[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a detachable modular unit door intercom device includes a base plate 1, a fixing mechanism 2 rotatably connected to the inner side of the base plate 1, a protective shell 3 fixedly connected to the outer side of the fixing mechanism 2 near the front side, an intercom mechanism 4 movably sleeved on the inner side of the protective shell 3, a rubber ring 5 fixedly connected to the front side of the base plate 1 near the edge, and the outer side of the protective shell 3 movably sleeved on the inner side of the rubber ring 5 near the rear side.

[0027] The fixing mechanism 2 includes a rotating shaft 21. The rear side of the rotating shaft 21 is rotatably connected to the inner rear surface of the substrate 1 near the four corners. There are four rectangular rotating shafts 21. Two vertically distributed locking blocks 22 are fixedly connected to the outer side of the rotating shaft 21 near the front side. Four rectangularly distributed mechanism tubes 23 are fixedly connected to the inner side of the protective shell 3 near the four corners. Two annularly distributed spiral grooves 24 are opened on the inner side of each of the four mechanism tubes 23. The outer sides of the rotating shaft 21 and the locking blocks 22 are movably sleeved on the inner side of the spiral grooves 24.

[0028] It should be noted that a torsion spring is provided between the rotating shaft 21 and the base plate 1 to stabilize the state of the rotating shaft 21. The mechanism tube 23 is used to set the spiral groove 24. Due to the setting of the locking block 22, the inner rear edge of the mechanism tube 23 coincides with the outer edge of the front surface of the rotating shaft 21, so that the rotating shaft 21 and the locking block 22 are directly inserted into the mechanism tube 23 and the spiral groove 24. Due to the shape of the spiral groove 24, the spiral groove 24 drives the rotating shaft 21 to rotate by the locking block 22. When the rotating shaft 21 is fully inserted into the mechanism tube 23, the locking block 22 disengages from the spiral groove 24, so that the torsion spring drives the rotating shaft 21 to reset, thereby fixing the protective shell 3 with the rotating shaft 21 and the locking block 22.

[0029] like Figure 3 As shown, a first gear 25 is rotatably connected to the middle of the inner rear surface of the substrate 1. A second gear 26 is movably sleeved on the outer side of each of the four rotating shafts 21 near the rear side. A third gear 27 is meshed between each of the four second gears 26 and the first gear 25. A fourth gear 28 is meshed to the right side of the first gear 25. A fifth gear 29 is meshed to the right side of the fourth gear 28. A lock cylinder 210 is movably installed at the front axis of the fifth gear 29.

[0030] It should be noted that when a key is inserted into the lock cylinder 210, the lock cylinder 210 drives the fifth gear 29 to rotate. When the fifth gear 29 rotates, it drives the fourth gear 28 to rotate. When the fourth gear 28 rotates, it drives the first gear 25 to rotate. When the first gear 25 rotates, it drives the third gear 27 to rotate. When the third gear 27 rotates, it drives the second gear 26 to rotate. When the second gear 26 rotates, it drives the rotating shaft 21 to rotate, so that the rotating shaft 21 can be disengaged from the mechanism tube 23, causing the protective shell 3 and the intercom mechanism 4 to be removed from the base plate 1.

[0031] like Figure 4 As shown, each of the four second gears 26 has two centrally symmetrical movable slots 211 in the middle of its front side, and the outer side of the rotating shaft 21 near the rear side of the protrusion is movably sleeved on the inner side of the movable slot 211.

[0032] It should be noted that the setting of the movable groove 211 means that when the rotating shaft 21 and the locking block 22 rotate in the mechanism tube 23, the rotating shaft 21 will not drive the rotating shaft 21 to rotate. However, when the rotating shaft 21 is in the initial state, the second gear 26 can drive the rotating shaft 21 to rotate.

[0033] like Figure 5 As shown, the intercom mechanism 4 includes a base plate 41. A display module 42 is attached to the front side of the base plate 41. A voice module 43 is attached to the front side of the base plate 41 near the upper right side. A camera module 44 is attached to the front side of the base plate 41 near the lower right side. A T-shaped plate 45 is fixedly connected to the front side of the base plate 41 near the right side. The T-shaped plate 45 is located between the display module 42, the voice module 43, and the camera module 44. The outer sides of the base plate 41, the display module 42, the voice module 43, and the camera module 44 are movably fitted inside the protective shell 3.

[0034] It should be noted that the base plate 41 is equipped with a cooling system, a control system, and a battery lamp component. The base plate 41 is electrically connected to the display module 42, the voice module 43, and the camera module 44 in the form of a plug and socket. While supplying power and transmitting data to the base plate 41, the display module 42, and the voice module 43, it also serves to fix the display module 42, the voice module 43, and the camera module 44 on the base plate 41. The outer side of the base plate 41 is provided with a rubber layer so that the base plate 41 moves with the protective shell 3 when it is removed from the base plate 1.

[0035] like Figure 5 As shown, three cutouts 46 are provided on the front side of the T-shaped plate 45 near the three ends, and the protrusion on the inner side of the front wall of the protective shell 3 near the right side is movably fitted inside the cutouts 46.

[0036] It should be noted that the notch 46 is designed to fix the T-shaped plate 45 to the inner protrusion of the front wall of the protective shell 3, and at the same time facilitates the filling of the notch 46, thus avoiding the problem of increased gap between the front wall of the T-shaped plate 45 and the inner wall of the front wall of the protective shell 3 due to friction caused by the horizontal insertion of the T-shaped plate 45 into the inner wall of the front wall of the protective shell 3.

[0037] like Figure 5 As shown, a copper sheet is fixedly connected to the front side of the base plate 41.

[0038] It should be noted that the copper sheet is used to conduct the heat generated by the display module 42, the voice module 43 and the camera module 44, so that the cooling system inside the base plate 41 can dissipate heat quickly.

[0039] like Figure 5 As shown, two filter screens 47 are movably fitted on the upper and lower sides of the base plate 41.

[0040] It should be noted that a magnetic sheet is provided between the filter screen 47 and the base plate 41 for fixing. At the same time, the upper sides of the base plate 41 have insertion holes on the right side of the filter screen 47, which makes it easy to pry the filter screen 47 out from the inner side of the upper and lower walls of the base plate 41.

[0041] The working principle of this utility model is as follows: First, a torsion spring is provided between the rotating shaft 21 and the base plate 1 to stabilize the state of the rotating shaft 21. The mechanism tube 23 is used to set the spiral groove 24. Due to the setting of the locking block 22, the inner rear edge of the mechanism tube 23 coincides with the outer edge of the front surface of the rotating shaft 21, allowing the rotating shaft 21 and the locking block 22 to be directly inserted into the mechanism tube 23 and the spiral groove 24. Due to the shape of the spiral groove 24, the spiral groove 24 drives the rotating shaft 21 to rotate by the locking block 22. When the rotating shaft 21 is fully inserted into the mechanism tube 23, the locking block 22 disengages from the spiral groove 24, causing the torsion spring to drive the rotating shaft 21 to reset, thus fixing the rotating shaft 21 and the locking block 22 to the protective shell 3. A key is inserted into the lock cylinder 210, causing the lock cylinder 210 to drive the fifth gear 29 to rotate. The rotation of the fifth gear 29 drives the fourth gear 28 to rotate, which in turn drives the first gear 25 to rotate. The rotation of the first gear 25 drives the third gear 27 to rotate, which in turn drives the second gear 26 to rotate. The rotation of the second gear 26 drives the rotating shaft 21 to rotate, allowing the rotating shaft 21 to detach from the mechanism tube 23. This allows the protective housing 3 and the intercom mechanism 4 to be removed from the base plate 1 and directly inserted into the mechanism tube 23 via the rotating shaft 21. This quickly secures the protective housing 3 and the intercom mechanism 4 to the base plate 1, while simultaneously enclosing the rotating shaft 21 and the locking block 22 within the mechanism tube 23. To prevent external personnel from accessing the device, a key is inserted into the lock cylinder 210 during disassembly, allowing the protective shell 3 and intercom mechanism 4 to be quickly removed from the base plate 1. This facilitates easy installation and disassembly while preventing unauthorized personnel from disassembling it. Finally, the base plate 41 houses a cooling system, a control system, and battery components. Electrical connections between the base plate 41 and the display module 42, the voice module 43, and the camera module 44 are provided via plugs and sockets. These connections supply power and transmit data to the base plate 41, display module 42, and voice module 43, while simultaneously securing the display module 42, voice module 43, and camera module 44 to the base plate 41. A rubber layer is provided on the side, so that when the protective shell 3 is removed from the base plate 1, the base plate 41 moves with the protective shell 3. The cut 46 is provided so that the protrusion on the inner side of the front wall of the protective shell 3 fixes the T-shaped plate 45. At the same time, it is convenient to fill the cut 46, avoiding the problem of increased gap between the front wall of the T-shaped plate 45 and the inner side of the front wall of the protective shell 3 due to friction caused by the horizontal insertion of the T-shaped plate 45 into the inner side of the front wall of the protective shell 3. Through the electrical connection of the plug and socket, the functional modules of the device are divided into four parts: base plate 41, display module 42, voice module 43 and camera module 44. The modular design allows for quick replacement if one of them is damaged, without affecting use and maintenance.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
