Description

A kind of theftproof lock of energy delayed alarm

The utility model relates to the theftproof lock that automobile, motorcycle, security door etc. use.

At present, the lock of uses such as automobile, motorcycle, security door is generally built-in lock, the common drawback of these locks, and the one, the thief can insert lockhole with other object such as the key of same model lockset or cleek and sound out lock is opened, thereby carries out stealthy activity; The 2nd, it is careless and key is forgotten locking sometimes as the owner of automobile, motorcycle, security door, also can offer an opportunity to the thief, thereby gives the individual, and public property is brought loss, and also influence society is stable.Both of these case all is to be difficult for being found by the people and taking place under the situation of any damage does not appear in lockset in appearance.

The purpose of this utility model is exactly supporting with lockset and do not match key or other object inserts lockhole, if lock can not be opened the theftproof lock that chimes of doom will take place within a certain period of time.

In order to achieve the above object, feature of the present utility model is that lock body (6) is provided with the delayed alarm device, and it comprises delayed alarm circuit, junction block (1) and horizontal switch (4); Junction block is provided with the inner chamber (1-2) that communicates with lockhole (5-1), and this inner chamber has and the extraneous two passes (1-1) that communicates; Laterally switch (4) is located in the inner chamber and lockhole (8-1) of junction block, its upper end links for circular arc and by rotating shaft (10) and junction block, also form eccentric the contact with an end of compression spring (2), the other end of compression spring then contacts with the internal chamber wall of junction block (1); Two connector lug a, b in the delayed alarm circuit can be electric conductor by the two passes on the junction block (1-1) the horizontal switch (4) that contacts with horizontal switch (4), and junction block (1) is an isolator.

Lock body (6) is provided with the delayed alarm device, it comprise delayed alarm circuit, junction block close by this passage can with two connector lugs in the electronic alarm circuit, a, b contact simultaneously or do not contact; Laterally switch (4) is located in the inner chamber and lockhole of junction block, it is installed on the junction block (1) by rotating shaft (10) for an end of circular arc, and form eccentric the contact with the lower end of compression spring (2), the upper end of compression spring then is installed on the junction block, and compression spring is between the two passes on rotating shaft and the junction block.Laterally switch is an electric conductor, and junction block is an isolator.

When key inserts in the lockhole, horizontal switch can be promoted forward and rotates along clockwise direction around the shaft, laterally switch can be simultaneously be located at the junction block two passes in connector lug a, b contact, thereby make the electronic delay warning circuit form the closed-loop path, if key and open lock not in 3 seconds will be sent chimes of doom; If clockwise rotate key, laterally switch is because the effect of compression spring falls into the groove on the lock core, thus the cut-out circuit.

By Fig. 3, Fig. 4 as can be known, this lockset comprises lock body (6), lock core (5), lock (9), spring (8), lead (7), electronic alarm device is set on lock body, it comprises the electronic delay warning circuit, by line seat and horizontal switch, be packed on the lock body by bolt (3) by the line seat, junction block is provided with inner chamber (1-1), this inner chamber all communicates with through hole (6-1) on lockhole (5-1) and the lock body, also be provided with and the extraneous two passes (1-2) that communicates, laterally switch is located at the inner chamber of junction block, in the through hole on lockhole and the lock body, it is a multidiameter, thinner end contacts with the junction block inner chamber by compression spring (2), and its lower end then contacts with the step surface of lockhole.

When key inserts lockhole, by key horizontal switch is upwards boosted, and simultaneously be located at the junction block two passes in connector lug a, b contact, thereby make delayed alarm circuit form the closed-loop path, if in 3 seconds not key open lock and will send chimes of doom, if the clockwise direction key, just can shift horizontal switch onto on the lock core band (1) and horizontal switch (4) by compression spring; Junction block be provided with lockhole (5-1) and lock body on the inner chamber (1-2) that all communicates of through hole (6-1) and the two passes (1-1) that communicates with the external world; Laterally switch is located in the inner chamber of junction block, the through hole and lockhole on the lock body, and its thinner end contacts with the internal chamber wall of junction block by compression spring (2), and it then contacts with step surface in the lockhole than butt end; Laterally switch (4) can contact with two connector lug a, b in the delayed alarm circuit by the two passes on the junction block (1-1), and laterally switch (4) is an electric conductor, and junction block (1) is an isolator.

The utility model is simple in structure, and is easy to operate, and theftproof is strong, and safety factor height, cost are low, and when the thief unblanks and key is forgotten to send chimes of doom locking Shi Douhui, reminds people is noted, in case thievery takes place.

Below in conjunction with accompanying drawing the utility model is described further:

The main pseudosection of a kind of structure that description of drawings: Fig. 1 combines with horizontal switch and junction block for lock body.

Fig. 2 is the A-A sectional view of Fig. 1

The main pseudosection of the another kind of structure that Fig. 3 combines with horizontal switch and junction block for lock body

Fig. 4 is the B-B sectional view of Fig. 3

Fig. 5 is the delayed alarm circuit schematic diagram

As seen from Figure 1, Figure 2, this lockset comprises lock body (6), lock core (5), lock (9), spring (8), lead (7), on lock body (6), be provided with the electronic delay warning device, it comprises electronic delay warning circuit, junction block and horizontal switch, junction block (1) is packed in the groove on the lock body (6) by bolt (3), junction block (1) is provided with inner chamber (1-2), this inner chamber is relative with lockhole and communicate, communicate with the external world but also be provided with two passes (1-1), laterally open in the groove on inclined-plane, thereby cut off circuit.

Fig. 5 is two kinds of spendable electronic delay warning circuits of structure of this lockset schematic diagram, wherein dc source V _LBe 12V; Six

1,6,2,4,8,3 of integrated package NE555: filter capacitor C ₁Be 16V, 100 μ F; Resistance R ₂Be 100 Ω, music block IC, loudspeaker are pressed the end of a thread a, b for two; Biasing resistor R ₁Be 20K.This circuit contacts in the two passes of junction block with two connector lug a, b by horizontal switch or does not contact control circuit, is in two kinds of duties of closed and disconnected, and delays time after connecting circuit and just send chimes of doom 3 seconds.
