Background technology

Kickboard Scooter is owing to integrate amusement, body-building and lie fallow and more and more be subjected to liking of consumers in general, and this industry has obtained tremendous development in recent years.In order to reduce Kickboard Scooter transport package volume and collection space, between car body and front-wheel steering pipe, generally all folding device to be set, for this reason, applicant had also once successfully been developed a kind of Kickboard Scooter folding device, and applied for Chinese patent on May 22nd, 2004, on May 18th, 2005 Granted publication, the patent No. is 200420023042.9; This structure comprises folding square tube, left and right sides hinge seat and the car body that is fixed on the front-wheel steering pipe, left and right sides hinge seat is fixed on the car body, folding square tube is arranged between the hinge seat of the left and right sides and is hinged by hinge and left and right sides hinge seat, be provided with support hook by turning cylinder between the hinge seat of the described left and right sides, support hook is fixed on the turning cylinder and with folding square tube mates, and an end of turning cylinder stretches out left and right sides hinge seat and is fixed with the dropout spanner; Be provided with locking piece between the protrusion position of described left and right sides hinge seat, locking piece is provided with the locking spanner; Described hinge is provided with spring leaf, and spring leaf one end is against on the preceding tube wall of folding square tube, and the other end is against on the support hook.But still there is weak point in this structure: the one, and processing and assembly technology complexity, required part is many, and efficiency of assembling is low, cost is high; The 2nd, the connection structure mechanical strength is low, and folding device weares and teares easily, deformed damaged, and product design is difficult to ensure.

Summary of the invention

For overcoming the disadvantage that above-mentioned Kickboard Scooter folding device exists, problem to be solved in the utility model provide a kind of simple and reasonable, use is easy to process, cost is low, reliable quality Kickboard Scooter folding device.

The technical scheme that its technical matters that solves the utility model adopts, it comprises that the folding square tube, the symmetry that are fixed on the front-wheel steering pipe are fixed on front and back hinged seat and the car body on the car body, before and after folding square tube is arranged between the hinged seat and hinged by hinge and front and back hinged seat, described front and back hinged seat is provided with symmetrical arc chute, and the two ends, the left and right sides of arc chute are connected with locking slot; Be hinged with rocking arm by hinge in the described folding square tube, hinge is provided with torsion spring; an end of rocking arm spanner part stretches out folding square tube; the other end is provided with guide hole; the both sides of folding square tube are provided with symmetrical guide groove and corresponding with guide hole, and the screw rod of the button that is locked passes the guide groove of folding square tube and the guide hole of operation rocking arm is arranged on the arc chute of front and back hinged seat.

Described arc chute is the center of circle with the hinge; Described locking slot is the center of circle with the hinge.

After adopting said structure, during normal the use, folding square tube leans forward; rocking arm drives the button that is locked under the spring force effect of torsion spring screw rod enters in the locking slot of arc chute right-hand member and plays positioning action; folding square tube can not freely be rotated; the button that is locked again, rocking arm can not be rotated around hinge, can guarantee that folding device fixes reliably all around; When folding; rocking arm drives the button that is locked under the spring force effect of torsion spring screw rod enters in the locking slot of arc chute left end and plays positioning action; folding square tube can not freely be rotated; button again is locked; rocking arm can not be rotated around hinge, can guarantee the reliability that folding device folds.

The specific embodiment

Illustrated in figures 1 and 2, specific embodiments for a kind of Kickboard Scooter folding device of the utility model, it comprises that the folding square tube 2, the symmetry that are fixed on the front-wheel steering pipe 1 are fixed on front and back hinged seat 4,41 and the car body 8 on the car body 8, it is also hinged between the hinged seat 4,41 before and after folding square tube 2 is arranged on by hinge 9 and front and back hinged seat 4,41, described front and back hinged seat 4,41 is provided with symmetrical arc chute 5, and the two ends, the left and right sides of arc chute 5 are connected with locking slot 6; Be hinged with rocking arm 3 by hinge 11 in the described folding square tube 2, hinge 11 is provided with torsion spring 10, torsion spring 10 1 ends lean against the inwall of folding square tube 2, the other end be located at rocking arm 3 above, make rocking arm 3 that one clws spring pressure be arranged all the time; an end of rocking arm 3 spanners part stretches out folding square tube 2; other end is provided with the guide hole that screw rod 13 is installed; the both sides of folding square tube 2 are provided with symmetrical guide groove 12 and corresponding with guide hole, the screw rod 13 of the button 7 that is locked passes the guide groove 12 of folding square tube 2 and the guide hole of operation rocking arm 3 is arranged on the arc chute 5 of front and back hinged seat 4,41.Described arc chute 5 is the center of circle with hinge 9 preferably, and described locking slot 6 is the center of circle with hinge 11 preferably, can make screw rod 13 smooth transition in arc chute 5 and locking slot 6 when folding like this.

When the utility model normally uses, before and after folding square tube 2 is hinged on the hinged seat 4,41 and lean forward; rocking arm 3 drives the button 7 that is locked under the spring force effect of torsion spring 10 screw rod 13 enters in the locking slot 6 of arc chute 5 right-hand members and plays positioning action; folding square tube 2 can not freely be rotated; before and after the button 7 that will be locked again is locked on the hinged seat 4,41; end of rocking arm 3 promptly is fixed, rocking arm 3 can not be around hinge 11 rotations, can guarantee that folding device fixes reliably.

When needs are folding, at first unclamping the button 7 that is locked, pull rocking arm 3 spanners downwards, rocking arm 3 overcomes and drives the locking slot 6 that be locked button 7 and screw rod 13 thereof break away from left ends behind the spring force of torsion spring 10 and enter in the arc chute 5; Rotate the spanner that folds square tube 2 and unclamp rocking arm 3 then, screw rod 13 slides in arc chute 5; When screw rod 13 slides into the locking slot 6 of arc chute 5 right-hand members; rocking arm 3 drives be locked button 7 and screw rod 13 thereof and enters automatically in the locking slot 6 of arc chute 5 right-hand members and play positioning action under the spring force effect of torsion spring 10, folding square tube 2 can not freely be rotated; Be locked again and detain 7, rocking arm 3 can not be rotated around hinge 11, can guarantee the reliability that the utility model is folding, thereby finish folding.
