Description

Technical Field

[0001] This invention relates to the field of medical door sealing technology, and in particular to a medical door sealing mechanism. Background Technology

[0002] Medical door sealing mechanisms are a crucial component in ensuring air quality and preventing cross-infection within medical environments. They are designed to provide highly efficient sealing performance to prevent the intrusion of microorganisms such as dust, bacteria, and viruses, while maintaining the cleanliness and stability of the indoor environment. A typical medical door sealing mechanism involves installing a sealing strip at the bottom of the door, which adheres tightly to the floor to achieve a seal.

[0003] Patent document CN209742721U discloses a sealing mechanism for an automatic sliding door in medical applications. The mechanism includes a door frame, within which a fixed door leaf and a movable door leaf are located. The movable door leaf is fixed to the sliding mechanism via three door body brackets. Each door body bracket contains a rotating shaft, and one side of each bracket has a pressure-bearing wheel. Another side of the pressure-bearing wheel has a track fixed to the upper side frame of the door frame, with three grooves corresponding to the pressure-bearing wheel on the track. The rear edge of the movable door leaf is provided with a top frame sealing strip, a left side sealing strip, a right side sealing strip, and a bottom sealing strip. The inner sides of the upper and left side frames of the door frame are respectively fixed with a top decorative frame and a left decorative frame that cooperate with the top and left sealing strips. The left side of the fixed door leaf has a right decorative frame that cooperates with the right side sealing strip.

[0004] However, the above invention has the following shortcomings: A sealing strip is installed at the bottom of the door. The sealing strip is sealed by being in close contact with the ground. However, since the door is frequently opened and closed, and the sealing strip is always in close contact with the ground, the sealing strip will rub against the ground for a long time, which will shorten the service life of the sealing strip and affect the subsequent sealing effect. Summary of the Invention

[0005] The purpose of this invention is to provide a medical door sealing mechanism to solve the problems mentioned in the background art. This invention utilizes multiple sealing strips to press downwards when the door is closed, thereby reducing the service life of the surface sealing strips due to excessive friction.

In terms of economic value, this patent can reduce the friction between the sealing strip and the ground when the door rotates, extend the service life of the sealing strip, and save the economic and labor costs of replacing the sealing strip. In terms of social value, the downward movement of the main sealing strip and the secondary sealing strip in close contact with the ground improves the sealing effect of the door and enhances the ability to prevent the intrusion of dust, bacteria, viruses and other microorganisms. In terms of technical value, the downward movement of the main sealing strip and the secondary sealing strip in close contact with the ground forms a three-layer sealing protection, improving the sealing effect of the door.

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0027] This invention provides an improved medical door sealing mechanism. The technical solution of this invention is as follows:

[0028] like Figures 1 to 4 As shown, this embodiment of the invention provides a medical door sealing mechanism, including a mounting plate 1, a bottom groove 2 at the bottom end of the mounting plate 1, a movable plate 3 slidably installed inside the bottom groove 2, a main sealing strip 4 fixedly installed at the bottom end of the movable plate 3, and a sealing strip installed at the bottom of the door. The sealing strip is tightly attached to the ground to complete the sealing. It also includes an automatic lifting component 5 and an auxiliary sealing component 6. The operation of the two components saves costs and improves the working efficiency of the device.

[0029] Automatic lifting assembly 5 includes a movable groove 501 opened inside the mounting plate 1 to facilitate the movement of the longitudinal rod 504, improve the flexibility of the device, enhance the practicality and economy of the device through automatic lifting assembly 5, save costs, facilitate worker installation and later maintenance, and automatically achieve sealing when the door is closed.

[0030] The auxiliary sealing component 6 includes an L-shaped frame 601 that is slidably installed on both sides of the mounting plate 1. The L-shaped frame 601 serves as the base for subsequent installation, providing support for the installation of the sealing strip, which helps to improve the sealing performance, prevent the invasion of viruses and bacteria, and ensure medical safety.

[0031] Furthermore, a pair of longitudinal rod grooves 502 are provided at the bottom of the movable groove 501. A movable plate 503 is slidably installed inside the movable groove 501. A pair of longitudinal rods 504 are fixedly installed at the bottom of the movable plate 503. The longitudinal rods 504 slide with the longitudinal rod grooves 502. The bottoms of the pair of longitudinal rods 504 are fixedly connected to the movable plate 3. The sliding fit reduces friction, extends the service life of the main sealing strip 4, avoids frequent replacement of the sealing strip, wastes materials, improves economy, and enhances the sealing effect.

[0032] Furthermore, a pair of first springs 505 are fixedly connected between the movable plate 503 and the inner top wall of the movable groove 501, providing the movable plate 503 with vertical sliding space and improving the flexibility of the device.

[0033] Furthermore, one end of the mounting plate 1 is provided with an end groove 506, and a first pressure rod 507 is slidably installed inside the end groove 506. An end plate 508 is fixedly installed at the other end of the first pressure rod 507. The end of the first pressure rod 507 moves towards the inside of the movable groove 501, and the main sealing strip 4 is pushed downward by the connecting rod 509 and the first pressure rod 507 to stick tightly to the ground, thereby achieving a sealing effect.

[0034] As a further embodiment of the present invention, a connecting rod 509 is hinged between the movable plate 503 and the end plate 508, and a fixing plate 510 is fixedly installed near the end plate 508 in the movable groove 501. A pair of guide rods 511 are fixedly installed between the fixing plate 510 and the inner wall of the movable groove 501. The guide rods 511 slide with the end plate 508 to ensure the accuracy of the direction and further improve the stability and safety of the device.

[0035] Furthermore, a secondary sealing strip 602 is fixedly installed on one side of the L-shaped frame 601, and a pressure block 603 is fixedly installed on the top of the L-shaped frame 601. A pair of sliding grooves 604 are provided on both ends of the mounting plate 1. A pair of sliders 605 are fixedly installed on the side of the L-shaped frame 601 near the mounting plate 1. A second spring 606 is fixedly installed at the bottom of the sliders 605. The main sealing strip 4 and the secondary sealing strip 602 move downwards and fit tightly against the ground to form a three-layer sealing protection, thereby improving the sealing effect of the door.

[0036] Furthermore, a pair of transverse bar grooves 607 are provided in the middle of both sides of the mounting plate 1. The second pressure rod 609 is slidably installed in the transverse bar grooves 607, so that the device is subjected to uniform force, improves the safety and stability of the device, and maintains the integrity of the device.

[0037] Furthermore, a pair of guide blocks 610 are fixedly installed on both sides of the second pressure rod 609. Each transverse rod groove 607 has a guide groove 608 inside. The guide block 610 is slidably connected to the guide groove 608. A pressing block 611 is fixedly installed at one end of the second pressure rod 609. The pressing block 611 is used to prevent the material from shaking, maintain the material shape, and press the sealing strip downward to improve the sealing performance.

[0038] Specific working method: During installation, the mounting plate 1 is fixedly installed at the bottom of the door. When the door is closed, because one end of the first pressure rod 507 is hemispherical, the end of the first pressure rod 507 is subjected to pressure from the other side of the door or door frame, causing the first pressure rod 507 to move towards the inside of the movable groove 501. Then, through the connecting rod 509, the movable plate 503 is pushed downward, causing the main sealing strip 4 to move downward and press tightly against the ground, thereby achieving a sealing effect. Furthermore, during the closing process, the main sealing strip 4 moves downward, reducing the pressure on the main sealing strip. 4. Reduced friction time with the ground avoids frequent replacement of sealing strips and extends their service life. When the moving plate 3 moves downward, the arc surfaces on both sides of the moving plate 3 exert pressure on the end of the second pressure rod 609, pushing the second pressure rod 609 outward. Then, the squeezing block 611 exerts downward pressure on the pressure block 603, pushing the secondary sealing strip 602 downward, so that the two secondary sealing strips 602 are in close contact with the ground, thus forming a three-layer sealing protection, effectively preventing the invasion of bacteria and viruses and improving the sealing effect.

[0039] The foregoing description enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
