[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Combine the following Figures 1 to 3 The utility model is described in detail.

[0022] A weld-free buckle edge structure of a fireproof door leaf comprises a door leaf 1, a door frame 2 is arranged around the door leaf 1, a sealing groove 101 is arranged on one side of the door leaf 1, bending blocks 102 are arranged on both sides of the middle of the sealing groove 101, a supporting block 103 is arranged at one end of the bending block 102, a sealing component is arranged on one side of the inner wall of the door frame 2, the sealing component swings along the axis, and the sealing component cooperates with the sealing groove 101.

[0023] First, one side of the door leaf 1 is hinged in the door frame 2, and then the door leaf 1 is controlled to deflect and engage with the door frame 2, thereby separating the indoor and outdoor areas.

[0024] When the door leaf 1 and the door frame 2 cooperate to close, the edge of the door leaf 1 will cooperate with the groove on the inner wall of the door frame 2, and the cooperation structure of the two is a buckle edge structure, so that the door leaf 1 can be directly connected with the door frame 2 more airtight when closed, thereby increasing its sealing.

[0025] Furthermore, the bending block 102 is made of elastic metal, the abutting block 103 is tilted and arranged at one end of the bending block 102, and a rubber layer is arranged on the surface of the opposite side of the abutting block 103, and the sealing assembly also includes a deflection groove 201 and a deflection rod 202, the deflection groove 201 is arranged on the inner side of the door frame 2, the deflection rod 202 is arranged in the middle of the deflection groove 201, the deflection rod 202 includes a deflection shaft 2021, a pressure block 2022 and a sealing block 2023, the deflection shaft 2021 is arranged at one end of the deflection rod 202, and the pressure block 2022 is arranged at the inner side of the door frame 2. It is arranged on one side of the deflection shaft 2021, the sealing block 2023 is arranged on one side of the deflection rod 202, the deflection shaft 2021 is hingedly arranged in the deflection groove 201, and the two ends of the deflection shaft 2021 are connected to the deflection groove 201 through a torsion spring, the pressure block 2022 is a convex block of the inclined protruding part on one side of the deflection shaft 2021 at the opening of the deflection groove 201, and the pressure block 2022 and the deflection rod 202 are arranged at a certain angle, the sealing block 2023 is a rectangular convex block arranged on one side of the deflection rod 202, and the sealing block 2023 cooperates with the sealing groove 101.

[0026] When the door leaf 1 and the door frame 2 cooperate to close, the door leaf 1 will first contact the pressure block 2022 of the protruding part on the inner wall of the door frame 2 at the opening of the deflection groove 201. Through the closing pressure, the protruding part will be forced to deflect along the deflection axis 2021 and shrink into the deflection groove 201, so that the door leaf 1 can be closed smoothly.

[0027] Then, when the pressure block 2022 is pressed and drives the deflection shaft 2021 to deflect, the deflection rod 202 connected to the deflection shaft 2021 will also be deflected, and the deflection rod 202 will drive the sealing block 2023 to move closer to the door leaf 1 when deflecting, and finally the sealing block 2023 will be embedded in the sealing groove 101. After being embedded in the sealing groove 101, the sealing block 2023 will abut against the abutting block 103, thereby applying pressure to the abutting block 103, allowing it to pass through the bending block 102. There is a certain deflection, and at the same time, because of the restoring elasticity of the bending block 102, the abutment block 103 will always be tightly fitted on both sides of the sealing block 2023, and the rubber layer on the abutment block 103 can be more sealed when the sealing block 2023 is fitted, and one side can complete the closing buckle edge of the door leaf 1 and the door frame 2, making it more sealed, and the buckle edge will not be a fixed setting welded, which will easily cause irreparable deformation due to damage during use, affecting the sealing.

[0028] The following is a specific implementation process of the present invention. First, one side of the door leaf 1 is hinged in the door frame 2, and then the door leaf 1 is controlled to deflect and engage with the door frame 2, thereby separating the indoor and outdoor areas. When the door leaf 1 and the door frame 2 cooperate to close, the door leaf 1 will first contact the pressure block 2022 of the protruding part on the inner wall of the door frame 2 at the opening of the deflection groove 201. Through the closing pressure, the protruding part will be forced to deflect along the deflection axis 2021 and shrink into the deflection groove 201, so that the door leaf 1 can be closed smoothly. Then, when the pressure block 2022 drives the deflection axis 2021 to deflect under pressure, it will drive the deflection rod 202 connected to the deflection axis 2021 to deflect as well, and the deflection rod 202 will drive the sealing block 2023 to move toward The door leaf 1 is brought together, and finally the sealing block 2023 is inserted into the sealing groove 101. After being inserted into the sealing groove 101, the sealing block 2023 will abut against the abutting block 103, thereby applying pressure to the abutting block 103, allowing it to undergo a certain deflection through the bending block 102. At the same time, due to the restoring elasticity of the bending block 102, the abutting block 103 will always be tightly fitted on both sides of the sealing block 2023, and the rubber layer on the abutting block 103 can be more sealed when the sealing block 2023 is fitted, and one side can complete the closed buckle edge of the door leaf 1 and the door frame 2, making it more sealed, and because the buckle edge is a fixed setting welded, it will not be easily damaged during use, resulting in irreparable deformation, affecting the sealing.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
