Mortise lock body with escaping function

Abstract

The invention relates to a mortise lock body with an escaping function. The mortise lock body with the escaping function is characterized in that a shifting wheel assembly which is synchronously in driving connection with an inclined tongue assembly and a square tongue assembly is arranged in a lock housing, wherein the shifting wheel assembly is provided with a safety tongue shifting part; an escaping shifting wheel and a safety tongue shifting wheel are arranged in the lock housing; the safety tongue shifting part is in driving connection with the escaping shifting wheel when the inclined tongue assembly is driven by the shifting wheel assembly to contract to an opening state; the safety tongue shifting wheel is in driving connection with a safety tongue assembly on the lock housing, andmoreover, the escaping shifting wheel is in transmission connection with the safety tongue shifting wheel through a connecting rod assembly, and the safety tongue assembly is driven by the safety tongue shifting wheel to unlock and open. Therefore, the inclined tongue assembly, the square tongue assembly and the safety tongue assembly can be synchronously opened by operating a lever handle in onetime. The mortise lock body with the escaping function has the escaping function, and is simple, convenient and quick to operate; and the defect problem of independently opening the safety tongue assembly of an existing lock body can be solved.

Description

technical field [0001] The invention belongs to the technical field of locks, in particular to a mortice lock body with an escape function. Background technique [0002] At present, the lock bodies (such as: handle locks) on the market are all equipped with a bolt assembly, a square bolt assembly and a safety tongue assembly, wherein the bolt assembly and the square bolt assembly are controlled to open by the bolt dial, and the safety tongue assembly passes through the safety bolt. The tongue dial controls the opening, and the oblique tongue dial and safety tongue dial are operated and controlled separately. They do not have the escape function, and the operation is cumbersome and time-consuming, which greatly reduces the chance of escape. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a belt escape system that can open the oblique tongue assembly, the square tongue assembly and the safety ...
