[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 fireproof door for an elevator comprises a main body 1, a closing block 2 is arranged on one side of the main body 1, a fitting opening 201 is arranged on one side of the closing block 2, a fitting block 204 is arranged on one side of the closing block 2 away from the fitting opening 201, a fitting inclined surface 202 is arranged between the fitting block 204 and the fitting opening 201, a correction component is arranged on one side of the fitting opening 201, and the side of the correction component fitting the fitting block 204 is pressed and rotated, the closing block 2 is a convex block on the opposite side of the main body 1, the fitting opening 201 and the fitting block 204 arranged on the closing block 2 on the side opposite to the main body 1 are staggered and matched, and the fitting inclined surface 202 is an inclined surface extending from one side of the fitting block 204 to connect to the fitting opening 201.

[0023] First, when a fire occurs, the flame is blocked by closing the main body 1 to prevent the flame from spreading into the elevator. When the main body 1 is closed, the closing blocks 2 arranged on the opposite side will fit together. When fitting together, the interlocking openings 201 and the interlocking blocks 204 arranged alternately on the two will fit together, so that a tortuous seal is formed at the closed part of the main body 1, so that the flame cannot enter the elevator through the bend.

[0024] When the engaging block 204 is engaged with the engaging opening 201, the vibration generated when the main body 1 moves may make it impossible to align accurately, resulting in a certain error in the engaging inclined surface 202 at the bend between the engaging opening 201 and the engaging block 204. At this time, the engaging inclined surfaces 202 can be fitted together and move along the engaging inclined surfaces 202 when closing to correct the error between the engaging opening 201 and the engaging block 204 so that the engaging inclined surfaces 202 can be completely fitted together.

[0025] Furthermore, the correction component includes a correction block 203, a correction shaft 2031 and a retaining groove 2032. The correction block 203 is arranged on the side of the fitting opening 201 away from the fitting inclined surface 202, the correction shaft 2031 is arranged in the middle of the correction block 203, and the retaining groove 2032 is arranged on the side wall of the correction shaft 2031. The correction block 203 is a protruding block protruding on one side of the fitting opening 201, the correction shaft 2031 is a circular shaft with a protruding part connected to the middle of the correction block 203, and the retaining groove 2032 is a plurality of triangular grooves on the side wall of the correction shaft 2031.

[0026] At the same time, when an error occurs, one side of the engaging block 204 will rest against the correction block 203, so that one side of the engaging block 204 will fit against the correction shaft 2031 protruding from the correction block 203, and then by continuously applying force to push it in, one side of the engaging block 204 will fit into the groove 2032 at different angles on the side wall of the correction shaft 2031, and then by applying force to push it in, the engaging block 204 will move around along the correction shaft 2031, and the correction shaft 2031 will also be driven to rotate, so that the engaging block 204 will be corrected due to the drive of the correction shaft 2031, so that it can adjust the error between it and the engaging opening 201, so that the two can cooperate and fit together for sealing and fire prevention, and prevent the bending of the engaging inclined surface 202 due to the error to form a gap.

[0027] The following is a specific implementation process of the utility model. First, when a fire occurs, the flame is blocked by closing the main body 1 to prevent the flame from spreading into the elevator. When the main body 1 is closed, the closing block 2 set on the opposite side will fit together with each other. When fitting together, the interlocking openings 201 and the interlocking blocks 204 arranged alternately on the two sides will cooperate and fit together, so that a tortuous seal is formed at the closed part of the main body 1, so that the flame cannot enter the elevator through the bend. When the interlocking block 204 is fitted into the interlocking opening 201, the vibration generated when the main body 1 moves may cause it to be unable to be accurately aligned, so that the fitting inclined surface 202 at the bend between the fitting opening 201 and the fitting block 204 will have a certain error. At this time, the fitting inclined surfaces 202 can be fitted together and move along the fitting inclined surfaces 202 when closing to align the fitting opening 201. 01 and the error between the engaging block 204 and the engaging block 204 is corrected to a certain extent, so that the fitting bevel 202 can be completely fitted together, and at the same time, when an error occurs, one side of the engaging block 204 will abut against the correction block 203, so that one side of the engaging block 204 will fit against the correction axis 2031 protruding from the correction block 203, and then by continuously applying force to push it in, one side of the engaging block 204 will be engaged into the abutting groove 2032 at different angles on the side wall of the correction axis 2031, and then by applying force to push it in, the engaging block 204 will be moved around along the correction axis 2031, and the correction axis 2031 will also be driven to rotate, so that the engaging block 204 will be corrected due to the drive of the correction axis 2031, so that it can adjust the error between it and the engaging opening 201, so that the two can cooperate and fit together for sealing and fire prevention, and prevent the bending of the fitting bevel 202 due to the error to form a gap.

[0028] 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.
