Abstract

本实用新型公开了一种螺杆旋进式推拉门锁,该锁将锁芯制成螺杆旋进式,在螺杆的头部装配一只手轮,便于操作,在门框的部位用一个挡片固定,该挡片内螺杆通过部位有相匹配的内螺纹,便于安装操作。

Description

所属技术领域
本实用新型涉及一种推拉门锁,尤其是螺杆旋进式推拉门锁。
背景技术
目前,公知技术的推拉门锁是在两扇推拉门之间,安装一只已申请中国专利的搭扣式推拉门锁,该锁由于设计合理美观,已经垄断了整个市场,但是该锁也存在着缺点,例如搭扣在旋入部位仅仅只有半圈,在安全防护上存在着不牢固,容易发生小偷撬门而入的隐患。
发明内容
为了克服现有的搭扣式推拉门锁存在着不牢固的隐患,本实用新型的目的是为了提供一种螺杆旋进式的推拉门锁,该锁锁芯直接与推拉门的门框中心部位用螺杆旋进,其长度可以达到具有非常安全感的尺寸,同时安装制作比较方便。
本实用新型解决其技术问题所采用的技术方案是:将锁芯制成螺杆旋进式,在螺杆的头部装配一只手轮,便于操作,在门框的部位用一个挡片固定,该挡片内螺杆通过部位有相匹配的内螺纹,便于安装操作。
本实用新型的有益效果是比较牢固,制作成本比较低廉。实用性较强。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型示意图。
图中1.手轮,2.螺杆,3.外门框挡片安装孔,4.外门框挡片(螺杆通过部位有相匹配的内螺纹),5.内门框挡片安装孔,6.内门框挡片(螺杆通过部位有相匹配的内螺纹)。
具体实施方式
按图1将外门框挡片4(螺杆通过部位有相匹配的内螺纹)安装在外门框上,把外门框挡片安装孔3进行固定,将内门框挡片6(螺杆通过部位有相匹配的内螺纹)安装在内门框上,把内门框挡片安装孔5进行固定,把螺杆2用手轮1旋入外门框挡片4(螺杆通过部位有相匹配的内螺纹)内,长时间的旋入可将螺杆进入内门框挡片6(螺杆通过部位有相匹配的内螺纹)而达到锁定的作用。

Claims (2)

1、一种螺杆旋进式门锁,包括外门框挡片4,内门框挡片6,其特征在于锁芯制成螺杆旋进式;
2、权利要求1所述的一种螺杆旋进式门锁,包括外门框挡片4,内门框挡片6,其特征在于外门框挡片4与内门框挡片6中螺杆通过部位有相匹配的内螺纹。
