Description

Technical Field

[0001] This application relates to the technical field of sealing strips, specifically to the sealing strip for the box door. Background Technique

[0002] The sealing strip of the incubator is a key component for keeping the internal and external environments of the incubator isolated, and its quality directly affects the working effect and service life of the incubator. Good sealing performance can ensure a constant, pollution-free, and efficient working internal environment of the incubator, while damaged or aged sealing strips will cause many problems such as unstable internal temperature and decreased airtightness.

[0003] During the pressing process of common sealing strips, the deformed area of the sealing strip body is relatively large, thus reducing the service life of the sealing strip. Therefore, it is necessary to provide a sealing strip for the box door with less deformation during extrusion to solve the above problems and improve the service life of the sealing strip. Summary of the Invention

[0004] Based on the above problems existing in the prior art, the purpose of this application is to provide a sealing strip for the box door to solve the problems proposed in the above background technique.

[0005] The technical solution adopted by this application to solve its technical problems is: a sealing strip for the box door, used for sealing between the box body and the box door, including a box body and a sealing strip. An inner box is provided in the box body, and inner box protrusions are arranged around the inner box. The sealing strip sequentially includes an installation part, a bearing surface, an upper adjustment surface, a lower adjustment surface, a deformation point, a serrated part, a contact part, and a through cavity in a clockwise direction. The through cavity is located in the middle of the sealing strip and above the installation part. The sealing strip is installed on the inner box protrusions.

[0006] Further, an inner box door and an outer box door are hinged on one side of the box body. The size of the inner box door matches that of the inner box protrusions, the size of the outer box door matches that of the box body, and the size of the outer box door is larger than that of the inner box door.

[0007] Further, the material of the sealing strip is an elastic material.

[0008] Further, the installation part is U-shaped and the opening size is matched with the thickness of the inner box protrusions.

[0009] Further, two protrusions are provided above the installation part.

[0010] Further, the deformation point is arranged between the upper adjustment surface and the lower adjustment surface.

[0011] The beneficial effects of the present application are as follows: The door seal strip provided by the present application is provided with a seal strip. When the pressure-bearing surface is squeezed, only the pressure-bearing surface, the upper adjustment surface, and the lower adjustment surface deform, reducing the excessive deformation of the seal strip. Therefore, when the inner door performs the opening and closing actions, the deformation can be reduced, increasing the service life of the seal strip, and solving the technical problem that in the common seal strip, the deformed area of the seal strip body is relatively large during the pressing process, thereby reducing the service life of the seal strip.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to elaborate on the present application in detail.

[0022] To enable those skilled in the art to better understand the solution of this application, the technical solution in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0023] As Figures 1-4 shown, the technical solution provided by this application is: a box door sealing strip, including a box body 1 and a sealing strip 6. An inner box 2 is provided in the box body 1, and inner box protrusions 3 are arranged around the inner box 2. The sealing strip 6 is installed on the inner box protrusions 3.

[0024] As Figure 1 shown, an inner box door 4 and an outer box door 5 are hinged on one side of the box body 1. The size of the inner box door 4 matches that of the inner box protrusions 3. When the sealing strip 6 is installed on the inner box protrusions 3, the inner box door 4 can cover the area where the sealing strip 6 is installed on the inner box protrusions 3. The size of the outer box door 5 matches that of the box body 1, and the size of the outer box door 5 is larger than that of the inner box door 4.

[0025] As Figure 2 shown, the sealing strip 6 sequentially includes an installation part 61, a pressure-bearing surface 62, an upper adjustment surface 63, a lower adjustment surface 64, a deformation point 65, a serrated part 66, a contact part 67, and a through cavity 68 in a clockwise direction inside. The through cavity 68 is located in the middle of the sealing strip 6 and above the installation part 61.

[0026] The material of the sealing strip 6 is an elastic material, which can be silicone.

[0027] The installation part 61 is U-shaped and the opening size is matched with the thickness of the inner box protrusions 3, ensuring that the sealing strip 6 can be nested on the inner box protrusions 3 through the installation part 61. Two protrusions 611 are arranged above the installation part 61, which can increase the friction of the sealing strip 6.

[0028] The deformation point 65 is arranged between the upper adjustment surface 63 and the lower adjustment surface 64. When the pressure-bearing surface 62 is subjected to pressure, the upper adjustment surface 63 and the lower adjustment surface 64 change the included angle between the upper adjustment surface 63 and the lower adjustment surface 64 with the deformation point 65 as the center.

[0029] Working principle: As Figure 3 shown, align the installation part 61 on the sealing strip 6 with the inner box protrusions 3 and embed it until the deepest part of the installation part 61 abuts against the inner box protrusions 3. At this time, the contact part 67 contacts the box body 1, and the protrusions 611 abutting against the inner box protrusions 3 increase the friction of the sealing strip 6 on the inner box protrusions 3.

[0030] Close the inner box door 4. The inner box door 4 contacts the pressure-bearing surface 62, and the sealing strip 6 deforms. At this time, with the deformation point 65 as the center, the upper adjustment surface 63 and the lower adjustment surface 64 reduce the angle between the upper adjustment surface 63 and the lower adjustment surface 64, forming a seal between the inner box 2 and the inner box door 4.

[0031] In summary, by providing the sealing strip 6, when the pressure-bearing surface 62 is squeezed, only the pressure-bearing surface 62, the upper adjustment surface 63, and the lower adjustment surface 64 deform, reducing the excessive deformation of the sealing strip 6. Therefore, when the inner box door 4 is opened and closed, the deformation can be reduced, increasing the service life of the sealing strip 6, and solving the technical problem that in the common sealing strip 6 during the pressing process, the deformed area of the sealing strip 6 body is relatively large, thus reducing the service life of the sealing strip 6.

[0032] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
