Description

Technical Field

[0001] This utility model relates to the field of air valves, specifically an air valve adjustment mechanism for an air outlet. Background Technology

[0002] As a key component of air conditioning systems, air valves are mainly used to control the direction, flow rate, and pressure of air circulation, and are widely used in various ventilation, air conditioning, purification projects, and industrial exhaust systems.

[0003] The internal structure of an air valve typically contains two important components: an air guide plate and a flow control plate. The air guide plate is usually located on the outermost layer of the air valve, and its main function is to control the direction of air discharge. Through reasonable angle design, the airflow can be guided to a specific area to achieve a more uniform air distribution. The flow control plate is used to control the air volume. It is located inside the air valve, and personnel can operate the flow control plate with the help of control components. By changing the spacing between the flow control plates, the amount of air discharged from the air outlet duct can be adjusted to achieve the purpose of supplying air as needed.

[0004] Because the control components inside the air valve can only control a single function board, the other function board usually has to be fixed, resulting in low applicability of the air valve. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an air valve adjustment mechanism for an air outlet, so as to solve the technical problem that it is difficult for personnel to adjust the guide plate and control plate inside the air valve through a set of control components.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air valve adjustment mechanism for an air outlet, comprising an air valve frame, wherein multiple sets of guide plates and control plates are installed inside the air valve frame, and the guide plates are located inside the control plates; a knob is installed on one side of the air valve frame, a drive rod is fixed to one end of the knob, a second locking block is fixed to the outer wall of the drive rod, a drive column is sleeved on the outer wall of the second locking block, a drive assembly is installed on one side of the drive column, a first gear is connected to one end of the drive assembly, a first locking block is fixed to the end of the drive rod, a rotating column is provided on one side of the first locking block, a second bevel gear is installed at the end of the rotating column, an adjustment assembly is installed on one side of the second bevel gear, and a third gear is connected to one end of the adjustment assembly.

[0007] By adopting the above technical solution, the technical problem of difficulty in adjusting the guide plates and control plates inside the air valve using a set of control components is solved. When it is necessary to adjust the flow direction of the guide plates, the knob is rotated. The knob drives the drive column to rotate through the second locking block connected to the outer wall of the rotating rod. The rotating drive column drives a set of first gears to rotate through the drive component. The rotating first gear drives the adjacent first gears to rotate through the second gear, so that the multiple sets of guide plates rotate in the same direction, thereby changing the flow direction of multiple sets of guide plates. When it is necessary to adjust the air volume, the knob is pushed inward. The knob drives the first locking block into the rotating column through the drive rod, so that the drive rod can drive the rotating column to rotate. The rotating column drives multiple sets of third gears to rotate through the control component. The adjacent sets of control plates rotate in opposite directions, so that the included angle gap between the adjacent sets of control plates changes, thereby changing the air volume discharged from the air valve frame.

[0008] The present invention is further configured such that the driving assembly includes a first driving belt, a first connecting post is connected to the end of the first driving belt, a third bevel gear is fixed to the end of the first connecting post, a fourth bevel gear is connected to one side of the third bevel gear, a second connecting post is fixed to the end of the fourth bevel gear, a second driving belt is connected to one side of the second connecting post, and a third connecting post is provided at the end of the second driving belt.

[0009] Preferably, the drive column drives the first connecting column to rotate via the first drive belt, and the rotating first connecting column drives the second connecting column to rotate via the meshing connection of the third bevel gear and the fourth bevel gear, and the second connecting column drives the third connecting column to rotate via the second drive belt.

[0010] The present invention is further configured such that a first gear is connected to one end of the guide plate, and a second gear is installed on both sides of the first gear.

[0011] Preferably, a set of first gears drives an adjacent set of first gears to rotate through a second gear, so that multiple sets of guide plates connected to one end of multiple sets of first gears rotate in the same direction.

[0012] The present invention is further configured such that the control component includes a first bevel gear, one end of which is fixed with a rotating rod, and the end of the rotating rod is connected to a third gear.

[0013] Preferably, the rotating column is connected by the meshing of the first bevel gear and the second bevel gear, so that the rotating column drives the rotating rod to rotate, and the rotation of the rotating rod drives multiple sets of third gears to rotate.

[0014] The present invention is further configured such that one end of the flow control plate is connected to a set of third gears, and the multiple sets of third gears mesh with each other.

[0015] Preferably, multiple sets of third gears are connected by meshing, so that the multiple sets of third gears rotate synchronously, causing adjacent sets of flow control plates to rotate in opposite directions, thereby changing the included angle gap between adjacent sets of flow control plates.

[0016] The present invention is further configured such that the inner wall shape of the rotating column matches the shape of the first locking block, and the first locking block is configured as a regular hexagon.

[0017] Preferably, when the first locking block is inserted into the rotating column, the drive rod can drive the rotating column to rotate through the first locking block.

[0018] The present invention is further configured such that a slot is provided at the end of the inner wall of the rotating column, a guide post is installed at the end of the drive rod, and the end of the guide post is located inside the slot.

[0019] Preferably, the rotating column limits the movement of the drive rod through the guide column, so that the drive rod moves horizontally.

[0020] The present invention is further configured such that a rotating disk is fixed to the outer wall of the drive rod, a movable plate is sleeved on the outer wall of the rotating disk, and a spring is installed on one side of the movable plate.

[0021] Preferably, when the drive rod moves into the air valve frame, the drive rod compresses the spring through the moving plate. When the external thrust disappears, the spring in the compressed state drives the drive rod to reset through the moving plate. The rotating disk can ensure that the drive rod drives the moving plate to move, and the drive rod will not drive the spring to rotate when it rotates.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by setting up a guide plate, a drive assembly, a knob, and a drive rod, allows the guide plate's flow direction to be adjusted when needed. Rotating the knob causes the drive column to rotate via a second locking block connected to the outer wall of the rotating rod. The rotating drive column then drives a set of first gears to rotate via the drive assembly. The rotating first gears then drive adjacent first gears to rotate via second gears, resulting in multiple guide plates rotating in the same direction, thereby achieving the change of the flow direction of multiple guide plates.

[0024] 2. This utility model, by setting up a flow control plate, an adjustment component, a knob, a drive rod, a rotating column, and a first locking block, allows the airflow to be adjusted. When the airflow needs to be adjusted, the knob is pushed inward, and the knob, through the drive rod, inserts the first locking block into the rotating column, so that the drive rod can drive the rotating column to rotate. The rotating column, through the adjustment component, drives multiple sets of third gears to rotate, and adjacent sets of flow control plates rotate in opposite directions, thereby changing the included angle gap between adjacent sets of flow control plates and thus changing the airflow discharged from the air valve frame.

This device solves the technical problem that it is difficult for personnel to control the guide plates and control plates inside the damper using a set of control components. When it is necessary to adjust the flow direction of the guide plate 2... When adjusting the airflow, rotate knob 4. Knob 4 drives drive column 402 to rotate via second locking block 410 connected to the outer wall of rotating rod 401. The rotating drive column 402 drives a set of first gears 201 to rotate via drive assembly.

The rotating column 305 is connected to the first bevel gear 303 and the second bevel gear 304 through meshing, so that the rotating column 305 drives the rotating rod 302 to rotate, and the rotation of the rotating rod 302 drives multiple sets of third gears 301 to rotate.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 One end of the flow control plate 3 is connected to a set of third gears 301. Multiple sets of third gears 301 mesh with each other and are connected by meshing, so that multiple sets of third gears 301 rotate synchronously, causing adjacent sets of flow control plates 3 to rotate in opposite directions, thus changing the included angle gap between adjacent sets of flow control plates 3.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall of the rotating column 305 is provided with a slot 311, and the end of the drive rod 401 is equipped with a guide column 310, with the end of the guide column 310 located inside the slot 311. The rotating column 305 limits the movement of the drive rod 401 through the guide column 310, so that the drive rod 401 moves horizontally.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 4A rotating disk 309 is fixed to the outer wall of the drive rod 401. A movable plate 308 is sleeved on the outer wall of the rotating disk 309. A spring 307 is installed on one side of the movable plate 308. When the drive rod 401 moves into the air valve frame 1, the drive rod 401 compresses the spring 307 through the movable plate 308. When the external thrust disappears, the spring 307, which is in a compressed state, drives the drive rod 401 to reset through the movable plate 308. The rotating disk 309 can ensure that the drive rod 401 drives the movable plate 401 to move, and the drive rod 401 will not drive the spring 307 to rotate when it rotates.

[0043] Second embodiment:

[0044] Please see Figure 5 The outer wall of the drive rod 401 is fixed with a plug 5, and the outer wall of the air valve frame 1 is provided with a plug hole 501. Both the plug 5 and the plug hole 501 are set as regular hexagons, and the dimensions of the plug 5 and the plug hole 501 match. Before the drive rod 401 is pushed into the air valve frame 1, the plug 5 needs to be aligned with the plug hole 501. When the plug 5 is inserted into the plug hole 501, the first locking block 306 can be accurately inserted into the rotating column 305, which makes it convenient for personnel to adjust the flow control plate 3. The end of the plug hole 501 is connected to a rotating groove 502, and the diameter of the rotating groove 502 is larger than the diameter of the plug hole 501. When the plug 5 is moved into the rotating groove 502, the drive rod 401 can drive the plug 5 to rotate.

[0045] In practical operation, when it is necessary to change the direction of the exhaust airflow, firstly, rotate knob 4. Rotation 4 drives drive column 402 to rotate via second locking block 410. Drive column 402 drives first connecting column 404 to rotate via first drive belt 403. The rotating first connecting column 404 drives second connecting column 407 to rotate via meshing connection of third bevel gear 405 and fourth bevel gear 406. Second connecting column 407 drives third connecting column 409 to rotate via second drive belt 408. Third connecting column 409 drives a set of first gears 201 to rotate. A set of first gears 201 drives an adjacent set of first gears 201 to rotate via second gear 202, causing multiple sets of guide plates 2 connected to one end of multiple sets of first gears 201 to rotate in the same direction. When it is necessary to control the airflow, rotate knob 4. The knob 4 is pushed into the air valve frame 1. The knob 4 inserts the first locking block 306 connected to its end into the rotating column 305 through the drive rod 401. The movement of the drive rod 401 moves the second locking block 410 out of the drive column 402. The drive rod 401 compresses the compression spring 307 through the moving plate 308. Then the knob 4 is rotated. The knob 4 drives the first locking block 306 to rotate through the drive rod 401. The first locking block 306 drives the rotating column 305 to rotate. The rotating column 305 is connected by the meshing of the first bevel gear 303 and the second bevel gear 304, so that the rotating column 305 drives the rotating rod 302 to rotate.
