[0028] The following Figure 1 - attached Figure 6 , the present application will be further described in detail.
[0029] Embodiment 1: A contactless waterproof distribution box, referring to Figure 1 、 Figure 2 , includes a box body 1 and a box door 2. On one side of the box body 1 close to the box door 2, an operation panel 3 is provided. On the operation panel 3, there are several switches 4 for controlling the circuit. A glass cover 5 is fixedly connected to the box body 1. The glass cover 5 sleeves the operation panel 3. An opening and closing structure 6 is provided on the glass cover 5. In addition, an activated carbon 10 for adsorbing water droplets formed by condensation in the glass cover 5 is installed in the glass cover 5.
[0030] On the side of the glass cover 5 away from the operation panel 3, several lever slots 12 corresponding to the number of switches 4 are opened. The lever slots 12 are strip-shaped. In addition, the opening and closing structure 6 includes several lever groups corresponding to the number of switches. Each lever group includes two levers 8 passing through the lever slots 12. At the same time, the levers 8 are in contact with the inner wall of the lever slots 12. The two levers 8 are respectively arranged on both sides of the switch 4 in the rotation direction. The staff can slide the levers 8 up and down along the lever slots 12 to control the opening and closing of the switch 4.
[0031] A sliding block 7 is fixedly connected to the side of the lever 8 away from the operation panel 3. A limiting plate 11 parallel to the surface of the side of the glass cover 5 away from the operation panel 3 is fixedly connected to the surface of the sliding block 7. When the lever 8 slides towards the operation panel 3, the sliding block 7 and the limiting plate 11 are in contact with the surface of the glass cover 5. One end of the lever 8 close to the operation panel 3 is fixedly connected with an anti-slip block 9. The anti-slip block 9 abuts against the surface of the switch 4 to increase the friction between the lever 8 and the surface of the switch 4.
[0032] A waterproof groove 13 is opened on the side wall of the lever slot 12. A waterproof plate 14 is slidably connected in the waterproof groove 13, and the waterproof plate 14 is in contact with the inner wall of the transverse side of the waterproof groove 13. Among them, the lever 8 passes through the waterproof plate 14. At the same time, the waterproof plate 14 slides along the waterproof groove 13 and the lever slot 12 under the drive of the lever 8. During the sliding process of the waterproof plate 14, the waterproof plate 14 always isolates the inside of the glass cover 5 from the outside.
[0033] A stabilizing groove 15 is opened between the waterproof groove 13 and the inner wall of the glass cover 5 on the side wall of the lever slot 12. A stabilizing plate 16 is slidably connected in the stabilizing groove 15. The transverse two sides of the stabilizing plate 16 are in contact with the inner wall of the transverse side of the stabilizing groove 15. Two through holes are opened on the stabilizing plate 16. The inner wall of the through holes is fixedly connected with a waterproof member 18. The lever 8 passes through the waterproof member 18 and then extends into the glass cover 5. The stabilizing plate 16 slides along the stabilizing groove 15 and the lever slot 12 under the drive of the lever 8. During the sliding process of the stabilizing plate 16, the stabilizing plate 16 always isolates the inside of the glass cover 5 from the outside. In addition, a return spring 17 is fixedly connected to the side of the stabilizing plate 16 away from the operation panel 3. The return spring 17 passes through the waterproof plate 14 and is fixedly connected with the sliding block 7.
[0034] The implementation principle of the embodiment of this application is as follows: The glass cover 5 sleeved on the operation panel 3 isolates the operation panel 3 from the outside world, effectively preventing the outside water droplets from wetting the operation panel 3 or depositing on the operation panel 3.
[0035] By sliding the slider 7 on the operation panel 3 along the opening and closing direction of the switch 4, the two levers 8 on the slider 7 are in contact with both sides of the end of the switch 4. At the same time, the slider 7 can further extend into the switch 4, increasing the mutual stress surface between the end of the switch 4 and the anti-slip block 9, which can facilitate people to control the opening and closing of the switch 4 by controlling the slider 7. And, during the process of the slider 7 extending into the switch 4, the limiting plate 11 can be used to prevent the slider 7 from approaching the glass cover 5 too much, resulting in the lever 8 damaging the switch 4.
[0036] In addition, when the slider 7 adjusts the switch 4 by approaching the glass cover 5, the return spring 17 will deform and contract under the action of the slider 7. After the switch 4 is adjusted, the return spring 17 deforms and elongates to reset the slider 7. And the return spring 17 connects the slider 7 and the glass cover 5 to prevent the slider 7 from falling off the glass cover 5.
[0037] At the same time, the waterproof plate 14 on the slider 7 can be used to prevent water droplets outside the two levers 8 from entering the glass cover 5. In addition, the waterproof part 18 on the stabilizing plate 16 can be used to prevent outside water droplets from flowing into the glass cover 5 along the lever 8.
[0038] When people control the opening and closing of the switch 4 through the opening and closing structure 6, the step of opening the glass cover 5 is omitted when opening and closing the switch 4, further avoiding the operation panel 3 from being wetted, and effectively preventing direct contact between the human body and the switch 4 on the operation panel 3 to prevent accidental electric shock. It should be noted that the parts such as the anti-slip block 9, the lever 8, and the slider 7 used to form the opening and closing structure 6 are all made of insulating materials, which can effectively avoid safety accidents caused by electric leakage of the operation panel 3.
[0039] Embodiment 2: A non-contact waterproof distribution box, refer to Figure 3 、 Figure 4 The difference between it and the above Embodiment 1 is that the opening and closing structure 6 includes a bow-shaped plate 19, and the bow-shaped plate 19 includes a long plate 1901 and two short plates 1902. The long plate 1901 is slidably connected to the glass cover 5 along the length direction. The length of the long plate 1901 is greater than the width of the glass cover 5, and a sliding groove 20 consistent with the length extension direction of the long plate 1901 is opened on the side of the glass cover 5 away from the box body 1, and the long plate 1901 is arranged in the sliding groove 20.
[0040] Two short plates 1902 are fixedly connected to both ends of the long plate 1901 and extend towards the box body 1, and the extension angle of the short plates 1902 is parallel to the upper or lower end face of the glass cover 5. On one side of the two short plates 1902 close to the glass cover 5, they are fixedly connected to the toggle levers 8, and the two toggle levers 8 respectively penetrate through the glass cover 5 along the opening and closing directions of the switch 4 and abut against the switch 4.
[0041] In addition, the number of the bow-shaped plates 19 with the above structure corresponds to the number of the switches 4 and is on the same straight line as the switches 4.
[0042] Pressing grooves 21 are formed on the upper and lower end faces of the glass cover 5, and the toggle levers 8 extend into the glass cover 5 through the pressing grooves 21. In addition, a waterproof member 18 is fixedly connected in the pressing groove 21, and the inner wall of the waterproof member 18 fits against the outer wall of the toggle lever 8.
[0043] On one side of the short plate 1902 close to the glass cover 5, a buffer member 22 is fixedly connected, and the buffer member 22 is specifically an elastic insulating rubber block.
[0044] Reference Figure 5 , a number of balls 23 are arranged in the glass cover 5, and the number of balls 23 is arranged along the inner walls of both sides in the length extension direction of the sliding groove 20, and the bow-shaped plate 19 slides along the length extension direction of the sliding groove 20 on the number of balls 23.
[0045] The implementation principle of the embodiment of the present application is that the opening and closing of the switch 4 can be controlled by pressing the short plates 1902 at both ends of the bow-shaped plate 19, and the operation is simple. At the same time, when pressing the bow-shaped plate 19 to control the opening and closing of the switch 4, the side of the buffer member 22 away from the short plate 1902 abuts against the glass cover 5, which can effectively prevent damage to the bow-shaped plate 19 or the glass cover 5 caused by excessive pressing force.
[0046] The waterproof member 18 is fixedly connected in the pressing groove 21 penetrated by the toggle lever 8 extending into the glass cover 5, which can effectively prevent external water droplets from entering the glass cover 5 along the length extension direction of the toggle lever 8 and causing the operation panel 3 to be wet.
[0047] In addition, when the bow-shaped plate 19 is pressed, it slides on the balls 23, which can reduce the friction between the glass cover 5 and the bow-shaped plate 19, and further facilitate people to press the bow-shaped plate 19 to control the opening and closing of the switch 4.
[0048] Embodiment 3: A touchless waterproof distribution box, reference Figure 6 , different from the above Embodiment 1 and Embodiment 2, the glass cover 5 is a frustum of a quadrangular pyramid, and the larger surface of the frustum of the quadrangular pyramid is fixedly connected to the box body, which can effectively avoid the deposition of water droplets on the glass cover 5.
