DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 to Figure 5 In an embodiment of the utility model, an outdoor mechanical switch with a waterproof structure includes a shell 1, a button 2 is slidably connected to the top opening of the inner cavity of the shell 1, a pressing mechanism is provided at the bottom of the button 2, and a conductive mechanism is provided at the lower part of the inner cavity of the shell 1; the downwardly moving pressing mechanism is used to trigger the conductive mechanism to be energized, and the energized conductive mechanism is used to send an electrical signal to the controller; a blocking plate 5 protruding inwardly is integrally formed in the middle section of the inner wall of the shell 1, and the blocking plate 5 is used to provide support for the pressing mechanism; waterproof mechanisms are distributed on the blocking plate 5 and the pressing mechanism, and the waterproof mechanisms are used to prevent water from contacting the conductive mechanism.

[0027] In this embodiment: when pressing the mechanical switch, the button 2 is pressed by hand, and the pressed button 2 moves toward the inner cavity of the shell 1. At this time, the button 2 drives the pressing mechanism to move synchronously toward the inner cavity of the shell 1 until the pressing mechanism contacts the conductive mechanism. At this time, the power circuit is connected and an electrical signal is sent to the controller. After receiving the electrical signal, the controller can control the corresponding actuator to act, and the waterproof mechanism can further improve the waterproof performance of the mechanical switch to prevent water mist from entering the device and contacting the wire mechanism, causing the conductive mechanism to be insensitive.

[0028] Please refer to Figure 2The pressing mechanism includes a pressing rod 3 which is integrally formed with the bottom of the button 2. The pressing rod 3 extends to the bottom of the blocking plate 5, and the pressing rod 3 is slidably connected to the blocking plate 5. An upper spring 4 which is sleeved on the pressing rod 3 is provided between the top of the blocking plate 5 and the bottom of the button 2.

[0029] In this embodiment: when the button 2 is subjected to force, the button 2 drives the pressing rod 3 to move downward synchronously, and compresses the upper spring 4 at the same time. At this time, the upper spring 4 continues to exert its elastic potential energy.

[0030] Please refer to Figure 2 The conductive mechanism includes a guide rod 11 installed at the bottom end of the inner wall of the shell 1 and protruding upward. The outer wall of the guide rod 11 is slidably connected to an upper insulating plate 13. The upper insulating plate 13 is installed with two upper docking contacts 18 that penetrate to the bottom and are connected to the wire. A lower insulating plate 9 is fixedly installed at the bottom of the inner wall of the shell 1. Two lower docking contacts 10 that are aligned with the two upper docking contacts 18 in the upper and lower directions are installed at the top of the lower insulating plate 9. A lower spring 12 that is sleeved with the guide rod 11 is connected between the bottom end of the inner wall of the shell 1 and the bottom end of the upper insulating plate 13.

[0031] In this embodiment: during the downward movement of the pressing rod 3, the pressing rod 3 contacts the top of the upper insulating plate 13, and the upper insulating plate 13 is forced to move downward along the outer wall of the guide rod 11, and compresses the lower spring 12 until the upper docking contact 18 is connected to the lower docking contact 10. At this time, the power circuit is connected and an electrical signal is sent to the controller;

[0032] After the electrical signal is sent, the force applied to the button 2 is removed. At this time, the upper spring 4 and the lower spring 12 are reset synchronously, thereby driving the button 2 and the upper insulating plate 13 to reset. After the upper insulating plate 13 is reset to the highest position, it is blocked by the connecting plate 8 to achieve the purpose of stopping movement.

[0033] Please refer to Figure 4 and Figure 5 The waterproof mechanism includes an annular groove 19 which is formed at the bottom of the blocking plate 5 and is recessed upward. A waterproof plate 15 is slidably connected to the inner wall of the annular groove 19. Another waterproof plate 15 is slidably connected to the inner wall of the waterproof plate 15. The bottom of the waterproof plate 15 located at the most central position is connected to a limiting plate 6, and the limiting plate 6 is integrally formed with the outer periphery of the pressing rod 3. A sliding groove 17 is formed on the inner wall of the annular groove 19 and the inner wall of the waterproof plate 15. A slider 16 slidably connected to the sliding groove 17 is formed on the top of the outer wall of the waterproof plate 15, and the bottom end of the sliding groove 17 is a closed structure.

[0034] In this embodiment: when the pressing rod 3 moves up and down, the pressing rod 3 drives the limiting plate 6 to move synchronously, and the limiting plate 6 drives the waterproof plate 15 connected thereto and located at the most central position to move synchronously, and the waterproof plate 15 drives the slider 16 to move along the slide groove 17. When the slider 16 contacts the upper closed end or the lower closed end of the slide groove 17, the waterproof plate 15 drags the other waterproof plate 15 to unfold, thereby achieving that the upper and lower parts of the outer shell 1 are always in an isolated state, and achieving the purpose of preventing water mist from entering the lower half of the outer shell 1 and contacting the conductive mechanism.

[0035] Please refer to Figure 2 A connecting plate 8 is fixedly mounted on the inner wall of the housing 1 above the upper insulating plate 13 in the reset state, and a through hole 14 for inserting the pressing rod 3 is opened at the center of the connecting plate 8.

[0036] In this embodiment, when the pressing rod 3 moves downward, the pressing rod 3 passes through the through hole 14 and contacts the top of the upper insulating plate 13 .

[0037] Please refer to Figure 2 The bottom end of the pressing rod 3 is provided with an upwardly recessed receiving groove 7, and the pressing rod 3 moving downward drives the receiving groove 7 to be sleeved on the outer wall of the guide rod 11.

[0038] In this embodiment, when the pressing rod 3 moves downward, the accommodating groove 7 is sleeved on the outer wall of the pressing rod 3 to avoid movement interference between the two.

[0039] Please refer to Figure 4 and Figure 5 Sealing members are provided at the positions where the annular groove 19 contacts the waterproof plate 15 and the two waterproof plates 15 contact each other.

[0040] In this embodiment: the sealing ring further improves the sealing performance between the annular groove 19, the waterproof plate 15 and the adjacent waterproof plates 15, thereby enhancing the waterproof effect.
