[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A lifting wheel includes: a main body having a lifting cavity and an adjusting hole that are interconnected within the main body; the lifting cavity being vertically oriented; and the axial direction of the adjusting hole being inclined relative to the axial direction of the lifting cavity; a wheel body disposed within the main body; a lifting member slidably disposed within the lifting cavity; and an adjusting member disposed within the adjusting hole, extending partially into the interior of the lifting cavity and abutting against the lifting member; the adjusting member being movable along the axial direction of the adjusting hole to adjust the height of the lifting member; wherein, an anti-detachment structure is provided inside / at the end of the adjusting hole; when the adjusting member moves along the axial direction of the adjusting hole to its lowest position, the anti-detachment structure contacts the adjusting member to restrict the downward movement of the adjusting member.

[0007] According to some embodiments of the present invention, the adjustment hole extends obliquely from the first side wall of the main body to the hoisting cavity, and the anti-detachment structure is an anti-detachment protrusion, which is disposed on the first side wall.

[0008] According to some embodiments of the present invention, multiple anti-detachment protrusions are provided, and the multiple anti-detachment protrusions are arranged around the end of the hoisting cavity.

[0009] According to some embodiments of the present invention, the adjusting member has an abutting end and an operating end. The abutting end extends into the interior of the hoisting cavity and abuts against the hoisting member. The operating end is disposed relatively away from the hoisting cavity. Applying force to the operating end can cause the adjusting member to move axially along the adjusting hole. When the operating end moves axially along the adjusting hole to the lowest position, the anti-detachment structure contacts the operating end to restrict the downward movement of the operating end.

[0010] According to some embodiments of the present invention, the wheel body is provided in two sets, and the two sets of wheel bodies are spaced apart on the main body; the hanging wheel also includes a functional component; the main body is provided with an intermediate mounting position, which is located between the two sets of wheel bodies, and the intermediate mounting position is used to install the functional component.

[0011] According to some embodiments of the present invention, the hoisting cavity has an anti-sway hole, the hoisting component has an anti-sway part, the anti-sway part is slidably connected to the anti-sway hole, and the anti-sway hole gradually decreases in the length direction of the main body.

[0012] According to some embodiments of the present invention, the lifting component is provided with an anti-detachment edge on the side facing the adjustment hole; the adjustment component has an annular groove, and the anti-detachment edge is disposed in the annular groove.

[0013] According to some embodiments of the present invention, the adjusting member is threadedly connected to the adjusting hole.

[0014] In addition, this utility model also provides a hanging wheel installation structure, including the hanging wheel as described above, and also including a connector and a fixing member. The connector is used to connect the door leaf. The lower end of the hanging member and the connector are embedded and connected. The fixing member is snapped between the lower end of the hanging member and the connector to fix the hanging member and the connector.

[0015] According to some embodiments of the present invention, the lower end of the hoisting component is provided with a horizontally extending locking block, the connecting component is provided with a locking groove, the locking block is embedded in the locking groove, the locking groove has an upper top wall, the upper top wall is located above the locking block, the fixing component is snapped into the locking groove, and the upper top wall and the fixing component are clamped and fixed to the locking block from above and below.

[0016] In summary, the hanging wheel and the hanging wheel mounting structure including the present invention have at least the following technical effects:

[0017] By incorporating an anti-detachment structure inside / at the adjustment hole, the stroke of the adjusting component is limited, thereby limiting the stroke of the lifting component. This prevents the adjusting and lifting components from falling off the main body. Furthermore, since there is no need to install stroke-limiting components on the main body structure between adjacent sets of wheels, ample space is reserved on the main body for installing other functional components, such as buffer devices, locking devices, and lubrication devices, to meet the diverse needs of different users. At the same time, wheel installation is easier; simply install the wheels in the designated positions on the main body without considering the space limitations imposed by stroke-limiting components.

Detailed Implementation

[0029] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[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 7This utility model discloses a hanging wheel, including a main body 1, a wheel body 2, a lifting component 3, and an adjusting component 4. The lifting component 3 is used to connect with a door or window sash. The main body 1 is provided with a lifting cavity 11 and an adjusting hole 12 that are interconnected. The lifting cavity 11 is vertically arranged, and the axial direction of the adjusting hole 12 is inclined relative to the axial direction of the lifting cavity 11. The wheel body 2 is disposed on the main body 1. The lifting component 3 is slidably disposed in the lifting cavity 11. The adjusting component 4 is disposed in the adjusting hole 12 and partially extends into the interior of the lifting cavity 11 and abuts against the lifting component 3. The adjusting component 4 can move along the axial direction of the adjusting hole 12 to adjust the height of the lifting component 3. The adjusting hole 12 is provided with an anti-detachment structure 13 inside / at the end. When the adjusting component 4 moves along the axial direction of the adjusting hole 12 to the lowest position, the anti-detachment structure 13 contacts the adjusting component 4 to restrict the downward movement of the adjusting component 4.

[0034] like Figure 4 and Figure 5 As shown, specifically, when it is necessary to increase the height of the lifting component 3, the operator operates the adjusting component 4, causing it to tilt upward within the adjusting hole 12. During this movement, the contact point between the adjusting component 4 and the lifting component 3 gradually rises, thus pushing against the lifting component 3 and causing it to slide upward within the lifting cavity 11, thereby increasing the height of the lifting component 3. Conversely, when it is necessary to decrease the height of the lifting component 3, the operator operates the adjusting component 4, causing it to tilt downward. Under the influence of gravity, the lifting component 3 slides downward relative to the lifting cavity 11, thereby decreasing its height.

[0035] The lifting wheel provided in this embodiment limits the stroke of the adjusting member 4 by providing an anti-detachment structure 13 inside / at the end of the adjusting hole 12, thereby limiting the stroke of the lifting member 3. This prevents the adjusting member 4 and the lifting member 3 from falling off the main body 1. Furthermore, since there is no need to install stroke limiting components on the structure of the main body 1 between two adjacent sets of wheel bodies 2, sufficient space is reserved on the main body 1 for installing other functional components 5, such as buffer devices, locking devices, and oiling devices, to meet the diverse needs of different users. At the same time, the installation of the wheel body 2 is also easier; it can be installed at the designated position on the main body 1 without considering the limitation of installation space by the stroke limiting components.

[0036] It is understandable that during the actual adjustment process, the adjusting member 4 and the lifting member 3 are not easily dislodged from the top of the main body 1. Relatively speaking, limiting the downward travel of the adjusting member 4 and the lifting member 3 is more important than limiting the upward travel. Furthermore, it should be noted that in some other embodiments, the anti-detachment structure 13 can be divided into two groups. One group of anti-detachment structures 13 is used to limit the downward travel of the adjusting member 4 and the lifting member 3, and the other group of anti-detachment structures 13 is used to limit the upward travel of the adjusting member 4 and the lifting member 3. That is to say, when the adjusting member 4 moves to the lowest position along the axial direction of the adjusting hole 12, one group of anti-detachment structures 13 contacts the adjusting member 4 to limit the downward movement of the adjusting member 4. When the adjusting member 4 moves to the highest position along the axial direction of the adjusting hole 12, the other group of anti-detachment structures 13 contacts the adjusting member 4 to limit the upward movement of the adjusting member 4.

[0037] Specifically, the lifting component 3 is designed with a suitable shape and size to fit tightly with the lifting cavity 11 and achieve stable sliding. The adjusting component 4 is located within the adjusting hole 12, with part of its structure extending into the lifting cavity 11 and abutting against the lifting component 3. The adjusting component 4 can engage with the adjusting hole 12 via threaded connection, snap-fit, or other means, allowing it to move axially along the adjusting hole 12. When the height of the lifting component 3 needs to be adjusted, simply rotate or push the adjusting component 4 to move it within the adjusting hole 12, thereby changing the contact position between the adjusting component 4 and the lifting component 3, and thus adjusting the height of the lifting component 3.

[0038] like Figure 4 , Figure 5 and Figure 7 As shown, preferably, in this embodiment, the adjusting member 4 is threadedly connected to the adjusting hole 12. According to the principle of screw transmission, the adjusting member 4 can move within the adjusting hole 12, thereby causing the lifting member 3 to move up and down relative to the lifting cavity 11, which in turn drives the door leaf to move up and down. Furthermore, due to the self-locking effect of the thread, the adjusting member 4 is not easy to loosen when subjected to external force, thus playing an anti-loosening role.

[0039] like Figure 1 and Figure 2 As shown, specifically, in this embodiment, two sets of wheel bodies 2 are provided, and the two sets of wheel bodies 2 are spaced apart on the main body 1; the hanging wheel also includes a functional component 5; more specifically, the main body 1 is provided with an intermediate mounting position 15, which is located between the two sets of wheel bodies 2, and the intermediate mounting position 15 is used to install the functional component 5. Optionally, in this embodiment, the functional component 5 is an oil tank for supplying oil to the upper body of the wheel body 2.

[0040] like Figure 1 , Figure 4 , Figure 5 and Figure 8As shown, specifically, in this embodiment, the adjustment hole 12 extends obliquely from the first side wall 14 of the main body 1 to the hoisting cavity 11. Preferably, the anti-detachment structure 13 is an anti-detachment protrusion 131. The anti-detachment protrusion 131 is disposed on the first side wall 14. When the adjustment member 4 moves to the lowest position along the axial direction of the adjustment hole 12, the anti-detachment protrusion 131 and the adjustment member 4 come into contact, forming an effective blocking structure. This design can effectively limit the adjustment member 4 from continuing to move downward, thereby preventing the adjustment member 4 and the hoisting member 3 from detaching from the main body 1.

[0041] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, more preferably, in this embodiment, multiple anti-detachment protrusions 131 are provided, and the multiple anti-detachment protrusions 131 are arranged around the end of the hoisting cavity 11. In this way, when the adjusting member 4 moves to the lowest position along the axial direction of the adjusting hole 12, the multiple anti-detachment protrusions 131 arranged around the adjusting member 4 form multi-point contact and constraint, thereby increasing the restrictive force on the adjusting member 4.

[0042] It should be noted that in some other embodiments, the anti-detachment structure 13 may also be, but is not limited to, an anti-detachment retaining ring or an anti-detachment elastic arm, etc., which can be selected according to actual needs, and is not limited to one specific type here.

[0043] like Figure 4 , Figure 5 and Figure 7 As shown, specifically, in this embodiment, the adjusting member 4 has an abutment end 41 and an operating end 42. The abutment end 41 extends into the interior of the lifting cavity 11 and abuts against the lifting member 3. The operating end 42 is disposed relatively away from the lifting cavity 11. Applying force to the operating end 42 can cause the adjusting member 4 to move axially along the adjusting hole 12. Preferably, in this embodiment, when the operating end 42 moves axially along the adjusting hole 12 to the lowest position, the anti-detachment structure 13 contacts the operating end 42 to limit the downward movement of the operating end 42. Thus, on the one hand, the abutting end 41 of the adjusting member 4 extends into the hoisting cavity 11 and abuts against the hoisting member 3. By applying external force to the operating end 42 to move the adjusting member 4 axially along the adjusting hole 12, the position of the hoisting member 3 in the hoisting cavity 11 can be changed directly and accurately. This design makes the adjustment of the hoisting member 3 highly accurate, which can meet the needs of fine adjustment of the position of the hoisting member 3 and ensure that the hoisting member 3 is in the optimal working position. In addition, the operating end 42 is set relatively far away from the hoisting cavity 11, which also provides sufficient operating space for the operator. On the other hand, when the operating end 42 moves to the lowest position along the axial direction of the adjusting hole 12, the anti-detachment protrusion 131 contacts the operating end 42, forming an effective block, which restricts the operating end 42 from continuing to move downward, thereby preventing the adjusting member 4 from falling out of the adjusting hole 12.

[0044] like Figure 4 , Figure 5 and Figure 6 As shown, specifically in this embodiment, the lifting member 3 has an abutting inclined surface 36, which is perpendicular to the axial direction of the adjusting hole 12. With this configuration, since the axial direction of the adjusting hole 12 is inclined relative to the axial direction of the lifting hole, this means that the adjusting member 4 moves along a direction inclined to the axial direction of the lifting hole. To make the adjusting member 4 and the lifting member 3 abut more stably, an abutting inclined surface 36 perpendicular to the axial direction of the adjusting hole 12 is formed within the lifting member 3. Therefore, the abutting inclined surface 36 forms a perpendicular abutting structure with the adjusting member 4, resulting in a more stable structure under stress, thereby improving the overall structural stability. More specifically, the aforementioned abutting end 41 abuts against the abutting inclined surface 36.

[0045] like Figure 4 , Figure 5 and Figure 6 As shown, specifically in this embodiment, the lifting member 3 has a clearance slope 33, which is parallel to the axial direction of the adjusting hole 12 and connected to the abutment slope 36. With this configuration, since the adjusting member 4 will move along a direction inclined to the axial direction of the lifting hole, to avoid interference between the adjusting member 4 and the lifting member 3 during movement, a clearance slope 33 parallel to the axial direction of the adjusting hole 12 is formed within the lifting member 3. This effectively avoids interference and improves overall movement safety.

[0046] like Figure 2 and Figure 6 As shown, preferably, in this embodiment, the hoisting cavity 11 has an anti-sway hole 111, and the hoisting component 3 has an anti-sway part 31. The anti-sway part 31 is slidably connected to the anti-sway hole 111. The anti-sway hole 111 gradually decreases in the length direction of the main body 1. In this way, the gradually decreasing anti-sway hole 111 will form a constraint force on the anti-sway part 31. When the hoisting component 3 is disturbed by the outside and has a tendency to swing in the thickness direction of the main body 1, the side wall of the anti-sway hole 111 will fit tightly with the anti-sway part 31. Through this tight contact and constraint, the swing of the hoisting component 3 in the thickness direction of the main body 1 is effectively prevented.

[0047] like Figure 2 and Figure 6 As shown, specifically, the projection of the anti-sway hole 111 onto the horizontal plane is trapezoidal.

[0048] like Figure 2 and Figure 6 As shown, preferably, in this embodiment, the hoisting cavity 11 also has a guide hole 112, which is connected to the anti-sway hole 111 mentioned above. The hoisting component 3 has a guide part 34, which is slidably connected to the guide hole 112. The projection of the guide hole 112 onto the horizontal plane is rectangular, thus providing guidance for the up and down movement of the hoisting component 3.

[0049] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, preferably, in this embodiment, the side of the lifting member 3 facing the adjustment hole 12 is provided with an anti-detachment edge 32; the adjusting member 4 has an annular groove 43, and the anti-detachment edge 32 is disposed in the annular groove 43. Since the adjusting member 4 specifically abuts against the lifting member 3 and drives the lifting member 3 to move within the lifting hole, thereby controlling the minimum height of the lifting member 3 within the lifting hole, in practical applications it has been found that during the height adjustment process, the adjusting member 4 may detach from the lifting member 3 and fail to drive the lifting member 3 to move, leading to a failure in height adjustment. To solve this problem, the lifting member 3 is provided with an anti-detachment edge 32, and the adjusting member 4 is provided with an annular groove 43. The anti-detachment edge 32 can be disposed within the annular groove 43. Therefore, during the specific height adjustment process, the anti-detachment edge 32 and the annular groove 43 cooperate to keep the adjusting member 4 and the lifting member 3 connected, better achieving synchronous movement and making the height adjustment process more stable.

[0050] Specifically, please refer to Figure 3 , Figure 3 The diagram shows an assembly state where the adjusting component 4 is not fully assembled into the adjusting hole 12, and the anti-detachment edge 32 is not connected to the annular groove 43. At this point, the operator rotates the adjusting component 4 to move it axially along the adjusting hole 12. When the operating end 42 of the adjusting component 4 enters the adjusting hole 12, the purpose of fully assembling the adjusting component 4 into the adjusting hole 12 is achieved. For details, please refer to [reference needed]. Figure 4 In the assembly state shown, the adjusting member 4 is at its lowest position relative to the adjusting hole 12, and the anti-detachment edge 32 is connected to the annular groove 43. Furthermore, due to the friction or obstruction of the anti-detachment protrusion 131, the operating end 42 of the adjusting member 4 will be difficult to rotate out of the adjusting hole 12, thereby achieving the downward stroke limitation of the adjusting member 4 and the lifting member 3.

[0051] Specifically, please refer to Figure 5 , Figure 5 The assembly state of the adjusting component 4 after it is tilted upward a certain distance relative to the adjusting hole 12 is shown. At this time, the anti-detachment edge 32 and the annular groove 43 remain connected to ensure that the adjusting component 4 and the lifting component 3 are in the connected state.

[0052] Please see Figure 8 and Figure 9Furthermore, this utility model embodiment also provides a hanging wheel installation structure, including the hanging wheel as described above, as well as a connector 6 and a fixing member 7. The connector 6 is used to connect the door leaf, the lower end of the hanging component 3 is embedded and connected to the connector 6, and the fixing member 7 is snapped between the lower end of the hanging component 3 and the connector 6 to fix the hanging component 3 and the connector 6. In this way, the hanging wheel installation structure is connected to the door leaf through the connector 6, the lower end of the hanging component 3 is embedded and connected to the connector 6, and then fixed by snapping the fixing member 7 between the lower end of the hanging component 3 and the connector 6. This connection method eliminates the traditional complicated installation steps, is simple and intuitive to operate, and can be installed by professionals without long-term training, which greatly improves installation efficiency and reduces installation costs.

[0053] like Figure 8 and Figure 9 As shown, preferably, in this embodiment, the lower end of the hoisting member 3 is provided with a laterally extending locking block 35, the connecting member 6 is provided with a locking groove 61, the locking block 35 is embedded in the locking groove 61, the locking groove 61 has an upper top wall 611, the upper top wall 611 is located above the locking block 35, the fixing member 7 is engaged in the locking groove 61, and the upper top wall 611 and the fixing member 7 are clamped and fixed to the locking block 35 from above and below. Thus, on the one hand, the lower end of the lifting component 3 has a horizontally extending locking block 35, and the connecting component 6 has a matching locking groove 61. The locking block 35 is embedded in the locking groove 61. This horizontal locking connection method makes the connection between the lifting component 3 and the connecting component 6 more stable. During the frequent opening and closing of the door, it can effectively resist horizontal pulling and pushing forces, prevent relative displacement between the lifting component 3 and the connecting component 6, and ensure the stability of the hanging wheel installation structure. On the other hand, the locking groove 61 has an upper top wall 611 located above the locking block 35. After the fixing component 7 is engaged in the locking groove 61, the upper top wall 611 and the fixing component 7 clamp and fix the locking block 35 from above and below. This upper and lower clamping design further enhances the fixing effect of the locking block 35 in the locking groove 61, so that the locking block 35 is constrained in the vertical direction and cannot move up and down easily. Even if the door is subjected to a large vertical impact force, it can ensure a tight connection between the locking block 35 and the locking groove 61, and improve the reliability of the entire hanging wheel installation structure under complex working conditions.

[0054] like Figure 8 and Figure 9As shown, preferably, in this embodiment, the fixing member 7 is provided with a laterally extending wave structure 71, which is snapped into the slot 61. The upper top wall 611 and the wave structure 71 are clamped and fixed to the locking block 35 to increase friction. In this way, on the one hand, the wave structure 71 increases the friction between the fixing member 7 and the slot 61, making the fixing member 7 less prone to loosening after snapping. Even if there is a certain gap or installation error during the installation process, the wave structure 71 can maintain a tight connection between the fixing member 7 and the slot 61 through its own elastic deformation and friction, ensuring the stability of the hanging wheel installation structure after installation. On the other hand, the undulating shape of the wave structure 71 can disperse the stress applied to the connection. When the door leaf is subjected to a large instantaneous impact force, the stress will not be concentrated in a small area, but will be gradually dispersed to a larger area along the contour of the wave structure 71, thereby reducing the phenomenon of local stress concentration, improving the fatigue resistance of the connection structure, and extending the service life of the hanging wheel installation structure.

[0055] In summary, the hanging wheel and the hanging wheel mounting structure including the thereof disclosed in this utility model can bring at least the following beneficial technical effects:

[0056] 1) Sufficient space is reserved on the main body 1 for installing other functional components 5 to meet the diverse needs of different users. At the same time, the installation of the wheel body 2 is also easier. The wheel body 2 can be installed in the designated position on the main body 1 without having to consider the limitation of the travel limiting component on the installation space.

[0057] 2) The multiple anti-detachment protrusions 131 arranged around the adjustment member 4 form multi-point contact and constraint, thereby increasing the limiting force on the adjustment member 4;

[0058] 3) The adjusting part 4 is threaded to the adjusting hole 12. Due to the self-locking effect of the thread, the adjusting part 4 is not easy to loosen when subjected to external force, thus playing a role in preventing loosening.

[0059] 4) The gradually shrinking anti-sway hole 111 will form a constraint on the anti-sway part 31. When the hoisting part 3 is disturbed by the outside and has a tendency to swing in the thickness direction of the main body 1, the side wall of the anti-sway hole 111 will fit tightly with the anti-sway part 31. Through this tight contact and constraint, the swing of the hoisting part 3 in the thickness direction of the main body 1 is effectively prevented.

[0060] 5) The wave structure 71 increases the friction between the fastener 7 and the slot 61, making the fastener 7 less prone to loosening after being snapped in. Even if there is a certain gap or installation error during the installation process, the wave structure 71 can maintain a tight connection between the fastener 7 and the slot 61 through its own elastic deformation and friction, ensuring the stability of the hanging wheel installation structure after installation.

[0061] 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.
