[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 As shown, a medical anti-theft airtight transfer window includes a base 1, a box body 2 is provided on the top of the base 1, a first window 3 is provided on the front side of the box body 2, and the lock body of the first window 3 adopts an electronic lock body, and a second window 4 is provided on the rear side of the box body 2. The lock body of the second window 4 adopts an electronic lock body. The first window 3 and the second window 4 cannot be opened at the same time. It is characterized by further comprising:

[0046] A first mounting plate 301 is provided at the bottom of the first window 3, and a second mounting plate 401 is provided at the bottom of the second window 4;

[0047] The top of the base 1 is rotatably connected to a placement component 5, which is located in the box 2. The placement component 5 includes a placement plate, the bottom of which is rotatably connected to the top of the base 1, and a partition plate 501 is provided on the top of the placement plate;

[0048] A limit frame 102 is fixedly connected to the bottom of the inner cavity of the base 1, and a sliding channel is formed between the limit frame 102 and the inner wall of the base 1;

[0049] The front and rear sides of the base 1 are symmetrically provided with first sliding holes 101. The first driving block 6 is slidably connected to the first sliding hole 101 on the front side, and the second driving block 13 is slidably connected to the first sliding hole 101 on the rear side.

[0050] A first spring 601 is fixedly connected to one side of the first driving block 6 away from the limiting frame 102, and the other end of the first spring 601 is fixedly connected to the first mounting plate 301. When the first window 3 is opened, the first window 3 drives the first driving block 6 to slide along the first sliding hole 101 through the first spring 601. When the first window 3 is closed, the first window 3 drives the first driving block 6 to move in the opposite direction along the first sliding hole 101 and reset through the first spring 601. The movement trajectory of the first driving block 6 driven by the opening and closing of the first window 3 forms a door opening and closing motion trajectory.

[0051] A second spring 1301 is fixedly connected to the side of the second driving block 13 away from the limiting frame 102, and the other end of the second spring 1301 is fixedly connected to the second mounting plate 401. When the second window 4 is opened, the second window 4 will drive the second driving block 13 to slide along the second sliding hole 103 through the second spring 1301. When the second window 4 is closed, the second window 4 will drive the second driving rod to move in the opposite direction along the second sliding hole 103 and reset through the second spring 1301. The movement trajectory of the second driving block 13 driven by the second window 4 after opening and closing also forms a door opening and closing motion trajectory.

[0052] The left and right sides of the limit frame 102 are symmetrically provided with second sliding holes 103. The first driven block 7 is slidably connected to the second sliding hole 103 on the left side, and the second driven block 14 is slidably connected to the second sliding hole 103 on the right side. The first driven block 7 is fixedly connected to the side away from the base 1 with a first tooth plate 702, and the second driven block 14 is fixedly connected to the side away from the base 1 with a second tooth plate 1402.

[0053] A first connecting assembly is provided between the first driving block 6 and the first driven block 7. When the first driving block 6 moves, the first connecting assembly drives the first driven block 7 to slide along the second sliding hole 103, thereby driving the first tooth plate 702 to move and reset. A second connecting assembly is provided between the second driving block 13 and the second driven block 14. When the second driving block 13 moves, the second connecting assembly drives the second driven block 14 to slide along the second sliding hole 103, thereby driving the second tooth plate 1402 to move and reset.

[0054] The center of the base 1 is rotatably connected to a first gear rod 801, and the top of the first gear rod 801 is fixedly connected to a first gear 8. The top axis of the first gear 8 is fixedly connected to the bottom axis of the placement plate through a connecting rod that passes through the top of the base 1. Two sets of gear mechanisms are symmetrically arranged on both sides of the center of the first gear 8. When the first gear plate 702 or the second gear plate 1402 completes a door opening and closing motion trajectory, they can respectively drive the first gear 8 to rotate 180° clockwise through the gear mechanism, thereby driving the placement assembly to rotate 180° clockwise;

[0055] The gear mechanism includes a third gear 10 assembly and a first gear 8 assembly. Two groups of third gear 10 assemblies are rotatably connected to the top of the inner cavity of the base 1. The two groups of third gear 10 assemblies are symmetrically arranged with the first gear 8 as the axis center. The third gear 10 assembly includes a third gear rod 1001. The top of the third gear rod 1001 is fixedly connected to a third gear 10 that meshes with the first gear 8. The third gear 10 has the same gear ratio as the first gear 8. The top of the third gear 10 is provided with a first ratchet assembly for limiting the third gear 10 to rotate only counterclockwise. The third gear rod 1001 is also provided with a half gear 1002. The gear ratio of the half gear 1002 is the same as that of the first gear plate 702 and the second gear plate 1402.

[0056] Two groups of second gear 9 assemblies are provided in a rotating connection at the top of the inner cavity of the base 1. The two groups of second gear 9 assemblies are symmetrically arranged on both sides of the two groups of first gear 8 assemblies with the first gear 8 as the axis. The second gear 9 assembly includes a second gear rod 901. The bottom rotation connection of the second gear rod 901 is provided at the top of the base 1. The top rotation connection of the second gear rod 901 is provided with a second gear 9 meshing with the half gear 1002. The bottom of the second gear 9 is provided with a second ratchet assembly for only driving the second gear 9 to rotate clockwise. A transmission wheel 902 is also provided on the second gear rod 901. The transmission wheel 902 has the same gear ratio as the second gear 9.

[0057] In this embodiment, medical staff on both sides pass items through this device. When the medical staff on one side opens the first window 3, the first window 3 drives the first driving block 6 to move from left to right through the first mounting plate 301 and the first spring 601. The first driving block 6 drives the first driven block 7 and the first tooth plate 702 to move from back to front through the first connecting component. During this movement, the first tooth plate 702 contacts and engages with the transmission wheel 902 on the left, which will drive the second gear rod 901 on the left to rotate counterclockwise. Since the second ratchet assembly limits the third gear 10 to rotate only counterclockwise, the second gear 9 meshing with the third gear 10 can also only rotate clockwise. At this time, the second gear rod 901 on the left will rotate independently relative to the second gear 9 on the left. When the first window 3 is opened, the medical staff will place the transferred items on the placement plate on one side of the partition plate 501 or take out the items. The product is then processed, and the medical staff closes the first window 3. When the first window 3 is closed, the first connecting component drives the first tooth plate 702 to move from front to back and reset. During this movement, the first tooth plate 702 contacts and engages with the transmission wheel 902 on the left, which drives the second tooth bar 901 on the left to rotate clockwise. The second tooth bar 901 on the left drives the second gear 9 on the left to rotate clockwise through the first ratchet assembly. The second gear 9 on the left drives the third tooth bar 1001 to rotate counterclockwise through the half gear 1002, thereby driving the third gear 10 to rotate counterclockwise. Since the gear ratio of the first tooth plate 702 and the half gear 1002 is the same, during this process, the third tooth bar 1001 on the left will drive the first gear 8 to rotate 180° clockwise, thereby driving the placement plate to rotate 180° clockwise to rotate the placed transfer object to the other side.

[0058] Afterwards, the half gear 1002 is disengaged from the second gear 9, so opening and closing the first window 3 again cannot drive the half gear 1002 to rotate, and thus cannot drive the placement plate to rotate, thereby preventing the items from being stolen.

[0059] Similarly, when the second window 4 is opened, the medical staff on the other side takes out or places the delivery item and then closes the second window 4. With the cooperation of the second tooth plate 1402 and the transmission wheel 902 on the other side, the placement plate rotates 180° clockwise. At this time, the half gear 1002 on the same side as the first tooth plate 702 will rotate and reset to engage with the second gear 9 on the same side. Opening and closing the first window 3 again can drive the placement plate to rotate 180° clockwise again.

[0060] Preferably, multiple groups of hooks 502 are symmetrically provided on both sides of the partition plate 501; items can be hung on the hooks 502, which can make full use of the upper space and increase the number of items that can be placed on the placement plate.

[0062] When the medical staff opens the first window 3, the first window 3 drives the first driving block 6 to move from left to right through the first mounting plate 301 and the first spring 601, and the first driving block 6 drives the first driven block 7 and the first tooth plate 702 to move from back to front through the soft rope. At this time, the first return spring 705 deforms and stores energy. When the first window 3 is closed, the first driving block 6 moves from right to left, and the first return spring 705 releases the stored energy to drive the first driven block 7 to move from front to back and reset.

[0067] The cooperation between the second pawl 1004 and the outer ratchet 1003 can limit the third gear 10 to rotate only counterclockwise. The third gear 10 limits the third gear rod 1001 and the half gear 1002 to rotate only counterclockwise. When the half gear 1002 is engaged with the second gear 9, the half gear 1002 limits the second gear 9 to rotate only clockwise. Therefore, when the second gear rod 901 rotates counterclockwise, the second gear rod 901 will drive the first pawl 904 to slide in the inner ratchet 903. When the second gear rod 901 rotates clockwise, the second gear rod 901 will drive the second gear 9 to rotate synchronously through the first pawl 904.

[0068] Preferably, two groups of snap plates 15 are fixedly connected to the bottom of the inner cavity of the base 1. The two groups of snap plates 15 are symmetrically arranged on the left and right sides of the first gear rod 801. The inner sides of the snap plates 15 overlap the outer surface of the first gear rod 801. The inner sides of the snap plates 15 are provided with a snap groove 1502. The outer surface of the first gear rod 801 is symmetrically provided with two groups of elastic blocks 1501.

[0069] When the first gear rod 801 rotates 180° clockwise, the block 1501 will move into the slot 1502 along the snap plate 15, thereby limiting the first gear rod 801 and preventing the first gear rod 801 from rotating excessively and causing deviation due to inertia. At the same time, since the block 1501 is elastic, when an external force drives the first gear rod 801 to rotate, the block 1501 will be compressed and deformed and squeezed out of the slot 1502.

[0070] Preferably, an anti-theft component for limiting the placement component 5 is provided in the box body 2;

[0071] The anti-theft component includes a first electric drive rod 12 and a second electric drive rod 16, which are both electrically connected to the external controller. The first electric drive rod 12 and the second electric drive rod 16 are fixedly connected on the left and right sides of the inner cavity of the box body 2, respectively, and the first electric drive rod 12 is located on the front side of the partition plate 501, and the second electric drive rod 16 is located on the rear side of the partition plate 501. Two groups of sensors 11 are provided on the inner wall of the base 1. The two groups of sensors 11 are centrally symmetrically arranged on both sides of the limit frame 102 and at the top of the sliding channel. The sensor 11 on the left is located in front of the first gear 8, and the sensor 11 on the right is located on the rear side of the first gear 8. Signal transmitters are respectively provided on the top of the first connecting plate 701 and the second connecting plate 1401. When the signal transmitter passes the bottom of the sensor 11, it will transmit the signal to the external controller. After receiving the signal, the external controller will control the opening and closing of the first electric drive rod 12 and the second electric drive rod 16 respectively.

[0072] When the first window is opened, the first window 3 drives the first driving block 6 to move from left to right through the first mounting plate 301 and the first spring 601, and the first driving block 6 drives the first driven block 7, the first connecting plate 701 and the first tooth plate 702 to move from back to front through the first connecting assembly. During this movement, the signal transmitter on the top of the first connecting plate 701 passes the bottom of the left sensor 11 once. After the left sensor 11 receives the signal, it will transmit the signal to the external controller. After receiving the signal, the external controller controls the first electric drive rod 12 to extend to limit the partition plate 501. That is, when the first window 3 is opened, the first electric drive rod 12 will limit the placement plate. At this time, the placement plate cannot be pushed to rotate by external force. When the first window 3 is closed, the first connecting plate 701 will pass the bottom side of the left sensor 11 again. After receiving the signal, the left sensor 11 will transmit the signal to the external controller. After receiving the signal, the external controller will control the first electric drive rod 12 to reset, thereby releasing the limit on the partition plate 501.

[0073] Similarly, when the second window 4 is opened, the second electric drive rod 16 will limit the placement plate, and when the second window 4 is closed, the second electric drive rod 16 will reset to release the limit on the partition plate 501;

[0074] During use, when the medical staff opens the window on the placement side to place items, and the medical staff on the other side does not take the items out of the window on the other side in time, the half gear 1002 is set, and the window on the placement side is opened again and the placement plate cannot be driven to rotate. At the same time, the first electric drive rod 12 also limits the placement plate to prevent criminals from forcibly pushing the placement plate to rotate and stealing items, thereby improving the anti-theft performance of the device and preventing items from being stolen.

[0075] The medical anti-theft airtight transfer window provided by the present invention has the following features: when a medical worker on one side opens the first window 3 and then places or takes out an item on the storage plate, when the first window 3 is closed, the storage plate will rotate 180°, and the medical worker on the other side opens the second window 4 to take out or place the item, and when the second window 4 is closed, the storage plate will continue to rotate 180° to complete the transfer of the item; and, through the provided half gear 1002, after the window on one side completes a complete opening and closing process and drives the storage plate to rotate 180°, and before the window on the other side is opened and closed, the window on this side will not drive the storage plate to rotate 180° again if it is opened and closed multiple times. The person on this side cannot see or take out the item due to the obstruction of the partition plate 501, thereby avoiding the medical worker on this side failing to take out the item in time, causing passers-by on this side to see the item in the box and take it out, thereby improving the anti-theft performance of the device.
