[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figure 1-6 This embodiment provides the following technical solution: an electric lubrication pump device, including a pump body 1 and a piston rod 4. The bottom of the pump body 1 is provided with an oil inlet chamber 2. A pump cylinder 3 is fixedly connected inside the oil inlet chamber 2. The top end of the pump cylinder 3 is threadedly connected to the inside of the oil inlet chamber 2. The other end of the pump cylinder 3 is fixedly connected to a filter cylinder 6 through a connecting sleeve 5. One end of the connecting sleeve 5 is threadedly connected to the inside of the bottom end of the pump cylinder 3, and the other end of the connecting sleeve 5 is threadedly connected to the top end of the filter cylinder 6. Filter holes are distributed on the side wall of the filter cylinder 6. When the filter cylinder 6 is inserted into the oil drum, it can facilitate the grease in the oil drum to enter the filter cylinder 6.

[0028] The piston rod 4 is a hollow structure with open ends. The piston rod 4 is movably inserted into the guide groove on the connecting sleeve 5. The bottom end of the piston rod 4 is fixedly connected to the sealing block 7. The side wall of the bottom end of the piston rod 4 is provided with an oil inlet groove 8. The top end of the piston rod 4 is located inside the pump cylinder 3, and the bottom end of the piston rod 4 is located inside the filter cylinder 6. The oil inlet groove 8 facilitates the entry of grease in the filter cylinder 6 into the cavity inside the piston rod 4.

[0029] The other end of the piston rod 4 is fixedly connected to the piston cylinder 10 through the first one-way valve 9. A sealing groove is provided on the outside of the piston cylinder 10. A sealing plug 17 is fixedly connected in the sealing groove and slidably connected to the inner wall of the pump cylinder 3. Through the sealing plug 17, the space between the inner wall of the pump cylinder 3 and the outer wall of the piston rod 4 can be divided into an upper chamber and a lower chamber. During the process of the piston rod 4 driving the piston cylinder 10 to move upward, the grease in the upper chamber can be squeezed out of the pump cylinder 3, and the grease in the oil tank can also enter the lower chamber of the pump cylinder 3 through the filter cylinder 6.

[0030] The other end of the piston cylinder 10 is fixedly connected to the oil outlet cylinder 12 via the second one-way valve 11. The side wall of the oil outlet cylinder 12 is provided with an oil outlet groove 13. The other end of the oil outlet cylinder 12 is fixedly connected to a sealing column 14. Through the oil outlet cylinder 12 and the second one-way valve 11, the grease in the lower chamber of the pump cylinder 3 can enter the upper chamber of the pump cylinder 3 through the cavity inside the piston rod 4.

[0031] Oil drain grooves 15 are provided on both the left and right sides above the oil inlet chamber 2 on the pump body 1. One end of the oil drain groove 15 is connected to the oil inlet chamber 2, and the other end of the oil drain groove 15 is fixedly connected to the oil drain nozzle 16. Through the oil drain grooves 15, when the piston rod 4 moves upward, the grease in the upper cavity of the pump barrel 3 can move upward along the pump barrel 3 until the grease is sent into the oil drain grooves 15 on both sides, so that the grease can replenish the mechanical lubrication parts and play a lubricating role.

[0032] The pump body 1 is provided with a drive chamber 18, and a drive rod 19 is slidably connected in the drive chamber 18. The top end of the drive rod 19 is connected to the reciprocating drive mechanism provided in the drive chamber 18. The other end of the drive rod 19 extends into the oil inlet chamber 2 and is fixedly connected to the sealing column 14. It is used to make the piston rod 4 reciprocate up and down in the pump barrel 3. Through the drive rod 19, the piston rod 4 can be driven to reciprocate vertically along the pump barrel 3 to complete the purpose of grease pumping.

[0033] The reciprocating drive mechanism includes a drive block 20 and an eccentric block 23. The drive block 20 is slidably connected to the drive cavity 18 via a guide rail 21. The drive block 20 is fixedly connected to the reciprocating rod. A sliding groove 22 is provided on the drive block 20. The eccentric block 23 is slidably connected inside the sliding groove 22. In some embodiments, two guide rails 21 are provided, and the two guide rails 21 are respectively provided on both sides of the drive block 20. The two guide rails 21 work together to form a limiting structure for the vertical movement of the drive block 20. During the eccentric movement of the eccentric block 23, the eccentric block 23 will reciprocate in the left and right directions within the movable groove in the drive block 20. Under the limiting action of the guide rail 21, the eccentric movement of the eccentric block can be converted into the linear movement of the drive block 20, so that the drive block 20 performs reciprocating movement in the vertical direction.

[0034] A drive motor is fixedly connected to the pump body 1. The output shaft of the drive motor extends into the drive chamber 18 and is fixedly connected to a drive disk 24. An eccentric shaft 25 is fixedly connected to the edge of the drive disk 24. The eccentric shaft 25 is fixedly connected to the shaft groove provided on the eccentric block 23. The drive motor can drive the drive disk 24 to drive the eccentric shaft 25 to rotate eccentrically, thereby enabling the eccentric block 23 to move eccentrically within the drive chamber 18.

[0035] A pump cover 26 is detachably connected to the pump body 1. In some embodiments, the pump cover 26 is fixedly connected to the pump body 1 by screws. The pump cover 26 can make the drive chamber 18 open or closed, which is also conducive to the disassembly or maintenance of the mechanical equipment in the drive chamber 18.

[0036] The working principle of this utility model is as follows: When lubricating oil needs to be replenished, the drive motor is started, which drives the drive disc 24 and the eccentric shaft 25 to perform eccentric motion. With the cooperation of the guide rail 21 and the sliding groove 22, the drive block 20 drives the drive rod 19 to drive the piston rod 4 to perform vertical reciprocating motion in the pump cylinder 3. When the piston rod 4 moves upward, under the pressure change in the upper and lower chambers of the pump cylinder 3, the first one-way valve 9 is in the closed state and the second one-way valve 11 is in the open state. The grease in the upper chamber of the pump cylinder 3 will be discharged from the top of the pump cylinder 3, and the discharged grease will enter the oil drain groove 15, thereby completing the oil replenishment operation of the lubrication part of the mechanical equipment.

[0037] As the piston rod 4 moves upward, the negative pressure in the lower chamber of the pump cylinder 3 gradually increases, causing the grease in the oil drum to pass through the filter cylinder 6 and enter the pump cylinder 3, thus allowing the grease to enter the lower chamber of the pump cylinder 3.

[0038] When the piston rod 4 moves downward, both the first one-way valve 9 and the second one-way valve 11 are open, allowing the grease in the lower chamber of the pump cylinder 3 to enter the cavity of the piston rod 4 through the oil inlet groove 8. The grease in the cavity of the piston rod 4 then enters the oil outlet cylinder 12 through the first one-way valve 9, the piston cylinder 10, and the second one-way valve 11. The grease in the oil outlet cylinder 12 then enters the upper chamber of the pump cylinder 3 through the oil outlet groove 13. Similarly, during the reciprocating motion of the piston rod 4, the grease enters the pump cylinder 3 and then enters the oil discharge groove 15, thus completing the purpose of oil extraction and delivery.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
