[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: a high-voltage cable chamber interlocking mechanism, including: the lower surface 1 of the cable chamber, and a limiting plate 2 arranged on the upper side of the lower surface 1 of the cable chamber, and a housing 3 is arranged on the upper side of the limiting plate 2. It further includes:

[0029] A first motor 8, which is installed inside the lower surface 1 of the cable chamber, and a limiting disk 9 is connected to the left side of the first motor 8. A limiting groove 10 is opened inside the limiting disk 9, and a locking component 11 is arranged on the upper side of the limiting disk 9. A connecting disk 12 is connected to the left side of the limiting disk 9, and a connecting rod 13 is arranged on the outer side of the connecting disk 12. A third limiting block 14 is connected to the outer side of the connecting rod 13, and a guiding block 15 is arranged on the outer side of the third limiting block 14. A cable chamber door body 16 is arranged on the left side of the housing 3, forming a complete interlocking mechanism.

[0030] As Figure 1 , Figure 2 and Figure 4 shown, the locking component 11 includes a second limiting block 1101 installed on the upper side of the limiting disk 9, and a second guiding rod 1102 is arranged on the outer side of the second limiting block 1101. A reciprocating lead screw 1103 is arranged in the middle of the second guiding rod 1102, and a second motor 1104 is connected to the upper side of the reciprocating lead screw 1103. The second limiting block 1101 is relatively clamped with the limiting disk 9, and the second limiting block 1101 is relatively threaded with the reciprocating lead screw 1103. By driving the reciprocating lead screw 1103 to rotate on the upper side of the housing 3 through the second motor 1104, the reciprocating lead screw 1103 pushes the second limiting block 1101 to displace downward. At this time, the second limiting block 1101 is clamped and fixed with the limiting disk 9, so that the limiting disk 9 cannot rotate when the device is energized, thereby completing the locking of the device and reducing the possibility of electric shock accidents.

[0031] As Figure 1 , Figure 2 and Figure 4As shown, the second limit block 1101 is slidably arranged relative to the second guide rod 1102, and the second guide rod 1102 is symmetrically arranged about the central axis of the second limit block 1101. When the second limit block 1101 is pushed downward by the reciprocating screw rod 1103, the second guide rod 1102 guides the second limit block 1101 at this time, preventing the second limit block 1101 from deviating in angle and position during downward displacement and reducing the locking safety of the device.

[0032] As Figure 1 , Figure 2 and Figure 5 shown, the connecting plate 12 and the connecting rod 13 are relatively meshed, and the connecting rod 13 is relatively threadedly connected to the third limit block 14. The first motor 8 drives the limit plate 9 to rotate inside the housing 3, so that the limit plate 9 drives the connecting plate 12 to rotate. The connecting plate 12 pushes the connecting rod 13 to rotate on the left side of the housing 3, thereby completing the power transmission work, converting the horizontal rotational force into a vertical rotational force, and facilitating the device to lock and open the cable chamber door.

[0033] As Figure 1 , Figure 2 and Figure 5 shown, the third limit block 14 is relatively engaged with the cable chamber door body 16, and a guide block 15 is arranged on the outside of the third limit block 14 and is slidably arranged relative to the housing 3. The connecting rod 13 drives the third limit block 14 to displace inward along the guide block 15, so that the third limit block 14 releases the opening and closing limit of the cable chamber door body 16, facilitating the operator to open the cable chamber door body 16.

[0034] As Figure 1 , Figure 2 and Figure 3 shown, a first limit block 4 is arranged on the right side of the housing 3, a damper 5 is arranged on the right side of the first limit block 4, a first guide rod 6 is arranged on the outside of the damper 5, and a hand-held rod 7 is arranged on the right side of the first guide rod 6. The first limit block 4 is relatively engaged with both the limit plate 2 and the housing 3, and the first guide rod 6 is slidably arranged relative to the housing 3. By pulling the hand-held rod 7 to the right, the hand-held rod 7 drives the first guide rod 6 and the first limit block 4 to displace to the right and squeeze the damper 5. At this time, the housing 3 is installed on the upper side of the limit plate 2, and at the same time, the pulling of the hand-held rod 7 is released, so that the damper 5 pushes the first limit block 4 to rebound and reset along the first guide rod 6. At this time, the first limit block 4 is engaged and limited with the limit plate 2, thereby completing the convenient installation and disassembly work of the housing 3, reducing the labor intensity of the operator, and reducing the maintenance cost of the device.
