[0002] The fire door is a kind of door made of heat-resistant, flame-retardant or heat-absorbing material, which mainly blocks the fire from passing through the position of the door to achieve the purpose of protecting life and property safety. In the prior art, there is usually a gap between the door panel and the door frame, and between the door frame and the wall, so when a fire occurs, smoke will inevitably enter through these gaps. The prior art is not suitable for occasions where the degree of air purification is limited, such as purification workshops, shelters and container houses. To solve this problem, the industry has made improvements, for example, a fire door that can isolate smoke is disclosed in Chinese patent No. 202022341051.4, which states: including door frame, frame-shaped groove is opened in the rear side edge of the inner wall of the door frame, fire door body is hinged to the left side of the inner wall of the door frame, rectangular smoke inlet is opened in the lower left corner of the front side of the fire door body, fire-retardant rubber sealing rubber strip is provided on the outer side of the fire door body, rectangular recess is vertically opened on the rear side of the fire door body and close to the lower right corner, fixed plate is connected with the rectangular recess through screw thread, strip-shaped insert block is vertically provided on the side surface of the fixed plate, three installation plates are arranged at equal intervals on the outer side of the strip-shaped insert block, and each installation plate is provided with an air extractor.

[0003] The structure of the fire door is complex, and it relies on the air extractor and other power-consuming devices to complete the smoke isolation function. However, power failure may occur during a fire, which makes the fire door unable to continue to isolate smoke. There is an urgent need for a fire door that can isolate smoke or other gases without consuming energy. SUMMARY

[0008] In one preferred embodiment of the present disclosure, the secondary fixing member comprises a fifth fold, a sixth fold, a seventh fold, an eighth fold, a ninth fold and a secondary buffer fold, the fifth fold is at right angles to the sixth fold, the seventh fold is obliquely connected between the sixth fold and the eighth fold, the eighth fold is at right angles to the ninth fold, and the ninth fold is at an obtuse angle to the secondary buffer fold. After installation, the fifth fold abuts against the main fixing member, and the obliquely connected seventh fold and the sixth fold form a space between the door panel that can accommodate a sealing strip, and the obliquely arranged seventh fold can serve as a buffer mechanism when the main and secondary fixing members are pressed together.

[0009] In one preferred embodiment of the present disclosure, screw holes are provided in the first fold and the eighth fold, and bolts are installed in the screw holes.

[0010] In one preferred embodiment of the present disclosure, a sealing strip is provided at one or more places of the second fold, the fifth fold, the sixth fold, the seventh fold and the outer periphery of the door panel.

[0011] In one preferred embodiment of the present disclosure, the door panel comprises a main panel and a secondary panel, and a step is formed in the joint of the main panel and the secondary panel by being recessed inward, for installing a sealing strip.

[0012] In one preferred embodiment of the present disclosure, the main panel and the secondary panel of the door panel are filled with one of a fire-retardant material, a heat-insulating material or a heat-absorbing material.

[0013] Advantages of the present utility model

[0014] According to the present disclosure, the door frame is formed by the main fixing member and the secondary fixing member, not only forming a clamping covering for the hole in the wall body, but also greatly reducing the probability of smoke passing through the gap between the door frame and the wall body; the penetration direction of the bolt is horizontal, so that the fixed bolt is not visible in the closed state of the fireproof door, and the hidden bolt can reduce the probability of being damaged.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0021] Example 1

[0022] like Figures 1-3 As shown, a cleanroom fire door includes a main fixing member 2, a secondary fixing member 3, and a door panel 5, wherein the main fixing member 2 and the secondary fixing member 3 enclose the wall 1 and form a door frame for installing the door panel 5.

[0023] A bolt 4 passes through the main fixing member 2 and the secondary fixing member 3 and is fixed to the wall 1. The secondary fixing member 3 is connected to a door panel 5 by a hinge (conventional technology, not shown).

[0024] The main fixing component 2 includes a first fold 7, a second fold 8, a third fold 9, a fourth fold 10, and a main buffer fold 11. The first fold 7 is perpendicular to the second fold 8, the second fold 8 is perpendicular to the third fold 9, the third fold 9 is perpendicular to the fourth fold 10, and the fourth fold 10 is at an obtuse angle to the main buffer fold 11. The secondary fixing component 3 includes a fifth fold 12, a sixth fold 13, a seventh fold 14, an eighth fold 15, a ninth fold 16, and a secondary buffer fold 17. The fifth fold 12 is perpendicular to the sixth fold 13. The sixth fold 13 and the eighth fold 15 are connected at an angle by the seventh fold 14. The eighth fold 15 is perpendicular to the ninth fold 16, and the ninth fold 16 is at an obtuse angle to the secondary buffer fold 17. The first fold 7 and the eighth fold 15 are respectively provided with screw holes, and bolts 4 are installed in the screw holes. The second fold 8, the fifth fold 12, the sixth fold 13, the seventh fold 14, and the outer periphery of the door panel 5 are all provided with sealing strips (conventional technology, not shown). The door panel 5 includes a main panel and a secondary panel. A step 6 is recessed at the joint between the main panel and the secondary panel for installing a sealing strip. Flame-retardant material (conventional technology, not shown) is filled between the main panel and the secondary panel of the door panel 5.

[0025] Comparative Example 1

[0026] As shown in Figure 4 The two fixing members of the conventional pair of door frames are symmetrically arranged and the bolts are oppositely arranged.

[0027] Comparative Example 2

[0028] As a fire door capable of isolating smoke, patent No. 202022341051.4 shows that an exhaust fan is used to isolate smoke.

[0029] Comparison and Conclusion

[0030] Comparative Example 1 The bolt of the door panel is exposed after the door panel is closed, and is easy to be damaged by wind and rain, and is also easy to be damaged by impact. Comparative Example 2 is designed precisely, but relies too much on power-consuming devices such as exhaust fans, which cannot be used when power failure occurs due to fire. Example 1 has good smoke isolation effect through reasonable design, which is achieved without relying on power-consuming devices, and is suitable for use in clean rooms and other places, so it is named as a clean fire door.

[0031] Although the fire door according to the embodiments of the present disclosure has been described above, aspects of the present disclosure are not limited to the above-described embodiments, and the present disclosure can be implemented in various ways within the scope of the spirit of the present disclosure.
