Abstract

The utility model relates to a trick lock, which can be arranged on the sliding door of a warehouse, and is especially suitable for the warehouse door of a goods train. A slideway dark chamber which can be used for replacing a key open-close device is arranged in the hard casing of a lock chamber. The end head of the lock core of the key open-close device is provided with a groove which is inosculated with the pinion of a locking device. The pinion which can drive a big gear wheel to rotate anticlockwise can be driven by clockwise rotating the lock core. A locking process can be completed by that a lock clamp lever system which is connected with the big gear wheel can send a weight-loaded lock clamp to the zigzag locking groove of the lock tongue of an inserting lock chamber. The pinion, the big gear wheel and the lever driving system can cause the lock clamp to leave from the lock tongue locking groove by rotating the lock core anticlockwise, and the trick lock can be opened.

Description

The Mortise lock built-in lock

The utility model relates to a kind of Mortise lock built-in lock of mechanical engineering field, is particularly useful for the goods train door and uses.

At present; the security door lock protecting cipher device patented product that Intellectual Property Right Bureau of the RPC announces; be that the built-in lock core that will expose in the open all seals; adopt pin mode; open according to the feel check mark; have the effect of present all kinds of built-in locks all being played the protection lock core, do not need to reequip the door institute of existing security door.Known built-in lock structure is to be made of the pintle hook lock that the key that is fixed in the lock housing closes outside opening device, drive link, dead bolt and the lock housing.The dead bolt of known built-in lock is for the ease of entering pintle hook lock smoothly with dead bolt at closing time, its head is half wedge shape, hemispherical or rectangle etc., generally be used for security door, safety cabinet and furniture, known built-in lock can not be used for sliding door, because its pintle hook lock is to the axially-movable latch-up-free effect of dead bolt.

The purpose of this utility model provides a kind of Mortise lock built-in lock, and it is strong that it not only has a theftproof performance, and sturdy and durable, use and change conveniently.

The purpose of this utility model is achieved in that the upper right corner is provided with the darkroom that replaceable key closes opening device in the hard shell of lock chamber, the below in darkroom is provided with the slideway that replaceable key closes opening device, put in that cassette cover switch hole one is disclosed and outside one draw and open cassette cover with bottle opener, key is closed opening device to be advanced downwards along slideway, the groove and the pinion in the locking device that key is closed open on the lock core termination in the opening device coincide, shut the built-in lock lid, inject lock core clockwise direction rotational lock core with key, lock core drives pinion driving gear wheel and rotates counterclockwise, lever one end that the ingot-shaped connecting rod that is connected with gear wheel promotes the connection pintle hook lock moves upward, to the lever other end that connects pintle hook lock is moved downward, the Weight type pintle hook lock of suspended levers termination is sent in the dead bolt zigzag lock slots that injects the lock chamber finished locking process.If inject lock core rotational lock core counterclockwise with key, just in time opposite with said process, the Weight type pintle hook lock leaves dead bolt zigzag lock slots under the effect of gear and lever system, and after dead bolt can be pulled out the lock chamber with sliding door, built-in lock promptly was opened.Dead bolt is that the zigzag lock slots that digs on the side by rectangular steel plates is made, and it is inserted or pulled out by lock lower left, chamber lock-tongue port.

Owing to adopt such scheme, can make sliding door that built-in lock is installed, not only the built-in lock core that will expose in the open all is enclosed in the hard shell, and can change key easily and close opening device, has strengthened pick-proof, anti-drilling, anti-blocking and confidentiality.

Below in conjunction with drawings and Examples the utility model is further specified.
