Description

Technical Field

[0001] This utility model relates to the field of freezer technology, specifically to a freezer door limiting structure. Background Technology

[0002] In modern society, freezers, as refrigeration equipment capable of low-temperature storage, are widely used in various fields such as commerce, homes, medicine, and scientific research. Currently, freezers often lack effective door fixation after opening, requiring continuous support during item retrieval and reducing their effectiveness. Therefore, a limiting mechanism is needed to effectively restrict the door's movement. For example, patent document CN223020670U discloses a freezer door limiting structure. This structure, through the inclusion of a fastening device and a resetting device, allows for door opening. When the lid is rotated, the lid causes a rod to abut against a baffle, which moves backward under pressure. At this point, a cylinder activates, driving a telescopic rod to insert into the baffle, thus positioning the lid and allowing item retrieval. After retrieval, the cylinder moves the telescopic rod away from the baffle, and rotating the lid causes the rod to disengage from the baffle. The baffle, now free of restraint, is then repositioned by a spring that compresses it.

[0003] When the freezer door is disengaged from the limit switch, the cylinder needs to be operated, which increases the consumption of external energy. At the same time, it is not easy for users who are not familiar with the freezer to control the cylinder, thus reducing the effectiveness of the freezer. Summary of the Invention

A card plate is fixedly provided on the top of the cabinet door, and the lower end of the card plate is engaged with the limiting block.

[0008] A guide support mechanism for supporting the lateral movement of the limiting block is provided between the limiting block and the support frame;

[0009] The card plate is hollow inside, and a sliding hole is opened on the upper side of the end near the limiting block. A push block slides through the sliding hole and is configured to cooperate with the limiting block.
