Description

Technical Field

[0001] The present application relates to the field of electrical equipment, and in particular to a middle bracket structure for a wall switch socket. Background Art

[0002] European wall switches and sockets generally include a decorative panel, a middle plate, a reinforcement plate, and a functional base for power supply or on and off. The reinforcement plate, middle plate, and decorative panel are generally connected by snap fastening.

[0003] A Chinese patent with publication number CN203456654U discloses a mounting bracket structure for a wall switch socket, comprising a mounting bracket body formed by connecting at least two mounting brackets and a face cover matching the mounting bracket body; the mounting bracket is provided with a locking slot and a locking platform matching the locking slot; adjacent mounting brackets are connected by a connection structure in which the locking slot and the locking platform matching the locking slot are engaged; the shapes of at least two mounting brackets constituting the mounting bracket body are exactly the same, a buckle is formed on the face cover, and a buckle groove is formed on the mounting bracket body to be buckled and connected to the buckle.

[0004] The aforementioned wall switch and socket mounting bracket structure can achieve horizontal splicing and positioning through the cooperation of the locking grooves and locking platforms on the edges of the mounting bracket body. However, because the vertical side walls of the mounting bracket body have reserved locking grooves for the cover to snap into, the wall switches and sockets cannot be spliced ​​vertically. To install multiple wall switches and sockets vertically, the mounting bracket must be rotated, which will prevent the sockets from being properly positioned, resulting in poor aesthetics. Utility Model Content

[0005] In order to achieve multi-directional splicing, the present application provides a middle bracket structure for a wall switch socket.

[0006] The present application provides a middle bracket structure for a wall switch socket adopts the following technical solution:

[0007] A middle bracket structure for a wall switch socket, comprising a reinforcement frame and a middle plate fixedly connected to the outer surface of the reinforcement frame, a mounting hole being provided in the middle of the middle plate, the reinforcement frame comprising a support plate and a fixing frame fixedly connected to the bottom wall of the support plate, the side walls around the middle plate being connected with snap-in columns, the side walls of the middle plate being provided with snap-in holes for inserting the snap-in columns, a plurality of connecting protrusions being provided on the side of the middle plate facing away from the fixing frame, the plurality of connecting protrusions being respectively provided at the corners of the middle plate, the connecting protrusions comprising two snap-in portions, the snap-in portions being provided with a through hole, and a snap-in block for snapping a decorative panel being fixedly connected to the top wall of the snap-in portion close to the through hole.

[0008] By adopting the above technical solution, the middle plate is directly formed on the outer surface of the reinforcement frame to form an integral rigid frame, thereby effectively improving the structural strength. Multiple middle plates can be connected through snap-on columns and snap-on holes, and can be infinitely spliced ​​horizontally or vertically as needed. Different modular requirements can be achieved simply by connecting different decorative panels. The connecting protrusions at the corners provide stable connection points for the decorative panels of switches or sockets, so that the corners of the decorative panels can be stably fixed to the middle plate. When multiple middle plates are spliced ​​together, the buckle position moves from the edge of the middle plate to the inside of the middle plate, making way for the splicing position, so that the edges of the middle plates can abut against each other, and the layout of the middle plates after splicing can be more compact.

[0009] Optionally, the two buckle portions are perpendicular to each other along the midlines in the length direction.

[0010] By adopting the above technical solution, when the decorative panel is installed, when the buckle of the decorative panel is inserted into the through hole, the corners can be locked in three directions, thereby ensuring the stable connection of the decorative panel. The two buckle parts are used to resist the shear force in the vertical and horizontal directions respectively, which can effectively prevent the decorative panel from shaking.

[0011] Optionally, the support plate is provided with a fixing hole for inserting a fastener, and the middle plate is provided with a clearance hole facing the fixing hole, and the inner diameter of the clearance hole is larger than the inner diameter of the fixing hole.

[0012] By adopting the above technical solution, after the fasteners fix the middle plate to the wall, the ends of the fasteners will abut against the reinforcement frame, thereby preventing the fasteners from crushing the middle plate.

[0013] Optionally, the support plate is provided with a plurality of support holes.

[0014] By adopting the above technical solution, the middle plate can pass through the support hole during molding, and the inside of the middle plate can effectively abut against the inner wall of the support hole, so that the reinforcement frame is fixed inside the middle plate, thereby improving the connection strength.

[0015] Optionally, the connecting protrusion is provided with a plurality of grooves.

[0016] By adopting the above technical solution, when the decorative panel is inserted and buckled, the groove provides a certain deformation space for the inner wall of the through hole, thereby ensuring that the decorative panel can be stably buckled. In addition, the opening of the groove can effectively reduce the amount of material used, reduce the weight of the middle plate, and reduce production costs.

[0017] Optionally, a guide surface is provided on a side of the snap-fit ​​block close to the through hole.

[0018] By adopting the above technical solution, when the decorative panel is installed, the guide surface can effectively guide the clips of the installation panel to enter the through holes, thereby improving the installation efficiency.

[0019] Optionally, a guide block is connected to the top wall of the buckle part, and the guide block and the buckle block are located on two sides of the through hole respectively.

[0020] By adopting the above technical scheme, when the decorative panel is installed, the two sides of the buckle of the installation panel can be guided by the guide block and the guide surface respectively, so that the automatic alignment effect is realized, and the buckle is conveniently inserted into the through hole and buckled with the buckle block.

[0021] Optionally, the clamping column includes a fixed part and a connecting part fixedly connected between the fixed part and the side wall of the middle plate, and the width of the fixed part is greater than the width of the connecting part.

[0022] By adopting the above technical scheme, when the plurality of middle plates are connected, the fixed part can abut against the inner wall of the clamping hole, so as to ensure the stable connection between the adjacent middle plates.

[0023] Optionally, a plurality of positioning blocks are fixedly connected to the top of the side of the middle plate close to the installation hole.

[0024] By adopting the above technical scheme, the positioning blocks facilitate the positioning of the base and the insertion into the installation hole.

[0025] In summary, the present application has the following beneficial effects:

[0026] 1. By arranging the clamping column and the clamping hole on the side wall around the middle plate, the plurality of middle plates can be arbitrarily arranged in the horizontal direction and the vertical direction, so that the function and the number of the wall switch socket can be customized according to the demand.

[0027] 2. By arranging the connecting protrusion at the corner and inwardly retracting the buckling position, the buckling structure is given way to the clamping column and the clamping hole, so that the middle plate can be more compactly arranged. After the decorative panel is installed and buckled, the buckle can be limited in three directions, so as to ensure the connection strength. BRIEF DESCRIPTION OF DRAWINGS

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a middle bracket structure for a wall switch socket. Figure 1 、 Figure 2 The center support structure for a wall switch socket includes a center plate 2 and a reinforcement frame 1 disposed within the center plate 2. The reinforcement frame 1 includes a support plate 11 and a fixing bracket 12 fixedly connected to the bottom wall of the support plate 11. A mounting hole 21 is defined in the center of the center plate 2. The mounting hole 21 allows the base of the socket or switch to be inserted into the mounting hole 21. The reinforcement frame 1 is made of metal, while the center plate 2 is made of plastic and directly molded onto the outer surface of the reinforcement frame 1.

[0035] Reference Figure 2 、 Figure 3 , a plurality of positioning blocks 26 are fixedly connected to one side of the top wall of the middle plate 2 near the mounting hole 21, and the positioning blocks 26 are arranged along the outer edge of the mounting hole 21. The positioning blocks 26 can help the base of the switch or socket to be positioned, thereby facilitating installation.

[0036] Reference Figure 2 、 Figure 3 Four connecting protrusions 22 are provided on the side of the middle plate 2 facing away from the fixing frame 12. The four connecting protrusions 22 are respectively located at the corners of the middle plate 2. When the decorative panel of the switch or socket is installed, it can be snapped together with the connecting protrusions 22 at the corners, thereby improving the connection strength of the decorative panel. The connecting protrusion 22 includes two snap-on parts 221. The snap-on parts 221 are provided with through holes 222. A snap-on block 223 is fixedly connected to the top wall of the snap-on part 221 near the through holes 222. The two snap-on parts 221 allow the decorative panel to have multiple connection points with the connecting protrusions 22 after installation, further ensuring the stability of the snap-on. Since the connecting protrusions 22 are provided on the surface of the middle plate 2, the snap-on position is moved from the edge of the middle plate 2 to the inside of the middle plate 2. The through holes 222 cooperate with the snap-on of the decorative panel to limit the snap-on in three directions, thereby effectively ensuring the stable snap-on and improving the connection strength.

[0037] Reference Figure 2 、 Figure 3The connecting protrusion 22 is provided with a plurality of grooves 224. When the decorative panel's clip is inserted into the through-hole 222, the clip abuts against the snap-fit ​​block 223, causing the inner wall of the through-hole 222 to expand outward. The grooves 224 provide a space for deformation, ensuring that the clip can be properly inserted and locked into the through-hole 222. The provision of grooves 224 eliminates unnecessary material and reduces the weight of the entire outlet panel, thereby reducing raw material costs and production costs while maintaining structural strength.

[0038] Reference Figure 2 、 Figure 3 A guide surface 2231 is provided on the side of the buckle block 223 close to the through hole 222, so that when the decorative panel is installed, the guide surface 2231 can effectively guide the buckle of the installation panel to enter the through hole 222, thereby effectively improving the installation efficiency.

[0039] Reference Figure 2 、 Figure 3 A guide block 225 is fixedly connected to the top wall of the buckle portion 221. The guide block 225 and the locking block 223 are located on opposite sides of the through hole 222, and the guide block 225 is aligned with the guide surface 2231 of the locking block 223. When the decorative panel is installed, both sides of the buckle of the decorative panel can be guided by the guide block 225 and the guide surface 2231 at the same time, achieving an automatic alignment effect.

[0040] Reference Figure 2 、 Figure 3 The support plate 11 is provided with a plurality of support holes 112. When the middle plate 2 is formed on the outer surface of the reinforcement frame 1, the material is in a molten state. The material can pass through the support holes 112 and cool to plasticity, thus achieving effective fixation, making it difficult for the reinforcement frame 1 to move inside the middle plate 2, thereby effectively improving the connection strength.

[0041] Reference Figure 2 、 Figure 3 The support plate 11 is provided with a fixing hole 111 for inserting the fastener, and the middle plate 2 is provided with a clearance hole 23 corresponding to the fixing hole 111, and the inner diameter of the clearance hole 23 is larger than the inner diameter of the fixing hole 111. When the fastener fixes the middle bracket to the wall, the fastener will only come into contact with the reinforcement frame 1 and will not abut against the middle plate 2, so that the middle plate 2 will not be dented or damaged due to the squeezing of the fastener, thereby ensuring the integrity of the middle plate 2. At the same time, the end of the fastener away from the wall can be completely immersed in the clearance hole 23, thereby effectively saving space, so that after the decorative panel is installed, the switch and socket panel can be thinner. The clearance hole 23 close to the side of the fixing frame 12 is connected to the installation hole 21, so that the middle plate 2 can reduce the amount of material while not hindering the opening of the hook.

[0042] Reference Figure 2 、 Figure 3 and Figure 4 Multiple snap-in posts 24 are connected to the periphery of the middle plate 2 at even intervals. Several snap-in holes 25 for the snap-in posts 24 are also provided at even intervals around the periphery of the middle plate 2. Each sidewall of the middle plate 2 is provided with at least one snap-in hole 25 and one snap-in post 24. Multiple middle plates 2 can be connected via the snap-in posts 24 and snap-in holes 25, enabling unlimited horizontal or vertical splicing on the wall. Wall switches and sockets can be installed simply by replacing decorative panels of different sizes and styles. Because the snap-in position is moved inward to make way for the splicing position, there is no need to reserve snap-in space along the edges of the middle plates, allowing for a more compact layout when splicing.

[0043] Reference Figure 3 、 Figure 4 The clamping post 24 includes a fixing portion 241 and a connecting portion 242 fixedly connected between the fixing portion 241 and the side wall of the middle plate 2. The width of the fixing portion 241 is greater than the width of the connecting portion 242, and the width of the clamping hole 25 gradually increases radially toward the side of the mounting hole 21. After multiple middle plates 2 are spliced ​​together, the fixing portion 241 can abut against the inner wall of the clamping hole 25, thereby limiting the movement of a single middle plate 2 on a plane and ensuring a stable connection between adjacent middle plates 2.

[0044] The implementation principle of the middle bracket structure for a wall switch socket in the embodiment of the present application is: during installation, the fastener is passed through the fixing hole 111 to fix the middle plate 2 on the wall, and multiple middle plates 2 are spliced ​​through the snap-on holes 25 and the snap-on columns 24 as needed, and then the decorative panel is covered on the surface of the middle plate 2. The snaps of the decorative panel are inserted into the through holes 222 of the middle plate 2 and abut against the snap-on blocks 223. At this time, the four corners of the decorative panel are effectively fixed, thereby completing the installation.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
