Door body opening limiting mechanism for refrigerating box

Abstract

The invention discloses a door body opening limiting mechanism for a refrigerating box. The door body opening limiting mechanism comprises a steel wire rope and a sliding sleeve, wherein the sliding sleeve is pre-embedded in a box body and is arranged along a vertical direction, an opening at the upper part of the sliding sleeve is positioned at the top part of the box body, one end of the steel wire rope is fixedly connected with a door body, the other end of the steel wire rope is arranged in the sliding sleeve and is provided with a suspension block in a connection manner, and a fixing buckle which is used for limiting the suspension block from moving out is arranged at the position of the opening at the upper part of the sliding sleeve. When the door body is opened, the steel wire rope can be pulled by the door body, the suspension block can be driven to move upwards by the steel wire rope, the suspension block can stop moving when touching the fixing buckle, and at the moment, the door body is opened to a certain angle and is located by virtue of the steel wire rope; and when the door body is closed, the steel wire rope can move downwards under the action of the gravity of the suspension block, the steel wire rope can be tucked in the sliding sleeve, the use is very convenient, and space cannot be occupied.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a door opening limit mechanism for the refrigerator. Background technique [0002] Small refrigerated boxes on the market all adopt vertical door at present, promptly open the door in the front of refrigerated box. As we all know, the cold energy in the refrigerator runs downward. This method of opening the door is easy to lose the cold energy. Even if the door is not opened, it is easy to leak part of the cold energy at the door seal at the bottom of the refrigerator. [0003] Therefore, the requirements for refrigerators used to preserve tea leaves are relatively high. Traditional refrigerators cannot meet the requirements of keeping tea fresh for a long time. Therefore, it is necessary to develop a tea refrigerator with low cost and low cooling capacity. [0004] It is specially conceived to develop a refrigerator, which is to open the door on the top of the box, and the box is closed around...

Problems solved by technology

As we all know, the cold energy in the refrigerator runs downward. This method of opening the door is easy to lose the cold energy. Even if the door is not opened, part of the cold energy is easy to leak from the door seal at the bottom of the refrigerator.

[0003] Therefore, the requirements for refrigerators used to store tea are relatively high. Traditional refrigerators cannot meet the requirements of keeping tea fresh for a long time. Therefore, it is necessary to develop a tea refrigerator with low cost and low leakage of cooling capacity.

[0004] It is specially conceived to develop a refrigerator, which is to open the door on the top of the box, and the box is closed around, so that it is easy to save cold energy, but the angle of the upward opening door is not easy to fix, unlike the previous vertical door. , so if there is no limit mechanism, you need to hold it by hand or use the wall to locate it, which is very inconvenient
