High-bearing-capacity door lock
The invention discloses a high-bearing-capacity door lock which comprises a plastic lock shell and a spring bolt stretching out and drawing back inside the plastic lock shell. A reinforced lining plate is mounted between the spring bolt and the plastic lock shell. One end of the reinforced lining plate is fixed to the plastic shell, and the other end of the reinforced lining plate is bent towards one side of the spring bolt to form a bent part. A shuttling hole for the spring bolt to stretch out and draw back is formed in the bent part, and the two ends of the bent part are both fixed to the side face of the plastic lock shell. When a door locked through the door lock is subjected to large impact force, the reinforced lining plate blocks the impact of the spring bolt on the plastic lock shell, the plastic lock shell is better protected, and the plastic lock shell is prevented from being damaged by the impact force. The lock shell is made of a plastic material instead of a traditional metal material, so that the load bearing of the door lock can be ensured, the safety performance of the door lock is improved, the manufacturing cost of the lock shell can also be reduced, the lock shell is convenient to produce and manufacture, and the weight of the door lock is reduced.
本发明公开了一种高承载的门锁，包括塑料锁壳和伸缩于塑料锁壳内外的锁舌；所述锁舌和塑料锁壳之间安装有加固内衬板；所述加固内衬板的一端固定于塑料壳体上，另一端向着锁舌一侧折弯形成折弯部；所述折弯部上开设有供锁舌伸缩的穿梭孔，且折弯部的两端均固定于塑料锁壳的侧面；当通过该门锁锁住的门受到较大冲击力时，所述加固内衬板挡住锁舌对塑料锁壳的冲击，更好的保护了塑料锁壳，避免塑料锁壳受到冲击力的破坏；使得锁壳采用塑料材质替代传统的金属材质锁壳，即能保证门锁的承重，提高门锁的安全性能，也能降低锁壳的制造成本，便于锁壳的生产制造，同时减轻了门锁的重量。
