Abstract

The invention discloses a space walker with a damping rotating shaft, which comprises a handrail, a damping rotating shaft, a column, a connecting rod, a foot switch and a pedal. The column is fixed on the ground, the damping shaft is fixed on the column, the damping shaft is connected with the pedal through the connecting rod, the foot switch is fixed on the pedal, the foot switch controls the connection and disconnection of the power supply of the damping shaft, and both sides of the handrail are connected with the column. In the present invention, a damping shaft is added at the rotating shaft. The damping shaft is an electromagnetic damping shaft with a built-in power supply. The connection and disconnection of the power supply of the damping shaft is controlled by a foot switch. When the power supply of the damping shaft is disconnected, the use of the spacewalker is not affected. , After the damping shaft is opened, the damping effect is generated to slow down the movement of the pedal and increase the safety.

Description

Space walker with damping rotating shaft

Technical Field

The invention relates to the field of fitness equipment, in particular to a damping type space walker.

Background

The spacewalk machine is common fitness equipment in daily life, is widely distributed in public areas such as park squares, can effectively exercise the balance ability and hand and foot coordination ability of people, has strong interest and fitness function, and is particularly popular with children and the old.

The existing space walker which is widely used is poor in safety, feet are easy to separate from a pedal in the using process, the pedal is large in inertia and not easy to stop, and accidents of falling and collision can happen, so that the existing space walker needs to be improved, and the rapid movement of the pedal under unexpected conditions is limited. According to the invention, the switch is arranged at the pedal, when the pedal switch is not under the action of pressure, the switch is in an on state, and at the moment, the damping rotating shaft of the space walker plays a damping role to limit the rapid movement of the pedal of the space walker; when the pedal switch is under the action of pressure, the switch is in a closed state, the damping rotating shaft of the space walker is the same as the normal rotating shaft, and the movement of the pedal is not limited. On the premise of not influencing the normal use of the spacewalk machine, the safety of the spacewalk machine is greatly improved, and the probability of collision and wrestling accidents is reduced.

Disclosure of Invention

The invention mainly solves the technical problem of providing a spacewalk machine with a damping rotating shaft, which can protect a user from being injured as much as possible under the condition of not influencing normal use.

In order to solve the technical problems, the invention adopts a technical scheme that:

a spacewalk machine with a damping rotating shaft comprises an armrest 1, the damping rotating shaft a2, a damping rotating shaft b3, a column a4, a column b5, a connecting rod a6, a connecting rod b7, a foot switch a8, a foot switch b9, a pedal a10 and a pedal b 11.

The upright post a (4) and the upright post b (5) are fixed on the ground in a conventional fixing mode, two ends of the handrail 1 are respectively connected with the upright post a4 and the upright post b5, the pedal a10 is connected with the damping rotating shaft b3 through the connecting rod a6, and the pedal b11 is connected with the damping rotating shaft a2 through the connecting rod b 7; the foot switch a8 and the damping rotating shaft b3 are connected through a lead, and the foot switch b9 and the damping rotating shaft a2 are connected through a lead; the foot switch a8 is fixed on the pedal a10 by screws, and the foot switch b9 is fixed on the pedal b11 by screws, which are fixed in a conventional manner and will not be described herein.

The damping rotating shaft a2 and the damping rotating shaft b3 are electromagnetic damping rotating shafts and are provided with built-in power supplies; the damping rotating shaft a2 is controlled by the foot switch b9 to connect and disconnect the power supply, and the damping rotating shaft b3 is controlled by the foot switch a8 to connect and disconnect the power supply.

When the space walker is in a natural state, the foot switch a8 and the foot switch b9 are in an open state, the damping rotating shaft a2 and the damping rotating shaft b3 have a damping effect and work normally, and the pedal a10 and the pedal b11 are not easy to swing due to the damping effect.

When the space walker is normally used, a person steps on the pedal a10 and the pedal b11, the pedal a8 and the pedal b9 sink under the action of gravity, the power supply of the damping rotating shaft a2 and the power supply of the damping rotating shaft b3 are disconnected, the damping rotating shaft a2 and the damping rotating shaft b3 do not generate a damping effect, the space walker is in the same use condition as the space walker under the normal condition, and the swinging of the pedal a10 and the pedal b11 is not damped.

When the space walker leaves the pedal a10, the foot switch a8 is reset immediately, and the damping rotating shaft b3 works normally; when the foot leaves the pedal b11, the foot switch b9 is reset immediately, and the damping rotating shaft a2 works normally. After the damping rotating shaft works normally, the pedal is subjected to the resistance of the damping rotating shaft through the connecting rod, so that the pedal stops slowly and does not swing to a large extent, and a user is prevented from being injured.

The invention has the beneficial effects that:

compared with the conventional space walker, the space walker with the damping rotating shaft is additionally provided with the damping rotating shaft, and the damping rotating shaft is in a closed state under normal conditions; when the space walker is normally used, the damping effect is removed, and the normal use of the space walker is not influenced; after the use, when the foot leaves the pedal, the damping rotating shaft starts to work, so that the pedal which moves quickly can be stopped slowly, the damage caused by the error operation of the space walker can be effectively reduced, and the safety of the space walker in use is improved.
