The length direction of the fixing plate is defined as the vertical direction and the width direction of the fixing plate is defined as the horizontal direction. The rear side of the fixing plate is used to connect with the end face of the door panel. A sealing groove is provided on the front side of the fixing plate, and a retaining edge is provided on both the left and right side walls of the sealing groove.

[0006] The sealing strip is adapted to the sealing groove and is located within the sealing groove. The sealing strip has a stop surface that cooperates with the stop edge in the vertical direction.

[0007] The beneficial effects are as follows: When using the door panel sealing structure of this utility model, firstly, the fixing plate is installed on the door panel with the sealing groove on the side away from the door frame panel, and then the sealing strip is installed in the sealing groove. When the door panel and door frame panel are closed, the sealing strip can fit tightly against the door frame panel, thereby sealing the gap between the door panel and door frame panel, thus improving the sealing effect and achieving the functions of light insulation, sound insulation, and noise reduction.

[0008] Furthermore, the sealing strip is made of EPDM rubber.

[0009] Beneficial effects: EPDM rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, and water vapor resistance. It has a long service life, good elasticity, and good sealing effect.

[0010] Furthermore, the sealing strip includes a sealing part, a connecting part, and a sliding part. The sealing part extends to the outside of the sealing groove to seal between the door panel and the door frame panel. The sliding part has an inverted isosceles trapezoidal structure and the front end face of the sliding part forms the stop surface.

[0011] Beneficial effects: It facilitates the installation of the sealing strip. When using it, simply press the sliding part between the two retaining edges into the sealing groove.

[0012] Furthermore, the connecting part has a T-shaped structure, and two sliding grooves are formed between the stopping surfaces of the connecting part and the sliding part, which are respectively placed on the left and right sides of the connecting part. The two sliding grooves are set one-to-one with the two stops and are stopped and engaged with the corresponding stops in the front and rear directions.

[0013] Beneficial effects: Improves the stability of the sealing strip when it is installed in the sealing groove, preventing the sealing strip from shaking.

[0014] Furthermore, the sealing part is provided with a sealing weight reduction hole, the connecting part is provided with a connecting weight reduction hole, and the sliding part is provided with a sliding weight reduction hole.

[0015] Beneficial effects: Reduces material usage and lowers costs.

[0016] Furthermore, the fixing plate has multiple fixing and weight reduction holes.

[0017] Beneficial effects: Reduces material usage and lowers costs.

[0018] Furthermore, limiting plates are provided on both the left and right sides of the rear side of the fixed plate. The two limiting plates and the fixed plate form a sliding groove that matches the door panel, and the sliding groove and the door panel slide together.

[0019] Beneficial effects: Simple structure and easy installation.

[0020] Furthermore, the mounting plate is made of aluminum alloy.

[0021] Beneficial benefits: Low price, flexible, and easy to install.

[0022] Furthermore, the left end face of the fixing plate is curved.

[0023] Beneficial effects: When the door is opened, the left end of the fixing plate faces outward, which is aesthetically pleasing. At the same time, it makes it easier for the left end of the fixing plate to fit tightly with the sealing element installed inside the door frame, thus improving the sealing effect.

[0024] Furthermore, the fixing plate is made by integral molding.

[0025] Beneficial effects: Improves overall stability and extends service life. Attached Figure Description
