The plastics piping joint 100 using the hand pushing includes the packing 110, the stopper 120, and the housing 130. The stopper 120 is disposed in connection with one surface of the packing 110 and the housing 130 receives the packing 110 and the stopper 120. Hereinafter, the plastic pipe (P) is referred to as a pipe.

The packing 110 includes a high-elasticity polymer material capable of expanding and contracting such as shrinkage and expansion and serving as a spring, and a high-elasticity elastomer is preferable. In general, the modulus of elasticity of steel is about 201 GPa, and the elasticity of high-elasticity elastomer is 0.7 to 4.0 MPa, which is excellent in mechanical strength and adhesion as well as elasticity.

The stopper 120 and the housing 130 are preferably made of stainless steel containing a high strength carbon steel material and having high strength and excellent corrosion resistance.

FIG. 2 is an enlarged cross-sectional view of a part of the plastic piping joint of FIG. 1. Housing 130 includes a step 131 for contacting the other end of the packing 110 with the end of the pipe P, And is connected to the other end of the stepped hole 131 and the step hole 132 formed to be smaller than the outer diameter of the pipe P so as to guide the movement of the stopper 120, And a tapered surface 133 that narrows in the direction of the inlet /

On both sides or the both sides of the inlet / outlet or the short hole 132, a hole through which the pipe P is joined, separated or inserted is formed.

The housing 130 may further include a foreign matter film 134 which forms the inlet / outlet of the pipe P and prevents foreign matter from entering.

3 is a cross-sectional view showing a foreign matter blocking film according to the present invention, and is a cross-sectional view of a foreign matter film in a width direction of a plastic pipeline P. FIG.

Referring to the sectional view of the plastic piping joint 100 in the longitudinal direction of the piping P of Fig. 1 and the sectional view of the foreign matter blocking film 134 in the width direction of the piping P of Fig. 3, the foreign matter blocking film 134 ) May have a shape of a cylinder or a three-dimensional shape with an opening formed in the longitudinal direction of the pipe (P), and the shape of the center may have a circular shape or a curved surface of an external shape of the pipe (P) .

The packing 110, the stopper 120 and the housing 130 are formed in the longitudinal direction of the pipe P so that the shape of the center of the cylinder or the shape of the three- And the center-opened shape when viewed in the width direction of the plastic-based pipe (P) can have a circular shape, an outer shape of the pipe (P), or a geometric shape-based curved surface for providing airtightness and tensile- have.

The plastic-based pipe joint 100 may have a shape of a cylinder or a cubic shape with a center hole, and can be confirmed through the sectional views of FIGS. 1 to 3 described above.

Fig. 4 is an enlarged cross-sectional view of the packing shown in Fig. 2, in which the inner circumferential surface of the packing 110 is in contact with the outer circumferential surface of the pipe P, Shaped protruding surface 112 for increasing the contact area and increasing the secondary airtightness.

The packing 110 is brought into surface contact with the outer circumferential surface of the pipe P through the surface contact inner circumferential surface 111 to increase the primary airtightness and generate friction with the outer circumferential surface of the pipe P via the M- , The contact area can be widened to enhance the secondary airtightness, so that the fastening of the pipe (P) can be maintained even at an ultrahigh pressure of 100 bar or more.

The outer surface of the packing 110 is a curved surface which is in contact with the tapered surface 133 and narrows in the direction of the inlet and the outlet of the pipe P. The packing 110 is formed by hand- The pipe P is contracted in the direction of the step 131 and the end of the pipe P is in contact with the step 131 so that the pipe P is expanded in the direction of entrance / exit when the fastening is completed.

The packing 110 contracts in the direction in which the pipe P is inserted and returns to the direction opposite to the contraction due to elasticity after the pipe P is inserted and the contact surface with the interpolated pipe P is formed to be wide.

The plastic piping joint 100 effectively absorbs vibrations and shock transmitted to the piping P by forming an M-shaped protruding surface on the inner peripheral surface of the stretchable and highly elastic packing 110, The airtightness can be increased by widening the contact area.

The inner peripheral surface of the stopper 120 may be a curved surface 121 having a W-shaped curve for increasing the tensile stopping force against the outer peripheral surface of the pipe And the outer peripheral surface of the stopper 120 is a curved surface which is in contact with the tapered surface 133 and narrows toward the inlet / outlet direction of the pipe P. [

The stopper 120 is moved in the direction of the step 131 when the packing 110 is contracted by the hand pushing transmitted in the longitudinal direction of the pipe P and the end of the pipe P is in contact with the step 131 The packing 110 is inflated and moved in the direction of the inlet / outlet.

The stopper 120 is expanded by the packing 110 to move in the direction of the inlet / outlet along the tapered surface 133 and is stopped by the urging force of the tapered surface 133 to fix the pipe P. [

The stopper 120 maximizes the surface contact with the elastically deformable head of the pipe P while a large compressive stress is applied to the contact surface of the pipe when the tensile force is applied to move the pipe P away.

The tapered surface 133 prevents the separation of the packing 110 and the stopper 120, and guides the movement of the stopper.

The plastic piping joint 100 is formed in such a manner that the outer peripheral surface of the stopper 120 is brought into close contact with the tapered surface 133 to increase the tensile stopping force and form a curved surface having a W-shaped curve on the inner peripheral surface of the stopper 120, .

The plastic piping joint 100 can strongly fasten the piping P by using the hand pushing without using the tool so that the work efficiency and workability of the user can be improved and the liquid or gas supplied to the piping P Leakage and leakage of the water can be prevented.

The housing 130 may further include a release hole insertion hole (not shown) which is a separate release hole insertion path at the entrance and exit, and the release hole may be a metal of wire type.

The plastic-based piping joint 100 does not require a separate tool when coupling the pipe P, and can be fastened simply by hand pushing and is easily disassembled. The user inserts a separate release port into the release hole insertion hole when the plastic piping joint 100 and the pipe P are disassembled to press the stopper 120 and push the stopper 120 to the inside of the stopper 120, ) Is contracted, a clearance is generated between the plastic-based piping joint 100 and the pipe P, and can be easily separated.
