[0025] Embodiment 1: Please refer to Figure 1-6 , the present invention provides the following technical solution: A maintenance box for an elevator pit with a waterproof function, including a maintenance box main body 1. A connecting line 101 is provided on the outer wall of the maintenance box main body 1. A waterproof mechanism is provided on the outer wall of the maintenance box. The waterproof mechanism includes a protective shell 2 fixedly installed on the outer wall of the maintenance box. A protective cover 3 is slidably installed on the outer wall of the protective shell 2. And an observation window 301 is provided on the outer wall of the protective cover 3. A sealing groove 201 is opened on the outer wall of the protective shell 2. And a sealing gasket 4 is provided in the sealing groove 201. And a clamping block 302 fixedly installed with the protective cover 3 is slidably connected to the outer wall of the sealing gasket 4. A threaded block 5 is fixedly installed on the outer wall of the protective shell 2. And a sealing plug 501 is slidably installed in the inner wall of the threaded block 5. And an extrusion block 502 is provided at the end of the sealing plug 501. A sealing cover 503 is threadedly installed on the outer wall of the threaded block 5. The protective shell 2 completely wraps the maintenance box. And a through hole for the connecting line 101 to pass through is opened on the outer wall of the protective shell 2. The observation window 301 is made of a transparent material. The sealing groove 201 is opened on the outer wall of the side where the protective shell 2 and the protective cover 3 are in contact. And the cross-section of the sealing groove 201 is designed in a "return" shape. The cross-section of the sealing gasket 4 is designed in an inverted "L" shape. And the outer wall of the sealing gasket 4 is in contact with the inner wall of the sealing groove 201. The clamping block 302 is arranged corresponding to the sealing gasket 4. And the outer wall of the clamping block 302 is in contact with the outer wall of the sealing gasket 4. The threaded block 5 is arranged corresponding to the connecting line 101. The cross-section of the sealing plug 501 is designed in a circular ring shape. And the outer diameter of the sealing plug 50 is corresponding to the inner diameter of the threaded block 5. And the inner wall of the sealing plug 501 is in close contact with the outer wall of the connecting line 101. The cross-section of the extrusion block 502 is designed in a T shape. And one end of the extrusion block 502 is in contact with the outer wall of the sealing plug 501. And the other end of the extrusion block 502 is in contact with the inner wall of the sealing cover 503. The sealing cover 503 is arranged corresponding to the threaded block 5.

[0026] It should be noted that there may be some inaccuracies in the translation of the specific shape description in this text. For example, "几" in Chinese is translated as "L" here, which may need to be adjusted according to the actual situation. You can further check and correct it according to the specific context.The protective shell 2 is firmly fixed to the outer wall of the inspection box, completely enclosing it and preventing external moisture from directly contacting the main body 1 of the inspection box. When the protective cover 3 slides to close with the protective shell 2, the locking block 302 fixedly installed on the protective cover 3 slides into the sealing gasket 4. The outer wall of the locking block 302 fits tightly against the outer wall of the sealing gasket 4. This tight fit greatly increases the resistance to moisture entry, effectively preventing moisture from entering from the joint between the protective shell 2 and the protective cover 3. At the point where the connecting wire 101 passes through the protective shell 2, the protective shell 2... A threaded block 5 corresponding to the connecting wire 101 is fixedly installed on the outer wall. When the sealing cover 503 is tightened, the sealing cover 503 will apply pressure to the sealing plug 501 through the extrusion block 502, so that the sealing plug 501 will further tightly wrap the connecting wire 101, thereby effectively sealing the inlet of the connecting wire 101 and preventing moisture from entering the inside of the maintenance box from the inlet. The protective cover 3 is provided with a transparent observation window 301, which allows the staff to observe the inside of the maintenance box without opening the protective cover 3 and to understand the working status of the maintenance box in a timely manner.

[0027] Example 2: Based on Example 1, a limiting mechanism is also disclosed, the specific structure of which is as follows: The outer wall of the protective shell 2 is provided with a limiting mechanism for fixing the protective cover 3. The limiting mechanism includes a fastening bolt 6 rotatably installed on the outer wall of the protective shell 2, and a fixing block 601 is threadedly installed at the end of the fastening bolt 6. A protrusion 7 is fixedly installed on the outer wall of the protective cover 3, and a through groove 702 and a limiting groove 701 are opened on the outer wall of the protrusion 7. The fastening bolt 6 is symmetrically arranged on both sides of the outer wall of the protective shell 2, and the outer wall of the fastening bolt 6 is threaded. The fixing block 601 has a T-shaped cross section, and the outer wall of the fixing block 601 is threaded with a corresponding threaded hole to the fastening bolt 6. The protrusion 7 is symmetrically arranged on both sides of the outer wall of the protective cover 3. The through groove 702 is correspondingly arranged with the fastening bolt 6. The limiting groove 701 is correspondingly arranged with the bottom end of the fixing block 601, and the inner wall of the limiting groove 701 is in contact with the outer wall of the end of the fixing block 601.

[0028] The limiting mechanism securely fixes the protective cover 3, ensuring waterproofing while facilitating operation. When the protective cover 3 needs to be closed, it is first slid along the outer wall of the protective shell 2 to the closed position. At this time, the fastening bolt 6 on the protective shell 2 will pass through the through groove 702 on the protrusion 7. Then, the fixing block 601 is threaded onto the end of the fastening bolt 6 through the threaded hole on its outer wall corresponding to the fastening bolt 6. Since the fixing block 601 has a T-shaped cross-section, as the fixing block 601 is screwed into the fastening bolt 6, the bottom of the fixing block 601... The end will gradually enter the limiting groove 701 on the protrusion 7 until the inner wall of the limiting groove 701 is tightly fitted with the outer wall of the end of the fixing block 601. In this way, the fastening bolt 6 and the fixing block 601 will firmly fix the protective cover 3 to the protective shell 2, ensuring a tight connection between the protective cover 3 and the protective shell 2, thereby ensuring the waterproof effect of the waterproof mechanism. When it is necessary to open the protective cover 3, simply rotate the fixing block 601 in the opposite direction to make it exit from the limiting groove 701, and then slide the protective cover 3 along the outer wall of the protective shell 2 to open it. The operation is very convenient.
