[0036] Example 1

[0037] Combination Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the installation structure of the present invention is schematically shown, including a middle frame 10, a mounting plate 20 and a bottom box 30.

[0038] The main structure of the middle frame 10 is in the shape of a circle, and the middle part thereof has a hollow structure 16. The middle frame 10 includes a bottom plate 10a and a side plate 10b connected to each other. The bottom plate 10a and the side plate 10b are perpendicular to each other, so that the cross section of the middle frame 10 is L-shaped, and the hollow structure 16 is arranged on the bottom plate 10a. After a cover made of transparent material such as glass is placed on the bottom plate 10a, the user can observe the indicator light, display screen and other display devices in the hollow structure 16 through the transparent cover. Therefore, the middle frame 10 can be used as an exterior decoration of the installation structure, and assume the functions of appearance decoration and external protection.

[0039] The mounting plate 20 has a front side and a back side, and core components such as a circuit board 50, a display screen, indicator lights, a power module, a data plug, etc. may be disposed on the front side and / or the back side of the mounting plate 20.

[0040] The base box 30 includes a connecting plate 30a in a circular shape and a receiving portion 30b connected to the connecting plate 30a. The receiving portion 30b has a receiving cavity 30c. The connecting plate 30a is arranged around the opening of the receiving cavity 30c. Existing cables, wiring devices, etc. can be arranged in the receiving cavity 30c. The connecting plate 30a is provided with a mounting hole, which can be fastened to the existing 86-type junction box by existing long screws.

[0041] In this embodiment, if Figure 5 The middle frame 10 is provided with a first snap 11 and a second snap 12, the number of the first snap 11 can be one or more, and the number of the second snap 12 can also be one or more. Correspondingly, the mounting plate 20 is provided with a first slot 21, the number of which is the same as the number of the first snap 11; the bottom box 30 is provided with a second slot 31, the number of which is the same as the number of the second snap 12.

[0042] The first buckle 11 is snapped into the first slot 21, so that the mounting plate 20 is snapped into the middle frame 10. Specifically, the front of the mounting plate 20 is arranged opposite to the inner wall surface of the bottom plate 10a of the middle frame 10, and the side of the mounting plate 20 is arranged opposite to the inner wall surface of the side plate 10b of the middle frame 10. The second buckle 12 is snapped into the second slot 31, so that the middle frame 10 is snapped into the bottom box 30. The second slot 31 is arranged at the edge of the connecting plate 30a of the bottom box 30, and the connecting plate 30a is located in the middle frame 10, so that the second buckle 12 and the second slot 31 are snapped into each other.

[0043] Based on the above structure, the installation and maintenance personnel can remove the middle frame 10 from the bottom box 30 without tools, and can also remove the mounting plate 20 from the middle frame 10 without tools, so as to facilitate the installation and maintenance of the components in the middle frame 10, the mounting plate 20 or the bottom box 30.

[0044] In this embodiment, the number of the second clips 12 is preferably four, wherein two second clips 12 and another two second clips 12 are respectively arranged on the inner wall surfaces of two side panels 10b arranged opposite to each other in the middle frame 10, thereby firmly buckling the middle frame 10 on the bottom box 30.

[0045] like Figure 8 In order to further limit the degree of freedom between the middle frame 10 and the bottom box 30, the middle frame 10 is provided with a limit block 15, and the limit block 15 is arranged in parallel with the second buckle 12. When the second buckle 12 is engaged with the second clamping groove 31, the end face of the bottom box 30 (especially the connecting plate 30a) abuts against the limit block 15. More specifically, the second clamping groove 31 is arranged at the edge of the connecting plate 30a, one side of the connecting plate 30a abuts against the limit block 15, and the other side of the connecting plate 30a is provided with the second clamping groove 31, and the inner wall surface of the second clamping groove 31 abuts against the second buckle 12. In addition to being used for limiting, the limit block 15 is also embedded in the process groove at the edge of the mounting plate 20, which can be used for dust prevention of the process groove.

[0046] Some products need to install components with heavier weight and / or higher cost on the mounting plate 20, which requires a more stable connection between the mounting plate 20 and the middle frame 10. Therefore, the mounting structure also includes a fastener 40, which can be a screw. The middle frame 10 is provided with a first connecting hole with an internal thread, and the mounting plate 20 is provided with a second connecting hole. The fastener 40 is passed through the first connecting hole and the second connecting hole, and the fastener 40 thereby stably connects the mounting plate 20 and the middle frame 10.

[0047] The middle frame 10 is provided with a second reinforcing rib 14 arranged opposite to the circuit board 50 on the mounting plate 20, the second reinforcing rib 14 abuts against the circuit board 50, and the second reinforcing rib 14 is respectively connected to the bottom plate 10a and the side plate 10b of the middle frame 10, which can improve the connection strength and rigidity between the bottom plate 10a and the side plate 10b. The second reinforcing rib 14 is L-shaped, one side of the circuit board 50 and the side edge of the circuit board 50 abut against the second reinforcing rib 14, and the second reinforcing rib 14 can limit the degree of freedom of the circuit board 50. In addition, a limiting column 18 is also provided on the bottom plate 10a of the middle frame 10, and a limiting hole 51 is provided on the circuit board 50, and the limiting column 18 is passed through the limiting hole 51, and the limiting hole 51 and the limiting column 18 can be used to limit the degree of freedom between the circuit board 50 and the middle frame 10. In addition, the limiting column can be set on the circuit board, the limiting hole is set on the middle frame, and the limiting column passes through the limiting hole, so that the structure of the circuit board is more stable.

[0048] Example 2

[0049] Combination Figures 1 to 8 As shown, the difference between this embodiment and embodiment 1 is that a notch 22 is provided at the edge of the mounting plate 20, and the notch 22 is arranged adjacent to the first card slot 21. When the mounting plate 20 is buckled into the middle frame 10, the notch 22 and the inner wall surface of the middle frame 10 form a nearly closed disassembly opening, and the installation and maintenance personnel can use fingers, keys or prying pieces to move the notch 22 through the disassembly opening to drive the mounting plate 20 to move relative to the middle frame 10, thereby forcing the first buckle 11 and the first card slot 21 to disengage from each other. Of course, in order to avoid damaging the electronic components on the circuit board 50 when using a key or prying piece to move the notch 22, the following measures can be taken: first, avoid setting electronic components on the circuit board 50 around the notch 22, and second, set the notch 22 at the edge of the mounting plate 20 where there is no circuit board 50 layout around it.

[0050] In this embodiment, if Figure 6There are two first card slots 21, and the two first card slots 21 are respectively located on both sides of the notch 22, so that when the notch 22 is pulled, the first card slots 21 on both sides can be driven to disengage from the corresponding first buckles 11. In order to facilitate the installation and maintenance personnel to more easily disassemble the middle frame 10 and the mounting plate 20, the first buckle 11 has a head end 111 and a tail end 112. The head end 111 of the first buckle 11 is arranged close to the disassembly port, and the tail end 112 of the first buckle 11 is arranged away from the disassembly port. The clamping area between the head end 111 of the first buckle 11 and the first slot 21 is smaller than the clamping area between the tail end 112 of the first buckle 11 and the first slot 21. For example, the first buckle 11 is a rectangular structure, and the head end 111 of the first buckle 11 is provided with an inclined surface. This inclined surface helps the head end 111 of the first buckle 11 to disengage from the first slot 21 earlier than the tail end 112 of the first buckle 11 when the notch 22 is pulled, thereby reducing the disengagement resistance of the first buckle 11 and the first slot 21.

[0051] In addition, if Figure 8 A first reinforcing rib 13 is provided in the middle frame 10 adjacent to the disassembly opening, and the first reinforcing rib 13 is respectively connected to the inner wall surface of the bottom plate 10a and the inner wall surface of the side plate 10b of the middle frame 10, so that the rigidity and strength of the middle frame 10 near the disassembly opening can be improved to prevent the middle frame 10 around the disassembly opening from being damaged when the installation and maintenance personnel use tools to disassemble the middle frame 10 and the mounting plate 20.

[0052] In other optional embodiments, a plurality of snap-fit ​​combinations consisting of a plurality of first snap-fit ​​grooves 21 and a plurality of notches 22 can be provided on the mounting plate 20, and the plurality of snap-fit ​​combinations are respectively provided on a plurality of edges of the mounting plate 20 to enhance the tightness of the connection between the mounting plate 20 and the middle frame 10.

[0053] Example 3

[0054] Combination Figure 4 , Figure 5 and Figure 7 As shown, the difference between this embodiment and embodiment 2 is that the edge of the mounting plate 20 is further provided with a third card slot 24, and the third card slot 24 and the first card slot 21 are respectively arranged on different edges of the mounting plate 20, and correspondingly, the inner wall surface of the side plate 10b of the middle frame 10 is provided with a third buckle 17, and the third buckle 17 and the first buckle 11 are respectively located on different side plates 10b of the middle frame 10, and the positions of the third buckle 17 and the third card slot 24 correspond, and the third buckle 17 is clamped to the third card slot 24. The third card slot 24 and the third buckle 17 can increase the connection points between the middle frame 10 and the mounting plate 20.

[0055] Example 4

[0056] like Figure 6The difference between this embodiment and the first embodiment is that a connection seat 23 is provided at a vertical position on the edge of the front side of the mounting plate 20, and a first card slot 21 is provided on the connection seat 23, so that the position of the first card slot 21 is closer to the direction facing the front side of the mounting plate 20, so that the space between the front side of the mounting plate 20 and the inner wall surface of the bottom plate 10a of the middle frame 10 is larger, so as to facilitate the installation of larger electronic components or other parts in the space between the front side of the mounting plate 20 and the inner wall surface of the bottom plate 10a of the middle frame 10.

[0057] To summarize, the first buckle 11 on the middle frame 10 is snapped into the first slot 21 of the mounting plate 20 to connect the middle frame 10 and the mounting plate 20, and the mounting plate 20 can be used to carry core components. The second buckle 12 on the middle frame 10 is snapped into the second slot 31 of the bottom box 30 to snap the middle frame 10 onto the bottom box 30. Based on the connection structure of the buckle and the slot, the installation and maintenance personnel can quickly and conveniently separate the middle frame 10 from the bottom box 30 to expose the core components on the mounting plate 20, which simplifies the disassembly and assembly process of the installation structure and realizes tool-free disassembly of the middle frame 10 and the bottom box 30. The middle frame 10 can also replace the exterior decoration in the traditional switch. The middle frame 10 combines the bearing function of the mounting plate 20 with the appearance decoration and protection function, so that the structure of the smart switch is further simplified and the structural integration is improved.
