[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1

[0022] A door lock structure for a power distribution cabinet, such as Figure 1-Figure 6As shown, it includes a support plate 1, a mounting shell 2, a fixing plate 3, a support shaft 4, a double-layer gear 5, a guide rod 6, a clamping rod 7, a rack 8, a reset spring 9, a spur gear 10 and a rotating rod 11. The support plate 1 is divided into two parts, the left part is rotatably mounted on the door frame, and the right part is fixedly mounted on the door frame. The left part of the support plate 1 is installed with a mounting shell 2, and the right part of the support plate 1 is installed with a fixing plate 3. The fixing plate 3 is provided with eight clamping holes. A support shaft 4 is provided in the middle of the mounting shell 2. The support shaft 4 is rotatably connected with a double-layer gear 5. The double-layer gear 5 includes two layers of gears. The first layer of the upper layer is a small gear, and the second layer of the lower layer is a large gear. When one layer of the gears in the double-layer gear 5 rotates, the other layer of the gears will also rotate synchronously. The double-layer gear 5 has a high transmission efficiency, can greatly reduce the loss of mechanical energy, improve work efficiency, and also It can reduce energy consumption and achieve the purpose of high efficiency and energy saving. A guide rod 6 is installed above and below the inside of the installation shell 2, and the two guide rods 6 are both sleeved with reset springs 9. The two guide rods 6 are slidably provided with a clamping rod 7. The right end of the reset spring 9 is connected to the clamping rod 7, and the left end is connected to the installation shell 2. There are eight plug rods on the right side of the clamping rod 7. The clamping rod 7 is movably connected to the fixed plate 3 through the eight plug rods, and is movably connected and locked with the fixed plate 3 through the eight plug rods, so that the door lock structure is more stable. A rack 8 is connected to the middle part of the left side of the clamping rod 7, and the rack 8 is meshed with the small gear of the double-layer gear 5. A spur gear 10 is rotatably provided at the lower part of the installation shell 2, and the spur gear 10 is meshed with the large gear of the double-layer gear 5. A rotating rod 11 is provided on the spur gear 10, and handles are symmetrically provided on the rotating rod 11. The handles on both sides are convenient for the staff to rotate the rotating rod 11 to open and close the cabinet door.

[0023] When it is necessary to open the distribution cabinet door lock, the rotating rod 11 is rotated by the handle. The rotating rod 11 rotates to drive the spur gear 10 to rotate. The rotation of the spur gear 10 drives the second gear of the double-layer gear 5 meshing with it to rotate. The second gear of the double-layer gear 5 rotates and the first gear also rotates synchronously. Then the double-layer gear 5 drives the rack 8 meshing with it to move through the rotation of the first gear, thereby driving the clamping rod 7 connected to the rack 8 to move along the guide rods 6 at both ends, so that the several plug rods on the clamping rod 7 are separated from the fixed plate 3. When the several plug rods on the clamping rod 7 are completely separated from the fixed plate 3, the left part of the support plate 1 can be rotated to open the distribution cabinet door. When the cabinet door needs to be closed, the rotating rod 11 is rotated in the same way to make the clamping rod 7 engage with the fixed plate 3.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1As shown, it also includes a leakage detector 12, a warning light 13 and a warning sign 14. The leakage detector 12 is arranged on the lower right side of the installation shell 2. The leakage detector 12 monitors the current in the distribution cabinet through a current transformer. When an abnormal current change is detected, it will trigger an alarm circuit, which can prevent electric shock accidents and ensure the safety of operators and maintenance personnel. A warning light 13 is arranged on the top of the leakage detector 12. When the leakage detector 12 detects a leakage, the warning light 13 can light up to provide an intuitive status indication, so that operators and maintenance personnel can quickly turn the distribution cabinet to see if there is a leakage. A warning sign 14 is installed on the installation shell 2. The warning sign 14 can remind personnel to pay attention to safe operation and warn of dangerous areas.

[0026] When leakage detection of the power distribution cabinet is required, current will flow through the leakage detector 12, triggering an alarm, thereby lighting up the warning light 13, attracting the attention of personnel, and taking timely measures to prevent accidents. The warning sign 14 provides clear warning and guidance information, allowing personnel to operate the power distribution cabinet more carefully and in a standardized manner, while warning irrelevant personnel to stay away from the power distribution cabinet.
