Abstract
Lock with inside lock, it relates to a kind of lockset, has solved the problem of the poor stability of opening different locks with different keys.The tapered end of described main lock is designed to mushroom-shaped, with the main lock secondary lock that has been coaxially set, the tapered end of secondary lock is designed to hemispherical, and the end by ratchet on two dwangs is provided with an extension spring that connects two dwangs, and the other end of two dwangs is corresponding with the tapered end of secondary lock.The present invention has only and possesses this two keys simultaneously, could normally use this novel Lock with inside lock, increases safety, and protective capacities improves greatly.Can be used for various doors, warehouse, safety cabinet.
Description
Technical field
The present invention relates to a kind of novel protection tool, particularly relate to a kind of lockset that increases safety.
Background technology
Common lock is all opened different locks with different keys, if this key is lost, is perhaps only grasped by a certain people, and safety and protective just greatly reduce so.
Summary of the invention
In order to solve the problem of the poor stability that above-mentioned prior art exists, the purpose of this invention is to provide a kind of Lock with inside lock, by on existing lockset, increasing a secondary lock, can increase safety, protective capacities improves greatly.
Technical scheme of the present invention is, this Lock with inside lock, comprise a main lock, it is characterized in that, the tapered end of described main lock is designed to mushroom-shaped, with the main lock secondary lock that has been coaxially set, the tapered end of secondary lock is designed to hemispherical, two dwangs are hinged by gyroaxis, each dwang end of homonymy at gyroaxis is provided with an aduncate ratchet, described ratchet cooperates with the tapered end of main lock, and the end by ratchet on two dwangs is provided with an extension spring that connects two dwangs, and the other end of two dwangs is corresponding with the tapered end of secondary lock.
At gyroaxis door installed inside one manual knob, this manual knob is provided with a pair of shifting block that cooperates with two dwangs.Manual knob rotates can open ratchet, so that needn't use the key of secondary lock just can open ratchet easily.
When main locking, if the tapered end of secondary lock is in the state of stretching out, then ratchet opens, and secondary lock is inoperative, main lock and common the same use of lock; If the tapered end of secondary lock is in retracted state, jaws close then, the mushroom tapered end of main lock is pinned by ratchet stop, can't open main lock, has only with the key open auxiliary lock of secondary lock and just can open main the lock.Main lock is locked each with a key with secondary, has only like this and possesses this two keys simultaneously, could normally use this novel Lock with inside lock.
The invention has the beneficial effects as follows that two keys drive a lock, increase safety, protective capacities improves greatly.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation when the tapered end of secondary lock is in retracted state.
Among the figure, 1. main lock, 2. main lock, 3. ratchet, 4. secondary lock, 5. secondary lock, 6. gyroaxis, 7. extension spring.
Fig. 2 is that the tapered end when secondary lock is in the structural representation when stretching out state.
The specific embodiment
As shown in Figure 1, this Lock with inside lock, comprise a main lock 1, a tapered end of described main lock 1 is designed to mushroom-shaped master lock 2, with the main phase-locked standing part that cooperates in be provided with secondary lock 4, secondary lock 4 tapered ends are designed to hemispherical secondary lock 5, also be provided with a pair of two dwangs of energy wraparound rotating shaft 6 foldings in addition, one end of two dwangs is provided with the ratchet 3 that a pair of and main lock cooperates, it is corresponding with the secondary tapered end of locking to be provided with the other end of 7, two dwangs of extension spring that connect two dwangs by an end of ratchet on two dwangs.
Ratchet 3 is used for the main lock 2 of stop mushroom-shaped, and this folding to ratchet 3 resets with an extension spring 7 controls.At gyroaxis door installed inside one manual knob, this manual knob is provided with a pair of shifting block that cooperates with two dwangs.Manual knob rotates can open ratchet, so that needn't use the key of secondary lock just can open ratchet 3 easily.
When main lock 1 was locked, if secondary lock 5 is in the state of stretching out, then ratchet 3 opened, and pair lock 4 is inoperative, main lock 1 and common the same use of lock; If the tapered end 5 of secondary lock 4 is in retracted state, ratchet 3 closures then, mushroom main lock 2 is pinned by ratchet 3 stop, can't open main lock 1, has only just can open with the key open auxiliary lock 4 of secondary lock 4 and mainly locks 1.Master's lock 1 locks 4 respectively with a key with secondary, has only like this and possesses this two keys simultaneously, could normally use this novel Lock with inside lock.
