Description
Technical field
The utility model relates to a kind of rear wheel seat structure of pushchair.
Background technology
Pushchair is a kind of common tool of carrying child, need brake when descending or when running into roadblock.The mode of hand-operated brake is adopted in traditional brake mostly, unexpected brake may generate a panic and uncomfortable sensation to the child, also can adopt the mode of foot-propelled brake, but often during the foot-propelled brake user's reaction can hesitate to some extent, equally also can generate a panic to the child.And existing pushchair, car pin pipe and rear wheel seat position are generally and are rigidly connected, and press down when ride is walked or when being subjected to gravity, can bring sudden surge power to the child, even damage to the child.The rear wheel seat structure of present pushchair is installed and removed also very inconvenient.
Summary of the invention
The purpose of this utility model is for a kind of rear wheel seat structure of easy to use and safe pushchair is provided.
The main technical schemes that the utility model adopts is: this rear wheel seat mechanism comprises hand-operated brake assembly, foot-propelled brake assemblies, quick detach button and damping spring; The locating dowel pin that is fixed together with the quick detach button passes wheel seat and pipe spreader and fixedly places wheel shaft in the pipe spreader; Damping spring places in the middle of the two ends, the trailing wheel seat of honour.
Described hand-operated brake assembly comprises drawing article, the drag-line that links to each other with drawing article, be fixed on the wheel and contain the brake tooth of a plurality of knock holees and be looped around that the brake tooth is peripheral to leave the brake ring in gap with the brake tooth, and drag-line is connected with brake ring.
Be installed in the described foot-propelled brake assemblies to be provided with in the permanent seat on the pipe spreader and be subjected to the brake sliding pin of brake pedal control to two lateral movements; Limit spring is provided with pull back spring between the other end of brake lever and the vehicle frame between brake sliding pin and brake lever, brake lever matches with knock hole.
In the utility model, the brake of hand-operated brake and foot-propelled can be carried out simultaneously, coats the brake tooth by brake ring during hand-operated brake, produces friction and plays deceleration effort, can not produce because emergency brake and do not accommodate fear to what the child caused.The function of fixing brake is played in the foot-propelled brake.Owing to settled damping spring in the trailing wheel seat of honour, past pressing down when ride walk or when being subjected to gravity with the elastic buffer of spring, prevents the impact between battle array and causes child's sense of discomfort.This uses novel easy to use and safe.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the rear wheel seat mechanism of the pushchair in the present embodiment comprises hand-operated brake assembly, foot-propelled brake assemblies, quick detach button 16 and damping spring 7; Braking mechanism is made up of hand-operated brake assembly and foot-propelled brake assemblies, described hand-operated brake assembly comprises drawing article 1, the drag-line 2 that links to each other with drawing article 1, be fixed on the wheel and contain the brake tooth 3 of a plurality of knock holees 31 and be looped around that brake tooth 3 is peripheral to leave the brake ring 4 in gap with brake tooth 3, and drag-line 2 is connected with brake ring 4; Be installed in the described foot-propelled brake assemblies to be provided with in the permanent seat 10 on the pipe spreader 9 and be subjected to the brake sliding pin 5 of brake pedal 11 controls to two lateral movements; Limit spring 6 is provided with pull back spring 8 between the other end of brake lever 7 and the vehicle frame between brake sliding pin 5 and brake lever 7, brake lever 7 matches with knock hole 31.
In the present embodiment, described knock hole 31 is the center regular distribution with wheel shaft 12; Described brake lever 7 is two and left-right symmetric distribution.
As Fig. 4, shown in Figure 5, the locating dowel pin 14 that is fixed together with quick detach button 16 passes wheel seat 13 and pipe spreader 9 and fixedly places wheel shaft 12 in the pipe spreader 9.One end of wheel shaft 12 has the groove 121 that matches with locating dowel pin 14.
As shown in Figure 1, damping spring 17 places in the middle of 19 two ends, the trailing wheel seat of honour.Rear foot tube 18 sleeves play the effect of transmission power at an end at the trailing wheel seat of honour 19.Damping spring 17 toward pressing down, with the elastic buffer of spring, prevents that impact between battle array to the sense of discomfort that the child forms, playing the effect of damping when ride is walked or when being subjected to gravity.
The working process of whole braking mechanism is made up of hand-operated brake assembly working process and foot-propelled brake assemblies working process, and the working process of hand-operated brake assembly and foot-propelled brake assemblies can be to finish synchronously also asynchronously to finish.
The working process of hand-operated brake assembly is as follows: when ride normally moves, be fixed on the brake tooth 3 on the wheel and coat between the brake ring 4 of brake tooth 3 fixed gap is arranged, when needing deceleration ride running velocity, pulling drawing article 1, the drag-line 2 that drive links to each other with drawing article 1, drag-line 2 is fixedly linked with an end of brake ring 4, pulling brake ring 4, brake ring 4 is drawn and is held tightly brake tooth 3, produces friction and plays deceleration.Be covered with a plurality of knock holees 31 in the middle of the brake tooth 3, knock hole 31 is the center regular distribution with wheel shaft 12.
The working process of foot-propelled brake assemblies is as follows: when ride normally moves, one section space is arranged between brake lever 7 and the knock hole 31.Step on brake pedal 11, brake lever 7 is moved to both sides.When brake pedal 11 is stepped on, when the knock hole 31 on brake lever 7 and the brake tooth 3 does not have contraposition, brake pedal 11 still can be floored, this moment limit spring 6 braked sliding pin 5 pressure and compress, when brake tooth 3 forwards to brake lever 7 contrapositions, brake lever 7 ejects at the yield force that is subjected to limit spring 6, reaches the function of brake.Brake lever 7 is two and left-right symmetric distribution.When the needs ride moves once more, loosen brake pedal 11, pull back spring 8 pulling brake lever 7, brake lever 7 breaks away from knock holees 31 at this moment, but ride free-running operation.
The working process of whole fast removable member is as follows: wheel shaft 12 is enclosed within the pipe spreader 9, and wheel seat 13 envelopes pipe spreader 9, and the annular groove 121 that matches with locating dowel pin 14 tops is arranged in the wheel shaft 12, and quick detach button pull back spring 15 is placed between pipe spreader 9 and the wheel seat 13.When locating dowel pin 14 was passed wheel seat 13 and pipe spreader 9, locating dowel pin 14 compression quick detach button pull back springs 15 passed through bolt together with locating dowel pin 14 and quick detach button 16 simultaneously, and this moment, locating dowel pin 14 and groove 121 interlock mutually were fixed on wheel on the ride; The outward winding bolt of fixed locating stud 14 and quick detach button 16 because the effect of the restoring force of quick detach button pull back spring 15 ejects locating dowel pin 14, spins off locating dowel pin 14 from groove 121, so just wheel can be pulled down from ride.
