[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 highly sealed fireproof wooden door comprises a wooden door 1, a door frame 2 is arranged around the wooden door 1, an engaging groove 101 is arranged on one side of the upper and lower ends of the wooden door 1, sealing plates 203 are arranged on the upper and lower sides of the middle inner wall of the door frame 2, the sealing plates 203 cooperate with the engaging groove 101, and the upper and lower sides of the middle inner wall of the door frame 2 are connected with extrusion components, the extrusion components are attached to one side of the bottom of the wooden door 1, and the extrusion components are lifted and lowered along the groove. The sealing plate 203 is a plate with rectangular protrusions on both sides of the middle inner wall of the door frame 2, and the sealing plate 203 also includes a limiting groove 2031 and a limiting block 2032. The limiting groove 2031 is arranged at the top of the sealing plate 203, and the limiting block 2032 is arranged in the middle of the limiting groove 2031. The limiting block 2032 is a trapezoidal block connected to the limiting groove 2031 through a bottom spring, and the limiting block 2032 cooperates with a groove arranged at the top of the middle of the engaging groove 101.
[0023] First, the room is sealed by closing the wooden door 1 in the door frame 2. At the same time, when the wooden door 1 is closed, the engaging grooves 101 at the upper and lower ends of the wooden door 1 will cooperate and engage with the sealing plate 203 on the inner wall of the door frame 2, so that the upper and lower ends of the wooden door 1 will be tightly embedded and sealed with the sealing plate 203. At the same time, when the engaging groove 101 cooperates with the sealing plate 203, it will squeeze the limit block 2032 on the top of the sealing plate 203. Through the trapezoidal setting of the limit block 2032, it will shrink into the limit groove 2031 when the force is applied against the inclined surface. Then, after the engaging groove 101 and the sealing plate 203 are fully matched, the limit block 2032 will be reset by the spring and engaged into the groove at the top of the middle part of the limit groove 2031, so that the connection between the two is more stable and a certain gap will not be easily generated due to shaking.
[0024] Furthermore, the extrusion assembly also includes an extrusion block 201 and a shrinkage groove 202. The shrinkage groove 202 is a groove arranged on the upper and lower sides of the middle inner wall of the door frame 2. The extrusion block 201 is a trapezoidal block connected to the shrinkage groove 202 by a spring. A certain gap is left between the upper and lower sides of the middle inner wall of the door frame 2 and the upper and lower sides of the wooden door 1.
[0025] At the same time, when the wooden door 1 is closing, it will abut against the inclined surface of the extrusion block 201, and then by applying force, the extrusion block 201 will shrink into the shrinkage groove 202, so that the wooden door 1 can be closed smoothly. At the same time, after the wooden door 1 passes through the extrusion block 201, the extrusion block 201 will be reset by the spring, so that the inclined surface on the other side will abut against one side of the wooden door 1, and then through the elasticity of the spring at the bottom of the extrusion block 201, a certain extrusion force will be generated, so that the wooden door 1 will be pushed in the closing direction along the inclined surface by itself, and then finally, the gaps on the upper and lower sides of the wooden door 1 and the door frame 2 will make the extrusion block 201 always generate extrusion force, so that the wooden door 1 will generate a certain force to abut against the sealing plate 203. Through this extrusion force, the wooden door 1 will be forced to fit the sealing plate 203 more closely, so that the sealing effect is better, and there will be no gaps that cannot be closed due to shaking, so that when the fire door is on fire indoors, the fire will not spread quickly due to ventilation due to the gaps.
[0026] The following is a specific implementation process of the present invention. First, the wooden door 1 is closed in the door frame 2 to seal the room. At the same time, when the wooden door 1 is closed, the engaging grooves 101 at the upper and lower ends of the wooden door 1 will cooperate and engage with the sealing plate 203 on the inner wall of the door frame 2, so that the upper and lower ends of the wooden door 1 will be tightly embedded and sealed with the sealing plate 203. At the same time, when the engaging grooves 101 cooperate with the sealing plate 203, they will squeeze the limiting block 2032 at the top of the sealing plate 203. Through the trapezoidal setting of the limiting block 2032, it will shrink into the limiting groove 2031 when the force is applied against the inclined surface. Then, after the engaging grooves 101 and the sealing plate 203 are fully matched, the limiting block 2032 will be reset by the spring and engaged with the groove at the top of the middle part of the limiting groove 2031, so that the connection between the two is more stable, and a certain gap will not be easily generated due to shaking. At the same time, when the wooden door 1 is closed, it will press against the squeezed The inclined surface of the pressing block 201 will then be contracted into the contraction groove 202 by applying force, so that the wooden door 1 can be closed smoothly. At the same time, after the wooden door 1 passes through the extrusion block 201, the extrusion block 201 will be reset by the spring, so that the inclined surface on the other side will be against one side of the wooden door 1, and then through the elasticity of the spring at the bottom of the extrusion block 201, a certain extrusion force will be generated, so that the wooden door 1 will be pushed in the closing direction along the inclined surface by itself, and then finally, the gap between the wooden door 1 and the upper and lower sides of the door frame 2 will allow the extrusion block 201 to always generate an extrusion force, so that the wooden door 1 will generate a certain force to press against the sealing plate 203. Through this extrusion force, the wooden door 1 will be forced to fit the sealing plate 203 more closely, so that the sealing effect is better, and there will be no gaps that cannot be closed due to shaking, so that when the fire door is on fire indoors, the fire will not spread quickly due to ventilation due to the gaps.
[0027] 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.
