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] As described in the background technology, the ceiling machine is installed by a hanging device, which includes a hanging assembly and a mounting frame. The mounting frame is installed on the mounting surface, and the hanging assembly is fixed on the mounting frame and connected to the ceiling machine. The hanging assembly drives the ceiling machine to rise and fall, and the ceiling machine is installed when it is lifted to a preset position on the mounting surface.

[0042] However, in this manner, the ceiling machine is held in a preset position by lifting the hanging assembly, which places a heavy load on the hanging assembly and shortens its service life, thereby causing poor stability and reliability in the installation of the ceiling machine.

[0043] In view of the above problems, the present application provides a hoisting device and a ceiling machine. The hoisting device is provided with a driving member on a mounting frame, a traction member is connected to the driving member, and the traction member is connected to a target member such as a ceiling machine, so that the driving member drives the traction member to drive the ceiling machine to rise or fall. When the ceiling machine rises to a preset position, the ceiling machine can be connected to the mounting frame by fasteners to achieve the installation of the ceiling machine, thereby preventing the driving member and the traction member from being in a long-term load state, thereby extending the service life of the driving member and the traction member, preventing the ceiling machine from falling due to failure of the driving member and the traction member, and making the installation of the ceiling machine more stable and reliable.

[0044] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments may 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. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Reference Figures 1 to 3 As shown, the lifting device provided in the embodiment of the present application is used to install the target part on the mounting surface. The lifting device includes a mounting frame 100, a driving member 200, at least one traction member 300, at least one matching member 410 and at least one first fastener 140. The mounting frame 100 is used to connect with the mounting surface, the driving member 200 is arranged on the mounting frame 100 and connected with the traction member 300, the matching member 410 is used to connect with the target part, and the matching member 410 is connected with the driving member 200 through the traction member 300.

[0046] The driving member 200 is configured to drive the traction member 300 to wind or stretch by rotation, so that the target member is driven to approach or move away from the mounting bracket 100 through the matching member 410 .

[0047] The first fastener 140 is configured to connect the mounting bracket 100 and the target part when the target part moves to a preset position.

[0048] It is understandable that 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 hanging device, or a furniture device such as a wall cabinet, a cabinet, a bookshelf or a hanging TV bracket. In this application, the ceiling machine body 400 is taken as an example. The installation surface can be located indoors, such as a ceiling wall, a suspended ceiling, etc., or outdoors.

[0049] The mounting frame 100 is connected to the mounting surface, and may be fixedly connected to the mounting surface via expansion bolts, or connected to a connecting structure on the mounting surface via bolts, and the present application does not impose any limitation on this.

[0050] In this way, the mounting frame 100 can be fixedly set on the mounting surface, and a driving member 200 is set on the mounting frame 100. The driving member 200 is connected to the matching member 410 set on the ceiling machine body 400 through the traction member 300, so that the driving member 200 drives the traction member 300 to drive the ceiling machine body 400 to rise, so that the ceiling machine body 400 moves close to the mounting frame 100, or the driving member 200 drives the traction member 300 to drive the ceiling machine body 400 to descend, so that the ceiling machine body 400 moves away from the mounting frame 100, thereby realizing the lifting and lowering of the ceiling machine body 400 through the driving member 200, the traction member 300 and the matching member. There is no need for the operator to lift the ceiling machine body 400 close to the mounting surface when the ceiling machine is installed, which makes the installation of the ceiling machine more time-saving and labor-saving.

[0051] In addition, a first fastener 140 is also provided, and the ceiling machine body 400 can be connected to the first fastener 140 through a matching piece 410. In a specific implementation, the first fastener 140 can be a bolt, a latch or a snap-on piece, etc., and this application does not impose any restrictions on this. When the ceiling machine body 400 is driven by the driving member 200 and the traction member 300 to rise to a preset position at the mounting frame 100, for example, when the corresponding connection portion on the mounting frame 100 is aligned with the matching piece 410 on the ceiling machine body 400, the ceiling machine body 400 reaches the preset position. At this time, the mounting frame 100 can be connected to the matching piece 410 through the first fastener 140, so that the ceiling machine body 400 can be fixedly connected to the mounting surface through the mounting frame 100, the first fastener 140 and the matching piece 410. If the main body 400 of the ceiling machine needs to be kept in this position for a long time, and there is no need to lift the main body 400 of the ceiling machine, the fixed position of the ceiling machine can be maintained only by the first fastener 140 and the mounting frame 100, so as to remove the load of the main body 400 of the ceiling machine on the traction member 300 and the driving member 200, and avoid the traction member 300 and the driving member 200 from being damaged and ineffective due to long-term load. And when the driving member 200 or the traction member 300 needs to be repaired and cleaned due to other reasons, such as rusting due to water or dust adhesion, the driving member 200 and the traction member 300 can also be directly removed, reducing the difficulty of repairing and cleaning the traction member 300 and the driving member 200.

[0052] In the specific implementation, four traction members 300 are provided, and the four traction members 300 are respectively connected to the four top corners of the ceiling machine body 400. Similarly, four first fasteners 140 and four matching members 410 are provided to connect with the ceiling machine body 400 to make the installation of the ceiling machine body 400 more stable.

[0053] Therefore, the lifting device provided in the embodiment of the present application is provided with a driving member 200 on the mounting frame 100 located on the mounting surface, and a traction member 300 is connected to the driving member 200, and the traction member 300 is connected to the matching member 410 provided on the ceiling machine body 400, so that the traction member 300 is driven by the driving member 200 to drive the ceiling machine body 400 to rise close to the mounting frame 100 or descend away from the mounting frame 100, and when the ceiling machine body 400 rises to a preset position, the ceiling machine body 400 can be connected to the mounting frame 100 by fasteners to achieve the installation of the ceiling machine body 400.

[0054] When the ceiling machine body 400 is connected to the mounting frame 100 by fasteners, the driving member 200 and the traction member 300 can be prevented from being in a load state for a long time, thereby extending the service life of the driving member 200 and the traction member 300, and preventing the ceiling machine from falling due to failure of the driving member 200 and the traction member 300, making the installation of the ceiling machine more stable and reliable.

[0055] In a specific implementation, the driving member 200 can be a driving motor arranged on the mounting frame 100, or a manual winder, etc. For example, in this embodiment and subsequent embodiments, a driving motor is arranged as the driving member 200. The driving motor generally includes a motor body and a motor cover 210 arranged on the motor body. The motor cover 210 protects the inside of the motor body to prevent dust from entering the inside of the motor body and affecting the operation effect of the motor. A winding portion 220 is arranged at the output end of the driving motor, and the output end can drive the winding portion 220 to rotate clockwise or counterclockwise around its own axis direction.

[0056] The traction member 300 can be a steel wire rope, or other ropes with sufficient strength and relatively softness that can be wound on the winding part 220. The winding part 220 is provided with an annular winding groove. One end of the traction member 300 is wound on the winding groove to be connected to the driving member 200, and the other end is connected to the ceiling machine body 400. Specifically, it can be clamped by the clamping structure provided on the ceiling machine body 400, or it can be hung or clamped with the ceiling machine body 400 through other stoppers. This application does not limit this. This application does not limit the specific structural settings of the driving member and the traction member.

[0057] Reference Figure 2 As shown, in this embodiment, the mating part 410 includes a first mating portion 411 and a second mating portion 412 arranged on the first mating portion 411, the second mating portion 412 is used to connect with the target part, the traction part 300 is connected to the second mating portion 412, and the first mating portion 411 is connected to the mounting frame 100 through the first fastener 140.

[0058] A matching piece 410 is provided on the ceiling machine body 400, and the matching piece 410 includes a first matching portion 411 and a second matching portion 412 connected to each other, wherein the second matching portion 412 is connected to the traction piece 300. A through hole is provided on the second matching portion 412, and the traction piece 300 can pass through the through hole and then be tied by itself to stop with the through hole of the second matching portion 412, or a stop block is provided at one end of the traction piece 300 passing through the through hole on the second matching portion 412, so that the stop block abuts against the second matching portion 412, and the present application does not limit this.

[0059] By providing a first matching portion 411 and a second matching portion 412 connected to each other to form a matching piece 410, the mounting frame 100 and the traction member 300 are both connected to the ceiling machine body 400 through the matching piece 410, which can make the connection between the ceiling machine body 400 and the lifting device simpler, more compact and easier to implement.

[0060] In some embodiments, reference 1 to Figure 4 As shown, the mounting frame 100 includes a mounting member 110 and at least one connecting member 120 arranged on the mounting member 110, the connecting member 120 is used to connect to the mounting surface, the driving member 200 is arranged on the mounting member 110, and the connecting member 120 is connected to the first matching portion 411 through a first fastener 140.

[0061] It can be understood that the installation frame 100 is composed of a mounting member 110 and a connecting member 120, so that the structure of the installation frame 100 can be more compact. The connecting member 120 and the installation member 110 can be connected by bolts or welding, and the present application does not impose any restrictions on this. The connecting member 120 is connected to the matching member 410 on the ceiling machine body 400 through the first fastener 140, and is specifically connected to the first matching portion 411. In order to make the force applied by the mounting frame 100 to the ceiling machine body 400 more balanced and stable, in this embodiment, two connecting members 120 are symmetrically arranged at both ends of the extension direction of the mounting member 110. At least two mounting holes 1211 are respectively provided on the two connecting members 120, and the expansion bolts are fixedly connected to the mounting surface through the mounting holes 1211.

[0062] In other embodiments, one connecting member 120 or more connecting members 120 may be provided to be connected to other corresponding applicable target members, and a mounting hole 1211 may also be opened on the mounting member 110 so that the mounting member 110 is connected to the mounting surface through an expansion bolt, or mounting holes 1211 may be opened on both the mounting member 110 and the connecting member 120, and the present application does not impose any restrictions on this.

[0063] In some embodiments, reference Figure 2 and Figure 4As shown, the connecting member 120 includes a first connecting section 121 and a second connecting section 122 arranged on the first connecting section 121, the first connecting section 121 is connected to the mounting frame 100, the second connecting section 122 is located on one side of the extension direction of the mounting member 110, and the second connecting section 122 is connected to the first matching portion 411 along the extension direction of the mounting member 110.

[0064] It can be understood that the second connecting section 122 is bent relative to the first connecting section 121, so that the first connecting section 121 can be easily connected to the mounting frame 100 and the mounting surface, and the second connecting section 122 is bent and relatively located on one side of the extension direction of the mounting member 110, so that the second connecting section 122 can be located on the side of the ceiling machine body 400, so as to facilitate the first fastener 140 to be connected to the ceiling machine body 400 from the side of the ceiling machine body 400 through the second connecting section 122.

[0065] Further, see Figure 2 and Figure 4 As shown, the second connecting section 122 is provided with a connecting hole 1221, and the first matching portion 411 is provided with a matching hole. When the target part moves to the preset position, the connecting hole 1221 is aligned with the matching hole, and the first fastener 140 is inserted into the connecting hole 1221 and the matching hole to connect the second connecting section 122 and the first matching portion 411. Such a configuration can make the installation of the first fastener 140 more convenient and quick, and make the structure of the connecting member 120 relatively simple.

[0066] In some other embodiments, reference Figure 1 , Figure 2 and Figure 6 As shown, the mounting frame 100 also includes at least one guide member 130, which is connected to the connecting member 120, and the guide member 130 is connected to the side of the connecting member 120 facing the mounting member 110. The traction member 300 is wrapped around the guide member 130 and passes through the guide member 130 to be connected to the second matching portion 412.

[0067] It can be understood that since the driving member 200 is located at the center of the mounting frame 100, if the traction member 300 wound on the driving member 200 is directly connected to the matching member 410 at the top corner position of the ceiling machine body 400, the traction member 300 will be tilted in the vertical direction, affecting the maximum lifting stroke of the driving member 200 and the traction member 300 on the ceiling machine body 400, and it is not convenient for the traction member 300 to stably lift the ceiling machine body 400. By arranging a guide member 130 on the side of the connecting member 120 facing the mounting member 110, the traction member 300 is connected to the ceiling machine body 400 after passing through the guide member 130, and the traction member 300 can be guided by the guide member 130 to first be wound on the traction member 300 in the horizontal direction, and then connected to the matching member 410 in the vertical direction, effectively improving the lifting stroke of the traction member 300, and ensuring that the posture of the ceiling machine body 400 is relatively stable during the lifting process.

[0068] In specific settings, the number of guide members 130 is consistent with that of the traction member 300 , and the specific position on the connecting member 120 can be determined according to the connection position between the traction member 300 and the target member.

[0069] Among them, refer to Figure 2 and Figure 6 As shown, the guide member 130 includes a guide column 131, a first stop portion 132, a second stop portion 133 and a first limiting portion 134. The guide column 131 is connected to the connecting member 120. The first stop portion 132 and the second stop portion 133 are arranged on the guide column 131 at intervals along the extension direction of the guide column 131. The first limiting portion 134 is arranged on the side of the first stop portion 132 facing the second stop portion 133.

[0070] The pulling member 300 is disposed around a portion of the guide column 131 between the first stopping portion 132 and the second stopping portion 133 via the first limiting portion 134 , and passes through the first stopping portion 132 to be connected to the second matching portion 412 .

[0071] In this way, one end of the guide column 131 can be connected to the first connecting section 121, so that the extension direction of the guide column 131 is consistent with the extension direction of the second connecting section 122, so that the structure of the mounting frame 100 is more compact, and it is convenient for the traction member 300 to be wound around the guide column 131 in the horizontal direction. The first stopper 132 and the second stopper 133 are arranged at intervals in the extension direction of the guide column 131. The first stopper 132 and the second stopper 133 can be specifically a stopper, so that the first stopper 132 is connected to one end of the guide column 131 away from the first connecting section, and the second stopper 133 is located between the first stopper 132 and the first connecting section 121, so that the first stopper 132 and the second stopper 133 can be used to form a winding space on the guide column 131.

[0072] The first stopper 132 is provided with a first limiting portion 134 located on one side of the guide post 131, and the traction member 300 can be stably limited in the winding space by the first limiting portion 134 to prevent the traction member 300 from escaping from the winding space. A gap is left between the first limiting portion 134 and the second limiting portion 133, and the distance between the first limiting portion 134 and the guide post 131 can be controlled so that the traction member 300 can only enter the winding space through the gap between the first limiting portion 134 and the second limiting portion 133, and be wound and arranged along the extension direction of the guide post 131.

[0073] Further, see Figure 2 and Figure 6 As shown, the guide member 130 also includes a second limiting portion 135, which is arranged on the side of the first stopping portion 132 facing the second stopping portion 133, and a through hole 1321 corresponding to the second limiting portion 135 is arranged on the first stopping portion 132. The traction member 300 passes through the first stopping portion 132 via the second limiting portion 135 and the through hole 1321 in sequence.

[0074] A second limiting portion 135 is provided on the first stopper 132 opposite to the first limiting portion 134. The second limiting portion 135 is located on the other side of the guide column 131. The second limiting portion 135 can only accommodate a single strand of the traction member 300 to pass through, thereby preventing the traction member 300 from being entangled on the guide column 131. After the traction member 300 passes through the second limiting portion 135, it can also change direction through the through hole 1321 on the first stopper 132 to connect with the first matching portion 411 of the matching member 410. Such a configuration can make the guide member 130 simple in structure and have good wire management and guiding functions, so that the traction member 300 can smoothly drive the ceiling machine body 400 to rise and fall.

[0075] In other embodiments, the guide member 130 may also be configured as a guide ring or other structure having guiding and reversing functions, and the present application does not impose any limitation on this.

[0076] Among them, refer to Figure 1 , Figure 3 and Figure 4 As shown, the mounting member 110 has an avoidance bending section 111, which forms a receiving groove. The receiving groove has an assembly hole 112. The driving member 200 is inserted into the receiving groove through the assembly hole 112 and is detachably connected to the receiving groove. The traction member 300 is wrapped around the part of the driving member 200 located outside the receiving groove.

[0077] It can be understood that by providing an avoidance bending section 111 on the mounting member 110, the avoidance bending section 111 can be used to form a receiving groove located on one side of the mounting member 110. After the mounting member 110 is connected to the mounting surface, the receiving groove can be enclosed with the mounting surface to form an installation space for installing the driving member 200, so that the lifting device structure is compact.

[0078] In order to facilitate the driving member 200 to drive the traction member 300 to wind or stretch in the accommodating groove, an assembly hole 112 can be opened on the avoidance bending section 111, so that the winding portion 220 of the driving member 200 is located outside the accommodating groove through the assembly hole 112, on the side of the avoidance bending section 111 away from the installation surface, so as to be wound and connected with the traction member 300 from this side.

[0079] In addition, in order to facilitate the detachable connection between the driving member 200 and the avoidance bending section 111, an opening can be set on one side of the assembly hole 112 so that the assembly hole 112 is connected to the edge of the avoidance bending section 111 through the opening, so that the driving member 200 can enter the assembly hole 112 through the opening from the opening side of the avoidance bending section 111 along the horizontal direction.

[0080] In some embodiments, reference Figures 3 to 5 As shown, the lifting device provided in the embodiment of the present application also includes at least one second fastener, and at least one first mounting portion 113 corresponding to the accommodating groove is provided on the mounting member 110, and at least one second mounting portion 221 corresponding to the first mounting portion 113 is provided on the partial driving member 200 located in the accommodating groove, and the first mounting portion 113 and the second mounting portion 221 are detachably connected by a second fastener.

[0081] By providing the first mounting portion 113 and the second mounting portion 221, the first mounting portion 113 and the second mounting portion 221 are detachably connected via the second fastener, thereby facilitating a stable connection between the driving member 200 and the avoidance bending section 111, and also making it more convenient and quick to remove the driving member 200 from the avoidance bending section 111.

[0082] Two first mounting parts 113 are respectively arranged on both sides of the extension direction of the avoidance bending section 111, and a through hole is opened on each first mounting part 113. Similarly, four second mounting parts 221 are correspondingly arranged on the motor cover 210 of the driving member 200, and through holes are also opened on the second mounting parts 221, so that the second fastener can be set as a bolt, a plug pin or a snap-on part, etc., so that the second fastener is sequentially penetrated through the through hole on the second mounting part 221 and the first mounting part 113, so that the driving member 200 and the avoidance bending section 111 can be detachably connected.

[0083] In specific implementation, the present application does not limit the specific structure and number of the first mounting portion 113 and the second mounting portion 221 .

[0084] An embodiment of the present application further provides a ceiling machine, comprising a ceiling machine body 400 and a hanging device in any of the above embodiments, wherein the ceiling machine body 400 is connected to the hanging device.

[0085] The hoisting device has been described in detail in the above embodiments and will not be described again here.

[0086] The present application provides a ceiling machine, which is provided with a lifting device. The lifting device is provided with a driving member 200 on a mounting frame 100 located on a mounting surface, a traction member 300 is connected to the driving member 200, and the traction member 300 is connected to an assembly member 410 on a target part such as a ceiling machine body 400. The driving member 200 drives the traction member 300 to drive the ceiling machine body 400 to rise close to the mounting frame 100 or to descend away from the mounting frame 100. When the ceiling machine body 400 rises to a preset position, the ceiling machine body 400 can be connected to the mounting frame 100 by fasteners to achieve the installation of the ceiling machine body 400.

[0087] When the mating part 410 on the ceiling machine body 400 is connected to the mounting frame 100 through the first fastener 140, the driving member 200 and the traction member 300 can be prevented from being in a load state for a long time, thereby extending the service life of the driving member 200 and the traction member 300, avoiding the failure of the driving member 200 and the traction member 300 that causes the ceiling machine to fall, and making the installation of the ceiling machine more stable and reliable.
