[0002] When going through entry and exit procedures at airports and ports, staff usually take passports for face and fingerprint comparison. Only after the comparison is qualified can entry and exit be processed. This process is busy and requires long queues, and staff work in shifts 24 hours a day. In order to improve efficiency, some entry and exit processing points have adopted self-service login equipment to facilitate personnel to go through entry and exit procedures on their own, so as to reduce queue time and staff working time. Since facial recognition comparison and comparison result display are required, and everyone's height is different, self-service login equipment is usually equipped with a lifting mechanism to adjust the height of the camera and display screen. In order to realize the electrical connection and data transmission of modules such as display screens, a drag chain or accordion chain is usually set between the display screen module and the host. In the existing lifting mechanism, there will be external drag chains or accordion chains, which affects the appearance; and the lifting gap may cause problems such as pinching hands during the lifting process. The drag chain cable is exposed for a long time, and the equipment cable is prone to aging, causing equipment failure. Utility Model Content

[0027] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the lifting mechanism 100 with built-in drag chain includes a column 1, a mobile component 2 and a drag chain 3. The host module 91 is fixedly connected to the bottom of the column 1, the data interaction module 92 is connected to the mobile component 2, and the mobile component 2 is slidably arranged on the column 1 along the axial direction of the column 1, so that the display screen 921, the camera 922, etc. can be lifted and moved. The two ends of the drag chain 3 are respectively connected to the column 1 and the mobile component 2, and the built-in cable is used to realize the electrical connection between the host module 91 and the data interaction module 92, so that the two can perform data transmission.

[0028] like Figure 4 and Figure 5 As shown, the column 1 includes a support column 11, a cover plate 13, and two side baffles 12. The cover plate 13 and the two side baffles 12 are arranged along the extended axial direction of the support column 11.

[0033] like Figure 4 As shown, the drag chain 3 is located between the cover plate 13 and the support column 11. The cover plate 13 can be used to cover the drag chain 3. The lateral sides of the cover plate 13 are covered by two back plates 122, so that the drag chain 3 is completely hidden in the accommodating cavity and will not be exposed. The cover plate 13 and the drag chain 3 are both located between the two sliding plates 212. The two side baffles 12 can cover the two sliding plates 212, hide the sliding structure, avoid external interference, and ensure the stability and reliability of the lifting of the moving component.

[0034] One end of the drag chain 3 is connected to a sliding plate 212 and the other end is connected to the support column 11. The built-in cable of the drag chain 3 is used to facilitate the circuit layout between the support column 11 and the sliding plate 212, thereby realizing the electrical connection between the host module 91 and the data interaction module 92.

[0035] like Figure 4 , Figure 5 As shown, the support column 11 includes a panel 111 and two outer panels 112. The two outer panels 112 are respectively connected to the lateral edges of the panel 111. The two outer panels 112 are arranged opposite to each other and are respectively fixedly connected to two docking plates 121. The matching structure of the panel 111 and the two outer panels 112 can form a certain accommodation space, thereby increasing the space of the accommodation cavity, facilitating the arrangement of structures such as the drag chain 3, and can improve the structural strength of the support column 11.

[0036] A structural plate 14 is fixed inside the support column 11. The structural plate 14 is located between the two outer plates 112 and is fixedly connected to the panel 111. Two guide rails 15 are arranged on the structural plate 14. Each sliding plate 212 is provided with a slider 25. The two sliders 25 are respectively slidably connected to the two guide rails 15. The structural plate 14 can be used to conveniently set the guide rails 15, avoid deformation of the panel 111 structure located on the front of the support column 11, and ensure the flatness and aesthetics of the panel 111.

[0037] The lifting mechanism 100 with a built-in drag chain 3 also includes a driving component 4 for driving the moving component 2 to move up and down. The driving component 4 includes a motor 41, a transmission belt 43 and two pulleys 42. The two pulleys 42 are arranged along the axial direction of the support column 11 and are rotatably set on the structural plate 14. The two ends of the transmission belt 43 are respectively connected to the two pulleys 42, and the side belts on both sides are arranged in the horizontal direction, and one side belt is fixedly connected to a sliding plate 212. The motor 41 is fixed at the bottom of the column 1 and is connected to a pulley 42 to drive the transmission belt 43 to move and thereby drive the moving component 2 to move up and down.

[0038] A receiving plate 16 is provided on the side of the structural plate 14 facing away from the panel 111. The receiving plate 16 is located between the two sliding plates 212. The receiving plate 16 is a strip arranged along the length direction of the support column 11, and its cross section is L-shaped, including an inner plate 161 and an isolation plate 162. The inner plate 161 is located on the side of the isolation plate 162 close to the other sliding plate 212. The inner plate 161 abuts against the side of the cover plate 13 facing the support column 11, and can support the cover plate 13. The other end of the drag chain 3 is connected to the inner plate 161 and is located on the side of the isolation plate 162 facing the cover plate 13. The isolation plate 162 can reduce the receiving space of the drag chain 3, so that its range of movement is limited between the isolation plate 162 and the cover plate 13, so as to prevent the drag chain 3 from shaking and affecting its structural strength.

[0039] The two ends of the isolation plate 162 in the length direction are bent toward the structural plate 14 and fixedly connected to the structural plate 14, and the other side of the transmission belt 43 is arranged between the isolation plate 162 and the structural plate 14. The isolation plate 162 can be used to isolate the conveyor belt from the drag chain 3 to avoid interference between the two movements.

[0040] The side of the cover plate 13 facing the back plate 122 is provided with a boss 131, which is located between the two back plates 122 and is in the shape of a long strip arranged along the axial direction of the support column 11. The middle plate 211 is bent in the middle position in the horizontal direction toward the side away from the cover plate 13, and the side of the middle plate 211 facing the cover plate 13 forms a groove 216 that matches with the boss 131, and the side away from the cover plate 13 forms a protrusion 217, which is located between the two back plates 122. The protrusion 217 can facilitate the assembly connection between the middle plate 211 and other structures, and the cooperation between the groove 216 and the boss 131 can ensure the stability of the lifting and lowering movement of the middle plate 211.

[0041] The edge of each back plate 122 away from the docking plate 121 is bent toward the cover plate 13 to form a folded edge 123; a receiving groove 218 is provided on the middle plate 211 corresponding to the folded edge 123, and the folded edge 123 extends into the receiving groove 218. By utilizing the folded edge 123 and the receiving groove 218, the gap between the middle plate 211 and the back plate 122 can be narrowed, and the gap between the two can be made more tortuous, thereby preventing foreign debris from entering the receiving cavity through the gap between the back plate 122 and the middle plate 211 and affecting the performance of the equipment.

[0042] like Figure 4 , Figure 6 As shown, the mobile assembly 2 also includes an adapter plate 22, two lifting side plates 23, and a mounting plate 24 for mounting the data interaction module 92. The adapter plate 22 is fixedly connected to the protrusion 217, the two lifting side plates 23 are respectively fixedly connected to the lateral sides of the adapter plate 22, the mounting plate 24 is fixedly connected to the two lifting side plates 23, and the column 1 is located between the two lifting side plates 23 and between the adapter plate 22 and the mounting plate 24. The data interaction module 92 can be installed on the side of the mounting plate 24 away from the middle column 1, and the mounting plate 24 is located on the side of the panel 111 of the column 1, so that the data interaction module 92 can be located at the front of the column 1, and the front of the column 1 has a simple structure and improves the aesthetics; and the back plate 122, the cover plate 13, and the middle plate 211 are all located at the back of the column 1, that is, the drag chain 3 can be hidden from the back of the column 1 to prevent the user from improperly operating and putting personal items into the accommodating cavity.

[0043] The mobile component 2 also includes a sheet metal part 29, which covers the outer periphery of the adapter plate 22 and the two lifting side plates 23. The circuit between the drag chain 3 and the data interaction module 92 can be arranged on the adapter plate 22 and the two lifting side plates 23. The sheet metal part 29 can protect the adapter plate 22 and the lifting side plates 23, and at the same time protect the circuit structure on the two.

[0044] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention.
