Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of linkage doors, in particular to a bulletproof and anti-tailgating linkage door. Background Art
[0002] The so-called interlocking door means that two doors have the function of interlocking, that is, when one door is opened, the other door will not be opened. Only when both doors are closed can either door be opened. According to the bank's safety management regulations, two doors must be set up at the entrance and exit of cash counters such as savings outlets, and employees must lock the first door in accordance with regulations after entering the first door before entering the second door. If the first door is not closed as required after entering, the employee will not be able to enter the second door. The purpose of this is to prevent others from following and committing crimes.
[0003] Although the existing linkage doors have certain safety protection performance, there is still insufficient observation when employees enter and exit, so that outsiders may hide in the blind spots of the employees' vision and the employees cannot observe them. There may be a risk of outsiders hiding and following in when the employees open and close the doors. Utility Model Content

[0005] To achieve the above purpose, the following scheme is provided: a bulletproof and anti-tailgating linkage door, comprising a main door body and a protective door, the main door body is installed on the wall, the protective door is installed on the main door body, the protective door comprises a revolving door and a driving mechanism, the revolving door is installed on the driving mechanism, the driving mechanism is fixedly installed on the main door body, an opening is opened at the main door body, the opening is adapted to the revolving door, the driving mechanism comprises a supporting plate, a fixing plate and a driving motor, the fixing plate and the supporting plate are both fixedly installed on the main door body, the supporting plate and the fixing plate are respectively located at the lower end and the upper end of the opening of the main door body, the revolving door is installed between the fixing plate and the supporting plate, a rotating shaft is provided at the bottom of the revolving door, the rotating shaft is rotatably mounted on the supporting plate, the driving motor is fixedly installed on the top of the fixing plate, the driving motor is connected to the top of the revolving door through a reducer, the output end of the reducer is coaxially arranged with the rotating shaft, and the revolving door has a cylindrical structure.
[0006] Furthermore, an observation window is provided at the revolving door, and bulletproof glass is installed at the observation window.
[0007] Furthermore, the main door body and the revolving door are both made of bulletproof steel plates.
[0008] Furthermore, a door lock is installed at the main door body, and the door lock is located at the side of the revolving door. Lock holes adapted to the door lock are installed on both sides of the revolving door.
[0009] The working principle and advantages of the utility model are as follows: the bulletproof and anti-tailgating linkage door enables the user to pass through the main door body from the protection door by adding a protection door to the main door body of the linkage door. The revolving door of the protection door can only accommodate one person, and then can only transfer one person to the other side of the main door body in sequence. At the same time, the user can observe the surrounding situation through the observation window during the rotation of the revolving door, effectively reducing the risk of being followed by outsiders, and timely observing the uncertain factors in the surrounding environment and issuing timely warnings.

[0015] The following is a further detailed description through specific implementation methods:
[0016] like Figures 1 to 3 As shown:
[0017] A bulletproof and anti-tailgating linkage door, comprising a main door body 1 and a protective door, wherein the main door body 1 is installed on a wall, and the main door body 1 is the main structural door body of the linkage door, and the protective door is installed on the main door body 1, and the protective door is used for employees to enter and exit; the protective door comprises a revolving door 4 and a driving mechanism, and the driving mechanism is installed on the inner side of the main door body 1, and is used to install the revolving door 4, so that the revolving door 4 can rotate on the main door body 1, and the revolving door 4 is used for users to stand; an opening 2 is provided on the main door body 1, and the opening 2 is adapted to the revolving door 4, so that users can enter from the opening 2 on the main door body 1 to the revolving door 4; the driving mechanism comprises a supporting plate 6, a fixing plate 7 and a driving motor 8. The fixed plate and the support plate 6 are both fixedly installed on the main door body 1. The support plate 6 and the fixed plate 7 are respectively located at the lower end and the upper end of the opening 2 of the main door body 1. The revolving door 4 is installed between the fixed plate 7 and the support plate 6. The bottom of the revolving door 4 is rotatably connected to the support plate 6 through a rotating shaft. The top of the revolving door 4 is connected to the output end of the reducer. The reducer is connected to the driving motor 8. The driving motor 8 is fixedly installed on the top of the fixed plate 7. The output end of the reducer is coaxially arranged with the rotating shaft and the revolving door 4, so that the driving motor 8 can drive the revolving door 4 to rotate through the reducer. The revolving door 4 is a cylindrical structure, and it is provided with an entrance allowing users to enter the revolving door 4.
[0018] An observation window 5 is provided at the revolving door 4 , and bulletproof glass is installed at the observation window 5 , so that the user can observe the external environment of the main door body 1 through the observation window 5 .
