Abstract
The utility model discloses a belt synchronizing device of an exercise bicycle. The belt synchronizing device comprises two pulleys and an elastic body, wherein the two pulleys are arranged on the two sides of a belt respectively; the elastic body is connected between the two pulleys. The belt synchronizing device is arranged on a belt transmission mechanism; by means of the elastic action of the elastic body, the belt can be kept in a tensioned state all the time when two wheels (driving wheels or driven wheels) rotate forwardly or reversely, so that a step of subsequently and manually adjusting the belt tensioning degree is avoided; a belt skid phenomenon is effectively improved.
Description
Technical field
The utility model relates to a kind of technical field of exercycle, and is special relevant with the belt synchronizer of exercycle.
Background technique
In the prior art, exercycle adopts the ordinary straps driving mechanism, as shown in Figure 1, by two wheels 10 and 20 and belt 30 forms, when wheel 10 during for driving wheel wheel 20 be driven wheel, wheel 10 is driven wheel when wheel 20 is driving wheel.Before the use, by adjusting the wheelbase D between two wheels 10 and 20, the belt on wheel 10 and 20 30 is tightened.But after use a period of time, as shown in Figures 2 and 3, belt 30 can be aging, makes belt 30 fluff, thereby cause the wheel 10 or 20 as driven wheel skidding to occur, influences the transmission effect.
The model utility content
The purpose of this utility model is to provide a kind of exercycle belt synchronizer, to increase elasticity interlock tension force, improves the belt slippage phenomenon.
In order to reach above-mentioned purpose, solution of the present utility model is:
Exercycle belt synchronizer comprises two pulleys and elastomer, and two pulleys are separately positioned on the both sides of belt, and elastomer is connected between two pulleys.
Described elastomer is spring.
Described elastomer is elastic rope.
After adopting such scheme, the utility model is installed on the belt gear, by elastomeric elastic reaction, make belt when two wheels (driving wheel or driven wheel) forward or reverse, all can keep tensioning state, remove from and use follow-up artificial adjustment belt tension degree, and improved the belt slippage phenomenon effectively.
Below in conjunction with drawings and the specific embodiments the utility model is done detailed explanation.
Description of drawings
Fig. 1 is the structural representation of ordinary straps driving mechanism;
Fig. 2 is the use phase diagram one of ordinary straps driving mechanism;
Fig. 3 is the use phase diagram two of ordinary straps driving mechanism;
Fig. 4 is structural representation of the present utility model.
Label declaration
Embodiment
Consult shown in Figure 1ly, the exercycle belt synchronizer that the utility model discloses comprises that 2, two pulleys 1 of two pulleys 1 and elastomer are separately positioned on the both sides of belt 30, and elastomer 2 is connected between two pulleys 1.Wherein, elastomer 2 can have the member of elasticity interlock tension for spring, elastic rope or other.
The utility model provides elasticity interlock tension by elastomer 1 in use, makes belt 30 all can keep tensioning state when two wheels 10 and 20 forward or reverse, has improved the belt slippage phenomenon effectively.
Being specific embodiment of the utility model only below, is not the restriction to protection domain of the present utility model.All equivalent variations of doing according to the mentality of designing of this case all fall into the protection domain of this case.
