Drawer-type refrigerator slide rail composite unit

Abstract

The invention discloses a guide rail assembly used with a drawer-type refrigerator, which belongs to a device for loading, supporting or withdrawing refrigerated articles of the refrigerator. The guide rail assembly comprises a supporting portion which is formed in a way that two side walls of a storage chamber are raised inwards, a lead guide rail shaped in correspondence to the supporting portion and fixed on the supporting portion, a movable guide rail movably arranged on the guide slide rail, parallel shafts each with two ends arranged on the movable slide rail, a plane portion which is arranged in the lower part of the supporting portion and has a planar structure at the front end of a bracing portion, toothed racks arranged in a certain distance on the bracing portion in the moving direction of a storage vessel, and two pinions which are respectively engaged with the toothed racks and arranged adjacently to the two ends of each parallel shaft. The inventive guide rail assembly for drawer-type refrigerators can ensure the pinion of the parallel shaft at the back of the vessel to be accurately engaged with the toothed rack, thereby allowing the vessel to move smoothly.

Description

technical field [0001] The invention relates to a device for loading, supporting or taking out refrigerated items of a refrigerator. More specifically, the invention is a guide rail assembly for guiding the door to move when the drawer door is opened and closed horizontally. Background technique [0002] Storage spaces such as a freezer compartment or a refrigerator compartment are formed inside the refrigerator, and these freezer compartments or refrigerator compartments are selectively opened and closed by doors. In addition, the refrigerator door is usually hingedly connected to one side of the refrigerator main body, and rotates toward the front of the refrigerator centering on the hinge shaft. For drawer-type refrigerators, the drawer can be pulled out forward.

AI Technical Summary

Problems solved by technology

This phenomenon can only be judged by the naked eye of the installation personnel whether the pinion 16 is accurately meshed with the corresponding teeth of the rack 6, and the number of teeth of the pinion is about 30, so it is difficult to see the misassembly of the pinion

[0013] If the pinion 16 fails to engage on the rack 6 accurately, when the container linked with the pinion 16 moves forwards and backwards, the container does not move smoothly at first, and finally cannot be fully opened to the extent required by the user. will stop moving in the middle

In addition, when a greater force is applied in this state, the pinion gear 16 may be damaged.
