Transmission lock box and overhead sliding door window

Abstract

The present application relates to the technical field of doors and windows, and discloses a transmission lock box and a lifting type sliding door and window, wherein the transmission lock box comprises a mounting shell, a liftable lifting frame is arranged in the mounting shell, a driving assembly for driving the lifting frame to lift along the length direction of the lifting frame is arranged in the lifting frame, the driving assembly is in transmission along the length direction of the lifting frame, and part of the driving assembly is connected with the mounting shell after penetrating through the lifting frame. Since the driving assembly is in transmission along the length direction of the lifting frame, the transverse space (i.e. the width direction of the lifting frame or the mounting shell) of the lifting frame and the mounting shell is not occupied, so the volume of the mounting shell can be reduced to adapt to the profile cavity of an extremely narrow profile, i.e. the thickness and width direction space of the profile cavity is not occupied, and the length direction space of the extremely narrow profile is fully utilized.

Description

Technical Field

[0001] This invention relates to the field of door and window technology, and particularly to a transmission lock box and a lift-type sliding door and window having the transmission lock box. Background Technology

[0002] Lift-up sliding doors and windows are a common type of door and window in modern buildings. Their characteristic is that they can be lifted upwards when opened, without occupying indoor or outdoor space. This type of door and window is usually more user-friendly, and the opening method can be flexibly adjusted according to needs, improving the convenience of use.

[0003] Lift-up sliding doors and windows can be either lift-up sliding doors or lift-up sliding windows. They typically include a frame profile mounted on a wall and a sash profile that slides back and forth on the frame profile. A handle, a transmission lock box connected to the handle, a transmission assembly connected to the transmission lock box, and a pulley assembly connected to the transmission assembly are installed on the sash profile. The sash profile is supported on the frame profile by the pulley assembly and can slide back and forth on the frame profile via the pulley assembly. However, existing transmission lock boxes typically use a crank-pull rod drive mechanism, which requires a large space in the lateral direction (i.e., the width direction of the lock box). Therefore, the volume of the transmission lock box needs to be increased to provide sufficient installation space for the drive mechanism. This results in an increase in the overall volume of the transmission lock box. Correspondingly, the cavity space of the sash profile used to install the transmission lock box also needs to be increased, leading to an increase in the overall volume of the sash profile. This makes the sash profile bulky and, moreover, affects the indoor lighting effect. To address the aforementioned issues, the industry has introduced ultra-narrow profiles, which in turn require a transmission lock box that can be installed within these profiles. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a transmission lock box suitable for extremely narrow profiles, and a lift-type sliding door and window having the transmission lock box.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solutions:

[0006] The present invention discloses a transmission lock box, including a mounting housing, a liftable lifting frame disposed inside the mounting housing, and a drive component disposed inside the lifting frame to drive the lifting frame to move up and down along its length direction. The drive component drives along the length direction of the lifting frame, and a portion of the drive component passes through the lifting frame and is connected to the mounting housing.

[0007] The transmission lock box of this invention is installed in the profile cavity on the side of the fan profile, with the mounting housing connected to the profile cavity. The handle's rotating shaft passes through the wall of the profile cavity and is inserted into the drive assembly. Rotating the handle drives the rotating shaft, which in turn drives the drive assembly along the length of the lifting frame. This allows the lifting frame to rise and fall along its length under the action of the drive assembly. Since the lifting frame is sequentially connected to the transmission assembly and the pulley assembly, the rising and falling of the lifting frame drives the rising and falling of the transmission assembly and the pulley assembly. Finally, the pulley assembly lifts or lowers the fan profile. Because the drive assembly moves along the length of the lifting frame, it does not occupy the lateral space of the lifting frame and the mounting housing (i.e., the width direction of the lifting frame or mounting housing). Therefore, the volume of the mounting housing can be reduced to accommodate the profile cavity of extremely narrow profiles, i.e., it does not occupy the thickness and width space of the profile cavity, fully utilizing the length space of the extremely narrow profile.

[0008] Furthermore, the drive assembly includes a rotating member rotatable relative to the lifting frame and the mounting housing. The rotating member includes a rotating part and a drive part connected to the rotating part. The drive part extends in a direction away from the rotating part, and the distance between the two side walls of the drive part is equal to or less than the diameter of the rotating part. A first transmission tooth is provided at the end of the drive part. The drive assembly also includes a first horizontal moving member rotatable relative to the lifting frame. A second transmission tooth is provided on the end face of the first horizontal moving member facing the rotating member. A first motion trajectory surface is provided on the end face of the first horizontal moving member away from the rotating member. The first motion trajectory surface includes a first horizontal segment, a second horizontal segment, and an inclined segment. The first horizontal segment and the second horizontal segment are connected through the inclined segment. The first transmission tooth and the second transmission tooth mesh with each other. The drive assembly also includes a top shaft connected to the lifting frame and located above the first horizontal moving member, and in contact with the first motion trajectory surface on the first horizontal moving member.

[0009] Furthermore, the transmission lock box also includes at least two first guide shafts spaced apart in the vertical direction. The two ends of the first guide shafts are connected to the mounting housing. The first horizontal moving member is sleeved on all the first guide shafts and can slide horizontally back and forth relative to the first guide shafts.

[0010] Furthermore, in the horizontal movement direction of the first horizontal moving member, a first return spring is provided between the first horizontal moving member and the mounting housing.

[0011] Furthermore, a child lock safety component is also provided inside the lifting frame; the child lock safety component includes a second horizontally movable component that can move elastically horizontally and at least two second guide shafts spaced apart in the vertical direction. The two ends of the second guide shafts are connected to the mounting housing. The second horizontally movable component is sleeved on all the second guide shafts and can move horizontally back and forth relative to the second guide shafts. A positioning shaft passes through the second horizontally movable component along its thickness direction. An L-shaped hole is provided on the side wall of the lifting frame. The positioning shaft extends out of the second horizontally movable component and into the L-shaped hole. A second through hole is also provided on the lifting frame. A portion of the second horizontally movable component passes through the second through hole on the lifting frame and then extends out to the outside of the mounting housing.

[0012] Furthermore, in the horizontal movement direction of the second horizontal moving member, a second return spring is provided between the second horizontal moving member and the mounting housing.

[0013] Furthermore, a gear is provided below the second horizontal moving member, and a third through hole is provided in the middle of the gear. Multiple spiral grooves are provided at intervals on the inner wall of the third through hole. The child lock safety component also includes a rotating member, which includes a rotating part that cooperates with the third through hole and a connecting part connected to the rotating part. A pressing part is connected to the connecting part. Multiple spiral protrusions are provided at intervals on the side wall of the rotating part. When the rotating member is installed in the third through hole, the spiral protrusions are embedded in the corresponding spiral grooves. A third transmission tooth is provided on the side of the second horizontal moving member facing the gear, and the third transmission tooth meshes with the gear.

[0014] The present invention also provides a lift-type sliding door and window, including a frame profile and a sash profile that can reciprocate on the frame profile. The aforementioned transmission lock box is installed in a profile cavity on the side of the sash profile. The mounting housing of the transmission lock box is connected to the profile cavity wall of the sash profile. The lifting frame of the transmission lock box is sequentially connected to a transmission locking assembly and a pulley assembly. The transmission locking assembly is configured to drive and connect or separate from the frame profile to drive the pulley assembly to move and to lock or allow the sash profile to slide. The pulley assembly is configured to slide along the frame profile and lift or lower the sash profile.

[0015] The lifting sliding door and window described in this invention has all the beneficial technical effects brought about by the aforementioned transmission lock box, which will not be elaborated here.

[0016] Furthermore, the transmission locking assembly includes a transmission rod and a locking component. One end of the transmission rod is connected to the lifting frame in the transmission lock box, and the other end is indirectly connected to the sliding and pulley assembly. The locking component includes a locking pin mounting seat and a locking pin insertion seat. The locking pin mounting seat is installed in the profile cavity of the fan profile and sleeved on the transmission rod. The locking pin insertion seat is connected in the profile cavity of the frame profile and is disposed opposite to the locking pin mounting seat. A locking pin is provided on the locking pin mounting seat, and a locking hole for the locking pin to be inserted is provided on the locking pin insertion seat. In the locked state, the locking pin is inserted into the locking hole and is restricted by the locking hole and cannot be disengaged from the locking hole. In the open state, the locking pin is not restricted by the locking hole and can be disengaged from the locking hole.

[0017] Furthermore, the lock hole includes a locking hole and a release hole disposed above the locking hole. The locking hole and the release hole are connected in the vertical direction, and the width of the locking hole is smaller than the head diameter of the locking pin, while the width of the release hole is larger than the head diameter of the locking pin.

[0018] Furthermore, the transmission locking assembly includes a vertically arranged first transmission seat, inside which is a transmission connecting rod indirectly connected to the transmission rod. The pulley assembly includes a horizontally arranged second transmission seat, inside which is a crank connecting rod. The free end of the short shaft of the crank connecting rod is hinged to the transmission connecting rod, and the free end of the long shaft of the crank connecting rod is hinged to a first pulley mounting bracket inside the second transmission seat. The corner where the short shaft and long shaft of the crank connecting rod intersect is rotatably connected to the second transmission seat. The pulley assembly includes a first connecting rod, which is mounted on the first pulley mounting bracket. Inside the frame, a through hole is provided on the top surface of the first pulley mounting bracket. The end face of the through hole forms a second motion trajectory surface from low to high. One end of the first connecting rod is hinged to the first pulley mounting bracket, and the other end contacts the second motion trajectory surface and can slide along the second motion trajectory surface. At least two first pulleys are also provided at intervals inside the first pulley mounting bracket. The first pulleys contact the track on the frame profile and can slide back and forth along the track. When the transmission locking assembly is in the locked state, the crank connecting rod and the first connecting rod are inclined in the same direction, and the top of the crank connecting rod and the top of the first connecting rod are in contact with the top surface of the second transmission seat.

Detailed Implementation

[0030] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings.

[0031] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] This invention specifically provides an embodiment of a transmission lock box, see [link to embodiment]. Figures 1-3 The system includes a mounting housing 1, inside which is a liftable lifting frame 2. Inside the lifting frame 2 is a drive assembly that moves the lifting frame 2 up and down along its length. The drive assembly transmits power along the length of the lifting frame 2, and a portion of the drive assembly passes through the lifting frame 2 and connects to the mounting housing 1. Specifically, the mounting housing 1 is used to connect to the profile cavity of the fan-shaped profile 3. The mounting housing 1 includes a first mounting housing 101 and a second mounting housing 102, which are joined together to form a mounting housing 1 with an inner cavity that extends along the length of the mounting housing 1. The lifting frame 2 is vertically installed in the inner cavity of the mounting housing 1. During lifting, both ends of the lifting frame 2 can extend from the corresponding ports of the mounting housing 1, and the extended portions are used to connect with the transmission locking assembly to drive the transmission locking assembly up and down. The lifting frame 2 includes a first panel, and two symmetrical second panels are formed by bending the two sides of the first panel in the same direction. The first and second panels enclose an installation space for the drive assembly to be installed.

[0034] In the preferred embodiment, see Figure 2 and 3The drive assembly includes a rotating component that can rotate relative to the lifting frame 2 and the mounting housing 1. The rotating component includes a rotating part 4 and a drive part 5 connected to the rotating part 4. The drive part 5 extends in a direction away from the rotating part 4, and the distance between the two side walls of the drive part 5 is equal to or less than the diameter of the rotating part 4. A first transmission tooth 6 is provided at the end of the drive part 5. The drive assembly also includes a first horizontal moving component 7 that can move horizontally relative to the lifting frame 2. A second transmission tooth 8 is provided on the end face of the first horizontal moving component 7 facing the rotating component, and a first motion trajectory surface 9 is provided on the end face of the first horizontal moving component 7 away from the rotating component. The first motion trajectory surface 9 includes a first horizontal segment, a second horizontal segment, and an inclined segment. The height of the first horizontal segment is higher than the height of the second horizontal segment. The first horizontal segment and the second horizontal segment are connected through the inclined segment. The first transmission tooth 6 and the second transmission tooth 8 mesh with each other. The drive assembly also includes a top shaft 10, which is connected to the lifting frame 2 and located above the first horizontal moving component 7, and contacts the first motion trajectory surface 9 on the first horizontal moving component 7. Because the transmission lock box needs to adapt to the profile cavity of extremely narrow profiles, the rotational torque is very small due to the limited space of the profile cavity. Therefore, in this invention, the first horizontal moving member 7 and the rotating member are arranged vertically in an up-down configuration, and the distance between the two side walls of the driving part 5 of the rotating member is equal to or less than the diameter of the rotating part 4. The first horizontal moving member 7 and the rotating member are driven by meshing teeth so that the transmission direction is along the length direction of the lifting frame 2. At the same time, combined with the cooperation of the top shaft 10 and the first motion trajectory surface 9, the first horizontal moving member 7 slides left and right during the left and right swing of the rotating member, thereby causing the top shaft 10 to rise under the action of the first motion trajectory surface 9 and drive the lifting frame 2 to rise, and then fall back with the lifting frame 2 under its own weight. It can be seen that through the cooperation of the rotating member, the first horizontal moving member 7, the top shaft 10, the first motion trajectory surface 9, and the first transmission teeth 6 and the second transmission teeth 8, the rotational torque can be greatly reduced, which can enable the user to drive the fan profile 3 to rise with very little force, and also make the transmission lock box suitable for the profile cavity of extremely narrow profiles. In addition, a vertical second through hole 11 is provided on the surface of the lifting frame 2 opposite to the rotating part 4 of the rotating component. A protrusion 12 is provided on the side wall of the rotating part 4, and the length of the second through hole 11 is greater than the size of the protrusion 12. The protrusion 12 on the rotating part 4 passes through the second through hole 11 and is rotatably connected to the mounting housing 1. By providing the second through hole 11, the lifting frame 2 is prevented from being obstructed from rising and falling.

[0035] See Figure 2 and 3In a preferred embodiment, the transmission lock box further includes at least two first guide shafts 13 spaced apart in the vertical direction. In this embodiment, two first guide shafts 13 spaced apart in the vertical direction are used. The two ends of the first guide shafts 13 are connected to the mounting housing 1. That is, one end of the first guide shaft 13 extends directly from the opening of the lifting frame 2 and is connected to the mounting housing 1. On the side of the lifting frame 2 facing the other end of the first guide shaft 13, a vertical strip-shaped first through hole 14 is provided opposite to the first guide shaft 13. The length of the first through hole 14 is greater than the distance between the two first guide shafts 13. The other end of the first guide shaft 13 passes through the first through hole 14 and is connected to the mounting housing 1. By providing the first through hole 14, the lifting frame 2 is not hindered from lifting. The first horizontal moving member 7 is sleeved on all the first guide shafts 13 and can slide horizontally back and forth relative to the first guide shafts 13. That is, the first horizontal moving member 7 is provided with a number of through holes that are the same as the number of first guide shafts 13, so that the first guide shafts 13 can pass through, so that the first horizontal moving member 7 is sleeved on the first guide shafts 13.

[0036] See Figure 2 and Figure 3 A first return spring 15 is provided between the first horizontal moving member 7 and the mounting housing 1 in the horizontal moving direction of the first horizontal moving member 7. Specifically, a set of rods is horizontally connected to the mounting housing 1. A groove is provided on the surface of the first horizontal moving member 7 opposite to the rod. The first return spring 15 is sleeved on the rod, and its free end extends into the groove on the first horizontal moving member 7. When the first return spring 15 is in its natural state, the top shaft 10 is located on the second horizontal section of the first motion trajectory surface 9. At this time, the lifting frame 2 is in a falling state, and the fan profile 3 cannot slide. When the handle 16 drives the rotating member to swing through the rotating shaft to drive the first horizontal moving member 7 to compress the first return spring 15 and move horizontally, the first motion trajectory surface 9 causes the top shaft 10 to drive the lifting frame 2 to rise, so that the fan profile 3 can slide relative to the frame profile 17. When the handle 16 is released, under the elastic recovery action of the first return spring 15, the first horizontal moving member 7 is pushed to slide in the opposite direction. At this time, the top shaft 10 is no longer subject to the lifting force of the first motion trajectory surface 9, and under the action of the fan profile 3's own weight, it drives the lifting frame 2 and the top shaft 10 to fall back.

[0037] In the preferred embodiment, see Figure 2-5The lifting frame 2 is also equipped with a child lock safety component. The child lock safety component includes a second horizontally movable component 18 and at least two second guide shafts 19 spaced apart in the vertical direction. In this embodiment, two second guide shafts 19 spaced apart in the vertical direction are used. Both ends of the second guide shafts 19 are connected to the mounting housing 1, meaning one end of each second guide shaft 19 extends directly from the opening of the lifting frame 2 and connects to the mounting housing 1. A vertical fourth through hole 20 is provided on the side of the lifting frame 2 facing the other end of the second guide shaft 19, opposite to the second guide shaft 19. The length of the fourth through hole 20 is greater than the distance between the two second guide shafts 19. The other end of each second guide shaft 19 passes through the fourth through hole 20. The second horizontal moving member 7 is connected to the mounting housing 1 and is provided with a fourth through hole 20 to avoid obstructing the lifting frame 2 from rising and falling. The second horizontal moving member 7 is sleeved on all the second guide shafts 19 and can move horizontally back and forth relative to the second guide shafts 19. That is, the second horizontal moving member 18 is provided with through holes at intervals equal to the number of second guide shafts 19, so that the second guide shafts 19 can pass through, and the second horizontal moving member 18 is sleeved on the second guide shafts 19. A positioning shaft 21 is passed through the second horizontal moving member 18 along its thickness direction. An L-shaped hole 22 is provided on the side wall of the lifting frame 2. The positioning shaft 21 extends out of the second horizontal moving member 18 and into the L-shaped hole 22. The second horizontal moving member 18 is partially passed through the fourth through hole 20 on the lifting frame 2 and then... Extending out of the mounting housing 1, a second return spring 23 is provided between the second horizontal moving member 18 and the mounting housing 1 in the horizontal moving direction of the second horizontal moving member 18. Specifically, a connecting rod is horizontally connected to the mounting housing 1, and a mounting groove is provided on the surface of the second horizontal moving member 18 opposite to the connecting rod. The second return spring 23 is sleeved on the connecting rod, and its free end extends into the mounting groove on the second horizontal moving member 18. When the second return spring 23 is in its natural state, a portion of the second return spring 23 extends out of the mounting groove. When the second horizontal moving member 18 is compressed in the horizontal direction (for example, compressed by the cavity wall of the profile cavity of the frame profile 17), the second return spring 23 is compressed, at which time the positioning shaft 21 is located in the L-shaped hole 22. At the top of the vertical section, when the fan profile 3 is lifted, the lifting frame 2 is lifted so that the positioning shaft 21 moves down relative to the vertical section of the L-shaped hole 22 to the intersection of the vertical and horizontal sections. At the same time, after the fan profile 2 slides, the second horizontal moving part 18 is no longer squeezed by the frame profile 17. At this time, the second return spring 23 elastically returns to move the positioning shaft 21 on it, thereby driving the positioning shaft 21 into the horizontal section of the L-shaped hole 22. When the handle 16 is released, the lifting frame 2 is suspended at the horizontal section of the L-shaped hole 22. Even if the drive component is reset, the lifting frame 2 will not fall back, avoiding accidental contact by children or others, which could cause the heavy fan profile 3 to fall and injure others. At this time, the fan profile 3 is always in a state where it can slide relative to the frame profile 17.A shock-absorbing sleeve 24 is fitted on the part of the second horizontal moving part 18 that extends to the outside of the mounting housing 1 to prevent the fan profile 3 and the frame profile 17 from rigidly colliding when locking the box.

[0038] In the preferred embodiment, see Figure 2-5 A gear 25 is provided below the second horizontal moving member 18. A third through hole 26 is provided in the middle of the gear 25. Multiple spiral grooves 27 are provided at intervals on the inner wall of the third through hole 26. In this embodiment, three spiral grooves 27 are used. The child lock safety component also includes a rotating member. The rotating member includes a rotating part 28 that cooperates with the third through hole 26 and a connecting part 29 connected to the rotating part 28. A pressing part 30 is connected to the connecting part 29. Multiple spiral protrusions 31 are provided at intervals on the side wall of the rotating part 28. The number of spiral protrusions 31 is the same as the number of spiral grooves 27, and the two correspond one-to-one. When the rotating member is installed in the third through hole 26, the spiral protrusions 31 are embedded in the corresponding spiral grooves 27. A third transmission tooth 32 is provided on the side of the second horizontal moving member 18 facing the gear 25. The third transmission tooth 32 meshes with the gear 25. During the reciprocating movement of the second horizontal moving member 18, the third transmission gear 32 meshes with the gear 25, causing the gear 25 to rotate reciprocally. Since the wall of the third through hole 26 on the gear 25 is provided with a spiral groove 27, and the side wall of the rotating part 28 of the rotating member that engages with the third through hole 26 is provided with a spiral protrusion 31, the engagement of the spiral groove 27 and the spiral protrusion 31 allows the connecting part 29 to enter the third through hole 26 of the gear 25 during the forward and reverse rotation of the gear 25 (this state indicates the child lock safety component is closed) or the connecting part 29 to extend outside the third through hole 26 (this state indicates the child lock safety component is open). Figure 6As shown; specifically, when the fan-shaped member 3 is locked onto the frame member 17, the second horizontal moving member 18 abuts against the frame member 17, causing the second return spring 23 to be compressed. This causes the positioning shaft 21 on the second horizontal moving member 18 to retract from the horizontal portion of the L-shaped hole 22 of the lifting frame 2 to the intersection of the horizontal and vertical portions, allowing the lifting frame 2 to be in a state where it can fall back. Simultaneously, the second horizontal moving member 18 drives the gear 25 to rotate clockwise. At this time, the connecting part 29 retracts into the third through hole 26 due to the action of the spiral groove 27 and the spiral protrusion 31, and the child lock safety component is in a closed state. When the drive assembly drives the lifting frame 2 to lift, it causes the L-shaped hole 22 on it to rise, causing the positioning shaft 21 on the second horizontal moving member 18 to move downwards relative to the vertical portion of the L-shaped hole 22 to the intersection of the vertical and horizontal portions, allowing the lifting frame 2 to be in a state where it can be suspended, preventing... If the fan-shaped profile 3 falls back and injures a child or user, after the drive component drives the fan-shaped profile 3 to be lifted, when the fan-shaped profile 3 opens relative to the frame profile 17 and can slide relative to the frame profile 17, the second horizontal moving part 18 disengages from the frame profile. At this time, the second horizontal moving part 18 is pushed out under the elastic recovery action of the second return spring 23, and drives the positioning shaft 21 on it to move horizontally from the intersection of the vertical part and the horizontal part of the L-shaped hole 22 on the lifting frame 2 to the horizontal part of the L-shaped hole 22, so that the lifting frame 2 and the fan-shaped profile 3 are in a suspended state. During the process of the second horizontal moving part 18 being pushed out, the third transmission gear 32 on it drives the gear 25 to rotate counterclockwise. At this time, the connecting part 29 is disengaged from the third through hole 26 due to the action of the spiral groove 27 and the spiral protrusion 31. The child lock safety component is in an open state, and the fan-shaped profile 3 can slide freely back and forth relative to the frame profile 17, while also effectively preventing the fan-shaped profile 3 from falling back.When the fan-shaped profile 3 needs to be moved to a certain position on the frame profile 17 and fixed there, the user can press the pressing part 30 of the child lock safety component. The pressing part 30 pushes the connecting part 29 toward the third through hole 26. At the same time, through the cooperation of the spiral groove 27 and the spiral protrusion 31, the gear 25 is rotated clockwise, thereby causing the gear 25 to drive the second horizontal moving part 18 to retract. As the second horizontal moving part 18 retracts, it squeezes the second return spring 23. When the second horizontal moving part 18 drives the positioning shaft 21 on it to completely retract from the horizontal part of the L-shaped hole 22 on the lifting frame 2 to the intersection of the horizontal and vertical parts, the fan-shaped profile 3 is under its own weight. The fan-shaped member 3 falls back, causing the lifting frame 2 to fall back as well. This causes the positioning shaft 21 on the second horizontal moving member 18 to move upward and enter the vertical part of the L-shaped hole 22 on the lifting frame 2. The vertical part of the L-shaped hole 22 limits the positioning shaft 21, preventing the second return spring 23 from elastically returning, and thus preventing the second horizontal moving member 18 from extending. This keeps the child lock safety component in the closed state. The fan-shaped member 3 rests entirely on the guide rail of the frame member 17 due to its own weight. Because of the large weight of the fan-shaped member 3, the contact friction between the fan-shaped member 3 and the frame member 17 is large, effectively preventing the fan-shaped member 3 from moving and keeping it fixed at a certain position on the frame member 17. It should be noted that the directional terms such as "counterclockwise rotation" and "clockwise rotation" of the gear 25 mentioned above are based on... Figure 2-6 The direction of the diagram is determined by the direction of the diagram. When the direction of the diagram changes, the effect of rotating gear 25 in different directions will be reversed.

[0039] The present invention also specifically provides an embodiment of a lift-type sliding door and window. Figure 7-8 The system includes a frame profile 17 and a fan profile 3 that can reciprocate on the frame profile 17. A transmission lock box is installed in the profile cavity on the side of the fan profile 3. The mounting housing 1 of the transmission lock box is connected to the profile cavity wall of the fan profile 3. The lifting frame 2 of the transmission lock box is sequentially connected to a transmission locking assembly and a pulley assembly. The transmission locking assembly is configured for transmission and connection or separation from the frame profile 17, thereby driving the pulley assembly to move and locking or allowing the fan profile 3 to slide. The pulley assembly is configured to slide along the frame profile 17 and lift or lower the fan profile 3. In this embodiment, both the fan profile 3 and the frame profile 17 are extremely narrow profiles.

[0040] See Figure 7-11In a preferred embodiment, the transmission locking assembly includes a transmission rod 33 and a locking assembly. The transmission rod 33 can be a single rod or formed by splicing multiple rods; in this embodiment, two rods are used. One end of the transmission rod 33 is connected to the lifting frame 2 in the transmission lock box, and the other end is indirectly connected to the pulley assembly. Specifically, the rod connected to the transmission lock box is connected to the first connecting seat 34 via a threaded connection, and is connected to the lifting frame 2 of the transmission lock box via the first connecting seat 34. The rod connected to the pulley assembly is connected to the second connecting seat 35 via a threaded connection, and is indirectly connected to the pulley assembly via the second connecting seat 35. Multiple locking assemblies can be used; in this embodiment, two locking assemblies are used. One locking assembly connects the two rods into one unit, and the other locking assembly connects the second connecting seat 35 to the pulley assembly. The locking assembly includes a locking pin mounting seat 36. The locking pin insertion seat 37 is provided. The locking pin mounting seat 36 is installed in the profile cavity of the fan profile 3 and sleeved on the transmission rod 33. The locking pin insertion seat 37 is connected in the profile cavity of the frame profile 17 and is arranged opposite to the locking pin mounting seat 36. Specifically, in this embodiment, the locking assembly for connecting the two rods has a locking pin mounting seat 36 that is threadedly connected to both rods. The locking assembly for connecting the second connecting seat 35 and the pulley assembly has a locking pin mounting seat 36 with one end connected to the second connecting seat 35 and the other end connected to a transmission connecting rod 38. The transmission connecting rod 38 is connected to the pulley assembly. A locking pin 39 is provided on the locking pin mounting seat 36. A locking hole for the locking pin 39 to be inserted is provided on the locking pin insertion seat 37. In the locked state, the locking pin 39 is inserted into the locking hole and is restricted by the locking hole and cannot be removed from the locking hole. In the open state, the locking pin 39 is not restricted by the locking hole and can be removed from the locking hole. In addition, multiple reinforcing support seats 40 are spaced apart on the rod to improve its strength.

[0041] See Figure 11 In a preferred embodiment, the lock hole includes a locking hole 41 and a release hole 42 disposed above the locking hole 41. The locking hole 41 and the release hole 42 are connected in the vertical direction. The width of the locking hole 41 is smaller than the head diameter of the locking pin 39, while the width of the release hole 42 is larger than the head diameter of the locking pin 39. When the locking pin 39 is located in the locking hole 41, because the width of the locking hole 41 is smaller than the head diameter of the locking pin 39, the locking pin 39 is prevented from disengaging. In this state, the fan profile 3 is locked onto the frame profile 17 and cannot slide. When the locking pin 39 is located in the release hole 42, because the width of the release hole 42 is larger than the head diameter of the locking pin 39, the locking pin 39 can disengage from the lock hole. In this state, the fan profile 3 is in a sliding state. The lifting frame 2 drives the transmission rod 33 to rise and fall, thereby driving the locking pin 39 to rise and fall, so that the locking pin 39 is located in the release hole 42 or the locking hole 41.

[0042] In the preferred embodiment, see Figure 10-11The transmission locking assembly includes a vertically arranged first transmission seat 43, inside which is a transmission connecting rod 38 indirectly connected to the transmission rod 33. The pulley assembly includes a horizontally arranged second transmission seat 44, inside which is a crank connecting rod 45. The free end of the short shaft of the crank connecting rod 45 is hinged to the transmission connecting rod 38, and the free end of the long shaft of the crank connecting rod 45 is hinged to a first pulley mounting bracket 46 inside the second transmission seat 44. The corner where the short shaft and long shaft of the crank connecting rod 45 intersect is rotatably connected to the second transmission seat 44. The pulley assembly includes a first connecting rod 47, which is disposed inside the first pulley mounting bracket 46. The top surface of the mounting bracket 46 is provided with a through hole, and the end face of the through hole forms a second motion trajectory surface 48 from low to high. One end of the first connecting rod 47 is hinged to the first pulley mounting bracket 46, and the other end contacts the second motion trajectory surface 48 and can slide along the second motion trajectory surface 48. At least two first pulleys 49 are also provided at intervals in the first pulley mounting bracket 46. In this embodiment, two first pulleys 49 are used. The first pulleys 49 contact the track on the frame profile 17 and can slide back and forth along the track. When the transmission locking assembly is in the locked state, the crank connecting rod 45 and the first connecting rod 47 are inclined in the same direction, and the top of the crank connecting rod 45 and the top of the first connecting rod 47 are in contact with the top surface of the second transmission seat 44. When the lifting frame 2 is raised, it drives the transmission locking assembly to rise. The transmission locking assembly drives the crank connecting rod 45 to swing via the transmission connecting rod 38. The crank connecting rod 45 pulls the first pulley mounting bracket 46 towards the transmission locking assembly, thereby driving the first connecting rod 47 to swing. This causes the crank connecting rod 45 and the first connecting rod 47 to simultaneously push the second transmission seat 44 upward. The second transmission seat 44 then drives the fan-shaped profile 3 to rise, allowing the bottom edge of the fan-shaped profile 3 to slide back and forth after separating from the frame profile 17. The second motion trajectory surface 48 cooperates with the first connecting rod 47 to provide sufficient support force for the first connecting rod 47.

[0043] In the preferred embodiment, see Figure 10-11The sliding assembly further includes a third transmission seat 50, inside which a second pulley mounting bracket 51 is disposed. The second pulley mounting bracket 51 is connected to the first pulley mounting bracket 46 via a linkage rod 52. At least one second pulley 53 is disposed within the second pulley mounting bracket 51. In this embodiment, one second pulley 53 is used. The second pulley 53 contacts the track on the frame profile 17 and can slide back and forth along the track. The pulley assembly includes a second connecting rod 54, which is disposed within the second pulley mounting bracket 51. A track hole is provided on the top surface of 51, and a third motion track surface 55 is formed on the end face of the track hole from low to high. One end of the second connecting rod 54 is hinged to the second pulley mounting bracket 51, and the other end contacts the third motion track surface 55 and can slide along the third motion track surface 55. When the transmission locking assembly is in the locked state, the crank connecting rod 45, the first connecting rod 47, and the second connecting rod 54 are inclined in the same direction, and the top of the crank connecting rod 45 and the top of the first connecting rod 47 are in contact with the top surface of the second transmission seat 44, and the top of the second connecting rod 54 is in contact with the top surface of the third transmission seat 50. When the lifting frame 2 is raised, it drives the transmission locking assembly to rise. The transmission locking assembly drives the crank connecting rod 45 to swing via the transmission connecting rod 38. The crank connecting rod 45 pulls the first pulley mounting bracket 46 and the second pulley mounting bracket 51 to move towards the transmission locking assembly via the linkage rod 52. This causes the first connecting rod 47 and the second connecting rod 54 to swing, thereby causing the crank connecting rod 45 and the first connecting rod 47 to push the second transmission seat 44 upward, and causing the second connecting rod 54 to push the third transmission seat 50 upward. The second transmission seat 44 and the third transmission seat 50 simultaneously drive the fan-shaped profile 3 to rise, making the lifting force more even, so that the bottom edge of the fan-shaped profile 3 can slide back and forth after it is separated from the frame profile 17. The cooperation between the third motion trajectory surface 55 and the second connecting rod 54 provides sufficient support force for the second connecting rod 54.

[0044] In this invention, the fan-shaped member 3 has four states relative to the frame member 17: State 1, when the fan-shaped member 3 is locked onto the frame member 17, the bottom edge of the fan-shaped member 3 is clamped onto the frame member 17. Due to the weight of the fan-shaped member 3 and the locking action of the transmission locking assembly, the fan-shaped member 3 cannot slide. At this time, because the second horizontal moving member 18 abuts against the frame member 17, the second return spring 23 is compressed. The positioning shaft 21 on the second horizontal moving member 18 is located in the vertical part of the L-shaped hole 22 of the lifting frame 2. At this time, the child lock safety component is in the closed state; State 2, when it is necessary to slide the fan-shaped member 3, the drive assembly drives the lifting frame 2 to lift, and drives the L-shaped hole 22 on it to rise, so that the positioning shaft 21 on the second horizontal moving member 18 is relative to the L-shaped hole 22. The vertical part moves down to the intersection of the vertical and horizontal parts, so that the lifting frame 2 is in a suspended state. After the drive assembly drives the fan profile 3 to lift, when the fan profile 3 opens relative to the frame profile 17 and can slide relative to the frame profile 17, the second horizontal moving member 18 disengages from the frame profile 17. At this time, the second horizontal moving member 18 is pushed out under the elastic recovery action of the second return spring 23, and drives the positioning shaft 21 on it to move horizontally from the intersection of the vertical and horizontal parts of the L-shaped hole 22 on the lifting frame 2 to the horizontal part of the L-shaped hole 22, so that the lifting frame 2 and the fan profile 3 are in a suspended state. During the process of the second horizontal moving member 18 being pushed out, the third transmission gear 32 on it drives the gear 25 to rotate counterclockwise. At this time, the connecting part 2 9. Due to the action of the spiral groove 27 and the spiral protrusion 31, the fan-shaped member 3 exits the third through hole 26, and the child lock safety component is in the open state. The fan-shaped member 3 can freely slide back and forth relative to the frame member 17. In the third state, when the fan-shaped member 3 needs to be moved to a certain position on the frame member 17 and fixed, the user can press the pressing part 30 of the child lock safety component. The pressing part 30 pushes the connecting part 29 toward the third through hole 26. At the same time, through the cooperation of the spiral groove 27 and the spiral protrusion 31, the gear 25 is rotated clockwise, so that the gear 25 drives the second horizontal moving part 18 to retract. When the second horizontal moving part 18 retracts, it squeezes the second return spring 23. When the second horizontal moving part 18 drives the positioning shaft 21 on it to exit the water in the L-shaped hole 22 on the lifting frame 2, When the horizontal part is completely withdrawn to the intersection of the horizontal and vertical parts, the fan-shaped member 3 falls back under its own weight, which in turn drives the lifting frame 2 to fall back. This causes the positioning shaft 21 on the second horizontal moving member 18 to move upward and enter the vertical part of the L-shaped hole 22 on the lifting frame 2. The positioning shaft 21 is limited by the vertical part of the L-shaped hole 22, which prevents the second return spring 23 from elastically returning, thereby preventing the second horizontal moving member 18 from extending out, so that the child lock safety component is in the closed state. The entire fan-shaped member 3 is pressed on the guide rail of the frame member 17 by its own weight. Because the fan-shaped member 3 is heavy, the contact friction between the fan-shaped member 3 and the frame member 17 is large, which effectively prevents the fan-shaped member 3 from moving, so that the fan-shaped member 3 is fixed in a certain position on the frame member 17.In state four, when it is necessary for the fan-shaped profile 3 to be locked onto the frame profile 17, the operation in state two is repeated to allow the fan-shaped profile 3 to be in a raised state and able to slide back and forth. After the fan-shaped profile 3 slides until the locking pin 39 of the transmission locking assembly extends into the release hole 42 of the lock hole, the operation in state three is then repeated to allow the fan-shaped profile 3 to fall back, so that the locking pin 39 slides into the locking hole 41 of the lock hole, thereby locking the fan-shaped profile 3 onto the frame profile 17.
