Embodiment
It is the specific embodiment of the present invention and with reference to accompanying drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
Technical scheme provided by the invention is illustrated in more detail with reference to Fig. 1.
As shown in figure 1, this polywedge bet automatic tension device includes：
Motor 10, there is motor shaft 11；
Roller 20, it is connected by polywedge bet 30 with motor shaft 11, the position of the roller 20 and motor 10 is relatively fixed；On
State motor 10 and roller 20 is preferably installed in treadmill frame structure, and the two is all fixed good position, it is not necessary to adjust
Save the direction such as front and rear；
Automatic tension mechanism, including tensioner element 41 and the reset element 42 that is connected with tensioner element 41, the tensioner
Element 41 contacts with the zone face of polywedge bet 30 and pushes against polywedge bet 30, and the reset element 42 is used for multiple after tensioner element 41 acts
Position, makes tensioner element 41 push against polywedge bet 30 all the time.
The present invention protects a kind of polywedge bet automatic tension device, and by this device, treadmill can be realized for a long time
It is non-maintaining.
This polywedge bet automatic tension device integral structure layout is compact, and motor 10 and roller 20 are all fixed good positions, no
Need to adjust distance, avoid polywedge bet 30 from elongating, skid, subsequently avoid manually adjusting it is cumbersome, the present invention by with polywedge bet
30 close-fitting automatic tension mechanisms realize elastic adjustment, zone face (the i.e. polywedge bet 30 of tensioner element 41 and polywedge bet 30
Wider lateral surface) contact and push against polywedge bet 30 all the time, tensioner element 41 is applied with expanding force (thrust) to polywedge bet 30
But do not interfere the rotation of polywedge bet 30, further avoid the elongation of polywedge bet 30 and skidding produces, even if there is external force interference
Or cause tensioner element 41 to have after the elongation of polywedge bet 30 and depart from the trend of polywedge bet 30, (pulled back in the restoring force of reset element 42
Power) effect under, tensioner element 41 overcome the trend and continue push against polywedge bet 30, pass through this polywedge bet automatic tension device, run
Step machine can be realized prolonged non-maintaining, also overcome existing adjusting elasticity problem.
To be further ensured that tension mechanism and polywedge bet 30, the tight fit of motor 10, roller 20, ensure tensioner effect,
It is preferred that tensioner element 41 is arranged on the periphery of polywedge bet 30 top and is placed between motor 10 and roller 20, the tensioner element 41 to
Lower compression polywedge bet 30 simultaneously makes the epimere of polywedge bet 30 middle part to bottom offset and forms local dent, and the depression at this is polywedge bet
30 can rely on the deformation that itself toughness is replied, and do not destroy the self-strength and toughness of polywedge bet 30, will not more elongate polywedge bet
30。
In the present invention, tensioner element 41 is arranged to tensioner wheel construction, and the tensioner element 41 compresses downwards polywedge bet 30
And can together be rotated with polywedge bet 30, i.e., drive expansion tightening wheel to rotate when polywedge bet 30 is driven, such structure cloth of tensioner element 41
Office can not only coordinate with the flat belt-like close structure of polywedge bet 30, and the lower distribution of the compressive stress in expansion tightening wheel periphery is uniform, it is thus also avoided that rises
Bearing up pulley stress concentration occurs so as to the situation of lower compressive strain polywedge bet 30, avoids tensioner element 41 from interfering the normal of polywedge bet 30 to turn
It is dynamic.
Further, automatic tension mechanism also include connector 43 and with the relatively-stationary fixed seat 44 in the position of motor 10,
The 43 V-shaped structure setting of connector and its middle part by rotary shaft 45 is articulated with the front end of fixed seat 44, the tensioner element
41 are articulated with the forward end of connector 43, and the reset element 42 is connected with the rear end of connector 43 and provided backward for connector 43
Pulling force, make tensioner element 41 continue to compress polywedge bet 30 downwards.
Fixed seat 44 is used to fixing and supporting overall automatic tension mechanism, and fixed seat 44 is relative with motor 10, roller 20
Transfixion, reset element 42 are continuously applied to the pulling force away from the direction of tensioner element 41, pull connector 43 and make rising for front end
Tight element 41 persistently compresses polywedge bet 30, ensures functional reliability.
For the compactedness of further lifting layout, ensure fixed seat 44 and the compactness that connector 43 connects, reduce part
Interference, it is preferable that the front end of fixed seat 44 has dug the first open slot, the middle part of connector 43 submerge in the first open slot and with
The front end of fixed seat 44 is hinged, and the rotary shaft 45 extends through the front end of fixed seat 44 and the middle part of connector 43.
For the compactedness of further lifting layout, ensure the compactness that connector 43 and tensioner element 41 connect, preferably connect
The forward end of fitting 43 has dug the second open slot, and the tensioner element 41 is placed in the second open slot and is hinged with connector 43
Connection, the motor shaft 11 is placed in the ring of encirclement of V-arrangement connector 43, i.e., motor shaft 11 be located at the front-end and back-end of connector 43 it
Between.
Further, to ensure the stability of the reliability of the support of fixed seat 44 and the work of overall automatic tension mechanism,
The polywedge bet automatic tension device of the present invention also includes and the relatively-stationary fixed support 50 in the position of motor 10, the fixed seat 44
Rear end is provided with the breach agreed with fixed support 50, and the rear end of fixed seat 44 is resisted against on fixed support 50, now fixed branch
The counter structure of frame 50 is located in the breach.
Preferably, the reset element 42 in this case is arranged to continue to after pulling connector 43 away from the direction of tensioner element 41
The spring structure at end, the reset element 42 are connected with the rear end end of connector 43.
In the present invention, connector 43 is first fixed on fixed seat 44, spring constantly applies pulling force and passes through rotary shaft 45
Conduction is on expansion tightening wheel, and expansion tightening wheel continues to compress polywedge bet 30 downwards and rotated with it, and by this device, treadmill can
It is prolonged non-maintaining to realize.
In addition, the present invention also protects a kind of treadmill using above-mentioned polywedge bet automatic tension device, it is possible to achieve when long
Between it is non-maintaining, solve the elastic regulation problem of common polywedge bet.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
