[0018] like Figure 1-3 As shown, the utility model provides a steel core door leaf plate, including a rectangular metal frame 1, a first wooden square 4 connected to both ends of the metal frame 1 and a second wooden square 5 connected to both sides of the metal frame 1, the outer wall of the metal frame 1 is fixedly connected with a plywood 7, and a decorative veneer is attached to the plywood 7, the first wooden square 4 and the second wooden square 5 are both located at the edge between the two plywoods 7, and a filler is arranged in the metal frame 1.

[0019] The door body 9 adopts a metal frame 1 structure, and the metal frame 1 is a rectangular frame. The first wooden square 4 and the second wooden square 5 are locked around the metal frame 1 by bolts, and the bolt heads are located inside the metal frame 1, so that the surface of the door body 9 is smooth and more integrated, thereby ensuring the quality of the steel core door leaf plate.

[0020] By fixing the clamping plate 7 on the metal frame 1 and filling and compacting the filling inside the metal frame 1, the clamping plate 7 can be stably supported and will not deform during long-term use. The ends of the first wooden square 4 and the second wooden square 5 are both inclined cuts. After the first wooden square 4 and the second wooden square 5 are installed on the metal frame 1, the ends of the first wooden square 4 and the second wooden square 5 will not protrude, so that the side of the door body 9 is flat.

[0021] After the installation of the plywood 7 is completed, the decorative veneer is adhered to the plywood 7 by means of an adhesive, and then heat-pressed to ensure tight adhesion.

[0022] like Figure 1 As shown. The ends of the first wood square 4 and the second wood square 5 are in contact, and the contact ends of the first wood square 4 and the second wood square 5 are at an angle. The setting of the angle makes the interface between the first wood square 4 and the second wood square 5 smooth, and this docking form can avoid the existence of protruding parts on the side wall after the door body 9 is assembled, ensuring the aesthetics.

[0023] like Figure 1 The inner wall of the metal frame 1 is provided with first connection holes 3 , which are distributed on each side of the metal frame 1 and are evenly spaced, and nuts matching the first connection holes 3 are embedded in the first wooden square 4 and the second wooden square 5 .

[0024] The bolt passes through the first connecting hole 3 and connects to the nut in the first wooden square 4 or the second wooden square 5, thereby locking the first wooden square 4 or the second wooden square 5 on the metal frame 1, thereby preventing the metal parts from being exposed.

[0025] like Figure 1 and Figure 2 The top and bottom of the metal frame 1 are both provided with second connection holes 6 , the clamping plate 7 is provided with countersunk holes adapted to the second connection holes 6 , and the second connection holes 6 and the first connection holes 3 are staggered.

[0026] The countersunk holes on the clamping plate 7 are used to accommodate the bolt heads, ensuring that the surface of the clamping plate 7 is in a flat state after installation, thereby improving the flatness of the veneer installation.

[0027] like Figure 1 The metal frame 1 is fixed with adapter blocks on both sides, the second wooden square 5 is provided with adapter grooves matching with the adapter blocks, the adapter blocks are provided with threaded holes for connecting hinges, and the back of the second wooden square 5 corresponding to the adapter grooves is provided with threaded hole position marks.

[0028] The steel core door leaf plate adopts the form of reserved hinge installation holes. The screws are directly screwed in along the hole marks to lock the metal plate of the hinge on the second wooden square 5. The setting of the adapter block makes the hinge installation stronger and is not easy to damage the wood on the edge of the leaf plate during use.

[0029] like Figure 1 and Figure 2 As shown. A crossbar 2 is provided in the middle of the metal frame 1, and an adapter platform 8 corresponding to the inner cavity of the metal frame 1 is provided on the clamping plate 7, and the adapter platform 8 is a boss structure. The matching form of the adapter platform 8 and the boss not only facilitates the installation and positioning of the clamping plate 7, but also can further squeeze the filler.
