Abstract
The utility model relates to a drilling-prevention closer for a keyhole. The utility model is composed of a closer movable core, a lock core, a closer ball, a closer sleeve, a closer sleeve ball, a closer sleeve spring, a chock plug, a buckled spring, and a key. The utility model is characterized in that the point of an outer opening of the closer movable core is provided with a circular sheet-shaped movable ring, the middle part of the peripheral thickness of the movable ring is provided with a steel ball groove, and the opening of the key is arranged in the diameter of the movable ring. The movable ring is fastened by three sets of steel balls which are arranged in the closer sleeve, a spring and the chock plug. On the basis of the original ball closer, the utility model is additionally provided with a protective movable sheet which is closed at the outer part of the lock core, which causes the utility model not to be drilled by an electric hand drill or a hand drill at the point of the opening of the key when closing, and causes the lock core to have the abilities of drilling prevention and damage prevention. The utility model is suitable for any ball type closer.
Description
The utility model belongs to the pin tumbler lock parts, particularly has the locking of anti-drilling function.
Existing pellet shot from a slingshot locking, generally draw together core, lock core, pellet shot from a slingshot, locking cover, locking cover pellet shot from a slingshot, locking sleeve spring, chock plug, buckle spring and key is formed by locking, the lock cylinder mouth promptly is the key mouth, there are not any safeguard procedures, lock core is pierced with Electric portable drill or hand drill by the robber easily, pellet shot from a slingshot is come off, pellet shot from a slingshot is taken out, lose the locking function, anti-destructive power extreme difference.
The purpose of this utility model is to design a kind of novel anti-drilling locking, on the basis of former pellet shot from a slingshot locking; set up the protection activity template that is enclosed in the lock core outside; make it behind locking, use Electric portable drill or hand drill to pierce at key mouth place, make locking have anti-drilling damage capability.
Anti-drilling locking of the present utility model, by the locking slide core, lock core, the locking pellet shot from a slingshot, the locking cover, locking cover pellet shot from a slingshot, the locking sleeve spring, chock plug, the button spring, key is formed, it is characterized in that: the place is provided with a disc active ring at locking slide core collar extension, circle Zhou Houdu middle part is provided with steel bead groove, having the cross key in the diameter of circle imports and exports, active ring is by three groups of steel balls that are arranged in the locking cover, spring and chock plug are fastening, it is outside to fix on the locking cover, equal with locking core collar extension, active ring can not be pressed into, can not deviate from, play sealing lock core port and anti-drilling effect when active ring revolves.
Import and export and to be designed to circle or in-line according to instructions for use at the key at disc active ring middle part.
Anti-drilling locking production method of the present utility model is identical with common locking principle, and former locking slide core collar extension is partly shortened, and sets up the anti-drilling active ring of a slice at the collar extension place of locking slide core, is installed in the collar extension of locking slide core.When using Electric portable drill or hand drill to bore tapered end locking core in the key mouth, be enclosed in anti-drilling active ring that locking draws together the core collar extension along with electric drill or hand drill with the speed running, make drill bit can't pierce anti-drilling active ring half point in the least; If the robber wants anti-drilling active ring is prized, three directions, the three place's steel balls that are connected mutually in being connected active ring and locking overlapping block steel disc, steel ball is withstood by the chock plug on spring and top, spring tension is supported steel ball tightly to withstand in the active ring camber pearl groove, making it active ring can only change at the locking mouth, can't prize also and can't be pressed into.
The anti-drilling active ring of this locking adopts the processing of 45# carbon steel material, makes with extra care through heat treatment chromium plating to form, and the tapered end with locking cover, steel ball, spring and the spring chock plug of locking are formed had both had anti-drilling function, can play the effect that the sealing locking is drawn together the core collar extension again.This lock core has: one, consumable material in addition not equates with common locking raw material; Two, can play the key mouth sealing process of locking slide core; Three, play anti-drilling, tamper-resistant function; Four, sturdy and durable, easy to use.Be applicable to any pellet shot from a slingshot class locking.
Below in conjunction with drawings and Examples anti-drilling locking is described further.
Fig. 1 is the structure chart of anti-drilling locking
Fig. 2 is the A-A sectional drawing of Fig. 1
Fig. 3 is the profile of anti-drilling active ring
Fig. 4 is that anti-drilling active ring key mouth is circular profile
