However, regardless of whether it is beam type or chassis type, the position of the display panel is fixed and the installation method is relatively simple. Utility Model Content

[0004] The purpose of this application is to provide a security gate that can at least solve the problems of the current security gate's display panel setting method being relatively simple, as well as the inconvenience of disassembly, assembly, and transportation.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a security gate, including a first door body, a second door body, and a top connecting assembly. The first door body and the second door body are detachably connected via the top connecting assembly, forming a security screening channel between the first door body and the second door body.

[0007] The top connecting assembly includes a first crossbeam, a second crossbeam, and a chassis. In the extension direction of the security check channel, the first crossbeam and the second crossbeam are detachably disposed on opposite sides of the chassis.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0022] The security gate provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0023] like Figures 1 to 6 As shown in the figure, this application discloses a security gate. Optionally, the security gate can be a millimeter-wave security gate, which has the characteristics of fast scanning imaging speed, comprehensive detection, safety and reliability, good privacy protection effect and high detection accuracy. Of course, it can also be other types of security gates. This application does not make specific limitations on this.

[0024] The security gate includes a first gate body 100, a second gate body 200, and a top connecting assembly 300. The first gate body 100 and the second gate body 200 are detachably connected via the top connecting assembly 300, forming a security screening channel. This security screening channel has an entrance end and an exit end. Personnel enter the security screening channel from the entrance end for security checks and then exit from the exit end. Optionally, both the first gate body 100 and the second gate body 200 may be equipped with millimeter-wave antenna arrays, or both may be equipped with electromagnetic coils, to perform security checks on personnel passing through the security screening channel. That is, the security gate mentioned in this embodiment can be a millimeter-wave security gate, a metal detector, or a human body security screening device such as a mobile phone gate; no specific limitation is made.

[0025] The top connecting assembly 300 includes a first crossbeam 310, a second crossbeam 320, and a chassis 330. In the extension direction of the security check channel, the first crossbeam 310 and the second crossbeam 320 are detachably disposed on opposite sides of the chassis 330. One of the first crossbeam 310 and the second crossbeam 320 is provided with a display panel. The positions of the first crossbeam 310 and the second crossbeam 320 can be interchanged.

[0026] In this embodiment, the top connecting component 300 is modularly designed to form a first crossbeam 310, a second crossbeam 320, and a chassis 330. In the extension direction of the security checkpoint, the first crossbeam 310 and the second crossbeam 320 are detachably mounted on opposite sides of the chassis 330. One of the first crossbeam 310 and the second crossbeam 320 is equipped with a display panel. The positions of the first crossbeam 310 and the second crossbeam 320 can be interchanged, allowing for diverse display panel mounting methods. The display panel can be mounted on either end of the security checkpoint according to actual needs. Therefore, this embodiment solves the problem of the relatively limited display panel mounting methods in current security gates. Furthermore, the modular and detachable design of the top connecting component solves the problem of inconvenient disassembly, assembly, and transportation of existing security gates, helping to improve the convenience and efficiency of disassembly, assembly, and transportation.

[0027] Furthermore, since one of the first door body 100 and the second door body 200 of the same security gate is equipped with a transmitting antenna (or transmitting coil) and the other is equipped with a receiving antenna (or receiving coil), interference will occur if the transmitting antennas (or transmitting coils) of adjacent security gates are close together or the receiving antennas (or receiving coils) of adjacent security gates are close together in a side-by-side arrangement. Therefore, it is usually necessary to arrange the first door bodies 100 of adjacent security gates opposite each other or arrange the second door bodies 200 of adjacent security gates opposite each other. After adopting the above embodiment, the setting positions of the first crossbeam 310 and the second crossbeam 320 of any security gate can be interchanged to meet the actual use requirements.

[0028] In an optional embodiment, the top connecting assembly 300 further includes cables. One of the first crossbeam 310 and the second crossbeam 320 is provided with an adapter plate 311 and a functional device 312, the functional device 312 including a display panel. The functional device 312 is electrically connected to the adapter plate 311. Optionally, the functional device 312 can be electrically connected to the adapter plate 311 via wires to transmit electrical signals. The adapter plate 311 is electrically connected to the motherboard 331 inside the chassis 330 via cables to transmit electrical signals. This solution separates the functional device 312 and the motherboard 331 to reduce the thickness of the chassis 330. At this time, the first crossbeam 310, the second crossbeam 320, and the chassis 330 can be packaged together with the door panel, which facilitates transportation and avoids package loss. At the same time, the functional device 312 is electrically connected to the adapter plate 311, and then the adapter plate 311 is electrically connected to the motherboard 331 via cables, which simplifies the wiring between the functional device 312 and the motherboard 331. Therefore, this solution facilitates the wiring between the functional device 312 and the motherboard 331, and also allows the top connecting component 300 to be packaged together with the first door 100 and the second door 200 for easy transportation.

[0029] Optionally, the first crossbeam 310 is provided with an adapter plate 311 and a functional device 312. Optionally, the functional device 312 also includes a speaker, an infrared detector, etc., which are not specifically limited in this embodiment. The first crossbeam 310 is located at the entrance of the security check channel, and the second crossbeam 320 is located at the exit of the security check channel. The first crossbeam 310 includes a first housing 313, the aforementioned adapter plate 311 and functional device 312. The first housing 313 is provided with a first clearance opening 313a. The adapter plate 311 and the functional device 312 are both disposed in the first receiving cavity of the first housing 313. The first end of the cable is electrically connected to the adapter plate 311, and the second end of the cable extends through the first clearance opening 313a to the outside of the first receiving cavity and is electrically connected to the motherboard 331 in the chassis 330. Since the functional device 312 includes a display panel, when the first crossbeam 310 at the entrance of the security checkpoint is equipped with a display panel, it is convenient for people about to enter the security checkpoint to view the information on the display panel, or for the infrared detector to conduct a preliminary detection of the people passing through.

[0030] In a further optional embodiment, the first housing 313 includes a detachably connected first housing 313b and a first cover plate 313c. The first cover plate 313c and the first housing 313b form a first receiving cavity. The detachable connection between the first cover plate 313c and the first housing 313b facilitates the installation of the adapter plate 311 and the functional device 312. The first cover plate 313c is provided with a first clearance opening 313a. Since the chassis 330 is located between the first crossbeam 310 and the second crossbeam 320, the first clearance opening 313a and part of the assembly gap between the first cover plate 313c and the first housing 313b can be covered by the chassis 330. This helps to improve the sealing of the first receiving cavity and enhances the aesthetics of the security gate.

[0031] Optionally, the first crossbeam 310 further includes a first protective component 314 disposed on the first cover plate 313c. The first protective component 314 is located inside the first receiving cavity and has a clearance through hole 314a opposite to the first clearance opening 313a. The second end of the cable passes through the clearance through hole 314a and the first clearance opening 313a in sequence and extends outside the first receiving cavity. The first protective component 314 is sealed to the cable to prevent water stains, dust and other impurities from the external environment from entering the first receiving cavity, so that the first crossbeam 310 meets the IP66 waterproof and dustproof requirements, thereby protecting the various functional devices 312 and adapter plate 311 and other structures disposed in the first receiving cavity. Of course, the first protective component 314 may not be provided, and the size of the first clearance opening 313a may be adapted to the cable, thereby reducing the entry of impurities into the first receiving cavity.

[0032] Optionally, the first housing 313 further includes a first annular sealing structure 313d, and the first cover plate 313c is sealed to the first housing 313b through the first annular sealing structure 313d, thereby further improving the sealing performance of the first receiving cavity.

[0033] Optionally, the first protective component 314 can be a sealing structure such as a rubber ring; or, in other optional embodiments, the first crossbeam 310 further includes a first fastener 315, the first protective component 314 includes a first protective plate 314b, a first deformable element 314c and a second deformable element 314d, the first deformable element 314c is disposed on the first cover plate 313c, optionally, the first deformable element 314c is fixed to the first cover plate 313c by means of bonding or the like, at least a portion of the second deformable element 314d is disposed in the receiving groove of the first protective plate 314b, optionally, the second deformable element 314d is fixed to the first protective plate 314b by means of bonding or the like, the first protective plate 314b is detachably connected to the first cover plate 313c by the first fastener 315, and both the first deformable element 314c and the second deformable element 314d can deform so that the first protective component 314 seals with the cable.

[0034] During the assembly of the first crossbeam 310, the first protective plate 314b and the first cover plate 313c are pre-connected using the first fastener 315. Then, the first end of the cable is electrically connected to the adapter plate 311. The second end of the cable is then passed sequentially through the clearance hole 314a and the first clearance opening 313a to extend outside the first receiving cavity. Finally, the first fastener 315 is tightened to deform both the first deformable component 314c and the second deformable component 314d, ensuring a sealed fit with the cable. This design, using this type of first protective component 314, achieves a seal while facilitating the movement of the cable relative to the first cover plate 313c when maintaining the functional components 312 within the first crossbeam 310, thus aiding in assembly and disassembly.

[0035] In an optional embodiment, the first crossbeam 310 is provided with a display panel, and the number of security gates is at least two, including a first security gate and a second security gate arranged side by side. In the extension direction of the security inspection channel, the first crossbeam 310 of the first security gate and the first crossbeam 310 of the second security gate can be located on the same side of the chassis 330 or on different sides of the chassis 330. Specifically, when the passage direction of the security inspection channels of the first security gate and the second security gate is the same, the first crossbeam 310 of the first security gate and the first crossbeam 310 of the second security gate can both be set on the same side of the chassis 330; when the passage direction of the security inspection channels of the first security gate and the second security gate is opposite, the first crossbeam 310 of the first security gate and the first crossbeam 310 of the second security gate can be respectively set on different sides of the chassis 330, so that the first crossbeam 310 of each security gate is always located at the entrance end of the security inspection channel. Therefore, the location of the first crossbeam 310 of each security gate can be set according to actual needs, so as to facilitate the viewing of information by passers-by and staff.

[0036] In one optional embodiment, the chassis 330 includes a second outer shell 332 and the aforementioned motherboard 331. The motherboard 331 is disposed in the second receiving cavity of the second outer shell 332. The second outer shell 332 is provided with a second clearance opening 332a. Optionally, on the extension of the security inspection channel, the second clearance openings 332a are provided on both opposite sides of the second outer shell 332. When the number of security inspection gates is at least two and the security inspection gates are arranged side by side, the cable used to electrically connect the first crossbeam 310 and the chassis 330 can pass through the second clearance opening 332a near the first crossbeam 310. The first end of the cable is electrically connected to the adapter plate 311, and the second end of the cable extends through the second clearance opening 332a into the second receiving cavity and is electrically connected to the main board 331. In the width direction of the security inspection channel, third clearance openings 332d are provided on both opposite sides of the second outer shell 332. The transmitting coil in the first door body 100 and the receiving coil in the second door body 200 are both electrically connected to the main board 331 through the third clearance openings 332d. In this design, the first door body 100, the second door body 200, and the first crossbeam 310 share a single main board 331, which saves on the cost of the security gate and facilitates centralized control; additionally, it saves internal space in the first door body 100 and the second door body 200. Of course, the first door body 100 and the second door body 200 can also have separate main boards for individual control.

[0037] In a further optional embodiment, the second housing 332 includes a detachably connected second housing 332b and a second cover plate 332c. The second cover plate 332c and the second housing 332b form a second receiving cavity. The detachable connection between the second cover plate 332c and the second housing 332b facilitates the installation of the motherboard 331. The side wall of the second housing 332b is provided with a second clearance opening 332a, and the second cover plate 332c faces the security checkpoint. This prevents dust and other impurities above the security gate from entering the second receiving cavity through the assembly gap between the second cover plate 332c and the second housing 332b, thereby protecting the motherboard 331.

[0038] Optionally, the chassis 330 further includes a second protective component 333 disposed in the second housing 332b. The second protective component 333 is located within the second accommodating cavity and is close to the second clearance opening 332a. The second end of the cable passes sequentially through the second clearance opening 332a and the second protective component 333 into the second accommodating cavity. The second protective component 333 and the cable are sealed together to prevent water stains, dust, and other impurities from the external environment from entering the second accommodating cavity, thus enabling the chassis 330 to meet the IP66 waterproof and dustproof requirements, thereby protecting the motherboard 331 and other structures disposed within the second accommodating cavity. Of course, the second protective component 333 may not be provided, and the size of the second clearance opening 332a may be adapted to the cable, thereby reducing the entry of impurities into the second accommodating cavity.

[0039] Optionally, the second protective component 333 can be a sealing structure such as a rubber ring; or, in other optional embodiments, the chassis 330 further includes a second fastener 334, and the second protective component 333 includes a second protective plate 333a, a third deformable component 333b, and a fourth deformable component 333c. The second protective plate 333a includes a first mounting portion 333a1, a bearing portion 333a2, and a second mounting portion 333a3 connected in sequence. Both the first mounting portion 333a1 and the second mounting portion 333a3 are detachably connected to the second housing 332b through the second fastener 334. Optionally, both the first mounting portion 333a1 and the second mounting portion 333a3 are provided with a first slotted hole 333a4, and the second fastener 334 cooperates with the first slotted hole 333a4. The second protective plate 333a can be detachably connected to the second housing 332b through the first slotted hole 333a4. The support portion 333a2 moves relative to the second fastener 334 and is parallel to the second cover plate 332c. The third deformation member 333b is disposed on the side of the support portion 333a2 away from the second cover plate 332c. Optionally, the third deformation member 333b is fixed to the support portion 333a2 by means of bonding or the like. The fourth deformation member 333c is disposed on the second housing 332b. Optionally, the fourth deformation member 333c is fixed to the top plate of the second housing 332b by means of bonding or the like. The fourth deformation member 333c is opposite to the third deformation member 333b and the two are in contact. The second end of the cable extends into the second receiving cavity through the gap between the third deformation member 333b and the fourth deformation member 333c. Both the third deformation member 333b and the fourth deformation member 333c can deform to make the second protective component 333 and the cable seal together.

[0040] During the assembly of the chassis 330, the second protective plate 333a and the second housing 332b are pre-connected using the second fastener 334. Then, the second end of the cable is sequentially passed through the second clearance opening 332a and the gap between the fourth deformation component 333c and the third deformation component 333b, and electrically connected to the motherboard 331. Next, the second protective plate 333a is moved downwards a certain distance, causing both the third deformation component 333b and the fourth deformation component 333c to deform. The second fastener 334 is then tightened, at which point both the third deformation component 333b and the fourth deformation component 333c are in a sealed fit with the cable. This design, using this type of second protective component 333, achieves a seal while facilitating cable movement relative to the second housing 332b during maintenance of the motherboard 331 inside the chassis 330, thus aiding in disassembly and assembly.

[0041] Optionally, both the first mounting part 333a1 and the second mounting part 333a3 include a first plate segment and a second plate segment connected together. The second plate segment is bent relative to the first plate segment. The first plate segment is opposite to the side wall of the second housing 332b. The first plate segment is provided with the aforementioned first strip hole 333a4. The first plate segment is detachably connected to the side wall of the second housing 332b through a second fastener 334. The second plate segment is opposite to the top plate of the second housing 332b. The second plate segment is threadedly connected to the connecting post 332b1 on the top plate of the second housing 332b through a third fastener. Specifically, the second plate segment is provided with a second strip hole 333a5. One end of the third fastener passes through the second strip hole 333a5 and is threadedly connected to the connecting post 332b1 to improve the connection stability of the second protective component 333.

[0042] In another optional embodiment, the chassis 330 further includes a sealing ring 335 disposed at the third clearance opening 332d. Optionally, the sealing ring 335 can be a silicone ring. The first door 100 and the second door 200 are both sealed to the second outer shell 332 through the sealing ring 335, thereby improving the sealing performance of the second receiving cavity and preventing water stains, dust and other impurities in the external environment from entering the second receiving cavity.

[0043] Optionally, the second cover plate 332c and the second housing 332b can be detachably connected by fasteners such as screws; or, in other optional embodiments, the chassis 330 further includes a lock 336 disposed on the second cover plate 332c. In the extension direction of the security check channel, one end of the second cover plate 332c is hinged to the second housing 332b, and the other end of the second cover plate 332c is locked to the second housing 332b by the lock 336. In this solution, the second cover plate 332c and the second housing 332b are connected in the above manner. When the chassis 330 is disassembled for maintenance, the second cover plate 332c and the second housing 332b remain connected, which facilitates the second cover plate 332c closing onto the second housing 332b.

[0044] Optionally, the chassis 330 also includes a hinge dust cover 338 and a second annular sealing structure 339. The hinge dust cover 338 is used to protect the hinge for hinged to the second cover plate 332c and the second housing 332b. The second cover plate 332c is sealed to the second housing 332b through the second annular sealing structure 339, which can further improve the sealing performance of the second receiving cavity.

[0045] Optionally, the chassis 330 also includes a USB connector 341 and a dust plug 342. The USB connector 341 is disposed in the second receiving cavity. The second cover plate 332c has an opening 332c1 opposite to the USB connector 341. The dust plug 342 can be used to block the opening 332c1 to seal the second receiving cavity.

[0046] Optionally, the first crossbeam 310 and the chassis 330, as well as the second crossbeam 320 and the chassis 330, can be connected by hooking. Alternatively, in another optional embodiment, the top connecting assembly 300 further includes a first connector 350. The first crossbeam 310 and the second crossbeam 320 are each provided with a first connecting portion 316, and the two opposite side walls of the chassis 330 are each provided with a second connecting portion 337. The second connecting portion 337 and the first connecting portion 316 are stacked, and the two are detachably connected by the first connector 350. With this connection method, not only is the connection stability between the first crossbeam 310 and the second crossbeam 320 and the chassis 330 better, but it is also convenient for disassembly and assembly.

[0047] Optionally, one of the first connecting part 316 and the second connecting part 337 is provided with a positioning post 316a and a threaded connection hole 316b, and the other is provided with a positioning hole 337a and a second through hole 337b. The positioning post 316a is positioned and engaged with the positioning hole 337a, and one end of the first connecting member 350 passes through the second through hole 337b and is threadedly connected to the threaded connection hole 316b. This not only improves the connection stability between the first crossbeam 310 and the second crossbeam 320 and the chassis 330, but also allows the positioning post 316a to act as a guide during the assembly of the top connecting assembly 300, thereby improving assembly efficiency.

[0048] Optionally, the first crossbeam 310 and the first door body 100, as well as the second crossbeam 320 and the second door body 200, can be connected by hooking. Alternatively, in another optional embodiment, the security gate further includes a second connector 400. Both the first door body 100 and the second door body 200 are provided with a first through hole 110. One end of the second connector 400 passes through the first through hole 110 and is threadedly connected to the first crossbeam 310 or the second crossbeam 320, so that the first crossbeam 310 is detachably connected to the first door body 100, and the second crossbeam 320 is detachably connected to the second door body 200. The top connecting component 300 in this solution adopts the above-described connection method, which facilitates the assembly and disassembly of the first door body 100 and the second door body 200 from the top connecting component 300, respectively.
