The present disclosure belongs to the technical field of pulley structures for a shower rooms, in particular to an adjustable pulley structure for a shower rooms.
There are two main ways to open doors in traditional shower rooms, namely, sliding doors and side-hung doors, in which sliding doors are more widely used. Sliding doors are mainly mounted by mounting pulleys on movable doors and guide rails in a shower room, so as to realize the push-pull movement of glass doors by sliding a pulley back and forth on the guide rail. In the sliding process of the pulley on the rail, the pulley will vibrate up and down, so that the sliding doors cannot move normally. In order to solve this problem, it is generally necessary to mount anti-jump devices separately after the pulley is mounted on the guide rail, which increases the mounting cost and affects the overall aesthetics of the sliding door. Moreover, the disassembly and assembly operation is also inconvenient.

The circular ring is sleeved on the circular protrusion. The pulley seat is attached to a side surface of the circular ring, and screws pass through the pulley seat and the circular ring and are screwed with the circular protrusion. The circular ring is beneficial to the normal use of the pulley assembly and can reduce the friction between the pulley assembly and the mounting column.
An end surface of the mounting seat is integrally formed with a convex block 4 with an adjusting strip-shaped concave cavity 3. In this embodiment, the adjusting strip-shaped cavity is mainly used for the mounting and positioning of the mounting column. The mounting column can also be adjusted and used in the adjusting strip-shaped cavity. When in use, the mounting column can be buffered and adjusted in the adjusting strip-shaped cavity. The mounting columns are provided in a square shape. A width of the square column is matched with a width of the adjusting strip-shaped cavity, and a length of the square column is small than a length of the adjusting strip-shaped cavity. The transverse perforation is provided in a length direction of the adjusting strip-shaped cavity.

The pulley assembly 1 includes a pulley seat 1-1, a bearing 1-2 and a pulley body 1-3; the pulley seat is fixed on a side surface of the mounting column by screws, and the pulley body is fixed on the pulley seat by bearings. In order to improve the overall decorative performance, an end surface of the pulley seat is buckled with a protective cover 16.
The present disclosure is reasonable in structure, and is provided with a mounting structure. The mounting structure includes a mounting seat, a gland, a door leaf clamping structure, a mounting column, a worm gearing structure and an adjusting screw, which not only can quickly realize the mounting and positioning of a door leaf. Moreover, the adjustment locking limit is realized through the worm gearing structure matched with the adjusting screw, which can effectively prevent the adjusting screw from automatically rotating due to vibration in the use process, thus avoiding the door leaf from loosening and sagging. The present disclosure is beneficial to improving the use smoothness and reliability, strong in applicability and excellent in practicability.
Moreover, the adjusting disc is matched with the transmission gear on the adjusting screw, so that the adjusting precision can be improved. During adjustment, when the adjusting disc rotates by a large angle, the adjusting screw only rotates by a small range, so that the adjusting precision can be improved. When the pulley assembly sags or loosens when it is used for a long time, the position adjustment of the pulley assembly can be realized by the rotation of the adjusting screw, so that the use smoothness and reliability of the pulley assembly can be ensured, which is also beneficial to improving the precision, smoothness and reliability of the adjustment position.
