Abstract

The utility model discloses a lock with a code and a key. The utility model is characterized in that a key core set is arranged beside a lock tongue 1, a collision pull rod (16) is spanned between a bolt moving block 3 and a ratchet card collision 12, a ratchet card 13 is engaged with a tooth of one end of a cam 15, and a code press key is covered on a press rod 9. The utility model can realize unlocking by the code, or by the key, or by the combination of the code and the key. The utility model has the advantages of convenient use and safe use.

Description

The cipher key two-bolt lock

The utility model relates to a kind of cipher key two-bolt lock, belongs to the coded lock technology field.

Propose and granted " the not reproducible ink recorder tool coded lock of pressing " (patent No. 91209779.5) and " but the not reproducible key cipher lock of escape " (patent No. 93221948.9) by me, can only lean on password unlocking, can not switch to available key or password unlocking or need key and password unlocking simultaneously according to different situations.

The purpose of this utility model is to provide a kind of cipher key two-bolt lock, to overcome above-mentioned deficiency.

The technical solution of the utility model is:

It is other that spoon core group is positioned at dead bolt 1, the spoon core driving lever 4 other latches 5 that are provided with in spoon core group, bolt moves the other button 6 of locking that is provided with of piece 3, collision pull bar 16 is set up in bolt and moves between piece 3 and the ratchet card collision 12, ratchet card 13 meshes with the tooth of double wedge axle 7 overhead cams 15 1 ends, and password key 10 buttons cover on the depression bar 9.

The bearing 19 of spoon core group is fixed on the lock housing 2, bolt moves piece 3 and is connected on the bearing 19 by pin, and bolt moves piece 3 and 19 of bearings and is provided with one and moves spring 18, and mobile spring 18 1 ends are fixed in bearing 19, one end is fixed in bolt and moves piece 3, and the spoon core 17 of band spoon core driving lever 4 is fixed on the bearing 19.

Cam 15 is made as one with double wedge axle 7, and an end of cam 15 is provided with tooth, and its teeth directional is consistent with the teeth directional of convex gear 8.

Ratchet card 13 is connected as a single entity with ratchet card collision 12, be loaded on the ratchet deck 22, spring 23 is loaded on the cross bar 27 of ratchet card collision 12, collision pull bar 16 1 ends are fixed in the ratchet card collision 12, one end jag is two bars, one bar bends in bolt and moves between piece 3 and the spoon core driving lever 4, and a bar places in the pilot hole of double wedge axle bed 14.The indoor bar 21 that undoes the lock is a fulcrum with ratchet deck 22, and an end is outside lock housing, and an end is pressed in the ratchet card collision 12.

The utility model can realize easily or with password unlocking open the lock with the key or cipher key in conjunction with unblanking, promptly made things convenient for use, safe and reliable again.

Be further described below below in conjunction with accompanying drawing:

Press the button 6 of locking, bolt moves piece 3 and rotates under the drive of the button 6 of locking and replace dead bolt 1, and lock is pinned.

The pressure of pushing password button 10 is by 24, and pressure makes depression bar 9 press down convex gear 8 by 24, thereby drives 7 rotations of double wedge axle.Unclamp pressure by 24,, press to reset rapidly by 24 owing to be with spring 26 on the seam bolt 25.Double wedge axle 7 is because the tooth of cam 15 1 ends and ratchet card 13 mesh, and double wedge axle 7 can be fixed in the position that rotates to.Press each password button 10 in succession according to proper password, the cam 15 on the double wedge axle 7 is depressed ratchet card collision 12, and ratchet card collision 12 drives collision pull bars 16 and moves down, and the bending end of collision pull bar 16 drives bolt and moves piece 3 rotations and leave and replace dead bolt 1, and can open lock this moment.Because this moment, ratchet card 13 left engagement with the tooth of cam 15 1 ends, double wedge axle 7 resets under spring 20 effects, ratchet card 13 also resets under spring 23 effects, if push the wrong the password button, depression bar 9 can not press down convex gear 8 again, double wedge axle 7 deadlocks can not be rotated in this position again, can only with key be rotated counterclockwise lock core shift lever 4 collision pull bar 16 depressed outdoor this moment, collision pull bar 16 drives ratchet card 13 and ratchet card collision 12 moves down, tooth on ratchet card 13 and the cam 15 leaves engagement, and double wedge axle 7 resets rapidly under the drive of spring 20.Lock can be opened according to proper password again.

When opening the lock with the key, key band moving spoon core driving lever 4 is rotated counterclockwise, and spoon core driving lever 4 drives collision pull bars 16 and moves down, and the bending end of collision pull bar 16 makes bolt move piece 3 again and is rotated counterclockwise to leave and replaces dead bolt 1, and can open lock this moment.If press latch 5, latch 5 blocks spoon anglec of rotation of core driving lever 4, and can only make double wedge axle 7 reset with key this moment, and lock is opened.

If the people indoor, then only need upwards spur the indoor bar 21 that undoes the lock, the indoor bar 21 that undoes the lock is a fulcrum with ratchet deck 22, pressing ratchet card 13 and ratchet card collision 12 moves down, drive collision pull bar 16 and move down, be rotated counterclockwise to leave and replace dead bolt 1 thereby make bolt move piece 3, can open lock this moment.
