[0002] Computer room air conditioners can provide reliable working temperature and humidity for computer rooms, and can also purify the air in the computer rooms. They are a common type of air conditioning equipment. Most computer room air conditioners are of the bottom air outlet type. When the bottom air outlet type air conditioner is operating, the fan needs to be sunk into the static pressure box under the floor. When maintaining the fan, the fan needs to be lifted from under the floor to the ground and then taken out of the unit.

[0003] In order to achieve the above functions, the traditional method is to manually lift and sink the fan. Since the fan is heavy, multiple people are required to cooperate to complete the lifting and lowering of the fan each time, which not only wastes labor costs, but also makes it impossible to simply and flexibly pause the operation during the process of lifting and lowering the fan. If the fan tips over or the operator is exhausted, corresponding adjustments cannot be made, posing a safety hazard. Summary of the Invention

[0048] Embodiment 1

[0049] This embodiment provides a lifting structure, as Figures 1 - 18As shown, the lifting structure is used to lift and lower the device 1 to be lifted. The device to be lifted includes a bottom plate 12 and a top plate 13 connected by a column 11. Between the bottom plate 12 and the top plate 13 is the body 14 to be lifted. The lifting structure includes a base 2 and a rotating assembly 3. The device 1 to be lifted is located on the base 2. One end of the rotating assembly 3 is connected to the base 2, and the other end of the rotating assembly 3 is connected to the top plate 13. The base 2 has a through hole 21. The rotating assembly 3 rotates to enable the device 1 to be lifted to pass through the through hole 21 to achieve lifting and lowering.

[0050] Specifically, the device 1 to be lifted in this embodiment can be a fan or other heavy objects. In order to lift and lower heavy objects, a bottom plate 12 and a top plate 13 need to be provided. The bottom plate 12 and the top plate 13 are connected by a column 11. The bottom plate 12 and the top plate 13 are horizontally arranged up and down. A heavy object, that is, the body 14 to be lifted, is placed in the cavity between them. In the specific implementation process, the area of the top plate 13 is larger than that of the bottom plate 12, so that when the bottom plate 12 and the top plate 13 are horizontally opposite to each other up and down, the part extending from the outer position of the top plate 13 can avoid the bottom plate 12 and be connected to the base 2.

[0051] When it is necessary to lower the device 1 to be lifted, turn the rotating assembly 3 along the first direction. The device 1 to be lifted slowly sinks under the action of gravity and rotational force. At the same time, the base 2 and the top plate 13 slowly approach each other to achieve the lowering of the device 1 to be lifted, as Figure 2 shown; when it is necessary to lift the device 1 to be lifted, turn the rotating assembly 3 along the second direction. The rotating assembly 3 will slowly lift the device 1 to be lifted. At the same time, the base 2 and the top plate 13 slowly separate from each other to achieve the lifting of the device 1 to be lifted, as Figure 1 shown; among them, the first direction and the second direction are opposite. That is to say, the lifting structure provided in this embodiment changes the traditional method that requires multiple people to achieve lifting and lowering to a method that can be completed by a single person. The lifting process is simple and convenient, saving labor costs, and avoiding safety accidents during the lifting process by manpower, making the operation safer, more reliable and efficient.

[0052] In a specific embodiment, as Figure 1 shown, the lifting structure further includes a fixing component 4. When the device 1 to be lifted is in the lifted state, the fixing component 4 can fix the device 1 to be lifted on the base 2.

[0053] To increase the reliability in the lifting state, a fixing component 4 is added. The fixing component 4 includes two fixing plates, and each fixing plate has a first surface fixedly connected to the base 2 and a second surface fixedly connected to the bottom plate 12. More specifically, the fixing component 4 includes a first fixing plate and a second fixing plate. The first fixing plate includes at least two surfaces. One surface (the first surface) is fixed to the base 2 by screws, and the other surface (the second surface) is fixed to the front side of the bottom plate 12 by screws. The second fixing plate includes at least two surfaces. One surface (the first surface) is fixed to the base 2 by screws, and the other surface (the second surface) is fixed to the rear side of the bottom plate 12 by screws. In this way, the device 1 to be lifted and lowered is fixed in the lifting state by the front and rear fixing plates.

[0054] In addition, to make the fixing plate have higher reliability, after one side of the first surface is perpendicularly connected to one side of the second surface, fixing parts are added at both ends, and the fixing parts make the connection between the first surface and the second surface more reliable.

[0055] When it is necessary to lower the device 1 to be lifted and lowered, first remove the fixing component 4, and then turn the rotating component 3. After completion of lowering, fix the top plate 13 to the base 2 by bolts. When it is necessary to lift the device 1 to be lifted and lowered, first remove the bolts for fixing the top plate 13 and the base 2, and then turn the rotating component 3 in the reverse direction. After completion of lifting, fix the base 2 and the bottom plate 12 together by the fixing component 4.

[0056] In a specific embodiment, as Figures 2 - 4 shown, the rotating component 3 includes a screw rod 31, a first connecting part 32 and a second connecting part 33. One end of the screw rod 31 is matched with the first connecting part 32, and the other end of the screw rod 31 is matched with the second connecting part 33. The first connecting part 32 is located inside the base 2, and the second connecting part 33 is located inside the top plate 13; or the first connecting part 32 is located inside the top plate 13, and the second connecting part 33 is located inside the base 2. In this embodiment, to realize the cooperation between the screw rod 31 and the base 2 and the top plate 13, the first connecting part 32 and the second connecting part 33 are added.

[0057] In a specific embodiment, the first connecting part 32 is a nut, the second connecting part 33 is a bearing, one end of the screw rod 31 is matched with the nut, and the other end of the screw rod 31 is matched with the bearing.

[0058] Regarding the specific installation positions of the nut and the bearing, there are various different choices, specifically:

[0059] The first type, as Figures 1 - 9As shown, the first connecting portion 32 is located within the base 2, the second connecting portion 33 is located within the top plate 13, and the nut is located within the base 2, and the bearing is located within the top plate 13; in this setting, as Figure 2 and Figure 5 shown, a convex boss 131 is provided within the top plate 13, and the bearing is located within the convex boss 131; and H1 > H2 + H3, where H1 is the height of the convex boss 131, H2 is the height of the bearing, and H3 is the height by which the nut protrudes above the upper surface of the base 2.

[0060] The convex boss 131 is used to fix the bearing. The height of the convex boss 131 needs to be greater than the sum of the height of the bearing and the height by which the nut riveted on the base 2 protrudes above the upper surface of the base 2, so that after the device 1 to be lifted and lowered sinks, the top plate 13 and the base 2 can fit together for sealing to prevent air leakage; in addition, the central part of the convex boss 131 is a through hole, and the diameter of the through hole is smaller than the outer diameter of the bearing, so that the bearing cannot pass upward through the convex boss 131, and the screw rod 31 can pass through the through hole of the convex boss 131. In addition, the convex boss 131 is a necked-down structure for preventing the bearing from passing out of the convex boss 131, and the convex boss 131 and the bearing are in interference fit.

[0061] In addition, as Figure 6 shown, the screw rod 31 has a smooth section 311 and a threaded section 312. The smooth section 311 passes through the bearing, and the threaded section 312 cooperates with the nut; a convex platform 313 is provided at the connection between the smooth section 311 and the threaded section 312, and the outer diameter of the convex platform 313 is greater than the inner diameter of the bearing hole of the bearing.

[0062] That is to say, in the first structure, the bearing is arranged within the convex boss 131 of the top plate 13. One end of the screw rod 31 with the convex platform 313 passes through the bearing, and the threaded section 312 is screwed into the riveted nut on the base 2. The bearing serves to facilitate the rotation of the screw rod 31 and support the device 1 to be lifted and lowered. When the screw rod 31 rotates within the nut, the bearing at the upper end of the screw rod 31 allows the screw rod 31 to rotate; the bearing is placed within the convex boss 131, and there is a necked-down portion at the upper end of the convex boss 131 to prevent the bearing from passing through the convex boss 131; in addition, since the bearing is within the convex boss 131 and rotation is required, the bearing and the convex boss 131 can be in interference fit or clearance fit, and interference fit is preferred.

[0063] Moreover, the diameter of the smooth section 311 of the screw rod 31 is smaller than the diameter of the threaded section 312. The smooth section 311 can pass through the bearing hole and is in clearance fit with the bearing. When the convex platform 313 on the screw rod 31 causes the screw rod 31 to rotate, the threaded section 312 cannot pass through the bearing hole, so that the device to be lifted and lowered can move up and down along with the screw rod 31. In addition, an internal hexagonal hole 314 (or other structures convenient for rotating the screw rod) is provided at the upper end of the screw rod 31 for rotating the screw rod 31.

[0064] When assembling this solution, first screw the screw 31 into the nut so that the length of the screw 31 above the base 2 is lower than the height of the device 1 to be lifted and lowered, which facilitates the assembly of the device 1 to be lifted and lowered. Then fix the bearing into the convex hull 131 of the top plate 13, and then assemble the fixing component 4 onto the base 2. Then place the device 1 to be lifted and lowered onto the base 2, align the screw with the bearing hole on the top plate 13, rotate the screw 31, pass the screw 31 through the bearing, and finally fix the fixing component 4 and the base 2 with bolts to complete the assembly, as Figure 1 shown.

[0065] When the device 1 to be lifted and lowered needs to sink, first remove the fixing component 4, and then use an Allen key tool to rotate the screw 31 in multiple times. As the screw 31 rotates clockwise, under the gravitational force of the device 1 to be lifted and lowered and the drive of the rotation of the screw 31, the device 1 to be lifted and lowered will slowly move downward along with the screw 31 to complete the sinking of the device 1 to be lifted and lowered. Finally, fix the top plate 13 to the base 2 with bolts. After sinking, there is no need to remove the screw 31, as Figure 2 shown.

[0066] When the device 1 to be lifted and lowered needs to be lifted, first remove the bolts fixed between the top plate 13 and the base 2, and then use an Allen key tool to rotate the screw 31 counterclockwise. The screw 31 will move upward. Since there is a boss 313 on the screw 31, the screw 31 cannot pass through the bearing, and the diameter of the bearing is larger than the through hole at the center of the convex hull 131 on the top plate 13. Therefore, when the screw 31 is rotated counterclockwise after being fitted with the bearing, the screw 31 will slowly push the device 1 to be lifted and lowered upward, so that the device 1 to be lifted and lowered will slowly move upward along with the screw 31, and finally complete the lifting of the device 1 to be lifted and lowered, as Figure 1 shown. Finally, fix the device 1 to be lifted and lowered to the base 2 with the fixing component 4.

[0067] Second, as Figures 10 - 18 shown, the first connecting portion 32 is located inside the top plate 13, the second connecting portion 33 is located inside the base 2, and the nut is located inside the top plate 13, and the bearing is located inside the base 2; in this setting method, as Figure 15 shown, the base 2 has a bearing groove 22 for fixing the bearing; and H4 > H5 + H6, where H4 is the depth of the bearing groove 22, H5 is the height of the bearing, and H6 is the height of the nut protruding from the upper surface of the top plate 13, so as to facilitate the top plate 13 and the base 2 to fit and seal to prevent air leakage.

[0068] In a specific embodiment, the base 2 also has a screw groove 23 for accommodating the screw, and the depth of the screw groove 23 is greater than or equal to the outer diameter of the screw.

[0069] In a specific embodiment, the screw 31 has a smooth section 311 and a threaded section 312. The smooth section 311 passes through the bearing, and the threaded section 312 cooperates with the nut. At the lower end of the screw 31, there is a part with a diameter smaller than that of the screw 31 for clearance fit with the bearing. In addition, an internal hexagonal hole 314 (or other structures convenient for rotating the screw) is provided at the upper end of the screw 31 for rotating the screw 31.

[0070] During the assembly of this solution, a bearing is assembled in the bearing groove 22 of the base 2, the fixing component 4 is assembled to the bottom of the device 1 to be lifted, and then the screw 31 is screwed into the nut so that the length of the part of the screw 31 below the top plate 13 is slightly less than the height of the device 1 to be lifted, facilitating the assembly of the device 1 to be lifted. Then, the device 1 to be lifted is placed on the base 2, and then the screw 31 is aligned with the bearing of the base 2. The screw 31 is rotated so that the smooth section 311 at the lower end of the screw 31 passes through the bearing hole. Finally, the fixing component 4 is fixed to the base 2 with bolts to complete the assembly, as Figure 10 shown.

[0071] When the device 1 to be lifted needs to sink, first remove the fixing component 4, and then use an internal hexagonal tool to rotate the screw 31. Since the lower end of the screw 31 and the bearing are fixed inside the bearing groove 22 of the base 2 and cannot move downward, when the screw 31 is rotated clockwise, driven by the gravity of the device 1 to be lifted and the rotational force of the screw 31, the device 1 to be lifted will slowly move downward as the screw 31 rotates, and finally the sinking of the device 1 to be lifted is completed, as Figure 11 and 12 shown; finally, the top plate 13 is fixed to the base 2 with bolts. After the sinking of the device 1 to be lifted is completed, the screw 31 protrudes above the top plate 13, and the screw 31 can be unscrewed and placed in the screw groove 23 of the base 2, as Figure 13 shown.

[0072] When the device 1 to be lifted needs to be lifted, first take out the screw 31 from the screw groove 23, screw it into the riveting nut of the base 2, then remove the bolt fixing the top plate 13, and then use an internal hexagonal tool to rotate the screw 31 counterclockwise. Since the lower end of the screw 31 and the bearing are fixed inside the bearing groove 22 of the base 2 and cannot move downward, when the screw 31 is rotated counterclockwise, the riveting nut on the top plate 13 will move upward relative to the screw 31, thereby driving the device 1 to be lifted upward, so that the device 1 to be lifted slowly moves upward as the screw 31 rotates, and finally the lifting of the device 1 to be lifted is completed, as Figure 10 shown; finally, the device 1 to be lifted is fixed to the base 2 with the fixing component 4.

[0073] In a specific embodiment, two rotating components 3 are provided. One ends of the two rotating components 3 are respectively located on both sides of the base 2, and the other ends of the two rotating components 3 are respectively connected to both sides of the top plate 13.

[0074] The two rotating components 3 can enable the device 1 to be lifted and lowered stably. When operating the rotating components 3, the rotating components 3 on both sides can be operated alternately.

[0075] The lifting structure provided in this embodiment realizes the rising and sinking of the device to be lifted by adopting a combination of a screw rod and a bearing, without the need to add a motor driving device, and has simple operation and low cost.

[0076] Embodiment 2

[0077] This embodiment provides a blower, and the blower includes the lifting structure of Embodiment 1.

[0078] That is to say, in Embodiment 1, the device 1 to be lifted is a blower, and the body 14 to be lifted is a blower body; by using the lifting structure in Embodiment 1 in this embodiment, the method of lifting the blower that requires multiple people is changed to that a single person can complete the lifting of the blower. The lifting process is simple and convenient, saving labor costs, and avoiding safety accidents during the lifting process by manpower, making the operation safer and more reliable.

[0079] Of course, the lifting structure in Embodiment 1 can be used to lift other heavy objects in addition to lifting the blower assembly.
