Abstract
The utility model discloses a deadweight skeeler. An axle bed is fixedly positioned below the rear end of a fixed mainboard; a countershaft is positioned at the upper end of the axle bed; a unidirectional gear and a transmission gear are positioned on the countershaft simultaneously; a mainshaft is positioned at the lower end of the axle bed; a mainshaft gear is positioned at the central part of the mainshaft; rear wheels are positioned at both sides of the mainshaft; the transmission gear is meshed with the mainshaft gear; a power rack is positioned between the pedal and the unidirectional gear; a positioning wheel is fixedly positioned at one side of the axle bed. The deadweight skeeler has the advantages that each step of the user on the bicycle puts pressure larger than the body weight of the user on the ground; under the pressure of the weight of the user, the power rack drives the unidirectional gear; the positioning wheel prevents the power rack from sliding outside and ensures the power rack to cling to the gear tightly; the skeeler can move forward easily, without falling back when the skeeler is used to climb up a slope or put in parallel.
Description
Technical field
The utility model relates to a kind of roller skate, especially relates 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.
The utility model content
Technical problem to be solved in the utility model provides a kind of Deadweight driving dry skate simple in structure.
The utility model 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, advantage of the present utility model is to be set with on the countershaft ratchet, 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.
