Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, specifically to an electrical appliance convenient installation structure and a lighting fixture. Background Technology

[0002] Electrical appliance installation structures are commonly used basic components in smart homes, security monitoring, and lighting systems, and are widely applied in various scenarios such as homes, commercial spaces, and industrial buildings. Their main function is to provide stable installation support for various devices and to protect internal wiring and modules.

[0003] A typical portable installation structure for electrical appliances includes a faceplate 2 and a chassis 1. The chassis 1 can be installed on a wall or other mounting surface, and the faceplate 2 can be installed on the chassis. The faceplate 2 is used to install core components of smart home, security monitoring, and lighting systems, such as lamps, cameras, and sensors. Figure 1 As shown, most portable appliance installation structures on the market currently use a threaded connection between the faceplate 2 and the base 1 for fixation. In actual installation, this method requires the installer to use a screwdriver or similar tool to align each threaded hole on the faceplate and base, and then tighten the screws clockwise to secure them. If a large number of portable appliance installation structures are involved, the installation process is not only cumbersome and requires a high level of skill from the installer, but also consumes a significant amount of time and effort. Furthermore, threaded connections are prone to problems such as stripped screws and misalignment during installation, leading to installation failure or affecting the sealing and stability of the portable appliance installation structure, increasing installation costs and maintenance difficulty. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a convenient electrical appliance installation structure that is easy to install. The limiting component improves the reliability of the connection between the snap-fit ​​part and the slot, and enhances the stability of the convenient electrical appliance installation structure during use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a convenient installation structure for electrical appliances, including a limiting component, a cover with an upward-facing opening, and a connecting plate located on the upper end of the cover. The outer edge of the connecting plate is provided with multiple snap-fit ​​components. Each snap-fit ​​component includes a plug and a slot, with a gap between the slot and the plug, the gap communicating with the slot. The upper end of the plug is connected to the outer edge of the connecting plate, and the lower end of the plug extends into the cover. The outer wall of the plug abuts against the inner wall of the cover. The slot is located on the upper surface of the outer edge of the connecting plate. The upper end of the cover extends into the corresponding slot with a snap-fit ​​portion, which snaps into the corresponding slot. The limiting component is connected to the inner wall of the cover and located within the gap. The limiting component is used to allow the plug to pass through and to prevent the plug from sliding within the gap.

[0006] Furthermore, the cover includes an outer periphery and a bottom plate connected to the lower end of the outer periphery, and the snap-fit ​​portion is connected to the upper end of the outer periphery.

[0007] Furthermore, the limiting component includes a housing, an elastic element, a slider, and a protrusion. The housing is connected to the base plate. The elastic element is disposed inside the housing. One end of the slider is disposed inside the housing and abuts against the elastic element. The other end of the slider protrudes out of the housing and abuts against the inner wall of the periphery. One end of the protrusion is connected to the end of the slider away from the housing. The other end of the protrusion extends through the outer sidewall. The upper end face of the slider is provided with a guide groove for the corresponding insertion block to slide. The guide groove communicates with the periphery and the gap.

[0008] Furthermore, the distance between the groove wall near the housing side and the periphery gradually shortens along the direction from the slot to the insert block located in the same snap-fit ​​assembly.

[0009] Furthermore, the bottom wall of the guide groove is triangular.

[0010] Furthermore, each of the snap-fit ​​components also includes an upward-facing sliding groove body, which is located on the upper end face of the outer edge of the connecting plate. One end of the sliding groove body communicates with the snap-fit ​​groove body, and the other end of the sliding groove body communicates with the gap.

[0011] Furthermore, the bottom wall of the slide body is inclined, and the side of the bottom wall of the slide body near the gap is inclined downward relative to the side of the bottom wall near the slot body.

[0012] Furthermore, the convenient installation structure for electrical appliances also includes a male conductive part and a female conductive part electrically connected to the male conductive part. The male conductive part is located inside the cover body, and the female conductive part is located on the lower end face of the connecting plate.

[0013] Furthermore, the upper end of the male conductive part is provided with multiple pin-shaped terminals, and the lower end surface of the female conductive part is provided with multiple guide rail grooves, and the pin-shaped terminals are engaged with the corresponding guide rail grooves.

[0014] This utility model also provides a lamp, including the aforementioned convenient electrical installation structure.

[0015] The beneficial effects of this utility model are as follows: The convenient electrical installation structure of this utility model is simple in structure and easy to install. During installation, when the snap-fit ​​part is aligned with the gap, the inner wall of the cover is slid upward along the outer wall of the insert, so that the insert is inserted into the cover. The outer wall of the insert abuts against the inner wall of the cover, achieving the initial positioning of the cover and the connecting plate. Then, the cover is driven to rotate relative to the connecting plate, causing the snap-fit ​​part to slide within the gap until it is snapped into the slot. At the same time, the insert is driven to pass through the limiting component, so that the limiting component is located within the gap, thereby preventing the insert from sliding towards the slot within the gap. The operation is simple. This utility model achieves relative fixation between the cover and the connecting plate through "the snap-fit ​​part snapping into the slot body" and "the insert abutting against the inner wall of the cover," ensuring the stability of its own structure. Then, with the help of the limiting component, the distance between the slot body and the insert is locked by the fixed insert, preventing the snap-fit ​​part from detaching from the slot body. This ensures the stability of the convenient electrical appliance installation structure after installation and prevents the cover from falling off or shifting due to external forces or other factors.

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figure 2-6 As shown, a convenient installation structure for electrical appliances includes a limiting component 3, a cover 1 with an upward-facing opening, and a connecting plate 2 located on the upper end of the cover 1. The connecting plate 2 is used for installation on a wall or other mounting surface. The outer edge of the connecting plate 2 is provided with multiple snap-fit ​​components. Each snap-fit ​​component includes a plug 21 and a slot 22. The plug 21 is located between the slot 22 within the same snap-fit ​​component and the slot 22 in another adjacent snap-fit ​​component. A gap 4 is left between the slot 22 and the plug 21. 22 are connected. The upper end of the insert 21 is connected to the outer edge of the connecting plate 2. The lower end of the insert 21 extends into the cover 1. The outer wall of the insert 21 abuts against the inner wall of the cover 1. The slot 22 is provided on the upper end face of the outer edge of the connecting plate 2. The upper end of the cover 1 extends into the corresponding slot with a snap-fit ​​part 13. The snap-fit ​​part 13 snaps into the corresponding slot 22. The limiting component 3 is connected to the inner wall of the cover 1 and is located in the gap 4. The limiting component 3 is used to allow the insert 21 to pass through and to prevent the insert 21 from sliding in the gap 4.

[0024] This utility model provides a convenient electrical installation structure. The structure is simple and easy to install. During installation, the connecting plate 2 is mounted on the wall. When the snap-fit ​​part 13 is aligned with the gap 4, the inner wall of the cover 1 slides upward along the outer wall of the insert 21, causing the insert 21 to be inserted into the cover 1. The outer wall of the insert 21 abuts against the inner wall of the cover 1, achieving initial positioning of the cover 1 and the connecting plate 2. At this time, the snap-fit ​​part 13 is located in the gap 4, and the limiting component 3 is located between two adjacent snap-fit ​​components, i.e., the limiting component 3 is located... Between the slot 22 of one snap-fit ​​assembly and the insert 21 in another adjacent snap-fit ​​assembly; then, drive the cover 1 to rotate relative to the connecting plate 2, causing the snap-fit ​​part 13 to slide within the gap 4 until it snaps into the slot 22, while simultaneously causing the insert 21 to pass through the limiting component 3, so that the limiting component 3 is located between the slot 22 and the insert 21 in the same snap-fit ​​assembly, thus ensuring that the limiting component 3 is located within the gap 4, preventing the insert 21 from sliding towards the slot 22 within the gap 4, making the operation simple. This utility model achieves relative fixation between the cover 1 and the connecting plate 2 by "the snap-fit ​​part 13 snaps into the slot body 22" and "the insert block 21 abuts against the inner wall of the cover 1", ensuring the stability of its own structure. Then, with the help of the limiting component 3, the distance between the slot body 22 and the insert block 21 is locked by fixing the insert block 21, preventing the snap-fit ​​part 13 from detaching from the slot body 22, ensuring the stability of the electrical appliance convenient installation structure after installation, and preventing the cover 1 from falling off or shifting due to external forces or other factors.

[0025] In this embodiment, the slot of the slot body 22 is opened on the upper end face and the side face of the outer edge of the connecting plate 2, that is, the slot body 22 is connected to the outer periphery 11, which facilitates the engagement of the engaging part 13 with the slot body 22 and also facilitates checking whether the engaging part 13 is engaged with the slot body 22.

[0026] In this embodiment, a plurality of the snap-fit ​​components are spaced apart along the outer edge of the connecting plate 2.

[0027] Furthermore, the cover 1 includes an outer periphery 11 and a bottom plate 12 connected to the lower end of the outer periphery 11. The snap-fit ​​part 13 is connected to the upper end of the outer periphery 11. Specifically, one end of the snap-fit ​​part 13 is connected to the upper end of the outer periphery 11, and the other end of the snap-fit ​​part 13 extends towards the axis of the connecting plate 2. The structure is simple and facilitates the snap-fit ​​part 13 to snap-fit ​​with the slot body 22.

[0028] Furthermore, the limiting component 3 includes a housing 31, an elastic element 34, a slider 32, and a protrusion 33. The housing 31 is connected to the base plate 12. The elastic element 34 is disposed inside the housing 31. One end of the slider 32 is disposed inside the housing 31 and abuts against the elastic element 34. The other end of the slider 32 protrudes out of the housing 31 and abuts against the inner wall of the periphery 11. One end of the protrusion 33 is connected to the end of the slider 32 away from the housing 31. The other end of the protrusion 33 protrudes through the side wall of the periphery 11. The upper end face of the slider 32 is provided with a guide groove 321 for the corresponding insertion block 21 to slide. The guide groove 321 communicates with the periphery 11 and the gap 4. That is, the groove opening of the guide groove 321 is opened on the upper end face of the slider 32 and on the two sides of the slider 32 facing the gap 4 and the periphery 11 respectively. The guide groove 321 is used to guide the insertion block 21 when it enters the slider 32 from one side to the other side. Specifically, the cover 1 is driven to rotate relative to the connecting plate 2, causing the insert 21 to slide along the gap 4 until it enters the guide groove 321 of the slider 32. At this time, the protrusion is pressed, causing the protrusion to move towards the housing 31 until a gap communicating with the guide groove 321 appears between the slider 32 and the periphery 11. The insert 21 passes through the gap and enters the other side of the slider 32 away from the slot body 22. Then the protrusion is released, and the protrusion is penetrated through the side wall of the periphery 11 by the force of the elastic element 34, so that the gap between the slider 32 and the periphery 11 disappears. The side wall of the slider 32 away from the slot body 22 abuts against the side wall of the insert 21. The slider 32 fixes the position of the insert 21, preventing the insert 21 from sliding in the gap 4, locking the distance between the slot body 22 and the insert 21, preventing the locking part 13 from disengaging from the slot body 22, and ensuring the stability of the connection between the locking part 13 and the slot body 22.

[0029] In this embodiment, the elastic element 34 is a spring, one end of which abuts against the inner wall of the housing 31, and the other end of which abuts against the slider 32.

[0030] Furthermore, the distance between the groove wall of the guide groove 321 near the housing 31 and the outer periphery 11 gradually shortens along the direction from the slot to the insert block 21 located in the same snap-fit ​​assembly. That is, the width of the guide groove 321 gradually shortens from the side near the gap 4 to the side away from the gap 4. With this arrangement, the groove width of the guide groove 321 is the largest at the opening on the side near the gap 4, which facilitates the entry of the slider 32 into the guide groove 321. The gradual shortening of the groove width from the side near the gap 4 to the side away from the gap 4 plays a guiding role, so that when a gap appears between the slider 32 and the outer periphery 11 that communicates with the guide groove 321, the insert block 21 is guided into the gap through the gradually shortening groove width of the guide groove 321. The structure is ingenious.

[0031] In this embodiment, the height of the insert 21 is greater than the distance from the connecting plate 2 to the slider 32, and less than or equal to the distance from the connecting plate 2 to the bottom wall of the guide groove 321, so that the limiting component 3 can prevent the insert 21 from sliding in the gap 4.

[0032] In this embodiment, the bottom wall of the guide groove 321 is triangular, with the longest side of the triangle located on the side of the bottom wall closer to the housing 31, and the other two sides located on the side of the bottom wall closer to the gap 4 and the side of the bottom wall closer to the periphery 11, respectively. That is, one end of the longest side of the triangle connects to the gap 4, and the other end connects to the periphery 11. When a gap appears between the slider 32 and the periphery 11 that communicates with the guide groove 321, the insert 21 enters the gap between the slider 32 and the periphery 11 from the gap 4 along the longest side of the triangle.

[0033] Furthermore, each of the snap-fit ​​components also includes an upward-facing sliding groove 23. The sliding groove 23 is located on the upper surface of the outer edge of the connecting plate 2. One end of the sliding groove 23 communicates with the snap-fit ​​groove 22, and the other end communicates with the gap 4. The sliding groove 23 facilitates the smooth entry of the snap-fit ​​part 13 into the snap-fit ​​groove 22 and its engagement with the snap-fit ​​groove 22. In this embodiment, the groove opening of the sliding groove 23 is located on the upper surface and side surface of the outer edge of the connecting plate 2, that is, the sliding groove 23 communicates with the outer periphery 11, making it easy to check whether the snap-fit ​​part 13 has smoothly entered the sliding groove 23.

[0034] Furthermore, the bottom wall of the slide body 23 is inclined, with the side of the bottom wall of the slide body 23 near the gap 4 inclined downwards relative to the side of the bottom wall near the slot body 22. That is, the distance between the bottom wall of the slide body 23 and the horizontal plane of the connecting plate 2 gradually shortens along the direction from the gap 4 to the slot body 22. This facilitates the quick entry of the locking part 13 into the slot body 22.

[0035] Furthermore, the convenient electrical installation structure also includes a male conductive part 5 and a female conductive part 6 electrically connected to the male conductive part 5. The male conductive part 5 is located inside the cover 1, and the female conductive part 6 is located on the lower end face of the connecting plate 2. The male conductive part 5 and the female conductive part 6 enable the convenient electrical installation structure to achieve electrical connection with other components (such as lamps) without complicated wiring operations, reducing installation difficulty and saving installation time.

[0036] Furthermore, the upper end of the male conductive part 5 is provided with a plurality of pin-shaped terminals 51, and the lower end face of the female conductive part 6 is provided with a plurality of guide rail grooves 61, wherein the pin-shaped terminals 51 are engaged with the corresponding guide rail grooves 61. In this embodiment, when the cover 1 rotates relative to the connecting plate 2, and the engaging part 13 engages with the slot body 22, the pin-shaped terminals 51 of the male end are accurately aligned with the guide rail grooves 61 on the female end. The cross-section of the guide rail grooves 61 is annular, and the rotation stroke is 10-15mm.

[0037] Furthermore, the aforementioned convenient installation structure for electrical appliances is suitable for chandeliers, ceiling lights, semi-ceiling lights, and wall lights, and has a wide range of applications.

[0038] This utility model embodiment also provides a lamp, including the electrical convenient installation structure described above and a light source assembly located inside the electrical convenient installation structure. Since the lamp of this embodiment includes all the technical features of the electrical convenient installation structure of the above embodiments, it also possesses all the technical effects of the electrical convenient installation structure of the above embodiments, which will not be repeated here.

[0039] Furthermore, in this embodiment, the light source assembly includes at least one of a chandelier, a ceiling light, a semi-ceiling light, or a wall light.

[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
