Technical Field
[0001] The utility model relates to the technical field of power switches, in particular to a switch closing and opening device for a power distribution box. Background Art
[0002] A distribution box is a device used for installing and connecting electrical appliances, protecting circuits, and distributing electric power. It is usually installed in the electrical system of a building or an industrial site to receive electric power from the main power supply or a generator and distribute it to various electrical or power-consuming devices. In order to control the on-off of the circuit, the distribution box is usually equipped with a closing and opening switch, which can control the on-off of the circuit manually or automatically.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] Referring to Figures 1-3 , an embodiment provided by the present invention: A switch opening and closing device for a power distribution box includes a first brake body 1 and a second brake body 2. A positioning groove 3 is opened inside the second brake body 2. A positioning column 4 is fixedly connected inside the first brake body 1. The outer wall of the positioning column 4 is slidably connected inside the positioning groove 3. First connecting frames 5 are fixedly connected to both the upper and lower sides of the first brake body 1. Second connecting frames 6 are fixedly connected to both the upper and lower sides of the second brake body 2. The first connecting frame 5 is slidably connected inside the second connecting frame 6. A rotating buckle one 7 is rotatably connected inside the second connecting frame 6. A rotating buckle two 8 is rotatably connected inside the first connecting frame 5. The rotating buckle two 8 and the rotating buckle one 7 are in contact with each other. Rotating rods 9 are rotatably connected to the outer walls of the rotating buckle one 7 and the rotating buckle two 8. A fixed block 10 is fixedly connected to one side of the rotating rod 9. A contraction assembly is provided inside the fixed block 10. The contraction assembly includes a first spring 13. One end of the first spring 13 is fixedly connected inside the fixed block 10. The other end of the first spring 13 is fixedly connected to a fixed ring 12. Fixed columns 11 are fixedly connected inside both the second connecting frame 6 and the first connecting frame 5. The fixed ring 12 is fixedly connected to the outer wall of the fixed column 11.
[0035] Specifically, when disassembling and assembling the switch, first insert the positioning post 4 in the first switch body 1 into the positioning slot 3 to ensure correct connection with the second switch body 2. Next, combine the first switch body 1 and the second switch body 2 together. At the same time, the first connection frames 5 on the upper and lower sides of the first switch body 1 will be inserted into the second connection frames 6. During this process, the rotating buckle two 8 is blocked by the second connection frame 6 and rotates, and the rotating buckle one 7 is also rotated accordingly due to the block of the first connection frame 5, so that the first connection frame 5 can smoothly move into the second connection frame 6. The movements of the rotating buckle one 7 and the rotating buckle two 8 will drive the rotating rod 9 on the outer wall to rotate, thereby affecting the movement of the fixed block 10. The fixed block 10 is forced to squeeze the connected first spring 13 to contract. When it moves to a certain position, the first spring 13 releases force and rebounds, causing the fixed block 10 and the rotating rod 9 to reset. At the same time, the rotating buckle one 7 and the rotating buckle two 8 return to their original positions and are stuck between the first connection frame 5 and the second connection frame 6, thus fixing the first switch body 1 and the second switch body 2. When disassembling, just rotate the rotating rod 9 to make the rotating buckle one 7 and the rotating buckle two 8 rotate to a parallel angle, and then take out the first connection frame 5 from the second connection frame 6 to complete the disassembly, which enables the switch to be quickly disassembled and assembled, improving the convenience and efficiency during maintenance.
[0036] Refer to Figures 4-6 , a protective cover 14 is provided on the outer wall of the first switch body 1. A rotating shaft 15 is provided at the top of the protective cover 14. A switch cover 16 is rotatably connected to the outer wall of the rotating shaft 15. A clamping rod 17 is rotatably connected to one side of the switch cover 16. A sliding groove 18 is opened inside one side of the clamping rod 17. A support block 19 is fixedly connected to one side of the second connection frame 6. A connection block 20 is fixedly connected to the outer wall of one side of the clamping rod 17. One end of a second spring 21 is fixedly connected inside the connection block 20, and the other end of the second spring 21 is fixedly connected inside the support block 19. A clamping block 22 is fixedly connected to one side of the protective cover 14.
[0037] Specifically, when the switch is not needed, the switch cover 16 can be rotated above the protective cover 14 and closed. During this process, the clamping rod 17 on one side of the switch cover 16 will contact the clamping block 22 on the protective cover 14. The clamping block 22 has an inclined surface, which causes the clamping rod 17 to rotate to one side under the force. At the same time, the movement of the clamping rod 17 will drive the stretching of the connection block 20 and the connected second spring 21. When the switch cover 16 and the protective cover 14 are completely closed, the force released by the second spring 21 will cause the connection block 20 to reset, resulting in the clamping rod 17 entering the inside of the clamping block 22, achieving the effect of quick connection and closing.
[0038] Refer to Figures 4-6, a sliding post 24 is slidably connected inside the clamping block 22. One end of the sliding post 24 is fixedly connected to an inclined surface slider 23. The inclined surface slider 23 is slidably connected inside the chute 18. A third spring 25 is sleeved on the outer wall of the sliding post 24. One end of the third spring 25 is fixedly connected inside the clamping block 22, and the other end of the third spring 25 is fixedly connected inside the inclined surface slider 23.
[0039] Specifically, at the same time, the clamping rod 17 will squeeze the inclined surface slider 23 inside the clamping block 22 to make it slide. At the same time, the movement of the inclined surface slider 23 will cause the connected third spring 25 to contract. When the clamping rod 17 reaches a certain position, the rebound of the third spring 25 will cause the inclined surface slider 23 to snap into the chute 18 inside the clamping rod 17, thereby locking the opening and closing cover 16 to prevent accidental opening when subjected to an external force, so as to achieve effective protection for the opening and closing operation. When it is necessary to open the opening and closing cover 16, just rotate the clamping rod 17 to drive the inclined surface slider 23 to retract.
[0040] Working principle: When it is necessary to disassemble and assemble the switching device, first insert the positioning post 4 inside the first switch body 1 into the positioning groove 3 to connect with the second switch body 2. Then, combine the first switch body 1 and the second switch body 2. At the same time, the first switch body 1 drives the first connection frames 5 connected to the upper and lower sides to insert into the second connection frames 6. During this process, the rotating buckle two 8 connected inside the first connection frame 5 is blocked by the inside of the second connection frame 6, and thus rotates. At the same time, the rotating buckle one 7 is also blocked by the first connection frame 5 and rotates, enabling the first connection frame 5 to smoothly move into the second connection frame 6. The rotating buckle one 7 and the rotating buckle two 8 drive the rotating rod 9 on the outer wall to rotate under force. The rotating rod 9 drives the fixed block 10 to move under force. The fixed block 10 squeezes the connected first spring 13 to contract. When it moves to a certain position, the first spring 13 releases force and rebounds, driving the fixed block 10 and the rotating rod 9 to return to their original positions, causing the rotating buckle one 7 and the rotating buckle two 8 to be rotated back to their original positions and stuck between the first connection frame 5 and the second connection frame 6, thus fixing the first switch body 1 and the second switch body 2. When disassembling, just rotate the rotating rod 9 to drive the rotating buckle one 7 to rotate to a parallel angle, and then take out the first connection frame 5 from the second connection frame 6, thereby achieving the effect of quickly disassembling and assembling the switching device. When the switching device is not in use, the opening and closing cover 16 can be rotated above the protective cover 14 to close it. During this process, the clamping rod 17 on one side of the opening and closing cover 16 contacts the clamping block 22 on one side of the protective cover 14. One side of the clamping block 22 is a slope, so that the clamping rod 17 will be forced to rotate to one side. At the same time, the clamping rod 17 drives the connecting block 20 on one side to move under force. The connecting block 20 drives the connected second spring 21 to stretch under force. When the opening and closing cover 16 and the protective cover 14 are closed, the second spring 21 releases force and pulls the connecting block 20 to return to its original position, and then the clamping rod 17 rotates into the clamping block 22. At this time, the clamping rod 17 squeezes the inclined plane slider 23 inside the clamping block 22 to slide it into the clamping block 22. At the same time, the inclined plane slider 23 drives the third spring 25 connected to one side to contract under force. When the clamping rod 17 reaches a certain position, the third spring 25 rebounds to drive the inclined plane slider 23 to snap into the chute 18 opened inside the clamping rod 17, thus fixing the opening and closing cover 16 and achieving the effect of protecting the switching device. When it is necessary to open the opening and closing cover 16, just rotate the clamping rod 17.
[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
