The embodiment of the present invention provides an elastically movable pulley assembly, as shown in fig. 1-2, which includes a mounting plate 100 and a connecting seat 200, the connecting seat 200 is rotatably connected with a plurality of first pulleys 310, and the first pulleys 310 are used for sliding fit with a rail, so that the whole pulley assembly can slide on the rail. The connection holder 200 is provided at one side of the mounting plate 100 and slidably coupled with the mounting plate 100 in a vertical direction, so that the connection holder 200 and the first pulley 310 can be synchronously moved in the vertical direction with respect to the mounting plate 100. The other side of the mounting plate 100 is adapted to be coupled to the door body to secure the entire sheave assembly to the door body.

The mounting plate 100 is fixed with a support plate 110, the support plate 110 and the connecting seat 200 are located on the same side of the mounting plate 100, and the support plate 110 is located below the connecting seat 200. An elastic member 410 is disposed between the connecting seat 200 and the supporting plate 110, the elastic member 410 abuts against the connecting seat 200 and the supporting plate 110, respectively, and the connecting seat 200 can move elastically in a vertical direction relative to the supporting plate 110 under the action of the elastic member 410. When the track is uneven, the connecting seat 200 can make the first pulley 310 self-adaptively cling to the track through the elastic movement in the vertical direction, so as to ensure the effective contact of the first pulley 310 and the track, and the whole pulley assembly moves more stably and smoothly on the track, so that a user can open or close the sliding door more conveniently.

In some embodiments, the support plate 110 is provided with a guide rod 420 extending along a vertical direction, the connection base 200 is provided with a through hole adapted to the guide rod 420 and penetrating through the connection base, specifically, the extending direction and the size of the through hole are respectively adapted to the extending direction and the size of the guide rod 420, and the guide rod 420 penetrates through the through hole and can move in the through hole along the vertical direction, so that the sliding connection between the connection base 200 and the mounting plate 100 can be realized through the cooperation of the guide rod 420 and the through hole.

Further, the connection block 121 is fixed on the mounting plate 100 above the connection block 200, and the guide rod 420 passes through the through hole and is connected to the connection block 121, so that both ends of the guide rod 420 are connected to the connection block 121 and the support plate 110, respectively, so that the guide rod 420 is kept stable, and the connection block 200 slides more smoothly on the guide rod 420. Meanwhile, the support plate 110 and the connection block 121 may restrict the connection holder 200 from being separated from the guide rod 420, so that the connection holder 200 maintains the sliding connection with the guide rod 420.

Furthermore, the elastic member 410 is a spring sleeved on the guide rod 420, so that the spring is not easily separated from the guide rod 420, and a stable elastic force can be applied to the connecting base 200.

In some embodiments, since the connecting seat 200 has a certain length, two sets of elastic members 410 may be provided, and the two sets of elastic members 410 are respectively abutted against the connecting seat 200 and the supporting plate 110 to provide a relatively uniform elastic force to keep the connecting seat 200 stable.

The bottom of outer pedestal 210 is provided with the storage tank, and interior pedestal 220 sets up in the storage tank, and interior pedestal 220 can move along the horizontal direction in the storage tank, and is specific, and the size of storage tank on the horizontal direction can be made bigger than the size of interior pedestal 220 to reserve the activity space, supply interior pedestal 220 to move along the horizontal direction in the storage tank. The through holes of the connection seat include a first through hole penetrating the outer seat 210 and a second through hole penetrating the inner seat 220, so that the first through hole and the second through hole both extend in the vertical direction, and the first through hole is in butt joint with the second through hole, and the guide rod 420 passes through the first through hole and the second through hole and can move in the vertical direction in the first through hole and the second through hole. The aperture of the second through-hole may be slightly larger than the outer diameter of the guide rod 420 so that the guide rod 420 may move in the vertical direction in the second through-hole but may be difficult to deflect in the second through-hole or move in the radial direction of the second through-hole. The first through-hole has a larger diameter than the outer diameter of the guide rod 420 so that the guide rod 420 can move in the first through-hole in a horizontal direction, i.e., the guide rod 420 can move in the first through-hole in a radial direction of the first through-hole.

For some pulley assemblies, the connecting seat needs to deflect a certain angle relative to the mounting plate 100, so that the angle of the pulley is more adaptive to the angle of the rail, for example, in the chinese utility model patent with publication No. CN213597730U, the inner support of the patent can swing left and right relative to the fixed seat to adjust the angle of the pulley. The interior pedestal 220 of this embodiment can move and guide arm 420 can move along the horizontal direction in the storage tank along the horizontal direction in first perforation, and this is just on the basis that the connecting seat can be relative mounting panel 100 along vertical elastic movement, and the space has been reserved for outer pedestal 210 can deflect certain angle relative to mounting panel 100, conveniently carries out the regulation of a plurality of dimensions to the connecting seat for the pulley is laminated with the track more.

As to how to realize that the outer seat body 210 can deflect a certain angle relative to the mounting plate 100, a person skilled in the art may adopt the technical solution described in the chinese utility model patent with the publication number CN213597730U, or may adopt other technical solutions in the prior art.

It should be noted that the specific size of the receiving groove, the specific size of the inner base 220, the aperture of the first through hole, and the specific numerical value of the outer diameter of the guide rod 420 can be determined by those skilled in the art according to actual situations.
