Description

Technical Field

[0001] This application relates to the field of fabric duct technology, and in particular to a fabric duct with a reinforced shaping structure. Background Technology

[0002] Fabric ducts, as a type of flexible air delivery terminal device, offer advantages such as uniform air delivery, light weight, and ease of installation and storage. They are typically made of permeable fabric materials, delivering air through fiber gaps or specially designed openings.

[0003] Existing fabric ducts often use simple clamps for fastening when connected to rigid transmission ducts. While these methods are simple in structure, they are prone to loosening, poor sealing, or even detachment under long-term use or system pressure fluctuations, affecting the stable operation of the air supply system. More importantly, the fabric duct itself is soft and easily deformed, wrinkled, or even partially collapsed under the influence of internal airflow or slight external contact. This not only disrupts the duct's design but also leads to disordered airflow organization. For the built-in support structure, how to easily adjust and lock its support range while ensuring the stability of the support components within the duct is a major problem that urgently needs to be solved in existing technologies.

[0004] Therefore, a fabric duct with a reinforced shaping structure is proposed to solve the technical problem of the lack of built-in support structure in ducts. Utility Model Content

[0005] The purpose of this invention is to provide a fabric duct with a reinforced shaping structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fabric duct with a reinforced shaping structure, comprising a fabric duct, the cross-section of which is elliptical, and both ends of which are fixedly installed with snap-fit ​​components for connecting air inlets and outlets; one end of the fabric duct is connected to a transmission pipe via a snap-fit ​​component; a winding component is provided inside the fabric duct for winding up the built-in net; and two clamping components are also provided opposite to each other inside the fabric duct for clamping the built-in net.

[0007] According to the above technical solution, both ends of the fabric duct are fixedly installed with snap-fit ​​components. The snap-fit ​​components include zipper strips. One end of the zipper strips is fixedly installed at one end of the fabric duct, and the other end of the zipper strips is toothed.

[0008] The cross-section of the transmission tube is circular. A zipper strip is fixedly installed at one end of the transmission tube near the fabric duct. One end of the zipper strip is fixedly installed at one end of the transmission tube, and the other end of the zipper strip is toothed. The fabric duct and the zipper strip on the transmission tube are fixed together by interlocking zipper heads.

[0009] Several clips are fixedly installed on the outer wall of the transmission tube for tightening the transmission tube.

[0010] When assembling the fabric duct and the transmission duct, align the zipper strip at one end of the fabric duct with the zipper strip on the transmission duct, ensuring that the teeth of both interlock accurately. Then, slowly and evenly pull the zipper head, allowing the zipper strip to gradually engage along the connection point of the fabric duct and the transmission duct. When the zipper head reaches the end of the zipper strip, the two are tightly connected, indicating that the fabric duct and the transmission duct are successfully connected. Furthermore, the clips on the outer wall of the transmission duct can further tighten the transmission duct, thereby ensuring the stable operation of the air supply system.

[0011] According to the above technical solution, the winding assembly includes a cylindrical column, which is fixedly installed on the inner wall of one side of the fabric duct. Two cylindrical caps are fixedly installed at both ends of the cylindrical column, and the size of the caps matches the dimensions of the two ends of the cylindrical column. One of the caps is fixedly installed with a fixing box inside the cylindrical column. Two cylindrical caps are rotatably mounted on opposite ends with a rotating rod that passes through the bottom of the fixing box. A torsion spring is welded to the outer wall of the end of the rotating rod located inside the fixing box. An internal mesh is welded to the end of the torsion spring away from the rotating rod through a hole in the side wall of the fixing box. The internal mesh is used to support and maintain the shape of the fabric duct.

[0012] The cylindrical column has through holes corresponding to the positions of the inner mesh, allowing the inner mesh to extend out of the column. When it is necessary to pull out the inner mesh, pulling the inner mesh drives the rotating rod to rotate, and the rotation of the rotating rod causes the torsion spring to contract, giving the inner mesh a force to be rolled into the cylindrical column; when it is necessary to roll up the inner mesh, releasing the inner mesh causes the torsion spring to return to its original deformation, causing the rotating rod to rotate in the opposite direction, thereby rolling the inner mesh into the cylindrical column.

[0013] According to the above technical solution, a number of zipper teeth are fixedly installed on the side wall of the built-in mesh; two clamping components are also arranged opposite each other inside the fabric air duct, one of which is symmetrically placed with the winding component about the axis of the fabric air duct, and the other clamping component is fixedly installed on the inner wall of the fabric air duct near the winding component.

[0014] The clamping assembly includes a fixed pull bar, one end of which is fixedly installed on the inner wall of the fabric duct. The end of the fixed pull bar away from the fabric duct is toothed. Locking blocks are provided at the top and bottom of the fixed pull bar to prevent the pull head from slipping off. The fixed pull bar and the zipper teeth are engaged or disengaged by the pull head, thereby fixing the built-in mesh inside the fabric duct.

[0015] When it is necessary to clamp the inner mesh, slide the zipper head along the toothed end of the fixed zipper bar, so that the zipper teeth of the fixed zipper bar and the inner mesh at the end away from the cylinder column can engage with each other, thereby tightly connecting the inner mesh and the fixed zipper bar and fixing the inner mesh.

[0016] After the built-in mesh extends out of the cylinder, it works with the clamping assembly to support and maintain the shape of the fabric duct. The shape of the fabric duct can be limited by controlling the length of the built-in mesh. When the air velocity inside the fabric duct is low and the installation position is narrow, the extended part of the built-in mesh can be shortened, making the elliptical fabric duct have a larger eccentricity and a flatter shape, thus maximizing ventilation while saving space.

[0017] When the air velocity inside the fabric duct is high, the extended part of the inner mesh becomes longer, which makes the elliptical fabric duct have a smaller eccentricity, a more circular shape, and a more stable duct structure with better support.

[0018] When the air velocity inside the fabric duct is too high, more stable support is required. The zipper teeth on the middle section side wall of the inner mesh are engaged and fixed with the fixed pull strip away from the winding assembly, while the zipper teeth on the end of the inner mesh away from the cylinder are engaged with the fixed pull strip near the cylinder. At this time, two layers of inner mesh are formed inside the fabric duct, which enhances the support force and ensures the stability of the inner mesh when supporting the shape of the fabric duct, effectively improving the performance and reliability of the fabric duct.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0020] (1) The flexible winding and clamping of the built-in mesh is achieved through the cooperation of the winding assembly and the clamping assembly. The design of components such as the torsion spring and rotating rod in the winding assembly ensures that the built-in mesh remains stable during the pulling out and winding process, and is easy to operate. The clamping assembly fixes the built-in mesh, and adjusts the double-layer built-in mesh inside the fabric duct according to the installation environment, ensuring the stability and reliability of the built-in mesh in supporting the shape of the fabric duct. This design enables the built-in support structure of the fabric duct to provide stable support for the fabric duct. Attached Figure Description

Detailed Implementation

[0027] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-4 The present invention provides a technical solution: a fabric duct 1 with a reinforced shaping structure, comprising a fabric duct 1, the fabric duct 1 having an elliptical cross-section, and both ends of the fabric duct 1 being fixedly installed with snap-fit ​​components 2; one end of the fabric duct 1 is snap-fitted with a transmission pipe 3 by the snap-fit ​​components 2; the inside of the fabric duct 1 is provided with a winding component 4 for winding up an internal mesh 406; and the inside of the fabric duct 1 is also provided with two opposing clamping components 5 for clamping the internal mesh 406.

[0029] like Figure 1 As shown, both ends of the fabric duct 1 are fixedly installed with snap-fit ​​components 2. The snap-fit ​​components 2 include a zipper strip 201. One end of the zipper strip 201 is fixedly installed at one end of the fabric duct 1, and the other end of the zipper strip 201 is toothed.

[0030] The cross-section of the transmission pipe 3 is circular. A zipper strip 201 is fixedly installed at one end of the transmission pipe 3 near the fabric air duct 1. The zipper strip 201 on the fabric air duct 1 and the transmission pipe 3 are interlocked and fixed by the zipper head 202.

[0031] Several buckles 301 are fixedly installed on the outer wall of the transmission pipe 3 for tightening the transmission pipe 3.

[0032] When assembling the fabric duct 1 and the transmission pipe 3, align the zipper strip 201 at one end of the fabric duct 1 with the zipper strip 201 on the transmission pipe 3, ensuring that the toothed parts of both can accurately engage. Then, slowly and evenly pull the zipper head 202, causing the zipper strip 201 to gradually engage along the connection point of the fabric duct 1 and the transmission pipe 3. When the zipper head 202 is pulled to the end of the zipper strip 201, the two are tightly connected, and the fabric duct 1 and the transmission pipe 3 are successfully connected. In addition, the buckle 301 on the outer wall of the transmission pipe 3 can further tighten the transmission pipe 3, thereby ensuring the stable operation of the air supply system.

[0033] like Figure 2 and Figure 4 As shown, the winding assembly 4 includes a cylindrical column 402, which is fixedly installed on the inner wall of one side of the fabric duct 1. A cylindrical cover 401 is fixedly installed at both ends of the cylindrical column 402, the size of which matches the dimensions of both ends of the cylindrical column 402. One of the cylindrical covers 401 is fixedly installed with a fixing box 404. A rotating rod 403 is rotatably installed at one end of each of the two cylindrical covers 401. The rotating rod 403 passes through the bottom end of the fixing box 404. A torsion spring 405 is fixedly installed on the outer wall of one end of the rotating rod 403 near the fixing box 404. An internal mesh 406 is fixedly installed at the other end of the torsion spring 405 through a hole in the side wall of the fixing box 404. The internal mesh 406 is used to support and maintain the shape of the fabric duct 1.

[0034] The cylindrical column 402 has a through hole at the position corresponding to the inner mesh 406, so that the inner mesh 406 extends out of the cylindrical column 402.

[0035] When the built-in net 406 needs to be pulled out, pulling the built-in net 406 causes the rotating rod 403 to rotate. The rotation of the rotating rod 403 causes the torsion spring 405 to contract. The torsion spring 405 gives the built-in net 406 a force to roll it into the cylinder 402. When the built-in net 406 needs to be rolled up, the built-in net 406 is released. At this time, the torsion spring 405 will restore its deformation and cause the rotating rod 403 to rotate in the opposite direction, thereby rolling the built-in net 406 into the cylinder 402.

[0036] like Figure 3 and Figure 4 As shown, a plurality of zipper teeth 407 are fixedly installed on the side wall of the built-in mesh 406;

[0037] The fabric duct 1 is also provided with two clamping components 5 facing each other. One of the clamping components 5 is placed symmetrically with the winding component 4 about the axis of the fabric duct 1, and the other clamping component 5 is fixedly installed on the inner wall of the fabric duct 1 on the side close to the winding component 4.

[0038] The clamping assembly 5 includes a fixed pull bar 501. One end of the fixed pull bar 501 is fixedly installed on the inner wall of the fabric duct 1. The end of the fixed pull bar 501 away from the fabric duct 1 is toothed. Locking blocks are provided at the top and bottom of the fixed pull bar 501 to prevent the pull head 502 from slipping off. The fixed pull bar 501 and the zipper teeth 407 can be engaged or separated by the pull head 502, thereby fixing the built-in mesh 406 inside the fabric duct 1.

[0039] When it is necessary to clamp the inner mesh 406, slide the zipper head 502 along the toothed end of the fixed zipper bar 501, so that the zipper teeth 407 of the fixed zipper bar 501 and the inner mesh 406 away from the cylinder 402 can engage with each other, so that the inner mesh 406 is tightly connected to the fixed zipper bar 501, thereby fixing the inner mesh 406.

[0040] After the built-in net 406 extends out of the cylinder 402, it works with the clamping assembly 5 to support and maintain the shape of the fabric duct 1. The shape of the fabric duct 1 can be limited by controlling the length of the built-in net 406. When the air velocity inside the fabric duct 1 is low and the installation position is narrow, the extended part of the built-in net 406 can be shortened, making the elliptical fabric duct 1 have a larger eccentricity and a flatter shape, thus maximizing ventilation while saving space.

[0041] When the air velocity inside the fabric duct 1 is high, the extended part of the inner mesh 406 becomes longer, making the elliptical fabric duct 1 have a smaller eccentricity, making the shape more circular, the duct structure more stable, and the support better.

[0042] When the air velocity inside the fabric duct 1 is too high, more stable support is required. The zipper teeth 407 on the middle section side wall of the built-in mesh 406 are engaged and fixed with the fixed pull strip 501 away from the winding assembly 4. Meanwhile, the zipper teeth 407 at the end of the built-in mesh 406 away from the cylinder 402 are engaged with the fixed pull strip 501 at the end closer to the cylinder 402. At this time, two layers of built-in mesh 406 are formed inside the fabric duct 1, which enhances the support force and ensures the stability of the built-in mesh 406 in supporting the shape of the fabric duct 1, effectively improving the performance and reliability of the fabric duct 1.

[0043] The above three clamping schemes for the built-in mesh 406 can be selected to achieve stable fixation for different installation environments and wind speeds.

[0044] Working Principle: In actual use, when connecting the fabric duct 1 and the transmission pipe 3, align the zipper strip 201 at one end of the fabric duct 1 with the zipper strip 201 on the transmission pipe 3, ensuring that the teeth of both can accurately engage. Then, slowly and evenly pull the zipper head 202, causing the zipper strip 201 to gradually engage along the connection point of the fabric duct 1 and the transmission pipe 3. When the zipper head 202 reaches the end of the zipper strip 201, the two are tightly connected, and the fabric duct 1 and the transmission pipe 3 are successfully connected. Furthermore, the buckle 301 on the outer wall of the transmission pipe 3 can further tighten the transmission pipe 3, thereby ensuring the stable operation of the air supply system.

[0045] When the wind force changes in the environment where the fabric duct 1 is located, the internal winding component 4 and clamping component 5 work together. If the wind force increases, it is necessary to strengthen the support of the fabric duct 1. At this time, the operator can pull out more of the built-in net 406. As the extended part of the built-in net 406 becomes longer, the eccentricity of the elliptical fabric duct 1 decreases, and the shape becomes closer to a circle. The duct structure becomes more stable and can better withstand the pressure brought by strong winds. At the same time, one end of the built-in net 406 can be fixed to the second clamping component 5 and the middle section can be fixed to the first clamping component 5 as needed, forming a two-layer support structure of built-in net 406. This further increases the force supporting the shape of the fabric duct 1, ensuring that the duct maintains a stable shape and good ventilation performance even in strong winds.

[0046] If the wind force decreases and the installation location is narrow and space needs to be saved, the torsion spring 405 restores its deformation, causing the rotating rod 403 to rotate in the opposite direction, winding the inner net 406 into a portion of the cylinder 402, shortening the protruding part of the inner net 406. At this time, the elliptical fabric duct 1 has a larger eccentricity and a flatter shape, saving installation space while still providing ventilation. If it is necessary to adjust the position of the inner net 406 or remove it for maintenance, simply pull the pull head 502 to disengage the inner net 406 from the fixed pull bar 501, allowing for easy subsequent operations. This fabric duct 1 with a reinforced shaping structure, through the cooperation of the winding assembly 4, clamping assembly 5, and snap-fit ​​assembly 2, can flexibly adjust its shape and support structure according to different usage environments and needs, exhibiting high practicality and adaptability.
