Description

A quick-folding structure for a flat treadmill Technical Field

[0001] This utility model belongs to the field of treadmill technology, and in particular relates to a structure for quick folding of a flat treadmill. Background Technology

[0002] As an indoor running exercise equipment, a treadmill consists of a running platform and a monitor frame. For portable treadmills, the location needs to be changed frequently depending on the fitness venue, so they need to be transported or stored repeatedly. The monitor frame, which is perpendicular to the running platform, makes the entire treadmill take up a lot of space, making transportation and storage very inconvenient. Furthermore, if the two sides of the monitor frame are rotated and installed on the two sides of the running platform, when unfolding, the two side frames of the monitor frame need to be fixed to the two sides of the running platform, and when folding and storing, the two side frames of the monitor frame need to be locked to the two sides of the running platform again. This folding and unfolding method is inefficient, cannot be folded and unfolded quickly, and is time-consuming and laborious.

[0003] To address these issues, we provide a quick-folding structure for a flat treadmill. Summary of the Invention

[0004] The purpose of this invention is to provide a quick-folding structure for a flat treadmill. This is achieved by rotating and mounting the two side frames of the display head frame to the sides of the running platform, and installing folding components on both sides of the running platform. These folding components are connected to the side frames of the display head frame via a transmission mechanism. When unfolding is required, the display head frame is folded upwards, and the folding components lock the display head frame to the running platform, preventing it from wobbling after unfolding. Furthermore, push-release components are installed on the two side frames of the display head frame and are connected to the folding components on both sides. When the treadmill needs to be stored, pressing the push-release components unlocks the folding components on both sides, and then folding the display head frame downwards, achieving quick folding. This reduces the space occupied by the display head frame and the running platform, facilitating storage and transportation.
