Abstract

The present invention provides a motorcycle engine with an antitheft lock device. The present invention is mainly composed of a cylinder end, a cylinder body and a box body, wherein an air inlet passage 4 is arranged on the cylinder end. The present invention has the structural characteristics that a barrier sheet 5 is arranged in the air inlet passage 4 in a radical direction; a lock body installation base 6 is arranged on the outer side wall of the air inlet passage 4; one end of the barrier sheet 5 extends out of the side wall of the air inlet passage 4 and is connected with a lock body 7 arranged in the lock body installation base 6. The barrier sheet and the lock body of the present invention are difficult to damage by thieves; when the lock body is not unlocked and the rotation lock body is damaged, the motorcycle thieves can not start motorcycles to drive the motorcycles away; lug bosses and grooves which are convexly and concavely matched are respectively arranged on an engagement surface between the cylinder end and the cylinder body and an engagement surface between the cylinder body and the box body, so components arranged on the engine or above the engine have no interchangeability with general engines, and the antitheft function is enhanced.

Description

The motorcycle engine of band anti-theft lock device

Technical field

The present invention relates to a kind of motorcycle engine, especially with the motorcycle engine of anti-theft lock device.

Background technique

At present, stolen in order to prevent motorcycle, people have designed various anti-theft device for motorcycle, wherein mainly contain Steering handle lock and decide device, electronic vibration warning device, power switch lock and front and back wheels locking device etc.They all have certain anti-theft effect separately, but also have certain defective.Wherein, Steering handle lock is decided device and front and back wheels locking device easily by outside destroy, electronic vibration warning device sensitivity instability, the car owner is benumbed, the circuitry lines of power switch lock is also therefore destroyed easily and lost efficacy, and the installation of these several anti-theft devices all is that relative motorcycle is self-existent, therefore is easy to be destroyed by the thief, can't influence the mobility of car load after the destroyed inefficacy of anti-theft device, thereby just can drive away car easily after the car stealer is gone smoothly.

Summary of the invention

The purpose of this invention is to provide a kind of motorcycle engine with anti-theft lock device, it is destroyed easily to solve existing anti-theft device for motorcycle, the problem that just can drive away car easily after the car stealer goes smoothly.

Technological scheme of the present invention is: it comprises cylinder head, cylinder body and casing, wherein on the cylinder head intake duct is arranged, it is characterized in that: in intake duct, radially be provided with catch, the outer side wall of intake duct is provided with the lock body fitting seat, and an end of catch stretches out the sidewall of intake duct and links to each other with lock body in being installed in the lock body fitting seat.

Be provided with boss and the groove that convex-concave matches respectively between cylinder head and the cylinder body and on the mating face between cylinder body and the casing.

Radially be provided with catch in the intake duct among the present invention, one end of catch stretches out the sidewall of intake duct and links to each other with lock body in being installed in the lock body fitting seat, the switching of catch may command intake duct under the effect of lock body, thereby the startup of control motor, catch is in intake duct, and lock body fitting seat and cylinder head are made as one, the person destroys to be not easy the stolen car, even lock body does not suffer car stealer's destruction when unblanking, intake duct also is in closed condition, the car stealer can't ato unit, thereby reaches antitheft purpose; Being provided with boss and the groove that convex-concave matches respectively between cylinder head and the cylinder body and on the mating face between cylinder body and the casing, make motor with upper-part and general purpose engine non-interchangeability, thereby strengthen anti-theft feature.

Advantage of the present invention is: catch and lock body are not easy to be destroyed by the thief, even lock body is not destroyed when unblanking, the car stealer can not drive away the car startup.

Motor is with upper-part and general purpose engine non-interchangeability, even stolenly also can't use.

Embodiment

As Fig. 1, Fig. 2 and shown in Figure 4: the present invention mainly is made up of cylinder head 1, cylinder body 2, casing 3, intake duct 4, catch 5, lock body fitting seat 6 and lock body 7, wherein on the cylinder head 1 intake duct 4 is arranged, its structural feature is: radially be provided with catch 5 in intake duct 4, the outer side wall of intake duct 4 is provided with lock body fitting seat 6, and the sidewall that an end of catch 5 stretches out intake duct 4 links to each other with lock body 7 in being installed in lock body fitting seat 6.

Embodiment 1: as shown in Figures 2 and 3, its structural feature is: catch 5 is circular thin piece, its two ends are supported on the sidewall in the intake duct 4 by guide 8, and the two ends of catch 5 can be rotated guide 8 in, and an end of catch 5 stretches out guide 8 and is installed in the interior lock body 7 of lock body fitting seat 6 and links to each other.The internal diameter of intake duct 4 outer end portion is less than the internal diameter that catch 5 places are set, and catch 5 is not easy the stolen car, and the person takes out in intake duct 4.Being provided with boss 15 and the groove 16 that two groups of convex-concaves match respectively between cylinder head 1 and the cylinder body 2 and on the mating face between cylinder body 2 and the casing 3, make motor with upper-part and general purpose engine non-interchangeability, thereby strengthen anti-theft feature.

Working principle: when needs use motorcycle, insert the lock core of lock body 7 and rotate 90 ° with key, the catch 5 in the intake duct 4 also rotate 90 ° thereupon, go to the parallel axes with intake duct 4, and engine charge is unimpeded, but motor proper functioning (as Fig. 2); When motorcycle does not use, rotate catch 5 and rotate 90 ° with the lock core of lock body 7, go to the axis normal with intake duct 4, block suction port, motor can not be activated, thereby plays antitheft effect (as Fig. 3).

Embodiment 2: as Fig. 4, Fig. 5, Figure 6 and Figure 7, its structural feature is: be provided with limited impression 9 on the tube wall of intake duct 4 and lock body fitting seat 6, catch 5 is installed in the limited impression 9, and the lock pin 10 of rotation is arranged on lock body 7.The tube wall of lock body fitting seat 6 is provided with and rotates lock pin 10 corresponding upper and lower lock pin grooves 11,12, be provided with locking closure 13 in the outer end of lock body fitting seat 6, the end that lock body 7 links to each other with catch 5 is provided with positive stop lug boss 14, make lock body 7 be inverted T-shape, its underpart is a positive stop lug boss 14, positive stop lug boss 14 can prevent that lock body 7 landings from going out lock body fitting seat 6, described catch 5 is bottom thin pieces of rectangular for arc, and its top adopts modes such as welding, interlocking or grafting to be connected with lock body 7.Be provided with boss 15 and the groove 16 that two groups of convex-concaves match respectively between cylinder head 1 and the cylinder body 2 and on the mating face between cylinder body 2 and the casing 3.
