The utility model has the beneficial effects that：In the utility model, make two pedal assemblies as a result of gear assembly
Linkage, and there are four the above transmission gears sequentially engaged for tool in gear assembly, between ensureing two pedal assemblies between left and right
Away from the case of, the size of single transmission gear can be effectively reduced, structure novel is compact, can effectively reduce this treadmills
Volume, transmission gear are also more easy to be processed and assemble, and facilitate production, transport and use.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the overall structure figure of the utility model；
Fig. 2 is the internal structure chart of the utility model；
Fig. 3 is the exploded view of the utility model；
Fig. 4 is the partial enlarged view of part A in Fig. 3.
Specific implementation mode
Referring to figs. 1 to Fig. 4, a kind of gear set formula treadmills, including main body, main body have step device 10, step device
10 include pedestal 13, gear assembly and two pedal assemblies 12, wherein gear assembly includes the even number sequentially engaged from left to right
The quantity of transmission gear 111, transmission gear 111 is four or more, and each transmission gear 111 is spindle rotationally arranged in pedestal 13
On；Two pedal assemblies 12 are connected to the transmission gear 111 of left end in gear assembly and right end and can be with corresponding transmissions respectively
Gear 111 rotates synchronously.In the utility model, two pedal assemblies 12 are made to link as a result of gear assembly, and gear
Tool is there are four the above transmission gear 111 sequentially engaged in component, between ensureing two pedal assemblies 12 between left and right away from the case where
Under, the size of single transmission gear 111 can be effectively reduced, structure novel is compact, can effectively reduce the volume of this treadmills,
Transmission gear 111 is also more easy to be processed and assemble, and facilitates production, transport and use.Step device 10 is applied in the art
Extensively, remaining suitability structure of step device 10 known to those skilled in the art, not to be described further separately herein.The present embodiment
Middle main body further includes frame body 20, and step device 10 is arranged on frame body 20, and the connecting shaft 121 in the present embodiment is in curved bar shape,
Step device 10 further includes the foot pedal 122 being arranged in connecting shaft 121.
In the utility model, pedal assembly 12 has connecting shaft 121, and connecting shaft 121 is by being keyed structure and driving cog
Wheel 111 is connected and makes pedal assembly 12 that can be rotated synchronously with corresponding transmission gear 111, and structure is more secured, and with stronger
Load-bearing capacity, key connection structure are less prone to fracture and loosen, can effectively avoid accidents, and can effectively extend this reality
With novel service life.In the present embodiment, the middle part of transmission gear 111 is provided with mounting hole 112, and connecting shaft 121 is plugged in
