Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] This utility model embodiment provides a dustproof and waterproof elevator control box, such as... Figures 1-5 As shown, the device includes a base 1 and a lid 2, which are mounted together to form a mounting cavity. The base 1 has an inner cavity and an opening 11 communicating with the inner cavity. Each of the four sides of the lid 2 has a horizontally extending flange 31. The ends of two adjacent flanges 31 are connected, thus forming a sealing flange 3 that surrounds the opening 11. After the base 1 and lid 2 are connected, the sealing flange 3 abuts against the inner side wall of the lid 2, and the lid 2 covers the opening 11. The side wall of base 3 has a larger area than the original base 1, thus better sealing the gap between the lid 2 and the opening 11, resulting in a larger sealing area. For further sealing, a sealing gasket 4 is correspondingly provided on the sealing flange 3. The sealing gasket 4 surrounds the outer periphery of the opening 11, and is pressed between the sealing flange 3 and the inner side wall of the lid 2, forming a sealing section for better sealing. Furthermore, the area of ​​the sealing gasket 4 is larger than that of the sealing flange 3, maximizing the sealing section and improving sealing performance, as well as dust and water resistance. It should be noted that the sealing gasket 4 is a commercially available sealing gasket.

[0032] Specifically, in existing elevator control boxes, the base box and car wall are fixed together, making them difficult to disassemble during maintenance. In this embodiment, a snap-fit ​​post 9 is provided on the base 1, and a snap-fit ​​groove 7 is provided on the inner side wall of the cover 2. The snap-fit ​​post 9 and the snap-fit ​​groove 7 are used to connect the base 1 and the cover 2 together, thereby facilitating the disassembly of the base 1 and the cover 2. Moreover, after the two are connected, the sealing protrusion 3 on the inner side wall of the cover 2 and the base 1 presses the sealing gasket 4 against the middle to seal the installation cavity.

[0033] In another embodiment, each convex edge 31 is provided with a sealing protrusion along its length, which can partially compress the sealing gasket 4 into an arc shape, thereby improving the sealing performance between the sealing convex edge 3 and the lid 2. It should be noted that the sealing protrusion can be at one end, in multiple segments, or a through groove. Furthermore, it should be noted that the inner wall of the lid 2 can also be provided with corresponding sealing protrusions to cooperate and abut against the sealing gasket 4.

[0034] Furthermore, sealing flanges 51 are vertically formed on all four sides of the lid 2. The four sealing flanges 51 are connected to form a sealing edge 5. When the inner side wall of the lid 2 is connected to the sealing flange 3, the sealing edge 5 surrounds the outer side of the sealing flange 3, so that the sealing gasket 4 can be surrounded inside. The sealing edge 5 serves as the first line of defense against dust and water to a certain extent. At the same time, the sealing edge 5 can also increase the strength of the lid 2.

[0035] Specifically, in order to connect the lid 2 and the base 1, in this embodiment, as follows: Figure 3 As shown, the inner wall of the lid 2 is provided with two parallel mounting plates 6, which are arranged along the length of the lid 2. Multiple slots 7 are provided at the ends of the mounting plates 6 away from the inner wall of the lid 2. These slots 7 are inclined and have the same inclination. The diameter of each slot 7 gradually decreases from the opening 11 to the bottom. Correspondingly, the two side walls of the base 1 along its length are provided with mounting walls 12, each corresponding to one mounting plate 6. Multiple snap-fit ​​posts 9 are provided on each mounting wall 12. When the lid 2 is connected to the base 1, the two mounting plates 6 are located at... Between the mounting walls 12, the snap-fit ​​pins 9 on adjacent mounting walls 12 are engaged with the snap-fit ​​slots 7 on the mounting plate 6. That is, the snap-fit ​​pins 9 on the left mounting wall 12 are engaged with the snap-fit ​​slots 7 on the left mounting plate 6, and the snap-fit ​​pins 9 on the right mounting wall 12 are engaged with the snap-fit ​​slots 7 on the right mounting plate 6. Specifically, because the snap-fit ​​slots 7 are inclined, when connecting the base 1 and the cover 2, the cover 2 needs to be moved along its length and inclined towards the base 1, so that the snap-fit ​​pins 9 move relative to the opening 11 of the snap-fit ​​slot 7 to the bottom of the snap-fit ​​slot 7, thus connecting the base 1 and the cover 2. Of course, when disassembling, the cover 2 needs to be moved in the opposite direction.

[0036] Specifically, the snap-fit ​​post 9 can be configured as a stud, which is threaded onto or embedded in the mounting wall 12 to form the snap-fit ​​post 9. Furthermore, an elastic sleeve is provided on the outer wall of the snap-fit ​​post 9, so that after the snap-fit ​​post 9 is located at the bottom of the slot 7, the elastic sleeve can be compressed, which can reduce frictional damage between the slot 7 and the snap-fit ​​post 9, and increase the installation stability of the snap-fit ​​post 9 at the bottom of the slot 7.

[0037] Specifically, the elevator control box also houses multiple elevator components, such as elevator button assemblies, elevator display screen assemblies, intercom assemblies, etc. These elevator components are correspondingly installed on the cover 2, which has multiple mounting holes 21. The main body of the elevator components is located inside the mounting cavity, while the operating ends of the elevator components (such as the display screen of the elevator display screen assembly, the buttons in the floor button assembly, etc.) are located on the multiple mounting holes 21 for easy operation by the user. The edges of the main body of the elevator components are sealed to the inner wall of the cover 2. Specifically, the gap between the edge of the main body of the elevator components and the inner wall of the cover 2 is sealed with waterproof glass adhesive, achieving dust and water protection at the mounting holes 21 on the cover 2. Of course, other areas, such as the side wall of the base 1, are provided with waist-shaped mounting holes 21. The entire elevator control box is installed on the external mounting plate 6 through these mounting holes 21. After installation, the remaining parts of the waist-shaped mounting holes 21 are sealed with waterproof glass adhesive.

[0038] Specifically, such as Figure 5 As shown, a reinforcing edge 8 is provided on the outer wall of the protruding edge 31. The reinforcing edge 8 extends away from the cover 2 and is perpendicular to the protruding edge 31, so that the protruding edge 31 and the reinforcing edge 8 form an L-shaped structure, which can further increase the contact strength of the protruding edge 31 and ensure its service life.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
