[0002] A steel door with a T-shaped structure is also called a T-type steel door. The cross-section of a T-shaped steel door is T-shaped, and its T-shaped edge structure can fit tightly with the surface of the door frame. Visually, the surface of the door panel protrudes and is not flush with the door frame. Compared with conventional flat doors, its door gap is smaller, which effectively blocks the penetration of sound, improves the sound insulation effect, and has better sealing. It is a common door choice in modern buildings.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the T-shaped structure at the edge of the door panel of the existing T-shaped steel door is fixed and cannot be embedded in the door panel. In order to avoid the T-shaped protruding position getting stuck in the door frame when opening, it must be installed with customized door frames, door locks, and three-pronged hinges and other hardware, which is costly and cannot be applied to ordinary steel doors. The adaptability is poor and needs further improvement. Utility Model Content

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0024] Embodiment 1:

[0025] like Figure 1-7 As shown, the steel door with an embedded T-shaped structure of the utility model includes a door leaf assembly 1 and a door panel assembly 2, the door leaf assembly 1 includes a top frame 101, and the left and right sides of the bottom end of the top frame 101 are fixedly connected with frame frames 102, the door leaf assembly 1 includes an inner door panel 103, the inner door panel 103 is located between the two groups of frame frames 102, and the rear end of the inner door panel 103 is provided with four groups of fastening bolts 106, the door panel assembly 2 includes an outer door panel 201, the outer door panel 201 is located at the front end of the inner door panel 103, the right end of the outer door panel 201 is fixedly connected with a main baffle 202, the left end of the outer door panel 201 is provided with a baffle groove 204, and the baffle groove 204 is provided with an auxiliary baffle 203.

[0026] like Figure 1-7 As shown, the inner walls at both ends of the baffle groove 204 are provided with limiting grooves 206 , and the upper and lower ends of the auxiliary baffle 203 are fixedly connected to limiting blocks 205 , and the limiting blocks 205 are located in the limiting grooves 206 .

[0027] like Figure 1-7 As shown, two groups of telescopic slots 207 are opened at the right end of the baffle slot 204, and springs 208 are arranged in the telescopic slots 207, and the left ends of the springs 208 are fixedly connected to sliding blocks 209.

[0028] like Figure 1-7As shown, the left ends of the two sets of sliding blocks 209 are fixedly connected to the telescopic rods 210 , and the left ends of the two sets of telescopic rods 210 are fixedly connected to the right end of the auxiliary baffle 203 .

[0029] During implementation, through the setting of the spring 208 and the telescopic rod 210, the outer door panel 201 rotates when the door leaf is opened. At this time, through the setting of the rear end inclined surface of the auxiliary baffle 203 and the front end inclined surface of the fixed plate 108, the auxiliary baffle 203 is embedded in the baffle groove 204 under force, and at the same time, the auxiliary baffle 203 drives the telescopic rod 210 to move, and the telescopic rod 210 drives the sliding block 209 to move into the telescopic groove 207 so that the spring 208 is deformed under force. When closing the door, the spring 208 resets and drives the auxiliary baffle 203 to move and abut against the fixed plate 108. The embedded design of the auxiliary baffle 203 can be used with conventional hinges, hardware and door frames for the installation of door leaves, which reduces the cost while ensuring the good sound insulation and sealing advantages of the T-shaped structure, and has better adaptability than the fixed T-shaped structure.

[0030] Embodiment 2:

[0031] like Figure 1-7 As shown, based on the first embodiment, the utility model provides a technical solution for a steel door with an embedded T-shaped structure: a fixing plate 108 is fixedly connected to the front end of the left side frame 102, and a bevel is provided at the front end of the fixing plate 108 and the rear end of the auxiliary baffle 203.

[0032] like Figure 1-7 As shown, two groups of card slots 104 are opened at the front end of the inner door panel 103 , and two groups of card strips 105 are fixedly connected to the rear end of the outer door panel 201 , and the card strips 105 are all located in the card slots 104 .

[0033] like Figure 1-7 As shown, threaded holes 107 are provided at the rear end of the inner door panel 103 and the rear ends of the two groups of clamping strips 105 , and the front parts of the four groups of fastening bolts 106 are threadedly connected to the threaded holes 107 .

[0034] During implementation, through the setting of the door leaf assembly 1 and the door panel assembly 2, the fastening bolt 106 is rotated to separate it from the threaded hole 107, and through the setting of the slot 104 and the clamping strip 105, the outer door panel 201 is pushed to separate it from the inner door panel 103, so that personnel can disassemble and assemble the outer door panel 201 and replace it with an ordinary flat door panel according to needs. Compared with the fixed T-type structure, it has higher flexibility, the overall structure is simple and stable, and has good practicality.

[0035] The advantages of this technical solution in practical applications include but are not limited to the following:

[0036] 1. Through the setting of the spring 208 and the telescopic rod 210, the outer door panel 201 rotates when the door leaf is opened. Through the setting of the rear end inclined surface of the auxiliary baffle 203 and the front end inclined surface of the fixed plate 108, the auxiliary baffle 203 is embedded in the baffle groove 204 under force, and the door leaf can be installed with conventional hinges, hardware and door frames. While ensuring the good sound insulation and sealing advantages of the T-shaped structure, the cost is reduced, and it has better adaptability than the fixed T-shaped structure.

[0037] 2. By rotating the fastening bolt 106 to separate it from the threaded hole 107, the arrangement of the card slot 104 and the card strip 105 allows personnel to disassemble and assemble the outer door panel 201 and replace it with an ordinary flat door panel as needed. Compared with the fixed T-type structure, it has higher flexibility, the overall structure is simple and stable, and has good practicality.

[0038] The technical solution is to set the spring 208 and the telescopic rod 210, so that the outer door panel 201 rotates when the door leaf is opened. At this time, through the setting of the rear end inclined surface of the auxiliary baffle 203 and the front end inclined surface of the fixed plate 108, the auxiliary baffle 203 is forced to be embedded in the baffle groove 204, and at the same time, the auxiliary baffle 203 drives the telescopic rod 210 to move, and the telescopic rod 210 drives the sliding block 209 to move into the telescopic groove 207 so that the spring 208 is forced to deform. When closing the door, the spring 208 resets and drives the auxiliary baffle 203 to move and abut against the fixed plate 108, and the fastening bolt 106 is rotated to separate it from the threaded hole 107. Through the setting of the card slot 104 and the card strip 105, the outer door panel 201 is pushed to separate it from the inner door panel 103, so that personnel can disassemble and assemble the outer door panel 201 and replace it with an ordinary flat door panel according to needs.

[0039] The above are only exemplary embodiments of the present disclosure and cannot be used to limit the scope of the present disclosure. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure. After considering the disclosure of the specification and practice, those skilled in the art will easily think of other embodiments of the present disclosure.
