Description

Handstand machine with device for adjusting height by moving outer tube

Technical Field

The invention relates to fitness equipment, in particular to a handstand machine.

Background

A general handstand machine generally includes an handstand mechanism which can be turned backward, a rear leg clamping mechanism which is fixed to a rear side of the handstand mechanism, and a front leg clamping mechanism which is rotatably controlled to be provided to a front side of the handstand mechanism. When the foot stand is used, a user usually stands on the pedal of the handstand mechanism, pivots the front foot clamping mechanism backwards to clamp the feet together with the rear foot clamping mechanism, and then locks the front foot clamping mechanism. At this time, the user can invert the inversion mechanism to an inverted state to perform inversion.

In the handstand state, the human body is mainly held by the user's instep and the front leg-clamping mechanism and is fixed on the handstand machine, so that the weight of the human body is borne by the front leg-clamping mechanism. However, since the front leg clamping mechanism includes a pivotal component and a movable structure, there is an assembly gap when assembling each component, and when the user operates in an inverted posture, the user's foot back is supported against the movable front leg clamping structure, and when the weight of the human body is concentrated on the front leg clamping set, the assembly gap of each component causes the user to instantly generate an unsafe feeling of shaking.

However, when the length of the existing handstand machine on the market is usually adjusted according to the heights of different people, the adjusting method is too complicated and the fixing effect is poor, so that the overall using effect is reduced.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a handstand machine which is safe, reliable and wide in application range.

An inversion machine with an outer tube moving height adjusting device, comprising:

a main support body;

an auxiliary handstand mechanism, including an auxiliary handstand unit, including a back support member set and an extension member set, the back support member set is pivotally assembled on the main support body, the extension member set is connected to the back support member set and extends downwards along a length direction; the front clamping foot set is fixed and cannot be arranged at the bottom side of the auxiliary handstand unit in a pivot way, the rear clamping foot set is assembled at the bottom side of the auxiliary handstand unit in a pivot way, and the rotating axis is a fulcrum to drive the rear clamping foot set to move towards the front clamping foot set in a pivot way; the extending member set further comprises an inner pipe, an outer pipe, a fixing component and a pedal, wherein the inner pipe is immovably and fixedly connected to the bottom side of the back support member set, the outer pipe is movably sleeved outside the inner pipe, and the pedal is fixedly arranged on the outer pipe; and

and the control unit comprises a control group, and the control group is arranged on the outer pipe element and can be operatively connected with the front clamping leg group.

The invention has the following effects:

(1) Because the front clamping foot group is fixed and has no pivot structure relative to the auxiliary inverted unit, the pivot structure of the invention is designed on the rear clamping foot group, so that under the action that the auxiliary inverted mechanism turns or pivots to be in an inverted posture, the weight of a human body is supported on the fixed front clamping foot group instead of the front clamping foot group comprising a pivot or movable structure, and the assembly clearance of each part is reduced, so that a user can instantly generate a shaking unsafe feeling;

(2) When the length is adjusted according to the heights of different people, the adjusting method is simple and convenient, and the overall using effect is improved.
