Description

Adjustment component and electrical device including the same Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to an adjusting component and an electrical device comprising the component. Background Art

[0002] A switch socket refers to a seat into which one or more circuit wiring can be inserted. Various wiring can be inserted through it, and the connection and disconnection between the circuit and the copper parts are used to ultimately achieve the connection and disconnection of that part of the circuit.

[0003] At present, electrical appliances such as switches and sockets used in walls have the following problems:

[0004] The area of ​​the groove on the wall needs to be smaller than the panel area of ​​the switches, sockets and other electrical appliances installed later. When the above-mentioned panels are installed, the groove on the wall needs to be covered. At the same time, the panels of the switches and sockets will protrude from the wall. The traditional panels protrude from the wall surface by a large area and are at least 4mm thick, which destroys the overall sense of the wall aesthetically and cannot meet the increasing demand for minimalism.

[0005] In actual applications, in order to achieve the goal of the socket panel and the wall finish surface being on the same level, a circle of grooves corresponding to the size and thickness of the panel will be opened around the wall opening where the socket panel is installed, and then conventional installation will be carried out. However, this installation method is time-consuming and labor-intensive. More importantly, the panel cannot be removed after installation, resulting in the inability to replace the internal electrical module if it is damaged.

[0006] Traditional socket panels are fixed with press-type clips. This fixing method makes the subsequent removal or replacement of the panel time-consuming and labor-intensive, which is not conducive to users' quick and convenient replacement, and therefore cannot flexibly match the increasing number of current decorative styles. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide an adjustment component and an electrical device including the component to solve one or more problems in the prior art.

[0008] To achieve the above object, the technical solution of the present invention is as follows:

[0009] An adjustment assembly includes a support frame, multiple studs, an embedded plate and a cover plate assembly. The proximal end of each stud is rotatably connected to the support frame, the distal ends of some of the studs abut against the embedded plates, and the distal ends of some of the studs abut against the cover plate assembly. By rotating the studs, the spacing of the cover plate assembly and / or the embedded plate relative to the support frame can be adjusted.

[0010] Furthermore, the stud includes a stud body, a proximal end of the stud body has a first hole, a distal end of the stud body has a first protrusion, and an outer side of the first protrusion has an external thread.

[0011] Furthermore, the outer diameter of the stud body is greater than the outer diameter of the first protrusion.

[0012] Furthermore, the support frame includes a support frame body, and the support frame body has a first opening, at least two threaded holes and at least one positioning hole.

[0013] Furthermore, the first opening edge has at least one guide plate, and the guide plate is formed to extend in a direction away from the embedded plate.

[0014] Furthermore, the cover assembly includes a cover body, on which at least one second hole and at least one first bayonet are provided, and the surface of the cover body has any one of an interface, a sensor, a brightness display element or a switch.

[0015] Furthermore, the proximal end of the cover body has an extension portion, and at least one second bayonet is provided on the extension portion.

[0016] Furthermore, the embedded plate includes an embedded plate body, on which a cover plate mounting hole and multiple positioning holes for installing the cover plate assembly are respectively opened, and a protrusion is provided on the edge of the hole opening of the cover plate mounting hole; multiple anti-crack holes and multiple fold line holes are opened on the embedded plate body.

[0017] An electrical device comprises the above-mentioned adjustment assembly and a module assembly connected to the cover assembly in the adjustment assembly. The module assembly has an installation box on the outside, and the installation box is fixedly connected to a support frame.

[0018] Furthermore, the electrical device also includes a panel, which is detachably arranged on the cover assembly; the shape of the panel is the same as the shape of the cover body in the cover assembly; the panel includes a panel body, and the surface of the panel body has at least one connecting portion that can be connected to the second bayonet and multiple third holes.

[0019] Compared with the prior art, the beneficial technical effects of the present invention are as follows

[0020] (1) The present invention provides a plurality of studs, and utilizes the rotatable studs to adjust the height of the studs relative to the support frame, thereby achieving adjustable spacing between the cover plate assembly and the embedded plate relative to the support frame. In addition, the first protrusions of each stud are the same length, so that the studs are always at the same plane height after being fixed, thereby ensuring the flatness of the cover plate assembly and the embedded plate and avoiding the problem of unevenness.

[0021] (2) Furthermore, by setting a first interface in the cover assembly, it can be used in different occasions. The first interface can be a socket interface or a hardware interface, or a brightness display element and a sensor can be used, which can provide a variety of connection methods to meet different hardware needs in different occasions.

[0022] (3) Furthermore, the setting of the embedded plate ensures that the panel and the wall surface are always in the same plane after the wall paint is applied. The wall paint around the panel will not be uneven due to the support of the embedded plate, and the protrusions set on the embedded plate can protect the edge of the hole of the cover plate installation hole, making it difficult to damage the edge of the hole when the panel is disassembled.

[0023] (IV) Furthermore, the panel is detachably provided on the cover assembly, so that during the disassembly process, the cover assembly can be removed by removing the panel and then loosening the screws, thereby allowing the module assembly to be quickly replaced.

[0053] Of course, in other embodiments of the present invention, the support frame body 100 may also be a shape other than a square, and the first opening 102 may also be any shape other than a square. The present invention does not make further limitations on this, as long as the support frame body 100 can be fixedly connected to the installation box 13 and the first opening 102 can cooperate with the module assembly 4.

[0054] Please refer to Figures 6 and 7, the specific structure of the cover assembly 5 is described in detail below:

[0055] The cover plate assembly 5 is connected to each stud 3 through fasteners. The cover plate assembly 5 includes a cover plate body 501. In the adjustment assembly described in the first embodiment, the cover plate body 501 is preferably circular, and at least one second hole 500 and at least one first bayonet 503 are provided on the cover plate body 501. A first interface 502 is provided on the surface of the cover plate body 501.

[0056] Specifically, please continue to refer to Figures 6 and 7. In the adjustment assembly described in this embodiment 1, there are four second holes 500, which are distributed at the top, bottom, left and right positions of the surface of the cover body 501. The first bayonet 503 is used to achieve a bayonet connection with the panel 8, wherein the first bayonet 503 includes a first bayonet portion 5030 and a second bayonet portion 5031. The area of ​​the first bayonet portion 5030 is different from the area of ​​the second bayonet portion 5031. Preferably, in the adjustment assembly described in this embodiment 1, the area of ​​the first bayonet portion 5030 is smaller than the area of ​​the second bayonet portion 5031.

[0057] Of course, in other embodiments of the present invention, the area of ​​the first bayonet portion 5030 may also be larger than the area of ​​the second bayonet portion 5031 , as long as it can be engaged with the panel 8 . The present invention does not impose any further limitations on this.

[0058] Further, please continue to refer to Figures 6 and 7. The side of the cover body 501 away from the panel 8, that is, the back of the cover body 501, has an extension portion 505. Specifically, the extension portion 505 is connected to the second protrusion 504 arranged on the back of the cover body 501. The extension portion 505 is extended and formed along the side away from the panel 8, and at least one second bayonet 506 is opened on the extension portion 505. Preferably, the second bayonet 506 is a square bayonet, and the second bayonet 506 is used to connect with the buckle on the outside of the module assembly 4.

[0059] Furthermore, the first interface 502 is preferably a socket interface, wherein the number of interfaces in the socket interface is not limited.

[0060] Please refer to Figures 1 and 10. The embedded plate 2 includes an embedded plate body 202. Preferably, in the adjustment component described in the first embodiment, the embedded plate body 202 is square, and the area of ​​the embedded plate body 202 is larger than the support frame 1. A cover plate mounting hole 205 and a plurality of second positioning holes 203 for installing the cover plate assembly are respectively provided on the embedded plate body 202, and a protrusion 204 is provided on the edge of the hole opening of the cover plate mounting hole 205.

[0061] Specifically, referring to Figure 10 , the cover plate mounting hole 205 is provided at the center of the embedded plate body 202. The cover plate mounting hole 205 is preferably circular, having the same shape as the cover plate assembly 5. A second positioning hole 203 is also provided on the embedded plate body 202 around the outside of the cover plate mounting hole 205. A fastener, i.e., a screw 6, can pass through the second positioning hole 203 to connect with the first hole 301 of the stud 3, thereby securing the embedded plate 2 to the stud 3. Continuing to refer to Figure 10 , the protrusion 204 is formed at the distal end of the embedded plate 2. The protrusion 204 is formed around the edge of the cover plate mounting hole 205 and protrudes from the surface of the embedded plate 2. The provision of the embedded plate 2 ensures that the wall paint layer is flush with the panel 8 after application. Furthermore, the protrusion 204 provided on the embedded plate 2 protects the edge of the cover plate mounting hole 205, making it less susceptible to damage when the panel 8 is removed.

[0062] Furthermore, the embedded plate body 202 is provided with a plurality of crack prevention holes 200 and a plurality of folding holes 201. When two or more module assemblies 4 are installed adjacent to each other, to prevent overlapping thicknesses of adjacent embedded plate bodies 202, the overlapping areas can be broken off and removed along the folding holes 201, thereby maintaining coplanarity and continuity between adjacent embedded plate bodies 202. Furthermore, the crack prevention holes 200 increase the adhesion area of ​​the putty layer, preventing cracking later.

[0063] Correspondingly, the present invention also provides an electrical device, as shown in Figures 3 and 8 . The electrical device includes the aforementioned adjustment assembly and a module assembly 4 connected to the cover assembly in the adjustment assembly. Specifically, the module assembly 4 is fixed to the cover body 501 in the cover assembly 5 via a second bayonet 506 and a snap connection. To protect the module assembly 4 from the external environment and to prevent dust, a mounting box 13 is provided on the outside of the module assembly 4. The mounting box 13 is threadedly connected to a screw 7. The screw 7 passes through the first positioning hole 103 of the support frame 1 and is fixedly connected to the threaded hole inside the mounting box 13, thereby securing the mounting box 13 to the support frame 1.

[0064] Further, please continue to refer to Figures 3 and 8. The panel 8 is detachably arranged on the cover assembly 5. Specifically, the panel 8 is disassembled and fixed by rotation, that is, when the panel 8 is rotated to a certain angle along the first direction, it is fixed to the cover body 501. When the panel 8 is selected to a certain angle along the second direction opposite to the first direction, it is unlocked from the cover body 501. In this embodiment, the first direction can be clockwise, and the second direction is counterclockwise. Similarly, in other embodiments of the present invention, the first direction can also be counterclockwise, and the second direction can be clockwise.

[0065] Further, please continue to refer to Figure 8. In order to achieve full coverage of the panel 8 and the cover body 501, the shape of the panel 8 is the same as the shape of the cover body 501 in the cover assembly 5.

[0066] Specifically, referring to Figure 9 , the panel 8 includes a panel body 800. The surface of the panel body 800 has at least one connecting portion 802 that can be connected to the second bayonet 506. The connecting portion 802 is hook-shaped and is used to engage with the first bayonet 503. A third hole 801 having the same shape as the first interface 502 is defined in the panel body 800. In the adjustment assembly described in this first embodiment, the first interface 502 is preferably a socket interface, and the shape of the third hole 801 matches the socket interface.

[0067] The specific installation process of the present invention is as follows:

[0068] Please refer to Figures 1 to 9. During the actual installation process, the installation box 13 is first installed in the slot of the wall, and then the support frame 1 is connected to the installation box 13. Specifically, the screw 7 passes through the first positioning hole 103 of the support frame 1 and is connected to the threaded hole inside the installation box 13 to achieve the fixed position of the support frame 1 on the installation box 13. After measuring the distance from the support frame 1 to the surface to be completed, some studs 3 are installed on the support frame 1. The studs 3 can be screwed to a fixed stroke through the external thread 303. When the studs 3 are tightened, the distance between the upper surface of each stud 3 and the support frame 1 is consistent, that is, each stud 3 is maintained at the same plane height. If ordinary screws are used, the height or stroke cannot be guaranteed, which will cause the panel to be uneven after subsequent installation.

[0069] Further, please continue to refer to Figures 1 to 9. The stud 3 installed on the support frame 1 is connected through the first hole 301, the screw 6 and the second hole 500 of the cover assembly 5, thereby realizing the connection between the cover assembly 5 and the support frame 1. At the same time, the second bayonet 506 of the cover assembly 5 passes through the first opening 102 and is clamped and fixed with the module assembly 4, and the module assembly 4 is connected to the wires in the installation box 13.

[0070] Further, please continue to refer to Figures 1 and 9, continue to install the stud 3 on the remaining threaded hole 101 of the support frame 1, the stud 3 is threadedly connected to the threaded hole 101 through the external thread 303, and then the embedded plate 2 is fixed to the support frame 1 by the screw 6. At this time, the anti-cracking net is installed on the surface of the embedded plate 2, and then the panel 8 is fixed to the cover assembly 5. The panel 10 is glued to the handle with nano glue, so that the operator can hold the panel 10 by the handle. Since there is a first bayonet 503 on the cover body 501, the first bayonet 503 can be engaged with the connecting part 802 of the panel 8. By rotating the panel 8 clockwise, the connecting part 802 of the panel 8 can be rotated to the first bayonet part 5030 and locked. Conversely, when the panel 8 is rotated counterclockwise, the connecting part 802 is rotated to the second bayonet part 5031, so that the panel 8 can be unlocked from the cover body 501. Finally, after applying protective paper on the surface of panel 8, putty can be applied on the surface of anti-cracking net, and wall paint can be applied after the putty is dry. After the wall paint is dry, the wall paint can be polished to expose the protective paper. After the protective paper is torn off, the surface of the panel is on the same surface as the wall. Example 2:

[0071] Most of the structures of Example 2 are the same as those of Example 1, except that the structures of the cover assembly 5 and the panel 8 are different. The first interface 502 in the cover assembly 5 adopts a hardware interface, specifically a USB interface 900. Therefore, the shape of the third hole 801 in the panel 8 corresponds to the USB interface 900, and the opening size of the third hole 801 is also the same as that of the USB interface 900. Example 3:

[0072] Most of the structures of Example 3 are the same as those of Example 1, except that the structures of the cover assembly 5 and the panel 8 are different. The first interface 502 in the cover assembly 5 adopts a hardware interface, specifically a network cable interface 1000. Therefore, the shape of the third hole 801 in the panel 8 corresponds to the network interface, and the opening size of the third hole 801 is also the same as that of the network cable interface 1000. Example 4:

[0073] Most of the structures of Example 4 are the same as those of Example 1, except that the structures of the cover assembly 5 and the panel 8 are different, wherein the first interface 502 in the cover assembly 5 is replaced by a sensor 11, specifically preferably a human presence sensor, and the panel 8 does not have the third hole 801 and adopts a smooth surface design, which covers the outside of the sensor 11 to play a protective role. Embodiment 5:

[0074] The fifth embodiment has the same structure as the first embodiment for the most part, except that a brightness display element 12, such as a night light, can be added to the cover assembly 5, and then the panel 8 is covered on the periphery of the cover assembly 5 with only the brightness display element 12 exposed.

[0075] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
