Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an injection device for mixing two liquids and discharging the mixture from an injection gun.

With conventional injection devices, when two types of liquids that cannot be mixed and stored together are injected into the same location, one liquid must be injected first, and then the other liquid must be injected, which is very troublesome. It was hot.

In view of the above points, the present invention provides an injection device capable of simultaneously injecting two liquids, and one embodiment thereof will be described below with reference to the drawings.

In FIG. 1, 1a and 1b are a pair of hand pumps, and the suction ports 2 of the hand pumps 1a and 1b are
a, 2b are connected to a first liquid storage tank 4a and a second liquid storage tank 4b, respectively, by communication pipes 3a, 3b made of hoses or the like. Further, the discharge ports 5a, 5b of the hand pumps 1a, 1b are connected to one injection gun 7 through communication pipes 6a, 6b made of hoses or the like.

As shown in detail in FIG. 2, the hand pumps 1a, 1b pump the inside of the casings 10, 11 by the reciprocating motion of a cylindrical operating rod 9a or 9b that can move in and out of the main body 8a or 8b. A diaphragm 12 made of rubber or the like is displaced, thereby operating. The hand pumps 1a, 1b have legs 13a, 1b, as shown in detail in FIGS. 3 and 4.
The lengths of the pumps 3b are different from each other, and one hand pump 1a is located at a higher position than the other hand pump 1b. The hand pumps 1a, 1b are fixed to a base 15 by a plurality of bolts 14 and nuts (not shown) in recesses (not shown) formed in the bottom surface of the base 15. That is, the bolt 14 is attached to a screw hole (not shown) formed in the leg parts 13a, 13b and a through hole (not shown) formed in the base 15 so as to open in the bottom wall of the recessed part. ), the distal end protrudes into the recess, and is threadedly engaged with a nut within the recess. Further, among the through holes drilled in the base 15, the through holes through which the bolts 14 for fixing one hand pump 1a pass are the through holes drilled in the operating rod 9a.
The hand pump 1a is formed in a long hole along the reciprocating direction, and the position of one hand pump 1a can be adjusted slightly along this long hole. The operating rods 9a, 9b are
One end thereof always protrudes outward from the front surface of the main bodies 8a, 8b, and a recessed groove is formed in the one end surface along the vertical direction. 16a, 16
b is a pair of operating rods, and the operating rods 16a, 16
b is connected to the other hand pump 1 by the bolt 17.
Pins 19a, 1 supported by a pair of brackets 18a, 18b fixed to the base 15 in the same way as in b.
9b rotatably supported around the pins 19a and 19b. This operating lever 16a, 16
Plate bodies 20a and 20b that fit into grooves formed in one end surface of the operating rods 9a and 9b are fixed to the plate bodies 20a and 20b.
It is connected to the operating rods 9a and 9b by means of a and 21b. Further, the operating rods 16a and 16b are integrally connected to each other by a connecting rod 22.

Next, the operating procedure will be explained. First, open the handle of the injection gun 7, then open the operating levers 16a, 16.
b is reciprocated around pins 19a and 19b.
As a result, the operating rods 9a, 9b reciprocate and operate the hand pumps 1a, 1b, so the storage tanks 4a, 4
The first liquid and second liquid in b are connected to communication pipes 3a and 3.
b, hand pumps 1a, 1b, and communication pipe 6a,
6b, they each flow into the injection gun 7, merge inside the injection gun 7, and then are discharged. At this time, since the operating rod 9a of one hand pump 1a is at a higher position than the operating rod 9b of the other hand pump 1b, the distance between pins 19 and 21a is
b, 21b, and the reciprocating distance of the operating rod 9a is longer than the reciprocating distance of the operating rod 9b. Therefore, one hand pump 1a has a higher discharge capacity than the other hand pump 1b. becomes larger, so
The mixed liquid of the first liquid and the second liquid discharged from the injection gun 7 contains more of the first liquid than the second liquid. The thickness ratio of the first liquid and the second liquid can be arbitrarily set by appropriately selecting the height of one hand pump 1a.

In this way, the first liquid and the second liquid can be injected simultaneously with extremely simple operations, and one hand pump 1
By appropriately selecting the height of a, the mixing ratio of the first liquid and the second liquid can be set arbitrarily. Note that various combinations of the first liquid and the second liquid can be considered, such as mortar and its curing agent. Further, as in this embodiment, one hand pump 1a is connected to the operating rod 9.
If it is configured to be slightly movable in the reciprocating direction of a, the discharge amount of the first liquid can be finely adjusted.

As explained above, according to the injection device according to the present invention, two liquids stored in separate storage tanks can be simultaneously injected by an extremely simple operation. Furthermore, by appropriately selecting the height of one of the hand pumps, the mixing ratio of the two liquids can be set arbitrarily.
