[0021] Example:

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0023] Existing door seal structures such as Figure 4 As shown, the main body is an openable main door panel, which is hinged to the housing via a large hinge 6. A door groove specifically for installing a small door structure is provided on the main door panel, and the outer door panel 1 within the door groove is hinged to the main door panel via a door hinge 5. Pressure plates 4 are provided at adjacent ends of the outer door panel 1 and the inner door lining 2 of the main door panel. The pressure plates 4 on the outer door panel 1 are fixed to the vertical surface by rivets 7. An inner door rubber strip 8 is provided between the outer door panel 1 and the inner door lining 2 of the main door panel. The inner door rubber strip 8 is fixed to the PVC material plate 3 of the outer door panel 1 by rivets 7 and pressure plates 4, and the other end of the inner door rubber strip 8 presses against the PVC material plate 3 of the inner door lining 2 of the main door panel. The PVC material plate 3 on the inner door lining 2 of the main door panel has an F-shaped cross-section and a notch at one end, which is engaged with the vertical notch of the inner door lining 2 of the main door panel. The PVC material 3 of the outer door panel 1 has a Z-shaped cross section and a notch is provided at the end. The notch is fixed at the horizontal notch of the outer door panel 1.

[0024] A door seal structure, such as Figure 1 As shown, this design primarily uses a container with a small door structure. A main door panel, which can open and close relative to the container body, is located at the rear or side of the door. The description focuses on the hinged portion of the small door; therefore, the door liner 2 represents the main door panel. The main door panel is hinged to the container body via a large hinge 6, allowing the main door to rotate and open relative to the container body. A dedicated door groove is provided on the hinged side of the main door panel for installing the small door structure, which is the outer door panel 1. The outer door panel 1 is hinged to the door liner 2 via a door hinge 5, allowing the outer door panel 1 to hinge relative to the door liner 2. This forms the main large and small door structure.

[0025] like Figure 1As shown, notches are provided at the hinge ends of both the inner door liner 2 and the outer door panel 1. The notch on the outer door panel 1 is larger, directly removing the original horizontal panel structure. The inner door liner 2 is the opposite, with a smaller opening, retaining the horizontal panel structure. Therefore, the three-joint PVC panel 9 must be designed with a Z-shaped cross-section for installation on the outer door panel 1, with two flat and opposite ends, and notches at the ends for fitting into the wall panel at the notch on the outer door panel 1. The three-joint PVC panel 9 only connects to vertical panels. The corresponding PVC panel 3 has an F-shaped cross-section structure, with an opening at the long end and the other end used directly as an opening. The two openings are perpendicular to each other, corresponding to the vertical and horizontal panel structures on the inner door liner 2.

[0026] In addition, such as Figure 2 As shown, one end of the three-joint PVC board 9 is also provided with an outwardly protruding riveting plate 13, and the middle connecting section has a horizontal groove, which points to the other end away from the riveting plate 13. The opening direction of the groove of the three-joint PVC board 9 is perpendicular to the direction of the end notch. The opening of the groove is also provided with a reverse-extending limiting head 11, which is designed to extend beyond the groove, that is, the limiting head 11 and the groove form a loop structure. A protrusion 12 is added to the inner side of the limiting head 11 to further enhance the subsequent anti-detachment function.

[0027] An inner door strip 8 with a flared opening 10 is embedded on the back of the three-joint PVC panel 9, such as... Figure 3 As shown, the other end of the inner door strip 8 abuts against the inner door lining 2. The side of the inner door strip 8 that abuts against the inner door lining 2 is spherical, while the side that fits into the outer door panel 1 is flat. To facilitate fitting, the width of the fitting side needs to be widened to ensure that there is a protrusion on the right side that can hook onto the protrusion 12. The fitting side of the inner door strip 8 has a flared opening 10, which corresponds to the groove of the three-joint PVC board 9. The inner door strip 8, the limiting head 11, and the protrusion 12 are integrally formed.

[0028] One end of the three-joint PVC panel 9 is inserted into the notch of the outer door panel 1 through a notch, and the other end is then riveted to the notch wall panel of the outer door panel 1 by rivets 7. The riveting plate 13 is designed for easy installation, facilitating hole alignment and tightening. The PVC panel 3 is directly inserted into the notch wall panel of the door lining 2 through a notch. The door inner rubber strip 8 is inserted into the groove on the back of the three-joint PVC panel 9 through the flared opening 10. The protruding part is inserted into the loop structure formed by the limiting head 11, the protrusion 12, and the back of the three-joint PVC panel 9, making the whole fixed and stable and not easy to fall off. The rivet 7 and pressure plate 4 on one side have been eliminated and replaced with a more ingenious plug-in limiting structure, making the installation easier and increasing the pre-tightening force between the door inner rubber strip 8 and the outer door panel 1 and door inner lining 2, further preventing the rubber strip from falling off.

[0029] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
