a return spring 20 is sleeved on the push rod 19. One end of the return spring 20 abuts against the end face of the guide column 16, and the other end abuts against the side wall of the oil guide mechanism mounting cavity 13. The micro switch 22 on the metering device 6 is accommodated at one end in the push rod mounting hole 15; a through oil guide channel is provided in the guide column 16, and the oil guide channel is connected to the oil guide pipe 18.

[0025] The sector-shaped slider 17 is configured to better cooperate with the concave surface of the push wheel 4, completely scraping off the lubricating oil. The lubricating oil is then pressed into the oil guide channel and oil guide pipe 18, then into the hose 9 along the oil guide pipe 18, and finally into the equipment to be lubricated through the oil filling nozzle 2. The function of the return spring 20 is to provide thrust for the guide column 16, so that the sector-shaped slider 17 always presses against the push wheel 4. When the oil guide mechanism 5 is in the first working position, the sector-shaped slider 17 contacts the highest point of the convex surface, and the push rod 19 contacts the metering device 6. When the oil guide mechanism 5 is in the second working position, the sector-shaped slider 17 contacts the lowest point of the concave surface, and the push rod 19 is separated from the metering device 6.

[0026] Since the diameters of the oil guide channel and the oil guide pipe 18 are relatively small, in order to allow the lubricating oil to smoothly enter the oil guide channel, preferably, the opening of the oil guide channel at one end of the sector-shaped slider 17 is designed as an “R”-shaped opening 23 .

[0027] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
