Description

Technical Field

[0001] The utility model relates to the technical field of baby carriages, in particular to a brake assembly for a baby carriage. Background Art

[0002] A baby stroller is a stroller specially designed for transporting babies, allowing them to sit, lie down, or rest in the stroller, replacing the previous baby carrier or cradle. Old baby strollers cannot be folded, but later foldable baby strollers were developed so that they can be put into the trunk of a car for easy transportation. The front wheels of a baby stroller are generally universal wheels, which makes it easier for the stroller to turn, while the two rear wheels are synchronously turned, and the brake components are generally set on the two rear wheels.

[0003] At present, when the brake assembly of a baby stroller is actually used, it is generally controlled by pedaling. When braking is needed, the brake pedal is stepped on with the foot, and the brake pedal rotates to drive the brake pin to lock the wheel. When unlocking is needed, the brake pedal is lifted up with the instep, and the brake pedal rotates in the opposite direction, thereby achieving brake unlocking. However, the structural method of driving the brake pedal to rotate and unlock by lifting the brake pedal upward with the instep is laborious and inconvenient to operate. Long-term operation may also scratch and damage the shoes. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figures 1 to 8 A baby carriage brake assembly is shown, comprising:

[0029] A connecting crossbar 1, both ends of which are connected to wheels 2, a push rod 3 is fixedly provided at the outer end of the middle of the connecting crossbar 1, and a handle 4 is fixedly connected to the top of the push rod 3;

[0030] An L-shaped adjusting rod 5 is arranged on the inner side of the wheel 2. An adjusting groove 6 is provided at both ends of the connecting cross bar 1. The top of the vertical portion of the L-shaped adjusting rod 5 extends into the adjusting groove 6. Two first fixing plates 7 and a second fixing plate 8 are fixedly provided inside the connecting cross bar 1. The first fixing plate 7 and the second fixing plate 8 are respectively arranged at both ends of the adjusting groove 6. A limiting block 10 is fixedly provided at one end of the transverse portion of the L-shaped adjusting rod 5. A limiting toothed disc 11 is fixedly provided on the inner side of the wheel hub of the wheel 2. The tooth groove size of the limiting block 10 corresponds to that of the limiting toothed disc 11.

[0031] Spring 12, both ends of the spring 12 are fixedly connected to the outer side of the second fixed plate 8 and the inner side of the vertical part of the L-shaped adjusting rod 5, respectively. Two fixed guide rods 9 are fixedly arranged between the first fixed plate 7 and the second fixed plate 8. The two fixed guide rods 9 are respectively arranged at the top and bottom of the spring 12. One ends of the two fixed guide rods 9 both pass through the vertical part of the L-shaped adjusting rod 5. A pull rope 13 is fixedly arranged on the inner side of the vertical part of the L-shaped adjusting rod 5. One end of the pull rope 13 passes through the inside of the spring 12, the second fixed plate 8, the inside of the connecting cross bar 1 and the inside of the push rod 3 in sequence and extends to the inside of the handle 4.

[0032] A rotating winding rod 14 is provided inside the handle 4, and two ends of the rotating winding rod 14 pass through the two ends of the handle 4 respectively and are rotatably connected between the two ends of the handle 4. One end of the pull rope 13 is wound around the outer end of the rotating winding rod 14 and is fixedly connected between the outer ends of the rotating winding rod 14. Two redirecting rods 15 are rotatably connected inside the connecting cross bar 1. The redirecting rod 15 is arranged at the bottom end of the push rod 3, and the pull rope 13 passes around the outer end of the redirecting rod 15.

[0033] A rotating connecting column 16 is fixedly provided at both ends of the rotating winding rod 14. The outer diameter of the rotating connecting column 16 is the same as the outer diameter of the handle 4. A first T-slot 17 is provided on the outer side of one end of the rotating connecting column 16. A T-block 18 is provided inside the first T-slot 17. The T-block 18 and the first T-slot 17 have an interference fit. The top of the T-block 18 is provided with anti-slip stripes. Second T-slots 19 with the same size as the first T-slot 17 are provided at both ends of the handle 4. The second T-slot 19 is provided at one end of the T-block 18.

[0034] When pushing the baby carriage to walk, the rotating connecting column 16 and the rotating winding rod 14 are rotated, and the rotating winding rod 14 winds the pull rope 13, and the pull rope 13 drives the L-shaped adjustment rod 5 and the limit block 10 to move inward. The L-shaped adjustment rod 5 will compress the spring 12. At this time, one end of the T-block 18 is pushed into the second T-slot 19. The T-block 18 will limit the rotating connecting column 16 and the handle 4 together. When the baby carriage needs to be braked, the T-block 18 is pushed into the first T-slot 17. The T-block 18 releases the connection limit between the rotating connecting column 16 and the handle 4, and the rotating connecting column 16 and the rotating winding rod 14 are rotated. The pull rope 13 wound on the rotating winding rod 14 will be released outward. At this time, the L-shaped adjusting rod 5 will move outward under the elastic force of the spring 12, and the L-shaped adjusting rod 5 will drive the limiting block 10 to be inserted into one of the tooth grooves on the limiting toothed disc 11. The limiting block 10 and the L-shaped adjusting rod 5 will limit the limiting toothed disc 11 and the wheel 2, so that the stroller can be braked.

[0035] The utility model uses the pull rope 13 to pull the L-shaped adjusting rod 5 and the limit block 10 to move, and the spring 12 drives the L-shaped adjusting rod 5 and the limit block 10 to reset, so that the adjustment of the wheel 2 to release the brake and start the brake can be realized, so that the braking process of the baby stroller is more convenient, and the braking process can be manually controlled, avoiding the situation that the shoes of the person are damaged during the adjustment of the brake structure, and the use effect is better. This embodiment specifically solves the problem that the baby stroller brake assembly existing in the prior art is generally controlled by foot pedaling in actual use. When braking is needed, the brake pedal is stepped on with the foot, and the brake pedal rotates to drive the brake pin to lock the wheel. When unlocking is needed, the brake pedal is lifted up with the instep, and the brake pedal rotates in the opposite direction to realize brake unlocking. However, the structural method of relying on the instep to lift the brake pedal upward to drive the brake pedal to rotate and unlock is laborious and inconvenient to operate. Long-term operation will also scratch the shoes and damage the shoes.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
