[0020] Optionally, a drive motor is installed inside the housing, and the output shaft of the drive motor is connected to a stirring shaft located inside the storage tank.

[0021] By adopting the above technical solution, the drive motor is started and the stirring shaft works. The stirring shaft continuously stirs the grease to prevent it from solidifying and being unable to flow out of the grease outlet, thus maintaining the fluidity of the grease.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the pump is running, the grease is discharged through the grease outlet pipe.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to all the accompanying drawings.

[0026] This application discloses a lubrication pump that facilitates the replenishment of grease.

[0027] like Figure 1 A lubrication pump for convenient grease replenishment includes a housing 1, a storage tank 2 for storing grease mounted on top of the housing 1, a grease outlet pipe 12 connected to one side of the housing 1, and a grease injection pipe 13 connected to the storage tank 2 installed on one side of the housing 1. When grease needs to be replenished, a manual grease gun can replenish grease into the storage tank 2 through the grease injection pipe 13.

[0028] like Figure 2 and Figure 3 The end of the grease injection tube 13 is threaded with a sealing cap 132 to prevent dust from entering the end of the grease injection tube 13 and to avoid contamination of the grease with dust. A connecting rope 133 is installed on the outer wall of the grease injection tube 13, and the end of the connecting rope 133 is connected to the sealing cap 132. The connecting rope 133 connects the grease injection tube 13 and the sealing cap 132 together to prevent the sealing cap 132 from being lost.

[0029] like Figure 2 , Figure 3 and Figure 4 A limiting component 3 is installed on the grease injection tube 13. The limiting component 3 includes a cylinder 36 and a support column 31. The cylinder 36 is located inside the housing 1. A pump body 11 is installed at the bottom of the housing 1, and a support block is installed above the pump body 11. The cylinder 36 is mounted on the support block. Several moving rods 35 are fixedly connected to the end of the piston rod of the cylinder 36. Each of the moving rods 35 has a connecting rod 34 installed at its end. The length direction of the connecting rods 34 is the same as the moving path of the piston rod of the cylinder 36. Several connecting holes 14 are provided on the housing 1 to cooperate with the moving rods 35. When the cylinder 36 is started, the piston rod of the cylinder 36 extends, driving the moving rods 35 to move. The connecting rods 34 move along the moving direction of the piston rod of the cylinder 36 through the connecting holes 14, realizing the reciprocating movement of the connecting rods 34 driven by the extension and retraction of the piston rod of the cylinder 36.

[0030] One end of the support column 31 is fixedly connected to the housing 1. A fixed slot 311 is opened in the center of the support column 31. The grease injection tube 13 is located in the fixed slot 311. Several fixed blocks 32 are installed at the end of the support column 31 away from the housing 1. Each of the fixed blocks 32 has a limit groove 321. Each of the limit grooves 321 has a limit block 33 installed in it. The limit block 33 is hinged to its corresponding fixed block 32. A connecting groove 331 is opened at the end of the limit block 33 near the connecting rod 34. The limit block 33 corresponds to the connecting rod 34 one by one. The connecting rod 34 is located in the connecting groove 331. Sliding columns 341 are fixedly installed on both sides of the connecting rod 34. Sliding slots 332 that communicate with the connecting grooves 331 are opened on both sides of the limit blocks 33. The sliding columns 341 are located in the sliding slots 332 and are movably connected to the limit blocks 33. When the user applies grease with a manual grease gun, the connecting rod 34 moves, and the sliding column 341 on the connecting rod moves within the sliding groove 332, causing the limiting block 33 to rotate. The limiting block 33 clamps the manual grease gun, thus limiting the manual grease gun without requiring the user to hold it, improving the convenience of applying grease with a manual grease gun.

[0031] like Figure 2 and Figure 4 A limiting post 37 is installed at the end of the fixing block 32 away from the supporting post 31. The limiting post 37 has a central slot 371. A friction block 333 is provided at the end of the limiting block 33 near the fixing slot 311. The limiting post 37 fixes the limiting block 33. The friction block 333 is made of elastic rubber. The friction block 333 buffers the limiting block 33 when it grips the manual grease gun, preventing direct contact between the limiting block 33 and the manual grease gun and preventing damage to the manual grease gun.

[0032] like Figure 3 and Figure 5 The pump body 11 is connected to the storage tank 2 and the grease outlet pipe 12. A drive motor 15 is installed on top of the pump body 11, and the output shaft of the drive motor 15 is connected to a stirring shaft 21 located inside the storage tank 2. When the drive motor 15 is started, the stirring shaft 21 works, continuously agitating the grease to prevent it from solidifying and flowing out of the grease outlet pipe 12, thus maintaining the fluidity of the grease. As the pump body 11 operates, the grease is discharged through the grease outlet pipe 12.

[0033] like Figure 4 The grease injection pipe 13 is equipped with a one-way valve 131 that allows grease to enter the storage tank 2. The one-way valve 131 controls the flow direction of the grease and prevents the grease from flowing back.

[0034] like Figure 5 The storage tank 2 is threadedly connected to the shell 1, which enables the storage tank 2 and the shell 1 to be detachably connected, facilitating the maintenance and cleaning of the lubrication pump in the future.

[0035] The implementation principle of a lubrication pump for convenient grease replenishment in this application embodiment is as follows: The user rotates to open the sealing cover 132, aligns the manual grease gun with the grease injection tube 13 for grease injection, starts the cylinder 36, the piston rod of the cylinder 36 extends, the moving rod 35 moves, the connecting rod 34 moves along the moving direction of the piston rod of the cylinder 36, the sliding column 341 on the connecting rod 34 slides in the sliding groove 332, driving the limiting block 33 to rotate, the limiting block 33 clamps the manual grease gun, realizing the limiting of the manual grease gun by the limiting block 33, and the friction block 333 on the limiting block 33 buffers when the limiting block 33 clamps the manual grease gun, realizing grease injection without holding the manual grease gun, improving the convenience of replenishing grease with the manual grease gun.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
