[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0029] like Figures 1-2 As shown, a door structure with a large opening angle includes: a door leaf 1, a door frame 2, and a concealed hinge 3. A vertical side wall of the door leaf 1 is rotatably connected to the door frame 2 through the concealed hinge 3.

[0030] The concealed hinge 3 includes two rotatably connected leaf plates, which are fixedly connected to the door leaf 1 and the door frame 2 respectively. The leaf plate on the door frame 2 is flush with the edge of the door frame 2 near the opening side of the door leaf 1.

[0031] By using concealed hinges 3, and with the leaf plate on the door frame 2 flush with the edge of the door frame 2 near the opening side of the door leaf 1, this design reduces the limitation of the traditional hinge on the opening angle of the door leaf 1, thereby achieving a larger opening angle, which facilitates the entry and exit of people and large items. For example, when moving large objects such as furniture and equipment, the door leaf with a large opening angle can avoid collisions and make passage smoother.

[0032] The door leaf 1 includes an inner panel 101, an outer panel 102, and a side panel 103. The inner panel 101 and the outer panel 102 are parallel and are fixedly connected on both sides by the side panel 103. The outer panel 102 has flanges on both sides for covering the door gap. The flanges are arranged to avoid the door frame 2 during the rotation of the door leaf 1.

[0033] The flanges on both sides of the outer panel 102 not only cover the door gaps but also serve a decorative purpose. They make the door look more complete and unified, reduce the abruptness caused by the door gaps, further enhance the visual effect of the door, and make the whole door look more beautiful and elegant.

[0034] like Figure 1 As shown, a stepped surface 201 is provided on the door frame 2. The stepped surface 201 is used to install the concealed hinge 3 and is adapted to the thickness of the door leaf 1.

[0035] like Figure 1As shown, the first sealing strip 4 is arranged at the corner of the door frame 2 adjacent to the step surface 201.

[0036] The first sealing strip 4 is arranged at the corner of the door frame 2 adjacent to the step surface 201, which can effectively fill the gap between the door leaf 1 and the door frame 2 when the door leaf 1 is closed. When the door leaf 1 is closed, the sealing strip will be extruded to form a tight sealing barrier to prevent air, dust, rainwater, etc. from entering the room from the gap.

[0037] As shown in the drawings, Figure 2 The two side edges of the side plate 103 are respectively provided with clamping parts 104, which are respectively matched with the edges of the inner panel 101 and the flanges of the outer panel 102.

[0038] The clamping parts 104 are arranged, so that in the production process, the workers only need to align the clamping parts 104 of the side plate 103 with the edges of the inner panel 101 and the flanges of the outer panel 101 for clamping, which can complete the positioning and facilitate the subsequent welding work, greatly improve the production efficiency, and can guarantee the overall quality and precision of the door leaf 1.

[0039] As shown in the drawings, Figure 2 And Figure 4 The side plate 103 is provided with a right-angled corner at the matching position of the flange, and a clamping groove 105 is arranged at the right-angled corner, which is used to arrange the second sealing strip 5.

[0040] When the door leaf 1 is closed, there will inevitably be some tiny gaps between the side plate 103 and the flange, and the second sealing strip 5 installed in the clamping groove 105 can tightly fit in these gaps to effectively fill the gaps; the arrangement of the clamping groove 105 provides convenience for the installation of the second sealing strip 5, and can improve the firmness of the second sealing strip 5.

[0041] As shown in the drawings, Figure 3 The first sealing strip 4 comprises a matching part 401 and an arc-shaped part 402, one side edge of the arc-shaped part 402 is fixedly connected with the matching part 401, and the other side edge is arranged in a spaced manner with the matching part 401 to form an avoiding opening 403.

[0042] The matching part 401 is fixedly connected with the corner of the door frame 2 adjacent to the step surface 201, and the avoiding opening 403 is located away from the step surface 201.

[0043] The design of the avoiding opening 403 makes the arc-shaped part 402 better adapt to the movement during the opening and closing of the door leaf 1, avoids excessive friction with the door leaf 1, reduces the wear of the sealing strip itself, prolongs the service life, and reduces the frequency of frequent replacement due to damage of the sealing strip.

[0044] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the inventive concept, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application.
