Description

Two-section type linkage lockpin double-leaf door lock

Technical Field

The invention relates to the field of living home and security, in particular to a two-section linkage lockpin two-leaf door lock.

Background

With the rapid development of economy in China, the field of building decoration also enters a high-speed development stage. The lockset becomes an indispensable device, and the security protection requirement of daily life of the house is concerned. Various types and more advanced door locks are available on the market, and various single-page door locks are diversified, such as a ball lock, a handle lock, an electronic lock, a fingerprint lock, a remote control lock, a card lock and the like.

However, the application of the double-leaf door is still quite common, and especially the self-building in rural areas and the public buildings (such as hospitals, office buildings and the like) in cities are quite widely applied.

The common double-leaf door lock in life mainly has the following forms: (1) the surface-mounted transverse latch is combined with the surface lock. The open lock is troublesome to operate, can be unlocked only by using two hands, has poor anti-theft performance, is easy to lose, and is inconvenient for the old and children to use. (2) The bolt is combined with the latch lock. One side door leaf is fixed by an upper bolt and a lower bolt, and the other side is provided with a latch lock. However, when the upper plug pin is too high, a child cannot reach the upper plug pin, and when the lower plug pin is too low, the old man is difficult to bend over, the operation is inconvenient, and if the plug pin is forgotten to be inserted, the gate pole is easy to push away, so that the safety is not high and the reliability is low. (3) Two-leaf door locks are common. The spring lock and the bolt are hidden in the aluminum door sheet, but the bolt hidden in the aluminum door sheet can be locked only by additionally pushing and pulling the bolt switch, and the bolt switch can be easily pushed to open if the bolt switch is forgotten to be pulled, so that the safety and the stability are not high.
