DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] As described in the background technology, when installing the ceiling machine, it is necessary to pre-open bolt holes on the installation surface, connect each hanging foot to the installation surface through expansion bolts, and then the operator lifts the ceiling machine, connects the ceiling machine to the hanging foot on one side of the ceiling machine, and maintains the current lifting state, and then moves the hanging foot on the other side of the ceiling machine, connects the remaining hanging foot to the ceiling machine, and completes the installation.

[0040] However, when installing the ceiling-mounted machine in this operation mode, the operator needs to support the ceiling-mounted machine for a long time during the operation, which is inconvenient for the installation operation of the ceiling-mounted machine. Moreover, during the operation, there is a risk that the ceiling-mounted machine may break out of the hanging feet or even fall off, and the installation safety is poor.

[0041] In order to overcome the defects in the prior art, the double-hook hoisting device and the ceiling-mounted machine provided by the embodiments of the present application. The double-hook hoisting device is connected to the installation surface by setting a bracket. A first hook assembly and a second hook assembly are rotatably arranged on the bracket, and a support member is connected to the target member, so that the support member is connected to the bracket through the common support of the first hook assembly and the second hook assembly to complete the hoisting of the target member. When hoisting the target member, only need to move the support member on the target member towards the bracket on the installation surface. When the support member moves to the preset position, the first hook assembly rotates and is engaged with the second hook assembly. The first hook assembly and the second hook assembly cooperate with each other to jointly support the support member, so that the support member is hooked to the bracket to complete the hoisting operation. The hoisting operation process does not require long-term lifting of the target member for operation, and a knocking sound will be emitted when the hook member contacts the support member, which is convenient for indicating whether the target member is installed in place, making the installation operation of the target member convenient, fast and reliable.

[0042] The content of the present invention will be described in detail below with reference to the drawings, so that those skilled in the art can understand the content of the present invention more clearly and in detail.

[0043] Refer to Figures 1 to 5 As shown, the embodiments of the present application provide a double-hook hoisting device, including a bracket 100, a first hook assembly 200, a second hook assembly 300 and a support member 400. The bracket 100 is used to be connected to the installation surface. Both the first hook assembly 200 and the second hook assembly 300 are rotatably connected to the bracket 100. The support member 400 is used to be connected to the target member 700;

[0044] The first hook assembly 200 and the second hook assembly 300 are in contact with each other. The support member 400 moves towards the second hook assembly 300 to drive the second hook assembly 300 to rotate. When the support member 400 moves to the preset position, the first hook assembly 200 and the second hook assembly 300 are separated from the contact, and the first hook assembly 200 rotates to be engaged with the second hook assembly 300, and the first hook assembly 200 and the second hook assembly 300 jointly support the support member 400.

[0045] It can be understood that the bracket 100 is connected to the installation surface. Specifically, connection holes can be opened on the bracket 100, and the bracket 100 can be pre-stably installed on the installation surface through the hanging feet by using expansion bolts, or it can be fixedly connected to the corresponding connection frame and other structures on the installation surface. The present application does not limit this.

[0046] A first hook assembly 200 and a second hook assembly 300 are rotatably arranged on the bracket 100. Both the first hook assembly 200 and the second hook assembly 300 can be located on the side of the bracket 100 away from the mounting surface, and the first hook assembly 200 and the second hook assembly 300 are arranged oppositely, so that the rotation directions between the first hook assembly 200 and the second hook assembly 300 are opposite, so as to enable the first hook assembly 200 and the second hook assembly 300 to cooperate with each other. In addition, a support member 400 is also provided. The support member 400 is arranged on the target member 700, so that the target member 700 is connected to the hook member through the support member 400.

[0047] In this embodiment, the target member 700 is Figure 1 the ceiling-mounted machine main body shown in the figure. The support member 400 of the double-hook hoisting device is specifically connected to the ceiling-mounted machine main body, so as to realize hoisting the ceiling-mounted machine main body on the mounting surface through the hanging connection of the support member 400 and the hook member.

[0048] In other realizable embodiments, the target member 700 can also be electrical equipment such as a ceiling fan, a chandelier or a projector installed on the mounting surface in a hoisting form, or furniture devices such as a wall cabinet, a cabinet, a bookshelf or a hanging TV, or indoor ventilation ducts, etc. And the mounting surface can be located indoors, such as a ceiling wall, a ceiling, etc., or can be located outdoors.

[0049] When the target member 700 is hoisted, only the support member 400 on the target member 700 needs to be moved towards the bracket 100 on the mounting surface, so that the support member 400 approaches the first hook assembly 200 and the second hook assembly 300 that are in mutual contact until the support member 400 abuts against the second hook assembly 300. When the support member 400 continues to move towards the bracket 100, it can drive the second hook assembly 300 to rotate relative to the bracket 100. When the second hook assembly 300 rotates, the parts of the second hook assembly 300 that abut against the first hook assembly 200 slide relative to each other to ensure that the two always abut. When the support member 400 moves to a preset position, the parts of the second hook assembly 300 that abut against the first hook assembly 200 are disengaged from the abutment. The first hook assembly 200 loses the limit of the second hook assembly 300 and will rotate towards the second hook assembly 300 by itself to be clamped with another part of the second hook assembly 300. After the first hook assembly 200 and the second hook assembly 300 are clamped, they can jointly support the support member 400, so that the support member 400 is stably hung on the first hook assembly 200 and the second hook assembly 300. When the first hook assembly 200 rotates to be hooked with the second hook assembly 300, the first hook assembly 200 will collide with the second hook assembly 300 and generate a knocking sound. The operator can judge whether the support member 400 is installed in place and whether the supporting effect of the first hook assembly 200 and the second hook assembly 300 on the support member 400 is stable and reliable through the knocking sound.

[0050] Therefore, the double-hook lifting device provided by the embodiments of the present application is connected to the installation surface by setting the bracket 100. The first hook assembly 200 and the second hook assembly 300 are rotatably arranged on the bracket 100, and the support member 400 is connected to the target member 700, so that the support member 400 is supported by the first hook assembly 200 and the second hook assembly 300 together to be connected to the bracket 100, completing the lifting of the target member 700.

[0051] When lifting the target member 700, only the support member 400 on the target member 700 needs to be moved towards the bracket 100 on the installation surface. When the support member 400 moves to the preset position, the first hook assembly 200 rotates and is clamped with the second hook assembly 300. The first hook assembly 200 and the second hook assembly 300 cooperate with each other to jointly support the support member 400, so that the support member 400 is hooked to the bracket 100, completing the lifting operation.

[0052] During the lifting operation process, there is no need to hold the target member 700 for a long time for operation, and a knocking sound will be emitted when the hook member contacts the support member 400, which is convenient for indicating whether the target member 700 is installed in place, making the installation operation of the target member 700 convenient, fast and reliable.

[0053] In some embodiments, as shown in Figures 2 to 5 the first hook assembly 200 includes a first hook member 210, a first elastic member 220 and a first connecting member 230. The first hook member 210 is rotatably connected to the bracket 100 through the first connecting member 230. The first elastic member 220 is arranged on the first connecting member 230 and is connected to the first hook member 210 and the bracket 100 to drive the first hook member 210 to rotate.

[0054] By setting the first connecting member 230, a stable rotational connection between the first hook member 210 and the bracket 100 can be achieved, and the overall structure of the hook assembly is simple, compact, stable and reliable. In specific implementation, the first connecting member 230 can be a rotating shaft, and a circular connection hole is opened on the bracket 100. The rotating shaft is rotatably inserted into the connection hole and connected to the first hook member 210.

[0055] The first elastic member 220 is also arranged on the first connecting member 230. The first elastic member 220 can be a torsion spring. The two ends of the torsion spring are respectively connected to the first hook member 210 and the bracket 100. In this way, when the first hook member 210 rotates away from the second hook assembly 300 and abuts against the second hook assembly 300, the torsion spring accumulates elastic potential energy. Subsequently, when the support member 400 moves to the preset position, the first hook member 210 loses the limit of the second hook assembly 300, so that the torsion spring releases the elastic potential energy and drives the first hook member 210 to be clamped with the second hook assembly 300, simplifying the installation operation of the target member 700.

[0056] In specific implementation, with reference to Figure 3 and Figure 5 As shown, the first hook member 210 includes a first connecting portion 211 and a first clamping portion 212 provided on the first connecting portion 211. The first connecting portion 211 is connected to the first connecting member 230, and a clamping notch 213 is provided on the first clamping portion 212;

[0057] The first clamping portion 212 abuts against the second hook assembly 300. When the support member 400 moves to a preset position, the first clamping portion 212 disengages from abutting against the second hook assembly 300 and is driven by the first elastic member 220 to rotate until the clamping notch 213 engages with the second hook assembly 300.

[0058] Such a setting can make the structure of the first hook member 210 simple and facilitate the engagement and disengagement with the second hook assembly 300. Among them, the first clamping portion 212 is driven by the first elastic member 220 to rotate around the first connecting portion 211, so that the clamping notch 213 on the first clamping portion 212 engages with the second hook assembly 300, without manual operation, and the operation is simple.

[0059] And the clamping notch 213 is arranged facing the second hook assembly 300, and the clamping notch 213 is inclined relative to the second hook assembly 300, which can ensure the reliability of the connection between the first clamping portion 212 and the second hook assembly 300, avoid disengagement, and ensure the stability and reliability of the support for the support member 400.

[0060] Furthermore, with reference to Figure 3 and Figure 5 As shown, the first hook member 210 further includes an operating portion 214 provided on the first clamping portion 212. The operating portion 214 drives the first connecting portion 211 to rotate in the reverse direction, so that the clamping notch 213 disengages from engaging with the second hook assembly 300.

[0061] It can be understood that by providing the operating portion 214, it is convenient for the operator to control the first clamping portion 212 to drive the first connecting portion 211 to rotate away from the second hook assembly 300 around the first connecting member 230 when the target member 700 needs to be removed from the double-hook lifting device, so that the clamping notch 213 on the first clamping portion 212 disengages from engaging with the second hook assembly 300, improving the flexibility and convenience of using the double-hook lifting device.

[0062] Specifically, the operating portion 214 can be set to fold relative to the first clamping portion 212 so that the operating portion 214 is perpendicular to the first clamping portion 212, which is convenient for the operator to apply force.

[0063] In some embodiments, with reference to Figures 1 to 5As shown, the second hook assembly 300 includes a second hook member 310 and a second connecting member 320. The second hook member 310 is rotatably connected to the bracket 100 through the second connecting member 320. The second hook member 310 has a connecting notch 314 for accommodating the support member 400.

[0064] Similarly, it can be understood that by setting the second connecting member 320, the stable rotational connection between the second hook member 310 and the bracket 100 can be achieved, and the overall structure of the hook assembly is simple, compact, stable and reliable. In a specific implementation, the second connecting member 320 can be the same rotating shaft as the first connecting member 230. A circular connecting hole is formed in the bracket 100, and the rotating shaft is rotatably inserted into the connecting hole and connected to the second hook member 310.

[0065] Wherein, the setting height of the second connecting member 320 can be the same as that of the first connecting member 230, and the first connecting member 230 and the second connecting member 320 are arranged at intervals, so that the first connecting member 230 and the second connecting member 320 can be stably hooked, neither interfering with each other nor being too far apart to result in poor hooking stability.

[0066] The second hook member 310 is provided with a connecting notch 314 for accommodating the support member 400. Therefore, when the support member 400 moves relative to the second hook assembly 300, it can enter the connecting notch 314, and drive the second hook assembly 300 to rotate within the connecting notch 314. On this basis, a part of the second hook member 310 on the side of the connecting notch 314 facing the first connecting member 230 can abut against the first hook member 210 to limit the rotation of the first hook member 210. When a part of the second hook member 310 on the side of the connecting notch 314 facing the first connecting member 230 rotates to disengage from the abutment with the first hook member 210, the first hook member 210 can rotate towards the second hook member 310 to engage with a part of the second hook member 310 on the side of the connecting notch 314 away from the first connecting member 230, so that the support member 400 is located within the connecting notch 314 and provides support for the support member 400, making the structure of the second hook member 310 simple and compact, and the support for the support member 400 more stable.

[0067] In a specific implementation, referring to Figure 3 and Figure 5 As shown, the second hook member 310 includes a second connecting portion 311, a second clamping portion 312 and an abutting portion 313. The second connecting portion 311 is connected to the second connecting member 320. The second clamping portion 312 and the abutting portion 313 are arranged at intervals on opposite sides of the second connecting portion 311, and a connecting notch 314 is formed between the second clamping portion 312 and the abutting portion 313;

[0068] The abutting portion 313 abuts against the first hook assembly 200, and the support member 400 drives the abutting portion 313 to move within the connection notch 314, so that the second connection portion 311 drives the second latching portion 312 to rotate;

[0069] When the support member 400 moves to a preset position, the abutting portion 313 disengages from the first hook assembly 200, the second latching portion 312 latches with the first hook assembly 200, and the second latching portion 312 and the first connection portion 211 jointly support the support member 400.

[0070] Wherein, the second latching portion 312 and the abutting portion 313 are arranged at intervals and are located on opposite sides of the second connection portion 311, so as to form a connection notch 314 between the second latching portion 312 and the abutting portion 313, simplifying the structure of the second hook member 310. The second connection portion 311 is connected to the bracket 100 through the second connecting member 320. The support member 400 moves towards the bracket 100 to enter the connection notch 314, and abuts against the abutting portion 313 within the connection notch 314, driving the second connection portion 311 to rotate around the second connecting member 320 through the abutting portion 313. The abutting portion 313 always abuts against the first latching portion 212 of the first hook member 210 during movement. After the support member 400 moves to the preset position, the abutting portion 313 disengages from the first latching portion 212, and the first elastic member 220 drives the first latching portion 212 to move towards the second latching portion 312, so that the latching notch 213 latches with the second latching portion 312. After the latching notch 213 latches with the second latching portion 312, the first hook member 210 and the second hook member 310 are tightly latched with each other and cannot move away from each other together. Therefore, the support member 400 within the connection notch 314 can be limited within the connection notch 314, providing stable support for the support member 400 and completing the installation of the target member 700.

[0071] In addition, in some embodiments, referring to Figure 3 and Figure 5 as shown, the second hook assembly 300 further includes a second elastic member 330. The second elastic member 330 is arranged on the second connecting member 320 and is connected to the second hook member 310 and the bracket 100 to drive the second hook member 310 to rotate in the reverse direction.

[0072] It can be understood that by arranging the second elastic member 330 on the second connecting member 320 and connecting the second elastic member 330 to the second hook member 310 and the bracket 100, when the first hook member 210 is driven by the operating portion 214 to move away from the second hook member 310, the second elastic member 330 can be used to drive the second hook member 310 to move away from the first hook member 210, facilitating the subsequent docking of the connection notch 314 of the second hook member 310 with the support member 400.

[0073] Specifically, the second elastic member 330 can be a torsion spring or a tension spring. The two ends of the second elastic member 330 are respectively connected to the second hook member 310 and the bracket 100. In this way, when the second hook member 310 rotates towards the first hook member 210, the second elastic member 330 accumulates elastic potential energy. Subsequently, when the first hook member 210 is disengaged from the second hook member 310, the second elastic member 330 releases the elastic potential energy and drives the second hook member 310 to rotate away from the first hook member 210.

[0074] In a possible implementation manner, the double-hook hoisting device provided by the embodiment of the present application further includes a first fastener 500 and a second fastener 600. The bracket 100 includes a first mounting portion 110 and a second mounting portion 120. The second mounting portion 120 is disposed on the first mounting portion 110. A first mounting hole 111 is provided on the first mounting portion 110. The first mounting hole 111 is used to connect to the mounting surface through the first fastener 500;

[0075] A second mounting hole 121 is provided on the second mounting portion 120. The second mounting hole 121 is used to connect to the target member 700 through the second fastener 600;
