Description

能自动锁紧的拉链头
技术领域
本实用新型属一种拉链头，具体涉及一种能自动锁紧的拉链头。
背景技术
拉链头主要由前头体(2)，后头体(5)和与前头体铰链连接的拉牌(4)组成，为了锁定被拉链头拉合的链齿，使其不致脱开，很多拉链头上设有锁定部件，现有能自动锁紧的拉链头主要结构是在拉牌的铰链轴上装有扭簧，在前头体上装有锁紧弹片，拉合链齿后，拉牌在扭簧的作用下自动向前头体合拢，并压下前头体上的锁紧弹片，使弹片压到到啮合的链齿上，锁定链齿使其不致脱开。这种结构的拉链头不易加工。
发明内容
本实用新型要解决的技术问题是提供一种结构简单，易于加工的能自动锁紧的拉链头。
解决上述问题的技术方案是(参见实施例图)：本实用新型设有前头体(2)、后头体(5)、拉牌(4)，拉牌与前头体铰链连接，铰链部位装有作用于拉牌的扭簧(8)，其特征在于，在所述前头体上设有前后连通的插孔(7)，在拉牌(4)后壁面上对着插孔(7)的部位设有凸起的锁定销(6)。
本实用新型的工作原理是：用拉链头将夹在前头体(2)和后头体(5)之间的链齿拉合后，释放拉牌(4)，拉牌在扭簧的作用下自动复位，向前头体靠拢，其上的锁定销(6)随之插入前头体的插孔(7)内，锁定销端头穿过插孔(7)顶住夹在前头体和后头体之间的链齿(1)，使其不能脱开，起到自动锁紧的作用。
本实用新型具有结构简单，易于加工的优点。
