Among the figure: 1. 10. brakes of wheel seat 5. rollers 6. rotating shafts 7. braking columns 8. brake teeth 9. teeth groove are gone up the orienting lug 15-1. crotch that heads on 15. to 14. times orienting lug 14-1.V of 11. stage clip 12. elater, 13. crotches type groove 14-2. surface of subsidence 14-3. and are gone into groove and meet block face 15-2. crotch and go out groove spigot surface 16. guide grooves in the outer wheel seats 4. of car body 2. mudwinges 3.
The specific embodiment:
A kind of braking structure of baby cart as shown in Figure 1, comprise car body 1, mudwing 2, outer wheel seat 3, interior wheel seat 4 and roller 5, mudwing 2 is arranged at car body 1 below, outer wheel seat 3, interior wheel seat 4 is captiveed joint with mudwing 2, roller 5 is installed between outer wheel seat 3 and the interior wheel seat 4 by rotating shaft 6, wheel seat 3 is provided with a brake gear outside, described brake gear comprises an elastic telescopic structure, be arranged at the braking column 7 of elastic telescopic structure front end and be arranged at the brake tooth 8 of roller 5 sides, the increment of described brake tooth 8 is the face of cylinder, forms teeth groove 9 between the brake tooth 8.When the elastic telescopic structural elasticity was depressed the un-brake state, as shown in Figure 2, braking column 7 was positioned at outside the teeth groove 9, and during by elasticity jack-up braking state, as shown in Figure 3, braking column 7 is positioned at teeth groove 9 in the elastic telescopic structure.
As shown in Figure 4, described elastic telescopic structure comprise brake 10, stage clip 11 and elater 12, offer on the wheel seat 3 outside and make brake 10 guide grooves that move up and down 16, brake interts 10 in guide groove 13, braking column 7 is fixedly set in the front end that brakes 10, stage clip 11 is arranged in the guide groove 13, the two ends of stage clip 11 offset 10 with outer wheel seat 3 with brake respectively, captive joint with outer wheel seat 3 in the lower end of elater 12, the upper end is provided with crotch 13, in brake 10 sides is provided with the crotch guide frame.As shown in Figure 5, orienting lug 14 and last orienting lug 15 under the described crotch guide frame bag, following orienting lug 14 is by V-slot 14-1, surface of subsidence 14-2, upward head-on 14-3 forms, last orienting lug 15 is for being positioned at the horn structure of the V-slot 14-1 top of orienting lug 14 down, one side is gone into groove for crotch and is met block face 15-1, and one side goes out groove spigot surface 15-2 for crotch.
During brake, brake is applied a downward power to 10 forces brake to move downward 10, the crotch that crotch 13 on the elater 12 is run on the last orienting lug 15 goes out groove spigot surface 15-2, go out to force under the effect of groove spigot surface 15-2 elater 12 distortion to make crotch 13 to left movement at crotch, cancel when acting on brake the power on 10, the brake 10 under stage clip 11 elastic force effects upward movement, crotch 13 on the elater 12 drops on down on the surface of subsidence 14-2 of orienting lug 14, when brake runs to 4 topmost, brake slides into the braking column 7 on 10 in the teeth groove 9 of the tooth 8 that brakes, and braking state is promptly finished.
Separate in a flash, brake is applied a downward power to 10 force brake to move downward 10, make crotch 13 on the elater 12 meet the 14-3 that upward heads on the orienting lug 14 down.Under the effect of last head-on 14-3, force elater 12 distortion that crotch 13 is moved right, when brake runs to 10 bottom, brake has broken away from the braking column 7 on 10 teeth groove 9 of the tooth 8 that brakes, and the crotch on the elater 12 13 has surpassed the head-on most significant end of 14-3 of going up of time orienting lug 14, crotch 13 is to left movement under the effect of elater 12 screen resiliences, go under the stopping that groove meets block face 15-1 at the crotch of last orienting lug 15, when cancelling the power that acts on braking 10, crotch 13 on the elater 12 hooks down the V-slot 14-1 on the orienting lug 14, make brake 4 can not be under the elastic force effect of stage clip 11 upward movement.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
