Description

Technical Field

[0001] This utility model relates to the field of solid wood composite door installation technology, specifically a crack-resistant solid wood composite door. Background Technology

[0002] Crack-resistant solid wood composite doors are door products made by combining high-quality solid wood materials with other auxiliary materials. Their core feature is the effective prevention of cracking. These doors typically use advanced technology to combine solid wood materials with more stable materials (such as MDF, plywood, etc.), which not only maintains the natural beauty and texture of solid wood, but also significantly improves the stability and durability of the door.

[0003] A search revealed a crack-resistant solid wood composite door disclosed in Chinese Utility Model Patent Publication No. CN215332342U. The door includes a composite door frame with T-shaped limiting grooves on both sides. T-shaped sliders are slidably connected to the top of the inner walls of the two T-shaped limiting grooves. The middle of one side of each T-shaped slider is rotatably connected to one end of the outer wall of a first connecting post. The other ends of the outer walls of the two first connecting posts are rotatably connected to one end of each side of the solid wood composite door panel. This utility model, by activating an electric sliding rod, lifts and rotates two L-shaped transmission plates, causing the solid wood composite door panel to slide within the T-shaped limiting grooves via the two T-shaped sliders. The door panel slides to the top of the composite door frame, thus opening the solid wood composite door. This solves the problem of difficulty in opening crack-resistant solid wood composite doors when residential passageways are blocked by objects, hindering users' access to the door.

[0004] However, this device often lacks sound insulation. When in use, due to its poor sound insulation effect, outdoor noise, such as vehicle traffic and crowd noise, can easily enter the room, making the living or working environment noisy and affecting people's normal life and work efficiency. Moreover, this device also lacks flame retardant function. When in use, the lack of flame retardant function means that in the event of a fire, the door may burn faster and cannot effectively stop the spread of fire, which will greatly increase the degree of damage caused by the fire and the risk of casualties. Utility Model Content

[0005] The purpose of this utility model is to provide a crack-resistant solid wood composite door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crack-resistant solid wood composite door includes a door panel, a composite board fixedly connected inside the door panel, a sound insulation board fixedly connected to one side of the composite board, rock wool fixedly connected inside the sound insulation board, a sealing strip fixedly connected to one side of the door panel, a flame-retardant board fixedly connected to one side of the sound insulation board, glass fiber fixedly connected inside the flame-retardant board, and a fire-retardant coating fixedly connected to the surface of the door panel.

[0008] Preferably, a hinge is fixedly connected to one side of the door panel, and a fixing bolt is threaded to one end of the hinge.

[0009] Preferably, a peephole is fixedly connected to the upper surface of the door panel, and a doorbell is fixedly connected to one side of the peephole.

[0010] Preferably, a handle is fixedly connected to the middle of the door panel, and a door lock is fixedly connected to the bottom of the handle.

[0011] Preferably, a mounting rod is fixedly connected to the bottom of the door panel, and a magnetic head is fixedly connected to one end of the mounting rod.

[0012] Preferably, one side of the hinge is rotatably connected to a door frame, and one side of the door frame is provided with a latch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This crack-resistant solid wood composite door, in use, utilizes sound insulation boards, rock wool, and sealing strips. The door panel's interior consists of composite boards and sound insulation boards, with the sound insulation boards filled with rock wool. The rock wool-filled sound insulation boards have excellent sound absorption properties; when sound waves encounter the rock wool-filled sound insulation boards, most of the energy is converted into heat energy, significantly reducing the energy of the sound waves passing through the door panel and achieving a good sound insulation effect. Furthermore, the rock wool filling increases the thickness and density of the door panel, making it more stable and reducing deformation caused by external forces, such as cracking. This stability helps extend the service life of the door panel. Sealing strips are installed around the perimeter of the door panel, effectively filling the gaps between the door frame and the door panel, preventing sound waves from overflowing or entering through these gaps, thus achieving a sound insulation effect.

[0015] 2. This crack-resistant solid wood composite door utilizes a combination of flame-retardant board, fiberglass, and fire-retardant coating. The flame-retardant board is installed inside the door panel, and the fiberglass within it enhances the flame-retardant effect, slowing the spread of fire in high-temperature environments. The fire-retardant coating on the surface of the door panel releases water vapor or forms a carbonized layer when exposed to high temperatures, thus isolating oxygen and effectively inhibiting the spread of fire, thereby achieving a flame-retardant effect.
