Abstract

一种束紧环,开口环的缺口两边有片状夹头,夹头背面两侧有垂直的侧板,使夹头背面形成可藏入固紧螺栓端头的凹台。所述的束紧环,其夹头、侧板可是同一块板材,可冲压而成,成本低。侧板实际是加强筋板,其刚性好,可承受大夹持力。夹头背面的凹台可藏入螺栓端头,无突出的故障物美观。

Description

一种束紧环
本实用新型涉及将两个相套叠的管件箍紧的束紧环。
一个管插入另一个管中相套叠,既需要可调整插入的深度,又要在调整之后使两管相互位置固定。例如自行车的车座立管插入车架立管中。这类两管套叠的配合还有很多应用,一般均用束紧环将两管箍紧使之固定。束紧环是一个开有缺口的圆环,缺口两边各有一个可贯穿螺栓的夹头。夹头可以是与圆环连为一体的片状物,也可以是在缺口两边固定的实体夹块。片状夹头的束紧环刚性较差、不适于夹紧力较大的应用,但可冲压而成,成本低;块状夹头的束紧环刚性好、夹持力大,但制做成本偏高。另外,螺栓贯穿夹头,则夹头两侧突出螺栓的端部,既不美观且形成了管接头附近的突出障碍物。如自行车座下束紧环的横向突出物对放在车尾架上的物品,甚至对骑行者都可能是一种潜在的不安全因素。
本实用新型之目的是给出一种可承受大夹持力,成本低,且夹紧后无明显突出障碍物的束紧环。
本实用新型所述的束紧环,开口环的缺口两边有片状夹头,片状夹头的两侧固定与夹头垂直的侧板,使夹头的背面形成可藏入固紧螺栓端头的凹台。
所述的束紧环,其夹头是片状,侧板也是片状,夹头与侧板可以是同一块板材,仍可冲压而成,生产成本低。侧板的后部可与圆环焊接固定,侧板则成为加强筋板,使束紧环刚性明显加强,因而可承受很大的夹持力。另外,在夹头背面形成了凹台,固紧螺栓的端头处于凹台中,无明显的突出障碍物,既美观又消除了突出物造成的潜在不安全因素。
图1束紧环的装配关系立体图;
图2束紧环的装配关系立体图;
图3是图2的使用状态剖视图。
实施例一  如图1
开口环1的缺口两边有片状夹头2,夹头2两侧固定与夹头垂直的侧板3,使夹头2的背面形成凹台4。固紧螺栓当然可以使用常规的螺钉、螺母。螺母卡入凹台4中不可转动,使用内六角螺钉或尾端有槽的螺钉固紧。本实施例给出凸轮压柄固紧方式则较佳;固紧螺栓6拉紧端铰接凸轮压柄5,螺栓6另一端装可调节有效长度的螺母7。
实施例二  如图2、3
实施例一的压柄5的凸轮5b部分直接与夹头2摩擦,因而对夹头2和凸轮5b的材质要求较高,致使成本偏高。本实施例的固紧螺栓6的拉紧端开有横向的偏心孔8,孔中穿入偏心销9,偏心销与手柄5a固连,即与手柄5a转动角度相同。仅螺栓6和偏心销9两个摩擦件的材质要求较高,对整个束紧环的成本影响甚微。其余与实施例一相同。
