Abstract

一种由固定板、锁壳和扣襻等构成的合紧锁，为了防止被别人用扳手、钳子等工具开锁，本实用新型一种合紧锁的配匙体采用截面呈椭圆形的突体。该合紧锁固定板上联有锁舌，锁芯上联有锁片，锁片上联有转动复位弹簧。该锁结构简单，使用方便，保安性强。

Description

一种合紧锁
本实用新型涉及特殊用途的锁，特别是搭扣锁。
将摇转门或移动门关闭拉合后锁紧所用的合紧锁，其锁芯配匙体大多采用截面为六边形、四边形或三角形的突体，配合套入钥匙的转动而产生扭矩。锁芯上这种形状的配匙体，容易被别人用扳手、钳子等工具扭转而打开锁，降低了门锁的保安性。
本实用新型的目的在于克服上述缺陷、提供一种合紧锁，这种锁不容易被别人用常规工具打开。
本实用新型一种合紧锁有一固定板，该固定板与锁壳的一端铆接，锁壳与扣襻铆接，一锁片联于锁芯，该锁片上联有转动复位弹簧，与锁芯相联的配匙体为截面呈椭圆形的突体外露于锁壳。
本实用新型由于采用截面呈椭圆形的突体作配匙体，故不容易被别人用扳手、钳子等常规工具打开，提高了锁的保安性。
下面结合附图和实施例进一步说明本实用新型的技术方案。
图1为本实用新型一种合紧锁的立体示图；
图2为锁体结构的一种示图；
图3为图2的A—A剖示图。
由附图可见，该合紧锁有一固定板1，固定板1两侧连有锁舌2，锁壳13的一端通过铆钉5套联于固定板1，扣襻4通过铆钉6套联于锁壳13，压簧7缠扣于铆钉5和铆钉6，锁片11与锁心相联，锁片11上联有扭簧9，截面呈椭圆形的配匙体14与锁芯相联外露于锁壳13，用于开锁的钥匙15其套孔截面呈椭圆形与配匙体14配合。
该锁可用于摇转门或移门的拉紧锁合。以移门A和移门B为例，固定板1固定于移门A一边，在锁壳13向固定板1扣合时，扣襻4外端扣拉住移门B一边，锁壳13合上时，固定板1两侧的锁舌2扣住锁片11的两肩10、12，将移门A和移门B相对拉紧并锁合。开启时，用钥匙15套于配匙体14，按图2锁壳所标箭头方向转动，锁片11与锁舌2脱钩，压簧7将锁壳13顶开。孔3和孔8可用于锁合时置挂锁。
