For those skilled in the art, the specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0019] This embodiment discloses a door and window, including a window sash, a window frame, and a lifting device. The lifting device is provided between the window frame and the window sash, and the lifting device is provided with a lifting adjustment structure. The driving part and the winding part of the flexible traction member 10 of the lifting device are both connected to the window frame, and two lifting adjustment structures are respectively connected to both sides of the window sash. The flexible traction member 10 is driven by the driving part to extend and retract, thereby realizing the lifting or lowering of the window sash.

[0020] First Embodiment See Figure 1-3In the first embodiment, the lifting adjustment structure includes a fixed base 91, a connecting slider 92, and a tension adjustment member 93. The fixed base 91 is used to connect to the side wall of the window sash. The top plate 911 of the fixed base 91 is provided with a guide hole 912A through which the flexible traction member 10 passes. The connecting slider 92 is longitudinally slidably connected to the fixed base 91. The connecting slider 92 is used to adjust one end of the flexible traction member 10, and the other end of the flexible traction member 10 is used to connect to the lifting device of the flexible traction member 10. The tension adjustment member 93 is inserted through the top plate 911. The adjusting end and the abutting end of the tension adjustment member 93 are respectively provided on the inner and outer sides of the top plate 911. The abutting end of the tension adjustment member 93 abuts against the connecting slider 92 and is used to adjust the longitudinal displacement of the connecting slider 92.

[0021] The flexible traction component 10 can be made of steel wire rope. The fixed base 91 is a fixed base that supports the connecting components of the flexible traction component 10; it can be made of stamped or injection-molded metal. The guide hole 912A on the top plate 911 guides the direction of the flexible traction component 10, preventing friction between the flexible traction component 10 and the edge of the mounting base. The connecting slider 92 is a load-bearing component that slides vertically; it can be made of a metal block with a slide rail. Its sliding connection ensures the linear motion accuracy of the flexible traction component 10 during tension adjustment. The tension adjusting component 93 is a mechanical adjusting device with bidirectional force; it can be made of a bolt structure with external threads. The rotational motion is converted into linear displacement through thread engagement, and the pressure applied to the holding end precisely controls the slider position.

[0022] Specifically, after the flexible traction member 10 passes through the guide hole 912A of the top plate 911, its rope end is fixed to the connecting slider 92. When tension adjustment is required, the adjusting end of the tension adjusting member 93 is rotated, causing the supporting end to push the slider to slide along the inner wall of the mounting base. When the slider moves downward, the tensile tension of the flexible traction member 10 increases; when it moves upward, the tension is released. The guide hole 912A forms a path constraint on the flexible traction member 10, ensuring that the flexible traction member 10 always moves along a predetermined trajectory during adjustment. The sliding connection structure, in conjunction with the threaded adjustment mechanism, allows for fine-tuning of the tension without disassembling any components.

[0023] This application enables convenient and precise adjustment of the tension of the flexible traction component 10. During installation, the initial tension can be quickly adjusted by rotating the tension adjustment component 93. It also provides timely compensation should the flexible traction component 10 become slack during use, significantly improving system maintenance efficiency. The lifting and adjustment structure of this solution achieves high-precision linear adjustment within a limited space, while maintaining a compact structure and ease of operation.

[0024] In this embodiment, the guide hole 912A is a closed hole located on the surface of the top plate 911, and the closed hole does not contact the periphery of the top plate 911. A closed hole refers to a completely sealed hole structure, which can be circular, elliptical, or polygonal in shape, with continuous and uninterrupted hole walls. This structure provides a stable path for the flexible traction member 10, preventing lateral displacement during sliding, and effectively avoiding contact between the flexible traction member 10 and the window frame profile after installation, thus preventing friction and wear.

[0025] Furthermore, the lifting and adjusting structure also includes a clamping member 94, which is connected to the fixed base 91. The connecting slider 92 has a winding column 923 inside, and one end of the flexible traction member 10 is wound to the winding column 923 and then fixedly connected to the clamping member 94.

[0026] The winding column 923 refers to the columnar structure set on the connecting slider 92. Specifically, it can be implemented using a metal column with threads or grooves, used to wind the reversing flexible traction member 10. One end of the flexible traction member 10 is fixed to the surface of the winding column 923 by winding, for example, by winding it around the circumference of the column and then connecting it to the clamping member.

[0027] In this embodiment, the clamping member 94 includes a clamping rod 941 and a clamping head 942. The clamping rod 941 is connected to the fixed base 91, and the clamping head 942 is connected to the clamping rod 941. An irregular hole for squeezing and fixing one end of the flexible traction member 10 is provided between the clamping head 942 and the clamping rod 941.

[0028] The clamping component 94 is an assembly used to apply compressive pressure to the flexible traction component 10. Specifically, it can be implemented by combining a threaded metal rod with a pressure block. By tightening the clamping rod 941 and inserting one end of the flexible traction component 10 into the irregular hole of the clamping head 942, the rope end is clamped and fixed. The clamping rod 941 is a rod-shaped component that transmits adjustment force. Specifically, it can be implemented by a screw with external threads, and its end is fixed to the clamping head 942 by a threaded connection.

[0029] Specifically, after the rope end of the flexible traction component 10 is initially wound on the winding column 923, the clamping rod 941 is installed in the threaded hole on the side wall of the fixing seat 91. Then, the rope end of the flexible traction component 10 is inserted into the irregular hole of the clamping head 942. As the clamping rod 941 is screwed in, the rope end is gradually squeezed until it is fixed. When a wide range of length adjustment of the flexible traction component 10 is required, the clamping rod 941 is adjusted to loosen the rope end of the flexible traction component 10, and then the rope end is pulled to achieve a wide range of length adjustment.

[0030] This application enables rapid reinforcement of the rope head of the flexible traction component 10 after installation, effectively preventing rope head slippage caused by external impact or vibration. At the same time, the adjustable characteristics of the clamping rod 941 allow maintenance personnel to flexibly adjust the clamping force according to the actual working conditions, reducing the risk of system failure caused by rope head loosening.

[0031] In this embodiment, the connecting slider 92 includes a sliding plate 921 and a sliding shell 922. The sliding shell 922 and the sliding plate 921 surround a cavity that hides the flexible traction member 10. The rope end of the flexible traction member 10 and the winding post 923 that pass through the guide hole 912A are both located in the cavity.

[0032] The sliding plate 921 can be made of a rectangular metal plate and is used to support the rope head connection structure of the flexible traction member 10. The sliding shell 922 refers to the protective component covering the outside of the sliding plate 921, which can be made of a U-shaped sheet metal bending part, and together with the sliding plate 921, it forms a closed space. The two ends of the winding column 923 are connected to the sliding plate 921 and the sliding shell 922, respectively. The cavity refers to the accommodating space formed by the sliding shell 922 and the sliding plate 921, which can be achieved by welding the side wall of the shell to the edge of the sliding plate 921 to form a sealed structure, and is used to completely cover the connection part of the flexible traction member 10. This application achieves physical isolation protection of the connection part of the flexible traction member 10, preventing external environmental factors from interfering with the tension state of the flexible traction member 10, and ensuring the stability of the rope head connection structure during the lifting of the window sash. The synchronous movement of the cavity structure during adjustment ensures that the flexible traction member 10 is always in a controlled closed space, significantly improving the reliability of the lifting device in long-term use.

[0033] In this embodiment, the fixed base 91 is provided with a first sliding connection part 913, and the sliding plate 921 is provided with a second sliding connection part 9211. The first sliding connection part 913 and the second sliding connection part 9211 cooperate to realize the sliding connection between the sliding plate 921 and the fixed base in the vertical direction.

[0034] The first sliding connection 913 refers to a guide structure disposed on the inner wall of the fixed base 91, which can be implemented as a longitudinally extending guide rail or a groove, used to limit the movement trajectory of the sliding plate 921. The second sliding connection 9211 refers to a mating structure disposed on the outer wall of the sliding plate 921, which can be implemented as a groove matching the guide rail or a protrusion matching the groove, forming a sliding pair through mating with the first sliding connection 913. The mating relationship between the two ensures that the sliding plate 921 remains stable during up and down movement, preventing deviation or shaking.

[0035] This application solves the problems of easy displacement and unstable movement of the sliding component during the adjustment of the flexible traction component 10. The cooperation structure between the guide rail and the slide groove effectively controls the vertical movement accuracy of the sliding plate 921, reducing tension fluctuations in the flexible traction component 10 caused by component shaking during the adjustment process. The limiting function of the sliding pair also reduces collision wear between components and extends the service life of the adjustment structure.

[0036] In this embodiment, the tension adjusting member 93 is provided with an external thread structure, and the top plate 911 is provided with an internal thread structure, and the external thread structure and the internal thread structure mesh with each other.

[0037] When the tension adjusting member 93 is rotated, the meshing of the external and internal threads causes the adjusting member to displace vertically. The abutting end of the adjusting member pushes the connecting slider 92 to change the distance between it and the top plate 911, thereby adjusting the tension of the flexible traction member 10. The self-locking effect formed by the thread meshing can maintain the stability of the adjusted position and prevent displacement caused by vibration. This solution achieves stepless adjustment through the precise fit of the thread pair. Each rotation can obtain the displacement corresponding to the standard pitch. For example, when the pitch is 1 mm, a fine adjustment accuracy of 0.01 mm can be achieved.

[0038] In this embodiment, the lifting adjustment structure also includes a side pressure roller 95, which is rotatably connected to the fixed base. The roller surface of the side pressure roller 95 is used to contact the window frame to reduce friction.

[0039] During the window sash lifting process, the roller surface of the side pressure roller 95 remains in contact with the guide rail of the window frame. When the window sash undergoes lateral displacement, the side pressure roller 95 converts sliding friction into rolling friction through rotation. When the fixed base is subjected to the tension of the flexible traction member 10, the lateral pressure exerted by the side pressure roller 95 on the window frame is limited to the roller surface contact area, thereby avoiding direct friction between the window sash and the window frame.

[0040] Second Embodiment See Figure 4 In the second embodiment, unlike the first embodiment, one end of the flexible traction member 10 is fixedly connected to the connecting slider 92. Specifically, the connecting slider 92 is provided with multiple connecting holes, and the flexible traction member 10 is wound around the multiple connecting holes and then knotted onto the connecting slider 92.

[0041] The guide hole 912B is an opening located at the edge of the top plate 911, with the opening direction facing away from the window sash direction. The opening is located at the edge of the top plate 911, with the opening direction facing outward, so that the flexible traction member 10 can directly enter along the opening direction when inserted, avoiding interference with the side wall of the window sash.

[0042] Specifically, the guide hole 912B is designed as an opening structure on the edge of the top plate 911, with the opening direction opposite to the window sash movement direction. When the flexible traction member 10 is inserted from the outside, it can directly enter the connecting slider 92 through the opening, without needing to be inserted through the closed hole in the middle of the top plate 911. For example, the opening length can be 1 / 3 to 1 / 2 of the edge length of the top plate 911, and the opening width can be slightly larger than the diameter of the flexible traction member 10. During installation, the operator can slide the flexible traction member 10 laterally into the guide hole 912B along the opening, and then adjust the position of the connecting slider 92 using the tension adjustment member 93 to keep the flexible traction member 10 taut. This simplifies the tension adjustment process and improves installation efficiency.

[0043] In this solution, multiple winding posts 923 are used, and the rope end of the flexible traction member 10 can be directly wound and knotted onto the winding posts 923 without the need to add a clamping member 94.

[0044] The other technical features in the second embodiment are the same as those in the first embodiment, so they will not be described in detail here.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
