For a better understanding of this patent, preferred embodiments of this patent are described in detail below with reference to the accompanying drawings. It should be understood by those skilled in the art that these exemplary embodiments are not meant to limit the patent form in any way.
Referring to fig. 1-10, a battery type grease gun capable of being filled with a plurality of sealed grease cartridges includes a main body casing 1, a handle 2 is disposed at an upper portion of the main body casing 1, a battery mounting seat 3 for mounting a battery pack 4 is disposed at a rear portion of the handle 2, and the battery pack 4 can be easily replaced. The inside of main part casing 1 set up the motor, with drive mechanism that the motor is connected, with drive mechanism connected's plunger, battery package 4 provide the power, the drive the motor, drive plunger reciprocating motion, constantly extrude the butter. The lower part of main part casing 1 set up and converge a flow seat 5 and a grease section of thick bamboo 6, a grease section of thick bamboo 6 be used for depositing the butter, the one end of a grease section of thick bamboo 6 pass through the screw thread with converge a flow seat 5 cooperation, the other end passes through screw thread installation oil section of thick bamboo spiral cover 10, main part casing 1 still set up ring carrier 7 will a grease section of thick bamboo 6 fix, the export of a flow seat 5 that converges set up out oil nozzle 8, oil nozzle 8 connect out oil pipe 9, the compound motion of plunger, the extrusion converge the butter in the flow seat 5, the butter is followed oil nozzle 8 blowout, get into play oil pipe 9.
In order to push the grease in the grease cylinder 6 into the confluence seat 5 continuously, a push rod is arranged in the grease cylinder 6. The push rod is provided with a handle 11 for people to operate. The handle 11 is connected with a slender pull rod 12, the pull rod 12 penetrates through a central hole of the oil cylinder screw cap 10, the other end of the pull rod 12 is positioned inside the grease cylinder 6 and is provided with a sealing ring 17, a sealing ring inner pressing plate 16 and a sealing ring supporting frame 14 are respectively arranged on the inner side of the sealing ring 17, and a gasket 18 and a sealing ring outer pressing plate 19 are respectively arranged on the outer side of the sealing ring 17; the sealing ring 17, the sealing ring inner pressing plate 16 and the sealing ring outer pressing plate 19 are symmetrically provided with at least one group of fixing holes 22 on the circumference, and the connecting piece 15 is arranged to penetrate through the fixing holes 22 to connect the sealing ring 17, the sealing ring inner pressing plate 16 and the sealing ring outer pressing plate 19 into a whole.
Preferably, the connecting member 15 is provided as a rivet. It will be appreciated that the connector 15 may also be provided as a screw and nut.
Specifically, the sealing ring 17 is of a bowl-shaped rubber structure, the edge thickness is small, and the diameter is larger than the inner diameter of the grease barrel 6, so that the sealing requirement is met.
A compression spring 13 is arranged between the sealing ring support frame 14 and the oil cylinder screw cap 10. The compression spring 13 applies pressure to the grease in the grease cylinder 6 through the sealing ring support frame 14, and pushes the confluence seat 5.
Further, a cylindrical pin 20 is arranged at the tail end of the pull rod 12, and an opening is arranged in the center of the sealing ring outer pressing plate 19 and allows the cylindrical pin 20 to pass through. The opening is arranged in a strip shape, and the size of the opening is larger than that of the cylindrical pin 20. Thus rotating the handle 11 to align and insert the cylindrical pin 20 with the opening of the outer seal ring pressure plate 19, and then rotating 90 degrees to lock between the spacer 18 and the outer seal ring pressure plate, thereby securing the pull rod 12 to the seal ring 17; conversely, the pull handle 11 is rotated to align and extend the cylindrical pin 20 with the opening of the outer pressing plate 19 of the sealing ring, and the pull rod 12 can freely move between the bottom of the grease cylinder 6 and the sealing ring 17.
Furthermore, a limiting groove 21 is formed in the pull rod 12, a limiting hole 23 is formed beside the central hole of the oil cylinder screw cap 10, and the diameter of the limiting hole 23 is smaller than that of the pull rod 12 and larger than the inner diameter of the limiting groove 21. Therefore, after the limiting groove 21 is clamped into the limiting hole 23, the position of the pull rod 12 can be fixed. The oil cylinder screw cap 10 is provided with at least one exhaust hole 24, and air between the sealing ring 17 and the oil cylinder screw cap 10 is exhausted in the process of pulling up the pull rod 12.
When the butter cylinder 6 is filled with the bulk butter, the cylindrical pin 20 penetrates into the sealing ring outer pressing plate 19 and the sealing ring 17 to be fixed, then the sealing ring 17 is arranged at the bottom of the butter cylinder 6, then the bottom of the butter cylinder 6 is immersed into the bulk butter, the handle 11 is pulled up to slowly pull the sealing ring 17 towards the top of the butter cylinder 6, in the process, the bulk butter is sucked into the butter cylinder 6, and the air can be discharged through the exhaust hole 24 and the limiting hole 23 on the butter cylinder screw cap 10. When the sealing ring 17 compresses the compression spring 13 to the limit position, the pull rod 12 swings through the handle 11 to clamp the limit groove 21 into the limit hole 23, and the push rod is fixed. And (3) mounting the butter cylinder 6 on the confluence seat 5, and then separating the limiting groove 21 from the limiting hole 23 to finish the filling of the bulk butter. Then, if the cylindrical pin 20 is retained in the sealing ring outer pressing plate 19, the length of the pull rod 12 outside the grease cylinder 6 can represent the amount of residual grease; the cylindrical pin 20 can also be separated from the sealing ring outer pressing plate 19, and the pull rod 12 is restored to the bottom of the grease cylinder 6, so that the occupied space is reduced, and the operation is convenient.
When the grease cylinder 6 is filled with the grease bombs of the caterpillar, the cylindrical pin 20 firstly penetrates into the sealing ring outer pressing plate 19 to be fixed with the sealing ring 17, the handle 11 pulls the sealing ring 17 to the top of the grease cylinder 6, the pull rod 12 is swung to clamp the limiting groove 21 into the limiting hole 23, and the push rod is fixed. Then the grease cartridge 6 is filled with the "caterpillar" grease. The grease cylinder 6 is arranged on the confluence seat 5, and then the limiting groove 21 is separated from the limiting hole 23, so that the filling of the 'caterpillar' grease bullet is completed.
When the butter cylinder 6 is filled with sealed canned butter bullets, the cylindrical pin 20 penetrates into the sealing ring outer pressing plate 19 to be fixed with the sealing ring 17, the sealing ring 17 is pulled to the top of the butter cylinder 6 through the handle 11, the pull rod 12 is swung to clamp the limiting groove 21 into the limiting hole 23, and the push rod is fixed. Then the plastic cover and the easy-to-pull cover at the two ends of the sealed grease bomb are removed, and the grease cylinder 6 is filled according to the direction marked on the package. The grease cylinder 6 is arranged on the confluence seat 5, then the limit groove 21 is separated from the limit hole 23, then the handle 11 is pushed towards the bottom of the grease cylinder 6, the sealing ring 17 is squeezed into a packaging cylinder 25 of the sealed canned grease ball, and the filling of the sealed canned grease ball is finished. At this time, the structure of the sealing ring 17 allows the outer edge to be locally deformed, and the whole structure is kept stable, so that the sealing requirement can be still met. Finally, if the cylindrical pin 20 is retained in the sealing ring outer pressing plate 19, the length of the pull rod 12 outside the grease cylinder 6 can represent the amount of residual grease; the cylindrical pin 20 can also be separated from the sealing ring outer pressing plate 19, and the pull rod 12 is restored to the bottom of the grease cylinder 6, so that the occupied space is reduced, and the operation is convenient.
In addition to the preferred embodiments described above, other embodiments of the present patent will suggest themselves to those skilled in the art, and all changes and modifications that fall within the spirit of the patent are intended to be embraced by the scope of the appended claims.
