Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable insertion tool mainly used for forcibly fitting an insertion leg of a joint to a pipe end of a hard pipe made of synthetic resin.

[0002]

2. Description of the Related Art Forcibly inserting a bamboo shoot-shaped insertion leg of a joint into a hard pipe made of metal or synthetic resin is necessary for plumbing such as city gas, water supply, cooling and heating. Although hard pipes often have an outer diameter of 10 to 15 mm, conventionally, a large-scale machine tool dedicated to piping or general-purpose is used.
Alternatively, the fitting is coated with a liquid that makes the slide smooth and the joint is fitted into the hard pipe.

[0003]

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to develop a fitting tool which is compact and easy to carry and is easy to use.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in accordance with the above-mentioned object, and a tool main body passing through a retractable rod provided with retreating saw teeth, and a handle portion axially supported by the main body to project outward. Lever-type handle, a lever-type handle that pivotally supports the lever-type handle in the main body, engages the retracting sawteeth, and a disengagement operation handle that projects outward, and a fixed pipe bite fixed to the main body. The wearing half piece, the movable pipe biting half piece that is brought into contact with and separated from the release side surface of the half piece, and the handle piece is put along the side surface of the main body at the time of joining, and the advancing / retreating corresponding to the pipe bite by the movable pipe biting half piece. It is characterized by a holder of a pipe joint with an insertion leg provided on the rod, and has an inventive step that can be carried and used easily and lightly.

[0005]

According to the present invention, the movable pipe gripping half piece 20 is fitted into the fixed pipe gripping half piece 17 of the tool main body 1 with the end of the pipe P having a radius slightly larger than the radius of the half piece protruding slightly.
By operating the handle piece 21 so as to almost close to the release surface of the fixed pipe gripping half piece 17, and bring the lever 22 into contact with the side surface of the tool body 1 as shown by the solid line in FIG. When the joint T is fitted to 24 to make the insertion leg Ta correspond to the center of the pipe P and the lever type handle 10 is pushed several times in the direction of the arrow in FIG. Moving lever type handle 10
Each time is pressed, it intermittently meshes with the retracting sawteeth 8 to move the joint T in the direction of the arrow in FIG. 1, and finally the insertion leg Ta is forced to the end of the pipe P as shown in FIG. Insert. In order to change the lever type handle 10 from the state of FIG. 4 to the state of FIG. 1, the disengagement handle 16 is lifted as shown by the chain line in FIG. 2 to disengage the retreat control lever 14 from the engagement with the retreat saw teeth 8. Do it.

[0006]

1 is a side view, FIG. 2 is a partially cutaway side view, FIG. 3 is a front view, and FIG. 4 is a side view showing completion of fitting. It is a figure.

Reference numeral 1 denotes a tool main body, and as shown in FIG. 3, two symmetrical main body cases 2 and 2 are opposed to each other, and a screw 3 is provided.
And a lever-shaped handle 10 is formed below the passage 4 through which the advancing / retreating rod 7 can freely move horizontally.
5 that protrudes the handle part of the
The disengagement operation of is formed with the missing portion 6 projecting the handle.

Reference numeral 7 denotes an L-shaped advancing / retreating rod which is freely passed through the passage 4 of the main body case 1 in both directions.
Has a reverse convex cross-section, and the backward sawtooth 8 on the lower convex surface.
, And the pins 9 are inserted into the rear end portion thereof to prevent them from falling out of the passage 4. 10 is a shaft 1 inside the tool body 1.
A lever type handle pivotally supported by 1 has a handle portion 12 which is wound around a shaft 11 and has one end fixed to the main body 1 and the other end of which is fixed, and which protrudes rearward from the cutout 5.

Further, a retreat control lever 14 that engages the retreating saw teeth 8 with the weight of the engagement release handle 16 at the tip of the lever type handle 10 as shown in FIG. The front part of the shaft 15 is used as the handle 16 for releasing the engagement. An L-shaped seat 18 provided with a fixed pipe biting half piece 17 is attached to the upper surface of the main body 1 with a screw 19.
(Since the outer diameter of the pipe P is not constant, several types of L-shaped seats 18 are prepared so that it can be replaced each time the diameter is different.) Further, the handle piece 2 is attached to and detached from the open side surface of the half piece 17 at the time of joining in FIG.
A movable pipe bite half piece 20 for holding 1 on the side surface of the main body 1 is fixed to the rising portion of the L-shaped seat 18 with a screw 19. (Usually a set with L-shaped seat 18)

When the handle piece 21 of the movable pipe gripping half piece 20 contacts the side surface of the main body case 1 with the side surface of the main body 1 as shown by the solid line in FIG. 22 is supported by a shaft 23.

Said fixed and movable pipe bite halves 17,
The holder 24 of the joint T with the insertion leg Ta is attached to the rising portion of the advancing / retreating rod 7 so as to be replaceable with the set screw 25 so as to correspond to the center of the pipe P bitten by 20.

In this embodiment, the fixed pipe gripping half piece 17 of the tool main body 1 is fitted with the end portion of a hard synthetic resin pipe P of polyethylene or the like having a radius slightly larger than the radius of the half piece so as to project a little, and the movable pipe. The gripping half piece 20 is operated to the lever 22 so as to approach the release surface of the fixed pipe gripping half piece 17 almost in a closed state, and the pressing lever 22 is rocked substantially horizontally as shown by the chain line in FIG. 1 and the solid line in FIG. Press the handle piece 21 and fit the joint T into the holder 24 of the advancing / retreating rod 7 to make the insertion leg Ta correspond to the center of the pipe P, and then push the lever type handle 10 against the spring 13 several times. Each time the control lever 14 swings together about the axis and pushes the lever type handle 10, the control lever 14 intermittently meshes with the retracting saw teeth 8 to move the joint T in the direction of the arrow in FIG. Insert leg T like The writing forcibly to the end of the pipe P.

[0013]

The fitting tool of the present invention comprises a tool body 1 having a retracting sawteeth 8 through which an advancing / retreating rod 7 is passed, and a lever type handle which is pivotally supported by the body 1 and a handle portion 12 is projected to the outside. 10, a retraction control lever 14 pivotally supported on the lever-type handle 10 to engage the retreating saw teeth 8 and an engagement release handle 16 protruding to the outside, and a fixed pipe biting half-piece fixed to the main body 1. 17 and a movable pipe biting half piece 20 that is brought into contact with and separated from the open side surface of the half piece 17 so that the handle piece is put on the side surface of the main body at the time of joining, and the pipe P bite by the movable pipe biting half piece 20 And the holder 24 of the pipe joint T with an insertion leg provided on the advancing / retreating rod 7, and the insertion leg Ta of the joint T is forcibly and easily inserted into the pipe end of a synthetic resin hard pipe P such as polyethylene. It is possible, On retraction control lever 14 when necessary et simple Ki be removed from the retracting sawtooth 8, there is an effect such that carry and use because it palm has type into a narrow working site can be easily.
