In general, high density polyethylene (HDPE) is a non-toxic eco-friendly plastic that does not detect environmental hormones. It has excellent hardness, mechanical strength, heat resistance and cold resistance and is light in weight. , And is widely used as a transfer pipe for sewage and gutters. Such HDPE pipes are required to connect a plurality of pipes in accordance with their application characteristics, and there are connection methods such as water-tight sockets (use of joint pipes), heat welding, and electric fusion welding, and double heat welding is mainly used.

In the heat fusion method, the bonding portions of two HDPE tubes are bonded to each other, and then the mother substrate itself is melted and connected by a constant pressure. In this case, due to the nature of the HDPE pipe, a bead of a certain thickness is formed inside and outside the joint of the HDPE pipe. Internal bead removers that can interfere with fluid flow are well known in Korean Registered Utility Model No. 20-0275400 and Korean Patent No. 10-0844902.

However, in recent years, as the synthetic resin pipe is frequently exposed to the outside, there is a tendency to remove the outer bead in order to improve the aesthetic appearance while preventing the impact from the object from concentrating on the inner bead as well as the outer bead.

As shown in FIGS. 1 and 5, a work hole 11 is formed at the center of the body 10 in a vertical direction.

The rear surface of the work hole 11 forms an inclined surface 12 inclined at a predetermined angle from the lower end of the work hole 11 toward the upper end. 5, the inclined surface 12 is formed as a passage for guiding the external bead B cut by the planar blade 20, which will be described later, coupled to the lower end of the inclined surface 12 to the outside of the body 10 Is used.

In addition, a recessed support groove 13 is formed in the upper end surface of the work hole 11 in the width direction. Here, the width direction is a direction perpendicular to the longitudinal direction of the body 10, and the width direction is the same concept as described above. The ratchet portion 30 can be stably mounted on the work hole 11 due to the support groove 13.

In the present invention, the work hole 11 may be formed parallel to one side of the work hole 11, and may have a long groove 15 formed in the longitudinal direction to overlap a part thereof. The groove 15 is for accommodating a ratchet wheel 31 of the ratchet part 30 received in the work hole 11 and a pawl 32 for operating the ratchet wheel 31. The ratchet wheel 31 of the ratchet part 30 is preferably received in the work hole 11 and the pawl 32 is received in the groove 15. [

When the grooves 15 are formed on the side of the work hole 11 as described above, the support grooves 13 are formed in the width direction across the upper end surfaces of the work holes 11 and the grooves 15, do.

A spiral groove 14 is formed on the side surface of the body 10.

The helical groove portion 14 may be formed on the front or rear side of the work hole 11, or on one side or both sides of the side wall. In the preferred embodiment of the present invention, spiral groove portions 14 are formed on both sides of the side rear.

The planar blade 20 is provided at the lower end of the inclined surface 12 of the work hole 11 formed as described above.

The planar blade 20 is for smoothly cutting the outer bead B of the pipe P entering the work hole 11 and is detachably attachable to the lower end of the inclined surface 12 through a coupling screw 23 As shown in FIG. 5, a cutting portion 21 having an inclination angle coincident with an inclination angle extension line of the inclined surface 12 is formed at the lower end.

1 and 3, the planar blade 20 is formed to have the same length as the width direction of the body 10, and the cutting portion 21 is also formed in the width direction of the work hole 11 The planar blade 20 is formed at the center of the planar blade 20 in the same length. With this configuration, the coupling surface 22, which is a sufficient space for fastening the coupling screw 23 to both sides of the planar blade 20, is secured.

A through hole 16 may be formed in a longitudinal direction of the body 10 on either or both sides of the front and rear portions of the body 10. Preferably, front and rear through-holes 16 are formed on both sides of the body 10 along the longitudinal direction in front and rear directions.

The rear through-hole 16 of the front and rear through-holes 16 is formed to extend out of the operation hole 11 because the inclined end of the operation hole 11 is formed to be long toward the rear, .

Each of the front and rear through holes 16 formed as described above is provided with a pair of pipe fixing portions 16a and 16b capable of holding and fixing the pipe P located on the bottom surface of the operation hole 11 of the body 10 60 are installed.

The pipe fixing part 60 includes a pipe fixing part 62 for fixing the pipe P at the lower end of the through hole 16 and a pipe fixing part 62 integrally joined to the pipe fixing part 62, And a fixing knob 61 screwed to the fixing screw 64 to fix the pipe fixing member 62 to the body 10. Preferably, the fixing handle 61 is of a sufficient size that the operator can push or pull the body 10 along the pipe P while holding the fixing knob 61 under pressure.

In addition, a protruding end 63 may be provided along the longitudinal direction at the center of the upper surface of the pipe fixing piece 62. A guide groove 17 corresponding to the protruding end 63 is formed on the bottom surface of the body 10 when the protruding end 63 is provided on the upper surface of the pipe fixing member 62. The guide groove 17 is formed on the bottom surface of the body 10 so as to extend from one end to the other along the longitudinal direction in the front-rear direction.

The cutting edge 24 of the initial planar blade 20 is inserted into the outer bead B formed in the pipe P and is inserted into the rear end surface of the body 10 so as to be ready for cutting. The rear support end 70 can be further coupled to prevent damage to the body 10 when it is pressed against the impact tool,

The ratchet portion 30 is for introducing the external bead B formed in the pipe P toward the planar blade 20 and is composed of a ratchet wheel 31, a pawl 32 and a rotary shaft 33 .

As shown in FIG. 5, the ratchet wheel 31 is a toothed wheel that rotates only in the clockwise direction due to the reciprocating motion of the pawl 32 to transmit movement force. The teeth of the ratchet wheel 31 moving in the clockwise direction are brought into contact with the surface of the outer bead B and are rotated by the operation of the pawl 32 as shown in the figure, The planar blade 20 disposed close to the lower portion cuts the outer bead B while moving along the pipe P. [ At this time, the cut outer bead B naturally moves to the upper end of the body 10 along the inclined surface 12 of the body 10 having the same inclination as the cutting edge 21 of the planar blade 20, 10).

The ratchet 30 may be received in the work hole 11 by a ratchet wheel 31 and a pawl 32. The ratchet wheel 31 may be received in the work hole 11, (11), and the pawls (32) can be received in the grooves (15).

The ratchet wheel 31 and the pawl 32 are connected in a line and the rotary shaft 33 having the shaft helical groove portion 34 at its end is seated in the support groove 13. At this time, the ratchet wheel 31 of the ratchet part 30, which is seated in the support groove 13, contacts the planar blade 20 to prevent the planar blade 20 from being damaged. Therefore, the size of the ratchet wheel 31 is such that it can transmit the movement force to the outer bead B without contacting the planar blade 20.

The ratchet part 30 configured as described above is selectively accommodated in the operation hole 11 by the rotation of the connecting bar 40. [

The through hole 41 formed at one end of the connection bar 40 has a shaft spiral groove portion 34 formed at the end of the rotation shaft 33 of the ratchet portion 30, And the through hole 41 formed at the other end portion is coupled to the helical groove portion 14 of the body 10 by a fixing bolt 50 rotatably. Therefore, the ratchet portion 30 can be selectively received in or removed from the work hole 11 with the other end of the connecting bar 40 coupled to the body 10 as a central axis.

4, the ratchet portion 30 is detached from the work hole 11 at the start of the work so that the work hole 11 The position of the outer bead B disposed at the lower end of the body 10 can be accurately confirmed.

In addition, when the work is started, the body 10 is held toward the outer bead B, and the cutter 21 must be strongly pushed by an artificial force or a force must be applied by a hammer or the like. At this time, if the ratchet part 30 remains in the state of being accommodated in the work hole 11, the cutting part 21 may not penetrate deeply into the outer bead B due to the interference of the ratchet wheel 31. It is a matter of course that the cutting portion 21 not penetrating deeply into the outer bead B can not effectively remove the outer bead B. [ 4, when the ratchet part 30 is disengaged from the work hole 11 as shown in FIG. 4, the cutting part 21 can be strongly and deeply inserted into the outer bead B, so that the effect of removing the outer bead B .

In addition, when the work is started, in parallel with the disengagement of the ratchet part 30 from the work hole 11, the cutting part 21 is moved in the state in which the pipe fixing part 60 is pushed toward both ends of the body 10 And is inserted deeply into the outer bead (B). Then the pipe fixing piece 62 is adjusted to fit the pipe P disposed at the lower end of the body 10 and is firmly fixed to the body 10 with the fixing knob 61. As shown in FIG. 4, when the pawl 32 of the ratchet part 30 reciprocates right and left, the ratchet wheel 31 moves along the pipe P while holding the outer bead B and moving forward. The cut portion 21 embedded in the outer bead B also cuts the outer bead B as the ratchet wheel 31 advances and the cut outer bead B cuts the rear bevel B of the work hole 11 As shown in Fig. In this process, when the operator grips the fixing tab 61 of the pipe fixing portion 60 and applies pressure, the worker can advance more effectively and the effect of removing the external bead B is doubled.
