Description

Technical Field

[0001] This utility model relates to the field of wind speed detection technology, and in particular to an angular displacement and wind speed adjustment device. Background Technology

[0002] A wind speed adjustment device is a device used to regulate airflow speed. It consists of a mechanical structure and drive components, and is adjustable. It has a wind adjustment mechanism and control components. Some of them have precise speed control and stable operation functions. The core is designed with a blade and transmission structure adjustment system, which can change the size of the airflow channel and control the wind speed. It is used in ventilation equipment and airflow control scenarios to provide support for airflow speed regulation and stable output.

[0003] Angle displacement and wind speed adjustment devices are designed to solve the problem of airflow direction and speed control. In ventilation and food heat preservation scenarios, unstable airflow can lead to uneven temperature and poor performance. The device adjusts the angle through gear transmission, changes the channel size through blade structure, and is fixed in place with stop components to prevent angle deviation and wind speed fluctuation. It can also adapt to the needs of different scenarios and improve the accuracy and stability of airflow control. It is the core design of airflow equipment.

[0004] When using angular displacement and wind speed adjustment devices for airflow control, the wind speed is difficult to control, and the requirements vary greatly in different scenarios. Fixed output cannot be adapted, affecting the performance. In existing technologies, wind speed can be adjusted by using different motor powers to change the airflow output intensity and adapt to the needs of some scenarios, which solves the problem of single wind speed to a certain extent. However, in actual use, when the working conditions change, the power adjustment response is lagging, resulting in airflow fluctuations, unstable wind speed, insufficient control accuracy, and inability to accurately match the requirements.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: an angle displacement and wind speed adjustment device, including a housing 1, a connecting rod 2 fixedly connected to the left side of the housing 1, an air adjustment mechanism 3 provided inside the housing 1, the air adjustment mechanism 3 is used to adjust the air outlet speed, and an angle adjustment mechanism 4 is provided on the left side of the connecting rod 2, the angle adjustment mechanism 4 is used to adjust the air outlet angle.

[0035] The air conditioning mechanism 3 includes a support column 31, the upper and lower sides of which are fixedly connected to the upper and lower sides of the inner side of the outer shell 1, respectively. A frustum 32 is fixedly connected to the right side of the middle part of the outer wall of the support column 31. Multiple sealing blades 33 are rotatably connected to the outer wall of the frustum 32. A connecting rod 34 is fixedly connected to the opposite side of the multiple sealing blades 33. A rotating component 35 is provided on the opposite side of the multiple connecting rods 34. A control component 36 is provided on the top of the outer wall of the rotating component 35. A drive component 37 is provided on the bottom left side of the inner wall of the outer shell 1.

[0036] Specifically, the upper and lower sides of the support column 31 are fixedly connected to the upper and lower sides of the inner side of the outer shell 1, respectively. The support column 31 provides the installation support base for other components of the air regulating mechanism 3. A frustum 32 is fixedly connected to the right side of the middle of the outer wall of the support column 31. Multiple sealing blades 33 are rotatably connected to the outer wall of the frustum 32. The frustum 32 provides the axial positioning for the rotation of the sealing blades 33. Connecting rods 34 are fixedly connected to the opposite sides of the multiple sealing blades 33. The rotation state of the sealing blades 33 is transmitted to the rotating component 35 through the connecting rods 34. Rotating components 35 are provided on the opposite sides of the multiple connecting rods 34. The rotating component 35 receives the force transmitted by the connecting rods 34 and converts it into its own rotational action. A control component 36 is provided on the top of the outer wall of the rotating component 35. The control component 36 is linked with the rotating component 35. The rotation range of the sealing blades 33 is limited by controlling the rotation angle of the rotating component 35. A drive component 37 is provided on the bottom left side of the inner wall of the outer shell 1. After the drive component 37 is started, it outputs driving force, which is transmitted to the control component 36.

[0037] When airflow adjustment is needed, the drive assembly 37 starts operating, transmitting its driving force to the control assembly 36. Under this driving force, the control assembly 36 drives the rotating assembly 35 to rotate. As the rotating assembly 35 rotates, it pulls or pushes the sealing blades 33 via the connecting rod 34, causing the sealing blades 33 to rotate around the outer wall of the frustum 32. Through the linkage between the rotating assembly 35 and the connecting rod 34, the sealing blades 33 rotate around the frustum 32. As the sealing blades 33 rotate, the gaps between them change. When the sealing blades 33 move closer together, the gaps decrease, narrowing the airflow channel. When the sealing blades 33 move further apart... When the direction of rotation is away, the gap between the multiple closed blades 33 increases, and the airflow passage becomes wider. Through the rotation of the closed blades 33 and the change in gap, the airflow inside the outer shell 1 is regulated. During the rotation, the control component 36 always limits the rotation angle of the rotating component 35 to ensure that the rotation of the closed blades 33 does not exceed the preset range. By limiting the angle of the rotating component 35, the rotation range of the closed blades 33 is controllable. Throughout the process, the support column 31 remains fixed, providing stable support for the frustum 32 and the closed blades 33. Through the fixed support of the support column 31 and the coordinated movement of other components, the overall function of the air conditioning mechanism 3 in stabilizing and regulating the airflow speed is achieved.

Gear 42 can rotate around the axis of support rod 41. Toothed push rod 43 is meshed with the left side of the outer wall of gear 42. The linear motion of toothed push rod 43 is transmitted to gear 42 through the teeth and converted into the rotational motion of gear 42. Gear 44 is meshed with the bottom right side of the outer wall of toothed push rod 43. The rotation of gear 44 drives toothed push rod 43 to move linearly through the teeth.

A sealing component 49 is provided around rotating frame 47. The sealing component 49 is responsible for sealing the whole and plays a protective role.

[0040] When angle adjustment is required, rotate the adjustment knob 46. The knob 46 drives the support rod 45 to rotate, which in turn drives the gear 44 to rotate synchronously. Through the meshing of the gear 44 and the toothed push rod 43, the toothed push rod 43 achieves linear motion. During this linear motion, the toothed push rod 43 meshes with the gear 42. Through the linear motion of the toothed push rod 43 and the meshing of the gear 42, the gear 42 rotates around the support rod 41. When the gear 42 rotates, it drives the support rod 41 and connecting rod 2 to change their angle. During the rotation of rod 45, rotating frame 47 rotates synchronously. When rotating frame 47 rotates, the sealing component 49 on its periphery moves with rotating frame 47 to adjust the sealing coverage area. Through the rotation of rotating frame 47 and the position adjustment of sealing component 49, the sealing range adaptation effect is achieved during the angle adjustment process. When the angle is adjusted to the target position, stop component 48 is activated and restricts the rotation of rod 45. By restricting the rotation of rod 45 by stop component 48, the positions of gear 44, toothed push rod 43 and gear 42 are fixed.

The control assembly 36 includes a connecting platform 361, the bottom of which is fixedly connected to the top of the outer wall of the annular slide rail 353. The movement of the annular slide rail 353 drives the connecting platform 361 to move. A rotating frame 362 is rotatably connected to the top of the connecting platform 361. When the connecting platform 361 moves, it pushes the rotating frame 362 to rotate. A toothed push rod 3 is fixedly connected to the front side of the outer wall of the rotating frame 362. 63. When the rotating frame 362 rotates, it drives the toothed push rod 363 to move linearly. The front left side of the outer wall of the toothed push rod 363 is meshed with a gear 364. The linear motion of the toothed push rod 363 drives the gear 364 to rotate through the tooth transmission. The top of the gear 364 is fixedly connected to a rotating rod 365.

[0043] When drive adjustment is required, motor 372 starts, and the rotating shaft of motor 372 drives fan blade 373 to rotate. Through the power output of motor 372 and the rotation of fan blade 373, the driving force is generated and transmitted. The airflow generated by the rotation of fan blade 373 pushes push plate 367 to slide. When push plate 367 slides, it drives rotating rod 365 to rotate. Through the linkage between the sliding of push plate 367 and rotating rod 365, the rotation of rotating rod 365 is realized. The rotation of rotating rod 365 drives gear 364 to rotate synchronously.

The top of the vertical rod 7 is fixedly connected to a base 8. The base 8 provides bottom support for the vertical rod 7.

[0046] Once the angle is adjusted to the target position, support rod 45 stops rotating. Spring 484 pushes card 482 to rotate around support rod 483, causing card 482 to engage with the teeth of ratchet 481. Through the elastic force of spring 484 and the engagement of card 482 with ratchet 481, support rod 45 is stopped and fixed. Rotating frame 47 remains stationary. Support rod 45 stops rotating inside rotating frame 47. Protective shell 491 pushes push plate 492 to slide inside it according to the angle adjustment requirements. Through the stationary fixation of rotating frame 47 and the sliding of push plate 492, the sealing range changes synchronously with the angle adjustment. When rotating wheel 6 rotates, it drives support rod 5 to swing. When the support rod 2 swings, the connecting rod 2 changes its angle. The angle adjustment of the connecting rod 2 is achieved by the rotation of the rotating wheel 6 and the swing of the support rod 2. When the rotating wheel 6 rotates, it pulls the vertical rod 7 to swing. During the swing of the vertical rod 7, the base 8 remains fixed and supported. The rotation of the rotating wheel 6 and the swing of the vertical rod 7 provide auxiliary support for the angle adjustment of the connecting rod 2. The outer frame 486 fixes the position of the card 482 and the spring 484 through the support rod 2 483 and the support rod 3 485, ensuring that the stop component 48 continuously applies a stopping force to the support rod 1 45. Through the fixed support of the outer frame 486 and the continuous action of the stop component 48, the overall function of the angle adjustment mechanism 4 is to stably maintain the current angle.

[0047] Working Principle: After the device is started, if wind speed adjustment is required, the drive assembly 37 begins to operate. The base 371 in the drive assembly 37 is fixed to the bottom left side of the inner wall of the outer casing 1, providing a stable mounting base for the motor 372. After the motor 372 starts, its rotating shaft drives the fan blades 373 to rotate. The motor 372 continuously outputs power, and the fan blades 373 rotate at high speed, generating a strong airflow. This airflow is the initial driving force for the entire wind regulation mechanism 3. The airflow generated by the rotation of the fan blades 373 directly acts on the push plate 367 in the control assembly 36. The push plate 367 is located inside the front side of the protective casing 366 and can slide freely within it. The airflow pushes the push plate 367 to slide, and the sliding of the push plate 367 in turn drives the closely connected... Rotating rod 365 rotates, and gear 364 is fixed at the top of rotating rod 365. The rotation of rotating rod 365 causes gear 364 to rotate synchronously. The rotation of gear 364 drives toothed push rod 363 to move linearly through tooth transmission. The left side of the front end of the outer wall of toothed push rod 363 meshes with gear 364. When gear 364 rotates, toothed push rod 363 will make linear displacement along a specific direction under this meshing action. The linear movement of toothed push rod 363 pushes rotating frame 362 to rotate. Rotating frame 362 is connected to annular slide rail 353 through connecting platform 361. The rotation of rotating frame 362 then drives connecting platform 361 to move. The movement of connecting platform 361 in turn causes annular slide rail 353 to move.

[0048] The annular slide rail 353 contains multiple rollers 354, which are fixedly connected by support columns 355. The support columns 355 provide a stable mounting base for the rollers 354, ensuring that the rollers 354 can roll smoothly inside the annular slide rail 353. When the annular slide rail 353 moves, the rollers 354 roll accordingly, ensuring the smooth movement of the annular slide rail 353. The movement of the annular slide rail 353 is transmitted to the cuboids 351 through the cylinders 352. The multiple cuboids 351 are rotatably connected to each other by multiple connecting rods 34. On one side, cylinder 352 is slidably connected to cuboid 351. When the annular slide rail 353 moves, it pushes cylinder 352 to move, and cylinder 352 then pushes cuboid 351 to rotate. The rotation of cuboid 351 drives the closing blade 33 to adjust its angle through connecting rod 34. The closing blade 33 is rotatably connected to frustum 32, which is fixed to support column 31. The upper and lower sides of support column 31 are fixedly connected to the upper and lower sides inside the outer casing 1, respectively, providing a stable installation support foundation for the entire air conditioning mechanism 3. When cuboid 351 rotates, connecting rod 34 transmits force to closing blade 3. 3. The sealing blade 33 rotates around the outer wall of the frustum 32. As the sealing blade 33 rotates, the gap between the multiple sealing blades 33 changes. When the sealing blades 33 rotate towards each other, the gap between the multiple sealing blades 33 decreases, the airflow passage narrows, the airflow per unit time decreases, and the air outlet speed decreases. When the sealing blades 33 rotate away from each other, the gap between the multiple sealing blades 33 increases, the airflow passage widens, the airflow per unit time increases, and the air outlet speed increases. Throughout the entire air conditioning process, the control component 36 always limits the rotation angle of the rotating component 35. The rotation angle of the rotating frame 362, which is rotatably connected to the top of the connecting platform 361, is limited by the toothed push rod 363. The movement of the toothed push rod 363 is controlled by the gear 364, the push plate 367, and the rotating rod 365. Through this series of linkages and controls, it is ensured that the rotation of the sealing blade 33 will not exceed the preset range, thereby achieving precise and stable adjustment of the airflow and thus achieving the purpose of adjusting the air outlet speed.

[0049] The angle adjustment mechanism 4 is used to adjust the air outlet angle. Its main components include support rod 1 41, gear 2 42, toothed push rod 2 43, gear 3 44, support rod 1 45, adjustment knob 46, rotating frame 2 47, stop assembly 48, sealing assembly 49, support rod 2 5, rotating wheel 6, vertical rod 7, and base 8. When the air outlet angle needs to be adjusted, the operator rotates the adjustment knob 46. The adjustment knob 46 is fixedly connected to the rear side of support rod 1 45. The rotation of the adjustment knob 46 directly drives support rod 1 45 to rotate. Support rod 1 45 passes through the interior of gear 3 44. When support rod 1 45 rotates, it drives gear 3 44 to rotate synchronously. Gear 3 44 meshes with the bottom right side of the outer wall of toothed push rod 2 43. The rotation of gear 3 44 drives toothed push rod 2 43 to move linearly through its teeth. The linear movement of toothed push rod 2 43 meshes with gear 2 42. Gear 2 42 is fixed in the middle of the outer wall of support rod 1 41. 41 is fixedly connected to the front and rear ends of the left side inside the connecting rod 2. When the toothed push rod 43 moves linearly, it meshes with the gear 42, causing the gear 42 to rotate around the support rod 41. The rotation of the gear 42 causes the support rod 41 and the connecting rod 2 to change their angle. During this process, the rotating frame 47 set on the front side of the outer wall of the support rod 45 will rotate synchronously with the support rod 45. The top of the rotating frame 47 is equipped with a sealing component 49. The front side of the top end of the protective shell 491 in the sealing component 49 is fixed to the top of the rotating frame 47. The front side of the protective shell 491 is slidably connected to the push plate 492 inside. When the rotating frame 47 rotates, the protective shell 491 moves accordingly, pushing the push plate 492 to slide inside, thereby adjusting the sealing coverage area and achieving the sealing range adaptation effect during the angle adjustment process, effectively protecting the internal mechanical structure from interference from external dust and debris.

[0050] Once the angle is adjusted to the target position, the stop assembly 48 begins to function. The ratchet 481 in the stop assembly 48 is internally inserted through the middle of the outer wall of the first support rod 45. When the first support rod 45 rotates, it drives the ratchet 481 to rotate synchronously. A clip 482 is provided on the outer wall of the ratchet 481, and a second support rod 483 passes through the clip 482. The second support rod 483 provides an axis for the rotation of the clip 482. A spring 484 is fixedly connected to the rear bottom of the clip 482. The bottom of the spring 484 is fixed... The first support rod 485 is fixedly connected to the third support rod 485. An outer frame 486 is fixedly connected to the front of the third support rod 485. The outer frame 486 provides a mounting carrier for the second support rod 483 and the third support rod 485, ensuring the stability of the entire stop assembly 48 structure. When the first support rod 45 stops rotating, the spring 484, due to its own elasticity, pushes the card 482 to rotate around the second support rod 483, causing the card 482 to engage with the teeth of the ratchet 481. Through the elasticity of the spring 484 and the interaction between the card 482 and the ratchet... The close cooperation of 481 achieves the stop and fixation of support rod 45. At this time, rotating frame 47 remains stationary and fixed. Support rod 45 stops rotating inside rotating frame 47, thereby fixing the positions of gear 3 44, toothed push rod 2 43, and gear 2 42, thus stabilizing the currently adjusted air outlet angle. In addition, support rod 2 5 is rotatably connected inside connecting rod 2. A rotating wheel 6 is set in the middle of the outer wall of support rod 2 5. A vertical rod 7 is fixedly connected to the bottom of rotating wheel 6, and a base 8 is fixedly connected to the top of vertical rod 7. When the angle adjustment mechanism 4 operates, rotating wheel 6 rotates and drives support rod 2 5 to swing. The swing of support rod 2 5 causes connecting rod 2 to change its angle, realizing the angle adjustment action of connecting rod 2. At the same time, rotating wheel 6 pulls vertical rod 7 to swing. During the swing of vertical rod 7, base 8 always maintains fixed support, providing reliable auxiliary support for the angle adjustment of connecting rod 2, and enhancing the stability and reliability of the entire angle adjustment process.
