Guide wheel height positioning structure of sliding door upper wheel set

Abstract

The invention discloses a guide wheel height positioning structure of a sliding door upper wheel set. The structure comprises a fixing clamp, an inner clamp is arranged in the fixing clamp, an upper wheel assembly is arranged in the inner clamp, a height adjusting structure is arranged at the front end of the upper wheel assembly, an adjusting screw in the height adjusting structure is rotated, the relative height between the inner clamp and the fixing clamp can be adjusted, and the guide wheel height is adjusted; a mounting plate is clamped in the inner clamp, a spring is arranged at the lower end of the mounting plate, one end of the spring is arranged in a clamping groove of the mounting plate in an ejecting manner, the other end of the spring is clamped on the bottom of the fixing clamp, the counter-acting force of the spring is used, the inner clamp is driven to move upwards all the time, and the upper wheel assembly makes tight contact with the upper guide rail all the time. Thestructure has the beneficial effects that the upper wheel assembly sinks and is positioned through a positioning column, and the phenomenon that during sliding door mounting, the upper wheel set disturbs mounting is avoided; the counter-acting force of a torsion spring is used, the inner clamp bears upward pressure all the time, the inner clamp moves upwards all the time, the upper wheel assemblymakes tight contact with an upper guide rail all the time, and the optimal use state is achieved.

Description

technical field [0001] The invention relates to a sliding door accessory, in particular to a guide wheel height positioning structure for an upper wheel set of a flat sliding door. Background technique [0002] At present, it is very common to manufacture and use glass sliding doors and room sliding doors. Sliding doors are also called flat sliding doors. Sliding doors are generally two door leaves, pulleys are installed above and below each door leaf, and aluminum alloy tracks are assembled on the top and bottom of the cabinet. The pulleys slide in the corresponding tracks, and the upper track mainly plays a role of sliding fit and The role of the guide, the lower track plays a load-bearing role. Existing flat sliding door pulley device structure on the market is very simple, need to hang on the upper wheel and buckle in the upper guide rail during installation, then lower wheel is installed. Wherein, because the space of upper wheel is limited, and is unfavorable for obs...
