[0034] Referring to FIGS. 1-7, a door and window that can be opened in opposite directions includes a window frame 1 fixedly connected to a wall, a window sash 2 that can be opened and closed connected to the window frame 1, the window sash 2 including a sash frame 22 and glass, preferably hollow glass, which has better heat and sound insulation performance, a connecting piece, the number of which is at least two, having a left opening state and a right opening state, the window sash 2 being connected to the window frame 1 through the connecting piece, and a control handle 3 provided on the window sash 2 or the window frame 1, preferably the control handle 3 is provided on the window sash 2; wherein the control handle 3 can control the state switching of the connecting piece, so that the two opposite sides of the window sash 2 can be opened alternatively. Specifically, the embodiment can be set to open in the up-down or left-right direction according to the needs, and only one direction can be opened when opened.

[0035] Compared with the existing door and window that only supports single-side opening, the embodiment provides a design scheme that can be opened in opposite directions. This design allows users to flexibly choose which side of the door and window to open according to the actual use environment. For example, the user can choose to close the windward side and open the leeward side to reduce the impact of wind pressure on the door and window; or when the air intake is too large or too small, the other side is opened; or when privacy needs to be considered, the side to be opened is selected according to the actual situation, thereby improving the flexibility and convenience of use.

[0036] The connecting member can be a sliding support 4 or a hinge. When the connecting member is a sliding support 4, left and right sliding supports 4 can be arranged above and below the window sash 2, preferably symmetrically arranged at both ends of the window sash 2. When the window sash 2 needs to be opened to the left, the right sliding support 4 is locked and connected with the window sash 2 by controlling the handle 3, and the left sliding support 4 is disconnected with the window sash 2, in this state, the window sash 2 can be opened to the left in the left opening state of the connecting member. When the window sash 2 needs to be opened to the right, the window sash 2 needs to be closed first, and then the state of the connecting member is switched by controlling the handle 3, so that the connecting member is switched to the state opposite to that when the window sash 2 is opened to the left, and the window sash 2 can be opened to the right. It can be understood that the left and right sliding supports 4 can share a supporting rod 41 and a window rail rod 42, that is, the left and right sliding supports 4 are designed as one sliding support 4; the control handle 3 can be one or two, when the control handle 3 is two, the left and right sliding supports 4 are controlled respectively.

[0040] The detachable structure has a disengaged position and a connected position, and the control handle 3 can control the connection between the connection member and the window frame 1 or the sash 2. Specifically, when the left connection member of the sash 2 is in the disengaged position and the right connection member is in the connected position, the sash 2 can be opened on the side of the left connection member, that is, the sash 2 can be disengaged from the left connection member, and the sash 2 is supported to be opened by the connection with the right connection member. By switching the gear of the control handle 3, the opening on the other side can be realized.

[0041] In some embodiments, locking members 5 are further included, and the locking members 5 are provided on at least two opposite sides of the sash 2 and the window frame 1. Preferably, the locking members 5 are provided on the two opposite sides and symmetrically arranged at the two ends of a single side. The locking member 5 includes a locking point 51 fixedly connected to the window frame 1 and a lock post 52 movably arranged on the sash 2. When the sash 2 is in the closed state, the lock post 52 is locked with the locking point 51; when the sash 2 is in the opened state, the lock post 52 is disengaged from the locking point 51. The lock post 52 is in a columnar shape, and in the closed state of the sash 2, the lock post 52 protrudes towards the window frame 1. The locking point 51 is fixedly connected to the window frame 1 and is provided with a lock block 53 extending towards the lock post 52. The lock block 53 is arranged outside the lock post 52 and has an inwardly recessed arc surface. In the closed state of the sash 2, the lock block 53 can limit the opening of the sash 2. When it is needed to open the embodiment, the control handle 3 can be switched to the opening gear (the gear of one side or the other side), at which time the lock post 52 is driven by the transmission member, the lock post 52 is disengaged from the locking point 51, and the sash 2 can be pushed out to be opened.

[0042] In some embodiments, the connection member is a sliding support 4, and the sliding support 4 is provided with a detachable structure and is arranged at the two ends of the bottom and / or top of the sash 2.

[0044] Referring to FIG. 5, the sliding support 4 comprises a window frame 1 connected to the window frame 1, and a window frame 2 connected to the window frame 2, and the window frame 2 is connected to the window frame 2 by a hinge connection, wherein the window frame 2 or the window frame 2 is provided with a detachable structure, the detachable structure comprises a locking part 43 and a disengaging part 44, the detachable structure can be locked / disengaged with the window frame 1 or the window frame 2. In this embodiment, the detachable structure is provided on the window frame 2, and the window frame 2 can be locked / disengaged with the window frame 2. The window frame 2 has a bending part 45 arranged along the length direction of the window frame 2, which can strengthen the strength of the window frame 2. Specifically, the window frame 2 has a card column 21, which is movably arranged on the window frame 2, and the card column 21 is controlled by the handle 3 to switch the gear to control the card column 21, so that the card column 21 moves to the locking part 43 or the disengaging part 44, and the sliding support 4 can be disengaged with the window frame 2 when the card column 21 moves to the disengaging part 44. In this embodiment, the sliding support 4 is divided into left and right sliding supports 4, which are connected to the two sides of the window frame 2 respectively, and when one of the sliding supports 4 is disengaged with the window frame 2, the other sliding support 4 is connected to the window frame 2, and in this state, the window frame 2 can be opened on one side. Similarly, the handle 3 is used to switch the connection state of the left and right sliding supports 4 with the window frame 2, and the other side of the window frame 2 can be opened.

[0045] The sliding support 4 of this embodiment has a detachable structure. Through this innovative design, the sliding support 4 can be easily disengaged or connected with the window frame 2 or the window frame 1, thereby realizing the function that both sides of the window frame 2 can be independently opened.

[0046] In some embodiments, the detachable structure is provided on the window frame 2. With such design, the sliding support 4 can be disengaged with the window frame 2, and the window frame 2 can be opened without taking the sliding support 4 out.

[0058] Referring to FIGS. 6 and 7, in some embodiments, a limiting lock box 6 is further included, which comprises a shell 61 and limiting members 62 oppositely arranged at both ends of the shell 61, the limiting members 62 being movably connected to the shell 61, the limiting members 62 comprising locking portions 63 and pushed portions 64; the sliding support 4 comprises a left opening sliding support 4 and a right opening sliding support 4, the sliding support 4 comprising a window edge rod 42 connected with the window frame 1 and a supporting rod 41 connected with the window sash 2, the supporting rod 41 and the window edge rod 42 being connected with a hinge connecting member, the detachable structure being arranged on the supporting rod 41, the supporting rod 41 and the window edge rod 42 being provided with limiting portions 411 at the ends far away from each other in the opened state of the sliding support 4, the limiting portions 411 being matched with the locking portions 63, when the locking portions 63 are locked with the limiting portions 411 on one side, the opening of the sliding support 4 can be limited.

[0059] Specifically, the limiting lock box 6 comprises a shell 61 and limiting members 62 oppositely arranged at two ends of the shell 61, the limiting members 62 are movably connected to the shell 61, the limiting members 62 comprise locking portions 63 and pushed portions 64, wherein when the pushed portions 64 are subjected to external force, the locking portions 63 corresponding to the pushed portions 64 can move towards or away from the shell 61, and when the external force is removed, the locking portions 63 can reset. In this embodiment, the limiting members 62 are slidably connected to the shell 61, the locking portions 63 are used to engage with the limiting portions 411 of the slide 4 to limit the opening of the slide 4, and the pushed portions 64 are used to receive external force to engage or disengage the locking portions 63 with the limiting portions 411 to limit the movement of the slide 4. The external force can be from the limiting strip 74, the limiting strip 74 is provided with a force applying member 741, the force applying member 741 pushes the pushed portions 64 to engage or disengage the locking portions 63 with the limiting portions 411. Preferably, the limiting lock box 6 is in engagement with the limiting portions 411 in the normal state to limit the movement of the slide 4.

[0060] The limiting lock box 6 of this embodiment has simple structure, low error rate and high reliability, and the slides 4 are arranged on both sides of the limiting lock box 6, and only one side of the slide 4 can be changed to limit the limiting state of the limiting lock box 6, and the limiting state of the slides 4 on both sides cannot be changed at the same time.

[0061] It can be understood that the limiting lock box 6 can not only be used to limit the slide 4, but also be used to limit other movable members.

[0062] In some embodiments, the limiting members 62 are two, arranged at two ends of the shell 61, and the pushed surfaces 65 of the pushed portions 64 are oppositely arranged, and when the external force acts on the pushed surfaces 65, the locking portions 63 corresponding to the pushed surfaces 65 move towards the shell 61. Specifically, the pushed portions 64 are provided with pushed surfaces 65, the pushed surfaces 65 of the two pushed portions 64 are oppositely arranged, the force applying member 741 of the limiting strip 74 is arranged between the two pushed surfaces 65, and when the force applying member 741 moves, only one of the pushed surfaces 65 can be pushed. In this embodiment, when the pushed portions 64 are not pushed, the corresponding locking portions 63 engage with the limiting portions of the slide 4 to limit the opening of the slide 4. Such design of this embodiment can prevent the slides 4 on both sides from being opened at the same time.

[0063] In some embodiments, a force applying member 741 is further included for pushing the pushed surface 65, the force applying member 741 can move between the two pushed surfaces 65 and push the pushed surface 65; the space between the two pushed surfaces 65 is the extension space 66, and the force applying member 741 does not abut against the pushed surfaces 65 on both sides when it is in the middle position of the extension space 66. Specifically, the distance between the two pushed surfaces 65 is greater than the width of the force applying member 741, so that the force applying member 741 does not contact the pushed surfaces 65 on both sides when it is in the middle position. The space between the two sides is the extension space 66, and the stroke of the force applying member 741 is greater than the stroke of the limiting member 62, that is, the limiting member 62 cannot be pushed when the force applying member 741 starts to move, and the limiting member 62 can be pushed to move only after the force applying member 741 moves a certain stroke. Such design can prevent the limiting member 62 from being locked or disengaged with the sliding support 4 when the control handle 3 is not completely switched to the gear position.

[0064] In some embodiments, the two limiting members 62 are arranged in a staggered manner, and the locking portions 63, the pushed portions 64 and the force applying member 741 at both ends are located on a straight line. Specifically, the locking portions 63 at both ends have corners and protrude outwardly from the housing 61, and the limiting members 62 are arranged in a staggered manner, the pushed surfaces 65 at both ends are arranged oppositely, and the force applying member 741 is arranged between the two pushed surfaces 65, and the pushed surfaces 65, the locking portions 63 and the force applying member 741 move on the same straight line. Such design is more reasonable in stress and is not easy to slip.

[0065] In some embodiments, a limiting structure is arranged between the locking portion 63 and the pushed portion 64, and when the pushed portion 64 of one of the limiting members 62 is pushed, the limiting structure can limit the movement of the other limiting member 62. Specifically, the movement path of the pushed portion 64 of one limiting member 62 overlaps with the movement path of the locking portion 63 of the other limiting member 62, and when the pushed portion 64 is pushed, it can block the movement of the locking portion 63 of the other limiting member 62.

[0066] In some embodiments, the limiting structure includes a limiting surface one 67 arranged on the pushed portion 64 and a limiting surface two 68 arranged on the locking portion 63, and the movement trajectories of the limiting surface one 67 and the limiting surface two 68 have overlapping portions. Specifically, the limiting surface one 67 and the limiting surface two 68 are arranged oppositely, and when viewed in the transverse direction, the limiting surface one 67 and the limiting surface two 68 have overlapping projection areas. This embodiment has higher safety, and the locking portion 63 can be controlled only on one side, and the resetting failure of the locking portion 63 can be prevented.

[0067] In some embodiments, the shell 61 comprises a bottom shell and an upper cover covering the top of the bottom shell, the limiting piece 62 is slidingly connected inside the bottom shell, and the elastic piece 69 is arranged between the limiting piece 62 and the shell 61.
