[0023] The following will be combined with the drawings of the specification 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.

[0024] Reference Figure 1 - Figure 2, The utility model provides an embodiment: a multifunctional building intercom doorbell, including a doorbell body 1, the upper surface of the doorbell body 1 is fixedly connected to a fixing base 2, the internal rotation of the fixing base 2 is connected to a rotating shaft 3, the outer wall of the rotating shaft 3 is fixedly connected to a gear 4, the outer wall of the rotating shaft 3 is fixedly connected to a light shielding cover 5, the outer wall of the doorbell body 1 is fixedly connected to a rectangular box 6, the inner wall of the rectangular box 6 is fixedly connected to one end of a spring 7, the other end of the spring 7 is fixedly connected to a rack 8, the outer wall of the rack 8 is slidably connected to the inner wall of the rectangular box 6, the outer wall of the rack 8 is meshed with the outer wall of the gear 4, the upper surface of the rack 8 is fixedly connected to a pressing block 9, the outer wall of the rectangular box 6 is provided with a through slot 11, the outer wall of the rack 8 is provided with a card slot 10, the doorbell body The outer wall of the body 1 is fixedly connected to a fixed block 12, and a limiting assembly is arranged inside the fixed block 12, which is used to limit the rack 8; the limiting assembly includes a long sliding column 13, the outer wall of the long sliding column 13 is slidably connected to the inside of the fixed block 12, one end of the long sliding column 13 is fixedly connected to the limiting block 14, and the other end of the long sliding column 13 is fixedly connected to a clamping block 15, the outer wall of the clamping block 15 is slidably connected to the inner wall of the clamping groove 10, the outer wall of the clamping block 15 is slidably connected to the outer wall of the rack 8, the outer wall of the clamping block 15 is slidably connected to the inner wall of the through groove 11, and the outer wall of the long sliding column 13 is slidably connected to a spring 2 16, one end of the spring 2 16 is fixedly connected to the outer wall of the clamping block 15, and the other end of the spring 2 16 is fixedly connected to the outer wall of the fixed block 12;

[0025] Specifically, the pressing block 9 is used to provide a force point. By pressing the pressing block 9, the rack 8 is forced to move downward and slide on the inner wall of the rectangular box 6, which can rotate the gear 4, thereby causing the gear 4 to drive the light shielding cover 5 to rotate through the rotating shaft 3. The rack 8 can be pushed and reset by the spring 17. When the rack 8 is not under force, the spring 17 will rebound and reset to push the rack 8 upward, thereby causing the gear 4 to reverse and drive the light shielding cover 5 to return to its original position through the rotating shaft 3. One end of the spring 2 16 is fixedly connected to the outer wall of the card block 15, and the other end is fixedly connected to the outer wall of the fixed block 12 to prevent the long slide post 13 from rotating during the sliding process inside the fixed block 12. The limit block 14 can limit the long slide post 13 to prevent the long slide post 13 from sliding out of the inside of the fixed block 12. At the same time, the limit block 14 can also be pulled to cause the long slide post 13 to drive the card block 15 to move outward from the outer wall of the rack 8 to slide out of the inner wall of the slot 10 to release the limit on the rack 8.

[0026] Reference Figure 1 , the outer wall of the doorbell body 1 is fixedly connected with a mounting block 17;

[0027] Specifically, the doorbell body 1 can be mounted on a wall via the mounting block 17 .

[0028] Reference Figure 1 、 Figure 3 and Figure 4 , the outer wall of the doorbell body 1 is provided with a through groove 2 18, the interior of the doorbell body 1 is provided with a card slot 2 19, and the interior of the doorbell body 1 is provided with an inner groove 20; one end of a spring 3 21 is fixedly connected to the interior of the doorbell body 1, and the other end of the spring 3 21 is fixedly connected to a limit ring 22, and the outer wall of the limit ring 22 is slidably connected to the inner wall of the inner groove 20; the inner wall of the doorbell body 1 is slidably connected to a mounting tube 23, the outer wall of the mounting tube 23 is fixedly connected to a speaker grille 24, and the outer wall of the mounting tube 23 is fixedly connected to a card block 25; the outer wall of the card block 25 is slidably connected to the inner wall of the through groove 2 18, and the outer wall of the card block 25 is slidably connected to the inner wall of the card slot 2 19; the outer wall of the card block 25 is in contact with the end of the mounting tube 23 away from the limit ring 22;

[0029] Specifically, the speaker grille 24 is used to protect the speaker unit of the doorbell and prevent foreign objects from entering. The installation tube 23 can fix the block 25. The installation tube 23 can fix the speaker grille 24. The card slot 29 can provide a space for the card block 25 to engage, and the through slot 2 18 can provide a space for the card block 25 to pass through.

[0030] When the doorbell is in operation, the pressing block 9 is pressed to cause the rack 8 to move downward and slide on the inner wall of the rectangular box 6 and cause the spring 17 to be forced to contract, thereby causing the gear 4 to drive the rotating shaft 3 to rotate inside the fixing seat 2 and drive the light shielding cover 5 to rotate. In the process of the rack 8 moving downward, the outer wall of the card block 15 will slide on the outer wall of the rack 8. In the process of the outer wall of the card block 15 sliding on the outer wall of the rack 8, the card block 15 will be forced to drive the long sliding column 13 to move outward and slide inside the fixing block 12 and cause the spring 2 16 to be forced to contract. When the outer wall of the card block 15 slides into the inner wall of the card slot 10 opened on the outer wall of the rack 8, the force on the card block 15 is weakened, thereby causing the spring 2 16 in the contracted state to rebound and reset, pushing the card block 15 to completely slide into the inner wall of the card slot 10 to limit the rack 8. At this time, the light shielding cover 5 also rotates to a position perpendicular to the doorbell body 1, which can effectively block the doorbell from light. The doorbell can be effectively shielded from light, thereby reducing the reflection of external light, and can more accurately identify the visitor's face and the surrounding environment. During long-term use, the speaker grille 24 is used to accumulate dust and other debris. When the speaker grille 24 needs to be disassembled and cleaned, it is only necessary to press the speaker grille 24 and then drive the card block 25 to slide out from the inner wall of the card slot 2 19 through the installation tube 23, so that the limit ring 22 is forced to slide on the inner wall of the inner groove 20 and force the spring three 21 to contract. Then, the speaker grille 24 is rotated ninety degrees, and then the speaker grille 24 is moved outward to force the installation tube 23 to slide outward on the inner wall of the doorbell body 1 and force the card block 25 to slide through the inner wall of the through groove 2 18, thereby achieving the effect of quickly disassembling the speaker grille 24 for cleaning, thereby ensuring that the sound can be transmitted smoothly, maintaining a clear and bright sound quality effect, and allowing visitors to hear more clearly when talking.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
