Abstract
The utility model relates to an anti-theft air intake tube of the motorcycle engine, comprising a common air intake tube 1. The utility model is characterized in that: a lock tube 2 is arranged on the outer wall of the air intake tube 1, the inner wall of the lock tube 2 is radially provided with a limited ring groove 4 and is axially provided with slide-ways, the slide-ways extend to the inner side of the air intake tube 1 and form a ring groove in the air intake tube 1, and the ring groove and the slide-ways at both sides of the lock tube 2 compose a lock groove 3. One end of the lock tube 2 is cast and connected with the side wall of the air intake tube 1, and the other end is provided with an outer screw 5. The utility model adapts to the placement of the locking mechanism, benefits the displacement of the locking mechanism in the tube, and ensures the locking mechanism to effectively control the switch-on and the switch-off of the air intake path of the motorcycle engine through moving, and therefore, the anti-theft air intake tube of the motorcycle engine can prevent the thief from stealing the motorcycle by driving.
Description
Technical field:
The utility model relates to a kind of engine fittings, especially the antitheft suction tude of motorcycle engine.
Background technique:
At present, stolen in order to prevent motorcycle, people have designed various anti-theft device for motorcycle, decide device, electronic vibration warning device, power switch lock and front and back wheels locking device or the like as Steering handle lock.Though these anti-theft devices have certain antitheft effect separately, but their common defects is an anti-theft device, and relative motorcycle is self-existent, after anti-theft device is damaged, can't influence the mobility of car load, therefore, robber person will utilize this point, after earlier anti-theft device being destroyed, car is driven away again.For from the antitheft effect of car load mobility performance, applied for that Chinese patent, application number are 200420033109.7 in person, it is that suction port in motorcycle engine is provided with a kind of antitheft fastener device, in case suction port is locked, motor is with regard to fail to start, and car just can't drive away.In order to adapt to the installation of this antitheft fastener device, must improve the available engine suction tude, because of existing motorcycle engine suction tude is the straight-through tube structure, it can't install antitheft fastener device at engine intake.
The model utility content:
The purpose of this utility model provides a kind of antitheft suction tude of motorcycle engine that antitheft locking mechanism is effectively worked in engine air inlet tube, displacement by the control locking mechanism, realize the through and off of mixed oil and gas in the intake duct, reach the purpose that can the control motor normally start.
The purpose of this utility model is achieved in that the antitheft suction tude of a kind of motorcycle engine of design, it comprises common suction tude, its difference is: the outer wall of suction tude is provided with the lock pipe, radially have limited ring groove at the lock inner tube wall, axially have chute, this chute extends in the suction tude, and forms the annular groove in the suction tude, and this annular groove constitutes locked groove with the chute of lock pipe both sides.
Suction tude described in the utility model helps locking mechanism and is placed in the pipe, when the active part of the locking mechanism in being positioned over lock pipe is free to slide in the annular groove of suction tude along locked groove, and intake duct formation closed state, intake duct is closed; In the time of in the active part of locking mechanism is return the lock pipe, intake duct is opened, and the limited ring groove in the lock pipe plays the role of positioning to locking mechanism.Like this,, realize the through and off of mixed oil and gas in the intake duct, reach the purpose that can the control motor normally start by the displacement of control locking mechanism.
The utility model has the advantages that: can adapt to locking mechanism and place, help locking mechanism, guarantee locking mechanism by the mobile through and off of effectively controlling engine inlets, thereby prevent that the thief from driving to steal motorcycle at the pipe intrinsic displacement.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to figure;
Fig. 4 is the structural representation that locking mechanism is installed.
Embodiment:
Please see Figure 1, Fig. 2, Fig. 3, the utility model mainly is made of suction tude 1, lock pipe 2, locked groove 3, limited ring groove 4, outside thread 5, annexation between them is: the outer wall of suction tude 1 is provided with lock pipe 2, radially have limited ring groove 4 at lock pipe 2 inwalls, axially have chute, this chute extends in the suction tude 1, and forms the annular groove in the suction tude 1, and this annular groove constitutes locked groove 3 with the chute of lock pipe 2 both sides.
Fig. 1 is a kind of embodiment of the present utility model, and the sidewall that it will lock pipe 2 one ends and suction tude 1 is cast and is connected, and the other end is provided with outside thread 5.This end adds Sealing with threaded cap, prevents the gas leakage of lock pipe.This embodiment is lock pipe 2 oblique being arranged on suction tude 1 outer wall, and the angle that extends axially locked groove 3 and the shaft axis of suction tude 1 to the suction tude 1 by lock pipe 2 equals to lock the angle of pipe 2 and suction tude 1.
As shown in Figure 4: in antitheft suction tude locking mechanism is installed, this locking mechanism is by lock body 8, dead bolt 9, pin 10, locking plate 11 compositions such as grade.Locking plate 11 links to each other with lock body 8 by pin 10; Dead bolt 9 is connected together with lock body, and between lock body 8 and locking plate.Rotating lock tongue 9 is to locked groove 3 positions, lock body 8 just can slide along locked groove 3 at lock pipe 2, when dead bolt 9 is followed lock body 8 when sliding into annular groove 4 near the intake duct end, locking plate 11 just injects 3 li of locked grooves on the intake duct 1, sealing intake duct 1, allow gas can not enter the firing chamber of motor, motor can't normally be started, play antitheft effect by intake duct; Simultaneously rotating lock tongue 9 sticks into 4 li of annular grooves, and locking lock body 8 allows the locking plate 11 can not be free movable, guarantees that intake duct 1 sealing is reliable.Opening intake duct 1 allows when gas is smooth and easy to be passed through, rotating lock tongue 9 is to locked groove 3, pulling lock body 8, align with the annular groove 4 of threaded end up to dead bolt 9, rotating lock tongue 9 sticks into annular groove 4, locking lock body 8, at this moment locking plate 11 withdraws from the locked groove 3 of suction tude with lock body 8, unimpeded fully up to suction tude, smooth and easy the passing through of gas energy makes and starts function normally to start.
