Abstract

The utility model relates to a portable key cylinder lock, which is composed of a lock casing, a lock core, a lock latch and a key. The inner part of the lock core is provided with cylinders and a spring, the spring and upper cylinders are arranged in a pull-push rod or a twisting rod, and a key hole is arranged at the outer part of the movable lock core. After the key is inserted into the key hole, the lower part of multiple rows of upper cylinders is arranged on the same plane, and is parallel with the outer wall of the pull-push rod or the twisting rod. The pull-push rod or the twisting rod can be moved forwards and backwards or can be moved in rotation, and the lock latch is opened but the key can not be rotated. The key does not support the twisting force, etc. The utility model can be made into a thin and light lock, and can be made of materials, such as the nylon, the plastic, the stainless steel thin piece, etc.

Description

Cylinder lock operated by light key

The utility model relates to cylinder lock.

Existing cylinder lock after key inserts lock core, reverses certain angle again, and lock bolt is opened.The opening ways of such cylinder lock because key need bear bigger torsional moment, so the material of key must select mechanical strength good, structurally has enough wide and thick.The key heaviness that so just must seem, have many key chain of this heaviness is hung over together on one's body, not only weight is big, but also can pollution clothes.

The purpose of this utility model be design a kind of in lock core, install special-purpose pulling-pushing rod or torque rod, key only plays guiding and the thin light key pins lock of light weight wall.

The technical design scheme of light key pins lock of the present utility model is: be made up of lock housing, lock core, lock bolt and key, pellet shot from a slingshot and spring are installed in lock core body, pellet shot from a slingshot and spring are installed in pulling-pushing rod or the torque rod on it, and keyhole is in the outside of pellet shot from a slingshot flexible lock core.Be pulling-pushing rod or the torque rod part at the pellet shot from a slingshot flexible lock core, after pulling-pushing rod or torque rod activity, lock bolt breaks away from pulling-pushing rod or torque rod, and lock is opened.

The utility model discloses a kind of light key pins lock, its lock core is movable to rely on a pulling-pushing rod or torque rod, and key only works the flat effect of leading to pellet shot from a slingshot.Compared with the prior art this lock, and its key can make thin and light, can adopt nylon, plastics, stainless steel thin slice etc. to make.The little light weight of key volume, easy to carry, reduce and stain clothing etc.

Fig. 1 installs the pulling-pushing rod schematic diagram in the light key pins lock pin of the utility model;

Fig. 2 installs the torque rod schematic diagram in the light key pins lock pin of the utility model;

Fig. 3 does not insert key for the light key pins of the utility model lock, and torque rod is by the pellet shot from a slingshot schematic diagram of box-uping;

Fig. 4 is the light key pins lock pin of the utility model lateral view (shown in pulling-pushing rod);

Fig. 5 is the light key pins lock pin of the utility model lateral view (shown in torque rod).

Below in conjunction with Fig. 1-Fig. 5 embodiment of the present utility model is done detailed explanation.

1, lock core body; 2, spring; 3, go up pellet shot from a slingshot; 4, following pellet shot from a slingshot; 5, key; 6, pulling-pushing rod; 7, torque rod; 8, keyhole.

The utility model provides a kind of light key pins lock, and the lock core that relates generally to existing cylinder lock improves design, and existing common spring lock housing needn't change, and it is thin, less or pollution-free to make key change light weight, body into, is easy to carry.By lock core body 1, pulling-pushing rod 6 or torque rod 7 are installed in the lock core body, spring 2 and last pellet shot from a slingshot 3 are positioned in pulling-pushing rod or the torque rod, and following pellet shot from a slingshot 4 is positioned in the keyhole 8.After key 5 inserts keyholes 8, the contact surface of several row of upper and lower pellet shot from a slingshot all at grade, pulling-pushing rod 6 or torque rod 7 can be movable; After key 5 was transferred to keyhole 8, pulling-pushing rod 6 or torque rod 7 are box-uped by last pellet shot from a slingshot 3, and be stiff, and its key 5 inserts keyhole 8, and pulling-pushing rod 6 seesaws, if torque rod 7 is installed, then torque rod rotates.Pulling-pushing rod or torque rod match with lock bolt, once motion lock be opened, key only rises last pellet shot from a slingshot and leads flatly, do not bear effects such as torsion.

Claims

1, light key pins lock, formed by lock housing, lock core, lock bolt and key, pellet shot from a slingshot and spring are installed in lock core body, it is characterized in that spring (2) and last pellet shot from a slingshot (3) are installed in pulling-pushing rod (6) or the torque rod (7), and keyhole (8) are in the outside of flexible lock core.

2, light key pins lock as claimed in claim 1 is characterized in that key (5) is made by nylon or plastics or stainless steel thin slice.
