DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0042] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0043] As described in the background technology, when hoisting a target part such as a ceiling unit on a mounting surface, an operator is required to pre-open bolt holes on the top mounting surface, then hold the target part against the mounting surface by hand, and then pass the expansion bolts through the mounting holes on the target part and connect them with the bolt holes on the mounting surface to fix the ceiling unit. Finally, the ceiling unit needs to be leveled.

[0044] The target part can be an electrical device such as a ceiling air conditioner, ceiling fan, chandelier or projector installed on the installation surface in the form of a hoist, or a furniture device such as a wall cabinet, a cabinet, a bookshelf or a hanging TV bracket, or an indoor ventilation duct, etc. The installation surface can be located indoors, such as a ceiling wall, a suspended ceiling, etc., or outdoors.

[0045] When leveling, the operator needs to screw the expansion bolt upward from the bottom of the ceiling machine to adjust the installation angle of the ceiling machine, and then use a tool to measure whether the installation angle is appropriate from the side of the ceiling machine. Repeat this operation several times until the ceiling machine is adjusted to the appropriate installation angle. During the repeated operation, the operator needs to constantly change the position between the bottom and the side of the ceiling machine, or two or more operators are required to cooperate in leveling.

[0046] Therefore, this operation mode requires the operator to hold the target part by hand for a long time, the installation operation is relatively complicated, and the leveling operation is inconvenient.

[0047] The following is a detailed introduction to the hanging device, ceiling machine and various possible implementation forms provided by the present application in combination with specific implementation methods.

[0048] Figures 1 to 6 The schematic diagram of each component of the lifting device and the ceiling machine is shown. The specific structure of the remaining components of the lifting device and the ceiling machine is not limited to Figures 1 to 6 of examples.

[0049] On the one hand, referring to Figures 1 to 6 As shown, an embodiment of the present application provides a lifting device for mounting a target part on a mounting surface. The lifting device includes a track assembly 100 and at least one worm gear lifting unit 200. The track assembly 100 includes a first track 110 and a second track 120 disposed on the first track 110. The first track 110 is used to connect with the target part, such as a ceiling machine body 300. The second track 120 is used to connect with the mounting surface. The worm gear lifting unit 200 is disposed on the second track 120 to connect with the target part.

[0050] The worm gear lifting unit 200 is configured to drive the target part to drive the first track 110 to rise and fall relative to the second track 120 so that the target part abuts against or is out of abutment with the installation surface.

[0051] It is understandable that when installing the ceiling machine body 300, it needs to be at least partially flush with the installation surface of the indoor ceiling to achieve ceiling attachment. However, in actual installation, the installation surface is not a completely horizontal surface and there are uneven positions. Therefore, it is also necessary to adjust the actual setting angle of the ceiling machine body 300 so that the ceiling machine body 300 can smoothly discharge condensed water to avoid condensed water from gathering and being unable to be discharged. When the ceiling machine body 300 is installed, only the air outlet 310 of the ceiling machine body 300 or the side where the air outlet 310 is located is exposed.

[0052] When the ceiling machine body 300 is installed by using the hoisting device provided in this embodiment, the operator can first install the second track 120 at the preset installation position of the installation surface, and then connect the ceiling machine body 300 to the first track 110, and then connect the first track 110 and the second track 120 to connect the ceiling machine body 300 to the installation surface. At this time, in order to avoid mutual interference when the ceiling machine body 300 is connected to the installation surface and facilitate the operator to subsequently adjust the installation angle of the ceiling machine body 300, a gap is left between the side of the ceiling machine body 300 facing the installation surface and the installation surface.

[0053] Then, the operator sets the worm gear lifting unit 200 on the second track 120, or pre-installs the worm gear lifting unit 200 before that, and uses the worm gear lifting unit 200 to drive the ceiling machine body 300 through the worm gear lifting unit 200, and makes the ceiling machine body 300 drive the first track 110 to rise and move toward the installation surface, so that the ceiling machine body 300 is flush with the installation surface, and in this process, the worm gear lifting unit 200 is used to adjust the rising height of the ceiling machine body 300 to adjust the installation angle of the ceiling machine body 300 to ensure that condensed water can be discharged smoothly.

[0054] During the installation process of the ceiling machine body 300, since the first rail 110 is connected to the installation surface in advance, the operator only needs to connect the ceiling machine body 300 with the second rail 120 through the first rail 110 and then connect the ceiling machine body 300 to the installation surface. There is no need to continue to manually support the ceiling machine body 300 for subsequent operations, making the installation operation of the ceiling machine body 300 more labor-saving, convenient and efficient.

[0055] When the ceiling machine body 300 needs to be maintained and overhauled, the operator can use the worm gear lifting unit 200 to drive the first track 110 to descend, that is, move in a direction away from the installation surface, and drive the ceiling machine body 300 to move synchronously, so that the operator can perform maintenance and overhaul.

[0056] It can be understood that the worm gear structure has the characteristics of smooth transmission and self-locking characteristics, that is, the friction between the worm gear structure is used to achieve power output only from the worm to the worm wheel, and the worm wheel cannot reversely drive the worm, thereby making the worm the active component and the worm wheel the driven component. Therefore, the use of the worm gear lifting unit 200 can make the ceiling attachment process of the ceiling machine body 300 smoother and more labor-saving, and when the operator uses the worm gear lifting unit 200 to control the lifting of the ceiling machine body 300, as long as the operator stops inputting power to the worm gear lifting unit 200, the worm gear lifting unit 200 can limit the ceiling machine body 300 to the current position by itself through the self-locking characteristics, thereby ensuring the stability of the installation of the ceiling machine body 300, making the installation of the ceiling machine body 300 more stable and reliable.

[0057] When setting up specific settings, refer to Figure 1 As shown, two track assemblies 100 need to be set on the tops of the two opposite sides of the ceiling machine body 300, and at least one worm gear lifting unit 200 is set on each of the two track assemblies 100 to ensure that the connection between the ceiling machine body 300 and the installation surface is stable and reliable to avoid imbalance.

[0058] In this embodiment, two worm gear lifting units 200 are provided on each side track assembly 100 so that the lifting height adjustment of the ceiling machine body 300 at both ends along the extension direction of the track assembly 100 can be more flexible.

[0059] In some embodiments, reference Figure 5 and Figure 6 As shown, the first track 110 includes a first mounting portion 111 and a first connecting portion 112 arranged on the first mounting portion 111, the first mounting portion 111 is located on one side of the first connecting portion 112, and the first mounting portion 111 is used to be fixedly connected to the target part (ceiling machine body 300), the second track 120 includes a second mounting portion 121 and a second connecting portion 122 arranged on the second mounting portion 121, the second mounting portion 121 is located on one side of the second connecting portion 122, the second mounting portion 121 is used to be fixedly connected to the mounting surface, and the first connecting portion 112 is embedded in the second connecting portion 122; the worm gear lifting unit 200 is constructed to drive the target part to drive the first connecting portion 112 to rise and fall relative to the second connecting portion 122.

[0060] In this way, the structures of the first rail 110 and the second rail 120 can be simple and compact, and the first rail 110 and the second rail 120 can be connected to each other through the first connecting portion 112 and the second connecting portion 122. The first mounting portion 111 and the second mounting portion 121 can also achieve stable and reliable connection with the ceiling machine body 300 and the mounting surface respectively, ensuring that the ceiling machine body 300 is stably and reliably installed.

[0061] The second mounting portion 121 is used to abut against the mounting surface, the first mounting portion 111 is located on a side of the first connecting portion 112 away from the second mounting portion 121 , and the first mounting portion 111 is used to connect with a side surface of the target component.

[0062] Such arrangement can make the structure of the track assembly 100 more reasonable, avoid mutual interference between the first mounting portion 111 and the second mounting portion 121, and affect the ceiling-attaching effect of the ceiling machine body 300, and also facilitate the worm gear lifting unit 200 to perform the lifting operation of the first track 110 and the second track 120. In addition, the first mounting portion 111 is connected to the side of the target part, which can make the ceiling-attaching installation of the target part and the mounting surface more complete.

[0063] In addition, the first track 110 further includes a connecting portion 113 , the second connecting portion 122 has a sliding groove, the first connecting portion 112 is slidably embedded in the sliding groove, and the first connecting portion 112 is connected to the first mounting portion 111 via the connecting portion 113 .

[0064] In this way, the sliding connection between the first rail 110 and the second rail 120 can be easily achieved through the mutual sliding cooperation of the first connecting part 112 and the second connecting part 122, so that the operator can lift the ceiling machine body 300, dock the first rail 110 and the second rail 120, and then slide them into place to complete the connection between the first rail 110 and the second rail 120.

[0065] In a specific implementation, the second connection portion 122 is located below the first connection portion 112, so that the worm gear lifting unit 200 can drive the ceiling machine body 300 to rise, thereby driving the first track 110 to be pushed and disconnected from the second track 120. And by providing a connecting portion 113 to connect the first connection portion 112 and the first mounting portion 111, the first mounting portion 111 can avoid the worm gear lifting unit 200 to avoid interference between the two.

[0066] In some embodiments, reference Figures 1 to 6 As shown, the worm gear lifting unit 200 includes a housing 210, a worm gear lifting assembly 220 and a rack 230, the rack 230 is used to be set on the target part, the housing 210 is detachably connected to the second track 120, the second track 120 is located between the housing 210 and the first track 110, the housing 210 has a receiving cavity, the worm gear lifting assembly 220 is located in the receiving cavity and meshes with the rack 230; the worm gear lifting assembly 220 is configured to drive the rack 230 to move so that the rack drives the target part to rise and fall. Specifically, the second connecting portion 122 is located between the housing 210 and the first connecting portion 112.

[0067] Since the first track 110 needs to move toward the installation surface and separate from the second track 120, the first track 110 is relatively located on the side of the second track 120 facing the installation surface. In order to avoid interference between the worm gear lifting unit 200 and the first track 110, the housing 210 of the worm gear lifting unit 200 can be set on the other side of the second track 120 opposite to the first track 110, and can be detachably connected to the second track 120, with a compact and stable structure. When the ceiling machine body 300 is installed by the lifting device, the ceiling machine body 300 can be connected to the installation surface by the first track 110 and the second track 120, and after the first track 110 and the second track 120 slide into place, the worm gear lifting unit 200 can be installed on the second track 120 and the ceiling machine body 300. The worm gear lifting assembly 220 is disposed in the housing 210 , the housing 210 is connected to the second track 120 , and the rack 230 is disposed on the ceiling machine body 300 and meshes with the worm gear lifting assembly 220 .

[0068] By setting the shell 210 on the second track 120, the worm gear lifting assembly 220 can be indirectly fixedly connected to the installation surface through the second track 120, thereby fixing the relative position of the worm gear lifting assembly 220 and the installation surface, making it easier for the worm gear lifting assembly 220 to stably and reliably drive the rack 230 on the ceiling machine body 300 to move, and drive the ceiling machine body 300 and the first track 110 to move relative to the second track 120 through the rack 230.

[0069] The rack 230 may be a rack structure integrally arranged on the side of the ceiling machine body 300, or may be a rack structure additionally fixed on the side of the ceiling machine body 300, and the present application does not impose any limitation on this.

[0070] After the ceiling machine body 300 is connected to the installation surface through the track assembly 100, there is a gap between the ceiling machine body 300 and the installation surface. Therefore, when the worm gear lifting unit 200 drives the ceiling machine body 300 to rise toward the installation surface, the first track 110 and the second track 120 will be disconnected, so that the ceiling machine body 300 is close to the ceiling; when the worm gear lifting unit 200 drives the ceiling machine body 300 to move away from the installation surface and descend, the first track 110 and the second track 120 will be connected again to facilitate the subsequent maintenance and repair of the ceiling machine body 300.

[0071] Since the track assembly 100 is located as a whole on the side of the ceiling machine body 300, the space on the side of the shell 210 facing the ceiling machine body 300 is relatively narrow. An opening connected to the accommodating cavity can be opened on the side of the shell 210 facing the ceiling machine body 300 to facilitate the engagement of the worm gear lifting assembly 220 with the rack 230, and the worm gear lifting assembly 220 can be operated from the side of the shell 210 opposite to the opening to drive the rack 230 to move.

[0072] Compared with the operator constantly changing the position of the ceiling machine body 300 below and to the side to level the ceiling machine body 300, the lifting device provided in the present application can also be set as a whole on the side of the ceiling machine body 300, and the installation angle adjustment operation and corresponding measurement operation of the ceiling machine body 300 can be performed simultaneously from the side of the ceiling machine body 300, so that the leveling of the ceiling machine body 300 is more efficient and quick.

[0073] In specific implementation, refer to Figures 4 to 6As shown, the worm gear lifting assembly 220 includes a worm 221, a worm wheel 222 and a rotating shaft 223. The worm 221 is rotationally connected to the housing 210, the worm wheel 222 is meshed with the worm 221, and is rotationally connected to the rotating shaft 223. The rotating shaft 223 is rotationally connected to the housing 210, the rack 230 is meshed with the worm wheel 222, and the extension direction of the rack 230 is tangent to the rotation direction of the worm wheel 222; the rack 230 is constructed to move along the rotation direction of the worm wheel 222 when the worm 221 drives the worm wheel 222 to rotate, so as to drive the target part to rise and fall.

[0074] It should be noted that, based on the self-locking characteristics of the worm gear lifting assembly 220, the worm 221 is set as an active component so that the operator can apply an external force to the worm 221, which can be a torque to drive the worm 221 to rotate, so that the worm 221 converts the rotation around the axis of the worm 221 into the rotation around the axis of the worm wheel 222, wherein the axis of the worm 221 and the axis of the worm wheel 222 can be set to be perpendicular to each other. The worm wheel 222 further converts the rotational motion into the moving motion of the rack 230. The overall structure is simple, the transmission is stable, and it has a self-locking performance, so that the reliability of the lifting device is better.

[0075] The worm gear 222 and the rotating shaft 223 are connected by a key, such as a flat key, and both ends of the rotating shaft 223 are rotatably connected to the housing.

[0076] A knob 224 may also be provided on the worm 221. One end of the worm 221 for the operator to apply force is located outside the accommodating cavity, and the knob 224 is provided at this end so that the operator can better screw the worm 221. Alternatively, a rocker may be provided at this end, which is not limited in the present application.

[0077] Specifically, since the rack 230 is integrally embedded in the side surface of the ceiling machine body 300, in order to enable the worm gear 222 to mesh smoothly with the rack 230, it is necessary to set the worm gear 222 toward the rack 230 so that the worm gear 222 is partially located outside the opening of the shell 210. In this way, when the ceiling machine body 300 slides along the second track 120 along the first track 110, it is easy for the worm gear 222 to interfere with the side of the ceiling machine body 300, so a detachable connection is provided between the shell 210 and the second track 120. In some embodiments, refer to Figures 4 to 6As shown, a clamping portion 123 is provided on the second track 120, and a clamping hole 212 corresponding to the clamping portion 123 is provided on the housing 210, and the clamping hole 212 is detachably connected to the clamping portion 123. By providing the clamping portion 123 and the corresponding clamping hole 212, the housing 210 and the second track 120 are detachably connected. The overall structure is simple and easy to operate, and the stability after connection is good. Specifically, the clamping portion 123 is a claw arranged on a side of the second connecting portion 122 away from the first connecting portion 112, and extending away from the second connecting portion 122, and the end of the claw is provided with an inclined surface, so that the clamping hole 212 is stopped after being plugged in, so as to prevent the housing 210 from falling. In the specific implementation, in order to further ensure the reliability of the connection between the housing 210 and the second track 120, after the clamping portion 123 is clamped with the clamping hole 212, the housing 210 and the second track 120 can also be connected by other reinforcements such as bolts, and this application does not limit this.

[0078] Furthermore, a limiting portion 114 is disposed on the first track 110 , and a limiting groove 213 corresponding to the limiting portion 114 is disposed on the housing 210 , and the limiting groove 213 is in sliding contact with the limiting portion 114 .

[0079] It should be noted that by providing the limiting portion 114 and the limiting groove 213, when the shell 210 is connected to the second track 120, the limiting portion 114 can be located in the limiting groove 213, and when the worm gear lifting assembly 220 drives the ceiling machine body 300 to rise and fall, the limiting portion 114 can slide relatively in the limiting groove 213 and realize limiting guidance, thereby ensuring the relative position relationship between the shell 210 and the ceiling machine body 300, ensuring the stable engagement of the worm gear 222 and the rack 230, and avoiding the horizontal movement of the ceiling machine body 300 when it is raised and lowered.

[0080] Among them, the limiting portion 114 is a bending section arranged on the first mounting portion 111, and the limiting groove 213 is a groove arranged on the shell. The depth of the groove can be set according to the maximum lifting stroke of the ceiling machine body, or the limiting groove 213 can pass through the shell, and the present application does not impose any restrictions on this.

[0081] Furthermore, in order to enable the worm 221 and the worm wheel 222 to rotate smoothly in the accommodating chamber, a stable support structure needs to be provided in the accommodating chamber. Therefore, the housing 210 is provided with a support portion 211, the support portion 211 is located in the accommodating chamber, and the worm 221 is rotatably connected to the support portion 211.

[0082] The support part 211 is a plate disposed in the housing 210 to support the worm 221 at a fixed position and allow the worm 221 to rotate relative to the plate. Both ends of the worm 221 should also abut against the housing 210 and be rotationally connected to the abutting position.

[0083] In other embodiments, the support portion 211 may be any structure that can ensure the relative position of the worm gear lifting assembly 220 and be rotationally connected thereto, and the present application does not impose any limitation thereto.

[0084] In the specific connection, the track assembly 100 further includes a fastener (not shown), and the first track 110 is used to connect with the target part through the fastener, and / or the second track 120 is used to connect with the mounting surface through the fastener. A mounting hole 130 is provided on at least one of the first mounting portion 111 and the second mounting portion 121, and the fastener is used to be fixedly connected with at least one of the top of the side of the ceiling machine body 300 and the mounting surface through the mounting hole 130. A plurality of mounting holes 130 are sequentially arranged at intervals along the extending direction of the first mounting portion 111 and the second mounting portion 121.

[0085] The fasteners can ensure reliable connection between the first mounting portion 111 and the ceiling machine body 300, and between the second mounting portion 121 and the mounting surface. When the first mounting portion 111 is connected to the ceiling machine body 300, the fasteners can be conventional bolts or screws; when the second mounting portion 121 is connected to the mounting surface, the fasteners can be expansion bolts to prevent them from falling out under the gravity of the ceiling machine body 300.

[0086] Furthermore, after the worm gear lifting unit 200 has adjusted the installation angle of the ceiling machine body 300 to a suitable level, fasteners can be used to sequentially pass through the first connection portion 112 and the second connection portion 122 to fix the relative positions of the first connection portion 112 and the second connection portion 122, thereby fixing the ceiling machine body 300 at the current installation angle. Subsequently, the worm gear lifting unit 200 can be removed, so that the installation of the ceiling machine body 300 is safer and more reliable, and the overall appearance is simpler and neater.

[0087] Therefore, the specific operation of the lifting device provided in the embodiment of the present application is as follows:

[0088] First, the first rail 110 is fixedly connected to the top of both sides of the ceiling machine body 300, and the second rail 120 is fixedly connected to the set installation position on the installation surface;

[0089] Then the operator lifts the ceiling machine body 300 to the set installation position of the installation surface, so that the end of the first track 110 away from the air outlet 310 is connected with the end of the second track 120 facing the air outlet 310, and then pushes the ceiling machine body 300 so that the first track 110 slides into place relative to the second track 120, forming a Figure 1 In the structure shown in FIG. 1 , the first track 110 and the second track 120 are in contact with each other in the vertical direction, and there is a gap between the top surface of the ceiling machine body 300 and the installation surface. Figure 5 As shown;

[0090] Then, the operator installs the worm gear lifting assembly 220 on the second track 120 through the housing 210, and meshes it with the rack 230, and then rotates the worm 221, so that the worm 221 drives the worm wheel 222 to rotate, and the worm wheel 222 drives the rack 230 to move, so as to drive the ceiling machine body 300 to rise toward the installation surface, until the top surface of the ceiling machine body 300 at least partially touches the installation surface, as shown in the figure. Figure 6 As shown, the installation of the ceiling machine body 300 is completed. In this operation step, the operator can adjust the height of the lifting rod 223 pushing the first track 110 according to specific installation requirements to adjust the installation angle of the ceiling machine body 300.

[0091] When it is necessary to maintain and overhaul the ceiling unit main body 300, the above steps can be performed in reverse.

[0092] On the other hand, the embodiment of the present application further provides a ceiling machine body 300, comprising the ceiling machine body 300 and the hanging device in any of the above embodiments, the hanging device is connected to the ceiling machine body 300. The hanging device has been described in detail in the above embodiments, and will not be repeated here.

[0093] In summary, the ceiling machine provided in the present application is equipped with a lifting device, and the lifting device is equipped with a track assembly 100, so that the first track 110 of the track assembly 100 is connected to the ceiling machine body 300, and the second track 120 of the track assembly 100 is connected to the top mounting surface of the ceiling machine body 300, and the ceiling machine body 300 is driven by the worm gear lifting unit 200 to drive the first track 110 to rise and fall relative to the second track 120, so that the ceiling machine body 300 is at least partially in contact with the mounting surface.

[0094] In this way, when installing the ceiling machine body 300, the track assembly 100 is first pre-installed on the installation surface, and the ceiling machine body 300 is connected to the track assembly 100, so that the ceiling machine body 300 is hoisted on the installation surface through the track assembly 100, and then the worm gear lifting unit 200 is used to drive the ceiling machine body 300 to move toward the installation surface so that the ceiling machine body 300 is in contact with the installation surface to achieve the ceiling installation of the ceiling machine. During the operation, the operator can avoid holding the ceiling machine body 300 for a long time for installation, and the installation angle of the ceiling machine body 300 can be adjusted by the worm gear lifting unit 200, making the installation of the ceiling machine more convenient, quick and efficient.
