Abstract

The utility model relates to the modification of an electric raising structure of a treadmill, which is composed of a base, a tread platform, an H-shaped bracket, a raising motor, etc., wherein, the upper ends of both sides of the H-shaped bracket are pivoted on the inner sides of the base corresponding to supporting rods of both sides; the lower ends of both sides of the H-shaped bracket are pivoted on both sides of the tread platform; one end of the raising motor is pivoted on the front end of the tread platform and the other end is pivoted on a transversal bar in the middle of the H-shaped bracket. When the raising motor is started for running, the pivoting points of the upper ends of both of the two ends of the H-shaped bracket are used as positioning support points; the position that the other end is pivoted at the bottom of the tread platform is used as a moving point; thereby, the tread platform can tilt at an elevation angle corresponding to the horizontal plane.

Description

The electronic structural improvement that rises of treadmill

Technical field

The utility model relates to mechanical, and particularly a kind of electronic structural improvement that rises of treadmill mainly is the H shape support that is pivoted between base and running platform relative side, and the electric machine that rises that is pivoted between the cross bar of running platform and H shape support.

Background technology

As everyone knows, common treadmill comprises a base, and these base both sides have extended upward a support respectively, and each bracket bottom section is respectively equipped with a upright slide rail; One framework leading portion both sides are respectively equipped with a roller to each slide rail that should base, make this framework can slippage in base, be provided with the running band of a running usefulness in this framework, this running band be to be turned round by a motor-driven, and be pivoted with an expansion link on the framework, this expansion link is driven by a power source; One end of two swing arms is articulated in an articulated section of framework two sides respectively, and between the end that this two swing arm is relative with the articulated section articulates is to be connected with one, this two ends respectively have takes turns, and establishes a pin joint seat on this axle for being articulated with the expansion link that is hubbed at this framework; Though said structure has the function that rises automatically, but constitutional detail is too much, assemble comparatively consuming time; The maximum height that its structure can rise only can move to the slide rail peak of base at the roller of frame sides, it is very limited that its structure can be adjusted the angular range that rises of running platform; Moreover another maximum shortcoming of this structure is the moving slide rail of guide roller upper and lower limit displacement, its top there is no the backstop function, in case the electric motor starting expansion link too stretches, to make the roller slippage of running platform both sides go out slide rail, and cause making running platform that the danger that moment hits to tenesmus is arranged, influence operator's safety.

The utility model content

According to the purpose of this utility model, the shortcoming that exists at the structure that rises automatically of general common treadmill, a kind of electronic structural improvement that rises of treadmill is provided, make it have the general equivalent structure part of simplification, and be convenient to make, assemble, and more can improve the increase of angle adjustment scope that can rise of its running board, and have the user of assurance and be perfectly safe; Its structure is respectively the upper end of H shape support both sides to be hubbed on base both sides pole relative inner, H shape support both sides lower ending pivot is located at the running platform two bottom sides, one electric machine one end that rises is to be hubbed on the running platform front end, end is to be hubbed on the middle cross bar of H shape support in addition, when startup rises the motor start, can be the location fulcrum by articulated section, upper end, H shape support both sides, but other end is articulated in place, running platform bottom and is moving point, makes the relative horizontal plane of running platform be the oblique effect of angle lapping.

The specific embodiment

As accompanying drawing 1 to shown in the accompanying drawing 4, the utility model includes a base 10, one running platform 20, one H shape support 30 and an electric machine 40 etc. that rises, wherein, respectively end on a H shape support 30 both sides is hubbed on base 10 both sides poles 11 relative inner, lower end, H shape support 30 both sides is hubbed at running platform 20 two bottom sides again, one electric machine 40 1 ends that rise are hubbed on running platform 20 front ends, other end is hubbed on the cross bar 32 in the middle of the H shape support 30, when startup rises motor 41 starts, can be by articulated section, upper end, H shape support 30 both sides as the location fulcrum, but other end is articulated in place, running platform 20 bottoms and is moving point, can reach to adjust to make running platform 20 relative horizontal planes be the oblique function of angle lapping; H shape support 30 is formed by binding one cross bar 32 in the middle of the L shaped plate 31 of two symmetries, and the electric machine 40 that rises rotates with interlock one screw rod 42 by a motor 40 drive gear set, make a screwed pipe that screws mutually with screw rod 42 overlap 43 scalable starts, other is hubbed on running platform 20 front ends at the end that electric machine 40 is provided with gear train that rises, and another screwed pipe overlaps on the cross bar 32 that 43 ends are hubbed on H shape support 30; As shown in Figure 5, base 10 is positioned at one inboard, running platform 20 bottoms, L shaped plate 31 underside that are H shape support 30 sides are pivoted with a positioning rod 12, these backstay 12 1 terminations are provided with a pedal 121, the end below is formed with a draw-in groove 122 in addition, and the position is installed with a projection 21 in running platform 20 with respect to the homonymy front end of backstay 12, when folding running platform 20 when being erectility, the projection 21 that is positioned at front end can be by hook at draw-in groove 122, after guaranteeing that running platform 20 folds, reach a kind of strong fix state, and when desiring to put down running platform 20, can press down by pedal 121 ends of backstay 12.Make draw-in groove 122 break away from projection 21, can keep flat running platform 20 smoothly.

Claims

1, a kind of electronic structural improvement that rises of treadmill, it is to be made of institutes such as base, running platform, H shape support and the electric machines that rises, it is characterized in that: the upper end of H shape support both sides is hubbed on base front end both sides pole relative inner, and H shape support both sides lower ending pivot is located at the running platform two bottom sides; One electric machine one end that rises is hubbed on the running platform front end, and end is hubbed on the cross bar in the middle of the H shape support in addition; Make articulated section, H shape support both sides upper ends be the location fulcrum, end is articulated in place, running platform bottom and is moving point in addition, can form the relative horizontal plane of running platform and be that to press down angle lapping oblique.
