Anti-prying and anti-smashing door locking device
The invention provides an anti-prying and anti-smashing door locking device. The anti-prying and anti-smashing door locking device is composed of a first locking arm (10), a second locking arm (20), apadlock (30) and a protective cover (40). The protective cover (40) is a box-shaped piece with an opening (47) formed at the bottom. Symmetrical through notches (46) are formed in a front plate (41)and a rear plate (42) of the protective cover (40). The first locking arm (10) and the second locking arm (20) with up and down notches in the middles are fixed to a door leaf and a door frame in parallel in a flush manner, the first lock arm (10) and the second lock arm (20) penetrate through the through notches (46) of the protective cover (40) and an annular lock beam (31) of the padlock (30),and the padlock (30) is limited between the upper notches and the lower notches of the first locking arm (10) and the second locking arm and meanwhile is limited in the protective cover (40). The upper part of the padlock (30) is provided with the annular lock beam (31), and the lower part of the padlock (30) is provided with a key hole (32); and locking and unlocking can be completed by operatingthe padlock (30) at a bottom opening (47) of the protective cover (40).
本发明提供了一种防撬防砸的锁门装置，由锁臂甲（10）、锁臂乙（20）、挂锁（30）、防护罩（40）构成。防护罩（40）为底部设有开口（47）的盒状件，其前板（41）、后板（42）上设有对称的贯穿槽口（46）；中部设有上下缺口的锁臂甲（10）和锁臂乙（20）并列平齐地固定在门扇和门框上，一并穿过防护罩（40）的贯穿槽口（46）和挂锁（30）的环状锁梁（31），挂锁（30）被限制在锁臂甲(10)和锁臂乙（20）的上下缺口之间，同时也被限制在防护罩(40)内部；挂锁（30）上部设有环状锁梁（31），下部设有钥匙孔（32）；在防护罩（40）的底部开口（47）处操作挂锁（30）即可完成闭锁和开锁。
