Abstract

The invention provides a connecting structure of sliding-rail synchronous gears, aiming to solve the problem that synchronous gears cannot be guaranteed to rotate with a connecting shaft synchronously in an existing structure and guaranteeing smooth sliding of a drawer. The connecting structure comprises two parallel mounted rack sliding rails, two synchronous gears and a connecting shaft. The two synchronous gears are mounted on the two rack sliding rails respectively and are connected with the two rack sliding rails in a teeth-shaped meshing manner. The two synchronous gears are connected through the connecting shaft. The connecting structure is characterized in that one connecting shaft hole is reserved on each synchronous gear, teeth-shaped grooves are reserved on the periphery of the connecting shaft holes, positioning teeth matched with the teeth-shaped grooves of the connecting shaft holes are arranged on the outer circumference of the connecting shaft, and the positioning teeth of the connecting shaft holes can be mounted with the teeth-shaped grooves of the connecting shaft in a clearance manner directly.

Description

technical field [0001] The invention relates to the field of slide rail structures for household appliances, in particular to the field of slide rail structures for large-capacity refrigerators, in particular to the connection structure of slide rail synchronous wheels. Background technique [0002] Generally, due to the large horizontal and horizontal spacing of large-capacity refrigerators, in order to ensure that the refrigerator drawer can be pulled smoothly, usually a synchronous slide rail mechanism is installed along the longitudinal pull direction at the horizontal and horizontal ends of the lower part of the drawer. The synchronous rack slide rail 1 installed in parallel direction, the two synchronous gears 8 installed in the drawer are meshed with the synchronous rack slide rail 1, see figure 1 A connecting shaft 9 is also installed between the two synchronous gears 8 to ensure that the gears 8 at both ends can be synchronously meshed and rotated on the respective ...
