DETAILED DESCRIPTION
[0025] The embodiments of the present invention are described in detail below. Figures 1 to 8 The embodiment of the utility model provides a wiring box for facilitating wiring, comprising a box body 100, a first upper cover 200 and a second upper cover 300. Figure 1 and Figure 2 The box body 100 has a first cavity 120 and a second cavity 130, both of which have a top opening, and the first upper cover 200 and the second upper cover 300 are both connected to the top of the box body 100, and the first upper cover 200 is fixedly connected to the top of the box body 100 and closes the top opening of the first cavity 120, and the second upper cover 300 is rotatably connected to the first upper cover 200 and can close the top opening of the second cavity 130. A damping structure 400 is provided at the rotatable connection between the first upper cover 200 and the second upper cover 300, and the damping structure 400 is used to keep the second upper cover 300 in the current position when it is not subjected to external force. When wiring is needed, the user can flip open the second upper cover 300 to open the top opening of the second cavity 130. After opening to a certain position and stopping the cover opening action, the damping structure 400 can keep the second upper cover 300 in the current position without falling back naturally. At this time, the user can perform wiring operations. Therefore, the second upper cover 300 of the wiring box can be opened at different angles and can be kept in the current position, which can facilitate the user to connect the wires to prevent the second upper cover 300 from falling back naturally and affecting the wiring.
[0026] Further, refer to Figures 3 to 6The first upper cover 200 is provided with a transfer groove 210, and the second upper cover 300 is provided with a transfer protrusion 310. The transfer protrusion 310 is rotatably connected to the transfer groove 210, so that the second upper cover 300 can be rotated and opened relative to the first upper cover 200. Further, the inner wall of the transfer groove 210 and the outer wall of the transfer protrusion 310 are both arc surfaces, more specifically, circular arc surfaces. The transfer groove 210 and the transfer protrusion 310 have a certain length along the axis direction, so that the second upper cover 300 can rotate relative to the first upper cover 200 more smoothly. Furthermore, the first upper cover 200 is snap-connected to the box body 100, and the transfer protrusion 310 is connected to the box body 100 by a shaft screw. Specifically, the box body 100 includes a main body and a side cover ( Figure 1 The middle side cover is hidden), the shaft screw includes a threaded section and an optical axis section, the threaded section is threadedly connected to the adapter protrusion 310, and the optical axis section is rotatably connected to the side cover, so that the first upper cover 200, the second upper cover 300 and the box body 100 can be connected as a whole, and the second upper cover 300 can be smoothly rotated and opened, and after the shaft screw is screwed into the adapter protrusion 310 and the box body 100, a section located in the side cover of the box body 100 is the optical axis and has no thread. Therefore, when the second upper cover 300 is rotated to open or close, the shaft screw will rotate together with the second upper cover 300 relative to the first upper cover 200 and the box body 100, and will not cause the shaft screw to retreat, thereby ensuring that the second upper cover 300 can be connected to the box body 100 as a whole.
[0027] Further, refer to Figure 7 and Figure 8 , a first clamping structure 110 is provided on the side of the box body 100, and a second clamping structure 320 is provided on the side of the second upper cover 300, and the first clamping structure 110 can be clamped with the second clamping structure 320. After the transportation process and wiring are completed, the second upper cover 300 needs to be re-covered on the box body 100. At this time, the second upper cover 300 and the box body 100 are clamped with each other through the first clamping structure 110 and the second clamping structure 320 to achieve the covering and fixing of the second upper cover 300. Specifically, the first clamping structure 110 and the second clamping structure 320 are both hooks, and the two hooks are buckled together to achieve connection. Further, a handle 330 is provided on the side of the second upper cover 300 close to the second clamping structure 320, and the handle 330 protrudes outward from the side of the second upper cover 300. When the second upper cover 300 needs to be opened, the user can apply force to the handle 330 to bend the handle 330 outward, so that the second clamping structure 320 is separated from the first clamping structure 110, and after the limit between the second upper cover 300 and the box body 100 is released, the second upper cover 300 can be rotated to open. Figure 1, the inner wall of the second upper cover 300 is provided with an elastic sheet 340, and when the second upper cover 300 is closed and connected to the top of the box body 100, the elastic sheet 340 abuts against the inner side wall of the box body 100. The elastic sheet 340 is a structure that can undergo elastic deformation. When the second upper cover 300 is rotated to open, the elastic sheet 340 is not subjected to force and is in a naturally extended state. At this time, the free end of the elastic sheet 340 protrudes from the side of the second upper cover 300. When the second upper cover 300 is rotated to cover, the elastic sheet 340 is accommodated in the box body 100, and the free end will abut against the side wall of the box body 100, thereby realizing the clamping between the second upper cover 300 and the box body 100, and further improving the fixing effect between the second upper cover 300 and the box body 100. Of course, in some embodiments, the spring clip 340 can also be installed on the side wall of the box body 100, but when the spring clip 340 is installed on the second upper cover 300, after the second upper cover 300 is rotated to open, the spring clip 340 will also move away from the box body 100, thereby greatly avoiding the spring clip 340 from affecting the user's wiring operation in the box body 100.
[0028] Furthermore, in some embodiments, the inner wall surface of the transfer groove 210 and the outer wall surface of the transfer protrusion 310 can be set to a rough surface, for example, covered with a layer of uneven structural layer, so as to serve as a damping structure 400 to increase the friction resistance between the transfer groove 210 and the transfer protrusion 310. When the second upper cover 300 is rotated by applying force, the friction resistance can be overcome, so that the second upper cover 300 can be rotated smoothly. After the external force is removed, the second upper cover 300 can be maintained in the current position by the friction resistance between the transfer groove 210 and the transfer protrusion 310. In some embodiments, micro protrusions can also be set on the inner wall of the transfer groove 210 or the outer wall of the transfer protrusion 310, and the micro protrusions can be used to clamp and increase the friction force, so that the second upper cover 300 can be maintained in the current position.
[0029] In some other embodiments, the damping structure 400 includes a first protrusion 410 and a second protrusion 420. The first protrusion 410 protrudes from the inner wall of the transfer groove 210 and contacts the outer wall of the transfer protrusion 310. The second protrusion 420 protrudes from the outer wall of the transfer protrusion 310 and contacts the inner wall of the transfer groove 210. The first protrusion 410 and the second protrusion 420 can be positioned at different positions to achieve positioning and increase friction, so as to better enable the second upper cover 300 to remain in the current position. It should be noted that the first protrusion 410 and the second protrusion 420 are both small strip-shaped protrusions. For details, please refer to Figure 2 and Figure 3 , can provide a locking position and friction force, and the height of these tiny protrusions is very low, so even with the existence of the tiny protrusions, the transfer protrusion 310 and the transfer groove 210 can still maintain a rotatable connection. It should also be noted that although in Figure 1In the figure, there is a gap between the transfer protrusion 310 and the transfer groove 210, and there is also a certain gap between the first clamping structure 110 and the second clamping structure 320, but this is only to distinguish different structures in the drawings. In fact, these gaps are very small and can be ignored in actual products. Furthermore, the outer walls of the first protrusion 410 and the second protrusion 420 are both arc surfaces. When the second upper cover 300 rotates relative to the first upper cover 200, the first protrusion 410 will slide relative to the outer wall of the transfer protrusion 310, and the second protrusion 420 will slide relative to the inner wall of the transfer groove 210. The arc surface design can make the sliding smoother and will not produce scratches. Furthermore, the outer walls of the first protrusion 410 and the second protrusion 420 are both rough surfaces to increase friction and improve the damping effect.
