[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0052] Please refer to Figure 1 , this application proposes a heating, ventilation and air conditioning (HVAC) system, which includes a refrigerant switching device 300, an outdoor unit (not shown in the figure), and a plurality of indoor units (not shown in the figure). Among them, the outdoor unit and the plurality of indoor units are both connected to the refrigerant switching device 300, and the refrigerant can circulate in the outdoor unit, the refrigerant switching device 300, and the plurality of indoor units to achieve the effect of one outdoor unit driving multiple indoor units, that is, it can achieve the effect of one outdoor unit driving multiple indoor units through the refrigerant switching device 300.

[0053] Specifically, the outdoor unit is usually arranged outside the building and includes a compressor, a condenser, an evaporator, etc., for processing the refrigerant. The indoor unit is usually arranged inside the building and includes a heat exchanger. There are usually multiple target spaces in the building, and a plurality of indoor units are arranged in the multiple target spaces one by one. In this way, one indoor unit can adjust the air in one target space to achieve a cooling or heating effect. The refrigerant switching device 300 can select a suitable refrigerant to be delivered to the heat exchanger in the indoor unit according to the cooling or heating needs of a certain target space, realize the conversion of different modes of the indoor unit, and make the indoor unit in a cooling or heating mode.

[0054] Please continue to refer to Figure 1 , in some embodiments, the refrigerant switching device 300 includes a housing 330, a pipeline assembly 310, and a fixing assembly 100 of the pipeline assembly 310. The housing 330 is provided with an installation cavity 340, and the pipeline assembly 310 and the fixing assembly 100 are both arranged in the installation cavity 340.

[0055] The housing 330 can be generally box-shaped. For example, the housing 330 can be set as a cuboid-shaped structure with a hollow interior so that an installation cavity 340 can be configured inside itself. Of course, the shape of the housing 330 can be configured into any other shape according to the installation environment or related design, and this embodiment does not limit this. The housing 330 can be made of a metal plate or a flame-retardant resin plate material, which has high strength and supportability, can not only play a good protective role for internal devices such as the pipeline assembly 310, but also play a flame-retardant role in the event of a combustion accident.

[0056] The pipeline assembly 310 includes a switching pipeline and a connecting pipeline 320. Among them, the switching pipeline is connected to the outdoor unit and includes a liquid refrigerant pipeline, a high-pressure gaseous refrigerant pipeline, and a low-pressure gaseous refrigerant pipeline. The connecting pipeline 320 is connected to the indoor unit, specifically, it is communicated with the heat exchanger of the indoor unit, and includes a liquid pipeline and a gas pipeline. The connecting pipeline 320 includes multiple paths, and the multiple connecting pipelines 320 are arranged at intervals, that is, the multiple connecting pipelines 320 are arranged in the installation cavity 340 at intervals. One of the connecting pipelines 320 is correspondingly communicated with one indoor unit. For example, one liquid pipeline is communicated with the indoor unit.

[0057] It can be understood that during the actual operation of the HVAC system, when the indoor unit is in the cooling mode, at this time the liquid refrigerant pipeline will be communicated with the liquid pipeline, and the gas pipeline is communicated with the low-pressure gaseous refrigerant pipeline. Specifically, first, the liquid refrigerant will flow from the indoor unit to the liquid refrigerant pipeline, then from the liquid refrigerant pipeline to the liquid path pipeline, and then from the liquid path pipeline to the heat exchanger of the indoor unit for heat exchange to achieve heat absorption. During the heat absorption process, the liquid refrigerant will be converted into low-pressure gaseous refrigerant, and will flow from the heat exchanger to the gas pipeline, then from the gas pipeline to the low-pressure gaseous refrigerant pipeline, and finally from the low-pressure gaseous refrigerant pipeline to the outdoor unit; when the indoor unit is in the heating mode, at this time the high-pressure gaseous refrigerant pipeline is communicated with the gas pipeline, and the liquid pipeline and the liquid refrigerant pipeline are communicated. Specifically, first, the high-pressure gaseous refrigerant will flow from the indoor unit to the high-pressure gaseous refrigerant pipeline, then from the high-pressure gaseous refrigerant pipeline to the gas pipeline, and then from the gas pipeline to the heat exchanger of the indoor unit for heat exchange to achieve heat release. During the heat release process, the high-pressure gaseous refrigerant pipe will be converted into liquid refrigerant, and will flow from the heat exchanger to the liquid pipeline, then from the liquid pipeline to the liquid refrigerant pipeline, and finally from the liquid refrigerant pipeline to the outdoor unit.

[0058] The fixing component 100 is used to fix the multiple connecting pipelines 320, so that during the handling or transportation of the refrigerant switching device 300, etc., it is not easy for the adjacent two connecting pipelines 320 to collide due to vibration and cause position deviation, and thus the possibility of damage caused by the collision of the connecting pipeline 320 can be reduced.

[0059] In order to improve the fixing efficiency of the fixing component 100 for the multiple connecting pipelines 320 during the overall assembly process of the refrigerant switching device 300 by the staff, please refer to Figures 2 to 3 In some embodiments, the fixing component 100 includes a support beam 10 and a fixing member 30.

[0060] The support beam 10 can be in a long strip shape and extend along the arrangement direction of the multiple connecting pipelines 320. The support beam 10 can be made of metal material to have high strength and support. Among them, the support beam 10 is used to support the multiple connecting pipelines 320 to prevent the multiple connecting pipelines 320 from falling and being damaged.

[0061] The fixing member 30 may be generally elongated as a whole and extend along the extending direction of the support beam 10. The fixing member 30 may include at least one of a metal member and a plastic member, and this embodiment does not limit this. Among them, the fixing member 30 is used to press the multi-way connection pipeline 320 against the support beam 10 to cooperate with the support beam 10 to fix the multi-way connection pipeline 320.

[0062] In summary, the technical solution of this embodiment realizes the fixation and limitation of the multi-way connection pipeline 320 by adopting the cooperation of the support beam 10 and the fixing member 30, that is, by pressing the multi-way connection pipeline 320 against the support beam 10 through the fixing member 30. Thereby, the stability of the position of the multi-way connection pipeline 320 can be improved, and it is possible to avoid the situation where the adjacent two-way connection pipelines 320 collide with each other and cause damage to the connection pipeline 320 during the handling, transportation, or use of the refrigerant switching device 300. At the same time, it also avoids the situation where friction occurs between the connection pipeline 320 of the refrigerant switching device 300 and the support beam 10, resulting in damage to the connection pipeline 320. In this way, it can play a good protective role for the connection pipeline 320, thereby effectively reducing the risk of refrigerant leakage and reducing the noise generated during the operation of the refrigerant switching device 300.

[0063] Moreover, through the cooperation of the support beam 10 and the fixing member 30, the multi-way connection pipeline 320 can be fixed and limited at the same time. Compared with the form of fixing and limiting one-way connection pipeline 320 through a single fixing structure, this embodiment can better simplify the assembly process and effectively improve the assembly efficiency of the support beam 10, the fixing member 30, and the multi-way connection pipeline 320 in the workshop.

[0064] Please refer to Figures 1 to 2 , in some embodiments, the multi-way connection pipeline 320 includes multiple groups, and the multiple groups of multi-way connection pipelines 320 are arranged at intervals along the extending direction of the support beam 10 in the installation cavity 340. In this way, it is possible to realize that one outdoor unit drives more indoor units to be suitable for use scenarios with a larger number of target spaces.

[0065] Among them, the fixing member 30 includes multiple ones, and one fixing member 30 cooperates with the support beam 10 to fix one group of multi-way connection pipelines 320. In this way, through the cooperation of the multiple fixing members 30 and the support beam 10, the multi-way connection pipeline 320 can be fixed, facilitating the installation operation.

[0066] Please refer to Figure 1 , in some embodiments, the opposite ends of the support beam 10 along its extending direction are respectively connected to the opposite side walls of the installation cavity 340.

[0067] It can be understood that when the housing 330 has a box structure, the housing 330 includes a top plate, a bottom plate, and two side plates. Among them, the two side plates are arranged at intervals along the length direction of the housing 330. The top plate is connected between the two side plates, the bottom plate is connected between the two side plates, and the top plate and the bottom plate are arranged at intervals in the thickness direction of the housing 330. Among them, the top plate, the bottom plate, and the two side plates jointly enclose an installation cavity 340.

[0068] Specifically, the two opposite ends of the support beam 10 along its extension direction are respectively connected to the two side plates. In this way, the support beam 10 will be above the bottom plate and have no fixed connection relationship with the bottom plate. Based on this, when the support beam 10 supports the multi-way connection pipeline 320, the multi-way connection pipeline 320 is suspended above the bottom plate. Generally speaking, the bottom plate will exist as a water receiving tray of the refrigerant switching device 300 for receiving condensed water. Therefore, on the basis that the multi-way connection pipeline 320 is suspended above the bottom plate, when it is necessary to clean the water receiving tray, the water receiving tray can be directly disassembled, and the operation is very convenient.

[0069] Please refer to Figures 3 to 4 , in some embodiments, the fixing member 30 includes a connecting body 31 and a fixing body 33. The connecting body 31, as the connecting part of the fixing member 30, can be made of a metal material to ensure its own strength and improve the connection stability. The connecting body 31 extends along the extension direction of the support beam 10, and the connecting body 31 is connected to the support beam 10.

[0070] The fixing body 33, as the part of the fixing member 30 for fixing the multi-way connection pipeline 320, can be made of an elastic material or a metal material. Among them, the fixing body 33 is connected to the side of the connecting body 31 close to the support beam 10.

[0071] Among them, at least one of the fixing body 33 and the support beam 10 is formed with a plurality of fixing grooves 331. Specifically, it can be that the fixing body 33 is formed with a plurality of fixing grooves 331, or the support beam 10 is formed with a plurality of fixing grooves 331, or the fixing body 33 forms a plurality of first half grooves, and the support beam 10 forms a plurality of second half grooves. After the fixing member 30 presses the connection pipeline 320 against the support beam 10, the first half grooves and the second half grooves are in one-to-one correspondence and communicate to form the fixing grooves 331. Among them, one fixing groove 331 is used to abut and fix one-way connection pipeline 320. In this way, the connection pipeline 320 can be fixed and limited through the fixing grooves 331.

[0072] In this way, by connecting the connecting body 31 and fixedly connecting it to the connecting position of the support beam 10, the connecting body 31 can press the fixing body 33 against the multi-way connecting pipeline 320, so that the multi-way connecting pipeline 320 is directly and correspondingly fixed in a plurality of fixing grooves 331. Compared with the form in which the connecting body 31 is first connected to the cavity wall of the installation cavity 340, and then the fixing body 33 and the support beam 10 are aligned to fix the multi-way connecting pipeline 320, the form of this embodiment has fewer connecting steps and is convenient for connection. Of course, in other embodiments, the connecting body 31 can be connected to the side wall of the installation cavity 340 instead of being connected to the support beam 10, and this embodiment does not limit this.

[0073] Please refer to Figures 3 to 4 , further, the fixing body 33 is made of an elastic material, and a plurality of fixing grooves 331 are formed by recessing the surface of the fixing body 33 facing the support beam 10. In this way, on the basis of the connecting body 31 pressing against the fixing body 33, the elastic performance of the fixing body 33 can be utilized to achieve a better fixing effect on the connecting pipeline 320. At the same time, by forming the fixing grooves 331 with the fixing body 33 made of an elastic material, when the connecting pipeline 320 is abutted and fixed by the fixing grooves 331, the connecting pipeline 320 will not be damaged due to excessive friction with the groove wall surface of the fixing grooves 331, so that the protection effect on the connecting pipeline 320 can be improved, and the possibility of refrigerant leakage and other situations caused by the damage of the connecting pipeline 320 itself in the state of being abutted and fixed can be reduced.

[0074] Exemplarily, the material of the fixing body 33 can be specifically a rubber material, so that the fixing body 33 has good elasticity and stretchability. At the same time, it is also convenient for the fixing body 33 to be formed and processed into various shapes and sizes.

[0075] Please refer to Figures 3 to 4 , in some embodiments, at least part of the contour shape of the fixing groove 331 is adapted to the shape of the connecting pipeline 320, and at least part of the groove wall surface of the fixing groove 331 is used to fit and adhere to the outer peripheral surface of the connecting pipeline 320. Among them, it can be that the overall contour shape of the fixing groove 331 is adapted to the shape of the connecting pipeline 320, and the overall groove wall surface of the fixing groove 331 fits and adheres to the outer peripheral surface of the connecting pipeline 320. Or, it can be that part of the contour shape of the fixing groove 331 is adapted to the shape of the connecting pipeline 320, and part of the groove wall surface of the fixing groove 331 is used to fit and adhere to the outer peripheral surface of the connecting pipeline 320. This embodiment does not limit this.

[0076] It can be understood that the shape of the connecting pipeline 320 is usually a relatively regular circular shape. Correspondingly, at least part of the contour shape of the fixing groove 331 will be circular to achieve a profiling effect. In this way, by fitting the groove wall surface of the fixing groove 331 with the outer peripheral surface of the connecting pipeline 320, the abutting and fixing effect of the fixing groove 331 on the connecting pipeline 320 can be improved, thereby further ensuring the stability of the connecting pipeline 320 in the installation cavity 340.

[0077] Moreover, during the actual connection process, the connecting pipeline 320 needs to extend out of the housing 330 to be connected to the indoor unit. The connecting pipeline 320 usually includes multiple sub-pipelines welded together. There will always be a certain welding error during the welding process of the sub-pipelines, resulting in a position deviation of the connecting pipeline 320. Based on this technical problem, through the profiling groove wall surface design of the fixing groove 331, the fixing groove 331 can better position the connecting pipeline 320. Thus, even if there is a welding error in the connecting pipeline 320 itself, it can be limited to the preset position by the fixing groove 331, facilitating subsequent connection operations.

[0078] Please refer to Figures 3 to 4 In some embodiments, the fixing groove 331 includes a guiding groove section 3311 and a fixing groove section 3313. One end of the guiding groove section 3311 is open to form a slot opening for the connecting pipeline 320 to extend into the guiding groove section 3311. The fixing groove section 3313 communicates with the other end of the guiding groove section 3311 and is used to abut and fix the connecting pipeline 320.

[0079] Among them, the guiding groove section 3311 is flared in the direction from the fixing groove section 3313 to the guiding groove section 3311, so that the groove wall surface of the guiding groove section 3311 can guide the connecting pipeline 320 into the fixing groove section 3313. It can be understood that the groove wall surface of the guiding groove section 3311 can be an inclined surface or an arc surface to better guide the connecting pipeline 320 into the fixing groove section 3313, so that the connecting pipeline 320 can enter the fixing groove 331 more smoothly to be fixed by the fixing groove 331, facilitating the operation of the staff.

[0080] Combining the above two embodiments, further, the contour shape of the fixing groove section 3313 is adapted to the shape of the connecting pipeline 320, and the groove wall surface of the fixing groove section 3313 is adapted to and fits with the outer peripheral surface of the connecting pipeline 320. In this way, the abutting and fixing effect can be improved through the profiling design of the fixing groove section 3313, and the connecting pipeline 320 can be limited and positioned.

[0081] Please refer to Figures 3 to 4, in some embodiments, the fixing body 33 includes a plurality of fixing elastic parts 333. Among them, the plurality of fixing elastic parts 333 are split components, and each fixing elastic part 333 is generally cube-shaped. The plurality of fixing elastic parts 333 are arranged at intervals along the extending direction of the connecting body 31, and a fixing groove 331 is correspondingly formed in one fixing elastic part 333.

[0082] In this way, compared with the form that the fixing body 33 is a long strip-shaped integral component, each fixing elastic part 333 can ensure its own strength to better abut and fix the connecting pipeline 320, and can also facilitate the individual molding of each fixing elastic part 333, which is convenient for workshop molding and manufacturing.

[0083] Please refer to Figures 4 to 6 , further, each fixing elastic part 333 is detachably connected to the connecting body 31. In this way, if a certain fixing elastic part 333 is damaged or its elastic performance weakens due to long-term use, the fixing elastic part 333 can be disassembled and replaced, extending the service life of the fixing body 33. Among them, the specific detachable connection form between the fixing elastic part 333 and the connecting body 31 can be snap connection 3331 or threaded connection and so on. This embodiment does not limit this.

[0084] Of course, the present application is not limited to this. Each fixing elastic part 333 can also be fixedly connected to the connecting body 31 to improve the firmness of the connection between the fixing elastic part 333 and the connecting body 31.

[0085] Please refer to Figures 4 to 6 , in some embodiments, the fixing elastic part 333 is provided with a snap 3331, and the connecting body 31 is provided with a slot 311. The snap 3331 is engaged with the slot 311 to make the fixing elastic part 333 snap onto the connecting body 31. In this way, through the snap connection between the snap 3331 and the slot 311, the stability of the connection between the fixing elastic part 333 and the connecting body 31 can be improved, making the fixing elastic part 333 not easy to loosen, and no additional tools are required for connection or disassembly, and the operation is more convenient.

[0086] Optionally, the connecting body 31 is provided with a snap 3331, and the fixing elastic part 333 is provided with a slot 311 for snap connection with the snap 3331. This embodiment does not limit this.

[0087] And in order to extend the service life of the snap 3331, please refer to Figures 4 to 6, Further, the card slot 311 includes a sliding groove section 3111 and a card slot section 3113 that are connected and communicate with each other. The notch of the sliding groove section 3111 is larger than the notch of the card slot section 3113. Among them, the buckle 3331 can extend into the sliding groove section 3111 and slide along the sliding groove section 3111 into the card slot section 3113 to be clamped with the card slot section 3113.

[0088] It can be understood that the size of the buckle 3331 matches or is close to the size of the notch of the sliding groove section 3111, so that when the buckle 3331 extends into or out of the sliding groove section 3111, it will not contact or contact less with the sliding groove section 3111, so that the buckle 3331 can not undergo elastic deformation or the degree of elastic deformation is small. And the notch size of the card slot section 3113 is smaller than the size of the buckle 3331, so that the buckle 3331 can be clamped in the card slot section 3113.

[0089] Based on the above technical solution, this embodiment can avoid a large degree of elastic deformation of the buckle 3331 during the process of extending into or out of the card slot 311, and further avoid damage to the buckle 3331 itself or poor elastic performance due to multiple large degrees of elastic deformation, effectively extending the service life of the buckle 3331.

[0090] Please refer to Figures 4 to 6 , Further still, at least part of the outer peripheral surface of the buckle 3331 is formed with a guiding inclined surface 3331a, so that the buckle 3331 is generally in the shape of a frustum of a cone. Among them, the outer peripheral surface of the buckle 3331 may be integrally formed with the guiding inclined surface 3331a, or a part of the outer peripheral surface is formed with the guiding inclined surface 3331a, and this embodiment does not limit this.

[0091] The guiding inclined surface 3331a is used for guiding cooperation with the groove side wall of the sliding groove section 3111 during the process of the buckle 3331 extending into the sliding groove section 3111. In this way, the buckle 3331 can extend into the sliding groove section 3111 more smoothly, facilitating the clamping cooperation operation between the buckle 3331 and the card slot 311.

[0092] Please refer to Figures 3 to 5 , In some embodiments, the connecting body 31 includes a main body portion 313 and at least two connecting portions 315. It can be understood that the main body portion 313 is the main part of the connecting body 31 and is generally arranged in a long strip shape.

[0093] The connecting portion 315 is the part of the connecting body 31 for connecting with the support beam 10. Among them, the connecting portion 315 can be in the structural form of connecting feet. Among them, the two connecting portions are respectively connected to opposite ends of the main body portion 313 along its extending direction, and are both connected to the support beam 10. In this way, both opposite ends of the main body portion 313 along its extending direction are indirectly connected to the support beam 10 through the connecting portion 315, so as to improve the stability of the connection between the connecting body 31 and the support beam 10, and further enable the connecting body 31 to better press the fixing body 33 against the connecting pipeline 320.

[0094] Please continue to refer to Figures 3 to 5 Furthermore, a first connection hole 3151 is provided on each connecting portion 315, and a second connection hole 11 corresponding to the number of the first connection holes 3151 is provided on the support beam 10. The fixing assembly 100 further includes at least two fasteners (not shown in the figure).

[0098] It can be understood that when the connecting body 31 is made of a metal material, specifically a sheet metal part for example, the first flanging portion 317 can be formed by processes such as stamping, which is convenient for manufacturing and production. On the basis of providing the first flanging portion 317, first, since the first flanging portion 317 is arranged at an angle with the main body portion 313, the first flanging portion 317 can strengthen the strength of the main body portion 313, so that the overall strength of the connecting body 31 is increased. Secondly, since the first flanging portion 317 is connected to the outer side of the main body portion 313, the first flanging portion 317 can also play a limiting effect on the connecting body 31, such as playing a limiting role on a plurality of fixed elastic portions 333, ensuring the stability of the connection between the fixed elastic portions 333 and the main body portion 313. Furthermore, since the first flanging portion 317 extends along the extending direction of the main body portion 313, during the actual installation process of the fixing body 33, the fixed elastic portions 333 can be guided by the first flanging portion 317 along the extending direction of the first flanging portion 317 to the installation position where they need to stay, so as to facilitate the staff to install the plurality of fixed elastic portions 333 of the fixing body 33 onto the main body portion 313 of the connecting body 31.

[0099] Please refer to Figures 4 to 5 , in some embodiments, the connecting body 31 further includes a second flanging portion 319, and the second flanging portion 319 is connected to the outer side of the connecting portion 315 and is arranged at an angle.

[0100] It can be understood that when the connecting body 31 is made of a metal material, specifically a sheet metal part for example, the second flanging portion 319 can be formed by processes such as stamping, which is convenient for manufacturing and production. On the basis of providing the second flanging portion 319, first, since the second flanging portion 319 is arranged at an angle with the main body portion 313, the second flanging portion 319 can strengthen the strength of the main body portion 313, so that the overall strength of the connecting body 31 is increased.

[0101] Please refer to Figures 4 to 5 , in some embodiments, the connecting body 31 further includes a first flanging portion 317 and a second flanging portion 319. The first flanging portion 317 is connected to the outer side of the main body portion 313 and is arranged at an angle, and extends along the extending direction of the main body portion 313. The second flanging portion 319 is connected to the outer side of the connecting portion 315 and is arranged at an angle.

[0102] It can be understood that when the connecting body 31 is made of a metal material, specifically a sheet metal part for example, the first flanging portion 317 and the second flanging portion 319 can be formed by processes such as stamping, which is convenient for manufacturing and production.

[0103] On the basis of providing the first flanging portion 317, first of all, since the first flanging portion 317 and the main body portion 313 are arranged at an angle, the first flanging portion 317 can strengthen the strength of the main body portion 313, so as to increase the overall strength of the connecting main body 31. Secondly, since the first flanging portion 317 is connected to the outer side of the main body portion 313, the first flanging portion 317 can also play a limiting effect on the connecting main body 31. For example, it plays a limiting role on a plurality of fixed elastic portions 333, ensuring the stability of the connection between the fixed elastic portions 333 and the main body portion 313. Moreover, since the first flanging portion 317 extends along the extending direction of the main body portion 313, during the actual installation process of the fixed main body 33, the fixed elastic portions 333 can be guided by the first flanging portion 317 along the extending direction of the first flanging portion 317 to the installation position where they need to stay, so as to facilitate the staff to install the plurality of fixed elastic portions 333 of the fixed main body 33 on the main body portion 313 of the connecting main body 31. On the basis of providing the second flanging portion 319, first of all, since the second flanging portion 319 and the main body portion 313 are arranged at an angle, the second flanging portion 319 can cooperate with the first flanging portion 317 to jointly strengthen the strength of the main body portion 313, so as to greatly increase the overall strength of the connecting main body 31.

[0104] In some embodiments, the fixed main body 33 abuts against the support beam 10. In this way, the risk that the connecting pipeline 320 disengages from the gap between the fixed main body 33 and the support beam 10 can be avoided, and the abutting and fixing effect of the fixed groove 331 on the connecting pipeline 320 can be improved.

[0105] In some embodiments, the fixed main body 33 and the support beam 10 are arranged at intervals. In this way, during the process of the fixed main body 33 pressing towards the connecting pipeline 320, the possibility that the fixed main body 33 abuts against the support beam 10 and causes the fixed main body 33 to be unable to elastically deform well to press towards the connecting pipeline 320 can be reduced.

[0106] Please refer to Figures 7 to 8 , in some embodiments, the fixing assembly 100 further includes an anti-wear pad 50. The anti-wear pad 50 can be arranged in a strip shape and extend along the extending direction of the fixed main body 33. Moreover, the anti-wear pad 50 can be made of a material with excellent elastic properties such as rubber.

[0107] The anti-wear pad 50 is arranged on the surface of the support beam 10 facing the connecting pipeline 320, and the fixed main body 33 abuts against the anti-wear pad 50. In this way, through the arrangement of the anti-wear pad 50, it can be avoided that the connecting pipeline 320 is directly supported by the support beam 10, thereby avoiding the situation that the connecting pipeline 320 is damaged and generates noise due to friction with the support beam 10.
