[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0041] The embodiment of the present application provides a ceiling conversion frame 100, which is generally installed at the installation hole of the indoor ceiling to facilitate the installation of ceiling appliances 200 such as lamps and bathroom heaters on the ceiling.

[0042] Figure 1 FIG. 1 is a schematic diagram of the installation of a ceiling conversion frame 100 and an electrical appliance 200 provided in an embodiment of the present application. Figure 1 As shown, the ceiling conversion frame 100 includes a frame body 1 and an anti-slip component 2. The frame body 1 is used to be fixedly connected to the ceiling. A quick-install portion 12 is provided on the frame body 1, and the quick-install portion 12 is used to connect with the electrical appliance 200, so as to realize the assembly of the electrical appliance 200 on the frame body 1. The anti-slip component 2 is connected to the frame body 1 and can rotate relative to the frame body 1. The anti-slip component 2 is used to prevent the electrical appliance 200 from escaping from the frame body 1.

[0043] When the ceiling conversion frame 100 provided in the embodiment of the present application is used, it is generally first connected to the corresponding structure on the electrical appliance 200 through the quick-install part 12, so as to achieve the initial fixation of the electrical appliance 200 on the frame 1, and the process is convenient and quick; then the anti-dropping part 2 can be rotated to prevent the electrical appliance 200 from falling out of the frame 1, thereby playing an anti-dropping function. Therefore, the ceiling conversion frame 100 provided in the embodiment of the present application is easy to install the electrical appliance 200, and can prevent the electrical appliance 200 installed therein from falling off, and is safer to use.

[0044] like Figure 2As shown, in the ceiling conversion frame 100 provided in the embodiment of the present application, the frame 1 has an installation opening 11. After the frame 1 is installed on the ceiling, the position of the installation opening 11 matches the position of the opening end of the installation hole on the ceiling. For example, the installation opening 11 of the frame 1 is located within the opening end of the installation hole, or the installation opening 11 of the frame 1 is connected to the opening end of the installation hole. At least a part of the electrical appliance 200 can be inserted into the installation opening 11 of the frame 1, so as to be accommodated on the inner side of the ceiling, achieving a visually hidden effect.

[0045] The anti-dropping member 2 is located outside the edge of the installation opening 11 and is arranged adjacent to the edge of the installation opening 11. Optionally, the anti-dropping member 2 is connected to the surface of the frame 1 facing the ground. When the anti-dropping member 2 rotates relative to the frame 1, the rotation path of the anti-dropping member 2 has the following Figure 2 The first position shown, and Figure 4 The second position is shown.

[0046] When the anti-dropout member 2 is located at the first position, its orthographic projection on the opening plane of the mounting opening 11 has an overlapping area with the mounting opening 11, and the portion of the anti-dropout member 2 corresponding to the overlapping area is used to abut against the portion of the electrical appliance 200 that penetrates the mounting opening 11, thereby preventing the electrical appliance 200 from escaping from the mounting opening 11. For example, Figure 2 As shown, a part of the orthographic projection of the anti-slip member 2 located at the first position on the opening plane is located inside the mounting opening 11, and another part of the orthographic projection of the anti-slip member 2 located at the first position on the opening plane is located outside the mounting opening 11. It should be understood that the mounting opening 11 has a central axis pointing to the ground, and the opening plane of the mounting opening 11 is perpendicular to the central axis of the mounting opening 11.

[0047] The anti-slip component 2 located in the first position can form a shield in the opening direction of the installation opening 11. Therefore, after the electrical appliance 200 is installed, the anti-slip component 2 can be rotated to the first position. In this way, even if the electrical appliance 200 installed in the frame 1 is disconnected from the quick-release part 12, the position of the anti-slip component 2 will interfere with the position of the electrical appliance 200, thereby supporting the electrical appliance 200, thereby preventing the electrical appliance 200 from falling out of the installation opening 11, thereby improving the installation and use safety of the electrical appliance 200.

[0048] In an embodiment, Figure 1 As shown, the electrical appliance 200 includes a panel 201 and a mask 202. The mask 202 is disposed and connected to a side of the panel 201 close to the ground, and a gap is partially formed between the panel 201 and the mask 202. After the electrical appliance 200 is installed in the frame 1, as shown in FIG. Figure 3As shown, the panel 201 is located at the inner side of the installation opening 11, and the mask 202 is located at the side of the installation opening 11 close to the ground. The portion of the anti-dropping member 2 located at the first position corresponding to the overlapping area can abut against the portion of the electrical appliance 200 that penetrates the installation opening 11 (i.e., the side of the panel 201 facing the ground), thereby preventing the panel 201 from slipping out of the installation opening 11, and further preventing the electrical appliance 200 from slipping out of the ceiling conversion frame 100 and falling off.

[0049] When the anti-dropping member 2 is located at the second position, its orthographic projection on the opening plane of the mounting opening 11 has no overlapping area with the mounting opening 11. Exemplarily, the orthographic projection of the anti-dropping member 2 located at the second position on the opening plane is located outside the mounting opening 11 and adjacent to the edge of the mounting opening 11; or Figure 4 As shown, the orthographic projection of the anti-dropping member 2 located at the second position on the opening plane is located outside the installation opening 11 , and there is a gap between the anti-dropping member 2 and the installation opening 11 .

[0050] The anti-dropping member 2 located at the second position will not block the opening direction of the installation opening 11, so when installing the electrical appliance 200, Figure 5 As shown, the anti-slip member 2 can be rotated to the second position, so that the anti-slip member 2 can avoid the installation opening 11 and will not hinder the installation of the electrical appliance 200 in the installation opening 11, thereby facilitating the installation of the electrical appliance 200 on the ceiling conversion frame 100.

[0051] Optionally, when rotating from the second position to the first position, the rotation angle of the anti-dropping member 2 is greater than zero and less than 360 degrees. Figure 4 The second position shown is Figure 2 In the first position shown, the rotation angle of the anti-dropping member 2 is 90 degrees.

[0052] In some embodiments of the present application, Figure 6 As shown, the anti-slip component 2 may include a connecting portion 21 and a stopping portion 22, wherein the connecting portion 21 is used to realize the connection of the anti-slip component 2 on the frame body 1, and the stopping portion 22 is used to rotate between a first position and a second position, thereby preventing the electrical appliance 200 installed in the ceiling conversion frame 100 from falling out.

[0053] Optionally, the connection portion 21 is fixedly connected to the frame body 1 , and the stopper portion 22 is rotatably connected to the connection portion 21 . In this case, only the stopper portion 22 can rotate relative to the frame body 1 .

[0054] Optionally, the connection portion 21 is rotatably connected to the frame 1 , and the stopper 22 is fixedly connected to the connection portion 21 . In this case, the connection portion 21 can drive the stopper 22 to rotate relative to the frame 1 .

[0055] Optionally, the connecting portion 21 is rotatably connected to the frame 1, and the stopper 22 is rotatably connected to the frame 1. In this case, both the connecting portion 21 and the stopper 22 can rotate relative to the frame 1, and the rotation of the connecting portion 21 and the rotation of the stopper 22 are independent of each other.

[0056] In some embodiments, Figure 6 As shown, the connecting part 21 is a shaft body, which can be, for example, a cylindrical rotating shaft, or a conical or truncated cone-shaped shaft pin. The shaft body and the frame body 1 are fixedly connected, for example, a corresponding assembly hole is provided on the surface of the frame body 1 facing the ground, and a part of the shaft body is inserted into the assembly hole to achieve connection by interference fit or threaded connection.

[0057] Continue to see Figure 6 The stopper 22 is a paddle, and an axial hole 224 is provided on the paddle. The shaft body is passed through the axial hole 224, and there is a clearance fit between the shaft body and the axial hole 224, so that the paddle can rotate relative to the shaft body. The paddle has a first side 221 and a second side 222 adjacent to each other. The distance between the axial hole 224 and the first side 221 is greater than the distance between the axial hole 224 and the edge of the mounting opening 11, and the distance between the axial hole 224 and the second side 222 is less than or equal to the distance between the axial hole 224 and the edge of the mounting opening 11.

[0058] As the paddle rotates, the first side edge 221 can be rotated to the inner side of the mounting opening 11 so that the paddle is located in the first position, thereby forming a shielding in the opening direction of the mounting opening 11; continue to rotate the paddle, the first side edge 221 is rotated to the outer side of the mounting opening 11, and the second side edge 222 is rotated to between the mounting opening 11 and the shaft body, thereby avoiding the paddle from continuously blocking the mounting opening 11, and facilitating the installation of the electrical appliance 200 on the frame 1.

[0059] In some embodiments of the present application, Figure 6 As shown, the shape of the orthographic projection of the paddle on the opening plane is a rectangle. The paddle also has a third side 223, the third side 223 and the first side 221 are opposite in the length direction of the paddle, the second side 222 is located in the width direction of the paddle, and the length of the paddle is greater than the width of the paddle. The shaft hole 224 is offset relative to the center of the paddle, specifically, the distance between the shaft hole 224 and the third side 223 is less than the distance between the shaft hole 224 and the first side 221.

[0060] In some embodiments of the present application, Figure 7 As shown, the anti-dropping member 2 further includes an operating portion 23, which is connected to the stopper 22 and is used to drive the stopper 22 to rotate relative to the frame 1 under external actuation. Exemplarily, the user can push the operating portion 23 to rotate, thereby driving the stopper 22 to rotate relative to the frame 1.

[0061] In some examples, the operating portion 23 may include a vertical plate, which is vertically arranged on the plate surface of the paddle, and the vertical plate and the paddle are rigidly connected, so that the paddle and the operating portion 23 as a whole form a T-shaped structure or an L-shaped structure to facilitate user operation.

[0062] In other examples, such as Figure 7 As shown, the stopper 22 has a first side wall 225 and a second side wall 226 that are opposite and spaced apart in the rotation direction of the anti-slip member 2. It is easy to understand that the rotation direction of the anti-slip member 2 is clockwise or counterclockwise. Further considering that the paddle rotates around the center line of the shaft body, the two side walls of the paddle opposite to each other in the width direction are used as the first side wall 225 and the second side wall 226. The operating portion 23 includes a first vertical plate 231 and a second vertical plate 232, which are respectively connected to the first side wall 225 and the second side wall 226, and a portion of the first vertical plate 231 is located on the side of the stopper 22 away from the frame body 1, and a portion of the second vertical plate 232 is located on the side of the stopper 22 away from the frame body 1, so as to facilitate user operation.

[0063] At the same time, since the operating part 23 is set in this way, the paddle and the surface of the frame 1 facing the ground maintain surface contact, so there is a relatively large friction between the two, which can prevent the anti-slip component 2 from spontaneously rotating from the first position to the second position under vibration or shaking, thereby causing the anti-slip function of the anti-slip component 2 to fail.

[0064] In some embodiments of the present application, Figure 2 As shown, the number of the anti-slipping members 2 is at least two, and the at least two anti-slipping members 2 are distributed on two opposite sides of the installation opening 11 .

[0065] By distributing at least two anti-slip parts 2 on both sides of the installation opening 11, a balanced supporting force can be provided for the electrical appliance 200. When the electrical appliance 200 is disconnected from the quick-release part 12 on the frame 1, the at least two anti-slip parts 2 located on both sides of the installation opening 11 enable the electrical appliance 200 to maintain a balanced force, thereby preventing the electrical appliance 200 from tilting or even falling due to unilateral force.

[0066] Optionally, at least two anti-dropout members 2 are arranged in pairs, and each pair of anti-dropout members 2 includes two anti-dropout members 2 distributed on opposite sides of the installation opening 11 .

[0067] Optionally, the number of the anti-dropping members 2 is at least two pairs, and the at least two pairs of anti-dropping members 2 are evenly spaced along the outer circumference of the ceiling conversion frame 100 , thereby playing a role in evenly supporting the electrical appliance 200 .

[0068] Optionally, the number of the anti-dropping members 2 is at least two pairs, and the at least two pairs of anti-dropping members 2 are arranged along the length direction of the ceiling conversion frame 100 .

[0069] Optionally, the quick-installation portion 12 may be disposed between two adjacent anti-detachment members 2 , thereby avoiding mutual interference between the quick-installation portion 12 and the anti-detachment members 2 .

[0070] In the embodiment of the present application, the quick-installation part 12 is used to realize the quick and convenient installation of the electrical appliance 200 on the frame 1. For example, the quick-installation part 12 can provide at least one of a snap-on installation position, a hook-on installation position, a hanging installation position, a plug-in installation position, and an elastic clamping installation position.

[0071] Optionally, when the quick-install part 12 and the electrical appliance 200 have a buckle and a slot respectively, the quick-install part 12 is used to provide a snap-fit ​​installation position for the electrical appliance 200 .

[0072] Optionally, when the quick-install portion 12 and the electrical appliance 200 have a hook portion and a groove portion (or a hole portion) respectively, the quick-install portion 12 is used to provide a hooking installation position for the electrical appliance 200 .

[0073] Optionally, when the quick-install part 12 and the electrical appliance 200 have a hook and a hanging ear respectively, the quick-install part 12 is used to provide a hanging installation position for the electrical appliance 200 .

[0074] Optionally, when the quick-install part 12 and the electrical appliance 200 respectively have a male plug-in end and a female plug-in end that can be interference-fitted, the quick-install part 12 is used to provide a plug-in installation position for the electrical appliance 200 .

[0075] Optionally, when the quick-install part 12 and the electrical appliance 200 respectively have an elastic clamping part and a clamped part, the quick-install part 12 is used to provide an elastic clamping installation position for the electrical appliance 200. For example, Figure 2 As shown, the quick-installing portion 12 includes at least two spring buckles, which are arranged in pairs, and each pair of spring buckles includes two spring buckles respectively located on the inner walls of the frame 1 on opposite sides for surrounding the installation opening 11. When the electrical appliance 200 is installed on the frame 1, the connecting piece on the electrical appliance 200 can extend into the spring buckle, so that the spring buckle can play an elastic clamping role on the connecting piece of the electrical appliance 200, thereby achieving preliminary fixation of the electrical appliance 200 and preventing the electrical appliance 200 from detaching from the frame 1. The direction of the elastic force applied by the spring buckle to the connecting piece is perpendicular to the opening direction of the installation opening 11.
