Description

Liner and clamp with fitting and deviding apparatus of heat connecting machine for plastic pipe}

The present invention relates to a liner and a clamp of a resin tube heat fusion apparatus provided with detachable means for fixing the resin liner to the clamps of the heat welder, and more particularly, to mount the liner to the clamps of the heat welder or The present invention relates to a liner and a clamp of a resin tube heat fusion device equipped with a detachable means for detaching and mounting without special tools.

Conventional heat welding machine for connecting a synthetic resin pipe laminated a liner to match the diameter of the synthetic resin pipe inside the plurality of clamps, as described in the Utility Model Registration No. 20-0170660, and fixed to the liner and the clamp to connect the synthetic resin pipe connection Fused to connect the synthetic resin pipe.

1 is a perspective view for simplifying the process of mounting the conventional liner to the clamp of the heat welder.

1 is shown in Utility Model Registration No. 20-0170660, through-holes 25 having a thread perpendicular to the contact surface of the clamp 4 and the liner 20 are formed, and in the through-hole 25 The liner 20 is coupled to the clamp 4 by engaging the screw. In addition, the separation of the liner 20 may be made by separating the screw from the through-hole.

However, since the use of the screw to mount the liner 20 on the clamp 4 in this way requires a tool that needs to rotate the screw, it is very difficult and difficult to work in consideration of the fact that the place where the heat fusion machine is used is narrow. It takes a lot of time. In addition, the thread formed in the through holes wears out in accordance with the number of times the liner and the clamp are no longer used.

The present invention has been conceived to solve this problem, and an object of the present invention is that the mounting and dismounting of the liner and clamp can be performed without using a screw, so that it can be operated without a special tool, and thread wear formed on the wall of a conventional through hole It provides a liner and a clamp of a synthetic resin heat pipe apparatus equipped with a detachable means to remove the shortening of the life due to.

A feature of the present invention for this purpose is in a liner and clamp of a synthetic resin heat sealer with detachable means for attaching and detaching a liner laminated according to the diameter of the synthetic resin pipe on the clamp of the synthetic resin pipe heat welder: At least one hemispherical groove is formed on the abutment surface of the liner, a bearing insertion groove is formed inwardly from the abutment surface of the clamp of the liner, and the spherical bearing is elastically fixed to the bearing insertion groove by a spring. By this insertion, the bearing is inserted into and fixed to the hemispherical groove when the liner is attached to the clamp.

In the present invention, the hemispherical grooves are formed in an even number, but are preferably formed in left and right symmetry with respect to the center of the clamp in the longitudinal direction.

In another aspect of the present invention, there is provided a liner and a clamp of a resin tube heat fusion machine with detachable means for attaching and detaching a liner laminated according to the diameter of the resin tube on the clamp of the resin tube heat fusion machine. Grooves are formed in the left and right symmetrical position with respect to the central axis of the longitudinal direction of one of the grooves, the insertion groove is formed stepped in the grooves, the insertion groove is elastically supported by a spring and the A snow catching jaw forming one side wall is provided, and the seating surface of the clamp of the liner when the seat is mounted. Inclined jaws are formed to be caught in the grooves.

In addition, in the present invention, it is preferable that the upper surface of the jam catch jaw is continuously inclined such that the central axis side is low and the opposite side is high.

2 is a cross-sectional view for illustrating a first embodiment of the present invention.

2 shows that the hemispherical grooves 401 and 402 are formed on the contact surface of the liner 20 of the clamp 4 to the left of the central axis X in the longitudinal direction of the clamp 4. The right side shows the symmetrically formed one by one. However, the number can be freely designed and can be operated if left and right symmetrical.

The bearing insertion grooves 201 and 202 are formed in the contact surface of the clamp 4 of the liner 20 so as to contact the hemispherical grooves 401 and 402 at the time of mounting. The bearing insertion grooves 201 and 202 are formed in a cylindrical shape from the contact surface of the clamp 4 to the inside, and spring fixing portions 203 and 204 are protruded from the bottom surface thereof. Spherical bearings 205 and 206 are inserted into the bearing insertion grooves 201 and 202, and the bearings 205 and 206 are elastically formed by the springs 207 and 208. It works as One end of the springs 207 and 208 is fixed to the bearings 205 and 206, and the other end is fixed to the holes (not shown) of the spring fixing parts 203 and 204.

3 is a cross-sectional view for describing a series of operating procedures to explain a process of mounting and detaching a liner to a clamp in a first embodiment of the present invention.

FIG. 3A shows a state in which the liners 20 are aligned with the bearings 205 and 206 facing the left and right hemispherical grooves 401 and 402 on the clamp 4. 4B treats the bearing 205 on the left side to the right of the hemispherical groove 401 on the left side. At this time, the right bearing 206 is placed on the right side of the right hemispherical groove 402. FIG. 4C shows a state in which the bearing 205 on the left side is inserted into the hemispherical groove 401 on the left side by applying pressure to the right side of the liner 20, and FIG. 3D illustrates the state in FIG. The right bearing 206 is inserted into the right hemispherical groove 402 to show the state in which the liner 20 is completely attached to the clamp 4.
