Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to an adjustable-angle louvered airflow distribution device. Background Technology

[0002] A louvered air vent is a type of air distributor. Common types of louvered air vents include single-layer louvered air vents, double-layer louvered air vents, side-wall grille air vents, and slotted grille air vents. Single-layer louvered air vents are frequently used as return air vents, sometimes in conjunction with aluminum alloy mesh filters or nylon filters. Double-layer louvered air vents consist of two layers of blades; the front layer is adjustable, while the rear layer is fixed. A split-leaf multi-blade airflow regulating valve can be configured to adjust the airflow.

[0003] Uneven airflow from louvered vents can occur due to issues with the vent structure itself, upstream duct system design, or installation, leading to decreased comfort, noise, and poor air quality. Therefore, an airflow equalization device needs to be installed inside the louvered vent. Guide vanes or baffles are one end of this device. While some commercially available baffles offer adjustable angles, allowing for angle adjustment between adjacent baffles via gears, these only adjust the angle; the distance between the baffles remains constant. This makes it difficult to precisely regulate the airflow between the baffles within the louvered vent, thus hindering the more even distribution of airflow across the entire outlet surface. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-angle louvered airflow distribution device that can adjust the distance and angle between the guide plates, thereby precisely adjusting the airflow between the guide plates in the louvered airflow and guiding the airflow to flow more evenly to the entire air outlet surface.

[0005] To achieve the above objectives, an adjustable-angle louvered airflow distribution device is provided, comprising a mounting plate and a ventilation duct. The mounting plate is fixedly connected to one end of the ventilation duct, and the ventilation duct passes through the middle of the mounting plate. A plurality of blades are equidistantly arranged on the inner wall of the ventilation duct. A plurality of first openings and a plurality of guide grooves are equidistantly arranged on the surface of the mounting plate, with the guide grooves located directly below the first openings. An adjustment mechanism is provided at the end of the mounting plate away from the ventilation duct, and the adjustment mechanism is slidably connected to the mounting plate. A lower housing is fixedly connected to the lower end of the ventilation duct. A plurality of airflow distribution mechanisms are equidistantly arranged inside the ventilation duct. A plurality of second openings are equidistantly arranged at both the upper and lower ends of the ventilation duct. The upper end of each airflow distribution mechanism passes through the second opening into the upper housing, and the lower end of each airflow distribution mechanism extends through the second opening into the lower housing. A slide rail is fixedly connected to the upper end of the ventilation duct, and the upper end of each airflow distribution mechanism is slidably connected to the slide rail. A guide rail is fixedly connected to the bottom of the lower housing, and the lower end of each airflow distribution mechanism is slidably connected to the guide rail. The end of each airflow distribution mechanism facing the mounting plate passes through the first opening and is connected to the adjustment mechanism. It can adjust the distance and angle between the guide vanes, thereby precisely regulating the airflow between the guide vanes in the louvered air outlet and guiding the airflow to flow more evenly to the entire air outlet surface.

[0006] According to the adjustable-angle louvered airflow distribution device, the adjustment mechanism consists of a rotating sleeve, a knob, a locking bolt, and a connecting plate. The knob is located in the middle of the rotating sleeve, passes through the middle of the rotating sleeve, and is rotatably connected to the rotating sleeve. The middle of the end of the knob facing the mounting plate is fixedly connected to the airflow distribution mechanism. The connecting plate is fixedly connected to the lower end of the rotating sleeve and is slidably connected to the mounting plate. The locking bolt is located at the end of the connecting plate away from the mounting plate, passes through the connecting plate, and is threadedly connected to the connecting plate. The locking bolt extends into the guide groove and is slidably connected to the guide groove. The knob adjusts the airflow distribution mechanism, changing the distance between adjacent airflow distribution mechanisms and the angle of the airflow blowing from the surface of the airflow distribution mechanism. The locking bolt uses friction to fix the adjustment mechanism to the surface of the mounting plate, preventing the airflow distribution mechanism from moving.

[0007] According to the adjustable-angle louvered airflow distribution device, the airflow distribution mechanism consists of a first slider, a guide plate, a sealing mechanism, a worm gear, a support mechanism, and a worm wheel. The guide plate is disposed in the ventilation duct, and a rotating shaft is connected to the guide plate by a key, with the rotating shaft passing through the guide plate. The first slider is slidably connected to the inner wall of the slide rail, and the upper end of the rotating shaft passes through the middle of the first slider and is rotatably connected to the first slider. Two sealing mechanisms are fixedly connected to both the upper and lower ends of the guide plate, and the guide plate is located between the two sealing mechanisms. The sealing mechanism slides against the inner wall of the ventilation duct and seals the second opening. The support mechanism is disposed on the outside of the guide rail and is slidably connected to the guide rail. The worm wheel is installed on the upper end of the support mechanism, and the lower end of the rotating shaft of the guide plate passes through the middle of the worm wheel and is fixedly connected to the worm wheel. The worm gear is disposed on one side of the worm wheel and meshes with the worm wheel. One end of the worm gear is rotatably connected to the support mechanism, and the other end of the worm gear passes through the first opening and is fixedly connected to the knob. The worm gear and worm shaft work together to adjust the angle of the guide plate with the knob. The first slider and the support mechanism guide the movement of the airflow distribution mechanism. The knob moves the support mechanism through the worm shaft, causing the guide plate to move. The sealing mechanism seals the second opening to prevent airflow in the louvered vent from leaking through the second opening.

[0008] According to the adjustable-angle louvered airflow distribution device, the sealing mechanism consists of a sleeve, a spring, and a sliding rod. The sleeve has openings at its bottom and at one end facing the guide plate. The sliding rod is located within the sleeve and slidably connected to the inner wall of the sleeve, with its lower end passing through the opening at the bottom of the sleeve. The sliding rod and the lower end of the sleeve are slidably connected to the inner wall of the ventilation duct, and one end of the sliding rod is fixedly connected to the guide plate. The spring is fixedly connected to the end of the sliding rod away from the guide plate, and the other end of the spring is fixedly connected to the inner wall of the sleeve. When adjacent airflow distribution mechanisms approach each other, the sealing mechanisms on the surfaces of the adjacent airflow distribution mechanisms contact each other, causing the sliding rod to enter the sleeve. After the sealing mechanisms on the surfaces of the adjacent airflow distribution mechanisms move away, the spring pushes the sliding rod back to its original position.

[0009] According to the adjustable-angle louvered airflow distribution device, the support mechanism consists of a support plate, a sliding sleeve, and a support block. The guide rail passes through the sliding sleeve. The support plate is fixedly connected to the side of the sliding sleeve facing the mounting plate, and the worm gear is located on the upper end of the mounting plate. The support block is fixedly connected to the upper end of the sliding sleeve, and one end of the worm is rotatably connected to the middle of the support block. This supports the worm, ensuring that the positions of the worm gear and the worm are relatively fixed.

[0010] According to the adjustable-angle louvered airflow distribution device, the mounting plate has several equidistant distance scales on its surface away from the ventilation duct, and these distance scales are located above the first opening. The adjustment mechanism calculates the spacing between adjacent guide plates using these distance scales. The rotating sleeve has angle adjustment scales on its side away from the mounting plate, facilitating the adjustment of the guide plate's tilt angle by the operator. This allows the operator to easily adjust the airflow distribution mechanism.

[0011] The above solution has the following advantages: by adjusting the mechanism, several airflow distribution mechanisms can be independently controlled, the distance between the airflow distribution mechanisms can be adjusted, and the angle of the airflow distribution mechanisms can be adjusted. The cooperation of the worm gear and worm allows the knob to adjust the angle of the guide plate, thereby precisely adjusting the airflow between the guide plates in the louvered air outlet and guiding the airflow to flow more evenly to the entire air outlet surface.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] Reference Figure 1-7 This utility model discloses an adjustable-angle louvered airflow distribution device, comprising a mounting plate 1 and a ventilation pipe 7. The mounting plate 1 is fixedly connected to one end of the ventilation pipe 7, and the ventilation pipe 7 passes through the middle of the mounting plate 1. A plurality of blades 2 are equidistantly arranged on the inner wall of the ventilation pipe 7. A plurality of first openings 3 and a plurality of guide grooves 5 are equidistantly arranged on the surface of the mounting plate 1, with the guide grooves 5 located directly below the first openings 3. An adjustment mechanism 4 is provided at the end of the mounting plate 1 away from the ventilation pipe 7, and the adjustment mechanism 4 is slidably connected to the mounting plate 1. A lower housing 6 is fixedly connected to the lower end of the ventilation pipe 7. The ventilation pipe 7 contains equidistantly arranged... A plurality of airflow equalization mechanisms 10 are provided. A plurality of second openings 28 are provided at equal intervals at both the upper and lower ends of the ventilation pipe 7. The upper end of the airflow equalization mechanism 10 passes through the second opening 28 into the upper housing 8, and the lower end of the airflow equalization mechanism 10 passes through the second opening 28 and extends into the lower housing 6. A slide rail 11 is fixedly connected to the upper end of the ventilation pipe 7, and the upper end of the airflow equalization mechanism 10 is slidably connected to the slide rail 11. A guide rail 9 is fixedly connected to the bottom of the lower housing 6, and the lower end of the airflow equalization mechanism 10 is slidably connected to the guide rail 9. The end of the airflow equalization mechanism 10 facing the mounting plate 1 passes through the first opening 3 and is connected to the adjustment mechanism 4.

[0025] The adjusting mechanism 4 consists of a rotating sleeve 12, a knob 13, a locking bolt 14, and a connecting plate 15. The knob 13 is located in the middle of the rotating sleeve 12, passing through the middle of the sleeve and rotatably connected to it. The middle of the end of the knob 13 facing the mounting plate 1 is fixedly connected to the airflow distribution mechanism 10. The connecting plate 15 is fixedly connected to the lower end of the rotating sleeve 12 and slidably connected to the mounting plate 1. The locking bolt 14 is located at the end of the connecting plate 15 away from the mounting plate 1, passing through the connecting plate 15 and threadedly connected to it. The locking bolt 14 extends into the guide groove 5 and slidably connects to it. The knob 13 adjusts the airflow distribution mechanism 10, changing the distance between adjacent airflow distribution mechanisms 10 and the angle of the airflow blowing from the surface of the airflow distribution mechanism 10. The locking bolt 14 uses friction to fix the adjusting mechanism 4 to the surface of the mounting plate 1, preventing the airflow distribution mechanism 10 from moving.

[0026] The airflow distribution mechanism 10 consists of a first slider 16, a guide plate 17, a sealing mechanism 18, a worm gear 19, a support mechanism 20, and a worm wheel 21. The guide plate 17 is located in the ventilation pipe 7. A rotating shaft is connected to the guide plate 17 by a key, and the rotating shaft passes through the guide plate 17. The first slider 16 is slidably connected to the inner wall of the slide rail 11, and the upper end of the rotating shaft passes through the middle of the first slider 16 and is rotatably connected to the first slider 16. Two sealing mechanisms 18 are fixedly connected to both the upper and lower ends of the guide plate 17, and the guide plate 17 is located between the two sealing mechanisms 18. Between points 8, the sealing mechanism 18 slides against the inner wall of the ventilation duct 7 and seals the second opening 28. The support mechanism 20 is located outside the guide rail 9 and is slidably connected to the guide rail 9. The worm gear 21 is installed on the upper end of the support mechanism 20, and the lower end of the rotating shaft of the guide plate 17 passes through the middle of the worm gear 21 and is fixedly connected to the worm gear 21. The worm 19 is located on one side of the worm gear 21 and meshes with the worm gear 21. One end of the worm 19 is rotatably connected to the support mechanism 20, and the other end of the worm 19 passes through the first opening 3 and is fixedly connected to the knob 13. The cooperation of the worm gear 21 and the worm 19 allows the knob 13 to adjust the angle of the guide plate 17. The first slider 16 and the support mechanism 20 guide the movement of the airflow distribution mechanism 10, and the knob 13 moves the support mechanism 20 through the worm 19, causing the guide plate 17 to move. The sealing mechanism 18 seals the second opening 28 to prevent airflow in the louvered air outlet from leaking through the second opening 28.

[0027] The sealing mechanism 18 consists of a sleeve 22, a spring 23, and a sliding rod 24. The sleeve 22 has openings at its bottom and at one end facing the guide plate 17. The sliding rod 24 is located within the sleeve 22 and is slidably connected to the inner wall of the sleeve 22. The lower end of the sliding rod 24 passes through the bottom opening of the sleeve 22. The sliding rod 24 and the lower end of the sleeve 22 are slidably connected to the inner wall of the ventilation pipe 7. One end of the sliding rod 24 is fixedly connected to the guide plate 17. The spring 23 is fixedly connected to the end of the sliding rod 24 away from the guide plate 17, and the other end of the spring 23 is fixedly connected to the inner wall of the sleeve 22. When adjacent airflow distribution mechanisms 10 approach each other, the sealing mechanisms 18 on the surfaces of the adjacent airflow distribution mechanisms 10 come into contact, causing the sliding rod 24 to enter the sleeve 22. After the sealing mechanisms 18 on the surfaces of the adjacent airflow distribution mechanisms 10 move away, the spring 23 pushes the sliding rod 24 back to its original position.

[0028] The support mechanism 20 consists of a support plate 25, a sliding sleeve 26, and a support block 27. A guide rail 9 passes through the sliding sleeve 26. The support plate 25 is fixedly connected to the side of the sliding sleeve 26 facing the mounting plate 1, and the worm gear 21 is located at the upper end of the mounting plate 1. The support block 27 is fixedly connected to the upper end of the sliding sleeve 26, and one end of the worm 19 is rotatably connected to the middle of the support block 27. This supports the worm 19, ensuring that the positions of the worm gear 21 and the worm 19 are relatively fixed.

[0029] The mounting plate 1 has several equidistant distance markings on its surface away from the ventilation duct 7, and these markings are located above the first opening 3. The adjustment mechanism 4 calculates the distance between adjacent guide plates 17 using these markings. The rotating sleeve 12 has angle adjustment markings on its side away from the mounting plate 1, allowing operators to easily adjust the tilt angle of the guide plates 17. This also facilitates the adjustment of the airflow distribution mechanism 10 by operators using the adjustment mechanism 4.

[0030] Working principle: In use, the airflow distribution mechanism 10 is moved by the adjustment mechanism 4. The support mechanism 20 of the airflow distribution mechanism 10 slides on the guide rail 9, the first slider 16 moves in the slide rail 11, and the locking bolt 14 slides in the guide groove 5. After the movement is completed, the locking bolt 14 is rotated to increase the friction between the locking bolt 14 and the mounting plate 1 to fix the airflow distribution mechanism 10. The worm gear 19 is rotated by the knob 13. The cooperation between the worm wheel 21 and the worm gear 19 causes the guide plate 17 to rotate, thereby adjusting the angle of the guide plate 17.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
