The invention discloses a wheel mounting seat, a baby carriage frame and a baby carriage, the wheel mounting seat comprises a limiting part, a connecting part and a clamping part, the connecting part comprises a first abutting part and a second abutting part, the first abutting part and the second abutting part are both connected to one side of the limiting part, a deformation gap is limited between the first abutting part and the second abutting part, and the clamping part is clamped in the first abutting part and the second abutting part. The first abutting part and the second abutting part are both suitable for abutting against the inner wall of the supporting pipe, so that the connecting part is suitable for being in interference fit with the supporting pipe. The connecting part is inserted into the end of the supporting pipe, the first abutting part and the second abutting part deform in the direction close to each other and abut against the inner wall of the supporting pipe under the action of elasticity of the first abutting part and the second abutting part, and the first abutting part and the second abutting part both have certain deformation capacity. Under the condition that the supporting pipe of the frame body deforms to a certain degree in the processes of welding, spraying and the like, the connecting part can still be smoothly arranged in the supporting pipe, the frame body does not need to be manually trimmed or scrapped, and the production cost is reduced.
本申请公开了一种车轮安装座、婴儿车架及婴儿车,其中车轮安装座包括限位部、连接部及卡接部,连接部包括第一抵接部及第二抵接部,第一抵接部、第二抵接部均连接于限位部的一侧,第一抵接部与第二抵接部之间限定有形变间隙,第一抵接部与第二抵接部均适用于抵接于支撑管的内壁,以使连接部适用于与支撑管过盈配合。将连接部插入支撑管的端部,第一抵接部与第二抵接部向相互靠近的方向发生变形,且在自身弹性的作用下抵紧支撑管的内壁,由于第一抵接部与第二抵接部均具有一定的形变能力,在架体的支撑管在焊接、喷涂等工序发生一定程度的变形的情况下,连接部仍能顺利装入支撑管中,无需人工对架体进行修整,或报废架体,有利于降低生产成本。
