What is a lock tongue? Why do you need to look at the locking tongue when choosing a smart lock? In fact, the locking tongue also has an important influence on the performance of smart locks. The following small series of China smart lock network will take you to unlock the tongue and inspect the performance of smart lock in all directions.
Locking tongue material
As an important load-bearing component, the lock tongue has strict requirements on the firmness of the material. Our common locking tongue materials are zinc alloy, stainless steel and so on. Generally speaking, stainless steel shows better strength than zinc alloy material, and it is not easy to deform when impacted. In addition, stainless steel also has the characteristics of corrosion resistance and high temperature resistance.
The main locking tongue of Dingji intelligent lock is made of stainless steel and solid locking tongue. This makes the bolt of Dingji intelligent lock have the characteristics of high strength, and the main bolt can bear the impact of high pressure in both axial and lateral directions.
Oblique tongue and square tongue
The inclined tongue has a spring component, and criminals can easily push it back through a card, thus achieving the purpose of unlocking, and the safety performance is worrying. If you only rely on the oblique tongue for anti-theft without anti-locking, the card unlocking and burglary you have heard may be staged in real life.
Compared with the oblique tongue, the square tongue has no spring parts and will not retract due to external forces such as card extrusion. The locking tongue used in Dingji intelligent lock is square tongue, which is convenient to use combined with automatic locking function.
The inclined tongue used in Dingji intelligent lock is a two-way flip lock tongue, and the two sides are designed at right angles to prevent the card from opening the door. Because the two-way flip lock tongue has rebound function, it can lock the door against wind.
Single locking bolt and multiple locking bolts
The number of locking bolts may be different with different lock bodies, including single locking bolt and multiple locking bolts. Compared with a single lock tongue, when multiple lock tongues are violently opened, prying one lock tongue will not cause fatal blow to the anti-theft function. In particular, the main locking tongue of Dingji intelligent lock TOP300R and other models has anti-sawing and anti-collision functions, effectively preventing violent unlocking.
The main lock tongue of Dingji intelligent lock TOP300Q and other models has anti-collision and anti-prying functions, which is more durable. In addition, smart locks such as TOP300Q have safety tongues in addition to oblique tongues and main locking tongues, which will pop up when locked indoors. At this time, it can only be unlocked from indoors, and the door cannot be opened outdoors.
Locking tongue is also an important part of lock body, and inferior locking tongue will have a great impact on the performance of lock body.
