Abstract

The invention relates to an elastic telescopic type external door lock with multiple opening modes. The elastic telescopic type external door lock with the multiple opening modes comprises a front lock cylinder, a disengagement and engagement assembly, a lock liner plate and a rear lock cylinder, wherein the lock liner plate is fixed in a lock case, the disengagement and engagement assembly is limited to the lock liner plate, and the lock case is covered with a cover plate; the front lock cylinder is limited to the cover plate, the rear lock cylinder is limited to the lock case, the front lock cylinder is fixedly connected with a shifting fork through an opening rod, and the rear lock cylinder is fixed to a rear lock cylinder bush which is fixedly connected with the shifting fork. The position of a key of the front lock cylinder is sleeved with a lock cylinder housing in which a lock cylinder cover is additionally arranged, and a battery box cover is fixed to the lock case and located on the rear lock cylinder. A lock body panel is fixed to one side of the lock case and arranged on a spring bolt of a spring bolt plate in the disengagement and engagement assembly in a sleeving mode, and a door frame distributed corresponding to the lock body panel is provided with opposite door paste boxes. The elastic telescopic type external door lock has the advantages of being novel in structure and reliable in performance and taking safety and convenience both into consideration.

Description

technical field [0001] The invention belongs to the technical field of door locks, in particular to an elastic telescopic exterior door lock with multiple opening modes. Background technique [0002] At present, there are many types of lock bodies, but the more common lock bodies are electronically controlled lock bodies and mechanical lock bodies. Due to the insufficient design of the lock bodies, some lock bodies cannot be electrically controlled. The control type and the mechanical type are used together, predicting the consequences that may be eliminated in the future, and cannot keep up with the trend of the times; the lock body of the exterior door lock is relatively rare, resulting in a relatively vacant market. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide an elastic telescopic exterior door lock with novel structure, reliable performance, safety and convenience, which has multip...
