Description
Technical Field
[0001] The utility model relates to the technical field of transfer windows, and more specifically, to a fireproof transfer window. Background Art
[0002] Transfer windows are mainly used for the transfer of small items between clean areas or between clean areas and non-clean areas. By using a transfer window to transfer items, the number of times the clean room door is opened can be reduced, thereby reducing the pollution of the clean room by external air. Transfer windows usually adopt a design of double-door interlock, that is, the two side doors cannot be opened simultaneously, effectively preventing the air circulation between different cleanliness areas and avoiding cross-contamination.
[0003] Most of the existing transfer windows adopt a mechanical interlock method to achieve the effect of double-door interlock of the transfer window. The mechanical interlock has a simple structure, low cost, and is easy to maintain. However, the mechanical interlock requires manual operation of the bolt or latch, resulting in low efficiency during use. Therefore, a new solution that can improve the use efficiency of the transfer window needs to be proposed. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a fireproof transfer window, which reduces the probability of the inner and outer windows being opened simultaneously by setting a retractable structure below the inner window and the outer window.
[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: A fireproof transfer window includes a window body. Inner and outer windows are respectively rotatably connected to both ends of the window body in the length direction. A limiting device one connected to the inner window is arranged in the window body. One end of the limiting device one away from the inner window is located below the outer window. A sliding groove for one end of the limiting device one to move to abut against the outer window is opened on the window body. When the inner window rotates, one end of the limiting device one abuts against the outer window through the sliding groove. A limiting device two connected to the outer window is arranged in the window body. The limiting device two has the same structure as the limiting device one. When the outer window rotates, one end of the limiting device one abuts against the inner window through the sliding groove.
[0006] The present utility model is further arranged as follows: The limiting device one includes a connecting rod one and a lifting component one. The lifting component one is fixedly connected to one end of the connecting rod one close to the inner window and abuts against the lower surface of the inner window. The connecting rod one is slidably connected to the inner wall of the sliding groove. A blocking piece one is fixedly connected to one end of the connecting rod one close to the outer window. The blocking piece one is slidably connected inside the outer window. A clamping groove one for the blocking piece one to slide is opened on the lower surface of the outer window.
[0007] The present utility model is further configured as follows: The first lifting assembly includes a first moving block and a plurality of first elastic members. One ends of the plurality of first elastic members are fixedly connected to the lower surface of the first moving block, and the other ends of the plurality of first elastic members are fixedly connected to the bottom surface of the sliding groove. The first moving block abuts against the lower surface of the inner window.
[0008] The present utility model is further configured as follows: The structure of the second limiting device is the same as that of the first limiting device. The second limiting device includes a second connecting rod and a second lifting assembly. The second lifting assembly is fixedly connected to one end of the second connecting rod close to the outer window and abuts against the lower surface of the outer window. A second blocking piece is fixedly connected to one end of the second connecting rod close to the outer window. A second card slot for the second blocking piece to slide is formed in the lower surface of the inner window.
[0009] The present utility model is further configured as follows: The structure of the second lifting assembly is the same as that of the first lifting assembly. The second lifting assembly includes a second moving block and a plurality of second elastic members. The second moving block abuts against the lower surface of the outer window.
[0010] The present utility model is further configured as follows: The sides of the first moving block and the second moving block away from the sliding groove are arc-shaped. The length of the first moving block is greater than the depth of the first card slot, and the length of the second moving block is greater than the depth of the second card slot.
[0011] In summary, the present utility model has the following beneficial effects: A fireproof transfer window has two sliding grooves formed on the window body. Limiting grooves are provided at both ends of the sliding grooves. A first moving block and a second moving block are fixedly connected in the limiting grooves through a plurality of elastic members. A second card slot with the same relative position as the second moving block is formed in the lower surface of the inner window. A first card slot with the same relative position as the first moving block is formed in the lower surface of the outer window. In the initial state, the inner window and the outer window respectively exert pressure on the first moving block and the second moving block and transmit the pressure to the first blocking piece and the second blocking piece through the first connecting rod and the second connecting rod, so that the first blocking piece and the second blocking piece are received in the limiting grooves. When the outer window rotates and opens, the force applied to the second moving block disappears, and the second moving block moves upward under the thrust of the second elastic member and penetrates out of the limiting groove. The second blocking piece penetrates into the second card slot and abuts against the inner wall of the second card slot, so that the inner window cannot rotate, and vice versa, achieving the effect that the inner window and the outer window cannot be opened simultaneously, and reducing the pollution of the outside air to the clean room caused by the increase in the air flow rate due to the simultaneous opening of the inner and outer windows.

Specific embodiments
[0021] The following combines the drawings and embodiments to describe the present utility model in detail.
[0022] This fireproof transfer window includes a window frame 1. An inner window 2 and an outer window 3 are respectively rotatably connected to both ends of the window frame 1 in the length direction. The window frame 1, the inner window 2, and the outer window 3 are all made of stainless steel. Stainless steel has good flame retardancy and good corrosion resistance at high temperatures. Sealing strips are provided around the inner window 2 and the outer window 3 to enhance the sealing effect of the transfer window. When transferring items, the external user opens the outer window 3, puts the items to be transferred on the platform inside the window frame 1, then closes the outer window 3 and sends a signal to the internal personnel. The internal personnel open the inner window 2 to take out the objects on the platform.
[0023] There are two limiting grooves 4 formed on the bottom surface of Form 1. The two limiting grooves 4 are respectively located directly below the inner window 2 and the outer window 3. The two limiting grooves 4 are connected through two sliding grooves 13. A limiting device one and a limiting device two are respectively slidably connected to the inner walls of the two sliding grooves 13. The limiting device one abuts against the lower surface of the inner window 2, and the limiting device two abuts against the lower surface of the outer window 3. A first clamping groove 5 with the same relative position as the limiting device one is formed on the lower surface of the outer window 3, and the length of the first clamping groove 5 is the same as that of the limiting device one. A second clamping groove 6 with the same relative position as the limiting device two is formed on the lower surface of the inner window 2, and the length of the second clamping groove 6 is the same as that of the limiting device two. When the outer window 3 is rotated and opened on the inner wall of Form 1, the limiting device two penetrates out of the limiting groove 4 and enters the second clamping groove 6 and abuts against the upper surface of the second clamping groove 6, so that the inner window 2 cannot be rotated and opened outwards. On the contrary, when the inner window 2 is rotated and opened on the inner wall of Form 1, the limiting device one penetrates out of the limiting groove 4 and enters the first clamping groove 5 and abuts against the upper surface of the first clamping groove 5, so that the outer window 3 cannot be rotated and opened outwards. Thus, the effect that the inner window 2 and the outer window 3 cannot be opened simultaneously can be achieved.
[0024] The limiting device one includes a first connecting rod 7 and a first lifting assembly. The first lifting assembly is bonded to one end of the first connecting rod 7 close to the inner window 2. The first lifting assembly is slidably connected to the inner side wall of the limiting groove 4. The first lifting assembly abuts against the lower surface of the inner window 2. A first blocking piece 14 is bonded to one end of the first connecting rod 7 close to the outer window 3. When the inner window 2 rotates on the inner wall of Form 1, the pressure of the inner window 2 on the first lifting assembly disappears. The first lifting assembly located below the inner window 2 moves upwards in the limiting groove 4 and drives the first blocking piece 14 to move upwards in the limiting groove 4 through the first connecting rod 7. The first blocking piece 14 moves upwards and enters the first clamping groove 5 and abuts against the upper surface of the first clamping groove 5. The first blocking piece 14 is stuck with the first clamping groove 5, so that the outer window 3 cannot be rotated and opened outwards.
[0025] The limiting device two includes a second connecting rod 8 and a second lifting assembly. The second lifting assembly is bonded to one end of the second connecting rod 8 close to the outer window 3. The second lifting assembly is slidably connected to the inner side wall of the limiting groove 4. The second lifting assembly abuts against the lower surface of the outer window 3. A second blocking piece 15 is bonded to one end of the second connecting rod 8 close to the inner window 2. When the outer window 3 rotates on the inner wall of Form 1, the pressure of the outer window 3 on the second lifting assembly disappears. The second lifting assembly moves upwards in the limiting groove 4 and drives the second blocking piece 15 to move upwards in the limiting groove 4 through the second connecting rod 8. The second blocking piece 15 moves upwards and enters the second clamping groove 6 and abuts against the upper surface of the second clamping groove 6. The blocking piece is stuck with the second clamping groove 6, so that the inner window 2 cannot be rotated and opened outwards.
[0026] The first lifting component includes a first moving block 9 and two first elastic members 10. The first elastic members 10 are set as springs. One ends of the two first elastic members 10 are bonded to the lower surface of the moving block, and the other ends of the two first elastic members 10 are bonded to the bottom surface of the limiting groove 4. The first moving block 9 abuts against the lower surface of the inner window 2. In the initial state, the first elastic members 10 are completely in a compressed state under the pressure of the inner window 2 on the first moving block 9, and the blocking piece 14 is contracted in the limiting groove 4 through the first connecting rod 7. When the inner window 2 rotates and opens, the pressure on the first moving block 9 disappears. Due to its own elastic deformation performance, the first elastic members 10 rebound and generate an upward thrust on the first moving block 9. The first connecting rod 7 transmits the movement of the first moving block 9 to the blocking piece 14, and the blocking piece 14 penetrates out of the limiting groove 4 and enters the first clamping groove 5 and abuts against the inner wall of the first clamping groove 5, so that the outer window 3 cannot rotate outward.
[0027] The second lifting component includes a second moving block 11 and two second elastic members 12. The second elastic members 12 are set as springs. One ends of the two second elastic members 12 are bonded to the lower surface of the moving block, and the other ends of the two second elastic members 12 are bonded to the bottom surface of the limiting groove 4. The second moving block 11 abuts against the lower surface of the outer window 3. In the initial state, the second elastic members 12 are completely in a compressed state under the pressure of the outer window 3 on the second moving block 11, and the blocking piece 15 is contracted in the limiting groove 4 through the second connecting rod 8. When the outer window 3 rotates and opens, the pressure on the second moving block 11 disappears. Due to its own elastic deformation performance, the second elastic members 12 rebound and generate an upward thrust on the second moving block 11. The second connecting rod 8 transmits the movement of the second moving block 11 to the blocking piece 15, and the blocking piece 15 penetrates out of the limiting groove 4 and enters the second clamping groove 6 and abuts against the inner wall of the second clamping groove 6, so that the inner window 2 cannot rotate outward.
[0028] One sides of the first moving block 9 and the second moving block 11 away from the sliding groove 13 are both set as arcs. When the outer window 3 is closed during the process of putting an object into the window body 1, the side wall of the outer window 3 generates a thrust on the arc surface of the second moving block 11, causing the second moving block 11 to move downward and making the blocking piece 15 move through the second connecting rod 8 and be received in the limiting groove 4, so that the inner window 2 can rotate outward and open. On the contrary, during the process of closing the inner window 2 after using the inner window 2, the side wall of the inner window 2 generates a thrust on the arc surface of the first moving block 9, causing the first moving block 9 to move downward and making the blocking piece 14 move through the first connecting rod 7 and be received in the limiting groove 4, so that the outer window 3 can rotate outward and open. The length of the first moving block 9 is greater than the depth of the first clamping groove 5, and the length of the second moving block 11 is greater than the depth of the second clamping groove 6, which avoids the first moving block 9 and the second moving block 11 completely passing through the limiting groove 4 during the rising process and losing restraint, affecting the application of thrust on the second moving block 11 and the first moving block 9 when the outer window 3 or the inner window 2 is closed to enable them to move downward.
[0029] Working principle: For this fireproof transfer window, in the initial state, the pressures exerted by the outer window 3 and the inner window 2 on the second moving block 11 and the first moving block 9 respectively cause the first moving block 9 and the second moving block 11 to be received in the limiting groove 4. When an object needs to be transferred, the user opens the outer window 3 externally. The pressure of the outer window 3 on the second moving block 11 disappears, and the second moving block 11 moves upward under the thrust generated by the rebound of the second elastic member 12, driving the second blocking piece 15 to penetrate into the second clamping groove 6 and abut against the second clamping groove 6, making the inner window 2 unable to rotate. After the user places the item on the platform inside the window body 1, the user rotates and closes the outer window 3. During this process, the outer window 3 exerts pressure on the second moving block 11, causing it to move downward and driving the second blocking piece 15 to move downward and be received in the limiting groove 4 through the second connecting rod 8. Then, the internal staff opens the inner window 2. During the rotation process of opening the inner window 2, the pressure on the first moving block 9 disappears, and the first moving block 9 moves upward under the thrust generated by the rebound of the first elastic member 10, driving the first blocking piece 14 to penetrate into the first clamping groove 5 and abut against the first clamping groove 5, making the outer window 3 unable to rotate. After the staff takes out the object on the platform, the inner window 2 is rotated and closed. During this process, the inner window 2 exerts pressure on the first moving block 9, causing it to move downward and driving the first blocking piece 14 to move downward and be received in the limiting groove 4 through the first connecting rod 7, reducing the probability that the staff will open the inner window 2 and the outer window 3 simultaneously during use to accelerate the air flow rate, thereby causing pollution to the clean room by the outside air.

Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
