[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1

[0037] Please see Figures 1 to 8 This utility model is a snap-fit ​​type thermally broken aluminum insulated entrance door, including a door frame, a door leaf 400, and a side window 700; the door frame includes an upper horizontal door frame 100, a right vertical door frame 200, a left vertical door frame 300, and a lower horizontal door frame 600 that are connected end to end to form a rectangular frame. A middle vertical frame 500 is fixedly connected between the upper horizontal door frame 100 and the lower horizontal door frame 600, and the side window 700 is installed between the middle vertical frame 500 and the left vertical door frame 300. The door leaf 400 is connected to the right vertical door frame 200 by a hinge. The middle vertical frame 500 can divide the door frame into a side window installation area and a door leaf installation area, so that indoor lighting can be achieved through the side window 700 and passage needs can be met through the door leaf 400.

[0038] The upper horizontal door frame 100 includes an upper inner thermally broken aluminum 102. An upper inner decorative panel 101 and an upper outer decorative panel 105 are fixedly connected to the inner and outer sides of the upper inner thermally broken aluminum 102, respectively. The upper inner thermally broken aluminum 102 has good thermal insulation performance, which can effectively block the transfer of heat between indoors and outdoors and reduce indoor energy consumption. The upper inner decorative panel 101 and the upper outer decorative panel 105 respectively wrap the inner and outer sides of the upper inner thermally broken aluminum 102, which can protect the upper inner thermally broken aluminum 102 from external environmental corrosion and extend its service life.

[0039] The right vertical door frame 200 includes a right inner thermally broken aluminum 202. The inner and outer sides of the right inner thermally broken aluminum 202 are respectively fixedly connected to a right inner decorative panel 201 and a right outer decorative panel 205. The right inner thermally broken aluminum 202 not only provides stable structural support to ensure that the door leaf 400 is not easy to loosen after installation, but its thermally broken aluminum material can also enhance the thermal insulation effect of the right vertical door frame 200 and reduce heat loss from the side of the door frame. The right inner decorative panel 201 and the right outer decorative panel 205 can protect the right inner thermally broken aluminum 202.

[0040] The left vertical door frame 300 includes a left inner thermally broken aluminum 302. The left inner thermally broken aluminum 302 is fixedly connected to the left inner decorative panel 301 and the left outer decorative panel 307 on its inner and outer sides, respectively. The left inner thermally broken aluminum 302 and the right inner thermally broken aluminum 202 are structurally symmetrical, which can balance the overall force of the door frame and ensure that the left vertical door frame 300 supports the ear window 700 stably, preventing the ear window 700 from tilting after long-term use. The left inner decorative panel 301 and the left outer decorative panel 307 can isolate external impurities from direct contact with the left inner thermally broken aluminum 302, reducing the wear and corrosion of the thermally broken aluminum.

[0041] The lower horizontal door frame 600 includes a lower inner thermally broken aluminum 601, and a lower outer decorative panel 602 is fixedly connected to the outer side of the lower inner thermally broken aluminum 601. The lower inner thermally broken aluminum 601 can bear part of the weight of the door leaf 400 and the ear window 700, ensuring that the lower horizontal door frame 600 is not prone to sinking or deformation after long-term use. At the same time, its thermal insulation performance can block the upward transmission of cold air from the ground and improve the temperature stability of the bottom area of ​​the room. The lower outer decorative panel 602 can protect the lower inner thermally broken aluminum 601 from ground water stains and dust corrosion, and extend the service life of the lower horizontal door frame 600.

[0042] The central vertical frame 500 includes an inner thermally broken aluminum alloy 502. The inner and outer sides of the inner thermally broken aluminum alloy 502 are respectively fixedly connected to an inner decorative panel 501 and an outer decorative panel 508. The inner thermally broken aluminum alloy 502 provides strong structural support for the central vertical frame 500, ensuring that it can stably separate the area of ​​the window 700 and the door leaf 400, and preventing the central vertical frame 500 from shifting due to vibration from opening and closing the door leaf. The thermal insulation performance of the inner thermally broken aluminum alloy 502 can reduce heat exchange between the window 700 and the door leaf 400, further improving the overall thermal insulation effect of the entrance door. The inner decorative panel 501 and the outer decorative panel 508 can protect the inner thermally broken aluminum alloy 502.

[0043] Specifically, the cross-sections of the upper outer decorative panel 105, the right outer decorative panel 205, and the left outer decorative panel 307 are all convex, the cross-section of the lower outer decorative panel 602 is L-shaped, and the cross-section of the middle outer decorative panel 508 is cross-shaped. The convex cross-sections of the upper outer decorative panel 105, the right outer decorative panel 205, and the left outer decorative panel 307 can form a raised support structure, providing a stable base for subsequent installation of the door frame stop sealing strip 900, ensuring that the sealing strip is not easy to fall off after installation. The L-shaped cross-section of the lower outer decorative panel 602 is adapted to the installation position of the lower horizontal door frame 600, which can better fit the ground or the bottom structure of the door frame, improving the installation sealing of the lower horizontal door frame 600. The cross-shaped cross-section of the middle outer decorative panel 508 can enhance the central support force, and at the same time, it is easy to distinguish the installation areas of the ear window 700 and the door leaf 400, improving the structural stability and functional zoning clarity of the middle vertical frame 500.

[0044] Furthermore, the protruding parts of the upper outer decorative panel 105, the protruding parts of the right outer decorative panel 205, the lower outer decorative panel 602, and the middle outer decorative panel 508 facing the door leaf 400 are all snapped together with door frame stop sealing strips 900 that fit snugly against the outer side of the door leaf 400. The door frame stop sealing strips 900 fit tightly against the outer side of the door leaf 400, which can effectively fill the gap between the door leaf 400 and the door frame, preventing external dust, rainwater, and cold air from entering the room. At the same time, it can reduce the collision noise when the door leaf 400 is closed, improving the living comfort. The door frame stop sealing strips 900 are installed by snapping together, which facilitates the replacement and maintenance of the sealing strips in the future and reduces the cost of use.

[0045] Glass strip bases 1200 are fixedly connected to the exterior of the inner thermally broken aluminum 502, the left inner thermally broken aluminum 302, the upper inner thermally broken aluminum 102, and the lower inner thermally broken aluminum 601. Glass strip bases 1200, the left outer decorative panel 307, the middle outer decorative panel 508, the upper outer decorative panel 105, and the lower outer decorative panel 602 facing the side window 700 are all snapped with glass sealing strips 800 that fit snugly against the side window 700. The glass strip base 1200 provides a stable mounting carrier for the glass sealing strip 800. The glass sealing strip 800 fits tightly against the side window 700, which can effectively prevent moisture and dust from entering the gap between the side window 700 and the door frame, protect the side window glass, and at the same time enhance the thermal insulation and sound insulation effect of the side window area, reducing the external noise entering the room.

[0046] The upper inner thermally broken aluminum 102, lower inner thermally broken aluminum 601, right inner thermally broken aluminum 202, and middle inner thermally broken aluminum 502 are all fixedly connected to the door leaf 400 with a door frame middle sealing strip 1300. The door frame middle sealing strip 1300 and the door frame stop sealing strip 900 form a double sealing structure, further filling the gap between the door leaf 400 and the door frame, greatly improving the sealing performance of the door leaf area, more effectively isolating external temperature changes and noise, improving indoor temperature stability and quietness. The sealing strip is fixedly connected to the thermally broken aluminum, is firmly installed, and is not easy to fall off due to frequent door opening and closing, ensuring long-term stable sealing effect.

[0047] The bottom inner thermally broken aluminum 601 is fixedly connected to the top of the glass bottom edge pad 609 that fits against the bottom of the ear window 700. The glass bottom edge pad 609 can form a flexible support for the bottom of the ear window 700, avoiding direct hard contact between the ear window glass and the bottom inner thermally broken aluminum 601, reducing the risk of glass wear and breakage caused by vibration or pressure, and extending the service life of the ear window 700. At the same time, the glass bottom edge pad 609 can fill the small gap between the bottom of the ear window 700 and the lower horizontal door frame 600, further enhancing the sealing and heat preservation effect of the ear window area and preventing cold air from seeping in from the bottom gap.

[0048] The interior of the upper outer decorative panel 105, the lower outer decorative panel 602, the right outer decorative panel 205, the middle outer decorative panel 508, and the left outer decorative panel 307 are all filled with matching solid wood strips. The solid wood strips have good thermal insulation properties and can form a double insulation structure with the thermally broken aluminum, further reducing the efficiency of heat transfer between indoors and outdoors, improving the overall insulation effect of the entrance door, and reducing energy consumption for heating in winter and cooling in summer.

[0049] The interior of door leaf 400 is a solid wood frame structure with wooden joists, and the gaps between the wooden joists are filled with thermal insulation material, which can enhance the structure of door leaf 400 while improving its thermal insulation and sound insulation functions.

[0050] The operation process of this embodiment is as follows: When the temperature difference between indoors and outdoors is too large, firstly, the upper inner thermally broken aluminum 102, right inner thermally broken aluminum 202, left inner thermally broken aluminum 302, lower inner thermally broken aluminum 601, and middle inner thermally broken aluminum 502, with their excellent thermal insulation performance, actively block the direct transfer of heat between indoors and outdoors. In winter, this prevents warm indoor air from escaping quickly through the main structure of the door frame, and in summer, it prevents cold winter air or hot summer air from being conducted into the room through the thermally broken aluminum. Next, the upper outer decorative panel 105, lower outer decorative panel 602, right outer decorative panel 205, middle outer decorative panel 508, and left outer decorative panel 302 are filled with thermally broken aluminum. The solid wood strips inside 07 form a double insulation structure with each thermally broken aluminum component, further reducing the heat penetration efficiency through the outer decorative panel and slowing down the rate of indoor and outdoor temperature exchange. At this time, the door frame stop sealing strip 900, which is snapped onto the protrusions of the upper outer decorative panel 105, the right outer decorative panel 205, the lower outer decorative panel 602, and the middle outer decorative panel 508 facing the door leaf 400, fits tightly against the outside of the door leaf 400. Simultaneously, it cooperates with the sealing strip 1300 fixed in the middle of the door frame facing the door leaf 402, the upper inner thermally broken aluminum 102, the lower inner thermally broken aluminum 601, the right inner thermally broken aluminum 202, and the middle inner thermally broken aluminum 502, forming a double insulation structure. The sealing barrier effectively blocks cold winter air or hot summer air from seeping into the room through the gap between the door leaf 400 and the door frame, while also preventing indoor air of varying temperatures from escaping through the gap. For the ear window 700 area, the glass strip base 1200, fixed to the outside of the innermost thermally broken aluminum 502, left innermost thermally broken aluminum 302, upper innermost thermally broken aluminum 102, and lower innermost thermally broken aluminum 601, provides stable support for the snap-fit ​​glass sealing strip 800, ensuring a tight fit between the glass sealing strip 800 and the ear window 700. This prevents heat leakage or cold air infiltration at the gap between the ear window 700 and the door frame under extreme temperature differences. Simultaneously, the glass strip fixed to the top of the lower innermost thermally broken aluminum 601... The bottom edge pad 609 provides flexible protection for the bottom of the ear window 700 and fills the tiny gap between the bottom of the ear window 700 and the lower horizontal door frame 600, further enhancing the sealing and heat preservation effect of the ear window area. Through the synergistic effect of the upper inner thermally broken aluminum 102, right inner thermally broken aluminum 202, left inner thermally broken aluminum 302, lower inner thermally broken aluminum 601, middle inner thermally broken aluminum 502, solid wood strips inside each outer decorative panel, door frame stop sealing strip 900, door frame middle sealing strip 1300, glass sealing strip 800, and glass bottom edge pad 609, the indoor temperature can be effectively maintained and the increase in heating or cooling energy consumption caused by excessive indoor and outdoor temperature differences can be reduced.

[0051] Example 2

[0052] Please see Figure 2 as well as Figures 4 to 8Based on the first specific embodiment, outer buckle strips 1100 are fixedly connected to the diagonal corners of the protrusions of the upper outer decorative panel 105, the right outer decorative panel 205 and the left outer decorative panel 307 on the side away from the door leaf 400, as well as the two diagonal corners below the middle outer decorative panel 508. The outer buckle strips 1100 are fixed at the diagonal corners of the decorative panels, which can reinforce the corners of the decorative panels and prevent the protrusions of the decorative panels or the middle outer decorative panels 508 from warping or falling off due to external impact or long-term use, thereby improving the structural stability of the decorative panels.

[0053] The glass strip base 1200 is a right-angled trapezoid, and the glass strip base 1200 is snapped with a glass strip buckle 1201 on its inclined surface. The glass strip buckle 1201 can further fix the window 700 and prevent the glass from shifting due to vibration. At the same time, the snap-fit ​​method makes it easy to install and remove the glass strip buckle 1201. If the window 700 needs to be replaced or the sealing strip needs to be maintained in the future, the operation will be more convenient.
