[0002] The advantages of heat-insulating and noise-reducing wooden security doors mainly include excellent sound insulation, natural and environmentally friendly materials, beautiful appearance, excellent durability and stability.

[0003] Soundproof doors are devices specially designed to isolate the impact of noise. Their average sound insulation can reach 39dB, and their sound insulation can reach over 55dB. They can effectively reduce the impact of external noise on the indoor environment. They are suitable for places that need to maintain a relatively quiet environment, such as radio stations, studios, offices, conference rooms, hospital studios, etc.

[0004] There is a gap between the bottom of the heat-insulating and noise-reducing door in the prior art and the ground, which has two disadvantages:

[0005] 1. Affecting the sound insulation and thermal insulation effects: If the gap at the bottom of the door is too large, it will affect the indoor sound insulation and thermal insulation effects, making it easier for external sounds to enter the room, and the indoor temperature will also be more easily affected by the external environment;
