Abstract
The invention provides a key insertion alarm lock which can give the alarm when a key is inserted in the key insertion alarm lock and stays in a lock hole, thereby achieving the function of preventing a thief or reminding a user to pull out the key. A lock hole fixed contact is arranged in the end of the lock hole; a leaf spring is arranged outside the lock hole fixed contact; the leaf spring is provided with a lock hole movable contact; a cylinder bottom fixed contact is arranged at the cylinder bottom of a lock cylinder and located on the center axis of the lock cylinder; a lock cylinder center axis contact is arranged on the cylinder bottom fixed contact and is always in contact with the cylinder bottom fixed contact; the lock cylinder center axis contact is connected with the lock hole fixed contact through a conducting wire; a round contact, of which the center is located on the center axis of the lock cylinder, is arranged at the cylinder bottom of the lock cylinder; a lock cylinder edge contact is arranged on the round contact and is always in contact with the round contact; the lock cylinder edge contact is connected with the leaf spring of the lock hole fixed contact; the cylinder bottom fixed contact is connected with one conducting wire of a sounder; the other conducting wire of the sounder is connected with a power supply; and the other conducting wire of the power supply is connected with the round contact. When the key is inserted in the lock hole, the lock hole movable contact is contacted with the lock hole fixed contact, and the sounder gives the alarm.
Description
Technical field
The present invention relates to a kind of key and insert alarming lock, especially when insertion key and key leave in keyhole, can chimes of doom be sent, play antitheft or remind the effect transfering to key.
Background technology
Traditional lockset leaves in keyhole when insertion key and key, can not send chimes of doom, can not play antitheft or remind the effect transfering to key.
Summary of the invention
Leave in keyhole in order to overcome traditional lockset when inserting key and key, chimes of doom can not be sent, can not play antitheft or remind the deficiency of effect transfering to key, the invention provides a kind of key and insert alarming lock, especially when insertion key and key leave in keyhole, can chimes of doom be sent, play antitheft or remind the effect transfering to key.
The technical solution adopted for the present invention to solve the technical problems is: key inserts alarming lock, in keyhole, end place is provided with keyhole fixed contact, 1 is provided with spring leaf outward, spring leaf is provided with keyhole armature contact, at the bottom of lock core tube upper lock core cental axial position to be provided with tin at the bottom of fixed contact, cylinder end fixed contact is provided with contiguous lock core central axis contact all the time, lock core central axis contact is connected with keyhole fixed contact wire, the circular contact of the center of circle on lock core central axis is provided with at the bottom of lock core tube, circular contact is provided with contact, contiguous lock core limit all the time, contact, lock core limit is connected with the spring leaf wire of keyhole armature contact, cylinder end fixed contact is connected to acoustical generator wire, another wire of acoustical generator is connected to power supply, another wire of power supply is connected to circular contact.Key inserts keyhole, and the spring leaf in keyhole to more depths, is made the keyhole armature contact on spring leaf contact with keyhole fixed contact by key bending, sounder circuit connection, and acoustical generator just sounds the alarm; Key rotation lock core, fixed contact at the bottom of lock core central axis contact and cylinder all can not be separated from because lock core rotates on lock core central axis, the center of circle of same circular contact is on lock core central axis, circular contact and contact, lock core limit also can not be separated from because lock core rotates, have rotated lock core like this, key circuit in keyhole can not disconnect, acoustical generator also can sound the alarm, only has dial-out key, spring leaf in keyhole resets, separately, circuit disconnects, and alarm song could be closed for keyhole armature contact and keyhole fixed contact.
The invention has the beneficial effects as follows, key inserts alarming lock, when insertion key and key leave in keyhole, can send chimes of doom, plays antitheft or reminds the effect transfering to key.
