Description

Technical Field

[0001] The present application relates to the field of doors, and in particular to an off-axis door. Background Art

[0002] my country's "General Specification for Energy Conservation and Renewable Energy Utilization in Buildings" GB55015-2021 requires that the heat transfer coefficient K value of doors and windows in extremely cold areas is ≤1.8W / (m²・K). Eccentric doors are mostly made of steel structures or pure aluminum profiles. Among them, the energy consumption problem caused by the high thermal conductivity of metal materials is particularly prominent. Due to the particularity of the structure, the energy-saving performance of eccentric doors has become a difficulty in the design industry.

[0003] The off-axis door in the prior art includes a door leaf and a door frame structure, wherein the door leaf is hinged to the door frame through a zenithal axis and a terrestrial axis, and the gap between the door frame and the door leaf often lacks an effective sealing structure, resulting in poor sealing performance of the off-axis door. The existing utility model patent with authorization announcement number CN222478492U discloses a technical solution, wherein a first sealing component is provided on one of the door leaf and the door frame, and also includes an inflation and deflation component matching the first sealing component, wherein the first sealing component can be switched between a bulging state and a deflated state by inflating or deflation of the inflation and deflation component, thereby achieving the closure of the gap between the door frame and the door leaf and improving the sealing performance of the off-axis door.

[0004] Among them, the first sealing component switches its state by inflating and deflating air. The inflating and deflating component needs to be placed inside the door frame or door leaf. When opening or closing the door, the state of the inflating and deflating component needs to be manually controlled to achieve the opening or closing of the off-axis door. Although this technical solution solves the problem of sealing the gap between the door leaf and the door frame, the structure is relatively complicated and the operation is inconvenient.

[0005] Therefore, how to design an off-axis door with improved sealing performance and easy operation has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0012] In an implementable embodiment, the unlocking transmission part includes a positioning frame, a sliding block, a spring, a first magnet and a transmission mechanism. The positioning frame is fixedly installed on the door leaf. The sliding block is arranged in the inner cavity of the positioning frame and slides along the width direction of the door leaf. The first magnet is fixedly installed on the sliding block. The sliding block is power-connected to the flipping part through the transmission mechanism. When the sliding block slides towards the unlocking driving part, the locking buckle is driven to flip around the rotating shaft through the transmission mechanism and the flipping part so that the locking head releases the restriction on the first sealing part.

At this time, the unlocking driving member releases the control of the unlocking transmission member, so that the unlocking transmission member and the locking assembly are reset, and the first sealing portion is restricted in the retracted state again by using the locking assembly, and the door leaf can be opened; The present application provides a new way to seal the gap between the door leaf and the door frame compared with the prior art, replacing the combination solution of the inflation and deflation component and the first sealing part. The door leaf can be opened manually. When the door leaf is closed, the first sealing part can be automatically extended to seal the gap between the door leaf and the door frame. Compared with using the inflation and deflation component to seal the gap, after closing the door leaf, there is no need to worry about the sealing condition of the gap and one can directly leave. The sealing of the gap between the door leaf and the door frame is more convenient.

[0022] To make the objectives, features, and advantages of this application more obvious and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0023] As Figure 1 shown, it includes a door leaf 1 and a door frame 2. Among them, the door frame 2 is fixedly installed in the wall, and the door leaf 1 is hinged to the door frame 2 so that the door leaf 1 can be switched between an open state and a closed state.

[0024] It is worth noting here that, as Figure 1 shown, the door frame 2 adopts a C-shaped structure with an opening downward. As Figure 2 shown, the door frame 2 can also adopt a "mouth" shape. The door frame 2 includes a top stop edge 22 and a bottom sill 23.

[0025] In this embodiment, as Figure 2 and Figure 3 shown, the door leaf 1 and the door frame 2 are hinged by a floor hinge 1000 to realize the rotation of the door leaf 1 relative to the door frame 2, so as to switch the offset hinge door between an open state and a closed state.

[0026] Specifically, the floor hinge 1000 includes a top plate 1001, a bottom plate 1002, a top shaft 1003 and a bottom shaft 1004. Among them, the top plate 1001 is fixedly installed on the edge 22 of the door frame 2 by bolts, and the bottom plate 1002 is fixedly installed on the threshold 23 of the door frame 2 by bolts, or the bottom plate 1002 is fixedly installed on the ground by embedding. The top shaft 1003 is installed at the top of the door leaf 1, and the bottom shaft 1004 is installed at the bottom of the door leaf 1. The top shaft 1003 is rotatably connected to the top plate 1001, and the bottom shaft 1004 is rotatably connected to the bottom plate 1002, so as to realize the installation of the door leaf 1.

[0027] It should be noted 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 misaligned with the central axis of the door leaf 1.

[0028] The advantage of the deviation of the top shaft 1003, the bottom shaft 1004 from the center of the door leaf 1 is that a larger opening angle and more flexible space utilization can be achieved.

[0029] As Figure 4 shown, the door leaf 1 can be switched between the open state and the closed state by rotating around the floor hinge 1000. Specifically, Figure 4 the dotted line part in Figure 4 refers to the open state of the door leaf 1, and

[0030] As mentioned in the background art of this application, the prior art is made of steel structure or pure aluminum profiles. Among them, due to the good heat conduction performance of the profiles, the heat insulation performance of the traditional offset door is poor, and it is difficult to meet the requirements of the "General Code for Building Energy Efficiency and Renewable Energy Utilization". Therefore, it is necessary to improve the heat insulation performance of the offset door.

[0031] As Figure 5 shown, the door leaf 1 includes a door leaf main body 12 and a door leaf frame 13. The door leaf frame 13 is built by a frame structure to improve the strength of the structure of the door leaf 1 and reduce the risk of deformation of the door leaf 1.

[0032] This application makes a structural improvement to the use of traditional steel structures and pure aluminum profiles. Among them, the door leaf frame 13 and the door frame 2 are assembled by aluminum alloy frames 10. It should be noted that the door leaf frame 13 is in a "mouth" - shaped structure connected end to end.

[0033] Among them, each aluminum alloy frame 10 includes two vertical sections and two horizontal sections. The vertical sections are arranged along the length direction of the door leaf frame 13 or the door frame 2, and the horizontal sections are arranged along the width direction of the door leaf frame 13 or the door frame 2. Specifically, as Figure 6As shown, the vertical and horizontal sections of the aluminum alloy frame 10 are fixedly connected by corner brackets 8; the corner brackets 8 include two fixing sides with a right angle between them, and the fixing sides are attached to the inner cavity side walls of the aluminum alloy frame 10 and then fixed by bolts.

[0034] In order to improve the heat insulation performance of the aluminum alloy frame 10, in this embodiment, as Figure 7 shown, the aluminum alloy frame 10 includes a first frame 101 and a second frame 102. Among them, the first frame 101 and the second frame 102 are arranged along the normal direction of the door leaf 1, and the first frame 101 and the second frame 102 are connected by a plurality of heat insulation strips 9. Specifically, the heat insulation strips 9 are connected to 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, avoiding contact between the first frame 101 and the second frame 102, thereby reducing heat conduction between the inner and outer sides of the door leaf 1 through the aluminum alloy frame 10, and thus improving the heat insulation performance of the door leaf 1 and the door frame 2.

[0035] Specifically, an insulation space 100 is also formed between two adjacent heat insulation strips 9. Here, the insulation space 100 can be empty to reduce the weight of the door leaf 1, thereby reducing the stress on the top and bottom shafts 1000 and reducing the risk of the door leaf 1 sagging; or insulating materials can be filled in the insulation space 100 to further improve the heat insulation performance of the door leaf 1 and the door frame 2.

[0036] As Figure 5 and Figure 8 shown, the door leaf body 12 includes an aluminum plate 121, a sealing and blocking edge 122, a sealing plate 123, and honeycomb aluminum 124. Among them, the cross-section of the sealing and blocking edge 122 is C-shaped, and two sets of sealing and blocking edges 122 are arranged inside the door leaf frame 13. The sealing and blocking edge 122 is in contact with the vertical section of the door leaf frame 13. Two sets of sealing and blocking edges 122 are arranged along the width direction of the door leaf 1. Among them, the honeycomb aluminum 124 is arranged between two adjacent sealing and blocking edges 122 to strengthen the strength of the door leaf 1. Sealing plates 123 are arranged on both sides of the sealing and blocking edge 122 to encapsulate the honeycomb aluminum 124. It should be noted that the sealing plates 123 are arranged along the normal direction of the door leaf 1. Among them, the aluminum plate 121 is attached to the outside of the door leaf frame 13 to decorate the door leaf 1.

[0037] After the door leaf 1 is installed on the door frame 2 through the top and bottom shafts 1000, there is a gap between the door leaf 1 and the door frame 2. The existence of this gap will also affect the heat preservation performance of the offset-axis door.

[0038] To solve this problem, the utility model patent with the authorization announcement number CN222478492U cited in the background art discloses a technical solution, which uses an air charging and discharging component to perform air charging and discharging treatment on the first sealing component, enabling the first sealing component to switch between a bulging state and a shriveled state, thereby achieving the sealing after the door leaf 1 is closed. In the shriveled state, it is convenient for the door leaf 1 to rotate relative to the door frame 2, so as to open the offset door.

[0039] This technical solution performs air inflation or deflation treatment on the first sealing component through the air charging and discharging 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, it is necessary to manually control the air charging and discharging component to inflate, so that the first sealing component remains in a bulging state, causing the first sealing component to expand and compensate for the gap space; when it is necessary to open the door leaf, it is necessary to manually control the air charging and discharging component to deflate, so that the first sealing component is in a shriveled state to facilitate opening the door leaf 1.

[0040] However, during the normal use of the offset door, when a person opens the door, they can directly pass through the door frame. When the person leaves, they will manually push the door to rotate, thereby switching the door leaf 1 to the closed state. At this time, the person will directly leave. However, in the solution disclosed in the above document, it is necessary to manually control the air charging and discharging component to inflate before leaving, which is different from people's activity habits and will cause discomfort when closing the door.

[0041] Therefore, in this application, the solution for blocking the gap between the door leaf 1 and the door frame 2 is improved to suit people's door closing habits.

[0042] As Figure 9 shown, it includes a first sealing part 3 and a driving part 4 for driving 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. After the driving part 4 pushes the first sealing part 3 outwards to the extended state, the extended first sealing part 3 can block the gap between the door leaf 1 and the door frame 2, thereby achieving the sealing between the door leaf 1 and the door frame 2, improving the heat insulation performance of the offset door, and reducing the influence of the existence of the gap on the heat insulation performance of the offset door.

[0043] 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 completely sinks into the interior of the door leaf 1. When the first sealing part 3 is in the extended state, the first sealing part 3 partially extends into the door frame 2, thereby achieving the sealing of the gap between the door leaf 1 and the door frame 2.

[0044] It is also worth noting that four groups of the first sealing parts 3 can be provided. Among them, the four groups of the first sealing parts 3 are connected end to end and arranged at the side position of the door leaf 1. When the four groups of the first sealing parts 3 extend simultaneously, they can completely block the gap between the periphery of the door leaf 1 and the door frame 2.

[0045] Further, two sets of first sealing portions 3 may be provided. The two sets of first sealing portions 3 are arranged along the height direction of the door leaf 1 and are respectively arranged at the top and bottom of the door leaf 1. The first sealing portion 3 is used to block the gaps between the door leaf 1 and the top and bottom of the door frame 2. There are also two sets of second sealing portions 7, as Figure 8 shown. The two sets of second sealing portions 7 are arranged along the width direction of the door leaf 1 to block the gaps between the door leaf 1 and the sides of the door frame 2.

[0046] In order to control the state of the first sealing portion 3, as Figure 9 shown, there is also a locking assembly 5 and an unlocking portion 6. Among them, as Figure 10 shown, the unlocking portion 6 includes an unlocking transmission member 61 and an unlocking driving member 62. The locking assembly 5 is arranged on the side of the first sealing portion 3. The unlocking transmission member 61 is connected to the locking assembly 5. One of the unlocking transmission member 61 and the unlocking driving member 62 is installed on the door leaf 1, and the other is installed on the door frame 2. When the first sealing portion 3 retracts into the door leaf 1, the locking assembly 5 is used to limit the movement of the first sealing portion 3, thereby restricting the first sealing portion 3 from switching to the extended state. When the door leaf 1 needs to be opened, the unlocking driving member 62 is used to drive the unlocking transmission member 61 to move, and then the unlocking transmission member 61 drives the locking assembly 5 to move, so that the locking assembly 5 releases the locking of the first sealing portion 3. At this time, the driving portion 4 pushes the first sealing portion 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 portion 3 is inserted into the door frame 2, so as to realize the sealing of the gap between the door leaf 1 and the door frame 2.

[0047] In order to install the first sealing portion 3, in this embodiment, as Figure 11 shown, the horizontal sections at the top and bottom of the door leaf frame 13 are also made of aluminum alloy frames 10. Specifically, the horizontal sections here include a first frame 101 and a second frame 102 arranged along the normal direction of the door leaf 1. The first frame 101 and the second frame 102 of the horizontal sections at the top and bottom are connected by a heat insulation strip 9. Among them, the aluminum alloy frame 10 at the top forms an installation groove 11 with an upward opening, and the aluminum alloy frame 10 at the bottom forms an installation groove 11 with a downward opening. Among them, the first sealing portion 3 is slidably installed in the installation groove 11, and the first sealing portion 3 can slide along the height direction of the door leaf 1.

[0048] Specifically, as Figure 12As shown in the figure, the first sealing portion 3 includes a seal 31 and a sliding member 32. Among them, the first sealing portion 3 is strip-shaped and extends along the width direction of the door leaf 1. The seal 31 and the sliding member 32 are integrally formed. Among them, the cross-section of the first sealing portion 3 is in a "T" shape. The side wall of the sliding member 32 abuts against the side wall of the installation groove 11, and a gap is left between the side wall of the seal 31 and the side wall of the installation groove 11 for the locking assembly 5 to buckle the sliding member 32, so that the first sealing portion 3 is maintained in the retracted state.

[0049] In order to improve the sealing effect of the gap between the door leaf 1 and the door frame 2, in this embodiment, when the door frame 2 is of a "mouth" shape, embedding grooves 21 are provided on both the upper retaining edge 22 and the lower threshold 23 of the door frame 2. When the offset door is closed, at this time the first sealing portion 3 is in the extended state, as Figure 13 shown, the seal 31 extends out of the door leaf 1 and extends into the corresponding embedding groove 21 to improve the sealing effect of the gap.

[0050] When the door frame 2 adopts a "U" - shaped structure with the opening facing downwards, at this time, an embedding groove 21 is provided on the upper retaining edge 22 of the door frame 2. When the offset door is closed, at this time, the first sealing portion 3 at the top of the door leaf 1 is inserted into the embedding groove 21 on the retaining edge 22, as Figure 13 shown, at this time, the first sealing portion 3 at the bottom of the door leaf 1 extends downwards and abuts against the ground, thereby sealing the gap between the door leaf 1 and the ground.

[0051] In order to lock the first sealing portion 3, in this embodiment, as Figure 12 shown, the locking assembly 5 includes a locking buckle 51. Locking grooves 103 communicating with the installation groove 11 are provided on the side walls of the first frame 101 and the second frame 102 at the horizontal section at the top of the door leaf 1. Among them, the locking buckle 51 is rotatably installed in the inner cavities of the first frame 101 and the second frame 102 through a rotating shaft 52, as Figure 14 shown, the locking buckle 51 further includes a locking head 511. Among them, the locking head 511 can extend into the installation groove 11 through the locking groove 103. By using the abutment of the locking head 511 against the top wall of the sliding member 32, the first sealing portion 3 can be maintained in the retracted state.

[0052] In order to be able to switch the first sealing portion 3 from the retracted state to the extended state, in this embodiment, as Figure 14As shown, at this time, the locking buckle 51 is further provided with a flipping part 512, and the unlocking transmission part 61 is connected to the flipping part 512. Among them, the connection point of the unlocking transmission part 61 and the flipping part 512 deviates from the axis of the rotating shaft 52, so that the locking buckle 51 can be flipped around the rotating shaft 52, so that the locking head 511 is flipped into the inner cavity of the first frame 101 or the second frame 102, and the locking of the locking head 511 on the sliding part 32 is released. At this time, the first sealing part 3 can be switched from the retracted state to the extended state under the action of the driving part 4.

[0053] Specifically, as Figure 14 shown, the flipping part 512 is provided with a flipping rod 513 extending along the width direction of the door leaf 1, and the unlocking transmission part 61 is rotatably connected to the flipping rod 513.

[0054] In order to be able to drive the first sealing part 3 to switch between the retracted state and the extended state, in this embodiment, as Figure 15 shown, the driving part 4 includes a driving plate 41, a traction rope 42, a handle 43, a torsion spring 44 and a compression spring 45. Among them, the compression spring 45 is installed in the installation groove 11. One end of the compression spring 45 abuts against the inner wall of the installation groove 11, and the other end of the compression spring 45 abuts against the sliding part 32. The elastic deformation of the compression spring 45 is used to store energy to provide power for the movement of the first sealing part 3. The driving plate 41 is rotatably installed in the heat insulation space 100 formed by the first frame 101 and the second frame 102 on the vertical section of the door leaf 1. The handle 43 is located outside the door leaf 1, and the handle part of the handle 43 is connected to the driving plate 41 to drive the driving plate 41 to rotate. One end of the traction rope 42 is fixedly connected to the sliding part 32, and the other end of the traction rope 42 is connected to the driving plate 41. One end of the torsion spring 44 is connected to the driving plate 41, and the other end of the torsion spring 44 is connected to the door leaf 1; among them, the connection point of the traction rope 42 and the driving plate 41 deviates from the rotation axis of the driving plate 41. When the first sealing part 3 is in the extended state, the traction rope 42 is in a taut state.

[0055] Specifically, the process of opening the door leaf 1 is as follows. By manually pressing the handle 43, the driving plate 41 is driven to rotate. At this time, the first sealing part 3 is dragged from the extended state to the retracted state through the traction rope 42. When the first sealing part 3 moves into the installation groove 11, the first sealing part 3 releases the locking of the door leaf 1 and the door frame 2, and the door leaf 1 is pushed to rotate around the vertical shaft 1000, thereby opening the door. At this time, the locking assembly 5 is buckled back into the installation groove 11 again under the reset of the unlocking transmission part 61, as Figure 12 shown, the locking of the first sealing part 3 is realized by the locking head 511 on the locking buckle 51. At this time, the restriction on the handle 43 can be released, and the handle 43 and the driving plate 41 are reset under the action of the torsion spring 44.

[0056] It should be noted here that the handle 43 is installed on the vertical section of the door leaf frame 13 on the side away from the vertical and horizontal axis 1000, and the connection point of the traction rope 42 and the sliding member 32 is located at the center of the bottom wall of the sliding member 32, so that the sliding member 32 is more evenly stressed and it is convenient to realize the traction of the first sealing portion 3.

[0057] Here, if the traction rope 42 is directly used to connect the sliding member 32 and the driving plate 41, at this time, the bending angle of the traction rope 42 is relatively large, which is not convenient for the operation of the traction rope 42. Therefore, in this embodiment, as Figure 15 shown, the driving portion 4 further includes a stabilizing block 46 and a traction rod 47. Among them, the stabilizing block 46 is arranged in the heat insulation space 100 of the vertical section of the door leaf frame 13, and the side wall of the stabilizing block 46 is slidably connected to the inner wall of the heat insulation space 100 along the longitudinal direction of the door leaf 1. One end of the traction rod 47 is rotatably connected to the driving plate 41, and the other end of the traction rod 47 is rotatably connected to the stabilizing block 46. It should be noted that the connection point of the traction rod 47 and the driving plate 41 deviates from the rotation axis of the driving plate 41, and the traction rope 42 is connected to the stabilizing block 46.

[0058] To facilitate the connection between the handle 43 and the driving plate 41, as Figure 16 shown, it further includes a transmission rod 48. The cross section of the transmission rod 48 is rectangular. The transmission rod 48 passes through the driving plate 41 so that the driving plate 41 can rotate following the transmission rod 48. The handle portion of the handle 43 is directly inserted into the transmission rod 48, thereby realizing the connection between the handle 43 and the driving plate 41.

[0059] In order to release the locking of the first sealing portion 3 by the locking buckle 51, in this embodiment, as Figure 17 and Figure 18As shown in the figure, the unlocking transmission member 61 includes a positioning frame 611, a sliding block 612, a spring 613, a first magnet 614, and a transmission mechanism 615. Among them, the positioning frame 611 is fixedly installed in the heat insulation space 100 of the vertical section of the door leaf frame 13 through bolts. The sliding block 612 is slidably installed in the inner cavity of the positioning frame 611 and moves along the width direction of the door leaf 1. One end of the spring 613 is connected to the sliding block 612, and the other end of the spring 613 is connected to the inner wall of the inner cavity of the positioning frame 611. The first magnet 614 is fixedly installed on the sliding block 612, and one end of the transmission mechanism 615 is connected to the flipping rod 513. The unlocking driving member 62 is installed on the door frame 2. When the offset door is in the closed state, at this time, the unlocking driving member 62 is aligned with the first magnet 614 on the sliding block 612, so as to drive the sliding block 612 to move toward the unlocking driving member 62 inside the door frame 2 through the first magnet 614 and compress the spring 613. At this time, the sliding block 612 drives the flipping part 512 to flip through the transmission mechanism 615, so that the locking buckle 51 rotates around the rotating shaft 52, so as to release the buckling state between the locking head 511 and the sliding member 32, so as to facilitate the switching of the first sealing part 3 from the retracted state to the extended state.

[0060] Specifically, as Figure 17 shown, the transmission mechanism 615 includes 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 longitudinally along the front. The first rod 6151 is slidably connected to the sliding block 612. The second rod 6152 is horizontally arranged and connected to the end of the first rod 6151 away from the sliding block 612. There are two groups of the third rods 6153, and one end of the third rod 6153 is rotatably connected to the second rod 6152, and the other end of the third rod 6153 is rotatably connected to the flipping rod 513.

[0061] Among them, as Figure 19 shown, there are two groups of inclined slots 6121 on the sliding block 612. The two groups of inclined slots 6121 form a horizontally placed "eight" shape. Among them, the side with the larger opening faces the spring 613, and the side with the smaller opening faces the vertical shaft 1000. The end of the first rod 6151 is inserted into the inclined slot 6121 and forms a sliding connection.

[0062] Through the above settings, when the sliding block 612 is attracted by the unlocking driving member 62, the sliding block 612 moves toward the unlocking driving member 62 and compresses the spring 613. At this time, the first rod 6151 is pulled by the inclined slot 6121 to move toward the middle position of the sliding block 612 of the door leaf 1. The middle position here is relative to the up and down directions, so as to drive the locking buckle 51 to flip through the second rod 6152, the third rod 6153, and the flipping rod 513, so as to realize the switching of the state of the locking assembly 5.

[0063] Specifically, as Figure 20As shown, a vertically arranged through hole 461 is provided on the stabilizing block 46. 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 using the sliding fit 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 accidental unlocking of the locking buckle 51 can be reduced.

[0064] It should be noted that the unlocking driving member 62 includes a second magnet 621. As Figure 10 and Figure 18 shown, the second magnet 621 is fixedly installed in the door frame 2, and the second magnet 621 and the first magnet 614 are at the same height.

[0065] There are two sets of locking buckles 51, which are respectively located on both sides of the first sealing portion 3 to improve the stability of locking the first sealing portion 3.

[0066] There are two sets of third rods 6153, which are respectively connected to the locking buckles 51 on both sides of the first sealing portion 3 to realize the synchronous operation of the locking buckles 51 on both sides of the first sealing portion 3.

[0067] When the door leaf 1 is opened, the door leaf 1 is misaligned with the door frame 2. At this time, the second magnet 621 releases the attraction on the first magnet 614, and the spring 613 pushes the sliding block 612 to move away from the second magnet 621. At this time, the first rod 6151 is pushed away from the sliding block 612, so that the locking buckle 51 can be reset, and the locking head 511 is inserted into the installation groove 11.

[0068] When the door leaf 1 is opened, if the first sealing portion 3 is in the extended state for other reasons, when the door leaf 1 rotates around the top and bottom shaft 1000 to the closed state, the first sealing portion 3 will contact the edge 22 of the door frame 2, thus restricting the closing of the door leaf 1. Therefore, it is necessary to manually switch the first sealing portion 3 to the retracted state. The first solution is as Figure 14 shown. A guiding inclined surface 5111 is provided at the top of the locking head 511. By rotating the handle 43, the traction rope 42 retracts the first sealing portion 3 into the installation groove 11 at this time. During this process, the side wall of the sliding member 32 first abuts against the guiding inclined surface 5111 of the locking head 511. As the first sealing portion 3 moves downward, the locking head 511 rotates around the rotating shaft 52, moves the sliding member 32 to the lower side of the locking head 511. Finally, the locking head 511 is reset, and the locking head 511 is buckled with the top wall of the sliding member 32 to switch the first sealing portion 3 to the retracted state.

[0069] The second solution is, as Figure 19As shown, a reset groove 6122 is provided on the side wall of the sliding block 612, and a tooth groove 6123 is provided on the bottom wall of the reset groove 6122. It further includes a gear 616, which is installed in the reset groove 6122. The gear 616 meshes with the tooth groove 6123 in the reset groove 6122. A reset rod 617 passes through the door leaf 1 and is rotatably connected to the gear 616. By rotating the reset rod 617, the gear 616 is driven to rotate, so as to push the sliding block 612 to move towards the unlocking driving member 62 and compress the spring 613, thereby driving the locking buckle 51 to rotate through the transmission mechanism 615 to be in a state of releasing the locking of the first sealing portion 3. At this time, the first sealing portion 3 is retracted into the installation groove 11 through the handle 43. Then the reset rod 617 is released. At this time, the locking buckle 51 resets, and the first sealing portion 3 is locked through the locking head 511. Then the handle 43 is released.

[0070] As Figure 10 shown, the second sealing portion 7 includes a first sealing group 71, a second sealing group 72, and a third sealing group 73. Among them, the second sealing portion 7 is arranged in the gap between the door leaf 1 and the side of the door frame 2. Here, the side of the door frame 2 and the door leaf 1 refers to the vertical section of the aluminum alloy frame 10. The first sealing group 71, the second sealing group 72, and the third sealing group 73 are arranged in sequence along the normal direction of the door leaf 1 to form three layers of seals in the gap between the door leaf 1 and the door frame 2, improving the sealing effect of the gap between the door leaf 1 and the door frame 2.

[0071] Specifically, the distribution of the second sealing portion 7 at the gap between the door leaf 1 and the door frame 2 on the side far from the floor hinge 1000 is introduced here. The first sealing group 71, the second sealing group 72, and the third sealing group 73 are arranged in sequence from inside to outside. For the second sealing portion 7 at the gap between the door leaf 1 and the door frame 2 on the side close to the floor hinge 1000, the first sealing group 71, the second sealing group 72, and the third sealing group 73 are arranged in sequence from outside to inside. Here, "inside" refers to "indoors", and "outside" refers to "outdoors".

[0072] Here, a detailed description of the distribution of the second sealing portion 7 in the gap between the door leaf 1 and the door frame 2 on the side far from the floor hinge 1000 is as Figure 21 shown. The first sealing group 71 includes a first sealing member 711. Among them, the first sealing member 711 is inserted into the side of the first frame 101 on the door leaf 1. The first sealing member 711 is provided with a pushing edge 7111 and a buffer edge 7112. Among them, the pushing edge 7111 abuts against the side wall of the first frame 101 of the door leaf 1. The first frame 101 on the door frame 2 is provided with a limiting edge 1011. When the door leaf 1 is closed, the buffer edge 7112 of the first sealing member 711 abuts against the limiting edge 1011 of the first frame 101 on the door frame 2 to form the first seal, thereby restricting the door leaf 1 from continuing to rotate around the floor hinge 1000.

[0073] AsFigure 22 As shown, the second sealing group 72 includes a first sealing strip 721 and a second sealing strip 722. Among them, the first sealing strip 721 is installed between the first frame 101 and the second frame 102 of the door leaf 1, and the second sealing strip 722 is installed between the first frame 101 and the second frame 102 of the door frame 2. A sealing flange 7211 extending toward the door frame 2 is provided on the inner side of the first sealing strip 721 near the door leaf 1, and a sealing buffer edge 7221 extending toward the door leaf 1 is provided on the inner side of the second sealing strip 722 away from the door leaf 1. When the door leaf 1 is closed, the sealing buffer edge 7221 abuts against the sealing flange 7211 to form a second seal.

[0074] As Figure 23 shown, the third sealing group 73 includes a third sealing member 731. Among them, the third sealing member 731 is inserted into the second frame 102 of the door frame 2, and a sealing rubber strip area 7311 arranged obliquely is provided at the cross section of the third sealing member 731. When the door leaf 1 is closed, the second frame 102 of the door leaf 1 abuts against the sealing rubber strip area 7311 of the third sealing member 731.

[0075] In summary, when the offset door is closed, the door leaf 1 and the door frame 2 are aligned. At this time, the buffer edge 7112 of the first sealing member 711 abuts against the limit stop edge 1011 of the first frame 101 of the door frame 2, the sealing flange 7211 of the first sealing strip 721 abuts against the sealing buffer edge 7221 of the second sealing strip 722, and the third sealing member 731 abuts against the second frame 102 on the door leaf 1, thereby realizing triple sealing of the side gap between the door leaf 1 and the door frame 2.
