Description

The contractile folding automobile steering lock

Technical field:

The utility model is the theftproof lock that is used on the vehicle steering, and particularly a kind of contractile folding automobile steering lock belongs to five metals lockset manufacturing technology.

Background technology:

Current for protecting automobile not stolen, generally automobile uses to have when stopping the theftproof lock on a kind of lever-type vehicle steering is locked on the vehicle steering, and it is actually with two cards and holds the steering wheel that blocks circle, and it is no longer rotated.Therefore, even if the thief can be car engine, but because steering wheel can not rotate also is futile, automobile leaves to walk, and has reached antitheft purpose.But the theftproof lock of using on this lever-type vehicle steering is a whole piece metal construction, long and heavy, is not easy to carry, take up space again, has more weakness.The utility model is researched and developed for the weakness that overcomes prior art, and this is the background that the utility model produces.

The utility model content:

The purpose of this utility model provides a kind of contractile folding automobile steering lock, it is that automobile steering lock is manufactured fixedly pipe box of an expansion link and, fixedly pipe box is a hollow section, expansion link can fixedly move or be fixed on a certain position in the pipe box, promptly lock core and the dead bolt that is put by rack structure on the expansion link and stationary pipes matches, and dead bolt can block tooth bar and decontrol tooth bar.In addition expansion link and stationary pipes put also be equipped with before folding rod and back folding rod, the preceding folding rod of two stretching, extensions and back folding rod and expansion link and fixedly pipe box then constitute an automobile steering lock, realize locking to vehicle steering.Obsolete the time,, dwindled volume greatly, put, collected and carried all very convenient for shrinking and folded state.The utility model modern design, rational in infrastructure, easy to use, be convenient to the collection.The technical scheme of the utility model technical solution problem is such, inventor's design will make automobile steering lock shrink and to fold, must change system into two to a straight-bar of prior art, and wherein in the body that can be collected in another root, the bat of other two jam steering wheel annulus, can folding when they do not use, do not occupy space, reduced volume as far as possible, be convenient to collection.The inventor has accomplished these some, has realized the design of oneself.The utility model comprises tapered end pedestal, tapered end, lock core, dead bolt, fixedly pipe box, spiral key, coil tension spring, support spring and Capsule, the fixing pipe box of one side socket in the tapered end bottom, its first design feature is fixedly to connect expansion link in the pipe box, folding rod before connecting on expansion link connects the back folding rod on the tapered end pedestal.Its second design feature is that the expansion link rear end has tooth bar, at the expansion link front end " U " shape groove arranged, and preceding folding rod is connected in " U " shape groove by screw and pin at the rear portion of " U " shape groove, is equipped with support spring in preceding folding rod rear end; Be equipped with tapered end on tapered end pedestal top, lock core is arranged in tapered end, be connected with dead bolt in lock core one side; Be provided with the triangle clip slot in tapered end pedestal bottom, be connected the back folding rod with pin by screw in the triangle clip slot, be equipped with support spring in the rear end of back folding rod; When expansion link when the tapered end pedestal is stretched as certain-length, preceding folding rod opens apical grafting and opens the opposite side of apical grafting at vehicle steering at a side, the back folding rod of vehicle steering, the dead bolt apical grafting in the tapered end pedestal on the tooth bar of expansion link with the expansion link locking; Rear end at " U " of expansion link shape groove has position-arresting groove, fixedly pipe box is a hollow section, end assembling coil tension spring at fixing pipe box, fixedly pipe box front end bottom has kidney slot, turn spiral key in lock core, the spiral key unlock deadbolt, dead bolt is withdrawn from the tooth bar on the expansion link, preceding folding rod bounces back in " U " shape groove, expansion link can move back and bounce back to fixedly in the pipe box, and expansion link compression coil tension spring is depressed into the back follower head of folding rod in the kidney slot of fixing pipe box, simultaneously also jam in the position-arresting groove of expansion link lower end, expansion link is lived by stop, and promptly expansion link and back folding rod form self-locking device.Its 3rd design feature is that the front end at expansion link is inlaid with Capsule.In sum, advantage of the present utility model is:＜one 〉, novel in design, rational in infrastructure, expansion link is fixedly moving in the pipe box, and can and rely on lock core and dead bolt to come jam tooth bar and relieving tooth bar to realize the unlatching and the locking of vehicle steering by the rack structure on the expansion link; Folding rod can fold and be collected in the expansion link simultaneously, back folding rod also can folding storage in fixing pipe box one side, thereby reach contraction and fold, dwindled greatly the volume of lockset, collect and carry all very convenient.＜two 〉, in this lockset contraction process, can realize self-locking, guaranteed that each parts are in a stable state, have embodied its advantage more.＜three 〉, easy to use, applied range, not only cart can be used, dolly is available too, being all expansion link can stretch out and shorten apart from the lining certain, and the bigger scope of application and flexibility are arranged.
