Utility model content
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provides a kind of simple in structure, and cost of production is low, a kind of door latch structure with the anti-drilling function of anti-cutter of good anti-theft effect.
The utility model object realizes with the following methods: a kind of door latch structure with the anti-drilling function of anti-cutter, and it comprises lock body, lock core, panel, protective cover, protective sheet, is characterized in that: the tail end of described protective sheet is provided with positive stop lug boss, be installed in rotation in the shoulder hole in protective cover, protective sheet is provided with protective jacket at the tail end of protective cover after installing, and protective jacket snare is in lock core periphery, and be welded and fixed with protective cover, protective cover is limited in the endoporus of protective sheet.
Described protective jacket is opening bearing shell shape, is arranged in the resettlement groove of protective cover endoporus the limiting card platform of protective jacket both ends open holding on resettlement groove.
Described protective jacket and protective cover are that welding metal material is made.
After described protective jacket is installed, its tail end is mutually concordant with the rear end face of protective cover.
Described shoulder hole has three grades, and the limited step of protective sheet tail end is pressed on first order step, and the front end of protective jacket is pressed on the step of the second level, and the tail end of protective sheet is mutually concordant with third level step, and pad is located between protective jacket tail end and third level step.
Anti-drilling sheet is also installed between described protective jacket and protective sheet.
Described anti-drilling sheet is made by high rigidity manganese steel material.
The base of described protective cover is up-small and down-big trapezoidal shape.
The beneficial effects of the utility model are: 1) simple in structure, cost of production is low, improve the market competitiveness.2) at copper lock core, be outside equipped with protective sheet, and the tail end of protective sheet is pressed on protective jacket, because protective jacket and protective cover are welded and fixed, so when external force cutter hits protective sheet, the cutter power of hitting is turned is added to protective cover, avoids lock core stressed and destroyed.3) be further to strengthen anti-theft capability, in the utility model, the anti-drilling sheet of being made by high rigidity manganese steel be also installed between protective jacket and protective sheet, avoid lock core to be destroyed by instruments such as electric drills.
Accompanying drawing explanation
Fig. 1 is the utility model general assembly design sketch.
Fig. 2,3,4 is lock core and protective cover assembling drawing in the utility model.
Fig. 5 is protecting cover structure sectional view in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made to concrete further instruction.Have a door latch structure for the anti-drilling function of anti-cutter, it comprises lock body 1, lock core 2, panel 3, protective cover 4, protective sheet 5, is characterized in that: the tail end of described protective sheet 5 is provided with positive stop lug boss 51, be installed in rotation in the interior shoulder hole 41 of protective cover 4, protective sheet 5 is provided with protective jacket 6 at the tail end of protective cover 4 after installing, and protective jacket snare is in lock core 2 peripheries, and be welded and fixed with protective cover 4, protective cover 4 is limited in the endoporus of protective sheet 5.
Described protective jacket 6 is opening bearing shell shape, is arranged in the resettlement groove 42 of protective cover 4 endoporus the limiting card platform 43 of protective jacket 6 both ends open holdings on resettlement groove.
Described protective jacket 6 and protective cover 4 are that welding metal material is made.
After described protective jacket 6 is installed, its tail end is mutually concordant with the rear end face of protective cover 4.
Described shoulder hole 41 has three grades, the limited step 51 of protective sheet 5 tail ends is pressed on first order step 411, the front end of protective sheet 5 is pressed on second level step 412, the tail end of protective sheet 5 is mutually concordant with third level step 413, and pad 414 is located between protective jacket tail end and third level step 413.
