Children use the beach buggy post brake device
Technical field
The utility model relates to the brake equipment of self-propelled vehicle, and especially children use the beach buggy post brake device.
Background technology
Existing children generally are to continue to use the structure of adult with the beach buggy brake equipment with the brake equipment of beach buggy, mainly constitute by brake-applying handle, rear brake main pump, oil pipe and rear brake etc., just size adjusts, correspondingly brake-applying handle is also done for a short time, thereby brake-applying handle is just little to the arm of force between the rear brake main pump, according to mechanics principle, reach corresponding braking force, the power that is applied on the brake-applying handle is just very big, and this can feel to require great effort very much for children.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of children of rapid operation to use the beach buggy post brake device.
For this reason, children described in the utility model use the beach buggy post brake device, comprise brake-applying handle, rear brake main pump, oil pipe and rear brake, rear brake main pump links to each other by oil pipe with rear brake, brake-applying handle links to each other with an end of brake control lever by brake cable pull, the other end of brake control lever is hinged on the rear brake main pump housing by pin, and is provided with haptic element on brake control lever, and this haptic element contacts with trigger head on the rear brake main pump.
Above-mentioned brake control lever link to each other with brake cable pull one is a U-shaped fork structure, between this U-shaped fork two side pin is installed, and has vertically passed the threaded adjusting bar on the pin, and an end of this threaded adjusting bar links to each other with brake cable pull.
Between brake-applying handle and rear brake main pump, set up brake cable pull and brake control lever in the utility model, brake cable pull is used for transmission power, brake control lever is used for increasing the arm of force, according to mechanics principle, lock torque=hand grip control power * arm of force, the long more braking force that is applied on the brake-applying handle of the arm of force is just more little under the identical condition of required lock torque, thereby more laborsaving, is highly suitable on children's beach buggy and uses.
The beneficial effects of the utility model are: rapid operation, convenience, and little to the structural modification of whole brake equipment, do not influence the integral structure of car.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view (part).
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1 and Figure 2, children described in the utility model use the beach buggy post brake device, form by brake-applying handle 1, rear brake main pump 2, oil pipe 3, rear brake 4, brake cable pull 5 and brake control lever 6, rear brake main pump 2 links to each other by oil pipe 3 with rear brake 4, brake-applying handle 1 links to each other with an end of brake control lever 6 by brake cable pull 5, the other end of brake control lever 6 is hinged on rear brake main pump 2 housings by pin 9, and on brake control lever 6, being provided with haptic element 6a, this haptic element 6a contacts with trigger head 2a on the rear brake main pump 2.
Can find out from Fig. 1, Fig. 2: brake control lever 6 link to each other with brake cable pull 5 is a U-shaped fork structure, between this U-shaped fork two side pin 7 is installed, and has vertically passed threaded adjusting bar 8 on the pin 7, and an end of this threaded adjusting bar 8 links to each other with brake cable pull 5.Threaded adjusting bar 8 is used for regulating the degree of tightness of brake cable pull 5.
Glancing impact is held brake-applying handle 1, and it is that run-on point is rotated with pin 9 that brake-applying handle 1 drives brake control lever 6 by brake cable pull 5 and threaded adjusting bar 8, so the haptic element 6a on the brake control lever 6 promotes the trigger head 2a on the rear brake main pump 2, makes rear brake main pump 2 work.
