Technical Field
[0001] This utility model relates to the field of smart building technology, specifically to a visual intercom and paging device for smart buildings. Background Technology
[0002] Visual access control systems can not only control entry and exit, but also provide functions such as video calls and remote door opening. Some even integrate smart home control and security alarms.
[0003] Currently, visual access control systems are generally fixed directly to outdoor walls using expansion bolts. However, these electronic devices are prone to damage, and the current fixing method makes subsequent disassembly and repair troublesome. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a visual intercom paging device for smart buildings, which can be quickly installed and limited by threaded connection and limiting frame, so as to solve the problems mentioned in the background art.
[0005] This utility model is achieved through the following technical solution: a visual intercom paging device for smart buildings, including a visual access control unit, a base plate, and a limiting frame. The outer ring of the base plate protrudes to form a flange with an annular structure. One end of the limiting frame is fitted onto the outside of the flange. One end of the visual access control unit is inserted into the opening at the other end of the limiting frame. A connecting post is installed on the side of the visual access control unit facing the base plate. A connecting sleeve is installed on the base plate opposite the connecting post. The other end of the connecting post is inserted into the connecting sleeve and threadedly connected to the connecting sleeve. A rubber frame is installed on one end of the limiting frame. Multiple sliding mechanisms are installed between the limiting frame and the flange.
[0006] As a preferred technical solution, the sliding mechanism includes a slider and a first compression spring. Multiple grooves are provided on the outer side of the flange. The slider is slidably disposed in the groove. The outer end face of the slider is installed on the inner side of the limiting frame. One end of the first compression spring is installed on the slider, and the other end is installed on the inner wall of the groove.
[0007] As a preferred technical solution, the outer side of the flange is provided with multiple grooves near the end face of the limiting frame. Each groove opening is provided with a ball, a part of which extends to the outside and contacts the end face of the limiting frame. A second compression spring is installed on one end of the ball inside the groove, and the other end of the second compression spring is installed on the inner wall of the groove.
[0008] As a preferred technical solution, the end of the rubber frame away from the limiting frame is bent outward to form a covering part.
[0009] As a preferred technical solution, both the slider and the groove have trapezoidal cross-sections.
[0010] As a preferred technical solution, the length and width inside the limiting frame match the length and width of the visual access control and the flange.
[0011] As a preferred technical solution, the base plate is provided with multiple countersunk holes.
[0012] As a preferred technical solution, both the limiting frame and the base plate are made of stainless steel.
[0013] The beneficial effects of this utility model are: the utility model has a simple structure. After the limiting frame is pressed down, the visual access control can be directly threaded into the connecting sleeve through the connecting column. The rebound of the first compression spring can fit the limiting frame on the outside of the visual access control, which can position it and prevent rotation, thus ensuring the stability of the installation. The ball can increase the stability of the limiting frame and reduce the probability of forward and backward movement. The rubber frame can cover the gap between the first compression spring, the limiting frame and the wall. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.
[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a visual intercom and paging device for smart buildings, including a visual access control 1, a base plate 5, and a limiting frame 2. The outer ring of the base plate 5 protrudes to form a ring-shaped flange 8. One end of the limiting frame 2 is fitted onto the outside of the flange 8. One end of the visual access control 1 is inserted into the opening at the other end of the limiting frame 2. A connecting post 11 is installed on the side of the visual access control 1 facing the base plate 5. A connecting sleeve 12 is installed on the base plate 5 opposite to the connecting post 11. The other end of the connecting post 11 is inserted into the connecting sleeve 12 and threadedly connected to the connecting sleeve 12. A rubber frame 3 is installed on one end of the limiting frame 2. Multiple sliding mechanisms are installed between the limiting frame 2 and the flange 8.
[0024] In this embodiment, the sliding mechanism includes a slider and a first compression spring 7. Multiple grooves 6 are provided on the outer side of the flange 8. The slider is slidably disposed in the groove 6. The outer end face of the slider is installed on the inner side of the limiting frame 2. One end of the first compression spring 7 is installed on the slider, and the other end is installed on the inner wall of the groove 6.
[0025] In this embodiment, the outer side of the flange 8 is provided with a plurality of grooves near the end face of the limiting frame 2. Each groove opening is provided with a ball 9, a part of which extends to the outside and contacts the end face of the limiting frame 2. A second compression spring is installed on one end of the ball 9 inside the groove, and the other end of the second compression spring is installed on the inner wall of the groove.
[0026] In this embodiment, the end of the rubber frame 3 away from the limiting frame 2 is bent outward to form a covering part 4. After the base plate is installed, the covering part can fit against the wall, increasing the contact area between the rubber frame and the wall, and can block external dust as much as possible.
[0027] In this embodiment, both the slider and the groove 6 have trapezoidal cross-sections, which allows the slider to move back and forth along the groove, preventing the slider from detaching from the groove.
[0028] In this embodiment, the length and width inside the limiting frame 2 match the length and width of the visual access control 1 and the flange 8.
[0029] In this embodiment, the base plate 5 is provided with multiple countersunk holes 10, and bolts can pass through the countersunk holes to fix the base plate to the wall.
[0030] In this embodiment, both the limiting frame 2 and the base plate 5 are made of stainless steel, which increases the sturdiness and prevents rusting.
[0031] Working principle: The base plate can be fixed to the wall with bolts, and the limiting frame can move towards one end of the wall. Then, the connecting post on the visual access control is aligned with the connecting sleeve and threadedly connected to the connecting sleeve. As the visual access control moves into place, the limiting frame can be released. The limiting frame can push the slider upward by the rebound of the first compression spring. The movement of the slider drives the limiting frame, so that one end of the limiting frame can be fitted onto the outside of the visual access control. The limiting frame can position the visual access control and prevent it from rotating again.
[0032] In this system, after the limiting frame is fitted onto the outside of the visual access control system, the ball pops out through the rebound energy of the second compression spring and abuts against the end face of the limiting frame. The ball can provide a limiting function for the limiting frame, preventing the limiting frame from moving back and forth on its own and increasing the stability after installation.
[0033] The rubber frame can cover the first compression spring and seal the gap between the limiting frame and the wall, increasing the integrity of its surface.
[0034] During disassembly, the limiting frame can be pushed towards the wall again. After the limiting frame is moved away from the outside of the visual access control, the visual access control can rotate until it detaches from the connecting sleeve, which greatly facilitates disassembly.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
