[0024] The embodiment of the present application discloses a fixing fixture of a plastic pipe electric fusion welding machine, comprising a welding tube tightener 1, wherein the lower part of the welding tube tightener 1 is fixedly connected to a crossbeam frame 11, a side of the crossbeam frame 11 is provided with a limiting hole 10, a plug-in connector 5 is plugged into the limiting hole 10, a column of the plug-in connector 5 is slidably connected to a limiting cylinder 4, an end of the limiting cylinder 4 is fixedly connected to a blocking handle 6, a cylinder of the limiting cylinder 4 is fixedly connected to a connecting handle 3, an end of the connecting handle 3 is fixedly connected to a double-head frame 2, and an adjusting bolt 7 is slidably connected to the hole of the double-head frame 2;

[0025] The plug connector 5 includes: a sliding column 51 and a spring 52. The end of the plug connector 5 is fixedly connected to the end of the sliding column 51. The column body of the sliding column 51 is sleeved with the spring 52. The column body of the sliding column 51 penetrates and is slidably connected to the end of the limiting cylinder 4.

[0026] The sliding column 51 further includes: a sliding ring 511 and a plug column 512. The end of the sliding column 51 is fixedly connected to one side of the sliding ring 511, and the other side of the sliding ring 511 is fixedly connected to the end of the plug column 512. The column body of the sliding column 51 is slidably connected to the end of the limiting cylinder 4.

[0027] The limiting cylinder 4 comprises: a fixing plate 41 and a guide rail 42. The fixing plate 41 is fixedly connected to the end of the limiting cylinder 4. The hole in the middle of the fixing plate 41 is slidably connected to the column of the sliding column 51. The inner wall of the limiting cylinder 4 is fixedly connected to the end of the guide rail 42. The guide rail 42 is slidably connected to the groove of the sliding ring 511.

[0028] The adjusting bolt 7 comprises: a ball handle 71 and a pressure bearing member 72. One end of the adjusting bolt 7 is fixedly connected to the end of the ball handle 71, and the other end of the adjusting bolt 7 is fixedly connected to the end of the pressure bearing member 72. The bolt body of the adjusting bolt 7 is threadedly connected to the end of the double-head frame 2.

[0029] A thread groove 21 is formed at the end of the double-head frame 2 , and the thread groove 21 is threadedly connected to the adjusting bolt 7 .

[0030] Working principle: When using an electric fusion welding machine to weld a PE pipe, first place the welding pipe tightener 1 on the bottom of the pit dug at the construction site. At this time, the bottom of the welding pipe tightener 1 will be tilted due to the rugged bottom of the dug pit. At this time, take out the double-head frame 2, pull the connector 5 by hand, so that the connector 5 drives the sliding column 51 to move, and the sliding column 51 drives the plug-in column 512 to retract into the interior of the limiting cylinder 4. During this process, the sliding ring 511 slides under the restriction of the guide rail 42, and the spring 52 is compressed. Then, the plug-in column 512 is aligned with the limiting hole 10, and then the connector 5 is released. At this time, the compressed spring 52 releases its elastic force, so that the spring 52 drives the sliding ring 511 to reset, so that the plug-in column 512 is inserted into the limiting hole 10, and then the double-head frame 2 is fixed on the crossbeam frame 11, and then the ball handle 71 is turned by hand, so that the ball handle 71 drives the adjusting bolt 7 to rotate, and the adjusting bolt 7 is threadedly connected with the thread groove 21, and the double-head frame 2 is in a stationary state, so by turning the ball handle 71, the adjusting bolt 7 is moved up or down, and the adjusting bolt 7 drives the pressure-bearing member 72 to move, so that the pressure-bearing member 72 is against the rugged bottom surface, thereby adjusting the inclined welding pipe tightener 1 to a horizontal state, and then the pipe to be welded is installed on the welding pipe tightener 1, and an electric fusion welding machine is used for welding.

[0031] By adjusting the action of the plug-in component 5, the double-head frame 2 is fixedly connected to the crossbeam frame 11, and the multiple limiting holes 10 provided on the crossbeam frame 11 can make the position of the double-head frame 2 flexible, and can be installed according to the position required for adjustment of the on-site tunnel. At the same time, multiple double-head frames 2 can be installed to adjust the welding pipe tightener 1. This installation method is more flexible. By rotating the direction of the adjusting bolt 7, the amplitude of the pressure-bearing member 72 squeezing the bottom surface of the tunnel is adjusted, so that the part of the welding pipe tightener 1 below the plane is lifted, so that the welding pipe tightener 1 is kept horizontal as a whole, avoiding the use of an electric fusion welding machine to weld the PE pipe, because the welding pipe tightener 1 is tilted due to the low bottom surface of the tunnel, resulting in the fixed pipeline welding being affected.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
