[0035] See also Figure 1 and Figure 2 The base 100 of the embodiment of the utility model is used for an air conditioning unit 1000, which includes a fan 200 and a motor 300, which are connected by a belt 400. The base 100 includes a bracket 10 and an adjusting device 20. The bracket 10 is used to install the fan 200 and the motor 300; the adjusting device 20 includes a rotating member 21 and a moving member 22 connected to the rotating member 21, the rotating member 21 is installed on the bracket 10, and the moving member 22 is used to install the motor 300. The rotating member 21 rotates to drive the moving member 22 to move, and the moving member 22 can drive the motor 300 to move closer to or away from the fan 200 to adjust the tension of the belt 400.

[0036] In the base 100 of the embodiment of the present invention, by conveniently and quickly rotating the rotating member 21 to drive the movement of the moving member 22, the motor 300 can be close to or away from the fan 200, thereby adjusting the tension of the belt 400. This adjustment method simplifies the installation process, improves the installation efficiency, and has a large adjustment range, which can adapt to motors 300 of different structures and sizes.

[0037] Specifically, the air conditioning unit 1000 includes core components such as a fan 200 and a motor 300, and is the main device for realizing the air conditioning function. The air conditioning unit 1000 can be subdivided into household air conditioning units, commercial air conditioning units, industrial air conditioning units, etc. according to its use and specifications. The base 100 is the basic structure for the installation of the entire air conditioning unit 1000, which carries and fixes the fan 200 and the motor 300 to ensure their stable operation.

[0038] The fan 200 is responsible for the circulation of air, and the motor 300 provides the power for the fan 200 to rotate. The two are connected by a belt 400 to achieve power transmission. The fan 200 can be divided into a centrifugal fan, an axial flow fan, etc. according to the airflow direction; the motor 300 can be selected according to parameters such as power and speed.

[0039] The belt 400 is a transmission component that connects the fan 200 and the motor 300, and realizes the transmission of the power of the motor 300 to the fan 200. The material, width, length and other parameters of the belt 400 need to be selected and adjusted according to the actual specifications of the fan 200 and the motor 300 to ensure the efficiency and stability of the transmission. The tension of the belt 400 will affect the efficiency and stability of the transmission, so the tension of the belt 400 needs to be adjusted during the installation process.

[0040] The adjusting device 20 includes a rotating member 21 and a moving member 22, which are used to adjust the distance between the motor 300 and the fan 200, so as to adjust the tension of the belt 400. The rotating member 21 is a part of the adjusting device 20, and drives the moving member 22 to move by rotating. The rotating member 21 can be a part that is easy to operate manually, such as a bolt or a knob, or a rotating mechanism driven by the motor 300 to achieve automatic adjustment.

[0041] The moving member 22 is connected to the rotating member 21, and is moved by the driving of the rotating member 21, thereby driving the motor 300 to adjust the position. The moving member 22 can be fixedly connected to the motor 300, so that the motor 300 moves with the moving member 22. By rotating the moving member 22 by the rotating member 21, the driving of the moving member 22 can be conveniently and quickly realized, and by adjusting the rotation angle of the rotating member 21, a larger adjustment range can be obtained.

[0042] See also Figure 2 and Figure 3 In some embodiments, the moving part 22 includes a first connecting part 220 and a second connecting part 221 connected to the first connecting part 220, the first connecting part 220 is bent relative to the second connecting part 221, the first connecting part 220 is sleeved on the rotating part 21, and the second connecting part 221 is used to install the motor 300.

[0043] In this way, the first connection part 220 is bent relative to the second connection part 221, which makes the moving member 22 more flexible in structure and can adapt to more installation environments and adjustment requirements with lower material loss. At the same time, the first connection part 220 is sleeved on the rotating member 21, and this structure enables the rotating member 21 to stably drive the moving member 22 to move.

[0044] Specifically, the bending angle and bending mode of the first connection portion 220 can be designed according to actual needs, such as using different bending modes such as arc and folded line to ensure that it can adapt to different installation environments and space restrictions. For example, the angle between the first connection portion 220 and the second connection portion 221 can be 90°.

[0045] The first connection part 220 and the second connection part 221 can both be metal plates or metal blocks with a certain thickness, such as plates made of angle iron. The first connection part 220 can be provided with a through hole for the rotating member 21 to pass through, and the second connection part 221 can be provided with a mounting point for the power supply machine 300 to be installed. The first connection part 220 and the second connection part 221 can be integrally formed or separately formed. The first connection part 220 can move with the rotation of the rotating member 21. In one embodiment, the rotating member 21 can be a rod with a thread, and the rotating member 21 can be rotated manually or automatically; the first connection part 220 can be a sliding sleeve, which has a thread groove inside that matches the thread of the rotating member 21, and is sleeved on the rotating member 21. When the rotating member 21 rotates, due to the meshing action of the thread, the first connection part 220 will move along a certain direction.

[0046] See also Figure 2 and Figure 3 In some embodiments, the moving member 22 further includes a first nut 222 disposed on the first connecting portion 220 , and the rotating member 21 includes a first bolt 210 , and the first bolt 210 is passed through the first connecting portion 220 and the first nut 222 .

[0047] In this way, the moving distance and speed of the moving member 22 can be precisely controlled by the cooperation of the first bolt 210 and the first nut 222. When the first bolt 210 is rotated, the first nut 222 will rotate accordingly, thereby driving the entire moving member 22 to move. Since the cooperation of the bolt and the nut has high precision and stability, more precise adjustment can be achieved to meet different installation requirements.

[0048] In addition, the stability and reliability of the adjustment process of the first bolt 210 and the first nut 222 are high. The structure of the first bolt 210 and the first nut 222 itself has strong bearing capacity and vibration resistance, and can maintain a good working state even in a harsh working environment.

[0049] The first nut 222 can be welded to the first connection part 220, and the first connection part 220 can be connected to the threaded hole of the first bolt 210, and the threaded hole can correspond to the position of the first nut 222. The type and specification of the first nut 222 can be selected according to actual conditions, such as an external hexagonal welding nut, a round nut, etc. The type and specification of the first bolt 210 can be selected according to actual conditions, such as a full-thread external hexagonal bolt, etc.

[0050] In the related art, in order to make the belt 400 reach the appropriate tension, two guide rails for adjusting the motor 300 can be installed on the bracket 10, and the motor 300 can be pushed forward and backward on the guide rail slide by the push rod to achieve the purpose of adjusting the tension of the belt 400. This method requires the customization of the guide rail of appropriate length according to the size of the motor 300, which will increase the manufacturing cost of the equipment in actual application. In the embodiment of the utility model, the first bolt 210 and the first nut 222 are matched to realize the rotation member 21 to drive the moving member 22 to move, and there is no need to customize the guide rail. Therefore, this method of the embodiment of the utility model has a wide range of application and low manufacturing cost.

[0051] See also Figure 2 and Figure 4 In some embodiments, the bracket 10 is provided with a first mounting hole 11, the rotating member 21 also includes a limiting component 211, the first bolt 210 is passed through the first mounting hole 11 and the limiting component 211, and the bracket 10 is located between the head of the first bolt 210 and the limiting component 211.

[0052] In this way, the limiting component 211 can limit the position of the first bolt 210, effectively reducing the risk of the first bolt 210 accidentally detaching from the first mounting hole 11 during the adjustment of the first bolt 210, thereby improving the safety and reliability of the adjustment process. In addition, during the adjustment process, due to the presence of the limiting component 211, the swing of the first bolt 210 can be effectively controlled, avoiding the problem of inaccurate adjustment or damage to the mechanical structure caused by the swing, thereby improving the accuracy and stability of the adjustment and extending the service life of the base 100.

[0053] Specifically, the first mounting hole 11 is a through hole provided on the bracket 10 for passing the first bolt 210. The first mounting hole 11 may be a threaded hole, and the aperture and thread of the first mounting hole 11 may match the first bolt 210. The limiting component 211 may be a baffle or a locking member with threads. For example, the limiting component 211 may be a limiting circular gasket. The limiting component 211 may be welded to the first bolt 210 after the first bolt 210 passes through the first mounting hole 11. During the process of rotating the first bolt 210, the limiting component 211 may fit with the bracket 10, thereby limiting the maximum position of the axial movement of the first bolt 210 toward the first mounting hole 11, reducing the risk of the first bolt 210 detaching from the first mounting hole 11, and reducing the degree of swinging of the first bolt 210.

[0054] See also Figure 2 and Figure 5 In some embodiments, the bracket 10 is provided with a through slot 12 , and the base 100 includes a first connecting component 30 , which is passed through the moving member 22 and the through slot 12 and is used to connect with the motor 300 .

[0055] In this way, the through slot 12 can provide a moving path for the first connecting component 30 and can limit the moving range of the first connecting component 30 , which improves the moving stability of the motor 300 .

[0056] Specifically, through slot 12 is the slot provided on support 10, for allowing first connecting assembly 30 to pass. Through slot 12 can correspond to the hole position provided on moving member 22. First connecting assembly 30 can be bolt, nut or other fasteners, to ensure the firmness of connection and to be convenient for the disassembly and assembly of motor 300 and moving member 22. Due to the connection relationship between moving member 22, first connecting assembly 30 and motor 300, therefore moving member 22 can drive first connecting assembly 30 and motor 300 to move in the process of moving. Through slot 12 can limit the moving direction of moving member 22, for example, through slot 12 can extend along the direction of motor 300 towards blower fan 200, and the moving direction of moving member 22 is the direction of motor 300 towards or away from blower fan 200, and now motor 300 can move towards or away from blower fan 200.

[0057] See also Figure 2 In some embodiments, the first connecting assembly 30 includes a second nut 31 and a second bolt 32, the second bolt 32 is passed through the moving part 22 and the through slot 12 and is used to connect with the motor 300, and the second nut 31 is sleeved on the second bolt 32 and is used to fix the motor 300.

[0058] Thus, the second nut 31 and the second bolt 32 cooperate to make the installation and removal of the motor 300 more convenient and quick, and the motor 300 can be stably fixed on the base 100, and help reduce the vibration and noise generated during the operation of the motor 300. In addition, the second bolt 32 can connect the moving member 22 and the motor 300, so that the motor 300 can move with the moving member 22.

[0059] Specifically, the second nut 31 and the second bolt 32 can be used to fix the mounting foot of the motor 300, and the mounting foot of the motor 300 can be provided with corresponding holes or threads. The second bolt 32 is used to pass through the moving part 22 and the through slot 12, and is connected to the corresponding hole or thread on the mounting foot of the motor 300. The second nut 31 is sleeved on the second bolt 32, and the second bolt 32 is tightened by rotating the second nut 31, thereby fixing the motor 300. The head of the second bolt 32 can be selected into different shapes such as a hexagonal head and a round head as needed to facilitate installation and disassembly. For example, the second bolt 32 can be a full-thread external hexagon bolt. The internal thread of the second nut 31 matches the external thread of the second bolt 32 to ensure that it can be tightly engaged during rotation to prevent loosening. The type and specification of the second nut 31 can be selected according to actual needs, such as an external hexagonal welding nut, a round nut, etc.

[0060] See also Figure 5 and Figure 6 In some embodiments, the through groove 12 includes a first groove 120 and a second groove 121 spaced apart from the first groove 120 , the second groove 121 is arranged opposite to the moving part 22 , the second bolt 32 is passed through the moving part 22 and the first groove 120 and is used to connect with the motor 300 , and the second groove 121 is used to install the motor 300 .

[0061] In this way, the first groove 120 and the second groove 121 are arranged at intervals to reduce the length of the groove on the base 100, thereby reducing the adverse effect of the operation of opening the groove body on the structural strength of the base 100. The first groove 120 can provide a moving path for the motor 300 and can limit the position of the motor 300. At the same time, the arrangement of the first groove 120 can facilitate the connection between the moving member 22 and the motor 300.

[0062] Specifically, the first groove 120 can be used as a passage for the second bolt 32 to pass through, forming a connection with the moving member 22 and the motor 300. The second groove 121 can provide additional fixing support for the motor 300. The size and shape of the first groove 120 and the second groove 121 can be the same or different. The extension direction of the first groove 120 and the second groove 121 can be the same, so as to facilitate the installation of the motor 300.

[0063] See also Figure 1 and Figure 7 In some embodiments, the base 100 also includes a second connecting assembly 40, the second connecting assembly 40 includes a third nut 41 and a third bolt 42, the third bolt 42 is passed through the second groove 121 and is used to connect to the motor 300, and the third nut 41 is sleeved on the third bolt 42 and is used to fix the motor 300.

[0064] In this way, the third nut 41 and the third bolt 42 cooperate to make the installation and removal of the motor 300 more convenient and quick, and the motor 300 can be stably fixed on the base 100, and it helps to reduce the vibration and noise generated by the motor 300 during operation. At the same time, the second nut 31, the second bolt 32, the third nut 41 and the third bolt 42 cooperate together to enable the motor 300 to be firmly fixed on the bracket 10.

[0065] Specifically, the second connection assembly 40 is used to connect with the motor 300 by penetrating the second groove 121, providing additional fixing support for the motor 300. The second connection assembly 40 may include a third nut 41, a third bolt 42 and other corresponding connection components, such as a gasket. The third nut 41 and the third bolt 42 can be used to fix the mounting foot of the motor 300, and the mounting foot of the motor 300 may be provided with a corresponding hole or thread. The third bolt 42 is used to pass through the second groove 121 and connect with the corresponding hole or thread on the mounting foot of the motor 300. The third nut 41 is sleeved on the third bolt 42, and the third bolt 42 is tightened by rotating the third nut 41 to fix the motor 300. The head of the third bolt 42 can be selected from different shapes such as a hexagonal head and a round head as needed to facilitate installation and disassembly. For example, the third bolt 42 can be a full-thread external hexagonal bolt. The internal thread of the third nut 41 matches the external thread of the third bolt 42 to ensure that it can be tightly engaged during rotation to prevent loosening. The type and specification of the third nut 41 can be selected according to actual conditions, such as an external hexagonal welding nut, a round nut, etc.

[0066] See also Figure 5 and Figure 6 In some embodiments, the bracket 10 includes a first cross beam 13 and a second cross beam 14 spaced apart from the first cross beam 13 , the first cross beam 13 and the second cross beam 14 are both provided with a second mounting hole 15 for mounting the fan 200 , the first end 130 of the first cross beam 13 is connected to the first longitudinal beam 16 , the first end 140 of the second cross beam 14 is connected to the second longitudinal beam 17 , two third cross beams 18 spaced apart are provided between the first longitudinal beam 16 and the second longitudinal beam 17 , and the third cross beam 18 is used for mounting the motor 300 .

[0067] In this way, the first cross beam 13 , the second cross beam 14 , the first longitudinal beam 16 , the second longitudinal beam 17 and the third cross beam 18 work together to form a stable support frame, providing a reliable installation foundation for the fan 200 and the motor 300 .

[0068] Specifically, the first crossbeam 13 and the second crossbeam 14 can be arranged in parallel to facilitate the installation of the fan 200. The material of the first crossbeam 13 and the second crossbeam 14 can be selected from high-strength, corrosion-resistant metal materials, such as angle steel or aluminum alloy, to ensure its stability and reliability in long-term use. In addition, the length, cross-sectional shape, and position of the second mounting hole 15 of the first crossbeam 13 and the second crossbeam 14 can be customized according to actual needs to meet the requirements of different fan 200 models and installation environments. The length of the first crossbeam 13 can be longer than the second crossbeam 14. The first end 130 of the first crossbeam 13 and the first end 140 of the second crossbeam 14 can both be an end away from the fan 200, which makes the first longitudinal beam 16 and the second longitudinal beam 17 away from the fan 200, so that the third crossbeam 18 is away from the fan 200, and then the installation space of the motor 300 is larger.

[0069] The first longitudinal beam 16 and the second longitudinal beam 17 can be connecting beams between the first cross beam 13, the second cross beam 14 and the third cross beam 18, and form a frame structure with the above cross beams, so that the overall structural strength of the bracket 10 is enhanced, so that the bracket 10 can withstand a larger load.
