Description

Technical Field

[0001] This utility model relates to the field of pipe fitting connection technology, and in particular to a pipe fitting connection structure and support. Background Technology

[0002] In settings such as conference rooms, lecture halls, and concerts, microphone stands are typically used to support microphones for speakers. Stands are usually composed of multiple connected tubular sections. When needed, these sections are joined to achieve a predetermined length, allowing the stand to support the microphone at a specific height. When not in use, the stand can be disassembled into its sections for easy storage and transport.

[0003] In related technologies, multiple pipe sections are usually connected by threads. During the connection process, the pipe needs to be rotated many times and tightened with a large force, resulting in low assembly efficiency of the bracket. Utility Model Content

[0004] The main technical problem solved by this utility model embodiment is to provide a pipe connection structure and bracket that can improve the efficiency of installation or disassembly between the first pipe and the second pipe.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this utility model embodiment is: providing a pipe fitting connection structure, including a first pipe fitting and a second pipe fitting. The first pipe fitting includes a first pipe body, a first snap-fit ​​assembly, and a second snap-fit ​​assembly. Both the first and second snap-fit ​​assemblies are connected to the first pipe body and are opposite to each other along the radial direction of the first pipe body. The first snap-fit ​​assembly is provided with a first snap-fit ​​protrusion and a first engagement portion, and the second snap-fit ​​assembly is provided with a second snap-fit ​​protrusion. The first pipe fitting is detachably inserted into the second pipe fitting along the axial direction of the second pipe fitting. The second pipe fitting is provided with a second engagement portion, and both are connected to the outside. The first locking hole and the second locking hole, and the second engaging part are disposed on the inner wall of the second pipe fitting; when the second pipe fitting moves to the first position relative to the first pipe body, the first locking protrusion engages with the first locking hole, and the second locking protrusion engages with the second locking hole to restrict the second pipe fitting from rotating around the axis of the first pipe body relative to the first pipe body, and the first engaging part engages with the second engaging part to restrict the second pipe fitting from moving along the axis of the first pipe body relative to the first pipe body; when the second pipe fitting moves to the second position relative to the first pipe body, the first locking protrusion and the first locking hole are disengaged, the second locking protrusion and the second locking hole are disengaged, and the first engaging part and the second engaging part are disengaged. In this embodiment, the first locking protrusion engages with the first locking hole, and the second locking protrusion engages with the second locking hole to restrict the rotation of the second pipe around the axis of the first pipe body. At the same time, the first and second engaging parts engage to restrict the movement of the second pipe along the axis of the first pipe body, thereby fixing the first and second pipes together. During the assembly process, compared with the threaded connection method in the prior art, the pipe needs to rotate at a smaller angle and the torque required during rotation is smaller, which helps to improve assembly efficiency and reduce assembly difficulty.

[0006] In some embodiments, the first snap-fit ​​assembly includes a first fixing member and a first connecting piece. The first fixing member is connected to the inner wall of the first tube body, the first connecting piece is fixed to the portion of the first fixing member protruding from the first tube body, and a first snap-fit ​​protrusion is disposed at the end of the first connecting piece away from the first fixing member. In this embodiment, by disposing the first snap-fit ​​protrusion at the end of the first connecting piece away from the first fixing member, the first snap-fit ​​protrusion can elastically swing relative to the first fixing member along the radial direction of the first tube body when subjected to external force, facilitating the insertion of the first snap-fit ​​assembly into the second tube. Furthermore, when the second tube is in the first position, the first snap-fit ​​protrusion can remain snapped into the first locking hole, thereby improving the stability of the fixation between the first and second tubes.

[0007] In some embodiments, the first fastener includes a first side plate and a first bottom plate. The first side plate is connected to the inner wall of the first tube body, the first bottom plate is connected to the first side plate, the first connecting piece is fixed to the first bottom plate, and the first engaging portion is disposed on the first side plate.

[0008] In some embodiments, the first fixing member further includes a second side plate, which is connected to the end of the first base plate away from the first side plate. The second side plate is provided with a third engaging portion, and the inner wall of the second pipe is provided with a fourth engaging portion. When the second pipe is in the first position, the third engaging portion and the fourth engaging portion engage to restrict the movement of the second pipe relative to the first pipe body along the axial direction of the first pipe body. When the second pipe is in the second position, the third engaging portion and the fourth engaging portion disengage. In this embodiment, by providing the third engaging portion and the fourth engaging portion, the third engaging portion and the fourth engaging portion can be used together to restrict the movement of the second pipe along the first direction, thereby improving the stability of the fixation between the first pipe and the second pipe.

[0009] In some embodiments, one of the first engaging portion and the second engaging portion is a first slot, and the other is a first limiting protrusion. When the second pipe is in the first position, the first limiting protrusion engages with the first slot; when the second pipe is in the second position, the first limiting protrusion is disengaged from the first slot; and / or

[0010] One of the third and fourth engagement parts is the second slot, and the other is the second limiting protrusion. When the second pipe is in the first position, the second limiting protrusion engages with the second slot. When the second pipe is in the second position, the second limiting protrusion and the second slot are no longer engaged.

[0011] In some embodiments, the first protrusion is provided with a first spherical surface, which is located at the end of the first protrusion away from the first connecting piece.

[0012] In some embodiments, the first snap-fit ​​assembly includes a first fastener, and the first connecting piece is fixed to the first fixing member by the first fastener. By setting the first spherical surface, the contact area between the first snap-fit ​​protrusion and the inner wall of the second pipe can be reduced during the assembly of the first pipe and the second pipe, thereby reducing friction and facilitating the rotation of the second pipe. In addition, during disassembly, it is not necessary to press the first snap-fit ​​protrusion to a position completely separated from the first snap-fit ​​hole. When rotating the second pipe or the first pipe, under the guiding action of the first spherical surface, the first snap-fit ​​protrusion can gradually move closer to the axis, thereby canceling the snap-fit ​​relationship with the first snap-fit ​​hole and reducing the difficulty of disassembling the second pipe.

[0013] In some embodiments, the second snap-fit ​​assembly includes a second fixing member and a second connecting piece. The second fixing member is connected to the inner wall of the first tube body, and the second connecting piece is fixed to the portion of the second fixing member that protrudes from the first tube body. A second snap-fit ​​protrusion is disposed at the end of the second connecting piece away from the second fixing member. In this embodiment, by disposing the second snap-fit ​​protrusion at the end of the second connecting piece away from the second fixing member, the second snap-fit ​​protrusion can elastically swing relative to the second fixing member along the radial direction of the first tube body when subjected to external force, facilitating the insertion of the second snap-fit ​​assembly into the second tube. Furthermore, when the second tube is in the first position, the second snap-fit ​​protrusion can remain engaged in the second snap-fit ​​hole.

[0014] In some embodiments, the second fixing member includes a third side plate and a second bottom plate. The third side plate is connected to the inner wall of the first pipe body, and the second bottom plate is connected to the third side plate. A second connecting piece is fixed to the second bottom plate. The third side plate is provided with a fifth engaging portion, and the inner wall of the second pipe is provided with a sixth engaging portion. When the second pipe is in a first position, the fifth engaging portion and the sixth engaging portion engage to restrict the movement of the second pipe along the axial direction of the first pipe body. When the second pipe is in a second position, the fifth engaging portion and the sixth engaging portion disengage. In this embodiment, by providing the fifth engaging portion and the sixth engaging portion, the fifth engaging portion and the sixth engaging portion can be used together to restrict the movement of the second pipe along the first direction, thereby improving the stability of the fixation between the first pipe and the second pipe.

[0015] To solve the above-mentioned technical problems, another technical solution adopted in this utility model embodiment is to provide a bracket, including the above-mentioned pipe connection structure.

[0016] The beneficial effects of this utility model embodiment are as follows: Unlike the prior art, in this utility model embodiment, both the first and second snap-fit ​​components are connected to the inner wall of the first tube body. The first and second snap-fit ​​components are arranged radially opposite to each other along the first tube body. The first snap-fit ​​component has a first snap-fit ​​protrusion and a first engaging portion, and the second snap-fit ​​component has a second snap-fit ​​protrusion. The second tube fitting has a first snap-fit ​​hole, a second snap-fit ​​hole, and a second engaging portion. Both the first and second snap-fit ​​holes are connected to the outside. The second engaging portion is located on the inner wall of the second tube fitting. When connecting the first and second tube fittings, a portion of the first and second snap-fit ​​components can be inserted... Inside the second pipe fitting, the second pipe fitting is rotated, causing it to move to a first position relative to the first pipe fitting. At this point, the first locking protrusion engages with the first locking hole, and the second locking protrusion engages with the second locking hole, thereby restricting the second pipe fitting from rotating around the axis of the first pipe body relative to it. Furthermore, the first and second engaging parts engage, further restricting the second pipe fitting from moving along the axis of the first pipe body relative to it, thus achieving fixation between the first and second pipe fittings. Compared to threaded fixing, this application requires a smaller rotation angle and eliminates the need for forceful tightening when connecting the first and second pipe fittings, improving assembly efficiency. Additionally, when disassembling the second pipe fitting, the first and second locking protrusions can be pressed through the first and second locking holes to separate the first locking protrusion from the first locking hole and the second locking protrusion from the second locking hole. At this point, the second pipe fitting can rotate around the axis of the first pipe body relative to it. Then, rotating the second pipe fitting disengages the first and second engaging parts, allowing the second pipe fitting to be removed from the first pipe fitting, making disassembly convenient.

[0025] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "inner," "outer," "vertical," "horizontal," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Microphone stands are typically composed of multiple detachable tubular sections. When needed, these sections are joined to achieve a predetermined length, supporting the microphone at a set height for easy speaker use. When not in use, the stand can be disassembled for storage and transport. Because these sections require frequent connection and disconnection, improving the efficiency of installation and disassembly has become a hot research topic.

[0029] In related technologies, two tubes are typically fixed together using a threaded connection. However, this method has drawbacks. If the number of thread turns is too small during assembly, the connection strength between the two tubes will be insufficient. To ensure that the connection strength between each tube section is sufficient to support the microphone, each tube section usually needs to have 5 or more thread turns. This means that each tube section needs to be rotated at least 5 times during assembly, resulting in very low assembly efficiency. Furthermore, a considerable amount of force is required to tighten the tubes during assembly, which is time-consuming and labor-intensive.

[0030] To address the aforementioned problems, this application provides a pipe fitting connection structure and bracket. By engaging a first locking protrusion with a first locking hole and a second locking protrusion with a second locking hole, the rotation of the second pipe fitting relative to the first pipe fitting is restricted. Furthermore, by engaging a first interlocking portion and a second interlocking portion, the movement of the second pipe fitting relative to the first pipe fitting along the axial direction of the first pipe body is restricted, thereby achieving fixation between the first and second pipe fittings. During assembly, by inserting the first and second locking components into the second pipe fitting and then rotating the second pipe fitting to a first position, fixation between the second and first pipe fittings is achieved, thereby improving assembly efficiency.

[0031] The specific structure and function of this application are described in detail below.

[0032] Please see Figure 1 and Figure 2 The pipe connection structure 100 includes a first pipe fitting 1 and a second pipe fitting 2, which are detachably connected. For details, please refer to... Figure 3 The first pipe fitting 1 includes a first pipe body 11, a first snap-fit ​​assembly 12, and a second snap-fit ​​assembly 13. The first snap-fit ​​assembly 12 and the second snap-fit ​​assembly 13 are arranged opposite each other along the radial direction of the first pipe body 11. One end of the first snap-fit ​​assembly 12 and one end of the second snap-fit ​​assembly 13 are both connected to the first pipe body 11, and both the first snap-fit ​​assembly 12 and the second snap-fit ​​assembly 13 at least partially protrude from the first pipe body 11 along the axial direction of the first pipe body 11. The portion of the first snap-fit ​​assembly 12 protruding from the first pipe body 11 is provided with a first snap-fit ​​protrusion 123 and a first engagement portion 12111, and the portion of the second snap-fit ​​assembly 13 protruding from the first pipe body 11 is provided with a second snap-fit ​​protrusion 133. (See also...) Figure 4A portion of the first pipe fitting 1 is detachably inserted into the second pipe fitting 2 along the axial direction. The second pipe fitting 2 is provided with a first locking hole 21, a second locking hole 22, and a second engaging portion 23. One end of the first locking hole 21 communicates with the inner wall of the second pipe fitting 2, and the other end communicates with the outside. The second locking hole 22 is arranged opposite to the first locking hole 21 along the radial direction of the second pipe fitting 2. One end of the second locking hole 22 communicates with the inner wall of the second pipe fitting 2, and the other end communicates with the outside. The second engaging portion 23 is provided on the inner wall of the second pipe fitting 2.

[0033] For ease of description, the axis of the first tube 11 is defined as axis F, and the direction of the axis of the first tube 11 is defined as the first direction X.

[0034] Please combine Figure 3 and Figure 5 ,in, Figure 5 The diagram shows the structure of the pipe fitting connection structure 100 when the second pipe fitting 2 is in the first position. When the second pipe fitting 2 is in the first position relative to the first pipe body 11, the first snap-fit ​​component 12 and the second snap-fit ​​component 13 are at least partially inserted into the second pipe fitting 2. The first snap-fit ​​protrusion 123 snaps into the first snap-fit ​​hole 21, and the second snap-fit ​​protrusion 133 snaps into the second snap-fit ​​hole 22, thereby restricting the second pipe fitting 2 from rotating about the axis F relative to the first pipe body 11. At this time, the first engagement part 12111 and the second engagement part 23 engage to restrict the second pipe fitting 2 from moving along the first direction X relative to the first pipe body 11, thereby achieving the fixation between the first pipe fitting 1 and the second pipe fitting 2. Please refer to... Figure 3 and Figure 6 ,in, Figure 6 The diagram shows the structure of the pipe connection structure 100 when the second pipe groove is in the second position. When the second pipe 2 is in the second position relative to the first pipe body 11, the first locking protrusion 123 is de-engaged with the first locking hole 21, the second locking protrusion 133 is de-engaged with the second locking hole 22, and the first engaging part 12111 is de-engaged with the second engaging part 23. At this time, the second pipe 2 can move relative to the first pipe body 11 along the first direction X to separate the second pipe 2 from the first pipe 1, or the second pipe 2 can rotate relative to the first pipe body 11 around the axis F to move the second pipe 2 relative to the first pipe 1 to the first position, thereby fixing the second pipe 2 and the first pipe 1 together.

[0035] It is worth noting that the assembly process of the first pipe fitting 1 and the second pipe fitting 2 is as follows: First, insert the first snap-fit ​​component 12 and the second snap-fit ​​component 13 of the first pipe fitting 1 into the second pipe fitting 2. At this time, the second pipe fitting 2 is positioned relative to the first pipe fitting 1. Figure 6In the second position, the first locking protrusion 123 and the second locking protrusion 133 both abut against the inner wall of the second pipe fitting 2, and along the first direction X, the projections of the first engaging portion 12111 and the second engaging portion 23 are offset from each other; then, the second pipe fitting 2 or the first pipe fitting 1 is rotated about the axis F, so that the second pipe fitting 2 is in a position relative to the first pipe body 11. Figure 5 In the first position shown, the first locking protrusion 123 engages with the first locking hole 21, and the second locking protrusion 133 engages with the second locking hole 22, thereby restricting the rotation of the second tube 2 relative to the first tube 11 about the axis F. The first engaging part 12111 engages with the second engaging part 23. Along the first direction X, the projection of the first engaging part 12111 and the projection of the second engaging part 23 at least partially overlap, thereby restricting the movement of the second tube 2 relative to the first tube 11 along the first direction X, thereby achieving the fixation between the first tube 1 and the second tube 2. In this embodiment, during the assembly of the first pipe fitting 1 and the second pipe fitting 2, it is only necessary to insert the first snap-fit ​​component 12 and the second snap-fit ​​component 13 of the first pipe fitting 1 into the second pipe fitting 2, and then rotate the first pipe fitting 1 or the second pipe fitting 2 so that the second pipe fitting 2 is rotated relative to the first pipe body 11 to the first position to achieve the fixation between the first pipe fitting 1 and the second pipe fitting 2. Compared with the threaded connection method in the prior art, the pipe fitting needs to rotate at a smaller angle and the torque required during rotation is smaller, which is beneficial to improve assembly efficiency and reduce assembly difficulty.

[0036] It should also be noted that the disassembly process of the first pipe fitting 1 and the second pipe fitting 2 is as follows: Press the first locking protrusion 123 through the first locking hole 21 to make the first locking protrusion 123 move away from the first locking hole 21 in the radial direction of the second pipe fitting 2, and press the second locking protrusion 133 through the second locking hole 22 to make the second locking protrusion 133 move away from the second locking hole 22 in the radial direction of the second pipe fitting 2; then rotate the second pipe fitting 2 or the first pipe fitting 1 so that the second pipe fitting 2 rotates relative to the first pipe body 11 to... Figure 6 The second position is shown in the diagram; finally, the first snap-fit ​​assembly 12 and the second snap-fit ​​assembly 13 are pulled out from the second pipe fitting 2 along the first direction X, completing the disassembly of the first pipe fitting 1 and the second pipe fitting 2. In this embodiment, compared with the threaded connection method in the prior art, the pipe fitting needs to rotate at a smaller angle during the disassembly process, which is beneficial to improving the disassembly efficiency of the pipe fitting.

[0037] In some embodiments, please refer to Figure 5 and Figure 6The first engaging part 12111 is the first slot, and the second engaging part 23 is the first limiting protrusion. When the second pipe 2 is in the first position, the first limiting protrusion engages with the first slot, thereby restricting the movement of the second pipe 2 along the first direction X. When the second pipe 2 is in the second position, the first limiting protrusion and the first slot are unengaged. At this time, the second pipe 2 can move relative to the first pipe body 11 along the first direction X to detach the second pipe 2 from the first pipe 1.

[0038] It is understood that, as not shown in the figure, the first biting part 12111 can be a first limiting protrusion, and the second biting part 23 can be a first slot.

[0039] In some embodiments, please refer to Figure 3 The first snap-fit ​​assembly 12 includes a first fixing member 121 and a first connecting piece 122. The first fixing member 121 is connected to the inner wall of the first tube 11. At least a portion of the first fixing member 121 protrudes from the first tube 11 along the first direction X. One end of the first connecting piece 122 is fixed to the portion of the first fixing member 121 that protrudes from the first tube 11, and the other end of the first connecting piece 122 extends away from the first tube 11 along the first direction X. The aforementioned first snap-fit ​​protrusion 123 is disposed at the end of the first connecting piece 122 away from the first fixing member 121, and the first snap-fit ​​protrusion 123 is located on the side of the first connecting piece 122 opposite to the second snap-fit ​​assembly 13. In this embodiment, by setting the first locking protrusion 123 at the end of the first connecting piece 122 away from the first fixing member 121, the first locking protrusion 123 can elastically swing relative to the first fixing member 121 in the radial direction of the first tube body 11 when subjected to external force, which facilitates the insertion of the first locking assembly 12 into the second tube 2. When the second tube 2 is in the first position, the first locking protrusion 123 can remain locked in the first locking hole 21, thereby improving the stability of the fixation between the first tube 1 and the second tube 2.

[0040] In some embodiments, please refer to Figure 3 The first fixing member 121 includes a first side plate 1211 and a first bottom plate 1212. The first side plate 1211 is connected to the inner wall of the first tube 11, and the first bottom plate 1212 is connected to the first side plate 1211. The first connecting piece 122 is fixed to the first bottom plate 1212, and the first engaging part 12111 is disposed on the first side plate 1211.

[0041] In some embodiments, please refer to Figure 3 The first fixing member 121 includes a second side plate 1213, which is connected to the end of the first base plate 1212 away from the first side plate 1211. The second side plate 1213 is also connected to the inner wall of the first tube body 11. The second side plate 1213 is provided with a third engaging portion 12131, and the inner wall of the second tube 2 is provided with a fourth engaging portion 24. Please refer to [link / reference]. Figure 5 When the second pipe fitting 2 is in the first position, the third engaging portion 12131 engages with the fourth engaging portion 24. Along the first direction X, the projection of the third engaging portion 12131 at least partially overlaps with the projection of the fourth engaging portion 24, thereby restricting the movement of the second pipe fitting 2 along the first direction X. (See also...) Figure 6 When the second pipe fitting 2 is in the second position, the third engaging portion 12131 and the fourth engaging portion 24 are no longer engaged. Along the first direction X, the projections of the third engaging portion 12131 and the fourth engaging portion 24 are misaligned, thereby removing the restriction on the second pipe fitting 2 in the first direction X. In this embodiment, by providing the third engaging portion 12131 and the fourth engaging portion 24, they can jointly restrict the movement of the second pipe fitting 2 along the first direction X, thereby improving the stability of the fixation between the first pipe fitting 1 and the second pipe fitting 2.

[0042] In some embodiments, the first fastener 121 and the first tube 11 are integrally formed to improve the stability of the fixation between the first fastener 121 and the first tube 11.

[0043] In some embodiments, please refer to Figure 5 The third engaging portion 12131 is the second slot, and the fourth engaging portion 24 is the second limiting protrusion. When the second pipe fitting 2 is in the first position, the second limiting protrusion engages with the second slot, thereby restricting the movement of the second pipe fitting 2 along the first direction X. Please refer to [link / reference]. Figure 6 When the second pipe fitting 2 is in the second position, the second limiting protrusion and the second slot are no longer engaged. At this time, the second pipe fitting 2 can move relative to the first pipe body 11 along the first direction X to detach the second pipe fitting 2 from the first pipe fitting 1.

[0044] It is understood that, as not shown in the figure, the third occlusal part 12131 can be the second limiting protrusion, and the fourth occlusal part 24 is the second slot.

[0045] In some embodiments, please refer to Figure 3 The first snap-fit ​​assembly 12 includes a first fastener 124, and the first connecting piece 122 is fixed to the first fixing member 121 by the first fastener 124.

[0046] In some embodiments, the first fastener 124 is a screw, and the first connecting piece 122 is fixed to the first fixing member 121 by the screw, which provides a stable and reliable connection and is easy to install.

[0047] In some embodiments, please refer to Figure 6The first locking protrusion 123 is provided with a first spherical surface 1231, which is located at the end of the first locking protrusion 123 away from the first connecting piece 122. By providing the first spherical surface 1231, the contact area between the first locking protrusion 123 and the inner wall of the second pipe 2 can be reduced during the assembly of the first pipe 1 and the second pipe 2, thereby reducing friction and facilitating the rotation of the second pipe 2. In addition, during disassembly, it is not necessary to press the first locking protrusion 123 to a position completely separated from the first locking hole 21. When rotating the second pipe 2 or the first pipe 1, under the guidance of the first spherical surface 1231, the first locking protrusion 123 can gradually move closer to the axis F, thereby canceling the locking relationship with the first locking hole 21 and reducing the difficulty of disassembling the second pipe 2.

[0048] In some embodiments, please refer to Figure 3 The second snap-fit ​​assembly 13 includes a second fixing member 131 and a second connecting piece 132. The second fixing member 131 is connected to the inner wall of the first tube body 11. At least a portion of the second fixing member 131 protrudes from the first tube body 11 along the first direction X, and the second fixing member 131 and the aforementioned first fixing member 121 are arranged opposite each other along the radial direction of the first tube body 11. One end of the second connecting piece 132 is fixed to the portion of the second fixing member 131 that protrudes from the first tube body 11. A second snap-fit ​​protrusion 133 is disposed at the end of the second connecting piece 132 away from the second fixing member 131, and the second snap-fit ​​protrusion 133 is located at the end of the second connecting piece 132 opposite to the first connecting piece 122. In this embodiment, by setting the second latching protrusion 133 at the end of the second connecting piece 132 away from the second fixing member 131, the second latching protrusion 133 can elastically swing relative to the second fixing member 131 in the radial direction of the first tube 11 when subjected to external force, which facilitates the insertion of the second latching assembly 13 into the second tube 2, and when the second tube 2 is in the first position, the second latching protrusion 133 can remain latched in the second latching hole 22.

[0049] In some embodiments, please refer to Figure 3 The second fastener 131 includes a third side plate 1311 and a second bottom plate 1312. The third side plate 1311 is connected to the inner wall of the first tube 11, and the second bottom plate 1312 is connected to the third side plate 1311. The second connecting piece 132 is fixed to the second bottom plate 1312.

[0050] In some embodiments, please refer to Figure 7The third side plate 1311 is provided with a fifth engaging portion 13111, and the inner wall of the second pipe fitting 2 is provided with a sixth engaging portion 25. When the second pipe fitting 2 is in the first position, the fifth engaging portion 13111 and the sixth engaging portion 25 engage. At this time, along the first direction X, the projection of the fifth engaging portion 13111 and the projection of the sixth engaging portion 25 at least partially overlap, so that the fifth engaging portion 13111 and the sixth engaging portion 25 can jointly restrict the movement of the second pipe fitting 2 along the first direction X. Please refer to [link to relevant documentation]. Figure 6 When the second pipe fitting 2 is in the second position, the fifth engaging portion 13111 and the sixth engaging portion 25 are no longer engaged. At this time, along the first direction X, the projections of the fifth engaging portion 13111 and the sixth engaging portion 25 are offset from each other, thereby removing the restriction on the second pipe fitting 2 in the first direction X. In this embodiment, by providing the fifth engaging portion 13111 and the sixth engaging portion 25, the fifth engaging portion 13111 and the sixth engaging portion 25 can be used together to restrict the movement of the second pipe fitting 2 along the first direction X, thereby improving the stability of the fixation between the first pipe fitting 1 and the second pipe fitting 2.

[0051] In some embodiments, the second fastener 131 and the first tube 11 are integrally formed to improve the stability of the fixation between the second fastener 131 and the first tube 11.

[0052] In some embodiments, one of the fifth engagement portion 13111 and the sixth engagement portion 25 is a third slot, and the other is a third limiting protrusion. When the second pipe 2 is in the first position, the third limiting protrusion engages with the third slot to restrict the movement of the second pipe 2 along the first direction X. When the second pipe 2 is in the second position, the engagement between the third limiting protrusion and the third slot is canceled.

[0053] In some embodiments, please refer to Figure 3 and Figure 7 The second fixing member 131 includes a fourth side plate 1313, which is connected to the end of the second bottom plate 1312 away from the third side plate 1311. The fourth side plate 1313 is also connected to the inner wall of the first tube 11. The fourth side plate 1313 is provided with a seventh engaging portion 13131, and the inner wall of the second tube 2 is provided with an eighth engaging portion 26. When the second tube 2 is in the first position, the seventh engaging portion 13131 and the eighth engaging portion 26 engage. At this time, along the first direction X, the projection of the seventh engaging portion 13131 and the projection of the eighth engaging portion 26 at least partially overlap, so that the seventh engaging portion 13131 and the eighth engaging portion 26 can jointly restrict the movement of the second tube 2 along the first direction X. Please refer to [link to relevant documentation]. Figure 6When the second pipe fitting 2 is in the second position, the seventh engaging portion 13131 and the eighth engaging portion 26 are no longer engaged. At this time, along the first direction X, the projections of the seventh engaging portion 13131 and the eighth engaging portion 26 are offset from each other, thereby removing the restriction on the second pipe fitting 2 in the first direction X. In this embodiment, by providing the seventh engaging portion 13131 and the eighth engaging portion 26, the seventh engaging portion 13131 and the eighth engaging portion 26 can be used together to restrict the movement of the second pipe fitting 2 along the first direction X, thereby improving the stability of the fixation between the first pipe fitting 1 and the second pipe fitting 2.

[0054] In some embodiments, one of the seventh engagement portion 13131 and the eighth engagement portion 26 is a fourth slot, and the other is a fourth limiting protrusion. When the second tube 2 is in the first position, the fourth limiting protrusion engages with the fourth slot to restrict the movement of the second tube 2 along the first direction X. When the second tube 2 is in the second position, the engagement between the fourth limiting portion and the fourth slot is canceled.

[0055] In some embodiments, please refer to Figure 3 The second snap-fit ​​assembly 13 also includes a second fastener 134, through which the second connecting piece 132 is fixed to the second base plate 1312. The second fastener 134 can be a screw. Fixing with screws can ensure high connection stability between the second connecting piece 132 and the second base plate 1312 and facilitate assembly.

[0056] In some embodiments, please refer to Figure 6 The second locking protrusion 133 is provided with a second spherical surface 1331, which is located at the end of the second locking protrusion 133 away from the second connecting piece 132. By providing the second spherical surface 1331, the contact area between the second locking protrusion 133 and the inner wall of the second pipe 2 can be reduced during the assembly of the first pipe 1 and the second pipe 2, thereby reducing friction and facilitating the rotation of the second pipe 2. In addition, during disassembly, it is not necessary to press the second locking protrusion 133 to a position completely separated from the second locking hole 22. When rotating the second pipe 2 or the first pipe 1, under the guidance of the second spherical surface 1331, the second locking protrusion 133 can gradually move closer to the axis F, thereby canceling the locking relationship with the second locking hole 22 and reducing the difficulty of disassembling the second pipe 2.

[0057] In this embodiment of the present invention, both the first snap-fit ​​component 12 and the second snap-fit ​​component 13 are connected to the inner wall of the first tube body 11. The first snap-fit ​​component 12 and the second snap-fit ​​component 13 are arranged radially opposite to each other along the first tube body 11. The first snap-fit ​​component 12 is provided with a first snap-fit ​​protrusion 123 and a first engagement portion 12111, and the second snap-fit ​​component 13 is provided with a second snap-fit ​​protrusion 133. The second tube 2 is provided with a first snap-fit ​​hole 21, a second snap-fit ​​hole 22, and a second engagement portion 23. Both the first snap-fit ​​hole 21 and the second snap-fit ​​hole 22 are in communication with the outside. The second engagement portion 23 is disposed on the inner wall of the second tube 2. When connecting the first tube 1 and the second tube 2, a portion of the first snap-fit ​​component 12 and the second snap-fit ​​component 13 can be inserted into the second tube 2. Then, the second pipe fitting 2 is rotated so that the second pipe fitting 2 moves to the first position relative to the first pipe fitting 1. At this time, the first locking protrusion 123 engages with the first locking hole 21, and the second locking protrusion 133 engages with the second locking hole 22, thereby restricting the second pipe fitting 2 from rotating around the axis of the first pipe body 11 relative to the first pipe body 11. The first engaging part 12111 and the second engaging part 23 engage, thereby restricting the second pipe fitting 2 from moving along the axis of the first pipe body 11 relative to the first pipe body 11, thus achieving the fixation between the first pipe fitting 1 and the second pipe fitting 2. Compared with the threaded fixing method, this application requires a smaller rotation angle when connecting the first pipe fitting 1 and the second pipe fitting 2, and does not require force to tighten, which can improve assembly efficiency. In addition, when disassembling the second pipe fitting 2, the first locking protrusion 123 and the second locking protrusion 133 can be pressed through the first locking hole 21 and the second locking hole 22 to separate the first locking protrusion 123 from the first locking hole 21 and the second locking protrusion 133 from the second locking hole 22. At this time, the second pipe fitting 2 can rotate around the axis F of the first pipe body 11 relative to the first pipe body 11. Then, the second pipe fitting 2 is rotated to disengage the first engaging part 12111 and the second engaging part 23, so that the second pipe fitting 2 can be removed from the first pipe fitting 1, which is convenient for disassembly.
