[0002] With the development of the country, various types of pickup ports have appeared. However, in some scenarios such as schools or hospitals, when people need to pick up items without contact or even through a window, a two-way pickup port is needed. People outside can open the outside pickup door and put the items in the pickup port, and people inside can take the items by opening the inside door, so that the pickup port can serve as a temporary storage. In this way, people outside can put the items into the pickup port first, and it doesn’t matter if people inside come to pick them up later, and it also serves as an isolation function.
[0003] However, some of the two-way pickup ports are hand-pull doors, and both doors can be opened at the same time, which has little isolation effect.

The connecting rod module (5) comprises an inner connecting rod (51) and an outer connecting rod (52). Two connecting rod modules (5) are provided and both are located on one side of the picking shelf (1). The power module (4) is located on the other side of the picking shelf (1). One end of the inner connecting rod (51) is provided with an upper circular hole (511), and the other end is provided with a limiting inner hole (512). The upper circular hole (511) can be rotatably connected to the front fixed shaft (22) and the rear fixed shaft (32). The outer connecting rod (52) is provided with a limiting outer hole (521). , a lower circular hole (522), and a deep groove (523), wherein the lower circular hole (522) is rotatably connected to the lower fixed shaft (13), the inner connecting rod (51) is slidably matched with the deep groove (523), and the depth of the deep groove (523) is sufficient to allow the inner connecting rod (51) to slide and retract, and the limiting inner hole (512) and the limiting outer hole (521) are of the same size, and when the inner connecting rod (51) and the outer connecting rod (52) are at their extreme positions, the limiting inner hole (512) and the limiting outer hole (521) are coaxial. The limiting module (6) comprises a limiting cylinder (61) and a limiting block (62); the limiting cylinder (61) is fixedly connected below the picking shelf (1); the output end of the limiting cylinder (61) is fixedly connected to the limiting block (62); the limiting block (62) is provided with a front limiting column (621) and a rear limiting column (622); the front limiting column (621) and the rear limiting column (622) are of the same size; the front limiting column (621) and the rear limiting column (622) can both be clearance-matched with the limiting inner hole (512) and the limiting outer hole (521).When the limiting inner hole (512) and the limiting outer hole (521) are coaxial, the front limiting column (621) or the rear limiting column (622) can be directly inserted into the limiting inner hole (512) and the limiting outer hole (521), and when the limiting cylinder (61) is pushed out, the front limiting column (621) will only be stuck in the limiting inner hole (512) and the limiting outer hole (521) in the connecting rod module (5) on the side close to the picking shelf (1), and the rear limiting column (622) will not be stuck in the limiting inner hole (512) and the limiting outer hole (521) in any connecting rod module (5). When the limiting cylinder (61) is retracted, the rear limiting column (622) will only be stuck in the limiting inner hole (512) and the limiting outer hole (521) in the connecting rod module (5) on the outside, and the front limiting column (621) will not be stuck in the limiting inner hole (512) and the limiting outer hole (521) in any connecting rod module (5), so when one connecting rod module (5) is stuck, the other connecting rod module (5) will not be stuck.
[0029] Working principle:
[0030] Initial state: In the initial state, the front baffle (2) and the rear baffle (3) are located in front and behind the cargo pickup port (12), and the cargo can be temporarily stored in the cargo pickup port (12). The output end of the lifting cylinder (41) is ejected, and the gear (43) is located in the middle of the length direction of the front rack (21) and the rear rack (31). At this time, the inner connecting rod (51) and the outer connecting rod (52) in the two connecting rod modules (5) are both in the extreme position, and the respective limiting inner holes (512) and limiting outer holes (521) in the two connecting rod modules (5) are coaxial, and the output end of the limiting cylinder (61) remains in the retracted state, and the rear limiting column (622) is only inserted into the limiting inner hole (512) and the limiting outer hole (521) in the connecting rod module (5) on the outside.
[0031] The front baffle (2) is opened and closed: starting from the initial state, the output end of the limit cylinder (61) fixedly connected to the bottom of the picking shelf (1) is pushed out, driving the fixedly connected limit block (62) to move forward, and the front limit column (621) of the limit block (62) also moves forward. Because the limit inner hole (512) and the limit outer hole (521) in the connecting rod module (5) close to the side of the picking shelf (1) are coaxial, the front limit column (621) moves forward and can just be stuck in the limit inner hole (512) and the limit outer hole (521) in the connecting rod module (5) close to the side of the picking shelf (1). At this time, the limiting inner hole (512) and the limiting outer hole (521) in the connecting rod module (5) close to the side of the shelf (1) are stuck by the front limiting column (621), so that the inner connecting rod (51) cannot slide back in the deep groove (523). Since the upper circular hole (511) of the inner connecting rod (51) is rotatably connected to the rear fixed shaft (32), the rear baffle (3) is fixed, and the rear rack (31) on the rear baffle (3) is also fixed. However, the limiting inner hole (512) and the limiting outer hole (521) in the connecting rod module (5) close to the outside are not stuck, and the inner connecting rod (51) close to the outside can slide back in the deep groove (523). Since the upper circular hole (511) of the inner connecting rod (51) close to the outside is rotatably connected to the front fixed shaft (22), the front baffle (2) can also slide, and the front rack (21) on the front baffle (2) can also move. When the output end of the lifting cylinder (41) is retracted, the rear rack (31) is fixed, and the front rack (21) is movable. When the gear (43) moves downward, the rear rack (31) is fixed, so that the gear (43) changes from moving to rolling. The gear (43) causes the front rack (21) to move downward at twice the speed of the lifting cylinder (41) through rolling engagement. The front baffle (2) also slides downward smoothly through the sliding connection between the front slider (23) and the guide rail (11). When the lifting cylinder (41) is retracted to the right position, the front baffle (2) stops moving, and the connecting rod module (5) connected to the front baffle (2) also stops retracting. Because the connecting rod module (5) connected to the rear baffle (3) is stuck, the rear baffle (3) cannot be lowered, ensuring that the rear baffle (3) cannot be opened when the front baffle (2) is opened. At this time, the front door of the cargo pickup port (12) is opened, and the cargo pickup port (12) can be used to store and retrieve goods.The output end of the lifting cylinder (41) extends again, the rear rack (31) is fixed, the front rack (21) is movable, the gear (43) rolls, the front rack (21) moves upward at twice the speed of the lifting cylinder (41), the front baffle (2) slides upward, the inner connecting rod (51) connected to the front baffle (2) slowly slides out from the deep groove (523) of the outer connecting rod (52), when the lifting cylinder (41) is lifted into place, the front baffle (2) blocks the cargo pickup port (12) again, the inner connecting rod (51) and the outer connecting rod (52) in the connecting rod module (5) connected to the front baffle (2) are in the limit position, the output end of the limit cylinder (61) retracts, the rear limit column (622) is re-engaged in the limit inner hole (512) and the limit outer hole (521) in the connecting rod module (5) on the outside, and the entire mechanism is in the initial state.
[0032] Opening and closing of the rear baffle (3): starting from the initial state, the respective limiting inner holes (512) and limiting outer holes (521) in the two connecting rod modules (5) are coaxial, and the output end of the limiting cylinder (61) remains retracted. The rear limiting column (622) then clamps the limiting inner hole (512) and limiting outer hole (521) in the connecting rod module (5) on the outside, causing the inner connecting rod (51) on the outside to be unable to slide back in the deep groove (523). Since the upper circular hole (511) of the inner connecting rod (51) on the outside is rotatably connected to the front fixed shaft (22), the front baffle (2) is fixed and the front rack (21) on the front baffle (2) is also fixed. However, the limiting inner hole (512) and the limiting outer hole (521) in the connecting rod module (5) on the side close to the picking shelf (1) are not stuck, and the inner connecting rod (51) can slide back in the deep groove (523). Since the upper circular hole (511) of the inner connecting rod (51) is rotatably connected to the rear fixed shaft (32), the rear baffle (3) can also slide, and the rear rack (31) on the rear baffle (3) can also move. When the output end of the lifting cylinder (41) is retracted, the front rack (21) is fixed, and the rear rack (31) is movable. When the gear (43) moves downward, the front rack (21) is fixed, so that the gear (43) changes from moving to rolling. The gear (43) causes the rear rack (31) to move downward at twice the speed of the lifting cylinder (41) through rolling engagement, and the rear baffle (3) also slides downward smoothly through the sliding connection between the rear slider (33) and the guide rail (11). When the lifting cylinder (41) is retracted to the right position, the rear baffle (3) stops moving, and the connecting rod module (5) connected to the rear baffle (3) also stops retracting. Because the connecting rod module (5) connected to the front baffle (2) is stuck, the front baffle (2) cannot be lowered, ensuring that the front baffle (2) cannot be opened when the rear baffle (3) is opened. At this time, the rear door of the cargo pickup port (12) is opened, and the cargo pickup port (12) can also be used to store and retrieve goods. The output end of the lifting cylinder (41) extends again, the front rack (21) is fixed, the rear rack (31) is movable, the gear (43) rolls, the rear rack (31) moves upward at twice the speed of the lifting cylinder (41), the rear baffle (3) slides upward, the inner connecting rod (51) connected to the rear baffle (3) slowly slides out from the deep groove (523) of the outer connecting rod (52), and when the lifting cylinder (41) is lifted into place, the rear baffle (3) blocks the cargo pickup port (12) again, the inner connecting rod (51) and the outer connecting rod (52) in the connecting rod module (5) connected to the rear baffle (3) are in the extreme position, and all the mechanisms are in the initial state.
[0033] The above merely describes the specific implementation methods of the present invention, but the present invention is not limited thereto. Various improvements can be made without departing from the design concept of the present invention, all of which fall within the protection scope of the present invention.
