Description

Technical Field

[0001] The present application relates to the technical field of treadmills, and in particular to a treadmill folding mechanism and a treadmill. Background Art

[0002] With the improvement of people's living standards and the promotion of national fitness, users have an increasing demand for treadmills. There are many types of treadmills, among which foldable treadmills are more suitable for indoor use. They occupy less space and are deeply loved by users.

[0003] For example, the patent document with publication number CN220142527U proposed by the present applicant proposes a treadmill armrest folding mechanism and a treadmill, which can realize effective folding of the armrest.

[0004] However, for some treadmills that integrate the display screen support and the handrail, there is no good folding mechanism. Therefore, how to achieve the folding of such treadmills and simplify the folding action is the purpose of this application.

[0005] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0006] Based on this, the present application provides a treadmill folding mechanism and a treadmill to solve one of the above-mentioned technical problems.

[0007] The technical solution adopted by the present application to solve its technical problems is to include: a column; a limiting member, whose bottom end is fixedly arranged in the column, a limiting groove is arranged on one side of the column, and a first rotating shaft is arranged on the other side; a support arm, which is rotatably arranged on the limiting member through the first rotating shaft, and a tension spring fixing part is fixedly arranged at the bottom end; a movable locking member, on which a second rotating shaft is arranged, which is rotatably connected with the support arm through the second rotating shaft, a handle is fixedly arranged at the bottom end of one side, and a tension spring movable part is arranged at the bottom end of the other side, and a tension spring is arranged between the tension spring movable part and the tension spring fixing part; when the tension spring movable part enters the limiting groove, the support arm is limited to achieve the expansion and locking of the support arm; by pressing the handle to make the tension spring movable part disengage from the limiting groove, the support arm can be rotated along the first rotating shaft to achieve the folding of the support arm.

[0008] In some embodiments, the limiting member further includes a limiting rod, and the limiting rod is arranged above the first rotation axis.

[0009] In some embodiments, the limiting member is provided with a U-shaped groove that cooperates with the second rotating shaft.

[0010] In some embodiments, the limiting groove is square, the tension spring movable part is a square shaft that cooperates with the limiting groove, and a fitting groove is formed in the middle of the square shaft for fixing the end of the tension spring.

[0011] In some embodiments, when the support arm is in the deployed and locked state, there is a spacing between the handle and the support arm, and the movable locking member is rotated by pressing the handle to reduce the spacing.

[0012] In some embodiments, the inside of the column is hollow and the limiting member is fixedly arranged inside the column by screws.

[0013] In some embodiments, the limiting member includes two sheet bodies symmetrically arranged on both sides of the support arm.

[0014] On the other hand, the present application provides a treadmill, which includes the treadmill folding mechanism shown in any of the above embodiments; wherein, the columns are rotatably arranged at both ends of the treadmill running platform, and a console is arranged between the folding mechanisms on the two columns.

[0015] In some embodiments, a rotation knob is arranged at the lower end of the column to fix the column.

[0016] The beneficial effect of the present application is that when the mechanism needs to be folded, only by pressing the handle, the movable locking member will start to rotate along the second rotation axis, driving the tension spring movable part to leave the limiting groove, and the support arm can move freely, thereby making the console also enter the rotating state and rotating to an angle approaching parallel to the column. At this time, only by rotating the rotation knob, the column can also be in the folded state, and the operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
