Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a wall-mounted electrical appliance. Background Technology

[0002] Wall-mounted electrical appliances typically include switches, sockets, and other appliances. These appliances are usually embedded in grooves in the wall, so that most of their volume is inside the wall, thus ensuring the practicality and aesthetics of the appliance installation.

[0003] The traditional installation method for existing wall appliances involves fixing the appliance to a junction box inside the wall during installation. This traditional method results in the cover plate or panel protruding significantly from the wall surface. The protruding part is large and usually more than 4mm thick. This design not only affects the aesthetics but also damages the overall visual effect of the wall, making it difficult to meet the increasingly popular minimalist style requirements in modern decoration.

[0004] Secondly, in existing technologies, the distance between the panel of wall-mounted appliances and the wall surface is not adjustable, resulting in poor operability.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0006] The purpose of this utility model is to overcome at least one defect of the prior art and provide a wall appliance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

The outer side wall of the functional component is provided with an external thread, and the inner side wall of the rotating ring is provided with an internal thread that engages with and drives the external thread. The cover plate is used for fixed installation with a junction box. The rotating ring is sleeved on the functional component so that the external thread and the internal thread engage. Rotating the rotating ring causes the functional component to move along the rotation axis of the rotating ring. The cover plate is provided with a first through hole, and the functional component can extend out from the first through hole when it moves along the rotation axis of the rotating ring.

[0009] In one possible implementation, the wall appliance further includes a panel that snaps onto the functional components, the panel being the same size as the first through hole.

During installation, the first buckle extends into the second arc-shaped hole of the buckle hole. By rotating the panel, the first buckle moves to the first arc-shaped hole, and the barb of the first buckle hooks onto the bottom of the first arc-shaped hole.

[0011] In one possible implementation, the wall appliance is a wall socket and / or a wall switch.

[0016] In one possible implementation, the first positioning part is a positioning post extending toward the mounting bracket, and the second positioning part is a positioning hole or positioning groove that is inserted into and positioned with the positioning post.

[0017] In one possible implementation, the wall appliance further includes a locking member near the side wall of the rotating ring, the side wall of the rotating ring having a first limiting portion and the locking member having a second limiting portion. When the rotating ring rotates in a first direction, the first limiting portion and the second limiting portion are unlocked, allowing the rotating ring to rotate in the first direction. When the rotating ring rotates in a second direction, the first limiting portion and the second limiting portion are locked, preventing the rotating ring from rotating in the second direction. The first direction and the second direction are opposite.

[0018] In one possible implementation, the first limiting part is a plurality of toothed grooves arranged in a ring along the side wall of the rotating ring, and the second limiting part is a protrusion provided on the locking member. The protrusion is stuck in the toothed groove. When the rotating ring rotates in the first direction, the protrusion is disengaged from the toothed groove and can move to the next toothed groove. When the rotating ring rotates in the second direction, the protrusion abuts against the toothed groove.

[0019] In one possible implementation, the functional component includes a circular operating part and a rectangular component part, the diameter of the operating part being greater than the maximum side length of the component part, the outer side wall of the operating part being provided with the external thread, the swivel being sleeved on the operating part, the operating part being provided with a first notch located between the swivel and the operating part, the locking member being disposed within the first notch, and the second limiting part being disposed on the inner side wall of the swivel.

[0023] In one possible implementation, the wall appliance further includes a drive unit, the drive unit comprising a first drive portion, and the rotating ring having a second drive portion, the drive unit being connected to the second drive portion via the first drive portion to drive the rotating ring to rotate.

[0024] In one possible implementation, the first driving part is a driving protrusion extending toward the rotating ring, and the second driving part is a driving groove or driving hole that mates with the driving protrusion.

[0026] Compared to existing technologies, this application provides a wall appliance, including a functional component, a cover plate, and a rotating ring. The rotating ring is fitted onto the functional component, and the functional component is at least partially located inside a recessed box. The cover plate is used for fixed installation with the recessed box. The rotating ring and the functional component are threadedly engaged and linked. By rotating the rotating ring, the functional component can be extended and retracted, thereby achieving relatively precise adjustment, eliminating the height difference between the functional component and the wall, and enabling the wall appliance to be fully embedded in the wall. This solves the problem of the appliance protruding from the wall due to traditional installation methods, and has the advantages of convenient installation, flexible adjustment, convenient maintenance, and good aesthetics.

[0027] In addition, the wall appliance also includes a panel that is snapped onto the functional components. The panel has the same structural size as the first through hole, and the rotating ring makes the panel flush with the wall.

[0028] Furthermore, a first buckle is provided on the side of the panel facing the functional component. The functional component has a buckle hole, which includes a first arc-shaped hole and a second arc-shaped hole that are connected. The width of the second arc-shaped hole is greater than the width of the first arc-shaped hole. During installation, the first buckle extends into the second arc-shaped hole of the buckle hole. By rotating the panel, the first buckle moves to the first arc-shaped hole, and the barb of the first buckle hooks onto the bottom of the first arc-shaped hole. The panel and the functional component are fixedly installed through the rotating structure of the buckle, which enables the panel to be disassembled and assembled, making it more convenient and quick to replace the panel or functional component module. In addition, the panel covering the first through hole has an installation protection function.

[0029] In addition, the wall appliance includes a mounting bracket installed between the junction box and the functional components, which makes the installation of the functional components and the junction box more secure and convenient, and the wall appliance has higher structural strength.

[0030] Furthermore, the wall appliance also includes a locking component near the side wall of the rotating ring. The side wall of the rotating ring has a first limiting part, and the locking component has a second limiting part. The first limiting part and the second limiting part are in contact. When the rotating ring rotates in the first direction X, the first limiting part and the second limiting part unlock, allowing the rotating ring to rotate in the first direction X. When the rotating ring rotates in the second direction Y, the first limiting part and the second limiting part lock, preventing the rotating ring from rotating in the second direction Y. The first direction X and the second direction Y are opposite, preventing the outwardly extending functional components from retracting. By setting the locking component, when the functional components are tightened and fixed to the mounting bracket, the rotating ring is prevented from reversing, preventing the functional components from retracting, improving the accuracy of the extension and retraction of the functional components, achieving relatively precise adjustment, and eliminating the height difference between the functional components and the wall.

[0066] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0067] like Figures 1-14As shown, this application provides a wall appliance, including a functional component 1, a cover plate 2, and a rotating ring 3. The outer side wall of the functional component 1 is provided with an external thread, and the inner side wall of the rotating ring 3 is provided with an internal thread that engages with the external thread. The functional component 1 is at least partially located inside a recessed box 4. The cover plate 2 is stacked on top of the recessed box 4 and is directly or indirectly fixedly installed to the recessed box 4. The rotating ring 3 is sleeved on the functional component 1 so that the external and internal threads engage. Rotating the rotating ring 3 allows the functional component 1 to extend and retract, and to reciprocate along the rotation axis of the rotating ring 3. Figure 8 As shown, the cover plate 2 is provided with a first through hole 21, and the functional component 1 can extend out from the first through hole 21 through axial movement.

[0068] Compared with the prior art, this application, by fitting a rotating ring 3 onto the functional component 1, with the rotating ring 3 and the functional component 1 engaged by threads, allows the functional component 1 to extend and retract when the rotating ring 3 is rotated, thereby achieving relatively precise adjustment, eliminating the height difference between the functional component 1 and the wall, and enabling the entire wall appliance to be embedded in the wall. This solves the problem of appliances protruding from the wall caused by traditional installation methods, and has the advantages of convenient installation, flexible adjustment, convenient maintenance, and good aesthetics.

[0069] In a preferred embodiment of this application, the rotating ring 3 is disposed inside the first through hole 21, or the rotating ring 3 is at least partially located inside the first through hole 21. In other feasible embodiments, the rotating ring 3 may also correspond to the first through hole 21 and be disposed below the cover plate 2.

[0070] Preferred, such as Figure 5 As shown, the wall appliance is a wall socket, and the functional component 1 includes a socket assembly 11 and a first pin hole 12 corresponding to the socket assembly 11. In other embodiments, the wall appliance can also be a wall switch, and the functional component 1 includes a touch switch and a button. In other embodiments, the wall appliance is both a wall socket and a wall switch, and the functional component 1 simultaneously includes a socket assembly 11, a touch switch, and a button. Further, the upper surface of the functional component 1 is provided with at least one set of first pin holes 12, and / or, at least one side wall of the functional component 1 is provided with at least one set of first pin holes 12 (not shown in this embodiment).

[0071] Preferred, such as Figure 5 and Figure 6As shown, the functional component 1 includes a functional housing 18, which includes a first mounting groove 13. A terminal block 15, a socket assembly 11, and a pressure plate 14 are sequentially arranged within the first mounting groove 13. The pressure plate 14 is fixedly installed and limited by the first mounting groove 13, covering the socket assembly 11 and the terminal block 15. The pressure plate 14 has a first pin hole 12. Furthermore, the functional component 1 also includes a protective door 16, which is installed between the pressure plate 14 and the socket assembly 11, blocking the first pin hole 12. When a pin is inserted into the first pin hole 12, the protective door 16 can be driven to avoid the first pin hole 12, allowing the pin to smoothly engage with the socket assembly 11. After the pin is pulled out of the first pin hole 12, a return spring (not shown in the figure) connected to the protective door 16 drives the protective door 16 to continue blocking the first pin hole 12, thereby improving the socket's dustproof effect and installation protection performance.

[0072] In other embodiments, the functional housing 18 does not have a first mounting groove 13. The functional housing 18 can be fixed to the plug assembly 11, terminal block 15, pressure plate 14, and protective door 16 in other ways, for example, by a support rib for fixed and limiting connection. Further details of the embodiments are omitted.

[0073] Preferred, such as Figure 1 As shown, the wall appliance also includes a panel 5 that is snapped onto the functional component 1. The panel 5 has the same structural size as the first through hole 21 and can be inserted into the first through hole 21. The panel 5 is provided with a second pin hole 51 corresponding to the first pin hole 12 of the pressure plate 14 and the plug assembly 11. The panel 5 covering the first through hole 21 provides installation protection.

[0074] Furthermore, such as Figure 1 and Figure 5 As shown, panel 5 and functional component 1 are fixedly installed by a rotating snap-fit ​​structure, which allows panel 5 to be disassembled and installed, making it more convenient and quick to replace panel 5 or functional component 1 module. The side of panel 5 facing functional component 1 is provided with a first snap-fit ​​52, and functional component 1 is provided with a snap-fit ​​hole 17. The snap-fit ​​hole 17 includes a first arc-shaped hole and a second arc-shaped hole that are connected. The width of the second arc-shaped hole is greater than the width of the first arc-shaped hole. During installation, the first snap-fit ​​52 extends into the second arc-shaped hole of the snap-fit ​​hole. By rotating panel 5, the first snap-fit ​​52 moves to the first arc-shaped hole, and the barb of the first snap-fit ​​52 hooks onto the bottom of the first arc-shaped hole, thereby fixing panel 5 and functional component 1 in place.

[0075] Therefore, in the embodiment of setting panel 5, functional component 1 may not include pressure plate 14, and can be inserted into sleeve component 11 through second pin hole 51. Of course, functional component 1 may also not include protective door 16, and the protective door 16 may be set on the back of panel 5, which can also achieve the same technical effect.

[0076] Preferably, a first limiting structure is provided between the functional component 1 and the dark box 4, and the first limiting structure is used to locate the maximum distance that the functional component 1 can move axially towards the bottom of the dark box 4.

[0077] Preferred, such as Figure 1 , Figure 6 and Figure 12 As shown, the wall appliance includes a mounting bracket 6 connected to the junction box 4, and the cover plate 2 is fixedly installed to the junction box 4 via the mounting bracket 6. The functional component 1, after being adjusted in position, can also be fixedly connected to the mounting bracket 6 to fix its position. The mounting bracket 6 includes a first opening 61 and a guardrail 62 surrounding the first opening 61. The guardrail 62 serves as a first limiting structure. The functional housing 18 of the functional component 1 includes an operating part 181 and a component part 182 located at the bottom of the operating part 181. The component part 182 extends into the junction box 4 from the first opening 61, and the operating part 181 abuts against the guardrail 62. The mounting bracket 6 can be integrally formed with the junction box 4 or separately fixedly connected. In a preferred embodiment of this application, the mounting bracket 6 is made of metal and is separately installed. The metal structure of the mounting bracket 6 makes the installation of the functional component 1 and the junction box 4 more secure, reliable, and convenient, and increases the structural strength of the wall appliance. In other embodiments, it may not be made of metal; it can be a plastic plate or a glass plate, etc.

[0078] In another embodiment, the mounting bracket 6 may not be provided. The opening of the dark box 4 is provided with a first opening 61 and a guardrail 62 surrounding the first opening 61. The component part 182 extends into the dark box 4 from the first opening 61, and the operating part 181 abuts against the guardrail 62.

[0079] Furthermore, such as Figure 1 , Figure 6 and Figure 12 As shown, the dark box 4, the mounting bracket 6, and the first opening 61 are all rectangular structures, and the operating part 181 of the functional component 1 is circular, with a diameter greater than the maximum side length of the first opening 61. Furthermore, the external thread is provided on the outer wall of the operating part 181, and the thickness of the operating part 181 is equal to the thickness of the rotating ring 3, and the thickness of the cover plate 2 is also equal to the thickness of the rotating ring 3. Of course, in other embodiments, the thickness of the operating part 181, the thickness of the rotating ring 3, and the thickness of the cover plate 2 may not be equal.

[0080] Furthermore, such as Figure 2As shown, the radius of the inner ring of the rotating ring 3 is equal to the radius of the operating part 181. The rotating ring 3 is sleeved on the operating part 181 of the functional component 1. The radius of the first through hole 21 of the cover plate 2 is equal to the radius of the outer ring of the rotating ring 3. The cover plate 2 is sleeved on the rotating ring 3 through the first through hole 21.

[0081] Preferred, such as Figure 3 As shown, the wall appliance also includes a locking member 7 near the side wall of the rotating ring (which can be near the inner or outer side wall of the rotating ring 3). The side wall of the rotating ring has a first limiting part 31, and the locking member 7 has a second limiting part 71. The first limiting part 31 and the second limiting part 71 are in contact. When the rotating ring 3 rotates in the first direction X, the first limiting part 31 and the second limiting part 71 are unlocked, allowing the rotating ring 3 to rotate in the first direction X. When the rotating ring 3 rotates in the second direction Y, the first limiting part 31 and the second limiting part 71 are locked, preventing the rotating ring 3 from rotating in the second direction Y. The first direction X and the second direction Y are opposite, one is clockwise and the other is counterclockwise. This prevents the outwardly extending functional component 1 from retracting during daily use due to various plugging, unplugging, or pressing operations. When the functional component 1 extends outward beyond a predetermined position, a screwdriver or other tool can be used to pry open the locking member 7, unlocking the first limiting part 31 and the second limiting part 71, allowing the rotating ring 3 to be reversed, thereby retracting the functional component 1.

[0082] By setting the locking element 7, when the functional component 1 is tightened and fixed to the mounting bracket 6, the rotating ring 3 is prevented from rotating backward, the functional component 1 is prevented from retracting, the accuracy of the extension and retraction of the functional component 1 is improved, relatively precise adjustment is achieved, and the height difference between the functional component and the wall is eliminated. Of course, as a preferred embodiment, the locking element 7 may not be provided.

[0083] Furthermore, such as Figure 3 As shown, the first limiting part 31 is a plurality of tooth grooves arranged in a ring along the side wall of the rotating ring, and the second limiting part 71 is a protrusion provided on the locking member 7. The protrusion is stuck in the tooth groove. When the rotating ring 3 rotates in the first direction X, the protrusion can disengage from the tooth groove and move to the next tooth groove. When the rotating ring 3 rotates in the second direction Y, the protrusion abuts against the tooth groove.

[0084] In other embodiments, the locking member 7 has a plurality of annularly arranged grooves on its outer side, and the transition sidewall has protrusions; or, the locking member 7 has a plurality of annularly arranged teeth on its outer side, and the rotating ring sidewall has a plurality of annularly arranged grooves, with the teeth and grooves meshing and interlocking. When the rotating ring 3 rotates along the first direction X, the rotating ring 3 drives the locking member 7 to rotate through the multiple grooves. When the rotating ring 3 rotates along the second direction Y, the teeth limit the grooves, preventing the rotating ring 3 from rotating along the second direction Y. Of course, the locking member 7 may also have grooves, and the rotating ring 3 may have teeth.

[0085] Preferred, such as Figures 3-5 As shown, the locking member 7 is disposed on the inner side of the rotating ring 3, and the second limiting part 71 is disposed on the inner sidewall of the rotating ring 3. The operating part 181 has a first notch 1811 located between the rotating ring 3 and the operating part 181. The locking member 7 is disposed within the first notch 1811, and the second limiting part 71 is disposed on the inner sidewall of the rotating ring 3. Alternatively, in another embodiment, the locking member 7 may be disposed on the outer side of the rotating ring 3, and the second limiting part 71 may be disposed on the outer sidewall of the rotating ring 3.

[0086] Furthermore, such as Figure 4 As shown, the locking member 7 includes a stop 72, a support base 73, and an elastic member (not shown) for driving the stop 72 to rotate. The stop 72 is provided with a second limiting part 71. The support base 73 is fixedly installed in the first notch 1811. The stop 72 is rotatably installed on the support base 73. One end of the elastic member abuts against the operating part 181, and the other end abuts against the stop 72 to drive the stop 72 to rotate. In this embodiment, the rotating ring 3 rotates along the first direction X, and the stop 72 rotates along the second direction Y. As another embodiment, the support base 73 may not be provided, and the stop 72 may be rotatably installed in the first notch 1811.

[0087] Furthermore, such as Figures 9-11 As shown, the support base 73 has a first support column 731 at its top, and the stop 72 has a second through hole 721, which is sleeved on the first support column 731. The elastic element is a torsion spring, located between the stop 72 and the support base 73. The stop 72 has a plate-like structure, and the second limiting part 71 is one corner of the stop 72. The side of the stop 72 facing the support base 73 has a first protrusion 722 and a second arc-shaped protrusion 723 spaced apart. The second arc-shaped protrusion 723 is located at the bottom of the second through hole 721, and the middle part of the elastic element is limited by the second arc-shaped protrusion 723. Inside, two drive arms of the elastic element extend from between the first protrusion 722 and the second arc-shaped protrusion 723; an annular boss 724 is provided on the side wall of the second through hole 721; two first fixing protrusions 732 are provided on both sides of the top of the first support column 731; an elastic opening is provided in the middle of the first support column 731 along the axial direction; the two first fixing protrusions 732 are located on both sides of the elastic opening; the first support column 731 is installed in the second through hole 721; the two first fixing protrusions 732 extend into the second through hole 721; and the bottom of the two first fixing protrusions 732 abuts against the top of the annular boss 724.

[0088] Furthermore, such as Figures 11-12As shown, a second support column 733 is provided at the bottom of the support base 73, and a third through hole 63 is provided in the dark box 4 or the mounting bracket 6. The second support column 733 is installed in the third through hole 63. Two second fixing protrusions 734 are provided on both sides of the top of the second support column 733. An elastic opening is provided in the middle of the second support column 733 along the axial direction. The two second fixing protrusions 734 are located on both sides of the elastic opening. The second support column 733 is installed in the third through hole 63. The two second fixing protrusions 734 extend from the bottom of the mounting bracket 6 and abut against the bottom of the mounting bracket 6.

[0089] Furthermore, such as Figure 5 and Figure 11 As shown, the support base 73 has a first fixing boss 735 at one end, and a first fixing groove 1812 is provided on the side wall of the first notch 1811. The first fixing boss 735 is inserted into the first fixing groove 1812 to fix the support base 73 to the functional component 1, preventing the elastic element from driving the support base 73 to rotate. In a preferred embodiment, the two side walls of the first fixing groove 1812 are inclined towards each other (that is, the distance between the two side walls gradually decreases from the bottom of the first fixing groove 1812 to the opening of the first fixing groove 1812), and the two side walls of the first fixing boss 735 are inclined towards each other (that is, the distance between the two side walls gradually decreases from the bottom of the first fixing boss 735 to the top of the first fixing boss 735). The support base 73 is installed from top to bottom in the first notch 1811 along the extension direction of the functional component 1, and the first fixing boss 735 is installed from top to bottom in the first fixing groove 1812. The first fixing groove 1812 can limit the movement of the first fixing boss 735 in the front, back, left, and right.

[0090] Furthermore, such as Figure 5 and Figure 7 As shown, the upper surface of functional component 1 extends radially outward as a first limiting boss 19, protruding from the external thread. The tooth groove of the rotating ring 3 narrows radially outward, forming a second limiting boss 32 between the tooth groove and the internal thread. The first limiting boss 19 and the second limiting boss 32 serve as the first limiting structure. The first limiting boss 19 abuts against the second limiting boss 32, and the tooth groove is opposite to the side of the first limiting boss 19. Before rotating the rotating ring 3, the first limiting boss 19 and the second limiting boss 32 are in contact, and the upper surface of functional component 1 is flush with the upper surface of the rotating ring 3. Functional component 1 cannot extend into the wall appliance. Rotating the rotating ring 3 causes functional component 1 to extend outward relative to the rotating ring 3, and the first limiting boss 19 and the second limiting boss 32 separate.

[0091] Preferred, such as Figure 1 , Figure 13 and Figure 14As shown, the wall appliance also includes a drive component 8, which includes a first drive part 81 and a second drive part 33 on the rotating ring 3. The drive component 8 is connected to the second drive part 33 through the first drive part 81 to drive the rotating ring 3 to rotate. Using the drive component 8 to operate the rotating ring 3 is more convenient and easier.

[0092] Furthermore, such as Figure 7 and Figure 14 As shown, the first driving part 81 is a driving protrusion extending towards the rotating ring 3, and the second driving part 33 is a driving groove or driving hole that mates with the driving protrusion. The driving member 8, acting as a driving handle, drives the rotating ring 3 to rotate after being inserted into the driving groove or driving hole via the driving protrusion. Preferably, the driving member 8 can have multiple driving protrusions spaced apart, and the rotating ring 3 can have multiple driving holes or driving grooves spaced apart. Of course, the first driving part 81 can be a driving hole or driving groove, and the second driving part 33 can be a driving protrusion. It is easier to insert or remove the driving protrusion from the driving groove or driving hole, making operation more convenient. When the driving member 8 rotates, the driving protrusion on the driving member 8 mates with the driving groove on the rotating ring 3, causing the rotating ring 3 to rotate synchronously. The rotation of the rotating ring 3 is transmitted to the functional component 1 through the meshing between the external and internal threads, causing the functional component 1 to rise or fall axially.

[0093] In another embodiment, the outer wall of the cover plate 2 is provided with a drive hole, and a first tooth is provided around the outer wall of the rotating ring 3 as a second drive part 33. A gear is provided in the drive hole as the drive member 8. The side of the gear is provided with a second tooth. One side of the gear meshes with the first tooth through the second tooth, and the other side extends out of the drive hole from the outer wall of the cover plate 2 for actuation. Rotating the gear can drive the rotating ring 3 to rotate.

[0094] Furthermore, such as Figure 14 As shown, in a preferred embodiment of this application, the driving component 8 includes a circular driving handle 82 and an annular handle 83. A rectangular connecting platform 84 is provided between the driving handle 82 and the handle 83. The first driving part 81 is provided on the side of the driving handle 82 away from the handle 83. The structure of the driving component 8 of this application is more labor-saving and easier to operate.

[0095] Preferred, such as Figure 12 As shown, the mounting bracket 6 is fixedly installed at the opening of the dark box 4. The dark box 4 is provided with a first screw hole, and the mounting bracket 6 is provided with a second screw hole 64. Screws are passed through the second screw hole 64 and the first screw hole in sequence to fix the mounting bracket 6 to the dark box 4.

[0096] Preferred, such as Figure 5 and Figure 12As shown, the functional component 1 is positioned with the mounting bracket 6. The functional component 1 has at least one first positioning part 111 at its bottom facing the dark box 4, and the mounting bracket 6 has at least one second positioning part 65. The first positioning part 111 and the second positioning part 65 are installed correspondingly for positioning the functional component 1 and the mounting bracket 6. When the functional component 1 moves along the rotation axis of the rotating ring 3, the first positioning part 111 and the second positioning part 65 cooperate to guide and limit the movement, so that the functional component 1 can only move in a straight line and cannot rotate.

[0097] Furthermore, such as Figure 5 and Figure 12 As shown, the first positioning part 111 is a positioning post extending towards the mounting bracket 6, and the second positioning part 65 is a positioning hole or positioning groove that is inserted into and positioned with the positioning post. Alternatively, the second positioning part 65 can be a positioning post, and the first positioning part 111 can be a positioning hole or positioning groove.

[0098] In an embodiment where the mounting bracket 6 is not provided, the second positioning part 65 can be provided on the dark box 4, and the functional component 1 is positioned and installed with the dark box 4.

[0099] Preferred, such as Figure 4 and Figure 12 As shown, the functional component 1 is installed on the mounting bracket 6. The operating part 181 of the functional component 1 is provided with a third screw hole 1813, and the mounting bracket 6 is provided with a fourth screw hole 66. The third screw hole 1813 and the fourth screw hole 66 correspond to each other. After the functional component 1 is adjusted to a suitable extension length, screws are used to pass through the third screw hole 1813 and the fourth screw hole 66 in sequence to fix the functional component 1 and the mounting bracket 6.

[0100] During construction, the junction box 4, mounting bracket 6, and cover plate 2 are pre-embedded in the wall through an opening. The mounting bracket 6 is fixed to the junction box 4 with screws, and the cover plate 2 is fixed to the mounting bracket 6 with screws, with the cover plate 2 lower than the wall surface. During installation, the functional component 1 with the rotating ring 3 is passed through the mounting bracket 6. The operating part 181 of the functional component 1 abuts against the mounting bracket 6. The positioning post of the functional component 1 is inserted into the positioning hole of the mounting bracket 6 for positioning and guidance. Under the limitation of the positioning post and the positioning hole, the functional component 1 can only move axially along the positioning hole. At the same time, the functional component 1 and the mounting bracket 6 are pre-connected with screws, but not tightened, so that the functional component 1 can move within a certain range axially along the positioning hole.

[0101] Then, the locking element 7 is installed between the rotating ring 3 and the operating part 181 of the functional component 1, so that the locking element 7 is fixedly installed with the mounting bracket 6. One corner of the stop 72 on the locking element 7 is engaged in the tooth groove of the rotating ring 3, and the other end of the stop 72 abuts against the operating part 181, so that the stop 72 cannot rotate in the second direction Y, and the rotating ring 3 cannot rotate in the second direction Y. When adjusting the functional component 1, the rotating ring 3 rotates in the first direction X, and the driving stop 72 rotates in the first direction X. The rotation of the rotating ring 3 drives the functional component 1 to extend outward through the meshing internal and external threads. After adjusting the functional component 1 to a suitable position flush with the wall, the functional component 1 is fixedly installed with the mounting bracket 6 using screws. Finally, the panel 5 is snapped onto the functional component 1. After installation, filler materials such as mortar or concrete can be used to fill the space between the cover plate 2 and the functional component 1. After the filler material is smoothed with the wall, only the circular panel 5 flush with the wall surface remains on the wall surface, which is more aesthetically pleasing and simpler.
