Abstract
The utility model relates to an anti-drilling device for a safe which improves the safety performance aspect of an anti-theft safe. The utility model is composed of a steel ball box which is full of steel balls. The anti-drilling device is arranged in an interlayer which is arranged between the inner box board and the outer box board of the safe of the key part to affect the open of the safe. When a theft dills the outer box board and the steel ball box of the safe by a portable power tool to go on drilling the safe, as the free rotation of the steel balls in the steel ball box, the drill is prevented from advancing, causing the theft can not to drill the key part of the open of the safe, and thereby, the safety performance of the safe is enhanced.
Description
The utility model relates to the anti-boring device of a kind of safety cabinet that improves theft proof strongbox security performance aspect.
Though present theft proof strongbox adopts thicker steel plate to increase its barrier propterty; but still anti-incessantly robber drills the cabinet of safety cabinet with electric drill, electric hammer; pry open the latch mechanism of safety cabinet then, open safety cabinet, make safety cabinet lose the effect of protection property.
Task of the present utility model is the anti-boring device of a kind of safety cabinet simple in structure, that cost is low, easily manufactured of design.
With accompanying drawing the technical solution of the utility model is described below.
Accompanying drawing is the anti-boring device sectional view of a kind of safety cabinet.
The mark sequence number is expressed as follows respectively in the accompanying drawing: 1, steel ball; 2, steel ball box; 3, safety cabinet cabinet boxboard outdoors; 4, fire cement; 5, boxboard in the safety cabinet cabinet door; 6, locking bolt.
Fill in the steel ball box 2 in the accompanying drawings can Free steel ball 1, form the utility model Anti-drilling device. The quantity of the size of steel ball box 2 and shape and steel ball 1 and size, optionally anti-Protect the scope of probing and decide, steel ball box 2 assemble weldings the need protection can the opening safety cabinet lock On near the interior boxboard 5 of the safety cabinet cabinet door bolt 6, by boxboard 5 and safety cabinet cabinet in the safety cabinet cabinet door Filling refractory cement 4 in the safety cabinet cabinet door that forms of boxboard 3 outdoors, anti-drilling merit of the present utility model Can be to show like this, when the robber attempts to drill outdoors boxboard 3 of safety cabinet cabinet with electric drill or electric hammer With boxboard 5 in the safety cabinet cabinet, when attempting the locking bolt 6 of energy of rupture opening safety cabinet cabinet door, because steel Ball box 2 device is in the corresponding safety cabinet cabinet door of locking bolt 6 on the boxboard 5, when electric drill or electric hammer Drill bit is drilling the safety cabinet cabinet outdoors when boxboard 3 and steel ball box 2, because the Free-rolling of steel ball 1, Drill bit can't be continued to the probing of safety cabinet the inside, thereby protected locking bolt 6, safety cabinet is got With safeguard protection.
Advantage of the present utility model is simple in structure, and is easy to install, low cost of manufacture.
Accompanying drawing is an embodiment of the present utility model: the diameter that is employing is that 7 of the steel balls of Φ=20mm are placed on internal diameter Φ=62mm; interior height is in the garden shape steel ball box of 21mm; steel ball can freely rotate in the steel ball box; the chuck of portable power tool is usually between 7～16mm; like this when using diameter as Φ=16mm bit drills steel ball box; though the steel ball box is drilled; Φ=20mm steel ball can not come off in the hole yet; make steel ball continue to play anti-drilling effect; because freely rotating of steel ball; stop drill bit to be drilled forward, made drill bit can't get into locking bolt, protected the safety of safety cabinet.
