[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1 The utility model provides a technical solution for the structure of a fireproof door panel: a fireproof door panel structure, including a door handle 2, and a fireproof material outer frame 1 is arranged inside the door handle 2. The fireproof material outer frame 1 plays a major fire prevention and supporting role. It is made of a material with good fireproof performance and can effectively block the invasion of flames and high temperatures when a fire occurs. An internal supporting door panel 3 is arranged inside the fireproof material outer frame 1, which provides additional structural support for the entire door panel and enhances the strength and stability of the door panel. The door handle 2 is fixedly connected to the middle part of the left side of the fireproof material outer frame 1 to facilitate people to open and close the door.
[0024] See also Figure 2The fireproof material outer frame 1 includes two vertical support fixing seats 11 parallel to each other, and the left and right ends of the opposite sides of the vertical support fixing seats 11 are commonly fixedly connected with lateral fireproof material door panels 13, and the front and rear ends of the opposite sides of the vertical support fixing seats 11 are commonly fixedly connected with horizontal fireproof material door panels 12. The right end of the horizontal fireproof material door panel 12 is rotatably connected with a plurality of reinforcement components 14, and the plurality of reinforcement components 14 are evenly distributed on the right end of the horizontal fireproof material door panel 12. The right side fireproof material door panel 13 is provided with a plurality of fixing grooves that can pass through the reinforcement components 14 at the corresponding positions of the plurality of reinforcement components 14. The two vertical support fixing seats 11 are sleeved on the upper and lower ends of the internal support door panel 3.
[0025] Two vertical support fixing seats 11 parallel to each other provide the main longitudinal support and fixing basis for the entire outer frame. The lateral fireproof material door panels 13 at the left and right ends of the opposite sides of the vertical support fixing seats 11 and the horizontal fireproof material door panels 12 at the front and rear ends together constitute a closed frame structure, which can effectively block the invasion of flames and high temperatures from the side and front and rear directions when a fire occurs. The reinforcement component 14 plays a role in strengthening and fixing the entire outer frame structure.
[0026] See also Figure 3 The reinforcement component 14 includes a rotating block 141, which is fixedly connected to a rotating column 142 through the upper and lower parts. The rotating column 142 is rotatably connected to the rear end of the horizontal fire-proof material door panel 12. The end of the rotating block 141 away from the horizontal fire-proof material door panel 12 is fixedly connected to a threaded fixing column 143, and the threaded fixing column 143 passes through the fixing groove and is threadedly connected to a fixing nut 144.
[0027] See also Figure 3 , the diameter of the fixing nut 144 is larger than the fixing groove.
[0028] The rotating block 141 is rotatably connected to the rear end of the horizontal fireproof material door panel 12 through the rotating column 142, so that the rotating block 141 can rotate relative to the horizontal fireproof material door panel 12. When it is necessary to fix the right side fireproof material door panel 13, the threaded fixing column 143 is rotated through the fixing groove, and then the fixing nut 144 is used to thread the threaded fixing column 143. By rotating the fixing nut 144 to shorten the distance between the threaded fixing column 143 and the fixing nut 144, the lateral fireproof material door panel 13 is tightened and fixed.
[0029] See also Figure 4The internal supporting door panel 3 includes a door panel supporting sleeve 31, and a plurality of sleeved combined door panels 32 are arranged on the right side of the door panel supporting sleeve 31. The two adjacent sleeved combined door panels 32 are sleeved and connected to each other. The leftmost sleeved combined door panel 32 is sleeved on the end of the door panel supporting sleeve 31, and the right side of the rightmost sleeved combined door panel 32 is sleeved and connected with a door panel supporting sleeve head 33. The door panel supporting sleeve head 33, the sleeved combined door panel 32 and the top of the door panel supporting sleeve 31 are jointly sleeved on the inner side of the vertical support fixing seat 11.
[0030] The door panel support sleeve 31 serves as the starting end, providing basic support and connection points for the entire internal support door panel 3. Several nested combined door panels 32 are nested and connected to each other. This nested connection method enables each door panel to be tightly combined, thereby enhancing the overall structural strength. The leftmost nested combined door panel 32 is nested on the door panel support sleeve 31, and so on, realizing a connection from left to right. The right side of the rightmost nested combined door panel 32 is nested and connected to the door panel support sleeve head 33, which plays a role in finishing and reinforcement.
[0031] See also Figure 5 The sleeved combined door panel 32 includes a supporting door frame 322, a triangular sleeve groove is opened at the left end of the supporting door frame 322, the upper and lower ends of the sleeved combined door panel 32 are fixedly connected with trapezoidal synchronous fixed edges 321, and the right end of the supporting door frame 322 is fixedly connected with a supporting inserted edge 323 that is the same as the sleeve groove.
[0032] The triangular sleeve groove opened at the left end of the supporting door frame 322 cooperates with the supporting ridge 323 at the right end. When two adjacent sleeve combination door panels 32 are connected, the supporting ridge 323 of one door panel is inserted into the sleeve groove of the other door panel to realize the sleeve connection. The trapezoidal synchronous fixed ridge 321 fixedly connected at the upper and lower ends, on the one hand, enhances the structural strength of the sleeve combination door panel 32 itself, and on the other hand, when multiple sleeve combination door panels 32 are assembled and installed, it helps to maintain the overall flatness and stability, ensuring that the door panels will not be misaligned or deformed during use.
[0033] See also Figure 5 The number of supporting ribs 323 is one more than that of supporting door frames 322 , and the left end of the extra supporting rib 323 is fixedly connected to the right end of the door panel supporting sleeve 31 , and the left end of the door panel supporting sleeve 33 is also provided with a sleeve groove.
[0034] Working principle:
[0035] First, during installation, place a vertical support fixing seat 11 at the bottom, and fix the lateral fireproof material door panel 13 and the horizontal fireproof material door panel 12 through the reinforcement component 14 to form a fireproof material outer frame 1. Then, starting from the left side, put the leftmost sleeved combined door panel 32 on the door panel support sleeve 31, and then successively sleeve the adjacent sleeved combined door panels 32 with each other through the sleeve groove and the support insert 323. The rightmost sleeved combined door panel 32 is sleeved with the connecting door panel support sleeve 33, and then the internal support door panels 3 are removed and inserted into the fireproof material outer frame 1 through the vertical support fixing seat 11. Finally, another vertical support fixing seat 11 is used to seal the fireproof material outer frame 1 to complete the assembly.
[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
