Abstract

The invention discloses an adjustable-distance mortise lock body. The adjustable-distance mortise lock body comprises a deadbolt lock case 2, a latch bolt lock case 17, a side panel 1, a deadbolt assembly arranged in the deadbolt lock case 2, a latch bolt assembly arranged in the latch bolt lock case 17, a first top-bottom rod 29, a second top-bottom rod 25 and a latch bolt transmission mechanism used for connecting the deadbolt assembly and the latch bolt assembly. The length of the latch bolt transmission mechanism is adjustable, and therefore the distance between the deadbolt assembly and the latch bolt assembly can be adjusted according to needs.

Description

Technical field [0001] The invention relates to a lock body, in particular to a mortise lock body capable of adjusting the distance between a lock core and a handle. Background technique [0002] At present, since there is no clear regulation on the distance between the lock core and the handle in the anti-theft lock standard, the distance between the lock core and the handle of the mortise lock body used in homes and commercial buildings is different. For lock body manufacturers, it is necessary to design mortise locks of different specifications to meet customer needs. For dealers or door factories, it is necessary to reserve mortise locks of different specifications to meet market demand. [0003] In the existing mortise locks, the transmission from the key wheel to the inclined tongue is generally complex in structure and requires high processing accuracy, which brings a certain degree of production cost control and product quality to the factory Difficulty. Summary of the i...
