DETAILED DESCRIPTION

[0034] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Please refer to Figures 1 to 9 A hanging pulley for a rack includes a base body 11 and a rack body 2, wherein the rack body 2 includes a first body 21 and a second body 22, wherein rollers are provided on the first body 21 and the second body 22, and the first body 21 and the second body 22 can be detachably connected to the base body 11. Furthermore, the first body 21 and the second body 22 are detachably connected. The first body 21 and the second body 22 are connected and combined to form the rack body 2. When the hanging pulley for a rack provided in this embodiment is in use, the rack body 2 is installed in a guide rail (not shown in the figure), and can move in the guide rail along the extension direction of the guide rail. The base body 11 is arranged on the lower side of the rack body 2 and extends outside the guide rail, and is used to fix and connect components such as door panels that need to move relative to the guide rail (hereinafter, the installation of door panels on the base body 11 is taken as an example for explanation).

[0038] In this embodiment, a positioning groove 111 is provided on the upper surface of the base body 11; a first semi-shaft 212 is provided on the first split body 21, and a second semi-shaft 227 corresponding to the first semi-shaft 212 is provided on the second split body 22; the first semi-shaft 212 and the second semi-shaft 227 are both embedded in the positioning groove 111, and the first semi-shaft 212 and the second semi-shaft 227 interact with each other so that both can be snapped into the positioning groove 111. Specifically, Figures 4 to 8 As shown, the lower surface of the first split body 21 is configured with a first semi-axis 212, and the lower surface of the second split body 22 is configured with a second semi-axis 227. When the first split body 21 and the second split body 22 are connected, the first semi-axis 212 and the second semi-axis 227 are combined to form a positioning axis. When in use, the first split body 21 and the second split body 22 are in a connected state, and the positioning axis formed by the first semi-axis 212 and the second semi-axis 227 is clamped into the positioning groove 111, so that the first split body 21 and the second split body 22 are connected to each other, and the connection between the bracket body 2 and the base body 11 is also achieved.

[0039] In this embodiment, the axial direction of the positioning shaft is parallel to the extension direction of the rack body 2 (the extension direction of the rack body 2 is parallel to the extension direction of the guide rail), and accordingly, the extension direction of the positioning groove 111 is parallel to the axial direction of the positioning shaft. The connection structure between the positioning shaft and the positioning groove 111 also facilitates the disassembly and assembly between the rack body 2 and the base body 11. In this embodiment, the positioning groove 111 passes through one end surface of the base body 11 in its extension direction.

[0040] Furthermore, in order to facilitate the assembly of the first semi-axle 212 and the second semi-axle 227 with the positioning groove 111, in this embodiment, a first semi-guide head 2121 is provided at the end of the first semi-axle 212, and a second semi-guide head 2271 corresponding to the first semi-guide head 2121 is provided at the end of the second semi-axle 227; the first semi-guide head 2121 and the second semi-guide head 2271 are both provided with small ends, and the small ends are arranged facing away from the first semi-axle 212 and the second semi-axle 227 corresponding thereto. In this embodiment, when the first split body 21 and the second split body 22 are connected, the first semi-guide head 2121 and the second semi-guide head 2271 are combined to form a guide head. Specifically, as Figure 6 , Figure 7 and Figure 8 As shown, the guide head is cone-shaped and its small end is arranged facing away from the positioning shaft. The guide head here facilitates the positioning shaft to be accurately embedded in the positioning groove 111. In this embodiment, preferably, the guide head is cone-shaped. At the same time, the first semi-guide head 2121 and the second semi-guide head 2271 here can also play a fool-proof role, and in actual use, it can avoid the first split body 21 and the second split body 22 from being installed upside down, which is conducive to improving work efficiency.

[0041] In this embodiment, a connector 12 is provided on the other end surface of the base body 11, which is used to fix the hanger pulley to the damper 9. A shaping hole 121 is provided on the connector 12 for accommodating the guide head. In this embodiment, a through hole 122 is also provided on the connector 12 for passing a bolt to be fixedly connected to the damper 9.

[0042] In this embodiment, Figure 4 and Figure 5As shown, the inner wall of the positioning groove 111 is provided with an arc-shaped concave surface 1111, and the first semi-axis 212 and the second semi-axis 227 are both provided with an arc-shaped convex surface 3 adapted to the arc-shaped concave surface 1111; the arc-shaped concave surface 1111 and the arc-shaped convex surface 3 are slidably fitted. Specifically, the main part of the cross section of the positioning groove 111 is in the shape of an arc, and the width of the part of the positioning groove 111 that passes through the upper surface of the base body 11 is smaller than the width of its main part, that is, the cross-sectional shape of the positioning groove 111 is narrow at the top and wide at the bottom in the vertical direction. In this embodiment, the positioning shaft is adapted to the outer shape of the positioning groove 111, so when assembling, the positioning shaft is embedded into the positioning groove 111 from one end of the positioning groove 111 along the extension direction of the positioning groove 111, and the installation of the bracket body 2 and the base body 11 can be completed. The structural design of the positioning shaft and the positioning groove 111 here can realize the connection between the hanger body 2 and the base body 11 on the one hand, that is, when the base body 11 is subjected to a longitudinal external force, it does not separate from the hanger body 2; on the other hand, when the hanger body 2 and / or the base body 11 are subjected to an external force (a force perpendicular to the central axis of the positioning shaft and the positioning groove 111, and not intersecting with the central axis of the positioning shaft and the positioning groove 111), the positioning shaft can rotate relative to the positioning groove 111 in the positioning groove 111, and the rotating shaft is parallel to the axial direction of the positioning shaft. In the door panel installation scenario applied in this embodiment, if the door panel initially installed on the base body 11 is tilted relative to the ground, that is, the door panel is not perpendicular to the ground, then at this time, when the door panel is suspended, under the action of the gravity of the door panel, the base body 11 can swing relative to the hanger body 2, that is, the positioning shaft and the positioning groove 111 rotate relative to each other until the door panel is perpendicular to the ground. It is convenient to automatically realize the ideal installation state of the door panel (the door panel is perpendicular to the ground). It can prevent the door panel from deformation and damage, and extend the service life of the door panel.

[0043] In this embodiment, the base body 11 is placed on the lower side of the rack body 2; there is a gap between the upper surface of the base body 11 and the lower surface of the rack body 2 (the lower surface of the first split body 21 or the lower surface of the second split body 22, the lower surface of the first split body 21 is flush with the lower surface of the second split body 22). Figure 5The first gap 4 shown. In this embodiment, the width of the first gap 4 is 0.5-2mm. Specifically, the assembly and production errors between the various components of the hanger pulley here exist and are inevitable, but the errors are relatively not too large, that is to say, the relative rotation of the positioning groove 111 and the positioning shaft in a small range can eliminate the influence caused by the production and assembly errors of the hanger pulley, that is, the state adjustment of the door panel perpendicular to the ground can be achieved through the relative rotation of the positioning groove 111 and the positioning shaft in a small range. Therefore, in order to prevent the door panel from swinging greatly during use, that is, the relative rotation of the positioning groove 111 and the positioning shaft in a large range, in this embodiment, preferably, the width of the first gap 4 is 1mm. The first gap 4 here can ensure that the positioning shaft and the positioning groove 111 can rotate relative to each other, and at the same time can prevent the rotation amplitude between the two from being too large, and the safety is high.

[0044] In this embodiment, Figure 4 and Figure 5 As shown, the positioning shaft can be understood as a cylindrical shape, and the main part of the positioning groove 111 is adapted to the cylindrical shape of the positioning shaft. The structure of the arc concave surface 1111 and the arc convex surface 3 can effectively reduce the friction between the positioning shaft and the positioning groove 111 when rotating, prevent the two from getting stuck due to excessive friction, and facilitate the relative rotation of the positioning shaft and the positioning groove 111.

[0045] It should be noted that, in other embodiments, the positioning shaft may be spherical, and its cooperation with the positioning groove 111 is similar to a ball joint structure. In this case, both the first semi-shaft 212 and the second semi-shaft 227 are hemispherical structures.

[0046] In this embodiment, Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the first semi-axis 212 is provided with a first limiting half hole 2122 and a third limiting half hole 214, and the second semi-axis 227 is provided with a second limiting half hole 2272 and a fourth limiting half hole 228; when the first split body 21 and the second split body 22 are connected, the first limiting half hole 2122 and the second limiting half hole 2272 constitute the first limiting hole, and the third limiting half hole 214 and the fourth limiting half hole 228 constitute the second limiting hole; the base body 11 is provided with a first limiting shaft 13 and a hanging rod (not shown in the figure, the hanging rod is used to hang the door panel), wherein: the first limiting shaft 13 extends into the first limiting hole, and the hanging rod extends into the second limiting hole. In this embodiment, the first limiting shaft 13 is a bolt, which passes through the base body 11 and is threadedly connected to the base body 11. When in use, after the hanger body 2 and the base body 11 are assembled, that is, when the positioning shaft is clamped in the positioning groove 111, the first limiting shaft 13 is rotated so that it extends into the first limiting hole, and the first limiting shaft 13 can position the positioning shaft (that is, the first semi-axis 212 and the second semi-axis 227) in the positioning groove 111 in its axial direction. It should be noted that, in order to facilitate installation, the first limiting hole and the first limiting shaft 13 are allowed to have a gap in the axial direction of the positioning shaft, and the gap is in the range of 0.5-1.5mm, which is convenient for installation and can ensure the installation accuracy of the base body 11 and the hanger body 2. And the first limiting hole and the first limiting shaft 13 have a large gap in the axial direction of the wheel axle of the roller (that is, the swing direction of the base part relative to the hanger part), and the gap is based on not affecting the swing of the base part relative to the hanger part. That is, when in use, when the upper surface of the base body 11 abuts against the lower surface of the hanger body 2, the first limiting shaft 13 and the first limiting hole still have a gap in the swing direction of the base part relative to the hanger part.

[0047] Furthermore, the base body 11 is provided with a threaded hole 1112 for mounting a hanging rod (not shown in the figure). The hanging rod here is embedded in the threaded hole 1112 and is threadedly connected with the threaded hole 1112. When in use, the inner end of the hanging rod extends into the second limiting hole, and the outer end is used to hang the door panel. The cooperation between the inner end of the hanging rod and the second limiting hole is the same as the cooperation between the first limiting shaft 13 and the first limiting hole, and the working principle is the same, which will not be repeated here.

[0048] Further, the upper surface of the base body 11 is an arcuate surface, or the lower surface of the bracket body 2 is an arcuate surface. In this embodiment, preferably, the upper surface of the base body 11 is an upwardly convex arcuate surface. The arcuate surface structure design here can realize a relatively large rotation of the positioning shaft relative to the positioning groove 111 when the width of the first gap 4 is relatively small (the relatively large rotation here refers to the case that the upper surface of the base body 11 and the lower surface of the bracket body 2 are both planes), thereby ensuring the compactness of the bracket hanging pulley structure and high safety.

[0049] In this embodiment, the bottom surface of the positioning groove 111 is the first limiting plane 7, and the positioning shaft is provided with a second limiting plane 6; when the positioning shaft is engaged in the positioning groove 111, a second gap 5 is formed between the first limiting plane 7 and the second limiting plane 6. The width of the second gap 5 here is slightly larger than the width of the first gap 4, and its purpose is to ensure that the positioning shaft and the positioning groove 111 can rotate relative to each other on the basis of the first gap 4, while preventing the rotation amplitude between the two from being too large. The second gap 5 is slightly larger than the first gap 4, so that the second limiting plane 6 and the first limiting plane 7 do not contact each other when the first gap 4 is effective. The two will only play a role when the first gap 4 fails (the first gap 4 is larger than the second gap 5).

[0050] Further, the first sub-body 21 is provided with a guide groove 211, and the second sub-body 22 is provided with a guide protrusion 222 adapted to the guide groove 211; or the second sub-body 22 is provided with a guide groove 211, and the first sub-body 21 can be provided with a guide protrusion 222 adapted to the guide groove 211; the guide protrusion 222 is slidably embedded in the guide groove 211. Specifically, in this embodiment, in order to facilitate the assembly of the first sub-body 21 and the second sub-body 22, the guide groove 211 is opened on the inner side surface of the first sub-body 21, and the guide protrusion 222 adapted to the guide groove 211 is arranged on the inner side surface of the second sub-body 22. More specifically, as Figure 7 and Figure 8 As shown, the extension direction of the guide groove 211 is parallel to the axial direction of the positioning shaft, that is, parallel to the moving direction of the hanger pulley in the guide rail. When in use, the inner side surface of the first split body 21 is opposite to the inner side surface of the second split body 22, and the first split body 21 and the second split body 22 are staggered in the extension direction of the guide groove 211, and the first split body 21 and / or the second split body 22 are forced to make the guide protrusion 222 embed into the guide groove 211 from the end of the guide groove 211, until the first limiting half hole 2122 and the second limiting half hole 2272 constitute the aforementioned first limiting hole and the third limiting half hole 214 and the fourth limiting half hole 228 constitute the aforementioned second limiting hole. Finally, the hanger body 2 composed of the first split body 21 and the second split body 22 is installed with the base body 11. The structural design of the guide groove 211 here cooperates with the guide protrusion 222 to facilitate the rapid assembly of the first split body 21 and the second split body 22.

[0051] In this embodiment, the rack body 2 is designed as a detachable structure of the first split body 21 and the second split body 22, so that the installation of the rack body 2 in the guide rail is convenient. The first split body 21 and the second split body 22 can be respectively installed in the guide rail, and then the two are moved in the guide rail and the first split body 21 and the second split body 22 are assembled by cooperating with each other through the guide protrusion 222 and the guide groove 211. The rack body 2 can be broken into parts during assembly, thereby reducing the overall size of the rack body 2 during the process of installing it in the guide rail, which is convenient for the installation of the rack body 2. The guide rail can be inserted to effectively improve the efficiency of disassembly and assembly of the bracket body 2 and the guide rail; finally, the base body 11 with the damper 9 installed is installed into the guide rail through the damper 9. The use of the damper 9 makes the assembly of the base body 11 and the bracket body 2 faster; at the same time, the inspection port structure opened on the side wall of the guide rail in the traditional process is avoided, the structural strength of the guide rail is ensured, and the safety is high; and the structural stability of the bracket hanging pulley is increased by the structural design of the combined connection of the first split body 21 and the second split body 22 with the base body 11.

[0052] In this embodiment, preferably, the structures of the first sub-body 21 and the second sub-body 22 are substantially consistent and symmetrical. The assembled first sub-body 21 and the second sub-body 22 are substantially symmetrically arranged and located directly above the base body 11, and the structure has strong stability.

[0053] Furthermore, in order to stabilize the structure of the first sub-body 21 and the second sub-body 22 after assembly and facilitate the subsequent assembly with the base body 11, in this embodiment, Figure 6 , Figure 7 and Figure 8 As shown, a magnet 213 corresponding to the guide protrusion 222 is provided in the guide groove 211. The guide protrusion 222 here is installed on the inner side of the second split body 22 by a fixing screw 221, and the guide protrusion 222 is provided with a magnetic material, and the magnetic material can attract each other with the corresponding magnet 213. In this embodiment, the magnet 213 is a permanent magnet, and the guide protrusion 222 can be made of iron or a magnet. Specifically, a third mounting hole 223 is provided on the second split body 22, and the fixing screw 221 is embedded in the third mounting hole 223 and is threadedly connected thereto.

[0054] Furthermore, the bottom of the guide groove 211 is provided with an embedding groove 2112, and the magnet 213 is embedded in the embedding groove 2112. The depth of the embedding groove 2112 is greater than or equal to the thickness of the magnet 213 to prevent the magnet 213 from extending outside the embedding groove 2112 and affecting the assembly of the guide protrusion 222.

[0055] In this embodiment, Figure 4 , Figure 5 and Figure 7 As shown, the guide groove 211 is a trapezoidal groove. Figure 4As shown, the large end of the guide groove 211 is arranged toward the second split body 22. Further, the end of the guide protrusion 222 facing the guide groove 211 is chamfered so that it can be matched with the guide groove 211 and the guide protrusion 222 is conveniently embedded in the guide groove 211.

[0056] In other embodiments, the guide groove 211 may be arranged with the small end facing the second sub-body 22, and similarly, the shape of the guide protrusion 222 matches the shape of the guide groove 211. In this case, the structural design of the guide groove 211 and the guide protrusion 222 can not only facilitate the rapid assembly of the first sub-body 21 and the second sub-body 22, but also can fix the first sub-body 21 and the second sub-body 22 together, so that the first sub-body 21 and the second sub-body 22 can only be disassembled from the extension direction of the guide groove 211.

[0057] In this embodiment, the roller includes a first roller 215 and a second roller 224. The first split body 21 is rotatably mounted with two first rollers 215 via a first pin shaft 216, and the second split body 22 is rotatably mounted with two second rollers 224 via a second pin shaft 225.

[0060] First, the staff disassembles the hanging pulley of the pylon, specifically, disassembles the pylon body 2 and the base body 11, and then disassembles the pylon body 2 into a first split body 21 and a second split body 22;

[0061] Then, the first split body 21 and the second split body 22 are respectively installed into the guide rail;

[0062] Then, the first sub-body 21 and / or the second sub-body 22 are moved in the guide rail so that the two are in the same position in the extension direction of the guide rail (specifically, the first limiting half hole 2122 and the second limiting half hole 2272 constitute the first limiting hole, and the third limiting half hole 214 and the fourth limiting half hole 228 constitute the second limiting hole) to form the rack body 2 in combination. At this time, the first half shaft 212 and the second half shaft 227 constitute the positioning shaft, and the first sub-body 21 and the second sub-body 22 are structurally stable under the action of the magnet 213 and the guide protrusion 222, that is, the structure of the positioning shaft is stable;

[0063] Then, the base body 11 is mounted on the damper 9 through the connector 12 outside the guide rail, and the damper 9 and the base body 11 are installed into the guide rail;

[0064] Finally, move the bracket body 2 in the guide rail, and connect the bracket body 2 and the base body 11 in the guide rail by means of the positioning shaft and the positioning groove 111, and fix the base body 11 and the bracket body 2 by means of the first limiting shaft 13 and the hanging rod corresponding to the first limiting hole and the second limiting hole to complete the installation.

[0065] The above steps can realize the rapid assembly of the hanging pulley and the guide rail of the hanging rack.
