Description

Technical Field

[0001] This utility model relates to the field of door and window hardware accessories, and in particular to a multifunctional upper wheel assembly. Background Technology

[0002] When a sliding door slides, it may sway left and right and bounce up and down. To solve these problems, anti-sway wheels and anti-jump wheels can be installed in the upper track. Furthermore, to reduce costs and improve space utilization, Chinese Patent Publication No. CN210977017U discloses a composite structure for anti-sway and anti-jump upper wheels in sliding doors and windows. This structure includes a base, with a base connecting a fixed plate elongated hole, a base connecting a fixed plate circular hole, and a first base connecting top wheel hole sequentially formed on the top of the base. Four sets of bearing wheel fixing plates forming a linkage mechanism are installed on the base at the top of the base connecting the fixed plate elongated hole. The bearing wheel fixing plates have a first fixing plate circular hole and a second fixing plate circular hole at both ends, and also have a fixing plate misalignment circular hole. Bearing wheel fixing rivets are installed at the base connecting the fixed plate elongated hole, and the bearing wheel fixing rivets pass through the second fixing plate circular hole. A bearing wheel is installed at the top of the bearing wheel fixing rivet, and the fixing plate misalignment rivets pass through the bearing wheel fixing plate. The base has an adjustment plate at its bottom, with an elongated hole and a round hole. A main body connecting rivet passes through the round hole of the adjustment plate, the elongated hole of the base connecting fixing plate, and the round hole of the first fixing plate. The elongated hole of the adjustment plate, the round hole of the base connecting fixing plate, and the round hole of the first fixing plate are also pierced by the main body connecting rivet. A fixing plate washer is fitted on the main body connecting rivet between the bearing wheel fixing plate and the base. A width adjusting screw is fixed to one side of the bottom of the adjustment plate by a width adjusting screw limit card. The width adjusting screw is threadedly connected to one end of the adjustment plate. A top wheel fixing screw is provided at the top wheel connecting hole of the first base. An elastic top wheel assembly is fixed to one side of the top of the base by the top wheel fixing screw. A top wheel frame is movably connected to the elastic top wheel assembly by a pin. The top wheel body is installed on the top of the top wheel frame. An elastic top wheel adjusting screw is fixed to one side of the elastic top wheel assembly. An adjusting block is movably connected to the top wheel frame by a pin. One end of the elastic top wheel adjusting screw is threadedly connected to the adjusting block.

[0003] However, the aforementioned composite structure requires the bearing wheel (i.e., the anti-sway wheel), the top wheel body (i.e., the anti-jump wheel), and related components to be installed on the base. The base needs to be compatible with the anti-sway wheel, the anti-jump wheel, and all related components. This results in a larger base length and volume, which limits the design flexibility and space utilization of the sliding door. Utility Model Content

[0030] 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.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figures 1 to 5This embodiment discloses a multifunctional upper wheel assembly, including an anti-sway structure 1 and an anti-jump structure 2. The anti-sway structure 1 includes a first seat 11, a first connector 12, and two anti-sway wheel bodies 13. The first connector 12 is disposed on the first seat 11, and the two anti-sway wheel bodies 13 are respectively disposed at both ends of the first connector 12. The two anti-sway wheel bodies 13 are respectively used to abut against the side walls of the track groove. The anti-jump structure 2 includes a second seat 21, a second connector 22, and an anti-jump wheel body 23. The second connector 22 is disposed on the second seat 21, and the anti-jump wheel body 23 is disposed on the second connector 22. The anti-jump wheel body 23 is used to abut against the top wall of the track groove. The first seat 11 is provided with a first locking structure 111, and the second seat 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 seat 11 and the second seat 21.

[0033] The multifunctional upper wheel assembly disclosed in this embodiment has several advantages. Firstly, the first seat 11 is only compatible with the anti-sway wheel body 13 and its related components, and the second seat 21 is only compatible with the anti-jump wheel body 23 and its related components. Therefore, the length and volume of both the first seat 11 and the second seat 21 can be significantly reduced, improving space utilization. Secondly, the first seat 11 and the second seat 21 are connected by a first snap-fit ​​structure 111 and a second snap-fit ​​structure 211. These snap-fit ​​structures occupy minimal space, do not occupy the main space of the two seats, and do not additionally increase their length or volume. Furthermore, this design allows for a robust connection between the two seats while maintaining a compact size, ensuring the assembly's stability. The overall stability and reliability are improved; on the other hand, the snap-fit ​​structure allows the first seat 11 and the second seat 21 to be easily disassembled and replaced, further improving the design flexibility and maintainability; furthermore, the separate design of the anti-sway structure 1 and the anti-jump structure 2 allows each component to be produced and assembled independently, simplifying the production process. Moreover, the anti-sway wheel body 13 and the anti-jump wheel body 23 are respectively set on different seats, each undertaking different functions, avoiding mutual interference; in addition, due to the reduced size of the first seat 11 and the second seat 21, the design of the sliding door is more flexible, and different sizes or shapes of seats can be selected according to actual needs to meet different design requirements.

[0034] like Figure 1 and Figure 2As shown, preferably, in this embodiment, the first snap-fit ​​structure 111 is disposed at the end of the first seat 11, and the second snap-fit ​​structure 211 is disposed at the end of the second seat 21. Thus, on the one hand, by placing the snap-fit ​​structures at the ends of the two seats, additional connecting structures are avoided in the main body of the two seats, thereby maximizing the compactness and small size of the seats. This design allows the seats to function more efficiently within a limited space, improving space utilization. On the other hand, placing the snap-fit ​​structures at the ends of the seats makes it easier to connect the first seat 11 and the second seat 21. The operator only needs to align the ends of the two seats and apply appropriate force to complete the snap-fit ​​process. This convenient connection method not only improves assembly efficiency but also reduces the skill requirements for the operator.

[0035] like Figure 2 and Figure 6 As shown, specifically in this embodiment, the anti-jump structure 2 further includes a second adjusting member 24 arranged laterally. The second adjusting member 24 is rotatably disposed on the second seat 21 and is connected to the second connecting member 22 in a transmission manner. The second connecting member 22 is hinged to the second seat 21. When the second adjusting member 24 rotates, the second connecting member 22 can rotate up and down relative to the second seat 21 under the drive of the second adjusting member 24.

[0036] like Figure 2 and Figure 6 As shown, preferably, in this embodiment, the second adjusting member 24 has an operating end 241, which protrudes from the outer side wall of the second seat 21, and the operating end 241 and the second snap-fit ​​structure 211 are located at the same end of the second seat 21; more preferably, during installation, the second seat 21 can rotate relative to the first seat 11 between a pre-installation position and a fixed position; as shown Figure 6 As shown, when the second seat 21 is in the pre-installation position, the second seat 21 can move horizontally to allow the operating end 241 to penetrate into the first seat 11. After the operating end 241 penetrates into the first seat 11, the first locking structure 111 and the second locking structure 211 are vertically aligned. At this time, the second seat 21 can be rotated to a fixed position to lock the second locking structure 211 and the first locking structure 111 together. For details on the state in which the second seat 21 can be rotated to a fixed position, please refer to [reference needed]. Figure 2 This setup has the following advantages:

[0037] First, the rotational setting of the second adjusting member 24 and the transmission connection design with the second connecting member 22 enable the second connecting member 22 to rotate up and down relative to the second base 21. This design not only increases the flexibility of the structure, but also greatly facilitates the adjustment during the installation process. By simply rotating the operating end 241 of the second adjusting member 24, the position of the second connecting member 22 can be precisely adjusted without the need for complicated tools or additional steps.

[0038] Secondly, the operating end 241 protrudes from the outer side wall of the second base 21 and is located at the same end as the second snap-fit ​​structure 211. This layout allows the operator to intuitively and quickly find and operate the adjustment component during installation. The location of the operating end 241 makes it easy to access, and it can be easily operated even in a limited space, thereby improving installation efficiency.

[0039] Secondly, it is understandable that in order to reduce the overall length, the lengths of both the first base 11 and the second base 21 are relatively small. Due to structural limitations, the installation of both the first base 11 and the second base 21 is somewhat difficult. However, the design of the second base 21, which can rotate relative to the first base 11 between the pre-installation position and the fixed position, provides greater flexibility for the installation process. In the pre-installation position, the second base 21 can move horizontally, allowing the operating end 241 to smoothly penetrate into the first base 11. This step simplifies the installation process and avoids installation difficulties caused by structural limitations. Finally, after the operating end 241 is inserted into the first base 11, the first snap-fit ​​structure 111 and the second snap-fit ​​structure 211 are positioned vertically opposite each other. At this point, by simply rotating the second base 21 to the fixed position, precise snap-fit ​​fixing can be achieved. This design not only ensures the stability and reliability of the structure but also reduces the risk of errors during the installation process.

[0040] More specifically, during installation, the second seat 21 rotates about the overall length of the multi-functional upper wheel assembly.

[0041] like Figure 1 , Figure 2 and Figure 6As shown, preferably, in this embodiment, the anti-jump structure 2 further includes a second sliding member (not labeled), the second adjusting member 24 is screwed to the second sliding member, the second sliding member and the second connecting member 22 are connected in a transmission manner, when the second adjusting member 24 rotates, the second sliding member slides along the axial direction of the second adjusting member 24 to drive the second connecting member 22 to rotate; the first base 11 is provided with a laterally extending operating groove 112, and the operating end 241 is located in the operating groove 112. Thus, on the one hand, the second adjusting member 24 is arranged laterally and threadedly connected to the second sliding member. This design allows the rotation of the second adjusting member 24 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 22 to rotate up and down relative to the second seat 21, realizing the precise adjustment of the position of the anti-jump wheel body 23. This fine adjustment mechanism ensures the stability and reliability of the anti-jump structure 2 under different usage scenarios. On the other hand, the operating end 241 is located in the laterally extending operating groove 112, providing the user with an intuitive and easily accessible adjustment interface. Operating tools (such as wrenches, screwdrivers, etc.) can contact the operating end 241 of the second adjusting member 24 through the operating groove 112. The user can directly rotate the operating end 241 through the operating groove 112, thereby driving the second sliding member to slide, and then driving the second connecting member 22 to rotate, realizing the position adjustment of the anti-jump wheel body 23. This design makes the adjustment process simpler and more intuitive, improving the user experience.

[0042] like Figure 2 , Figure 3 and Figure 6 As shown, more preferably, in this embodiment, a first support platform 1121 is provided in the operating groove 112, which supports the operating end 241. This arrangement serves two purposes: firstly, the first support platform 1121 provides a stable support surface for the operating end 241, effectively preventing wobbling or displacement of the operating end 241 during adjustment. This stability ensures the precision and consistency of the adjustment action, improving the overall accuracy and reliability of the operation. Secondly, the first support platform 1121 in the operating groove 112 makes operation smoother and more comfortable. Users can feel a more stable support when adjusting with the operating tool, reducing instability during operation and thus improving the overall user experience.

[0043] like Figure 2 , Figure 3 and Figure 4As shown, specifically in this embodiment, the first support platform 1121 is located at the end of the operating groove 112 near the operating end 241. More preferably, a second support platform 1122 is provided at the end of the operating groove 112 away from the operating end 241. The second support platform 1122 is used to support the operating tool. With this arrangement, the second support platform 1122 is located at the end of the operating groove 112 away from the operating end 241 to support the operating tool. This design provides a stable support surface for the operating tool, further enhancing the stability of the entire operation process. Furthermore, the first support platform 1121 and the second support platform 1122 provide dual support, making the operation more reliable, improving the accuracy of adjustment, and enabling users to complete adjustment tasks more easily and accurately, thus enhancing the overall operating experience.

[0044] like Figure 6 As shown, preferably, in this embodiment, the first snap-fit ​​structure 111 protrudes from one end of the first base 11, and an installation opening 117 is formed between one end of the first base 11 and the first snap-fit ​​structure 111. When the second base 21 is in the pre-installation position, the second base 21 can move horizontally to connect one end of the second base 21 into the installation opening 117. This configuration, on the one hand, greatly simplifies the installation process by having the first snap-fit ​​structure 111 protrude from one end of the first base 11 and form the installation opening 117 between them. In the pre-installation position, the second base 21 can easily move horizontally until one end aligns with and connects to the installation opening 117. This installation method avoids complex positioning and adjustment steps, improving installation efficiency. On the other hand, the installation opening 117 provides a clear reference point for the second base 21 during horizontal movement, ensuring installation accuracy. Once one end of the second base 21 enters the installation opening 117, it is easy to determine whether it has reached the correct installation position, which helps reduce errors during installation.

[0045] like Figure 1 and Figure 2 As shown, preferably, in this embodiment, the first locking structure 111 includes a first locking groove 1111 and a first locking block 1112, and the second locking structure 211 includes a second locking groove 2111 and a second locking block 2112; the first locking groove 1111 and the second locking block 2112 are locked together, and the first locking block 1112 and the second locking groove 2111 are locked together. Thus, the mutual locking of the first locking groove 1111 and the second locking block 2112, and the first locking block 1112 and the second locking groove 2111, forms an interlocking mechanism. This mechanism allows the first seat 11 and the second seat 21 to be tightly fixed together after connection, effectively preventing relative movement or loosening between them. This strong stability is crucial for ensuring the reliability of the multi-functional upper wheel assembly under external force or during long-term use.

[0046] It should be noted that in some other embodiments, the first snap-fit ​​structure 111 and the second snap-fit ​​structure 211 may be either a snap hook or a snap slot.

[0047] like Figure 3 , Figure 4 and Figure 5 As shown, preferably, in this embodiment, the anti-sway structure 1 further includes a first adjusting member 14, which is rotatably mounted on the first base 11 and connected to the first connecting member 12. The first connecting member 12 is hinged to the first base 11. When the first adjusting member 14 rotates, the first connecting member 12 can rotate left and right relative to the first base 11 under the drive of the first adjusting member 14. In this way, by rotating the first adjusting member 14, the position of the first connecting member 12 and the anti-sway wheel body 13 mounted thereon can be easily adjusted to adapt to track grooves of different widths or shapes. This flexible adjustability allows the multifunctional upper wheel assembly to be more widely used in various sliding doors or windows, improving its versatility and adaptability. Furthermore, the fact that the first connecting member 12 can rotate left and right means that the anti-sway wheel body 13 can fit more tightly against the two side walls of the track groove. This tight fit not only enhances the stability of the anti-sway wheel body 13 but also improves its anti-sway effect.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, specifically, in this embodiment, the anti-sway structure 1 further includes a first sliding member 15, which is slidably disposed on the first seat 11 along a first direction. The first connecting member 12 is hinged to the first seat 11 via a rotating shaft 122. The first adjusting member 14 is threadedly connected to the first sliding member 15. A first slotted block engaging structure is provided between the first sliding member 15 and the first connecting member 12. When the first adjusting member 14 rotates to drive the first sliding member 15 to slide relative to the first seat 11, the first sliding member 15 can drive the first connecting member 12 to rotate left and right relative to the first seat 11 through the first slotted block engaging structure. Thus, through the first slotted block engaging structure provided between the first sliding member 15 and the first connecting member 12, the sliding of the first sliding member 15 can be converted into the left and right rotation of the first connecting member 12 relative to the first seat 11, thereby realizing the precise adjustment of the position of the anti-sway wheel body 13.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, preferably, the first slider 15 is provided with a guide groove 151 extending along a first direction, and the rotating shaft 122 is located in the guide groove 151. The rotating shaft 122 and the guide groove 151 slide in each other to provide guidance for the movement of the first slider 15 and prevent the first slider 15 from deviating from the predetermined movement trajectory.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, preferably, in this embodiment, the first slot block engaging structure includes a driving slot 152 and a transmission block 121. The driving slot 152 is disposed on the first sliding member 15, and the transmission block 121 protrudes from the first connecting member 12. The transmission block 121 is drivenly connected to the driving slot 152. The guide slot 151 and the driving slot 152 extend in the same plane. The extension direction of the driving slot 152 is inclined to or perpendicular to the first direction. The driving slot 152 and the guide slot 151 are arranged sequentially in the second direction. The second direction and the first direction are located in the same plane and are perpendicular to each other. When the first adjusting member 14 rotates to drive the first sliding member 15 to slide relative to the first seat 11, under the drive of the first sliding member 15, the guide slot 151 moves along the first direction and drives the transmission block 121 to rotate around the rotating shaft 122. Under the drive of the transmission block 121, the first rotating member rotates left and right relative to the first seat 11. Thus, by designing the guide groove 151 and the drive groove 152 to be arranged sequentially in the second direction, the extension of the anti-sway structure 1 in the overall length direction (that is, the first direction) can be reduced, and the limited space can be utilized to the maximum extent. This compact layout avoids the waste of space, and allows the anti-sway structure 1 to have a smaller size while maintaining its functionality.

[0051] It should be noted that in some other embodiments, the guide groove 151 and the drive groove 152 may also be arranged sequentially in the first direction. The choice can be made according to actual needs and is not limited here.

[0052] like Figure 1 and Figure 2 As shown, preferably, in this embodiment, the anti-jump structure 2 further includes a second adjusting member 24. The second adjusting member 24 is rotatably disposed on the second seat 21 and is drivenly connected to the second connecting member 22. The second connecting member 22 is hinged to the second seat 21. When the second adjusting member 24 rotates, the second connecting member 22 can rotate up and down relative to the second seat 21 under the drive of the second adjusting member 24. Thus, the second adjusting member 24 is rotatably disposed on the second seat 21 and is drivenly connected to the second connecting member 22. This design allows the second connecting member 22 to be easily driven to rotate up and down relative to the second seat 21 by rotating the second adjusting member 24. This flexible adjustability allows the anti-jump structure 2 to adapt to tracks of different heights or shapes, ensuring that the sliding door or window remains stable during sliding and effectively preventing jumping.

[0053] Specifically, in this embodiment, a second slot block engaging structure (not labeled) is provided between the second adjusting member 24 and the second connecting member 22. When the second adjusting member 24 rotates to drive the second sliding member to slide relative to the second seat 21, the second sliding member can drive the second connecting member 22 to rotate up and down relative to the second seat 21 through the second slot block engaging structure.

[0054] like Figure 1 , Figure 3 and Figure 5 As shown, specifically, in this embodiment, the multi-functional upper wheel assembly also includes a fastening screw 3; the side wall of the first seat 11 is provided with a pressing edge 115, and the first seat 11 is also provided with a positioning hole 116. The positioning hole 116 is inclined from the end wall of the first seat 11 toward the bottom wall of the first seat 11. The fastening screw 3 is embedded in the positioning hole 116, and the front end of the fastening screw 3 can extend from the positioning hole 116 to the bottom wall of the first seat 11.

[0055] Specifically, the upper frame of the door and window sash is provided with a fixing groove. The fixing groove has a fixing bottom surface and a fixing shoulder. The fixing shoulder and the fixing bottom surface are arranged opposite each other. The first seat 11 is set in the fixing groove. As the fastening screw 3 is screwed in, the fixing bottom surface generates a reaction force on the fastening screw 3, gradually pushing the first seat 11 up, so that the pressing edge 115 is pressed against the fixing shoulder, thereby fixing the first seat 11 in the fixing groove. Thus, on the one hand, by designing a multifunctional upper wheel assembly including a fastening screw 3, and specifically by embedding the fastening screw 3 into a positioning hole 116 that is inclined from the end wall of the first seat 11 towards the bottom wall, the front end of the fastening screw 3 can extend out of the positioning hole 116 and apply an upward force to the first seat 11 when tightening it. This design allows the first seat 11 to fit tightly with the fixing groove of the upper frame of the door and window sash. The pressing of the pressing edge 115 with the fixing shoulder greatly enhances the stability of the installation and ensures the stability and safety of the door and window sash. On the other hand, the inclined positioning hole 116 and the fastening screw 3 design allow the first seat 11 to be installed simply by tightening the fastening screw 3. The fastening screws 3 secure the first seat 11 to the fixing groove of different sizes and shapes, eliminating the need for additional tools or steps. This simplifies the installation process, improves efficiency, and reduces costs. Furthermore, the multi-functional upper wheel assembly is highly adaptable to various types and specifications of doors and windows, enhancing its versatility and market competitiveness. Finally, the fastening screws 3 firmly press the first seat 11 against the fixing shoulder, effectively reducing the gap between the first seat 11 and the fixing groove, thus improving the sealing performance of the doors and windows, preventing wind, rain, dust, and other external factors from entering the room, and enhancing the comfort and safety of the living environment.

[0056] like Figure 4 and Figure 5As shown, preferably, in this embodiment, the first base 11 includes a mounting base 113 and a fixing base 114. The fixing base 114 is used to fix to the upper frame of the door / window sash. The mounting base 113 is disposed on the fixing base 114. The first adjusting member 14 is rotatably disposed on the mounting base 113. The first sliding member 15 is slidably disposed on the mounting base 113. The first connecting member 12 is hinged to the mounting base 113. The mounting base 113 is provided with a third snap-fit ​​structure 1131, and the fixing base 114 is provided with a fourth snap-fit ​​structure 1141. The third snap-fit ​​structure 1131 and the fourth snap-fit ​​structure 1141 are snapped together to connect the mounting base 113 and the fixing base 114. Thus, on the one hand, the main function of the fixing seat 114 is to be firmly installed on the upper frame of the door and window sash. As the basic support part of the entire device, the design of the fixing seat 114 must ensure a tight fit and stable connection with the door and window sash frame to prevent loosening or displacement during use. On the other hand, the mounting seat 113 is a structure set on the fixing seat 114. It supports the installation and operation of the first adjusting member 14, the first sliding member 15, and the first connecting member 12. The design of the mounting seat 113 must consider the movement requirements of these components to ensure that they can work flexibly and stably within a predetermined range. Furthermore, this snap-fit ​​design of the mounting seat 113 and the fixing seat 114 not only simplifies the installation process but also makes the installation more secure. Mounting bracket 113 can be quickly and accurately fixed to mounting bracket 114, improving the stability and durability of the connection. Users can complete the assembly without complicated tools or professional skills, and it is also convenient for future maintenance and replacement. Finally, the third snap-fit ​​structure 1131 and the fourth snap-fit ​​structure 1141 usually adopt a snap-fit ​​or slot design without screws or nuts. This design avoids the need for a large number of fasteners in traditional connection methods, thereby reducing the number of parts and the complexity of the overall structure. Furthermore, since the snap-fit ​​structure can directly and tightly connect two parts together without the need for additional space to accommodate fasteners, a more compact layout can be achieved, which helps to reduce the overall size of the product, making it smaller and lighter.

[0057] More specifically, in this embodiment, the pressing edge 115 can be provided on the mounting base 113 or the fixing base 114, the positioning hole 116 needs to be opened on the bottom of the fixing base 114, and the first snap-fit ​​structure 111 can be provided on either the mounting base 113 or the fixing base 114, or they can be formed together on both the mounting base 113 and the fixing base 114.

[0058] like Figure 1As shown, specifically in this embodiment, the axis of the anti-sway wheel body 13 is arranged vertically, and the axis of the anti-jump wheel body 23 is arranged horizontally. Thus, on the one hand, the vertically oriented anti-sway wheel body 13 is mainly used to limit the swaying of the door / window sash during opening. Through the friction or damping effect generated by its rotation, it can effectively slow down the swaying speed of the door / window sash, preventing damage or safety hazards caused by excessive swaying. On the other hand, the horizontally oriented anti-jump wheel body 23 focuses on preventing the door / window sash from jumping in the vertical direction. Especially under strong winds or external forces, it can maintain the stable position of the door / window sash, preventing accidental opening or closing, and enhancing the sealing and safety of the door / window. Furthermore, the reasonable axis arrangement allows the anti-sway wheel body 13 and the anti-jump wheel body 23 to each perform their respective functions, jointly maintaining the stability and safety of the door / window. This not only improves the service life of the door / window but also provides users with a smoother and more stable door / window operation experience.

[0059] In summary, the multifunctional upper wheel assembly disclosed in this utility model can bring at least the following beneficial technical effects:

[0060] 1) The first seat 11 is only compatible with the anti-sway wheel body 13 and its related components, and the second seat 21 is only compatible with the anti-jump wheel body 23 and its related components. The length and volume of the first seat 11 and the second seat 21 can be greatly reduced, thus improving space utilization.

[0061] 2) The first base 11 and the second base 21 are connected by the first snap-fit ​​structure 111 and the second snap-fit ​​structure 211. The snap-fit ​​structure occupies less space, does not occupy the main space of the two bases, and does not increase the length and volume of the two bases. Moreover, this design allows the two bases to achieve a firm connection while maintaining a small size, ensuring the overall stability and reliability of the component.

[0062] 3) The separate design of anti-sway structure 1 and anti-jump structure 2 allows each component to be produced and assembled independently, simplifying the production process. Furthermore, the anti-sway wheel body 13 and the anti-jump wheel body 23 are respectively set on different seats, each undertaking different functions, thus avoiding mutual interference.

[0063] 4) The snap-fit ​​structure is set at the ends of the two seats, avoiding the need to add additional connecting structures to the main body of the two seats, thus maximizing the compactness and small size of the seats. This design allows the seats to function more efficiently in a limited space and improves space utilization.

[0064] 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.
