Description

Technical Field

[0001] This utility model relates to the field of door and window hardware accessories, and in particular to anti-sway components and pulley mechanisms including them. Background Technology

[0002] Sliding doors, a common type of door in modern architecture, require stability and smooth operation. Anti-sway components, as an important part of sliding doors, are mainly used to reduce door swaying during opening and closing, improving stability and safety. The anti-sway component includes a base, a sliding member, a rotating member, and anti-sway wheel bodies. The sliding member is slidably mounted on the base, and the rotating member is hinged to the base. Anti-sway wheel bodies are located at both ends of the rotating member. The sliding member and the rotating member are connected by a transmission mechanism. By sliding the sliding member, the rotating member can be rotated left and right, thereby bringing the two anti-sway wheel bodies into contact with the side walls of the track groove.

[0003] Chinese Patent Publication No. CN216240219U discloses a pulley mechanism and door system, including: a base for fixing to a door leaf slot, the base having a first mounting hole; a rotating plate disposed on the base, with a first pulley and a second pulley respectively at both ends of the rotating plate, a second mounting hole between the first pulley and the second pulley on the rotating plate; and fasteners for passing through the second mounting hole and the first mounting hole to fix the rotating plate and the base to the door leaf slot. The rotating plate and the base are installed and fixed by setting the second mounting hole on the rotating plate between the first pulley and the second pulley, and correspondingly providing the first mounting hole on the base, and by using fasteners passing through the second mounting hole and the first mounting hole. The system also includes an adjusting plate disposed between the rotating plate and the base, and an adjusting structure for driving the adjusting plate to move horizontally. A slotted block engaging structure is provided between the adjusting plate and the rotating plate. When the adjusting structure drives the adjusting plate to move horizontally, the adjusting plate drives the rotating plate to rotate through the slotted block engaging structure, so that the angle of the rotating plate relative to the base changes. That is, the adjustment plate can be moved by adjusting the structure, and the rotation angle of the rotating plate can be controlled by the slotted block engaging structure, thereby realizing the pulley adjustment function of the pulley mechanism. This configuration has the advantage of convenient operation. The slotted block engaging structure includes an arc-shaped guide groove and a protrusion slidably connected to the arc-shaped guide groove. The protrusion is set on the rotating plate, and the arc-shaped guide groove is set on the adjustment plate. When the adjustment structure drives the adjustment plate to move, the arc-shaped guide groove is displaced, forcing the protrusion to move along the trajectory of the arc-shaped guide groove, thereby realizing the rotation of the rotating plate. This configuration has the advantages of simple structure and reliable operation. A second adjustment groove is provided on the adjustment plate, and fasteners pass through the second adjustment groove. This configuration allows the adjustment plate to be fixed on one side by fasteners, preventing the adjustment plate from shifting during movement.

[0004] The pulley mechanism described above has the same function as the anti-sway component. However, in this existing pulley mechanism, the adjusting plate drives the rotating plate to rotate through the slotted block locking structure. The slotted block locking structure is the transmission structure between the adjusting plate and the rotating plate. Since the slotted block locking structure and the second adjusting slot need to be arranged sequentially along the sliding direction of the adjusting plate, the length of the adjusting plate will be relatively long, which makes it difficult to reduce the overall length and volume of the pulley mechanism.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figures 1 to 5This embodiment discloses an anti-sway component 1, including a first base 11, a first sliding member 14, a first rotating member 12, and a first adjusting member 13. The first sliding member 14 is slidably disposed on the first base 11 along a first direction. The first sliding member 14 is provided with a guide groove 141 and a drive groove 142 extending in the same plane. The guide groove 141 extends along the first direction, and the extension direction of the drive groove 142 is inclined to or perpendicular to the first direction. The drive groove 142 and the guide groove 141 are arranged sequentially in a second direction. The second direction and the first direction are located in the same plane and are perpendicular to each other. The first rotating member 12 is connected by a rotating shaft 1. 21 is rotatably mounted on the first base 11. The rotating shaft 121 is located in the guide groove 141. Anti-sway wheel bodies 15 are provided at both ends of the first rotating member 12. The first rotating member 12 is provided with a transmission block 122, which is connected to the drive groove 142. The first adjusting member 13 is connected to the first sliding member 14 and can drive the first sliding member 14 to slide. Under the drive of the first sliding member 14, the guide groove 141 moves along the first direction and drives the transmission block 122 to rotate around the rotating shaft 121. Under the drive of the transmission block 122, the first rotating member 12 rotates left and right relative to the first base 11.

[0034] like Figure 1 and Figure 3 As shown, specifically, the drive groove 142 and the transmission block 122 are connected in a transmission manner. The drive groove 142 is disposed on the first sliding member 14 and slides synchronously with the first sliding member 14. The transmission block 122 is disposed on the first rotating member 12 and can drive the first rotating member 12 to rotate synchronously. The sliding of the drive groove 142 can drive the transmission block 122 to rotate around the rotating shaft 121 of the first rotating member 12, thereby causing the first rotating member 12 to rotate left and right.

[0035] It is understandable that the drive groove 142 and the transmission block 122 are the transmission structure provided between the first sliding member 14 and the first rotating member 12. In the prior art, there is a design in which the drive groove 142 and the guide groove 141 are arranged in the same direction (i.e., the first direction). Although this design realizes the transmission between the first sliding member 14 and the first rotating member 12 to a certain extent, since the drive groove 142 and the guide groove 141 both need to occupy a certain space, the length of the sliding member is often relatively long, which is not conducive to the miniaturization of the anti-sway component 1.

[0036] The anti-sway assembly 1 provided in this embodiment arranges the drive groove 142 and the guide groove 141 sequentially in a second direction. The second direction and the first direction are in the same plane and perpendicular to each other. This design cleverly utilizes the space in the plane, allowing the drive groove 142 and the guide groove 141 to coexist without increasing the length of the first sliding member 14, thereby significantly shortening the length of the first sliding member 14. This makes the entire anti-sway assembly 1 more compact and lightweight, suitable for the needs of more miniaturized doors. Furthermore, the reasonable arrangement of the drive groove 142 and the guide groove 141 also enables smooth and stable transmission between the first sliding member 14 and the first rotating member 12.

[0037] like Figure 2 and Figure 3 As shown, preferably, in this embodiment, the length of the drive groove 142 in the first direction is less than the length of the guide groove 141 in the first direction. The shorter drive groove 142 design facilitates the formation of an effective transmission connection between the drive groove 142 and the transmission block 122. Furthermore, while maintaining the same transmission performance, the shorter drive groove 142 helps to improve the compactness of the mechanical structure. This is especially important for applications with limited space, as the compact structural design can save valuable installation space while improving the overall stability and reliability of the machine.

[0038] like Figure 2 and Figure 3 As shown, more preferably, in this embodiment, the extending direction of the drive groove 142 is perpendicular to the first direction, and the projection of the drive groove 142 onto the second direction is located between the two ends of the guide groove 141. This arrangement, on the one hand, optimizes the spatial arrangement of the drive groove 142 and the guide groove 141, making full use of the limited space and effectively avoiding the problem of excessively long sliders caused by the drive groove 142 and guide groove 141 being arranged in the same direction in traditional designs. Furthermore, the projection of the drive groove 142 located between the two ends of the guide groove 141 further tightens the space. By combining different structures, the size and weight of the entire anti-sway assembly 1 are effectively reduced while maintaining functionality. On the other hand, the vertically arranged drive groove 142 and guide groove 141 form a more direct transmission path. When the first sliding member 14 slides along the first direction, the drive groove 142 can transmit force to the transmission block 122 more directly and effectively, thereby driving the first rotating member 12 to rotate around the rotating shaft 121. This design reduces energy loss and friction during transmission, improves transmission efficiency and stability, and enables the anti-sway assembly 1 to maintain stable performance during long-term use.

[0039] like Figure 2 and Figure 3As shown, preferably, in this embodiment, both anti-sway wheel bodies 15 are rotatably mounted on the first rotating member 12 via wheel axle 151. Both the rotating shaft 121 and the wheel axle 151 are vertically arranged. The rotating shaft 121 is located between the wheel axles 151 of the two anti-sway wheel bodies 15. The projections of the transmission block 122, the rotating shaft 121, and any wheel axle 151 onto the horizontal plane are not collinear. Thus, on the one hand, the vertical arrangement of the rotating shaft 121 and the wheel axle 151 allows the anti-sway wheel body 15 to rotate more stably around the axis when under force, reducing swaying and instability caused by axial offset or tilt. Furthermore, the rotating shaft 121 is located between the wheel axles 151 of the two anti-sway wheel bodies 15, forming a more balanced force distribution and improving the stability of the entire rotating component. On the other hand, the non-collinear design of the projections of the transmission block 122, the rotating shaft 121, and any wheel axle 151 onto the horizontal plane ensures the diversity and flexibility of the transmission path. This design allows the transmission block 122 to transmit torque to the rotating component more smoothly and efficiently when driven by the drive groove 142, thereby driving the anti-sway wheel body 15 to rotate. The non-collinear layout also reduces interference and friction during the transmission process, improving the efficiency and accuracy of the transmission.

[0040] like Figure 2 and Figure 3 As shown, more preferably, in this embodiment, the projections of the rotating shaft 121 and the axles 151 of the two anti-sway wheel bodies 15 onto the horizontal plane are collinear with the first straight line, while the projection of the transmission block 122 onto the horizontal plane is outside the first straight line. Thus, on the one hand, the collinear projections of the rotating shaft 121 and the axles 151 of the two anti-sway wheel bodies 15 onto the horizontal plane make the structure of the entire rotating component simpler and more compact. This design reduces unnecessary structural complexity and space occupation, which is beneficial for the miniaturization and weight reduction of the anti-sway component 1. On the other hand, the design that the projection of the transmission block 122 onto the horizontal plane is outside the first straight line ensures effective separation of the transmission path from the rotation axis. This layout reduces interference and friction during transmission, allowing the transmission block 122 to transmit torque to the rotating component more smoothly and accurately, thereby driving the anti-sway wheel body 15 to rotate.

[0041] like Figure 3As shown, preferably, in this embodiment, the cross-section of the transmission block 122 in the extending direction of the drive groove 142 is circular. Thus, on the one hand, when the circular cross-section transmission block 122 slides within the drive groove 142, it reduces the contact area with the groove wall, thereby reducing sliding friction resistance. This helps improve transmission efficiency, reduce energy loss, and make the mechanical structure more energy-efficient during operation. On the other hand, when the circular cross-section transmission block 122 slides within the drive groove 142, due to the characteristics of its shape, it can more effectively distribute the force, reducing vibration or swaying caused by excessive force at a single point. This helps enhance the smoothness of the mechanical structure's movement, especially in high-speed or high-precision applications. Furthermore, the design of the circular cross-section transmission block 122 simplifies the manufacturing process, as the circular shape is easier to achieve using standard machining methods (such as turning, milling, etc.). This also facilitates the assembly process, as the circular transmission block 122 is easier to slide and adjust its position within the drive groove 142.

[0042] It should be noted that in some other embodiments, the cross-section of the transmission block 122 in the extension direction of the drive groove 142 may also be, but is not limited to, elliptical or square, depending on the actual needs, and is not limited here.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, in this embodiment, the first adjusting member 13 is rotatably connected to the first seat 11 and threadedly connected to the first sliding member 14; when the first adjusting member 13 rotates, it can drive the first sliding member 14 to move along the axial direction of the first adjusting member 13. Thus, on the one hand, through the threaded connection, the rotation of the first adjusting member 13 can precisely control the movement distance of the first sliding member 14. Due to the precision of the thread, even a small rotation angle can cause a significant displacement change in the first sliding member 14, thereby achieving precise adjustment of the mechanical structure position. On the other hand, compared with other complex transmission mechanisms, this design achieves the drive of the first sliding member 14 through a simple threaded connection and rotation adjustment. This not only reduces the number of parts and manufacturing costs, but also improves the reliability and stability of the transmission mechanism. Furthermore, the threaded connection design allows the first adjusting member 13 and the first sliding member 14 to be tightly integrated, thereby reducing unnecessary space occupation. This is particularly important for applications with limited space, as it helps to improve the compactness and overall performance of the mechanical structure. Moreover, the threaded connection design makes the rotation of the first adjusting member 13 and the movement of the first sliding member 14 more intuitive and easier to operate, providing users with convenient maintenance and adjustment methods, enabling the mechanical structure to maintain optimal performance during long-term use.

[0044] like Figure 2As shown, preferably, in this embodiment, the first base 11 has a mounting cavity 112, and the first sliding member 14 includes a screw block 143 and a sliding block 144. The sliding block 144 is arranged laterally and slidably disposed on the first base 11. A guide groove 141 and a drive groove 142 are disposed on the sliding block 144. The screw block 143 is vertically connected to the sliding block 144 and extends into the mounting cavity 112. The first adjusting member 13 is threadedly connected to the screw block 143. In this way, by dividing the first sliding member 14 into two parts, the screw block 143 and the sliding block 144, and cleverly utilizing the mounting cavity 112 for layout, the entire mechanical structure is more compact and stable. Furthermore, the lateral arrangement of the sliding block 144 and the vertical arrangement of the screw block 143 together constitute a stable support structure, enhancing the overall stability of the mechanical structure.

[0045] like Figure 2 and Figure 3 As shown, specifically, the first base 11 is provided with a connecting hole 115, and the rotating shaft 121 is rotatably connected to the connecting hole 115. More specifically, the first rotating member 12 and the first base 11 are distributed vertically, and the sliding block 144 is disposed between the first rotating member 12 and the first base 11.

[0046] like Figure 2 and Figure 3 As shown, preferably, in this embodiment, the length of the sliding block 144 in the second direction exceeds the length of the screw block 143 in the second direction. Thus, the extended design of the sliding block 144 in the second direction provides sufficient space for the guide groove 141 and the drive groove 142 to be arranged on the sliding block 144, so that the guide groove 141 and the drive groove 142 can be arranged more flexibly on the sliding block 144. This not only ensures that the guide groove 141 and the drive groove 142 can be accurately aligned and cooperate with the corresponding transmission components, but also improves the overall accuracy and reliability of the mechanical structure.

[0047] like Figure 2 and Figure 3 As shown, preferably, in this embodiment, the screw block 143 is provided with a screw hole 1431, the first adjusting member 13 is threadedly connected to the screw hole 1431, and the sliding block 144 is provided with a clearance groove 1441, which is opposite to and communicates with the screw hole 1431. Thus, the screw hole 1431 allows the first adjusting member 13 to form a stable and precise threaded connection with the screw block 143. This connection method is not only robust and reliable but also easy to adjust and control. By rotating the first adjusting member 13, the position of the sliding block 144 can be easily adjusted, achieving precise transmission and displacement control. Furthermore, the clearance groove 1441 further optimizes the internal layout of the mechanical structure. It not only avoids interference between the sliding block 144 and the first adjusting member 13 but also makes the mechanical structure more compact and neat. This design helps reduce the overall volume and weight of the mechanical structure and improves space utilization.

[0048] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the first base 11 has a mounting sidewall opposite to the screw block 143. The mounting sidewall is provided with a rotating hole 114. The first adjusting member 13 has a threaded section 131 and a rotating section 132. The threaded section 131 is threadedly connected to the screw hole 1431. The rotating section 132 is rotatably connected to the rotating hole 114. Both ends of the rotating section 132 are provided with a limiting wall 133. The two limiting walls 133 are clamped on both sides of the mounting sidewall to restrict the axial movement of the rotating section 132.

[0049] like Figure 4 and Figure 5 As shown, this embodiment also provides a pulley mechanism, including the anti-sway component 1 as described above, and an anti-jump component 2. The anti-jump component 2 includes a second base 21, a second rotating member 22, a second adjusting member 23, and an anti-jump wheel body 24. The second rotating member 22 is rotatably disposed on the second base 21, and the anti-jump wheel body 24 is disposed on the second rotating member 22. The second adjusting member 23 and the second rotating member 22 are connected by a transmission. Under the drive of the second adjusting member 23, the second rotating member 22 can rotate up and down relative to the second base 21. The first base 11 is provided with a first locking structure 111, and the second base 21 is provided with a second locking structure 211. The first locking structure 111 and the second locking structure 211 are locked together to connect the first base 11 and the second base 21. Thus, firstly, the first seat 11 is specifically designed for the anti-sway wheel body 15 and its supporting components, while the second seat 21 is specifically designed for the anti-jump wheel body 24 and its supporting components. This design significantly reduces the length and volume of the first seat 11 and the second seat 21, thereby improving the effective utilization of space. Secondly, through the ingenious combination of the first snap-fit ​​structure 111 and the second snap-fit ​​structure 211, the two seats are tightly connected. This snap-fit ​​method not only occupies minimal space and does not increase the main body size of the two seats, but also ensures the stability of the connection while maintaining a compact volume, thereby improving the overall stability and reliability of the components. Furthermore, the design of the snap-fit ​​structure also gives... The ease of disassembly and replacement of the first seat 11 and the second seat 21 greatly enhances the flexibility of the design and the convenience of maintenance. At the same time, the independent design of the anti-sway structure and the anti-jump component 2 allows each component to be produced and assembled separately, simplifying the production process. More importantly, the anti-sway wheel body 15 and the anti-jump wheel body 24 are respectively placed on different seats, each independently performing its function, effectively avoiding mutual interference. In addition, since the size of the first seat 11 and the second seat 21 has been reduced, the design of the sliding door has become more flexible and diverse. Designers can choose different sizes or shapes of seats according to actual needs to meet diverse design requirements.

[0050] Preferably, in this embodiment, the first snap-fit ​​structure 111 is disposed at the end of the first base 11, and the second snap-fit ​​structure 211 is disposed at the end of the second base 21. Thus, on the one hand, by configuring the snap-fit ​​structure at the end of the base, additional connecting components can be avoided in the main body of the base, thereby ensuring that the compactness and sophistication of the base design are maximized. This design allows the base to function more efficiently within a limited space, improving space utilization. On the other hand, placing the snap-fit ​​structure at the end of the base makes the connection process between the first base 11 and the second base 21 exceptionally simple. The operator only needs to precisely align the ends of the two bases and apply appropriate force to complete the snap-fit ​​operation. This intuitive and efficient connection method not only significantly improves assembly speed but also reduces reliance on the operator's professional skills, making the entire installation process smoother and easier to manage.

[0051] Preferably, in this embodiment, one of the first snap-fit ​​structure 111 and the second snap-fit ​​structure 211 has a snap hook, and the other has a snap groove. The choice can be made according to actual needs, and no single limitation is made here.

[0052] like Figure 5 As shown, preferably, in this embodiment, the second adjusting member 23 is arranged laterally, and the anti-jump component 2 also includes a second sliding member. The second adjusting member 23 is rotatably connected to the second seat 21 and screwed to the second sliding member. The second sliding member and the second rotating member 22 are connected in a transmission manner. When the second adjusting member 23 rotates, the second sliding member slides along the axial direction of the second adjusting member 23 to drive the second rotating member 22 to rotate. The first seat 11 is provided with a laterally extending operating groove 113, which is arranged opposite to the second adjusting member 23. Thus, on the one hand, the second adjusting member 23 is arranged laterally and threadedly connected to the second sliding member. This design allows the rotation of the second adjusting member 23 to be converted into the linear sliding of the second sliding member. The sliding of the second sliding member then drives the second connecting member to rotate up and down relative to the second seat 21, achieving precise adjustment of the position of the anti-jump wheel body 24. This fine adjustment mechanism ensures the stability and reliability of the anti-jump component 2 under different usage scenarios. On the other hand, the operating groove 113 extends laterally and is arranged opposite to the second adjusting member 23, providing the user with an intuitive and easily accessible adjustment interface. Operating tools (such as wrenches, screwdrivers, etc.) can contact the second adjusting member 23 through the operating groove 113. The user can directly rotate the second adjusting member 23 through the operating groove 113, thereby driving the second sliding member to slide, and then driving the second connecting member to rotate, thereby achieving position adjustment of the anti-jump wheel body 24. This design makes the adjustment process simpler and more intuitive, improving the user experience.

[0053] Specifically, in this embodiment, the first rotating member 12 rotates left and right so that the two anti-sway wheel bodies 15 abut against the left and right side walls of the track groove respectively, thereby achieving the purpose of preventing the door and window sash from swaying. The second rotating member 22 rotates up and down so that the anti-jump wheel body 24 abuts against the top side wall of the track, thereby achieving the purpose of preventing the door and window sash from jumping.

[0054] In summary, the anti-sway component 1 and the pulley mechanism including it disclosed in this utility model can bring at least the following beneficial technical effects:

[0055] 1) By changing the arrangement direction of the drive groove 142 and the guide groove 141, the length of the first sliding member 14 was successfully reduced, and the entire anti-sway assembly 1 can be made more compact and lightweight, suitable for the needs of more miniaturized doors.

[0056] 2) The shorter drive slot 142 design facilitates the formation of an effective transmission connection between the drive slot 142 and the transmission block 122. Furthermore, while maintaining the same transmission performance, the shorter drive slot 142 helps to improve the compactness of the mechanical structure.

[0057] 3) The extension design of the sliding block 144 in the second direction provides sufficient space for the guide groove 141 and the drive groove 142 to be set on the sliding block 144, so that the guide groove 141 and the drive groove 142 can be arranged more flexibly on the sliding block 144. This not only ensures that the guide groove 141 and the drive groove 142 can be accurately aligned and cooperate with the corresponding transmission components, but also improves the overall precision and reliability of the mechanical structure.

[0058] 4) The first seat 11 is designed specifically for the anti-sway wheel body 15 and its supporting components, while the second seat 21 is designed specifically for the anti-jump wheel body 24 and its supporting components. This design allows the length and volume of the first seat 11 and the second seat 21 to be significantly reduced, thereby improving the effective utilization of space.

[0059] 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.
