Abstract
The invention discloses an anti-theft device for a bicycle. The anti-theft device comprises a lock bolt and a lock. A pin positioning sheet which is a thin sheet is arranged on the upper portion in the lock and provided with a plurality of small through holes, a metal pin is arranged in each small through hole, and the upper end of each metal pin is slightly thicker than the other portion. A flat plate parallel to the pin positioning sheet is arranged below the pin positioning sheet and also provided with a plurality of small through holes, a plurality of permanent magnets are arranged according to the specific positions of the small through holes, an L-shaped lever is arranged below the flat plate, one end of the L-shaped lever is arranged right below the flat plate, the other end of the L-shaped lever is connected with a first spring, the bottom surface of the flat plate is perpendicularly connected with a metal plate, a cross bar is arranged at the bottom of the lock, one end of the cross bar limits the lock bolt, the other end of the cross bar is connected with a second spring, two vertical rods are arranged on the upper side of the cross bar, one of the vertical rods is arranged on the right side of the L-shaped lever, and the other one is arranged on the left side connected with the metal plate below the flat plate. The anti-theft device is high in insurance and solves the problem of high theft rate of bicycles.
Description
Technical field
The present invention relates to a kind of anti-theft device, relate in particular to a kind of theft-proof device for bicycle.
Background technology
Current bicycle lock is on the market common lock mostly, and principle is basic identical, and their core is all circular object, free to rotate.Common lock has a copper core, can see that one side is groove after taking apart above, and another side is row's aperture, is copper post and spring different in size in aperture.Copper major gene ejects half for not stressing at ordinary times, and has stopped the rotation of large copper core.When the key with corresponding inserts, copper post and tooth contact on the key, form a regular curve, and getd out of the way the gap on large copper core, enables to rotate, thereby lock is opened.Visible common lock to open principle fairly simple, so that bicycle is easy to is stolen.
Summary of the invention
In order to address the above problem, the invention provides a kind of theft-proof device for bicycle, its good airproof performance be difficult for entering dust water droplet and safety high.
The present invention is achieved by the following technical solution: a kind of theft-proof device for bicycle, comprise lock bolt and tapered end, it is characterized in that, top in described tapered end arranges certain faller gill, the described faller gill of determining is a thin slice, determine to be provided with on faller gill the aperture of some perforations, in each aperture, place one piece of metal needle, described metal needle upper end is slightly thick, the below of determining faller gill is provided with the flat board parallel with determining faller gill, on flat board, also there is the aperture of some perforations, according to the ad-hoc location of aperture, arrange some permanent magnets, there is a L shaped lever dull and stereotyped below, one end of L shaped lever be positioned at dull and stereotyped under, the other end is connected with a spring, the vertical metal sheet that connects in dull and stereotyped bottom surface, the bottom of described tapered end arranges a cross bar, one end restriction lock bolt of described cross bar, and the other end is connected with No. two springs, and the upside of cross bar is provided with two montants, and a montant is positioned at the right side of L shaped lever, and another montant is positioned at the left side that connects metal sheet under flat board.
The invention has the beneficial effects as follows: the present invention unblanks by Magnetic Induction, greatly improved the safety of bicycle, solved the high problem of bicycle theft rate, this induction lock dustproof and waterproof of while, good looking appearance, easy to use and reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention;
In figure: 1-lock bolt, 2-cross bar, spring of 3-, 4-L shape lever, No. bis-springs of 5-, 6-flat board, 7-tapered end, 8-metal needle, 9-determine faller gill, 10-metal sheet.
The specific embodiment
As shown in Figure 1, a kind of theft-proof device for bicycle, comprise lock bolt 1 and tapered end 7, top in described tapered end 7 arranges certain faller gill 9, the described faller gill 9 of determining is thin slices, determine to be provided with on faller gill 9 aperture of some perforations, in each aperture, place one piece of metal needle 8, described metal needle 8 upper ends are slightly thick, the below of determining faller gill 9 is provided with the flat board parallel with determining faller gill 96, also the aperture that has some perforations on dull and stereotyped 6, according to the ad-hoc location of aperture, arrange some permanent magnets, there is a L shaped lever 4 dull and stereotyped 6 belows, one end of L shaped lever 4 be positioned at dull and stereotyped 6 under, the other end is connected with a spring 3, dull and stereotyped 6 the vertical metal sheet 10 that connects in bottom surface.The bottom of described tapered end 2 arranges a cross bar 2, one end restriction lock bolt 1 of described cross bar 2, the other end is connected with No. two springs 5, and the upside of cross bar 2 is provided with two montants, a montant is positioned at the right side of L shaped lever 4, and another montant is positioned at the dull and stereotyped left side that connects metal sheet 10 for 6 times.
The key of this lock is a hermetic unit of plastic, when key is closely attached on, determines faller gill when top, and metal needle is deflected by magnetic fields, the aperture on the lower end aligned flat board of metal needle.At this moment pull cross bar to the right, L shaped lever rotates under a spring action, and flat board is held up, and connects metal sheet and rise under flat board, and cross bar can be retreated, and so just lock bolt is discharged.Remove key, push to lock bolt, L shaped lever and cross bar set back under spring-force driven dual, and metal needle deflects once again under Action of Gravity Field, and lock returns to again blocking.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, technical spirit according to the present invention, to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention.
