Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 , a water supply and sewage PE pipe 1 for construction in this embodiment includes at least two PE pipes 1. A first connecting block 2 is fixed on the outer surface of the left-end PE pipe 1, and a second connecting block 3 is fixed on the outer surface of the right-end PE pipe 1. A fixing mechanism 4 is provided on the first connecting block 2 and the second connecting block 3.

[0023] It should be noted that the fixing mechanism 4 can facilitate the installation or disassembly between the two PE pipes 1, saving the time and energy of the staff, and effectively avoiding the possibility of affecting the installation efficiency of the PE pipe 1 due to the loss of bolts.

[0024] Please refer to Figures 1-3, in order to facilitate the installation or disassembly between the PE pipes 1, the fixing mechanism 4 in this embodiment includes a driving component, an adjusting component is provided on the driving component, and a limiting component is provided on the adjusting component. The driving component includes a rotating rod 401 rotatably connected to the first connecting block 2 and having one end penetrating to the outside of the first connecting block 2. A rotating hole is formed on the upper surface of the first connecting block 2, and a sealing ring is fixed to the inner wall of the rotating hole. The inner wall of the sealing ring fits with the outer surface of the rotating rod 401. A first bevel gear 402 is fixed to the bottom of the rotating rod 401. A second bevel gear 403 is engaged with the lower part of the outer surface of the first bevel gear 402. A rotating handle is fixed to the top of the rotating rod 401, which is convenient for the staff to rotate the rotating rod 401 more conveniently, and then drive the first bevel gear 402 to rotate. The second bevel gear 403 and the center of the first connecting block 2 are on the same vertical line, so that the two worm gears 404 can rotate stably. A worm gear 404 rotatably connected to the front and rear sides of the inner cavity of the first connecting block 2 through a bearing is fixed to the inner wall of the axis of the second bevel gear 403. Worm wheels 405 are engaged with the front and rear sides of the outer surface of the worm gear 404. The rotating rod 401 drives the second bevel gear 403 and the worm wheels 405 to rotate, providing a power source for the movement of the adjusting component.

[0025] Among them, the adjusting component includes two bidirectional screw rods 406 fixed to the inner wall of the axis of the worm wheels 405 and rotatably connected to the upper and lower sides of the inner cavity of the first connecting block 2 through bearings. Two moving blocks 407 are threadedly connected to the outer surface of the bidirectional screw rods 406. Hinge rods 408 are hinged to the opposite sides of the front and rear groups of moving blocks 407. Slide plates 409 penetrating to the outside of the first connecting block 2 are fixed to the opposite sides of the two hinge rods 408. The left and right sides of the slide plates 409 are respectively in sliding fit with the left and right sides of the inner cavity of the first connecting block 2. The moving blocks 407 drive the hinge rods 408 and the slide plates 409 to move, and then drive the position of the limiting blocks 410 to move.

[0026] At the same time, the limiting component includes limiting blocks 410 fixed to the opposite sides of the two slide plates 409. The limiting component further includes two third connecting blocks 411 fixed to the left side of the second connecting block 3. Limiting grooves 412 are formed on the opposite sides of the front and rear two third connecting blocks 411. Moving holes are formed on the front and rear sides of the first connecting block 2. The moving holes are in sliding connection with the limiting blocks 410. The limiting blocks 410 are in sliding connection with the limiting grooves 412. The thread directions of the two bidirectional screw rods 406 are the same. By moving the limiting blocks 410 and adjusting their positional relationship with the limiting grooves 412, the convenient installation or replacement between the PE pipes 1 can be realized.

[0027] It should be noted that through the cooperation of the driving component, the adjusting component and the limiting component, when the staff disassembles, installs and replaces the PE pipes 1, it can be more convenient and fast, further saving time and energy and improving work efficiency.

[0028] The working principle of the above embodiments is as follows:

[0029] When the PE pipe 1 needs to be installed, first move the two PE pipes 1 so that the second connecting block 3 fits with the first connecting block 2. At this time, the opposite sides of the two third connecting blocks 411 are respectively in contact with the front and rear sides of the first connecting block 2. Then, rotate the turning handle to drive the rotating rod 401 and the first bevel gear 402 to rotate, and further drive the second bevel gear 403 and the worm 404 to rotate. Then, drive the two worm wheels 405 engaged with the worm 404 to rotate, and further drive the bidirectional screw rod 406 to rotate, so that the two moving blocks 407 can drive the two hinged rods 408 to move respectively, and further drive the sliding plate 409 to drive the limiting block 410 to move. The sliding plate 409 moves along the left and right sides of the inner cavity of the first connecting block 2, and the limiting block 410 moves along the moving hole until the limiting block 410 moves into the limiting groove 412. At this time, the positions of the limiting block 410 and the limiting groove 412 are fixed, that is, the first connecting block 2 and the second connecting block 3 can be fixed, and further the two PE pipes 1 can be fixed, and the convenient installation of the PE pipe 1 can be realized. It is not necessary for the staff to screw off the bolts one by one, which is more time-saving and labor-saving. Moreover, it can effectively avoid the situation that the installation of the PE pipe 1 is affected due to the loss of bolts in actual operation, indirectly increasing the cost. By operating according to the above principle, the disassembly and replacement of the PE pipe 1 can also be conveniently realized, further improving the work efficiency.
