Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, specifically relating to a limiting structure and sliding doors and windows including the same. Background Technology

[0002] Sliding doors and windows in related technologies typically include door / window sashes, pulleys, and limiting wheels. Pulleys are usually located on the upper and / or lower sides of the door / window sash, supporting it and allowing it to slide along a preset track. Limiting wheels are fixed to the ground or a track. The horizontal frame of the door / window sash has mounting grooves extending along its length, and the two sides of the limiting wheels can respectively contact the two sides of the mounting grooves. The main functions of the limiting wheels are twofold: first, to provide guidance during the movement of the door / window sash, ensuring smooth sliding along the predetermined track; and second, to limit the swaying of the door / window sash, enhancing its stability.

[0003] However, in actual production, due to various factors such as processing precision, material properties, and design differences, the width of the mounting groove on door and window sashes may deviate to some extent. This deviation can lead to unstable cooperation between the limiting wheel and the mounting groove, specifically manifested as either too large or too small a gap between them. An excessively large gap will prevent the limiting wheel from effectively limiting the sash's movement, affecting its stability; a gap that is too small may obstruct the sash's movement, even causing jamming or preventing normal sliding, severely impacting the performance and user experience of sliding doors and windows. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a limiting structure and a sliding door and window including the same. By rotating the rotating member relative to the connecting seat to adjust the width between the two limiting parts, stable contact between the limiting parts and both sides of the mounting groove is achieved, thereby improving the guiding and stability of the sliding door and window.

[0005] The technical solution adopted by this utility model to solve its problem is: A limiting structure, applied to sliding doors and windows, includes: a connecting seat; a rotating member disposed on the connecting seat, the rotating member having two limiting parts, the rotating member being able to rotate relative to the connecting seat to adjust the width between the two limiting parts; the limiting member including a first limiting member and a second limiting member, the first limiting member and the second limiting member being located on both sides of the rotation center of the rotating member; the first limiting member and the second limiting member being able to simultaneously abut against the side wall of the rotating member to limit the rotation of the rotating member.

[0006] As an optional implementation, both limiting parts are rollers, the two rollers are spaced apart, and the rotating shafts of the two rollers are both vertically oriented.

[0007] As an optional implementation, both the first limiting member and the second limiting member are laterally inserted into the connecting seat.

[0008] As an optional implementation, both the first limiting member and the second limiting member are threadedly connected to the connecting seat.

[0009] As an optional implementation, the length of the first limiting member is greater than the length of the second limiting member.

[0010] As an optional implementation, the limiting structure also includes a mounting base connected to a connecting base. The mounting base has an oblong hole for providing position adjustment allowance when the mounting base is connected to an external component.

[0011] As an optional implementation, the rotating component includes a main body and two side ears, with the two side ears respectively disposed at opposite ends of the main body, and two limiting parts corresponding to each other disposed on the two side ears.

[0012] As an optional implementation, the connecting seat includes a connecting plate and a boss, the boss is disposed on the connecting plate, and the limiting member can be connected between the connecting plate and the rotating member; the rotating member is rotatably sleeved on the boss.

[0013] As an optional implementation, the connecting plate is provided with a clearance space, and the limiting member is located within the clearance space.

[0014] Based on the same inventive concept, this utility model also discloses a sliding door and window, including a door and window sash, a pulley and the aforementioned limiting structure. The pulley is disposed on the door and window sash, and the horizontal frame of the door and window sash is provided with an installation groove. When the width between the two limiting parts is adapted to the width of the installation groove, the two limiting parts respectively form contact with the two sides of the installation groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The width between the two limiting parts is adjusted by rotating the rotating part relative to the connecting seat, so that the limiting part can adapt to the door and window sash mounting grooves of different widths, and achieve a stable fit between the limiting part and the two sides of the mounting groove. This effectively solves the problems of unstable guidance, shaking and obstructed sliding caused by the width deviation of the mounting groove in the prior art, thereby improving the guiding stability and smoothness of sliding doors and windows.

[0027] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0028] See the embodiments of this utility model. Figures 1 to 4 As shown, a limiting structure is disclosed, including a connecting base 1, a rotating member 2, and a limiting member 3. The rotating member 2 is mounted on the connecting base 1 and has two limiting parts 21. The rotating member 2 can rotate relative to the connecting base 1 to adjust the width between the two limiting parts 21. The limiting member 3 is disposed between the connecting base 1 and the rotating member 2. When the rotating member 2 rotates to a position where the two limiting parts 21 can respectively abut against the two sides of the mounting groove of the horizontal frame of the door / window sash, the limiting member 3 acts on the rotating member 2 to restrict the rotation of the rotating member 2, keeping the rotating member 2 in the adjusted position. Through the above structure, the rotating member 2 can adjust the width between the two limiting parts 21, thereby adapting to mounting grooves of different widths, achieving stable contact between the two limiting parts 21 and the two sides of the mounting groove, and improving the smoothness and overall stability of the sliding of the door / window sash.

[0029] In one implementation, see [reference] Figure 1 As shown, the rotating component 2 is provided with two limiting parts 21, which are arranged at intervals. In this embodiment, both limiting parts 21 are rollers 211, and the rotation axis of the rollers 211 is arranged vertically. Through this vertically arranged roller structure, the rollers 211 form reliable contact with both sides of the mounting groove of the horizontal frame of the door and window sash during the sliding process, which can reduce the frictional resistance with the mounting groove while ensuring that the rotating component 2 can rotate, thereby improving the smoothness of sliding doors and windows. Optionally, the rollers 211 can be made of rubber, nylon, POM or metal to meet the requirements of wear resistance, quietness or load-bearing capacity in different application scenarios; In one implementation, see [reference] Figure 2As shown, the limiting member 3 includes a first limiting member 31 and a second limiting member 32, both of which are transversely inserted into the connecting seat 1 and located on both sides of the rotation center of the rotating member 2. The first limiting member 31 and the second limiting member 32 contact the side wall of the rotating member 2 and are used to limit the rotation of the rotating member 2 after it has been adjusted to a suitable position, thereby maintaining stable contact between the two limiting parts 21 and the sides of the mounting groove. Optionally, the first limiting member 31 and the second limiting member 32 can adopt various structures such as screws, pins, or elastic pins, and can be made of high-strength metal parts, engineering plastic parts, or composite materials according to different usage requirements to meet the load-bearing capacity and corrosion resistance requirements in different environments.

[0030] In one embodiment, both the first limiting member 31 and the second limiting member 32 are connected to the connecting seat 1 via threads, and can be reliably positioned by tightening after rotational adjustment. Further, in one embodiment, the length of the first limiting member 31 is greater than that of the second limiting member 32. This design of one long and one short member improves the limiting reliability in situations with limited assembly space. The longer first limiting member 31 provides deeper thread engagement and higher load-bearing capacity, used on the main load-bearing side to ensure limiting stability; the shorter second limiting member 32 avoids interference with surrounding components while achieving effective limiting, thus balancing reliability and assembly convenience in a compact structure. Optionally, the length difference between the first limiting member 31 and the second limiting member 32 can be adjusted according to different installation spaces to adapt to various door and window structural requirements; the length of the first limiting member 31 can be designed to be 1.2 to 1.5 times the length of a standard screw to enhance the fixing strength on the main load-bearing side; the second limiting member 32 can be shortened to the minimum length that only meets the limiting function, thereby further optimizing the overall structural compactness while ensuring the limiting effect.

[0031] In one embodiment, the limiting structure further includes a mounting base 4, which has an oblong hole 41. The oblong hole 41 provides position adjustment margin when the mounting base 4 is connected to the external component, accommodating different installation accuracy requirements. The mounting base 4 is connected to the connecting base 1 to fix the limiting structure to the external component. The external component can be a track, the ground, or other load-bearing components used for installing the limiting structure, depending on the actual application scenario. Optionally, the connection method between the mounting base 4 and the connecting base 1 can be any one of screw fastening, riveting, welding, snap locking, or integral molding; the oblong hole 41 can be an elongated hole, a bidirectional intersecting hole, or a stepped adjustment hole to adapt to different installation tolerance requirements.

[0032] In one embodiment, the rotating component 2 includes a main body 22 and two side ears 23, which are respectively disposed at opposite ends of the main body 22. Two limiting parts 21 are respectively mounted on the two side ears 23. This structure allows the two limiting parts 21 to be symmetrically distributed around the main body 22, thereby maintaining overall force balance when adjusting the spacing of the limiting parts 21. The two side ears 23 also provide greater rotation space for the rotating component 2 during the adjustment of the limiting parts 21, reducing interference with the connecting seat 1 or adjacent components, thereby improving the flexibility of assembly and adjustment. Optionally, the main body 22 can be cylindrical, prismatic, or elliptical; the side ears 23 can adopt a straight plate shape, an arc shape, or a structure with reinforcing ribs to adapt to the needs of different loads and spatial layouts.

[0033] In some embodiments, the mounting method between the roller 211's shaft and the side ear 23 can be any one of screw fastening, snap ring locking, bearing press fitting, or integral injection molding. Optionally, the limiting part 21 is not limited to the form of a roller; in other embodiments, it can be a slider or other structure capable of abutting against both sides of the mounting groove. Different forms can be selected according to actual needs. It should be noted that in some other embodiments, the roller 211's shaft can also be rotatably connected to the side ear 23, depending on actual needs.

[0034] In one embodiment, the connecting seat 1 includes a connecting plate 11 and a boss 12. The boss 12 is disposed on the connecting plate 11, and the rotating member 2 is rotatably fitted through the boss 12 to form a stable rotation fulcrum. A limiting member 3 passes through the connecting plate 11 and cooperates with the rotating member 2 to restrict the rotation of the rotating member 2. A clearance space 100 is provided on the connecting plate 11, and the limiting member 3 is located within the clearance space 100, thereby avoiding interference between the limiting member 3 and other components and improving the convenience and reliability of assembly. Optionally, the connecting plate 11 can be designed as a flat plate, a reinforcing rib plate, or an integral stamped structure according to the application scenario; the boss 12 can be integrally formed or realized by welding or screwing independent parts; the clearance space 100 can be in the form of a groove or a partial step to adapt to different assembly processes.

[0035] In one implementation, see [reference] Figure 2As shown, the rotating connector 200 sequentially passes through the rotating member 2, the boss 12, and the mounting base 4. Through the rotating connector 200, the rotating member 2 can rotate smoothly around the boss 12. The rotating connector 200 can take various forms such as screws, pins, rivets, bearing assemblies, or integrally formed shafts. Optionally, a bushing or sliding bushing can be provided between the rotating connector 200 and the rotating member 2 to reduce friction and improve durability. Fasteners 300 are used to fix the connecting base 1 and the mounting base 4, thereby ensuring the stability and vibration resistance of the limiting structure during use. Fasteners 300 can take various forms such as screws, bolts, self-tapping screws, or expansion screws.

[0036] In addition, this application also relates to a sliding door / window, including a door / window sash, rollers, and a limiting structure. The horizontal frame of the door / window sash has a mounting groove, and the rollers are disposed on the door / window sash and used to support and guide the door / window sash to move along the sliding track. The number of rollers can be single, double, or multiple, and the outer layer of the rollers can be a wear-resistant plastic layer, a rubber coating layer, or a metal roller structure. When the width between the two limiting parts 21 is adapted to the width of the mounting groove, the limiting parts 21 provide guidance and limit swaying during the sliding of the door / window sash, improving sliding stability and safety.

[0037] See Figure 3 and Figure 4 As shown, the distance between the two limiting parts 21 is defined as d, and the dashed line represents the sidewall of the mounting groove of the door / window sash horizontal frame. When the mounting groove is wide, the distance d between the two limiting parts 21 can be increased by rotating the rotating component 2, so that the limiting parts 21 reliably abut against both sides of the mounting groove; when the mounting groove is narrow, the distance d can be decreased by rotating the rotating component 2, so that the limiting parts 21 can also maintain stable contact with both sides of the mounting groove. Through this structural design, regardless of the tolerance deviation of the actual width of the mounting groove, it can be adapted by adjusting the distance d, thereby ensuring that the limiting parts 21 always maintain a stable fit with both sides of the mounting groove, improving the guiding and limiting effect, and ensuring the smoothness of the sliding of the door / window sash and the reliability of its use. Optionally, the shape of the mounting groove of the door / window sash horizontal frame is not limited to a rectangular groove, but can also be a V-shaped groove, a U-shaped groove, or a double-step composite groove structure. The shape of the limiting part 21 is designed to correspond to the sidewall of the mounting groove to ensure stable contact in different groove types. For example, when the mounting groove is a rectangular groove, the limiting part 21 can be a cylindrical roller 211 or a rectangular slider; when the mounting groove is a V-shaped groove, the limiting part 21 can be designed with a wedge-shaped contact surface to obtain a better self-positioning effect.

[0038] In other embodiments, the limiting structure not only limits the movement of door and window sashes but also provides a buffering function. The outer surface of the limiting part 21 may be covered with a flexible rubber layer or a polymer buffer material. When the door and window sashes slide rapidly to their limit position, the impact force is absorbed through elastic deformation, reducing noise and preventing damage to the edge of the mounting groove.

[0039] In summary, the limiting structure and the sliding door / window including it provided by this utility model have the following technical effects: (1) The structure design of the rotating part installed on the connecting seat and rotating relative to each other can adjust the width between the two limiting parts, thereby adapting to the mounting grooves of different widths. This effectively solves the problem that the limiting part and the mounting groove cannot make stable contact due to the deviation in the width of the door and window sash mounting groove, and improves the versatility and applicability of the limiting structure.

[0040] (2) By setting the limiting part between the connecting seat and the rotating part and locking it after the rotating part is adjusted to the target position, the two limiting parts are always in stable contact with both sides of the mounting groove during use. This not only provides reliable guidance during the sliding of the door and window sash, but also effectively limits the shaking of the door and window sash, and improves the smoothness and overall stability of the sliding door and window.

[0041] (3) The limiting structure consists of a small number of parts such as connecting seat, rotating part, limiting part and mounting seat. The overall structure is compact and the installation method is diverse. The mounting seat provides position adjustment margin through the waist-shaped hole to adapt to different assembly precision requirements, simplify the installation and debugging process, reduce production and assembly costs, and support a variety of door and window structures and different installation environments, thereby improving the versatility and ease of use of the sliding door and window system.

[0042] 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.
