CN201506406U - Motor cycle anti-theft lock - Google Patents

Abstract

The utility model provides a motor cycle anti-theft lock which has high anti-theft coefficient; the motor cycle anti-theft lock is improved on three ways: a cover body 2 is covered on the opening of a case body 1 by two stop pins 6, when a sliding block 5 moves to the right side wall of the case body 1 until to the locking position, cap bodies of all the stop pins 6 are arranged below a special-shaped hole 52 to prevent the cover body 2 from being opened under a locking state, that is the first defense line; under a condition that the cover body 2 is opened, as a locking pin 4 is screwed on the sliding block 5 from the outer side of the case body 1 to inside thereof, the locking pin 4 is hard to be dropped off from a steering handle in a traditional damage mode, that is the second defense line; as the right side of the sliding block 5 covers a fixed screw of the case body 1, the case body 1 is hard to be dismounted from a carriage in the locking state, that is the third defense line; by designing the third defense line, the anti-theft purpose is achieved.

Description

A kind of anti-theft lock for motorcycle

Technical field

The utility model relates to a kind of anti-theft lock for motorcycle, and it is installed in and prevents on the motor bike that motor bike from being stolen.

Background technology

Motor bike is a upper notion, and it comprises the motor bike of common gasoline driven, also comprises emerging battery-operated motor cycle.One of main vehicle that motor bike is gone on a journey as people are quite high in some small and medium cities popularity rates, and the stolen phenomenon of motor bike also happens occasionally.The anti-theft column lock that is used on the motor bike arises at the historic moment thus, as the Chinese patent CN201143963Y disclosed vehicle multi-point fastening control device of on November 5th, 2008 bulletin and have the Vehicle locking system of this control device, this multi-point fastening control device comprises the anti-theft column lock of mechanics and the central controlled lock of electric part.The structure of wherein said anti-theft column lock is such: motor bike comprises vehicle frame and is located at the handle that turns on the vehicle frame, described turning to being provided with knock hole, anti-theft column lock promptly is located on the vehicle frame, makes lock pin one end enter knock hole to turning to locking by the lock core that rotates anti-theft column lock.In order to prevent that the thief from prying open anti-theft column lock, the lid of described anti-theft column lock can't be opened under lockup state.But the contriver finds, owing to have the gap between the lid of anti-theft column lock and the box body, only need one can make straight screwdriver insertion box body lid separate with box body with the slit of lid, can pull down the fix screw in the box body this moment, and then whole anti-theft column lock pulled down from vehicle frame, turning to losing locking, the thief can steal motor bike easily, therefore anti-theft lock for motorcycle awaits further perfectly, and antitheft coefficient has to be hoisted.

The utility model content

The purpose of this utility model provides the high anti-theft lock for motorcycle of a kind of antitheft coefficient.

The technical scheme that the utility model adopted is such: a kind of anti-theft lock for motorcycle, comprise box body (1), lid (2), tapered end (3), lock pin (4), slide block (5), two fixing pins (6) and eccentric shaft (7), described box body (1) is the hollow rectangular structure that a side has opening (11), tapered end (3) is located at last that side back to opening (11) of box body (1), slide block (5) is 90 degree beveled structures, one side of slide block (5) is positioned at box body (1) that side adjacent with tapered end (3), slide block (5) is provided with chute (51) and two profile holes (52), the lock core of described tapered end (3) and eccentric shaft (7) one ends are affixed, eccentric shaft (7) other end is located on the described chute (51), described lid (2) is covered on the opening (11) of described box body (1), one end of two fixing pins (6) is fixedly arranged on the madial wall of lid (2) respectively, the free end of two fixing pins (6) is respectively equipped with cap body (61), described each cap body (61) cross each profile hole (52) respectively and be positioned at slide block (5) and box body (1) between, described box body (1) right side wall is provided with pin-and-hole (12), slide block (5) is provided with screw (53), one end of lock pin 4 passes pin-and-hole (12) and revolves and is located on the screw (53), also be provided with at least two fixed orifices (13) on described box body (1) right side wall, described anti-theft column lock is fixedly arranged on the vehicle frame with screw by each fixed orifice (13), and described each fixed orifice (13) is positioned at slide block (5) within the scope of the area of conter institute letter lid on box body (1) right side wall.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: because lid 2 is covered on the opening of box body 1 by two fixing pins 6, when slide block 5 when box body 1 right side wall moves to lock position, the below that the cap body of each fixing pin 6 is positioned at profile hole 52 prevents that lid 2 is opened under lockup state, this is a first line of defence; Under the situation that lid 2 is opened, because lock pin 4 is located on the slide block 5 from box body 1 lateral inward turning, therefore, lock pin 4 is difficult to make it from turning to coming off by the mode that tradition is destroyed, and this is the defence line second time; Because slide block 5 right sides have covered the fix screw of box body 1, so this box body 1 is difficult to pull down from vehicle frame under lockup state, and this is the three lines of defence, reaches theft-proof purpose by constructing this three lines of defence.

Below in conjunction with accompanying drawing the utility model is specified for an embodiment.
