[0030] The air conditioning and ventilation system connected to the fairing includes ventilation hoses, which are usually suspended in the air, resulting in no other bearing points for the ventilation hoses. Affected by the weight of the ventilation hoses, the upper section of the vertically installed ventilation hoses is subjected to greater force. During the debugging process, the ventilation hoses connected to the fairings are frequently opened and closed due to the moving mechanism, causing the fatigue life of the ventilation hoses to reach their limit prematurely. The non-pre-insulated section of the ventilation hoses is prone to tearing, resulting in more frequent replacement of new ventilation hoses, which seriously affects the project cost and the reliability of the air conditioning and ventilation system.

[0031] In order to solve the above technical problems, the present application designs a connector that can improve the strength of the connection of the ventilation hose, and the connector can form a bearing point, reducing the occurrence of local tearing of the upper end of the ventilation hose due to the opening and closing actions of the moving mechanism, thereby extending the service life of the ventilation hose and helping to reduce project costs.

[0032] Figure 1 FIG. 1 shows a schematic structural diagram of a connector 10 in an embodiment of the present application. Figure 2 and Figure 3 Schematic diagrams of the structures of the connector 10 and the ventilation hose 20 before and after being connected in one embodiment of the present application are respectively shown.

[0033] See also Figure 1-Figure 3 An embodiment of the present application provides a connector 10, which is used to connect a ventilation hose 20. The ventilation hose 20 includes an inner tube 21 and an outer tube 22 that is spaced apart and sleeved on the inner tube 21. The inner tube 21 is telescopically arranged in the outer tube 22 along the axial direction of the inner tube 21.

[0034] Specifically, the ventilation hose 20 further includes a heat-insulating layer 23, which is provided between the inner tube 21 and the outer tube 22. The heat-insulating layer 23 can be made of insulating cotton.

[0035] Optionally, both inner tube 21 and outer tube 22 include an inner layer, an outer layer, a high-temperature resistant layer disposed between the inner and outer layers, and multiple elastic steel wires. The multiple elastic steel wires are arranged at intervals along the axis of inner tube 21 and surround the inner layer. The inner and outer layers can be made of fiberglass wool, and the high-temperature resistant layer can be made of an insulating material, such as insulating fiber. The multiple elastic steel wires are wrapped between the inner and outer layers, and the outer layer is reinforced with white fiber yarn, providing a double-layer reinforcement effect.

[0036] The connector 10 includes a first connector 110, a second connector 120, a first fastener 200, and a second fastener 300. The first connector 110 and the second connector 120 are connected along the axis of the inner tube 21. Along the axis of the inner tube 21, the first connector 110 is inserted into the inner tube 21, and the second connector 120 is inserted into the outer tube 22 and is located on one side of the inner tube 21. The first fastener 200 is mounted on the inner tube 21 to restrict the movement of the first connector 110 relative to the inner tube 21. The second fastener 300 is mounted on the outer tube 22 to restrict the movement of the second connector 120 relative to the outer tube 22.

[0037] When the connector 10 of the present application is used, the inner tube 21 can be stretched along the axial direction of the inner tube 21, and one end of the inner tube 21 can be extended outside the outer tube 22, and the first joint 110 can be inserted into the inner tube 21, and then the first fastener 200 can be sleeved on the inner tube 21, and the movement of the first joint 110 relative to the inner tube 21 can be restricted by the first fastener 200; then the inner tube 21 can be stretched and contracted along the axial direction of the inner tube 21, so that the inner tube 21 is retracted into the outer tube 22, and the second joint 120 can be moved along with the inner tube 21. By inserting it into the outer tube 22 and then sleeved on the outer tube 22, the second fastener 300 can limit the movement of the second joint 120 relative to the outer tube 22. In this way, the inner tube 21 and the outer tube 22 of the ventilation hose 20 are both connected to the connector 10, which can enhance the connection strength of the connection of the ventilation hose 20, thereby reducing the risk of damage to the ventilation hose 20 during the opening and closing process of the moving mechanism, thereby extending the service life and service life of the ventilation hose 20, and also helping to reduce project costs.

[0038] In some embodiments, the first fastener 200 includes a first hoop 210 and a first locking member 220. The first hoop 210 is sleeved on the inner tube 21. The first locking member 220 is provided on the first hoop 210 and is used to adjust the size of the first hoop 210 along the radial direction of the inner tube 21.

[0039] Specifically, the first fastener 200 is a first throat clamp, and the first locking member 220 is a bolt.

[0040] In this way, the first hoop 210 can be sleeved on the inner tube 21, and the first locking piece 220 can be tightened, thereby reducing the radial size of the first hoop 210 along the inner tube 21, so that the first hoop 210 is tightly clamped on the outer wall of the inner tube 21, and the first joint 110 is more firmly connected to the inner tube 21, which can improve the connection strength of the connection of the ventilation hose 20.

[0041] In some embodiments, the second fastener 300 includes a second hoop 310 and a second locking member 320. The second hoop 310 is sleeved on the outer tube 22. The second locking member 320 is provided on the second hoop 310 and is used to adjust the size of the second hoop 310 along the radial direction of the inner tube 21.

[0042] Specifically, the second fastening member 300 is a second throat clamp, and the second locking member 320 is a bolt.

[0043] In this way, after the second joint 120 is inserted into the outer tube 22, the second hoop 310 can be sleeved on the outer tube 22 and the second locking piece 320 can be tightened, thereby reducing the radial size of the second hoop 310 along the inner tube 21, so that the second hoop 310 is tightly clamped on the outer wall of the outer tube 22, thereby making the second joint 120 more firmly connected to the outer tube 22, which can improve the connection strength of the connection of the ventilation hose 20.

[0044] In some embodiments, along the radial direction of the inner tube 21 , the size of the first joint 110 is D1, and the size of the second joint 120 is D2, wherein D2>D1, and D2-D1=D0, and D0 is equal to twice the distance between the inner tube 21 and the outer tube 22 along the radial direction of the inner tube 21.

[0045] The dimensions of the first joint 110 and the second joint 120 along the radial direction of the inner tube 21 can be designed according to the distance between the inner tube 21 and the outer tube 22 along the radial direction of the inner tube 21, so that the first joint 110 can be more fitly inserted into the inner tube 21 and the second joint 120 can be more fitly inserted into the outer tube 22.

[0046] A first sealing ring 400 is sleeved on the first joint 110 , and the first sealing ring 400 is disposed between the first joint 110 and the inner tube 21 .

[0047] Specifically, the first sealing ring 400 is an F-type rubber ring.

[0048] In this way, the gap between the first joint 110 and the inner tube 21 can be sealed by the first sealing ring 400, thereby improving the sealing of the connection of the ventilation hose 20, which is beneficial to reduce the impact of the connector 10 on the air supply temperature of the air conditioner, and also improve the thermal insulation performance of the ventilation hose 20.

[0049] In some embodiments, the first sealing ring 400 is disposed in a gap between the first joint 110 and the inner tube 21 in an interference fit manner.

[0050] Specifically, the radial dimension of the first sealing ring 400 is slightly larger than the inner diameter of the inner tube 21 .

[0051] In this way, the sealing performance of the connection of the ventilation hose 20 can be improved, thereby helping to reduce the impact of the connector 10 on the air temperature of the air conditioner, and also improving the thermal insulation performance of the ventilation hose 20.

[0052] In some embodiments, a reinforcing rib 121 is provided on the outer peripheral wall of the second joint 120 . The reinforcing rib 121 is located on one side of the second fastener 300 along the axial direction of the inner tube 21 to limit the movement of the second fastener 300 along the axial direction of the inner tube 21 .

[0053] In this way, on the one hand, the reinforcing rib 121 can be used to increase the strength of the second joint 120, thereby improving the connection reliability of the connector 10; on the other hand, the reinforcing rib 121 can be used to limit the movement of the second fastener 300 along the axial direction of the inner tube 21, thereby improving the connection reliability of the connection between the second joint 120 and the ventilation hose 20.

[0054] In some embodiments, along the axial direction of the inner tube 21 , one end of the second joint 120 has a first edge portion 122 , and along the axial direction of the inner tube 21 , there is a preset distance between the reinforcing rib 121 and the first edge portion 122 of the second joint 120 .

[0055] The preset spacing may be 4 mm to 6 mm. For example, the preset spacing is 4 mm, 5 mm or 6 mm.

[0056] Since there is a preset distance between the reinforcing rib 121 and the first edge portion 122 of the second joint 120 along the axial direction of the inner tube 21, the reinforcing rib 121 can be used to improve the strength of the first edge portion 122, thereby improving the reliability of the second joint 120 and the connector 10.

[0057] In some embodiments, the connector 10 further includes a third joint 130 , wherein a portion of the third joint 130 is disposed within the second joint 120 along the axial direction of the inner tube 21 , and another portion of the third joint 130 protrudes from the second joint 120 for connecting to the rigid tube 30 .

[0058] Specifically, along the axial direction of the inner tube 21 , one end of the third joint 130 is connected to the first joint 110 , and the other end of the third joint 130 protrudes out of the second joint 120 .

[0059] In this way, the first joint 110 of the connector 10 can be connected to the inner tube 21 through the first fastener 200, and the second joint 120 of the connector 10 can be connected to the outer tube 22 through the second fastener 300, so that the first joint 110 and the second joint 120 of the connector 10 are respectively connected to the ventilation hose 20. In addition, the third joint 130 of the connector 10 can also be connected to the hard tube 30. Specifically, the third joint 130 is inserted into the hard tube 30 and the third joint 130 is fixed to the hard tube 30 by rivets (such as brushed rivets). In this way, the connector 10 can be used to connect the ventilation hose 20 and the hard tube 30.

[0060] In some embodiments, a second sealing ring 500 is provided on the third joint 130 , and the second sealing ring 500 is provided between the third joint 130 and the hard pipe 30 .

[0061] In this way, the gap between the third joint 130 and the hard tube 30 can be sealed by the second sealing ring 500, thereby improving the sealing of the connection between the connector 10 and the hard tube 30, which is beneficial to reduce the impact of the connector 10 on the air supply temperature of the air conditioner, and also improve the thermal insulation performance of the ventilation hose 20.

[0062] In some embodiments, the second sealing ring 500 is disposed in a gap between the third joint 130 and the hard tube 30 in an interference fit manner.

[0063] Specifically, the radial dimension of the second sealing ring 500 is slightly larger than the inner diameter of the hard tube 30 .

[0064] Specifically, the second sealing ring 500 is an F-type rubber ring.

[0065] In this way, the sealing performance of the connection between the connector 10 and the hard tube 30 can be improved, thereby helping to reduce the impact of the connector 10 on the air temperature of the air conditioner, and also improving the thermal insulation performance of the ventilation hose 20.

[0066] When the connector 10 of the present application is used, the first joint 110 can be inserted into the inner tube 21, and the first joint 110 can be fixed to the inner tube 21 by the first fastener 200 (i.e., the first throat clamp). Since the first sealing ring 400 is provided between the first joint 110 and the inner tube 21, the gap between the first joint 110 and the inner tube 21 can be squeezed and sealed by the first fastener 200 and the first sealing ring 400; the second joint 120 can also be inserted into the outer tube 22, and the second fastener 300 (i.e., the second throat clamp) can be used to fix the second joint 120 to the outer tube 22, thus completing the connection between the connector 10 and the ventilation hose 20; then the third joint 130 of the connector 10 is inserted into the hard tube 30, and the hard tube 30 is fixed with rivets around it, and the gap between the third joint 130 and the hard tube 30 is sealed by the second sealing ring 500, so that the connection between the connector 10 and the hard tube 30 can be achieved (can be combined Figure 4and Figure 5 In this way, the connection strength of the connection of the ventilation hose 20 can be enhanced, thereby reducing the risk of damage to the ventilation hose 20 during the opening and closing process of the movement mechanism, thereby extending the service life and service life of the ventilation hose 20, and also helping to reduce project costs.
