Description

Technical Field

[0001] The present invention belongs to the technical field of outdoor hammocks, and particularly relates to an adjustment mechanism for a hammock. Background Art

[0002] As a leisure product, hammocks are widely loved by outdoor enthusiasts and household users because of their portability and comfort. Most of the existing hammock adjustment mechanisms realize the expansion and contraction of the hammock frame by directly adjusting the position of metal telescopic pipe fittings. The limitations of this design are mainly reflected in several aspects: First, during the adjustment process, the inner pipe and the outer pipe are in direct contact. After long-term telescopic operation, the outer surface of the inner pipe is easily damaged due to friction, resulting in a scratched phenomenon. This not only affects the aesthetics of the product, but also may cause the feel to be jerky or even stuck during adjustment due to increased resistance. Second, the lack of effective anti-friction design causes the outer pipe and the inner pipe to wear rapidly during frequent telescopic movements, greatly shortening the service life of the hammock adjustment mechanism. Moreover, due to the lack of consideration of the application of wear-resistant materials, the durability and smoothness of the overall structure are greatly reduced.

[0003] In summary, the main disadvantages of the existing hammock adjustment mechanism are easy wear, easy scratching of the outer surface of the inner pipe, and jamming during telescopic operation. These deficiencies limit the use experience and service life of the hammock, and there is an urgent need for an innovative design to solve these problems. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions.
