Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of door and window hardware, and particularly relates to a lifting type sliding door and window. BACKGROUND

[0002] A door or a window is a basic component of a modern building, and is mainly divided into a horizontally opening type door and window and a sliding type door and window according to the opening mode of the door and window. Among them, the sliding type door and window is mainly composed of a door or window leaf and a track, that is, the door or window leaf moves back and forth along the track to realize the opening or closing of the door and window. At the same time, since it is flexible to open, it can form a partition in space and will not occupy extra space when opening, so the sliding type door and window is a relatively more commonly used type of door and window, for example, used between a balcony and a living room to form a partition, and for example, used between a kitchen and a dining room.

[0003] However, the sliding type door and window in the prior art has certain inconvenience in use. Specifically, in order to facilitate the sliding door to be fixed or positioned on the track at any time as needed during use, for example, to prevent young children in the home from entering and leaving the balcony at will under the condition of ensuring basic ventilation, a lifting type hardware appears on the market, and its main working principle is that the pulley block on the door and window can be extended or retracted by a certain distance relative to the leaf body of the door and window, that is, the leaf body of the door and window can be lifted or lowered by a certain distance relative to the track, thereby forming a lifting type sliding door and window. Further, when the pulley block is retracted relative to the track or the sliding groove, that is, the leaf body of the door and window falls (descends) on the track, so that the leaf body of the door and window forms static friction with the track, thereby positioning the leaf body of the door and window on the fixed track or on the track, for example, a European standard C slot lifting sliding door and window hardware disclosed in application No. 201720561394.7. However, when the leaf body of the door and window is closing, especially the heavy lifting type sliding door and window with relatively large inertia during its closing process, since the lifting and lowering timing of the pulley block cannot be accurately controlled, or the moving speed of the door and window leaf body cannot be accurately controlled, the leaf body of the door and window often collides with the outer frame and rebounds, thereby failing to be smoothly closed, and thus the lifting type sliding door and window in the prior art has the above-mentioned problem of inconvenience in use.

[0061] The technical solutions of the present application will be described in further detail below with reference to the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it. However, the embodiments are not intended to limit the present application. In the embodiments, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0062] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated as a whole, or there can be a middle element. The terms "mount", "one end", "the other end", and the like used in the present application are only for the purpose of illustration.

[0063] As shown in Figures 1-16 The present embodiment provides a lifting sliding door window, which comprises a frame 18, a sash 19, a transmission box 20 and a pulley mechanism. The sash 19 is installed in the frame 18 and can move reciprocally along the frame 18. Further, the bottom of the frame 18 is provided with a track (not shown) for the movement of the sash 19. The transmission box 20 and the pulley mechanism are installed on the sash 19. The transmission box 20 is used to drive and control the position of the pulley mechanism relative to the sash 19, i.e., to make the rollers 9 of the pulley mechanism extend from the bottom of the frame 18, and in turn to make the sash 19 be in a lifted state relative to the frame 18, that is, to make the sash 19 be able to walk in the frame 18 through the pulley mechanism. Further, the lifting sliding door window further comprises a retreat-stopping assembly, which comprises a first mechanism and a second mechanism that cooperate with each other. The first mechanism is installed on the sash 19. The transmission box 20 is in transmission connection with the first mechanism and the pulley mechanism, and both the transmission box 20 and the first mechanism are installed on one side of the sash 19. Of course, a handle 21 is also installed on the transmission box 20, which is used to drive the transmission box 20, and the transmission box 20 is in transmission connection or linkage with the first mechanism. Further, the second mechanism is installed on the frame 18, and the second mechanism corresponds to and cooperates with the first mechanism. When the sash 19 is in the closing process, the first mechanism and the second mechanism form a touch, and the first mechanism and the second mechanism are in touch and form interlocking, so that the sash 19 is positioned relative to the frame 18.

[0064] Further, by setting the first mechanism on the fan body 19 and the second mechanism on the frame body 18, when the fan body 19 moves in the frame body 18 and collides with one side of the frame body 18 (closed), the first mechanism on the fan body 19 and the second mechanism on the frame body 18 are in contact (the first mechanism triggers the second mechanism), and then the first hook on the first mechanism and the second hook on the second mechanism are locked, avoiding the fan body rebounding (retaining) due to the impact of the frame body during closing, that is, improving the convenience of the lifting sliding door window.

[0065] As shown in Figure 14 , Figure 15 , Figure 16 In the preferred embodiment, the transmission box 20 is provided with a trigger mechanism, which is triggered by external force, and then the transmission box releases the lifting state of the fan body 19 relative to the frame body 18; that is, when the fan body 19 collides with one side of the frame body 18 during closing, the trigger mechanism on the transmission box 20 is triggered, and then the fan body 19 falls onto the frame body 18 or the track of the frame body 18, and at this time the fan body 19 and the frame body 18 or the track form a static friction. Further, when the fan body of the door window collides with the frame body during closing, if the impact force is relatively large (the rebound potential energy is relatively large), the fan body may still rebound a certain distance relative to the frame body, and the retaining assembly can further eliminate this problem. At the same time, since the transmission box 20 is in transmission connection with the first mechanism, when the transmission box 20 is triggered, the locking of the first mechanism and the second mechanism is also released, that is, the fan body 19 is prevented from being lifted and moved relative to the frame body 18 by driving the transmission box through the handle again, and the fan body 19 and the frame body 18 are still in a certain locked state.

[0066] As shown in Figures 10-16As shown, in particular, the lifting sliding door and window in the use process will exist as follows several situations: the first case, relative to the door and window frame 18, when the need to close the door and window fan 19, at this time in the control of the transmission box 20, located at the bottom of the fan 19 roller 9 relative to the second base 7 in the state of extension, that is, the roller 9 on the fan 19 has been lifted, and then make the fan 19 can be along the frame 18 bottom rail free movement (transverse direction); when the movement of the fan 19 and with the side wall of the frame 18 collision (the first mechanism installed on the fan 19, the second mechanism installed on the frame 18), the first hook body 3 on the first mechanism end and the second hook body 15 on the second mechanism, further, because the first hook body 3 and the second hook body 15 end respectively set up each other mutually matched with the slope, therefore, with the fan continues to move, the first hook body 3 will force the second hook body 15 to slide up (the second hook body 15 is fixed on the fourth slider 14, and the fourth slider 14 and the third base 13 sliding connection) and compression second reset spring 16, when the first hook body 3 of the end of the second hook body 15 end, under the elastic force of the second reset spring 16, push the fourth slider 14 and the second hook body 15 downward movement, and then make the first hook body 3 and the second hook body 15 end dislocation, that is, the first mechanism and the second mechanism form locking, or said to be the fan 19 and the frame 18 form locking, so as to avoid the fan 19 because of the collision to the frame 18 and form the rebound. Further, after the collision of the fan 19 and the frame 18, trigger and make the transmission box unlock, that is, to release the lifting state of the first mechanism on the roller 9, and the fan 19 then fall on the frame 18, and then complete the fan 19 relative to the frame 18 of the closing state.

[0067] Further, when the end of the first hook body 3 and the end of the second hook body 15, located on the first mechanism on the length direction of the end face or said end of the block 4 and located on the second mechanism on the protruding block 17, at this time, the block 4 is extruded and retracted to the third slider 2; further, after the collision of the fan 19 and the frame 18, trigger and make the transmission box unlock, that is, to release the lifting state of the first mechanism on the roller 9, the fan 19 relative to the bottom of the frame 18 fall, and then with the block 4 relative to the block 17 fall, when the end of the block 4 sweep the block 17, under the elastic force of the first reset spring 6, push the block 4 relative to the third slider 2 (in the transverse direction) extension.

[0068] The second case, relative to the frame 18 of the door and window, when the door and window need to be opened, the handle 21 drives the transmission box 20 to move, the transmission box 20 further drives the first mechanism, that is, the roller 9 is extended from the bottom of the door and window or the door and window is lifted relative to the bottom of the frame 18; the frame 18 drives the block 4 to move upward and drives the convex block 17 to move upward, and further drives the fourth sliding block 14 and the second hook body 15 installed on the fourth sliding block 14 to move upward, so as to avoid the first hook body 3 and the second hook body 15 on the door and window from being locked; that is, if the first hook body 3 and the second hook body 15 are locked at this time, the door and window cannot be opened.

[0069] Further, when the door and window 19 moves in the transverse direction until the end of the block 4 sweeps the end of the convex block 17, the fourth sliding block 14 and the second hook body 15 are reset under the elastic force of the second reset spring 16, so as to facilitate the relocking of the first hook body 3 and the second hook body 15 in the next closing process of the door and window 19, that is, to avoid the door and window 19 from rebounding due to impact on the frame 18 in the closing process.

[0070] As Figures 1-9As shown, in the preferred embodiment, the transmission box comprises a housing 22, a driving mechanism, a lifting frame 23 and a trigger mechanism; the lifting frame 23 is in sliding connection with the housing 22, the driving mechanism is connected with the housing 22, and the driving mechanism is in transmission connection with the lifting frame 23, the trigger mechanism is connected with the housing 22, and the trigger mechanism is in transmission connection with the lifting frame 23, the driving mechanism is used to drive the lifting frame 23 to move along the axial direction or the length direction of the housing 22, or in other words, the lifting frame 23 moves up and down relative to the housing 22. Of course, the driving mechanism is also connected with a square shaft and a handle matched with the square shaft, that is, the user applies a torque to the square shaft through the handle, and then the driving mechanism finally drives the lifting frame 23 to move relative to the housing 22; according to the viewing angle of the views in the embodiment, the lifting frame 23 moves upward relative to the housing 22. Further, after the lifting frame 23 moves to the preset position relative to the housing 22, that is, after the lifting frame 23 moves to the upper dead point relative to the housing 22, the trigger mechanism is activated and the lifting frame 23 is in a locked state relative to the housing 22, that is, the lifting frame 23 is locked by the trigger mechanism at this time so that it cannot move downward relative to the housing 22; further, the purpose of the upward movement of the lifting frame 23 is to drive the pulley assembly installed at the bottom of the fan body to work, so that the pulley in the pulley assembly extends relative to the fan body (the fan body is in a lifted state relative to the frame body) and forms a walking part of the fan body in the frame, that is, the fan body can move freely along the frame. Further, when the trigger mechanism is activated, it is in a state of being triggered, and when the trigger mechanism is triggered by external force, the trigger mechanism releases the locking state of the lifting frame 23 relative to the housing 22, that is, the lifting frame 23 can move downward along the housing 22 at this time.

[0071] Specifically, when the transmission box is installed on the lifting sliding door and window, the door and window panel is in the process of closing, the side of the door and window panel touches or collides with the frame, and then the trigger mechanism is started and the locking state of the lifting frame 23 is released; further, the gravity of the door and window itself will be conducted in the opposite direction to the lifting frame 23 through the pulley, that is, the lifting frame 23 will move downward along the shell 22 at this time, or the lifting frame 23 is reset relative to the shell 22 at this time. Further, since the lifting frame 23 loses control of the pulley assembly, it will fall back to the bottom of the frame or the track at the bottom of the frame under the action of its own gravity, so that the panel and the frame or the track form static friction, that is, to avoid the panel rebounding relative to the frame due to the impact of the panel on the outer frame, that is, to make the door and window cannot be closed smoothly, thereby improving the convenience of using the sliding door and window. Further, when the panel of the door and window needs to be positioned at a specific position of the frame, the trigger mechanism can be directly pressed and started by hand at this time, so that the panel falls on the frame and the panel cannot move freely along the frame; for example, when there is a child in the room, the opening of the door and window needs to be maintained for safety consideration, at this time the above operation can be performed.

[0072] As Figure 5 , Figure 8 , Figure 9As shown in the preferred embodiment, the driving mechanism comprises a pull rod 24 and a driving wheel 25, the driving wheel 25 penetrates through and is rotationally connected with the shell 22, that is, the driving wheel 25 can rotate relative to the shell 22. Further, the driving wheel 25 is also provided with a square shaft hole for connecting a square shaft, and the handle is connected to the square shaft, that is, a torque is applied to the square shaft through the handle to drive the transmission box to perform corresponding actions through the driving mechanism; of course, in addition to the square shaft (the cross section of the shaft is rectangular), other types of shafts such as spline shafts and triangular shafts can also be used as long as the torque of the handle can be transmitted to the transmission box. The first end of the pull rod 24 is connected with the lifting frame 23, and the pull rod 24 is used to transmit the power of the driving wheel 25 and pull the lifting frame 23 to move relative to the shell 22; the second end of the pull rod 24 is hingedly connected with the driving wheel 25 through a pin shaft, and the second end of the pull rod 24 deviates from the axis of the driving wheel 25 or the hinge point of the pull rod 24 and the driving wheel 25 deviates from the rotation axis of the driving wheel. When the driving wheel 25 rotates, the hinge point of the pull rod 24 and the driving wheel 25 revolves relative to the rotation axis point of the driving wheel 25, thereby driving the lifting frame 23 to move upward relative to the shell 22. Further, the lifting frame 23 is also provided with one or more limiting holes 49, and the shell 22 is provided with a second limiting piece 50 which penetrates through the lifting frame 23 and is fixed with the shell 22 by riveting or welding or bolt fastening. The limiting hole 49 is strip-shaped, and the axis of the limiting hole 49 is parallel to the axis of the lifting frame 23. The limiting hole 49 and the second limiting piece 50 which cooperates therewith are used to limit the up-down movement stroke of the lifting frame 23 relative to the shell 22.

[0073] As shown in the preferred embodiment, Figure 5 , Figure 8 , Figure 9 As shown in the preferred embodiment, the driving mechanism further comprises a power assisting mechanism, and the power assisting mechanism is in transmission connection with the lifting frame 23. The power assisting mechanism is used to reduce the initial input torque of the driving mechanism. Specifically, the power assisting mechanism comprises a guide wheel 26 and a first protrusion 27. One end of the first protrusion 27 is integrally formed with the driving wheel 25, and the other end of the first protrusion 27 is a lifting end. The end face of the lifting end is a bevel or an arc face. One end of the bevel or the arc face in the length direction forms a smooth transition with the peripheral surface of the driving wheel 25. The peripheral surface refers to the circumferential surface of the driving wheel 25. The other end of the bevel or the arc face extends away from the axis of the driving wheel 25. The bevel or the arc face gradually rises relative to the radial direction (the longitudinal direction in the figure) of the driving wheel 25, or in other words, the bevel or the arc face gradually rises from one end to the other end in the longitudinal direction of the shell 22. Further, the guide wheel 26 is rotationally connected with the lifting frame 23 through a pin shaft, and the guide wheel 26 abuts against the end face of the lifting end of the first protrusion 27.

[0074] Further, in the axial direction relative to the housing 22, the lateral or horizontal distance from the shaft center of the guide wheel 26 to the shaft center of the drive wheel 25 is less than the lateral or horizontal distance from the shaft center of the drive wheel 25 to the second end of the pull rod 24; the transmission box is mainly used to control the movement of the pulley assembly relative to the fan body during use, that is, to control and enable the fan body to be lifted to a certain height relative to the track of the frame (for example, the fan body is lifted to a height of about 5MM relative to the track), so that the friction between the fan body and the track is converted from static friction (when the fan body falls on the track) to rolling friction (the pulley assembly as a walking part of the fan body). Since the transmission box needs to control and enable the fan body to be lifted or lifted to a certain distance relative to the track, the pull rod 24 needs to have a certain length base, and the weight base of the door and window fan body is often relatively large, especially for window bodies using double-layer glass; therefore, in the initial state of the door and window, it is relatively laborious to control the lifting of the fan body by the handle (a large force or torque is required), at this time, simply increasing the length of the handle (equivalent to increasing the length of the lever) to achieve labor saving when the door and window is opened, will make the length of the handle and the proportion of the door and window fan body very uncoordinated. Further, in the setting of the power assisting mechanism, the lateral distance or horizontal distance (length) from the shaft center of the guide wheel 26 to the shaft center of the drive wheel 25 is less than the lateral distance or horizontal distance (length) from the shaft center of the drive wheel 25 to the second end of the pull rod 24, that is, the cooperation of the guide wheel 26 and the first protrusion 27 is equivalent to shortening the length of the resistance arm from the shaft center of the drive wheel 25 to the first end of the pull rod 24, in other words, it is to increase the length of the power arm on the basis of the unchanged length of the handle, and further to realize the labor saving operation of the transmission box.

[0075] As Figure 5 , Figure 8 , Figure 9As shown, in the preferred embodiment, the driving wheel 25 rotates beyond a preset angle, such as 35 degrees, relative to the housing 22, and the guide wheel 26 and the lifting end are separated from each other. Specifically, when the driving wheel 25 rotates to a certain angle, such as 35 degrees, the distance (length) from the axis of the guide wheel 26 to the axis of the driving wheel 25 is less than the distance (length) from the axis of the driving wheel 25 to the second end of the pull rod 24, which is nearly equal. That is, the lifting moment of the power-assisted mechanism (through the first protrusion 27) acting on the lifting frame 23 is nearly equal to the lifting moment of the driving wheel 25 (through the pull rod 24) acting on the lifting frame 23, or reaches a balance point. That is, the power-assisted mechanism has completed its purpose of labor-saving operation. Further, with the view angle as the reference, when the lifting moment of the power-assisted mechanism and the driving mechanism acting on the lifting frame 23 reaches a relative balance point, if the first protrusion 27 still needs to participate in power assistance at this time, the width of the first protrusion 27 needs to be increased to maintain the extension (length of the inclined surface or arc surface) of the end surface of the lifting end. This will increase the volume of the driving wheel 25, and in order to accommodate the driving wheel 25, the volume of the lifting frame 23 and the housing 22 will also be increased accordingly (the lifting frame 23 and the housing 22 need to be matched in the width direction).

[0076] As shown, Figures 5-9 In the preferred embodiment, the trigger mechanism includes a locking assembly and an unlocking assembly. The locking assembly is connected to the housing 22, and the locking assembly and the lifting frame 23 cooperate with each other to make the lifting frame 23 in a locked state relative to the housing 22. The unlocking assembly is connected to the lifting frame 23, and the unlocking assembly is in transmission connection with the locking assembly. The unlocking assembly is used to release the locking state of the lifting frame 23 by the locking assembly.

[0077] Specifically, the locking assembly comprises a first guide post 28, a third sliding block 29, a first return spring 30, a limiting block 31, a first guide slot 32, a second guide slot 33, and a second protrusion 34 arranged on the third sliding block 29, of course, the second protrusion 34 can also be directly regarded as the third sliding block 29. The first guide post 28 is fixed with the shell 22 by riveting, welding or screwing, the third sliding block 29 is in sliding connection with the first guide post 28, and the third sliding block 29 can reciprocate along the axial direction or the length direction (the transverse direction) of the first guide post 28. In the embodiment, the first guide post 28 is provided with two, and the first guide post 28 penetrates the third sliding block 29 in the transverse direction. One end of the first return spring 30 abuts against the third sliding block 29, and the other end of the first return spring 30 abuts against the shell 22. The limiting block 31 is fixed with the third sliding block 29 by welding, screwing or interference fit. The second protrusion 34 is located at the bottom end of the third sliding block 29, one end of the second protrusion 34 is fixed with the third sliding block 29, and in the embodiment, the second protrusion 34 is integrally formed with the third sliding block 29. The other end of the second protrusion 34 is a free end. After the second protrusion 34 is subjected to an external force, the third sliding block 29 is driven to move along the axial direction (the transverse direction) of the first guide post 28.

[0078] Further, the first guide slot 32 and the second guide slot 33 are both arranged on the lifting frame 23, the first guide slot 32 and the second guide slot 33 form an included angle of 90 degrees, or the axis of the first guide slot 32 and the axis of the lifting frame 23 form an included angle of 90 degrees. In the embodiment, the first guide slot 32 is arranged transversely relative to the lifting frame 23, the second guide slot 33 is arranged longitudinally relative to the lifting frame 23, and one end of the first guide slot 32 and the second guide slot 33 is communicated, that is, the first guide slot 32 and the second guide slot 33 form a straight angle shaped hole on the lifting frame 23. The limiting block 31 can move along the first guide slot 32 or the second guide slot 33. When the lifting frame 23 is locked with the shell 22, the limiting block 31 is moved from the second guide slot 33 to the first guide slot 32. After the lifting frame 23 is unlocked with the shell 22, the limiting block 31 is moved from the first guide slot 32 to the second guide slot 33. Specifically, since the lifting frame 23 can only move along the axial direction (up and down) of the shell 22, when the third sliding block 29 drives the limiting block 31 to move (transversely) into the first guide slot 32 of the lifting frame 23, and since the axis of the first guide slot 32 and the axis of the lifting frame 23 form an included angle of 90 degrees, at this time in the longitudinal direction, the limiting block 31 prevents and makes the lifting frame 23 unable to move downward relative to the shell 22, that is, it is locked. Further, when the third sliding block 29 drives the limiting block 31 to move (transversely) into the first guide slot 32 and the second guide slot 33 of the lifting frame 23, at this time the axis of the second guide slot 33 is parallel to the lifting frame 23 relative to the shell 22, so that the lifting frame 23 can move downward along the shell 22, that is, the lifting frame 23 is unlocked.

[0079] like Figures 5-9 As shown, in a preferred embodiment, the unlocking assembly includes a second guide post 35, a second slider 36, a trigger block 37, a second reset spring 38, a third reset spring 39, and a first lever 40. Further, the second guide post 35 is fixed to the lifting frame 23 by riveting, bolting, or welding. The second slider 36 is slidably connected to the second guide post 35, and the second slider 36 can reciprocate along the axial direction of the second guide post 35. In this embodiment, two first guide posts 35 are provided, and the second guide posts 35 penetrate the second slider 36 in the transverse direction. Further, one end of the second reset spring 38 abuts against the second slider 36, and the other end abuts against the lifting frame 23. One end of the trigger block 37 is fixedly connected to the second slider 36. In this embodiment, the trigger block 37 and the second slider 36 are integrally formed, and the other end of the trigger block 37 is a free end or trigger end. The second reset spring 38 is used to push the second slider 36 and cause the free end of the trigger block 37 to extend outside the housing 22. Furthermore, the first lever 40 is located at the top of the second slider 36. Relative to the axial direction of the second slider 36, the first lever 40 is slidably connected to the second slider 36. One end of the third return spring 39 abuts against the first lever 40, and the other end abuts against the second slider 36. The third return spring 39 is used to make the end of the first lever 40 extend out of the second slider 36. The first lever 40 is used to move the first protrusion 27 and drive the third slider 29 to move along the axial or length direction of the first guide post 28.

[0080] Specifically, when the lifting frame 23 is locked relative to the housing 22, the end of the first lever 40 abuts against the free end of the first protrusion 27, and the trigger block 37 is located inside the housing 22; when the transmission box is installed on the lifting sliding door and window, when the fan body is closed relative to the frame, that is, the trigger block 37 is compressed by the frame and retracts into the housing 22; furthermore, when the fan body needs to be opened, since the fan body is falling on the frame, that is, the fan body cannot move freely left and right along the frame, that is, it is necessary to input torque to the transmission box through the handle and finally make the frame body lift relative to the fan body through the pulley assembly. When the fan body is lifted, that is, the lifting frame 23 of the transmission box is locked to the housing 22, and the fan body can be moved through the pulley assembly. Furthermore, as the fan moves (one side of the fan moves away from the frame), the trigger block 37 is no longer squeezed by the frame. Under the push of the second return spring 38, the trigger block 37 extends out of the housing 22 (the second return spring 38 pushes the second slider 36 and drives the trigger block 37 to move). As the second slider 36 moves, in the radial direction along the first lever 40, the end of the first lever 40 brushes past the free end of the first protrusion 27, and the end of the first lever 40 is in a suspended state. At this time, under the push of the elastic force of the third return spring 39, the end of the first lever 40 extends upward out of the second slider 36, so that one side of the first lever 40 corresponds to one side of the first protrusion 27; that is, the trigger block 37 is in an active state at this time. That is, when the trigger block 37 is squeezed, the locking state between the lifting frame 23 and the housing 22 can be released, thereby releasing the control of the pulley assembly, and thus causing the fan to fall onto the frame or the track of the frame.

[0081] like Figures 8-9 As shown, in a preferred embodiment, a reset component is also provided on the drive mechanism. The reset component is mounted on the lifting frame 23 and is connected to the drive mechanism in a transmission manner. After the drive mechanism drives and locks the lifting frame 23 relative to the housing 22, the reset component pushes the drive mechanism to reset. The reset component can reset the handle after the door and window opening and closing operation is completed, avoiding the problem that the door and window sash will output reverse power to the handle under the action of gravity after the trigger block 37 of the transmission box is triggered and unlocked, that is, drive the handle to rotate in the opposite direction, which may cause the handle to hit or twist the user's hand.

[0082] Specifically, the reset assembly comprises a rack 41 and a fourth reset spring 42, the rack 41 is in sliding connection with the shell 22, and the rack 41 can move along the axial direction or the length direction or the up-down direction of the lifting frame 23 and / or the shell 22, one end of the fourth reset spring 42 is in abutment with the lifting frame 23, and the other end is in abutment with the rack 41, and the driving wheel 25 of the driving mechanism is further provided with a gear ring 43, the gear ring 43 is in engagement with the rack 41, because the rotation angle of the driving wheel 25 does not exceed 360 degrees, therefore, the gear ring 43 in the embodiment only covers part of the area (minor arc) in the circumferential direction of the driving wheel 25. Further, the lifting frame 23 is further provided with a third guide slot 45, the third guide slot 45 is arranged in the longitudinal direction, or the axis of the third guide slot 45 is consistent with the arrangement direction of the axis of the lifting frame 23; the first end of the pull rod 24 of the driving mechanism is further provided with a pull rod shaft 44, the pull rod shaft 44 is arranged in the third guide slot 45; after the driving mechanism is reset, the pull rod shaft 44 moves from the first end of the third guide slot 45 to the second end of the third guide slot 45, that is, when the locking of the lifting frame 23 is released, the lifting frame 23 moves downward along the shell 22, or, when the lifting frame 23 moves downward along the shell, the pull rod shaft 44 relative to the third guide slot 45 is a sliding process, that is, at this time, the lifting frame 23 does not drive the pull rod shaft 44 to move synchronously, that is, the rotation of the handle driven synchronously by the lifting frame 23 moving downward is avoided.

[0083] As Figures 8-9As shown, in the preferred embodiment, the driving mechanism is further provided with a driving wheel locking mechanism, when the driving mechanism drives the lifting frame 23 to move along the axial direction or length direction or up-down direction of the housing 22, (by the trigger mechanism) the lifting frame 23 is in the locked state relative to the housing 22, or the lifting frame 23 is in the unlocked state relative to the housing 22, and (after the torque applied on the handle is removed) the reset assembly pushes the driving mechanism to reset, the driving wheel locking mechanism locks the driving wheel 25; further, after the trigger mechanism releases the locking of the lifting frame 23, the driving wheel locking mechanism releases the rotation locking of the driving wheel 25. The driving wheel locking mechanism can further improve the safety of the transmission box; assuming that in the locked state of the lifting frame 23 relative to the housing 22, the handle can still be rotated, that is, the driving wheel 25 on the transmission box rotates; further, in the state of rotating the handle by a certain angle, if the lifting frame 23 is unlocked by the trigger block 37 at this time, under the action of the gravity of the door and window leaf body, the handle will be inevitably driven to rotate in the opposite direction, which may cause the user's hand to be sprained or the handle to hit the user's body. Further, assuming that in the state of rotating the handle by a certain angle, the pull rod shaft 44 at this time will move between the two ends of the third guide groove 45, that is, the height of the pull rod shaft 44 in the longitudinal direction is increased, thereby interfering with the movement stroke of the third guide groove 45, that is, when the lifting frame 23 moves downward, the pull rod shaft 44 will be dragged to move downward until the stop point, and the pull rod shaft 44 will drag the driving wheel 25 to rotate in the opposite direction through the pull rod 24.

[0084] Specifically, the driving wheel locking mechanism comprises a rocker arm 46, a fifth return spring 47 and a guide 48. The guide 48 in the embodiment is a rotatable wheel body. The rocker arm 46 is hinged to the lifting frame 23. The fifth return spring 47 is located on one side of the lifting frame 23. One end of the fifth return spring 47 abuts against the rocker arm 46, and the other end abuts against the lifting frame 23. The guide 46 is located at the first end of the rocker arm 46, and the end surface of the first end of the rocker arm 46 is obliquely arranged. Further, when the lifting frame 23 is in the locked state relative to the housing 22, the fifth return spring 47 pushes the rocker arm 46 to deflect relative to the housing 22, so that the second end of the rocker arm 46 corresponds to the end of the rack 41 (in the axial direction), so that the rack 41 is in the locked state relative to the housing 22, and the end surface of the first end of the rocker arm 46 corresponds to the guide 48. At this time, if the handle is rotated, the handle will drive the driving wheel 25 to rotate, and further, the gear ring 25 on the driving wheel 25 will drive the rack 41 to move downward along the housing 22. Since the second end of the rocker arm 46 corresponds to the end of the rack 41 at this time, the rack 41 moves downward, that is, the handle connected to the driving wheel cannot be rotated, thereby improving the safety of the lifting sliding door and window during use. Further, the locking state of the lifting frame 23 relative to the housing 22 is triggered and released, and during the falling and resetting of the lifting frame 23 relative to the housing 22, since the end surface of the first end of the rocker arm 46 is inclined, the rocker arm 46 will be forced to deflect relative to the guide 48, or in other words, the guide 48 will push and make the rocker arm 46 deflect relative to the housing 22, so that the second end of the rocker arm 46 is separated from the end of the rack 41, that is, the second end of the rocker arm 46 will not limit the upward and downward movement of the rack 41 at this time.

[0085] As shown in Figures 10-13 , the stop assembly comprises a first mechanism mounted on the curtain. The first mechanism comprises a first base 1, a fifth sliding block 2 and a first hook body 3. The fifth sliding block 2 is slidably connected to the first base 1, and the fifth sliding block 2 can reciprocate along the axial direction of the first base 1. The first hook body 3 is fixed to the fifth sliding block 2 by bolts or rivets, or the first hook body 3 is integrally formed with the fifth sliding block 2. Further, after the fifth sliding block 2 moves to a first position relative to the first base 1, the first hook body 3 can be locked with an external mechanism, which is referred to as a second mechanism. Further, after the fifth sliding block 2 moves to a second position relative to the first base 1, the first hook body 3 is unlocked with the external mechanism.

[0086] As shown in Figures 10-11As shown, in a preferred embodiment, the fifth slider 2 is further provided with a lever 4, which is spaced apart from the first hook 3. In this embodiment, in the backward direction, the lever 4 is located below the first hook 3. The lever 4 is slidably connected to the fifth slider 2, and the lever 4 can reciprocate in the radial direction relative to the first base 1. The lever 4 is used to move the external component. Further, the fifth slider 2 is provided with a slide rail 5 and a first return spring 6. The lever 4 and the first return spring 6 are both placed in the slide rail 5. One end of the first return spring 6 abuts against the fifth slider 2, and the other end abuts against the first end of the lever 4. The second end of the lever 4 can extend or retract in the slide rail 5. That is, when the second end of the lever 4 is subjected to an axial compressive force, the lever 4 compresses the first return spring 6 and retracts into the fifth slider 2. Conversely, when the compressive force applied to the lever 4 is removed, under the elastic force of the first return spring 6, the second end of the lever 4 extends relative to the fifth slider 2. That is, the first return spring 6 makes the lever 4 extend relative to the fifth slider 2. Furthermore, the first hook 3 and the lever 4 are both located on the same side of the fifth slider 2.

[0087] like Figures 10-11 As shown, in a preferred embodiment, the pulley mechanism is fixedly connected to the first mechanism, and the fifth slider 2 is drivenly connected to the pulley mechanism. Furthermore, by drivingly connecting the fifth slider 2 to the pulley mechanism, synchronous linkage between the first mechanism and the pulley mechanism can be achieved, thereby simplifying the structural composition of the lifting sliding door / window. In another embodiment, when the length of the door / window sash is relatively large, one or more additional pulley mechanisms can be used as extension pulley mechanisms. The extension pulley mechanisms fix the bottom of the sash 19, and are spaced apart from the pulley mechanisms connected to the first mechanism, thus providing reliable support for the sash. Furthermore, the structure of the extension pulley mechanism is basically the same as the main structure of the pulley mechanism connected to the first mechanism, the main difference being that the extension pulley mechanism does not have a drive arm 12. Furthermore, the extension pulley mechanism and the pulley mechanism are connected in series for transmission.

[0088] like Figures 10-11 As shown, in a preferred embodiment, the pulley mechanism includes a second base 7, a bracket 8, a roller 9, a first connecting rod 10, and a second connecting rod 11; wherein the second base 7 and the first base 1 are fixed by bolts, riveting, or welding. Furthermore, since the pulley mechanism needs to serve as a moving component of the door / window sash 19, it must be installed at the bottom of the sash 19, while the first mechanism, as a component of the anti-reverse mechanism, needs to be installed on one side of the sash 19. That is, the first base 1 in the first mechanism and the second base 7 on the pulley mechanism need to form an angle. Since the door / window sash 19 is typically rectangular, in this embodiment, the first base 1 and the second base 2 form a 90-degree angle, allowing the first base 1 and the second base 2 to be located on opposite sides of the door / window sash 19.

[0089] Further, the first connecting rod 10 and the second connecting rod 11 are arranged in parallel, the first ends of the first connecting rod 10 and the second connecting rod 11 are hingedly connected to the bracket 8 through a pin shaft, the second ends of the first connecting rod 10 and the second connecting rod 11 are hingedly connected to the second base 7 through a pin shaft, the roller 9 is connected to the bracket 8, and the first connecting rod 10 is further provided with a driving arm 12, the first end of the driving arm 12 is integrally formed with the first connecting rod 10, the second end of the driving arm 12 extends away from the first connecting rod 10, and the second end of the driving arm 12 is hingedly connected to the fifth sliding block 2. Further, the driving arm 12 is used to drive the bracket 8 to move in the radial direction relative to the second base 7, after the fifth sliding block 2 moves to the first position relative to the first base 1, the bracket 8 drives the roller 9 to move away from the second base 7, and after the fifth sliding block 2 moves to the second position relative to the first base 1, the bracket 8 drives the roller 9 to move close to the second base 7; in the use process, the driving arm 12 is hingedly connected to the lower end of the fifth sliding block 2, that is, the movement of the fifth sliding block 2 drives the bracket 8 and the roller 9 to move in the radial direction relative to the second base 7, that is, the lifting of the roller 9 realizes the lifting of the door and window sash 19.

[0090] Further, the hingedly connected points of the first connecting rod 10, the second connecting rod 11, the second base 7 and the bracket 8 jointly form a parallelogram, that is, the axes of the first connecting rod 10 and the second connecting rod 11 are parallel to each other, and the axes of the second base 7 and the bracket 8 are parallel to each other. Further, according to the movement characteristics of the parallelogram mechanism (the axes of the two opposite sides always remain parallel, and the angular displacement, angular velocity and angular acceleration of the two connecting rods always remain equal), the roller 9 connected to the bracket 8 is lifted or lowered relative to the second base 5 or the sash 19 of the door and window, that is, after the roller 9 extends relative to the sash 19, the bottom of the sash 19 is separated from the frame, that is, at this time, the friction between the sash 19 and the frame changes from static friction to rolling friction (the roller 9 and the frame), so that the sash can move freely along the frame, that is, the opening or closing operation of the sash relative to the frame is realized. In addition, the roller 9 can be more than one, such as 2, 3 or more; for example, in the embodiment, the roller 9 installed on the bracket 8 is two, and the rollers 9 are arranged in parallel along the length direction of the bracket 8, that is, when multiple rollers 9 are arranged, the carrying capacity of the pulley mechanism can be improved.
