Abstract

The utility model relates to an automatic roller-skating shoe which comprises a footplate, a shoe body, wheels, a reset spring, gear quadrants, a gear transmission mechanism and a ratchet over-running clutch; wheels are mounted on the shoe body through axles; gears are respectively mounted on the middle parts of the front axle and the back axle; gear quadrants which are meshed with gears are mounted on the shoe body through pin shafts; the upper parts of gear quadrants are connected with a fork type upright column fixed on the footplate; the reset spring is arranged between the footplate and the bottom plate of the shoe body. The automatic roller-skating shoe has the beneficial effects of adopting human gravity as power to drive the roller-skating shoes to slide forwards, having smooth sliding movements, saving energy, simple and compact structure, lightness and easy carrying.

Description

Automatic roller skate

Technical field

The utility model relates to a kind of automatic roller skate.

Background technology

At present, roller skate commonly used (or claiming roller skate) has two kinds of forms: a kind of is the four-wheel footwear, and two-wheel front and back arrangement form and line arrangement form of four-wheel are arranged; Another kind is two-wheeled footwear (two-wheel is arranged in arch of the foot portion).The common feature of these two kinds of roller skate is: when sliding by two legs successively to proceeds posterolateral to the masterpiece of pedaling advance in a zigzag, just as the skating, so be known as roller skate; Owing to can not move ahead by straight line, pace has been subjected to influence; Because the zigzag track, everyone required ground fabric width is bigger, and many people move together and are restricted; Because some component is wasted the human body fatiguability.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of simple in structure, can autoamtic boosting, the automatic roller skate that easily slides.

The technical scheme that its technical problem that solves the utility model adopts:

The utility model includes pedal, fuselage, wheel, back-moving spring, fan tooth, gear drive, ratchet freewheel clutch; Wheel is installed on the fuselage by axletree, middle part at forward and backward axletree is separately installed with gear, the fan tooth that is meshed with each gear is installed on the fuselage by bearing pin, the top of described fan tooth is connected with forked stanchion on being fixed on the pedal bottom surface by bearing pin, be provided with back-moving spring between the base plate of pedal and fuselage, the number of back-moving spring is 2-3.

The ratchet of described ratchet freewheel clutch is the clutch inner ring, is provided with the roller slot of a pair of symmetry on the cylindrical of described ratchet, is provided with the semicircle cambered surface in the notch force part of roller slot; Wheel hub is the outer ring of clutch, is evenly equipped with 10 semicircular arc grooves on the interior circle of wheel hub; Two rollers lay respectively in the corresponding roller slot.

The utility model also includes the bandage of the fastening shoes that are positioned at the pedal both sides, the S shape bandage locking of being made by roll of steel plate blocks; Be provided with saw-tooth thread in the upper slot of S shape bandage locking card, the saw-tooth thread on the bandage of this saw-tooth thread and corresponding section matches.

The utility model also includes two brake block, and two brake block are installed in the below of fuselage front and back ends.

The beneficial effects of the utility model are that it utilizes the body weight for humans masterpiece to advance and slide for power drives roller skate, and gliding motility is brisk, laborsaving; Simple in structure, compact, lightly portable.

The specific embodiment

By the embodiment shown in Fig. 1-9 as can be known, it includes pedal 4, fuselage 7, wheel 10, back-moving spring 6, fan tooth, gear drive, ratchet freewheel clutch; Wheel 10 is installed on the fuselage 7 by axletree 13, be separately installed with gear 9 at the middle part of forward and backward axletree, the fan tooth 5 that is meshed with each gear 9 is installed on the fuselage 7 by bearing pin, the top of described fan tooth 5 is connected with forked stanchion 3 on being fixed on pedal 4 bottom surfaces by bearing pin, is provided with two back-moving springs 6 between the base plate of pedal 4 and fuselage 7.

The ratchet 14 of described ratchet freewheel clutch is the clutch inner ring, is provided with the roller slot 15 of a pair of symmetry on the cylindrical of described ratchet 14, is provided with semicircle cambered surface 16 in the notch force part of roller slot 15; Wheel hub 17 is the outer ring of clutch, is evenly equipped with 10 semicircular arc grooves 18 on the interior circle of wheel hub 17; Two rollers 19 lay respectively in the corresponding roller slot 15.

Present embodiment also includes the bandage 1 of the fastening shoes that are positioned at pedal 4 both sides, the S shape bandage locking of being made by roll of steel plate blocks 2; Be provided with saw-tooth thread 20 in the upper slot of S shape bandage locking card 2, the saw-tooth thread 21 on the bandage of this saw-tooth thread 20 and corresponding section matches.The effect of S shape bandage locking card is to lock bandage fast, reliably, again can be easy and convenient untie bandage.

Present embodiment also includes the below that 8, two brake block 8 of two brake block are installed in fuselage 7 front and back ends.

In Fig. 2,11,12 is bearing.

The course of work of present embodiment is as follows:

When pin pushes down on the pedal, human body gravity is by being positioned at the fan tooth of fuselage, gear drive is rotated axletree, axletree drives wheel by ratchet freewheel clutch bonding state again and rotates, like this, automatic roller skate just carries human body and advances, when pin unclamps, when pedal lifts, axletree then stops operating, at this moment the ratchet freewheel clutch on the axletree is then in released state, and wheel continues roll-sliding by inertia force, when both feet are stepped on successively and lifted, automatic roller skate then carries human body and slides fast, during with a roller skate perk forward or backward, brake block contacts to earth when artificial, and roller skate is just being slowed down or braking is stopped.

The course of work of ratchet freewheel clutch is as follows:

When axletree was active rotation, the roller in the roller slot on the ratchet was thrown away by centrifugal force, compressed mutually with semicircle cambered surface on the circle in the hub for vehicle wheel, and at this moment the inside and outside circle of clutch is locked, and clutch is in bonding state, and the axletree band wheel and rotated; And when axletree did not change, the inclined-plane on the semicircular arc groove in the hub for vehicle wheel on the circle back into roller in the roller slot on the ratchet, and at this moment the inside and outside circle of clutch is in released state, and wheel is coast performance on axletree then.

The function of sliding after the ratchet freewheel clutch prevents to go up a slope in addition (anti-back skating) makes and can take a step when going up a slope to go up a slope.
