Description

Technical Field

The present disclosure relates to the technical field of hardware accessories and, particularly, to a hanger-type hanging sliding wheel and a using method thereof.

Background of the Invention

The hanging sliding wheel is an important component of sliding doors and is generally used by cooperating with a damper. When in use, the door panel is mounted on the guiding track through a hanging sliding wheel, so that the door panel moves easily in an extension direction of the guiding track, which realizes the opening and closing of the door panel.
In order to assemble with the guiding track, a width of the hanging sliding wheel is designed to be larger than a width of the guiding track slot opening, which increases the difficulty of installing the hanging sliding wheel. In order to facilitate the assembly of the hanging sliding wheel, the hanging sliding wheel is often installed by providing a maintenance opening in a side wall of the guiding track, increasing the cost of installing the hanging sliding wheel and causing a reduction in the structural strength of the guiding track, which affects the service life of the guiding track and the efficiency of the installation of the hanging sliding wheel. Different forms of detachable hanging sliding wheels have been introduced on the market since then, in which a maintenance opening may be omitted by disassembling the hanging sliding wheel and reassembling the hanging sliding wheel into the guiding track. However, the problem of inconvenient installation still exists in the actual process of assembling the hanging sliding wheel with the guiding track, which affects the construction efficiency.

Detailed Description of Embodiments

For a better understanding and implementation, the technical solutions in the embodiments of the present disclosure are clearly and completely described below in conjunction with the attached drawings of the present disclosure.
In the description of the present disclosure, it is to be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and other orientation or position relationships are based on the orientation or position relationships shown in the attached drawings. It is only intended to facilitate description and simplify operation, but not to indicate or imply that the referred device or element has a specific orientation, or is constructed and operated in a specific orientation. Therefore, they should not be construed as a limitation of the present disclosure.
Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are used only to describe specific embodiments and are not intended as a limitation of the disclosure. Referring to Fig. 1 to Fig. 9, a hanger-type hanging sliding wheel includes a base body 11 and a hanger body 2, the hanger body 2 including a first component 21 and a second component 22. Both the first component 21 and the second component 22 are provided with rollers, and both the first component 21 and the second component 22 are detachably connected to the base body 11. Further, the first component 21 and the second component 22 are detachably connected. The first component 21 and the second component 22 are connected and combined to form the hanger body 2. When using the hanger-type hanging sliding wheel 2 provided in the present embodiment, the hanger body 2 is mounted in the guiding track (not shown in figures) and is capable of being moved within the guiding track in an extension direction of the guiding track. The base body 11 is provided on a lower side of the hanger body 2 and is extended out of the guiding track, the base body 11 used for fixing and connecting door panels and other components required to be moved relative to the guiding track (examples of installing door panels to the base body 11 is illustrated as follows).
In the present embodiment, an upper surface of the base body 11 is provided with a positioning slot 111; the first component 21 is provided with a first half-shaft 212, and the second component 22 is provided with a second half-shaft 227 corresponding to the first half-shaft 212; the first half-shaft 212 and the second half-shaft 227 are both embedded in the positioning slot 111; and the first half-shaft 212 and the second half-shaft 227 interact with each other to enable both to be snap-fitted into the positioning slot 111. Specifically, as shown in Fig. 4 to Fig. 8, a lower surface of the first component 21 is provided with a first half-shaft 212, and a lower surface of the second component 22 is provided with a second half-shaft 227. The first half-shaft 212 is combined with the second half-shaft 227 to form a positioning shaft when the first component 21 and the second component 22 are connected. When in use, the first component 21 is connected to the second component 22, and the positioning shaft composed of the first half-shaft 212 and the second half-shaft 227 is snap-fitted into the positioning slot 111, which achieves the connection between the first component 21 and the second component 22, and also achieves the connection between the hanger body 2 and the base body 11.
In the present embodiment, an axial direction of the positioning shaft is parallel to an extension direction of the hanger body 2 (an extension direction of the hanger body 2 is parallel to an extension direction of the guiding track); and correspondingly an extension direction of the positioning slot 111 is parallel to an axial direction of the positioning shaft. A connection structure of the positioning shaft and the positioning slot 111 also facilitates the disassembly between the hanger body 2 and the base body 11. In the present embodiment, the positioning slot 111 penetrates an end surface of the base body 11 in the extension direction of the positioning slot 111.
Further, in order to facilitate the first half-shaft 212 and the second half-shaft 227 to assemble with the positioning slot 111, in the present embodiment, an end of the first half-shaft 212 is provided with a first half guiding head 2121, and an end of the second half-shaft 227 is provided with a second half guiding head 2271 corresponding to the first half guiding head 2121. The first half guiding head 2121 and the second half guiding head 2271 are both provided with small ends. The small ends are provided back to the corresponding first half-shaft 212 and second half-shaft 227. In the present embodiment, when the first component 21 and the second component 22 are connected, the first half guiding head 2121 is combined with the second half guiding head 2271 to form a guiding head. Specifically, as shown in Fig. 6 to Fig. 8, the guiding head is conical and the small end thereof is provided back to the positioning shaft. The guiding head facilitates the accurate embedding of the positioning shaft into the positioning slot 111. In the present embodiment, preferably, the guiding head is cone-shaped. Also, the first half guiding head 2121 and the second half guiding head 2271 may also play a role in fool-proofing, to avoid an inversely installation of the first component 21 and the second component 22, which is conducive to improving the working efficiency.
In the present embodiment, the other end face of the base body 11 is provided with a connector 12 for fixing the hanger-type hanging sliding wheel to the damper 9. A molding hole 121 is provided on the connector 12 for accommodating the guiding head. In the present embodiment, the connector 12 is also provided with a through-hole 122 for threading a bolt to fixedly connect to the damper 9.
In the present embodiment, as shown in Fig. 4 and Fig. 5, an inner wall of the positioning groove 111 is configured with an arcuate concave surface 1111; the first half-shaft 212 and the second half-shaft 227 are both configured with an arcuate convex surface 3 matching the arcuate concave surface 1111; and the arcuate concave surface 1111 and the arcuate convex surface 3 are slidably fitted. Specifically, a main part of a cross-section of the positioning slot 111 is circular-arc-shaped. A width of a portion of the positioning slot 111 penetrating an upper surface of the base body 11 is smaller than that of the main part thereof, that is, the cross-section shape of the positioning slot 111 is narrow at the top and wide at the bottom in a vertical direction. In the present embodiment, the positioning shaft is adapted to a profile of the positioning slot 111. Thus, when assembling, the installation between the hanger body 2 and the base body 11 may be simply completed by embedding an end of the positioning shaft into the positioning slot 111 along an extension direction of the positioning slot 111. On the one hand, the structural design of the positioning shaft and the positioning slot 111 may achieve the connection between the hanger body 2 and the base body 11, that is, when the base body 11 is subjected to longitudinal external forces, the base body 11 being not detached from the hanger body 2; on the other hand, when the hanger body 2 and/or the base body 11 are subjected to external forces (forces perpendicular to but not intersecting a central axis between the positioning shaft and the positioning slot 111), the positioning shaft is capable of rotating in the positioning slot 111 relative to the positioning slot 111, and a rotating axis is parallel to an axial direction of the positioning shaft. In the present embodiment, applied to a door panel installation scenario, if the door panel initially mounted on the base body 11 is inclined relative to the ground, i.e., the door panel is not perpendicular to the ground. Then, when the door panel is hanging, the base body 11 may swing relative to the hanger body 2 under the gravity of the door panel. That is, the positioning shaft is rotated relative to the positioning slot 111 until the door panel is perpendicular to the ground, so as to facilitate an automatic realization of an ideal installation state of the door panel (door panel perpendicular to the ground) and prevent the door panel from deformation and damage, thereby extending a service life of the door panel.
In the present embodiment, the base body 11 is provided on a lower side of the hanger body 2; as shown in Fig. 5, there is a first gap 4 between an upper surface of the base body 11 and a lower surface of the hanger body 2 (a lower surface of the first component 21 or a lower surface of the second component 22, and the lower surface of the first component 21 is aligned with the lower surface of the second component 22). In the present embodiment, a width of the first gap 4 is 0.5-2mm. Specifically, it is inevitable for the presence of assembly and production errors between components of the hanger-type hanging sliding wheel, but the errors are relatively small. That is to say, a relative rotation between the positioning slot 111 and the positioning shaft in a small range may eliminate the influence caused by production and assembly errors of the hanger-type hanging sliding wheel. That is, a small range of the relative rotation between the positioning slot 111 and the positioning shaft may achieve a state adjustment of the door panel perpendicular to the ground. Therefore, in order to prevent the swing of the door panel in a large range when in use, that is, in order to prevent the relative rotation between the positioning slot 111 and the positioning shaft in a large range, in the present embodiment, a width of the first gap 4 is preferably 1 mm. The first gap 4 may ensure the relative rotation between the positioning shaft and the positioning slot 111, which may also prevent excessive rotation between them, which provides a high level of safety.
In the present embodiment, as shown in Fig. 4 and Fig. 5, the positioning shaft may be understood as a cylindrical shape, and the main part of the positioning slot 111 is adapted to the cylindrical shape of the positioning shaft. The structure of the curved concave surface 1111 and the curved convex surface 3 may effectively reduce the friction when the positioning shaft and the positioning slot 111 rotate, which prevents them from getting stuck due to excessive friction, which facilitates the relative rotation between the positioning shaft and the positioning slot 111.
It is to be noted that, in other embodiments, the positioning shaft may be spherical and the fit between the positioning shaft and the positioning slot 111 resembles a ball-joint structure, in which the first half-shaft 212 and the second half-shaft 227 are both half-spherical structures.
In the present embodiment, as shown in Fig. 2, Fig. 6, Fig. 7, and Fig. 8, the first half-shaft 212 is provided with a first limiting half-hole 2122 and a third limiting half-hole 214, and the second half-shaft 227 is provided with a second limiting half-hole 2272 and a fourth limiting half-hole 228; when the first component 21 and the second component 22 are connected, the first limiting hole is formed by the first limiting half-hole 2122 and the second limiting half-hole 2272, while the second limiting hole is formed by the third limiting half-hole 214 and the fourth limiting half-hole 228. The base body 11 is provided with a first limiting shaft 13 and a hanging rod (not shown in figures, the hanging rod being used for hanging the door panel), in which the first limiting shaft 13 is extended into the first limiting hole, and the hanging rod is extended into the second limiting hole. In the present embodiment, the first limiting shaft 13 is a bolt that penetrates the base body 11 and is threaded to the base body 11. When in use, when the hanger body 2 and the base body 11 are assembled, that is, when the positioning shaft is snap-fitted into the positioning slot 111, and the first limiting shaft 13 is rotated and extended into the first limiting hole, so that the first limiting shaft 13 may position the positioning shaft (i.e., the first half-shaft 212 and the second half-shaft 227) within the positioning slot 111 in an axial direction of the positioning shaft. It is to be noted that, in order to facilitate installation, a gap is allowed between the first limiting hole and the first limiting shaft 13 in an axial direction of the positioning shaft. The gap is in a range of 0.5-1.5mm, which facilitates installation and may also ensure the mounting accuracy between the base body 11 and the hanger body 2. Moreover, a relatively large gap is provided between the first limiting hole and the first limiting shaft 13 in an axial direction of the roller (i.e., a swinging direction of the base part relative to the hanger part), in which the gap is such that it does not affect the swinging of the base part relative to the hanger part. When in use, and when the upper surface of the base body 11 is abutted against the lower surface of the hanger body 2, a gap still exists between the first limiting shaft 13 and the first limiting hole in a swinging direction of the base part relative to the hanger part.
Further, the base body 11 is provided with threaded holes 1112 for mounting the hanging rod (not shown in figures). The hanging rod here is embedded in and threaded to the threaded hole 1112. When in use, an inner end of the hanging rod is extended into the second limiting hole and an outer end is used for lifting the door panel. The role and working principle of a cooperation of the inner end of the hanging rod with the second limiting hole is equivalent to that of the first limiting shaft 13 with the first limiting hole, which is not repeated hereby.
Further, the upper surface of the base body 11 is an arcuate surface, or the lower surface of the hanger body 2 is an arcuate surface. In the present embodiment, preferably, the upper surface of the base body 11 is an upwardly convex arcuate surface. The structural design of the curved surface enables the positioning shaft, under a circumstance that a width of the first gap 4 is relatively small, to be rotated relative to the positioning slot 111 in a relatively large range (the relatively large range is in comparison to the fact that the upper surface of the base body 11 and the lower surface of the hanger body 2 are both flat), which ensures the compactness of the hanger-type hanging sliding wheel structure and provides a high level of safety.
In the present embodiment, a bottom surface of the positioning slot 111 is a first limiting plane 7, and the positioning shaft is provided with a second limiting plane 6. When the positioning shaft is snap-fitted into the positioning slot 111, a second gap 5 is formed between the first limiting plane 7 and the second limiting plane 6. A width of the second gap 5 here is slightly larger than that of the first gap 4, and the objective thereof is, based on the presence of the first gap 4, to ensure a relative rotation between the positioning shaft and the positioning slot 111, which also prevents excessive rotation between them. The second gap 5 is slightly larger than the first gap 4 to enable the first gap to be worked, so that the second limiting plane 6 and the first limiting plane 7 do not contact each other. The second limiting plane 6 and the first limiting plane 7 function only when the first gap 4 fails (when the first gap 4 is larger than the second gap 5).
Further, the first component 21 is provided with a guiding slot 211, and the second component 22 is provided with a guiding protrusion 222 adapted to the guiding slot 211; or the second component 22 is provided with a guiding slot 211, and the first component 21 is provided with a guiding protrusion 222 adapted to the guiding slot 211, in which the guiding protrusion 222 is slidably embedded in the guiding slot 211. Specially, in the present embodiment, for facilitating the assembly between the first component 21 and the second component 22, a guiding slot 211 is provided on an inner side of the first component 21, and a guiding protrusion 222 adapted to the guiding slot 211 is provided on an inner side of the second component 22. More specifically, as shown in Fig. 7 and Fig. 8, the guiding slot 211 is extended in a direction parallel to an axial direction of the positioning shaft, i.e., parallel to a moving direction of the hanger-type hanging sliding wheel within the guiding track. When in use, an inner side surface of the first component 21 is opposed to an inner side surface of the second component 22; the first component 21 and the second component 22 are separated in an extension direction of the guiding slot 211; and a force is applied to the first component 21 and/or the second component 22, so that the guiding protrusion 222 is embedded into the guiding slot 211 from an end of the guiding slot 211, which is sufficient until the first limiting hole mentioned above is formed by the first limiting half-hole 2122 and the second limiting half-hole 2272 and until the second limiting hole mentioned above is formed by the third limiting half-hole 214 and the fourth limiting half-hole 228. Finally, the hanger body 2 constituted by the first component 21 and the second component 22 is mounted to the base body 11. The structural design of the guiding slot 211 cooperating with the guiding protrusion 222 facilitates rapid assembly between the first component 21 and the second component 22.
In the present embodiment, the hanger body 2 is designed as a detachable structure with the first component 21 and the second component 22, which facilitates the installation of the hanger body 2 within the guiding track. That is, the first component 21 and the second component 22 are mounted into the guiding track respectively, and then the first component 21 and the second component 22 are moved and assembled by cooperating the guiding protrusion 222 with the guiding slot 211. The hanger body 2 may be separated from a whole component into pieces, which reduces the overall dimension of the hanger body 2 when mounting the hanger body 2 into the guiding track, so as to facilitate the hanger body 2 to be mounted into the guiding track, thereby effectively increasing the disassembling and assembling efficiency between the hanger body 2 and the guiding track. Finally, the base body 11 mounted with the damper 9 is mounted into the guiding track by the damper 9. A rapid and convenient assembly between the base body 11 and the hanger body 2 is available by using the damper 9. Also, a maintenance opening, which is provided on a side wall of the guiding track in a traditional process, may be omitted to ensure the structural strength of the guiding track and provide high safety. The structural stability of the hanger-type hanging sliding wheel is increased by the structural design of combining the first component 21 and the second component 22 to connect with the base body 11.
In the present embodiment, preferably, the structure of the first component 21 and the second component 22 is substantially identical and symmetrical. After assembling, the first component 21 and the second component 22 are substantially symmetrically provided and positioned directly above the base body 11, which provides strong structural stability.
Further, in order to stabilize the structure of the assembled first component 21 and the second component 22, for facilitating the subsequent assembly with the base body 11, in the present embodiment, as shown in Fig. 6, Fig. 7, and Fig. 8, a magnet 213 is provided in the guiding slot 211 in one-to-one correspondence with the guiding protrusion 222. The guiding protrusion 222 is mounted on an inner side of the second component 22 by a fixing screw 221, and the guiding protrusion 222 is provided with a magnetic substance that is capable of being attracted to its corresponding magnet 213. In the present embodiment, the magnet 213 is a permanent magnet, and the guiding protrusion 222 may be made of iron or magnet. Specifically, the second component 22 is provided with a third mounting hole 223, and the fixing screw 221 is embedded in the third mounting hole 223 and threaded thereto.
Further, a bottom of the guiding slot 211 is provided with an embedded slot 2112, and the magnet 213 is embedded in the embedded slot 2112. A depth of the embedded slot 2112 is larger than or equal to a thickness of the magnet 213 in order to prevent the magnet 213 from extending out of the embedded slot 2112 and affecting the assembly of the guiding protrusion 222.
In the present embodiment, the guiding slot 211 is a trapezoidal slot, as shown in Fig. 4, Fig. 5, and Fig. 7. Specifically, as shown in Fig. 4, a large end of the guiding slot 211 is provided toward the second component 22. Further, an end of the guiding protrusion 222 toward the guiding slot 211 is provided with a chamfer, so that the guiding protrusion 222 adapts to the guiding slot 211 and facilitates the guiding protrusion 222 to be embedded in the guiding slot 211.
In the other embodiment, the guiding slot 211 may be provided with a small end toward the second component 22. Similarly, the guiding protrusion 222 is adapted to the contour of the guiding slot 211. Then, the structural design of the guiding slot 211 fitted with the guiding protrusion 222 not only facilitates the rapid assembly of the first component 21 and the second component 22 but also may lead to a fixed connection between the first component 21 and the second component 22, so that the first component 21 and the second component 22 may only be disassembled from an extension direction of the guiding slot 211.
In the present embodiment, the rollers include a first roller 215 and a second roller 224. Two first rollers 215 are rotatably mounted on the first component 21 by a first pin 216 and two second rollers 224 are rotatably mounted on the second component 22 by a second pin 225. Specifically, the first component 21 is provided with a first mounting hole 2111, and the second component 22 is provided with a second mounting hole 226, in which the first pin 216 is embedded in the first mounting hole 2111 and the second pin 225 is embedded in the second mounting hole 226.
Further, for facilitating the mount between the first component 21 and the second component 22, in the present embodiment, as shown in Fig. 2, the first component 21 and the second component 22 are both provided with auxiliary holes 8. When the first component 21 and the second component 22 are mounted into the guiding track, it is conducive to installing the first component 21 and the second component 22 into the guiding track due to the narrow slots of the guiding track. Specifically, the auxiliary hole 8 is an inner hexagonal hole. Then, the staff may embed an inner hexagonal wrench into the auxiliary hole 8, so as to facilitate the elevation of the first component 21 and the second component 22, which facilitates the bottom-up mount of the first component 21 and the second component 22 into the guiding track. Also, it is convenient for the staff to move the first component 21 and the second component 22 within the guiding track with a wrench.

Firstly, the staff disassembles the hanger-type hanging sliding wheel. Specifically, the hanger body 2 and the base body 11 are disassembled, and the hanger body 2 is further disassembled into the first component 21 and the second component 22.
Then, the first component 21 and the second component 22 are mounted into the guiding track respectively.
Subsequently, the first component 21 and/or the second component 22 are moved within the guiding track to align them in the same position in an extension direction of the guiding track (specifically, the first limiting hole is formed by the first limiting half-hole 2122 and the second limiting half-hole 2272, while the second limiting hole is formed by the third limiting half-hole 214 and the fourth limiting half-hole 228), so as to be combined as the hanger body 2. Then, the positioning shaft is formed by the first half-shaft 212 and the second half-shaft 227., and the structure of the first component 21 and the second component 22 is stable under the action of the magnet 213 and the guiding protrusion 222, i.e., the structure of the positioning shaft is stable.
Then the base body 11 is mounted on the damper 9 by the connector 12 out of the guiding track, and the damper 9 and the base body 11 are mounted into the guiding track together.
Finally, the hanger body 2 is moved within the guiding track to be connected to the base body 11 by a snap-fit between the positioning shaft and the positioning slot 111, and the fixation between the base body 11 and the hanger body 2 may be achieved by correspondingly fitting the first limiting shaft 13 with the first limiting hole and fitting the hanging rod with the second limiting hole. The installation is now completed.
The rapid assembly of the hanger-type hanging sliding wheel is achieved through the above steps.
