Description

Slope adjusting structure of treadmill

Technical Field

The utility model relates to a treadmill, especially a slope adjustment structure of treadmill.

Background

The electric treadmill is a common fitness equipment, and the electric treadmill drives the running belt through the motor to enable a person to walk or run on the electric treadmill at different speeds, thereby achieving good indoor exercise effect. For being closer to the natural environment of outdoor running and improving the body-building effect, people design a slope treadmill which can adjust the inclination angle of the running belt. The advent of such a treadmill with a gradient is very popular with users, but has the following drawbacks:

1. the device for adjusting the gradient is relatively complex in structure and large in size.

2. The integral lifting of the front end part needs larger power and the stability is not enough.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a structure is adjusted to slope of treadmill, simple structure, it is small, owing to adopted screw thread screw rod rotating-structure, the power of required motor is little, and the mechanical stability of slope is good.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a slope adjustment structure of treadmill, includes and runs platform and base, and the front end of running the platform passes through the front axle and base is articulated, and the left and right sides of running the platform rear portion all is equipped with slope adjustment structure, slope adjustment structure includes fore-stock and after-poppet, the rear end of fore-stock passes through hinge A with the front end of after-poppet and articulates, be equipped with supporting roller on the hinge A, the front end of fore-stock articulates in running the platform, and the rear end of after-poppet articulates in screw nut, screw nut spiro union is on by motor drive's lead screw, the lead screw adopts the bearing frame to fix on running the platform.

The treadmill comprises a left longitudinal beam and a right longitudinal beam, and the slope adjusting structures on the left side and the right side are respectively arranged on the inner side of the left longitudinal beam and the inner side of the right longitudinal beam.

The screw nut is provided with a hinge shaft B which extends outwards, the rear end of the rear support is hinged to the hinge shaft B, and the outer end of the hinge shaft B is positioned in a sliding groove of the left longitudinal beam or the right longitudinal beam.

And a rotating shaft of the motor is rotatably connected with the lead screw through a coupler.

Compared with the prior art, the beneficial effects of the utility model are that: by adopting the technical scheme, the motor drives the screw rod to rotate forwards and backwards through forward and backward rotation, so that the screw rod nut can be driven to move forwards and backwards along the screw rod, the front support and the rear support are contracted and extended, and the rear end of the running table is lifted and lowered. Simple structure, small, because of having adopted screw thread screw rod rotating-structure, the power of required motor is little, and the mechanical stability of slope is good.

Detailed Description

In order to make the technical solution of the present invention clearer, the following describes the present invention in detail with reference to fig. 1 to 6. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

The utility model relates to a slope regulation structure of treadmill, including running platform 1 and base 2, run front axle 3 of 1 front end of platform and articulated with base 2 through front axle bearing frame 3-1, be equipped with the bearing that is used for supporting front axle 3 on the front axle bearing frame 3-1, the left and right sides at running platform 1 rear portion all is equipped with slope regulation structure, slope regulation structure includes fore-stock 4 and after-poppet 5, the rear end of fore-stock 4 is articulated through hinge A6 with the front end of after-poppet 5, be equipped with supporting roller 7 on the hinge A6, the front end of fore-stock 4 articulates in running platform 1, and the rear end of after-poppet 5 articulates in screw nut 8, screw nut 8 spiro union is on by motor 9 driven lead screw 10, lead screw 10 adopts bearing frame 11 to fix on running platform 1.

Preferably, the running platform 1 comprises a left longitudinal beam 1-1 and a right longitudinal beam 1-2, and the slope adjusting structures on the left side and the right side are respectively arranged on the inner side of the left longitudinal beam 1-1 and the inner side of the right longitudinal beam 1-2.

Preferably, the screw nut 8 has a hinge shaft B12 extending outwards, the rear end of the rear bracket 5 is hinged on the hinge shaft B12, the outer end of the hinge shaft B12 on the left side is located in the sliding groove 13 of the left longitudinal beam 1-1, and the outer end of the hinge shaft B12 on the right side is located in the sliding groove 13 of the right longitudinal beam 1-2, which has the advantages that: firstly, the screw nut 8 can be prevented from rotating along with the screw 10; and secondly, the rear support 5 is hinged on the hinge shaft B12, the force of the rear support acting on the hinge shaft B12 is counteracted by the sliding grooves 13 on two sides of the hinge shaft B12, and the sliding of the screw nut 8 along the screw rod 10 cannot be greatly influenced. And a rotating shaft of the motor 9 is rotatably connected with the lead screw 10 through a coupling 14.

The screw rod 10 is driven to rotate forwards and backwards through the forward rotation and the backward rotation of the motor 9, and the screw rod nut 8 is driven to move forwards and backwards along the screw rod 10, so that the front support and the rear support are contracted and extended, and the rear end of the running table 1 is lifted and lowered. In a particular application, two extreme limits may be defined by limit switches or other means: when the front support and the rear support are contracted to the shortest length, the running platform 1 is in a horizontal position at the moment, and the motor stops rotating; when the front and rear supports are extended to the longest, the running platform 1 is at the position with the largest gradient at the moment, and the motor stops rotating.
