Description

Technical Field

[0001] This application relates to the field of entrance door technology, and in particular to a high-efficiency fireproof, soundproof and energy-saving entrance door. Background Technology

[0002] The entrance door, also known as the front door or main door, is the primary barrier connecting a home, commercial space, or other space to the external environment. It is usually installed at the building entrance and directly connects to the corridor, courtyard, or outdoor area. It is the first line of defense for ensuring indoor security and privacy. As people's requirements for living quality have increased, the performance requirements for entrance doors have evolved from simply preventing theft to a comprehensive approach including fire prevention, sound insulation, and energy saving, becoming one of the important indicators for measuring living comfort and security.

[0003] However, current entry doors on the market are prone to collisions between the door leaf and the door frame, and their poor sealing leads to noise transmission. In addition, to accommodate differences in floor flatness and the need for door opening and closing, a 5-10mm gap is usually left between the bottom of the door and the ground, which makes it difficult to block airborne sound transmission and affects the sound insulation effect, failing to meet users' needs for a quiet living environment. Therefore, to solve the above problems, we provide a high-efficiency fireproof, soundproof, and energy-saving entry door. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency fireproof, soundproof, and energy-saving entrance door to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions: A high-efficiency fireproof, soundproof, and energy-saving entrance door includes a door leaf, an external door frame, one side of the door leaf being hinged to one side of the door frame via a hinge, a magnetic sound-absorbing strip on one side of the door leaf, PU foam on one side of the door frame, an aluminum alloy frame fixedly embedded in the bottom surface of the door leaf, a set of tension springs fixedly connected to the inner top wall of the aluminum alloy frame, an aluminum alloy support plate fixedly connected to the bottom ends of the set of tension springs, a silicone pad fixedly connected to the bottom surface of the aluminum alloy support plate, a lower sliding plate fixedly connected to the upper surface of the aluminum alloy support plate, an upper sliding plate fixedly connected to one side of the lower sliding plate, and a circular impact rod fixedly connected to one side of the upper sliding plate.

[0006] Preferably, an impact plate is fixedly embedded on one side of the door frame, and one end of the circular impact rod contacts one side of the impact plate.

[0007] Preferably, a limiting slide is fixedly connected to the inner wall of the aluminum alloy frame, the outer surface of the circular impact rod is slidably connected to the inner wall of the limiting slide, and one side of the upper sliding plate is slidably connected to the inner wall of the aluminum alloy frame.

[0008] Preferably, a limiting seat is fixedly connected to the inner top wall of the aluminum alloy frame, a limiting block is fixedly connected to the upper surface of the aluminum alloy support plate, and the outer surface of the limiting block is slidably connected to the inner wall of the limiting block.

[0009] Preferably, the inner wall of the door leaf is fixedly connected with a grid-shaped solid wood keel frame, the door leaf adopts a rigid-flexible composite core of graphite homogeneous board and Class A fireproof functional board, and the edges of the door frame and the door leaf are inlaid with intumescent fireproof strips.

[0010] Preferably, a first groove and a second groove are respectively provided on one side of the door frame and one side of the door leaf. One end of the magnetic sound-absorbing strip is engaged inside the first groove, and one side of the PU sponge is engaged inside the second groove. A TPE skeleton is fixedly embedded inside the PU sponge, and a magnetic strip is fixedly embedded on one side of the PU sponge. The magnetic sound-absorbing strip is in contact with one side of the magnetic strip.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This highly efficient fireproof, soundproof, and energy-saving entrance door uses magnetic sound-absorbing strips and PU sponge to prevent direct contact and collision between the door leaf and the door frame, reducing impact noise when opening and closing the door. At the same time, the magnetic structure fits tightly, filling the gap between the two and forming a sealing barrier, improving the sealing performance of the connection between the door leaf and the door frame. This solves the noise transmission problem caused by unreasonable assembly gaps in the previous technology and enhances the sound insulation performance of the entrance door.

[0012] 2. This highly efficient fireproof, soundproof, and energy-saving entrance door features a lift-up sealing structure that enables automatic sealing at the bottom of the door. When the door is closed, a circular impact rod triggers an aluminum alloy support plate, causing a silicone pad to extend from the aluminum alloy frame and fit tightly against the ground, sealing the gaps at the bottom of the door and blocking airborne sound transmission. When the door is opened, a spring returns to its original position, causing the silicone pad to retract automatically without affecting the normal opening and closing of the door. No manual operation is required, thus improving the sound insulation effect. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-6 This utility model provides a high-efficiency fireproof, soundproof, and energy-saving entrance door technical solution: A high-efficiency fireproof, soundproof, and energy-saving entrance door includes a door leaf 1 and a door frame 2. The surfaces of both the door leaf 1 and door frame 2 are coated with a three-layer environmentally friendly water-based paint system. The topcoat contains nano-alumina wear-resistant particles and is treated with electrostatic spraying and high-temperature curing processes to form a high-hardness, scratch-resistant, UV-resistant, and stain-resistant protective paint surface structure, improving surface durability. The substrate of the door leaf 1 undergoes high-temperature steaming degreasing, vacuum pressure impregnation with a moisture-proofing agent, and constant temperature and humidity balancing curing treatment. Combined with a surface-sealed waterproof paint film, this reduces the moisture absorption of the wood and enhances the stability of the door leaf in humid environments. One side of the door leaf 1 is hinged to one side of the door frame 2. A magnetic sound-absorbing strip 6 is installed on one side of the door leaf 1. One side of the door is provided with PU sponge 8. The bottom surface of the door leaf 1 is fixedly inlaid with an aluminum alloy frame 5. A set of tension springs 12 is fixedly connected to the inner top wall of the aluminum alloy frame 5. The bottom ends of the set of tension springs 12 are fixedly connected to an aluminum alloy support plate 4. A silicone pad 3 is fixedly connected to the bottom surface of the aluminum alloy support plate 4. A lower sliding plate 16 is fixedly connected to the upper surface of the aluminum alloy support plate 4. An upper sliding plate 17 is fixedly connected to one side of the lower sliding plate 16. A circular impact rod 19 is fixedly connected to one side of the upper sliding plate 17. The circular impact rod 19 triggers the aluminum alloy support plate 4 to drive the silicone pad 3 to extend out of the aluminum alloy frame 5 and fit tightly against the ground, which can seal the gap at the bottom of the door and block the air transmission of sound. In addition, both the door leaf 1 and the door frame 2 are made of fireproof materials.

[0018] In this embodiment, an impact plate 15 is fixedly embedded on one side of the door frame 2, and one end of the circular impact rod 19 contacts one side of the impact plate 15. A limiting slide 18 is fixedly connected to the inner wall of the aluminum alloy frame 5. The outer surface of the circular impact rod 19 is slidably connected to the inner wall of the limiting slide 18. One side of the upper sliding plate 17 is slidably connected to the inner wall of the aluminum alloy frame 5. A limiting seat 13 is fixedly connected to the inner top wall of the aluminum alloy frame 5. A limiting block 14 is fixedly connected to the upper surface of the aluminum alloy support plate 4. The outer surface of the limiting block 14 is slidably connected to the inner wall of the limiting block 14. Specifically, the impact plate 15 can contact one end of the circular impact rod 19, which can provide force support for the triggering of the door bottom sealing structure and prevent the door frame 2 from being directly damaged by impact. The limiting slide 18 can limit the sliding trajectory of the circular impact rod 19 to ensure its stable movement. The sliding cooperation between the limiting seat 13 and the upper limiting block 14 of the aluminum alloy support plate 4 can limit the lifting range of the aluminum alloy support plate 4 to prevent it from deviating and ensure that the silicone pad 3 is in contact with the ground.

[0019] In this embodiment, a grid-shaped solid wood keel frame 11 is fixedly connected to the inner wall of the door leaf 1. The door leaf 1 uses a rigid-flexible composite core of graphite homogeneous board and Class A fireproof functional board. Expandable fireproof strips are inlaid on the edges of both the door frame 2 and the door leaf 1. A first groove 7 and a second groove 20 are respectively opened on one side of the door frame 2 and one side of the door leaf 1. One end of the magnetic sound-absorbing strip 6 is snapped into the inside of the first groove 7, and one side of the PU sponge 8 is snapped into the inside of the second groove 20. A TPE skeleton 9 is fixedly inlaid inside the PU sponge 8, and a magnetic strip 10 is fixedly inlaid on one side of the PU sponge 8. The magnetic sound-absorbing strip 6 is in contact with one side of the magnetic strip 10. Specifically, the grid-shaped solid wood keel frame 11 can enhance the... The overall structural strength of door leaf 1 is enhanced to prevent deformation. The rigid-flexible composite core of graphite homogeneous board and Class A fire-resistant functional board has excellent thermal insulation and fire resistance performance, improving the energy efficiency and safety level of the entrance door. The intumescent fireproof strips embedded on the edges of door frame 2 and door leaf 1 can expand and seal gaps when exposed to fire, enhancing fire resistance and sound insulation. The first groove 7 of door frame 2 and the second groove 20 of door leaf 1 provide installation positioning for magnetic sound-absorbing strip 6 and PU sponge 8, respectively, ensuring assembly stability. The TPE skeleton 9 inside PU sponge 8 can enhance its structural support and prevent compression deformation. The magnetic strip 10 and magnetic sound-absorbing strip 6 can tightly fill the gap between door leaf 1 and door frame 2, effectively blocking noise transmission.

[0020] Working principle: When door leaf 1 is closed, the magnetic sound-absorbing strip 6 on one side of door leaf 1 is attracted to the PU sponge 8 on one side of door frame 2, preventing door leaf 1 from directly colliding with door frame 2 and generating noise, while filling the gap between the two. In addition, during the closing process of door leaf 1, the upper sliding plate 17 drives the circular impact rod 19 to slide along the limiting slide seat 18 and impact the impact plate 15 on door frame 2, which enables the lower sliding plate 16 to push the aluminum alloy support plate 4 and overcome the tension of the tension spring 12 to descend. Then, it drives the silicone pad 3 on the bottom surface to extend out of the aluminum alloy frame 5, closely adhering to the ground, sealing the gap at the bottom of the door, and blocking the air transmission of sound. When door leaf 1 is opened, the circular impact rod 19 disengages from the impact plate 15, the tension spring 12 resets and pulls the aluminum alloy support plate 4 upward, while the silicone pad 3 retracts into the aluminum alloy frame 5, without affecting the opening and closing of door leaf 1.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
