Abstract

本实用新型提供了一种改进的门扣。包括扣座,通过铰轴与扣座铰接的扣板,其特征是铰轴轴心线与扣座纵向间的夹角40°≤α≤50°。安全,使用寿命长。

Description

门扣
本实用新型涉及的是一种改进的门扣。
已有的直线型门扣在使用过程中,如开门后,扣板和扣座不易重合面形成扣板向外斜伸,易挂环衣物或伤人,而关门时如扣板伸在门边缘处易造成扣板、扣座损坏,影响其使用寿命。
鉴于以上原因,本实用新型的目的为了提供一种安全,使用寿命长的门扣。
本实用新型的目的是这样来实现的:
本实用新型是在已有的门扣的基础上的改进,包括扣座,通过铰轴与扣座铰接的扣板,其特征是铰轴轴心线与扣座纵向间的夹角40°≤α=50°
上述的∠α=45°,扣板横向与铰轴轴心线间的夹角β=45°。
本实用新型安装在门上,开门时,扣板因其自身的重力自动落下,不会损坏衣物或伤人,关门时也不会出现扣板伸在门边缘上面损坏扣座、扣板。
本实用新型安全,使用寿命长。
下面结合附图详细说明本实用新型的实施例:
图1为本实用新型结构示意图。
参见图1,扣板1通过铰轴2与扣座3铰接。铰轴轴心线L与扣座上纵向间的夹角α=45°。扣板横向与铰轴轴心线间的夹角β=45°。

Claims (2)
