Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0036] The air conditioning system connected to the fairing includes air conditioning ducts. These ducts are usually suspended in the air, resulting in no other load-bearing points. Due to the weight of the ducts themselves, the upper section of the ventilation hoses in vertically installed air conditioning ducts is subjected to greater stress, making them prone to tearing and other problems during commissioning, which in turn affects the reliability of the air conditioning system.

[0037] To address the aforementioned technical problems, this application presents a fixing device for air conditioning pipes, which can limit and fix the air conditioning pipes to the fixing device, thereby improving the stability and reliability of the air conditioning pipes and extending their service life.

[0038] Figure 1 A schematic diagram of the structure of an air conditioning pipe and fixing device according to an embodiment of this application is shown. Figure 2 A schematic diagram of the fixing device according to an embodiment of this application is shown. Figure 3 A bottom view of a fixing device according to an embodiment of this application is shown.

[0039] Please see Figures 1-3One embodiment of this application provides a fixing device 10 for an air conditioning duct 20. The air conditioning duct 20 includes a connected ventilation hose 21 and a connecting rigid pipe 22. The fixing device 10 includes two limiting mechanisms 100 and a positioner 200. The two limiting mechanisms 100 are arranged opposite to each other and spaced apart along a first direction F1. The positioner 200 is connected between the two limiting mechanisms 100 and has a fixing channel T for passing through the connecting rigid pipe 22 and extending along a second direction F2. The positioner 200 is used to restrict the movement of the connecting rigid pipe 22 along the radial direction of the fixing channel T.

[0040] In this way, the air conditioning pipe 20 can be installed through the fixed channel T, and the positioner 200 can be used to restrict the movement of the connecting rigid pipe 22 in the radial direction along the fixed channel T.

[0041] Each limiting mechanism 100 includes a cable chain body 110 and a mounting base 120. The mounting base 120 is disposed on the cable chain body 110. Optionally, the mounting base 120 is disposed at at least one end of the cable chain body 110 along the longitudinal extension direction of the cable chain body 110. Alternatively, the mounting base 120 may be disposed at one end of the cable chain body 110 along the longitudinal extension direction of the cable chain body 110, or it may be disposed at opposite ends of the cable chain body 110 along the longitudinal extension direction of the cable chain body 110.

[0042] When using the fixing device 10 of this application, the fixing device 10 can be fixed to one side of the air conditioning pipe 20 through the mounting base 120, and the air conditioning pipe 20 is limited between the drag chain bodies 110 of the two limiting mechanisms 100. The connecting rigid pipe 22 of the air conditioning pipe 20 is set through the fixed channel T. Then, the positioner 200 is used to limit the movement of the connecting rigid pipe 22 in the radial direction along the fixed channel T. In this way, the air conditioning pipe 20 can be limited and fixed on the fixing device 10, so that the weight of the air conditioning pipe 20 can be transferred to the drag chain body 110. This can reduce the occurrence of local tearing of the air conditioning pipe 20 due to the opening and closing action of the moving mechanism, thereby extending the service life of the air conditioning pipe 20 and also helping to reduce project costs.

[0043] In some embodiments, please refer to Figure 2 and Figure 4 The cable chain body 110 includes at least two chain plates, each of which includes a plurality of first chain plates 111 and a plurality of second chain plates 112 arranged end to end and alternately. One of the first chain plates 111 and the adjacent second chain plates 112 is rotatable about an axis parallel to the first direction F1 relative to the other of the first chain plates 111 and the adjacent second chain plates 112.

[0044] Alternatively, the first chain plate 111 can rotate relative to the adjacent second chain plate 112 about an axis parallel to the first direction F1; or the second chain plate 112 can rotate relative to the adjacent first chain plate 111 about an axis parallel to the first direction F1.

[0045] In this way, while the air conditioning pipe 20 is confined between the cable chain bodies 110 of the two limiting mechanisms 100, the first chain plate 111 can rotate relative to the adjacent second chain plate 112 about an axis parallel to the first direction F1, or the second chain plate 112 can rotate relative to the adjacent first chain plate 111 about an axis parallel to the first direction F1. This allows the cable chain body 110 to be shaped to follow the extension direction of the air conditioning pipe 20 (for example, the cable chain body 110 can be arranged as follows). Figure 2 and Figure 4 The bending setting shown in the figure helps to limit the air conditioning pipe 20 while also giving the air conditioning pipe 20 a certain degree of freedom in bending deformation, thereby reducing the occurrence of local tearing on the air conditioning pipe 20 and extending the service life of the air conditioning pipe 20.

[0046] In some embodiments, the first chain plate 111 and the second chain plate 112 are respectively provided with at least two pin holes K spaced apart and extending along the first direction F1. The number of first chain plates 111 is even. Two first chain plates 111 spaced apart along the first direction F1 are defined as a group of first chain plates. The first chain plate groups and the second chain plates 112 are arranged alternately, and one end of the second chain plate 112 is located between the two first chain plates 111 of the adjacent first chain plate group. The cable chain body 110 also includes a pin 113 adapted to the pin holes K. The pin 113 is inserted into the pin holes K on the two first chain plates 111 of the first chain plate group and the adjacent second chain plate 112 to connect the first chain plate group and the adjacent second chain plate 112.

[0047] Optionally, the pin 113 is constructed as a solid structure.

[0048] Thus, the second chain plate 112 can rotate relative to the adjacent first chain plate group around an axis parallel to the first direction F1. Since one end of the second chain plate 112 is located between the two first chain plates 111 of the adjacent first chain plate group, the reliability and stability of the rotation of the second chain plate 112 can be improved. This is beneficial for limiting the air conditioning pipe 20, while also giving the air conditioning pipe 20 a certain degree of freedom for bending deformation. This can reduce the occurrence of local tearing on the air conditioning pipe 20 caused by the opening and closing action of the moving mechanism, thereby extending the service life of the air conditioning pipe 20.

[0049] In some embodiments, the first chain plate 111 and the second chain plate 112 are respectively provided with a plurality of pin holes K extending along the first direction F1. The plurality of pin holes K on the same chain plate are arranged to form two sets of pin hole groups with intervals. Each set of pin holes includes a first pin hole K1 and two second pin holes K2 with intervals, and the first pin hole K1 is located between the two second pin holes K2. The drag chain body 110 also includes a pin shaft 113 adapted to the pin hole K. The pin shaft 113 is inserted into two adjacent first pin holes K1 in the first chain plate 111 and the adjacent second chain plate 112 to connect the first chain plate 111 and the adjacent second chain plate 112.

[0050] This facilitates the rotation of the first chain plate 111 relative to the adjacent second chain plate 112 about an axis parallel to the first direction F1, and also facilitates the rotation of the second chain plate 112 relative to the adjacent first chain plate 111 about an axis parallel to the first direction F1.

[0051] In some embodiments, the locator 200 includes an open ring 210 disposed on the cable chain body 110 and a first connector 220. The open ring 210 defines a fixed channel T, and the two opposite ends of the open ring 210 along its arc length direction define an opening U communicating with the fixed channel T. The two opposite ends of the open ring 210 along its arc length direction are detachably connected by the first connector 220.

[0052] Thus, the connecting rigid tube 22 can be inserted into the fixed channel T through the opening U, and the two ends of the opening ring 210 along the arc length direction of the opening ring 210 can be connected through the first connector 220, thereby confining the connecting rigid tube 22 within the fixed channel T and restricting the movement of the connecting rigid tube 22 along the radial direction of the fixed channel T.

[0053] In some embodiments, the first connector 220 further includes a bolt 221 and a fastener 222. The open ring 210 has a first through hole (not shown) and a second through hole (not shown) at opposite ends along the arc length direction of the open ring 210. The bolt 221 passes through the first through hole and the second through hole and is threaded to the fastener 222.

[0054] Thus, the connecting rigid tube 22 can be inserted into the fixed channel T through the opening U, and the bolt 221 can be inserted through the first through hole and the second through hole and threaded onto the fastener 222. Then the fastener 222 is tightened to connect the two ends of the opening ring 210 along the arc length direction of the opening ring 210. This can confine the connecting rigid tube 22 within the fixed channel T, thereby restricting the movement of the connecting rigid tube 22 in the radial direction of the fixed channel T.

[0055] In some embodiments, the fixing device 10 includes two positioners 200, which are respectively disposed at opposite ends of the cable chain body 110 along the longitudinal extension direction of the cable chain body 110.

[0056] One of the positioners 200 can restrict the movement of one end of the air conditioning pipe 20 in the radial direction along the corresponding fixed channel T, and the other positioner 200 can restrict the movement of the other end of the air conditioning pipe 20 in the radial direction along the corresponding fixed channel T. In this way, the stability of the air conditioning pipe 20 can be improved, and the occurrence of local tearing of the air conditioning pipe 20 caused by the opening and closing action of the moving mechanism can be better reduced. This can extend the service life of the air conditioning pipe 20 and also help reduce project costs.

[0057] In some embodiments, the fixing device 10 further includes at least one limiting member 300, which is connected between the drag chain bodies 110 of the two limiting mechanisms 100 to limit the air conditioning pipe 20 to one side along the radial direction of the air conditioning pipe 20.

[0058] Specifically, the limiting component 300 is constructed as a limiting baffle.

[0059] The limiting member 300 can be used to restrict the radial movement of the air conditioning pipe 20. The limiting member 300 and the drag chain body 110 of the two limiting mechanisms 100 enclose a semi-enclosed space, which can effectively reduce the impact of the rocket tail flame and the high-speed airflow ejected during rocket launch on the air conditioning pipe 20, thereby extending the service life of the air conditioning pipe 20.

[0060] Optionally, the limiting member 300 includes a plurality of limiting plates arranged along the longitudinal extension direction of the drag chain body 110. The limiting plates correspond one-to-one with the chain plates, and the limiting plates are located on the corresponding chain plates. The gap between two adjacent limiting plates is less than a preset value.

[0061] In this way, multiple limiting plates roughly form a "continuous" limiting part, which is placed on the inner circumference of the air conditioning pipe 20, so that the limiting member 300 can better form a semi-enclosed space with the drag chain body 110 of the two limiting mechanisms 100, which can effectively reduce the impact of the rocket tail flame and the high-speed airflow ejected during rocket launch on the air conditioning pipe 20, thereby extending the service life of the air conditioning pipe 20.

[0062] In some embodiments, the fixing device 10 further includes a plurality of limiting members 300, which are arranged on opposite sides of the drag chain body 110 along the third direction F3, and the first direction F1, the second direction F2 and the third direction F3 intersect each other.

[0063] Specifically, the third direction F3 is parallel to the width direction of the chain plate.

[0064] Thus, the multiple limiting components 300 are located on opposite sides of the air conditioning pipe 20 along the radial direction of the air conditioning pipe 20, which can improve the stability and reliability of the air conditioning pipe 20.

[0065] In this embodiment, multiple limiting members 300 located on the same side of the drag chain body 110 along the third direction F3 are arranged at intervals along the longitudinal extension direction of the drag chain body 110.

[0066] Multiple limiting members 300 located on the same side of the drag chain body 110 along the third direction F3 can be blocked on the inner circumference of the air conditioning pipe 20, so that the limiting members 300 can better form a semi-enclosed space with the drag chain body 110 of the two limiting mechanisms 100, which can effectively reduce the impact of the rocket tail flame and the high-speed airflow ejected during rocket launch on the air conditioning pipe 20, thereby extending the service life of the air conditioning pipe 20.

[0067] In some embodiments, please refer to Figure 3 The mounting base 120 has a through mounting hole 121, which is constructed as a waist hole.

[0068] Because the mounting hole 121 is constructed as a slotted hole, the position of the mounting base 120 can be adjusted according to actual installation requirements, thereby improving the installation flexibility of the mounting base 120. The fixing device 10 may also include a second connector 400 adapted to the mounting hole 121 (e.g., Figure 5 As shown), the second connector 400 may include bolts and nuts, and the fixing device 10 can be fixed to the mounting bracket 30 of the air conditioning pipe 20 through the second connector 400.

[0069] The fixing device 10 of this application is used to fix the air conditioning pipe 20, so that the weight of the air conditioning pipe 20 can be transferred to the cable chain body 110, which is beneficial to extend the service life of the air conditioning pipe 20. At the same time, the characteristics of the cable chain body 110 can be used to make the air conditioning pipe 20 bend inward or outward, which can take into account both the fixing strength and the flexible setting of the air conditioning pipe 20.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
