In FIG. 1, reference numeral 1 is a main body case for accommodating a DC motor 2, and 3 is one grip portion that also functions as a battery storage case for accommodating a detachable and rechargeable battery 4, and is formed integrally with the main body case 1. There is. As shown in FIG. 2, the shape of the grip portion 3 is divided into a front half 3a and a rear half 3b, and the battery 4 is housed in the internal space 3c. The grip portion 3 is formed with a large number of non-slip grooves 3d at a portion on which a finger (not shown) of the operator's right hand contacts, for example. Reference numeral 5 is a switch operated by the index finger of the right hand, and is wired so that when the switch 5 is pushed in, the DC motor 2 starts to rotate.

The pinion 6 fixed to the upward output shaft of the DC motor 2 meshes with the gear 7 rotatably supported by the bearing of the main body case 1, and the eccentric pin 8 protruding upward from the upper surface of the gear 7 is Sliding in a long groove-shaped recess 9a extending in the direction perpendicular to the paper surface of Fig. 1 provided on the lower surface of a block 9b fixed to the lower surface of the right end of a horizontal reciprocating rod 9 slidably supported by a bearing of the main body case 1. It is rotatably fitted. The rotation of the DC motor 2 is transmitted to the reciprocating rod 9 via the pinion 6, the gear 7, the eccentric pin 8, and the block 9b, and the reciprocating rod 9 has a stroke of twice the eccentric amount L of the eccentric pin 8 (2L). Go back and forth in the A and B directions.

Reference numeral 10 is a piston fixed concentrically to the left end of the reciprocating rod 9, and 11 is a bearing 11b and a cylinder 11c into which the piston 10 fits, and a downward-opening conical hole between the bearing 11b and the cylinder 11c. A pump body having a suction portion 11a formed therein, 12 is a bellows type cartridge in which an opening 12a at the upper end is screwed into a slightly larger diameter screw hole 11d (connection portion D) immediately below the suction portion 11a of the pump body 11, 13 is a bellows The other grip portion (storage case) that also serves as a case for storing the cartridge 12, and the grip portion 13 is provided with anti-slip grooves 13a of various shapes to prevent slipping when gripped by the left hand, for example. You can

Since the bellows type cartridge 12 receives an upward elastic force from the compression spring 13b via the spring receiving disk 20 on the lower surface of the bottom portion 12b, the grease inside the bellows type cartridge 12 is fully compressed. Can be continuously supplied to the suction portion 11a and the cylinder 11c. One end of a chain 22 is connected to a boss 21 that is integrally provided at the center of the lower surface of the disc 20, and the chain 22 passes through a central hole 23 of the cap 13d that also serves as a spring receiver, and the tip is larger than the hole 23. It has a ring 24 of diameter.

Reference numeral 14 is an outlet check valve, 15 is a short pipe, and 16 is a mouthpiece which is held in contact with a grease nipple (not shown). Further, 25 and 26 are joints that connect the main body case 1 and the pump main body 11, 27 is a tightening bolt having a hole through which the piston 10 passes, and 28 is operated in the direction of arrow C to lock the switch 5 (inoperable). The lock lever and 29 are battery covers. The one gripping portion 3 and the other gripping portion 13 are respectively placed on the right and left palms, and are set to have a size that can be grasped by fingers.

To press the grease into the rotary shaft or the sliding part, first grasp the grips 3, 13 with the right hand and the left hand, press the mouthpiece 16 against the target grease nipple, and switch with the index finger of the right hand. When 5 is pushed in, the DC motor 2 is activated and the piston 10 reciprocates together with the reciprocating rod 9 in the directions of arrows A and B. Since the suction portion 11a and the cylinder 11c are filled with grease pressurized by the elasticity of the spring 13b, when the piston 10 moves in the direction of arrow A from the rear retracted position in FIG. 1, the piston 10 moves to the cylinder 11c. The grease in the cylinder 11c is pressurized from the time when the fitting is started, and the outlet check valve 14 is pushed open to be fed into the short pipe 15, and the grease is forced into the grease nipple from the mouthpiece 16. By the time the piston 10 returns to the retracted position shown in FIG. 1, the pressurized grease is replenished into the cylinder 11c.

FIG. 3 shows a portable viscous fluid supply pump according to the present invention when a hand-filled oil cylinder 30 is adopted. That is, instead of the threaded portion 11e (fixed portion E) of the pump main body 11 shown in FIG. 1, the storage case 13 (grasping portion) detachably attached by the threaded portion 13e was attached to the hand-filled oil cylinder 30. It shows the state. A piston 31 fitted in an oil cylinder 30 in an oil-tight manner, a spring 33 for urging the piston 31 in the direction of the suction portion 11a (direction of arrow 34, for example, upward), and one end (upper end) of the piston 31 locked. A rod 32 that projects the other (lower end) out of the oil cylinder 30 is inserted. A handle 35 is screwed to the lower end of the rod 32. The rod 32 is provided with a groove portion 32a, which is adapted to be engaged with an engaging portion 30a (FIG. 4) provided at the bottom of the oil cylinder 30.

When a viscous fluid such as grease is hand-packed in the oil cylinder 30 from a pail or the like, the handle 35 is pulled down against the spring 33, and the groove 32a of the rod 32 is hooked on the locking portion 30a. The oil cylinder 30 is filled with a spatula, a trowel, or a pump.

Reference numeral 36 denotes an intermediate member (attachment) in which a cap 30b of the oil cylinder 30 is detachably screwed into a screw hole 36c in the lower half portion, and the storage case 13 of FIG. The same screw portion 36a as the screw portion 13e is screwed and screwed to the screw portion 11e (fixed portion E). The intermediate member 36 has a hole 36b in the center thereof, which connects the suction portion 11a of the pump body 11 and the inner portion of the oil cylinder 30. 37 and 38 are oiltight packings. The means for attaching / detaching the storage case 13 and the intermediate member 36 to / from the pump body 11 (fixed portion E) is not limited to the above-mentioned screw, and is pressed by, for example, a combination of a radial pin and a notched taper groove. It can be turned to the right, turned to the left and pulled out, or structured like a one-touch hose attachment / detachment bracket. The connection part D is also the same.
