However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] In interior decoration, the installation quality of wall-mounted electrical appliances such as switches, sockets, and smart panels directly affects the final aesthetics. Ideally, the edges of the electrical appliances should be flush with the finished wall surface, creating a seamless visual effect.

[0026] However, in actual construction, different finishing materials have different thicknesses, while the installation depth of the junction boxes used to install electrical appliances is usually fixed. This results in the end face of the electrical module often not being able to be precisely aligned with the surface of the finishing material after the wall appliance is installed. It either sinks into the wall to form a pit, which is easy to accumulate dust, or protrudes from the wall, which destroys the overall aesthetics and poses a risk of bumping and knocking.

[0027] In the prior art, to solve this problem, solutions such as adding washers or adjusting brackets between the junction box and the electrical components are usually adopted. However, these methods have limited adjustment range and are not very precise.

[0028] This embodiment provides an electrical appliance installation device, mainly used to install electrical appliances such as switches, sockets, night lights, and smart panels on various decorative materials (stone, ceramic tiles, wood panels, etc.). After installation, it is flush with the outer surface of the various decorative materials, achieving a seamless visual aesthetic. The following is a detailed description using the example of installing the electrical appliance installation device on a wood panel.

[0029] Referring to Figures 1 to 7, the electrical installation device includes a fixed base 100, a movable base 200, and an adjusting ring 300.

[0030] The fixed base 100 has a first channel inside and a first transmission mating part on its outer wall. A movable base 200 is slidably fitted into the first channel within the fixed base 100. The movable base 200 has a second channel inside for installing electrical appliances. The movable base 200 can move axially along the first channel. An anti-rotation guide mechanism is provided between the movable base 200 and the fixed base 100. The anti-rotation guide mechanism limits the circumferential rotation of the movable base 200 relative to the fixed base 100 and guides the movable base 200. Moving axially along the first channel, the anti-rotation guide mechanism is provided with a second transmission engagement part, and the rotation direction of the second thread 211 is the same as that of the first thread 110; the adjusting ring 300 has a third transmission engagement part on its inner wall, and the adjusting ring 300 is sleeved on the outside of the fixed seat 100. The third transmission engagement part of the adjusting ring 300 engages with the first transmission engagement part and the second transmission engagement part at the same time; the adjusting ring 300 is configured such that when it rotates, the adjusting ring 300 will push the movable seat 200 to produce axial displacement relative to the fixed seat 100.

[0031] The first transmission mating part is the first thread 110, the second transmission mating part is the second thread 211, and the third transmission mating part is the internal thread 310.

[0032] During installation, one end of the fixed base 100 is connected to the wooden board, and the electrical appliance is installed into the second channel of the movable base 200. Then, the adjusting ring 300 is rotated to move the movable base 200 along the axial direction of the fixed base 100 until the end face of the electrical appliance is flush with the surface of the wooden board. Therefore, during the installation process, the installer can adjust the extension length of the movable base 200 according to the thickness of the wooden board, thereby ensuring that the electrical appliance is perfectly flush with the surface after installation. This avoids dust accumulation in the recesses and eliminates the risk of bumps and knocks, greatly improving the installation quality and aesthetics.

[0033] In some embodiments, the anti-rotation guide mechanism includes sliders 210 and guide grooves 120. At least two guide grooves 120 are provided, and the two guide grooves 120 are formed on opposite side walls of the fixed base 100. The guide grooves 120 penetrate the side walls of the fixed base 100 and extend along the axial direction of the fixed base 100. The number of sliders 210 is the same as the number of guide grooves 120. Each slider 210 is installed on opposite side walls of the movable base 200. The distribution direction of each slider 210 on the movable base 200 is the same as the distribution direction of each guide groove 120 on the fixed base 100. Each slider 210 is respectively fitted in the corresponding guide groove 120. The exposed side of the slider 210 in the guide groove is provided with a second thread 211.

[0034] In the embodiments shown in this application, the fixed base 100 has a circular cross-section, that is, the fixed base 100 is a cylindrical structure, and the movable base 200 is also a cylindrical structure, with its outer diameter being slightly smaller than the inner diameter of the fixed base 100, so that the movable base 200 can be smoothly inserted into the fixed base 100 and slide along the axial direction.

[0035] The outer wall of the fixed base 100 is provided with a first thread 110. At least two guide grooves 120 are formed along the axial direction of the cylindrical wall of the fixed base 100. The guide grooves 120 extend along the axial direction of the fixed base 100 and penetrate the end of the fixed base 100 away from the mounting surface. The number of guide grooves 120 can be two, three, or four, preferably two or four symmetrically distributed to ensure balanced force distribution. The cross-section of the guide grooves 120 is rectangular. The outer wall of the movable base 200 is provided with sliders 210 corresponding to the number and position of the guide grooves 120. The sliders 210 can be protrusions integrally formed with the movable base 200, or they can be independent parts assembled later and fixed by screws or clips. The shape of the sliders 210 matches the cross-section of the guide grooves 120, allowing them to be embedded in and slide along the guide grooves 120. The cooperation between the slider 210 and the guide groove 120 effectively restricts the circumferential rotation of the movable seat 200 relative to the fixed seat 100, while only allowing it to move linearly along the axial direction of the fixed seat 100, providing precise guidance for subsequent threaded drive.

[0036] Specifically, a second thread 211 is machined on the exposed surface of the slider 210 (i.e., the portion exposed on the outer wall of the movable seat 200), and the first thread 110 and the second thread 211 have overlapping meshing working areas in the axial direction, so that the internal thread 310 of the adjusting ring 300 can simultaneously mesh with the first thread 110 and the second thread 211. Specifically, in the embodiment shown in this application, the second thread 211 is flush with the first thread 110. The direction of rotation of the second thread 211 is the same as that of the first thread 110, for example, both are right-hand threads, or both are left-hand threads. Of course, the directions of rotation of the first thread 110 and the second thread 211 can be the same or opposite. When the directions of rotation are opposite, a differential thread mechanism is formed, which can achieve more precise fine-tuning or faster coarse-tuning. Its core is that the adjusting ring 300 drives the movable seat 200 by simultaneously meshing with two threads.

[0037] In some embodiments, the first thread 110 and the second thread 211 have different pitches, with the first thread 110 having a pitch of 2 mm and the second thread 211 having a pitch of 1.5 mm.

[0038] Of course, in other embodiments, the first thread 110 and the second thread 211 can be configured to have opposite directions of rotation.

[0039] The adjusting ring 300 is an annular component with a first internal thread 310 machined on its inner wall. The first internal thread 310 matches the first thread 110 and the second thread 211. The adjusting ring 300 is sleeved on the outside of the fixed base 100, and its first internal thread 310 engages with the first thread 110 on the outer wall of the fixed base 100, and its first internal thread 310 engages with the second thread 211 on the slider 210 of the movable base 200.

[0040] It should be noted that the cross-sectional shapes of the fixed base 100 and the movable base 200 described in this application should not be construed as limited to circles; they can be rectangular, polygonal, or other irregularly shaped structures adapted to the installation space. The "anti-rotation guide structure" is also not limited to the "guide groove 120-slider 210" fit; any structure that can restrict relative circumferential rotation between the movable base 200 and the fixed base 100 while allowing axial movement, such as splines, keyways, and flat keys, falls within the protection scope of this application.

[0041] When the extension position of the electrical end face needs to be adjusted, the operator rotates the adjusting ring 300. Since the adjusting ring 300 engages with the first thread 110 of the fixed base 100 via the first internal thread 310, the rotational motion drives the adjusting ring 300 to move axially along the fixed base 100. Simultaneously, since the first internal thread 310 of the adjusting ring 300 also engages with the second thread 211 on the slider 210 of the movable base 200, and the movable base 200 itself is restricted from rotation by the guide groove 120, the rotational motion of the adjusting ring 300 is converted into axial linear motion of the movable base 200 relative to the fixed base 100. The direction of rotation of the adjusting ring 300 determines whether the movable base 200 extends or retracts. For example, when all threads are right-handed, clockwise rotation of the adjusting ring 300 drives the movable base 200 to extend outwards, while counterclockwise rotation retracts it inwards.

[0042] This dual-thread coordinated drive design ensures a very smooth and precise adjustment process. Due to the self-locking nature of the threaded drive, the position of the movable seat 200 can be reliably maintained when the adjusting ring 300 is rotated without external force, preventing displacement caused by vibration or contact during use. This device achieves continuous, stepless, and precise adjustment, significantly increasing the adjustment range. During installation, installers can adjust the extension length of the movable seat 200 according to the thickness of the wooden board, ensuring that the electrical appliance remains flush with the outer surface of the board after installation. This avoids dust accumulation in depressions and eliminates the risk of bumps and knocks, greatly improving installation quality and aesthetics.

[0043] When driven, the adjusting ring 300 can move axially together with the movable seat 200 as shown in the previous embodiment, or it can be designed to be axially fixed (e.g., by an additional limiting structure) so that the adjusting ring 300 only rotates, making the second external thread 211 wider, and then driving the movable seat 200 to move independently through the thread pair of the internal thread 310 and the second external thread 211.

[0044] In some embodiments, the electrical mounting device further includes a mounting plate 400, which is vertically fixed to one end of the mounting base 100. A through hole 410 is formed on the mounting plate, aligned with the first channel. The diameter of the through hole 410 is larger than the inner diameter of the second channel and smaller than or equal to the inner diameter of the first channel. The mounting plate 400 is typically a rectangular or circular plate structure. The through hole 410 is located in the center of the mounting plate 400.

[0045] One end of the fixing base 100 is directly fixed to the mounting plate 400. In the embodiment shown in this application, the fixing base 100 and the mounting plate 400 are integrally formed, and the fixing base 100 and the through hole 410 are concentric. When it is necessary to install this electrical device on a wooden board, a hole is directly drilled in the wooden board, and then the mounting plate 400 is fixed to the inside of the wooden board so that the through hole 410 is aligned with the hole in the wooden board. After fixing, the end face of the electrical body is kept flush with the outer surface of the wooden board by rotating the adjusting ring 300.

[0046] It should be noted that for materials such as ceramic tiles and stone, the mounting plate 400 is usually bonded to the wall panel using a special adhesive, while for wood panels, the mounting plate 400 is directly fixed to the wall panel with screws.

[0047] In some embodiments, mounting holes are provided at the four corners of the mounting plate 400. When it is necessary to mount this application on a wooden board, the mounting plate 400 is placed against the back of the wooden board, and then screws are screwed into the mounting holes at the four corners of the mounting plate 400 to fix the mounting plate 400 to the wooden board.

[0048] The mounting plate 400 has a surface covered with radiating grooves 420 on the side facing away from the mounting base 100. These grooves 420 can be radial fine grooves or a mesh-like interlaced pattern. These grooves 420 increase the connection between the mounting plate 400 and the wood panel. When the mounting plate 400 is connected to the wall panel material with adhesive, the adhesive between the mounting plate 400 and the wood panel will be partially embedded in these grooves 420, forming a strong anchoring effect after drying, thus improving the reliability and stability of the installation.

[0049] Of course, if it needs to be installed on tiles, the mounting plate 400 does not need to be connected to the tiles with screws; it can be directly connected to the tiles with adhesive material.

[0050] In some embodiments, at least one set of mounting grooves is provided on the inner wall surface of the movable base 200. The mounting grooves can be straight grooves extending axially along the movable base 200, or inclined grooves or spiral grooves with a certain angle. Correspondingly, a mounting plate matching the shape and size of the mounting groove is provided on the outer wall of the electrical body 500 to be installed. During installation, simply align the mounting plate of the electrical body 500 with the mounting groove of the movable base 200, and then push or snap it in along a specific direction (usually axially or rotated by a certain angle) to achieve rapid positioning and fixation of the electrical body 500 in the movable base 200.

[0051] To ensure that the position of the movable seat 200 does not change during use after adjustment, this embodiment also includes a locking mechanism for locking the relative position of the movable seat 200 and the fixed seat 100 after adjustment.

[0052] In some embodiments, the locking mechanism includes a locking ring 600. The locking ring 600 is an annular part, which is sleeved on the outer wall of the fixed base 100. The inner wall of the locking ring 600 is machined with an internal thread 310 and a third thread 610, which matches the first thread 110 on the fixed base 100.

[0053] In the initial adjustment state, the locking ring 600 is rotated to a position away from the adjusting ring 300, without hindering the operation of the adjusting ring 300. After adjusting the movable seat 200 and its internal electrical components to the ideal position (i.e., the end face of the electrical components is flush with the outer surface of the wooden board) by rotating the adjusting ring 300, the operator can screw the locking ring 600 along the thread of the fixed seat 100 until it is tightened against the adjusting ring 300. In this way, the locking ring 600 can form a frictional constraint on the adjusting ring 300, thereby effectively preventing the adjusting ring 300 from rotating due to accidental force or long-term vibration, which would cause axial displacement of the movable seat 200.

[0054] In other embodiments, the locking mechanism may also be implemented as a tightening screw structure provided on the adjusting ring 300.

[0055] To prevent the movable seat 200 from accidentally detaching from the fixed seat 100 due to excessive rotation of the adjusting ring 300 during the adjustment process, this embodiment provides a limiting ring 900 on the fixed seat 100 at the end away from the mounting plate 400.

[0056] The outer diameter of the limiting ring 900 is larger than the outer diameter of the fixed base 100. The limiting ring 900 has a ring-shaped structure, and an annular groove 910 is provided on one side of the limiting ring 900. This annular groove 910 is directly fitted onto the fixed base 100 at the end away from the mounting plate 400 to achieve the limiting function. When the movable base 200 moves to the end of its slider 210, the limiting ring 900 will prevent the movable base 200 from moving further outward, thus playing a reliable mechanical limiting role. At the same time, the limiting ring 900 also prevents the adjusting ring 300 and the locking ring 600 from unscrewing off the fixed base 100.

[0057] In a preferred embodiment of this application, a conductive connection structure can be further provided between the fixed base 100 and the movable base 200. For example, a slip ring assembly or elastic contact can be provided between them, so that when the electrical appliance body is axially adjusted under the carrying of the movable base 200, it can always maintain a reliable electrical connection with the power line embedded in the wooden board. This design provides great convenience for intelligent electrical appliances that require power to operate (such as intelligent switches and sensors), realizing true "hot-swappable" and "wireless debugging" functions.

[0058] This application also provides an electrical appliance, which includes an appliance body 500, a limiting component 700, and an end plate 800. The appliance body 500 contains the electronic components and circuit boards necessary to realize its function, and its outer casing is designed to be accommodated in a movable base 200. The appliance body 500 is fixed in the electrical mounting device by engaging with the mounting slot of the movable base 200 via the aforementioned mounting plate.

[0059] The electrical appliance body 500 has a stepped groove 510 on its end face, and a first connecting hole 511 is formed on the stepped surface of the stepped groove 510. A lug 710 is provided in the middle of the limiting component 700, and a second connecting hole 711 is provided on the lug 710. A first insert plate 730 and a second insert plate 740 are respectively provided at both ends of the limiting component 700. A first slot 520 and a second slot 530 are provided on the side wall of the electrical appliance body 500, both of which are open slot structures. A third slot and a fourth slot are provided on the inner side wall of the movable seat 200, both of which are open slot structures. In the slotted structure, after the electrical body 500 is assembled in the movable base 200, the opening of the first slot 520 is aligned with the opening of the third slot, the opening of the second slot 530 is aligned with the opening of the fourth slot, the first insert plate 730 is inserted into the first slot 520 and the third slot, the second insert plate 740 is inserted into the second slot 530 and the fourth slot, the ear plate 710 is fitted in the stepped groove 510, the second connecting hole 711 is aligned with the first connecting hole 511, and the first connecting hole 511 and the second connecting hole 711 are connected by bolts to fix the ear plate 710 in the stepped groove 510.

[0060] The limiting component 700 is a U-shaped member, with an inwardly protruding ear plate 710 in its concave central part. The shape and size of the ear plate 710 match the stepped groove 510, and the ear plate 710 can be inserted into the stepped groove 510. A second connecting hole 711 corresponding to the first connecting hole 511 is provided on the ear plate 710.

[0061] During assembly, after the electrical body 500 is assembled in the movable base 200, the limiting component 700 is installed. The ear plate 710 of the limiting component 700 fits into the stepped groove 510 of the electrical body 500, and its first insert plate 730 is inserted into the first slot 520 and the third slot, and its second insert plate 740 is inserted into the second slot 530 and the fourth slot. Then, bolts are passed through the aligned first connecting hole 511 and the second connecting hole 711 and tightened, thereby firmly fixing the limiting component 700 to the electrical body 500. In this way, the limiting component 700 will be stuck between the electrical body 500 and the movable base 200, thereby preventing the electrical body 500 from rotating relative to the movable base 200 after it is installed in the movable base 200, further improving the firmness of the electrical body 500 in the movable base 200.

[0062] On the back of the end plate 800, a protruding retaining plate 810 is provided. The shape and size of the retaining plate 810 match the retaining groove formed by the aforementioned enclosure. When installing the end plate 800, simply align the retaining plate 810 on its back and push it into the retaining groove to achieve quick and secure engagement between the end plate 800 and the electrical body 500. This ensures that the end plate 800 will not easily loosen or fall off during use. Disassembly is also straightforward; simply pull the end plate 800 out of the retaining groove to separate it.

[0063] The end plate 800 is detachably connected to the electrical body 500. Specifically, the side wall of the electrical body 500 is provided with a slot 540, which is an open slot structure. The slot 540 extends along the axial direction of the electrical body 500. The limiting component 700 is provided with a notch 720, which is aligned with the opening of the slot 540. The end plate 800 is provided with a retaining plate 810, which is assembled between the slot 540 and the notch 720.

[0064] The end plate 800 has a tool opening 820 on its edge. When it is necessary to remove the end plate 800, simply insert a tool into the tool opening 820 to pry up the end plate 800.

[0065] The installation steps of this application are as follows: First, fix the mounting plate 400 to the back of the wooden board, as shown in Figure 8. Then, insert the electrical body 500 into the movable seat 200, as shown in Figure 9. Next, rotate the electrical body 500 so that the electrical body 500 and the movable seat 200 are snapped together. At this time, the first slot 520 is aligned with the third slot, and the second slot 530 is aligned with the fourth slot, as shown in Figure 10. Then, fix the limiting component 700 on the electrical body 500 so that the first insert plate 730 is inserted into the first slot 520 and the third slot, and the second insert plate 740 is inserted into the second slot 530 and the fourth slot, as shown in Figure 11. Finally, snap the end plate 800 on to complete the installation, as shown in Figure 12.
