Detailed implementation manners
[0025] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
[0026] Refer to Figures 1-7 , the present utility model provides a technical solution:
[0027] A T-shaped door, comprising a door frame and a door leaf. The door frame includes an upper frame 7, a left frame 5, a right frame 6 and a bottom frame 8. The door leaf includes a mother door leaf 1, a mother-child door leaf 2, a child door leaf 3 and a child-child door leaf 4. A middle frame 9 is provided between the upper frame 7 and the door leaf, and a window grille 10 is installed between the middle frame 9 and the upper frame 7. The child-child door leaf 4 is connected to the left frame 5 through a T-shaped capless flag hinge 11 and a hinge box 12. The T-shaped capless flag hinge 11 and the hinge box 12 are fixed to the child-child door leaf 4 and the left frame 5 by screws. A first rotation-limiting convex block 13 is provided on one side of the child-child door leaf 4 close to the left frame 5, and a first limiting convex block 14 is provided on one side of the left frame 5 close to the child-child door leaf 4. When the child-child door leaf 4 rotates with the T-shaped capless flag hinge 11 as the rotation axis, before the opening angle of the door leaf reaches 180° or when it rotates to the maximum angle before the door leaf collides with the wall, the first rotation-limiting convex block 13 and the first limiting convex block 14 come into contact with each other in advance to prevent the child-child door leaf 4 from rotating, thereby controlling the maximum opening angle of the child-child door leaf 4 and achieving the purposes of rotation limitation and protection; when the child-child door leaf 4 is in the closed state, the first rotation-limiting block and the left frame 5 form a T-shaped coverage. A first buffer block 17 is provided on one side of the left frame 5 away from the hinge box 12 to buffer the impact force when the child-child door leaf 4 is closed. At the same time, in the closed state, a Z-shaped gap is formed among the first buffer block 17, the left frame 5, the child-child door leaf 4 and the first rotation-limiting convex block 13 to reduce air leakage. The setting between the mother-child door leaf 2 and the right frame 6 is the same as the setting between the child-child door leaf 4 and the left frame 5.
[0028] The connection between the sub-door leaf 3 and the sub-sub-door leaf 4 also adopts a T-shaped capless flag hinge 11 and a hinge box 12. The T-shaped capless flag hinge 11 and the hinge box 12 are fixed on the sub-sub-door leaf 4 and the sub-door leaf 3 by screws. A second rotation-limiting convex block 15 is provided on the side of the sub-door leaf 3 close to the sub-sub-door leaf 4, and a second limiting convex block 16 is provided on the side of the sub-sub-door leaf 4 close to the sub-door leaf 3. When the sub-door leaf 3 rotates with the T-shaped capless flag hinge 11 as the rotation axis, before the opening angle of the door leaf reaches 180° or when it rotates to the maximum angle before the door leaf collides with the wall, the second rotation-limiting convex block 15 and the second limiting convex block 16 come into contact with each other in advance to prevent the sub-door leaf 3 from rotating, thereby controlling the maximum opening angle of the sub-door leaf 3 and achieving the purpose of rotation limitation and protection; when the sub-door leaf 3 is in the closed state, the second rotation-limiting block forms a T-shaped covering with the sub-sub-door leaf 4. A second buffer block 18 is provided on the side of the sub-sub-door leaf 4 away from the hinge box 12 to buffer the impact force when the sub-door leaf 3 is closed. At the same time, in the closed state, a Z-shaped gap is formed between the second buffer block 18, the sub-door leaf 3, the sub-sub-door leaf 4 and the second rotation-limiting convex block 15 to reduce air leakage. The setting between the mother and sub-door leaf 2 and the mother door leaf 1 is the same as the setting between the sub-door leaf 3 and the sub-sub-door leaf 4.
[0029] Under normal circumstances, only the mother door leaf 1 needs to be opened to meet the passage; when there are large objects that need to pass through, the mother door leaf 1 and the sub-door leaf 3 can be opened simultaneously; when there are even larger objects that need to pass through, all the door leaves can be opened simultaneously. The door leaves that do not need to be opened can be fixed by bolts.
[0030] The above is only the preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields.
