Description

Anti-swing upper guide wheel

Technical Field

The utility model belongs to the field of sliding doors, and particularly relates to an upper guide wheel for preventing the sliding door from swinging.

Background

The sliding door adopts the guide pulley to realize the sliding guide effect of the door leaf along the door frame, and the guide pulley arranged at the top of the door leaf is commonly called as an upper guide pulley, and the upper guide pulley slides in a section bar groove at the top of the door frame and also plays a role in preventing the swing of the door leaf. The existing upper guide wheel comprises a mounting plate, a guide pillar and a guide wheel, wherein the guide wheel is sleeved on the guide pillar, one end of the guide pillar is riveted on the mounting plate, so that the guide pillar is fixed on the mounting plate, the other end of the guide pillar is riveted on the end part of the guide wheel, and the guide wheel is axially fixed, however, the riveting fixing mode makes the guide wheel difficult to assemble and disassemble, and is not easy to replace, so that the depth of a profile groove needs to be adjusted to adapt to the height of the guide wheel, and the optimal anti-swing effect is difficult to achieve.

Disclosure of Invention

Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the anti-swing upper guide wheel comprises a mounting plate 1, a guide post 2 and a guide wheel 3, wherein the mounting plate 1 is provided with

The hole 4 is connected and fixed in a section bar groove at the top of the door leaf by a screw. The guide post 2 comprises a screw rod part 5, a polished rod part 6 and a screw head part 7, wherein the screw rod part 5 is vertically connected with the mounting plate 1 in a threaded manner, and the polished rod part 6 is sleeved with the two guide wheels 3. The screw connection mounting plate is adopted as a guide pillar to mount the guide wheels, so that the guide wheels are assembled and disassembled, the number of the guide wheels is increased on the guide pillar conveniently to adjust the height of the guide wheels, and the depth of the profile groove is adapted to achieve the optimal anti-swing effect.

Each guide wheel 3 comprises a rolling bearing 8 and a lantern ring 9, the inner ring of the rolling bearing 8 is sleeved and tightly matched with the polished rod part 6, and the lantern ring 9 is sleeved and tightly matched with the outer ring of the rolling bearing 8. The collar 9 may be made of plastic or rubber, and preferably the collar 9 is made of rubber. The end of the upper rolling bearing 8 is axially sealed through the screw head 7, the end of the lower rolling bearing 8 is axially sealed through the shaft sleeve 10, the shaft sleeve 10 is tightly matched with the polish rod part 6, and the end of the shaft sleeve 10 is tightly pressed against the mounting plate 1. The rolling bearing is adopted as the guide wheel, so that the smoothness of sliding and rotating of the guide wheel along the profile groove is improved, the rolling bearing is axially sealed through the shaft sleeve and the screw head, dust is effectively prevented from entering the guide wheel, the service efficiency of the guide wheel is improved, and the service life of the guide wheel is prolonged.

What has been described above is but some of the embodiments of the utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
