Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, and particularly relates to a flexible air duct pressure-resistant support device. Background Art

[0002] With the popularization of flexible composite materials, their application in air-conditioning ventilation ducts has also been continuously developed.

In this device, the first pipe section does not need to distinguish between the male chain end and the female chain end during production and installation, and can be connected to adjacent flexible air duct segments. It can not only solve the connection problem in the production and installation process of flexible air duct system components, but also avoid the situation where docking cannot be achieved due to temporary adjustment of the pipe section. Usually, under the action of the internal pressure of the air duct, the inner wall of the air duct with a circular cross-section bears the pressure basically evenly.

When the internal pressure of the pipe is too high, the joint of the pipe is prone to tearing and damage, resulting in high maintenance costs.

[0004] Therefore, there is an urgent need for a flexible air duct pressure-resistant support device to solve the problem in the prior art that due to excessive internal pressure of the pipe, the connection strength at the joint of the flexible air duct is poor and prone to tearing and damage, resulting in high maintenance costs.

[0037] It should be noted that the flexible air duct pressure-resistant support device of the present utility model is used in but not limited to the air duct technical field, etc. For the convenience of description, in the present utility model, only the case where the flexible air duct pressure-resistant support device is applied to the air duct technical field is taken as an example for description, and the principle of the flexible air duct pressure-resistant support device applied to other types of equipment is substantially the same as that applied to the air duct technical field, and will not be elaborated one by one here.

[0038] Please refer to Figures 1 to 3 , Figure 1 , Figure 2 is a schematic structural diagram of a flexible air duct pressure-resistant support device in an embodiment of the present utility model. The flexible air duct pressure-resistant support device is arranged between two air ducts 1. The opposite sides of the two air ducts 1 are respectively provided with a first male chain 11 or a first female chain 12, and includes: a support assembly 2 and two connecting parts 3. The support assembly 2 includes a support part 21. The support part 21 is arranged between the two air ducts 1, and the inside of the support part 21 is hollow and forms a ventilation channel communicating with the inside of the two air ducts 1. The two connecting parts 3 are respectively arranged on both sides of the support part 21 and are both connected to the support part 21. One connecting part 3 is detachably connected to the first male chain 11 or the first female chain 12 of one air duct 1, and the other connecting part 3 is detachably connected to the first male chain 11 or the first female chain 12 of the other air duct 1.

[0039] In this device, the support part 21 is arranged between two air ducts 1. The interior of the support part 21 is hollow and is formed with a ventilation passage communicating with the interiors of the two air ducts 1. The two connecting parts 3 are respectively arranged on both sides of the support part 21 and are respectively connected to the support part 21. One connecting part 3 can be detachably connected to the first male chain 11 or the first female chain 12 of one air duct 1, and the other connecting part 3 can be detachably connected to the first male chain 11 or the first female chain 12 of the other air duct 1.

[0040] Compared with the prior art, by arranging the support part 21 at the joint of the air duct 1, the support part 21 forms a detachable connection with the two air ducts 1 respectively through the two connecting parts 3. It can not only support the joint of the air duct 1, avoiding the tearing and damage at the joint due to the poor connection strength at the joint of the pipes when the pressure in the pipe is too high, but also can conveniently connect the support part 21 with the two air ducts 1, facilitating the pipe connection operation, being convenient for production and installation, and can solve the problem in the prior art that the connection strength at the joint of the flexible air duct connection is poor and is prone to tearing and damage due to the too high pressure in the pipe, resulting in high maintenance costs.

[0041] Specifically, the two ends of the air duct 1 are respectively provided with a first male chain 11 and a first female chain 12, and the adjacent two air ducts 1 are connected by matching the first male chain 11 and the first female chain 12. This belongs to the conventional setting well-known to those skilled in the art and will not be elaborated here too much.

[0042] In this embodiment, as Figure 1 、 Figure 2 shown, the cross-section of the support part 21 is circular or oval.

[0043] In this device, the cross-section of the support part 21 is circular or oval, which can be applicable to the air duct 1 with a circular or oval cross-section.

[0044] In this embodiment, the material strength of the support part 21 is greater than or equal to the material strength of the air duct 1.

[0045] Specifically, in the air duct 1 with a circular cross-section, the pressure borne by the inner wall of the air duct 1 is basically uniform, and the material strength of the support part 21 is equal to the material strength of the air duct 1.

[0046] Furthermore, in the oval air duct 1 with a circular cross-section, the pressure borne by the inner wall of the air duct 1 is inconsistent, and the material strength of the support part 21 is greater than the material strength of the air duct 1, playing a role in stable support.

[0047] In one of the embodiments, please refer to Figure 2, the cross-section of the support portion 21 is oblate, and the support assembly 2 further includes at least one first tension rib 22. The first tension rib 22 spans across the ventilation channel, and both ends of the first tension rib 22 are respectively connected to the circumferential inner walls opposite to each other of the ventilation channel.

[0048] By providing the first tension rib 22 that spans across the ventilation channel, the stability of the support portion 21 can be improved, and it can be applied to the oblate air duct 1 with a circular cross-section.

[0049] In one embodiment, please refer to Figure 2 , the support portion 21 has two straight ends and two arc ends. The two straight ends are arranged in parallel, and the two arc ends are respectively arranged at both ends of the two straight ends, and both ends of the two arc ends are respectively connected to both ends of the two straight ends. The number of the first tension ribs 22 in the support assembly 2 is two, and the two first tension ribs 22 are respectively connected to the joints of the straight ends and the arc ends.

[0050] Specifically, the joints of the straight ends and the arc ends will become weak points for bearing pressure. Therefore, the number of the first tension ribs 22 in the support assembly 2 is two.

[0051] In one embodiment, please refer to Figure 2 , the width of the first tension rib 22 is equal to the width of the support portion 21.

[0052] By providing the support portion 21 and the first tension rib 22 with equal widths, the supporting force provided by the support assembly 2 can be enhanced, and the supporting effect can be improved.

[0053] In one embodiment, the cross-section of the support portion 21 gradually increases or decreases in the direction close to the other air duct 1, and the cross-section of the first tension rib 22 is arranged to match the shape of the support portion 21.

[0054] By providing a structure with a gradually changing cross-section, the device can be applied to the connection and support between the variable-diameter air ducts 1, and the application range of the device can be improved.

[0055] In this embodiment, as Figure 3 shown, the air duct 1 includes an air duct cylinder 13 and at least one second tension rib 14. The second tension rib 14 spans across the air duct cylinder 13, and both ends of the second tension rib 14 are respectively connected to the circumferential inner walls opposite to each other of the air duct cylinder 13. The number of the second tension ribs 14 is equal to the number of the first tension ribs 22, and the length of the second tension rib 14 is greater than or equal to the length of the first tension rib 22.

[0056] The number and position of the first tension ribs 22 are consistent with the number and position of the second tension ribs 14 provided on the air duct 1, and it is satisfied that the length of the second tension rib 14 is greater than or equal to the length of the first tension rib 22, so as to better protect the second tension rib 14 in the air duct 1 from being torn or broken.

[0057] Further, in this device, the height of the support device can be adjusted by adjusting the height of the first tension bar 22 to better fit the oval air duct 1.

[0058] In this embodiment, as Figure 3 shown, the connecting part 3 includes a second male chain 31 or a second female chain 32 and a zipper buckle 33. The second male chain 31 of the connecting part 3 meshes with the first female chain 12 of one air duct, and the second female chain 32 of the connecting part 3 meshes with the first male chain 11 of the other air duct, and the zipper buckle 33 cooperates with and links the first male chain 11 and the second female chain 32 or the first female chain 12 and the second male chain 31.

[0059] By setting the connecting part 3 as a zipper structure adapted to the first male chain 11 and the first female chain 12 on the air duct 1, it is convenient for production and installation. The male chain, the female chain, and the zipper buckle 33 are all common and easily purchasable devices in the market. This belongs to the conventional settings well-known to those skilled in the art and will not be elaborated here too much.

[0060] Further, here the connecting part 3 can also be replaced by a connecting flange or a welding or splicing structure composed of two parts. The connecting flange or the welding and splicing structure here belongs to the conventional settings well-known to those skilled in the art and will not be elaborated here too much.

[0061] For a better understanding of the present utility model, the following combines Figures 1 to 3 to elaborate in detail on the technical solution of the present utility model:

[0062] The support part 21 is arranged between two air ducts 1, and the inside of the support part 21 is hollow and forms a ventilation channel communicating with the inside of the two air ducts 1. Two connecting parts 3 are respectively arranged on both sides of the support part 21 and are respectively connected to the support part 21. One connecting part 3 can be detachably connected to the first male chain 11 or the first female chain 12 of one air duct, and the other connecting part 3 can be detachably connected to the first male chain 11 or the first female chain 12 of the other air duct. Compared with the prior art, by arranging the support part 21 at the joint of the air duct 1, the support part 21 forms a detachable connection with the two air ducts 1 respectively through the two connecting parts 3. It can not only support the joint of the air duct 1 to avoid the tearing and damage at the joint when the internal pressure of the pipe is too large due to the poor connection strength at the pipe joint, but also can conveniently connect the support part 21 with the two air ducts 1, facilitating the pipe joint operation and being convenient for production and installation.

[0063] The specific working process of the present utility model is as follows: First, select the reinforcement position: Select a flexible air duct system with greater pressure, or select the air outlet of the fan equipment, or select to set a pressure-resistant support device at the reduced-diameter connection of the air duct 1, where the risk of tearing and damage to the air duct 1 is relatively high; Then, select the pressure-resistant support device: Select a circular air duct 1 or an oval air duct 1 according to the cross-section of different air ducts 1. The shape and size of the support portion 21 need to match the air ducts 1 on both sides. If an oval air duct 1 is selected, it is necessary to ensure that the height of the first tension rib 22 is less than or equal to the height of the second tension rib 14; Finally, install the pressure-resistant support device: Connect the first male chain 11 of the support portion 21 to the second female chain 32 of an air duct 1, and the zipper buckle 33 is connected to both the first male chain 11 of the support portion 21 and the second female chain 32 of an air duct 1. Connect the first female chain 12 of the support portion 21 to the second male chain 31 of the other air duct 1, and the zipper buckle 33 is connected to both the first female chain 12 of the support portion 21 and the second male chain 31 of the other air duct 1.

[0064] Furthermore, through the above support structure and its construction method, effective reinforcement can be achieved, preventing the flexible air duct from being torn or damaged under pressure, and at the same time reducing maintenance and production costs.

[0065] Through the above structure and method, the present utility model can solve the problem in the prior art that due to excessive pressure inside the pipe, the connection strength at the connection of the flexible air duct is poor and it is prone to tearing and damage, resulting in high maintenance costs.

[0066] The above specific implementation manners of the present utility model do not constitute a limitation to the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
