Problems solved by technology

The existing pulley assembly generally only plays the role of load-bearing and sliding guide. Since the size alignment of the pulley assembly is not necessarily accurate after installation, as long as there is a little gap, the pulley assembly is easy to shake when sliding, so that the door leaf is easy to shake when moving , generate noise and bring certain safety hazards

Abstract

The invention relates to a pulley assembly with jockey pulleys. The pulley assembly comprises a main mounting block, and bearing leading pulleys capable of sliding on a guide rail are arranged on the main mounting block. According to the technical main points, the jockey pulleys capable of abutting against the inner wall of a guide rail groove to conduct sliding guidance are further arranged on the main mounting block. The pulley assembly with the jockey pulleys is simple in structure, convenient to mount and capable of effectively eliminating sliding gaps.

Description

【Technical field】 [0001] The invention relates to a pulley assembly. 【Background technique】 [0002] Existing door leaf generally all is hoisted in the guide rail groove when guide slide is installed, and guide rail is provided with guide rail in the guide rail groove, slides on guide rail by pulley assembly. The existing pulley assembly generally only plays the role of load-bearing and sliding guide. Since the size alignment of the pulley assembly is not necessarily accurate after installation, as long as there is a little gap, the pulley assembly is easy to shake when sliding, so that the door leaf is easy to shake when moving , generating noise and bringing certain safety hazards. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a pulley assembly with auxiliary wheels that has a simple structure and can effectively eliminate gaps. [0004] In order to solve the above problems, the present...
