Description
Technical field
The utility model relates to the technical field of body-building apparatus, refers in particular to a kind of machine of kicking one's legs.
Background technology
In the modern life, along with the gradually raising of people's living standard, people also pay close attention to more to the health status of self.Very popular a kind of exercising way is body-building in the gymnasium at present, moulds perfect stature, improves fitness.Body-building apparatus is varied, and still, each gymnasium can have one or several the machine of kicking one's legs, because the frequent sitting posture office of people, fat is easy to pile up at thigh, produces the problems such as lower limb vascular is aging.The maximum characteristics of machine of kicking one's legs can be tempered thigh and buttocks muscles exactly very targetedly, and its security is the highest in all shank composite moves.The machine of kicking one's legs can conduct special training for shank and buttocks, reaches the increase lower limbs strength, carries stern, strengthens blood circulation, and the effect of losing weight and improving the health is very popular.
But the existing machine of kicking one's legs generally has the parts such as frame 1, pedal 2, seat cushion group 3, guide rod 4, gear adjusting mechanism 5 and controlling organization 6.Controlling organization 6 comprises handle and transmission mechanism, by gear adjusting mechanism 5 and controlling organization 6 mating reactions, restrict foot pedal travel.In use, people's both legs are pedaled pedal 2, and seat cushion group 3 is slided up and down along guide rod 4, come leg exercising muscle, require in use, and seat cushion group 3 is slided smooth and easy steady at guide rod 4.
The tradition mode that the seat cushion group 3 of machine slides up and down of kicking one's legs is to adopt linear bearing, and linear bearing drives seat cushion group 3 along sliding on the guide rod 4, and this kind mode has following shortcoming:
One, the requirement of strength to linear bearing is very high, and manufacturing cost is high;
Two, kick one's legs machine people's body weight of use there is certain limitation, can't satisfies various crowds' demand.
In the present machine of kicking one's legs, the mode that seat cushion group 3 slides up and down also has the employing roller, roller 7 drives seat cushion group 3 along sliding on the guide rod 4, roller 7 adopts the layout type of every side " upper two next ", as shown in Figure 1, in the both sides of the machine of kicking one's legs, two rollers 7 are on guide rod, and namely two rollers are respectively a front upper roller 701 and rear upper roller 702; The structure of a roller below guide rod, namely bottom roller 703.As shown in Figure 2, roller 7 is comprised of roller body 71, axle sleeve 72, roller edge cover 73 and deep groove ball bearing 74.The outer nock 711 of roller body 71 is close to guide rod, and outer nock 711 degree of depth of roller body 71 are d1.The axial dimension of roller 7 is L1.Distance is consistent between distance between two side wheels 7 and two guide rods 4, and two guide rods 4 are parallel, and roller 7 is clamped guide rod 4, and tightness is moderate, and the material of roller adopts TPU, to guarantee hardness and security.This kind mode has following shortcoming:
One, install roller after, the roller above-below direction can not agree with fully with guide rod, after especially the people took seat cushion, " Jack of all trades " phenomenon was more serious;
Two, between two side wheels between distance and two guide rods distance can not guarantee unanimously, be in particular in that indivedual roller external arc can't agree with guide rod, block easily in the seat cushion group sliding process, jolt when the slip of seat cushion group occurring, not steady situation smoothly;
Three, roller is in use fragile, trailing wheel especially, because trailing wheel bears more human body weight, and the crushed phenomenon of easier generation roller.
Therefore, the inventor makes further research this, develops a kind of machine of kicking one's legs, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of machine of kicking one's legs, and overcomes the problem that causes the frangible and slip stationarity of trailing wheel because of human body weight, and the cushion group is slided steadily, and pulley is durable through using.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of machine of kicking one's legs, gear adjusting mechanism and controlling organization with frame, pedal, seat cushion group, guide rod, restrict foot pedal travel, has a bottom roller below the guide rod, have three rollers above the guide rod, be respectively upper roller and front upper roller after two, upper roller is fixed together by connector after two.
Preferably, connector is fixed head, have two through holes on the fixed head, lay respectively at the two ends, the left and right sides of fixed head, the both sides of rear upper roller rotating shaft respectively have a fixing hole, on the upper roller, two fixed heads laid respectively at the both sides of rear upper roller after fixed head passed by screw and is fixed on two behind the fixing hole of through hole on the fixed head and rear upper roller.
Preferably, the stage casing of fixed head also has locating hole, and locating shaft is plugged in two locating holes.
Preferably, the roller body of roller is made by the acetal resin material.
Preferably, the outer nock depth as shallow of the outer nock depth ratio prior art of the roller body of roller.
Preferably, the outer nock degree of depth of the roller body of roller is 4 ± 0.1 millimeters.
Preferably, the axial dimension of roller has shortened than the axial dimension of prior art.
Preferably, the axial dimension of roller is 59.4 millimeters.
After adopting such scheme, the utility model compared with prior art has the following advantages:
One, install roller after, the roller above-below direction can both agree with fully with guide rod, the people can not produce Jack of all trades's phenomenon after taking seat cushion;
Two, because the roller above-below direction can agree with fully with guide rod, in seat cushion group sliding process, improved the slip stationarity;
Three, roller adopts the layout type of every side " upper three next ", has solved because trailing wheel bears more human body weight and has held squashy problem.
