Embodiment

In order further to explain the technological scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

As Fig. 1-shown in Figure 4 for this case have triple anti-theft features in I-shaped automobile nut wheel lock, it comprises nut body 1, antitheft inner cap 2 and antitheft enclosing cover 3, wherein:

Above-mentioned nut body 1 is the circular cone structure of hollow and back-end sealing; On the end face of this circular cone structure, be concaved with the first former groove 120; The preferred embodiment that the utility model provides; As shown in Figure 2, the interior contour pattern of this first former groove 120 is I-shaped groove structure, and conventional instrument can't implement effectively to twist the effect of revolving to it.

Above-mentioned antitheft inner cap 2; It establishes with heavy that mode is adaptive to be arranged on the above-mentioned nut body 1, and particularly, the notch 121 of the first former groove 120 is provided with internal thread; Corresponding antitheft inner cap 2 is the cylinder type shape; Form on its sidewall and the corresponding outside thread 21 of above-mentioned internal thread, antitheft inner cap 2 is adaptive be arranged in the notch 121 after, the outer side surface of antitheft inner cap 2 flushes with the end face that is the nut body 1 of circular cone; Be concaved with the second former groove 22 on the outer side surface of antitheft inner cap 2, preferred embodiment is as shown in Figure 3, is the former groove that profile is letter " E " in, and in like manner conventional instrument can't implement effectively to twist the effect of revolving to it.

Above-mentioned antitheft enclosing cover 3 is circular cone structure, which is provided with the internal thread (not shown); The top of corresponding nut body 1 is provided with outside thread 122; The two suitable screwing togather, the enclosing cover 3 of then guarding against theft is located on the nut body 1, especially; Form a ring-shaped step between the sidewall of outside thread 122 and nut body 1; The external diameter value of ring-shaped step equates on bottom surface external diameter value and the nut body 1 of the circular cone structure of antitheft enclosing cover 3, and the base angle number of degrees value of the circular cone structure on the base angle number of degrees value of the circular cone structure of the enclosing cover 3 of guarding against theft and the nut body 1 equates, thus after the enclosing cover 3 of guarding against theft is arranged in the top of nut body 1; The ring-shaped step of the bottom surface of said antitheft enclosing cover 3 and nut body 1 is inconsistent, and antitheft enclosing cover 3 and nut body 1 element of cone separately are on same straight line; Form the 3rd former groove 31 of a male structure body 310 on the outer side surface of antitheft enclosing cover 3; Promptly the female mould structure of the 3rd former groove 31 is formed by described male structure body 310, and this male structure body 310 is the male structure body of band numeral, in the specific embodiment; As shown in Figure 4; This male structure body is the solid male structure body of a band numeral " 42 ", and then the 3rd former groove 31 externally is shown as special-shaped concaveconvex structure, and conventional instrument can't implement effectively to twist the effect of revolving to it.

Above-mentioned protective hat 4; Process by rubber or plastic cement; It comprises cap head 41; Form on this cap head 41 and the suitable projection 42 of the 3rd former groove 31, the setting of protective hat 4 both can avoid miniature body such as water body or dust to get in the 3rd former groove 31 and the normal use of influence antitheft enclosing cover 3, also having strengthened the aesthetic property of antitheft wheel lock.

As Fig. 5-8 for a kind of be used for above-mentioned have triple anti-theft features in the private key of I-shaped automobile nut wheel lock; It is the connecting rod 5 of a T type; Three free ends of this connecting rod 5 respectively are provided with an outer side wall and are hexagonal first, second and

third tin

51,52,53; This first tin 51, second tins 52 end respectively convex with one respectively with the above-mentioned first former groove 120, the second former groove 22 the be complementary corresponding first formpiston piece 54, the second formpiston piece 55; Three tin 53 end be provided with can head into above-mentioned the 3rd former groove 31 and corresponding with it with male structure body 310 the 3rd chimeric formpiston piece 56 that is complementary; Corresponding the foregoing description, the external frame of this first formpiston piece 54 is I-shaped shape, the interior profile phase of its external frame and the above-mentioned first former groove 120 coincide and matees; The second formpiston piece 55 is the formpiston projection of reverse side letter " E " for external frame; The interior profile phase of its external frame and the above-mentioned second former groove 22 coupling of coincideing, the 3rd formpiston piece 56 is the formpiston projection of the reverse side structure of band numeral " 42 ", the external frame of profile and above-mentioned male structure body 310 coupling that matches in it.

After the triple anti-theft automotive nut wheel of the utility model lock is installed; Because nut body 1 all is the smooth circular cone structure that does not have the corner with the outer side wall of antitheft enclosing cover 3, conventional extracting tool can't effectively tighten and twisting action this nut body 1 and antitheft enclosing cover 3; First antitheft point of the automobile nut wheel lock of the triple anti-theft features of this case is: on the end face of nut body 1, being concaved with profile is the I-shaped first former groove 120; Conventional instrument can't implement effectively to twist the effect of revolving to it; Second antitheft point is: on the outer side surface of antitheft inner cap 2, be concaved with the second former groove 22 that profile is letter " E "; Conventional instrument also can't implement effectively to twist the effect of revolving to it; The 3rd antitheft point is: the 3rd former groove 31 that on the outer side surface of antitheft enclosing cover 3, forms the solid male structure body 310 of a band numeral " 42 "; In like manner conventional instrument also can't implement effectively to twist the effect of revolving to it, said in each heavy theftproof performance all preferable, then triple antitheft points have promoted the whole anti-theft effect that the nut wheel is locked greatly.

Said private key; Be specifically designed to install and dismantle above-mentioned in I-shaped automobile lock with triple anti-theft automotive nuts wheels; Three free ends of said connecting rod 5 set first, second and

third tin

51,52,53 outer side wall all are hexagonal, and conventional instrument can to its clamping and be done to twist to revolve effect, when dismantling triple antitheft wheel lock; The enclosing cover 3 of dismounting antitheft earlier; With the 3rd formpiston piece 56 adaptive embedding the 3rd former grooves 31, with conventional instrument the first tin 51 is clamped and twist to revolve again and realize making things convenient for the effect of installation or removal nut body, when inner cap 2, nut body 1 are guarded against theft in dismounting successively again; In like manner, utilize the effect for convenience detach of conventional tool implementation with the corresponding adaptive embedding of the second formpiston piece 55, the first formpiston piece 54 second former groove 22, the first former groove 120.

In sum, the utlity model has triple anti-theft features in I-shaped automobile nut wheel lock and private key thereof, it is simple in structure; Must use supporting private key during the dismounting automotive wheel, good anti-theft effect can be used with various vehicle couplings; And; This case is not limited only to be applied on the automobile burglar, can also be applied on other mechanical parts that are fit to assembling, can reach described beneficial effect equally.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
