Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand gun for applying adhesive, which has a two-liquid collecting tool screwed onto the hand gun body, and a mixing nozzle fitted on one side of the collecting tool.

This type of handgun, as shown in Figure 1,
A two-liquid collecting device 2, usually a double pipe, is screwed onto the handgun body 1, and a mixing nozzle 3 is fitted on one side of the collecting device. Among them, the collector 2 is used to separately inject the two liquids sent from the handgun body 1 into the mixing nozzle 3, and its tip is inserted into the tube bodies 22, 22 fitted into the nozzle block 21. It is composed of Each tube 2
2 and 22 are attached to the handgun body 1 with cap nuts 23 and 23, while the nozzle block 21
Since the mixing nozzle 3 is fitted into the tube as described above, the diameter of the tube body 22 is regulated by the inner diameter of the nozzle 3. If you look at this differently,
This means that the amount of adhesive discharged in this type of hand gun is limited by the inner diameter of the tube body 22.
Furthermore, the collecting tool 2 consisting of the tubular body 22 has the disadvantage that, if the tubular body becomes clogged, it takes time to clean it.

The present invention has been made in view of the above circumstances, and is intended to eliminate the above-mentioned disadvantages or drawbacks of the handgun itself, mainly by improving the two-component collector.

In order to achieve the above object, the present invention constitutes a gathering tool using a block as a solid body, and forms a discharge port and an injection port communicating with this separately on the front and back surfaces of the block body, and also forms a discharge port and an injection port communicating with the discharge port on the front and back surfaces of the block body. In addition, an opening communicating with these is formed in the block body,
The opening is normally closed by screwing it in, and the screw can be removed as needed, making it easier to clean and maintain the collector block. The present invention will be explained below based on an illustrated embodiment. Note that the same reference numerals are given to the same components as those in the known example shown in FIG.

The adhesive application hand gun according to the present invention has a second
As shown in the figure, a two-liquid collector 4 made of a lightweight metal block made of, for example, an aluminum alloy is screwed onto a handgun body 1, and a mixing nozzle 3 is fitted on one side of the collector.

The collector 4 has a discharge port 42 formed on the front surface 41a of the block body 41, and injection ports 43, 43 formed on the back surface 41b.

In this example, the discharge port 42 is provided protruding from the block body 41, and its central portion is partitioned by a separator 42a to form two liquid discharge ports 42b, 42b.

The injection ports 43, 43 are connected to the discharge ports 42, 42.
b, 42b and communication holes 44, 44, respectively, and are provided at positions corresponding to the discharge ports 11, 11 of the handgun main body 1. In this way, the discharge port 4
2 and the injection port 43 through the communication hole 44, by appropriately selecting and configuring the diameter of the communication hole 44, it is possible to avoid the restrictions on the amount of adhesive discharged as in conventional double pipes. Inconveniences can be avoided.

Furthermore, one end of the communication hole 44 and the discharge port 42
The other end is formed to communicate from the block body 41 to the outside. To explain this in detail, the communication hole 44
is located on the side surface 41c of the block body 41, and the other end of the discharge port 42 is located on the back surface 41b of the block body 41, respectively.
These openings 42c and 44a are formed to communicate with the outside, and screws 5 and 5 are normally screwed into these openings 42c and 44a. In this way, the opening 42
If the screws 5, 5 are screwed into the holes 44a and 44a, when the through hole 44 becomes clogged, it can be easily cleared by removing the screws 5, 5. It is possible to eliminate clogging, and to facilitate cleaning and maintenance of the collection tool 4 without worrying about the presence of clogging.

In FIG. 2, a bolt 12 is provided protruding from the handgun body 1, and a through hole 45 is formed approximately in the center of the block body 41, so the bolt 12 is inserted into the through hole and the nut 6 is inserted. By fastening at , the collector 4 can be attached to the handgun body 1 very easily.

As explained above, the present invention includes providing a discharge port and an inlet in communication with the block body of a two-liquid collector, and further forming an opening communicating with these, and a screw is screwed into the opening. Because of this structure, cleaning and maintenance of the collecting tool is facilitated, and it is also possible to avoid problems such as restrictions on the amount of adhesive discharged in the conventional method.
