Unless defined otherwise, 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 belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 to 9, a hanger hanging pulley comprises a base body 11 and a hanger body 2, wherein the hanger body 2 comprises a first split body 21 and a second split body 22, rollers are respectively arranged on the first split body 21 and the second split body 22, and the first split body 21 and the second split body 22 can be detachably connected to the base body 11. Further, the first division body 21 and the second division body 22 are detachably connected. The first sub-body 21 and the second sub-body 22 are connected and combined to form the hanger body 2. When the hanger hanging pulley provided by the embodiment is used, the hanger body 2 is installed in a guide rail (not shown in the figure) and can move in the guide rail along the extending direction of the guide rail. The base body 11 is disposed at the lower side of the hanger body 2 and extends to the outside of the guide rail for fixedly connecting components such as a door panel and the like which need to move relative to the guide rail (hereinafter, the door panel is mounted on the base body 11 for example).

In this embodiment, the positioning groove 111 is formed on the upper surface of the base body 11; the first split 21 is provided with a first half shaft 212, and the second split 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 groove 111, and the first half shaft 212 and the second half shaft 227 interact to enable both to be snapped into the positioning groove 111. Specifically, as shown in fig. 4 to 8, the lower surface of the first division body 21 is provided with a first half shaft 212, and the lower surface of the second division body 22 is provided with a second half shaft 227, and when the first division body 21 and the second division body 22 are connected, the first half shaft 212 and the second half shaft 227 are combined to constitute a positioning shaft. In use, the first and second sub-bodies 21 and 22 are connected, and the positioning shaft composed of the first half shaft 212 and the second half shaft 227 is clamped into the positioning groove 111, so that the first and second sub-bodies 21 and 22 are connected with each other, and the hanger body 2 is connected with the base body 11.

In this embodiment, the axial direction of the positioning shaft is parallel to the extending direction of the hanger body 2 (the extending direction of the hanger body 2 is parallel to the extending direction of the guide rail), and correspondingly, the extending direction of the positioning groove 111 is parallel to the axial direction of the positioning shaft. The connecting structure of 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 through one end surface of the base body 11 in the extending direction thereof.

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 the present embodiment, the end of the first half shaft 212 is provided with a first semi-pilot 2121, and the end of the second half shaft 227 is provided with a second semi-pilot 2271 corresponding to the first semi-pilot 2121; each of the first half pilot 2121 and the second half pilot 2271 is configured with a small end, and the small ends are disposed opposite to the corresponding first half shaft 212 and the corresponding second half shaft 227. In this embodiment, when the first and second sub-bodies 21 and 22 are connected, the first and second

semi-conductive heads

2121 and 2271 are combined to constitute a guide head. Specifically, as shown in fig. 6, 7 and 8, the guiding head is conical and the small end of the guiding head is arranged opposite to the positioning shaft. The guide head facilitates accurate insertion of the positioning shaft into the positioning slot 111. In this embodiment, the guide head is preferably conical. Meanwhile, the first half-lead 2121 and the second half-lead 2271 can also play a fool-proof role, so that the first sub-body 21 and the second sub-body 22 can be prevented from being reversely assembled in actual use, and the work efficiency can be improved.

In this embodiment, a connector 12 is disposed on the other end surface of the base body 11 for fixedly mounting the hanger hanging pulley to the damper 9. The connector 12 is provided with a shaping hole 121 for accommodating the guiding head. In this embodiment, the connector 12 is further provided with a through hole 122 for passing a bolt to be fixedly connected with the damper 9.

In this embodiment, as shown in fig. 4 and 5, an arc concave 1111 is configured on the inner wall of the positioning groove 111, and an arc convex surface 3 adapted to the arc concave 1111 is configured on each of the first half shaft 212 and the second half shaft 227; the arc concave 1111 and the arc convex 3 are in sliding fit. Specifically, the main portion of the cross section of the positioning groove 111 is circular arc-shaped, and the width of the portion of the positioning groove 111 penetrating the upper surface of the base body 11 is smaller than the width of the main portion thereof, i.e., the cross section of the positioning groove 111 is vertically narrow and wide. In this embodiment, the positioning shaft is matched with the positioning groove 111 in shape, so that 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 during assembly, and the mounting of the hanger body 2 and the base body 11 can be completed. The structural design of the positioning shaft and the positioning groove 111 can realize the connection between the hanger body 2 and the base body 11 on one hand, namely, the base body 11 is not separated from the hanger body 2 when being acted by longitudinal external force; on the other hand, when the hanger body 2 and/or the base body 11 is subjected to an external force (a force perpendicular to the positioning shaft and the central axis of the positioning groove 111, and not intersecting with the positioning shaft and the central axis of the positioning groove 111), the positioning shaft can rotate relative to the positioning groove 111 within the positioning groove 111, and the rotating shaft is parallel to the axial direction of the positioning shaft. Use in the door plant installation scene of this embodiment, if the door plant of initial installation at base body 11 inclines for ground, this door plant and ground out of plumb promptly, then after the door plant is unsettled, under the effect of door plant gravity, base body 11 can swing for hanger body 2, location axle and constant head tank 111 relatively rotate promptly, until the door plant is perpendicular with ground. The ideal installation state of the door panel (the door panel is vertical to the ground) can be automatically realized. The door plate can be prevented from being deformed and damaged, and the service life of the door plate is prolonged.

In this embodiment, the base body 11 is disposed at the lower side of the hanger body 2; a first gap 4 shown in fig. 5 is provided between the upper surface of the base body 11 and the lower surface of the hanger body 2 (the lower surface of the first divided body 21 or the lower surface of the second divided body 22, and the lower surface of the first divided body 21 is flush with the lower surface of the second divided body 22). In this embodiment, the width of the first gap 4 is 0.5-2 mm. Specifically, assembly and production errors among various parts of the hanging rack hanging pulley exist and are unavoidable, but the errors are not too large, namely, the positioning groove 111 and the positioning shaft rotate relatively within a small range, so that influences caused by production and assembly errors of the hanging pulley can be eliminated, and the state adjustment of the door panel perpendicular to the ground can be realized through the positioning groove 111 and the positioning shaft rotating relatively within a small range. Therefore, in order to prevent the door panel from swinging greatly during use, i.e. the positioning slot 111 and the positioning shaft rotate relatively in a large range, in the present embodiment, the width of the first gap 4 is preferably 1 mm. The first gap 4 can ensure the relative rotation between the positioning shaft and the positioning groove 111, and can prevent the overlarge rotation amplitude between the positioning shaft and the positioning groove, so that the safety is high.

In this embodiment, as shown in fig. 4 and 5, the positioning shaft may be understood as a cylinder, and the main body portion of the positioning groove 111 is adapted to the cylindrical shape of the positioning shaft. Arc concave 1111 and 3 complex structures of arc convex surface can effectively reduce the frictional force when location axle and constant head tank 111 rotate, prevent to lead to the card to die because of frictional force is too big between the two, are convenient for fix a position the relative rotation of axle and constant head tank 111.

It should be noted that in other embodiments, the positioning shaft may be a spherical ball, and the positioning groove 111 is similar to a spherical hinge structure. The first half shaft 212 and the second half shaft 227 are both hemispherical in structure.

In the present embodiment, as shown in fig. 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, 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 and

second split bodies

21 and 22 are connected, the first and second limiting

half holes

2122 and 2272 constitute a first limiting hole, and the third and fourth limiting

half holes

214 and 228 constitute a second limiting hole; be provided with first spacing axle 13 and peg (not shown in the figure, this peg is used for hanging the door plant) on the base body 11 respectively, 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 limit shaft 13 is a bolt, which penetrates through the base body 11 and is in threaded connection with the base body 11. When the hanger is used, after the hanger body 2 and the base body 11 are assembled, namely, when the positioning shaft is clamped in the positioning groove 111, the first limiting shaft 13 is rotated so as to extend into the first limiting hole, and then the positioning shaft (namely, the first half shaft 212 and the second half shaft 227) can be axially positioned in the positioning groove 111 by the first limiting shaft 13. It should be noted that, for the convenience of installation, a gap is allowed between the first limiting hole and the first limiting shaft 13 in the axial direction of the positioning shaft, and the gap is in the range of 0.5-1.5mm, so that the installation accuracy of the base body 11 and the hanger body 2 can be ensured while the installation is convenient. And the first stopper hole and the first stopper shaft 13 have a large clearance in the axial direction of the wheel shaft of the roller (i.e., the swinging direction of the base portion with respect to the hanger portion), with the clearance being such as not to affect the swinging of the base portion with respect to the hanger portion. That is, when the upper surface of the base body 11 abuts against the lower surface of the hanger body 2 in use, the first stopper shaft 13 and the first stopper hole still have a gap in the swinging direction of the base portion with respect to the hanger portion.

Further, the base body 11 is provided with a screw hole 1112 for attaching a hanging rod (not shown). The hanger bar here fits into the threaded hole 1112 and is threaded into the threaded hole 1112. When the door hanging device is used, the inner end of the hanging rod extends into the second limiting hole, and the outer end of the hanging rod is used for hoisting the door plate. The cooperation of the inner end of the hanging rod and the second limit hole and the cooperation of the first limit shaft 13 and the first limit hole are consistent in working principle, and are not described in detail herein.

Further, 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 arc surface protruding upwards. The arc-shaped surface structural design can enable the positioning shaft to rotate relatively to the positioning groove 111 by a large margin under the condition that the width of the first gap 4 is small (the large margin is compared with the upper surface of the base body 11 and the lower surface of the hanger body 2 which are both planes), so that the compactness of the hanger hanging pulley structure is guaranteed, and the safety is high.

In this embodiment, the bottom surface of the positioning groove 111 is a first limiting plane 7, and a second limiting plane 6 is configured on the positioning shaft; when the positioning shaft is clamped 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 is slightly larger than the width of the first gap 4, so that the relative rotation between the positioning shaft and the positioning slot 111 can be ensured on the basis of the first gap 4, and the excessive rotation amplitude between the positioning shaft and the positioning slot can be prevented. 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 touch in the case of an effective first gap 4. In case the first gap 4 fails (the first gap 4 is larger than the second gap 5) both will function.

Further, a guide groove 211 is arranged on the first split body 21, and a guide protrusion 222 matched with the guide groove 211 is arranged on the second split body 22; 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 projection 222 matched with the guide groove 211; the guide projection 222 is slidably fitted in the guide groove 211. Specifically, in the present embodiment, in order to facilitate the assembly of the first and

second components

21 and 22, a guide groove 211 is formed in the inner surface of the first component 21, and a guide protrusion 222 adapted to the guide groove 211 is disposed on the inner surface of the second component 22. More specifically, as shown in fig. 7 and 8, the extending direction of the guide groove 211 is parallel to the axial direction of the positioning shaft, i.e., parallel to the moving direction of the hanger hanging pulley in the guide rail. When in use, the inner side surface of the first division body 21 is opposite to the inner side surface of the second division body 22, the first division body 21 and the second division body 22 are staggered in the extending direction of the guide groove 211, and the force is applied to the first division body 21 and/or the second division body 22 to enable the guide protrusion 222 to be embedded into the guide groove 211 from the end part of the guide groove 211 until the first limiting half hole 2122 and the second limiting half hole 2272 form the first limiting hole and the third limiting half hole 214 and the fourth limiting half hole 228 form the second limiting hole. Finally, the hanger body 2 composed of the first and second sub-bodies 21 and 22 is mounted on the base body 11. The guide grooves 211 are designed to cooperate with the guide protrusions 222 to facilitate the quick assembly of the first and second sub-bodies 21 and 22.

In the embodiment, the hanger body 2 is designed into a detachable structure of the first split body 21 and the second split body 22, so that the hanger body 2 can be conveniently installed in the guide rail, the first split body 21 and the second split body 22 can be respectively installed in the guide rail, then the first split body 21 and the second split body 22 are moved in the guide rail and are matched 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, the hanger body 2 can be completely broken during assembly, the overall size of the hanger body 2 in the process of installing the hanger body into the guide rail is reduced, the hanger body 2 is conveniently installed into the guide rail, and the disassembly and assembly efficiency of the hanger body 2 and the guide rail can be effectively improved; finally, the base body 11 provided with the damper 9 is arranged in the guide rail through the damper 9, and the base body 11 and the hanger body 2 are assembled more quickly by matching with the damper 9; meanwhile, an access hole structure formed in 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 through the structural design of combining and connecting the first sub-body 21 and the second sub-body 22 with the base body 11, the structural stability of the hanging rack hanging pulley is increased.

In the present embodiment, the first and second sub-bodies 21 and 22 preferably have substantially identical and symmetrical structures. The assembled first and second sub-bodies 21 and 22 are basically symmetrically arranged and located right above the base body 11, and the structural stability is strong.
