DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Example 1
[0027] In this embodiment, if Figure 1-Figure 8 As shown, a fire door comprises a symmetrically arranged door panel 101, a handle is arranged on one side of the door panel 101, and the left and right sides of the door panel 101 are connected to the side panel 102, and the upper and lower ends of the door panel 101 are provided with a fixing plate 103, and one end of the fixing plate 103 is inserted into the interior of the two door panels 101, so as to limit the positional relationship between the door panel 101 and the side panel 102, and to facilitate the formation of a chamber, and a chamber for placing a fire protection layer 104 is formed between the door panel 101, the side panel 102 and the fixing plate 103, and the fire protection layer 104 is used to realize the fire door. The fireproof, waterproof and soundproof requirements also include a clamping mechanism 200 and a reinforcing mechanism 300. The clamping mechanism 200 is arranged between the fixing plate 103 and the door panel 101, and is used to limit the door panel 101 and the side panel 102. The reinforcing mechanism 300 is arranged at the diagonal positions around the door panel 101, and is used to increase the structural stability of the fire door. Before the fire door is used, first check whether the fire door can be used normally, then clamp the door panel 101 between the two side panels 102, and install the fixing plate 103 at the upper and lower ends of the door panel 101 through the clamping mechanism 200, so that the fire door enters a ready-to-use state;
[0028] Among them Figure 4 and Figure 5As shown, the clamping mechanism 200 includes a clamping slot 201 arranged on the opposite side of the two side plates 102, the clamping slot 201 is arranged inside the wedge block 106, and is convenient for accommodating the trapezoidal block 202. The trapezoidal block 202 is slidably connected inside the clamping slot 201, and the trapezoidal block 202 is connected to the inner wall of the clamping slot 201 through a spring 203. The spring 203 enables the trapezoidal block 202 to automatically return to its original position. Trapezoidal grooves 204 are symmetrically arranged on both sides of the fixing plate 103, and the positions of the clamping slot 201 and the trapezoidal groove 204 correspond to each other. The inner wall of the clamping slot 201 is fixed A limit block 205 is provided to limit the sliding distance of the trapezoidal block 202 to prevent the trapezoidal block 202 from being unable to stably slide into the slot 201. After the door panel 101 and the side panel 102 are connected, the fixed plate 103 is pushed toward the inside of the door panel 101, so that the trapezoidal block 202 is subjected to pressure and moves into the slot 201. When the fixed plate 103 reaches the corresponding position, due to the elastic effect of the spring 203, the trapezoidal block 202 is connected into the trapezoidal slot 204, thereby performing a limit operation on the fixed plate 103 and the side panel 102.
[0029] Among them Figure 2 and Figure 8 As shown, the reinforcing mechanism 300 includes symmetrically arranged reinforcing blocks 301 to prevent the fire door from structural deformation and to block the gap between the plates. A placement groove 302 matching the shape of the door plate 101 is provided inside the reinforcing block 301. A latch hole is provided on the surface of the reinforcing block 301. A latch 303 is connected inside the latch hole. The latch 303 can restrict the fire door through the latch hole. One end of the latch 303 penetrates the fire protection layer 104 and extends to the inside of the placement groove 302. A circular hole is provided at the other end of the latch 303. The circular hole ensures the normal use of the fire door, so that the fixing rod 304 can pass through the circular hole and then be plugged into the two latches 303, so that the two reinforcing blocks 301 on the same horizontal line can be restricted. A fixing rod 304 is provided inside the circular hole. A nut can be provided on one side of the fixing rod 304 to prevent the fixing rod 304 from falling off.
[0030] Among them Figure 6 As shown, the door panel 101 is symmetrically provided with extension parts 105 on both sides, which are convenient for clamping with the side panels 102, thereby increasing the overall practicality of the fire door;
[0031] Among them Figure 6 and Figure 7As shown, the side panel 102 is set to be U-shaped, and a wedge block 106 is connected to one side of the side panel 102 to fix the left and right sides and the front and rear sides of the door panel 101. An extension groove 107 is provided between the wedge block 106 and the side panel 102. The extension groove 107 is adapted to the size specification of the extension portion 105, which is convenient for the installation and docking between the adjacent door panels 101 and the side panels 102, and the upper and lower sides of the door panels 101 are fixed, which is convenient for the plane layout of the entire fire door, ensuring the stability of the docking between adjacent panels, and reducing the docking gap between adjacent panels;
[0032] Among them Figure 2 As shown, a notch 108 is provided at the connection between the side plate 102 and the fixing plate 103, and the notch 108 is consistent with the size specification of the reinforcing block 301. Through the cooperation between the notch 108 and the reinforcing block 301, the firmness between the side plate 102 and the fixing plate 103 can be improved;
[0033] Among them Figure 5 As shown, the trapezoidal block 202 is slidably connected with the trapezoidal groove 204, and the size specifications of the trapezoidal groove 204 and the trapezoidal block 202 are adapted to ensure the normal use of the fire door, and the practicality is good;
[0034] Example 2
[0035] The difference from Example 1 is that Figure 4 As shown, the fire protection layer 104 includes a waterproof board, a hollow board, a foam insulation layer and a sponge sound insulation layer, which are arranged in sequence from the outside to the inside. A reinforcement plate is provided between the foam insulation layer and the sponge sound insulation layer, so as to facilitate filling some sound insulation, heat insulation, fireproof and waterproof materials into the interior of the fire door according to the on-site use requirements, thereby reducing the weight of the fire door and reducing transportation costs.
[0036] When in use, the user slides the extension portion 105 of the door panel 101 into the extension groove 107 of the side panel 102 so that the wedge block 106 is engaged with the extension portion 105, thereby improving the installation stability of the fire door. The user engages the fixing plate 103 between the door panel 101 and the side panel 102, and the door panel 101, the side panel 102, and the fixing plate 103 can be fixed through the clamping mechanism 200, thereby achieving a splicing effect without the need for screws, which is convenient for quick installation and has good practicality.
[0037] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
