[0028] like Figures 1-7 As shown, a door structure that is easy to assemble includes a door frame 1, a door core 2 hinged inside the door frame 1, and a door panel 3 fixed to at least one surface of the door core 2 in the thickness direction by a suspension structure 5. A door core 2 is hinged inside the outer frame 1. A door panel 3 is fixed to at least one surface of the door core 2 in the thickness direction via a suspension structure 5. This allows the door to be assembled during installation, reducing the overall weight of the door during initial handling and facilitating its movement by construction workers. Furthermore, if the door panel 3 is damaged during later use, it is easy to repair and replace. The door panel 3 is made of firewood. The suspension installation method of this application does not require glue and allows for individual replacement of the door panel 3, reducing the cost of later maintenance and replacement. Construction is also more convenient because the door core 2 can be installed first, and the door panel 3 can be hung later. The door panel 3 can be hung after on-site construction is completed, preventing damage to the door panel 3 during construction and achieving a new delivery standard. Example 2

[0029] like Figures 1-7 As shown, door panels 3 are fixed to the two surfaces of the door core 2 in the thickness direction by a suspension structure 5. Of course, door panels 3 can also be suspended on both sides of the door core 2 in the thickness direction. like Figure 1 As shown, the hanging structure 5 includes several hooks 51 and several hook positions 52. One of the hooks 51 and hook positions 52 is provided on the door panel 3, and the other is provided on the door core 2. At least one hook 51 is hung on each hook position 52. The hanging structure 5 is used to securely hang the door panel 3 on the door core 2. like Figure 3 , Figure 4 As shown, the hook 51 is fixed to the door panel 3, the door core 2 is provided with several hook positions 52, and the door core 2 is provided with several horizontal beams 4 distributed from top to bottom. Each horizontal beam 4 is provided with a hook position 52. The hook positions 52 can be set on the inner wall of the door core 2, or the hook positions 52 can be set on the horizontal beams 4. like Figure 4As shown, hook positions 52 are provided on both sides of the crossbeam 4. At least part of the hook 51 is hung on the hook position 52, so that the door panel 3 is hung on the door core 2. The hook position 52 has a long groove structure. At least one hook position 52 with a long groove structure is provided on both sides of the crossbeam 4 along the axial direction of the crossbeam 4. like Figure 7 As shown, a limiting structure 6 is provided between the door core 2 and the door panel 3 to prevent the door panel 3 from shifting along its width direction. The limiting structure 6 includes a limiting pin 61 and a limiting hole 62. Either the limiting pin 61 or the limiting hole 62 is provided on the door panel 3, and the other is provided on the door core 2. This prevents the door panel 3 from shifting left or right when it is hung on the door core 2. The limiting structure 6 can enhance the stability of the door panel 3 when it is hung on the door core 2. like Figure 7 As shown, the hooks 51 fixed on one of the door panels 3 and the hooks 51 fixed on the other door panel 3 are symmetrically distributed, which makes it convenient for the door panel 3 to be hung on the door core 2. The two surfaces of the door core 2 in the thickness direction are respectively fixed with protective plates 7. The protective plates 7 are used to enhance the overall strength of the door core 2. The protective plates 7 are provided with a hanging clearance opening 71 for the hooks 51 to pass through. The clearance opening 71 allows the hooks 51 to pass through the protective plates 7 and hang on the hook position 52. Example 3

[0030] The hook 51 is fixed to the door panel 3 by screws, so that the hook 51 is assembled on the door panel 3. The width distance between the two hooks 51 on both sides of the door panel 3 is the same as the width of the inner frame of the door core 2, which further ensures that the door panel 3 will not move along the width of the door core 2 when it is hung on the door core 2. Meanwhile, hook 51 and hook position 52 are also provided with stepped surfaces. When hook 51 is hooked in the hook position, the stepped surfaces on hook 51 and hook position 52 cooperate with each other. First, it makes it easier for hook 51 to be hooked in the hook position 52. Second, once hook 51 is hooked in the hook position 52, it is not easy for it to come off.
