Description
Technical field
The utility model relates to a kind of tapered end protective device, relates to lock field.
Background technology
The lock-protector that existing large area is used is ultra-thin materials and adds plastics formation, very simple and crude after installation, as long as there is simple tool just can destroy very easily it, then rapid damage tapered end is realized and being unblanked, and it is poor to the protective effect of tapered end.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned shortcoming existing for existing tapered end, and providing a kind of can significant effective improve the tapered end protective device of protecting tapered end ability.
The utility model solves the problems of the technologies described above adopted technical scheme:
A kind of tapered end protective device, include and be arranged on the front assembly in shop front outside and be arranged on the tergolateral interior lock protection cover of door, described front assembly includes tapered end inner core, interior core cover plate, anti-drilling sheet, anti-drilling board, cushion cover and inner core base plate, described tapered end inner core is inserted in described interior core cover plate, described anti-drilling sheet and anti-drilling board are arranged in tapered end inner core by cushion cover, described anti-drilling sheet has the through hole with the lockhole form fit of described tapered end inner core, described inner core backplane, in the outside of cushion cover, is connected with interior core cover plate by the first screw; Between described front assembly and shop front outside, be provided with pad, the inner side of the shop front is provided with front shoe, on described inner core base plate and interior core cover plate, be also provided with the second screw hole, by the second screw, connect, on described front shoe, have the screwed hole mating with described the second screw, the second screw, through pad and the shop front, is fixed on front assembly in the shop front; Described tapered end inner core is provided with the double-screw bolt that runs through the described shop front, and described door back of the body inner side is provided with rear fixed plate, and on described rear fixed plate, corresponding described double-screw bolt position is provided with rear hold-down screw, and described rear hold-down screw coordinates location with described double-screw bolt; Described interior lock protection cover is connected by the 3rd screw with described rear fixed plate.
Screwed hole on described front shoe is two, is arranged in upper and lower two ends.
The double-screw bolt of described tapered end inner core is two, is arranged in the left and right sides in stage casing.
Described tapered end inner core is provided with boss device, and described anti-drilling sheet is provided with the protruding hanging platform that coordinates location with described boss device.
Compared with prior art, the utlity model has following beneficial effect: 1, anti-drilling sheet is the anti-drilling steel plate of thickening type, and be delocalization idling conditions, can keep out the attack of Electric drill-bit to tapered end inner core position completely; 2, tapered end inner core is also furnished with the anti-drilling board of a stiffened just above, to drill bit, the attack of hoodle is not stayed to chance; 3, the as a whole structure of front assembly and the shop front, reaches pick-proof effect; 4, on tapered end inner core, there are two double-screw bolts that stretch into completely in door-plate can prevent the situation of tearing screw open after door plate deformation; 5, fixed form adopts inside and outside twocouese bolt structure, and Anti-dismounting structure is more stable; 6, in installation process without dismounting lock body, reduced greatly work difficulty and working time, can realize user and install voluntarily; 7, this device is full steel structure, and integral body can be born the requirement of higher temperature.
