The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.

Automobile anti-theft lock as shown in Figure 1 comprises guard shield 1, lock core body 2, lock bridge 3 and top handle 4; Described top handle 4 is in the shape of the letter V, and the open end of top handle 4 is welded on the guard shield 1; As depicted in figs. 1 and 2, guard shield 1 comprises U-shaped front end 11 and the U-shaped rear end 12 after the bending, and the U-shaped front end is near top handle 4, and perforation 13 before having on U-shaped front end 11 has back perforation 14 on the U-shaped rear end, and preceding perforation 13 is parallel with the axis of back perforation 14; As shown in Figure 4, lock core body 2 is made of metal casting 21, lock core 22 and locking mechanism 23, lock core 22 and locking mechanism 23 are installed in the metal casting 21, metal casting 21 is mounted on the U-shaped front end 11 by welding or screw, have inserting hole 24 on metal casting 21, the axis of inserting hole 24 is parallel with the axis of preceding perforation 13; As shown in Figure 2, described lock bridge 3 comprises two interspersed posts 31 and the connecting portion 32 that is connected interspersed post 31, and in the utility model, lock bridge 3 is the U font, has locked groove 33 on the open end of U font lock bridge 3; For better protection lock core body 2 is not destroyed, be covered with can 5 at lock core body 2, can 5 is welded on the U-shaped front end, has opened the hole that is inserted on the lock core 3 for key on the can 5 and has stitched 51; In order to protect and theftproof lock attractive in appearance, at guard shield 1, lock core body 2, lock bridge 3 and top handle 4 parcel one deck protection skin (not shown); For locking mechanism 23 is resetted, the locking mechanism place is provided with spring 10 in metal casting 21.

As Fig. 1 and shown in Figure 6, when using automobile anti-theft lock, guard shield 1 is placed on the outer toroid 6 of steering wheel, the opening of guard shield 1 is towards the center of steering wheel, and top handle 4 withstands on the instrument desk of automobile, then, with lock bridge 3 earlier after back perforation 14 and preceding perforation 13 be inserted in the lock core body 2 in the inserting hole 24, then, allow locking mechanism 23 be stuck in the locked groove 33, thereby play the effect of locking vehicle steering by operation lock core 22.

As Fig. 6, the U-shaped guard shield with outer toroid 6 three bread of steering wheel round, steering wheel can not be seesawed and move downward, after locking lock bridge 3, steering wheel can not be moved upward, again because two interspersed posts 31 are in the both sides of vehicle steering connecting portion 7, therefore, steering wheel can not side-to-side movement; Because top handle 4 withstands on the instrument desk, therefore, can prevent the rotation of steering wheel, thereby play antitheft effect.

As Fig. 1,2 and shown in Figure 6, because locked groove 33 is opened on the end away from the interspersed post 31 of connecting portion 32, lock core body 2 is installed on the U-shaped front end 11, when the bigger power of effect is on guard shield 1, because the locking mechanism 23 in the lock core body 2 is stuck in the locked groove 33, U-shaped front end 11 and U-shaped rear end 12 are subjected to the constraint of lock bridge 3, therefore, U-shaped front end 11 and U-shaped rear end 12 are not easy to open and produce plastic strain, the end of U-shaped lock bridge can not break away from U-shaped front end 11 yet and cause theftproof lock is taken away from steering wheel, compared with prior art, the automobile anti-theft lock of this structure is difficult for destroyed, has improved the theftproof performance to automobile.
