Abstract

An improved lifting folding mechanism of the running machine, consisting of a lifting mechanism and a folding mechanism, both of which are arranged between the frame body of the running machine and the running platform. The frame body has two lateral bars facing each other. The lifting mechanism has a telescopic bar, one end of which is pivoted in the middle part of the cross bar of the frame body and the other end of which is pivoted in the middle part of the front of the running platform, and two lifting bars, one ends of which are seperately pivoted on both sides of the front end of the frame body and the other ends of which are pivoted on both sides of the front end of the running platform. The folding mechanism has at least one folding bar, one end of which is seperately pivoted on both sides of the front end of the running platform and the other end is slidingly arranged as a bar body in the chute of the lateral bar of the frame body, and a buckle component, which is a cross bar pivoted on the frame body. Using electricity, the utiliy model makes it possible for the height of the front end of the running platform to be adjusted by lifting and also makes the back end of the running platform to be folded upwards. Without the use of human labor, the lifting of the running platform can be operated, and also the effect of simple-folding and energy-saving can be achieved.

Description

Improved treadmill elevating folding mechanism

Technical field

The utility model relates to a kind of health and fitness facilities, relates in particular to a kind ofly to operate running platform lifting and folding simple improved treadmill elevating folding mechanism in electronic mode.

Background technology

See also shown in Figure 8, existing a kind of Foldable running apparatus with the function of rising, it is to set up a pedestal 6 on a support body 5, the crawler belt 62 that winding one is driven by one first motor 61 in this pedestal 6, articulate a connection piece 63 between these pedestal 6 front ends and this support body 5 front ends, the bottom of this pedestal 6 sets firmly a straight line brake 7, this straight line brake 7 has an expansion link 72 by one second driven by motor, one end of this expansion link 72 is fixedly arranged on the bottom of this pedestal 6, the other end then articulates the part 8 that rises, the both sides of this part 8 that rises are articulated in the both sides of these pedestal 6 front ends respectively, and this part 8 that rises is respectively equipped with a roller 81 in the both sides of an end of pivot joint relatively.Whereby, when 72 elongations of this expansion link, this part 8 of rising is fulcrum and swing supports to arrive in ground this roller 81 with the articulated section, and then raises the height of pedestal 6 front ends.If in the time of will making the rear end of this pedestal 6 folding, be the rear end of pedestal 6 is upwards folding with manpower, as shown in Figure 9, with the volume of reduction treadmill, and convenient collection.

Because the pedestal 6 of this treadmill is upwards folding during collection, the rear end of this pedestal 6 in manual mode, is upwards lifted and drawn close forward, make this pedestal 6 collapsible, convenient collection with the reduction volume.Yet this pedestal 6 itself has certain weight, and the pedestal of especially large-scale treadmill is quite heavy, and for women or more small and weak user, the strength of depending merely on hand is difficult for pedestal 6 upwards folding, causes this pedestal 6 being difficult for when folding.

Moreover, after this pedestal 6 is folding, and none fixing structure plays fixation to this position, pedestal 6 folding back, therefore when this pedestal 6 is collided by external force, promptly topple over downwards suddenly the rear end that pedestal 6 is upwards lifted, and cause pedestal 6 colliding surfaces to send loud noise even damage.More dangerous is, the platform of toppling over downwards suddenly might strike the user, and accident meets accident.

In addition, because when these pedestal 6 front ends rise, it is position by this part 8 that rises of length restriction of this expansion link 72, and this expansion link 72 is fixed in the bottom of this pedestal 6, and the active force that makes this pedestal 6 drops on this expansion link 72 fully and rises the articulated section of part 8, and can't have a firm support, might be because of violent running action, cause bursting apart of this articulated section, and cause danger.
