Description

Technical Field

[0001] This utility model relates to the field of installation structure technology, specifically to an installation structure for an air conditioning centrifugal fan. Background Technology

[0002] Traditional fixed supports, as a basic support structure that has been widely adopted and tested in the field of wind turbine installation for many years, occupy an important position in the industry's development. They can be quickly built and adjusted according to the actual terrain and wind turbine layout requirements, effectively reducing construction difficulty and cost, and providing a solid and reliable support guarantee for the stable operation of wind turbines.

[0003] In the current technology, with the rapid development of the wind power industry, the iteration cycle of wind turbine equipment has been significantly shortened, and the size parameters of new models of units show a diversified development trend. However, when faced with new wind turbines of different sizes and parameters, traditional mounting brackets have low adaptability. Moreover, traditional mounting brackets are connected to the wall by bolts, which means that during installation, workers must accurately measure and then drill mounting holes in the wall to fix the mounting brackets. This greatly increases the difficulty of the installation work. If there is a deviation in the position of the mounting holes, it will cause the mounting bracket to shift from the mounting hole position of the chassis. If the installation is forced, the chassis will shift at best, and at worst, the chassis will slip during operation due to instability. This seriously affects the progress of the installation work. Utility Model Content

[0004] The purpose of this utility model is to provide an air conditioning centrifugal fan installation structure to solve the problems mentioned in the background art, such as the rapid iteration and diverse sizes of wind turbines in the wind power industry, the low adaptability of their mounting brackets during installation, and the fact that the traditional method of opening mounting holes is used when installing the mounting brackets, which greatly increases the difficulty of installation work once deviation occurs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning centrifugal fan mounting structure, including a main mounting base, an external mounting buckle fixedly connected to the main mounting base, a first adjusting component disposed on the main mounting base, a first mounting base disposed on the first adjusting component, a second mounting base disposed outside the first mounting base, a connecting rod mounted on the first mounting base and the second mounting base, a first bolt threadedly connected to the first mounting base, a second bolt threadedly connected to the second mounting base, a transmission component disposed on the second mounting base, a snap-fit ​​component disposed on the second adjusting component, a chassis bracket mounted on the second adjusting component, and a connecting rod fixedly connected to the second mounting base. The first adjusting component is used to adjust the rotation of the first mounting base, the transmission component is used to adjust the opening and closing of the snap-fit ​​component, and the second adjusting component is used to adjust the position of the chassis bracket.

[0006] In a preferred embodiment of this technical solution, the second adjustment component includes a mounting bracket mounted on a second mounting base, a first threaded rod rotatably connected to the mounting bracket, a first knob fixedly connected to the first threaded rod, a sliding seat threadedly connected to the first threaded rod, a third bolt disposed between the chassis bracket and the sliding seat, and a nut threadedly connected to the third bolt. The sliding seat is slidably connected to the mounting bracket, and the chassis bracket is mounted on the sliding seat. The first knob is used to adjust the rotation of the first threaded rod, which in turn drives the sliding seat to slide. The third bolt and nut work together to restrict the installation of the chassis bracket.

[0007] In the preferred embodiment of this technical solution, the mounting bracket has a matching groove at the relative position of the sliding seat, and the sliding seat is slidably connected to the groove.

[0008] In a preferred embodiment of this technical solution, the transmission assembly includes a second threaded rod threadedly connected to a second mounting base, a second knob fixedly connected to the second threaded rod, a sliding plate slidably connected to the second mounting base, a sliding block slidably connected to the sliding plate, and a first spring fixedly connected between the sliding plate and the second mounting base. The second knob is rotatably connected to the sliding plate and is used to adjust the rotation of the second threaded rod, thereby driving the sliding plate to slide.

[0009] In a preferred embodiment of this technical solution, the sliding plate has a matching groove at the relative position of the second threaded rod, and the second threaded rod is rotatably connected to the sliding plate.

[0010] In a preferred embodiment of this technical solution, the sliding block has a groove adapted to the sliding plate, and the sliding block is slidably connected to the sliding plate through the groove.

[0011] According to the preferred embodiment of this technical solution, the snap-fit ​​assembly includes a connecting plate fixedly mounted on the sliding block, a second spring fixedly connected between the connecting plate and the second mounting base, and a snap-fit ​​block fixedly connected to the connecting plate. The connecting plate is slidably connected to the second mounting base, and the snap-fit ​​block is snap-fitted to the mounting bracket. The sliding plate and the sliding block cooperate to drive the connecting plate to move, thereby controlling the snap-fit ​​block to release or restore the snap-fit ​​to the mounting bracket.

[0012] In a preferred embodiment of this technical solution, the first adjustment component includes a worm gear rotatably connected to the main mounting base, a third knob fixedly connected to the worm gear, and a worm wheel meshing with the worm gear. The worm wheel is rotatably connected to the main mounting base, and the first mounting base is fixedly mounted on the worm wheel. The third knob is used to adjust the rotation of the worm gear, and the rotation of the first mounting base is adjusted by the cooperation between the worm gear and the worm wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The second mounting bracket adopts a modular design. During installation, the required number of second mounting brackets are installed according to the different sizes of the chassis. The second adjustment component is then installed on the chassis bracket at the required position, which greatly increases the adaptability of the single bracket and fully adapts to different chassis sizes. The distance between the two sets of chassis brackets can be changed by adjusting the second adjustment component. The two work together to greatly improve the portability and work efficiency of the installation work.

[0014] 2. After the main mounting base is installed, the first mounting base can be rotated by adjusting the first adjustment component, thereby adjusting the horizontal state of the first mounting base and the installed second mounting base. This avoids the problem that the first mounting base may tilt due to installation misalignment, requiring the main mounting base to be disassembled and reinstalled in order to adjust the level of the first mounting base, thus further improving the convenience of the installation work.

[0015] 3. By setting up transmission components and snap-fit ​​components, compared with the cumbersome process of "tightening a large number of bolts → cutting deformed structures → separating parts" when disassembling traditional fixed brackets, this design compresses the disassembly steps to "turning a knob → unlocking the snap-fit". Even non-professional installers can complete the process quickly, greatly reducing the difficulty of operation and significantly improving the efficiency of later equipment maintenance and replacement.

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.

[0019] Please see Figure 1 - Figure 7This utility model provides an embodiment of an air conditioner centrifugal fan installation structure, including a main mounting base 1, an external mounting buckle 4 fixedly connected to the main mounting base 1, a first adjusting component disposed on the main mounting base 1, a first mounting base 21 disposed on the first adjusting component, a second mounting base 22 disposed outside the first mounting base 21, a connecting rod 23 mounted on the first mounting base 21 and the second mounting base 22, a first bolt 24 threadedly connected to the first mounting base 21, a second bolt 25 threadedly connected to the second mounting base 22, a transmission component disposed on the second mounting base 22, a snap-fit ​​component disposed on the second adjusting component, a chassis bracket 26 mounted on the second adjusting component, and the connecting rod 23 fixedly connected to the second mounting base 22. The first adjusting component is used to adjust the rotation of the first mounting base 21, the transmission component is used to adjust the opening and closing of the snap-fit ​​component, and the second adjusting component is used to adjust the position of the chassis bracket 26. The main mounting base 1 is secured by the external mounting buckle 4 and the external fastening bolt. After mounting base 1 is installed on the wall, adjust the horizontal state of the first mounting base 21 by adjusting the first adjustment component according to the inclination of the first mounting base 21. Then, according to the required external size, install the required number of second mounting bases 22 on the first mounting base 21. After installing the connecting rod 23 on the first set of second mounting bases 22 onto the first mounting base 21, install the first bolt 24 onto the first mounting base 21 to complete the assembly of the first set of second mounting bases 22. Then, install the connecting rod 23 connected to the second set of second mounting bases 22 onto the first set of second mounting bases 22, and install the second bolt 25 onto the second mounting base 22 to complete the installation of the second set of second mounting bases 22. Install the required number of second mounting bases 22 as needed. Then, install the second adjustment component and the chassis bracket 26 onto the second mounting bases 22 in the required positions. Adjust the second adjustment component according to the different chassis mounting hole positions to flexibly adjust the distance between the two sets of chassis brackets 26. Finally, install the chassis onto the chassis bracket 26 to complete the installation work.

[0020] Please see Figure 1 - Figure 4A further embodiment of this solution is as follows: the second adjustment component includes a mounting bracket 27 mounted on the second mounting base 22, a first threaded rod 28 rotatably connected to the mounting bracket 27, a first knob 29 fixedly connected to the first threaded rod 28, a sliding seat 210 threadedly connected to the first threaded rod 28, a third bolt 212 disposed between the chassis bracket 26 and the sliding seat 210, and a nut 213 threadedly connected to the third bolt 212. The sliding seat 210 is slidably connected to the mounting bracket 27, and the chassis bracket 26 is mounted on the sliding seat 210. On the movable base 210, the first knob 29 is used to adjust the rotation of the first threaded rod 28. The rotation of the first threaded rod 28 drives the sliding base 210 to slide. The installation of the chassis bracket 26 is restricted by the cooperation of the third bolt 212 and nut 213. The position adjustment of the sliding base 210 is achieved by the cooperation of the threaded rod and the knob. The installation position can be flexibly adjusted according to the chassis size requirements. With the locking structure of the bolt and nut 213, the convenience of adjustment is ensured, and a stable connection is formed after adjustment, so as to prevent the chassis from shifting or shaking during use.

[0021] Please see Figure 1 , Figure 3 A further solution based on this embodiment is as follows: the mounting bracket 27 has a matching groove at the relative position of the sliding seat 210, the sliding seat 210 is slidably connected to the groove, the groove structure provides guiding constraints for the sliding seat 210, ensuring that the sliding seat 210 moves smoothly along the preset trajectory during the adjustment process, avoiding deviation or jamming, while enhancing the integrity of the connection between the sliding seat 210 and the mounting bracket 27, and improving the load-bearing capacity and stability of the adjustment mechanism.

[0022] Please see Figure 1 , Figure 5 A further embodiment of this solution is as follows: the transmission assembly includes a second threaded rod 214 threadedly connected to the second mounting base 22, a second knob 215 fixedly connected to the second threaded rod 214, a sliding plate 216 slidably connected to the second mounting base 22, a sliding block 217 slidably connected to the sliding plate 216, and a first spring 218 fixedly connected between the sliding plate 216 and the second mounting base 22. The second knob 215 is rotatably connected to the sliding plate 216 and is used to adjust the rotation of the second threaded rod 214. The rotation of the second threaded rod 214 drives the sliding plate 216 to slide. The threaded rod transmission realizes precise displacement control of the sliding plate 216. With the elastic reset function of the first spring 218, the mechanism can automatically maintain a stable state after adjustment. At the same time, the combination structure of the sliding plate 216 and the sliding block 217 provides a flexible transmission basis for the linkage of the subsequent snap-fit ​​components, taking into account both adjustment accuracy and ease of operation.

[0023] Please see Figure 1 , Figure 5A further solution based on this embodiment is as follows: the sliding plate 216 has a matching groove at the relative position of the second threaded rod 214. The second threaded rod 214 is rotatably connected to the sliding plate 216. The groove structure realizes the rotational connection between the second threaded rod 214 and the sliding plate 216, which not only ensures the smoothness of the threaded rod rotation, but also converts the rotational motion of the threaded rod into the linear motion of the sliding plate 216, reduces the frictional resistance in the transmission process, and improves the feel of the adjustment operation and the service life of the mechanism.

[0024] Please see Figure 1 , Figure 5 A further solution based on this embodiment is as follows: a groove adapted to the sliding plate 216 is provided on the sliding block 217. The sliding block 217 is slidably connected to the sliding plate 216 through the groove. The groove matching structure enables the sliding block 217 to slide stably along the sliding plate 216, providing precise motion guidance for the sliding block 217 and ensuring that the sliding block 217 maintains a reliable connection with the sliding plate 216 during the transmission process.

[0025] Please see Figure 5 - Figure 6 A further solution based on this embodiment is as follows: The snap-fit ​​assembly includes a connecting plate 219 fixedly mounted on the sliding block 217, a second spring 220 fixedly connected between the connecting plate 219 and the second mounting base 22, and a snap-fit ​​block 221 fixedly connected to the connecting plate 219. The connecting plate 219 is slidably connected to the second mounting base 22, and the snap-fit ​​block 221 is snap-fitted to the mounting bracket 27. The sliding plate 216 and the sliding block 217 cooperate to drive the connecting plate 219 to move, thereby controlling the snap-fit ​​block 221 to release or restore the snap-fit ​​to the mounting bracket 27. The snap-fit ​​cooperation between the snap-fit ​​block 221 and the mounting bracket 27 can quickly achieve the positioning and fixation of the mounting bracket 27. With the elastic force of the second spring 220, the stability of the snap-fit ​​state can be maintained when there is no external force adjustment. The linkage control of the sliding plate 216 and the sliding block 217 controls the release and restoration of the snap-fit, which is convenient to operate and can quickly complete the disassembly and fixing of the mounting bracket 27, improving the efficiency of equipment maintenance and adjustment.

[0026] Please see Figure 1 , Figure 7A further solution based on this embodiment is as follows: The first adjustment component includes a worm gear 31 rotatably connected to the main mounting base 1, a third knob 33 fixedly connected to the worm gear 31, and a worm wheel 32 meshing with the worm gear 31. The worm wheel 32 is rotatably connected to the main mounting base 1, and the first mounting base 21 is fixedly mounted on the worm wheel 32. The third knob 33 is used to adjust the rotation of the worm gear 31. Through the cooperation of the worm gear 31 and the worm wheel 32, the rotation of the first mounting base 21 is adjusted. The worm gear 31 and worm wheel 32 transmission has a self-locking characteristic, which can make the first mounting base 21 stably positioned at any rotation angle and avoid angle deviation due to external force. The angle adjustment of the first mounting base 21 is realized by the knob operation. The transmission ratio is stable and the adjustment accuracy is high, which can meet the fine requirements of the installation angle in different scenarios. In use, the horizontal state of the first mounting base 21 and its connected components can be adjusted according to the situation to avoid affecting the installation of the chassis bracket 26 and the subsequent chassis due to the tilting of the main mounting base 1.

[0027] Working principle: By cooperating with the external fastener 4 and the external bolts, the main mounting base 1 is fixedly installed to the wall, completing the basic structural fixation. Then, the tilt status of the first mounting base 21 is observed. If tilting exists, it needs to be leveled using the first adjustment component. By operating the third knob 33, the worm gear 31, which is fixedly connected to the third knob 33, rotates on the main mounting base 1. Because the worm gear 31 meshes with the worm wheel 32, the rotation of the worm gear 31 drives the worm wheel 32 to rotate synchronously on the main mounting base 1. Since the first mounting base 21 is fixed to the worm wheel 32, the rotation of the worm wheel 32 directly drives the first mounting base 21 to rotate. Rotate mounting base 21 until it is adjusted to a horizontal position. Determine the number of second mounting bases 22 to be installed according to the external equipment to be installed. When installing the first set of second mounting bases 22, fix its connecting rod 23 to the first mounting base 21, and then thread the first bolt 24 to the first mounting base 21. Secure the connection between the connecting rod 23 and the first mounting base 21 by tightening the bolt, thus completing the assembly of the first set of second mounting bases 22. When installing subsequent second mounting bases 22, fix its connecting rod 23 to the previous set of second mounting bases 22, and then thread the second bolt 25 to the current set of second mounting bases 22. The second mounting base 22 is secured to the connecting rod 23 by the locking action of the second bolt 25, thus expanding the number of second mounting bases 22 as needed. After the second mounting bases 22 are installed, the second adjustment component and the chassis bracket 26 are installed on the second mounting base 22 at the target position. According to the mounting hole requirements of different chassis, the first threaded rod 28 is rotated on the mounting bracket 27 by operating the first knob 29. Because the sliding seat 210 is threadedly connected to the first threaded rod 28 and slidably connected to the mounting bracket 27, the first threaded rod... The rotation of 28 is converted into the linear sliding of the sliding seat 210 along the mounting bracket 27; while the chassis bracket 26 is mounted on the sliding seat 210. The sliding of the sliding seat 210 directly drives the chassis bracket 26 to move synchronously until it is adjusted to a position that matches the mounting hole of the chassis. The third bolt 212 passes through the chassis bracket 26 and the sliding seat 210, and then the nut 213 is threaded to the third bolt 212. The locking fit of the bolt and the nut 213 restricts the relative position of the chassis bracket 26 and the sliding seat 210, ensuring that the chassis bracket 26 is firmly fixed and preventing displacement or shaking during subsequent use. When it is necessary to disassemble the chassis bracket 26 from the chassis, the second knob 215 is operated to drive the second threaded rod 214, which is fixedly connected to the second knob 215, to rotate on the second mounting base 22. Since the second threaded rod 214 is rotatably connected to the sliding plate 216, its rotation will drive the sliding plate 216 to slide on the second mounting base 22. When the sliding plate 216 slides, it drives the sliding block 217, which is slidably connected to it, to move synchronously. The sliding block 217 is fixedly connected to the connecting plate 219. The movement of the sliding block 217 drives the connecting plate 219 to slide on the second mounting base 22, which in turn drives the snap-fit ​​block 221, which is fixed to the connecting plate 219, to move, so that the snap-fit ​​block 221 is disengaged from the mounting bracket 27, thereby unlocking the mounting bracket 27 and removing the mounting bracket 27 and the connected chassis bracket 26 and the installed chassis.
