Description

Technical Field

[0001] This invention relates to the field of building door and window technology, and in particular to a lift-up sliding door and window. Background Technology

[0002] Sliding doors and windows have the advantages of not taking up indoor space, beautiful appearance, economical price, and good airtightness. With the improvement of people's quality of life and changes in aesthetic style, people have begun to pursue the maximization of visual space, and the types of sliding doors and windows have gradually become more diversified. Lifting sliding doors and windows are one of the many types of sliding doors and windows.

[0003] To ensure better sealing and safety performance than ordinary sliding doors and windows, the dimensions and weight of the doors or windows are usually designed to be very large. This design means that even a slight change in the shape and size of the bottom rollers of the sliding door or window will result in a large dimensional change on the side of the sliding door or window. In actual production, there are unavoidable dimensional errors in the tracks of sliding doors and windows and limit sliding doors and windows, which leads to a decrease in the sealing performance of the sliding doors and windows, or even failure to lock, affecting safety performance and greatly reducing the user experience. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a lift-up sliding door and window that can be adjusted according to the actual installation dimensions.

[0005] The technical solution adopted by this invention to solve its problem is:

[0006] A lift-up sliding door / window, comprising:

[0007] Main body of doors and windows;

[0008] A pulley mechanism is provided on the bottom surface of the main body of the door and window, and the pulley mechanism is used to support and move the main body of the door and window;

[0009] The pulley mechanism includes a first end pulley group and a middle pulley group. The first end pulley group has a degree of freedom in the vertical direction and can adjust the end height of the door and window body.

[0010] The intermediate pulley block is equipped with an elastic element;

[0011] When the height of the end of the door / window body changes, the elastic element is used to adjust the height of the intermediate pulley group to keep the bottom surface of the door / window body level.

[0012] With this setup, in practical applications, the first end pulley group and the middle pulley group can adjust the height and level of the door and window body, ensuring that the door and window body fits tightly with the casing structure in both the horizontal and vertical directions, guaranteeing good airtightness. At the same time, it also ensures that the lock box on the door and window body can lock and unlock normally, providing users with a good user experience.

[0013] According to a preferred embodiment, the first end pulley assembly includes a first cover plate and pulleys, at least one of the pulleys being configured as a movable wheel;

[0014] The first cover plate has a first movable shaft hole, and the axis of the movable wheel is movably disposed in the first movable shaft hole to adjust the height of the movable wheel.

[0015] With this design, the height of the movable wheels at the ends changes, thus changing the height of the end of the door and window body. The levelness of the door and window body also changes accordingly, ensuring a tight fit with the casing structure in both the horizontal and vertical directions, guaranteeing good airtightness.

[0016] According to a preferred embodiment, the first end pulley group further includes an adjustment component, wherein a movable shaft passes through the axle of the movable wheel, and the movable shaft passes through the adjustment component, and the adjustment component is used to adjust the position of the movable shaft in the first movable shaft hole.

[0017] According to a preferred embodiment, the adjustment assembly includes an end seat, the end seat having a second movable shaft hole, the angle between the extension direction of the second movable shaft hole and the horizontal direction being configured to be greater than 0° and less than 90°.

[0018] The movable shaft passes through the first movable shaft hole and the second movable shaft hole.

[0019] With this configuration, the position of the adjustment component can be adjusted horizontally to change the position of the movable shaft in the second movable shaft hole, which in turn changes its position in the first movable shaft hole, thus changing the height of the movable wheel. Compared to adjusting in the vertical direction, horizontal adjustment is more convenient and reduces the difficulty of operation.

[0020] According to a preferred embodiment, the intermediate pulley group includes a second cover plate and a second connecting member. The intermediate pulley group is connected to the first end pulley group through a profile. One end of the second connecting member is used for insertion connection with the profile.

[0021] The second cover plate is provided in pairs at both ends of the second connector.

[0022] According to a preferred embodiment, the intermediate pulley group further includes an elastic element and a pulley assembly, the pulley assembly being clamped and movably connected to the two second cover plates;

[0023] One end of the elastic element is fixedly connected to the second connecting element, and the other end is fixedly connected to the pulley assembly;

[0024] When the first end pulley assembly causes a change in the height of the door and window body, and the pressure of the door and window body on the pulley assembly is greater than the initial tension of the elastic element, the elastic element is compressed, and the pulley assembly rotates relative to the second cover plate to adjust the bottom surface of the door and window body to remain horizontal.

[0025] With this setup, because the main body of the door and window is large, even if the height of the first end pulley group is adjusted by a small range, the overall height and levelness will change significantly. Under the action of the elastic element, the pulley assembly rotates relative to the second cover plate to balance the pressure on the main body of the door and window, so that the bottom surface of the main body of the door and window remains level.

[0026] According to a preferred embodiment, the system further includes a control component and a handle, wherein the handle drives the control component to rotate in order to control the raising and lowering of the door / window body.

[0027] According to a preferred embodiment, the control component includes a pivoting member and a lifting rod, one end of the lifting rod being rotatably connected to the pivoting member, and the other end being a free end;

[0028] The lifting rod has a lifting position and a lowering position, and the handle rotates the pivot member to drive the lifting rod to switch between the lifting position and the lowering position.

[0029] According to a preferred embodiment, it further includes a second end pulley group and a first connecting rod, wherein the second end pulley group and the first end pulley group are disposed at both ends of the intermediate pulley group;

[0030] One end of the first connecting rod is connected to the free end of the lifting rod, and the other end is connected to the second end pulley group. The control component acts on the first end pulley group, the second end pulley group, and the intermediate pulley group.

[0031] With this configuration, the control components can control the state changes of the first end pulley group, the second end pulley group, and the middle pulley group with the main body of the door and window, enabling the main body of the door and window to switch between two states: sinking and lifting.

[0032] According to a preferred embodiment, the device further includes a lock box, the lock box including a driving member and a transmission member, the driving member being rotatably connected to the transmission member;

[0033] The transmission component is provided in two parts, which are arranged parallel to each other on both sides of the axial direction of the drive component. When the drive component rotates, the two transmission components move away from or towards each other.

[0034] In summary, the lifting sliding door and window provided by the present invention has at least the following technical effects:

[0035] 1) The middle pulley group is equipped with elastic elements. In actual application environment, the first end pulley group and the middle pulley group can adjust the height and level of the door and window body, so that the door and window body fits tightly with the casing structure in the horizontal and vertical directions, ensuring good airtightness. At the same time, if the door and window body is equipped with a lock box, it can also ensure the normal locking and unlocking of the lock box, bringing a good user experience.

[0036] 2) The first end pulley group includes an adjustment component, which includes an end seat and a second movable shaft hole. In order to adjust the height of the movable wheel, the position of the adjustment component can be adjusted in the horizontal direction so that the position of the movable shaft in the second movable shaft hole changes, thereby changing its position in the first movable shaft hole, and thus changing the height of the movable wheel. Compared with the adjustment in the vertical direction, the horizontal adjustment is more convenient and reduces the difficulty of operation.

[0037] 3) The lifting and sliding doors and windows are locked at multiple points through a lock box with bidirectional transmission function, thereby enhancing the sealing performance of the lifting and sliding doors. Attached Figure Description

[0061] Please refer to the following: Figure 1 and Figure 2 This invention discloses a lift-and-slide door and window, including a door and window body 1, a handle 2, a control component 5, a lock box 6, a lifting mechanism, and a pulley mechanism. The pulley mechanism is located on the bottom surface of the door and window body 1 and is used to support and drive the door and window body 1 to slide. One end of the lifting mechanism is connected to the control component 5, and the other end is connected to the pulley mechanism. The handle 2 is rotatably connected to the control component 5, and the lock box 6 is drively connected to the control component 5. By rotating the handle 2, the handle 2 drives the inside of the control component 5 to rotate. The control component 5 can control the state changes of the pulley mechanism and the door and window body 1, and can switch between two states: sinking and lifting.

[0062] Specifically, the pulley mechanism includes a first end pulley group 3, a second end pulley group 9, and an intermediate pulley group 4. The first end pulley group 3 and the second end pulley group 9 are respectively located at both ends of the intermediate pulley group 4. The intermediate pulley group 4 is not necessarily located in the middle of the door / window body 1, but is located at a non-end location, and the intermediate pulley group 4 is provided as at least one set; the pulley group located at the end furthest from the handle 2 is defined as the first end pulley group 3. Please refer to the following: Figures 3 to 5The first end pulley assembly 3 includes a first cover plate 32, a first support base 33, pulleys, a first connector 31, and an adjustment assembly 36. The first connector 31 is used to connect the profile to drive the door and window body 1 to move. The first cover plates 32 are fixed in pairs at both ends of the first connector 31. There are two pulleys, which are clamped and movably connected to the two first cover plates 32. The first support base 33 is also clamped between the two first cover plates 32 and is used to support the door and window body 1 in the vertical direction. The first connector 31 and the adjustment assembly 36 are respectively located at both ends of the first cover plate 32 in the sliding direction of the pulley to ensure the stability of the movement of the first end pulley assembly 3.

[0063] More specifically, the first end pulley assembly 3 in this embodiment further includes a first guide wheel 332. A first guide rail 331 is provided on the first support base 33. The first guide wheel 332 is slidably connected to the first guide rail 331 to realize the lifting and lowering of the pulley. The axis of the first guide wheel 332 is rotatably connected to the first cover plate 32. The movement direction of the first guide wheel 332 within the first guide rail 331 is the movement direction of the first baffle relative to the first support base 33. One of the two pulleys is configured as a fixed pulley 34, and the other is configured as a movable wheel 35. A movable shaft 37 passes through the axis of the movable wheel 35. A first movable shaft hole 323 is provided on the first cover plate 32. The movable shaft 37 passes through the first movable shaft hole 323 and the adjusting component 36. The extension direction of the first movable shaft hole 323 is vertical, that is, the movable wheel 35 can move vertically relative to the first cover plate 32. The adjusting component 36 adjusts the movable shaft 37 in the first movable shaft hole 323. The internal position; the adjustment component 36 includes an end seat 361, on which a second movable shaft hole 3611 is provided. The angle between the extension direction of the second movable shaft hole 3611 and the horizontal direction is configured to be greater than 0° and less than 90°, that is, not parallel to the horizontal and / or vertical directions. The movable shaft 37 passes through both the first movable shaft hole 323 and the second movable shaft hole 3611. During the movement of the movable shaft 37 along the second movable shaft hole 3611, changes in both the horizontal and vertical directions are realized simultaneously. Since the extension direction of the first movable shaft hole 323 is vertical, that is, by adjusting the position change of the movable shaft 37 relative to the second movable shaft hole 3611, the position change of the movable wheel 35 relative to the first movable shaft hole 323 in the vertical direction can be adjusted, converting horizontal movement into vertical movement. Compared with directly adjusting the height of the movable wheel 35 in the vertical direction, the indirect adjustment in the horizontal direction is more convenient, reduces the difficulty of operation, and facilitates operation by the user.

[0064] It is understood that both pulleys 432 can also be configured as movable wheels 35. The structure and operation of the movable wheel 35 are described in the above description of the movable wheel 35, and will not be elaborated further here. Such modifications are all within the protection scope of this invention.

[0065] Specifically, one of the first cover plate 321 and the end seat 361 is provided with a guide protrusion 321, and the other is provided with a guide groove 3612 at a corresponding position. The guide protrusion 321 and the guide groove 3612 are slidably connected. In this embodiment, the guide protrusion 321 is provided on the first cover plate 32, and the guide groove 3612 is provided on the end seat 361. The extension direction of the guide groove 3612 is horizontal. In short, the horizontal movement of the end seat 361 is converted into the vertical movement of the movable wheel 35. To further ensure the stability of the horizontal movement between the end seat 361 and the first cover plate 32, a positioning block 322 is also provided on the first cover plate 32. The positioning block 322 is arranged in the horizontal direction to limit the relative displacement between the end seat 361 and the first cover plate 32 in the vertical direction. The end of the movable shaft 37 passing through the first movable shaft hole 323 and the second movable shaft hole 3611 is fitted with a fastening sleeve 371 for positioning the movable shaft 37, and the fastening sleeve 371 abuts against the end seat 361.

[0066] Furthermore, a first engaging block 362 is provided between the two first cover plates 32. The adjustment assembly 36 also includes an adjustment pin 363. The adjustment pin 363 passes through the through hole 3613 of the end seat 361 and the first engaging block 362 in the horizontal direction. The first engaging block 362 is configured to pass through. By rotating the adjustment pin 363, the distance between the first engaging block 362 and the end of the adjustment pin 363 in the horizontal direction is changed. During this process, the adjustment pin 363 pushes the end seat 361 to move in the horizontal direction along the guide protrusion 321 and the guide groove 3612. The position of the movable shaft 37 relative to the second movable shaft hole 3611 changes, thereby adjusting the position of the movable wheel 35 relative to the first movable shaft hole 323 in the vertical direction. In general, the movement state of the first end pulley group 3 in this embodiment can be regarded as converting horizontal movement into vertical movement. This setting method is convenient for users to operate.

[0067] Furthermore, an anti-loosening element 364 is fitted on the adjusting pin 363. In this embodiment, the anti-loosening element 364 is a return spring. When it is assembled between the adjusting pin 363 and the first locking block 362, the anti-loosening element 364 is in a compressed state, applying axial pressure to the adjusting pin 363 to prevent the adjusting pin 363 from rotating on its own and causing the height of the movable wheel 35 to change.

[0068] Furthermore, please refer to the following: Figures 6 to 8The intermediate pulley group 4 includes a second cover plate 41, a second support base 42, a pulley assembly 43, and a second connector 44. The second connector 44 is used to connect the profile to drive the door and window body 1 to move. The second cover plates 41 are fixed in pairs at both ends of the second connector 44. The pulley assembly 43 is clamped and movably connected to the two second cover plates 41. The second support base 42 is also clamped and disposed between the two second cover plates 41 to support the door and window body 1 in the vertical direction. The number of second connectors 44 is also configured to be two, which are respectively disposed at both ends of the second cover plates 41 in the sliding direction of the pulley assembly 43 to ensure the stability of the movement of the intermediate pulley group 4.

[0069] Furthermore, the intermediate pulley assembly 4 in this embodiment also includes an elastic element 45. One end of the elastic element 45 is fixedly connected to the second connecting member 44, and the other end is fixedly connected to the pulley assembly 43. The pulley assembly 43 includes a base 431 and a pulley 432. The pulley 432 is rotatably connected to the base 431. In this embodiment, the number of pulley assemblies 43 is configured to be two. When the intermediate pulley assembly 4 in this embodiment is connected to the door and window body 1, the weight of the door and window body 1 is converted into pressure on the second support seat 42. Since the second support seat 42 is movably connected to the second cover plate 41, the pressure on the second support seat 42 is transmitted to the second cover plate 41. The pulley assembly 43 is connected to the second cover plate 41, so the pulley assembly 43 also bears the pressure on the second support seat 42. When the intermediate pulley assembly 4 maintains horizontal movement on the slide rail (not shown in the figure), the pressure of the door and window body 1 on the pulley assembly 43 is equal to the initial tension of the elastic element 45. The elastic element 45 maintains its initial length. The pulley assembly 43 is evenly stressed. When there is an obstacle or a protrusion in the slide rail where the intermediate pulley group 4 is located, most of the weight of the door and window body 1 is applied to the pulley 432 when the pulley 432 passes over the obstacle or protrusion, resulting in greater pressure on the pulley 432. If the pressure is greater than the initial tension of the elastic element 45, the elastic element 45 will deform, and the pulley assembly 43 will rotate relative to the second cover plate 41 to balance the pressure on each pulley 432, thereby reducing the pressure on a single pulley 432, preventing the pulley 432 from jamming or being damaged, and extending the service life of the pulley 432. When the pulley 432 returns to the horizontal track from the obstacle or protrusion (i.e., when the force height of the pulley 432 changes), the pulley assembly 43 vibrates. The elastic element 45 can extend and retract to absorb the energy of the vibration until the elastic element 45 returns to its original shape, thereby achieving the effect of shock absorption and ensuring the operational stability of the intermediate pulley group 4.

[0070] When the movable wheel 35 of the first end pulley group 3 is adjusted in height, due to the large size of the door and window body 1, even if the adjustment range of the height of the first end pulley group 3 is small, the overall height and levelness will change significantly. Under the action of the elastic element 45, the pulley assembly 43 rotates relative to the second cover plate 41 to balance the pressure of the door and window body 1, keep the bottom surface of the door and window body 1 horizontal, and ensure that the door and window body 1 fits tightly with the casing structure in both the horizontal and vertical directions, ensuring good airtightness. At the same time, it can also ensure the normal locking and unlocking of the lock box 6, providing users with a good user experience.

[0071] More specifically, the intermediate pulley assembly 4 also includes a second guide wheel 422. A second guide rail 421 is provided on the second support base 42. The second guide wheel 422 is slidably connected to the second guide rail 421. A second fixing pin 423 passes through the second guide wheel 422. A fixing hole 414 is provided at a corresponding position on the second cover plate 41. Both ends of the second fixing pin 423 are fixed to the fixing holes 414 on the two second cover plates 41. In this embodiment, the axes of the two pulleys 432 are symmetrically arranged about the second fixing pin 423. It can be understood that the number of pulley assemblies 43 is not fixed. In this embodiment, one pair is used, but two or more pairs can also be used, as long as the elastic force of the elastic element 45 ensures that each pulley 432 is subjected to balanced force. Figure 6 As shown, Figure 6 The second guide wheel 422 is located above the second guide rail 421, that is, the second fixing pin 423 and the second cover plate 41 connected to the second guide wheel 422 are located above the second support base 42, at which time the intermediate pulley group 4 is in an unlifted state; when the second guide wheel 422 rolls diagonally downward along the second guide rail 421, that is, the second fixing pin 423 and the second cover plate 41 move diagonally downward relative to the second support base 42, until the second guide wheel 422 moves to the lowest point of the second guide rail 421, the upper surface of the second support base 42... When the vertical distance between the surface and the axis of pulley 432 reaches its maximum, the intermediate pulley group 4 is in the lifting state. During the transition from the unlifted state to the lifting state, or from the lifting state to the unlifted state, the force between the second connecting member 44 and the pulley assembly 43 is dynamic. That is, the elastic force applied by the elastic member 45 to the second connecting member 44 and the pulley assembly 43 is also dynamic. The elastic member 45 can freely extend and retract to absorb the energy of vibration, thereby achieving the effect of shock absorption and ensuring the stability of the intermediate pulley group 4 during dynamic changes.

[0072] It is understood that the elastic element 45 of the present invention can be configured as a return spring or a gas spring. In this embodiment, a return spring is selected because it is cheaper and its mechanical fatigue life is usually greater than that of a gas spring, thereby extending the overall service life of the intermediate pulley group 4.

[0073] Furthermore, the second connector 44 and the second cover plate 41 are connected by a snap-fit ​​connection. One of them is provided with a plug-in portion 411, and the other is provided with a second snap-fit ​​block 443. The shape and size of the plug-in portion 411 and the second snap-fit ​​block 443 are matched to realize the snap-fit ​​connection. In this embodiment, the plug-in portion 411 is provided at both ends of the second cover plate 41, and the second snap-fit ​​block 443 is provided on the second connector 44. Of course, the plug-in portion 411 can also be provided on the second connector 44, and the second snap-fit ​​block 443 can be provided on the second cover plate 41. As an optional implementation, the second connector 44 and the second cover plate 41 can also be configured as a tenon and mortise connection. Such variations are all within the protection scope of this invention.

[0074] Specifically, a hub 433 passes through the axle of pulley 432, and a positioning hole 412 is provided on the second cover plate 41. The hub 433 passes through and is positioned in the positioning hole 412. A fixing sleeve 434 is also fitted at the end of the hub 433. The fixing sleeve 434 abuts against the second cover plate 41 to further position the pulley 432 and prevent the pulley 432 from disengaging from the base 431 under repeated vibrations during the repeated lifting and lowering of the intermediate pulley group 4. On the other hand, a convex shaft 413 is provided on one of the base 431 and the second cover plate 41. The other side is provided with a shaft hole 4311, through which a convex shaft 413 passes and is rotatably connected to the shaft hole 4311. In this embodiment, the convex shaft 413 is provided on the second cover plate 41 and the shaft hole 4311 is provided on the base 431. Of course, the convex shaft 413 can also be provided on the base 431 and the shaft hole 4311 can be provided on the second cover plate 41. Such variations are all within the protection scope of this invention. More preferably, a bearing can be provided between the convex shaft 413 and the shaft hole 4311 to reduce the friction during the rotation of the base 431 and the second cover plate 41 and maintain the stability of the movement.

[0075] Furthermore, please refer to Figure 8 The base 431 is provided with a first fixing post 4312, and the second connecting member 44 is provided with a second fixing post 444. The terms "first" and "second" are only used to distinguish between the first fixing post 4312 and the second fixing post 444, and do not imply any structural difference between them. One end of the elastic member 45 is fixedly connected to the first fixing post 4312, and the other end is fixedly connected to the second fixing post 444. When there is an obstacle in the slide rail where the two pulleys 432 are located, or when the slide rail itself has a protrusion, when the pulley 432 passes over the obstacle or protrusion, most of the weight of the door / window body 1 is applied to the pulley 432, resulting in greater pressure on the pulley 432, and thus greater pressure. Figure 8Taking the left pulley 432 as an example, if the pulley 432 passes over an obstacle or protrusion, the pressure it receives is greater than the initial tension of the elastic element 45. The base 431 rotates clockwise relative to the second cover plate 41. The elastic element 45, which is positioned on the base 431, is squeezed by the first fixed column 4312 and the second fixed column 444. The elastic element 45 deforms to balance the pressure on the pulley 432, thereby reducing the pressure on the left pulley 432, preventing the pulley 432 from getting stuck or damaged, and extending the service life of the pulley 432.

[0076] The second connector 44 is also provided with a plug-in groove 441 and a fixing groove 442. The plug-in groove 441 is used to connect the profile in the sliding direction of the pulley 432. That is, when there are multiple intermediate pulley groups 4, the profile can be plugged in through the plug-in groove 441 to increase the number of additional intermediate pulley groups 4. The fixing groove 442 is used to plug in and connect with a brush (not shown in the figure). When the intermediate pulley group 4 slides along the slide rail, the brush can clean the obstacles on the slide rail in advance, reducing the probability of the pulley 432 running over the obstacles.

[0077] Specifically, please refer to the following: Figures 12 to 15 The control component 5 includes a first housing 51, a second housing 52, side plates 53, a pivoting member 54, a lifting rod 55, and an external connector 56. The first housing 51 and the second housing 52 are closed to form an installation space between them. The pivoting member 54 and at least part of the lifting rod 55 are disposed in this installation space. The pivoting member 54 is a cuboid block structure. The rotation of the pivoting member 54 is determined by the first housing 51 and the second housing 52. The side plates 53 are arranged in pairs, and the two side plates 53 clamp the first housing 51 and the second housing 52. Bolts pass through the two side plates 53, the first housing 51, and the second housing 52 and are tightened with nuts to achieve a tight fit between the first housing 51 and the second housing 52; or, the two side plates 53, the first housing 51, and the second housing 52 are fixed together by means of fixed posts. 52 is passed through, and then the two ends of the fixing post are fixed. In this embodiment, the fixing post is configured as the first positioning member 57 and the second positioning member 58. One end of the lifting rod 55 is rotatably connected to the rotating member 54, and the other end is the free end of the lifting rod 55. The free end is hinged to the external member 56. The lifting rod 55 has a lifting position and a sinking position. The rotating member 54 rotates to make the lifting rod 55 switch between the lifting position and the sinking position. More importantly, the two ends of the lifting rod 55 located in the lifting position (that is, the end of the lifting rod 55 that is hinged to the rotating member 54 and the free end of the lifting rod 55) and the rotation center of the rotating member 54 are aligned. The handle 2 is inserted into the rotating member 54. In this way, by rotating the handle 2 to rotate the rotating member 54, the lifting position and the sinking position can be switched.

[0078] At least one of the first housing 51 and the second housing 52 is provided with a sliding groove 511. The external connector 56 is provided with a slider 561, which is slidably connected to the sliding groove 511. Along the sliding direction of the slider 561, the center line of the sliding groove 511 is located directly below the rotation center of the indexing member 54. During the movement of the lifting rod 55 from the lowered position to the lifted position, the lower end of the lifting rod 55 drives the slider 561 to slide vertically in the sliding groove 511. Therefore, the lower end of the lifting rod 55 is always located below the rotation center of the indexing member 54. It should be noted that the control component 5 also includes an abutment block 59, which is connected to the external connector 56. When the lifting rod 55 is in the lifted position... When in the lowered position, the top of the abutment block 59 abuts against the bottom surface of the first housing 51 and the second housing 52. Furthermore, the first positioning member 57 and the second positioning member 58 are disposed on the inner wall of the first housing 51 or the second housing 52. When the lifting rod 55 is in the lowered position, the rotating member 54 abuts against the second positioning member 58. When the lifting rod 55 is in the lowered position, along the rotation direction of the rotating member 54, one side wall of the rotating member 54 abuts against the second positioning member 58, thus completing the positioning of the rotating member 54 in the lowered position. Similarly, when the lifting rod 55 is in the lifted position, one side wall of the rotating member 54 abuts against the first positioning member 57, thus completing the positioning of the rotating member 54 in the lifted position. Figure 14 With the lifting lever 55 in the lowered position. Figure 15 With the lifting rod 55 in the lifted position, in both of these states, both ends of the lifting rod 55 (that is, the end where the lifting rod 55 is hinged to the rotating member 54 and the free end of the lifting rod 55) and the rotation center of the rotating member 54 are aligned. Therefore, the weight of the door and window body 1 borne by the lifting rod 55 is directly applied to the rotation center of the rotating member 54 through the rotating member 54, which enhances the support strength of the rotating member 54 and effectively prevents the rotating member 54 from rotating downward.

[0079] Please refer to the following: Figure 9 The lifting mechanism of the sliding door and window in this embodiment includes a first connecting rod 7, a limiting block 8, and a second connecting rod 10. One end of the first connecting rod 7 is hinged to the abutment block 59 of the control component 5, and the other end is hinged to the limiting block 8. One end of the second connecting rod 10 is hinged to the limiting block 8, and the other end is hinged to the second end pulley group 9. The control component 5 lowers or raises the pulley group through the lifting mechanism. The first connecting rod 7 and the second connecting rod 10 are configured to be of variable length in the length direction. The term "variable length" here refers to cutting the first connecting rod 7 and / or the second connecting rod 10 according to the actual required length, or configuring it to be telescopic, telescopicating the first connecting rod 7 and / or the second connecting rod 10 according to the actual required length, or configuring the first connecting rod 7 and / or the second connecting rod 10 to be a long rod of the required length spliced ​​together from multiple short rods. Such transformations all fall within the protection scope of this invention.

[0080] Several limiting blocks 8 are provided and sleeved on the first connecting rod 7 and / or the second connecting rod 10. The limiting blocks 8 are slidably connected to the profile of the door and window body 1, and the shape and size of the profile in the guiding direction match the limiting blocks 8 to ensure that the first connecting rod 7 and / or the second connecting rod 10 can move stably in the cavity inside the profile during the movement, avoid shaking, and improve the movement stability.

[0081] Please refer to the following for details. Figure 10 and Figure 11 In this embodiment, the lock box 6 for lifting sliding doors and windows includes a base 61, a drive member 62, and a transmission member 63. The drive member 62 is located inside the base 61 and can rotate relative to the base 61. The drive member 62 is rotatably connected to the transmission member 63. There are two transmission members 63, which are arranged parallel to each other on both sides of the axial direction of the drive member 62. When the drive member 62 rotates, the two transmission members 63 move away from or towards each other. A connecting block 65 is provided on the transmission member 63. Please refer to the attached document. Figure 16 In this embodiment, the lifting sliding door also includes a transmission rod 100 and a locking block 110. One end of the transmission rod 100 is fixedly connected to the connecting block 65, and the other end is connected to the locking block 110. The locking block 110 is used to lock and connect with the locking point on the door frame casing profile. The transmission component 63 near the door and window body 1 is also provided with a plug-in component 64. The base 61 is connected to the door and window body 1, and the plug-in component 64 is engaged with the abutment block 59 of the control component 5. By rotating the handle 2, the transmission component 63 is driven to move. During the movement of the transmission component 63, the driving component 62 rotates, thereby driving the transmission component 63 on the other side to move as well, realizing double-end locking or unlocking, and enhancing the sealing performance of the lifting sliding door.

[0082] In summary, the lifting sliding door and window provided by the present invention has at least the following technical effects:

[0083] The middle pulley group 4 is equipped with an elastic element 45. In actual application environment, the first end pulley group 3 and the middle pulley group 4 can adjust the height and level of the door and window body 1, so that the door and window body 1 fits tightly with the sleeve structure in the horizontal and vertical directions, ensuring good airtightness. At the same time, if the door and window body 1 is equipped with a lock box 6, it can also ensure the normal locking and unlocking of the lock box 6, bringing a good user experience.

[0084] The first end pulley group 3 includes an adjustment component 36, which includes an end seat 361. The end seat 361 is provided with a second movable shaft hole 3611. In order to adjust the height of the movable wheel 35, the position of the adjustment component 36 can be adjusted in the horizontal direction, so that the position of the movable shaft 37 in the second movable shaft hole 3611 changes, thereby changing its position in the first movable shaft hole 323, and thus changing the height of the movable wheel 35. Compared with the adjustment in the vertical direction, the horizontal adjustment is more convenient and reduces the difficulty of operation.

[0085] The lock box 6, which has a two-way transmission function, enables multi-point locking of the lifting sliding door and window, thereby enhancing the sealing performance of the lifting sliding door.

[0086] The technical means disclosed in this invention 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 principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
