[0027] Figure 1 This is an exemplary structural diagram of the mounting bracket before installation according to some embodiments of the present specification. Figure 2 is an exemplary structural diagram of the mounting bracket after installation according to some embodiments of this specification. Figure 1 and Figure 2 The following embodiments are understood, but the drawings are only for illustration of some of the embodiments and do not constitute a limitation of the embodiments.

[0028] In some embodiments, Figure 1 As shown, the mounting bracket 100 includes: a base plate 110 , a screw rod 120 , a wall hook 130 , a stopper 140 and a guide member 150 .

[0029] The bottom plate 110 refers to a component used to connect the mounting bracket 100 and the product, so that after the mounting bracket 100 is fixed to the ceiling of the wall, the product can also be fixed to the ceiling.

[0030] In some embodiments, the guide member 150 and the stopper 140 are fixedly connected to the bottom plate 110. In some embodiments, the guide member 150 and the stopper 140 can be a part of the bottom plate 110 and formed integrally with the bottom plate 110; or they can be separate parts fixed to the bottom plate 110 by screws, adhesives, etc.

[0031] In some embodiments, the shape of the bottom plate 110 may be square, round, or other special shapes. The material of the bottom plate 110 may be metal, plastic, or the like. For example, to save costs, the guide member 150 and the stop member 140 may be integrated with the bottom plate 110, and the material may be plastic, and may be formed by injection molding. For more information about the bottom plate 110, see below.

[0032] In some embodiments, the outer side of the screw 120 has a spiral feature, which can transmit force and moving parts. In some embodiments, the screw 120 is threadedly connected to the wall hook 130, slidably connected to the guide member 150, and fixedly connected to the stopper 140. The screw 120 may include a head, a tail, and a spiral portion.

[0033] In some embodiments, the head of the screw 120 is provided with a tool interface for rotating or driving the screw 120. For example, the head of the screw 120 is an internal hexagonal head, an external hexagonal head, an oval head cross slot, etc. The outer diameter of the head of the screw 120 is larger than the inner diameter of the through hole connecting the guide 150 and the screw 120, ensuring that the head of the screw 120 is outside the guide 150.

[0034] In some embodiments, the installer rotates the head of the screw rod 120 by means of a tool (such as a wrench or a screwdriver), and the rotation of the screw rod 120 drives the wall hook 130, and the wall hook 130 rotates with the rotation of the screw rod 120. The material of the screw rod 120 can be metal (such as carbon steel), hard plastic, etc. The tail of the screw rod 120 is fixedly connected to the stopper 140. For more information about the connection method, see below.

[0035] In some embodiments, the screw rod 120 may be a standard part or may be obtained by machining threads on a rod. In some embodiments, the screw rod 120 passes through the guide member 150, the wall hook 130 and the stopper 140 in sequence.

[0036] Figure 3It is an exemplary structural diagram of a wall hook shown in some embodiments of this specification.

[0037] The wall hook 130 is a structure that contacts the ceiling and is used to engage with the bottom plate 110 to clamp the ceiling. Figure 3 As shown, the wall hook 130 includes a connecting portion 131 and a fixing portion 132. The connecting portion 131 is provided with a threaded hole threadedly connected to the screw rod 120, and the fixing portion 132 is configured to contact the wall. The connecting portion 131 coincides with the axis of the screw rod 120, and the screw rod 120 can drive the fixing portion 132 to rotate around the axis of the screw rod 120 after the screw rod 120 rotates.

[0038] In some embodiments, Figure 3 As shown, the position where the fixing part 132 contacts the wall is also provided with a concave-convex feature 133, which can increase the friction of the contact, thereby increasing the installation stability of the mounting bracket. The shape of the wall hook 130 can be rectangular or L-shaped ( Figure 3 The wall hook 130 may be made of metal (eg, aluminum alloy), plastic, etc.

[0039] The stopper 140 is a component fixed to the tail of the screw 120 to prevent the screw 120 from falling off, thereby limiting the position of the screw 120. For more information about the stopper 140, see Figure 5 .

[0040] Figure 4 It is an exemplary structural diagram of a guide member shown in some embodiments of this specification.

[0041] The guide member 150 is a component that guides the wall hook 130 to rotate to a corresponding position when the wall hook 130 rotates due to the rotation of the screw rod 120. Figure 4 As shown, the guide member 150 includes a channel 151 , a through slot 152 , and a guide feature 153 .

[0042] In some embodiments, the screw 120 is located in the channel 151. When the screw 120 rotates, the wall hook 130 rotates or moves up and down in the through slot 152 along the guide feature 153. The guide feature 153 is arc-shaped, and the guide feature 153 and the through slot 152 together define the moving path of the wall hook 130. The guide feature 153 is arc-shaped to prevent the wall hook 130 from getting stuck during the disassembly process (i.e., the reverse process of the installation process); and to avoid the problem of the wall hook being easily stuck when approaching the guide feature 153 from the through slot 152 when using designs such as sharp corners.

[0043] In some embodiments, the guide member 150 further includes a through hole 154 and a baffle feature 155. The screw rod 120 can pass through the through hole 154 and be slidably connected to the guide member 150. The baffle feature 155 is higher than the guide feature 153. When the screw rod 120 drives the wall hook 130 to rotate a certain angle and touches the baffle feature 155, the wall hook 130 can be blocked, and the wall hook is prompted to move up and down along the through slot 152 relative to the screw rod.

[0044] Exemplarily, the installation process of the mounting bracket 100 is as follows:

[0045] like Figure 1 As shown, before the mounting bracket 100 is installed, the wall hook 130 is located in the first position (i.e. Figure 1 As shown). The first position is the position of the wall hook before the mounting bracket is installed. When the installer starts to install the product equipped with the mounting bracket, the screw 120 is rotated by a tool. Since the screw 120 is threadedly connected to the wall hook 130, the wall hook 130 does not contact the baffle feature 155 on the guide member 150 at this time. The rotation of the screw 120 drives the wall hook 130 to rotate (at this time, the screw 120 and the wall hook 130 are relatively stationary). After the wall hook 130 rotates 90 degrees, the wall hook 130 can no longer rotate because the fixed part 132 of the wall hook 130 is blocked by the baffle feature 155. At this time, the screw 120 continues to be rotated (at this time, the wall hook 130 and the screw 120 rotate relative to each other), and the wall hook 130 moves downward along the through slot 152 relative to the guide member 150 to the second position (i.e. Figure 2 The second position is the installed position of the mounting bracket.

[0046] In some embodiments, after the wall hook 130 moves to the second position, the distance between the concave-convex feature 133 of the wall hook 130 and the bottom plate 110 is the thickness of the ceiling (e.g., 20 mm). At this time, the lower surface of the ceiling contacts the bottom plate 110, and the upper surface contacts the concave-convex feature 133 of the wall hook 130. The wall hook 130 and the bottom clamp the ceiling, and the mounting bracket 100 is fixed to the ceiling.

[0047] In some embodiments of this specification, the wall hook is adjusted by rotating the screw rod, which can facilitate installation by the installer when the internal structure of the mounting bracket cannot be seen; at the same time, it can be adjusted to adapt to different ceiling thicknesses (that is, the distance between the wall hook and the base plate can be adjusted), so that the mounting bracket can cope with a variety of situations. It can be understood that the space required by the mounting bracket is only the space for the wall hook to rotate 90 degrees, so the mounting bracket can be used in situations where the space is small, such as corners at the edge of the ceiling, locations close to the structural wall, etc.

[0048] In some embodiments, Figure 1As shown, the limiting member 140 includes a buckle 142 and a fixing screw member 141. The buckle 142 is used to be fixedly connected to the bottom plate 110. The fixing screw member 141 is located at the end of the screw rod 120 and is used to limit the position of the screw rod 120 to prevent it from being separated from the buckle 142. The fixing screw member 141 is located above the buckle 142.

[0049] Figure 5 It is an exemplary structural diagram of the fastener shown in some embodiments of this specification.

[0050] In some embodiments, Figure 5 As shown, the snap member 142 includes a female buckle feature 1421 and a through hole feature 1422. The screw 120 passes through the through hole feature 1422 and is fixed to the fixing screw member 141. In some embodiments, a male buckle is provided on the bottom plate 110, and the female buckle feature 1421 is snap-connected with the male buckle. The male buckle can be a groove or a protrusion matching the female buckle feature 1421, and the groove or protrusion on the female buckle feature 1421 is snap-connected with the male buckle.

[0051] In some embodiments, Figure 5 As shown, each of the two flanges is provided with a female buckle feature 1421, and the bottom plate 110 is inserted from the middle of the two flanges and connected with both flanges by snapping; at this time, the bottom plate 110 is stuck in the middle of the two flanges, which improves the overall stability of the snap member 142. The through hole feature 1422 of the snap member 142 and the through hole 154 of the guide member 150 together constitute the limit of the upper and lower ends of the screw 120, ensuring that the screw 120 is always located in the position limited by the two during the rotation process, so that the screw 120 will not deflect when rotating. It can be understood that when concealed installation, the installer cannot observe the situation of the screw 120, so limiting the position of the screw can prevent the screw from being offset or misaligned due to the swing of rotation, thereby ensuring the installation effect. Similarly, when disassembling (disassembly is the reverse process of installation), the limit member 140 can prevent the screw 120 from coming out of the through hole feature 1422, thereby avoiding the situation where the screw 120 or the mounting bracket suddenly falls off.

[0052] In some embodiments of the present specification, the cooperation between the snap member and the guide member can prevent the screw from being offset or misaligned due to rotation, or from suddenly falling off during the disassembly process, thereby improving the stability of the installation.

[0053] In some embodiments, the material of the buckle 142 can be metal or plastic. In some embodiments, to ensure the timeliness and position limiting effect of the buckle, the material of the buckle 142 can be metal, such as carbon steel, hard aluminum alloy, etc.

[0054] In some embodiments, Figure 1As shown, the fixing screw member 141 includes a retaining ring and a groove located at the end (i.e., the tail) of the screw. The retaining ring is fixed in the groove, and the outer diameter of the retaining ring is greater than the inner diameter of the through-hole feature 1422. The retaining ring can be an annular part with openings at both ends. During assembly, the retaining ring is opened and placed in the groove. The retaining ring is tightened under the action of its own elastic force and is fixed in the groove. The retaining ring can also be a closed annular part, for example, an elastic ring, which is opened and placed in the groove and fixed to the groove by its own resilience.

[0055] In other embodiments, the fixing screw member includes a limit pin and a pin hole at the end (i.e., tail) of the screw, the limit pin passes through the pin hole, and the length of the limit pin is greater than the inner diameter of the through hole feature 1422. The pin hole is set at a position perpendicular to the axis of the screw.

[0056] In some embodiments, the limit pin may be a cylindrical pin, which is fixed in the pin hole by interference fit (i.e., the outer diameter of the limit pin is slightly larger than the inner diameter of the pin hole, and the pin is fixed by tight fit). In other embodiments, the limit pin may be a cotter pin, which passes through the pin hole, and the two legs of the cotter pin are bent and fixed to the screw 120.

[0058] Figure 7 This is another installation schematic diagram of the mounting bracket and the product shown in some embodiments of this specification. Figure 8 It is a top view schematic diagram of the mounting bracket and the product shown in some embodiments of this specification.

[0059] In some embodiments, Figure 6 and Figure 7 As shown, four mounting brackets 100 are provided, and the mounting brackets 100 fix the product 200 on the wall. Side A is the visible side of the product 200 after installation; Side B is the bottom contact surface between the product 200 and the ceiling of the wall after installation; Side C is the surface of the product 200 close to the ceiling opening after installation, and both Side B and Side C are invisible during installation.

[0060] In some embodiments, Figure 8 As shown, the bottom plate 110 can be implemented by the product housing 210 of the product 200. Figure 8 As shown, the circle at D represents a ceiling opening, and multiple cavities 111 are formed at D and the product shell 210 . The product shell 210 is the bottom plate 110 , and the mounting bracket 100 is disposed at the cavity 111 of the product shell 210 .

[0061] In some embodiments, before the mounting bracket 100 is installed, the wall hook is located in the cavity 111 (eg, Figure 7 and Figure 8 After the mounting bracket is installed, the wall hook is located outside the opening of the wall ceiling (after installation, the position of the wall hook can be seen in Figure 2 ), the product shell is fixed on the wall ceiling.

[0062] In some embodiments of the present specification, by utilizing the cavity formed by the product housing and the wall ceiling, the mounting bracket is set in the cavity, which can fully utilize the space without the need to additionally allocate an installation position for the mounting bracket, and is applicable to a wider range of installation spaces.
