Description

Technical Field

[0001] The utility model relates to a linear track supported adjustable device and a multifunctional adjustable stool, belonging to the field of fitness equipment. Background Art

[0002] With the popularization of fitness culture and the diversification of fitness needs, the functionality and convenience of fitness equipment have become the focus of research and development. Among many fitness equipment, adjustable training stools are widely popular because they can adapt to different training needs. The design and function of training stools directly affect the training effect and the user experience.

[0003] At present, the following several support and adjustment methods are mainly adopted for adjustable training stools on the market:

[0004] Arc iron plate support, pin-fixed type: This design provides support through an arc iron plate and fixes the angle of the training stool through pins. However, this design may not be flexible enough during adjustment, and the pin-fixed method may lead to insufficient stability, especially during high-intensity training.

[0005] Straight iron plate / iron pipe support, card slot fixed holes: This type of training stool uses a straight iron plate or iron pipe as the support structure and adjusts the angle through card slots and fixed holes. Although this method provides a certain degree of adjustability, the design of card slots and holes may result in insufficiently fine adjustment, and wear may occur after long-term use, affecting the stability and durability of the training stool.

[0006] Telescopic tube for height adjustment: Some training stools use telescopic tubes to adjust the height of the seat cushion or backrest cushion to adapt to the height of different users and training needs. Although telescopic tubes are convenient, they may slide during the adjustment process, affecting the stability of the training stool. Content of the Utility Model
