Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to an off-axis connecting mechanism and a drying device using the same. Background Technology

[0002] Floor-standing clothes drying racks are one of the most popular drying devices on the market. Their structure mainly consists of horizontal drying rods and vertical support rods or support frames.

[0003] Currently, the most common floor-standing clothes racks on the market can be categorized by their side shape into X-shaped, herringbone, inverted Y-shaped, wing-shaped, and H-shaped; and by the number of support rods, they can be divided into single-rod, double-rod, and multi-rod types.

[0004] As shown in existing patent documents such as CN206219858U and CN308582372S, existing X-shaped drying racks generally consist of horizontal drying rods and X-shaped connecting frames. Since the two rods that make up the X-shaped connecting frame are coaxially hinged, similar to scissor frames, they interfere with each other when folding, making the folding process not smooth. The existing methods basically use segmented rod structures to solve the problem of mutual interference. Although this can make the two rods parallel to each other when folded, reducing space occupation, the height of the X-shaped connecting frame cannot be adjusted. Even in the fully folded state, the space occupied in the height direction is still large, indicating room for improvement. Utility Model Content

When the extension and retraction adjustment is in place, the elastic element pops out and cooperates with the gear holes to achieve locking.

[0054] The advantages of the off-axis connection mechanism of this utility model compared with the traditional structure are as follows:

[0055] 1. This utility model provides a novel off-axis connecting mechanism. The intersection point of the first rod-shaped member 1 and the second rod-shaped member 2, and the central hinge point of the first connecting plate 3 and the second connecting plate 4 are not at the same position. That is, the first rod-shaped member 1 and the second rod-shaped member 2 are offset from the central axis 5 of the first connecting plate 3 and the second connecting plate 4. The advantage of this is that, during folding, the first rod-shaped member 1 and the second rod-shaped member 2 will not interfere with each other, thus achieving a completely parallel state in the folded state, significantly saving space. A pair of mounting parts enables the rod-shaped load-bearing member to cooperate with external mounting surfaces such as walls, achieving installation and fixation without drilling or using screws or other fasteners.

[0056] 2. Due to the off-axis design of the first rod 1 and the second rod 2, the first rod 1 and the second rod 2 of this utility model can adopt a telescopic sleeve structure. The advantage of this is that the height of the first rod 1 and the second rod 2 is adjustable, and the space occupied in the height direction can be further reduced after folding, making it convenient to use and store.

The X-shaped connecting frame b is the aforementioned off-axis connecting mechanism. The upper ends of the first rod-shaped member 1 and the second rod-shaped member 2 are connected to the horizontal drying rod a.

[0059] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
