[0050] Example 2

[0051] Reference Figures 1-9 This is the second embodiment of the present invention. In the previous embodiment, the bidirectional transfer window includes a box body 1 and a window mechanism 2. By setting the window mechanism 2 on the box body 1, it is possible to seal or open one or both sides of the box body 1.

[0052] Specifically, it includes a housing 1 and a window mechanism 2; the housing 1 is equipped with a window mechanism 2, which can provide one-way or two-way sealing and isolation for the housing 1;

[0053] The form mechanism 2 includes a drive component 21 and a push door limit component 22; the drive component 21 can drive the push door limit component 22 to switch the box 1 on one or both sides.

[0054] Preferably, the drive component 21 can drive the push door limit component 22, thereby allowing the push door limit component 22 to seal or open one or both sides of the housing 1.

[0055] Furthermore, at least two sets of push door limit components 22 are provided, and the drive component 21 is provided between the two sets of push door limit components 22. The drive component 21 can drive the two sets of push door limit components 22 to open and close the housing 1 respectively.

[0056] Preferably, by setting the push door limit assembly 22 into two sets, and using the drive assembly 21 to drive the push door limit assembly 22 separately, it is possible to achieve the closing of one side of the cabinet 1 and the opening of the other side, or the closing of both sides.

[0057] Preferably, the drive component 21 drives the push door limit component 22 separately, so that the push door limit component 22 can open and close the box 1 separately, ensuring that the gas flow in the two sides of the sample is avoided during the transfer process, thus ensuring the safety of the biological sample environment.

[0058] Furthermore, the push door limit assembly 22 includes a rotating door component 221, a sliding component 222, and a rotation limit component 223; the sliding component 222 is connected to the rotating door component 221, and the rotation limit component 223 is provided on the sliding component 222; the drive assembly 21 performs opening and closing operations on the rotating door component 221 through the sliding component 222 and the rotation limit component 223.

[0059] Furthermore, the slider 222 includes a slide rail 2221 and a slider block 2222; the slider block 2222 is disposed on the slide rail 2221 and can slide on the slide rail 2221.

[0060] Preferably, the sliding member 222 and the rotation limit member 223 can be driven by the drive component 21. By changing the direction of movement of the drive component 21, the rotating door member 221 can be used to open and close the housing 1.

[0061] Preferably, by setting two sets of sliding blocks 2222 on the slide rail 2221 and setting the drive assembly 21 between the two sets of slide rail 2221, the drive assembly 21 can push the rotating door 221 through the drive sliding blocks 2222 and the rotation limiter 223 respectively, so as to seal or open the box 1.

[0062] It should be noted that when the drive assembly 21 is working on one set of push door limit assemblies 22, the other set of push door limit assemblies 22 is in a sealed state with the housing 1; when the drive assembly 21 is working on both sets of push door limit assemblies 22, both sets of push door limit assemblies 22 are in a sealed state with the housing 1.

[0063] Furthermore, the rotation limiter 223 includes a rotating shaft 2231 and a hook body 2232; the rotating shaft 2231 is connected to the sliding member 222, the hook body 2232 is disposed on the rotating shaft 2231, the hook body 2232 can rotate on the rotating shaft 2231, and the drive assembly 21 can hook and push the hook body 2232.

[0064] Preferably, the hook body 2232 can rotate around the pivot 2231. The drive assembly 21 can drive the hook body 2232 to move the sliding block 2222, thereby pushing the rotating door 221 to close the box 1.

[0065] Furthermore, the drive assembly 21 includes a drive member 211, on which a push module 212 is provided. The push module 212 is mounted on a slide rail 2221 and can cooperate with a sliding block 2222 or a rotation limit member 223.

[0066] Preferably, the drive unit 211 includes a motor drive unit and a lead screw. The motor drive unit drives the lead screw to rotate, and the lead screw engages with the push module 212 to drive the push module 212 forward or backward.

[0067] Furthermore, the push module 212 includes a push slider 2121, on which a push rod 2122 is provided. The push rod 2122 cooperates with the rotation limit member 223. The push rod 2122 can drive the rotation limit member 223 and the sliding block 2222 to move towards the middle position of the housing 1, and the push slider 2121 can push the sliding block 2222 to move towards the opening end of the housing 1.

[0068] Preferably, the slider 2121 is pushed to move on the slide rail 2221.

[0069] Furthermore, the hook body 2232 is provided with a hooking part 22321 and a guide part 22322; the hooking part 22321 has a certain recessed depth, and the guide part 22322 is inclined and is a slope at a certain angle. The drive component 21 can enter the hooking part 22321 through the guide part 22322. The guide part 22322 can guide the drive component 21, and the hooking part 22321 can limit the drive component 21.

[0070] Preferably, the guide part 22322 is set at a certain tilt angle. When the push slider 2121 drives the push rod 2122 to move, when the push rod 2122 contacts the guide part 22322, it will enter along the path of the guide part 22322, causing the hook body 2232 to rotate along the rotating shaft 2231, so that the push rod 2122 enters the hook part 22321. The hook part 22321 can limit the push rod 2122. The drive member 211 pushes the push rod 2122 on the push slider 2121 to move, which will drive the hook body 2232 and the sliding block 2222 to move. The sliding block 2222 drives the rotating door member 221 to close and seal the box 1.

[0071] Furthermore, the push door limit assembly 22 is also provided with a contact element 224 and a blocking element 225; the contact element 224 is provided on the hook body 2232, and the blocking element 225 is provided in the middle of the side wall of the housing 1. When the contact element 224 contacts the blocking element 225, the hook body 2232 can rotate around the rotating shaft 2231.

[0072] Preferably, the touch element 224 includes a touch rod with a pivot on it; the blocking element 225 includes a blocking block, and one blocking element 225 is provided for each set of push door limit assembly 22.

[0073] When the contact member 224 contacts the blocking member 225, the drive assembly 21 will also drive the hook body 2232 to move. However, under the action of the blocking member 225, the contact member 224 will drive the hook body 2232 to rotate along the rotating shaft 2231, thereby causing the push rod 2122 on the push slider 2121 to disengage from the hook part 22321 on the hook body 2232. Therefore, the rotation limit member 223 stops moving, and at this time the rotating door member 221 is in the closed state with the box 1.

[0074] When opening the door, the drive unit 211 drives the push slider 2121 and the push rod 2122 to move on the slide rail 2221. The push slider 2121 pushes the sliding block 2222, which in turn pushes the connecting rod 2211. The connecting rod 2211 then pushes the rotating door 2212 to rotate, thus opening the door. When pushing, the push rod enters the hook part 22321 so that when closing the door, the push rod 2122 can hook the hook part 22321.

[0075] Furthermore, the push door limit assembly 22 also includes a spring-loaded component 226; one end of the spring-loaded component 226 is connected to the slider 222, and the other end is connected to the lower end of the hook body 2232. The spring-loaded component 226 can drive the hook body 2232 to return to the initial position around the pivot 2231.

[0076] Preferably, the function of the spring-loaded component 226 is that after the door is closed and the drive assembly 21 moves away from the hook part 22321, the spring force of the spring-loaded component 226 will cause the hook body 2232 to rotate around the pivot 2231 and return to the initial position for easy use next time.

[0077] Preferably, the spring-loaded element 226 can be a spring or an existing elastic device. The spring-loaded element 226 can be used to return the hook body 2232 to its initial position, or to make it fit tightly when the push rod 2122 pulls the hook part 22321.

[0078] Furthermore, the push door limiting assembly 22 also includes a limiting rod 227, which is disposed on the sliding member 222 and can limit the rotation of the hook body 2232.

[0079] Preferably, the function of setting the limiting rod 227 is to prevent the spring-loaded part 226 from pulling the hook body 2232 out of place. The limiting rod 227 can limit the rotation angle of the hook body 2232.

[0080] Furthermore, the rotating door component 221 includes a connecting rod 2211, a rotating door 2212, a magnetic component 2213, and a sliding block 2222; the two ends of the connecting rod 2211 are respectively connected to the rotating door 2212 and the sliding block 2222, the magnetic component 2213 is disposed on the side of the opening end of the housing 1, the sliding block 2222 can push the rotating door 2212 to rotate through the connecting rod 2211, and the magnetic component 2213 can fix the rotating door 2212.

[0081] Preferably, the movement of the sliding block 2222 drives the connecting rod 2211 to work, so that the rotating door 2212 can rotate around one end of the connecting rod 2211 to realize the operation of opening or closing the door.

[0082] Preferably, the magnetic component 2213 is used to fix the rotating door 2212 when it is attached to the box body 1.

[0083] Furthermore, it also includes a transfer mechanism 3, which is located inside the housing 1. The transfer mechanism 3 can drive the target object to extend out of the housing 1 in both directions or in one direction.

[0084] Furthermore, the transfer mechanism 3 includes a tray assembly 31 and a tray drive assembly 32; the tray drive assembly 32 can drive the tray assembly 31 to move clockwise or counterclockwise.

[0085] Preferably, the pallet assembly 31 includes a pallet with a positioning element on it, which can limit and fix the target part.

[0086] Preferably, the pallet drive assembly 32 includes a chain, a chain drive component, and a guide rail. By setting chain protrusions on the chain, the pallet can be moved. The guide rail can guide and limit the pallet. The chain drive component can drive the chain.

[0087] Preferably, the pallet drive assembly 32 can be driven by a chain, or by other drive methods, such as a belt pulley drive, or any existing drive method.

[0088] Preferably, the tray assembly 31 can be driven to move in different directions by rotating the tray drive assembly 32 in the forward or reverse direction.

[0089] Preferably, when it is necessary to transfer items from left to right, the drive assembly 21 is first used to open the push door limit assembly 22 on the left side of the box 1. Then, the transfer mechanism 3 extends out of the left side of the box 1. After the transfer mechanism 3 receives the item, it returns to the inside of the box 1. Then, the drive assembly 21 is used to close the left push door limit assembly 22, which is in the open state. At this time, the drive assembly 21 continues to move to open the right push door limit assembly 22. Then, the transfer mechanism 3 drives the item to extend out of the right side of the box 1. After the transfer is completed, the transfer mechanism 3 returns to the inside of the box 1. Finally, the drive assembly 21 closes the right push door limit assembly 22. At this time, the drive assembly 21 is in the middle position, waiting for the next use.

[0090] Furthermore, the housing 1 is also equipped with an electrical box mechanism 4 and a display mechanism 5. The electrical box mechanism 4 can drive the transmission mechanism 3 and the window mechanism 2 to work, and the display mechanism 5 can display and control the equipment process.

[0091] In summary, this utility model, by setting the window mechanism 2, allows the box 1 to be opened or closed from both sides or one side, thus protecting the sample during transport. The drive assembly 21 allows for the separate driving of two sets of push-door limit assemblies 22, ensuring that one set of push-door limit assemblies 22 operates simultaneously. This means that the two sets of push-door limit assemblies 22 can be opened, closed, and sealed separately for the box 1, saving space and cost while ensuring the sealing of each step. The hook part 22321 and guide part 22322 cooperate with the push module 212, facilitating the rotation of the hook body 2232 along the rotating shaft 2231, allowing the push rod 2122 to... The device allows for rapid entry into the hook section 22321; by setting a blocking member 225, the push rod 2122 can quickly disengage from the hook section 22321; by setting a spring-loaded member 226, the hook body 2232 can rotate along the pivot 2231 back to its initial position, facilitating the next hooking; by setting a transfer mechanism 3, the transfer mechanism 3 can drive the target object to move in two directions along the opening end of the box 1, thereby completing the transfer of items from one rotating door 2212 to the other rotating door 2212; the transfer mechanism 3 can achieve the two-way movement and extension of the tray with a single drive motor, saving the required space and reducing costs.
