Abstract:
A lock (10) capable of adjusting the length of a top and bottom pull rod, comprising two connecting blocks (20) which may move up and down on upper and lower sides of the lock (10) and which are drivingly connected to a lock cylinder; pull hooks (30), pull rods (40) and latch bolts are sequentially formed on sides of the connecting blocks (20) that are far from the lock cylinder; slotted holes (31) are formed on the pull hooks (30) along the moving direction of the connecting blocks (20), and fixing holes (21) are formed on sides of the connecting blocks (20) that are far from the lock cylinder, the slotted holes (31) and the fixing holes (21) being detachably and fixedly connected by means of screws (22). The lock (10) capable of adjusting the length of a top and bottom pull rod solves the technical problem wherein existing top and bottom locks cannot adjust the telescopic distance of upper and lower latch bolts, and cannot be applied to doors having different gap sizes.
