Specific embodiment

Below in conjunction with accompanying drawing and most preferred embodiment, the utility model is further described.

At first, see also shown in Fig. 1,2, the securing arrangement of the folded steering wheel lock that the utility model embodiment one discloses comprises lock pipe 1, folding pipe 2 and lock tube 3.

Wherein, lock pipe 1 and folding pipe 2 relative outer ends are provided with the hoop hook, are prior art because of binding round hook, and Gu Tuzhong does not express.Lock pipe 1 is linked together by a hinge 4 with the inner of folding pipe 2.Extend to the inner of folding pipe 2 the inner of lock pipe 1, and form a lock 12 on extension, and form the lockhole 11 that a lock mandrel 31 of being convenient to lock tube 3 stretches out on the bottom of lock 12.The lockhole 11 of the inner corresponding lock pipe 1 of folding pipe 2 forms the lockhole 21 of a circle.Two

lockholes

11,21 can be when lock pipe 1 be a straight line with folding pipe 2, and is overlapped.Folding pipe 2 or lock pipe 1 outer end one are extended and are provided with pin (because of pin is a prior art, Gu Tuzhong does not express), so that when locking, form stopping of wheel steering by pin, the lock that the reaches bearing circle effect of pulling.

Lock tube 3 places lock 12.This lock tube 3 can drive its circular lock mandrel 31 by key and stretch out or be retracted into lock housing, when lock mandrel 31 stretches out lock housing, passes the lockhole 11 on the lock pipe 1, when being plugged in the lockhole 21 on the folding pipe 2, just lock pipe 1 and folding pipe 2 is formed the effects of pulling of locking.

The utility model embodiment one applies on the bearing circle, when locking, is under state as shown in Figure 2, and it is stretching with folding pipe 2 to lock pipe 1 earlier, and supports to arrive in inner ring in bearing circle by the hoop hook, and at this moment, two

lockholes

11,21 are overlapped just.The lock mandrel 31 that is driven in the lock tube 3 by key stretches out lock housing again, pass the lockhole of locking on the pipe 1 11 by lock mandrel 31, be plugged in the lockhole 21 on the folding pipe 2, lockset fixedly is directly tabular, as shown in Figure 1, makes whole lockset firmly be placed on the bearing circle, realization is locked, and form stopping of wheel steering by pin, and the lock that the reaches bearing circle effect of pulling, lock operation is convenient, easily.

When unblanking, then under state shown in Figure 1, drive lock mandrel 31 by key and be retracted into lock housing, lock tube 3 is locked pull fixing, lock pipe 1 can bend by hinge with folding pipe 2, as shown in Figure 2, take off, be rotated further lock pipe 1 and folding pipe 2 from bearing circle, be parallel to each other until lock pipe 1 and folding pipe 2, as shown in Figure 3, be the complete rugosity of volume minimum, be convenient to collection.

See also shown in Fig. 4,5, the securing arrangement of the folded steering wheel lock that the utility model embodiment two discloses also comprises lock pipe 1, folding pipe 2 and lock tube 3 again.This embodiment structurally with embodiment one have similar mutually, the two different only be: the lock mandrel 31 ends cross section vertically of lock tube 3 is down " T " font among the embodiment two, lock mandrel 31 stretches out outside the lock housing all the time, and be plugged in the lockhole 11 of lock pipe 1, lock tube 3 can drive its lock mandrel 31 by key and rotate, and the shape of 21 corresponding lock mandrel 31 ends of lockhole on the folding pipe 2 also is down " T " font.

Like this, this embodiment applies on the bearing circle, when locking, be under state as shown in Figure 5, it is stretching with folding pipe 2 to lock pipe 1 earlier, slide in the lockhole 21 of folding pipe 2 in the end of lock mandrel 31, linearly fully until lock pipe 1 with folding pipe 2, and support to arrive in inner ring in bearing circle by the hoop hook, at this moment, two

lockholes

11,21 are overlapped just, and lock mandrel 31 is plugged in the lockhole 21 of folding pipe 2, and lock mandrel 31 ends fall that there are 90 ° of angles in " T " font structure that falls of lockhole 21 on " T " font structure and the folding pipe 2.The lock mandrel 31 that is driven in the lock tube 3 by key rotates again, what make lock mandrel 31 ends falls that the angle between " T " font structure of lockhole 21 is 0 ° on " T " font structure and the folding pipe 2, " T " font end of falling by lock mandrel 31 cooperates with " T " font lockhole 21 that falls that folding is managed on 2, lockset fixedly is directly tabular, as shown in Figure 4, make whole lockset firmly be placed on the bearing circle, realization is locked, and form stopping of wheel steering by pin, the lock that the reaches bearing circle effect of pulling, lock operation is convenient, easily.

When unblanking, then under state shown in Figure 4, driving lock mandrel 31 by key rotates, what make lock mandrel 31 ends falls that the angle between " T " font structure of lockhole 21 is changed to 90 ° by 0 ° on " T " font structure and the folding pipe 2, not locking tube 3 locks between folding pipe 2 and the lock pipe 1 pulls fixing, lock pipe 1 can bend by hinge with folding pipe 2, as shown in Figure 5, take off from bearing circle, be rotated further lock pipe 1 and folding pipe 2, be parallel to each other until lock pipe 1 and folding pipe 2, as shown in Figure 6, the complete rugosity that is the volume minimum is convenient to collection.

In addition, from Fig. 1-6 as seen, lock 12 of the present utility model directly forms on the lock pipe 1, and the part that lock 12 outstanding locks are managed 1 surface is lower, and lock tube 3 is arranged in the lock 12, and is trapped in the lock pipe 1 in lock tube 3 parts.Like this, after the utility model was made, its finished product was compared with the product of prior art, and lines are more smooth, and profile is smaller and more exquisite, attractive in appearance, and the collection of being more convenient for.
