Description

Pulling assembly for drawer type door

The present application claims the priority of the Chinese patent application entitled "Drawing Assembly for Drawer Doors" on March 16, 2017, the application number is 201710158946.4, the entire contents of which are incorporated herein by reference. In the application.

Technical field

The present invention relates to the field of refrigeration equipment, and in particular to a drawer assembly for a drawer type door.

Background technique

At present, the storage volume requirement of the refrigerator is getting larger and larger, and the shape of the refrigerator is obviously increased. In this case, the drawer type door assembly for the refrigerator is more likely to be stuck during the pulling and closing process due to uneven force on the left and right slide rails. It has been disclosed in the industry that a synchronous link is arranged at the rear end of the left and right slide rails to enhance the synchronization of the left and right slide rails, avoiding the occurrence of jamming during the drawing process, and even causing damage to the pull assembly.

However, the existing synchronous connecting rods are mostly integrated with the left and right sliding rails, and some refrigerator products are placed on the rear side of the drawer type door body, so that the items to be stored can be directly directly taken out when the drawer is taken out. Place on the shelf to increase the volume usage of the refrigerator. At this time, the synchronizing link fixed on the left and right sliding rails will affect the storage of the articles, and will seriously collide with the articles on the shelf when the door body is pulled. Chinese Patent No. CN 155 155 839 A discloses a drawing assembly and a refrigerator, and specifically discloses a connecting rod detachably mounted on the left and right sliding rails, but it does not disclose the assembling structure of the connecting rod and the sliding rail. Moreover, due to the serious stress and friction of the connecting rod during the drawing process of the drawer type door body, the traditional clamping method makes the connecting rod easy to wear, affecting the working stability and the synchronization performance of the sliding rail.
