Referring to Figures 1 to 4 the working relationship of the present invention configured as described above is as follows.

When grease is to be injected into each grease point of the vehicle, as shown in FIG. 1, a 20-litre grease, which is widely sold on the market, is purchased. Put it upright on the grease box (5) installed in the vehicle in the state.

Thereafter, the grease injection device 6 of the present invention is installed on the top of the grease container 1, and the suction pipe 14 of the grease injection device 6 is attached to the grease 100 contained in the grease container 1. The suction pipe 14 is inserted downward and the air pump 11 faces the upper side of the grease barrel 7 with the grease barrel lid 7 on the upper side so that the air pump 11 faces the spring hook portion 15 of the grease barrel lid 7. A spring 16 is installed between the spring hook portion 5a of the grease pail mount 5 and the grease injection device 6 is firmly installed on the top of the grease pail mount 5. Even when the vehicle is shaken by the spring, the grease injection device 6 is not separated from the grease container mount 5.

In this state, when grease is to be injected into each grease injecting point of the vehicle, the switch 101 installed in the driver's seat of the vehicle is pressed. The switch 101 is an air tank 8 installed in the vehicle as shown in FIG. ) And the air pump 11 of the grease injection device 6 to open the conduit connected between the air tank 8 and the air inlet 9 of the air pump 11 by pressing this switch. The compressed air of the air tank 8 is introduced into the air inlet (9).

When the compressed air flows into the air inlet 9 of the air pump 11 as described above, the piston 21 inside the air pump 11 by the compressed air introduced into the air pump 11 is widely used and known. The pumping operation is continuously performed while the lifting and lowering operation is repeatedly performed. The grease 100 inside the grease container 1 is installed downward under the air pump 11 in accordance with the known pumping operation of the air pump 11. A suction force is generated in the suction pipe 14 inserted into the suction pipe 14, and the grease contained in the grease container 1 is sucked into the suction pipe 14 and discharged into the supply pipe 2 through the grease discharge port 10 of the air pump 11.

When the grease is discharged to the supply pipe 2 as described above, the grease is supplied to the distributor 4 connected to the plurality of oil supply pipes 3 connected to the plurality of grease feed points. The grease is supplied to the grease feed point through the oil supply pipe (3) of the fuel cell, and when another distributor (4) is connected to the connector pipe (17), another oil is supplied through another distributor (4) as above. Through a plurality of oil supply pipes (3) to supply the grease to another grease feed point.

After the lubrication is completed to a plurality of fuel points as described above is recovered to the recovery port 13 of the grease barrel lid (7) through the recovery pipe 18 to enter into the interior of the grease container (1) to recover. The sensor 19 is installed in the middle of the grease to detect the passage of grease when the grease passes through the return pipe 18 in which the sensor 19 is installed, the sensor 19 is sitting in the driver's seat of the vehicle. When the driver releases the pressing action of the switch 101, the driver stops the injection of compressed air from the air tank 8 to the air pump 11 of the grease injection device 6. The Greek oil stops.

Looking at the pumping action in the air pump 11 from above with reference to Figures 2 and 3, the air tank 8 through the air inlet (9) installed on one side of the air pump body 20 as shown in FIG. When the compressed air supplied from the air flows into the space 24, the opening and closing hole 34 opens the upper hole connected to the upper hole 26, and the intermediate hole and the lower hole 28 connected to the middle air hole 27 and When the connected lower hole is blocked, the compressed air flows into the upper hole 26.

As the compressed air flows into the upper hole 26 as above, the compressed air flows into the “a” space below the piston 21 in the cylinder tube 35 and pushes the piston 21 upwards to perform three actions. Will be done together.

First, when the piston 21 is moved upward, the piston rod 22 below the piston 21 also rises, and the lifting rod 30 installed to be connected to the lower side of the piston rod 22 also rises. In addition, the lower rod 52 installed below the elevating rod 30 also lifts up the grease contained in the grease container 1 while rising as shown in FIG. 3.

The second action is that when the piston 21 ascends, the piston rod 22, the lifting rod 30, and the lower rod 52, which are connected to the lower side, are raised and the space 24 is raised. In addition, the selector 32 installed in the elevating rod 30 in the ascends together, and the opening and closing hole 34 inserted into the moving groove 31 of one side of the select 32 is raised together, and the opening and closing hole 34 is raised. The upper and middle holes of the select plate 33 are blocked, and only the lower hole is opened to allow compressed air to enter the lower hole.

And the third action, the air in the "b" space above the piston 21 in the cylinder tube 35 when the piston 21 ascends the circulation pipe 36 through the upper outlet of the cylinder tube 35 Air exiting to the circulation pipe 36 is introduced into the lower hole 28 to which the lower end of the circulation pipe 36 is connected, and through the connection groove connecting groove 34a of the opening and closing hole 34, It is discharged to the outside through the air hole 27 to allow the piston 21 to rise normally.

As the piston 21 moves up and performs the three actions simultaneously, the position of the select 32 is changed in the second action so that the compressed air flows out of the compressed air into the upper hole 26. Compressed air exiting into the lower hole 28 as it is changed to exit (28) is introduced into the upper "b" space of the cylinder tube 35 through the circulation pipe 36 to push the piston 21 downward Get off.

As above, even when the piston 21 is pushed downward, the three actions are made at the same time, the action is made in the opposite direction as when the piston 21 is raised.

When the piston 21 descends, the first action is that the lifting rod 30 connected in line with the piston rod 22 at the bottom of the piston 21 and the lower rod 52 shown in FIG. 3 descend.

And, the second action is made when the piston 21 is lowered, when the piston 21 is lowered, the select 32 installed on the lifting rod 30 in the space 24 is also lowered together of the select 32 The opening and closing hole 34 inserted into one side moving groove 31 is lowered together, and the opening and closing hole 34 is lowered to block the middle hole and the lower hole of the select plate 33 and to open only the upper hole to the upper hole. To get compressed air back.

And the third function is achieved when the piston 21 is lowered, the air in the "a" space of the lower portion of the piston 21 in the cylinder tube 35 when the piston 21 is lowered to the upper hole 26 It is to be discharged to the outside through the air hole 27 in the middle through the connecting groove connecting groove 34a of the opening and closing hole 34 so that the piston 21 can be normally lowered.

As described above, the inflow direction of the compressed air supplied from the air tank 8 is repeatedly changed, and at the same time, the lower rod in the suction pipe 14 contained in the grease in the grease container 1 as the piston 21 continues to move up and down. 52 is repeatedly raised and lowered to suck the grease to be discharged to the grease outlet 10 of the air pump body 20.

It is necessary to look at the working relationship of the lower rod 52 from above. When the lower rod 52 is raised, the lower disk 49 of the rod 50 installed at the lower end of the lower rod 52 is lifted up and is contained in grease. The grease suction hole 38 sucks the grease, and the sucked grease flows into the lower inlet 42 of the backflow prevention tube 48 through the space above the disk 49.

As described above, the grease introduced into the inlet 42 of the backflow prevention tube 48 is pushed up the ball 46 in the working space 45 while going up to the inlet hole 44, so that the ball 46 is pushed up. The grease outlet flows into the lower space 10a of the air pump body 20 through the working space 45 and the outlet 43 of the upper part of the ball 46 through the space between the both sides and the working space 45 and the gap. Discharged to (10).

At this time, the packing 37 installed at the upper end of the lower space 10a flows into the space 24 through the vertical hole 29 in which the grease raised to the lower space 10a moves up and down. The packing 51 installed on the outside of the backflow prevention tube 48 prevents the grease on the top and bottom of the packing 51 from moving up and down from the outside of the backflow prevention tube 48. It is to be prevented to rise upward only through the backflow prevention pipe (48).

As described above, after the lower rod 52 is raised to suck up the grease to be discharged to the grease outlet 10, the lower rod 52 repeatedly descends, and the lower rod 52 is raised to the lowered mode. The lower rod 52 stops momentarily when converted. At this time, grease is filled between the upper side of the disk 49 and the lower side of the packing 51.

In this state, when the lower rod 52 descends, as much as the disk 49 descends between the upper portion of the disk 49 and the lower portion of the packing 51 due to the lowering of the disk 49, the upper portion of the disk 49 and As the pressure in the space between the lower parts of the packing 51 is lowered, the spring 47 elastically presses the ball 46 downward in the backflow prevention tube 48 so that the ball 46 blocks the inlet hole 44 so that the grease moves upward. It will prevent you from coming up. The non-return tube 48 serves as a check valve.

Therefore, when the lower rod 52 repeatedly moves up and down, the grease is sucked only when the lower rod 52 ascends, and when the lower rod 52 descends, the backflow prevention tube 48 functions as a check valve to prevent the disk 49 from being lowered. ) The grease, which is filled between the upper side and the lower side of the packing 51, prevents the grease from rising above the non-return tube 48 and continuously supplies the grease to the grease outlet 10.

And, as shown in FIG. 3, the lower rod 52 is provided with a long nut 40 and a screw rod 41 in a threaded manner to loosen the long nut 40 and the screw rod 41 and tighten the lower rod. (52) It is possible to adjust the installation position of the rod 50, the lower disk 49 is installed up and down.

The present invention can supply grease to lubrication parts of various industrial machines such as presses and conveyors as well as supply grease to lubrication parts of automobiles.
