[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] This utility model provides a technical solution, please refer to Figure 1-4 :

[0025] An outdoor waterproof power distribution cabinet includes a cabinet body 1 and a heat dissipation hole 2. A fixing rod 4 is fixed to the cabinet body 1 and extends through a circular hole 6 formed in a cover plate 3. The cover plate 3 fits the cabinet body 1 and blocks the heat dissipation hole 2, allowing heat emitted from the heat dissipation hole 2 to be normally dissipated into the environment through the cover plate 3. A protrusion 7 is fixed to the cabinet body 1, and a rotating rod 8 is rotatably connected to the protrusion 7. A pressure plate 10 is fixed to the rotating rod 8 and abuts the cover plate 3. A torsion spring 9 is provided between the rotating rod 8 and the protrusion 7. The cover plate 3 is provided with a limiter to limit the pressure plate 10. A sealing ring is provided on the portion of the cover plate 3 that contacts the cabinet body 1, thereby preventing rainwater from passing through the cover plate 3 and reaching the heat dissipation hole 2 on the cabinet body 1. Under the elastic force of the torsion spring 9, the pressure plate 10 can be rotated, causing it to press the cover plate 3 into contact with the cabinet body 1.

[0026] Example 2:

[0027] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the limiting member includes a side block 11 fixed to the pressure plate 10, and a sleeve hole 12 is formed in the side block 11. When the pressure plate 10 rotates, the sleeve hole 12 is sleeved on the fixing rod 4 until the pressure plate 10 abuts the cover plate 3. A positioning block 13 extends into the sleeve hole 12, and the positioning block 13 has a through hole 14 that is slidably connected to the fixing rod 4. The fixing rod 4 is provided with a fixing member that fixes the position of the pressure plate 10. The positioning block 13 has a notch 15, which can be used to push the positioning block 13 to move, thereby causing the positioning block 13 to disengage from the sleeve hole 12 and the fixing rod 4.

[0028] Example 3:

[0029] The technical solution is basically the same as that of embodiment 1, except that Figure 2 and Figure 4As shown, the fixing member includes a screw groove 5 formed on the fixing rod 4, which is threadedly connected to a screw block 17 fixed to a round block 16, and the round block 16 abuts the pressure plate 10 and the positioning block 13. The portion where the round block 16 abuts the pressure plate 10 and the positioning block 13 is provided with an elastic rubber gasket, so that the round block 16 does not wear when abutting against the pressure plate 10 or the positioning block 13.

[0030] In summary, when the cover plate 3 provided in this embodiment is installed with the cabinet 1:

[0031] Apply force to the pressure plate 10 to rotate it upward until the fixing rod 4 is exposed. Then, the circular hole 6 on the cover plate 3 can be put on the fixing rod 4 on the cabinet body 1, and the force on the pressure plate 10 can be released. Under the elastic force of the torsion spring 9, the pressure plate 10 rotates to press the cover plate 3 into contact with the cabinet body 1. The sleeve hole 12 is put on the fixing rod 4, and the positioning block 13 is inserted into the sleeve hole 12, and the through hole 14 on the positioning block 13 is put on the fixing rod 4 until the positioning block 13 contacts the cabinet body 1. At this time, the pressure plate 10 can stably exert pressure on the cover plate 3, and the pressure plate 10 cannot be forced to rotate away from the cover plate 3, so the cover plate 3 and the cabinet body 1 are now connected as one.

[0032] If necessary, the screw block 17 on the round block 16 can be connected to the screw groove 5 on the fixing rod 4 through a threaded connection, and the round block 16 can abut against the positioning block 13 and the side block 11. At this time, under the action of the round block 16, the pressure plate 10 can press the cover plate 3 more stably, and the positioning block 13 cannot separate from the side block 11.
