Abstract
The utility model provides an anti-breaking device of an anti-theft lock cylinder. The anti-breaking device of the anti-theft lock cylinder is provided with a poking wheel, a fixing threaded hole is formed below the poking wheel, and a piece of U-type anti-breaking section bar which is matched with the anti-theft lock cylinder in shape is arranged on the bottom of the anti-theft lock cylinder. Compared with the prior art, the anti-breaking device of the anti-theft lock cylinder has the advantages that structure is simple relatively, the U-type anti-breaking section bar which is made of high-strength metal protects the weakest position of the anti-theft lock cylinder, and accordingly the purpose of anti-breaking of the anti-theft lock cylinder is achieved.
Description
Technical field
The utility model relates to a kind of anti-theft lock, refers to especially a kind of anti-cutting-off device of anti-theft lock.
Background technology
At present, the anti-theft door lock cylinder ubiquity is interrupted the safety problem of unlatching by violence nature; Because the restriction of the external form of anti-theft lock fixedly has a thumb wheel groove below the screw hole in the middle of anti-theft lock.Thereby fixedly the screw hole site has become the weakest place of anti-theft lock, and the theft personnel utilize violent tool anti-theft lock can be interrupted; Thereby by lock core anti-theft technique structure, anti-theft lock is not opened.
The utility model content
The utility model proposes a kind of anti-cutting-off device of anti-theft lock, solved in the prior art anti-theft lock easily by the shortcoming of violence damage.
The technical solution of the utility model is achieved in that
A kind of anti-cutting-off device of anti-theft lock, described anti-theft lock is provided with thumb wheel, and this thumb wheel below is provided with fixed screw holes, it is characterized in that, is provided with the U-shaped anti-section bar that interrupts in described anti-theft lock bottom.
Described anti-theft lock bottom sides is provided with several through holes.
The described U-shaped anti-section bar side of interrupting is provided with perforation corresponding to several through holes of anti-theft lock bottom sides.
The described U-shaped anti-section bar side of interrupting is provided with the rectangular recess that the thumb wheel for anti-theft lock rotates.
The described U-shaped anti-section bar side of interrupting is provided with screw hole corresponding to the thumb wheel below fixed screw holes of anti-theft lock.
Describedly U-shapedly anti-interrupt that section bar penetrates perforation by rivet or screw and through hole is fixed on the anti-theft lock bottom.
Compared with prior art, the utility model has the advantage of, structure is relatively simple, and makes the U-shaped anti-section bar that interrupts by high tensile metal and protect the weakest place of anti-theft lock, thereby arrives the anti-purpose that interrupts of anti-theft lock.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the explosive view of the anti-cutting-off device of a kind of anti-theft lock of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of anti-cutting-off device of anti-theft lock, described anti-theft lock 1 is provided with thumb wheel 5, and these thumb wheel 5 belows are provided with fixed screw holes 9, are provided with the U-shaped anti-section bar 2 that interrupts that shape is complementary in described anti-theft lock 1 bottom.Described anti-theft lock 1 bottom sides is provided with through hole 3.Described U-shaped anti-section bar 2 sides of interrupting are provided with perforation 4 corresponding to anti-theft lock 1 bottom sides through hole 3.Described U-shaped anti-section bar 2 sides of interrupting are provided with the rectangular recess 6 that the thumb wheel 5 for anti-theft lock 1 rotates.Described U-shaped anti-section bar 2 sides of interrupting are provided with screw hole 8 corresponding to the thumb wheel 5 below fixed screw holes 9 of anti-theft lock 1.Describedly U-shapedly anti-interrupt section bar 2 and be fixed on anti-theft lock 1 bottom by rivet 7 or screw.
In simple terms, be exactly the anti-cutting-off device of a kind of anti-theft lock, adopt with the U-shaped anti-middle fixedly screw hole of section bar 2 protection lock cores of interrupting; U-shapedly anti-interrupt section bar and can adopt high duty metal to make, high duty metal is processed into the anti-section bar that interrupts of " U " type as shown in Figure 1, and wherein two sides are provided with three manholes or fixing screw hole, fixedly are being provided with rectangular recess below the screw hole; The anti-theft lock side of specific copper sheathing external form has and anti-three corresponding round through holes of section bar or the fixing screw hole of interrupting of " U " type.
Wherein " U " type prevents interrupting the copper sheathing bottom that section bar is installed in the anti-theft lock of specific copper sheathing sheet type; The external form of copper sheathing bottom interrupts matching of section bar with " U " type is anti-, and " U " type is anti-interrupts on section bar and the specific copper sheathing external form lock core copper sheathing round through hole and fixedly the screw hole is just in time corresponding.Can be fixed together by rivet or screw.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
