[0034] See also Figures 1 to 6 This embodiment discloses a fixing member, which includes a fixing member body 2, which is provided with a fixing screw hole 21, and the fixing screw hole 21 is used to connect the suspension rod 32 of the hanging box assembly 3; the fixing member body 2 can rotate around the axis of the fixing screw hole 21 between a first position and a second position; when the fixing member body 2 is rotated to the first position, the fixing member body 2 is used to be installed in the first guide groove 11 of the track frame 1 and can move along the first guide groove 11; when the fixing member body 2 is rotated to the second position, the fixing member body 2 is used to be clamped in the first guide groove 11.

[0035] The fixing member disclosed in this embodiment, on the one hand, can be rotated to the first position relative to the first guide groove 11 to be easily installed and moved along the groove, and then rotated to the second position to be locked after finding the best installation position. This design not only increases the flexibility of installation, but also greatly facilitates on-site installation operations, reducing installation time and labor costs; on the other hand, after the fixing member body 2 is locked in the first guide groove 11, rotating the hanger 32 can make the hanger 32 move up and down along its own axis, so that the relative position of the fixing member body 2 and the hanging box body 31 in the up and down directions can be adjusted, thereby achieving the purpose of adjusting the height of the fixed door and window sash 5, and after the height of the fixed door and window sash 5 is adjusted, the support assembly 4 can be placed against the support surface to further stabilize the position of the fixed door and window sash 5. In this way, through the cooperation of the fixing member body 2 and the hanging box assembly 3, not only can the fixed door and window sashes 5 of different specifications and types be quickly hung and set. The purpose of positioning and installation is, at the same time, through the hanging positioning of the fixing body 2 and the hanging box assembly 3 and the rotation of the hanging rod 32 to adjust the height of the fixed door and window sash 5, the entire installation and adjustment process can be made efficient and convenient, thereby improving the assembly efficiency and assembly quality, and when replacing fixed door and window sashes 5 of different specifications and types, there is no need to replace the fixing body 2 and the hanging box assembly 3, thereby greatly reducing the cost of later replacement and maintenance; on the other hand, by rotating the hanging rod 32 to raise the fixed door and window sash 5, the installation height of the fixed door and window sash 5 and the adjacent movable door and window sash can be kept consistent, thereby ensuring that the linkage parts on the movable door and window sash can be smoothly connected to the fixed door and window sash 5, thereby ensuring the stability of the movable door and window sash during movement. In this way, the same guide groove can be uniformly designed and manufactured to install the fixed door and window sash 5 and the movable door and window sash, the overall structure of the track frame 1 is simplified, and the design difficulty and production difficulty of the track frame 1 are reduced.

[0036] See also Figures 1 to 6 , this embodiment also discloses a door and window structure, the door and window structure includes a track frame 1, a fixing body 2, a hanging box assembly 3, a support assembly 4 and a fixed door and window sash 5, and also includes the above-mentioned fixing body 2; the track frame 1 is provided with a first guide groove 11; the fixing body 2 is provided with a fixing screw hole 21; when the fixing body 2 is rotated to a first position relative to the first guide groove 11, the fixing body 2 can be installed in the first guide groove 11 and can move along the first guide groove 11 to find a suitable installation position; when the fixing body 2 is rotated to a second position relative to the first guide groove 11, the fixing body 2 is clamped in the first guide groove 11; the hanging box assembly 3 includes a hanging box body 31 and a hanging rod 32, the hanging rod 32 is provided on the hanging box body 31, and the hanging rod 32 is threadedly connected to the fixing screw hole 21, and the axis of the hanging rod 32 is arranged along the up and down direction; the fixed door and window sash 5 is connected to the hanging box body 31; the support assembly 4 is provided at the lower end of the fixed door and window sash 5, and the support assembly 4 is used to abut and fix with the supporting surface. Specifically, the supporting surface here can be the ground, or the inner side surface of a guide rail installed on the ground.

[0037] like Figure 2 and Figure 3 As shown, specifically, in this embodiment, when installing the fixing body 2 and the hanging box assembly 3, the hanging rod 32 is first connected to the fixing screw hole 21 of the fixing body 2, and then the fixing body 2 is installed in the first guide groove 11 and the fixing body 2 is moved to the optimal installation position and then fixed in the first guide groove 11; indeed, in some other embodiments, the fixing body 2 can also be first installed in the first guide groove 11 and the fixing body 2 is moved to the optimal installation position and then fixed in the first guide groove 11, and then the hanging box assembly 3 is connected to the fixing body 2, and it can be selected according to actual needs.

[0038] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, specifically, in this embodiment, the first guide groove 11 includes a groove top wall 111, a groove bottom wall 112 and a groove side wall 113, the groove top wall 111 and the groove bottom wall 112 are arranged opposite to each other, and the groove side wall 113 is connected between the groove top wall 111 and the groove bottom wall 112; the groove bottom wall 112 is provided with a groove opening 117, and the hanger 32 extends into the first guide groove 11 from the groove opening 117; preferably, in this embodiment, the groove bottom wall 112 is provided with an extension rib 114 protruding toward the groove top wall 111, and a first limiting groove 115 is formed between the extension rib 114 and the groove side wall 113; limiting cantilevers 23 are respectively provided on both sides of the fixing body 2; when the fixing body 2 is rotated from the first position to the second position, the limiting cantilever 23 can pass over the extension rib 114 to be clamped in the first limiting groove 115. In this way, when the fixing body 2 is rotated to a position close to the second position, the limiting cantilever 23 can be engaged with the first limiting groove 115. In this way, the design of the limiting cantilever 23, the extension rib 114 and the first limiting groove 115 can also provide a certain guiding and positioning effect for the installation of the fixing body 2, thereby preventing the fixing body 2 that is not completely fixed in the second position from loosening easily, thereby helping the fixing body 2 to be more easily fixed in the first guide groove 11. Preferably, in this embodiment, the extension rib 114 and the first limiting groove 115 both extend along the length direction of the first guide groove 11.

[0039] like Figure 1 and Figure 2 As shown, preferably, in this embodiment, when the fixing body 2 is rotated to the second position, the rotating suspension rod 32 can make the bottom of the fixing body 2 press against the extension rib 114, so that the fixing body 2 is fully fixed in the second position within the first guide.

[0040] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, preferably, in this embodiment, the limiting cantilever 23 includes a cantilever body 231 and a protrusion 232. The cantilever body 231 is connected to the side wall of the fixing body 2, and the protrusion 232 is provided on the side of the cantilever body 231 close to the groove bottom wall 112. When the fixing body 2 rotates from the first position to the second position, the protrusion 232 can pass over the extension rib 114 to engage in the first limiting groove 115. The cantilever body 231 abuts against the groove side wall 113 to fix the fixing body 2 in the first guide groove 11. In this way, when the fixing body 2 rotates from the first position to the second position, the protrusion 232 will first contact the extension rib 114. As the fixing body 2 continues to rotate, the protrusion 232 will pass over the extension rib 114 and eventually be engaged in the first limiting groove 115. Moreover, when the fixing body 2 rotates to the second position, the cantilever body 231 will abut against the groove side wall 113, thereby further increasing the stability of the fixing body 2. This design not only helps to prevent the fixing body 2 from shaking or falling off in the guide groove, but also improves the strength and durability of the entire door and window structure.

[0041] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, preferably, in this embodiment, a second limiting groove 116 is recessed upwardly on the top wall 111 of the groove, and a limiting block 24 is protruded upwardly on the top of the fixing body 2, and the limiting block 24 moves synchronously with the fixing body 2; when the fixing body 2 is in the first position, the limiting block 24 can be inserted into the second limiting groove 116 and can move along the second limiting groove 116; when the fixing body 2 is in the second position, the limiting block 24 is fixed in the second limiting groove 116, specifically, at this time, the two sides of the limiting block 24 are respectively abutted against the two side walls of the second limiting groove 116. When the fixing body 2 is in the first position, the limit block 24 can be easily inserted into the second limit groove 116. At this time, the limit block 24 contacts the top of the second limit groove 116, but has not yet been abutted against the two side walls of the groove. This step provides a preliminary limiting effect for the subsequent movement of the fixing body 2; after confirming that the limit block 24 has been inserted into the second limit groove 116, the fixing body 2 can be moved along the first guide groove 11 to the desired position. In this process, the limit block 24 will move smoothly along the trajectory of the second limit groove 116 while maintaining contact with the top of the groove. This design ensures the stability and accuracy of the fixing body 2 during movement; when the fixing body 2 is rotated to the second position, the limit block 24 will be fixed in the second limit groove 116. At this time, the two sides of the limit block 24 are respectively abutted against the two side walls of the second limit groove 116, forming a stable support structure, thereby ensuring the ultimate stability and installation accuracy of the fixing body 2.

[0042] like Figures 1 to 5As shown, preferably, in this embodiment, an extension block 25 is protruding downward from the lower portion of the fixing body 2. The extension block 25 is located in the slot opening 117, and the fixing screw hole 21 extends through the extension block 25. This facilitates the connection between the suspension rod 32 and the fixing screw hole 21, and the assembly stability between the suspension rod 32 and the fixing screw hole 21 is also improved.

[0043] like Figure 2 、 Figure 3 and Figure 6 As shown, preferably, in this embodiment, the suspension rod 32 is rotatably mounted on the hanging box body 31; when the fixing body 2 is in the second position and secured within the first guide slot 11, the suspension rod 32 can rotate relative to the fixing screw hole 21 and can move up and down relative to the fixing screw hole 21. Driven by the suspension rod 32, the hanging box body 31 can move up and down relative to the fixing body 2. In this way, the suspension rod 32 can not only rotate relative to the fixing screw hole 21 but also move up and down relative to the fixing screw hole 21. In this way, the position of the hanging box body 31 can be adjusted to adjust the height of the fixed door and window sash 5 by rotating and moving the suspension rod 32 up and down, depending on the actual height of the fixed door and window sash 5 and installation requirements. This adjustment can be made within a certain range to meet different installation conditions.

[0044] like Figure 2 、 Figure 3 and Figure 4 As shown, preferably, in this embodiment, the fixing body 2 further defines a mounting groove 22 that communicates with the fixing screw hole 21. A gasket 34 is fixedly disposed within the mounting groove 22, through which the suspension rod 32 passes. Thus, the mounting groove 22 is designed to communicate with the fixing screw hole 21, and its shape and size match those of the gasket 34, ensuring that the gasket 34 is securely fixed within the mounting groove 22. The introduction of the mounting groove 22 and gasket 34 achieves a more stable and reliable connection between the suspension rod 32 and the fixing body 2, helping to prevent loosening or damage to the connection due to external forces. The presence of the gasket 34 also acts as a buffer and shock absorber, reducing friction and damage between the suspension rod 32 and the fixing body 2 caused by external forces. This helps extend the service life of the door and window structure and improves its impact resistance.

[0045] like Figure 2 and Figure 4 As shown, more preferably, in this embodiment, in order to improve the position stability of the gasket 34 in the installation groove 22 , a fixing rib 221 in contact with the gasket 34 is further provided in the installation groove 22 .

[0046] It should be noted that in some other embodiments, the hanger 32 can be a bidirectional screw, which is screwed to the fixing screw hole 21 and the hanging box body 31 respectively. When the bidirectional screw rotates, the fixing body 2 and the hanging box body 31 can be closer to or farther away from each other along the axial direction of the bidirectional screw to achieve the purpose of adjusting the height of the fixed door and window sash 5. It can be selected according to actual conditions.

[0047] like Figure 2 、 Figure 3 and Figure 6 As shown, in this embodiment, preferably, a worm gear 321 is provided at one end of the suspension rod 32. The hanging box assembly 3 also includes a worm 33, the axis of which is arranged horizontally. The worm 33 penetrates the hanging box body 31 and is meshed with the worm gear 321. When the worm 33 rotates, it drives the worm gear 321 to rotate. Driven by the worm 33, the suspension rod 32 can rotate relative to the fixing screw hole 21 and can move up and down relative to the fixing screw hole 21, thereby driving the hanging box body 31 up and down. This simplifies operation: by introducing the worm gear 321 and worm gear 33 transmission mechanism, installers can more easily achieve the up and down movement of the hanging box body 31. This, on the one hand, simply rotating the worm gear 33 can drive the suspension rod 32 and the hanging box body 31 to move, eliminating the need for complex adjustments and operations. The use of the worm gear 321 and worm gear 33 transmission mechanism makes the installation process more efficient and faster. The installers can complete the up and down movement and fixing of the hanging box body 31 in a short time, thereby improving work efficiency and installation quality; on the other hand, the worm gear 321 and worm 33 transmission mechanism has a self-locking feature, that is, after the worm 33 stops rotating, the worm gear 321 will maintain its current position unchanged. This feature enables the position of the hanging box body 31 to be more accurately controlled and fixed, avoiding accidental movement due to external force.

[0048] like Figure 2 、 Figure 3 and Figure 5 As shown, specifically, in this embodiment, when the fixing member body 2 is rotated to the first position relative to the first guide slot 11, the width dimension of the fixing member body 2 in the width direction of the slot opening 117 is smaller than the width dimension of the slot opening 117, and the fixing member body 2 can be installed into the first guide slot 11 from the bottom up through the slot opening 117. In this way, because the fixing member body 2 can easily enter the interior of the first guide slot 11 through the slot opening 117, the installer can complete the assembly of the fixing member body 2 without using complex tools or techniques. Therefore, the installation process is faster and more efficient, reducing the difficulty and cost of installation.

[0049] like Figure 2 、 Figure 3 and Figure 5As shown, preferably, in this embodiment, the door and window structure further includes a decorative cover 6, which is connected to the lower side of the track frame 1. Decorative covers 6 are distributed on both sides of the slot opening 117 in the width direction of the slot opening 117, with an opening 61 formed between the two decorative covers 6. Specifically, the width of the opening 61 is smaller than the width of the slot opening 117. When the fixing body 2 rotates relative to the first guide slot 11 to the first position, the width of the fixing body 2 is smaller than the width of the opening 61. The fixing body 2 can pass through the opening 61 and the first slot from top to bottom to be installed in the first guide slot 11. Thus, on the one hand, the introduction of the decorative cover 6 makes the overall appearance of the door and window structure more neat and beautiful. It cleverly conceals the slot opening 117 of the first guide slot 11, avoiding the visual disharmony caused by the exposure of the slot opening 117. On the other hand, the decorative cover 6 not only serves a decorative purpose but also has a certain practicality. It can protect the slot opening 117 from erosion and damage from the external environment, thereby extending the service life of the door and window structure.

[0050] like Figure 1 and Figure 7 As shown, preferably, in this embodiment, the support assembly 4 includes a mounting base 41, a connecting rod 42, and a supporting foot 43. The mounting base 41 is fixed to the lower end of the fixed door and window sash 5. The connecting rod 42 is threadedly connected to the mounting base 41 and fixedly connected to the supporting foot 43. The axis of the connecting rod 42 extends in the vertical direction. In this way, the relative position of the supporting foot 43 and the fixing base in the vertical direction can be adjusted by rotating the connecting rod 42 to adapt to the actual height and installation requirements of the fixed door and window sash 5. Preferably, in this embodiment, a rubber pad is provided on the side of the supporting foot 43 facing the supporting surface.

[0051] In addition, this embodiment also provides a linkage door system, which includes the door and window structure described above, and also includes movable door and window sashes, a sliding assembly, and a linkage member. The track frame 1 is provided with a second guide groove 12 parallel to the first guide groove 11. The sliding assembly is slidably arranged in the second guide groove 12. The movable door and window sashes are connected to the sliding assembly. The linkage member is arranged between the movable door and window sashes and the fixed door and window sashes 5. This linkage door system has all the advantages of the door and window structure described above, and will not be repeated here.

[0052] In summary, the fixing member disclosed in the present invention and the door and window structure including the fixing member can at least bring the following beneficial technical effects:

[0053] 1) The fixing body 2 can be rotated relative to the first guide groove 11 to a first position for easy installation and movement along the groove. After finding the optimal installation position, it can be rotated to a second position for locking. This design not only increases installation flexibility, but also greatly facilitates on-site installation operations, reducing installation time and labor costs.

[0054] 2) By hanging and positioning the fixing body 2 and the hanging box assembly 3 and rotating the hanging rod 32 to adjust the height of the fixed door and window sash 5, the entire installation and adjustment process can be made efficient and convenient, thereby improving assembly efficiency and assembly quality. Moreover, when replacing fixed door and window sashes 5 of different specifications and types, it is not necessary to replace the fixing body 2 and the hanging box assembly 3;

[0055] 3) The installation height of the fixed door and window sash 5 and the adjacent movable door and window sash can be kept consistent, thereby ensuring that the linkage parts on the movable door and window sash can be smoothly connected to the fixed door and window sash 5. The same guide groove can be uniformly designed and manufactured to install the fixed door and window sash 5 and the movable door and window sash, thereby simplifying the overall structure of the track frame 1.

[0056] 4) The design of the limiting cantilever 23, the extension rib 114 and the first limiting groove 115 can also provide a certain guiding and positioning effect for the installation of the fixing body 2, so that the fixing body 2 that is not completely fixed in the second position cannot be easily loosened, thereby helping the fixing body 2 to be more easily fixed in the first guide groove 11.

[0057] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
