[0042] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0043] 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.

[0044] In the prior art, when a target part (for example, the indoor unit of a ceiling-mounted air conditioner, i.e., a ceiling unit) is hoisted, expansion bolts are usually used to connect the target part and the corresponding mounting surface of the target part. During the installation process, the target part needs to be supported for a long time to ensure the relative position of the target part and the mounting surface, avoid displacement of the expansion bolts, and prevent an unstable connection between the target part and the mounting surface.

[0045] 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.

[0046] However, supporting the target part for a long time to connect it to the mounting surface is time-consuming and labor-intensive, inconvenient to operate, and there is a possibility that the target part will fall off during the supporting process.

[0047] Based on the above problems, the present application provides a lifting device and a ceiling machine. The lifting device is connected to the mounting surface through a bracket by setting a connecting component. When the ceiling machine and other target parts need to be installed, it is only necessary to move the mounting part toward the hanging part of the connecting component, so that the two hanging parts are driven away from each other to facilitate the movement of the mounting part between the two hanging parts. When the mounting part moves between the two hanging parts, the docking is completed, and the two hanging parts can be reset to support the mounting part from both sides of the mounting part. Then, the locking part of the connecting component is used to lock the two hanging parts, so that the ceiling machine and the connecting component can be stably hung. This connection method has lower requirements on the docking accuracy of the ceiling machine and is more convenient for docking. The connecting component can also be used to stably hang the ceiling machine on the mounting surface, making the docking installation of the ceiling machine more convenient, quick and efficient.

[0048] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can exist independently or in combination with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0049] The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0050] Reference Figure 1 and Figure 2 As shown, the lifting device provided in the embodiment of the present application is used to install the target part on the installation surface. The lifting device includes a bracket 100 and a connecting assembly 200. The bracket 100 is used to be connected to the installation surface. The connecting assembly 200 includes a mounting member 310, a locking member 220 and two hanging members. The mounting member 310 is used to be set on the target part, and the hanging member is set on the bracket 100.

[0051] The mounting member 310 drives the two hanging members to move away from each other, so that the two hanging members jointly support the mounting member 310 through both sides of the mounting member 310;

[0052] The locking member 220 moves relative to the hanging member to lock or unlock the two hanging members.

[0053] The bracket 100 is connected to the mounting surface, specifically, a connection hole 111 is opened on the bracket 100, and the bracket 100 is pre-stably mounted on the mounting surface using expansion bolts, or it can be fixedly connected to a corresponding connecting frame or other structure on the mounting surface, and the present application does not impose any restrictions on this.

[0054] A connecting component 200 is provided on the bracket 100 and can be located on a side of the bracket 100 away from the mounting surface. The connecting component 200 includes a mounting member 310 connected to the target member, a hanging member connected to the bracket 100 and a locking member 220 for locking or unlocking the hanging member.

[0055] It should be noted that, in this embodiment, the target part is Figure 1 The ceiling machine body 300 shown in the figure, the mounting member 310 of the hanging device is specifically connected to the ceiling machine body 300, so that the ceiling machine body 300 can be hung on the installation surface by hanging the mounting member 310 with the hanging member. In other feasible embodiments, the target part can also be an electrical device such as a ceiling fan, a chandelier or a projector installed on the installation surface in the form of hanging, or a furniture device such as a wall cabinet, a cabinet, a bookshelf or a hanging TV bracket 100, or an indoor ventilation duct, etc. The installation surface can be located indoors, such as a ceiling wall, a suspended ceiling, etc., or it can be located outdoors.

[0056] Therefore, when it is necessary to hang the target part with the lifting device, the target part can drive the mounting part 310 to move to the hanging part, so that the ends of the mounting part 310 and the hanging part are abutted, and then the hanging parts are driven away from each other to facilitate the mounting part 310 to move between the two hanging parts. When the mounting part 310 moves between the two target parts, the two hanging parts are reset, and the two side surfaces of the mounting part 310 are supported by the opposite sides of the two hanging parts. Then, the two hanging parts are locked by using the locking part 220 to limit the mounting part 310 from falling out from between the two hanging parts, thereby realizing stable hanging of the target part and the lifting device.

[0057] When it is necessary to detach the target component from the hanging device, the locking component 220 can be moved in the reverse direction to unlock the two hanging components, so as to remove the mounting component 310 from between the two hanging components.

[0058] Compared with aligning the mounting holes on the ceiling machine body 300 with the bolt holes on the mounting surface to achieve docking, the present application uses a lifting device that only requires the mounting part 310 set on the ceiling machine body 300 to drive the two hanging parts away from each other, and then resets the mounting part 310 to be located between the two hanging parts, and supports the mounting part 310 from both sides to achieve docking. After docking, the two hanging parts can be locked using the locking part 220. The docking operation requires lower accuracy and is more convenient to operate.

[0059] Therefore, the hoisting device provided by the present application is provided with a bracket 100 and a connecting assembly 200 connected to the bracket 100, so that the bracket 100 is pre-connected with the installation surface, and the mounting member 310 of the connecting assembly 200 is connected with the ceiling machine. Since the connecting assembly 200 has a hanging member that can be moved away from each other and reset, it is only necessary to use the mounting member 310 to drive the hanging member so that the two hanging members form a support for the mounting member 310 after passing through the two sides of the mounting member 310, and then use the locking member 220 to lock the hanging member, so that the ceiling machine body 300 and the connecting assembly 200 can be docked, and the docking accuracy requirements for the ceiling machine body 300 are lower, and it is more convenient to dock, and the connecting assembly 200 can be used to stably hang the ceiling machine on the installation surface, making the docking installation of the ceiling machine more convenient, quick and efficient.

[0060] It should be noted that, depending on the number of hanging structures provided on the target part, different numbers of hoisting devices may be provided to connect with the target part. Figure 1 As shown, four mounting parts 310 are arranged on opposite sides of the ceiling machine body 300, so four lifting devices can be arranged to realize the connection between the ceiling machine body 300 and the mounting surface. When the target part is other equipment or components, only one, two or three or more lifting devices can be arranged to be connected with the corresponding ones, and the present application does not impose any restrictions on this.

[0061] In some embodiments, reference Figures 1 to 5As shown, the hanging member includes a clamping jaw 210 and a matching portion 212 disposed on the clamping jaw 210, and the two clamping jaws 210 together form a hanging portion 213 supporting the mounting member 310;

[0062] The locking member 220 moves relative to the clamping jaws 210 to connect or disconnect with the matching portion 212. When the locking member 220 is connected with the matching portion 212, the two clamping jaws 210 are locked. When the locking member 220 is disconnected from the matching portion 212, the two clamping jaws 210 are unlocked.

[0063] It can be understood that the hanging member is set as a clamping jaw 210 connected to the bracket 100, and the structure of the clamping jaw 210 itself is used to form the hanging portion 213. Moreover, by the relative distance between the clamping jaw 210, an entrance and exit that is connected to the hanging portion 213 and can be opened and closed can be formed at the end of the clamping jaw 210 that is relatively far away from the bracket 100, so that the installation member 310 can enter and exit the hanging portion 213 between the two clamping jaws 210 through the entrance and exit. When the installation member 310 enters the hanging portion 213 between the two clamping jaws 210 through the entrance and exit, it can be hung with the hanging portion 213.

[0064] Specifically, when the ends of the two jaws 210 away from the bracket 100 abut against each other, the entrance and exit can be closed accordingly. When the ends of the two jaws 210 away from the bracket 100 are disengaged from the abutment, the entrance and exit are opened. In this way, the entrance and exit can be opened and closed by the relative movement of the jaws 210.

[0065] Such an arrangement makes the overall structure of the connection component 200 relatively simple and compact, reduces the accuracy requirement for docking the ceiling unit body 300 and the connection component 200, and makes the docking operation simpler and easier.

[0066] When the two clamping jaws 210 are in contact, the locking member 220 moves along the clamping jaws 210 and connects with the matching portion 212 to lock the two clamping jaws 210. This can ensure the stability of the connection between the connecting component 200 and the target part, and prevent the two clamping jaws 210 from accidentally opening the entrance and exit, causing the target part to fall off. The result is simple and easy to operate.

[0067] In some embodiments, reference Figures 1 to 5 As shown, the hanging portion 213 is a hanging groove, and the two clamping jaws 210 are arranged opposite to each other, and the ends of the two clamping jaws 210 away from the bracket 100 are abutted and matched to form a hanging groove on the opposite side of the two clamping jaws 210.

[0068] It can be understood that the two clamping claws 210 are abutted to form a hanging groove-type hanging portion 213, which has a relatively simple structure and can make the hanging portion 213 have more sufficient accommodating space for the mounting member 310, making it easier for the mounting member 310 to dock with the hanging portion 213, further reducing the difficulty of docking and installing the target member with the connecting component 200.

[0069] Furthermore, in order to facilitate the abutment between the mounting member 310 and the hanging member to drive the two clamping jaws 210 away from each other, refer to Figures 1 to 5 As shown, a guide portion 211 is also provided on the clamping jaw 210 . The guide portion 211 is located on a side of the clamping jaw 210 away from the hanging portion 213 . The mounting member 310 drives the two clamping jaws 210 away from each other via the guide portion 211 .

[0070] It can be understood that by providing the guide portion 211 on the side of the clamping jaw 210 away from the hanging portion 213, the guide portion 211 can be expanded at the entrance and exit, making it easier for the mounting member 310 to enter the receiving groove through the entrance and exit.

[0071] Furthermore, since the guide portion 211 is provided with a flared opening at the entrance and exit, when the target part is moved to the entrance and exit and the entrance and exit is not opened, the mounting member 310 can be brought into contact with the guide portion 211, so that the target part can push the clamping jaws 210 out of contact with each other under the action of the guide portion 211, thereby automatically opening the entrance and exit, which is more convenient and labor-saving.

[0072] Exemplarily, the guide portion 211 may be provided on only one clamping jaw 210 , or may be provided on both clamping jaws 210 , and the present application does not impose any limitation on this.

[0073] In a specific implementation, the mounting member 310 can be set as a mounting pin, and the hanging portion 213 has an arc segment 2131 adapted to the mounting pin. When the mounting member 310 is set as a cylindrical mounting pin, by setting the bottom of the clamping jaw 210 corresponding to the hanging portion 213 as the arc segment 2131, when the two clamping jaws abut, the two arc segments 2131 can be spliced ​​into an arc structure, which is convenient for guiding the mounting member 310 on the ceiling machine body 300 to the center of the arc structure under the action of gravity, so that the relative position of the ceiling machine body 300 and the mounting surface is more stable.

[0074] In other embodiments, a sloped section may be provided on the opposite side of the two clamping jaws 210, and the two sloped sections may be assembled to form a V-shaped groove bottom. Similarly, the mounting part 310 of the ceiling machine body 300 may be guided to the center of the groove bottom by itself under the action of gravity. The present application does not impose any restrictions on this.

[0075] In other embodiments, a hanging portion 213 structure adapted to the peripheral structure of the mounting member 310 may also be provided according to the peripheral structure of the mounting member 310 , and the present application does not impose any limitation on this.

[0076] In addition, in some embodiments, reference Figures 1 to 5 As shown, the locking member 220 is a nut sleeved on the bracket 100 , and the matching portion 212 is an external thread provided on the clamping jaw 210 .

[0077] The matching portion 212 may be as follows: Figure 2As shown in the figure, the locking member 220 is arranged at the upper part of the clamping jaw 210, close to the bracket 100, so that the locking member 220 is sleeved on the matching portion 212 from top to bottom, or the matching portion 212 can also be arranged at the lower part of the clamping jaw 210, so that the locking member 220 is connected to the matching portion 212 from bottom to top, and the present application does not impose any restrictions on this.

[0078] The locking member 220 is set as a nut to be connected with the matching part 212 of the external thread structure. The operation is simple and the locking effect is stable and reliable, which is convenient for effectively ensuring the stable hanging state of the clamping claw 210 and the mounting member 310 to ensure the reliability of the installation of the ceiling machine body 300.

[0079] Moreover, in other embodiments, the locking member 220 can be set as a screw, and the matching portion 212 can be set as a threaded hole. The threaded holes are set on the two jaws 210 along the same axial direction, so that the screw and the threaded holes are threadedly connected, which can also achieve locking of the jaws 210. The present application does not impose any restrictions on this.

[0080] Further, see Figure 2 and Figure 5 As shown, a stopper 214 is further provided on the clamping jaw 210 , and the stopper 214 is connected to one side of the matching portion 212 so as to abut against the locking member 220 when the locking member 220 is connected to the matching portion 212 .

[0081] The stopper 214 can limit the maximum travel of the locking member 220 relative to the matching portion 212 to ensure the locking effect. When the locking member 220 is located above the clamping jaw 210, the stopper 214 can be used to prevent the locking member 220 from falling out of the connecting assembly 200.

[0082] In some embodiments, reference Figure 2 As shown, the bracket 100 includes a first connecting section 110 and two second connecting sections 120. The two second connecting sections 120 are respectively arranged on both sides of the first connecting section 110. The first connecting section 110 is used to connect to the installation surface, and the second connecting section 120 is connected to the hanging member.

[0083] Such an arrangement can make the structure of the bracket 100 simple and compact. Two second connecting sections 120 can be respectively arranged on both sides of the first connecting section 110, so that the connection between the clamping jaw 210 of the connecting assembly 200 and the bracket 100 is more stable and reliable.

[0084] Further, refer to Figure 2 As shown, the connection assembly 200 further includes a connection member 230 , and the hanging member is hingedly or slidably connected to the second connection section 120 via the connection member 230 .

[0085] In specific implementation, refer to Figures 2 to 5As shown, a through hole can be provided on the second connecting section 120, so that the connecting member 230 is inserted into the through hole, and the clamping jaw 210 can be hinged to the bracket 100 through the connecting member 230. By providing the connecting member 230, the clamping jaw 210 is hinged to the bracket 100, and the clamping jaw 210 can be rotated about the axis of the connecting member 230 to make the clamping jaw 210 move away from the other clamping jaw 210 under the action of an external force to break away from the abutment, and when the external force on the clamping jaw 210 is removed, the clamping jaw 210 can be reversely rotated and reset to abut against the other clamping jaw 210 by its own weight, so that the opening and closing action of the clamping jaw 210 is more convenient and quick, and is convenient for the fixing operation after docking.

[0086] Among them, only one clamping jaw 210 can be hinged to the bracket 100 through the connecting piece 230, and the other clamping jaw 210 can be fixedly connected to the bracket 100, or both clamping jaws 210 can be hinged to the bracket 100, which is not limited in the present application.

[0087] In other embodiments, a horizontal strip hole may be provided on the second connecting section 120, and at least one clamping jaw 210 may be provided to be slidably connected to the bracket 100 in the horizontal direction through the connecting member 230, so that the clamping jaw 210 can slide away from the other clamping jaw 210 to disengage from the abutment, and after the mounting member 310 is inserted into the receiving groove, the clamping jaw 210 can slide in the opposite direction to abut again.

[0088] In order to achieve the self-closing and abutment of the clamping jaw 210, an elastic member can be set in the sliding direction of the clamping jaw 210. When the clamping jaw 210 slides to open the entrance and exit, the elastic member accumulates elastic potential energy. When the mounting member 310 is inserted into the receiving groove, it can be reset to abut under the action of the elastic member.

[0089] Similarly, an elastic member may be installed when the clamping jaw 210 is hinged to the bracket 100 to facilitate faster rotation and reset of the clamping jaw 210 and make the clamping jaw 210 less susceptible to the influence of the setting direction. Whether the clamping jaw 210 is set vertically or horizontally, self-reset and abutment can be achieved.

[0090] An embodiment of the present application further provides a ceiling machine, comprising the hoisting device and a ceiling machine body 300 in any of the above embodiments, and the ceiling machine body 300 is connected to the installation surface through the hoisting device.

[0091] The hoisting device has been described in detail in the above embodiments and will not be described again here.

[0092] The ceiling machine provided in the embodiment of the present application is provided with a lifting device. The lifting device is provided with a connecting component 200, so that the connecting component 200 is connected to the installation surface through the bracket 100. When it is necessary to install a target part such as the ceiling machine, it is only necessary to move the mounting member 310 toward the hanging member of the connecting component 200, so that the two hanging members are driven by the mounting member 310 to move away from each other, so that the mounting member 310 can move between the two hanging members. When the mounting member 310 moves between the two hanging members, the docking is completed, and the two hanging members can be reset to support the mounting member 310 from both sides of the mounting member 310, and then the locking member 220 of the connecting component 200 is used to lock the two hanging members, so that the ceiling machine and the connecting component 200 can be stably hung. This connection method has lower requirements on the docking accuracy of the ceiling machine and is more convenient for docking. The connecting component 200 can also be used to stably hang the ceiling machine on the installation surface, making the docking installation of the ceiling machine more convenient, quick and efficient.
