Description

Technical Field

[0001] This utility model relates to the field of household electrical appliances, specifically to a wall-mounted appliance and its mounting bracket structure. 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] Existing wall-mounted electrical appliances such as switches and sockets have several shortcomings during installation. First, the dimensions of the wall grooves must be strictly controlled; they must be smaller than the area of ​​the subsequently installed cover plates or panels to achieve effective concealment, which poses a significant challenge to construction. Second, traditional installation methods result in cover plates or panels protruding noticeably from the wall, with a large protruding area and thickness typically exceeding 4mm. This design not only affects aesthetics but also disrupts the overall visual effect of the wall, failing to meet the increasingly popular minimalist style demands of modern decoration. Regarding fixing methods, while the commonly used push-button structure is easy to install, subsequent maintenance or replacement is difficult, requiring specialized tools and time-consuming. This fixing method limits the possibility of flexible replacement according to changes in decoration style and cannot adapt to the pursuit of personalized decoration in modern homes.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a wall appliance and its mounting bracket structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a mounting bracket structure, including: a first mounting bracket, a second mounting bracket, and a plurality of adjusting members. The second mounting bracket has mounting bracket fixing holes for connecting to a junction box, and the first mounting bracket covers the second mounting bracket. The second mounting bracket has a plurality of through holes, and the first mounting bracket has screw holes corresponding to the positions of the plurality of first mounting holes. The first end of the adjusting member is rotatably disposed in the through hole and is limited to prevent axial movement. The second end of the adjusting member is screwed into the screw hole. The end face of the second end of the adjusting member is provided with an auxiliary adjustment structure. By applying an external tool to the auxiliary adjustment structure, the adjusting member can be driven to rotate, thereby adjusting the distance between the first mounting bracket and the second mounting bracket.

[0008] The first end of the adjusting component is provided with an annular groove, and the adjusting component is set in the through hole through the annular groove to form an axial limit;

[0009] The first end of the adjusting component has an elastic buckle structure. The elastic buckle structure is inserted into the through hole so that the position of the annular groove enters the through hole.

[0010] Preferably, the first end of the adjusting member is provided with a slot extending from the end face towards the second end.

[0011] Preferably, both the first mounting bracket and the second mounting bracket are provided with module through holes, and the first mounting bracket and / or the second mounting bracket are provided with module mounting structures.

[0012] Preferably, the first mounting bracket is provided with multiple first module mounting holes, and the second mounting bracket is provided with second module mounting holes at the positions corresponding to the multiple first module mounting holes. The functional module can be installed into the first module mounting holes and the second module mounting holes by screws.

[0013] Preferably, the second module mounting hole is a threaded hole; and / or, the first module mounting hole is a through hole; and / or, the auxiliary adjustment structure is a slotted groove or a cross groove.

[0014] This utility model also provides a wall appliance, including the above-mentioned mounting bracket structure, a junction box, a functional module, and a panel. The second mounting bracket is fixed on the junction box, the functional module is fixed inside the junction box through the second mounting bracket and / or the first mounting bracket, and the panel is placed on the functional module.

[0015] Preferably, the functional module is fixed on the second mounting bracket, and the panel is placed on the functional module. The distance between the first mounting bracket and the second mounting bracket can be adjusted by rotating the adjustment component of the auxiliary adjustment structure, so that the first mounting bracket and the panel are on the same plane.

[0016] Preferably, the functional module is fixed on the first mounting frame by a module mounting structure, and the panel is placed on the functional module and the first mounting frame.

[0017] Preferably, the functional module is provided with multiple slots, and the panel is provided with multiple corresponding buckles, and the panel is fixed to the slots by the buckles.

[0018] The mounting bracket structure proposed in this utility model is divided into a first mounting bracket and a second mounting bracket. The position adjustment between the first mounting bracket and the second mounting bracket is achieved by rotating an adjusting member. One end of the adjusting member is rotatably connected to the second mounting bracket, and the first end of the adjusting member is limited and cannot move axially. When the adjusting member rotates, it will only drive the first mounting bracket to move axially, thereby achieving relatively precise adjustment, eliminating the height difference between the first mounting bracket and / or the panel and the wall, solving the problem of electrical appliances protruding from the wall due to traditional installation methods, and has the advantages of convenient installation, flexible adjustment, convenient maintenance and good aesthetics.

[0019] In one embodiment, when the panel and the first mounting bracket are on the same plane, the height difference between the first mounting bracket and the wall can be adjusted by adjusting the adjusting member, while the panel and the first mounting bracket can also be adjusted to be on the same plane.

[0020] In one embodiment, when the panel and the first mounting bracket are on different planes, that is, when the panel is also covered on the first mounting bracket, the height difference (depth of the first mounting bracket submerged in the groove) between the first mounting bracket and the wall can be adjusted by the first mounting bracket, thereby achieving the height difference between the panel and the wall.

[0021] In one embodiment, the first end of the adjusting member adopts an elastic snap-fit ​​structure, which is convenient for disassembly and assembly. When installing the first mounting bracket, the adjusting member can be installed on the first mounting bracket first, and then directly pressed into the second mounting bracket, which simplifies the assembly process and reduces the difficulty of operation.

Detailed Implementation

[0034] The following description, in conjunction with the accompanying drawings, further illustrates the specific implementation of the mounting bracket structure and wall appliance of this utility model. The mounting bracket structure and wall appliance of this utility model are not limited to the descriptions in the following embodiments.

[0035] Example 1

[0036] This embodiment proposes a mounting bracket structure that can be applied to electrical devices embedded in walls, such as wall switches and wall sockets. Figure 1-3 The image shows a wall socket, which includes the mounting bracket structure proposed in this embodiment. Specifically, in conjunction with... Figure 4 and Figure 5 As shown, the mounting bracket structure includes a first mounting bracket 1, a second mounting bracket 2, and multiple adjusting components 3. The first mounting bracket 1 covers the second mounting bracket 2. The second mounting bracket 2 is provided with multiple through holes 21, and the first mounting bracket 1 is provided with screw holes 11 corresponding to the through holes 21. The first end of the adjusting component 3 is rotatably disposed in the through hole 21 of the first mounting bracket 1, and the first end of the adjusting component 3 is limited and cannot move axially. The second end is screwed into the screw hole 11 of the second mounting bracket 2 by a thread 32. An auxiliary adjustment structure 33 is provided on the end face of the second end. By using an external tool to act on the auxiliary adjustment structure 33 to drive the adjusting component 3 to rotate, the distance between the first mounting bracket 1 and the second mounting bracket 2 can be adjusted.

[0037] In this embodiment, the first mounting bracket 1, the second mounting bracket 2, and multiple adjusting components 3 constitute an adjustable mounting bracket structure, which can be used to install wall sockets, wall switches, air conditioner controllers, etc. The mounting bracket structure is used to connect to a pre-installed junction box 4 on a wall or cabinet, and to a functional module 5, which can be a socket functional module, a switch functional module, an air conditioner controller module, etc. Both the first mounting bracket 1 and the second mounting bracket 2 have module through holes through which the functional module 5 passes. The second mounting bracket 2 has mounting bracket fixing holes 23 for connecting to the junction box 4. The first mounting bracket 1 and / or the second mounting bracket 2 have module mounting structures for fixing the functional module 5. Preferably, both the first mounting bracket 1 and the second mounting bracket 2 have module mounting structures for fixing the functional module 5, which can be adapted to different adjustment needs.

[0038] Combination Figure 1-3 as well as Figure 6As shown, when the mounting bracket structure of this embodiment is applied to a wall socket, the second mounting bracket 2 is fixed to the wall socket's junction box 4, and the first mounting bracket 1 is mounted on the second mounting bracket 2 away from the junction box 4. The functional module 5 is fixed to the second mounting bracket 2 through the module mounting structure. The main body of the functional module 5 passes through the module through-hole and is placed into the junction box 4. The panel 6 is placed on the functional module 5. In this embodiment, the panel 6 only covers the functional module 5 and does not cover the first mounting bracket 1. The distance between the first mounting bracket 1 and the second mounting bracket 2 can be adjusted by rotating the adjusting member 3 through the auxiliary adjusting structure 33, so that the first mounting bracket 1 and the panel 6 are on the same plane.

[0039] As another embodiment, with Figure 1-3 The embodiments are similar, but the shapes of the functional module 5 and the panel 6 are different. Therefore, the same second mounting bracket 2 can be used, while a different first mounting bracket 1 can be replaced to match the functional module 5 and the panel 6 with different shapes.

[0040] In another embodiment, the panel 6 is placed on the functional module 5 and the first mounting bracket 1, covering the functional module 5 and the first mounting bracket 1. The second mounting bracket 2 is fixedly connected to the junction box 4. The functional module 5 is fixed on the first mounting bracket 1 through the module mounting structure. The main body of the functional module 5 passes through the module through hole and is placed into the junction box 4. The distance between the first mounting bracket 1 and the second mounting bracket 2 can be adjusted by rotating the adjusting component 3 through the auxiliary adjusting structure 33, and the distance between the panel 6 and the wall or the junction box 4 can be adjusted.

[0041] The adjusting component 3 refers to a mechanical element with bidirectional connection function. Specifically, it can be implemented using a threaded rod structure at one end. The first end forms a rotatable connection with the second mounting bracket 2, and the first end of the adjusting component 3 is limited and cannot move axially (axial movement of the first end is restricted, only rotation is possible). The second end forms a threaded connection with the first mounting bracket 1. The through hole 21 refers to a circular channel penetrating the thickness of the second mounting bracket 2. Specifically, it can be implemented using an equally spaced array distribution to provide a rotational support surface for the adjusting component 3. The threaded hole 11 refers to a through hole with threads on its inner wall. Specifically, it can be implemented using a specification that matches the thread of the adjusting component 3, converting rotational motion into axial displacement. The auxiliary adjusting structure 33 refers to a tool engagement portion. A tool can directly drive the adjusting component 3 to rotate, thereby achieving axial adjustment of the first mounting bracket 1. Specifically, it can be implemented using a groove or protrusion to facilitate the application of torque by a standardized tool.

[0042] Specifically, when an external tool is inserted into and rotates the auxiliary adjustment structure 33, the adjusting member 3 rotates within the through hole 21. Since the first end of the adjusting member 3 is restricted from axial displacement by the through hole 21, the thread 32 at the second end engages with the threaded hole 11, generating a helical motion that forces the first mounting bracket 1 to move axially. The synchronous rotation of multiple adjusting members 3 adjusts the overall axial position of the first mounting bracket 1, eliminating the height difference between the first mounting bracket 1 and the wall. After the panel 6 is subsequently installed, the distance between the panel 6 and the wall can be adjusted, making it flush with or flush with the wall. This structure breaks through the traditional rigid connection method, achieving precise height adjustment of the first mounting bracket 1 through the controllable displacement characteristics of the threaded pair.

[0043] Compared to traditional snap-fit ​​structures that only achieve fixed-position locking and cannot compensate for height after installation, this embodiment achieves axial displacement adjustment of the first mounting bracket 1 while maintaining structural stability through the synergistic effect of a threaded connection at one end and a rotatable connection at the other end, albeit with axial restriction. Furthermore, the multi-point independent adjustment mechanism formed by multiple adjustment keys 3 can correct assembly errors caused by uneven wall surfaces, a function that single-point fixing structures cannot achieve.

[0044] In this embodiment, as Figure 5-7 As shown, the first end of the adjusting member 3 is provided with an annular groove 31, and the adjusting member 3 is axially limited within the through hole 21 through the annular groove 31. The annular groove 31 refers to a recessed structure surrounding the outer wall of the first end of the adjusting member 3, which can be achieved by machining or injection molding. The width of the annular groove 31 is adapted to the thickness of the inner wall of the through hole 21, so that the inner wall of the through hole 21 is embedded inside the annular groove 31 to form an axial limit. The axial limit restricts the displacement of the adjusting member 3 along its own axis, specifically achieved through the cooperation between the annular groove 31 and the inner wall of the through hole 21. The sidewall of the annular groove 31 contacts the inner wall of the through hole 21 to form a constraint, allowing the adjusting member 3 to rotate around its axis but preventing it from moving along the axis.

[0045] Specifically, during installation, the annular groove 31 and the inner wall of the through hole 21 form a snap-fit ​​structure, with the inner wall of the through hole 21 embedded in the recessed area of ​​the annular groove 31. When the adjusting component 3 is rotated by an external tool, the sidewall of the annular groove 31 remains in contact with the inner wall of the through hole 21, preventing axial displacement of the adjusting component 3 during rotation. This structure does not rely on elastic deformation or additional fixing components; it directly restricts the axial degree of freedom of the adjusting component 3 through the rigid fit between the annular groove 31 and the through hole 21, ensuring the connection stability between the first mounting bracket 1 and the second mounting bracket 2.

[0046] In this embodiment, we continue to refer to Figure 5-7The first end of the adjusting component 3 has an elastic undercut structure 34. This undercut structure 34 is inserted into the through hole 21, causing the annular groove 31 to enter the through hole 21. The elastic undercut structure 34 is a protruding structure with radial elastic deformation capability. Specifically, it can be implemented using a segmented claw-shaped structure with a notch at the end. When compressed, the segmented claw-shaped structure undergoes radial contraction deformation, and after passing through the through hole 21, it returns to its original shape, forming an axial barrier. The annular groove 31 is an annular recessed area located on the outer periphery of the first end of the adjusting component 3. It can be formed by turning or injection molding. The width of the annular groove 31 matches the thickness of the through hole 21, and when the groove enters the through hole 21, it forms a mechanical limit against the hole wall.

[0047] Specifically, when the elastic buckle structure 34 at the first end of the adjusting member 3 is inserted into the through hole 21 of the second mounting bracket 2 under axial pressure, the segmented claw structure is compressed by the hole wall, causing radial contraction, allowing the end to pass smoothly through the through hole 21. After the segmented claw structure has completely passed through the through hole 21, its elastic restoring force causes the claw structure to unfold again, at which point the annular groove 31 is exactly located inside the through hole 21. The inner wall of the through hole 21 and the side wall of the annular groove 31 form an axial constraint, preventing the adjusting member 3 from moving axially within the through hole 21. During this process, the deformation and reset of the elastic buckle structure 34 are completed automatically, without the need for manual adjustment of the alignment between the annular groove 31 and the through hole 21. In this embodiment, through the adaptive deformation characteristics of the elastic buckle structure 34, the positioning and engagement of the annular groove 31 and the through hole 21 are automatically completed during the insertion process. During assembly, it is not necessary to pre-install the adjusting member 3 onto the second mounting bracket 2, effectively reducing the technical difficulty of the assembly operation.

[0048] Through the above technical solution, this application achieves rapid assembly of the adjusting component 3, the first mounting bracket 1, and the second mounting bracket 2. During operation, only axial pressure needs to be applied to complete the automatic alignment and locking of the limiting structure, solving the problem of complex assembly procedures in traditional axial limiting structures. At the same time, the mechanical limiting structure formed by the annular groove 31 and the through hole 21 can effectively prevent the adjusting component 3 from axially moving under vibration, improving the stability of the mounting bracket structure.

[0049] Based on the above, compared with the prior art, in this embodiment, the thread at the second end of the adjusting member 3 extends directly to the annular groove 31. By rotating the adjusting member 3, the first mounting bracket 1 can be directly attached to the second mounting bracket 2, allowing for a larger adjustment range between the first mounting bracket 1 and the second mounting bracket 2, enabling height adjustment starting from 0mm. Furthermore, in this embodiment, the adjusting member 3 does not require screws to connect to the second mounting bracket 2. Instead, it is inserted into the through hole 21 of the second mounting bracket 2 via an elastic snap-fit ​​structure 34, with the annular groove 31 providing axial restraint, thus preventing screws from loosening and affecting adjustment accuracy when the adjusting member 3 is twisted. Moreover, the adjusting member 3 adopts an integrated structure, reducing the number of parts. During installation, it is not necessary to pre-install the adjusting member 3 onto the second mounting bracket 2; instead, it can be directly pressed into the second mounting bracket 2 after being installed onto the first mounting bracket 1, improving installation efficiency. Please refer to this embodiment for further details. Figure 5-7 The first end of the adjusting member 3 is provided with a slot 35 extending from the end face towards the second end. The slot 35 is a narrow slit extending axially along the adjusting member 3, which can be achieved through machining or injection molding. This slit penetrates the end of the adjusting member 3 and extends towards the second end. The gap formed by the slot 35 allows the end of the adjusting member 3 to contract under radial pressure, constituting the elastic factor of the elastic undercut structure 34, thereby reducing the resistance when the elastic undercut structure 34 is inserted into the through hole 21.

[0050] Specifically, when the adjusting member 3 is pressed into the through hole 21 of the second mounting bracket 2, the presence of the slot 35 enables the end of the adjusting member 3 to have elastic contraction capability. During the contact process between the elastic undercut structure 34 and the inner wall of the through hole 21, the gap of the slot 35 is compressed, and the diameter of the end of the adjusting member 3 decreases to smoothly pass through the through hole 21. After the elastic undercut structure 34 has completely passed through the through hole 21, the elastic recovery characteristic of the slot 35 causes the end of the adjusting member 3 to return to its original shape. At this time, the annular groove 31 and the edge of the through hole 21 form an axial limit. This process avoids the installation difficulties caused by the inability to deform rigid structures during assembly, while ensuring a reliable connection between the adjusting member 3 and the second mounting bracket 2. The slot 35 constitutes the elastic factor of the elastic undercut structure 34, so there is no need to pre-install the adjusting member 3 on the second mounting bracket 2. The adjusting member 3 only needs to be pressed in when the first mounting bracket 1 is officially installed. Of course, the elastic factor constituting the elastic undercut structure 34 is not limited to the slot 35, but can also be the elastic deformation of the material itself or other elastic structural forms.

[0051] In this embodiment, as Figure 3 and Figure 5As shown, the first mounting bracket 1 is provided with multiple first module mounting holes 12 as module mounting structures. The second mounting bracket 2 is provided with second module mounting holes 22 corresponding to the positions of the multiple first module mounting holes 12 as module mounting structures. The outer periphery of the functional module 5 is usually provided with third module mounting holes 52. The functional module 5 can be mounted to the first module mounting holes 12 and the second module mounting holes 22 by screws 53. The first module mounting holes 12 refer to through holes or threaded holes provided on the first mounting bracket 1. The second module mounting holes 22 can be through holes or threaded holes provided on the second mounting bracket 2.

[0052] In this embodiment, the auxiliary adjustment structure 33 is a slotted or Phillips head slot, or it can be a protruding hexagonal structure, etc. When the external tool is a conventional slotted or Phillips head screwdriver, the screwdriver tip is inserted into the corresponding slot, and the rotation of the tool drives the adjustment component 3 to rotate around its own axis. The thread 32 at the second end of the adjustment component 3 engages with the screw hole 11 of the first mounting bracket 1, generating axial displacement during rotation, thereby pushing the first mounting bracket 1 to make a fine adjustment of its position relative to the second mounting bracket 2. Since the slot structure is perfectly matched with the universal screwdriver tool, there is no need to change the tool or adjust the force angle during operation. The contact surface between the tool tip and the slot wall is evenly stressed, avoiding slippage or wear.

[0053] Example 2

[0054] like Figure 1-3 As shown, this embodiment proposes a wall appliance, including the mounting bracket structure described in Embodiment 1, a junction box 4, a functional module 5, and a panel 6. The second mounting bracket 2 is fixed on the junction box 4. The mounting bracket structure includes a first mounting bracket 1, a second mounting bracket 2, and multiple adjusting components 3. The functional module 5 is fixed inside the junction box 4 through the second mounting bracket 2 and the first mounting bracket 1. The panel 6 covers the functional module 5, and the panel 6 only covers the functional module 5.

[0055] The recessed box 4 refers to a box-shaped structure embedded in the wall, which can be made of metal or plastic through stamping. Its function is to provide rigid support for the mounting frame structure and conceal the functional module 5. The functional module 5 refers to a component with electrical functions. In this embodiment, the functional module 5 is a socket functional module, which is fixed to the mounting frame structure with screws. The panel 6 refers to the outer decorative part covering the functional module 5, which can be made of acrylic or tempered glass. Its function is to connect to the functional module 5 through a snap-fit ​​structure to simplify the appearance.

[0056] Specifically, the second mounting bracket 2 is fixedly connected to the junction box 4 by screws, allowing the entire structure to be embedded inside the wall. In this embodiment, the functional module 5 is fixed to the second mounting bracket 2, such as... Figure 3 and Figure 5As shown, the first mounting bracket 1 is provided with multiple first module mounting holes 12 as a module mounting structure, and the second mounting bracket 2 is provided with second module mounting holes 22 as a module mounting structure. They are fixedly connected by screws 53 that pass through the first mounting bracket 1 and connect to the second mounting bracket 2. The first mounting bracket 1 and the second mounting bracket 2 form an axially adjustable threaded connection via an adjusting member 3, which allows the surface of the first mounting bracket 1 to be flush with the wall or to maintain a low height difference. The panel 6 is detachably connected to the functional module 5 via a snap-fit ​​61, with only the operation buttons or socket areas exposed.

[0057] In this embodiment, the first module mounting hole 12 is a through hole, and the second module mounting hole 22 is a threaded hole. The first module mounting hole 12 and the second module mounting hole 22 form an axially aligned mounting channel. The screw 53 passes sequentially through the third module mounting hole 52 on the outer periphery of the functional module 5, the first module mounting hole 12, and then screws into the second module mounting hole 22. The diameter of the first module mounting hole 12 is larger than the screw shank diameter, allowing the screw to be finely adjusted in position within the hole. The threaded structure of the second module mounting hole 22 provides axial locking force. During installation, the functional module 5 is placed in the space between the first mounting bracket 1 and the second mounting bracket 2, submerged in the concealed box, and three-point fixation is achieved by tightening the screw. When the functional module 5 needs to be replaced, simply loosening the screw releases the constraint, preserving the original installation state of the first mounting bracket 1 and the second mounting bracket 2.

[0058] Since the first module mounting hole 12 is a through hole, its inner diameter can be designed to be slightly larger than the screw diameter, for example, the hole diameter can be 0.5-1 mm larger than the screw diameter. When there are machining deviations or assembly misalignments between the holes of the first mounting bracket 1 and the second mounting bracket 2, the screw can be adjusted laterally within the through hole range to avoid local deformation of the first mounting bracket 1 due to forced alignment. At the same time, the through hole structure ensures that the screw only forms a rigid connection with the threaded hole of the second mounting bracket 2, while the first mounting bracket 1 remains unconstrained in the through hole position, thus not affecting the adjustment function of the adjusting component 3 driving the axial movement of the first mounting bracket 1.

[0059] In some specific embodiments, the depth of the junction box 4 can be set to match the height of the second mounting bracket 2, for example, a junction box 4 with a depth of 30mm can be used with a second mounting bracket 2 with a height of 25mm. The mounting holes of the functional module 5 can be a combination of through holes and threaded holes, for example, a through hole with a diameter of 5mm can be provided on the first mounting bracket 1, and a corresponding M4 threaded hole can be provided on the second mounting bracket 2. The latch 61 of the panel 6 can be a flexible plastic part, for example, an L-shaped latch structure injection molded from PA66 material.

[0060] Traditional wall-mounted appliances using an external second mounting bracket cause the first mounting bracket to protrude at least 4mm from the wall. This solution, however, uses the junction box 4 and the adjusting component 3 to make the surface of the first mounting bracket 1 flush with the wall. Traditional clip-on fixing methods require prying the edge of the panel for disassembly, while this solution uses screws to secure the functional module 5 to the clip-on connecting panel 6; disassembly only requires removing the screws to separate the first mounting bracket 1. The clip-on connection design between panel 6 and functional module 5 allows users to replace decorative panels of different materials or colors without damaging the wall structure.

[0061] like Figure 8-9 As shown, this embodiment further proposes that the functional module 5 is provided with multiple slots 51, and the panel 6 is provided with multiple corresponding buckles 61. The panel 6 is fixed to the slots 51 by the buckles 61.

[0062] The bayonet 51 refers to a groove structure located on the edge or at a specific position of the functional module 5. Specifically, it can be formed into a U-shaped or L-shaped opening on the surface of the functional module 5 using injection molding to accommodate the locking part of the buckle 61. The buckle 61 refers to an elastic protrusion structure located on the back of the panel 6. Specifically, it can be injection molded from polycarbonate or nylon material, and its end has a barb. It achieves mechanical locking by deforming and inserting into the bayonet 51 and then returning to its original shape.

[0063] This embodiment enables tool-free quick assembly and disassembly of panel 6 and functional module 5, solving the problem of cumbersome disassembly in traditional snap-fit ​​structures. The one-way locking design of snap-fit ​​61 and latch 51 allows users to operate each connection point individually, ensuring installation stability while improving the efficiency of panel 6 replacement and adapting to the replacement needs of decorative panels of different thicknesses and materials.

[0064] Based on the above embodiments, the installation process of the wall socket is as follows:

[0065] S1, Insert the junction box into the groove that has been pre-cut in the wall;

[0066] S2. Use screws or clips to install the second mounting bracket onto the junction box (or you can install the second mounting bracket onto the junction box first and then insert it into the groove in the wall).

[0067] S3, Install the adjusting component onto the first mounting bracket using a screwdriver;

[0068] S4, Align the adjusting piece with the through hole of the second mounting bracket and press it in;

[0069] S5. Use a screwdriver to turn the adjusting piece to adjust the height of the first mounting bracket;

[0070] S6, install the functional modules and panel in sequence.

[0071] As can be seen from the above installation process, the installation process of the first mounting bracket in this embodiment does not require the pre-installation of the adjustment component on the second mounting bracket, and the end of the adjustment component is an elastic structure that can be directly pressed into the second mounting bracket. This makes the installation and adjustment of the first mounting bracket very simple. During the adjustment process, the rotation of the adjustment component will not cause its axial displacement, but will only drive the axial movement of the first mounting bracket, thereby achieving a precise adjustment process.

[0072] In the wall socket structure provided in the above embodiments, the panel and the first mounting bracket are basically on the same plane. Therefore, by adjusting the axial position of the first mounting bracket to be flush with the wall, the panel can also be kept flush with the wall. In some other embodiments, the panel may be directly placed on the first mounting bracket, that is, the panel and the first mounting bracket are not on the same plane. In this case, to keep the panel flush with the wall, the first mounting bracket needs to be adjusted to a certain distance below the wall to allow for the installation thickness of the panel.
