Therefore, the above terms should not be construed as limitations on this application.

[0021] Example 1: This embodiment provides an elevator power lock, such as Figure 1 , Figure 2 , Figure 3 As shown, the lock includes a lock cylinder 1 and a lock housing 2. The lock cylinder 1 is mounted on the lock housing 2. The lock housing 2 has a top cover 3 on one side and a bottom cover 4 on the other side. An outer cavity 5 is formed between the top cover 3 and the lock housing 2, and an inner cavity 6 is formed between the bottom cover 4 and the lock housing 2. A first sealing element 7 is provided between the lock cylinder 1 and the lock housing 2 to waterproof the inner cavity 6 and the outer cavity 5. A micro switch 8 is provided on the inner cavity 6, and the trigger part of the micro switch 8 is in contact with the rotating part of the lock cylinder 1. The bottom cover 4 is connected to the lock housing 2, and the top cover 3 is connected to the lock housing 2. The top cover 3 is annular, and the center of the annulus is used to expose the key hole of the lock cylinder 1.

[0022] The lock cylinder 1 cooperates with the key 18; the lock shell 2 provides installation space for components and provides protection; the design of the outer cavity 5 and the inner cavity 6 facilitates the installation of different components on both sides, reducing mutual interference between the two sides; the design of the first seal 7 isolates the outer cavity 5 and the inner cavity 6 from each other, which can improve the waterproof performance of the inner cavity 6 and prevent rainwater in the outer cavity 5 from entering the inner cavity 6, so that the elevator power lock has a certain waterproof capability and is suitable for outdoor use; the micro switch 8 cooperates with the lock cylinder 1, so that the rotation of the lock cylinder 1 is converted into an electrical signal by triggering the micro switch 8.

[0023] To facilitate drainage of the outer cavity 5, a drainage hole 9 is provided between the top cover 3 and the lock shell 2. The drainage hole 9 connects the outer cavity 5 to the outside; the drainage hole 9 is located at the lowest point of the outer cavity 5. The design of the drainage hole 9 allows water entering the outer cavity 5 to be discharged to the outside through the drainage hole 9, preventing water accumulation in the outer cavity 5, and thus preventing water from entering the inner cavity 6, improving waterproof performance; the drainage hole 9 is located at the lowest point, which facilitates the drainage of all accumulated water in the outer cavity 5.

[0024] In this embodiment, the drain hole 9 is located on the lock shell 2. Specifically, the lock shell 2 has a second notch, and the drain hole 9 is formed between the second notch and the top cover 3. Of course, the top cover 3 may also have a second notch, and the drain hole 9 is formed between the second notch and the lock shell 2, or both the lock shell 2 and the top cover 3 may have a second notch, and the two second notches may cooperate to form the drain hole 9.

[0025] To facilitate drainage, a gap 10 is provided between the lock housing 2 and the lock cylinder 1 located in the outer cavity 5; the gap 10 is connected to the drainage hole 9. The design of the gap 10 allows rainwater entering the outer cavity 5 to flow downwards through the gap 10, preventing it from accumulating in a certain place inside. The connection between the gap 10 and the drainage hole 9 allows the downward-flowing rainwater to reach the bottom of the outer cavity 5 and be directly discharged through the drainage hole 9, preventing water accumulation inside.

[0026] To improve waterproofing, two first sealing elements 7 are spaced apart at the front and rear; the first sealing elements 7 are sealing rings. The two first sealing elements 7 provide a double seal, enhancing waterproofing. Specifically, the lock cylinder 1 has a second groove 19, and the first sealing element 7 is located on the second groove 19, simplifying the positioning and installation of the first sealing element 7.

[0027] To ensure reliable separation between the outer cavity 5 and the inner cavity 6, the lock housing 2 includes a partition 11. The outer cavity 5 and the inner cavity 6 are separated by the partition 11, meaning that the outer cavity 5 is formed between the top cover 3 and the partition 11, and the inner cavity 6 is formed between the bottom cover 4 and the partition 11. The partition 11 has a through hole 12, through which the lock cylinder 1 passes. The partition 11 separates the outer cavity 5 and the inner cavity 6, improving the protective performance between them. The through hole 12 allows the lock cylinder 1 to pass through, facilitating the triggering of the micro switch 8 in the inner cavity 6.

[0028] To ensure waterproof performance, the partition 11 is provided with a protruding ring 13, and the lock cylinder 1 passes through the protruding ring 13. The first sealing element 7 is located between the protruding ring 13 and the lock cylinder 1. The design of the protruding ring 13 can guide the installation of the lock cylinder 1 and at the same time provide a contact surface with the first sealing element 7, which facilitates the installation of the first sealing element 7.

[0029] Specifically, the diameter of the through hole 12 is the same as the inner diameter of the convex ring 13, and the through hole 12 and the convex ring 13 are concentric; the convex ring 13 extends toward the inner cavity 6.

[0030] To ensure the waterproof performance of the inner cavity 6, a second sealing element 14 is provided between the lock housing 2 and the bottom cover 4. The second sealing element 14 is used to improve the waterproof performance between the lock housing 2 and the bottom cover 4 and prevent liquid from entering the inner cavity 6 from between the lock housing 2 and the bottom cover 4.

[0031] To ensure reliable installation of the lock housing 2 and the bottom cover 4, the bottom of the lock housing 2 is provided with a first groove 15, and the bottom cover 4 is provided with a boss 16 that mates with the first groove 15; the first groove 15 is arranged in a ring around the bottom edge of the lock housing 2. The first groove 15 and the boss 16 mate to facilitate precise positioning and installation between the bottom cover 4 and the lock housing 2, while also enhancing the protective performance at the connection between the bottom cover 4 and the lock housing 2. In this embodiment, the boss 16 is arranged in a ring around the edge of the bottom cover 4.

[0032] To ensure reliable installation of the second seal 14, the second seal 14 is located on the first groove 15, which facilitates the positioning and installation of the second seal 14; the second seal 14 is a sealing ring.

[0033] To ensure the reliable operation of the elevator power lock, the bottom cover 4 is provided with a first notch 17. The first notch 17 is used for the micro switch 8 to connect with the outside. The external cable can enter the inner cavity 6 through the first notch 17 and connect with the micro switch 8, so that the trigger signal of the micro switch 8 can be transmitted to the outside through the cable.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
