Description

A kind of treadmill

Technical field

The utility model relates to a kind of fitness equipments, particularly relate to a kind of treadmill.

Background technique

With the continuous improvement of people's living standards, the rhythm of life is also getting faster, the seldom having time of people participates in family Outer exercise, therefore more and more people have selected indoor sports body-building.Capital equipment of the treadmill as indoor sports body-building, easily Operation, exercise effect are good, will be widely welcomed in family and gymnasium, people are also increasingly to increase for the demand of treadmill It is long.

As shown in Figures 1 to 4, be existing running machine structure, mainly include under(-)chassis 1A and with under(-)chassis 1A In the bracket 2A that vertical direction connects, the front axle and rear axle of treadmill are attached separately to the both ends of frame 1A, front roll 11A and rear rolling Cylinder (not illustrating in figure) respectively with bearing holder (housing, cover) on axle, run around on forward and backward roller by tread belt 12A tensioning Equipped with support running board under belt 12A, follower belt 13A is tightly packed on the driving wheel 14A of the side front roll 11A, electronic mechanical, electrical Source, control sensor, velocity sensor etc. are mounted on the front end of frame 1A, and treadmill handrail frame 21A is installed on the top of bracket 2A End, instrument control panel 22A are installed on arm-rest frame 21A.As shown in Figures 3 and 4, the treadmill under(-)chassis 1A peace of existing structure After the completion of dress, the upper surface of tread belt 12A is less than the top of driving wheel 14A, i.e. the upper surface of tread belt 12A is lower than The upper level of follower belt 13A, in this way, as shown in Fig. 2, the top of shell 15A can be made after frame 1A installed shell 15A There are certain height difference Hs between face and tread belt 12A, not only will affect the overall appearance of treadmill, and especially user exists In use, if the speed of service of treadmill and the footfall frequency of user it is inconsistent i.e. treadmill excessive velocities or it is excessively slow when, also Or user is slightly careless in running easily to kick shell 14A, to cause some potential safety problems to using, needs to be changed in fact Into.

In view of this, the designer is not for attaining many missings and not caused by improving in the design of existing running machine structure Just, deeply conceive, and actively research improvement has a fling at and develops and design the utility model.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide that a kind of use is safer, and appearance is more For beautiful treadmill.

In order to achieve the above objectives, the solution of the utility model is:

A kind of treadmill comprising under(-)chassis and the bracket being arranged with under(-)chassis in vertical direction, under(-)chassis Both ends are correspondingly provided with front axle and rear axle, and front roll is installed on front axle, and back roll is installed on rear axle, and tread belt tensioning installs around On front roll and back roll, follower belt is tightly packed on the driving wheel of front roll side, is also set between front roll and back roll There are an intermediate calender rolls, which is arranged close to front roll, and the apical side height of intermediate calender rolls is more than or equal to driving wheel Apical side height, the top surface of the intermediate calender rolls is closely packed together with the tread belt.

Further, the intermediate calender rolls are installed on an axis, and the both ends of axis are fixed on under(-)chassis by mounting post On.

Further, the front end of the under(-)chassis is installed with a front cover, and the rear end of under(-)chassis is installed with rear cover, treadmill Motor, front wheel, front axle and power supply be installed in front cover, rear roller and rear axle are installed in rear cover, the top surface of front cover with The top surface flush of rear cover.

After adopting the above structure, the utility model treadmill is in the structure basis for not changing existing treadmill, in preceding rolling An intermediate calender rolls, the apical side height of intermediate calender rolls and the top of driving wheel are added at the position of front roll between cylinder and back roll The top surface of face height flush or slightly above driving wheel, in this way, when tread belt is stretched on front wheel and rear roller, it is close One end of front wheel can be propped up and consistent with the apical side height of front wheel by intermediate calender rolls so that the tread belt and its before There is no differences in height between the under(-)chassis of side, i.e., smooth accessible in front of tread belt, make treadmill overall appearance more Coordinate, be beautiful, it is often more important that, in user when carrying out road-work in tread belt, due to accessible in front of tread belt, The security risk for kicking baffle during the motion can be eliminated, therefore, the utility model is compared to existing treadmill using more Add safety, appearance is also more aesthetically pleasing.

Specific embodiment

In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into Row elaborates.

As shown in Fig. 5 to Fig. 8, the utility model discloses a kind of treadmill comprising under(-)chassis 1 and and under(-)chassis 1 bracket 2 being arranged in vertical direction, the both ends of under(-)chassis 1 are correspondingly provided with front axle 11 and rear axle 12, before front roll 13 is installed in On axis 11, back roll 14 is installed on rear axle 12, and the tensioning of tread belt 3 is around on front roll 13 and back roll 14, front roll 13 side is installed with driving wheel 4, and follower belt 5 is tightly packed on driving wheel 4, and the key of the utility model is: front roll 13 An intermediate calender rolls 15 are additionally provided between back roll 14, which is arranged close to front roll 13, and intermediate calender rolls 15 Apical side height be slightly larger than or equal to driving wheel 4 apical side height, the top surface of the intermediate calender rolls 15 is abutted against with the tread belt 3 Together.The intermediate calender rolls 15 can be installed on an axis 16, and the both ends of axis 16 are fixed on under(-)chassis 1 by mounting post 17 On.

The front end of the under(-)chassis 1 is installed with a front cover 18, and the rear end of under(-)chassis 1 is installed with rear cover 19, treadmill The structures such as motor, front wheel 13, front axle 11, power supply be installed in front cover 18, rear roller 14 and rear axle 12 are installed in rear cover In 19, the top surface of front cover 18 and the top surface flush of rear cover 19.Since the front end of tread belt 3 is propped up, after under(-)chassis 1 End, which can correspond to, increases, or so that tread belt 3 is kept smooth by the way of padded.Certainly, the rear end of under(-)chassis 1 can also be with Front end forms a gradient, so that tread belt 3 is formed one from rear end toward the inclined gradient in front end, increases exercise intensity.

The utility model treadmill in the structure basis for not changing existing treadmill, in front roll 13 and back roll 14 it Between, at the position of front roll 13 add an intermediate calender rolls 15, the apical side height of intermediate calender rolls 15 slightly above or is equal to transmission The apical side height of wheel 4, in this way, when tread belt 3 is stretched on front wheel 13 and rear roller 14, close to one end of front wheel 13 It can be propped up and consistent with the apical side height of driving wheel 4 by intermediate calender rolls 15, so that the tread belt 3 and the bottom in front of it There is no differences in height between frame 1, i.e. 3 front of tread belt is smooth accessible, coordinate treadmill overall appearance more, beauty It sees, it is often more important that, in user when carrying out road-work in tread belt 3,3 front of tread belt is accessible, so as to disappear Except the security risk for kicking baffle during the motion, therefore, the utility model is used compared to existing treadmill more pacifies Entirely.

The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
