The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further, so that clearerly understand the utility model technical thought required for protection.
As shown in Figure 1, 2, 3, the automobile steering lock for the utility model improvement comprises lock body 1, is used for the lock car antitheft.Described lock body 1 can adopt any one lock on the market, as drawing and pulling type lock or folding lock etc.The front end of lock body 1 is provided with brokenly the window device; Should comprise the pedestal 2 that is arranged on lock body 1, the tup 3 that is arranged on pedestal 2 front ends by broken window device; The point that is provided with on the front end of described tup 3 for hammering glass hits section 31.Because hitting section 31, this point can effectively reduce its area of thrust surface, in the situation that applied pressure remains unchanged, can be convenient to increase its pressure, therefore, when emergency occurring, hit section 31 by the point that utilizes tup 3 and clash into glass, can be convenient to break fast window, thereby win escape and the rescue time of preciousness for trapped personnel in car; And this broken window device is arranged on lock body 1, can save storage space, and conveniently goes out to carry; In addition, it is simple and reliable for structure, and cost of manufacture is low, is conducive to be widely used.
Preferably, the front end of lock body 1 is provided with bar section 11, and this broken window device is arranged in bar section 11.In use, the user can be convenient to control by grip bar section 11 dynamics that it applies.And according to common practise, should can be arranged on any one rigid element of lock body 1 front end by broken window device, but will break the window device is arranged in the bar section 11 of lock body 1, be optimal case of the present utility model, it is convenient to hold, facilitate the user to control the dynamics that it applies, thereby improve the speed of broken window.
As shown in Figure 3, be provided with on the front end of described tup 3 and be cylindrical-conical point and hit section 31.And the structure of hitting section 31 by point rationally is set not only plays and reduces area of thrust surface, increases the effect of pressure, and, also be convenient to processing.
As shown in Fig. 1,4, this broken window device also comprises outside the tup 3 and relatively protecting sleeve 4 that seesaws of tup 3 of movable set; Be provided with the container cavity 41 of installing for tup 3 in described protecting sleeve 4, be provided with internal ring portion 42 in this container cavity 41, be provided with spring 5 between this internal ring portion 42 and pedestal 2, the flexible direction of this spring 5 is consistent with the moving direction of protecting sleeve 4.When broken window device acts on glass, protecting sleeve 4 under the drag effect of glass relatively tup 3 move backward, tup 3 hammerings are on glass, at this moment, the point of tup 3 hits outside section 31 is exposed to; When tup 3 left glass, protecting sleeve 4 automatically reset under the elastic force effect of spring 5, and cover cap is outside tup 3.Therefore, be at tup 3 under the state of non-hammering, can avoid outside tup 3 is directly exposed to by utilizing protecting sleeve 4, damage thereby the point that prevents tup 3 hits 31 pairs of human bodies of section, perhaps object is caused damage.Preferably, described internal ring portion 42 is divided into ante-chamber and back cavity with container cavity 41, also is provided with on protecting sleeve 4 with pedestal 2 leading sections are complementary and inserts chamber 43, and this inserts the rear that chamber 43 is positioned at back cavity; Describedly insert chamber 43 and back cavity is all cylindrical, and insert the internal diameter in chamber 43 greater than the internal diameter of back cavity.By adopting said structure, can be convenient to the maximum mobile range of limiting protecting cover 4.
Described tup 3 is horizontally arranged with rounded flange part 32, and internal ring portion 42 is annular arrangement, and described flange part 32 is positioned at the place ahead of internal ring portion 42, and the external diameter of flange part 32 is greater than the internal diameter of internal ring portion 42.In protecting sleeve 4 reseting procedures, can avoid breaking away from protecting sleeve 4 and tup 3 by adopting said structure.
The rear end of described tup 3 is provided with threaded shank 33, is provided with mounting hole 21 on this pedestal 2, is provided with the negative thread that is complementary with threaded shank 33 in mounting hole 21.And with above-mentioned similar, described pedestal 2 also adopts the mode that is threaded to be connected with lock body 1.By the mode that employing is threaded, can be convenient to dismounting and the replacing of part, thereby reach the purpose of saving resource.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
