Conventional technology and its problems Conventionally, as a construction tool that uses both an extrusion gun and a workpiece to be extruded with a flexible extrusion tube as described above, the extrusion gun has a full-tube loading chamber and a front-loading cylinder. It is known that the structure for extruding the object to be extruded is a kind of extrusion pump, in which the extrusion actuating body consists of a piston inserted into the cylinder. With such a construction tool, it is necessary to remove the cap at the tip of the extrusion gun and load the tube containing the material to be extruded into the loading chamber of the extrusion gun, and to take out the used tube, the cap must be removed and the tube There was a problem that loading and unloading was not easy.

The main purpose of this invention is to load the extrusion tube,
It is an object of the present invention to provide a tool for filling or applying a liquid or paste-like material such as the above-mentioned sealant, caulking material, adhesive, etc., which can be easily taken out.

Means for Solving the Problems The above object of the present invention is achieved by a tool for filling or applying a liquid or paste-like material such as a sealant, caulking material, adhesive, etc., as configured below.

An extrusion gun in which an extrusion actuating body is gradually advanced forward through a loading chamber for an object to be extruded through an increment feeding mechanism by repeated operation of a trigger-type lever, and the extrusion gun is loaded into the loading chamber of the extrusion gun and moves forward. A flexible extruded tube filled with a liquid or paste material such as a sealant, caulking material, or adhesive is included as a component,
The extrusion tube is provided with a nose for extruding the contents forwardly from the loading chamber at its tip, and the loading chamber is of an upward loading type with an open upper side, and the extrusion actuating body of the extrusion gun is operated from above. A tool for filling or applying liquid or paste-like substances such as sealants, caulking materials, adhesives, etc., which consists of an ironing-type squeegee under pressure.

Embodiments Hereinafter, the present invention will be described with reference to drawings showing embodiments of the present invention.

In the figure, reference numeral 1 indicates an extrusion gun, and the extrusion gun 1 has an extrusion actuating body 3 that is fixed to the tip of a rod 2 and is made of an iron-type squeegee under pressure from above. By repeatedly tightening and releasing the trigger type lever 4, the object is gradually advanced forward in the object loading chamber 6 through the increment feeding mechanism 5. That is, in the illustrated embodiment, when the trigger type lever 4 repeatedly swings back and forth about the pin 7 as a result of the repeated operation, the perforated plate serving as the notching feed mechanism, in which the perforated hole 9 is loosely fitted in the rod 2, moves to the lever. One end side is pushed forward by the fixed push rod 8 on the rod 4, and the whole is rotated in the clockwise direction in FIG. 1st of 4
By rotating in the counterclockwise direction in the figure, the notch feed mechanism 5 is pushed forward, and the extrusion actuating body 3 is advanced together with the rod 2. When the trigger-type lever 4 is released, the tick feed mechanism 5 is pushed by the compression spring 10 and returns to its original position.

As shown in FIG. 1, the loading chamber 6 is of an upper open type, and the following extrusion tube 16 is inserted from the upper opening.
It is an upward loading type.

The squeegee, which is the extrusion operating body 3, has a spherical shape. The spherical shape may be any of a complete sphere (Fig. 1), a hemisphere (Fig. 2), and a 4/1 sphere (Fig. 3). Furthermore, in the case of a fully spherical shape, the squeegee that is the extrusion operating body 3 may be of a roller type that can roll along the axis of the loading chamber 6. The front end of the loading chamber 6 has a shape that matches the shape of the extrusion operating body 3.

The loading chamber 6 of the extrusion gun 1 is preferably of a type that prevents the extrusion operation body 3 from floating in order to improve the action of the extrusion operation body 3. The lifting of the extrusion actuating body 3 can be prevented by appropriate means, for example, by forming the loading chamber 6 in a semi-cylindrical shape that embraces the lower half of the entire spherical or hemispherical squeegee, or by forming the loading chamber 6 into the loading chamber 6. This may be achieved by providing a restraining member (not shown) extending in the longitudinal direction.

11 is a grip 12 of the extrusion gun 1 on one end side.
This detent is a perforated plate type that is swingably supported back and forth by a support plate 13 extending rearward from the detent 1.
1 has its bore 14 loosely fitted into the rod 2, and is pushed backward by the compression spring 15 using the support by the support plate 13 as a fulcrum, so that the bore 14 is loosely fitted into the rod 2.
The edge frictionally engages the rod 2 and detents the rod 2. By pushing the detent 11 forward, the frictional engagement is released and the rod 2 can be pulled back.

Reference numeral 16 denotes a flexible extrusion tube filled with a liquid or paste-like substance such as a sealant, caulking material, or adhesive, which is loaded into the loading chamber 6 of the extrusion gun 1 from above, and the extrusion tube 16 has a tip end for extruding the contents. Forward protruding nose 1
7, and the loading chamber 6 of the extrusion gun 1 has an opening 18 which allows the nose 17 to protrude forward. The extrusion tube 16 is attached to the loading chamber 6 and is prevented from moving forward. For example, the front wall 1 of the loading chamber 6 may be prevented from moving forward.
This can be done by hitting the neck 20 of the extruded tube 9. Nose 17 of extruded tube 16
may be detachably attached to the extruded tube body, or may be of a fixed type. Further, the tip of the nose 17 may be open in advance, or the tip may be cut off and opened before use.

An eye plate-like tongue piece 21 is formed at the rear end of the extruded tube 16 (FIG. 4), and the tongue piece 21 is inserted into the hole 22 of the tongue piece 21 with a pin (not shown) in the pin hole (not shown) at the bottom of the loading chamber 6. (not shown). A long lug 23 shaped like an eye plate is attached to the rear end of the extruded tube 16.
(FIG. 5), and the lug 23 is connected to the loading chamber 6 through a slit (not shown) bored at the bottom of the loading chamber 6.
The lug 23 is pulled out to the lower surface, and the lug 23 is fixed with a pin (not shown) in its hole 24 to a pin hole (not shown) in the bottom of the loading chamber 6.

The extruded tube 16 may be of the closed rear end type (FIG. 1) or of the open rear end type sealed by suitable sealing means. As such an extruded tube 16 with an open rear end, the structure illustrated in FIG. 6 can be applied. In this example, the open rear end of the extruded tube 16 is bent in two to form a cylindrical clip 27 with a split groove 25 extending along the axis on a part of the circumference, and a core rod 26 extending along the axis in the center. It is designed to be clamped and sealed. When the split groove 25 of the cylindrical clip 27 is applied to the rear end of the extruded tube 16 which is bent in two, and the cylindrical clip 27 is pushed into the rear end of the two-fold, With the core rod 26 pushed into the loop-shaped portion 28 resulting from the bending, the rear end of the bi-folded portion is inserted into the split groove 2.
5 interjects. When such an open extruded tube is used up and becomes empty, it can be filled with liquid or paste and reused.

In the illustrated embodiment of the invention, a flexible extrusion tube 1 is loaded into a loading chamber 6 of an extrusion gun 1.
6, the extrusion actuating body 3 is gradually advanced forward in the loading chamber 6 through the increment feeding mechanism 5 and the rod 2 by repeated tightening and releasing operations of the trigger type lever 4. As it is squeezed under pressure from above, the liquid or paste-like material inside is pushed out from the nose 17 that projects forward from the loading chamber 6 at the tip, filling the workpiece with the liquid or paste-like material. Alternatively, it can be applied by coating.

That is, in the present invention, the liquid or paste-like material in the extrusion tube 16 is moved forward by the extrusion actuating body 3 made of a squeegee under pressure from above the tube 16, without using the pumping action of a cylinder and piston as in the conventional case. It can be extruded by squeezing it out.

Effects of the Invention As described above, the present invention is used as an extrusion actuator for extruding a liquid or paste-like substance in an extrusion tube filled in the loading chamber of an extrusion gun, under a condition in which the extrusion tube is pressed from above. Since the structure is equipped with a squeeze-type squeegee, the loading chamber of the extrusion gun is an upward-filling type with an open upper side, and the liquid in the extrusion tube by the extrusion actuator is or ensure extrusion of pastes. Thus, according to the present invention, by applying the above-mentioned upper open type loading chamber, the extrusion gun and the extruded object containing the flexible extrusion tube described at the beginning can be easily loaded and unloaded from the upper opening of the extrusion gun. It is possible to provide a tool for filling or applying a liquid or paste-like material such as a sealant, caulking material, or adhesive to be used together with a construction material.

In addition, with the present invention, the operating status of the extrusion actuating body and the degree of reduction of the contents of the extrusion tube in the loading chamber can be visually confirmed from the upper opening of the loading chamber, and the application tool can be used for the intended purpose.
