Folding treadmill

Abstract

The invention discloses a folding treadmill which comprises a running platform; a column assembly; and a locking assembly. The locking assembly comprises a pull rod; a folding handle eccentrically and rotationally connected to one end part of the pull rod; two fixing parts arranged on the side edges of the running platform respectively and arranged on the pull rods in a sleeving mode; and two rotating parts connected to the ends of the two vertical pipes respectively and arranged on the pull rod in a sleeving mode, wherein anti-rotation parts are arranged in an abutting area of the fixing parts and the rotating parts, springs are arranged between the fixing parts and the rotating parts, when the folding handle acts on the rotating parts and the spring deforms, the rotating parts abut against the fixing parts to prevent the rotating parts from becoming effective, and when the springs reset, the rotating parts are separated from the fixing parts to prevent the rotating parts from becoming invalid. According to the folding treadmill, locking and unlocking states of the stand column assembly and the running platform are achieved through the locking assembly; the structure is simple, the number of components is small, operation is easy, linkage is more stable, and the service life is long; and by rotating the folding handle, one person can easily complete unlocking, folding or unfolding and locking actions.

Description

technical field [0001] The invention relates to the technical field of treadmills, in particular to a folding treadmill. Background technique [0002] Existing treadmills are generally all foldable, which is not only convenient for packaging and transportation, but also saves limited living space for users. For example, the Chinese invention patent (CN210278104U) discloses a one-button linkage folding mechanism for a treadmill, including a column assembly, a chassis assembly, a column sleeve, a rotating shaft seat, a positioning sleeve, a left pull rope, a right pull rope, a horizontal plate, Pull cord sliding seat and linkage rod; column assembly includes left column and right column, a column sleeve is installed at the lower end of left column and right column, and a positioning piece with positioning hole is formed on the outer peripheral surface of the column sleeve, and the bottom frame assembly Including the left frame and the right frame, a rotating shaft seat is ins...

AI Technical Summary

Problems solved by technology

However, it has the following defects: (1) The linkage folding structure is complex, there are many parts, and the specific implementation of locking and unlocking process is not stable; (2) When folding the column assembly, by pressing down the linkage The way) the free end, the middle end of the linkage rod pulls the other end of the left and right pull ropes at the same time, so that one end of the positioning pin installed in the positioning bushing on both sides exits the positioning hole. At this time, the spring is compressed, and the column sleeve The tube and the rotating shaft seat are released from the positioning, and the column assembly can be rotated and lowered to realize the folding of the treadmill. During the folding process, it must always act on the linkage lever to complete the lowering or unfolding of the column assembly. Two people are required to complete the folding operation. Average process effect, poor experience
