Description

Technical Field

[0001] The utility model relates to the technical field of installation equipment, in particular to a door access control indoor display screen mechanism installation device. Background Art

[0002] The structure of the home video access control system includes two sets of mechanisms, outdoor and indoor. In actual application, the owner of the home can communicate with people outside the door through audio and video without opening the door. For strangers, the door can be allowed to enter without opening the door, which can achieve good security effects.

[0003] The outdoor mechanism of the visual access control system is generally installed on the anti-theft door, while the indoor mechanism is generally installed on the indoor wall. In the prior art, there are generally two ways to install the indoor mechanism of the visual access control system. The first is to directly install the indoor mechanism (the main structure is the liquid crystal display screen and the voice playback and transmission equipment located in the shell, which is collectively referred to as the access control indoor display screen mechanism. In specific use, the user watches the facial information of the outdoor personnel transmitted by the camera of the outdoor mechanism through the display screen indoors, and tries to communicate with the outdoor personnel through the voice equipment) on the wall through multiple expansion bolts. Since the equipment is exposed to the outside, this method increases the probability of being damaged by collision with other foreign objects (for example, the user does housework, or moves objects and collides with the equipment); in addition, when the fixed installation of the access control indoor display screen mechanism has problems and needs to be disassembled for repair, the process of disassembling and installing expansion bolts is relatively cumbersome and will bring inconvenience to the user. The second installation method is to install the access control indoor display screen mechanism in a mounting shell on the wall. Although this method reduces the probability of the access control indoor display screen mechanism being hit by other foreign objects, it is still fixed in the shell by multiple bolts or screws. In particular, the operating range in the shell is limited, so the subsequent disassembly and assembly will still cause inconvenience to the user. Finally, due to various reasons, when gas leaks in the home, the existing access control indoor display screen mechanism does not have a gas detection prompt function. In this way, the user does not receive a prompt before opening the door from the outside to enter the home, and there is a chance of gas poisoning or accidentally causing an explosion (for example, if you enter the house without knowing and press the power switch of the light, the power switch contacts will close and generate sparks to ignite the leaked gas). Taking the above factors into consideration, it is very necessary to provide a device that is easy to install an access control indoor display screen mechanism, can be easily disassembled, and can monitor in real time whether there is a gas leak in the home.

[0018] Figure 1 , 2As shown in Figure 3, the inner diameter of the housing 1 is larger than the outer diameter of the access control indoor display screen mechanism 8, and the outer diameter of the movable frame 2 is smaller than the inner diameter of the housing 1. The guide grooves 103 on both sides of the lower end of the housing and the limit grooves 104 on both sides of the upper end of the housing are respectively in a vertical plane, and the lengths of the guide grooves 103 and the limit grooves 104 are consistent. An adjustment handle 31 with an outer diameter larger than the outer diameter of the guide groove is welded to the upper end of the positioning screw 3, and the rear end of the front magnet 6 and the front end of the rear magnet 5 have opposite polarities. There is an opening at the joint between the component box 7 and the housing 1, and the power plug connected to the access control indoor display screen mechanism 8 is inserted into the jack of the power socket connected to the 220V AC power supply (the power plug and the power socket are located in the component box, and the guide has a length margin); the front end of the access control indoor display screen mechanism 8 is located on the front inner side of the housing 1. The detection mechanism includes a combustible gas detection module A2 and an annunciator B connected by circuit board wiring, and the power output terminals 3 and 2 of the combustible gas detection module A2 and the power input terminals of the annunciator B are respectively connected by wires.
