With further reference to fig. 1, 2 and 3, the rotary lifting mechanism 100 includes a first driving device 10 and a rotating mechanism 20 connected to the first driving device 10 up and down. Specifically, the rotating mechanism 20 includes a second driving device 21 connected to the first driving device 10 in an up-and-down rotating manner, a screw rod 22 connected to the second driving device 21 in a rotating manner, and a lifting mechanism 23 sleeved on the screw rod 22; one end of the lifting mechanism 23 away from the second driving device 21 is used for connecting the functional device.

With further reference to fig. 3, the rotary lifting mechanism 100 further comprises a speed reducer (not shown) having one end connected to one end of the first driving device 10 and the other end connected to the second driving device 21.

With further reference to fig. 3, the lifting mechanism 23 includes a linear bearing 231, a lifting joint 232, and a tubular structure 233. The linear bearing 231 is sleeved on the screw rod 22, the lifting joint 232 is sleeved on and fixedly connected to the linear bearing 231, and the cylindrical structure 233 is sleeved on the screw rod 22 and fixedly connected to the linear bearing 231 and the lifting joint 232. The lead screw 22 rotates to drive the linear bearing 231, the lifting joint 232 and the cylindrical structure 233 to move up and down linearly.
Specifically, in this embodiment, the second driving device 21 is, but not limited to, a servo motor, the lead screw 22 is connected to the second driving device 21 through a coupling, and the coupling transmits the rotating force of the second driving device 21 to the lead screw 22 to drive the linear bearing 231 on the lead screw 22 to move linearly up and down, so as to drive the lifting joint 232 fixedly connected to the linear bearing 231 and the cylindrical structure 233 fixedly connected to the lifting joint 232 and the linear bearing 231 to move linearly up and down.
With further reference to fig. 3, the cylindrical structures 233 are both fixedly connected to the linear bearing 231 and the lifting joint 232. Specifically, the tubular structure 233 includes an inner tube 2331 and an intermediate tube 2332 which are arranged at an interval, the inner tube 2331 is connected with the linear bearing 231 up and down and sleeved outside the screw rod 22, and the intermediate tube 2332 is connected with the lifting node 232 up and down and sleeved outside the inner tube 2331.

With reference to fig. 3 and 4, a vertical limiting groove 241 is formed on the side wall of the outer cylinder 24 and penetrates through the outer cylinder 24 along the extending direction of the screw rod 22. The lifting mechanism 23 further comprises a boss fixedly connected with the lifting joint 232, and the boss penetrates through and is connected with the vertical limiting groove 241 in a sliding manner;
in an embodiment, the lifting joint 232 drives the boss 25 to slide up and down along the vertical limiting groove 241 when moving linearly up and down, and due to the existence of the vertical limiting groove 241, the lifting mechanism 23 does not rotate relative to the screw rod 22 when moving linearly up and down, that is, the lifting mechanism 23 is kept stationary relative to the screw rod 22 when moving linearly up and down.
Referring to fig. 3 and 4, the lifting mechanism 23 further includes a wire winding ring 30 sleeved on the outer cylinder 24 and a spring 40 wound on the outer cylinder 24, wherein the wire winding ring 30 is located between the boss 25 and the spring 40. One end of the wire coiling ring 30 is connected with one end of the boss 25 penetrating through the vertical limiting groove 241, and the other end is connected with the spring 40. When the boss 25 moves linearly up and down along the vertical limiting groove 241, the wire winding ring 30 is driven to move linearly up and down, so that the spring 40 is compressed or stretched.
With combined reference to fig. 4 and 5, the rotary lifting mechanism 100 of the lifting mechanism 23 further includes a mounting plate 50, and an upper fixing plate 60 and a lower fixing plate 70 fixedly disposed on one side of the mounting plate 50 and oppositely disposed. The outer cylinder 24 is disposed between the upper fixing plate 60 and the lower fixing plate 70. The lower fixing plate 70 is provided with a rotation limiting groove 80 penetrating through the lower fixing plate, and an output shaft of the first driving device 10 penetrates through the rotation limiting groove 80 of the lower fixing plate 70 and the outer cylinder 24 and is connected with the second driving device 21; the portion of the elevating mechanism 23 beyond the outer cylinder 24 passes through the upper fixing plate 60.
In this embodiment, the rotation-limiting groove 80 may limit the rotation of the entire rotation mechanism 20 within the range of the rotation-limiting groove 80.
Further, the rotary lifting device 200 according to an embodiment of the present application further includes a controller (not shown) and at least one circuit line (not shown) connecting the controller and the function device 300; in this embodiment, the function device 300 receives the signal of the controller through the circuit line, and the controller controls the function device 300 to implement a corresponding function, where the function is face collection, face recognition, fingerprint collection, fingerprint recognition or face fingerprint collection, but the function is not limited thereto. In one embodiment, the controller is an embedded chip.
In this embodiment, each circuit line enters the lifting mechanism 23 from one end of the lifting mechanism 23 away from the second driving device 21, penetrates through the lifting mechanism 23, penetrates out of the lifting mechanism 23 from the vertical limiting groove 241, rotates the lifting mechanism 100, and is electrically connected to the controller; a gap between the middle cylinder 2332 and the inner cylinder 2331 is used for accommodating each of the circuit lines entering the elevating mechanism 23, and the wire winding ring 30 and the spring 40 are used for winding each of the circuit lines coming out from the rotating elevating mechanism 100 of the elevating mechanism 23. It will be appreciated that each of the circuit lines passes out of the rotary mechanism 20, i.e., the circuit lines pass through the middle cylinder 2332 and the outer cylinder 24; the circuit wire passing through the outer barrel 24 is wound around the wire loop 30 and the spring 40.
In this way, since the circuit line connected to the functional device 300 is located between the middle cylinder 2332 and the inner cylinder 2331, the circuit line of the functional device 300 is not in direct contact with the screw rod 22, thereby effectively preventing the circuit line from being damaged; the functional device 300 rotates and moves up and down along with the rotation of the lifting mechanism 100 by the lifting mechanism 23, the circuit wire connected with the functional device 300 is necessarily dragged during the rotation and movement, while in the present embodiment, the circuit wire extending out from the outer cylinder 24 may be wound around the wire winding ring 30 and the spring 40, and when the functional device 300 moves along with the rotation mechanism 20, the spring 40 is also stretched and compressed, so that the circuit wire is protected during the dragging.
Example two:
referring to fig. 6, a pinging device 400 is provided according to a second embodiment of the present application, where the pinging device 400 includes at least two gate bodies disposed in parallel and opposite to each other, and two adjacent gate bodies form a pinging channel. The pinging device 400 further comprises the lifting mechanism 23 described above to rotate the lifting mechanism 100 and the functional means 300. The lifting mechanism 23 of the second embodiment is identical to the rotary lifting machine of the first embodiment in the rotary lifting mechanism 100. The functional apparatus 300 in the second embodiment is identical to the functional apparatus 300 in the first embodiment. The inspection device 400 is a device for inspecting a customs clearance person and performing a prohibition of customs clearance or a release of pass-through operations by the inspection information; the inspection channel is a walking channel for the cleared customs clearance personnel.
In this embodiment, the first driving device 10 and the second driving device 21 of the lifting mechanism 23 for rotating the lifting mechanism 100 are located in one of the gate bodies, and the lifting mechanism 23 is partially located in the gate body; the function device 300 is connected to a portion of the elevating mechanism 23 beyond the gate body. The lifting mechanism 23 rotates the lifting mechanism 100 for rotating the functional device 300 into or out of the inspection channel and for adjusting the height of the functional device 300.
It is understood that, when the inspection person needs to use the functional device 300 during the inspection process, in order to facilitate the inspection person to use the functional device 300, the lifting mechanism 100 needs to be rotated by the lifting mechanism 23 to move the functional device 300 into the inspection passage, and the lifting mechanism 100 needs to be rotated by the lifting mechanism 23 to adapt to the height of the functional device 300 for the inspection person with different heights. When passing the customs clearance, in order to prevent the functional device 300 from occupying the inspection passage, the functional device 300 needs to be rotated out of the passage so that the customs clearance can walk in the inspection passage.
In the inspection apparatus 400, the lifting mechanism 23 rotates the lifting mechanism 100 to be able to rotate and move the functional device 300 up and down so that it can accommodate different orientations and heights from the functional device 300; in addition, the functional device 300 does not need to be arranged in the inspection channel so as to facilitate the customs officer to use the functional device 300, thereby causing the problem of occupying the space of the inspection channel, and the space of the inspection channel is saved.
The checking apparatus 400 further includes a controller located in the gate body and at least one circuit line (not shown) connecting the controller (not shown) and the functional device 300, wherein the circuit line enters the lifting mechanism 23 from one end of the lifting mechanism 23 away from the second driving device 21, penetrates through the lifting mechanism 23, penetrates out of the lifting mechanism 23 from the vertical limiting groove 241, rotates the lifting mechanism 100, and is electrically connected to the controller; a gap between the middle cylinder 2332 and the inner cylinder 2331 is used for accommodating each of the circuit lines entering the elevating mechanism 23, and the wire winding ring 30 and the spring 40 are used for winding each of the circuit lines coming out from the rotating elevating mechanism 100 of the elevating mechanism 23. In this embodiment, the function device 300 receives the signal of the controller through the circuit line, and the controller controls the function device 300 to implement a corresponding function, where the function is face collection, face recognition, fingerprint collection, fingerprint recognition or face fingerprint collection, but the function is not limited thereto. In one embodiment, the controller is an embedded chip.
In this embodiment, the checking apparatus 400 further includes a controller located in the gate body and at least one circuit line connecting the controller and the functional device 300, where the circuit line enters the lifting mechanism 23 from one end of the lifting mechanism 23 away from the second driving device 21, penetrates the lifting mechanism 23, and penetrates the lifting mechanism 23 through the vertical limiting groove 241 and is electrically connected to the controller, and the rotating lifting mechanism 100 is rotated by the lifting mechanism 23; a gap between the middle cylinder 2332 and the inner cylinder 2331 is used for accommodating each of the circuit lines entering the elevating mechanism 23, and the wire winding ring 30 and the spring 40 are used for winding each of the circuit lines coming out from the rotating elevating mechanism 100 of the elevating mechanism 23. Since the lifting mechanism 23 of the second embodiment rotates the lifting mechanism 100 the same as the lifting mechanism 23 of the first embodiment rotates the lifting mechanism 100, it can be understood that each of the circuit lines passes through the rotating mechanism 20, i.e. the circuit lines pass through the middle cylinder 2332 and the outer cylinder 24; the circuit wire passing through the outer barrel 24 is wound around the wire loop 30 and the spring 40.
In this way, since the circuit line connected to the functional device 300 is located between the middle cylinder 2332 and the inner cylinder 2331, the circuit line of the functional device 300 is not in direct contact with the screw rod 22, thereby effectively preventing the circuit line from being damaged; the functional device 300 rotates and moves up and down along with the rotation of the lifting mechanism 100 by the lifting mechanism 23, the circuit wire connected with the functional device 300 is necessarily dragged during the rotation and movement, while in the present embodiment, the circuit wire extending out from the outer cylinder 24 may be wound around the wire winding ring 30 and the spring 40, and when the functional device 300 moves along with the rotation mechanism 20, the spring 40 is also stretched and compressed, so that the circuit wire is protected during the dragging.
