[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-4 The reciprocating high-speed lubricating oil pump in this embodiment includes a motor 3 fixed on a base 1, a transmission box 2 and a piston cylinder 8 connected to one end of the transmission box 2. A transmission component is provided in the transmission box 2 for completing the reciprocating movement. A piston disc 9 is movably installed in the piston cylinder 8 for forming a negative pressure to suck the lubricating oil.

[0023] In this embodiment, four openings are provided on the outer wall of the piston cylinder 8, and the four openings are located at the upper and lower positions at both ends of the piston cylinder 8. A three-way pipe 10 is connected between the two openings on the same side. The two three-way pipes 10 are respectively used to complete oil intake and oil pumping, and a one-way valve is installed at the four openings of the piston cylinder 8.

[0024] The present application improves the prior art by providing two openings at one end of the piston cylinder 8, and adding a pair of outlets for oil intake and oil pumping, so that the double-sided movement of the piston disk 9 in the piston cylinder 8 can achieve oil pumping, thereby improving the oil pumping efficiency without changing the power effect of the motor 3.

[0025] It should be noted that the transmission component includes a worm 4 connected to the power end of the motor 3, and a worm wheel 5 rotatably mounted on the inner wall of the transmission box 2. The worm 4 is meshed with the worm wheel 5. The rotation of the worm wheel 5 can drive the worm 4 to rotate.

[0026] It also includes a crosshead 7 connected to the worm gear 5 and slidably installed in the transmission box 2. One end of the crosshead 7 is fixedly connected to the piston disc 9, and the other end is rotatably connected to a swing rod 6 rotatably connected to the worm gear 5.

[0027] In a specific implementation, the swing rod 6 can rotate synchronously with the worm gear 5 , so that the swing rod 6 drives the crosshead 7 to slide back and forth relative to the transmission box 2 .

[0028] Specifically, a connecting shaft 16 is fixedly installed inside the crosshead 7, and one end of the swing rod 6 is rotatably connected to the outside of the connecting shaft 16, so that the swing rod 6 can swing relative to the crosshead 7;

[0029] A positioning pin 11 is rotatably mounted on the outer circumference of the worm wheel 5 , and the end of the swing rod 6 transitions into a rectangular shape and is rotatably connected to the positioning pin 11 , so that the swing rod 6 can rotate relative to the positioning pin 11 .

[0030] In order to adjust the specific distribution position of the piston disk 9 in the piston cylinder 8, in this embodiment, an adjusting rod 14 is threadedly installed on one end of the transmission box 2, and a slider 13 is rotatably installed on one end of the adjusting rod 14. The slider 13 slides against the inner wall of the transmission box 2, and a rotating rod 12 is rotatably installed on the front side of the slider 13. The worm gear 5 is penetrated by the rotating rod 12, so that the worm gear 5 can rotate relative to the slider 13 and can change position as the slider 13 slides.

[0031] In this embodiment, a handle 15 is fixedly mounted on one end of the adjusting rod 14 that passes through the outside of the transmission box 2 , and the rotation of the adjusting rod 14 can be conveniently adjusted by rotating the handle 15 .

[0032] In the present application, a piston disc 9 connected by a swing rod 6 and a crosshead 7 is arranged to slide back and forth in a piston cylinder 8, and a one-way valve is used to form negative pressure and positive pressure in the piston cylinder 8 to pump the lubricating oil. At the same time, openings are opened at both ends to connect them through a three-way pipe 10, so that the reciprocating motion trajectory of the piston disc 9 on both sides can act on the formation of a negative pressure pumping effect, so that on the basis of the power of the original motor 3, the pumping efficiency can be effectively improved, and an adjusting rod 14 is arranged to connect the slider 13 and the rotating rod 12, so that the position of the piston disc 9 can be adjusted to a certain extent, thereby improving the practicality of the device.

[0033] The working principle of the above embodiment is:

[0034] By rotating the handle 15 located outside the transmission box 2, the handle 15 drives the fixedly connected adjusting rod 14 to rotate synchronously. The adjusting rod 14 is threadedly matched with the transmission box 2 under rotation, so as to adjust the position of the slider 13 connected to the end of the adjusting rod 14. The slider 13 slides in contact with the inner wall of the transmission box 2, and synchronously drives the rotating rod 12 located on the slider 13 to move. At this time, the worm wheel 5 changes its relative position relative to the worm 4, so that the swing rod 6, the crosshead 7 and the piston disc 9 connected to the outside of the worm wheel 5 adjust their positions. Then the motor 3 is controlled, and the power end of the motor 3 drives the worm 4 to rotate. The worm 4 meshes with the worm wheel 5 under rotation, so that the worm wheel 5 rotates relative to the rotating rod 12. At this time, the swing rod 6 connected to the outside of the worm wheel 5 swings in an arc trajectory, so that the crosshead 7 connected to the swing rod 6 moves back and forth relative to the transmission box 2, and drives the piston disc 9 to swing back and forth in the piston cylinder 8. The four openings at both ends of the piston cylinder 8 respectively complete the negative pressure suction and pumping of lubricating oil, thereby realizing reciprocating high-pressure oil pumping.
