The invention discloses an anti-theft fastening door pin for door opening, including a door pin hole unit and a door pin plate unit; the door pin hole unit includes a base plate and a pin hole plate installed on the base plate, and the pin hole plate is provided with a pin hole; the door pin plate unit includes a plate body, a pin block and a hanging pin; the pin block is a vertical plate installed on the plate body, and the vertical plate is provided with a hanging pin hole; the hanging pin includes a lower pin arm, a middle pin arm and a pin One end of the lower pin arm is connected to the pin stop through the rotating shaft, the other end is hinged with one end of the middle pin arm, the other end of the middle pin arm is hinged with one end of the pin rod, the other end of the pin rod is free end, which is connected to the pin hole, and the hanging pin is connected to the pin stop through the reset structure. The invention locks the door by the way that the hanging pin enters the pin hole from the direction pin of the door pin hole unit and further pins the hanging pin hole, which solves the problem that the hanging pin is not opened from the door seam by people. In addition, because the hanging pin enters the pin hole from the direction pin of the door pin hole unit, it also provides the relative tension for the opposite door opening, which solves the risk of the ordinary door pin slipping directly in case of violent door kicking.
【技术实现步骤摘要】
一种对开门的防盗紧固门销
本专利技术涉及锁具
,特别涉及一种对开门的防盗紧固门销。
技术介绍
门销是一种从门内侧用来锁门的简单工具,其结构简单,性能可靠,是一种最基本的锁具。但是,对于对开设计的大门,现有技术中,门销基本都是由L形活动销配合销孔锁门,在L形活动销上设置挂板,在另一扇门上设置挂钩,在销入锁孔后,挂板扣入挂钩上,结构简单,但是,结构间隙大,安全性较差,存在被人从门缝中把L形活动销别开的风险,因此,需要设计更安全,又方便操作的门销,以满足使用需求。
技术实现思路
本专利技术要解决的技术问题是克服现有技术的上述不足,提供一种对开门的防盗紧固门销。为了解决上述技术问题,本专利技术采用以下技术方案:一种对开门的防盗紧固门销,包括分别安装在对开门上的门销孔单元、门销板单元;门销孔单元包括基板和垂直安装在基板上的销孔板,销孔板上设有销孔,基板安装在门体上;门销板单元包括板体、销挡、挂销;板体安装在门体上,销挡是垂直安装在板体上的竖板,竖板上设有挂销孔;挂销包括下销臂、中销臂和销杆,下销臂一端通过转轴连接在销挡上,另一端与中销臂一端铰接,中销臂另一端与销杆一端铰接,销杆另一端为自由端,插接在销孔中,挂销通过复位结构与销挡连接。进一步的,所述的复位结构是扭矩弹簧。更进一步的,挂销的下销臂一端通过转轴连接在销挡顶端,扭矩弹簧安装在下销臂与销挡的连接轴上,下销臂以连接轴为旋转轴由扭矩弹簧带动旋转复位。更进一步的,挂销的下销臂一端通过转轴连接在销挡底部,扭矩弹簧安装在下 ...
