Description

Folded steering wheel lock

Technical field

The utility model relates to a kind of handle lock.

Background technology

Along with the raising of people's living standard, the application of automobile is more and more extensive, and is also more and more higher to the requirement of automobile anti-theft lock performance.The handle lock of prior art is of all kinds, what have is can not folding volume large, have for reducing that the collection volume is designed to Lockset on steering wheel that a plurality of parts cause using and convenient not when collecting, although the anti-theft column lock that has can fold, but there is defective in fold mechanism, for example, when take off foldable lock under the use state after, the lockset auto-folder crushes user's finger.

Summary of the invention

In order to overcome the defective of Lockset on steering wheel in the prior art, the utility model provide a kind of simple for structure, collection is convenient, the folded steering wheel lock that uses safety can not jam a finger.

For realizing the purpose of foregoing invention, summary of the invention of the present utility model is: a kind of folded steering wheel lock, comprise the parts such as front lock fork, rear lock fork, front locking bar, rear locking bar, lock body shifting block, lock core, dead bolt, it is characterized in that: described front locking bar one end links to each other with front lock fork, the other end links to each other with the lock body shifting block, then locking bar one end links to each other with rear lock fork, and the other end is free end; Lock core is installed in the lock body shifting block; One end of lock body shifting block is cylindrical joint pin, periphery at this joint pin arranges several steel bead grooves, the shape of steel bead groove and size match with steel ball, and this joint pin is socketed in the connecting bore that is arranged on the rear lock fork and can pivots at this connecting bore; Be provided with the steel ball hole in the described connecting bore inwall, the reset elastic element of usefulness of steel ball is placed in the steel ball hole, when the forward and backward locking bar of lockset closed up or opens, described steel ball skidded off and enters successively other adjacent steel bead grooves from previous steel bead groove, thereby forms several gears; Dead bolt is positioned at the cylindrical surface of described joint pin, is provided with the lock tongue slot that matches with size with the dead bolt shape on the inwall of described connecting bore.

The anti-theft column lock that adopts such scheme to make; simple for structure; forward and backward locking bar can be pivoted relative to each other around joint pin and lockset is closed up or open; use and collect convenience, and, owing to be provided with steel ball and steel bead groove on the surface of joint pin; when joint pin pivots in connecting bore; the top of steel ball is from skidding off and enter successively other adjacent steel bead grooves from previous steel bead groove, thereby forms several gears, prevents that front locking bar and rear locking bar auto-folder from jamming a finger.

As further improvement of the utility model, described front locking bar has certain radian, in order to match with the slightly bossed surface of bearing circle.The locking bar top is pressed on the bearing circle before when locking like this, prevents that more effectively lockset from swinging.

Among the figure: front locking bar 1, rear locking bar 2, front lock fork 3, rear lock fork 4, lock body shifting block 5, joint pin 51, steel bead groove 6, steel ball 7, steel ball reposition element 8, lock core 9, dead bolt 10, shutoff bolt 11, mounting 12, tie bolt 13, connecting bore 14, steel ball hole 15.

The specific embodiment

Do not specify structure of the present utility model below in conjunction with accompanying drawing.

Referring to Fig. 4 A, Fig. 4 B, Fig. 4 C.Among the embodiment of the present utility model, lock fork 3 before one end of front locking bar 1 connects, the other end connects lock body shifting block 5, lock core 9 is arranged in lock body shifting block 5, one end of lock body shifting block 5 is joint pins 51 of cylindrical shape, on the surface of this joint pin 51, is provided with dead bolt 10, in addition, the periphery facility at joint pin has several steel bead grooves 6.Lock fork 4 after one end of rear locking bar 2 connects, the other end is free end.Offer a connecting bore 14 that connects in rear lock fork 4, this connecting bore 14 is cylindrical shape, with be positioned at front locking bar 1 lock body shifting block 5 on the shape of joint pin match with size, behind the described connecting bore 14 of joint pin 51 cover accesses, joint pin 51 can pivot in connecting bore 14.Tie bolt 13 is fixed on mounting 12 on the section of joint pin 51, thereby with connecting bore 14 sealings on the rear lock fork 4.Offer a steel ball hole 15 that connects with connecting bore 14 from rear lock fork 4 top sections, steel ball 7 is arranged in steel ball hole 15, and shutoff bolt 11 is pressed to steel ball 7 with the reset elastic element of usefulness of steel ball.When rotating front locking bar 1 and driving lock body shifting block 5 pivot, steel ball 7 slides or rolls on the surface of joint pin 51; After the joint pin 51 pivot certain radian of rotating shifting block 5, steel ball 7 is subjected to the extruding of reposition element 8 to fall into the steel bead groove 6 on joint pin 51 surfaces, forms that anti-theft column lock closes up or the gear when stretching.The quantity of gear is determined by the quantity of steel bead groove 6 on the joint pin 51, for example, can be arranged on 2-8 gear.Owing to be provided with gear, when the lockset that trails takes off from bearing circle, can prevent from pointing the forward and backward locking bar 2 that is automatically closed up and crush, and, when lockset was in collecting state, the existence of gear made the forward and backward locking bar 2 of lockset be in the state that closes up always, was conducive to collect and carry.The reposition element 8 of steel ball can adopt spring.

Inwall at described connecting bore 14 offers dead bolt 10 grooves, and when lockset is in use state lower time, dead bolt 10 inserts in dead bolts 10 grooves, is that lockset is in blocking.

Use state reference map when Fig. 1 is the utility model pinning bearing circle, Fig. 2 is the scheme drawing of the utility model under blocking.Under locking states, the opening of front lock fork 3 and rear lock fork 4 is respectively towards away from the direction at bearing circle center and reverse each other.When on the bearing circle of lockset place the time, lock fork 4 is stuck on the rotating disk of bearing circle before and after it, and bearing circle can not freely rotate, and realizes antitheft purpose.

Under the use state, in order to make the spoke close contact of front locking bar 1 and bearing circle, prevent front locking bar 1 any damage bearing circle that slides on bearing circle, front locking bar 1 slightly can be curved certain radian, coincide with the part of bearing circle central area projection.In addition, front locking bar 1 and rear locking bar 2 can overlap the sheath of epithelium, cotton or foam, the friction before reducing between locking bar 1 and the bearing circle, and more attractive in appearance when making lockset, more comfortable during use.

Fig. 3 is the scheme drawing of the utility model under collecting state, owing to be provided with gear, front locking bar 1 and rear locking bar 2 remain and close up state, collection and easy to carry.
