[0001] This utility model relates to the field of security gate technology, specifically a rotary security gate. Background Technology

[0002] With social development and the continuous improvement of security awareness, security gates, as an important security detection device, are widely used in various public places, such as airports, train stations, subway stations, government agencies, and large event venues. Security gates mainly use metal detection technology and electromagnetic induction principles to detect whether the person being inspected is carrying metal objects, so as to ensure public safety and prevent dangerous items from entering the protected area.

[0003] Chinese utility model patent with announcement number CN207513477U discloses a rotating security gate. This device has a security detection device installed in the entrance channel and a sliding door installed on the gate to close the exit and prevent people carrying dangerous goods from passing through the exit. Compared with ordinary rotating gates, it integrates the function of security detection.

[0004] Existing security gates and the aforementioned technologies have revealed some limitations. For example, current security gates are all open and do not have a closed barrier to isolate the security area from the external environment. This makes it easy for security gates to generate false alarms in complex environments, such as when there are a large number of metal decorations, electronic devices or other metal objects, which affects the accuracy and efficiency of detection. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes the following technical solution:

[0006] A rotating security gate includes a base, on which a housing is fixedly mounted. A top shell is fixedly mounted at the end of the housing away from the base. The base, housing, and top shell form a security inspection chamber. The main body of the security inspection chamber is cylindrical. A main shaft is fixedly mounted inside the base. A separator is fixedly mounted on the outer wall of the main shaft. The separator is located inside the security inspection chamber and consists of multiple detection chambers. The separator contacts the inner wall of the security inspection chamber. The multiple detection chambers on the separator are used to place the person being inspected in a sealed environment. An inner turntable is rotatably mounted on the base and fixed to the bottom of the separator. The inner turntable is used for the person being inspected to stand on.

[0007] Furthermore, a bottom support column is fixedly installed at the bottom of the base, a main motor is fixedly installed on the bottom support column, a motor gear is fixedly installed on the output shaft of the main motor, a sliding ring is slidably installed inside the base, and two foot pedals are fixedly installed on the outer wall of the sliding ring. Stepping on the foot pedals will cause the sliding ring to move together.

[0008] Furthermore, a gear ring is rotatably mounted on the sliding ring, and multiple tooth blocks are fixedly mounted on the outer wall of the gear ring. An arc-shaped rack is provided on the tooth block, and the arc-shaped rack on the tooth block meshes with the motor gear on the main motor. A notched toothed disc is rotatably mounted inside the base, and the notched toothed disc is fixedly connected to the inner turntable.

[0009] Furthermore, the notched gear disk can mesh with the motor gear on the main motor. The notched gear disk is provided with multiple gear notches. The gear notches mesh with the gear blocks. When the gear blocks and the notched gear disk are meshed, the notched gear disk and the notched gear disk form a complete gear disk.

[0010] The advantages of this utility model compared with the prior art are: (1) This device sets multiple detection chambers on the separator, allowing the person being tested to be tested along with the detection chambers in the same building, thus avoiding environmental interference with the detection process and improving detection accuracy; (2) This device further improves the safety of the device by allowing the notched toothed disc and the toothed block to disengage from each other.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1 to 4 As shown, a rotating security gate includes a base 101, on which a housing 102 is fixedly mounted. A top housing 105 is fixedly mounted at the end of the housing 102 away from the base 101. The base 101, housing 102, and top housing 105 form a security inspection chamber. The main body of the security inspection chamber is cylindrical. A detection module 107 is disposed inside the housing 102 to generate a magnetic field for detection. Figure 2 As shown, the detection module 107 is disposed on the inner wall of the outer casing 102 on the side with the longer arc.

[0021] like Figures 1 to 4 As shown, an entrance step 103 and an exit step 104 are provided on the outer wall of the base 101. The angle between the entrance step 103 and the exit step 104 is 120 degrees. A main shaft 106 is fixedly installed inside the base 101 and is fixedly connected to the top shell 105. A separator 201 is fixedly installed on the outer wall of the main shaft 106. The separator 201 is located in the security inspection chamber and consists of multiple detection chambers. Radio frequency transmitting modules and receiving coils are evenly arranged in the multiple detection chambers of the separator 201 to transmit low-frequency electromagnetic waves and monitor changes in the electromagnetic field. The separator 201 is in contact with the inner wall of the security inspection chamber. The multiple detection chambers on the separator 201 are used to keep the person being inspected in a sealed environment, thereby improving the accuracy of security inspection.

[0022] like Figures 4 to 6As shown, an inner turntable 202 is rotatably mounted on the base 101. The inner turntable 202 is fixed to the bottom of the separator 201. The inner turntable 202 is used for the person being tested to stand on. A bottom support column 204 is fixedly mounted on the bottom of the base 101. A plurality of steel columns 203 are provided at one end of the bottom support column 204 near the inner turntable 202. The steel columns 203 are in contact with the inner turntable 202 and are used to reduce the friction between the inner turntable 202 and the bottom support column 204.

[0023] like Figures 4 to 6 As shown, a main motor 206 is fixedly installed on the bottom support 204, and a motor gear is fixedly installed on the output shaft of the main motor 206. A sliding ring 208 is slidably installed inside the base 101. Two foot pedals 207 are fixedly installed on the outer wall of the sliding ring 208. The two foot pedals 207 are distributed and correspondingly installed on the entrance step 103 and the exit step 104. A main spring 209 is fixedly installed on the foot pedal 207. The main spring 209 is correspondingly fixedly installed on the entrance step 103 and the exit step 104 to allow the foot pedal 207 to return to its initial state. When the person being tested passes through the entrance step 103 or the exit step 104, the person being tested will step on the foot pedal 207, thereby causing the foot pedal 207 to move together with the sliding ring 208.

[0024] like Figures 4 to 7 As shown, a gear ring 211 is rotatably mounted on the sliding ring 208. Multiple tooth blocks 210 are fixedly mounted on the outer wall of the gear ring 211. The number of tooth blocks 210 is the same as the number of detection chambers on the separator 201. Each tooth block 210 has an arc-shaped rack, which can mesh with the motor gear on the main motor 206. A notched gear disc 212 is rotatably mounted inside the base 101. The notched gear disc 212 is fixedly connected to the inner turntable 202 and can mesh with the main motor 206. The motor gear on the motor 206 meshes with the notched gear disk 212, which has multiple gear notches. These gear notches can engage with the gear block 210. When the gear block 210 and the notched gear disk 212 are fully engaged, and the gear ring 211 is in complete contact with the opposite side of the notched gear disk 212, the gear block 210 will fill the multiple gear notches on the notched gear disk 212. In this state, the notched gear disk 212 becomes a complete gear disk. The engagement state between the notched gear disk 212 and the gear block 210 is the normal state of this device.

[0025] When this device is in operation, the person being tested must ensure they do not possess any metal objects before entering. The person then enters the device through entrance step 103. While standing on entrance step 103, the inner rotating disc 202 and separator 201 within the device are rotating normally in the direction of rotation. Figure 2The device rotates clockwise. After the person being tested stands on the foot pedal 207 on the entrance step 103, their weight will cause the foot pedal 207 and the sliding ring 208 to move away from the inner turntable 202. This allows the sliding ring 208 to move along with the gear ring 211 and the gear block 210, thereby disengaging the gear block 210 from the notched gear disk 212. In this state, the gear block 210 will no longer mesh with the motor gear on the main motor 206. If, during the process of being driven by the motor gear, the notched gear disk 212 rotates to the gear notch, the notched gear disk 212 will... When the geared disc 212 disengages from the motor gear, the inner turntable 202 and the separator 201 stop rotating. When the inner turntable 202 and the separator 201 are not rotating, a detection chamber on the separator 201 aligns with the entrance step 103, facilitating entry of the person being tested into the outer casing 102. During the testing process, the detection module 107 on the inner wall of the outer casing 102, along with the radio frequency transmitting module and receiving coil within the detection chamber, begin operating, detecting the person being tested through electromagnetic induction. The person being tested, upon entering the detection chamber, moves along with the inner turntable 202... Figure 2 The device rotates clockwise, allowing the person being tested to stand still within the testing chamber. The chamber also creates a closed space to improve testing accuracy. When the chamber reaches the exit step 104, the person can step onto the foot pedal 207. This foot pedal 207, along with the sliding ring 208 and toothed block 210, moves, stopping the rotation of the separator 201 and the inner turntable 202. This prevents the separator 201 from trapping the person during rotation, avoiding risks during use. The device allows for continuous testing of individuals.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
