Description

Technical Field

[0001] The utility model relates to the technical field of safety doors, in particular to an anti-tailgating linkage interlocking safety door. Background Art

[0002] In places with high security requirements, people entering and leaving will be detected through security gates. Only authorized individuals can enter restricted areas. If someone stalks, an alarm will be triggered and the security door will be locked.

[0003] The safety door usually has two doors. After the personnel enter the compartment, the first door will be closed and then the second door will be opened. There is no effective protection measure inside the compartment. Once the personnel follow into the compartment and trigger the alarm to lock the safety door, the following person and the staff are inside the compartment at the same time, and the staff in the compartment are in danger of life. For this reason, we propose an anti-tailgating linkage interlocking safety door to solve the existing problem. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, the utility model proposes an anti-tailgating linkage interlocking safety door, including a car body 1, a car roof 2, a tank body 5, a mounting column 9 and a motor 10, an opening and closing door 3 is arranged at both the front and rear ends of the car body 1, a car roof 2 is arranged at the upper end of the car body 1, a rotating car 15 is arranged inside the car body 1, a mounting column 9 is rotatably installed at the center position of the rotating car 15, a rotating door 18 distributed in a ring array is arranged on the outer wall of the mounting column 9, an inlet 16 and an outlet 19 are respectively opened at the front and rear ends of the rotating car 15, a sensor 17 is arranged on the inner wall of the upper end of the car body 1, a motor 10 is arranged inside the upper end of the car roof 2, a driving gear 11 is arranged at the output end of the lower end of the motor 10, a driven gear 12 is sleeved on the outer wall of one end of the mounting column 9 located inside the car roof 2, the driving gear 11 and the driven gear 12 are meshed with each other, a hydraulic rod 13 is arranged inside one side of the car roof 2, a chuck 14 is arranged at the telescopic end of the hydraulic rod 13, and the chuck 14 is sleeved on the outer side of the driven gear 12.

[0021] Based on the implementation steps of Example 1: the staff opens one of the opening and closing doors 3 to enter the interior of the compartment 1, then closes the opened opening and closing door 3, then opens another opening and closing door 3 from the interior of the compartment 1, and closes the opening and closing door 3 opened later when walking out of the compartment 1. When walking inside the compartment 1, it is necessary to pass through the revolving door 18. The staff enters the revolving door 18 through the entrance 16, and the motor 10 drives the driving gear 11 to rotate, and the driving gear 11 drives the driven gear 12 to rotate, thereby driving the mounting column 9 to rotate, so that the revolving door rotates;

[0022] The staff walks between the two revolving doors to intercept the trailing personnel from behind. Even if the trailing personnel enters the compartment 1, they are in the revolving door 18 behind the staff and separated from the staff by the revolving door 18. The staff in front can continue to walk in the rotating revolving door 18. When the opening and closing door 3 at the other end is opened, the staff opens the safety door and walks out of the compartment 1. The hydraulic rod 13 drives the chuck 14 to jam the driven gear 12, and the revolving door 18 is then locked, trapping the trailing personnel in the revolving door 18 to prevent the trailing personnel from entering the restricted area.

[0023] like Figure 1-Figure 4As shown, the anti-tailgating linkage interlocking safety door proposed by the utility model is compared with the first embodiment, and this embodiment also includes: symmetrically distributed mounting pipes 20 are arranged inside the upper end of the compartment 1, a tank body 5 is arranged on the inner wall of the lower end of the compartment roof 2, a delivery pump 6 is arranged at one end of the tank body 5, a delivery pipe 7 is arranged at the output end of the delivery pump 6, the delivery pipe 7 passes through the mounting pipe 20, and nozzles 21 equidistantly distributed are arranged at the lower end of the mounting pipe 20, a control valve 8 is arranged at the output end of the delivery pump 6, the extraction end of the delivery pump 6 passes through the tank body 5, and sound and light alarms 4 are arranged on the outer walls of the opening and closing doors 3.

[0024] In this embodiment, after the staff leaves the compartment 1, the delivery pump 6 extracts the protective gas inside the tank 5. The protective gas is selected according to needs to play a role in making the following personnel drowsy and dizzy. According to needs, when the following personnel are highly aggressive, the protective gas is delivered to the inside of the installation pipe 20, output through the nozzle 21, and acts on the inside of the rotating compartment 15, so that after the following personnel inhale the protective gas, they lose the ability to resist, thereby playing a good protective role.
