[0039] In the related art, a sound system usually adopts two sets of connecting assemblies, one set as a wall-locking connecting assembly and the other set as a hanging connecting assembly. When wall-locking, one end of the wall-locking connecting assembly is connected with a wall surface and the other end is connected with the back surface of a sound box. When hanging, one end of the hanging connecting assembly is connected with a ceiling and the other end is connected with the top surface of the sound box. The two sets of connecting assemblies are mutually split and have no association, thereby making it necessary to spend more time and resources in design and increasing the workload in the design stage. In production, two different assemblies mean that more materials and different manufacturing processes are needed, which directly increases the production cost.

[0040] To this end, the inventors of the present application have tried to design the part connected with the sound box in the hanging connection assembly and the part connected with the sound box in the lock wall connection assembly as a common part, so that the part can be used to connect with the sound box in both the hanging and the lock wall installation, thereby reducing the cost. Moreover, when the sound box that has been hung is replaced by a lock wall installation, or the sound box that has been installed by a lock wall is replaced by a hanging, the common part can be used without disassembly and assembly, thereby reducing the disassembly and assembly operations and greatly improving the installation efficiency.

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application.

[0042] Please refer to Figures 1 to 3 As shown in the drawings, the present application provides a mounting bracket, which can at least include a connecting unit and an attachment 100, wherein the attachment 100 is used to connect with a to-be-installed device 400, and the connecting unit is connected with the to-be-installed device 400 through the attachment 100, so as to lock wall install or hang the to-be-installed device 400. It should be pointed out that the to-be-installed device 400 defined in the present application can be an audio device such as a sound box, a display device, a video camera, a projector or other devices that can be installed on a lock wall or hung.

[0043] Specifically, in an implementable embodiment, the attachment 100 has a first section 110 and a second section 120, the first section 110 and the second section 120 are connected, and the first section 110 and the second section 120 are arranged at an angle, that is, the first section 110 and the second section 120 are respectively located on different planes, so that when the attachment 100 is connected with the to-be-installed device 400, the first section 110 can be arranged on the top surface of the to-be-installed device 400 for hanging connection, and the second section 120 can be arranged on the back surface of the to-be-installed device 400 for lock wall installation connection. In actual application, the angle between the first section 110 and the second section 120 can be set according to the angle of the back surface and the top surface of the to-be-installed device 400, for example, the angle between the first section 110 and the second section 120 can be 80°, 85°, 90°, 95° or 100°, etc.

[0044] In the embodiment, the connecting unit can be the first connecting component 200 for hoisting or the second connecting component 300 for wall locking installation, and the first section 110 is provided with a connecting hole 111 and the second section 120 is provided with a connecting part 121. When the connecting unit is the first connecting component 200, the first connecting component 200 is connected with the connecting hole 111, so that the to-be-installed equipment 400 can be hoisted on the top surface of the installation space (for example, the ceiling in the room) through the attachment 100 and the first connecting component 200, thereby realizing hoisting of the to-be-installed equipment 400. When the connecting unit is the second connecting component 300, the second connecting component 300 is connected with the connecting part 121, so that the to-be-installed equipment 400 can be installed on the side surface of the installation space (for example, the wall surface in the room) through the attachment 100 and the second connecting component 300, thereby realizing wall locking installation of the to-be-installed equipment 400.

[0045] It is worth mentioning that, whether in hoisting the to-be-installed equipment 400 or in wall locking installation of the to-be-installed equipment 400, the attachment 100 is connected with the to-be-installed equipment 400. In other words, the attachment 100 and the first connecting component 200 jointly constitute a hoisting connecting assembly, and the attachment 100 and the second connecting component 300 jointly constitute a wall locking connecting assembly, and the attachment 100 is a common part in the hoisting connecting assembly and the wall locking connecting assembly, so that the attachment 100 can be used for hoisting and wall locking installation, thereby optimizing the design and production process and reducing the production cost. It can be understood that, when the to-be-installed equipment 400 that has been hoisted is replaced by wall locking installation, or the to-be-installed equipment 400 that has been wall locking installed is replaced by hoisting, the attachment 100 does not need to be disassembled, thereby reducing one-time disassembly operation and one-time installation operation, and greatly improving the installation efficiency.

[0046] The above-mentioned attachment 100 can be connected with the to-be-installed equipment 400 only through the first section 110, the attachment 100 can also be connected with the to-be-installed equipment 400 only through the second section 120, or the attachment 100 can be connected with the to-be-installed equipment 400 through the first section 110 and the second section 120 at the same time, which is not limited here.

[0047] Taking an example that the attachment 100 is connected with the to-be-installed equipment 400 only through the second section 120, as shown in Figure 3 and Figure 4 The second section 120 can be provided with at least two through holes 122, and correspondingly, the back surface of the to-be-installed equipment 400 can be provided with first locking holes corresponding to the through holes 122. The fastener is screwed through the through holes 122 and the first locking holes, so as to connect the second section 120 with the to-be-installed equipment 400, thereby realizing connection of the attachment 100 with the to-be-installed equipment 400 through the second section 120.

[0048] The specific structure of the first connecting component 200 is as followsFigure 4 And Figure 5 As shown in FIGS. 1 and 2, in an implementable embodiment, the first connecting component 200 comprises a hoisting member 210 and a screw rod 220, wherein the screw rod 220 is arranged at the bottom of the hoisting member 210, and the hoisting member 210 is connected with the first section 110 through the screw rod 220 and the connecting hole 111. In this way, the connecting components with the same screw thread specification can be used as the first connecting component 200, so as to facilitate customization of different first connecting components 200 according to different use requirements, such as shape requirements or length requirements, and reduce production cost.

[0049] In actual application, the hoisting member 210 and the screw rod 220 can be designed integrally, or can be designed separately and then connected with each other. The hoisting member 210 can be a hoisting rod, a hoisting frame or other hoisting structure. The application preferably adopts the hoisting rod structure for the hoisting member 210, which is simple in structure and facilitates integral machining of the hoisting member 210 and the screw rod 220, thereby simplifying the production process.

[0050] Regarding the specific structure of the connecting hole 111, the application provides two implementable embodiments for reference.

[0051] Embodiment one, the connecting hole 111 can be a through hole. The screw rod 220 can be connected with a nut through the connecting hole 111, so as to clamp the first section 110 between the nut and the hoisting member 210, thereby achieving the connection between the hoisting member 210 and the first section 110.

[0052] Embodiment two, the connecting hole 111 can be a threaded hole. In an implementable embodiment, the screw rod 220 can be threadedly connected with the connecting hole 111 only, so as to achieve the connection between the hoisting member 210 and the first section 110.

[0053] In another optional embodiment, as shown in FIGS. 3 and 4, the screw rod 220 can be threadedly connected with the connecting hole 111 and the to-be-installed equipment 400 through the connecting hole 111, so as to achieve the connection between the hoisting member 210 and the first section 110. Figure 1 And Figure 4 In this way, the screw rod 220 is threadedly connected with the connecting hole 111 and the to-be-installed equipment 400 at the same time, which can effectively improve the safety of hoisting the to-be-installed equipment 400 and avoid the risk of accidental falling due to damage of single connection.

[0054] In actual application, the top surface of the to-be-installed equipment 400 is provided with a second locking hole corresponding to the connecting hole 111, and the inner thread screw thread specification of the second locking hole is the same as that of the connecting hole 111, so that the screw rod 220 can be threadedly connected with the connecting hole 111 and the to-be-installed equipment 400 at the same time.

[0055] Regarding the specific structure of the second connecting component 300, as shown in FIGS. 5 and 6,Figure 2 , Figure 6 and Figure 7 As shown, in one feasible embodiment, the second connecting member 300 may include at least a wall-locking member 310, which is used to be installed on the side of the installation space (e.g., the wall in the room). The connecting part 121 can be directly connected to the wall-locking member 310 to realize the wall-locking installation of the device 400 to be installed.

[0056] In practical applications, the connecting part 121 can be fixedly connected to the wall-locking component 310. The connecting part 121 can also be flexibly connected to the wall-locking component 310, thereby adjusting the connection structure between the connecting part 121 and the wall-locking component 310, so that the device 400 to be installed can rotate up and down or left and right relative to the wall-locking component 310.

[0057] In another optional embodiment, the second connecting component 300 may include a locking member 310 and an adapter 320, wherein the locking member 310 can be connected to the connecting portion 121 via the adapter 320. Specifically, one end of the adapter 320 is connected to the locking member 310 along the first axis L1 via a first fastening assembly 330, and the other end of the adapter 320 is connected to the connecting portion 121 along the second axis L2 via a second fastening assembly 340, wherein the first axis L1 and the second axis L2 are perpendicular.

[0058] In this way, by loosening the first fastening component 330, the connecting part 121 can be adjusted to rotate around the first axis L1, that is, the device to be installed 400 can be adjusted to rotate around the first axis L1. And by loosening the second fastening component 340, the connecting part 121 can be adjusted to rotate around the second axis L1, that is, the device to be installed 400 can be adjusted to rotate around the second axis L2. Thus, multi-directional adjustment operations can be achieved to meet different installation requirements.

[0059] In practical applications, the first axis L1 can be parallel to one of the vertical and horizontal directions, and correspondingly, the second axis L2 can be parallel to the other of the vertical and horizontal directions. In this way, the equipment to be installed 400 can be adjusted in the up-down and left-right directions.

[0060] like Figure 6 and Figure 7 As shown, in one feasible embodiment, the wall-locking component 310 may have a wall-locking portion 311 and a lug portion 312. The wall-locking portion 311 is used for mounting on the side of the installation space (e.g., a wall in a room), and the lug portion 312 is located on the side of the wall-locking portion 311 adjacent to the adapter 320. The lug portion 312 is connected to the adapter 320 along the first axis L1 via a first fastening assembly 330. Thus, the wall-locking component 310 is effectively divided into two parts: one part for connecting to the wall and the other part for connecting to the adapter 320. These two parts do not interfere with each other, facilitating installation.

[0061] In practical applications, the lock wall part 311 can be configured as a plate-shaped structure, and at least two through holes can be formed on the lock wall part 311. The lock wall part 311 can be fixed on the wall surface by expansion screws passing through the through holes on the lock wall part 311, that is, during installation, an expansion sleeve can be reserved in the wall surface, and then the screw is connected with the expansion sleeve by passing through the through hole on the lock wall part 311, so as to fix the lock wall part 311 on the wall surface.

[0062] For the specific structure of the first fastening assembly 330, please refer to Figure 6 and Figure 7 In an implementable embodiment, the first fastening assembly 330 can include a first bolt 331 and a first nut 332. The lug part 312 and one end of the adapter 320 are each provided with a through hole extending along the first axis L1, and one end of the first bolt 331 is connected with the first nut 332 by passing through the through hole of the lug part 312 and the through hole of one end of the adapter 320. In this way, by screwing the first bolt 331 and / or the first nut 332, the first nut 332 can be moved towards the head of the first bolt 331 to achieve compression and fixation of the adapter 320 and the lug part 312, or the first nut 332 can be moved away from the head of the first bolt 331 to loosen the adapter 320 and the lug part 312, so as to facilitate switching between the compression and fixation state and the loosening state of the lug part 312 and the adapter 320.

[0063] For the specific structure of the second fastening assembly 340, in an implementable embodiment, the second fastening assembly 340 includes a second bolt 341 and a second nut 342. The connecting part 121 and the other end of the adapter 320 are each provided with a through hole extending along the second axis (L2), and one end of the second bolt 341 is connected with the second nut 342 by passing through the through hole of the connecting part 121 and the through hole of the other end of the adapter 320. In this way, by screwing the second bolt 341 and / or the second nut 342, the second nut 342 can be moved towards the head of the second bolt 341 to achieve compression and fixation of the adapter 320 and the connecting part 121, or the second nut 342 can be moved away from the head of the second bolt 341 to loosen the adapter 320 and the connecting part 121, so as to facilitate switching between the compression and fixation state and the loosening state of the lug part 312 and the adapter 320.

[0064] In an implementable embodiment, a friction member 350 can be arranged between one end of the adapter 320 and the lug portion 312. In this way, when the first fastening assembly 330 is used to press and fix the adapter 320 and the lug portion 312, compared with the case where the adapter 320 directly contacts the lug portion 312, the adapter 320 and the lug portion 312 respectively contact the friction member 350, so that the friction force between the adapter 320 and the lug portion 312 can be increased, and relative rotation between the adapter 320 and the lug portion 312 during fixing can be avoided, and the stability during fixing can be improved.

[0065] Preferably, the friction member 350 can have elastic deformation capability, so that when the first fastening assembly 330 is loosened, the friction member 350 can expand so that the friction member 350 still abuts against the adapter 320 and the lug portion 312, so that a certain holding force or damping exists between the friction member 350, the adapter 320 and the lug portion 312, so as to facilitate adjustment operation. In actual application, the friction member 350 can be a rubber gasket or other elastic ring.

[0066] Similarly, the other end of the adapter 320 and the connecting portion 121 can also be provided with a friction member 350.
