DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope protected by the utility model.

[0022] The specific embodiments of the utility model will be described below in combination with the drawings:

[0023] As Figures 1-7 shown, a sealed plate type smoke exhaust port, including air pipe 1, one end of air pipe 1 is equipped with air inlet 11, the other end is equipped with air outlet 12. Air inlet 11 is equipped with sealing plate 2. The both sides of sealing plate 2 are equipped with spring rotating shaft 21, and air pipe 1 is equipped with the positioning groove 15 matched with spring rotating shaft 21. Spring rotating shaft 21 is equipped with clockwork 211 spring, and the elastic potential energy of clockwork 211 spring is used to accumulate as the driving power of the rotation of sealing plate 2, and sealing plate 2 is rotatably connected with air pipe 1 through the cooperation of spring rotating shaft 21 and positioning groove 15. Air pipe 1 is equipped with elastic clamping mechanism 3 on the side corresponding to sealing plate 2 at 90 ° of the plane where elastic clamping mechanism 3 is located, and air pipe 1 is equipped with detachable clamping block 4 corresponding to sealing plate 2 on the side at 90 ° of the plane.

[0024] Under normal circumstances, sealing plate 2 is attached to elastic clamping mechanism 3, and air inlet 11 is completely closed. After unlocking elastic clamping mechanism 3, spring rotating shaft 21 drives sealing plate 2 to rotate 90 ° to attach to clamping block 4, at this time, the opening degree of air inlet 11 is maximum, and the ventilation effect is best. If the temperature rises due to fire, the clamping block 4 melts, and the sealing plate 2 continues to rotate 90 ° to attach to the elastic clamping mechanism 3 under the action of the spring rotating shaft 21, and the sealing plate 2 reseals the air inlet 11 to prevent the deterioration of the fire. Air pipe 1 is equipped with arc cavity 13 matched with the edge of sealing plate 2, and arc cavity 13 provides enough space for the rotation of sealing plate 2. The inner wall of arc cavity 13 is equipped with sealing pad 131 attached to the edge of sealing plate 2. Sealing pad 131 improves the sealing property of sealing plate 2 to air inlet 11.

[0025] The wind pipe 1 is provided with a sliding groove 132 corresponding to the elastic clamping mechanism 3, and the elastic clamping mechanism 3 moves along the sliding groove 132. The elastic clamping mechanism 3 comprises an integrated moving block 31, a guide rod 32 and a pull ring 33, the moving block 31 is located in the inside of the wind pipe 1, the pull ring 33 is located outside the wind pipe 1, the guide rod 32 penetrates through the bottom of the sliding groove 132 and is provided with a compression spring 321, one end of the compression spring 321 is in contact with the moving block 31, and the other end is in contact with the bottom of the sliding groove 132. The pull ring 33 is pulled from the outside of the wind pipe 1 to make the moving block 31 move downward along the guide rod 32, so that the sealing plate 2 is unlocked, and then the pull ring 33 is released, and the moving block 31 automatically rebounds to the original position under the action of the compression spring 321, so as to prepare for clamping the sealing plate 2 again.

[0026] The clamping block 4 comprises an integrated contact plate 41 and a positioning block 42, one side of the contact plate 41 is in contact with one side of the sealing plate 2, and the wind pipe 1 is provided with a positioning groove 15 matched with the positioning block 42. Through the cooperation of the positioning block 42 and the positioning groove 15, the clamping block 4 is assembled to the side wall of the wind pipe 1. The contact plate 41 blocks the sealing plate 2 from continuing to rotate. The contact plate 41 is provided with a reinforcing rib 411 on the side away from the sealing plate 2, and the reinforcing rib 411 can improve the strength of the contact plate 41 without increasing the thickness of the contact plate 41, so as to prevent the contact plate 41 from being broken in the collision with the sealing plate 2. The thin contact plate 41 is convenient for melting and breaking in time at high temperature, so that the sealing plate 2 can seal the air inlet 11 in time. The side, away from the contact plate 41, of the positioning block 42 is provided with a protrusion 421, and the positioning groove 15 is provided with a through hole 151 matched with the protrusion 421. The through hole 151 is convenient for discharging the deformed and failed clamping block 4, and facilitates replacement of the new clamping block 4.

[0027] The working principle of the specific embodiment of the utility model is as follows: when the fire occurs, the moving block 31 is pulled down by manually pulling the pull ring 33, the sealing plate 2 is rotated by 90 degrees to be attached to the clamping block 4 under the action of the spring rotating shaft 21, at this time, the opening degree of the air inlet 11 is maximum, and the ventilation effect of the wind pipe 1 is best; the pull ring 33 is released, and the moving block 31 rebounds to the original position under the action of the compression spring 321. As the fire becomes larger, the temperature rises, the clamping block 4 melts, and the sealing plate 2 continues to rotate to be attached to the moving block 31 under the action of the spring rotating shaft 21, at this time, the sealing plate 2 reseals the air inlet 11, preventing the fire from continuing to worsen.
