Description
Technical Field
[0001] This utility model relates to the field of door leaf technology, and in particular to a door leaf including a thermal break structure. Background Technology
[0002] Aluminum alloy doors and windows are widely used in modern architecture. Ordinary aluminum alloy doors and windows are widely used in buildings due to their advantages such as light weight, easy installation, reusable materials, and environmental friendliness. However, with the development of technology, aluminum alloy profiles have shown poor thermal insulation performance compared to wood, due to their high thermal conductivity. Especially with the emergence of passive buildings, the requirements for building doors and windows have become increasingly stringent, demanding high levels of sound insulation, thermal insulation, and airtightness.
[0003] Traditional thermal break windows and doors use fixed thermal insulation material to fill the thermal break cavity, which has the problem of poor seasonal adaptability: excessive thermal insulation performance in summer leads to insufficient ventilation demand, insufficient heat preservation in winter causes energy waste, and the sealing performance deteriorates due to thermal expansion and contraction of materials during transitional seasons. It is not easy to adjust and has certain room for optimization. Therefore, it is necessary to design door leaves with thermal break structure to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a door leaf with a thermal break structure to solve the problem of inconvenience in adjustment mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a door leaf with a thermal break structure, including a door leaf outer panel and a first fixing member, wherein the door leaf outer panel is provided on the outside of the first fixing member;
[0006] The inner side of the first fixing member is connected to the thermally broken main material. The inner side of the thermally broken main material is connected to the second fixing member via a slot. The inner side of the second fixing member is connected to the inner panel of the door leaf. Metal connectors are fixed to both ends of the inner side of the second fixing member. A rotating shaft is connected to the inner side of the second fixing member between the metal connectors. A third gear and a first gear are fixed to both sides of the rotating shaft, respectively. A reinforcing frame is connected inside the second fixing member. A rotating rod is connected inside the reinforcing frame via an auxiliary rolling sleeve. A second gear is fixed to the outer side of the rotating rod. The second gear meshes with the first gear. The two ends of the inner side of the metal connector are respectively connected to the upper ceramic fiber heat insulation plate and the lower ceramic fiber heat insulation plate. The bottom end of the upper ceramic fiber heat insulation plate and the top end of the lower ceramic fiber heat insulation plate are provided with mounting grooves, and the inside of the mounting grooves is fixed with racks. The racks mesh with the third gear. An insert is connected between the first fixing member and the second fixing member. The inner side of the second fixing member is connected with an inner corner guard. The inner sides of the upper ceramic fiber heat insulation plate and the lower ceramic fiber heat insulation plate are provided with closing grooves.
[0007] Furthermore, guide blocks are fixed on both sides inside the second fixing member, and guide grooves are provided on both sides of the upper ceramic fiber heat insulation plate and the lower ceramic fiber heat insulation plate, and the guide grooves are connected to the guide blocks.
[0008] Furthermore, the width of the guide groove is matched with the width of the guide block, and both the guide groove and the guide block are symmetrically arranged about the central axis of the lower ceramic fiber insulation board.
[0009] Furthermore, a knob is fixed to the inner side of the rotating rod, and a cover plate is provided on the second fixing member outside the knob.
[0010] Furthermore, a second resistance bar is uniformly fixed on the outer side of the rotating rod, and a rotating groove is provided on the side of the second fixing member near the knob, and a first resistance bar is uniformly arranged inside the rotating groove.
[0011] Furthermore, the cross-section of the second resistance bar is semi-circular, and the second resistance bar and the first resistance bar are arranged in a two-way longitudinal and transverse pattern.
[0012] Furthermore, a heat insulation layer is provided on the outer side of the main thermal break material, and the material of the heat insulation layer is one of glass fiber, aluminum silicate insulation cotton, polyurethane foam material, and inorganic board.
[0013] Furthermore, the heat insulation layer can be configured in multiple ways, arranged in a stepped manner.
[0014] Furthermore, the main material of the thermal break is steel, aluminum, steel-wood, or steel-wood-aluminum.
[0015] Compared with the prior art, the beneficial effect of this utility model is that the door leaf with the thermal break structure realizes the function of easy adjustment;
[0016] By turning the knob, the rotating rod is driven to rotate, which drives the second gear to mesh with the first gear, thus driving the rotating shaft to rotate. The rotating shaft drives the third gear to rotate and mesh with the upper and lower racks. The ceramic fiber insulation board is opened and closed by the downward movement of the two sets of racks, thereby changing the material contact state of the heat transfer channel inside the broken bridge through the sliding component.
[0017] In summer mode, the heat conduction path can be blocked to the maximum extent by closing the ceramic fiber insulation boards. In winter mode, some heat conduction can be selectively allowed, that is, moderate heat preservation can be carried out. In the transitional season, the opening and closing distance can achieve an intermediate adjustment state, that is, the temperature difference between the inner and outer layers of the door is reduced under dynamic adjustment, thereby reducing problems such as profile deformation and seal aging caused by thermal expansion and contraction.

[0026] Please see Figures 1-5 The present invention provides the following technical solution:
[0027] Example 1
[0028] To address the inconvenience of adjustment in existing technologies, the following solution is disclosed, specifically as follows: Figure 1 , Figure 2 and Figure 3 As shown, the door leaf with a thermal break structure provided in this application includes an outer door leaf panel 1 and a first fixing member 2. The outer door leaf panel 1 is disposed on the outer side of the first fixing member 2, and the thermal break main material 3 is connected to the inner side of the first fixing member 2. The inner side of the thermal break main material 3 is connected to a second fixing member 6 through a slot 7, and the inner side of the second fixing member 6 is connected to an inner door leaf panel 11. Metal connectors 9 are fixed at both ends of the inner side of the second fixing member 6, and a pivot 17 is connected to the inner side of the second fixing member 6 between the metal connectors 9. A third gear 25 and a first gear 18 are fixed to both sides of the second fixing member 6. A reinforcing frame 16 is connected inside the second fixing member 6, and a rotating rod 14 is connected inside the reinforcing frame 16 through an auxiliary rolling sleeve 15. A second gear 19 is fixed to the outside of the rotating rod 14, and the second gear 19 and the first gear 18 are meshed together. The two ends of the inner side of the metal connector 9 are respectively connected to an upper ceramic fiber heat insulation plate 20 and a lower ceramic fiber heat insulation plate 21. The bottom end of the upper ceramic fiber heat insulation plate 20 and the top end of the lower ceramic fiber heat insulation plate 21 are both... An installation groove 23 is provided, and a rack 22 is fixed inside each of the installation grooves 23. The rack 22 meshes with the third gear 25. An insert 5 connects the first fixing member 2 and the second fixing member 6. An inner corner guard 12 is connected to the inner side of the second fixing member 6. A closed groove 24 is provided on the inner side of both the upper ceramic fiber heat insulation board 20 and the lower ceramic fiber heat insulation board 21. Guide blocks 8 are fixed on both sides inside the second fixing member 6. Guide grooves are provided on both sides of both the upper ceramic fiber heat insulation board 20 and the lower ceramic fiber heat insulation board 21. 10, and the guide grooves 10 are all connected to the guide blocks 8. The width of the guide grooves 10 is matched with the width of the guide blocks 8. The guide grooves 10 and the guide blocks 8 are symmetrically arranged about the central axis of the lower ceramic fiber insulation board 21. The outer side of the thermal break main material 3 is provided with a thermal insulation layer 4. The material of the thermal insulation layer 4 is one of glass fiber, aluminum silicate insulation cotton, polyurethane foam material, and inorganic board. Multiple thermal insulation layers 4 can be set and arranged in a stepped shape. The thermal break main material 3 is steel, aluminum, steel-wood and / or steel-wood-aluminum.
[0029] In this embodiment, during use, the knob 26 is turned to rotate the lever 14, which in turn drives the second gear 19 and the first gear 18 to mesh and connect, thereby driving the rotating shaft 17 to rotate. The rotating shaft 17 drives the third gear 25 to rotate and mesh with the upper and lower racks 22. The ceramic fiber insulation board is opened and closed by the downward movement of the two sets of racks 22. This changes the material contact state of the heat transfer channel inside the thermal break through the sliding component. In summer mode, the heat conduction path is blocked to the maximum extent by closing the ceramic fiber insulation board. In winter mode, partial heat conduction can be selectively allowed, i.e., moderate heat preservation. In transitional seasons, the opening and closing distance can achieve an intermediate adjustment state, i.e., the temperature difference between the inner and outer layers of the door is reduced under dynamic adjustment, thereby reducing problems such as profile deformation and seal aging caused by thermal expansion and contraction.
[0030] Example 2
[0031] This embodiment differs from Embodiment 1 in that it employs a self-locking structure to improve operational convenience, specifically as follows: Figure 4 and Figure 5 As shown, a knob 26 is fixed on the inner side of the rotating rod 14, and a cover plate 13 is provided on the second fixing member 6 on the outer side of the knob 26. A second resistance bar 29 is evenly fixed on the outer side of the rotating rod 14. A rotating groove 28 is provided on the side of the second fixing member 6 near the knob 26, and a first resistance bar 27 is evenly arranged inside the rotating groove 28. The cross-section of the second resistance bar 29 is semi-circular, and the second resistance bar 29 and the first resistance bar 27 are arranged in a longitudinal and transverse bidirectional design.
[0032] In this embodiment, during use, a second resistance bar 29 and a first resistance bar 27 are provided on the outside of the rotating rod 14. During rotation, the user needs to use the second resistance bar 29 and the first resistance bar 27, which are made of hard elastic material, to rotate by friction. Under the action of resistance, the rotating rod 14 is not easy to rotate on its own after rotation. That is, after rotation, it can achieve self-locking through friction. Furthermore, the area where the knob 26 is located can be covered by the cover plate 13 to maintain the integrity and aesthetics.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
