Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building materials, in particular to a clean airtight ward door suitable for infection wards. Background Art
[0002] Hospital wards are used to treat patients in need, so that hospitals can treat and monitor patients in a timely manner. Ordinary wards can treat some ordinary patients whose symptoms are not contagious and have certain immunity. The air in the ward can circulate freely with the outside world. Infection wards are mainly used to treat some infectious patients. The air pressure in infection wards is required to be lower than the outdoor air pressure, so that pathogenic microorganisms will not leak out due to air convection caused by pressure difference, and the outdoor area will not be polluted. The polluted air in the ward can be discharged to the outside atmosphere after effective filtration and disinfection.
[0003] The existing ward door seals are just ordinary anti-collision rubber strips, which have no sealing effect, and there is a gap between the bottom edge of the door leaf and the ground after closing, which cannot meet the airtightness requirements of the infection ward. Utility Model Content
[0004] In order to make up for the deficiencies in the prior art, the utility model provides a clean airtight ward door suitable for infection wards. After the door leaf is closed, it can achieve a tight fit and airtight effect, meeting the use requirements of infection wards.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A clean airtight ward door suitable for an infection ward comprises a hinged door frame and a door leaf, each side of the door frame is provided with a sealing strip that fits the door leaf, a sinking sealing mechanism is provided at the bottom of the door leaf, the sinking sealing mechanism comprises a shell, and a transmission component and a movable brush strip arranged in the shell from top to bottom, the transmission component comprises a transmission rod, a compression rod is connected to one side of the transmission rod close to the hinged end of the door leaf, and a spring is provided on the other side, the end of the compression rod extends out of the shell, the transmission rod is connected to the movable brush strip through a plurality of arc-shaped rebound rubber strips, and a groove is provided on the bottom end surface of the shell for the movable brush strip to pass through.
[0007] Furthermore, an upper limit convex strip abutting against the top end of the movable brush strip is provided in the shell.
[0008] Furthermore, a mounting groove is provided at the bottom end of the door leaf, and the sinking sealing mechanism is embedded in the mounting groove.
[0009] Furthermore, the door leaf is provided with a stepped surface cooperating with the sealing strip.
[0010] Furthermore, the door leaf is provided with a clean window and a clean lock.
[0011] Furthermore, the surface of the door frame and the door leaf is coated with an antibacterial coating.
[0012] Compared with the prior art, the utility model has the following beneficial technical effects:
[0013] The utility model is suitable for a clean airtight ward door for an infection ward. The sealing strip and the settling sealing mechanism can seal the gap between the door leaf and the door frame and the ground after the door leaf is closed, so that the ward door can meet the airtightness requirements of the infection ward. Moreover, the settling sealing mechanism can be recovered into the bottom of the door leaf after the door leaf is opened, so as to avoid wear and tear and effectively increase the service life.

[0020] Many specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from the description, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0021] Example 1
[0022] like Figure 1-5As shown, a clean airtight ward door suitable for an infection ward comprises a door frame 1 and a door leaf 2 hingedly connected by hinges. The surfaces of the door frame 1 and the door leaf 2 are coated with an antibacterial coating, so there is no place for dirt to hide, which has an inhibitory effect on bacteria in the ward space. Each side of the door frame 1 is provided with a sealing strip 3, and the door leaf 2 is provided with a stepped surface 21 that cooperates with the sealing strip 3, so that the door leaf 2 can fit tightly with the sealing strip 3 after closing without any gap.
[0023] The door leaf 2 is provided with a clean window 22 and a clean lock 23, and medical staff can observe the indoor situation through the clean window 22. The glass of the clean window 22 is fireproof glass, which meets certain fire protection requirements. The bottom end of the door leaf 2 is provided with a mounting groove 24 along the length direction, and the mounting groove 24 is embedded with a sinking sealing mechanism 4.
[0024] The sedimentation sealing mechanism 4 includes a shell 41, and a transmission assembly and a movable brush strip 42 arranged in the shell 41 from top to bottom. The transmission assembly includes a transmission rod 43 that slides along the length direction of the shell 41. The transmission rod 43 is connected to a compression rod 44 on one side close to the hinged end of the door leaf 2, and a spring 45 is provided on the other side. The end of the compression rod 44 extends out of the side of the shell 41, and the spring 45 abuts against the inner wall of the shell 41. The bottom of the transmission rod 43 is connected to the movable brush strip 42 through a plurality of arc-shaped rebound rubber strips 46, and a notch is provided on the bottom end surface of the shell 41 for the movable brush strip 42 to pass through. An upper limit convex strip 47 abutting against the top of the movable brush strip 42 is provided in the shell 41.
[0025] When the door leaf 2 is closed, the door frame 1 will squeeze the compression rod 44, causing the transmission rod 43 to move axially, thereby driving the rebound rubber strip 46 to move downward, and the rebound rubber strip 46 will push the movable brush strip 42 through the notch to extend out of the shell 41 and abut against the ground, thereby closing the gap between the door leaf 2 and the ground. When the door frame 1 is opened, the compression rod 44 rebounds under the action of the spring 45, and the movable brush strip 42 rises back into the shell 41. In this way, through the joint action of the sealing strip 3 and the sedimentation sealing mechanism 4, a sealing effect can be achieved after the door leaf 2 is closed, meeting the use requirements of the infection ward.
[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
