Technical Field

[0001] This utility model relates to the field of wind tunnel support technology, and in particular to a multi-directional rotating device for wind tunnel supports. Background Technology

[0002] During the assembly process, the ventilation duct needs to be fixed to the building with the help of a bracket.

[0003] A search revealed a short duct fan bracket (publication number: CN221074768U), comprising a fan housing, inside which fan blades and a motor are installed. A suspension structure is mounted on the fan housing via a connecting structure, and the suspension structure includes a suspension rod, a fixed plate, a fixed rod, a lifting rod, a crossbar, and an adjusting rod. The suspension rod is fixedly connected to the fixed plate, the fixed rod is mounted on the suspension rod, the crossbar is fixed between two lifting rods, and the adjusting rod is fixed on the crossbar and passes through the fixed rod. The connecting structure includes a fixed seat, a rotating shaft, and a rotating plate. The rotating shaft is mounted on the fan housing via the fixed seat, the rotating plate is sleeved on the rotating shaft, and the rotating plate is located at the lower end of the lifting rod.

[0004] In the existing technology, after the air duct is installed with the bracket, the blowing angle of the air duct is fixed. It is difficult to adjust the blowing angle of the air duct according to different usage environments, which limits the flexibility of use.

[0005] Therefore, we propose a multi-directional rotation device for the ventilation duct support. Utility Model Content

[0006] The present invention mainly solves the technical problem of fixing the blowing angle of the air duct mentioned above, and provides a multi-directional rotating device for the air duct support.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a multi-directional rotating device for a ventilation duct support, comprising: The main support frame has a clamp on one side, and the fan is installed on the clamp. The main support has adjustment components on its top and side walls for adjusting the horizontal angle of the main support and the pitch angle of the clamp, respectively. The adjustment components include a mounting plate, a rotating seat, and a limiting sleeve. A mounting plate is fixedly installed on the side wall of the main support. The rotating seat is fixedly connected to the clamp and rotatably connected to the mounting plate. The limiting sleeve is elastically connected to the mounting plate and engages with the rotating seat.

[0008] In a preferred embodiment of this utility model, both the mounting plate and the rotating seat are circular plates. The mounting plate is welded with a rotating shaft, and the rotating seat has a shaft hole. The rotating shaft passes through the shaft hole and is limited by a retaining spring.

[0009] In a preferred embodiment of this utility model, the limiting sleeve is annular, the inner diameter of the limiting sleeve is equal to the outer diameter of the mounting base plate, and the limiting sleeve can slide radially along the circumferential surface of the mounting base plate.

[0010] In a preferred embodiment of this utility model, the adjusting component further includes a thrust groove and a limiting protrusion. The limiting sleeve is fixedly installed with the limiting protrusion, and the rotating seat has several thrust grooves. The limiting protrusion can be inserted into the thrust groove to restrict the rotation of the rotating seat.

[0011] In a preferred embodiment of this utility model, the thrust groove is formed on the circumferential surface of the rotating seat, and the thrust groove is a semi-circular groove. The limiting protrusion is fixedly installed on the inner circumferential surface of the limiting sleeve, and the limiting protrusion is in clearance fit with the thrust groove.

[0012] In a preferred embodiment of this utility model, the adjusting component further includes a spring, which is fixedly installed on the outer circumferential surface of the limiting sleeve, and the end of the spring is fixedly installed on the main bracket, forming a wave-shaped plate.

[0013] As a preferred embodiment of the present invention, the adjusting component further includes a lateral threaded hole. The circumferential surface of the limiting sleeve has a lateral threaded hole, and a bolt is provided in the lateral threaded hole. The circumferential surface of the mounting plate has a positioning hole for the lateral threaded hole, and the bolt can be inserted into the positioning hole to restrict the sliding of the limiting sleeve.

[0014] This utility model provides a multi-directional rotating device for a wind tunnel support. It has the following beneficial effects: 1. This multi-directional rotating device for the duct support allows the rotating seat to rotate around the pivot at the end of the mounting plate by rotating the clamp, thereby adjusting the pitch angle of the fan. Before rotating the clamp, the limiting sleeve is pushed away from the rotating seat, thus disengaging the limiting sleeve from the rotating seat. At this time, the rotating seat can rotate freely, thereby adjusting the pitch angle of the clamp. The operation can be completed by pushing the limiting sleeve to slide radially along the mounting plate, simplifying the steps of adjusting the clamp angle. It is easy to use, has a simple structure, and is easy to maintain. By combining the horizontal rotation of the main support with the pitch rotation of the clamp, the position of the fan can be flexibly adjusted and adjusted at multiple angles.

[0015] 2. This multi-directional rotating device for the wind tunnel support uses several thrust grooves on the circumferential surface of the rotating seat. The limiting protrusion on the inner circumferential surface of the limiting sleeve engages with the corresponding thrust groove, thereby limiting the rotation of the rotating seat. The length of the limiting protrusion is less than the depth of the thrust groove. When the limiting sleeve is pushed to slide, the limiting protrusion can be disengaged from the thrust groove, thus unlocking the rotating seat. The engaging structure is stable and can reduce the risk of the rotating seat rotating arbitrarily during the operation of the wind turbine.

[0016] 3. The multi-directional rotation device of the air duct support is achieved by connecting a bolt to the lateral threaded hole. A spring washer is set between the bolt and the limiting sleeve. The end of the bolt is inserted into the positioning hole to achieve complete locking of the limiting sleeve, ensuring the stability of the limiting sleeve locking the rotating seat.

[0019] Multi-directional rotating device for ventilation duct support, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: The main support 10 has a clamp 13 on one side, and a fan is installed on the clamp 13. The main support 10 has adjustment components on its top and side walls for adjusting the horizontal angle of the main support 10 and the pitch angle of the clamp 13, respectively. Each adjustment component includes a mounting plate 12, a rotating seat 20, and a limiting sleeve 21. A mounting plate 12 is fixedly mounted on the side wall of the main support 10. The rotating seat 20 is fixedly connected to the clamp 13 and rotatably connected to the mounting plate 12. The limiting sleeve 21 is elastically connected to the mounting plate 12 and engages with the rotating seat 20. Both the mounting plate 12 and the rotating seat 20 are circular plates. The mounting plate 12 has a welded shaft, and the rotating seat 20 has a shaft hole through which the shaft passes and is limited by a snap ring. The limiting sleeve 21 is annular. The diameter is equal to the outer diameter of the mounting plate 12. The limiting sleeve 21 can slide radially along the circumferential surface of the mounting plate 12. The top of the main support 10 is fixedly mounted with an identical rotating seat 20. The top of the rotating seat 20 is rotatably connected to another mounting plate 12. The mounting plate 12 has a mounting hole for hoisting the entire device onto the building. The rotating seat 20 at the top of the main support 10 has the same thrust groove 22. The circumferential surface of the rotating seat 20 is provided with another limiting sleeve 21 that is elastically connected to the mounting plate 12 to lock the rotation of the rotating seat 20. By the horizontal rotation of the main support 10 and the pitch rotation of the clamp 13, the position of the fan can be flexibly adjusted and adjusted at multiple angles. The clamp 13 is fixed to the rotating seat 20 by welding. By rotating the clamp 13, the rotating seat 20 rotates around the shaft at the end of the mounting plate 12, thereby adjusting the pitch angle of the fan. Before rotating the clamp 13, the limiting sleeve 21 is pushed away from the rotating seat 20, thereby releasing the limiting sleeve 21 from the rotating seat 20. At this time, the rotating seat 20 can rotate freely, thereby adjusting the pitch angle of the clamp 13. The operation can be completed by pushing the limiting sleeve 21 to slide radially along the mounting plate 12, which simplifies the steps of adjusting the angle of the clamp 13. It is easy to use, has a simple structure, and is easy to maintain later.

[0020] like Figure 4 and Figure 5 As shown, the adjustment assembly also includes a thrust groove 22 and a limiting protrusion 23. The limiting sleeve 21 is fixedly installed with the limiting protrusion 23. The rotating seat 20 is provided with several thrust grooves 22. The limiting protrusion 23 can be inserted into the thrust groove 22 to restrict the rotation of the rotating seat 20. The thrust groove 22 is provided on the circumferential surface of the rotating seat 20. The thrust groove 22 is a semi-circular groove. The limiting protrusion 23 is fixedly installed on the inner circumferential surface of the limiting sleeve 21. The limiting protrusion 23 and the thrust groove 22 are in clearance fit. In this scheme, in order to achieve the snap-fit ​​between the limiting sleeve 21 and the rotating seat 20, several thrust grooves 22 are opened on the circumferential surface of the rotating seat 20. The limiting protrusion 23 on the inner circumferential surface of the limiting sleeve 21 is snapped into the corresponding thrust groove 22 to achieve axial limiting of the rotating seat 20 and thus restrict the rotation of the rotating seat 20. The length of the limiting protrusion 23 is less than the depth of the thrust groove 22. When the limiting sleeve 21 is pushed to slide, the limiting protrusion 23 can be disengaged from the thrust groove 22, thus unlocking the rotating seat 20. The snap-fit ​​structure is stable and can reduce the risk of the rotating seat 20 rotating arbitrarily during the operation of the fan.

[0021] like Figure 3 and Figure 5 As shown, the adjustment assembly also includes a spring 24. The spring 24 is fixedly installed on the outer circumference of the limiting sleeve 21. The end of the spring 24 is fixedly installed with the main bracket 10. The spring 24 forms a wave-shaped plate. The spring 24, made of spring steel, provides tension. When the limiting sleeve 21 is pushed away from the rotating seat 20, the spring 24 is deformed by force. After the limiting sleeve 21 is released, the spring 24 returns to its original shape and the limiting sleeve 21 is reset. Then the limiting protrusion 23 is inserted into the thrust groove 22. The structure is simple and the locking effect is stable.

[0022] like Figure 5 As shown, the adjustment assembly also includes a lateral threaded hole 25. The circumferential surface of the limiting sleeve 21 has a lateral threaded hole 25, and a bolt is provided in the lateral threaded hole 25. The circumferential surface of the mounting plate 12 has a positioning hole for the lateral threaded hole 25. The bolt can be inserted into the positioning hole to restrict the sliding of the limiting sleeve 21. In this solution, in order to reduce the probability of the limiting sleeve 21 sliding during the operation of the fan, a bolt is threaded into the lateral threaded hole 25. A spring washer is provided between the bolt and the limiting sleeve 21. The end of the bolt is inserted into the positioning hole to achieve complete locking of the limiting sleeve 21, ensuring the stability of the limiting sleeve 21 locking the rotating seat 20.

[0023] The working principle of this utility model is as follows: Pushing the limiting sleeve 21 away from the rotating seat 20 allows the limiting protrusion 23 to exit from the thrust groove 22, unlocking the rotating seat 20. Rotating the clamp 13 causes the rotating seat 20 to rotate around the shaft at the end of the mounting plate 12, thus adjusting the pitch angle of the fan. A spring 24, made of spring steel, provides tension. When pushing the limiting sleeve 21 away from the rotating seat 20, the spring 24 deforms under force. After releasing the limiting sleeve 21, the spring 24 returns to its original shape, causing the limiting sleeve 21 to reset. The limiting protrusion 23 then engages with the thrust groove 22, and the limiting protrusion on the inner circumferential surface of the limiting sleeve 21... The 23 is inserted into the thrust groove 22 at the corresponding position to achieve axial limiting of the rotating seat 20, thereby restricting the rotation of the rotating seat 20. An identical rotating seat 20 is fixedly installed on the top of the main support 10. The top of the rotating seat 20 is rotatably connected to another mounting plate 12. The mounting plate 12 has mounting holes for hoisting the entire device onto the building. The rotating seat 20 at the top of the main support 10 has the same thrust groove 22. The circumferential surface of the rotating seat 20 is provided with another limiting sleeve 21 that is elastically connected to the mounting plate 12 to lock the rotation of the rotating seat 20. The horizontal angle of the air duct is adjusted by the horizontal rotation of the main support 10.
