[0036] See also Figure 1 to Figure 2 The embodiment of the present application provides an electrical device 1, which may include a mounting bracket 10 and an electrical structure 30. The mounting bracket 10 is mounted in a cavity 50 of a support structure 5, and the electrical structure 30 is accommodated in the mounting bracket 10, so that the electrical structure 30 does not need to be directly mounted on the support structure 5, and the electrical structure 30 is easily disassembled and installed from the mounting bracket 10. The mounting bracket 10 can also store cables, thereby improving the aesthetics of the surface of the support structure 5.

[0037] As an example, the cables can be arranged in the support structure 5, or the cables can also be arranged on the back of the support structure 5. The installed cables can be gathered in the mounting bracket 10 to be stored in the mounting bracket 10, so as to avoid the cables being exposed and observed by the user, thereby improving the aesthetics of the support structure 5, and the cables can also be stored and organized for easy management.

[0038] The electrical structure 30 may refer to a socket, a lamp, a camera or other electrical structures.

[0039] The supporting structure 5 may refer to a wall, a gypsum board, a floor, a cabinet, a bedside table or some other supporting structural members.

[0040] The cavity 50 of the support structure 5 may refer to a mounting groove provided on the support structure 5, or the cavity 50 of the support structure 5 may refer to a mounting hole provided on the support structure 5. For ease of understanding, the embodiment of the present application is explained by taking the cavity 50 of the support structure 5 as the mounting hole provided on the support structure 5.

[0041] In some embodiments, the mounting bracket 10 includes a mounting box 11, a support member 13 and a driving member 15. The mounting box 11 can be installed in the cavity 50 of the supporting structure 5. The driving member 15 can drive the support member 13 to rest against the inner wall of the cavity 50, thereby fixing the mounting box 11 in the cavity 50 of the supporting structure 5.

[0042] The installation box 11 has an opening 111 and a peripheral wall 113. For example, the shape of the installation box 11 can be roughly prism-shaped, and an end surface of the installation box 11 is provided with an opening groove, or the installation box 11 can be provided with an installation through hole, and the opening 111 is connected to the installation through hole. The electrical structure 30 is accommodated in the installation box 11.

[0043] It should be noted that the installation box 11 may also adopt other shapes, such as cylindrical, conical, pyramidal or other shapes, which is not limited in the present application.

[0044] The support member 13 is movably mounted on the peripheral wall 113 of the mounting box 11, so that the position of the support member 13 can be easily adjusted, so that the support member 13 and the inner wall of the cavity 50 are in closer contact, which helps to more stably fix the mounting bracket 10 in the cavity 50 of the supporting structure 5.

[0045] The driving member 15 is installed on the installation box 11, and the driving member 15 is used to drive the support member 13 to move from the first position to the second position along the first direction X, so that the support member 13 abuts against the inner wall of the cavity 50; wherein the first direction X is set at an angle to the extension direction Y of the peripheral wall 113, so that the driving member 15 can adjust the position of the support member 13, so that the mounting bracket 10 can be quickly installed and disassembled, which reduces the difficulty of installation and facilitates subsequent disassembly and maintenance.

[0046] Specifically, when the driving member 15 drives the supporting member 13 to be in the second position, as shown in FIG. Figure 1 As shown, the driving member 15 provides a force for the support frame, so that the support member 13 abuts against the inner wall of the cavity 50, and the support member 13 and the inner wall of the cavity 50 generate an interaction force, so that the mounting bracket 10 can be stably fixed in the cavity 50, which helps to quickly install the mounting bracket 10 in the cavity 50 of the support structure 5. In addition, when the driving member 15 no longer provides a force for the support member 13, the interaction force between the support member 13 and the inner wall of the cavity 50 disappears, and the support member 13 is easy to move from the second position to the first position, as shown in FIG. Figure 3As shown, the support member 13 is easily separated from the inner wall of the cavity 50 , which helps to quickly remove the mounting bracket 10 from the supporting structure 5 .

[0047] See also Figure 3 and Figure 5 In some embodiments, the mounting bracket 10 may further include a guide member 17. The guide member 17 may be disposed between the peripheral wall 113 and the support member 13. The support member 13 may be movably mounted on the guide member 17. The guide member 17 may provide guidance for the movement of the support member 13 between the first position and the second position, thereby helping to prevent the support member 13 from deviating from the first direction X, so that the movement trajectory of the support member 13 may be more stable.

[0048] The guide member 17 may have various structural forms.

[0049] As an example, see Figures 5 and 6 , the guide member 17 can be used as a fixed structure. The guide member 17 can be protruded from the peripheral wall 113 of the installation box 11, and the guide member 17 can include a first guide bar 171 and a second guide bar 173 that are spaced apart. Correspondingly, in this example, the support member 13 can include a support body 131, a first sliding bar 133 and a second sliding bar 135, and the first sliding bar 133 and the second sliding bar 135 can be protruded from the support body 131 and face the peripheral wall 113. When the support member 13 moves from the first position to the second position along the first direction X, the first guide bar 171 is attached to the first sliding bar 133, and the second guide bar 173 can be attached to the second sliding bar 135, so that the first guide bar 171 and the second guide bar 173 and the first sliding bar 133 and the second sliding bar 135 guide the support member 13.

[0050] Furthermore, the guide member 17 can also limit the movement of the support member 13 along the first direction X. Specifically, the end of the first guide bar 171 away from the peripheral wall 113 can be provided with a first buckle, and the end of the second guide bar 173 away from the peripheral wall 113 can be provided with a second buckle; the end of the first sliding bar 133 facing the peripheral wall 113 can be provided with a third buckle, and the end of the second sliding bar 135 facing the peripheral wall 113 can be provided with a fourth buckle. When the support member 13 moves from the first position to the second position along the first direction X, the first buckle can be located in the moving path of the third buckle, and the second buckle can be located in the moving path of the fourth buckle. When the support member 13 moves to the second position, the third buckle abuts against the first buckle, and the fourth buckle abuts against the second buckle, so that the guide member 17 can limit the movement of the support member 13 along the first direction X, which helps to prevent the support member 13 from leaving the second position.

[0051] The guide member 17 can be connected to the peripheral wall 113 of the installation box 11 as a separate structure; the guide member 17 can also be a part of the installation box 11, for example, the guide member 17 can be integrally formed with the peripheral wall 113 of the installation box 11.

[0052] It can be understood that the distance between the support body 131 and the peripheral wall 113 when the support member 13 is in the first position can be smaller than the distance between the support body 131 and the peripheral wall 113 when the support member 13 is in the second position, so that the support member 13 can move between the first position and the second position, which helps to achieve rapid installation and rapid removal of the mounting bracket 10. Specifically, when the support member 13 is in the first position, the support member 13 can be close to or in contact with the peripheral wall 113, such as Figure 3 and Figure 5 When the support member 13 is in the second position, the support member 13 can be away from the peripheral wall 113, as shown in FIG. Figure 1 shown.

[0053] As another example, see Figure 3 to Figure 4 The guide member 17 may also adopt a movable structure, for example, the guide member 17 may slide on the peripheral wall 113, so that the guide member 17 slides and drives the support member 13 to move. For details, please refer to the detailed description of the following embodiment.

[0054] See also Figures 4 to 5 In some embodiments, the driving member 15 may include a spiral driver 151, which is rotatably mounted on the mounting box 11. The spiral driver 151 rotates to drive the support member 13 to move from the first position to the second position. The support member 13 is driven to move by the spiral driver 151, which has a simple structure, is easy to install, and is easy to operate.

[0055] The screw driver 151 may include a head and a screw connected to each other. For example, the screw driver 151 may be a screw, a bolt without a nut, a rivet or other threaded structures.

[0056] The screw driver 151 can be installed in the installation box 11 in a variety of ways.

[0057] As an example, see Figures 5 and 6, the peripheral wall 113 of the mounting box 11 may be provided with a through hole 1135. The mounting bracket 10 may further include a connector 18, which may be mounted on the peripheral wall 113, for example, the connector 18 may be clamped between the first guide bar 171 and the second guide bar 173. The connector 18 may be provided with a threaded through hole, which may be coaxial with and opposite to the through hole 1135 on the peripheral wall 113, and the screw driver 151 may be passed through the through hole 1135 of the peripheral wall 113 and plugged into the threaded through hole of the connector 18. When the screw driver 151 rotates in the threaded through hole, the screw driver 151 may be extended and retracted along the axial direction of the threaded through hole. When the screw driver 151 extends outward from the peripheral wall 113, the screw driver 151 abuts against the support member 13, thereby pushing the support member 13 from the first position to the second position along the first direction X. When the screw driver 151 rotates to move into the installation box 11 , the interaction force between the screw driver 151 and the support member 13 disappears, and the abutment force of the support member 13 against the inner wall of the cavity 50 disappears simultaneously, making it easy to remove the support member 13 from the support structure 5 .

[0058] As another example, a retaining piece may be provided around the outer peripheral surface of one end of the spiral driver 151 close to the support member 13, and the support member 13 is provided with a slot structure that is engaged with the retaining piece, and when the spiral driver 151 is connected to the support member 13, the retaining piece may be engaged in the slot structure. When the spiral driver 151 rotates to move into the installation box 11, since the retaining piece is engaged in the slot structure, the retaining piece may drive the support member 13 to move toward the peripheral wall 113, that is, the spiral driver 151 may drive the support member 13 to move from the second position to the first position, so that the support member 13 may be more easily disassembled from the support structure 5.

[0059] In this example, a groove may be provided on the side of the support member 13 facing the peripheral wall, and the spiral driver 151 may be inserted into the groove to push the support member 13 to move, which helps to make the movement direction of the spiral driver 151 more stable, so as to push the support member 13 to move more stably.

[0060] It can be understood that in this example, the first direction X can be substantially parallel to the axial direction of the screw driver 151. The guide member 17 can be fixed to the peripheral wall 113 as a fixed structure to provide guidance for the movement of the support member 13.

[0061] It can be understood that the mounting bracket 10 may not be provided with the connecting member 18, and the peripheral wall 113 of the mounting box 11 may be directly provided with a threaded through hole, that is, the through hole 1135 may be a threaded through hole. The screw driver 151 may be directly plugged into the threaded through hole of the peripheral wall 113. When the screw driver 151 rotates, it pushes the support member 13 to move, which will not be described in detail.

[0062] See also Figure 3 to Figure 4As another example, the mounting box 11 may include a flange 115 wrapped around the peripheral wall 113. When the mounting bracket 10 is installed in the cavity 50 of the support structure 5, the flange 115 may overlap the support structure 5. The spiral driver 151 is rotatably disposed on the flange 115 along the extension direction Y of the peripheral wall 113 and is threadedly connected to the guide member 17. The spiral driver 151 drives the guide member 17 to slide in the extension direction Y of the peripheral wall 113 to drive the support member 13 to move between the first position and the second position, so that the spiral driver 151 can have a variety of installation forms, and the corresponding mounting bracket 10 can have a variety of structural types to meet the different needs of users.

[0063] Specifically, the installation box 11 may have two opposite first end faces and a second end face, and the flange 115 may be connected to the first end face. When the mounting bracket 10 is installed in the cavity 50 of the support structure 5, the flange 115 may be exposed to the support structure 5. It can be understood that the second end face may be located in the cavity 50 of the support structure 5, or may be located outside the support structure 5, for example, the second end face may be located on the back of the support structure 5. The cable connected to the electrical structure 30 may pass through the second end face and be received in the installation box 11, for example, the second end face may be provided with a wire hole, and the cable may be received in the wire hole.

[0064] In this example, the guide member 17 can be used as a movable structure to be slidably mounted on the peripheral wall 113. The axial direction of the screw driver 151 can be arranged at an angle to the first direction X. For example, the axial direction of the screw driver 151 can be substantially perpendicular to the first direction X.

[0065] When the screw driver 151 rotates, since the guide member 17 is connected to the screw driver 151 thread, the guide member 17 can move along the axial direction of the screw driver 151. The guide member 17 can move between the support member 13 and the peripheral wall 113, thereby driving the support member 13 to move from the first position to the second position along the first direction X, so that the support member 13 can abut against the inner wall of the cavity 50 of the support structure 5, thereby realizing the rapid installation of the mounting bracket 10. When the guide member 17 moves to be separated from the support member 13, the force between the guide member 17 and the support member 13 disappears, and the abutment force of the support member 13 against the inner wall of the cavity 50 disappears simultaneously, making it easy to remove the support member 13 from the support structure 5.

[0066] Please continue reading Figure 3 to Figure 4 In some embodiments, a guide surface may be provided on the side of the guide member 17 facing away from the peripheral wall 113 and / or on the side of the support member 13 facing the guide member 17. The guide surface is inclined relative to the extension direction Y of the peripheral wall 113. The guide member 17 may provide guidance for the movement of the support member 13 between the first position and the second position through the guide surface, thereby helping the support member 13 to have a more stable movement trajectory.

[0067] As an example, the side of the guide member 17 facing away from the peripheral wall 113 may have a first guide surface 1751, and the side of the support member 13 facing the guide member 17 may have a second guide surface 1372, and the first guide surface 1751 may abut against the second guide surface 1372. The first guide surface 1751 and the second guide surface 1372 are both inclined relative to the extension direction Y of the peripheral wall 113, and the first guide surface 1751 and the second guide surface 1372 are parallel, so that when the guide member 17 moves, the first guide surface 1751 of the guide member 17 pushes against the second guide surface 1372 of the support member 13, or the second guide surface 1372 of the support member 13 pushes against the first guide surface 1751 of the guide member 17, so that the guide surfaces (the first guide surface 1751 and the second guide surface 1372) can provide guidance for the movement of the support member 13 between the first position and the second position.

[0068] As another example, a first guide surface 1751 may be provided on the side of the guide member 17 facing away from the peripheral wall 113. The first guide surface 1751 may be inclined relative to the extension direction Y of the peripheral wall 113. The support member 13 may abut against the first guide surface 1751. The support member 13 may slide on the first guide surface 1751, so that the guide surface (first guide surface 1751) can provide guidance for the movement of the support member 13 between the first position and the second position.

[0069] As another example, the support member 13 may have a second guide surface 1372 on the side facing the guide member 17. The second guide surface 1372 may be inclined relative to the extension direction Y of the peripheral wall 113. The second guide surface 1372 may abut against the guide member 17. The guide member 17 may slide on the second guide surface 1372, so that the guide surface (second guide surface 1372) can provide guidance for the movement of the support member 13 between the first position and the second position.

[0070] The first guide surface 1751 and the second guide surface 1372 may be arranged in a variety of ways.

[0071] As an example, along the extension direction Y of the peripheral wall 113 , the first guide surface 1751 and the second guide surface 1372 may gradually move away from the peripheral wall 113 .

[0072] As another example, along the extension direction Y of the peripheral wall 113 , the first guide surface 1751 and the second guide surface 1372 may gradually approach the peripheral wall 113 .

[0073] When the guide member 17 is slidably mounted on the peripheral wall 113 as a movable structure, in some embodiments, the guide member 17 may include a guide body 175, the guide body 175 may be slidably abutted between the support member 13 and the peripheral wall 113, one of the guide body 175 and the support member 13 may be provided with a slide groove, and the other of the guide body 175 and the support member 13 may be provided with a sliding member, the extension direction of the slide groove is the same as the inclination direction of the guide surface, and the sliding member is suitable for sliding in the slide groove, thereby helping the movement trajectory of the support member 13 to be more accurate and helping the support member 13 to move more stably in the first direction X. In addition, when the spiral driver 151 drives the guide member 17 to slide back and forth, it can not only push the support member 13 to the second position, but also bring the support member 13 back to the first position, which helps the support member 13 to be removed from the inner wall of the support structure 5 more quickly, further improving the removal speed of the mounting bracket 10.

[0074] As an example, the guide member 17 may include a guide body 175 and a first sliding member 177 connected to each other, and the guide body 175 may be slidably abutted between the support member 13 and the peripheral wall 113. The first guide surface 1751 may be located on the guide body 175; the support member 13 may be provided with a first slide groove 1371, and the extension direction of the first slide groove 1371 may be the same as the inclination direction of the first guide surface 1751; the first sliding member 177 is suitable for sliding in the first slide groove 1371, so that the first slide groove 1371 cooperates with the first sliding member 177, which can make the moving track of the support member 13 more accurate and help the support member 13 move more stably in the first direction X. In addition, the cooperation between the sliding member and the slide groove (i.e., the cooperation between the first slide groove 1371 and the first sliding member 177) can drive the support member 13 to move between the first position and the second position.

[0075] Specifically, the outer surface of the peripheral wall 113 may be convexly provided with two ribs arranged opposite to each other, and the two ribs may be connected between the flange 115 and the peripheral wall 113. A sliding groove is formed between the two ribs, and the guide member 17 is slidably located in the sliding groove. The spiral driver 151 is penetrated through the flange 115, inserted in the sliding groove, and plugged into the threaded through hole on the guide member 17. When the spiral driver 151 rotates, the guide member 17 can move along the axial direction of the spiral driver 151. It can be understood that at this time, the guide body 175 of the guide member 17 slides in the sliding groove. The support member 13 can abut against the flange 115 and the guide body 175.

[0076] In this example, the support member 13 may include a support body 131 and a connection block 137 connected to each other, the connection block 137 may be against the guide member 17, and the support body 131 may be located on the side of the connection block 137 away from the guide member 17. The support body 131 may be against the inner wall of the cavity 50 of the support structure 5. The first guide surface 1751 and the first slide groove 1371 may be provided on the connection block 137 of the support member 13. The end surface of the connection block 137 may also be against the flange 115. When the guide member 17 slides, the first sliding member 177 slides in the first slide groove 1371. Since the first slide groove 1371 is inclined relative to the peripheral wall 113, when the guide member 17 slides, the first sliding member 177 pushes the inner wall of the first slide groove 1371, thereby driving the support member 13 to move between the first position and the second position.

[0077] There may be two first slide grooves 1371, and the two first slide grooves 1371 may be relatively arranged on opposite sides of the connecting block 137. Correspondingly, the guide member 17 may also include two first sliding members 177. The shape of the first sliding member 177 may be substantially cylindrical, or the first sliding member 177 may also adopt other shapes.

[0078] As another example, the positions of the first slide groove 1371 and the first sliding member 177 can also be interchanged. Specifically, the guide member 17 can be provided with a second slide groove, and the extension direction of the second slide groove is the same as the inclination direction of the first guide surface 1751; the support member 13 includes a second sliding member, and the second sliding member is suitable for sliding in the second slide groove, so that the cooperation between the sliding member and the slide groove (i.e., the cooperation between the second slide groove and the second sliding member) can drive the support member 13 to move between the first position and the second position. Among them, the specific structure and sliding mode of the second sliding member and the second slide groove can refer to the first sliding member 177 and the first slide groove 1371, and will not be repeated here.

[0079] See also Figure 3 and Figure 5 In some embodiments, the mounting bracket 10 may further include a decorative cover 19, which may be disposed on the mounting box 11 to limit the axial movement of the spiral driver 151, so that when the mounting bracket 10 is installed in the cavity 50 of the support structure 5, the spiral driver 151 may provide a stable force for the support member 13, which helps the support member 13 to stably rest against the inner wall of the cavity 50, thereby helping the mounting bracket 10 to be stably fixed in the cavity 50 of the support structure 5, and also helping to improve the overall aesthetics of the mounting bracket 10.

[0080] As an example, see Figure 3 to Figure 4The shape of the decorative cover 19 can be adapted to the shape of the flange 115, for example, the decorative cover 19 can be roughly annular. The flange 115 can be provided with a step hole 1151, and the head of the screw driver 151 can be located in the step hole 1151 and abut against the step surface in the step hole 1151. The screw of the screw driver 151 passes through the step hole 1151 to connect the guide member 17 or directly abut against the support member 13. The decorative cover 19 can be covered and clamped on the surface of the flange 115 to press the head of the screw driver 151 on the step surface, which helps to prevent the screw driver 151 from moving axially along the step hole 1151, and can also cover the screw driver 151, thereby improving the overall aesthetics of the mounting bracket 10.

[0081] As another example, see Figures 5 and 6 , since the spiral driver 151 can also be inserted into the peripheral wall 113. In this example, the decorative cover 19 can include an annular column and an annular cover arranged around the outer circumference of the annular column and located on the end surface of the annular column. The shape of the annular column can be adapted to the shape of the peripheral wall 113, so that the annular column can fit the inner surface of the peripheral wall 113, that is, the annular column can fit the inner surface of the peripheral wall 113. Thereby, the annular column can block the spiral driver 151 inserted into the peripheral wall 113 and limit the axial movement of the spiral driver 151 along the spiral driver 151. The annular cover can be snapped onto the flange 115 to fix the decorative cover 19 to the mounting box 11. In this way, the decorative cover 19 can adapt to different installation methods of the spiral driver 151 to expand the application range of the decorative cover 19 without the need to design and manufacture a variety of decorative covers 19.

[0082] See also Figure 3 to Figure 4 In some embodiments, a plurality of protrusions are provided on the side of the support member 13 facing away from the peripheral wall 113 , thereby increasing the friction between the support member 13 and the support structure 5 , and helping to more stably fix the mounting bracket 10 in the cavity 50 of the support structure 5 .

[0083] The number of the protrusions may be one or more.

[0084] There are many options for the shape of the protrusion. For example, the shape of the protrusion can be roughly a semicircular protrusion, a polygonal protrusion, an elliptical protrusion, or a protrusion of other shapes.

[0085] In some embodiments, the protrusion may be a strip-shaped protrusion 1311, and the extension direction Y of the strip-shaped protrusion 1311 and the peripheral wall 113 may be set at an angle, thereby increasing the friction between the strip-shaped protrusion 1311 and the supporting structure 5, and helping to more stably fix the installation bracket 10 in the cavity 50 of the supporting structure 5.

[0086] The cross-sectional shape of the strip protrusion 1311 may be semicircular, polygonal, elliptical or other shapes.

[0087] The number of the strip-shaped protrusions 1311 may be one or more.

[0088] As an example, the length direction of the strip-shaped protrusion 1311 may be perpendicular to the extension direction Y of the peripheral wall 113 , so as to further increase the friction between the strip-shaped protrusion 1311 and the supporting structure 5 .

[0089] See also Figure 3 and Figure 6 In some embodiments, the support member 13 may be close to the end surface of the installation box 11, or the support member 13 may be located on one side of the peripheral wall close to the opening 111. In this way, the mounting bracket 10 can adapt to support structures 5 of different thicknesses, thereby expanding the scope of use of the mounting bracket 10.

[0090] As an example, the support member 13 may be close to or in contact with the flange 115 .

[0091] See also Figure 1 In some embodiments, the mounting bracket 10 includes at least two support members 13 , and the at least two support members 13 are distributed at intervals along the circumference of the peripheral wall 113 , which helps to more stably fix the mounting bracket 10 in the cavity 50 .

[0092] Among them, the structure and movement mode of each support member 13 can be roughly the same, and each support member 13 can be driven by a driving member 15. For details, please refer to the driving member 15 and the support member 13 in the above embodiment, and no further details will be given.

[0093] The at least two support members 13 may be two support members 13 , three support members 13 , four support members 13 , or any other number of support members 13 .

[0094] When the mounting bracket 10 includes different numbers of support members 13 , the support members 13 may be distributed in different ways to more stably support the mounting bracket 10 in the cavity 50 .

[0095] As an example, when the mounting bracket 10 includes two support members 13 , the two support members 13 may be distributed along the circumference of the peripheral wall 113 and symmetrically arranged, which helps to more stably support the mounting bracket 10 in the cavity 50 .

[0096] As another example, when the mounting bracket 10 includes three support members 13 , the three support members 13 may be evenly distributed along the circumference of the peripheral wall 113 , which helps to more stably support the mounting bracket 10 in the cavity 50 .

[0097] As another example, when the mounting bracket 10 includes four support members 13, the four support members 13 can be distributed along the circumference of the peripheral wall 113, and two of the support members 13 can be symmetrically distributed, and the other two support members 13 can also be symmetrically distributed, which helps to more stably support the mounting bracket 10 in the cavity 50.

[0098] It can be understood that the distribution mode of the support members 13 in the above example is only used as an example to facilitate understanding, and the specific distribution mode of the support members 13 can be set according to actual needs.

[0099] In the mounting bracket 10 and the electrical device 1 provided in the embodiment of the present application, the mounting box 11 can be installed in the cavity 50 of the supporting structure 5, the support member 13 can be movably installed on the peripheral wall 113 of the mounting box 11, and the driving member 15 is installed on the mounting box 11. The driving member 15 is used to drive the support member 13 to move from the first position to the second position along the first direction X, so that the support member 13 abuts against the inner wall of the cavity 50, wherein the first direction X is set at an angle to the extension direction Y of the peripheral wall 113, so that the driving member 15 can adjust the position of the support member 13. When the driving member 15 drives the support member 13 to be in the second position, the support member 13 abuts against the inner wall of the cavity 50, and the driving member 15 provides a force for the support frame, so that the support member 13 and the inner wall of the cavity 50 generate an interaction force, so that the mounting bracket 10 can be stably fixed in the cavity 50, which is conducive to the rapid installation of the mounting bracket 10.

[0100] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
