Technical Field

[0001] This utility model relates to the field of battery equipment technology, specifically to a mating pipe, a pipe connector assembly, a piping system, and a battery device. Background Technology

[0002] In existing battery equipment piping systems, there are numerous branching pipes. To adjust the flow distribution in each battery pack layer, various pipe fittings with different inner diameters are typically required to regulate the flow in each pipe. For a single battery cluster piping system, different inner diameter pipe fittings are needed in different layers; for multiple battery cluster piping systems, different battery clusters and / or different layers of the same battery cluster also require different inner diameter pipe fittings. This results in high complexity for manufacturers assembling piping systems and makes them prone to misinstallation due to human factors. Utility Model Content

[0003] The purpose of this invention is to provide a mating pipe, a pipe fitting assembly, a piping system, and a battery device that can identify the installation position information of the mating pipe in the piping system, thereby improving the assembly accuracy and installation efficiency of the pipe fitting assembly in the piping system.

[0004] To achieve the objectives of this utility model, the following technical solution is provided: In a first aspect, this utility model provides a mating pipe, including a pipe body and an identification structure. The pipe body is used to mate with a pipe fitting. The identification structure is disposed on the outer periphery of the pipe body. The identification structure includes an adjusting member and an identification member. The adjusting member is used to adjust the state of the identification member so that the identification member identifies the installation position information of the mating pipe in the pipeline system.

[0005] In one embodiment, there are multiple markers, including a first marker and a second marker. The first marker is used to identify the installation position information of the mating tube in a first direction, and the second marker is used to identify the installation position information of the mating tube in a second direction.

[0010] In one embodiment, the display frame includes a mounting surface, and the adjusting member is movably connected to the mounting surface. When the adjusting member extends from the mounting surface, the adjusting member rotates to adjust the rotation of the display unit.

[0027] The battery device in this embodiment of the present invention uses the pipeline system 1000 in this embodiment of the present invention, and the assembly between the various parts of the pipeline system 1000 is simple and reliable.

[0028] Please refer to Figure 1 This utility model provides a pipeline system 1000, including a delivery pipeline 200 and a pipe connector assembly 100. The delivery pipeline 200 includes a main pipeline 201 and a secondary branch pipeline 202, which are connected by the pipe connector assembly 100. The secondary branch pipeline 202 is correspondingly arranged with a battery pack.

[0029] The material of the conveying pipeline 200 can be metal, high-strength plastic, ceramic, etc. Metal materials include aluminum, aluminum alloy, stainless steel, etc., and plastics include polyethylene, polypropylene, polyvinylidene fluoride, etc., without limitation. The main pipeline 201 or the secondary branch pipeline 202 can be a one-piece structure, that is, the main pipeline 201 or the secondary branch pipeline 202 is a one-piece structure manufactured by a one-piece molding process. The one-piece molding process can be stamping, casting, etc., without limitation.

[0030] Optionally, at least a portion of the main path 201 extends along a first direction Z, one end of the secondary branch 202 is used to communicate with the battery pack, and the end of the secondary branch 202 away from the battery pack is connected to the main path 201 through the pipe connector assembly 100.

[0031] Optionally, there may be multiple secondary branches 202, which are arranged sequentially and at intervals along the first direction Z. Optionally, there may also be multiple pipe fitting assemblies 100, each corresponding to one of the multiple secondary branches 202. Optionally, for the multiple pipe fitting assemblies 100 arranged sequentially along the first direction Z, the inner diameters of the mating pipes 20 within each pipe fitting assembly 100 may not all be the same. Optionally, for the multiple pipe fitting assemblies 100 arranged sequentially along the first direction Z, the inner diameter of the mating pipes 20 within each pipe fitting assembly 100 can change monotonically (i.e., gradually increase or gradually decrease), and some of the mating pipes 20 may also have the same inner diameter; selection is based on actual needs and is not specifically limited.

[0032] In one specific embodiment, the main path 201 includes multiple flow segments, and two adjacent flow segments are respectively connected to the pipe joint 10 of the same pipe joint assembly 100. The connecting pipe 11 of the pipe joint assembly 100 is also connected to the secondary branch 202.

[0033] The pipeline system 1000 in this embodiment of the present invention, by adopting the pipe fitting assembly 100 in this embodiment of the present invention, wherein the pipe fitting assembly 100 is marked with the installation position information of the pipe fitting assembly 100, can improve the assembly accuracy and installation efficiency of the pipe fitting assembly 100 in the pipeline system 1000.

[0034] Please refer to Figures 2 to 4This utility model embodiment also provides a pipe fitting assembly 100, including a pipe fitting 10 and a mating pipe 20 in this utility model embodiment. The mating pipe 20 in this utility model embodiment will be described in detail below.

[0035] Please refer to Figure 3 and Figure 4 This utility model embodiment provides a mating tube 20, including a tube body 21 and a marking structure 22, wherein the tube body 21 is used to mate and connect with the tube connector 10.

[0036] The cross-section of the tube body 21 can be approximately circular, square, triangular, or a regular polygon, without limitation. The material of the tube body 21 can be metal, high-strength plastic, ceramic, etc. Metal materials include aluminum, aluminum alloy, stainless steel, etc., and plastics include polyethylene, polypropylene, polyvinylidene fluoride, etc., without limitation. The tube body 21 and the marking structure 22 can be an integral structure, that is, the tube body 21 and the marking structure 22 are an integral structure manufactured by a one-piece molding process; or the tube body 21 and the marking structure 22 can also be separate structures, which are connected and fixed by welding, bonding, snap-fitting, screwing, riveting, magnetic connection, etc., without limitation.

[0037] The marking structure 22 is disposed on the outer periphery of the pipe body 21. The marking structure 22 includes an adjusting member 23 and a marking member 24. The adjusting member 23 is used to adjust the state of the marking member 24 so that the marking member 24 is used to mark the installation position information of the mating pipe 20 in the pipeline system 1000.

[0038] Optionally, the number of adjusting element 23 and marking element 24 can be one or more, without limitation.

[0039] For battery systems, mating pipes 20 with the same inner diameter can be used in different battery clusters and different layers of battery packs within a battery cluster. The same layer of battery packs in multiple battery clusters can use mating pipes 20 with the same inner diameter, or mating pipes 20 with different inner diameters, making the assembly piping relatively complex. During assembly, workers need to check the installation position information of a large number of similar mating pipes 20, which can easily lead to installation errors.

[0040] The installation location information is used to display the installation position of the mating pipe 20 in the piping system 1000. Optionally, the battery device includes a single battery cluster, which comprises multiple battery packs stacked sequentially in the first direction Z. In this case, the installation location information is used to display which layer of the battery cluster the mating pipe 20 is installed on, and the installation position of the mating pipe 20 in the piping system 1000 can be located by using the position information in the first direction Z.

[0041] Alternatively, the battery device may include multiple battery clusters arranged sequentially in the second direction X. Each battery cluster includes multiple battery packs, and the battery packs within each cluster are stacked sequentially along the first direction Z. With this arrangement, the multiple battery packs within the battery device can be roughly arranged in a multi-row, multi-column array. The installation position information of the mating pipe 20 can be understood as the coordinate information of the mating pipe 20 in the horizontal and vertical coordinate system formed by the first direction Z and the second direction X. The installation position of the mating pipe 20 within the piping system 1000 can be located using the position information in both directions.

[0042] Optionally, the battery device includes multiple battery clusters, which can be arranged in a multi-row, multi-column array along the second direction X and a third direction (not shown). Each battery cluster includes multiple battery packs, and the battery packs within each cluster are stacked sequentially along the first direction Z, wherein the first direction Z, the second direction X, and the third direction are perpendicular to each other. In this case, the installation position information of the mating pipe 20 can be understood as the coordinate information of the mating pipe 20 in a three-dimensional coordinate system composed of the first direction Z, the second direction X, and the third direction. The installation position of the mating pipe 20 within the piping system 1000 can be located using the position information in the three directions.

[0043] In some other embodiments, the installation location information may also be any other feasible information that can show the installation location of the mating pipe 20 in the piping system 1000, and there are no specific limitations.

[0044] In some other embodiments, in addition to identifying the installation location information of the mating pipe 20 in the piping system 1000, the marking structure 22 can also be used to identify other information of the mating pipe 20, such as the size and material of the mating pipe 20, etc., without any specific limitation.

[0045] In this embodiment of the utility model, the mating pipe 20, by setting a pipe body 21 and an identification structure 22, can identify the installation position information of the mating pipe 20 in the pipeline system 1000. During installation, the operator only needs to install the mating pipe 20 in the corresponding position of the pipeline system 1000 according to the identified installation position information, which can improve the assembly accuracy and installation efficiency of the mating pipe 20 in the pipeline system 1000. In addition, for multiple mating pipes 20 of the same size, the adjusting component 23 can adjust the installation position information displayed by the identification component 24, so that the mating pipe 20 can be conveniently installed in different installation positions of the pipeline system 1000. During production, there is no need to produce mating pipes 20 with multiple markings, saving costs and facilitating mass production.

[0046] In one implementation, such as Figure 2As shown, the pipe connector 10 includes a connecting pipe 11, at least a portion of the pipe body 21 extends into the connecting pipe 11, and the outer diameter of the pipe body 21 is the same as the inner diameter of the connecting pipe 11, with the marking structure 22 exposed in the pipe connector 10.

[0047] Optionally, the pipe connector 10 is a tee (i.e., the pipe connector 10 has three openings, at least one of which is an inlet and at least one of which is an outlet; the specific opening is not limited). The pipe connector 10 includes a main pipe 12 and a connecting pipe 11. The main pipe 12 extends generally along the first direction Z and is connected to the main channel 201 of the conveying pipeline 200. The extending direction of the connecting pipe 11 forms an angle with the first direction Z. One end of the connecting pipe 11 is connected to the main pipe 12, and the other end is connected to the pipe body 21 of the mating pipe 20. Optionally, the connecting pipe 11 extends generally along the second direction X.

[0048] Optionally, the pipe body 21 is connected and fixed to the connecting pipe 11. The pipe fitting 10 and the mating pipe 20 can be connected and fixed by means of bonding, snap-fitting, screwing, riveting, plugging, etc., without restriction.

[0049] The pipe body 21 of the fitting pipe 20 is connected to the connecting pipe 11 of the pipe connector 10, and the outer diameter of the pipe body 21 is the same as the inner diameter of the connecting pipe 11. By using fitting pipes 20 with different inner diameters, the inner diameter at the interface of the pipe connector assembly 100 can be adjusted, thereby adjusting the flow distribution of the battery pack inlet pipe through the pipe connector assembly 100.

[0050] Optionally, the inner diameter of the tube body 21 is D1 (not shown in the figure), and the specific value of D1 can be 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, or 14mm. In some other embodiments, the inner diameter of the tube body 21 can also be other sizes as needed, and there are no specific limitations.

[0051] In some other embodiments, the inner diameter of the tube body 21 is not all the same. Optionally, the inner diameter of the tube body 21 may gradually increase or decrease from the end where it is connected to the pipe connector 10 to the end away from the pipe connector 10, without any specific limitation.

[0052] In some other embodiments, at least a portion of the tube body 21 is fitted onto the outer peripheral surface of the connecting pipe 11, and the inner diameter of the end of the tube body 21 away from the connecting pipe is larger than the inner diameter of the connecting pipe 11. That is, the fitting tube 20 can be used to increase the flow rate of the pipe fitting assembly 100, and there are no specific limitations.

[0053] When the pipe fitting assembly 100 in this embodiment of the present invention is applied in the pipeline system 1000, multiple pipe fitting assemblies 100 can use pipe fittings 10 of the same size. The flow rate can be adjusted by changing the inner diameter of the mating pipe 20. The structure is simple and easy to assemble.

[0054] In one implementation, such as Figure 2 and Figure 3 As shown, there are multiple markers 24. Optionally, the multiple markers 24 can be placed close together or spaced apart, without limitation. Optionally, the multiple markers 24 can be arranged sequentially along the axial direction of the pipe body 21 or along the axial direction, without limitation.

[0055] In one implementation, such as Figures 2 to 4 As shown, the marking element 24 is annular and protrudes from the outer circumferential surface of the pipe body 21, with multiple marking elements 24 tightly attached to the axial direction of the pipe body 21. Optionally, the marking structure 22 is located at the end of the pipe body 21 away from the pipe connector 10. With this configuration, the marking structure 22 protrudes from the pipe body 21, and during the assembly of the pipe body 21 and the connecting pipe 11, the marking structure 22 can play a positioning role, ensuring that the mating pipe 20 and the pipe connector 10 are installed in place.

[0056] In other embodiments, multiple markers 24 may also be sequentially arranged on the end face of the pipe body 21 facing away from the pipe connector 10. The multiple markers 24 may be sequentially arranged along the circumference or radial direction of the end face. The multiple markers 24 may be closely attached or spaced apart, without limitation.

[0057] In one implementation, such as Figure 2 As shown, one of the outermost marking elements 24 abuts against the pipe connector 10, while another marking element 24 is flush with the end face of the pipe body 21 furthest from the pipe connector 10. Optionally, when the mating pipe 20 is inserted into the pipe connector 10, the marking element 24 closest to the pipe connector 10 abuts against the connecting pipe 11 of the pipe connector 10, serving a positioning purpose; and the marking element 24 furthest from the pipe connector 10 is flush with the end face of the pipe body 21 furthest from the pipe connector 10, which can save the overall length of the mating pipe 20 and reduce costs.

[0058] The plurality of marking elements 24 include a first marking element 241 and a second marking element 242. The first marking element 241 is used to mark the installation position information of the mating tube 20 in the first direction Z, and the second marking element 242 is used to mark the installation position information of the mating tube 20 in the second direction X.

[0059] Optionally, the battery device includes multiple battery clusters, which are sequentially arranged in the second direction X; each battery cluster includes multiple battery packs, which are sequentially stacked along the first direction Z. With this arrangement, the multiple battery packs within the battery device can be arranged in a roughly multi-row, multi-column array. The installation position information of the mating pipe 20 in the first direction Z and the second direction X can be understood as the coordinate information of the mating pipe 20 in the horizontal and vertical coordinate system formed by the first direction Z and the second direction X. The installation position of the mating pipe 20 within the piping system 1000 can be located using its position in these two directions.

[0060] Optionally, multiple battery clusters can also be arranged in a multi-row, multi-column array in the second direction X and the third direction. In this case, the multiple markers 24 also include a fourth marker, which is used to mark the installation position information of the mating pipe 20 in the third direction. That is, the installation position information of the mating pipe 20 can be understood as the coordinate information of the mating pipe 20 in a three-dimensional coordinate system composed of the first direction Z, the second direction X, and the third direction. The installation position of the mating pipe 20 in the pipeline system 1000 can be located by the position in each direction.

[0061] With this configuration, the first marker 241 and the second marker 242 can identify the installation position information of the mating pipe 20 in two directions, which facilitates the installation by the staff and can improve the assembly accuracy and installation efficiency of the mating pipe 20 in the pipeline system 1000.

[0062] In some other embodiments, an identifier 24 may be used to simultaneously identify the installation position information of the mating tube 20 in the first direction Z and the second direction X, without any specific limitation.

[0063] In one embodiment, the plurality of marking elements 24 further includes a third marking element 243, which is used to mark the inner diameter of the tube body 21.

[0064] Optionally, the third identification element 243 may identify the inner diameter of the mating tube 20 by a code. For example, the mating tube 20 with an inner diameter of 7mm, 8mm, 10mm, or 14mm may be identified by the codes 1, 2, 3, and 4, or by a code commonly used by those skilled in the art. Alternatively, the third identification element 243 may also directly identify the inner diameter data of the mating tube 20 without restriction.

[0065] With this setup, before installing the mating pipe 20, the operator can pre-plan the installation position of the mating pipe 20 based on its inner diameter, and adjust the first marker 241 and the second marker 242 using the adjusting component 23 to display the installation position information of the mating pipe 20, which facilitates subsequent installation. When installing the mating pipe 20, the operator can verify the accuracy of the installation position of the mating pipe 20 by checking its inner diameter.

[0066] Furthermore, since the outer diameters of mating pipes 20 with different inner diameters are the same (which facilitates assembly with pipe fittings 10 of the same size), marking the inner diameter of the mating pipes 20 on the marking structure 22 also makes it easier for workers to identify mating pipes 20 with different inner diameters, thereby improving assembly accuracy and installation efficiency.

[0067] In one specific embodiment, such as Figures 2 to 4As shown, the second marking element 242, the first marking element 241 and the third marking element 243 are sequentially disposed on the outer peripheral surface of the tube body 21 and are tightly attached to the tube body 21 along the axial direction.

[0068] In one specific implementation, such as Figure 1 As shown, the battery device includes a first battery cluster, which comprises eight battery packs stacked sequentially along the first direction Z, with the battery packs connected in series. The inlet and outlet of the main pipeline 201 are at the top layer (i.e., the uppermost layer of the battery cluster in the first direction Z). The top layer has low flow resistance, resulting in a larger flow rate for the battery packs. To ensure a uniform flow distribution among the battery packs in each layer, a matching pipe 20 with a smaller inner diameter should be selected. Based on the flow optimization results, among the selected pipe fitting assemblies 100, the inner diameters of the pipe fitting assemblies 100 from the top layer to the bottom layer are 7mm, 8mm, 10mm, 10mm, 12mm, 14mm, 14mm, and 14mm, respectively.

[0069] Optionally, the inner diameter of the connecting pipe 11 of the pipe connector 10 is 14mm. For the lowermost pipe connector assembly 100 with an inner diameter of 14mm, it is not necessary to assemble the mating pipe 20 on the pipe connector 10. For other pipe connector assemblies 100, four mating pipes 20 with inner diameters of 7mm, 8mm, 10mm, and 12mm are required. Based on the battery cluster serial number, the number of battery pack layers, and the inner diameter, the installation position information and inner diameter information displayed on the marking element 24 are adjusted by the adjusting element 23. For example, for a 7mm inner diameter fitting tube 20, multiple markings 24 sequentially display C1, F1, and D7, indicating that the fitting tube 20 is installed in the first battery cluster and the first layer of battery pack (counting from top to bottom), and the inner diameter of the fitting tube 20 is 7mm; for a 8mm inner diameter fitting tube 20, multiple markings 24 sequentially display C1, F2, and D8, indicating that the fitting tube 20 is installed in the first battery cluster and the second layer of battery pack, and the inner diameter of the fitting tube 20 is 8mm. The marking information for the other two inner diameter fitting tubes 20 can be referred to the above and will not be repeated.

[0070] Optionally, during the installation of the piping system 1000, pipe fittings 10 of the same size are first installed on the main line 201, and then the matching pipe 20 is installed according to the positioning of the marking structure 22. The end of the matching pipe 20 away from the pipe fitting 10 is connected to the secondary branch line 202, and the secondary branch line 202 is connected to the battery pack.

[0071] With this setup, the supplier of the piping system 1000 can produce commonly used pipe fitting assemblies 100 in advance. Depending on the optimization results of the flow resistance of different projects, the pipe fittings 10 and matching pipes 20 with different inner diameters can be combined and assembled in different piping systems 1000, saving production time.

[0072] In one implementation, such as Figure 3 and Figure 4 As shown, the sign 24 includes a display frame 244 and a display part 245. The display frame 244 encloses an opening 246, and the display part 245 is sequentially provided with multiple different position information. At least a portion of the display part 245 is exposed through the opening 246.

[0073] The shapes of the display frame 244 and the opening 246 can be square, circular, triangular, sector-shaped, irregular, etc., without any specific restrictions. Optionally, the shapes of the display frame 244 and the opening 246 can be the same or different, without any restrictions.

[0074] Optionally, the sign 24 has a receiving space 247, an opening 246 communicating with the receiving space 247, and a display 245 being received in the receiving space 247 and being able to move relative to the opening 246.

[0075] The display portion 245 can be generally strip-shaped, block-shaped, etc., without limitation. In a specific embodiment, when the marking member 24 is annular and protrudes from the outer peripheral surface of the tube body 21, the display portion 245 can extend approximately along an arc and be set to conform to the curvature of the outer peripheral surface of the tube body 21. Multiple different position information are sequentially arranged on the display portion 245 along the arc extension direction. The display portion 245 can rotate around the circumference of the tube body 21 so that different position information is exposed in the opening 246, thereby marking the installation position information of the mating tube 20.

[0076] The adjusting member 23 is connected to the display unit 245, which is used to rotate under the adjustment of the adjusting member 23 so that the corresponding position information is exposed from the opening 246.

[0077] Optionally, the display unit 245 and the adjusting member 23 can be directly connected or indirectly connected, without limitation. Optionally, the display unit 245 and the adjusting member 23 can be connected by a transmission connection, specifically a mechanical transmission connection, an electric transmission connection, or any other feasible transmission connection method, without limitation. In some other embodiments, the display unit 245 and the adjusting member 23 can also be connected by any other feasible method, without specific limitation.

[0078] Optional, such as Figure 5 As shown, the marking component 24 also includes a transmission part 25, which is connected to both the display part 245 and the adjusting member 23. The transmission part 25 can drive the display part 245 to move under the action of the adjusting member 23. Specifically, the transmission part 25 can convert the rotation of the adjusting member into the rotation of the display part 245, or the transmission part 25 can convert the sliding of the adjusting member into the rotation of the display part 245, or the transmission part 25 can be any other feasible conversion method, without any specific limitation.

[0079] With this configuration, the display unit 245 can be moved by adjusting the adjustment component 23 so that the installation position information of the mating pipe 20 is exposed from the opening 246. This allows the installation position information of the mating pipe 20 in the piping system 1000 to be identified. Furthermore, for the same mating pipe 20, the information displayed on its identification unit can be adjusted according to actual needs. During production, it is not necessary to produce multiple mating pipes 20 with different identifications, which saves costs and facilitates mass production.

[0080] Understandably, for the third marker 243, the display unit 245 is sequentially provided with multiple different inner diameter dimensions. Its operation method is similar to that described above, and can be referred to accordingly without further explanation.

[0081] Optionally, each identification element 24 has a label 249 affixed to its outer surface to display the information displayed on the identification element 24. For example, the label 249 of the first identification element 241 may be marked "Layer," indicating that the first identification element 241 is used to identify which layer of the piping system 1000 the mating pipe 20 is used in; the label 249 of the second identification element 242 may be marked "Cluster," indicating that the second identification element 242 is used to identify which battery cluster of the piping system 1000 the mating pipe 20 is used in; and the label 249 of the third identification element 243 may be marked "Inner Diameter," indicating that the third identification element 243 is used to identify the inner diameter of the mating pipe 20.

[0082] In one implementation, such as Figure 3 As shown, the display frame 244 includes a mounting surface 248, and an adjusting member 23 is movably connected to the mounting surface 248. When the adjusting member 23 extends out of the mounting surface 248, the adjusting member 23 rotates to adjust the rotation of the display unit 245.

[0083] Optionally, the adjusting member 23 can rotate about an axis and drive the display unit 245 to rotate via the transmission unit 25. In some possible embodiments, the adjusting member 23 rotates clockwise to adjust the display unit 245 to rotate clockwise, or the adjusting member 23 rotates counterclockwise to adjust the display unit 245 to rotate clockwise, without limitation.

[0084] The adjusting member 23 is also used to move toward the mounting surface 248 to fix the display unit 245. Optionally, such as... Figure 5 As shown, the marking member 24 also includes an elastic part 26 and a locking part 27, and the adjusting member 23 is connected to the locking part 27 through the elastic part 26.

[0085] When the adjusting member 23 is pressed, the adjusting member 23 moves toward the mounting surface 248 and compresses the elastic part 26. The elastic part 26 is pressed and applies pressure to the locking part 27. Under the pressure of the elastic part 26, the locking part 27 fixes the display part 245, preventing the display part 245 from rotating due to accidental contact during the movement of the mating tube 20 or during assembly, thereby improving assembly accuracy.

[0086] Optionally, when the adjusting member 23 is pressed and its end face is flush with the mounting surface 248, such as Figure 4 As shown, the position of the display unit 245 is fixed at this time, and the required installation position information is exposed from the opening 246.

[0087] In other embodiments, any other feasible connection structure may be used between the adjustment member 23 and the display unit 245, without limitation.

[0088] In one implementation, such as Figure 6 As shown, the identification component 24 includes a display screen 28, and the adjustment component 23 is electrically connected to the display screen 28 and is used to adjust the display screen 28 to display the installation position information of the mating pipe 20 in the piping system 1000.

[0089] The adjustment component 23 and the display screen 28 can be connected or spaced apart, without restriction.

[0090] In this embodiment, the marker 24 also includes a circuit board 29, and both the adjusting member 23 and the display screen 28 are electrically connected to the circuit board 29. In a specific implementation, the display screen 28 is used to display the installation position information of the mating pipe 20 in the piping system 1000. When the operator needs to adjust the information displayed on the display screen 28, they press or rotate the adjusting member 23. The movement of the adjusting member 23 is converted into an electrical signal and transmitted to the circuit board 29. After processing, the circuit board 29 transmits the corresponding control signal to the display screen 28, so that the display screen 28 displays the required installation position information.

[0091] In this embodiment, the signal transmission method between the adjustment member 23 and the display screen 28 can also adopt any feasible transmission method in the art, and there is no specific limitation.

[0092] With this setup, the installation position information displayed on the display screen 28 can be adjusted by adjusting the adjustment component 23. For the same mating pipe 20, the information displayed on its marking section can be adjusted according to actual needs. During production, there is no need to produce multiple mating pipes 20 with different markings, saving costs and facilitating mass production.
