Abstract

The utility model discloses an electronic anti-burglar lock which can be widely used for various bicycles and motorcycles. The electronic anti-burglar lock mainly comprises a lock body, a U-shaped lock rod and an anti-burglar system arranged in the lock body. The anti-burglar system mainly comprises a DC supply, a switch, a protecting device and a radio transmitting module. When the lock rod is inserted into a lock hole, the supply, the switch, the protecting device and the lock rod immediately form a normal locking loop. When someone shears the lock rod or uses external force to hit the lock body, a fuse holder structure is destroyed and the normal locking loop is shut off, then the radio transmitting module starts and transmits radio waves with a certain frequency, and in the effective distance, the owner can alarm through a corresponding carry-on receiver and refer that someone opens the lock abnormally, so as to achieve the purpose of anti-burglary.

(5) specific embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3 is among the figure: 1-lock body, 2-U shape locking bar, 3-first lockhole, 4-second lockhole, 5-keyhole, the 6-dead bolt hole, 7-first contact, 8-second contact, 9-the 3rd contact, 10-insulating layer, 11-moving contact, 12-locking bar inside conductor, 13-recess, 14-dc source, the 15-switch, 16-radio transmission module, 17-first contact is connected lead with power supply, and 18-second contact is connected lead with switch, the square safety box of 19-, 20-porcelain rod, 21-porcelain rod is drawn lead, and 22-radio transmission module is connected lead with switch, 23-the 4th contact, 24-the 4th contact is connected lead with the radio transmission module.

The utility model mainly comprises lock body (1), U-shape sword iron (2) inserts respectively in first lockhole, second lockhole (3,4), lock body one side is provided with keyhole (5), dead bolt hole (6), be provided with two conductive contacts i.e. first contact, second contact (7,8) in the bottom of first lockhole, wherein first contact (7) is made of inside and outside two-layer electroconductive elastic sheet, leave certain interval between the two-layer shell fragment, second lockhole (4) bottom also is provided with the 3rd contact (9), is insulating layer (10) around the above-mentioned contact.Front end at U-shape sword iron (2) is equipped with and aforementioned lockhole bottom second contact (8) and the corresponding moving contact of the 3rd contact (9) (11), and the lead (12) that forms path with the front end contact is housed in the locking bar.Be insulating layer (10) around above-mentioned contact and the lead, locking bar one side is provided with the recess also corresponding with dead bolt (13).

Be provided with burglary-resisting system in the lock body, it comprises dc source (14), switch (15), safeties, radio transmission module (16), the outer shell fragment in aforementioned first contact links to each other with lead (17) with described positive source, and second contact links to each other with lead (18) with switch.Described safeties are a square box body (19) consistent with the lock body height, generally make by duroplasts, frangible porcelain rod (20) is housed in the box body, porcelain rod center is an electric conductor, is generally conduction high-carbon steel, and the porcelain rod is to be fixed on box inner opposite angle line position the best, lead (21) is drawn at its two ends respectively, wherein an end is connected with described switch, and the other end links to each other with the 3rd contact, and the radio transmission module also links to each other with lead (22) with switch.For increasing signal of telecommunication transmitting range, in second lockhole outside the 4th contact (23) is housed, this contact links to each other with lead (24) with the radio transmission module, insert second lockhole with hour locking lever after, this contact also with the locking bar conducting, can reach the purpose that increases the electric wave transmission range.
