Abstract

The utility model discloses a double core built-in lock and key thereof, belonging to the technical field of the architectural lockset. The lock core of the existing various lockset is single core, the safety and the security are bad. The utility model adopts double rotating core structural core body, which is composed of rotating heart core 1, a rotating middle core 2, a core body 3; the same key is used to align a retaining pin twice, and the lock can be unlocked and locked, the safety and the security are improved.

Description

Double parts mortise lock and its key

Twin-core built-in lock core and key belong to lock technology field in the building trade.

At present the various built-in lock cores that use are the monolock core, when open and close locks, key insert the lockhole one-time positioning again screw key just can open lock or lock, so security reliability and safety in the use are poor.

The purpose of the utility model design is to be to improve lockset reliability and safety, makes the structure design of lockset more advanced, reasonable, compact, easy to use.

The structure design of twin-core built-in lock core and key: it is two boss of 3 millimeters that the position that key contacts with the lock core end face is designed to fore-and-aft distance; Lock core by rotate heart core, rotate SMIS, core body is formed, spring latch system, the lock core card gland of six pin-and-holes of orthogonal two groups of every rows, turn round sheet and form.The purpose that is designed to two rotating cores is: carrying out aiming at for twice latch with key could lock in open and close, reaches purpose reliable, insurance.The relative position of each parts and planform are: rotate heart core and be contained in the rotation SMIS, rotating SMIS is loaded in the core body again, the orthogonal latch of two rows, spring system are arranged on the center of rotation, six pin-and-holes of every row respectively have a row and rotate the corresponding lock pin aperture of SMIS two row's pin-and-holes and rotate on heart core and the core body.Spring, latch will rotate heart core, rotation SMIS, core body through combine and assemble and join together.Be processed with the location pit of two symmetries on the center of rotation outer face, its degree of depth is respectively 6 millimeters and 3 millimeters, is to be used for normal key when open and close are locked.Card make rotate heart core can only be in rotating SMIS rotation and can not do axially-movable, gland makes and rotates SMIS and can only rotate in core body and can not therefrom pull out, and can also drive simultaneously to turn round sheet and rotate and reach the purpose that open and close are locked with rotating SMIS.

Description of drawings:

Fig. 1: twin-core built-in lock core front view;

Fig. 2: A-A sectional drawing;

Fig. 3: B-B sectional drawing;

Fig. 4: key front view;

Double parts mortise lock is by forming with lower member: 1 rotates heart core; 2 rotate SMIS; 3 core bodys; 4 rotate SMIS I latch; 5 rotate heart core latch; 6 rotate SMIS II latch; 7 core body latch; 8 springs; 9 cards; 10 glands; 11 turn round sheet; 12 keys.

The characteristics of Double parts mortise lock and key:

1, adopt two rotating core structures, latch increases to two rows by a row of routine lock, and four or five of every rows that pin-and-hole is locked by routine increase to six of every rows, must aim at latch after key inserts for twice and could open and close lock, and has improved reliability and safety;

2, two rotating cores are contained in the same core body, and compact conformation is simple to operate;

3, if substitute the lock core of former single core built-in lock with this lock core, must not change lock body, need only take off former monolock core with get final product of this generation, installation is easy, and interchangeability is strong.

4, the structure design of key also makes it in use have reliability and safety.

Most preferred embodiment:

Open, when shutting, key 12 is inserted in the keyhole that rotates heart core 1, and make boss a with the outer face contact of rotating SMIS 2, the outer face of rotating heart core latch 5 this moment overlaps with the outer garden line that rotates heart core 1, key 12 can make rotates heart core 1 rotation in rotating SMIS 2, with key 12 left-handed 90 more inwards on time, the boss a of key 12 and b fall into the c that rotates SMIS respectively, in the d groove, at this moment, the outer face of rotating SMIS II latch 6 overlaps with the outer garden line that rotates SMIS 2, key 12 makes and rotates heart core 1 and rotate SMIS 2 rotation in core body 3 simultaneously again, rotate SMIS 2 and drive glands 10 rotations and make and turn round sheet 11 and also rotate, reached and opened, the purpose that shuts.

Claims

1, twin-core built-in lock core is made up of rotation heart core 1, rotation SMIS 2, core body 3, it is characterized in that: rotate heart core 1, rotation SMIS 2 and core body 3 and be the coaxial one that radially is set in successively.

2, by the described twin-core built-in lock of claim 1 core, it is characterized in that: rotating has two rows, 6 lock pin aperture of vertical every row mutually on the SMIS 2, rotate 6 lock pin aperture of an every row of row are respectively arranged on heart core 1 and the core body 3, to rotate SMIS 2 and rotate rotation SMIS I latch 4 that heart core 1 joins together, rotate heart core latch 5 and spring 8 is arranged in order in lock pin aperture, in lock pin aperture, be arranged in order rotating rotation SMIS II latch 6, core body latch 7 and the spring 8 that SMIS 2 and core body 3 join together.

3, by the described twin-core built-in lock of claim 1 core, its feature also is: the location pit c and the d that rotate the degree of depth that two symmetries are arranged on the outer face of SMIS 2 and be 6 millimeters and 3 millimeters.

4, twin-core built-in lock core and key, it is characterized in that having on the key 12 fore-and-aft distance is 3 millimeters boss a and b.
