[0064] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0065] As shown in Figure 1 , it comprises a door leaf 1 and a door frame 2, wherein the door frame 2 is fixedly installed in a wall surface, and the door leaf 1 is hinged to the door frame 2 so as to switch the door leaf 1 between an open state and a closed state.

[0066] It is worth mentioning here that, as Figure 1As shown in the drawings, the door frame 2 adopts a C-shaped structure with the opening downward, such as Figure 2 As shown in the drawings, the door frame 2 can also adopt a "mouth" shape, and the door frame 2 includes a top baffle 22 and a bottom sill 23.

[0067] In this embodiment, as shown in the drawings, Figure 2 and Figure 3 The door leaf 1 and the door frame 2 are hinged by a top-bottom shaft 1000 to realize the rotation of the door leaf 1 relative to the door frame 2, so as to switch the off-axis door between the open state and the closed state.

[0068] Specifically, the top-bottom shaft 1000 includes a top sheet 1001, a bottom sheet 1002, a top shaft 1003 and a bottom shaft 1004, wherein the top sheet 1001 is fixedly installed on the baffle 22 of the door frame 2 by bolts, the bottom sheet 1002 is fixedly installed on the sill 23 of the door frame 2 by bolts, or the bottom sheet 1002 is fixedly installed on the ground by the pre-buried manner, the top shaft 1003 is installed on the top of the door leaf 1, and the bottom shaft 1004 is installed on the bottom of the door leaf 1. The top shaft 1003 is rotationally connected with the top sheet 1001, and the bottom shaft 1004 is rotationally connected with the bottom sheet 1002, so as to realize the installation of the door leaf 1.

[0069] It is worth mentioning that the axes of the top shaft 1003 and the bottom shaft 1004 coincide with each other, and the central axis of the top shaft 1003 is staggered with the central axis of the door leaf 1.

[0070] The advantages of the top shaft 1003 and the bottom shaft 1004 deviating from the center of the door leaf 1 are that a larger opening angle and more flexible space utilization can be realized.

[0071] As shown in the drawings, Figure 4 The door leaf 1 can be switched between the open state and the closed state by rotating around the top-bottom shaft 1000, and specifically, Figure 4 The dashed part in the drawings indicates the open state of the door leaf 1, Figure 4 The solid part in the drawings indicates the closed state of the door leaf 1.

[0072] As mentioned in the background art, the prior art adopts a steel structure or a pure aluminum profile, wherein due to the good heat conduction performance of the profile, the heat insulation performance of the traditional off-axis door is poor, which is difficult to meet the requirements of the "General Code for Building Energy Conservation and Renewable Energy Utilization", and therefore it is necessary to improve the heat insulation performance of the off-axis door.

[0073] As shown in the drawings, Figure 5 The door leaf 1 includes a door leaf body 12 and a door leaf frame 13, and the door leaf frame 13 is built in a frame structure to improve the strength of the door leaf 1 structure and reduce the risk of deformation of the door leaf 1.

[0074] The application makes structural improvements to the traditional steel structure and the use of pure aluminum profiles, wherein the door leaf frame 13 and the door frame 2 are assembled by the aluminum alloy frame 10, and it is worth noting that the door leaf frame 13 is in a "mouth" structure connected head to tail.

[0075] The aluminum alloy frame 10 includes two vertical segments and two horizontal segments, the vertical segments are arranged along the length direction of the door leaf frame 13 or the door frame 2, and the horizontal segments are arranged along the width direction of the door leaf frame 13 or the door frame 2, and specifically, as shown in the figure, the vertical segments and the horizontal segments of the aluminum alloy frame 10 are fixedly connected through the corner code 8; the corner code 8 includes two fixed edges with a right angle, the fixed edges are attached to the side wall of the inner cavity of the aluminum alloy frame 10, and then fixed through bolts. Figure 6

[0076] In order to improve the heat insulation performance of the aluminum alloy frame 10, in the embodiment, as shown in the figure, the aluminum alloy frame 10 includes a first frame 101 and a second frame 102, wherein the first frame 101 and the second frame 102 are arranged along the normal direction of the door leaf 1, the first frame 101 and the second frame 102 are connected through a plurality of heat insulation strips 9, and specifically, the heat insulation strips 9 are connected with the first frame 101 and the second frame 102 in a plug-in manner, the first frame 101 and the second frame 102 are made of aluminum alloy material, and the heat insulation strips 9 are made of polyurethane composite material, the arrangement of the heat insulation strips 9 separates the first frame 101 and the second frame 102, avoids the contact between the first frame 101 and the second frame 102, and thus reduces the heat conduction between the inside and outside of the door leaf 1 through the aluminum alloy frame 10, thereby improving the heat insulation performance of the door leaf 1 and the door frame 2. Figure 7 Specifically, a heat insulation space 100 is also formed between the adjacent two heat insulation strips 9, and the heat insulation space 100 can be left empty here to reduce the weight of the door leaf 1, thereby reducing the stress problem of the heaven and earth shaft 1000 and the risk of sagging of the door leaf 1; or the heat insulation space 100 is filled with heat insulation material to further improve the heat insulation performance of the door leaf 1 and the door frame 2.

[0077] As shown in the figure,

[0078] and Figure 5 and Figure 8 ​As shown, the door leaf body 12 includes an aluminum plate 121, a blocking baffle 122, a sealing plate 123, and a honeycomb aluminum 124. The blocking baffle 122 has a C-shaped cross section, is arranged on the inner side of the door leaf frame 13, and is in contact with the vertical section of the door leaf frame 13. The blocking baffle 122 is arranged in two groups along the width direction of the door leaf 1. The honeycomb aluminum 124 is arranged between the two adjacent blocking baffles 122 to strengthen the strength of the door leaf 1. The sealing plate 123 is arranged on both sides of the blocking baffle 122 to encapsulate the honeycomb aluminum 124. The aluminum plate 121 is attached to the outer side of the door leaf frame 13 to decorate the door leaf 1.

[0079] When the door leaf 1 is installed on the door frame 2 through the top-and-bottom shaft 1000, there is a gap between the door leaf 1 and the door frame 2, which also affects the heat preservation performance of the off-axis door.

[0080] To solve this problem, the utility model patent with the authorization announcement number CN222478492U disclosed in the background art discloses a technical solution. The first sealing component is inflated or deflated by the inflation and deflation component, so as to switch between the inflated state and the deflated state of the first sealing component, thereby realizing the sealing of the door leaf 1 after being closed. In the deflated state, the door leaf 1 is convenient to rotate relative to the door frame 2, thereby opening the off-axis door.

[0081] This technical solution inflates or deflates the first sealing component through the inflation and deflation component, thereby solving the problem of filling the gap between the door leaf 1 and the door frame 2. After the door leaf is closed, the inflation and deflation component needs to be inflated manually, so that the first sealing component remains in the inflated state, thereby expanding the first sealing component to compensate for the gap space. When the door leaf needs to be opened, the inflation and deflation component needs to be deflated manually, so that the first sealing component is in the deflated state, thereby opening the door leaf 1.

[0082] However, in the conventional use process of the off-axis door, after the door is opened by people, they can directly pass through the door frame. After people leave, the door is manually pushed to rotate, thereby switching the door leaf 1 to the closed state. At this time, people will directly leave, but the scheme disclosed in the above document needs to be inflated by the inflation and deflation component, and then people can leave, which is different from the habit of people's activities and will cause discomfort when closing the door.

[0083] Therefore, in the present application, the scheme for blocking the gap between the door leaf 1 and the door frame 2 is improved to adapt to the habit of people closing the door.

[0084] As shown in FIG. 1, the door leaf 1 is installed on the door frame 2 through the top-and-bottom shaft 1000. The door leaf 1 is connected to the door frame 2 through the top-and-bottom shaft 1000, and the door leaf 1 is rotatable relative to the door frame 2. The door leaf 1 is provided with a door leaf frame 13, and the door leaf frame 13 is provided with a first sealing component 14. The first sealing component 14 is arranged on the inner side of the door leaf frame 13, and the first sealing component 14 is in contact with the door frame 2. The first sealing component 14 is arranged in two groups along the width direction of the door leaf 1. The first sealing component 14 is arranged in the inflated state or the deflated state. Figure 9As shown, it includes a first sealing part 3 and a drive part 4 that drives the first sealing part 3 to switch between a retracted state and an extended state. The first sealing part 3 can be installed on either the door leaf 1 or the door frame 2. When the drive part 4 pushes the first sealing part 3 outward into the extended state, the extended first sealing part 3 can seal the gap between the door leaf 1 and the door frame 2, thereby achieving a seal between the door leaf 1 and the door frame 2, improving the heat insulation performance of the off-axis door, and reducing the impact of the gap on the heat insulation performance of the off-axis door.

[0085] In this embodiment, the first sealing part 3 is provided on the door leaf 1. When the first sealing part 3 is in the retracted state, the first sealing part 3 is completely sunk into the interior of the door leaf 1. When the first sealing part 3 is in the extended state, the first sealing part 3 extends into the door frame 2, thereby achieving the sealing of the gap between the door leaf 1 and the door frame 2.

[0086] It is also worth noting that the first sealing part 3 can be provided in four sets. The four sets of first sealing parts 3 are connected end to end and set on the side of the door leaf 1. When the four sets of first sealing parts 3 extend at the same time, they can completely seal the gap between the door leaf 1 and the door frame 2.

[0087] Furthermore, the first sealing part 3 can be provided in two sets, with the two sets of first sealing parts 3 arranged along the height direction of the door leaf 1, respectively located at the top and bottom of the door leaf 1. The first sealing parts 3 are used to seal the gaps between the door leaf 1 and the top and bottom of the door frame 2. It also includes two sets of second sealing parts 7, such as... Figure 8 As shown, two sets of second sealing parts 7 are arranged along the width direction of the door leaf 1 to seal the gap between the door leaf 1 and the side of the door frame 2.

[0088] In order to control the state of the first sealing part 3, such as Figure 9 As shown, it also includes a locking component 5 and an unlocking part 6, wherein, as Figure 10 As shown, the unlocking part 6 includes an unlocking transmission member 61 and an unlocking drive member 62. The locking component 5 is disposed on the side of the first sealing part 3. The unlocking transmission member 61 is connected to the locking component 5. One of the unlocking transmission member 61 and the unlocking drive member 62 is installed on the door leaf 1, and the other is installed on the door frame 2. When the first sealing part 3 is retracted into the door leaf 1, the locking component 5 is used to restrict the movement of the first sealing part 3, thereby restricting the first sealing part 3 from switching to the extended state. When the door leaf 1 needs to be opened, the unlocking drive member 62 drives the unlocking transmission member 61 to move, and then the unlocking transmission member 61 drives the locking component 5 to move, thereby releasing the locking component 5 from locking the first sealing part 3. At this time, the drive part 4 pushes the first sealing part 3 out of the door leaf 1, so that the door leaf 1 switches from the retracted state to the extended state. At this time, the first sealing part 3 is inserted into the door frame 2, thereby achieving the sealing of the gap between the door leaf 1 and the door frame 2.

[0089] In order to realize the installation of the first sealing part 3, in the embodiment, as shown in Figure 11 the horizontal sections of the top and bottom of the door leaf frame 13 are also made of aluminum alloy frames 10, specifically, the horizontal sections here include first frames 101 and second frames 102 arranged along the normal direction of the door leaf 1, and the first frames 101 and the second frames 102 of the top and bottom horizontal sections are connected by the heat insulation strips 9, wherein the aluminum alloy frames 10 at the top splice an installation groove 11 with an upward opening, and the aluminum alloy frames 10 at the bottom splice an installation groove 11 with a downward opening, wherein the first sealing part 3 is slidingly installed in the installation groove 11, and the first sealing part 3 can slide along the height direction of the door leaf 1.

[0090] Specifically, as shown in Figure 12 the first sealing part 3 includes a sealing piece 31 and a sliding piece 32, wherein the first sealing part 3 is in a strip shape and extends along the width direction of the door leaf 1, the sealing piece 31 and the sliding piece 32 are integrally formed, the cross section of the first sealing part 3 is in a "T" shape, the side wall of the sliding piece 32 abuts against the side wall of the installation groove 11, and a gap is left between the side wall of the sealing piece 31 and the side wall of the installation groove 11 to allow the sliding piece 32 to be clamped by the locking assembly 5, so that the first sealing part 3 is maintained in the retracted state.

[0102] Specifically, as shown in the figure, Figure 17 The transmission mechanism 615 comprises a first rod 6151, a second rod 6152 and a third rod 6153, the first rod 6151 is vertically arranged in the heat insulation space 100 and slides along the longitudinal direction, and the first rod 6151 is slidingly connected with the sliding block 612; the second rod 6152 is horizontally arranged and connected with one end of the first rod 6151 away from the sliding block 612, and the third rod 6153 is provided with two groups, one end of the third rod 6153 is rotationally connected with the second rod 6152, and the other end of the third rod 6153 is rotationally connected with the turnover rod 513.

[0103] Specifically, as shown in the figure, Figure 19 The sliding block 612 is provided with two groups of inclined grooves 6121, and the two groups of inclined grooves 6121 form a horizontally arranged "eight" shape, wherein the side with a larger opening faces the spring 613, and the side with a smaller opening faces the horizontal shaft 1000, and the end of the first rod 6151 is inserted into the inclined groove 6121 to form a sliding connection.

[0104] Through the above arrangement, after the sliding block 612 is attracted by the unlocking driving member 62, the sliding block 612 moves towards the unlocking driving member 62 and compresses the spring 613, at this time, the first rod 6151 is pulled towards the middle position of the sliding block 612 of the door leaf 1 through the inclined groove 6121, and the middle position is relative to the up-down direction, thereby driving the locking buckle 51 to turn through the second rod 6152, the third rod 6153 and the turnover rod 513, so as to realize the switching of the state of the locking assembly 5.

[0105] Specifically, as shown in the figure, Figure 20As shown, the stabilizing block 46 has a vertically arranged through hole 461. The first rod 6151 passes through the through hole 461, and the peripheral wall of the first rod 6151 is slidably connected to the inner wall of the through hole 461. By utilizing the sliding cooperation between the through hole 461 and the first rod 6151, the stability of the movement of the first rod 6151 can be improved, and the problem of mis-locking of the locking buckle 51 can be reduced.

[0106] It is worth noting that the unlocking actuator 62 includes a second magnet 621, such as Figure 10 and Figure 18 As shown, the second magnet 621 is fixedly installed inside the door frame 2, and the second magnet 621 and the first magnet 614 are at the same height.

[0107] The locking buckle 51 is provided in two sets and is located on both sides of the first sealing part 3 respectively, in order to improve the stability of locking the first sealing part 3.

[0108] The third rod 6153 is provided with two sets and is respectively connected to the locking buckles 51 on both sides of the first sealing part 3, so as to realize the synchronous operation of the locking buckles 51 on both sides of the first sealing part 3.

[0109] When door leaf 1 is opened, door leaf 1 is misaligned with door frame 2. At this time, the second magnet 621 releases its attraction to the first magnet 614, and spring 613...

By rotating the handle 43, the traction rope 42 retracts the first sealing part 3 into the mounting groove 11. During this process, the side wall of the sliding member 32 first abuts against the guide slope 5111 of the locking head 511. As the first sealing part 3 moves down, the locking head 511 rotates around the rotating shaft 52, moving the sliding member 32 to below the locking head 511. Finally, the locking head 511 resets, and the locking head 511 engages with the top wall of the sliding member 32, switching the first sealing part 3 to the retracted state.
