DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figures 1 to 6 As shown, the distribution box in this embodiment includes a box body 1, a left door panel 3, a right door panel 4 and a locking mechanism 5; a box top 2 is arranged on the top of the box body 1, and the top surface of the box top 2 is arranged as an inclined surface. The advantage of the inclined surface is that when rain falls on the box top 2, it can slide down in time to avoid water accumulation. The side and bottom of the box body 1 are respectively provided with an inlet 7 for incoming lines and an outlet 10 for outgoing lines. The inlet 7 is a hollow tube structure, and its inner cavity is communicated with the inside of the box body 1. The outer end of the hollow tube structure is bent downward so that the outer end faces downward, which can prevent rainwater from entering the inside of the box body 1 through the inlet 10. The incoming line enters from the inlet 7 and is connected to the electrical appliance inside the box body 1, and the outgoing line is led out from the outlet 10 and is connected to the external line.

[0025] In this embodiment, the distribution box has a double-door structure with two openable door panels, namely the left door panel 3 and the right door panel 4. In this way, the door panels have a smaller opening radius and are more suitable for use in a relatively narrow space. The left door panel 3 and the right door panel 4 can be fully opened to facilitate the staff to open the door panels for various operations.

[0026] Specifically, the left door panel 3 and the right door panel 4 are installed on the box body 1 through concealed hinges 9. After the left door panel 3 and the right door panel 4 are closed, the concealed hinges are hidden inside the distribution box and cannot be seen from the outside, thereby increasing the aesthetics of the appearance of the distribution box; the right side of the left door panel 3 is provided with a pressing edge 31, and after the right door panel 4 is closed, its left edge presses the pressing edge 31; the locking mechanism 5 is installed on the right door panel 4, so that when closing the door panels, the left door panel 3 is closed first, and then the right door panel 4 is closed. After the right door panel 4 is closed, the right door panel 4 is locked by the locking mechanism 5, so that both the left door panel 3 and the right door panel 4 cannot be opened.

[0027] like Figure 4 and Figure 5 As shown, the locking mechanism 5 in this embodiment includes a handle 52, a rotating frame 54, a locking rod 57 and a counterweight 58. The rotating frame 54 can be rotatably installed on the right door panel 4. The handle 52 can be movably arranged at the outer end of the rotating frame 54. The locking rod 57 is arranged on the inner side of the right door panel 4 and is arranged along the height direction of the box body 1. The lower end of the locking rod 57 is connected to the inner end of the rotating frame 54. The upper end of the box body 1 is provided with a locking groove. When the rotating frame 54 rotates, the locking rod 57 is driven to move up and down. The right door panel 4 is locked by inserting the upper end of the locking rod 57 into the locking groove. The counterweight 58 is installed on the rotating frame 5 4, the counterweight 58 applies a torque to the rotating frame 54 to keep the locking rod 57 moving upward. Under the action of the counterweight 58, the locking rod 57 can keep matching with the lock slot, unless the handle 52 is manually turned to open, the locking state is stable and not easy to be opened by mistake; when the door panel needs to be opened, the handle 52 is rotated forcefully to drive the rotating frame 54 to overcome the resistance of the counterweight 58 and rotate, thereby driving the locking rod 57 to move downward and disengage from the lock slot, and then the right door panel 4 can be opened, and then the left door panel 3 can also be opened normally because the left door panel 3 loses the resistance limit of the right door panel 4. The counterweight 58 can be a metal block (such as an iron block, a stainless steel block) or a non-metal block (such as a concrete block or a stone block).

[0028] In some embodiments, Figure 2 and Figure 3 As shown, a magnetic block 8 is fixed on the bottom frame of the box body 1, and an iron piece is provided at the inner bottom of the right door panel 4. When the right door panel 4 is in a closed state, the magnetic block 8 is attracted to the iron piece, thereby keeping the left door panel 3 and the right door panel 4 in a closed state, avoiding the formation of gaps between the left door panel 3, the right door panel 4 and the box body 1.

[0029] In order to reduce the impact between the right door panel 4 and the left door panel 3 when closing, and to ensure that the right door panel 4 can effectively press and limit the left door panel 3 after closing, a soft rubber layer is provided between the left edge of the right door panel 4 and the pressing edge 31; the soft rubber layer can be made of rubber or silicone, and the soft rubber layer can be fixed at a corresponding position on the left door panel 3 or the right door panel 4. The left door panel 3 and the right door panel 4 can be made of plastic material or metal material (such as stainless steel).

[0030] Further, the locking mechanism 5 also includes a lock box 51 fixed on the right door panel 4, the rotating frame 54 is composed of a connecting rod 55 and a rotating shaft 56, the rotating shaft 56 is rotatably mounted on the lock box 51, the middle part of the connecting rod 55 is fixed on the rotating shaft 56, and the two ends of the connecting rod 55 are respectively connected to the lower end of the lock rod 57 and the counterweight 58, so that under the gravity of the counterweight 58, the end of the connecting rod 55 connected to the lock rod 57 will maintain an upward trend, thereby keeping the lock rod 57 in an upward movement trend, the handle 52 is inside the lock box 51 and connected to the outer end of the rotating shaft 56, the lock box 51 has an outward opening, and the middle part of the lock rod 57 is bent. Due to the existence of the lock box 51, there will be a large gap between the lock rod 57 and the inner side of the right door panel 4, which will increase the space occupied by the lock rod 57, so the middle part of the lock rod 57 is bent to make its upper part closer to the right door panel 4, saving the internal space occupied and improving the compactness of the structure. Specifically, when the lock box 51 is installed, an opening that passes through the inside and outside can be provided on the right door panel 4, and the lock box 51 is inserted into the opening and fixed.

[0031] In order to guide and limit the locking rod 57, Figure 5 As shown, a limiting sleeve 6 is also fixed on the inner side of the right door panel 4, and the locking rod 57 passes through the limiting sleeve 6. A limiting through hole for the locking rod 57 to pass through is provided on the limiting sleeve 6; the upper end of the locking rod 57 is preferably set to be conical to facilitate its insertion into the lock groove.

[0032] Furthermore, in order to enhance the locking effect, the handle 52 is rotatably connected to the outer end of the rotating shaft 56, and a buckle frame 53 with a padlock hole is fixed in the lock box 51. When the right door panel 4 is closed and the locking rod 57 is locked with the lock groove, the handle 52 is flipped over to be buckled with the buckle frame 53, and the padlock hole is exposed; in this way, after the handle 52 is buckled with the buckle frame 53, it can limit the rotating frame 54 and prevent accidental unlocking; on this basis, the handle 52 can also be effectively locked by installing a padlock in the exposed padlock hole, thereby preventing the locking mechanism from being opened by non-staff.

[0033] In order to improve the appearance of the distribution box, a cover plate 59 is movably installed at the opening of the lock box 51, and the cover plate 59 covers the handle 52 when in the closed state; specifically, the cover plate 59 can be rotatably installed on the lock box 51 through a pin shaft, and the cover plate 59 can be closed and opened by flipping.

[0034] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
