Abstract
Description
Technical Field

[0002] The long and complex information transmission links of electromechanical equipment in subway stations lead to low communication efficiency and poor mobile network signals for passengers. Although installing wireless switches in subway station passages can improve the poor mobile network signal by providing short-link network signals, the wireless switches are usually installed on the walls of the subway station passages by installing a grooved support plate on the wall and then installing the wireless switch into the groove of the support plate. The wireless switch lacks an effective protective structure at the top during installation, and dust and hard particles falling from the subway will fall onto the wireless switch. In order to prevent dust and hard particles from affecting the normal use of the wireless switch, it is generally necessary to regularly inspect and clean the surface of the wireless switch and remove other hard particles.

[0025] See Figure 1 , Figure 2 and Figure 3 A subway station communication device includes a wireless switch 1, which is installed inside a protective shell 2. The front end of the protective shell 2 has a through hole 20, and the top of the protective shell 2 has a cover plate 3. A limiting mechanism 4 is connected inside the protective shell 2 and is connected to the cover plate 3. The limiting mechanism 4 is used to prevent the cover plate 3 from detaching from the protective shell 2 when it is opened from the top. The rear end of the protective shell 2 is connected to a mounting block 5, which is connected to the passage wall 100 of the subway station by expansion bolts 6. The bottom end of the protective shell 2 is mounted on a support mechanism 7, which is connected to the passage wall 100 of the subway station.
[0026] See Figure 4 and Figure 5 The limiting mechanism 4 includes a fixing component 41, a rotating block 42, a connecting block 43, a connecting rod 44, and an elastic component 45. The fixing component 41 and the connecting block 43 are connected to the first enclosure 21 of the protective shell 2. The rotating block 42 is connected to the fixing component 41. The connecting block 43 is connected to the first end of the connecting rod 44. The second end of the connecting rod 44 is connected to the elastic component 45. The elastic component 45 is connected to the second enclosure 22 of the protective shell 2 adjacent to the first enclosure 21. A sliding block 8 is connected to the cover plate 3, and the sliding block 8 can slide on the rotating block 42.
[0027] The rotating block 42 is rotatably connected to the fixed component 41, and the rotating block 42 is capable of rotating on the fixed component 41. A groove is provided on the first enclosure 21, and the sliding block 8 is disposed in the groove, with the length of the sliding block 8 being the same as the length of the first enclosure 21.
[0028] See Figure 4 and Figure 5 The fixing component 41 includes a fixing block 411 and a fixing shaft 412 connected to the fixing block 411. The first enclosure 21 is provided with an opening 210. The fixing block 411 is connected to the opening 210. The rotating block 42 is connected to the fixing shaft 412. The rotating block 42 can rotate on the fixing shaft 412 and can be pressed into the opening 210.
[0029] The top end of the fixed block 411 is connected to the fixed shaft 412, and the rotating block 42 is rotatably connected to the fixed shaft 412, so that the rotating block 42 can rotate relative to the fixed block 411. When the rotating block 42 rotates toward the inside of the protective shell 2, the rotating block 42 can press against the top surface of the fixed block 411 in the opening 210.
[0030] See Figure 4 and Figure 5 The connecting block 43 includes a first connecting portion 431 and a second connecting portion 432 that are perpendicularly connected to each other. The first connecting portion 431 is connected to the first enclosure plate 21, and the second connecting portion 432 is provided with a connecting hole for connecting the connecting rod 44. The connecting block 43 and the connecting rod 44 are fixedly connected; when the connecting rod 44 is connected to the connecting hole on the connecting block 43, the connecting rod 44 does not rotate within the connecting hole.
[0031] See Figure 4 and Figure 5 The connecting rod 44 includes a first connecting rod 441 and a second connecting rod 442. The end of the first connecting rod 441 is connected to a first connecting post 443, and the end of the second connecting rod 442 is connected to a connecting end 444. The connecting end 444 is connected to a through hole for connecting to the elastic component 45. The connecting end 444 is also connected to a second connecting post 445.
[0032] The first connecting post 443 is connected to the connecting hole 4320 of the second connecting part 432. The first connecting post 443 and the connecting hole are interference fit, and the first connecting post 443 does not rotate within the connecting hole.
[0033] See Figure 4 and Figure 5The elastic component 45 includes a connecting plate 451, which is connected to the second enclosure 22, and a third connecting post 452 is connected to the upper end of the connecting plate 451.
[0034] The lower end of the connecting plate 451 is connected to a fourth connecting post 454, a second fixing block 455 is connected to the fourth connecting post 454, a spring 456 is connected to the second fixing block 455, and the other end of the spring 456 is connected to a first fixing block 453, which is connected to the connecting rod 44.
[0035] The third connecting post 452 is connected to the through hole of the connecting end 444, and the connecting end 444 of the connecting rod 44 is rotatable on the third connecting post 452. The second connecting post 445 is connected to the first fixing block 453, and the second connecting post 445 and the first fixing block 453 are fixedly connected. The second fixing block 455 is rotatable on the fourth connecting post 454.
[0036] Among them, see Figure 4 and Figure 5 The principle between the limiting mechanism 4 and the cover plate 3 is as follows:
[0037] The top of the cover plate 3 is provided with an operating handle 31. When the cover plate 3 is moved from the side of the protective shell 2 to the top of the protective shell 2 by operating the operating handle 31, the cover plate 3 causes the rotating block 42 to rotate inward towards the inside of the protective shell. At the same time, the sliding block 8 moves with the cover plate 3. During the movement of the cover plate 3, the sliding block 8 can move on the rotating block 42. When the cover plate 3 moves, the connecting rod 44 is stressed, and the connecting end 444 of the connecting rod 44 rotates clockwise on the third connecting post 452. The first fixing block 453 at the top of the spring 456 moves with the connecting end 444. After the spring 456 is stressed, the second fixing block 455 at the lower end of the spring 456 is a movable end that can rotate on the fourth connecting post 454. When the cover plate 3 can completely cover the top of the protective shell 2, the connecting rod 44 rotates from the left side of the connecting plate 451 to the right side of the connecting plate 451, and the rotating block 42 rotates from a vertical position to press on the fixing block 411 in the opening 210. When the cover plate 3 completely covers the protective shell 2, the cover plate 3 can be stably fixed on the protective shell 2 due to its own weight, the connecting rod 44 and the spring 456.
[0038] When the cover plate 3 is moved away from the top of the protective shell 2 by operating the operating handle 31, and the cover plate 3 gradually moves closer to the side of the protective shell 2, the connecting rod 44 moves with the cover plate 3. The connecting end 444 of the connecting rod 44 rotates counterclockwise on the third connecting post 452. The connecting rod 44 rotates from the right side of the connecting plate 451 to the left side of the connecting plate 451. The rotating block 42 gradually moves away from the fixed block 411. When the cover plate 3 is completely moved to the side of the protective shell 2, the cover plate 3 will not fall off the protective shell 2 because the other end of the connecting rod 44 is restricted by the spring 6.
[0039] Compared to using a key and lock to secure the cover plate 3, the aforementioned limiting mechanism 4 simplifies the operation process, making it easier to inspect and replace the wireless switch 1 in the protective casing 2.
[0040] See Figure 4 and Figure 5 The support mechanism 7 includes a first connecting plate 71, on which a plurality of extension plates 72 are connected at intervals. The portion of the connecting plate 71 at the gap between the extension plates 72 is connected to the passage wall of the subway station by the expansion bolts 6. The protective shell 2 is disposed on the extension plate 72. The lower end of the extension plate 72 is connected to a support plate 73, which is connected to a second connecting plate 74. The second connecting plate 74 is connected to the passage wall of the subway station by the expansion bolts 6.
[0041] In summary, the provided subway station communication device provides a protective shell for the wireless switch 1, which protects the wireless switch 1 when it is installed in the subway station passage. At the same time, a related support mechanism 7 is provided to support the protective shell on the wall of the subway station passage. The protective shell is provided with an easy-to-operate cover plate to facilitate the installation, maintenance and replacement of the wireless switch 1 inside the protective shell.
