DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] A distribution box panel, comprising a panel frame 1 and a loose-leaf panel 2, wherein the loose-leaf panel 2 is rotatably arranged in a groove of the panel frame 1 through a rotating shaft 3, the panel frame 1 is fixed to a wall surface through a pair of locking bolts 4 and a pair of limiting bolts 5, and a limiting mechanism is arranged between the rotating shaft 3 and the panel frame 1;

[0027] The limiting mechanism includes a first magnet 6, a second magnet 7, a connecting rod 8, a guide rod 9 and a connecting seat 10. The connecting seat 10 is arranged inside the panel frame 1, the first magnet 6 is fixed to the surface of the rotating shaft 3, one end of the connecting rod 8 is fixed to the surface of the connecting seat 10, one end of the guide rod 9 is fixed to the surface of the second magnet 7, and the other end of the guide rod 9 is elastically movably arranged in the connecting rod 8. The first magnet 6 and the second magnet 7 are in contact with each other, and the polarities of the contact surfaces of the first magnet 6 and the second magnet 7 are opposite. When the loose-leaf board 2 is covered on the groove of the panel frame 1, the loose-leaf board 2 and the panel frame 1 are located on the same arc surface, and the rotation angle range of the loose-leaf board 2 through the rotating shaft 3 is 0° to 70°.

[0028] See also Figure 1 , 2and 3. the loose-leaf board 2 can rotate on the surface of the panel frame 1 through the rotating shaft 3. The rotating shaft 3 can drive the first magnet 6 to rotate synchronously when rotating. When the loose-leaf board 2 is in an open state, the rotating shaft 3 just drives the first magnet 6 to rotate to a state perpendicular to the horizontal plane. At this time, the first magnet 6 and the second magnet 7 will attract each other. Since the first magnet 6 cannot move laterally, the magnetic force between the first magnet 6 and the second magnet 7 can adsorb the second magnet 7 to move in the direction close to the first magnet 6. Since the connecting rod 8 and the guide rod 9 are elastically connected, the second magnet 7 can drive the guide rod 9 to move synchronously when moving and cause the elastic member between the connecting rod 8 and the guide rod 9 to deform and store energy. This elastic member is generally a spring, and under the action of the magnetic force, the first magnet 6 can also remain in a vertical state and not move, thereby realizing the limitation of the loose-leaf board 2. After closing the loose-leaf board 2, the first magnet 6 is detached from the surface of the second magnet 7, and the magnetic force between the first magnet 6 and the second magnet 7 disappears. The spring can drive the guide rod 9 to reset under the action of its own elastic force, thereby resetting the second magnet 7.

[0029] Embodiment 2:

[0030] The above scheme realizes the fixation of the loose-leaf panel 2 in the open state by the mutual adsorption of the first magnet 6 and the second magnet 7. In the present embodiment, in order to prevent the user from forgetting to confirm the closed state of the switch when disassembling the panel frame 1, an annular groove 11 is provided on the surface of the locking bolt 4, and a locking mechanism matching the annular groove 11 is provided between the second magnet 7 and the connecting seat 10. The locking mechanism includes a limit plate 12, a traction shaft 13 and a driving plate 14. The top end of the driving plate 14 is fixed to the surface of the second magnet 7. The guide shaft 13 is rotatably arranged between the connecting seat 10 and the panel frame 1, the bottom end of the driving plate 14 is slidably arranged on the surface of the traction shaft 13 through a guide member, one end of the limit plate 12 is fixed to the surface of the traction shaft 13, the guide member includes a spherical protrusion 15 arranged inside the driving plate 14, and a guide groove 16 arranged on the surface of the traction shaft 13, the spherical protrusion 15 is slidably arranged inside the guide groove 16, the guide groove 16 is spirally distributed on the surface of the traction shaft 13, and the projection of the guide groove 16 on the end face of the traction shaft 13 is an arc with a central angle of 90°.

[0031] See also Figure 3 , 4When the first magnet 6 and the second magnet 7 are attracted to each other, the second magnet 7 can drive the bottom of the driving plate 14 to move linearly on the surface of the traction shaft 13. Since the driving plate 14 can drive the spherical protrusion 15 to move linearly all the time, the spherical protrusion 15 always moves along a straight line inside the guide groove 16. However, the guide groove 16 is spirally distributed, so the guide groove 16 can drive the traction shaft 13 to rotate unidirectionally. When the first magnet 6 and the second magnet 7 are completely attracted and fitted, the spherical protrusion 15 just moves to the end of the guide groove 16, and at this time the traction shaft 13 just rotates 90°, so that the bottom end of the limit plate 12 can be moved out of the annular groove 11. At this time, there is no structure that can limit the locking bolt 4, and the loose-leaf panel 2 is in an open state. Therefore, the user can quickly confirm the state of the switch at this time, thereby improving the safety of disassembling the panel frame 1.

[0032] Working principle: when opening the loose-leaf board 2, it is necessary to flip the loose-leaf board 2 upwards, and the loose-leaf board 2 can rotate on the surface of the panel frame 1 through the rotating shaft 3. When the rotating shaft 3 rotates, it can drive the first magnet 6 to rotate synchronously. At this time, the first magnet 6 and the second magnet 7 will attract each other. When the second magnet 7 moves, it can drive the guide rod 9 to move synchronously and make the spring between the connecting rod 8 and the guide rod 9 deform and store energy, and the first magnet 6 will also absorb the second magnet 7 to keep it fixed, thereby realizing the limit of the loose-leaf board 2 at this time, and it can keep the suspended state motionless. When the loose-leaf board 2 is closed, the first magnet 6 is separated from the surface of the second magnet 7, and the magnetic force between the first magnet 6 and the second magnet 7 disappears, which will not affect the normal closing of the loose-leaf board 2.

[0033] When inspecting the switch and the line, it is necessary to open the loose-leaf panel 2 first. At this time, the first magnet 6 can drive the second magnet 7 to move horizontally, and the second magnet 7 can drive the driving plate 14 to move linearly on the surface of the guide rod 9. When moving, the driving plate 14 can drive the traction shaft 13 to rotate unidirectionally as a whole through the cooperation of the spherical protrusion 15 and the guide groove 16, so that the traction shaft 13 drives the limit plate 12 to rotate synchronously, so that the bottom of the limit plate 12 is moved out from the inside of the annular groove 11, so as to facilitate the disassembly of the locking bolt 4, thereby realizing the disassembly of the panel frame 1 as a whole. Since the loose-leaf panel 2 is in an open state at this time, the user can easily confirm the closed state of the switch, thereby improving the safety when disassembling the panel frame 1.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
