Abstract
The invention discloses a self-weight roller skate; a shaft seat is fixed and arranged below the rear end of a fixed main board; the upper end of the shaft seat is provided with an auxiliary shaft; the auxiliary shaft is provided with a one-way gear and a variable speed gear; the lower end of the shaft seat is provided with a main shaft; the middle of the main shaft is provided with a main shaft gear; both sides of the main shaft are provided with rear wheels; the variable speed gear is engaged with the main shaft; a power rack is arranged between a pedal and the one-way gear; a positioning wheel is fixed and arranged on one side of the shaft seat. The invention has the advantages that each step of the user on the pedal produces pressure which is more than the weight of the body; the power rack drives the one-way gear under the human body weight pressure; the positioning wheel prevents the power rack from sliding externally, so the power rack can be tightly adhered to the gear, and the roller stake can easily move forwards, and does not step back when climbing a slope or running on flat roads.
Description
Technical field
The present invention relates to a kind of roller skate, especially relate to a kind of Deadweight driving dry skate.
Background technology
Existing roller skate has just been installed several runners under sole, pedal ground by the people to oblique rear during motion, utilize reaction force forward to advance, the self gravitation utilization rate of human body is very low, so relatively require great effort, disclosed a kind of Deadweight driving dry skate in the patent that existing China Patent No. is ZL200320111268.X, its structure is the front end that front truckle is fixed on the pedal bottom surface, rear truckle and rear foot wheel shaft are fixed, one end and the rear foot wheel shaft of travel(l)ing rest are hinged, the other end and pedal are hinged, fix with spring between travel(l)ing rest and the pedal, fixing unidirectional drive of rear foot wheel shaft and tooth bar are fixed by bearing and pedal with the tooth bar meshed gears, with the coaxial fixing back of gear large drive wheel, fix by bearing and pedal with the preceding little drive of back large drive wheel engagement, with the coaxial fixing preceding large drive wheel of preceding little drive, preceding large drive wheel and described unidirectional drive engagement, the structure that it is complicated, and be very difficult to realize.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Deadweight driving dry skate simple in structure.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of deadweight roller skate, comprise pedal, fixing mainboard, front-wheel and trailing wheel, described front-wheel is fixed on the front end below of described fixedly mainboard, below, described fixedly mainboard rear end is set with axle bed, described axle bed upper end is provided with countershaft, described countershaft is provided with ratchet, be provided with change-speed gearing on the described countershaft simultaneously, described axle bed lower end is provided with main shaft, the middle part of described main shaft is provided with the main shaft tooth, the both sides of described main shaft are provided with described trailing wheel, described change-speed gearing and the engagement of described main shaft tooth, between described pedal and the described ratchet power tooth bar is set, described axle bed one side is set with locating wheel, described locating wheel is corresponding with described ratchet position, described power tooth bar one end and described pedal flexibly connect, the other end of described power tooth bar is arranged between described ratchet and the locating wheel, the tooth engagement of described power tooth bar and described ratchet, the top of described pedal is hinged on the described fixedly mainboard, and described pedal proximal portion is connected with described fixedly mainboard by spring.
Described ratchet comprises axle sleeve and gear mass, and described axle sleeve is fixed on the described countershaft, is set with at least one spring steel plate on the described axle sleeve, and the inboard of described gear mass is provided with the inclined-plane post that cooperatively interacts with spring steel plate.
Described main floor bottom surface is provided with positive stop strip, and described tooth bar is provided with stopper slot, and described positive stop strip is positioned at described stopper slot.
Compared with prior art, the invention has the advantages that and be set with ratchet on the countershaft, countershaft is set with change-speed gearing, be set with the main shaft tooth on the main shaft, change-speed gearing and main shaft tooth are meshing with each other, be connected by the power tooth bar between pedal and the ratchet, power tooth bar and ratchet cooperatively interact, when pedal is stepped on downwards, the power tooth bar moves downward and drives the ratchet rotation, and with the also and then rotation of change-speed gearing of the coaxial setting of ratchet, the main shaft tooth that meshes with change-speed gearing also rotates, be arranged on main wheel rotation in back on the main shaft thereby drive, bicycle is advanced.When pedal is not stressed, because the reaction force of spring, make pedal be returned to original position, the power tooth bar moves upward, the gear mass backward rotation of ratchet, but because the ratchet structure, gear mass can not drive axle sleeve and rotate, so countershaft is motionless, thereby bicycle is fallen back.
Ratchet comprises axle sleeve and gear mass, and axle sleeve is fixed on the countershaft, is set with at least one spring steel plate on the axle sleeve, and the inboard of gear mass is provided with the inclined-plane post that cooperatively interacts with spring steel plate.When the power tooth bar moved downward, the forward rotation of ratchet middle gear body drove inclined-plane post forward rotation, and when the inclined-plane post cooperated with spring steel plate, spring steel plate impelled axle sleeve to rotate, and rotated thereby drive main shaft, and bicycle is advanced.When the power tooth bar moved upward, the reverse inclined-plane post that initiatively drives of gear mass was done backward rotation, and the inclined-plane post can not drive spring steel plate and rotate, so bicycle can not fall back.
The power tooth bar is between ratchet and the locating wheel, and ratchet can be closely cooperated with the power tooth bar in motion process all the time.
The main floor bottom surface is provided with positive stop strip, and tooth bar is provided with stopper slot, and positive stop strip is positioned at stopper slot.In the power tooth bar was moving up and down process, positive stop strip can move in certain amplitude by the restricted power tooth bar, tooth bar is in ratchet all the time closely cooperates.User's each step on bicycle all can be to the pressure of ground generation greater than body wt, the power tooth bar drives ratchet under people's body weight pressure, locating wheel restricted power tooth bar is not understood outer sliding, is close to gear, roller skate can easily travel forward, and is going up a slope or can not retreat when parallel.
