Description

Technical Field

[0001] This utility model relates to the field of steel medical door technology, and more specifically, to an integrated steel medical door. Background Technology

[0002] In existing technologies, integrated steel medical doors serve as crucial isolation and protection facilities in medical and health settings such as hospital operating rooms, intensive care units, infectious disease isolation areas, sterile preparation rooms, and laboratory biosafety cabinets. They are widely used in medical buildings for effective isolation and control of clean areas from the external environment. Some existing medical door devices utilize inflatable airbags installed on the door edge or inside the door frame to achieve a seal when the door and frame are closed. Compressed air is injected into the airbags, causing them to expand and deform, tightly fitting against the gap between the door and frame, thereby blocking external airflow. Dust, bacteria, and other contaminants can penetrate into clean areas, necessitating the airtightness and cleanliness requirements of medical facilities. However, existing airbag sealing structures require inflation or deflation of the airbag depending on the door's opening and closing status. Existing exhaust devices typically employ a fixed open state, failing to allow for flexible opening and closing control based on the door's actual needs. This results in the airbag slowly deflating even when not in use, affecting the sealing effect and impacting the actual performance of the medical door airbag sealing system.

[0003] Secondly, while some improved integrated steel medical doors achieve flexible opening and closing of the airbag exhaust device by adding certain components, allowing the exhaust device to operate according to the door's open or closed state, the control structure design of these doors is relatively simple, lacking in mechanical connection stability and locking reliability. This makes them susceptible to external forces such as repeated impacts and vibrations from frequent door opening and closing, uneven forces applied by medical staff pushing and pulling the door, and accidental impacts from medical equipment carts colliding with the door. These factors can cause the originally adjusted and fixed exhaust control structure to experience unexpected loosening and dislocation of connecting parts, and control mechanism malfunctions. Problems such as structural failure, malfunctioning switches, or even accidental opening or failure to close the exhaust channel can cause the adjusted exhaust control structure to shift and become displaced, failing to maintain its original working state. Consequently, when the door needs to be closed and sealed, the airbag may fail to maintain its inflated state due to the accidental opening of the exhaust device, resulting in a significant decrease in the sealing effect. This not only causes the loss of airtightness between the clean area and the external environment, allowing external polluted air, pathogens, and harmful gases to enter the room and affect the quality of the medical environment, but may also lead to inaccurate positive or negative pressure control in the room due to sealing failure, resulting in cross-infection risks or dangerous gas leaks and other safety hazards.

[0009] The present invention is further configured such that a roller is rotatably mounted on one side of the locking block, and the roller is engaged between two adjacent positioning blocks.

[0010] The present invention is further configured such that a return spring is movably sleeved on the outside of the pressure relief tube, and one end of the return spring is connected to the positioning sleeve.

[0012] The present invention is further provided with a plurality of anti-slip strips fixedly provided on the outer side of the control sleeve.

[0014] The present invention is further configured such that a thrust bearing is detachably provided on one side of the motion plate, and the other end of the return spring is connected to the thrust bearing.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an integrated steel medical door, which has the following beneficial effects:

[0017] 1. Through the linkage design of the control sleeve and the adjustment sleeve, and the sliding adjustment of the sealing plate on the control rod, the sealing control and opening and closing state switching after the airbag is inflated can be realized. When the door is closed, the gas pressure pushes the sealing plate to open the exhaust channel to complete the automatic pressure relief. After the pressure relief is completed, the movable spring pushes the sealing plate to reset and close the channel, forming a pressure response mechanism. This structure effectively avoids the passive pressure relief problem of traditional fixed exhaust devices and maintains the continuous stability of the airtightness of the clean area.

[0018] 2. A multi-point locking structure of locking blocks and rollers, combined with the guiding constraint of the slide rail limiting groove, forms a double locking protection mechanism. When the door is frequently opened and closed or subjected to external impact, the positioning sleeve restricts the displacement of the control sleeve through the rigid support of the horizontal plate and the vertical plate. Then, the inner wall of the control sleeve limits the outer wall of the roller. At the same time, the elastic reset of the moving spring and the return spring can ensure that the control sleeve is in the preset locking position to the greatest extent. This composite structure of rigid limiting and elastic compensation enhances the impact resistance of the exhaust control system, prevents malfunctions caused by vibration or collision, and ensures long-term reliable locking of the sealing plate under complex working conditions.

A three-way pipe 3 is connected to one side of the airbag 2. Delivery pipes 4 are connected to both sides of the three-way pipe 3. A control sleeve 5 and a pressure relief pipe 6 are mounted on one side of the delivery pipes 4. The two ends of the control sleeve 5 are rotatably connected to the delivery pipes 4 and pressure relief pipes 6, respectively.

A configuration groove 17 and an adapter groove 18 are opened on the side wall of the adjusting rod 15. An adjusting sleeve 19 is movably provided inside the control sleeve 5. Multiple configuration holes 20 are opened at one end of the pressure relief pipe 6. A sealing plate 21 is slidably provided inside the conveying pipe 4. A movable spring 22 is movably sleeved on the outside of the adjusting rod 15. One end of the movable spring 22 is connected to the sealing plate 21, and the other end of the movable spring 22 abuts against one side of the adjusting sleeve 19.

[0029] The door body 1 is provided with an observation window 23, and a door frame 24 is provided on one side of the door body 1. The door body 1 is rotatably connected to one side of the door frame 24.

[0030] In this embodiment, when the device is needed, the moving plate 7 is first rotated forward. The moving plate 7 drives the moving groove 8 and the thrust bearing 32 to rotate forward. When the moving groove 8 rotates to the position corresponding to the horizontal plate 11, it pushes the positioning sleeve 9, causing the positioning sleeve 9 to drive one side of the vertical plate 10 and the horizontal plate 11 to gradually slide into the moving groove 8. At the same time, the positioning sleeve 9 and the thrust bearing 32 cooperate to compress the return spring 26. When the return spring 26 is compressed to its limit, the horizontal plate 11 closest to the positioning sleeve 9 just passes through the moving groove 8 and moves to the other side of the moving plate 7. Then, the moving plate 7 is rotated in the opposite direction, causing the moving plate 7 to drive the moving groove 8 and the thrust bearing 32 to rotate in the opposite direction and reset, thereby causing the moving groove 8 to rotate and reset to a position where it is not in contact with the vertical plate 10 and the horizontal plate 11. At the position corresponding to the flat plate 11, the vertical plate 10 and the horizontal plate 11 closest to the positioning sleeve 9 cooperate to limit the positioning sleeve 9 to one side of the moving plate 7, so that the positioning sleeve 9 no longer limits the outer wall of the roller 25. Then, the control sleeve 5 is rotated in the forward direction, which will drive the slide rail 28 on one side to rotate in the forward direction, so that the slide rail 28 drives the locking block 12 and the roller 25 to move through the limiting groove 27, thereby causing the roller 25 to slide out between the two adjacent positioning blocks 14. The roller 25 will drive the locking block 12 on one side to slide outward along the slide rail 28 and the limiting groove 27. At the same time, the locking block 12 will cooperate to stretch the moving spring 13 outward. Meanwhile, the control sleeve 5 will drive the inner adjusting block 30 to rotate, and then the adjusting block 30 will cooperate with the adjusting groove 31 to adjust the... The adjusting sleeve 19 rotates forward, and moves along the threaded section on the inner wall of the pressure relief pipe 6, lengthening the distance between the sealing plate 21 and the adjusting sleeve 19. This causes the movable spring 22 to gradually reset, unlocking the sealing plate 21. Then, the controlling sleeve 5 continues to rotate, allowing the sealing plate 21 to open directly. The external device then connects to the output end of the pressure relief pipe 6 and slowly inflates the airbag 2. After inflation, the controlling sleeve 5 rotates in the reverse direction, causing the sealing plate 21 to re-seal the delivery pipe 4. The controlling sleeve 5, in conjunction with the sealing plate 21, then compresses the movable spring 22 to a certain extent. The rotation of the controlling sleeve 5 stops, and the sealing door closes. The sealing door, in conjunction with the door frame 24, compresses the airbag 2, causing the gas inside the airbag 2 to flow along the three... The gas enters the delivery pipe 4 through the pipe 3, and then the gas pushes the sealing plate 21, thereby pushing the sealing plate 21 open, so that the sealing plate 21 slides along the control rod 15, and the distance between the sealing plate 21 and the adjustment sleeve 19 will shorten, so that the sealing plate 21 and the adjustment sleeve 19 cooperate to gradually squeeze the movable spring 22. At this time, the sealing plate 21 is on the other side of the configuration groove 17. Then the compressed gas enters the flow groove 16 opened inside the control rod 15 through the configuration groove 17, and then the gas enters the other side of the adjustment sleeve 19 through the adaptation groove 18 opened on the side wall of the control rod 15. Then the gas will be discharged to the outside through the configuration hole 20. When the sealing airbag 2 fits with the gap, the movable spring 22 resets and pushes the sealing plate 21, so that the sealing plate 21 moves and resets, achieving resealing.

[0031] Please see Figures 3-5 As a further implementation of the overall equipment: a roller 25 is rotatably installed on one side of the locking block 12, and the roller 25 is engaged between two adjacent positioning blocks 14.

[0032] A return spring 26 is movably sleeved on the outside of the pressure relief pipe 6, and one end of the return spring 26 is connected to the positioning sleeve 9.

[0033] The locking block 12 has a limiting groove 27, and multiple slide rails 28 are fixedly provided on one side of the control sleeve 5. The locking block 12 is slidably installed on the outside of the slide rails 28 through the limiting groove 27.

[0034] Multiple anti-slip strips 29 are fixedly provided on the outer side of the control sleeve 5.

[0035] An adjustment block 30 is fixedly provided on the inner side of the control sleeve 5, and an adjustment groove 31 is provided on the outer side of the adjustment sleeve 19. The adjustment block 30 slides in the adjustment groove 31.

[0036] A thrust bearing 32 is detachably mounted on one side of the motion plate 7, and the other end of the return spring 26 is connected to the thrust bearing 32.

[0037] More specifically, after the venting is complete and the sealing plate 21 is resealed, the control sleeve 5 is rotated in the reverse direction. The control sleeve 5 will cause one side of the slide rail 28 to reverse, so that the slide rail 28 drives the locking block 12 and the roller 25 to rotate in the opposite direction through the limiting groove 27. This causes the roller 25 to slide out between the two corresponding positioning blocks 14, and the roller 25 will drive one side of the locking block 12 to slide outward along the slide rail 28 and the limiting groove 27. At the same time, the locking block 12 will cooperate to stretch the moving spring 13 outward. Meanwhile, the control sleeve 5 will drive the inner adjusting block 30 to rotate, and then through the cooperation of the adjusting block 30 and the adjusting groove 31, the adjusting sleeve will rotate. 19 rotates in the opposite direction, and the adjusting sleeve 19 moves along the threaded section on the inner wall of the pressure relief pipe 6, causing the sealing plate 21 and the adjusting sleeve 19 to press against the movable spring 22, thus compressing the movable spring 22. When the movable spring 22 is compressed, the sealing plate 21 cannot open, and then the rotation of the control sleeve 5 stops. At this time, the control sleeve 5 drives the roller 25 and the locking block 12 to rotate between the two original positioning blocks 14 through the cooperation of the slide rail 28 and the limiting groove 27. Then the moving spring 13 resets and pulls the locking block 12, causing the locking block 12 to drive the limiting groove 27 to slide inward along the slide rail 28, thereby causing the locking block 12 to drive a... The side roller 25 engages between the two original positioning blocks 14, and then the moving plate 7 rotates forward again, causing the moving plate 7 to drive the moving groove 8 and the thrust bearing 32 to rotate forward again. When the moving groove 8 rotates to the position corresponding to the horizontal plate 11, the return spring 26 pushes the positioning sleeve 9 to slide back to its original position. Then, the positioning sleeve 9 drives the vertical plate 10 on one side and the three horizontal plates 11 to slide back to their original positions. When the return spring 26 is fully reset, the other two horizontal plates 11 have just moved back to their original positions on both sides of the moving plate 7. Then, the moving plate 7 rotates in the opposite direction again, causing the moving plate 7 to drive the moving groove 8 and the thrust bearing 32 on one side to rotate forward again. The bearing 32 rotates in the opposite direction to reset, thereby causing the moving groove 8 to rotate in reverse and reset to a position that does not correspond to the vertical plate 10 and the horizontal plate 11. Then, the vertical plate 10, in conjunction with the two corresponding horizontal plates 11, supports the positioning sleeve 9 to one side of the moving plate 7, making it impossible for the positioning sleeve 9 to slide easily. Then, the inner wall of the positioning sleeve 9 re-limits the outer wall of the roller 25, preventing the roller 25 and the locking block 12 from moving outward. Thus, through the cooperation with the positioning block 14, and the cooperation with the slide rail 28 and the limiting groove 27, the control sleeve 5 cannot rotate accidentally, thereby ensuring the stable locking of the sealing plate 21 in the exhaust device and preventing it from opening accidentally.

[0038] In summary, during the use or operation of the entire equipment: When the equipment needs to be used, first rotate the moving plate 7 clockwise. The moving plate 7 will drive the moving groove 8 and the thrust bearing 32 to rotate clockwise. When the moving groove 8 just rotates to the position corresponding to the horizontal plate 11, it pushes the positioning sleeve 9, causing the positioning sleeve 9 to drive one side of the vertical plate 10 and the horizontal plate 11 to gradually slide into the moving groove 8. At the same time, the positioning sleeve 9 and the thrust bearing 32 will cooperate to compress the return spring 26. When the return spring 26 is compressed to its limit, the horizontal plate 11 closest to the positioning sleeve 9 just passes through the moving groove 8 and moves to the other side of the moving plate 7. Then, rotate the moving plate 7 in the reverse direction, causing the moving plate 7 to drive the moving groove 8 and the thrust bearing 32 to rotate in the opposite direction and reset, thereby causing the moving groove 8 to rotate and reset to a position where it is not aligned with the vertical plate 11. At the corresponding positions of the vertical plate 10 and the horizontal plate 11, the vertical plate 10 and the horizontal plate 11 closest to the positioning sleeve 9 cooperate to limit the positioning sleeve 9 to one side of the moving plate 7, so that the positioning sleeve 9 no longer limits the outer wall of the roller 25. Then, the control sleeve 5 is rotated in the forward direction, which will drive the slide rail 28 on one side to rotate in the forward direction, so that the slide rail 28 drives the locking block 12 and the roller 25 to move through the limiting groove 27, thereby causing the roller 25 to slide out between the two adjacent positioning blocks 14. The roller 25 will drive the locking block 12 on one side to slide outward along the slide rail 28 and the limiting groove 27. At the same time, the locking block 12 will cooperate to stretch the moving spring 13 outward. Meanwhile, the control sleeve 5 will drive the inner adjusting block 30 to rotate, and then through the cooperation of the adjusting block 30 and the adjusting groove 31 The adjusting sleeve 19 is rotated in the forward direction and moves along the threaded surface of the pressure relief pipe 6, increasing the distance between the sealing plate 21 and the adjusting sleeve 19. This causes the movable spring 22 to gradually reset, unlocking the sealing plate 21. Then, the control sleeve 5 is rotated to open the sealing plate 21 directly, allowing the external device to slowly inflate the airbag 2 via the connection between the output end and the pressure relief pipe 6. After inflation, the control sleeve 5 is rotated in the reverse direction, causing the sealing plate 21 to re-seal the delivery pipe 4. The control sleeve 5, in conjunction with the sealing plate 21, then compresses the movable spring 22 to a certain extent. The rotation of the control sleeve 5 is then stopped, and the sealing door is closed. The sealing door, in conjunction with the door frame 24, compresses the airbag 2, causing the gas inside the airbag 2 to... The gas enters the delivery pipe 4 through the three-way pipe 3, and then pushes the sealing plate 21, thereby pushing the sealing plate 21 open, so that the sealing plate 21 slides along the control rod 15, and the distance between the sealing plate 21 and the adjustment sleeve 19 will shorten, so that the sealing plate 21 and the adjustment sleeve 19 cooperate to gradually squeeze the movable spring 22. At this time, the sealing plate 21 is on the other side of the configuration groove 17. Then the compressed gas enters the flow groove 16 opened inside the control rod 15 through the configuration groove 17, and then the gas enters the other side of the adjustment sleeve 19 through the adaptation groove 18 opened on the side wall of the control rod 15. Then the gas will be discharged to the outside through the configuration hole 20. When the sealing airbag 2 fits with the gap, the movable spring 22 resets and pushes the sealing plate 21, so that the sealing plate 21 moves and resets, achieving resealing.

[0039] After the venting is complete and the sealing plate 21 is resealed, the control sleeve 5 is rotated in the reverse direction. The control sleeve 5 will cause one side of the slide rail 28 to reverse, so that the slide rail 28 drives the locking block 12 and the roller 25 to rotate in the opposite direction through the limiting groove 27. This causes the roller 25 to slide out between the two corresponding positioning blocks 14, and the roller 25 will drive one side of the locking block 12 to slide outward along the slide rail 28 and the limiting groove 27. At the same time, the locking block 12 will cooperate to stretch the moving spring 13 outward. Meanwhile, the control sleeve 5 will drive the inner adjusting block 30 to rotate, and then through the cooperation of the adjusting block 30 and the adjusting groove 31, the adjusting sleeve 19 will move inward. The control sleeve 5 rotates in the opposite direction, and the adjusting sleeve 19 moves along the threaded section on the inner wall of the pressure relief pipe 6. This causes the sealing plate 21 and the adjusting sleeve 19 to press against the movable spring 22, compressing the movable spring 22. Once the movable spring 22 is compressed, the sealing plate 21 cannot open, and the control sleeve 5 stops rotating. At this time, the control sleeve 5, through the cooperation of the slide rail 28 and the limiting groove 27, drives the roller 25 and the locking block 12 to rotate between the two original positioning blocks 14. Then, the moving spring 13 resets and pulls the locking block 12, causing the locking block 12 to drive the limiting groove 27 to slide inward along the slide rail 28, thereby causing the locking block 12 to drive one side of the roller. Wheel 25 engages between the two original positioning blocks 14, and then the moving plate 7 rotates forward again, causing the moving plate 7 to drive the moving groove 8 and the thrust bearing 32 to rotate forward again. When the moving groove 8 rotates to the position corresponding to the horizontal plate 11, the return spring 26 pushes the positioning sleeve 9 to slide back to its original position. Then, the positioning sleeve 9 drives the vertical plate 10 on one side and the three horizontal plates 11 to slide back to their original positions. When the return spring 26 is fully reset, the other two horizontal plates 11 have just moved back to their original positions on both sides of the moving plate 7. Then, the moving plate 7 rotates in the opposite direction again, causing the moving plate 7 to drive the moving groove 8 and the thrust bearing 32 on one side to rotate forward again. The bearing 32 rotates in the opposite direction to reset, thereby causing the moving groove 8 to rotate in reverse and reset to a position that does not correspond to the vertical plate 10 and the horizontal plate 11. Then, the vertical plate 10, in conjunction with the two corresponding horizontal plates 11, supports the positioning sleeve 9 to one side of the moving plate 7, making the positioning sleeve 9 unable to slide easily. Then, the inner wall of the positioning sleeve 9 re-limits the outer wall of the roller 25, making the roller 25 and the locking block 12 unable to move outward. Thus, through the cooperation with the positioning block 14, and the cooperation with the slide rail 28 and the limiting groove 27, the control sleeve 5 cannot rotate accidentally, thereby ensuring the stable locking of the sealing plate 21 in the exhaust device and preventing it from opening accidentally.
