Description

Technical Field

[0001] The utility model belongs to the field of turnover boxes, and in particular relates to a liquid outlet structure of a liquid turnover box. Background Art

[0002] Liquid turnover boxes are logistic tools used to transport liquids. They are usually equipped with drain ports to facilitate liquid extraction and to observe whether there is leakage. Since liquid turnover boxes require a high degree of sealing, a sealing plate needs to be installed at the drain port. Currently, there are usually two ways to seal the drain port. One is to install the sealing plate through a lock and a hinge. This method requires a cumbersome manual opening and closing process, and it is not convenient to extract liquid when the door is open. The other is to use a sliding sealing plate, which slides in the slide groove to open and close. The problem is that it is easy to get stuck in the slide groove, and it requires two hands to adjust the angle, and the opening and closing is not smooth.

[0003] The Chinese patent with the publication number CN214932026U discloses a liquid outlet structure of a liquid turnover box, including a fixed plate and a sliding plate, the fixed plate is provided with a liquid outlet hole, a positioning hole, a closing limit hole, a track guide hole and an opening limit hole, the sliding plate is a square plate, and a positioning column and a guide slide column in the same vertical line are provided near the left edge of the sliding plate, the positioning column is installed in the positioning hole, the guide slide column is installed in the closing limit hole, the fixed plate is installed on two support frames of the liquid outlet, and the sliding plate is fixed between the fixed plate and the panel of the liquid outlet. The novel structure is simple, the design is ingenious, and the operation is convenient. The entire opening and closing process is very smooth, and the operation can be completed with a single hand lifting action. However, the sliding plate in the application rotates on the fixed plate to seal the liquid outlet, and the sealing effect of the liquid outlet is low.

[0004] In view of this, the present utility model is proposed. Utility Model Content
