Description

Technical Field

[0001] This utility model relates to the field of composite duct technology, specifically a double-sided color steel composite duct for ventilation systems. Background Technology

[0002] Color steel composite air duct is an upgraded product of traditional fiberglass air duct and a new generation of galvanized iron sheet air duct. Its advantages include good air tightness, high strength, strong resistance to acid and alkali, rust prevention, good sound absorption and good heat insulation, eliminating the need for secondary insulation. Composite air ducts are often used in ventilation and air conditioning systems to transmit air during the installation of air conditioning systems.

[0003] In the existing technology, after the color steel plate composite air duct is assembled, it is usually necessary to install internal support components to ensure that the air duct will not deform. However, the current support components usually require drilling holes in the side wall of the air duct before installation, which is a cumbersome installation process and is prone to air leakage, affecting the normal use of the air duct. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a double-sided color steel composite air duct for a ventilation system, including an outer duct, wherein a quick support mechanism is provided on the inner side of the outer duct.

[0006] The quick support mechanism includes a mounting frame, a bidirectional screw is rotatably connected to the inner center of the mounting frame, a gripping ring is fixedly connected to the outer center of the bidirectional screw, threaded plates are threadedly connected to both the front and rear sides of the outer periphery of the bidirectional screw, and support blocks are fixedly connected to both the left and right ends of the side wall away from the gripping ring of the threaded plate. The support blocks are all slidably connected to the inside of the openings, which are respectively located on the left and right sides of the front and rear walls of the mounting frame.

[0007] As a preferred embodiment of this utility model, an inner tube is provided inside the outer tube, and a filling layer is fixedly connected between the inner tube and the outer tube.

[0008] As a preferred embodiment of this utility model, the openings are all fitted with the support blocks with a clearance, and the mounting frame is located inside the inner tube.

[0009] As a preferred technical solution of this utility model, the upper and lower ends of the outer tube, the filling layer and the inner tube are all slidably connected to the inner side of the connecting groove, and the connecting groove is set in the middle of the side wall of the connecting frame near the outer tube.

[0010] As a preferred embodiment of this utility model, the width of the connecting groove is greater than the sum of the widths of the outer tube, the filling layer, and the inner tube.

[0011] As a preferred technical solution of this utility model, the connecting frames are all fixedly connected to the inner side of the slots, and the slots are all located in the middle of the side wall of the connecting flange near the outer pipe.

[0012] As a preferred embodiment of this utility model, the connecting flange and the connecting frame are symmetrically arranged about the middle of the outer tube, and the slots are all clearance-fitted with the connecting frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. The double-sided color steel composite air duct used in this ventilation system, after the composite pipe is assembled, the installation frame is placed inside the inner pipe and the grip ring is rotated. During the rotation of the grip ring, the bidirectional screw rotates. The rotation of the bidirectional screw causes the threaded plates on the front and rear sides to move away from each other, thereby causing the support block fixed to the threaded plate to move outward. During the sliding process of the support block inside the opening, it contacts and squeezes the inner wall of the inner pipe, thereby supporting the inner wall of the composite air duct. This eliminates the need for drilling and reduces the difficulty of supporting the composite air duct.

[0015] 2. The double-sided color steel composite duct used in this ventilation system improves the sealing performance of the composite duct by changing the traditional support method of drilling holes, inserting support rods, and fixing them with nuts. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figures 1-5 As shown, the present invention discloses a double-sided color steel composite air duct for a ventilation system, including an outer pipe 1, and a quick support mechanism 2 is provided on the inner side of the outer pipe 1.

[0025] The quick-support mechanism 2 includes a mounting frame 9, which provides space for the quick-support mechanism 2 to be installed. A bidirectional screw 10 is rotatably connected to the center of the inner side of the mounting frame 9. During the rotation of the bidirectional screw 10 inside the mounting frame 9, the threaded plates 12 on the front and rear sides can move closer or further apart. A gripping ring 11 is fixedly connected to the center of the outer periphery of the bidirectional screw 10. The gripping ring 11 can reduce the difficulty of rotating the bidirectional screw 10. Threaded plates 12 are threadedly connected to the front and rear sides of the outer periphery of the bidirectional screw 10. Support blocks 13 are fixedly connected to the left and right ends of the side wall away from the gripping ring 11 on the side wall. During the outward movement of the four sets of support blocks 13 inside the opening 14, they can squeeze the inner wall of the inner tube 3, thereby supporting and fixing the inner tube 3. The support blocks 13 all penetrate and slide inside the opening 14. The opening 14 is respectively set on the left and right sides of the front and rear walls of the mounting frame 9.

[0026] An inner pipe 3 is provided inside the outer pipe 1. A filling layer 4 is fixedly connected between the inner pipe 3 and the outer pipe 1. The openings 14 are all fitted with the support block 13 with a clearance. The mounting frame 9 is set inside the inner pipe 3. The filling layer 4 is the internal insulation material of the double-sided color steel composite air duct, which is existing technology and therefore will not be described in detail.

[0027] The outer tube 1, the filling layer 4, and the inner tube 3 are all slidably connected to the inner side of the connecting groove 7 at both ends. The connecting groove 7 is set in the middle of the side wall of the connecting frame 5 near the outer tube 1. Both the outer tube 1 and the inner tube 3 are made of color steel plate, hence the name double-sided color steel composite air duct.

[0028] The width of the connecting groove 7 is greater than the sum of the widths of the outer pipe 1, the filling layer 4, and the inner pipe 3. The connecting frames 5 are all fixedly connected to the inside of the slots 8. The slots 8 are all located in the middle of the side wall of the connecting flange 6 near the outer pipe 1. The connecting flange 6 and the connecting frame 5 are symmetrically arranged about the middle of the outer pipe 1. The slots 8 are all clearance-fitted with the connecting frame 5. The upper and lower ends of the composite air duct are sealed by the cooperation between the connecting flange 6 and the connecting frame 5. At the same time, it is convenient to splice and assemble multiple sets of composite air ducts in the future.

[0029] Working principle: After the composite pipe is assembled, the mounting frame 9 is placed inside the inner pipe 3 and the grip ring 11 is rotated. During the rotation of the grip ring 11, the bidirectional screw 10 rotates. The rotation of the bidirectional screw 10 causes the threaded plates 12 on the front and rear sides to move away from each other, thereby causing the support block 13 fixed to the threaded plate 12 to move outward. During the sliding process inside the opening 14, the support block 13 contacts and squeezes the inner wall of the inner pipe 3, thereby supporting the inner wall of the composite air duct. This eliminates the need for drilling, reduces the difficulty of supporting the composite air duct, and improves the sealing performance of the composite air duct.
