Description
Technical field
A kind of Tensioning structure of treadmill belongs to a kind of body-building apparatus technical field.Be specifically related to a kind of Tensioning structure of treadmill.
Background technology
Along with improving constantly of people's living standard, indoor body-building is accepted by people gradually at present, and treadmill enters in daily life gradually.Treadmill miscellaneous after using a period of time, the phenomenon of belt slack or even belt creep will occur because of the reasons such as aging and wearing and tearing of belt in the market, may will bring danger to the user.Therefore after treadmill uses a period of time, just need to adjust treadmill belt.So no matter be depot repair or after-sale service personnel on-site maintenance, all can be to the consumer with serving unnecessary trouble.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the problem that prior art exists, treadmill is improved, the belt that makes treadmill is Self-adjustment immediately in use for some time, the Tensioning structure of treadmill of attendant's regular on-site maintenance has been removed in the generation of the phenomenon such as avoided belt slack or skid from.
The technical scheme of the utility model technical solution problem is: the Tensioning structure of this this treadmill comprises the bracing or strutting arrangement that is fixed on fixed head and the adjusting device that is fixed on bracing or strutting arrangement.
described bracing or strutting arrangement comprises stay pipe, connecting plate, U-shaped, expansion tightening wheel and fixed axis, described adjusting device is extension spring, stay pipe is that the column medial surface is provided with a plurality of holes uniformly at intervals, connecting plate one end is fixed on stay pipe the top section by axle, the connecting plate other end is connected with the blind end of U-shaped, axle is fixed in the openend of U-shaped, expansion tightening wheel is arranged on fixed axis, whole jockey is that an arm shape structure is installed on stay pipe, U-shaped lower end is provided with a hole, one end of extension spring is fixed in hole on stay pipe, the other end is fixed in hole on U-shaped, expansion tightening wheel and the stay pipe that will be fixed on U-shaped by extension spring link together, thereby be used for realizing the automatic regulation function of expansion tightening wheel by the pulling force of extension spring.
Described connecting plate is arc.
5 of hole vertical array on described stay pipe.Extension spring is connected in the hole of stay pipe up and down diverse location, can realizes the automatic regulation function of expansion tightening wheel, thereby realize the treadmill belt tightness is regulated.
Compared with prior art, the beneficial effect that the Tensioning structure of treadmill of the present utility model has is: after treadmill increases this swelling device, can the be real-time belt tension degree be regulated, the potential danger such as the belt appearance relaxes or skids have been avoided, consumer oneself just can regulate, removed the periodic maintenance of belt to the worry that the consumer brings, made treadmill be in all the time the state of normal operation, but also service life of the prolongation belt of amplitude peak.
Description of drawings
Fig. 1 is that the Tensioning structure master of treadmill looks schematic diagram.
Fig. 2 is the side-looking structural representation of Fig. 1.
Fig. 3 be treadmill Tensioning structure be arranged on schematic diagram on treadmill.
Wherein: 1, fixed head 2, stay pipe 3, connecting plate 4, U-shaped 5, expansion tightening wheel 6, fixed axis 7, extension spring 8, motor 9, Tensioning structure 10, motor shaft belt pulley 11, belt 12, belt pulley.
The specific embodiment
Fig. 1 ~ 3rd, the most preferred embodiment of the Tensioning structure of the utility model treadmill is described further below in conjunction with the Tensioning structure of 1 ~ 3 pair of treadmill of accompanying drawing.
With reference to accompanying drawing 1-2: the Tensioning structure of treadmill is comprised of fixed head 1, stay pipe 2, connecting plate 3, U-shaped 4, expansion tightening wheel 5, fixed axis 6 and extension spring 7.
wherein: stay pipe 2, connecting plate 3, U-shaped 4, expansion tightening wheel 5 and fixed axis 6 consist of bracing or strutting arrangement, extension spring 7 is adjusting device, stay pipe 2 is flat column, vertically be spaced from the top down a on medial surface, b, c, d, e5 extension spring connecting hole, connecting plate 3 is downward arc, connecting plate 3 one ends are fixedly connected on the top section of stay pipe 2 by axle, connecting plate 3 other ends connect the blind end of U-shaped 4, expansion tightening wheel 5 is fixedly connected in the openend of U-shaped 4 leading sections by fixed axis 6, decurved arm shape structures are installed in stay pipe 2 upper ends of being shaped as of whole bracing or strutting arrangement, the below of U-shaped 4 blind end connecting plate 3 junctions is provided with a hole f, one end of extension spring 7 is fixed in a hole on stay pipe 2, the other end is fixed in the hole f of U-shaped 4, the expansion tightening wheel 5 that will be fixed on U-shaped 4 by extension spring 7 links together with stay pipe 2, thereby be used for realizing the automatic regulation function of expansion tightening wheel 5 by the pulling force of extension spring 7.
On stay pipe 2, vertical spaced hole can also be greater or less than 5 from the top down.
Operation principle and the course of work are as follows: this Tensioning structure 9 is arranged on motor shaft belt pulley 10 1 end rear sides, the bottom of stay pipe 2 is welded on fixed head 1, fixed head 1 is fixed on whole Tensioning structure 9 on the treadmill underframe with bolt by two holes on it, just makes the expansion tightening wheel 5 of Tensioning structure 9 upper ends be pressed on belt 11.Arc connecting plate 3 can not affect its length of appropriate change under the prerequisite that motor 8, belt 11 run well at Tensioning structure 9, to facilitate the installation of Tensioning structure 9 on underframe.Afterwards first with extension spring 7 one end hooks in the lower square hole f of U-shaped 4 blind end connecting plate 3 junctions; Again the other end is hooked on stay pipe 2 in the some holes in a, the b that arrange, c, d, an e5 hole, requires extension spring 7 at this moment must be in the state that is stretched.
When treadmill in use for some time, 11 of belts can slightly be elongated.At this moment, be in the state that is stretched due to extension spring 7, when belt 11 is elongated, due to the effect of himself convergent force of extension spring 7, make the expansion tightening wheel 5 that is pressed on belt 11 be pressed on again on belt 11 and the phenomenon that belt 11 is lax or skid can not occur, thereby having realized the automatic tension regulatory function of belt 11.
When treadmill re-uses a period of time, belt is elongated again, and extension spring 7 returns to nature and when not having convergent force, extension spring 7 need to be hooked in an end on stay pipe 2 hole that moves down this moment, extension spring 7 is stretched again, has the ability of automatic contraction, the same description of operation principle.
The effect of extension spring 7 is: use the effect of extension spring autogenous shrinkage power to drive expansion tightening wheel 5, make expansion tightening wheel 5 be pressed on all the time on belt 11, thereby the phenomenon that belt 11 is lax or skid can not occur, and realize the automatic tension regulatory function of treadmill.
The above, it is only preferred embodiment of the present utility model, be not to be the utility model to be done the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
