Abstract
The utility model discloses a helical lock, comprising a lock body and a lock bladder arranged in the lock body, which is characterized in that the lock bladder is provided with a helical keyhole inside, hoodle holes having a spiral arrangement are positioned on the lock bladder and communicated with the bottom of the helical keyhole, the lock body is provided with micropyle which corresponds to the hoodle holes. The utility model also discloses a key matched to the helical lock, which is provided with a helical tooth matched to the helical keyhole on the shank. The helical lock of the utility model has a slide-proof and a vibration-proof effect,thereby improving safety and secrecy performance.
Description
Technical field
The utility model relates to a kind of cylinder lock and key thereof.
Background technology
Making a general survey of all in the market locksets, no matter be the high-tech product of collection sound, light, mechanical, electrical one, still is prevailing lock, and what its utilization rate was high, the most universal still is based on the mechanical lock of cylinder lock.And the lock keyhole of cylinder lock both domestic and external and key bit with matching, groove structure are single, and by stirring or vibrating technical methods such as pellet shot from a slingshot and unblank, therefore, the safety and the theftproof performance of these locksets are not ideal enough easily.
Summary of the invention
First purpose of the present utility model be to provide a kind of and can reach anti-and dial, the spiral lock of vibrationproof, safety.
Another purpose of the present utility model is to provide a kind of and above-mentioned spiral the phase-locked key that cooperates.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of spiral lock, comprise lock body and be installed in the interior lock gall of lock body, it is characterized in that being provided with in the described lock gall spiral keyhole, described lock gall is provided with the hoodle hole of shape arrangement in the shape of a spiral, the hoodle hole communicates with the bottom of spiral keyhole, and described lock body is provided with and the corresponding hole of bead, hoodle hole.
Preferred embodiment a kind of as the utility model, the spiral angle of described spiral keyhole is preferably 180 °.
As the improvement of the above-mentioned embodiment of the utility model, on the described lock body big envelope is installed.
The phase-locked key that cooperates of a kind of and above-mentioned spiral provided by the utility model comprises the shank of the key, it is characterized in that being equipped with on the described the shank of the key helical form tooth portion that matches with the spiral keyhole.
As the above-mentioned key of the utility model preferred embodiment, the spiral angle of described helical form tooth portion is preferably 180 °.
As the improvement of the above-mentioned embodiment of the utility model, described the shank of the key is provided with and is provided with circular hole, and axle is installed in the circular hole, in the described helical form tooth portion shaft coupling is installed, and described helical form tooth portion connects with the shank of the key by shaft coupling and axle.
The beneficial effects of the utility model are: the keyhole of spiral of the present utility model lock is shape in the shape of a spiral, therefore, its have anti-ly dial, the effect of vibrationproof, thereby increased the security performance of lock; Also be provided with circular hole on the shank of the key of key, axle is installed in the circular hole, helical form tooth portion connects with the shank of the key by the shaft coupling that is installed on the axle, like this, can 360 ° between the shank of the key and the helical tooth portion rotate freely, therefore inserting in the process of key to keyhole, promote the shank of the key, the rotation of helical form tooth portion screws in the keyhole helical form tooth portion, thereby reaches the purpose of unblanking.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model perspective exploded view.
The specific embodiment
With reference to Fig. 1, a kind of spiral lock disclosed in the utility model comprises lock body 1, big envelope 6 is installed on the lock body 1, lock gall 2 is installed in lock body 1, an end of lock gall 2 can be installed sword iron 12, be provided with spiral keyhole 3 in lock gall 2, the spiral angle of spiral keyhole 3 preferably is set to 180 °.
As shown in the figure, for cooperating the unlatching of above-mentioned spiral lock, the utility model discloses a kind of key, this key case spatula handle 7, the shank of the key 7 can adopt the moulding of hollow out flower shape, so that it is elegant in appearance.The helical form tooth portion 8 that matches with spiral keyhole 3 is installed on the shank of the key 7, when the spiral angle of spiral keyhole 3 is 180 °, the spiral angle of helical form tooth portion 8 also correspondingly is set to 180 °, because keyhole of the present utility model is shape in the shape of a spiral, its pellet shot from a slingshot is difficult for being stirred by foreign matter and vibrating, thereby can reach anti-and dial, the effect of vibrationproof, thereby increased the security performance of lock.
The shank of the key 7 is provided with circular hole 9, and axle 10 is installed in the circular hole 9; In helical form tooth portion 8 shaft coupling 11 is installed, helical form tooth portion 8 connects with the shank of the key 7 by shaft coupling 11 and axle 10, like this, between the shank of the key and the helical tooth portion rotatable 180 °, therefore, promote the shank of the key inserting in the process of key to keyhole, helical form tooth portion rotation, when Rotate 180 °, helical form tooth portion screws in the keyhole, at this moment relative fixed between the shank of the key and the helical tooth portion, be connected as a single entity, rotate the shank of the key again, rotate lock gall, can drive sword iron, reach the purpose of unblanking.
The above only is a preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it.So long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
