Description

Automobile steering lock

Technical field

The utility model relates to vehicular spare parts technical field, particularly a kind of automobile steering lock.

Background technology

Handle lock is automobile actv. anti-theft tool, for bearing circle is afforded protection from theft, by people's know with common.Handle lock of a great variety, configurations.There is in the market a kind of handle lock, as depicted in figs. 1 and 2, its structure comprises the disk body 2 coordinating with vehicle steering 1, the lockset matching with disk body 2, the two ends extension of described disk body 2 is provided with the arc portion 4 that can cover at bearing circle 1 outer peripheral edges, the upper surface of disk body 2 is provided with several through the locked groove 3 of its lower surface, described lockset comprises locking pipe 5, can be inserted in the expansion link 8 in locking pipe 5, locking pipe 5 and expansion link 8 are respectively arranged with a latch hook 7 coordinating with locked groove 3, on expansion link 8, be provided with some lockholes 9, on locking pipe 5, be provided with the lock core 6 coordinating with lockhole 9.During use, first disk body 2 is located on bearing circle 1, arc portion 4 covers at the outer peripheral edges of bearing circle, and expansion link 8 is inserted in locking pipe 5, make again the latch hook 7 of locking pipe 5 and expansion link 8 insert respectively in corresponding locked groove 3, make latch hook 7 catch on the inner peripheral of bearing circle, and then to two ends, pull respectively locking pipe 5 and expansion link 8 to end position, then by lock core 6, coordinate with lockhole 9, locking pipe 5 is fixedly connected with expansion link 8, and now bearing circle forms lock-out state under the mating reaction of latch hook 7 and arc portion 4.Yet, above-mentioned handle lock is unreasonable because structure arranges, conventionally there is in actual use following defect: first, owing to locking pipe 5 and expansion link 8, be separate type, when using, expansion link 8 need to be inserted and locks in pipe 5, after use finishes, need again expansion link 8 to be extracted in locking pipe 5, cause on the one hand using comparatively inconvenience, on the other hand, because expansion link can be extracted from locking pipe, thereby easily cause the generation of expansion link 8 Loss; The second, owing to locking pipe 5 and expansion link 8, a latch hook 7 is all only set, when latch hook 7 and bearing circle 1 inner edge are failed close contact, if now by the sawed-off one section of breach of bearing circle 1, together with disk body 2, rotate to an angle again, can make latch hook 7 deviate from breach, make bearing circle 1 no longer locked; The 3rd, because latch hook 7 is separately positioned on locking pipe 5 and expansion link 8, when lockset coordinates installation with disk body 2, area of contact between disk body 2 and locking pipe 5, between disk body 2 and expansion link 8 is all less, as shown in Figure 2, thereby easily cause arc portion 4 to be pulled open by force by instruments such as clamp, large bottle openers, cause safety performance lower.
