Abstract
The utility model relates to an anti-theft device for a steering wheel of a vehicle, comprising a cylindrical shell (being integrated with a steering wheel) sheathed on the upper end of a rotating rod of a steering gear box. A positioning mechanism is arranged between the shell and the rotating rod, a gear ring is fixed at upper end of the inner wall of the cylindrical shell, a shifting gear is sheathed on the rotating rod, the tail end of a lock cylinder controls the gear and a rack matching mechanism, and the upper end of a rack is matched and contacted with the lower end of the shifting gear. In the utility model, the control of the work of steering wheel is realized by controlling the connection or disconnection between the steering wheel and the rotating rod. For the anti-theft device, the structure is simple, the manufacturing and the implementation are easy, the using effect is good, the damage of the relevant parts caused by forcibly turning the steering wheel under the lock state is avoided, so that the anti-theft device has long service life and beneficial to the application and promotion on various vehicles.
Description
Technical field:
The utility model belongs to the bearing circle technical field of burglary prevention, specifically relates to a kind of steering wheel for vehicle anti-joyride device.
Background technology:
At present at the theft-proof lockset of bearing circle, mostly be to utilize with the fixing dead locking mode of bearing circle bull stick, because the rotating torque of bearing circle itself is very big, if the torsional direction dish just is easy to damage dead bolt by force, even cause the consume of bearing circle parts, become destructive locking structure.
The utility model content:
The utility model is the deficiency that exists at prior art, and a kind of steering wheel for vehicle anti-joyride device that has more practicality is provided.
Technical scheme: a kind of steering wheel for vehicle anti-joyride device, comprise a cylindrical case (cylindrical case and bearing circle one) that is sleeved on direction machine bull stick upper end, be provided with detent mechanism between this shell and the bull stick, the inwall upper end of cylindrical case is fixed with a gear ring, mate the ingear walking gear by energy of spline structure suit and gear ring on the bull stick, lockset also is installed in the cylindrical case, terminal and the set wheel and rack matching mechanism of its lock core center shaft is in transmission connection, the upper end of this tooth bar contacts with walking gear lower end coupling, and bearing circle is fixed on cylindrical case or the gear ring.
Be provided with a special tooth of coupling between walking gear and the gear ring and be used for the location.
The cylindrical case upper end is equipped with horn punch, and the lower end of horn punch is fixed with the pilot bar of band barb, vertically is provided with pilot hole on the gear ring, and pilot bar inserts in the cooresponding pilot hole after being set with spring; In the inner chamber of bull stick upper end elastic top is installed and compresses switch, this elastic top compresses switch and is positioned at the horn punch below.
On the center shaft of lock core end gear is installed, in lockset, is set with a tooth bar that can move up and down, the engagement of wheel and rack coupling.
Described detent mechanism comprises a bearing box that is fixed on the cylindrical case lower end, and flange is set on the bull stick, and flange is positioned at bearing box, on the bull stick of cylindrical case inboard jump ring is installed simultaneously.
The bull stick upper end is equipped with the jump ring of restriction walking gear, also is set with spring on the bull stick between this jump ring and the walking gear.
Beneficial effect: the mode whether the utility model meshes by control walking gear and gear ring, realize being connected or unclamping between bearing circle and the bull stick, bearing circle can drive bull stick and further drive the work of direction machine during connection, when bearing circle and bull stick unclamp, bearing circle is in free state, and the direction machine is not played any control action.By lockset control walking gear is installed on cylindrical case, realize bearing circle work whether control.The utility model is simple in structure, makes easily and implements, and result of use is good, can not caused associated components impaired because of torsional direction dish by force at the state of locking, and long service life is beneficial on various vehicles and applies very much.
Description of drawings:
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is an application scheme drawing of the present utility model.
The specific embodiment:
Embodiment one: referring to Fig. 1, Fig. 2 and Fig. 3, the steering wheel for vehicle anti-joyride device comprises a cylindrical case 1 that is sleeved on direction machine bull stick 2 upper ends, and this shell is connected with bearing circle 17 by hold-down arm.
Be provided with detent mechanism between shell 1 and the bull stick 2, this detent mechanism comprises a bearing box 10 that is fixed on the cylindrical case lower end, and flange 8 is set on the bull stick 2, and flange 8 is positioned at bearing box, and jump ring 12 is installed on the bull stick of cylindrical case inboard simultaneously.The effect of detent mechanism mainly is to guarantee not move axially between bull stick and the shell, realizes that the frame mode of this purpose is various, except said structure is described, other structures can also be arranged, and does not describe in detail.
The inwall upper end of cylindrical case is fixed with a gear ring 3, walking gear 4 of suit on the bull stick 2, the arranged outside spline 7 of this bull stick 2 is provided with the featherway of coupling on the walking gear internal diameter, thereby bull stick 2 only can move axially behind suit with walking gear 4 and can not rotate motion.In addition, consider the habituation location of bearing circle and Vehicular turn, between walking gear 4 and gear ring 3, be provided with a special tooth of coupling, be used to locate 33.
The bull stick upper end is equipped with the jump ring 14 of restriction walking gear, also be set with spring 15 on the bull stick between this jump ring and the walking gear, jump ring 14 can prevent that walking gear from upwards holding out, and spring 15 can guarantee that walking gear 4 falls smoothly under the situation that does not have tooth bar 11 to support.
Embodiment two: referring to Fig. 1 and Fig. 2, content and embodiment one are basic identical, and something in common does not repeat, and different is: do not have jump ring 14 and spring 15, walking gear 4 falls by self gravitation.
