Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

The term "more than two" includes two or more than two situations.

[0030] Please refer to the following Figure 1-6 The pipe body docking structure 10 according to the embodiment of the present application is described.

[0031] like Figure 1As shown, the pipe body docking structure 10 according to the embodiment of the present application includes: a first pipe body 1, a second pipe body 2, a connecting pipe 3 and an operating member 4.

[0032] like Figure 1 As shown, the first tube body 1 has a first butt end 11, the second tube body 2 has a second butt end 21, the second butt end 21 is used to be arranged opposite to the first butt end 11, the connecting tube 3 is movably arranged on the first tube body 1, one end of the connecting tube 3 is located in the first tube body 1, and the other end is suitable for extending out of the first tube body 1 and being used for being inserted into the second tube body 2, the operating member 4 is connected to the connecting tube 3, the operating member 4 is movably penetrated through the tube wall of the first tube body 1, and the operating member 4 is suitable for moving along the extension direction of the first tube body 1.

[0033] Therefore, even when there is no movable space in the axial direction of the first tube body 1 and the second tube body 2, the movement of the connecting tube 3 can be achieved through the operating member 4, thereby achieving the docking of the first tube body 1 and the second tube body 2, which is beneficial to improving the construction efficiency.

[0034] It is understandable that at least one of the first tube body 1 and the second tube body 2 can be a steel tube, a plastic tube or a tube made of other materials, and the material of the connecting tube 3 can be the same as that of the first tube body 1, or the material of the connecting tube 3 can be different from that of the first tube body 1, which is not limited here.

[0035] For example, the first tube body 1 and the second tube body 2 are both steel tubes, and the connecting tube 3 is also a steel tube. The steel tube can be a round steel tube or a rectangular steel tube, wherein the inner diameters of the first tube body 1 and the second tube body 2 are the same, the inner diameter of the connecting tube 3 is smaller than the inner diameter of the first tube body 1, and the outer peripheral wall of the connecting tube 3 is suitable for fitting and connecting with the inner wall of the first tube body 1 and / or the second tube body 2, so that the inner wall of the first tube body 1 and / or the second tube body 2 can play a certain guiding role in the movement of the connecting tube 3.

[0036] The operating member 4 may include a handle or a push rod, etc. The operating member 4 may be movably disposed through the tube wall of the first tube body 1 and connected to the connecting tube 3, and the operating member 4 is suitable for moving along the extension direction of the first tube body 1, so that the operating member 4 can drive the connecting tube 3 to move synchronously along the extension direction of the first tube body 1.

[0037] Among them, it can be understood that, since the operating member 4 can be movably penetrated through the tube wall of the first tube body 1 and is connected to the connecting tube 3, the operating member 4 is actually located on the radial outside of the connecting tube 3. In this way, the setting of the operating member 4 will not occupy the axial space of the first tube body 1 and the second tube body 2. In this way, even if there is no axial space for movement between the first tube body 1 and the second tube body 2, the movement of the connecting tube 3 can be achieved through the operating member 4, thereby achieving the docking of the first tube body 1 and the second tube body 2.

[0038] For example, in some usage scenarios, the second docking end 21 is arranged opposite to the first docking end 11, for example, the second docking end 21 is arranged opposite to the first docking end 11, or the second docking end 21 is arranged opposite to the first docking end 11 at a certain angle. At this time, the operating member 4 can be controlled to drive the connecting tube 3 to move synchronously along the extension direction of the first tube body 1, so that the other end of the connecting tube 3 extends out of the first tube body 1 and is inserted into the second tube body 2, thereby realizing the docking of the first tube body 1 and the second tube body 2. After the first tube body 1 and the second tube body 2 are docked, the connecting tube 3 can be welded to the first tube body 1, and the first tube body 1 and the second tube body 2 can be welded to ensure the docking stability of the first tube body 1 and the second tube body 2.

[0039] Therefore, when there is no movable space in the axial direction of the first tube body 1 and the second tube body 2 , the movement of the connecting tube 3 can be achieved through the operating member 4 , thereby achieving the docking of the first tube body 1 and the second tube body 2 .

[0040] The connection between the operating member 4 and the connecting pipe 3 may be a fixed connection, a detachable connection or a dynamic connection, which is not limited here.

[0041] According to the pipe body docking structure 10 of the embodiment of the present application, the operating member 4 can be movably arranged on the pipe wall of the first pipe body 1 and connected to the connecting pipe 3, so that the arrangement of the operating member 4 does not need to occupy the axial space between the first pipe body 1 and the second pipe body 2. In this way, even if there is no movable space in the axial direction of the first pipe body 1 and the second pipe body 2, the movement of the connecting pipe 3 can be achieved through the operating member 4, and then the docking of the first pipe body 1 and the second pipe body 2 can be achieved, which is beneficial to improve the construction efficiency.

[0042] In some embodiments, Figure 2 and Figure 3 As shown, the wall of the first tube body 1 is provided with a mounting hole 12, and as shown in FIG. Figure 4 As shown, the operating member 4 is movably disposed in the mounting hole 12 , and the mounting hole 12 is arranged close to the first docking end 11 .

[0043] Thus, the interference between the tube wall of the first tube body 1 and the operating member 4 can be avoided, so as to facilitate the design that the operating member 4 can be movably arranged on the tube wall of the first tube body 1 and connected to the connecting tube 3. At the same time, the mounting hole 12 is arranged close to the first docking end 11, so as to reduce the movement stroke of the operating member 4, thereby reducing the difficulty of operation. In particular, after the first tube body 1 and the second tube body 2 are docked, the connecting tube 3 and the first tube body 1 can be welded at the mounting hole 12, thereby reducing the difficulty of welding the connecting tube 3 and the first tube body 1.

[0044] In some embodiments, Figure 1As shown, in the extension direction of the first tube body 1 , the minimum length of the mounting hole 12 is greater than the minimum distance between the first butt end 11 and the mounting hole 12 .

[0045] For example Figure 1 As shown, the minimum length of the mounting hole 12 is L1, the minimum distance between the first butt end 11 and the mounting hole 12 is L2, and L1 is greater than L2.

[0046] Thus, when the operating member 4 moves in the mounting hole 12 along the extension direction of the first tube body 1, the maximum stroke of the operating member 4 is greater than the minimum distance between the first docking end 11 and the mounting hole 12, so that when the operating member 4 moves to the position closest to the first docking end 11, the other end of the connecting tube 3 can definitely extend out of the first docking end 11, thereby facilitating the other end of the connecting tube 3 to extend out of the first tube body 1 and be inserted into the second tube body 2, thereby achieving docking between the first tube body 1 and the second tube body 2.

[0047] In some embodiments, in the extension direction of the first tube body 1 , the length of the connecting tube 3 is greater than the sum of the maximum distance from the mounting hole 12 to the first docking end 11 and the length of the mounting hole 12 .

[0048] For example, in this way, when the operating member 4 moves to the position closest to the first docking end 11, the other end of the connecting tube 3 can definitely extend out of the first docking end 11, thereby facilitating the other end of the connecting tube 3 to extend out of the first tube body 1 and be inserted into the second tube body 2, thereby achieving the docking of the first tube body 1 and the second tube body 2.

[0049] At the same time, it can ensure that when the operating member 4 moves to the position closest to the first docking end 11, the installation hole 12 is still partially blocked by the wall of the connecting pipe 3 to avoid leakage of the first tube body 1 at the installation hole 12.

[0050] In some embodiments, the wall thickness of the portion of the connecting tube 3 opposite to the mounting hole 12 is greater than or equal to the wall thickness of the first tube body 1 .

[0051] Therefore, when the first tube body 1 and the second tube body 2 are connected via the connecting tube 3 and the tube wall of the connecting tube 3 blocks the mounting hole 12, the effective cross-section of the portion of the connecting tube 3 opposite to the mounting hole 12 is not less than the effective cross-section of the first tube body 1, thereby balancing the stress and avoiding the problem of stress concentration at the portion of the connecting tube 3 opposite to the mounting hole 12.

[0052] In some embodiments, one end of the operating member 4 away from the connecting tube 3 protrudes from the outer peripheral wall of the first tube body 1 .

[0053] Therefore, it is convenient for the operator to operate the operating member 4 outside the outer peripheral wall of the first tube body 1 , so as to reduce the difficulty of operating the operating member 4 .

[0054] In some embodiments, the outer diameter of the connecting tube 3 is smaller than the inner diameter of the first tube body 1. For example, the difference between the inner diameter of the first tube body 1 and the outer diameter of the connecting tube 3 is greater than or equal to 1 mm and less than or equal to 5 mm. This makes it easier to assemble the connecting tube 3 and the first tube body 1.

[0055] In some embodiments, the inner diameter of the connecting tube 3 is slightly smaller than the inner diameter of the first tube body 1 and / or the second tube body 2. In this way, after the first tube body 1 and the second tube body 2 are docked, the occupation of the internal space of the first tube body 1 and / or the second tube body 2 by the connecting tube 3 can be reduced.

[0056] In some embodiments, the operating member 4 is connected to the connecting pipe 3 by welding, thereby facilitating the connection strength between the operating member 4 and the connecting pipe 3, thereby enhancing the connection stability between the two.

[0057] In other embodiments, the operating member 4 is connected to the connecting tube 3 by magnetic attraction. This facilitates the connection stability between the operating member 4 and the connecting tube 3 and facilitates the assembly and disassembly of the operating member 4. Of course, in other embodiments, the connection between the operating member 4 and the connecting tube 3 may be by snap-on, plug-in or other connection methods, which are not limited here.

[0058] like Figure 5 As shown, the present application also proposes a pipe body docking method.

[0059] The pipe body docking method according to an embodiment of the present application is used for the pipe body docking structure 10 of any one of the above embodiments.

[0060] Please refer to Figure 5 , pipe body docking methods include:

[0061] S10: Install the connecting tube 3 in the first tube body 1. That is, insert the connecting tube 3 from the first butt end 11 into the first tube body 1 to facilitate the subsequent movement of the connecting tube 3.

[0062] S20: The first butt end 11 and the second butt end 21 are arranged opposite to each other. For example, the second butt end 21 and the first butt end 11 are arranged opposite to each other, or the second butt end 21 and the first butt end 11 are arranged opposite to each other at a certain angle, so that the first tube body 1 and the second tube body 2 can be initially positioned.

[0063] S30: Move the connecting tube 3 so that one end of the connecting tube 3 extends out of the first tube body 1 until the connecting tube 3 is plugged into the second tube body 2. In this way, the first tube body 1 and the second tube body 2 can be docked.

[0064] In some embodiments, please refer to Figure 6 The pipe body docking method also includes:

[0065] S40: When the connecting pipe 3 is inserted into the second pipe body 2, the connecting pipe 3 is welded to the first pipe body 1. In this way, the connecting pipe 3 and the first pipe body 1 can be relatively fixed, thereby preventing the connecting pipe 3 from malfunctioning and affecting subsequent operations.

[0066] S50: Move the first tube body 1 or the second tube body 2 until the distance between the first butt end 11 and the second butt end 21 is a preset distance. For example, the first tube body 1 may be moved toward the direction close to the second tube body 2 so that the distance between the first butt end 11 and the second butt end 21 is a preset distance, so as to facilitate subsequent welding of the first tube body 1 and the second tube body 2.

[0067] Alternatively, the second tube body 2 can be moved in a direction close to the first tube body 1 so that the distance between the first butt end 11 and the second butt end 21 is a preset distance, so as to facilitate the subsequent welding of the first tube body 1 and the second tube body 2; or, the first tube body 1 and the second tube body 2 can be moved at the same time so that the first tube body 1 and the second tube body 2 are relatively close, and the distance between the first butt end 11 and the second butt end 21 is a preset distance, so as to facilitate the subsequent welding of the first tube body 1 and the second tube body 2.

[0068] S60: When the distance between the first butt end 11 and the second butt end 21 is a preset distance, the first butt end 11 and the second butt end 21 are welded.

[0069] For example, the preset distance is 5 mm-15 mm, which indicates that the distance between the first butt end 11 and the second butt end 21 is relatively close, so as to facilitate welding of the first butt end 11 and the second butt end 21 and reduce the difficulty of welding the first butt end 11 and the second butt end 21 .

[0070] In some usage scenarios, when the above-mentioned pipe body docking method is used to dock the pipe body docking structure 10, the specific docking method is as follows:

[0071] 1) A mounting hole 12 is partially opened on the wall of the first tube body 1 near the first butt end 11, the height of the mounting hole 12 is slightly larger than the size of the operating member 4, and the length of the mounting hole 12 is larger than the minimum distance between the mounting hole 12 and the first butt end 11;

[0072] 2) Insert the connecting tube 3 into the first tube body 1 from the first butt end 11;

[0073] 3) The operating member 4 is welded in the area corresponding to the connecting pipe 3 and the mounting hole 12. The operating member 4 should be welded along the mounting hole 12 in the radial direction of the first tube body 1 to facilitate holding and reduce the space occupied in the axial direction of the connecting pipe 3. The operating member 4 is located on the side of the area corresponding to the connecting pipe 3 and the mounting hole 12 away from the first butt end 11;

[0074] 4) Place the second tube body 2 at the designated position and align the second docking end 21 with the first docking end 11. Push the connecting tube 3 into the second tube body 2 through the operating member 4, align the first docking end 11 with the second docking end 21, and leave a gap of 5 mm to 15 mm between the first docking end 11 and the second docking end 21.

[0075] 5) The first butt joint end 11 and the second butt joint end 21 are butt-jointed by welding the first tube body 1 and the second tube body 2.

[0076] 6) After the first tube body 1 and the second tube body 2 are butt-jointed, the operating member 4 is statically cut off, and the first tube body 1 and the connecting tube 3 are welded.

[0077] Of course, in the above-mentioned specific docking method, the operation sequence is only used for illustration and does not necessarily limit the operation sequence. In some other usage scenarios, the operation sequence may be adjusted as needed.

[0078] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0079] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
