Embodiment Construction

[0025] Such as figure 1 — Figure 5 As shown, the door lock with rack and pinion bolt of the present invention consists of a main housing (A), an auxiliary housing (B), a support plate (1), a bearing (2), a riveting shaft (3), and a driving gear (4 ), rotating shaft (5), screw (6), driven rack (7), bolt socket (8), lockset (9), handle (10), sub-housing outline (11), bolt baffle ( 12), the plane of the rotating shaft (13) and the lock tongue (14) are combined; the main and auxiliary housings and the lock are directly embedded on the door panel, and the lock cylinder of the lock is driven by the key to turn the unlocking bolt to control the expansion and contraction of the lock tongue. The locking and unlocking of the door lock is controlled by the telescopic locking bolt and the slot of the driven rack; the handle drives the rotating shaft to control the rotation of the driving gear, and the door is opened or closed through the meshing of the rack and pinion; the feature is th...

Abstract

The invention discloses a gate lock with a gear rack bolt. The gate lock comprises a main casing, a bearing, a riveting nut, a driving gear, a rotating shaft, a driven gear, an auxiliary casing, an externally installed lock and a handle. The main casing and the auxiliary casing and the externally installed lock (externally installed locks produced by various manufacturers can be matched) are directly embedded on a door plate, a lock cylinder of the externally installed lock rotates an unlocking bolt by means of driving of a key, and extension and contraction of a spring bolt can be controlled to be matched with a clamping groove of the driven rack to control locking and unlocking of the gate lock. The handle drives the rotating shaft to control the driving gear to rotate, and unlocking or locking can be performed through meshing of a gear and a rack. The danger that the gate lock can be unlocked by tools of pipe wrenches and the like can be effectively avoided, the anti-theft effect of the gate lock is ensured, and safety is improved.

Description

technical field [0001] The invention specifically relates to a door lock with rack and pinion bolt. Background technique [0002] The gate lock is the lock equipped on the main door leading to the outside of the whole building (excluding indoor door locks). Due to the special position of the gate lock, it is usually extremely strong. Existing door locks are of a great variety, each with its own characteristics, and the requirements for door locks are different in various occasions. Ordinary families generally use anti-theft door locks, which are safe and relatively cheap. As a security product, door locks must be safe and stable. Safety can be measured from two aspects: one is resistance to vandalism, pranks and deliberate violent damage such as prying and drilling. In this regard, the mechanical strength of mechanical locks and electronic door locks can generally meet the requirements. Among all kinds of locks, only the rf card electronic locks are fully enclosed structu...
