Description

Technical Field

[0001] This utility model belongs to the technical field of door and window hardware accessories, specifically involving buffer structures, locks, and lifting door and window systems. Background Technology

[0002] Currently common lifting door and window systems, taking the novel lifting pulley assembly and lifting door and window system disclosed in Chinese Patent Publication No. CN222558353U as an example, work on the principle of leverage. When the system is running, rotating the handle drives the transmission bar to slide, and the sliding of the transmission bar causes the lifting pulley assembly installed at the bottom of the door leaf to lift or lower, thereby realizing the lifting or lowering action of the door leaf.

[0003] This type of lifting pulley system generally consists of three parts: a transmission assembly, a lifting bracket, and a pulley assembly. The lifting bracket is typically fixed to the door leaf and slidably connected to the pulley assembly via a slanted guide shaft structure. The transmission assembly is responsible for moving the pulley assembly. During operation, the slanted groove and guide shaft slide in coordination. When the lifting bracket and pulley assembly slide relative to each other, their vertical distance changes, thus achieving the lifting and lowering function of the door leaf. However, this existing lifting door and window system has a significant problem: when the door leaf is moved to the lowered position, the lifting bracket or the bottom of the door leaf may collide with the track. This impact not only generates considerable noise, reducing the user experience, but also causes varying degrees of damage to the lifting door and window system. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a buffer structure, a lock and a lifting door and window system, which can not only significantly reduce the noise caused by impact and the damage to the door and window system and track, thereby extending their service life, but also achieve a labor-saving effect in the process of lifting the door and window sash, providing convenience for user operation.

[0005] The technical solution adopted by this utility model to solve its problem is: A buffer structure for a lift-up window / door system, the lift-up window / door system including a door / window sash and a sliding rod connected by a drive mechanism, characterized in that the buffer structure includes: an adjustment assembly including an adjustment rod, a connecting seat, and a mounting seat, the mounting seat being fixed to the door / window sash, the adjustment rod being connected between the mounting seat and the connecting seat, the adjustment rod being used to adjust the position of the connecting seat relative to the mounting seat in a vertical direction; and an elastic element, a first end of the elastic element being connected to the connecting seat, a second end of the elastic element being connected to the sliding rod, the elastic element being configured to apply an elastic force to the sliding rod to provide buffering when the sliding rod drives the door / window sash to move to a lowered position.

[0006] As an optional implementation, the adjusting assembly further includes a worm gear and a worm, the worm being rotatably mounted on the mounting base, the worm and the adjusting rod being coaxial and threaded together, the worm gear and the worm being meshed together, and one end of the adjusting rod being fixedly mounted on the connecting base.

[0007] As an optional implementation, the adjustment assembly further includes an anti-rotation member disposed on the mounting base; the anti-rotation member is movable between a first position and a second position; when in the first position, the anti-rotation member abuts against the side wall of the worm to restrict the rotation of the worm; when in the second position, the anti-rotation member and the worm are separated to release the rotation restriction of the worm.

[0008] As an optional implementation, the second end of the elastic element is provided with a protrusion, which is used to fix it to the sliding rod.

[0009] As an optional implementation, the buffer structure further includes a vertical side frame for fixing to the door / window sash. The vertical side frame is provided with a vertical sliding groove, and the mounting base is fixedly disposed in the vertical sliding groove. A sliding space for the sliding rod to slide is formed between the vertical sliding groove and the mounting base.

[0010] As an optional implementation, the adjustment assembly further includes a first connector. The vertical slide has a bottom wall and side walls connected to both sides of the bottom wall. The bottom wall is used to slide with the sliding rod. The first connector passes through the side wall and the mounting base and is located outside the sliding trajectory of the sliding rod.

[0011] As an optional implementation, the bottom wall of the vertical slide groove is provided with a guide groove extending in the vertical direction, and the guide groove is used to slide in connection with the guide block of the sliding rod.

[0012] In addition, this utility model also provides a lock, including the buffer structure as described in any of the above embodiments, and further including a handle, a lock cylinder and a sliding rod. The lock cylinder is used to be installed on a door or window sash. The handle and the lock cylinder are connected in a driving connection. The lock cylinder and the sliding rod are connected in a driving connection to drive the sliding rod to move up and down.

[0013] As an optional implementation, the lock cylinder has a transmission component that moves up and down under the drive of the handle. The sliding rod is provided with a transmission groove, and the transmission component is engaged in the transmission groove.

[0014] In addition, this utility model also provides a lifting door and window system, including the lock as described in any of the above embodiments, and further including a track, a door / window sash, and a lifting pulley assembly. The lifting pulley assembly includes a lifting bracket, a pulley assembly, and a transmission assembly. The lifting bracket is disposed at the bottom of the door / window sash, the pulley assembly is movably disposed on the lifting bracket, and the transmission assembly is tractively connected between the sliding rod and the pulley assembly. Under the drive of the sliding rod, the pulley assembly moves relative to the lifting bracket between a lowering position and an upward position. When the pulley assembly is in the lowering position, it contacts the track, and the door / window sash is in the lifting position. When the pulley assembly is in the upward position, the bottom of the lifting bracket or the door / window sash abuts against the track, and the door / window sash is in the lowered position.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the elastic element applies an elastic force to the sliding rod. When the sliding rod moves the door and window sash to the lowered position through the lifting pulley group, the elastic element will play a buffering role, thereby effectively preventing the lifting bracket or the bottom of the door and window sash from directly and violently colliding with the track. This buffering mechanism reduces the noise caused by the impact, reduces the damage caused by the impact to the lifting door and window system, and extends the service life of the entire system.

[0016] Secondly, given that the elastic force applied by the elastic element to the sliding rod can provide a buffering force during the sinking of the door and window sash, the elastic force of the elastic element to the sliding rod can assist the sliding rod in moving the door and window sash to the raised position, thus achieving a labor-saving effect. In this way, it is easier, more convenient, and more efficient for users to operate the lifting of the door and window sash.

[0017] Thirdly, the position of the connecting seat relative to the mounting seat can be adjusted in the vertical direction by adjusting the adjusting rod. This adjustment method is intuitive and easy to operate. Users do not need complicated operating procedures. They only need to rotate or move the adjusting rod to accurately change the position of the connecting seat. The change in the position of the connecting seat will directly affect the degree of tension or compression of the elastic element, thereby achieving precise adjustment of the elastic force.

[0026] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0027] Please see Figures 1 to 8This utility model embodiment provides a buffer structure 6 for lifting a door and window system. The lifting door and window system includes a door and window sash 1, a sliding rod 4, and a lifting pulley group 3. The sliding rod 4 slides up and down on the door and window sash 1, and the lifting pulley group 3 is located at the bottom of the door and window sash 1. The sliding rod 4 and the lifting pulley group 3 are connected by a transmission. The sliding rod 4 moves up and down to drive the lifting pulley group 3 to switch between a sliding state and a fixed state.

[0028] When the lifting pulley block 3 is in the sliding state, the pulley assembly 32 of the lifting pulley block 3 is in contact with the track 2, and the door and window sash 1 is in the lifting position. At this time, the door and window sash 1 is in a free state that can slide along the track 2. When the lifting pulley block 3 is in a fixed state, the lifting bracket 31 of the lifting pulley block 3 or the bottom of the door / window sash 1 contacts the track 2, and the door / window sash 1 is in a fixed state that cannot be slid.

[0029] The buffer structure 6 includes an adjusting assembly 60 and an elastic element 69. The adjusting assembly 60 includes an adjusting rod 61, a connecting seat 62, and a mounting seat 63. The mounting seat 63 is used to fix the door / window sash 1. The adjusting rod 61 is connected between the mounting seat 63 and the connecting seat 62. The adjusting rod 61 is used to adjust the position of the connecting seat 62 relative to the mounting seat 63 in the vertical direction. The first end of the elastic element 69 is connected to the connecting seat 62, and the second end of the elastic element 69 is used to connect to the sliding rod 4. The elastic element 69 is configured to apply an elastic force to the sliding rod 4 to provide buffering when the sliding rod 4 drives the door / window sash 1 to move to the sunken position.

[0030] The buffer structure 6 provided in this embodiment of the utility model firstly involves the elastic element 69 applying an elastic force to the sliding rod 4. When the sliding rod 4 moves the door / window sash 1 to the lowered position via the lifting pulley group 3, the elastic element 69 provides buffering performance, effectively preventing direct and violent collisions between the lifting bracket 31 or the bottom of the door / window sash 1 and the track 2. This buffering mechanism reduces noise caused by impacts, minimizes damage to the lifting door / window system, and extends the service life of the entire system. Secondly, since the elastic force applied by the elastic element 69 to the sliding rod 4 provides buffering force during the lowering of the door / window sash 1, the elastic force of the elastic element 69 on the sliding rod 4 can assist the sliding rod 4 in moving the door / window sash 1 to the lifting position, achieving a labor-saving effect. In this way, it is easier, more convenient, and more efficient for users to operate the lifting of the door / window sash 1.

[0031] Finally, the position of the connecting seat 62 relative to the mounting seat 63 is adjusted vertically using the adjusting rod 61. This adjustment method is intuitive and easy to operate. Users do not need complicated operating procedures; they only need to rotate or move the adjusting rod 61 to accurately change the position of the connecting seat 62. The change in the position of the connecting seat 62 directly affects the degree of tension or compression of the elastic element 69, thereby achieving precise adjustment of the elastic force. Furthermore, when the adjusting rod 61 adjusts the position of the connecting seat 62 vertically, the movement trajectory of the connecting seat 62 is clear and smooth. It moves along the axis of the adjusting rod 61 without any deviation or jamming. This allows the elastic element 69 to maintain a uniform and stable state during tension or compression. This stable movement process not only facilitates precise control of the elastic force but also effectively avoids damage to the elastic element 69 caused by unstable adjustment, thereby extending the service life of the elastic element 69 and the entire adjusting assembly 60. In addition, the mounting base 63 is firmly fixed to the door and window sash 1, providing a stable support base for the entire adjustment assembly 60. This stable installation method ensures that the adjustment rod 61 and the connecting seat 62 will not shake or shift during operation. Even if the door and window sash 1 is in a dynamic environment of frequent opening and closing, the mounting base 63 can always remain in the same position, providing a reliable reference for the adjustment assembly 60. In this way, the accuracy and stability of the elastic force adjustment are guaranteed, enabling the entire lifting door and window system to operate stably.

[0032] Understandably, in actual use cases, the materials of track 2 differ, the weights of door and window sashes 1 vary, and the sinking speeds of door and window sashes 1 also differ. These factors all lead to diverse requirements for the cushioning effect. By flexibly adjusting the elastic force of elastic element 69 using adjustment component 60, the strength and degree of cushioning can be precisely controlled according to specific door and window system parameters and actual usage conditions, thereby meeting the cushioning needs under different circumstances. Furthermore, as time goes by, the elastic element 69 will inevitably experience elastic decay, which will cause a change in the elastic force it applies to the sliding rod 4. Without the adjustment component 60, the system's buffering and auxiliary operation functions will be negatively affected after the elastic element 69's elasticity decays, thus accelerating the damage to components such as the door and window sash 1 and the track 2. The existence of the adjustment component 60 allows for timely adjustment of the elastic force of the elastic element 69, compensating for the reduced force due to elastic decay, and keeping the system in good working condition. In this way, not only can the system's buffering and shock absorption functions and labor-saving operation functions be ensured to function normally, but the service life of the entire lifting door and window system and the track 2 can also be effectively extended, reducing subsequent maintenance and replacement costs.

[0033] like Figure 11 and Figure 12As shown, in one embodiment, the lifting bracket 31 and the pulley assembly 32 achieve relative movement through a sliding fit of an inclined groove and a guide shaft. It is understood that the lifting pulley assembly 3 described in this embodiment is a pulley mechanism well-known to those skilled in the art, and its specific structure can be found in Chinese Patent Publication No. CNCN222558353U. Of course, the lifting pulley assembly 3 can also be other pulley mechanisms capable of achieving the same function, which will not be elaborated upon here.

[0034] like Figure 11 and Figure 12 As shown, for example, in one embodiment, the lifting pulley block 3 includes a lifting bracket 31, a pulley assembly 32, and a transmission assembly 33. The lifting bracket 31 is located at the bottom of the door / window sash 1, the pulley assembly 32 is movably mounted on the lifting bracket 31, and the transmission assembly 33 is drively connected between the sliding rod 4 and the pulley assembly 32. The transmission assembly 33 is used to transmit power to drive the pulley assembly 32 to move relative to the lifting bracket 31 between a rising position and a falling position. When the sliding rod 4 moves downward, under the drive of the transmission assembly 33, the pulley assembly 32 moves relative to the lifting bracket. When the sliding rod 31 moves upward to the raised position, the pulley assembly 32 separates from the track 2, and simultaneously the bottom of the lifting bracket 31 or the door / window sash 1 contacts the track 2. The door / window sash 1 is in the lowered position, and the lifting pulley assembly 3 is in a fixed state, at which time the door / window sash 1 cannot slide. When the sliding rod 4 moves upward, driven by the transmission assembly 33, the pulley assembly 32 moves downward relative to the lifting bracket 31 to the lowered position, the pulley assembly 32 contacts the track 2, the door / window sash 1 is in the raised position, and the lifting pulley assembly 3 is in a sliding state, at which time the door / window sash 1 can slide along the track 2. In this embodiment, the elastic element 69 needs to be configured to apply an upward elastic force to the sliding rod 4.

[0035] For example, in one embodiment, the lifting pulley block 3 includes a lifting bracket 31, a pulley assembly 32, and a transmission assembly 33. The lifting bracket 31 is located at the bottom of the door / window sash 1, the pulley assembly 32 is movably mounted on the lifting bracket 31, and the transmission assembly 33 is drively connected between the sliding rod 4 and the pulley assembly 32. The transmission assembly 33 is used to transmit power to drive the pulley assembly 32 to move relative to the lifting bracket 31 between a rising position and a falling position. When the sliding rod 4 moves upward, under the drive of the transmission assembly 33, the pulley assembly 32 moves upward relative to the lifting bracket 31 to the rising position. When the sliding rod 4 separates from the track 2, the bottom of the lifting bracket 31 or the door / window sash 1 contacts the track 2, the door / window sash 1 is in the sunken position, and the lifting pulley group 3 is in the fixed state. At this time, the door / window sash 1 cannot slide. When the sliding rod 4 moves downward, under the drive of the transmission component 33, the pulley assembly 32 moves downward relative to the lifting bracket 31 to the lowered position. The pulley assembly 32 contacts the track 2, the door / window sash 1 is in the raised position, and the lifting pulley group 3 is in the sliding state. At this time, the door / window sash 1 can slide along the track 2. In this embodiment, the elastic element 69 needs to be configured to apply a downward elastic force to the sliding rod 4.

[0036] like Figure 1 , Figure 11 and Figure 12 As shown, in one embodiment, the lifting pulley block 3 further includes a connecting rod 34, and two pulley assemblies 32 are respectively connected to the two ends of the connecting rod 34. The two pulley assemblies 32 are respectively located at the bottom ends of the door and window sash 1. The connecting rod 34 can be used to make the two pulley assemblies 32 rise or fall synchronously relative to the lifting bracket 31.

[0037] It is understandable that in some other embodiments, the lifting bracket 31 may also be part of the bottom of the door / window sash 1, and can be designed according to actual needs.

[0038] like Figure 4 and Figure 5As shown, in one embodiment, a protrusion 691 is provided at the second end of the elastic member 69, which is used to fix it to the sliding rod 4. Thus, firstly, the protrusion 691 acts as a key intermediate connecting component between the elastic member 69 and the sliding rod 4. It can transmit the elastic force of the elastic member 69 to the sliding rod 4 with extremely high precision. During the extension and retraction of the elastic member 69, the protrusion 691 can ensure that the direction of the force is always highly consistent with the direction of movement of the sliding rod 4. This effectively reduces force loss and directional deviation, allowing the sliding rod 4 to accurately drive the door / window sash 1 to move in a pre-set manner, greatly improving the accuracy of operation. Secondly, the protrusion 691 significantly enhances the connection strength and stability between the sliding rod 4 and the elastic element 69. Compared with directly connecting the elastic element 69 to the sliding rod 4, the protrusion 691 has the function of dispersing the force applied by the elastic element 69. It can prevent the sliding rod 4 from deforming or being damaged due to excessive force, thereby ensuring the reliability of the connection between the sliding rod 4 and the elastic element 69 and extending the service life of related components.

[0039] like Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the elastic element 69 is a tension spring. Thus, the tension spring has the characteristic that the tension changes stably with the amount of elongation within its elastic limit. In the lifting door and window system, when the door or window is opened or closed, the sliding rod 4 drives the protrusion 691 to move, thereby extending or shortening the tension spring. The tension spring can provide a corresponding and stable tension according to its elongation, continuously and uniformly applying an upward elastic force to the sliding rod 4 through the protrusion 691.

[0040] It should be noted that in some other embodiments, the elastic element 69 may also be, but is not limited to, elastic rubber, elastic silicone or other types of springs, as long as it can apply an upward elastic force to the sliding rod 4, and is not limited to one type.

[0041] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the buffer structure 6 further includes a vertical side frame 12, which is fixed to the side edge of the door / window sash 1. The vertical side frame 12 is provided with a vertical sliding groove 13, and the mounting base 63 is fixedly disposed in the vertical sliding groove 13. A sliding space for the sliding rod 4 to slide is formed between the mounting base 63 and the vertical sliding groove 13. Thus, firstly, by setting the vertical sliding groove 13 on the vertical side frame 12, the longitudinal space of the door / window sash 1 frame is cleverly utilized. This design does not occupy excessive space inside or outside the door / window sash 1, making the structure of the entire lifting door / window system more concise and compact. Under limited space conditions, the installation and sliding function of the sliding rod 4 can still be smoothly realized, greatly improving the space utilization efficiency. This design has significant advantages, especially for building door / window designs with extremely strict space requirements. Secondly, the vertical slide 13 provides a clear and defined movement track 2 for the sliding rod 4. At the same time, the mounting base 63 is fixed in the vertical slide 13, so that the sliding rod 4, the adjusting component 60, the elastic element 69 and other components can be integrated in an orderly manner with the vertical slide 13 as the center. This integrated design concept is extremely beneficial to the modular production and installation of the entire lifting door and window system. The relative positional relationship between the various components becomes clearer and more defined, which greatly reduces the possible errors during installation, reduces the difficulty of debugging, and thus improves production efficiency and installation quality.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the adjusting assembly 60 further includes a first connecting member 66. The vertical slide groove 13 has a bottom wall 131 and side walls 132 connected to both sides of the bottom wall 131. Both the bottom wall 131 and the side walls 132 are vertically arranged. The sliding rod 4 is slidably connected to the bottom wall 131. The first connecting member 66 passes through the side wall 132 and the mounting base 63. The first connecting member 66 is located outside the sliding trajectory of the sliding rod 4. In this way, the first connecting member 66 can effectively avoid interfering with the sliding process of the sliding rod 4. As a result, the sliding rod 4 can move stably along the preset trajectory without any obstruction, which greatly improves the efficiency and accuracy of the transmission. At the same time, due to the reduction of motion interference, the noise generated by the friction between the components is also reduced, and the wear rate of the components is slowed down, thus extending the service life of the entire lifting door and window system.

[0043] like Figure 1 , Figure 9 and Figure 10 As shown, in one embodiment, the buffer structure 6 further includes a second connector 7, and the door / window sash 1 has a sash body 11. The second connector 7 passes through the vertical side frame 12 and the sash body 11 to fix the vertical side frame 12 to the sash body 11.

[0044] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the vertical side frame 12 is provided with a first connecting hole 121 and a second connecting hole 122, a first connector 66 passes through the first connecting hole 121 and the mounting base 63, and a second connector 7 passes through the second connector 7 and the fan body.

[0045] like Figure 4 , Figure 5 and Figure 10 As shown, in one embodiment, the sliding rod 4 is provided with a guide block 41, and the bottom wall 131 of the vertical slide groove 13 is provided with a guide groove 133 extending in the vertical direction. The guide block 41 and the guide groove 133 are slidably connected. Thus, the slidable connection between the guide block 41 and the guide groove 133 provides precise linear motion guidance for the sliding rod 4. During the lifting or lowering of the door / window sash 1, the sliding rod 4 needs to make precise linear movements in the vertical direction to ensure that the door / window sash 1 can open and close smoothly and accurately. The guide groove 133 extends in the vertical direction, and the guide block 41 slides within the guide groove 133, so that the sliding rod 4 can only move along the path specified by the guide groove 133, effectively preventing lateral deviation or wobbling of the sliding rod 4 during movement, thereby ensuring the accuracy and stability of the transmission.

[0046] like Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, in one embodiment, the adjusting assembly 60 further includes a worm gear 64 and a worm 65. The worm 65 is rotatably mounted on the mounting base 63. The worm 65 and the adjusting rod 61 are coaxial and threaded together. The worm gear 64 and the worm 65 are meshed together. One end of the adjusting rod 61 is fixedly mounted on the connecting base 62. When the worm gear 64 rotates, it can drive the worm 65 to rotate. Under the drive of the worm 65, the adjusting rod 61 moves up and down to drive the connecting base 62 to move up and down relative to the mounting base 63. Thus, firstly, the structural design of the worm gear 64 and worm 65 transmission gives the operator the advantage of effortless adjustment. The operator only needs to apply a small force to rotate the worm gear 64 to drive the adjusting rod 61. Moreover, by rationally designing the various parameters of the worm gear 64 and worm 65, this effort-saving effect can be further amplified, making the adjustment operation easy to complete. In addition, when it is necessary to precisely set the opening force of the door and window sash 1, the operator can slowly rotate the worm gear 64 to achieve precise control of the extremely small displacement of the adjusting rod 61, thereby finely adjusting the elastic force of the elastic element 69 to the ideal state, fully meeting the personalized needs of different users for the operating feel. Secondly, the meshing transmission process between the worm gear 64 and the worm 65 is extremely smooth, with no obvious impact or vibration. During the adjustment process, the rotation of the worm gear 64 is transmitted evenly and continuously to the worm 65, which then drives the adjusting rod 61 to move up and down smoothly. This smooth transmission method effectively avoids adjustment errors caused by sudden force transmission, ensuring the accuracy and stability of the movement of the connecting seat 62, and providing a strong guarantee for improving the stable operation of the door and window system. Thirdly, the worm gear 64 and worm 65 transmission mechanism can be designed to be relatively compact, with the worm 65 rotatably mounted inside the mounting base 63, the worm gear 64 meshing with the worm 65, and the adjusting rod 61 coaxially arranged with the worm 65. This layout makes full use of the space inside the mounting base 63 without occupying too much external space of the door and window sash 1. In the overall design of the lifting door and window system, this compact structure helps to reduce the size and weight of the system, making the door and window sash 1 lighter and more aesthetically pleasing. At the same time, it also provides more space for the installation and layout of other components, facilitating the integrated design of the system and improving the performance and quality of the entire lifting door and window system.

[0047] It should be noted that in some other embodiments, the adjusting component 60 may also be, but is not limited to, a telescopic rod mechanism, a gear and rack mechanism, or a cam and slider mechanism, as long as it can adjust the installation position of the first end of the elastic member 69 relative to the door and window sash 1 to adjust the elastic force applied upward by the elastic member 69 to the sliding rod 4. There is no single limitation here.

[0048] like Figure 7 and Figure 8As shown, in one embodiment, the adjusting assembly 60 further includes an anti-rotation member 67, which is disposed on the mounting base 63. The anti-rotation member 67 can move between a first position and a second position. In the first position, the anti-rotation member 67 abuts against the side wall of the worm gear 65 to restrict the rotation of the worm gear 65. In the second position, the anti-rotation member 67 separates from the worm gear 65 to release the rotation restriction of the worm gear 65. Thus, firstly, in the daily use or transportation of the lifting door and window system, it is inevitable to be affected by unexpected factors such as external vibration and collisions, which may cause the worm gear 65 to rotate unexpectedly. When the anti-rotation member 67 is in the first position, it acts like a loyal guardian, firmly abutting against the side wall of the worm gear 65 and effectively preventing the rotation of the worm gear 65. This feature can prevent the adjusting rod 61 from moving due to the unexpected rotation of the worm gear 65, thereby preventing the position of the connecting base 62 from changing, ensuring that the operating force of the door and window sash 1 will not change abnormally, and providing a solid guarantee for the stable operation of the system under various complex conditions. Secondly, the anti-rotation component 67 can move freely between the first and second positions, providing operators with an extremely flexible operating method. During adjustment, the operator only needs to easily move the anti-rotation component 67 to the second position, separating it from the worm 65 and releasing the restriction on the rotation of the worm 65. At this time, the operator can freely rotate the worm wheel 64, which drives the worm 65 and the adjusting rod 61 to move, thereby achieving precise adjustment of the position of the connecting seat 62. After the adjustment is completed, the anti-rotation component 67 is moved back to the first position to re-restrict the rotation of the worm 65 and firmly lock the adjustment result. This flexible switching method makes the adjustment process more convenient and efficient. Operators can adjust and lock the operation at any time according to actual needs, greatly improving the convenience and practicality of use.

[0049] like Figure 9 and Figure 10 As shown, in one embodiment, the door / window sash 1 is provided with a perforated groove 14, which exposes the worm gear 64 and the anti-rotation component 67 for easy operation. Thus, the perforated groove 14 directly exposes the worm gear 64 and the anti-rotation component 67 within the operator's line of sight, allowing the operator to quickly and accurately locate the components to be operated without having to search for them. For example, when adjusting the operating force of the door / window sash 1, the operator can see the position of the worm gear 64 at a glance and directly reach out to rotate it; when locking or unlocking the rotation of the worm 65, the operator can also quickly locate the anti-rotation component 67 and move it. This intuitive operation method greatly saves operating time and improves operating efficiency.

[0050] As shown in Figures 7 and 8, and Figure 10As shown, in one embodiment, a first operating part 641 is provided on the side of the worm gear 64 near the hollowed-out groove 14. The first operating part 641 is used by an operator to rotate the worm gear 64.

[0051] like Figure 7 , Figure 8 and Figure 10 As shown, in one embodiment, the anti-rotation member 67 is screwed to the mounting base 63, and a second operating part 671 is provided on the side of the anti-rotation member 67 near the hollow groove 14. The second operating part 671 is used for the operator to operate to turn the anti-rotation member 67.

[0052] like Figure 1 , Figure 9 and Figure 10 As shown, in one embodiment, the cutout groove 14 is located on the vertical side frame 12.

[0053] like Figure 3 , Figure 7 and Figure 8 As shown, in one embodiment, the adjusting assembly 60 further includes a limiting ring 68, which is sleeved on the adjusting rod 61. When the adjusting rod 61 moves to its lowest position relative to the worm gear 65, the limiting ring 68 and the worm gear 65 abut against each other to limit the downward movement of the adjusting rod 61. Thus, firstly, during the use of the lifting door and window system, it is necessary to precisely control the elastic force applied by the elastic element 69 to the sliding rod 4 to meet different usage requirements. If the movement of the adjusting rod 61 is unrestricted, over-adjustment or under-adjustment may occur, resulting in the elastic force failing to accurately reach the set value. The limiting ring 68, by limiting the downward movement of the adjusting rod 61, ensures that each adjustment is within a certain range, helping the user to adjust the elastic force more accurately, ensuring that the elastic force is always maintained at a suitable level, and improving the accuracy of the adjustment. Secondly, for the elastic element 69, excessive deformation may cause it to exceed its elastic limit, resulting in permanent damage and making it impossible to restore its original elastic properties, thereby affecting the normal operation of the entire lifting door and window system; the limiting ring 68 abuts against the worm gear 65 when the adjusting rod 61 moves to the lowest position, effectively limiting the downward movement of the adjusting rod 61, preventing the elastic element 69 from being damaged due to excessive deformation, extending the service life of the elastic element 69, and reducing maintenance and replacement costs.

[0054] It should be noted that in some other embodiments, the limiting ring 68 can also be used to limit the upward movement of the adjusting rod 61. When the adjusting rod 61 moves to the highest position relative to the worm gear 65, the limiting ring 68 can be made to abut against the adjusting rod 61.

[0055] like Figure 3 , Figure 7 and Figure 8As shown, in one embodiment, the worm gear 65 is fitted onto the adjusting rod 61. This design, where the worm gear 65 is fitted onto the adjusting rod 61, integrates the two key components into a single spatial arrangement. In the limited internal space of the lifting window system, this design avoids the need for an additional installation location for the worm gear 65, reducing space occupation. Furthermore, the worm gear 65 is directly fitted onto the adjusting rod 61, achieving direct transmission between the two. Compared to the traditional method of transmission via an intermediate connector, this direct transmission reduces energy loss in the transmission process. During the adjustment of the elastic force, the worm wheel 64 drives the worm gear 65 to rotate. The rotational force of the worm gear 65 can be transmitted to the adjusting rod 61 more directly and efficiently, causing the adjusting rod 61 to move accordingly. This allows for more precise adjustment of the elastic force applied by the elastic element 69 to the sliding rod 4, improving transmission efficiency.

[0056] like Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the mounting base 63 includes a first base 631 and a second base 632 connected to each other. The worm gear 64 is rotatably mounted on the first base 631, and the worm 65 is rotatably mounted on the second base 632. Thus, firstly, the two bases provide independent support for the worm gear 64 and the worm 65 respectively. This independent support method can reduce the vibration interference between the worm gear 64 and the worm 65 during transmission; for example, when the worm gear 64 rotates, the vibration it generates will not be directly transmitted to the support structure of the worm 65, and vice versa, thereby ensuring that the worm gear 64 and the worm 65 can rotate more smoothly and improving the stability of the transmission. Secondly, this split design allows for more flexible arrangement of the positions of the worm gear 64 and the worm 65. Depending on the actual space conditions of the lifting door and window system, the installation positions of the first seat 631 and the second seat 632 can be adjusted separately, so that the worm gear 64 and the worm 65 can achieve the best transmission layout in a limited space. This avoids the space waste or component interference problems that may be caused by the integrated mounting seat 63 design, and improves the utilization rate of the internal space of the system.

[0057] like Figure 8 As shown, in one embodiment, one of the first base 631 and the second base 632 is provided with a locking block 6321, and the other is provided with a locking slot 6311, and the locking block 6321 and the locking slot 6311 are engaged.

[0058] like Figure 8 As shown, in one embodiment, at least two first connectors 66 are provided, and the at least two first connectors 66 are respectively passed through the first base 631 and the second base 632.

[0059] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in one embodiment, the axis of the worm gear 64 is arranged horizontally, and the axis of the worm 65 is arranged vertically, with the axes of the worm gear 64 and the worm 65 perpendicular to each other. Thus, in the lifting door and window system, the horizontal and vertical directions are the two main spatial dimensions. The layout of the worm gear 64 being horizontally arranged and the worm 65 being vertically arranged with perpendicular axes can make full use of the limited vertical space inside the door and window system. In relatively narrow vertical areas such as the sides or top of the door and window sash 1, the worm gear 64 and the worm 65 can be rationally arranged, avoiding occupying too much space in a single horizontal or vertical direction, making the entire adjusting assembly 60 more compact and adaptable to the confined installation environment of the door and window system.

[0060] like Figure 1 , Figure 4 and Figure 6 As shown, in addition, this utility model embodiment also provides a lock, including the buffer structure 6 as described in any of the above embodiments, and also includes a handle 8 and a lock cylinder 5. The handle 8 and the lock cylinder 5 are connected in a transmission manner, and the lock cylinder 5 and the sliding rod 4 are connected in a transmission manner to drive the sliding rod 4 to move up and down.

[0061] like Figure 6 As shown, in one embodiment, the lock cylinder 5 has a transmission member 51, and the sliding rod 4 has a transmission groove 42. The transmission member 51 and the transmission groove 42 are engaged. The operating handle 8 can drive the transmission member 51 to move up and down, so that the sliding rod 4 can be driven to move up and down synchronously with the transmission member 51 through the engagement between the transmission member 51 and the transmission groove 42.

[0062] like Figures 1 to 12 As shown, this utility model embodiment also provides a lifting door and window system, including the lock as described in any of the above embodiments, and also includes a track 2, a door / window sash 1, and a lifting pulley assembly 3. The lifting pulley assembly 3 includes a lifting bracket 31, a pulley assembly 32, and a transmission assembly 33. The lifting bracket 31 is located at the bottom of the door / window sash 1, the pulley assembly 32 is movably mounted on the lifting bracket 31, and the transmission assembly 33 is tractively connected between the sliding rod 4 and the pulley assembly 32. Under the drive of the sliding rod 4, the pulley assembly 32 moves relative to the lifting bracket 31 between a lowering position and an upward position. When the pulley assembly 32 is in the lowering position, it contacts the track 2, the lifting pulley assembly 3 is in a sliding state, and the door / window sash 1 is in a raised position. When the pulley assembly 32 is in the upward position, the bottom of the lifting bracket 31 or the door / window sash 1 abuts against the track 2, the lifting pulley assembly 3 is in a fixed state, and the door / window sash 1 is in a lowered position.

[0063] In summary, the buffer structure 6, lock, and lifting door and window system disclosed in this utility model can bring at least the following beneficial technical effects: (1) When the sliding rod 4 moves the door and window sash 1 to the sunken position through the lifting pulley group 3, the elastic element 69 will play a buffering role, thereby effectively preventing the lifting bracket 31 or the bottom of the door and window sash 1 from having a direct and violent collision with the track 2.

[0064] (2) The elastic force of the elastic element 69 on the sliding rod 4 can assist the sliding rod 4 in moving the door and window sash 1 to the lifting position, thus achieving the effect of saving effort. In this way, the user can operate the lifting of the door and window sash 1 more easily, effortlessly, conveniently and efficiently.

[0065] (3) By flexibly adjusting the elastic force of the elastic element 69 with the help of the adjusting component 60, the strength and degree of buffering can be precisely controlled according to the specific door and window system parameters and actual usage conditions, thereby meeting the buffering needs under different circumstances. (4) The existence of the adjustment component 60 allows the elastic force of the elastic element 69 to be adjusted in a timely manner to compensate for the reduced force due to elastic decay, so that the system can always maintain a good working state. This not only ensures that the system's buffering and shock absorption function and labor-saving operation function can function normally, but also effectively extends the service life of the entire lifting door and window system and track 2.

[0066] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
