Description

Technical Field

[0001] This invention relates to the field of protective door technology, specifically to a sealing structure for the edge seams of a medical protective door. Background Technology

[0002] To achieve a sterile environment, isolate unauthorized personnel, and ensure the confidentiality of operations, protective doors are usually installed in hospitals or operating workshops. With the advancement of electric technology, these protective doors have been upgraded to electric drives, with the opening and closing of the protective doors driven by a motor.

[0003] When a protective door is closed, it usually needs to be sealed. For side-opening protective doors, sealing in the direction of movement is easy to achieve. By setting a sealing element and using the movement of the protective door to squeeze, the side of the protective door can be squeezed and contacted with the sealing element to achieve the purpose of sealing. However, the difficulty in sealing the protective door lies in sealing the seams on the top and bottom sides. In order to maintain the smoothness of opening and closing, guide rails are usually set on the top and bottom sides, and rollers are used for rolling. However, the top and bottom sides lack driving force for sealing and pressing, resulting in lower sealing performance and greater sealing difficulty.

[0004] The difficulty in sealing lies in the fact that the gap between the roller and the guide rail is hard to fill. The extension and retraction of the roller will expose the gap, making it easier to fill. However, when the roller retracts, it will cause the entire protective door to rise and fall, affecting the connection between the protective door and the opening and closing drive structure. If the roller does not extend or retract, the gap is difficult to seal. Even if it is sealed, it will still affect the movement of the roller when the protective door opens and closes. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing structure for the edge seams of a medical protective door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0013] Preferably, the driving device includes an adjusting screw, the telescopic groove is provided with a screw hole penetrating the inner wall, the adjusting screw is threaded into the screw hole, and the end bearing of the adjusting screw is rotatably connected to one end of the second locking block.

[0014] Preferably, the protective door is provided with a storage groove, in which a telescopic rod is provided. The telescopic end of the telescopic rod is connected to a rotating frame, and a roller is rotatably mounted on the rotating frame. The roller is located between a pair of adjacent side rails. An annular groove is provided on the outer side of the port of the storage groove, and a pair of coaxially sleeved annular airbags are provided in the annular groove. The inflatable airbags in the hollow cavities on both sides of the flexible sealing strip are connected to a pair of annular airbags through an interface located on the sealing plate and a flexible air tube, respectively.

[0015] Preferably, the linkage component includes a lifting element, a second spring, and a hinge. The protective door is provided with a lifting groove inside. The lifting groove is located between the boss and the annular groove. The outside of the lifting groove is sealed by a removable sealing plate.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 7 The present invention provides a technical solution:

[0030] Example 1: A sealing structure for the edge seam of a medical protective door includes a boss 11, which is set on the two side walls of the protective door 1. The protective door 1 slides in the wall driven by a motor. The wall includes an inner wall 2 and an outer wall 3. A sliding groove 4 is provided between the inner wall 2 and the outer wall 3. The protective door 1 slides along the sliding groove 4. Tracks 7 are provided at both the upper and lower ends of the sliding groove 4. Retractable rollers 8 are provided at both the upper and lower ends of the protective door 1. The rollers 8 slide along the tracks 7.

[0031] The protective door 1 is driven by an electric device to open and close laterally within the wall. The lateral opening and closing motion is limited by the cooperation of the track 7 and the roller 8. The driving technology of the protective door 1 is a common technology in the field, such as motor drive, hydraulic or pneumatic telescopic drive, etc.

[0032] A plug-in component is elastically inserted through the boss 11. The inner wall 2 and the outer wall 3 are provided with slots 10 that cooperate with the boss 11 for plugging in. The inner wall 2 and the outer wall 3 are respectively provided with telescopic grooves 9 and slots 18. The telescopic groove 9 is provided with a drive device that drives the plug-in component to plug into the slot 18.

[0033] During the lateral advancement process, the boss 11 is inserted into the slot 10 to limit the height between the protective door 1 and the wall. After the roller 8 retracts, the boss 11 and the slot 10 work together to support the height of the protective door 1, preventing the protective door 1 from falling down and causing the connection with the electric device to detach.

[0034] Then, the drive device is used to drive the plug-in component to move, so that the plug-in component is plugged into the wall, thereby limiting and locking the protective door 1 and ensuring the position of the protective door 1 in the direction of movement.

[0035] The upper and lower ends of the protective door 1 are fixedly installed with sealing plates 31 located on both sides of the roller 8. A flexible sealing strip 39 is provided on the sealing plate 31. The flexible sealing strip 39 is concave in the middle and hollow on both sides. An inflatable airbag 32 is provided in the hollow cavity. A pair of side rails 33 are provided on the track 7. A sealing groove 35 is provided on the side rail 33 to cooperate with the flexible sealing strip 39. A gap is left between the outer wall of the flexible sealing strip 39 and the inner wall of the sealing groove 35. The protective door 1 is provided with a linkage component that causes the inflatable airbag 32 to expand through the insertion movement of the insertion component.

[0036] During the insertion process, the linkage component drives the insertion component to allow air to enter the expansion airbag 32, thereby increasing its volume and driving the hollow sidewalls on both sides of the flexible sealing strip 39 to expand outward. In the process of expansion, it achieves a tight fit with the sealing groove 35, thus achieving a seal.

[0037] Working principle: First, the electric device drives the protective door 1 to close laterally. Due to the gap between the flexible sealing strip 39 and the sealing groove 35, the roller 8 on the protective door 1 can move laterally smoothly, so that the free end of the protective door 1 is inserted into the sliding groove 4. During the insertion process, the boss 11 is inserted into the slot 10 to limit the height between the protective door 1 and the wall. After the roller 8 retracts, the boss 11 and the slot 10 cooperate to support the height of the protective door 1, preventing the protective door 1 from falling down and causing the connection with the electric device to detach.

[0038] As the connection continues, the outer walls on both sides of the protective door 1 in the direction of movement come into contact with the seals on the wall. Under the action of the driving force, the door remains sealed and pressed together (this technology is a common sealing method in the field and will not be described in detail). The drive device drives the insertion component to move, so that the insertion component is inserted into the wall, thereby limiting and locking the protective door 1, ensuring the position of the protective door 1 in the direction of movement, and maintaining the sealed state.

[0039] As the plug-in assembly moves, it causes the inflatable airbag 32 to take in air, thereby increasing its volume. This drives the hollow sidewalls on both sides of the flexible sealing strip 39 to expand outward, filling the gap between the flexible sealing strip 39 and the sealing groove 35. As a result, during the expansion process, it achieves a tight fit with the sealing groove 35, thus achieving a seal.

[0040] Example 2: Based on Example 1, in order to improve the sealing effect, a protrusion is provided on the side rail 33 that is pressed into the middle recess of the flexible sealing strip 39. A long groove is provided through the protrusion, and a rubber support block 34 is provided in the long groove. The rubber support block 34 is provided with multiple sets of through grooves along the longitudinal direction of the support. A pair of elastic arc nets 36 distributed in a circular array are provided on the hollow side walls on both sides of the flexible sealing strip 39. The outer arc wall of the inflatable airbag 32 is attached to the elastic arc nets 36.

[0041] The elastic arc mesh 36 is designed to accommodate the volume expansion of the inflatable airbag 32, facilitating the expansion of the hollow sidewalls on both sides of the flexible sealing strip 39. It also allows for timely repositioning during pressure relief. The rubber support block 34 with a vertical through-groove provides stable vertical support, while the presence of numerous gaps in the transverse direction allows for easy lateral compression of the rubber support block 34 as the hollow sidewalls of the flexible sealing strip 39 expand. This facilitates sealing by the relative compression of the hollow cavities on both sides, preventing expansion to the other side and avoiding separation between the flexible sealing strip 39 and the sealing groove 35 due to expansion.

[0042] Example 3: Based on Example 2, the plug-in assembly includes a pressure rod 14, a first locking block 15, and a second locking block 16. The bosses 11 on both sides of the protective door 1 are respectively provided with a first inner groove 12 and a second inner groove 20. The first inner groove 12 can correspond to the locking groove 18, and the second inner groove 20 can correspond to the telescopic groove 9. The first inner groove 12 and the second inner groove 20 are connected by a through hole 13. The pressure rod 14 slides through the through hole 13, and a first locking block 15 is provided at one end of the pressure rod 14 extending to the first inner groove 12. An end plate 41 is provided at the other end of the pressure rod 14. A second locking block 16 driven by a driving device is provided in the telescopic groove 9. The second locking block 16 is pressed onto the end plate 41.

[0043] By setting up a transverse sliding member consisting of a pressure rod 14, a first locking block 15, and a second locking block 16, the protective door 1 is fixed to the wall under the action of the driving device, which achieves the purpose of limiting the height of the protective door 1 and fixing the lateral position of the protective door 1.

[0044] The inner diameter of the through hole 13 is smaller than the inner diameter of the first inner groove 12 and the second inner groove 20. A first spring 17 is sleeved on the pressure rod 14. One end of the first spring 17 abuts against the end plate 41, and the other end of the first spring 17 abuts against the inner wall of the end of the second inner groove 20. The first locking block 15 can be inserted into the locking groove 18 along the first inner groove 12. The second locking block 16 can extend into the second inner groove 20 along the telescopic groove 9. The first locking block 15 is located between the locking groove 18 and the first inner groove 12 on the outer wall 3, and the second locking block 16 is located between the telescopic groove 9 and the second inner groove 20. A reinforcing ring 42 is provided on the first locking block 15, which is directly opposite the gap between the locking groove 18 and the first inner groove 12.

[0045] The first spring 17 is used to achieve elastic installation of the plug-in assembly, which facilitates automatic reset. The first locking block 15 is used to connect the boss 11 to the outer wall 3, and the second locking block 16 is used to connect the boss 11 to the inner wall 2. By limiting the positions of the first locking block 15 and the second locking block 16, the strength of the connection is improved.

[0046] The drive device includes an adjusting screw 6, and a screw hole 5 through the inner wall 2 is provided on the telescopic groove 9. The adjusting screw 6 is threaded into the screw hole 5, and the end bearing of the adjusting screw 6 is rotatably connected to one end of the second locking block 16.

[0047] When the protective door 1 is closed to the side, the personnel on the inner wall 2 can squeeze the second locking block 16 by rotating the adjusting screw 6. As the second locking block 16 is squeezed and slid, the first spring 17 is compressed and the pressure rod 14 slides, so that the first locking block 15 extends into the slot 18 to achieve the purpose of lateral insertion and fixation.

[0048] Example 4: Based on Example 3, the protective door 1 is provided with a storage groove 26, and a telescopic rod 27 is provided in the storage groove 26. The telescopic end of the telescopic rod 27 is connected to a rotating frame 37. A roller 8 is rotatably installed on the rotating frame 37. The roller 8 is located between a pair of adjacent side rails 33. A circular annular groove 29 is provided on the outer side of the port of the storage groove 26. A pair of coaxially sleeved annular airbags 30 are provided in the annular groove 29. The inflatable airbags 32 in the hollow inner cavity on both sides of the flexible sealing strip 39 are connected to a pair of annular airbags 30 through the interface 38 located on the sealing plate 31 and the flexible air pipe respectively.

[0049] By setting the telescopic rod 27, the roller 8 can be completely stored in the storage groove 26, realizing the telescopic installation of the roller 8. By setting the annular airbag 30, the inflatable airbag 32 can be supplied with air.

[0050] The linkage assembly includes a lifting component, a second spring 25, and a hinge 22. The protective door 1 has a lifting groove 19 inside, which is located between the boss 11 and the annular groove 29. The outer side of the lifting groove 19 is sealed by a removable sealing plate. The lower end of the lifting groove 19 is connected to the annular groove 29 through a vertical groove 28. The lifting component includes a pull rod 24 that slides up and down along the vertical groove 28 and traction plates 23 located at both ends of the pull rod 24. The traction plates 23 at the lower end of the pull rod 24 are pressed onto a pair of annular airbags 30. The traction plates 23 at the upper end of the pull rod 24 are located in the lifting groove 19 and are connected to the end plate 41 through the hinge 22. Multiple sets of guide wheels 21 are rotatably arranged between the lifting groove 19 and the second inner groove 20 to facilitate the smooth bending and extension of the hinge 22.

[0051] By sliding the pressure rod 14, the hinge 22 on the end plate 41 pulls the lifting component to rise, which in turn causes the traction plate 23 at the lower end of the lifting component to squeeze the annular airbag 30. The airflow in the annular airbag 30 moves towards the inflatable airbag 32, which increases the internal pressure of the inflatable airbag 32 and causes it to expand in volume, forming a compression with the inner wall of the sealing groove 35.

[0052] The guide wheel 21 is configured as a gear, and the hinge 22 can mesh with the gear. A second spring 25 is sleeved on the hinge 22, and the second spring 25 is pressed between the upper end traction plate 23 of the pull rod 24 and the upper end inner wall of the lifting groove 19.

[0053] To ensure the stability of the linkage, the hinge 22 is configured to mesh with the gear for steering, avoiding the influence of deformation caused by traditional traction materials such as ropes on the linkage motion. At the same time, the second spring 25 is used to keep the lifting component moving downward initially, causing the lower traction plate 23 to drive the annular airbag 30 to expand downward, increasing its volume and drawing the airflow from the inflatable airbag 32 into the annular airbag 30, keeping the annular airbag 30 contracted. This leaves a gap between the flexible sealing strip 39 and the sealing groove 35, and under the traction of the hinge 22, the annular airbag 30 is squeezed. When it is necessary to open the protective door 1, the second spring 25's return force facilitates the quick release of the seal.
