Detailed Implementation
[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figures 1-4 This utility model provides an embodiment of an expandable surface-mounted four-port fast charging device, comprising an expansion shell 1, four socket shells 2 disposed on the inner wall of the expansion shell 1, each of the four socket shells 2 having a first socket 3 and a second socket 4 on its front side, a fixing member 5 fixedly connected to the left side of the inner wall of the expansion shell 1, bolts 6 threadedly connected to the four corners of the rear side of the fixing member 5, a rear shell 7 fixedly connected to the rear side of the left socket shell 2, a first connecting groove 8 evenly distributed on the top and bottom of the expansion shell 1, a buckle 13 slidably connected to the inner wall of the first connecting groove 8, a second spring 14 fixedly connected between two adjacent buckles 13, three second connecting grooves 9 disposed on the front side of the expansion shell 1, a first spring 12 fixedly connected to the front side of each of the three second connecting grooves 9, a push block 11 fixedly connected to the front side of each of the three first springs 12, a third connecting groove 10 disposed on the rear side of each of the three right socket shells 2, and a dustproof component disposed on the outer surface of the socket shell 2 for normal dust protection of the socket ports.
[0025] Specifically, during the use of the socket, when one of the three sockets on the right side is damaged while the others are working normally, by moving the top and bottom latches 13 of the expansion housing 1, the two adjacent latches move relative to each other and compress the second spring 14, causing the latches 13 to release from their engagement with the socket housing 2. The socket housing 2, under the elastic force of the first spring 12 on the rear side, pushes the push block 11 to push it out of the expansion housing 1, completing the disassembly. When reinstalling after repair, simply press the socket housing 2 backward, and the third connecting groove 10 pushes open the latches 13. The latches 13 then rebound through the second spring 14, engaging the socket housing 2, completing the reinstallation. This solves the problem of cumbersome disassembly and repair when one of the sockets malfunctions.
[0026] Reference Figure 5 The dustproof component includes a storage slot 20, which is located on the front side of the socket housing 2. A dustproof plate 15 is provided between the front and rear sides of the inner wall of the storage slot 20. Rollers 16 are fixedly connected to the four corners of the rear side of the dustproof plate 15. A partition 17 is fixedly connected to the front side of the dustproof plate 15. A first magnet 18 is fixedly connected to the top of the partition 17 and the front top of the storage slot 20. A second magnet 19 is fixedly connected to the bottom of the partition 17 and the front bottom of the storage slot 20.
[0027] Specifically, when using the socket, the dustproof plate 15 is moved upward by lifting the partition 17. The dustproof plate 15 moves up and down in the storage slot 20 by the rollers 16 at the four corners. When the dustproof plate 15 is lowered, the part of the bottom of the dustproof plate 15 that exceeds the partition 17 inserts into the bottom of the storage slot 20, completely covering the front side of the socket shell 2, thereby preventing dust and solving the problem that the fast charging port is prone to dust accumulation and plug damage when it is not used for a long time.
[0028] Reference Figure 1 and Figure 2 All four socket housings 2 are tightly fitted to the expansion housing 1, and the four socket housings 2 are completely inside the inner wall of the expansion housing 1.
[0029] Specifically, the left socket housing 2 is connected to the three right socket housings 2 in different ways, but after installation, they are all completely inside the inner wall of the expansion housing 1.
[0030] Reference Figure 3 and Figure 4 The buckle 13 fits tightly with the third connecting groove 10, and the front side of the push block 11 fits tightly with the rear side of the socket housing 2.
[0031] Specifically, after the buckle 13 returns to its original position by the elastic force of the second spring 14, the front part of the buckle 13 engages with the third connecting groove 10. After the socket housing 2 loses the fixation of the buckle 13, the push block 11 is pushed by the elastic force of the second spring 14, thereby pushing the socket housing 2.
[0032] Reference Figure 2 The bolt 6 is threaded through the fastener 5 and the left socket housing 2, and the left socket housing 2 is fixed to the extension housing 1 by the bolt 6.
[0033] Specifically, since the left socket needs to be fixed to the socket slot on the wall, the left socket housing 2 needs to be fixed to the expansion housing 1 in a different way so that it can be removed from the wall during overall maintenance.
[0034] Reference Figure 5 The outer surfaces of the four rollers 16 are tightly fitted to the left and right sides of the inner wall of the storage groove 20, and the four rollers 16 roll up and down in the storage groove 20.
[0035] Specifically, by setting rollers 16 around the dustproof plate 15, the dustproof plate 15 can move up and down more smoothly, preventing the dustproof plate 15 from getting stuck in the storage slot 20 and affecting its use.
[0036] Reference Figure 5 The two first magnets 18 are tightly fitted together, and the two second magnets 19 are tightly fitted together.
[0037] Specifically, when the dust cover 15 is lifted, the two first magnets 18 attract each other to prevent the dust cover 15 from falling. When the dust cover 15 is closed, the two second magnets 19 attract each other to allow the dust cover 15 to close by magnetic attraction even if it is not closed tightly.
[0038] Reference Figure 5 The front side of the dustproof plate 15 is tightly fitted to the front side of the inner wall of the storage slot 20, and the shape of the dustproof plate 15 completely covers the front opening of the storage slot 20.
[0039] Specifically, the dustproof plate 15 is larger than the groove on the front side of the socket housing 2, so that it can provide full dust protection when the dustproof plate 15 is closed.
[0040] Working principle: During the use of the socket, when one of the three sockets on the right side is damaged while the other sockets are working normally, by moving the top and bottom latches 13 of the expansion housing 1, the two adjacent latches move relative to each other and compress the second spring 14, causing the latches 13 to release from their engagement with the socket housing 2. The socket housing 2, under the elastic force of the first spring 12 on the rear side, pushes the push block 11 to push it out of the expansion housing 1, completing the disassembly. When reinstalling after repair, simply press the socket housing 2 backward. After the third connecting groove 10 pushes open the latches 13, the latches 13 rebound through the second spring 14 and engage with the socket housing 2, completing the reinstallation.
[0041] When using the socket, lifting the partition 17 causes the dustproof plate 15 to move upward. The dustproof plate 15 moves up and down in the storage slot 20 via the rollers 16 at the four corners. The attraction between the two first magnets 18 prevents the dustproof plate 15 from falling. When the dustproof plate 15 descends, the attraction between the two second magnets 19 allows it to close even if it is not fully closed. The part of the bottom of the dustproof plate 15 that extends beyond the partition 17 is inserted into the bottom of the storage slot 20, completely covering the front of the socket housing 2, thereby preventing dust.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
