Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 One embodiment provided by this utility model:
[0023] A plastic pipe for easy docking and installation includes a first pipe body 1, with a second pipe body 11 at one end of the first pipe body 1. The ends of the first pipe body 1 and the second pipe body 11 are docked by heat fusion. A guide mechanism is provided on the surface of the first pipe body 1. The guide mechanism includes a positioning ring 2, which is fixedly connected to the surface of the first pipe body 1. A connecting rod 21 is inserted into the surface of the positioning ring 2. A clamping plate 22 is fixedly connected to the surface of the connecting rod 21. A spring plate 23 is fixedly connected to the surface of the clamping plate 22. A connecting rod 24 is fixedly connected to the surface of the spring plate 23. A fixing nut 25 is fixedly connected to the surface of the connecting rod 24. A limit bolt 26 is threaded onto the surface of the fixing nut 25. A connecting bracket 27 is fixedly connected to the surface of the connecting rod 24. A guide ring 28 is fixedly connected to the surface of the connecting bracket 27. The second pipe body 11 is perforated and connected to the surface of the guide ring 28. A limit mechanism is provided on the surface of the second pipe body 11. The docking mechanism includes a fixed rod 3, which is fixedly connected to the surface of the second tube 11. A rotating component 31 is rotatably connected to the surface of the guide ring 28. A limiting ring 32 is fixedly connected to the surface of the rotating component 31. A limiting block 33 is fixedly connected to the surface of the limiting ring 32. A guide block 34 is fixedly connected to the surface of the guide ring 28. A return spring 35 is fixedly connected to the surface of the guide block 34. A limiting rod 36 is fixedly connected to the surface of the return spring 35. The limiting rod 36 is slidably connected to the surface of the guide block 34. This docking mechanism can quickly help the second tube 11 accurately find the horizontality and coaxiality of the first tube 1 for docking, without docking misalignment or tilting, thus improving docking accuracy. It eliminates the need for secondary docking, thereby greatly improving docking efficiency. Furthermore, the limiting mechanism can restrict the position of the second tube 11 after docking, preventing displacement during the hardening and fusion of the ends of the first and second tubes 11, and ensuring the stability of the docking.
[0024] Furthermore, the surface of the positioning ring 2 is provided with multiple sets of limiting holes, which are evenly distributed in a circular shape. Multiple sets of plug-in rods 21 are provided, and multiple sets of plug-in rods 21 are inserted into the limiting holes of the positioning ring 2. The plug-in rods 21, in conjunction with the positioning ring 2, quickly find the installation position of the clamping plate 22, the spring plate 23 and the connecting rod 24 on one side of the first tube body 1. Moreover, the plug-in rods 21 are in the limiting holes of the positioning ring 2, which prevents the clamping plate 22, the spring plate 23 and the connecting rod 24 from moving out of the first tube body 1.
[0025] Furthermore, two sets of clamping plates 22 are provided, and they are arc-shaped. The clamping plates 22 are in contact with the surface of the first tube 1. Two sets of spring plates 23 are provided, and the two sets of spring plates 23 and the connecting rod 24 are perpendicular to each other. The spring plates 23 deform to make the two sets of clamping plates 22 and the surface of the first tube 1 in contact. Under the elastic force of the spring plates 23, the clamping plates 22 are clamped on the surface of the first tube 1, which makes it easy for the clamping plates 22, spring plates 23 and connecting rod 24 to be installed on the surface of the first tube 1.
[0026] Furthermore, a limiting groove is provided on the side of the positioning ring 2, and the limiting bolt 26 is inserted into the limiting groove of the positioning ring 2 through the fixing nut 25. The fixing nut 25 and the limiting bolt 26 restrict the position of the connecting rod 24 and the spring plate 23 on the first tube body 1, thereby ensuring the stability of the position of the connecting bracket 27 and the guide ring 28. The connecting bracket 27 is in the shape of an "L" and the center of the guide ring 28 and the positioning ring 2 are on the same horizontal line. The guide ring 28 is used to guide the docking of the second tube body 11 to avoid tilting and deviation during the docking of the second tube body 11.
[0027] Furthermore, four sets of fixing rods 3 are provided, and one end of the fixing rod 3 is provided with an inclined surface, so that the second tube 11 can be simultaneously connected to the guide ring 28 and the limiting ring 32 through holes. The inner rings of the guide ring 28 and the limiting ring 32 are provided with four sets of rectangular grooves. The fixing rod 3 slides on the rectangular grooves of the guide ring 28 and the limiting ring 32 at the same time. At this time, under the guidance of the guide ring 28, the second tube 11 can accurately perform heat fusion welding with the first tube 1.
[0028] Furthermore, a movable groove is provided on one side of the guide ring 28, and the shape of the movable groove is the same as that of the rotating part 31. The rotating part 31 is generally circular and has a "T" shaped cross section. The rotating part 31 rotates on the movable groove of the guide ring 28, and the limiting ring 32 rotates on one side of the guide ring 28 through the rotating part 31. The limiting ring 32 changes the position of the rectangular groove on the limiting ring 32 by rotating, so that the rectangular groove of the limiting ring 32 and the rectangular groove of the guide ring 28 are misaligned. At this time, the limiting ring 32 can contact and connect on one side of the guide ring 28 and the other side of the inclined surface of the positioning ring 2, preventing the fixing rod 3 from sliding in the opposite direction on the guide ring 28, thereby ensuring the stability of the first tube 1 and the second tube 11 when they are joined and hardened.
[0029] Furthermore, four sets of limiting blocks 33 are provided. Limiting holes are opened on the surface of the limiting blocks 33. The elastic force of the return spring 35 acts on the limiting rod 36. The limiting rod 36 is inserted into the limiting hole of the limiting block 33. The limiting rod 36 restricts the rotation angle of the limiting ring 32 on the guide ring 28 through the limiting block 33. When the limiting rod 36 is not inserted into the limiting hole of the limiting block 33, the rectangular grooves of the limiting ring 32 and the guide ring 28 are misaligned with each other.
[0030] Working principle: The deformation of the spring plate 23 causes the clamping plate 22 to clamp the surface of the first tube 1. Moving the spring plate 23 causes the clamping plate 22 to drive the insertion rod 21 to the limiting hole of the positioning ring 2. The limiting bolt 26 is rotated on the surface of the fixing nut 25, so that the limiting bolt 26 is inserted into the limiting groove on the side of the positioning ring 2. At this time, the positions of the connecting rod 24 and the connecting bracket 27 are restricted to one side of the first tube 1, and the connecting bracket 27 restricts the position of the guide ring 28 at one end of the first tube 1. The second tube 11 is passed through the guide ring 28 to perform heat fusion welding between the second tube 11 and the first tube 1. Under the guidance of the guide ring 28, the second tube 11 can quickly and accurately find the horizontality and coaxiality of the docking with the first tube 1, without docking misalignment or tilting, improving the docking accuracy and eliminating the need for secondary docking, thereby greatly improving the docking efficiency.
[0031] The second tube 11 is simultaneously perforated and connected to the guide ring 28 and the limiting ring 32, and the fixing rod 3 slides on the rectangular groove of the limiting ring 32 and the guide ring 28. When the first tube 1 and the second tube 11 are connected, one end of the inclined surface of the fixing rod 3 is located at the end of the rectangular groove of the guide ring 28. At this time, the limiting rod 36 is moved out of the limiting hole of the limiting block 33, and the limiting ring 32 is rotated on the guide ring 28 by the rotating component 31, so that the limiting ring 32 and the limiting hole of the guide ring 28 are misaligned. The limiting rod 36 returns to its original position under the elastic force of the return spring 35, preventing the limiting ring 32 from rotating back to its original position. The guide ring 28 restricts the second tube 11 from sliding away from the first tube 1 on one side of the limiting ring 32 by the fixing rod 3, avoiding displacement during the hardening and fusion of the ends of the first tube 1 and the second tube 11, and ensuring the stability of the connection.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
