Description

Technical Field

[0001] This utility model relates to the field of protective equipment, and in particular to a double-sealed protective door. Background Technology

[0002] Protective doors typically use built-in lead plates to shield against radiation and are widely used in radiation-exposed work areas such as hospital CT scan rooms. In some applications, a high degree of airtightness is required when the protective door is closed; therefore, a sealing strip is often installed between the protective door and the door frame.

[0003] Currently, most protective doors use a single sealing strip between the door and the frame. The sealing effect of a single strip is limited, and its stability decreases with aging after long-term use. Therefore, this application proposes a double-seal protective door to improve its airtightness. Utility Model Content

[0020] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In this utility model, such as Figure 1-3 As shown, a double-sealed protective door is provided, including a door frame 1 and a door body 2. The inner edge of the door frame 1 has a first support surface 3, a second support surface 4 disposed outside the first support surface 3, and a third support surface 5 connected to the outside of the second support surface 4. The second support surface 4 is perpendicular to the first support surface 3, and the first support surface 3 is parallel to the second support surface 4. The outer edge of the door body 2 has a third profile surface 6 and a second profile surface 7 disposed inside the third profile surface 6. The inner edge of the second profile surface 7 is connected to the inner surface of the door body 2. When the door frame 1 is closed, the first support surface 3 is parallel to the inner surface of the door body 2, the second profile surface is parallel to the second profile surface 7 and has an air storage gap, and the third support surface 5 is parallel to the third profile surface 6. Sealing strips 10 are provided at the intersection of the first support surface 3 and the second support surface 4 on the door frame 1 and at the intersection of the third profile surface 6 and the second profile surface 7 on the door body 2.

[0025] As shown in the figure, the door body 2 of this invention has sealing strips 10 installed on both the door frame 1 and the door body 2 during use. This allows for sealing using two sets of sealing strips 10, improving the stability of the seal. Furthermore, by creating an air storage gap between the second support surface 4 and the second profile surface 7, and installing sealing strips 10 at both ends of this gap, the sealing strips 10 can be arranged vertically on the door body 2 at intervals, reducing the space occupied in the lateral direction of the door frame 1 and the door body 2, thus reducing the width of the door frame 1. Moreover, the air storage gap between the second support surface 4 and the second profile surface 7 not only prevents interference between the door frame 1 and the door body 2 during opening and closing, but also creates a deformation space for the sealing strips 10. This provides space for the sealing strips 10 to deform under pressure, preventing excessive compression and further extending their service life.

[0026] In the illustrated embodiment, more specifically, regarding the structure of this utility model, the first support surface 3 is recessed at the edge near the second support surface 4 to form a first fixing groove 8 capable of installing the sealing strip 10.

[0027] As shown in the figure, this allows the sealing strip 10 to be pressed and deformed towards the first fixing groove 8 during the door closing operation, thus preventing the sealing strip 10 from coming off.

[0028] In the illustrated embodiment, more specifically, regarding the structure of this utility model, the third surface 6 is recessed near the edge of the second surface 7 to form a second fixing groove 9 capable of installing the sealing strip 10.

[0029] As shown in the figure, this allows the sealing strip 10 to be pressed and deformed towards the second fixing groove 9 during the door closing operation, thus preventing the sealing strip 10 from coming off.

[0030] In the illustrated embodiment, for the structure of this utility model, more specifically, the sealing strip 10 includes an installation part 1002 and a sealing part 1001 connected to the installation part 1002; the sealing part 1001 includes an arc-shaped edge 10011, a first connecting rib 10012 and a second connecting rib 10013 respectively disposed on both sides of the arc-shaped edge 10011, the first connecting rib 10012 and the second connecting rib 10013 are respectively connected to the installation part 1002, the first connecting rib 10012 extends obliquely outward in a direction away from the installation part 1002, and the middle section of the second connecting rib 10013 bends toward the first connecting rib 10012.

[0031] As shown in the figure, the arc-shaped edge 10011, the first connecting rib 10012, and the second connecting rib 10013 form a deformable cavity. The arc-shaped edge 10011 serves as the direct contact part for sealing and extrusion, and its different parts exhibit better stability and deformation consistency when compressed. Moreover, when the arc-shaped edge 10011 is compressed, as shown in the figure, the first connecting rib 10012, connected to one end of the arc-shaped edge 10011, can deform outward, while the middle section of the second connecting rib 10013 deforms inward.

[0032] In the illustrated embodiment, more specifically, the second connecting rib 10013 is formed with a laterally extending shielding rib 11.

[0033] As shown in the figure, by setting the shielding rib 11, the edge of the first fixing groove 8 or the second fixing groove 9 can be covered, which not only improves the aesthetics of the installation position of the sealing strip 10, but also prevents external dust from entering.

[0034] In the illustrated embodiment, for the structure of this utility model, more specifically, the door body 2 includes a frame keel 12, a decorative panel 13 covering the outside of the frame keel 12, and a lead plate 14 disposed between the frame keels 12. The third profile 6 and the second profile 7 are located at the position of the frame keel 12; the frame keel 12 forms the second fixing groove 9.

[0035] As shown in the figure, the frame keel 12 includes keel bodies disposed on the four sides of the door body 2. The keel bodies are plate-frame structures, and lead plates 14 are disposed between the keel bodies. By positioning the third profile 6 and the second profile 7 at the keel body positions, the keel body can have multiple bending segments, thereby increasing the bending strength of the keel body through these bending segments.

[0036] It should be noted that in the accompanying drawings of this utility model, only... Figure 3 The cross-sectional view shows the installation of sealing strips at the locations of the two longitudinal keel bodies. It should be understood that the structural representation of the transverse keel body is based on the structure of the longitudinal keel body.

[0037] In the illustrated embodiment, for the structure of this utility model, more specifically, the decorative panel 13 on the inner surface of the door body 2 is bent and extended from the second profile 7 to the second fixing groove 9, and the decorative panel 13 on the outer surface of the door body 2 is bent and extended to the third profile; the sealing strip 10 of the second fixing groove 9 covers the edge of the decorative panel 13.

[0038] As shown in the figure, the blocking rib 11 extends laterally to block the decorative panel 13. The sealing strip 10 extends directly from the decorative panel 13 on the other side of the blocking rib 11 into the second fixing groove 9. In this way, the sealing strip 10 can be used to block the edge of the decorative panel 13 to further improve the aesthetics.

[0039] In the illustrated embodiment, for the structure of this utility model, more specifically, the mounting part 1002 includes a mounting block 10021 and anti-reverse ribs 10022 formed on both sides of the mounting block 10021, the anti-reverse ribs 10022 extending obliquely outward in the direction toward the sealing part 1001.

[0040] In the illustrated embodiment, more specifically, for the structure of this utility model, arc-shaped abutment portions are formed between the second support surface 4 and the third support surface 5, and between the second profile 7 and the inner surface of the door body 2.

Each embodiment focuses on its differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0042] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
