The specific embodiment

About the present invention reaches above-mentioned application target and effect, the technological means that adopts is hereby enumerated better feasible embodiment, and coordinates shown in accompanying drawing, and details are as follows:

embodiments of the invention, see also Fig. 1, shown in Figure 2, mainly be provided with a body 1, the downward curved arc in the both sides of this body 1 is provided with holding part 10, this body 1 is provided with a lock 2, and this lock 2 is provided with a locking bar jack 20, is provided with caulking groove 21 in the bottom of this locking bar jack 20, one side of this lock 2 is provided with a projection seat 22, and this projection seat 22 is provided with a location perforation 23, one locking bar 3, be located on this lock 2, one end of this locking bar 3 is provided with lock core base 30, this lock core base 30 is provided with a room 31, relatively be provided with a perforation 32 that runs through this room 31 on the wall of this lock core base 30, be provided with location inlay 33 in this perforation 32, this location inlay 33 is steel ball, separately be provided with a pin-and-hole 34 that runs through this room 31 on the wall of this lock core base 30, be equipped with a latch 35 in this pin-and-hole 34, one core 4 is located in this room 31, this core 4 is provided with a key hole 40, the bottom of this core 4 is provided with one and turns 41, these relative two sides of 41 of turning are tangent plane 42, these relatively another two sides of 41 of turning are cambered surface 43, wall in this core 4 is provided with a pin-and-hole 44, so, be the structure of an automobile steering lock.

during assembling, see also Fig. 1～shown in Figure 4, first core 4 is established in the room 31 of lock core base 30, make pin-and-hole 44 on core 4 walls be aligned with pin-and-hole 34 on lock core base 30 walls, latch 35 is inserted in this a plurality of pin-and-holes 34, in 44, core 4 can be fixed in

lock core base

30, 41 the cambered surface 43 of turning of core 4 bottoms is held in the location inlay 33 in the perforation 32 of lock core base 30, to locate inlay 33 outwards holds, location inlay 33 is protruded from the wall of lock core base 30, so, can complete the combination of this core 4 and locking bar 3, this locking bar 3 can be inserted in the positional punch 23 on the projection seat 22 of lock 2, this locking bar 3 is placed on body 1, as shown in Figure 3.

when wish is used, see also Fig. 4, shown in Figure 6, only body 1 must be covered on bearing circle 6, make the holding part 10 of body 1 dual-side be held in the edge of bearing circle 6, lock 2 on body 1 is positioned at permanent seat 60 tops of bearing circle 6, positional punch on the projection seat 22 of lock 2 one sides 23 takes out with locking bar 3 again, locking bar 3 is inserted in the locking bar jack 20 of lock 2, make this locking bar 3 convexedly stretch in the below of bearing circle 6 downwards, this locking bar 3 also is held in permanent seat 60 outer walls (as shown in Figure 6) of bearing circle 6, 30 of the lock core bases of locking bar 3 upper ends are located in the locking bar jack 20 of lock 2, rely on key 5 to be inserted in the key hole 40 of core 4, and screw key 5 drives 41 rotations of turning of core 4 bottoms, 41 the cambered surface 43 of turning is with the outside pushing tow of location inlay 33 in lock core base 30, make the part of locating inlay 33 protrude out the outside wall surface of lock core base 30, and be embedded in the caulking groove 21 of lock 2, lock core base 30 is positioned in the locking bar jack 20 of lock 2, and on the permanent seat 60 that locking bar 3 is supported be positioned bearing circle 6, so, can complete the action of locking, and be held on permanent seat 60 by locking bar 3, bearing circle 6 strong fixs can't be able to be rotated, can really reach antitheft effect, in addition, rely on the cover of body 1 to be established, the safety air bag of being located on bearing circle 6 can be covered protection, can prevent that burglar's destruction direction dish 6 from stealing safety air bag.

when wanting release, see also Fig. 3, shown in Figure 5, only must be inserted in key 5 the interior rotation of key hole 40 of core 4, drive turn 41 the rotation, 43 of the cambered surfaces on 41 of turning are revolved to move and are broken away from inlay 33 positions, location, location inlay 33 is no longer supported, the tangent plane 42 of turning on 41 is aligned with location inlay 33, make location inlay 33 and turn and be formed with spacing between 41, when locking bar 3 is upwards pulled out, 33 of location inlays on its lock core base 30 are subjected to locking bar jack 20 supporting of internal face and inside contract, 33 of the inlays in location can break away from the caulking groove 21 of lock 2, the locking bar jack 20 of locking bar 3 from lock 2 upwards can be extracted, again body 1 is taken off on bearing circle 6, so, can complete the action of release, again the locking bar 3 that takes off on self-lock rod jack 20 is inserted in the positional punch 23 on the projection seat 22 of lock 2 one sides, locking bar 2 is placed on body 1, using, all very convenient in harvesting.

In sum, the present invention has reached desired application target and effect really, and more desirable, practical for it than prior art, yet, above-described embodiment is only to be specifically described for preferred embodiment of the present invention, this embodiment limits claim of the present invention, and other does not break away from the equalization completed under disclosed technological means and changes and modify such as, all should be contained in the claim that the present invention contains.
