Please refer to Figures 1 to 9. A hanger hanging pulley includes a base body 11 and a hanger body 2. The hanger body 2 includes a first split body 21 and a second split body 22. The first split body 21 and the second split body 22. The split bodies 22 are each provided with rollers, and both the first split body 21 and the second split body 22 are detachably connected to the base body 11 . Further, the first split body 21 and the second split body 22 are detachably connected. The first split body 21 and the second split body 22 are connected and combined to form the rack body 2 . When the hanger hanging pulley provided in this embodiment is used, the hanger body 2 is installed in the 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 disposed on the lower side of the hanger 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 will be described as an example).

In this embodiment, the upper surface of the base body 11 is provided with a positioning groove 111; the first split body 21 is provided with a first half shaft 212, and the second split body 22 is provided with a second half shaft corresponding to the first half shaft 212. Shaft 227; the first half shaft 212 and the second half shaft 227 are both embedded in the positioning groove 111, and the first half shaft 212 and the second half shaft 227 interact so that both can be snapped into the positioning groove 111 . Specifically, as shown in FIGS. 4 to 8 , the first half shaft 212 is disposed on the lower surface of the first split body 21 , and the second half shaft 227 is disposed on the lower surface of the second split body 22 . When the first split body 21 When connected to the second split body 22, the first half shaft 212 and the second half shaft 227 are combined to form a positioning shaft. When in use, the first split body 21 and the second split body 22 are in a connected state, and the positioning shaft composed of the first half shaft 212 and the second half shaft 227 is clamped into the positioning groove 111, thereby realizing the first split body. When 21 and the second split body 22 are connected to each other, the connection between the hanger body 2 and the base body 11 is also realized.

In this embodiment, the axial direction of the positioning shaft is parallel to the extension direction of the hanger body 2 (the extension direction of the hanger body 2 is parallel to the extension direction of the guide rail). Correspondingly, the extension direction of the positioning groove 111 is parallel to the axial direction of the positioning shaft. parallel. The connection structure between the positioning shaft and the positioning groove 111 also facilitates the disassembly and assembly between the hanger body 2 and the base body 11 . In this embodiment, the positioning groove 111 penetrates one end surface of the base body 11 in its extending direction.

Further, in order to facilitate the assembly of the first half shaft 212 and the second half shaft 227 with the positioning groove 111, in this embodiment, the end of the first half shaft 212 is provided with a first semi-guide head 2121, and the second half shaft 227 is provided with a first semi-guide head 2121. A second semiconductor head 2271 corresponding to the first semiconductor head 2121 is provided at the end; the first semiconductor head 2121 and the second semiconductor head 2271 are both equipped with small ends, and the small ends face away from the corresponding first Half shaft 212 and second half shaft 227 are provided. In this embodiment, when the first separate body 21 and the second separate body 22 are connected, the first semiconductor head 2121 and the second semiconductor head 2271 are combined to form a guide head. Specifically, as shown in Figures 6, 7 and 8, the guide head is cone-shaped and its small end is arranged away from the positioning shaft. The guide head here facilitates the positioning shaft to be accurately inserted into the positioning groove 111 . In this embodiment, preferably, the guide head is in the shape of a cone. At the same time, the first semiconductor head 2121 and the second semiconductor head 2271 here can also play a role in preventing fooling. In actual use, it can avoid installing the first split body 21 and the second split body 22 upside down, which is beneficial to improving work efficiency. efficiency.

In this embodiment, a connector 12 is provided on the other end surface of the base body 11 for fixedly mounting the hanger pulley to the damper 9 . The connector 12 is provided with a modeling hole 121 for accommodating the guide head. In this embodiment, the connector 12 is also provided with a through hole 122 for passing bolts to securely connect the damper 9 .

In this embodiment, as shown in FIGS. 4 and 5 , the inner wall of the positioning groove 111 is configured with an arc-shaped concave surface 1111 , and both the first half-shaft 212 and the second half-shaft 227 are configured with arc-shaped concave surfaces 1111 that match the arc-shaped concave surface 1111 . The arc-shaped concave surface 1111 and the arc-shaped convex surface 3 slide and fit together. Specifically, the main part of the cross-section of the positioning groove 111 is arc-shaped, and the width of the part of the positioning groove 111 that penetrates 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 in the vertical direction is Narrow at the top and wide at the bottom. In this embodiment, the positioning shaft matches the shape of the positioning groove 111. Therefore, during assembly, the positioning shaft is inserted into the positioning groove 111 from one end of the positioning groove 111 along the extending direction of the positioning groove 111, and the hanging is completed. Installation of rack body 2 and base body 11. 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 acted upon by a longitudinal external force, it will not separate from the hanger body 2; on the other hand, When the hanger body 2 and/or the base body 11 is acted upon by an external force (a force that is perpendicular to the central axis of the positioning shaft and the positioning groove 111 and does not intersect with the central axis of the positioning shaft and the positioning groove 111), the positioning shaft can move in the positioning position. The groove 111 rotates relative to the positioning groove 111, and the rotation axis is parallel to the axial direction of the positioning axis. Applied in the door panel installation scenario 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 when the door panel is suspended in the air, under the action of the door panel's gravity, the base The 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 for the automatic realization of the ideal installation state of the door panel (the door panel is vertical to the ground). It can prevent door panels from being deformed and damaged and extend the service life of door panels.

In this embodiment, the base body 11 is placed on the lower side of the hanger body 2; the upper surface of the base body 11 and the lower surface of the hanger body 2 (the lower surface of the first split body 21 or the lower surface of the second split body 22, There is a first gap 4 as shown in Figure 5 between the lower surface of the first separate body 21 and the lower surface of the second separate body 22 (which is flush). 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 within a small range of the positioning groove 111 and the positioning shaft can be eliminated. Due to the influence of production and assembly errors of the hanging pulley, the door panel can be adjusted vertically to the ground through a small range of relative rotation between the positioning groove 111 and the positioning shaft. Therefore, in order to prevent the door panel from swinging significantly during use, that is, from a wide range of relative rotation between the positioning groove 111 and the positioning shaft, in this embodiment, preferably, the width of the first gap 4 is 1 mm. The first gap 4 here can ensure the relative rotation between the positioning shaft and the positioning groove 111, and at the same time can prevent the rotation range between the two from being too large, and the safety is high.

In this embodiment, as shown in FIGS. 4 and 5 , the positioning shaft can be understood as being cylindrical, and the main part of the positioning groove 111 is adapted to the cylindrical shape of the positioning shaft. The matching structure of the arc-shaped concave surface 1111 and the arc-shaped convex surface 3 can effectively reduce the friction between the positioning shaft and the positioning groove 111 when they rotate, prevent them from being stuck due to excessive friction, and facilitate the connection between the positioning shaft and the positioning groove 111. relative rotation.

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 spherical hinge structure. At this time, both the first half shaft 212 and the second half shaft 227 have hemispherical structures.

In this embodiment, as shown in Figures 2, 6, 7 and 8, the first half shaft 212 is provided with a first limiting half hole 2122 and a third limiting half hole 214. The second half shaft 227 is provided with a first limiting half hole 2122 and a third limiting half hole 214. A second limiting half hole 2272 and a fourth limiting half hole 228 are configured; 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 form a third limiting half hole. A limiting hole, the third limiting half hole 214 and the fourth limiting half hole 228 constitute a second limiting hole; the base body 11 is provided with a first limiting shaft 13 and a hanging rod respectively (not shown in the figure, The hanging rod is used for hanging door panels), 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 penetrates the base body 11 and is threadedly connected with the base body 11 . 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 then the first limiting shaft 13 is The limiting shaft 13 can position the positioning shaft (ie, the first half shaft 212 and the second half shaft 227) in the positioning groove 111 in its axial direction. It should be noted that, in order to facilitate installation, the first limit hole and the first limit shaft 13 are allowed to have a gap in the axial direction of the positioning shaft. The gap is in the range of 0.5-1.5 mm, which facilitates installation while ensuring that the base body 11 and the installation accuracy of the rack body 2. And the first limiting hole and the first limiting shaft 13 have a large gap in the axial direction of the wheel axis (that is, the swing direction of the base part relative to the hanger part), and the gap is so as not to affect the base part relative to the hanger part. The swing shall prevail. That is, when in use, when the upper surface of the base body 11 is in contact with the lower surface of the hanger body 2, there is still a gap between the first limiting shaft 13 and the first limiting hole in the swing direction of the base part relative to the hanger part. .

Furthermore, the base body 11 is provided with a threaded hole 1112 for installing 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 for hoisting the door panel. The cooperation between the inner end of the hanging rod and the second limit hole is the same as the cooperation between the first limit shaft 13 and the first limit hole, and the working principle is the same, which will not be described again here.

Furthermore, the upper surface of the base body 11 is an arc-shaped surface, or the lower surface of the hanger body 2 is an arc-shaped surface. In this embodiment, preferably, the upper surface of the base body 11 is an upward convex arc surface. The arcuate surface structure design here can achieve a larger rotation of the positioning shaft relative to the positioning groove 111 when the width of the first gap 4 is small (the larger amplitude here is compared to the upper surface of the base body 11 and the lower surface of the hanger body 2 are both planar), ensuring the compactness of the hanger pulley structure and high safety.

In this embodiment, the bottom surface of the positioning groove 111 is the first limiting plane 7, and the second limiting plane 6 is arranged on the positioning shaft; when the positioning shaft is engaged in the positioning groove 111, the first limiting plane 7 and the second limiting plane 7 are disposed on the positioning shaft. A second gap 5 is formed between the two limiting planes 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 relative rotation between the positioning shaft and the positioning groove 111 on the basis of the first gap 4, and at the same time to prevent friction between the two. The rotation range is 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 when the first gap 4 is effective. The two will only come into play when the first gap 4 fails (the first gap 4 is larger than the second gap 5).

Further, the first split body 21 is provided with a guide groove 211, and the second split body 22 is provided with a guide protrusion 222 that matches the guide groove 211; or the second split body 22 is provided with a guide groove 211, and the first split body 22 is provided with a guide groove 211. The split body 21 can be provided with a guide protrusion 222 that matches 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 split body 21 and the second split body 22, a guide groove 211 is provided on the inner side of the first split body 21, and a guide groove 211 is provided on the inner side of the second split body 22. The guide groove 211 is adapted to the guide protrusion 222 . More specifically, as shown in Figures 7 and 8, 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 hanging pulley in the guide rail. When in use, the inner side of the first split body 21 is opposite to the inner side 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, so as to align the first split body 21 with the inner side of the second split body 22. The body 21 and/or the second split body 22 exert force 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 form the aforementioned third half hole. There is only one limiting hole, and the third limiting half hole 214 and the fourth limiting half hole 228 constitute the aforementioned second limiting hole. Finally, the rack body 2 and the base body 11 composed of the first split body 21 and the second split body 22 are installed. The guide groove 211 here cooperates with the structural design of the guide protrusion 222 to facilitate the rapid assembly of the first split body 21 and the second split body 22 .

In this embodiment, the hanger body 2 is designed as a detachable structure such as a first split body 21 and a second split body 22 to facilitate the installation of the hanger body 2 in the guide rail, that is, the first split body 21 The first split body 21 and the second split body 22 are installed into the guide rails respectively, and then they are moved in the guide rail and cooperate with each other through the guide protrusion 222 and the guide groove 211 to assemble the first split body 21 and the second split body 22. During assembly, The rack body 2 is divided into parts, thereby reducing the overall size of the rack body 2 during the process of installing the rack body 2 into the guide rail, making it easier to install the rack body 2 into the guide rail, which can effectively improve the disassembly and assembly efficiency of the rack 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 hanger body 2 faster; at the same time, it avoids the installation of the guide rail in the traditional process. The access structure opened on the side wall ensures the structural strength of the guide rail and high safety; and through the structural design of combining the first split body 21 and the second split body 22 with the base body 11, a hanger hanging pulley is added structural stability.

In this embodiment, preferably, the structures of the first split body 21 and the second split body 22 are basically consistent and symmetrical. The assembled first split body 21 and the second split body 22 are basically symmetrically arranged and located directly above the base body 11, thus having strong structural stability.

Further, in order to stabilize the structure of the assembled first split body 21 and the second split body 22 and facilitate subsequent assembly with the base body 11, in this embodiment, as shown in Figures 6, 7 and 8, in Magnets 213 corresponding to the guide protrusions 222 are provided in the guide groove 211 .

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 here 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 .

In this embodiment, as shown in Figures 4, 5 and 7, the guide groove 211 is a trapezoidal groove. Specifically, as shown in FIG. 4 , the large end of the guide groove 211 is disposed toward the second split body 22 . Furthermore, the end of the guide protrusion 222 facing the guide groove 211 is configured with a chamfer, so that it can match the guide groove 211 and facilitate the guide protrusion 222 to be embedded in the guide groove 211 .

In other embodiments, the guide groove 211 may have its small end facing the second body 22 , and similarly, the shape of the guide protrusion 222 is adapted to the shape of the guide groove 211 . At this time, the structural design of the guide groove 211 and the guide protrusion 222 can not only facilitate the rapid assembly of the first split body 21 and the second split body 22, but also can firmly connect the first split body 21 and the second split body 22, so that The first split body 21 and the second split body 22 can only be detached from the direction in which the guide groove 211 extends.
