Abstract

The utility model relates to a belt pulley of running machine. The belt pulley is separately arranged at two ends of the running machine frame body, a thin layer less than 1 mm is coated on the surface of the belt pulley; a high friction surface is formed by the thin layer and the contacting surface of the belt pulley. The utility model has the advantages of withstanding voltage ability, deformation and better applicability.

Description

Treadlemill with movable endless band

Technical field

The utility model relates to a kind of Treadlemill with movable endless band, refers in particular to the Treadlemill with movable endless band that a kind of surface is coated with a floor height friction film.

Background technology

Treadmill is a kind of well known exercise and fitness equipment.As shown in Figure 1, treadmill has a support body 10, and support body 10 two ends are provided with belt wheel 20, is arranged with the belt body of trampling for the runner 11 on the belt wheel 20.Belt wheel 20 is generally metal circular tube, and if therefore the surface if will positively drive belt body 11 rolls, must possess preferable frictional force comparatively level and smooth without the processing processing.Existing settling mode is as follows:

1, as shown in Figure 2, directly working roll spends 21 to increase frictional force on belt wheel 20 surfaces, the shortcoming of this mode is that working roll spends 21 can destroy the out of roundness of belt wheels 20, so that can influence the smooth and easy of belt wheel 20 rotations, and may improve noise, shortens member service life, reduces the quality of product;

2, as shown in Figure 3, coat a rubber layer 22 to produce frictional force on belt wheel 20 surfaces, the shortcoming of this mode is that treadmill is accomplished to sell and often goes through between the operating period the very long storage stage making assembling, each position of treadmill obviously is in the state of maintaining static therebetween, because the belt wheel 20 at two ends has the power that necessarily supports, the rubber layer 22 of belt body 11 for a long time only the outside be squeezed, its pliability and elasticity can change so that produce distortion, and can't restore, can cause the conduction in the future using to have some setbacks equally.

Summary of the invention

The purpose of this utility model be to provide a kind of can be withstand voltage indeformable, running is smooth and easy, prolong member service life, improve the Treadlemill with movable endless band of product quality.

The purpose of this utility model realizes by following technological means: a kind of Treadlemill with movable endless band, group is located at treadmill support body two ends, be arranged with belt body on it, the belt wheel surface is coated with the thin layer of a layer thickness below 1mm, and thin layer and belt body contact-making surface are made high rubbing surface.

Advantage of the present utility model is: 1, the high rubbing surface thin layer that coated of the utility model mat belt wheel surface, can exempt the shortcoming that prior art working roll flower on belt wheel causes belt wheel to be out of shape, the out of roundness that can keep belt wheel, reach conduction drive smooth and easy, prolong member service life, improve the purpose of quality.

2, the thickness of thin layer of the present utility model is below 1mm, so the amount of its compressive deformation can ignore fully, therefore can reach withstand voltage indeformable, purpose that applicability is better.

The specific embodiment

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

As Fig. 1, Fig. 4 and shown in Figure 5, Treadlemill with movable endless band of the present utility model is located at treadmill support body 10 two ends for 20 groups, is arranged with belt body 11 on it.Belt wheel 20 surfaces are coated with the thin layer 30 of a layer thickness below 1mm, and thin layer 30 is made high rubbing surface 31 with belt body 11 contact-making surfaces.The high rubbing surface thin layer that belt wheel 20 surfaces are coated, can exempt the shortcoming that prior art working roll flower on belt wheel 20 causes belt wheel 20 to be out of shape, the out of roundness that can keep belt wheel 20, reach conduction drive smooth and easy, prolong member service life, improve the purpose of quality.The thickness of thin layer 30 of the present utility model is below 1mm, so the amount of its compressive deformation can ignore fully, therefore can reach withstand voltage indeformable, purpose that applicability is better.

Claims

1, a kind of Treadlemill with movable endless band, group is located at treadmill support body two ends, is arranged with belt body on it, and it is characterized in that: the belt wheel surface is coated with the thin layer of a layer thickness below 1mm, and thin layer and belt body contact-making surface are made high rubbing surface.
