Summary of the invention
The utility model provides a kind of braking mechanism of perambulator, has solved the inconvenient problem of pedal control of using.
A kind of braking mechanism of perambulator; Comprise wheel shaft, wheel and be located at the wheel inboard and be fixed on the brake mount on the wheel shaft; The vehicle wheel hub face is provided with the spoke hole of uniform ring around wheel shaft, and brake mount is provided with the through hole of parallel axletree, is provided with the brake pin of overcoat retracing spring in the through hole; Brake mount away from wheel one end be provided with through hole vertically cross in establish the slide opening of slide block; Slide block over against through hole one side be provided with the bottom surface from the top to the bottom to through hole direction bevelled chute; Brake pin passes away from wheel one end that through hole stretches in the chute and against the bottom surface of chute, a brake cable is drawn on the slide block top; This braking mechanism also comprises the steering unit of being made up of spanner that is hinged and base, and the manipulatable end of said brake cable connects spanner.
Described brake pin is made up of leading portion, back segment and recoil spring between the two, and said leading portion stretches into chute away from recoil spring one end, avoids the brake pin to insert spoke hole suddenly.
Said brake pin stretches into chute and is hemisphere face against an end end face of chute bottom surface, reduces friction, promotes and handles comfort.
Said base is provided with the groove that cooperates with spanner, is provided with the rotating shaft of passing spanner in the groove.
The utility model braking mechanism is controlled the brake pin through spanner and brake cable, has improved the manoevreability of operation, has effectively avoided maloperation.
Description of drawings
Fig. 1 is the perambulator of band the utility model braking mechanism;
Fig. 2 is the exploded view of the utility model braking mechanism;
Fig. 3 is the preceding section-drawing of the utility model braking mechanism brake;
Section-drawing when Fig. 4 brakes for the utility model braking mechanism.
The specific embodiment
Perambulator as shown in Figure 1 comprises the wheel 2 of vehicle frame 3, bottom of frame and the wheel shaft 1 that connects two wheels, and the vehicle frame top is provided with steering unit 4.
Like the described braking mechanism of Fig. 2; Comprise wheel shaft 1, be fixed on the wheel 2 at wheel shaft 1 two ends and be located at the brake mount 5 on the inboard fixedly wheel shaft of wheel; 2 wheel hub surfaces of wheel are provided with some spoke holes 201 around axletree 1; Brake mount 5 is provided with the through hole 502 of parallel axletree, is provided with the brake pin 7 of overcoat retracing spring 8 in the through hole 502, and brake pin 7 is made up of leading portion 701, back segment 702 and recoil spring between the two 703.
Brake mount 5 is provided with the slide opening 501 that vertically crosses with through hole 502 away from wheel 2 one ends; Be provided with a slide block 6 in the slide opening; Slide block 6 is provided with chute 601 over against through hole 502 1 sides; The bottom surface of chute 601 tilts to the through hole direction from the top to the bottom, and the leading portion 701 of brake pin 7 passes through hole 502, stretches into chute 601 and against the bottom surface of chute.
Steering unit 4 is made up of spanner 401 and base 403, and base 403 is provided with the groove 404 that cooperates with spanner 401, is provided with the rotating shaft 402 of passing spanner 401 in the groove 404.Brake cable 9 is drawn on slide block 6 tops, and brake cable 9 one ends stretch into slide opening 501 and are connected with slide block 6, and the other end connects spanner 401.
The principle of work of above-mentioned brake is following:
As shown in Figure 3, before the brake, because the tension force of retracing spring 8, whole of brake pin is positioned at through hole 502, and leading portion stretches in the chute 601 away from wheel 2 one ends, and in order to reduce friction, this end end face is arranged to hemisphere face.As shown in Figure 4, during brake, pull spanner 401; Braking rope 9 traction slide blocks 6 move straight up, and chute 601 bottom surfaces push brake pin 7 to the motion of wheel 2 directions, compress recoil spring 702 and retracing spring 8 simultaneously; Insert in the spoke hole 201 until brake pin 7, realize brake.Decontrol spanner, retracing spring and 702 elongations of buffering spring make brake pin 7 withdraw from spoke hole 201, and leading portion stretches into chute 601 again simultaneously, abuts ramp surface and stop motion.
