Abstract

The utility model relates to a reminder without taking keys for door locks. The utility model is characterized in that an insulating sleeve 8 and a metal conducting body 12 are arranged in a marble hole of a lock body 5, and the upper end of the metal conducting body is provided with a binding post 11 and an insulating pad 9; the binding post 11 is connected with a point of a doorbell circuit A, and the lock body 5 is connected with a point of a doorbell circuit B; the insulating pad 9 is provided with a spring 10 which is matched with an end cover 14. When a key is inserted to the target, the metal conducting body 12 is in contact with a marble 13, the circuits A, B are switched on, and the doorbell sounds in time delay. The utility model has the advantages of artful design, simplicity, practicality and no influence on the original function and security of the lock, the problem in people living is solved, and the domiciliary security is enhanced.

Description

Forget a spoon reminiscences

Technical field

The utility model relates to a kind of safe alarm set of Door and its lock, particularly a kind ofly forgets spoon reminiscences of forgetting that pulls out key.

Background technology

People pay much attention to the home safety problem now, every household mostly is equipped with security door, forgets the phenomenon of pulling out key behind the door but often open when going home, and this causes very serious hidden danger, the one, key is easily taken away by the people, and the 2nd, key is replicated oneself and does not also know.Though the problems referred to above ubiquity does not find to overcome the product of this problem on the market, through extensively retrieval, find relevant documents and materials yet.

Summary of the invention

The purpose of this utility model is exactly a kind of technical scheme of reminding the device that pulls key that has that proposes at the shortcoming that exists in the prior art.

To achieve these goals, the utility model has adopted following technical scheme:

A kind ofly forget a spoon reminiscences, it comprises a tinkling of pieces of jade circuit and a cylinder lock, it is characterized in that being provided with an insulation sleeve 8 and a metallic conductor that is slidingly matched 12 in last pellet shot from a slingshot hole of lock body 5 of cylinder lock, the upper end of metallic conductor 12 is provided with a prap 11 and a felt pad 9, prap 11 connects door tinkling of pieces of jade circuit A point by lead, lock body 5 is coupled to the B point of a tinkling of pieces of jade circuit by lead, end cap 14 on felt pad 9 is provided with a spring 10 and is coupled to lock body 5 cooperates, and metallic conductor 12 matches with pellet shot from a slingshot 13 in the lock core 2.Thus scheme as can be seen, essence of the present utility model is when key is inserted into, lock core marble is formed with metallic conductor contact, makes a tinkling of pieces of jade closing of circuit, door tinkling of pieces of jade work, that is the key that opens the door afterwards do not pull out Men Ling and ringing always, reminds you key is also on door.Better scheme is to add a time-delay relay J in door tinkling of pieces of jade circuit, opens behind the door a period of time (can set as required 3-8 second) at you and rings, to avoid unnecessary sound.

Owing to adopted technique scheme, make the utlity model has be skillfully constructed, simple and practical advantage, do not influence former function of lockset and safety, it has solved a great problem in people's life, has strengthened safety at home.

For describing the utility model in detail, following accompanying drawing provides a most preferred embodiment of the present utility model.

Description of drawings

Fig. 1 is the structure sectional view of the utility model lock body part;

Fig. 2 is a structure principle chart of tinkling of pieces of jade circuit.

The specific embodiment

As shown in Figure 1, be provided with lock core 2 in the lock body 5, be provided with 5 pellet shot from a slingshot holes in the lock body 5, wherein 4 lock spring 4, spring 6 and sealing lead 7 are installed respectively, be provided with an insulation sleeve (available plastic or other material) 8 in last pellet shot from a slingshot hole, be provided with the metallic conductor 12 of a column in the insulation sleeve 8, its upper end is provided with a prap 11, the A point of connecting conducting wire in the door tinkling of pieces of jade circuit, lock body 5 is coupled to B point in the tinkling of pieces of jade circuit by lead.Also be provided with a felt pad 9 on metallic conductor 12, connect a spring 10 on it, the spring other end and end cap 14 link, and 14 of end caps are coupled on the lock body 5.4 lock core marbles in the lock core 2 match with lock spring in the lock body respectively, be that key is when being inserted into, each pellet shot from a slingshot is in concordant unlocking condition, and the circular protrusions of metallic conductor 12 lower ends part contacts with last pellet shot from a slingshot 13, makes 2 closures of AB, connect circuit shown in Figure 2, delay time 3-8 second through time-delay relay J, during this period if pull out key, then metallic conductor 12 separates with the lock core marble lock, circuit is not connected, and Men Ling does not ring; Surpass delay time, contact j closure, door tinkling of pieces of jade D sounds, till you pull out key.Fig. 2 is known door tinkling of pieces of jade circuit, and wherein electric main AC220V between door tinkling of pieces of jade K switch cross-over connection and the contact j, can work alone a tinkling of pieces of jade through transformer and bridge rectifier output direct current DC24V safe voltage.

Claims

1, a kind ofly forgets a spoon reminiscences, it comprises a tinkling of pieces of jade circuit and a cylinder lock, it is characterized in that being provided with an insulation sleeve 8 and a metallic conductor that is slidingly matched 12 in last pellet shot from a slingshot hole of lock body 5 of cylinder lock, the upper end of metallic conductor 12 is provided with a prap 11 and a felt pad 9, prap 11 connects door tinkling of pieces of jade circuit A point by lead, lock body 5 is coupled to the B point of a tinkling of pieces of jade circuit by lead, end cap 14 on felt pad 9 is provided with a spring 10 and is coupled to lock body 5 cooperates, and metallic conductor 12 matches with pellet shot from a slingshot 13 in the lock core 2.

2, according to claim 1ly forget a spoon reminiscences, it is characterized in that being associated with in the tinkling of pieces of jade circuit time-delay relay J.
