Description

一种自行车用龙头套筒、自行车前筐固定结构及自行车 技术领域
本实用新型属于自行车技术领域，具体涉及一种自行车用龙头套筒、自行车前筐固定结构及采用该龙头套筒和自行车前筐固定结构的自行车。
 背景技术
为了方便骑行者骑行过程中放置物品，在自行车前部安装车筐是一种常见结构。现有自行车前筐安装固定方式通常通过两个固定部进行安装固定：下固定部和上固定部。其中，下固定部设置在前筐底部，通过前筐底部连接件与前轮的中心轴连接固定，上固定部设置在车筐的朝向车龙头这一侧，通过该朝向车龙头侧的连接件与车龙头转轴固定。
一种常见的前筐底部连接件为一个安装架，该安装架两侧分别固定连接在前轮中心轴两侧。朝向车龙头侧的前筐连接件的一种常见结构为一个连接片，如图1所示，该连接片一端开有圆孔，套在车龙头转轴上，另一端设有与连接片垂直的连接端，该连接端采用螺丝螺母与前筐固定。
自行车龙头转轴位于车架前端的龙头套筒内，龙头转轴下部延伸端与前轮连接。自行车龙头转动方向时，通过龙头转轴带动前轮转动，前筐通过与前轮连接的前筐底部安装架和龙头转轴相连的前筐连接件而发生同向转动。
将前筐通过连接件直接连接固定在龙头转轴上，虽然连接方式简单、生产成本低，但这种前筐固定结构存在如下问题：当车筐内物品重量较重时，比如，将一大袋水果或一只大背包放进前筐里，由于靠近车龙头侧的前筐连接件是固定连接在车龙头转轴上的，前筐里物品会把重量施加在自行车龙头上，会影响车龙头转向，特别是在车龙头转弯或轻微转动方向时，车龙头的转向不仅笨重、不灵活，而且转向不稳定。对于车技不高、气力小的骑行者，如学生、有些女士等，这样的前车筐固定结构设计不仅会让骑行者骑车更费劲，还会因为转向不灵活、不稳定，给骑行者带来安全问题。
 技术问题
鉴于现有技术上述缺陷，本申请人对自行车车筐固定结构进行了改良，将前筐连接到与车架连接的龙头套筒上，这样，可由龙头套筒分担前筐物品的重量，使得龙头转向更轻巧、灵活、稳定。
 技术解决方案
为此，本实用新型的第一目的是提出一种自行车龙头套筒，其采用如下技术方案：
一种自行车用龙头套筒，所述龙头套筒上设有可与其转动配合并用于安装前筐的第一连接部。
一种实施例中，所述第一连接部为套设在所述龙头套筒上并与龙头套筒转动配合的连接件。
进一步的，所述连接件与所述龙头套筒之间设有轴承。
一种实施例中，所述第一连接部为弧形轨道。
进一步的，所述第一连接部还包括与弧形轨道呈滑动配合并用于连接前筐的前筐连接件。
进一步的，所述弧形轨道为设置在所述龙头套筒外周壁上的燕尾型凹槽或燕尾型滑块，所述前筐连接件设有与所述燕尾型凹槽或燕尾型滑块呈滑动配合的燕尾型滑块或燕尾型凹槽。
进一步的，所述弧形轨道与龙头套筒同轴设置。
本实用新型第二目的在于提供一种自行车前筐固定结构，用于固定前筐，其包括：前筐安装架，所述前筐安装架的上端用于与前筐连接，下端用于与前轮连接；还包括前面任一项所述的龙头套筒。
本实用新型第三目的在于提供一种自行车，其包括车架，所述车架前端设有前面任一项所述的龙头套筒。
本实用新型第四目的在于提供一种自行车，其包括车架、前筐，还包括前面任一项所述的自行车前筐固定结构，所述龙头套筒位于车架前端，所述前框通过所述第一连接部与所述龙头套筒连接。
 有益效果
将自行车龙头套筒和自行车前筐固定方式按本实用新型实施例的技术方案进行改造，使用时，将前筐通过第一连接部和龙头套筒连接，由于第一连接部和龙头套筒之间为转动配合，使得前框可绕龙头套筒旋转，此种连接方式与将前筐通过连接部直接连接到龙头转轴的连接方式相比，所产生的技术效果是非常突出的：
1、采用本实用新型实施例的技术方案，对前筐的固定和转动，没有任何消极影响；
2、采用本实用新型实施例的技术方案，可将前筐物品重量转移到龙头套筒上，能大大减轻龙头的重量，可使龙头变轻，在转动自行车的龙头把手时，会更加灵活、轻巧，稳定性也更好。这是本实用新型技术方案的最大优点所在。
3、将前筐物品重量转移到龙头套筒上，可进一步将重量通过龙头套筒转移到与龙头套筒连接的车架整体上，其效果相当于车架自身重量加重了，给龙头转轴的重量大大“减负”了，可以很好地分担前筐物品重量。
4、通过将前筐的固定连接部由龙头转轴下移到龙头套筒上，可将前筐的固定部降低，也可以达到减轻龙头转轴负荷的效果。
