Description

Technical Field

[0001] The invention relates to the technical field of baby carriages, in particular to a baby carriage with an adjustable seat. Background Art

[0002] A child stroller is a commonly used device for infants and young children. It is convenient for infants and young children to sit on the seat of the stroller, and the parents can move the stroller by pushing it. Most of the existing seats are fixed, and the children sitting on the seats are facing forward or toward the parents, which is difficult to meet the use requirements at multiple angles. Therefore, seats that can be adjusted and rotated on strollers have appeared to meet the use requirements, but the adjustment methods mostly require complex buckle locking structures. Parents cannot quickly adjust them during use and need to spend a lot of effort. Simple rotating structures have poor stability for the seat. Therefore, it is necessary to design a child stroller that saves effort and can be quickly adjusted with one hand to achieve 360-degree rotation of the seat, with good structural stability to meet the existing use requirements.

[0003] The Chinese patent with the announcement number CN115817615A discloses a child stroller with a 360-degree quickly adjustable seat, which includes a frame, a seat and a foot pedal. The frame is provided with a support seat and at least two card interfaces. The seat includes a base, a rotating seat, an adjustment member and a lock member. The base is rotatably mounted on the support seat through the rotating seat. The base is provided with an adjustment groove, a movable seat and a rotating seat. The adjustment member is movably mounted in the adjustment groove. The movable seat is arranged in the adjustment groove and is provided with a movable opening aligned with the card interface. The lock member is movably mounted on the movable seat, and its bottom passes through the movable opening and is engaged with the card interface to limit the rotation of the base. The foot pedal is rotatably mounted on the rotating seat and is provided with an adjustment part for pushing the adjustment member to adjust the lock member to engage or disengage the engagement. The present invention realizes that the seat can be quickly adjusted with one hand, so that it can be rotated 360 degrees on the stroller, has good structural stability, and meets the existing use requirements.

[0004] However, the above disclosed solution has the following shortcomings: the above solution can be easily assembled and connected through the locking structure when in use, but the above device has a general limiting effect on children when in use, so there is a risk of children accidentally falling during the pushing process.

[0029] The following is combined with Figure 1-4 The present invention is described in further detail.

[0030] Embodiment 1

[0031] like Figure 1-Figure 4 As shown, in order to solve the existing problems, the present invention discloses a child stroller with an adjustable seat in this embodiment, including a roller bracket 1 and a support wheel 2 rotatably connected to the bottom thereof, a support component 3 is connected to the top of the roller bracket 1, a pressing component 4 is connected to the side of the support component 3, a seat 5 is rotatably connected to the side of the support component 3, a tilting component 6 is rotatably connected to the side of the seat, and a brake component 8 is connected to the bottom of the roller bracket 1.

[0032] The support component 3 includes an elastic telescopic rod 301 connected to the side of the roller bracket 1, the other end of the elastic telescopic rod 301 is connected to a connecting piece 302, the side of the connecting piece 302 is rotationally damped and connected to a rotating support 303, and the other end of the rotating support 303 is rotationally connected to a roller 304.

[0033] The pressing component 4 includes a damping telescopic rod 401 connected to the side of the connecting member 302, the other end of the damping telescopic rod 401 is connected to a rotating connecting member 402, the side of the rotating connecting member 402 is rotationally damped and connected to a rotating rod 403, and the other end of the rotating rod 403 is connected to a pressing rod 404.

[0034] The tilting component 6 includes a rotating connecting rod 601 rotatably connected to the side of the seat 5, the other end of the rotating connecting rod 601 is rotatably connected to a sliding bracket 602, the other end of the sliding bracket 602 is provided with a sliding groove 603, the inner wall of the sliding groove 603 is slidably connected to a locking piece 604, and the locking piece 604 is threadedly connected to the roller bracket 1.

[0035] The roller bracket 1 is connected to a handrail 7 on the side, and the brake component 8 includes a rotating shaft 801 that passes through and is rotatably connected to the side of the roller bracket 1, and the rotating shaft 801 is connected to the side of the support wheel 2. The roller bracket 1 is connected to a clamping member 802 on the side away from the support wheel 2, and one end of the clamping member 802 is connected to a sliding member 803, and the other end of the clamping member 802 is connected to a fixing member 804, the sliding member 803 is slidably connected to the side of the roller bracket 1, and the fixing member 804 is connected to the side of the roller bracket 1.

[0036] The specific working principle is: the device can effectively improve the use efficiency of the baby stroller, reduce the difficulty of using the baby stroller, and ensure the fixation of the child on the baby stroller, thereby reducing the risk of the child falling accidentally.

[0037] When the device is in use, the armrest 7 can facilitate the device to be pushed and used. At this time, the support wheel 2 and the roller 304 are in contact with the ground, thereby achieving the pushing effect of the device. After the child sits on the seat 5, the distance between the pressing rod 404 and the child can be adjusted by pulling the damping telescopic rod 401.
