Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coating pipe peeling tool used for removing a coating from an end portion of a resin coating pipe such as a gas pipe.

[0002]

[Prior art]

 As a stripping tool for a cladding tube, for example, as shown in Japanese Utility Model Laid-Open No. 1-92984, a guide plate that holds the cladding tube is fixed to the main body so that the amount of protrusion can be adjusted, and is held by this guide plate. It is proposed that the tip of the main body is provided with a blade that is elastically ejected toward the clad tube.

By the way, the position at which the coating is cut to peel the cladding tube needs to be changed according to the diameter of the cladding tube. In the case of a large diameter cladding tube, the position away from the end surface of the cladding tube is required. In the case of small diameter cladding, it is necessary to cut at a position close to the end face of the pipe. However, although conventional cladding stripping tools are capable of stripping cladding of various pipe diameters, they are provided with means for indicating an appropriate cutting position according to the pipe diameter. Not. For this reason, there is a problem that the user has to determine the cutting position by a scale or by using another scale.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned conventional problems and enables not only efficient stripping of the cladding tube but also the coating tube which can cut the coating at an appropriate position according to the diameter of the cladding tube. It has been completed to provide a peeling tool.

[0005]

[Means for Solving the Problems]

 The present invention was made to solve the above-mentioned problems, and a guide plate for pulling the cladding tube toward the blade by the force of the spring is attached to the main body with the blade for peeling fixed to the tip, It is characterized in that a scale plate indicating the end face position corresponding to the diameter of the cladding tube is pivotally attached to the side of the blade at the tip of the main body.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. In FIGS. 1 and 2, reference numeral 1 is a vertically long main body, and 2 is a peeling blade fixed inside a slit formed at the tip of the main body 1. The blade 2 is held by a blade holder 3, and the tip of the blade 2 projects slightly from the tip of the blade holder 3 so that only the coating of the coating pipe P can be cut.

The main body 1 has a back cover 4 on the back surface thereof, and a guide plate 5 is attached to a portion between the back cover 4 and the main body 1. As shown in FIG. 2, the guide plate 5 has a flat plate shape with its tip bent in a dogleg shape, and a coating pipe P is applied to this portion so that it can be pulled toward the main body 1 side. Further, the guide plate 5 has a slit 6 as shown in FIG. 3, and a knob bolt 7 is attached to an arbitrary position in the slit 6 by a square nut 8 and a detent nut 9.

Further, since the spring 10 is mounted between the knob bolt 7 and the lower portion of the main body 1, the guide plate 5 always receives a force pulling toward the main body 1 side. However, since the knob bolt 7 penetrates the short slit 11 formed in the case back 4, the knob bolt 7 can move only within the range of the slit 11. As a result, if the knob bolt 7 is tightened to the guide plate 5, the guide plate 5 is pulled by the spring 10 to take the position shown by the solid line in FIG. 2 and pushed up against the spring 10 to the position shown by the imaginary line. It will also be possible. However, the position of the guide plate 5 with respect to the main body 1 can be freely adjusted depending on the position where the knob bolt 7 is tightened in the slit 6 of the guide plate 5.

On the other hand, a scale plate 12 is pivotally attached by a pin 13 to the side of the blade 2 at the tip of the main body 1. The scale plate 12 displays the end face position corresponding to the pipe diameter of the cladding pipe P. For example, FIG. 1 shows that when the sheath pipe P having a pipe diameter of 20 A is peeled off, the pipe end of the cladding pipe P is Is adjusted to the scale of 20 A, the blade 2 is configured to cut the coating on the 20 A coated pipe P at an appropriate position. The scale plate 12 can be normally folded up as shown by the phantom line in FIG.

Reference numeral 14 denotes a pipe diameter display plate attached to the back cover 4 for easily determining the tightening position of the knob bolt 7 with respect to the guide plate 5 described above. That is, since the knob bolt 7 is pulled by the spring 10 and is always at the lower end of the slit 11, loosen the knob bolt 7 and slide the guide plate 5 to set the scale 15 of the guide plate 5 to the display plate 14. If the knob bolt 7 is tightened again at the position corresponding to the pipe diameter, the guide plate 5 can be fixed at the appropriate position corresponding to the pipe diameter. Further, 16 is a spare blade housed in the lower part of the main body 1.

[0011]

[Action]

 In order to use the coating pipe peeling tool of the present invention configured as described above, first, the position of the guide plate 5 is determined according to the pipe diameter of the coating pipe P using the scale of the display plate 14, and Tighten the knob bolt 7 at the position. Further, the scale plate 12 provided on the side of the blade 2 is spread at right angles to the main body 1. In this state, push the knob bolt 7 up with your fingertips, insert the cladding tube P into the inside of the guide plate 5 as shown in FIG. Match the end face position display corresponding to the pipe diameter of the scale plate 12.

Then, when the knob bolt 7 is released, the guide plate 5 is pulled toward the main body 1 side by the force of the spring 10 to bring the coating pipe P into contact with the blade 2 fixed to the main body 1. Then, when the main body 1 is rotated around the coating pipe P, the blade 2 can cut the coating of the coating pipe P at an appropriate position according to the pipe diameter and perform the peeling.

[0013]

[Effect of device]

 As described above, according to the present invention, the coating can be cut at an appropriate position in accordance with the pipe diameter by simply aligning the pipe end of the coating pipe P with the scale of the scale plate. Moreover, in the present invention, contrary to the conventional one, the blade is fixed to the main body, and since the scale plate is attached to this main body, the relative position between the scale plate and the blade is always constant, There is an advantage that the scale plate is easier to use than when the blade is retractable from the main body. Therefore, the present invention has an extremely great practical value as a stripping tool for a cladding tube that solves the conventional problems.
