[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] The present application is further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 5As shown, the present application provides a tube body adapter assembly, including two connecting members 1 and a rotating shaft body 2, the first end 11 of the connecting member 1 is suitable for connecting to the tube body 4, and the second end 12 of the connecting member 1 is provided with a blocking portion 121 and a limiting portion 122, the blocking portions 121 of the two connecting members 1 are suitable for being rotatably connected to the two sides of the rotating shaft body 2, and forming a limiting cavity 21 along the circumference of the rotating shaft body 2, the limiting cavity 21 is suitable for accommodating the limiting portion 122, so that the limiting portion 122 can move along the circumference of the rotating shaft body 2, the design of the blocking portion 121 and the limiting portion 122 can facilitate the matching and docking between the two connecting members 1 and the rotating shaft body 2, thereby reducing the overall connection and installation difficulty, the limiting cavity 21 formed by the blocking portions 121 of the two connecting members 1 can also improve the connection strength and stability between the two connecting members 1 by blocking and fixing the limiting portion 122, and reduce the probability of deformation and damage at the connection of the two connecting members 1.

[0028] The limiting portion 122 can also improve the connection strength between the blocking portion 121 and the main body of the connecting member 1, and further reduce the probability of deformation between the two connecting members 1.

[0029] In some embodiments, limiting surfaces 1221 are provided on both sides of the limiting portion 122 along the circumference of the rotating shaft body 2. The limiting surface 1221 of the limiting portion 122 of the connecting member 1 is suitable for cooperating and abutting with the limiting surface 1221 of the limiting portion 122 of another connecting member 1. When the two connecting members 1 rotate relative to each other, the limiting portions 122 thereon will cause structural interference on both sides of the limiting portion 122 when they rotate close to each other. Therefore, the limiting surface 1221 formed by cutting off a part of the limiting portion 122 can eliminate the interference between the two limiting portions 122, and can increase the contact area of ​​the two limiting portions 122, thereby reducing the probability of collision damage. At the same time, by designing the angle of the limiting surface 1221, the minimum angle between the two connecting members 1 can also be determined to limit excessive rotation of the connecting members 1 and improve stability.

[0030] like Figures 1 to 3 In the illustrated embodiment, when the limiting surface 1221 on the limiting portion 122 of the connecting member 1 cooperates and abuts with the limiting surface 1221 on the limiting portion 122 of another connecting member 1, the angle between the two connecting members 1 is 90 degrees, so that the limiting portion 122 has a positioning effect, that is, when the two connecting members 1 abut against each other, the angle between the two tube bodies 4 connected thereto is 90 degrees. The purpose of such a setting is that when the two tube bodies 4 need to be vertically connected, there is no need to judge and correct the two tube bodies 4, thereby improving the efficiency of installation and connection. At the same time, it is also possible to strengthen the strength of the connection structure in the connection state where the two tube bodies 4 are vertically connected, thereby increasing the bearing capacity.

[0031] In some embodiments, when two connectors 1 are connected, the projections of the two blocking portions 121 and the rotating shaft 2 on the cross section of the connector 1 are completely located within the cross section of the connector 1, ensuring that the structure at the connection between the two connectors 1 is sufficiently compact, the transition is smoother, the volume of the connection is reduced, and it is not easy to cause structural interference with the outside.

[0032] In some embodiments, the first end 11 of the connector 1 is cylindrical, and the first end 11 can be nested and connected with the tube body 4. The two connectors 1 can help the two tube bodies 4 to achieve a straight-through connection, and the angle adjustment between the two tube bodies 4 can be achieved by rotating the two connectors 1. The two connectors 1 have common parts under this connection method, so the production and processing costs can also be reduced.

[0033] In some embodiments, a polygonal channel is opened axially at the first end 11 of the connector 1, and a plurality of connecting holes 112 are opened radially at the first end 11 of the connector 1. The connecting holes 112 pass through the connector 1 perpendicular to the side wall of the polygonal channel. The connecting holes 112 are used to cooperate with the tube body 4 for positioning through the universal fastener 3. The setting of the polygonal channel can increase the wall thickness of the connector 1 except the connecting holes 112, thereby improving the connection strength between the connector 1 and the tube body 4 and reducing the probability of deformation of the connector 1 and the tube body 4.

[0034] like Figure 3 In the illustrated embodiment, the polygonal channel is a rectangular channel 111 , which is easy to process and has a stable structure. At least one connecting hole 112 is provided through each side of the rectangular channel 111 .

[0035] like Figure 4 In the illustrated embodiment, the first end 11 of the connector 1 is provided with a connecting sleeve 113, and the connection direction of the first end 11 of the connector 1 and the second end 12 of the connector 1 is perpendicular to the axial direction of the connecting sleeve 113. In this state, structural interference is not likely to occur between the first sleeve and the second end 12. The connector 1 provided with the connecting sleeve 113 can realize multi-way connection of multiple pipe bodies 4 by connecting with other different types of connectors 1.

[0036] like Figure 5 In the illustrated embodiment, one form of the multi-way setting is: two connectors 1 are taken as a group, and the connecting sleeve 113 is suitable for arranging multiple groups of connectors 1 along the circumferential direction to realize four-way, five-way or even more connection forms, and it is only necessary to process the connecting sleeve 113 with the corresponding number of connectors 1, and the tube body 4 circumferentially connected to the connecting sleeve 113 can rotate freely relative to the tube body 4 at the connecting sleeve 113 without structural interference.

[0037] In some embodiments, another form of multi-way setting is: two connectors 1 provided with connecting sleeves 113 are connected to each other to realize a four-way structure of two tube bodies 4. By rotating the two connectors 1, the two tube bodies 4 can be parallel or set to have an angle.

[0038] like Figure 3 In the illustrated embodiment, a clamping block 114 is circumferentially provided on the first end 11 of the connector 1 near the second end 12 of the connector 1. The clamping block 114 can be interference fit with the tube body 4, thereby reducing the probability of the tube body 4 being separated from the first end 11 and improving the connection stability. The outer diameter of the first end 11 of the connector 1 at the clamping block 114 is smaller than the outer diameter of the second end 12 of the connector 1, and the outer diameter of the second end 12 of the connector 1 is larger than the outer diameter of the first end 11, which can play a blocking role and prevent the entire connector 1 from entering the tube body 4, thereby improving the connection stability.

[0039] In some embodiments, when the tube body 4 is sleeved on the first end 11 of the connector 1, the second end 12 of the connector 1 is flush with the outer diameter of the tube body 4, making the surface transition between the two smoother and reducing the probability of collision when people come into contact.

[0040] In some embodiments, the width of the limiting portion 122 is equal to the width of the limiting cavity 21, so that the limiting portion 122 can provide sufficient support to the blocking portions 121 on both sides, thereby reducing the probability of structural deformation.

[0041] In some embodiments, the blocking portion 121 and the rotating shaft body 2 are connected by a fastener 3. The blocking portion 121 is provided with a accommodating cavity 1211 on the side away from the rotating shaft body 2. The accommodating cavity 1211 is suitable for accommodating the fastener 3, and makes the outer end of the fastener 3 lower than the outer surface of the blocking portion 121 on the side away from the rotating shaft body 2. The accommodating cavity 1211 can prevent the fastener 3 from protruding from the outer surface of the blocking portion 121 on the side away from the rotating shaft body 2, thereby reducing the probability of bumps when people come into contact with it, and at the same time protecting the fastener 3 from damage.

[0042] In some embodiments, the fastener 3 is a threaded fastener 3 , and the fastener 3 is at least threadedly connected to the rotating shaft 2 .

[0043] In some embodiments, the rotating shaft 2 is fixedly connected to the blocking portion 121 of one of the connecting members 1, which can further improve the connection strength and stability of the connection structure.

[0044] In some embodiments, the rotating shaft 2 is integrally formed with the blocking portion 121 of one of the connecting members 1 , which can further enhance the connection strength and stability of the connection structure.
