Description
Technical field
The utility model relates to a kind of treadmill, and is particularly a kind of by improving the treadmill that lifting structure obtains firm support.
Background technology
General treadmill is to make the runner that better running effect be arranged, and the running platform front end that how can be designed to treadmill can lifting, thereby changes the gradient of running platform and increase movement effects.As shown in Figure 9, this is a kind of treadmill running framework high-low regulating commonly used, it mainly is to link on the sheet 7 two, be provided with a framework pivot hole 71, a front strut pivot hole 72 and a long shaft-pivot hole 73 according to high and low and front and back position respectively, wherein, framework pivot hole 71 and front strut pivot hole 72 lay respectively at the higher position of front end and central authorities that links sheet 7, and the position of long shaft-pivot hole 73 then is positioned at and links sheet 7 rear ends and lower position.Therefore, this binding sheet 7 utilizes framework pivot hole 71 to be hubbed at the front end J both sides of running framework 6 respectively, utilizing front strut pivot hole 72 to be pivoted with front strut 5 again combines, then, in the long shaft-pivot hole 73 of two binding sheets 7, place a long shaft rod 731 again, the guiding mechanism 8 that on long shaft rod 731, is pivoted again at last, and the manipulation end of this guiding mechanism 8 is crossed out to the front end of running framework 6, and be located on the spacer 51 of front strut 5; That utilizes guiding mechanism 8 controls part so that during its pulling screw rod 81 displacement forward or backward, thereupon long shaft rod 731 synchronous shift of drawing.At this moment, linking sheet 7 will serve as that axle produces the effect of moving of revolving with the position in front strut pivot hole 72, and then running framework 6 is moved with the high and low accent of 71 positions, framework pivot hole and change it and prop up angle, thereby make this running framework 6 liftings.
Because this running framework 6 is to link sheet 7 with two to articulate with front strut 5, and with the pulling screw rod 81 of this guiding mechanism 8 is flexible should running framework 6 with lifting, therefore weight that should running framework 6 carried and the strength that produces when running link sheets 7 by two and are born, the strength that two binding sheets 7 are born is then supported by the pulling screw rod 81 of this guiding mechanism 8, this pulling screw rod 81 extends the longest when minimum when running framework 6 is reduced to, can on pulling screw rod 81, produce bending stress, and cause the wearing and tearing of this pulling screw rod 81.Though the pulling screw rod 81 of this guiding mechanism 8 is arranged with an external member 82 51 of two spacers, can appropriateness slow down the stressed of pulling screw rod 81, but the bending stress for this pulling screw rod 81 does not still have too big help, and this external member 82 even can interfere with the rotation of this pulling screw rod 81.
Moreover, because running framework 6 is serve as a lifting with the front strut pivot hole 72 that links sheet 7, for making these running pivot frame 6 front ends be increased to certain altitude, the distance that the front strut pivot hole 72 of this binding sheet 7 and framework pivot hole are 71 will have certain-length, can cause the arm of force h1 in 71 in the front strut pivot hole 72 of this binding sheet 7 and framework pivot hole long thus, when running framework 6 serves as when axially going up folding, as shown in figure 10 with this framework pivot hole 71.Long arm of force h1 can increase front strut pivot hole 72 stressed of this binding sheet 7, makes the support force after these running framework 6 foldings not good, the running framework 6 after can't the firm support folding.
Summary of the invention
Main purpose of the present utility model is to provide a kind of by improving the treadmill that lifting structure obtains firm support at above-mentioned problem.
Another purpose of the present utility model be the rear end of this running platform with two lift components and base support arm articulated section serve as axially on during folding, first end that this two lift component and this running platform articulate is pivot pendulum upwards thereupon also, this lift component and this support arm are articulated, and make and this running platform arm of force between articulating shortens, thereby can firm support live running platform after the folding.
For achieving the above object, the utility model adopts following technical proposals:
Described treadmill sets up a running platform at two arm rooms of a base, the front bottom end of this running platform has at least one block, and this lowering or hoisting gear has lift component and an expansion link of two symmetries, and each lift component has form an angle outward extending first end and second end.Each lift component is articulated in the medial surface of each support arm of this base near the bottom respectively with the center of relative first end and second end, first end of each lift component is articulated in the both sides of running platform front end respectively, be installed with a cross bar between second end of each lift component, this cross bar is positioned at the bottom of running platform front end, for the block of this running platform against, one end of this expansion link is articulated in a side of this cross bar, and the other end of this expansion link is articulated in the bottom of this running platform.Because this running platform front bottom end is provided with two blocks.This block can be resisted against on the cross bar of this lift component when running platform drops to the end, to support running platform, the strength that makes the weight that this running platform carries and produce when running is shared by this cross bar, thereby the bending stress that this expansion link is produced minimizes, and makes this expansion link not easy to wear.
Treadmill structure described in the utility model is firm, and parts are not easy to wear, thereby durable in use.
