Abstract

The utility model provides a torsion slide bicycle, which mainly comprises a head rod, a front wheel frame, a bundling sleeve component, two body rods, a pedal plate, a rear wheel and a brake. A joint between two body rods and two side plates of the bundling sleeve component is inserted and assembled mainly by a concave convex structure arranged on the joint, thus a positioning block is firmly connected and the rotational loosening is prevented. The utility model achieves the purpose of adjusting an axle distance between the front and back wheels so as to change the effect of torsion of the body by a pivoting hole structure provided with a plurality of positioning rims of the front wheel frame and a length adjusting part arranged on the body rod. The locking of the brake is prevented by the braking mode formed by a single rotating supporting rod adopted by the brake used as the unilateral pressing of the wheel plane.

Description

The torsion scooter

Technical field

The utility model relates to the torsion scooter, is meant firm, the adjustable car load body twisting effect of a kind of winding especially and prevents the torsion scooter that brakes locked.

Background technology

The torsion scooter is that a kind of utilization both feet are stepped on wheels pedal thereafter, and the state that crawls that makes front-wheel be twisting by the twisting handle is made the outdoor activity equipment of advancing; Referring to Fig. 1,2, practise formula torsion scooter after generally using practice, find that its shortcoming is as follows:

1, is an outer rake angle towards the rear because of two vehicle body bars 10, so have a tortuous winding position 13 with the connecting rod 12 at headstock bar 11 positions, strength when the car body twisting can't be born as if employing solid welding mode in this position, so adopt the screw-in version winding generally speaking, yet this kind mode will produce the phenomenon that day by day unscrews because of the car body twisting, still is not very firm therefore.

2, pattern is connected because of the axle center 15 of its front-wheel 14 all is fixedly with vehicle body bar 10, so the wheelbase of 14,16 of front and back wheels obviously can't be adjusted, effect is single and lack variability when causing it to rock, and can't satisfy customer's multiple demands.

3, referring to Fig. 3, the brake gear 17 that general this kind commonly used the torsion car is directly applied mechanically the employed bilateral of the bicycle urgent formula brake of folder synchronously mechanism, the deadlock phenomenon of this kind brake mechanism takes place often for the bicycle of wheel body greater than torsion car several times, well imagine, this kind folder is compeled the easier small and exquisite torsion back wheels of vehicle 16 that allows of formula brake mechanism deadlock phenomenon, the safety that causes car body to skid and topple over and jeopardize the user of service is taken place.

Summary of the invention

The purpose of this utility model provides a kind of torsion scooter, and its two vehicle bodies bar and connecting piece interlocking are firm; It can adjust the front and back wheel wheelbase to adjust car body twisting effect; And it is locked to prevent to brake.

For achieving the above object, technical solution adopted in the utility model is as follows:

A kind of torsion scooter mainly comprises:

One headstock bar, by horizontal handle bar and upright to the end pipe constituted;

One front wheel carrier, the pivot group is pivoted for front-wheel in headstock bar bottom;

Two vehicle body bars, front end are connected to the headstock bar by beam combination cover member jointly; Two vehicle body bar tail ends are then organized respectively and are provided with pedal and trailing wheel;

One brake gear is arranged at the trailing wheel place; It is characterized in that: described collar member is made up of a branch of block set, two side plates and a pipe link; Two vehicle body bar front end transmitted beams cover cover for seat is fixed in the headstock bar, and two vehicle body bars and collar member are by winding position Joint; Two vehicle body bar stage casings are provided with length adjustment portion; Described front wheel carrier is worn the Kong Chengyi strip shape hole that is pivoted of group for the front wheel spindle bolt, and is formed with several location edges in the hole; Described brake gear is the one-sided formula of compeling of supporting.Wherein:

Two side plate front ends of described collar member utilize key to be articulated in collar seat front end, and two side plate rear ends then utilize pipe link to cooperate key lock group to connect; The position is provided with the protuberance and the recess of tabling but two side plate rear ends and two vehicle body bars are connected with group, and protuberance and recess are offered involutory group and established the hole, two side plates utilize key to pass group to establish the hole solid with two vehicle body bar groups respectively.It is by the set jog in two side plate connecting parts in this two vehicle bodies bar and the collar member, make this position wear group locking and reach and fixedly positioning, prevent that rotation from getting loose, avoided commonly using the torsion scooter and screwed togather the phenomenon that the winding mode day by day unscrews with the period of service lengthening by bolt.

The length adjustment portion of described vehicle body bar is made up of inner and outer pipes phase pivot cover, the end that described outer tube inserts for interior pipe is provided with and makes the elastomeric profile groove of this end tool, and this end ring is provided with outside thread, the lock ring screw lock of one tool negative thread is flexible adjustment or stationary state by uncaging of this lock ring to control this inner and outer pipes in this end outside thread periphery.Described length adjustment portion can adjust in than the length scope, adds the hole that is pivoted of set several location edges of tool of front wheel carrier simultaneously, and the wheelbase that can adjust front and back wheel is to change car body twisting effect.

Described brake gear is established a circumflex branch bar by rear wheel frame and the at interval suitable distance group of trailing wheel, circumflex branch bar pivot group one brake lever, the line winding is controlled in brake lever one end and brake, and in addition end then is provided with and controls line in brake and draw and support under the pressure of the trailing wheel wheel face to reach the portion of compeling that supports of brake deceleration effect when pulling the brake lever rotation; Described brake lever and circumflex branch bar pivot group position more combo have revolving of the brake lever of making to move the torque spring that work has restoring force.It has reduced deadlock phenomenon.

According to above-mentioned structure, the utlity model has following advantage:

1, winding is firm: the utility model is by the set jog in two side plate connecting parts in this two vehicle bodies bar and the collar member, makes this position wear the group locking by bolt and reaches and fixedly positioning, prevent to rotate the purpose that gets loose.

2, adjustable car load body twisting effect: the utility model nationality has the flexible structure of adjusting by be pivoted hole and the vehicle body bar of set several location edges of tool of front wheel carrier and is length adjustment portion, and the wheelbase that can adjust front and back wheel is to change car body twisting effect.

3, prevent to brake locked: the utility model nationality is made one-sided wheel face by the single circumflex branch bar that is adopted in its brake gear and is supported the brake mode of compeling, and it is locked to prevent to brake.
