Abstract
The invention provides a lock head of a spring lock. The lock head comprises a lock shell and a lock core; an external latch hole is formed on the lock shell; a spring and an external latch are arranged in the external latch hole; a key hole and an internal latch hole vertical to each other are arranged on the lock core; the internal latch hole is adjacent to the key hole and is communicated with the key hole; the aperture of at one end of the internal latch hole close to the key hole is smaller than the aperture of the end away from the key hole; the big aperture section is filled with the internal latches matched with the size of the big aperture; the tail end of the external latch is extended in the latch hole at the initial state. According to the lock head and the matched key provided by the invention, the internal latches are hidden out of the key hole, so that the latches can not be seen on the key hole; when a key is inserted in the key hole, the latches are hidden, an unlock tool cannot dial the latches, the difficulty of technical unlocking is greatly increased, therefore, the burglar-proof function is improved.
Description
(1) technical field
The present invention relates to a kind of lock, concrete is a kind of cylinder lock, is applicable to products such as security door, interior door, safety cabinet, automobile and motorcycle.
(2) background technology
Chang Yong cylinder lock head in the market, wherein lock core mainly contains two kinds: a kind of is towards the teeth key lock core, another kind is the mill teeth key cylinder, principle all is identical, distribution one row or the short pellet shot from a slingshot that differs of two platoon leaders in key channel (keyhole), after key inserted lock core, pellet shot from a slingshot and key tooth flower coincide, lock core just can rotate, and lock just can be opened.Various lock cores on the market, although the key grooved differs, marble amount is different with shape, but any is arranged is identical, that be exactly pellet shot from a slingshot all be to be arranged on the key channel, any unlocking tool that can insert keyhole can both be stirred pellet shot from a slingshot, this has just buried hidden danger for technology unlocking.
(3) summary of the invention
In order to overcome existing cylinder of spring lock above shortcomings, the invention provides the key of a kind of cylinder lock head and cooperation thereof, by the pellet shot from a slingshot in the lock core is hidden design, improved theftproof performance.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cylinder lock head, include lock housing and lock core, described lock housing is provided with outer pellet shot from a slingshot hole, described outer pellet shot from a slingshot hole is built-in with spring and outer pellet shot from a slingshot, described lock core is provided with keyhole and the interior pellet shot from a slingshot hole of orthogonal layout, the adjacent keyhole in pellet shot from a slingshot hole is arranged also and is communicated with it in described, the aperture of close keyhole one end in pellet shot from a slingshot hole is less than the aperture away from keyhole one end in described, described large aperture section is filled with big or small adaptive interior pellet shot from a slingshot with it, original state, the end of described outer pellet shot from a slingshot extend to interior pellet shot from a slingshot hole.
Be provided with positioning bead in the described lock core, described lock housing correspondence is provided with groove, original state, and in the built-in groove of described positioning bead part, described lock core is located by positioning bead and the embedding of groove phase with lock housing.
The present invention needs a key that matches with the present invention in use, and described key includes key bar and the shank of the key, and described key bar includes stator and the activity template that is arranged in parallel, and described stator is two, connects by guide peg; Described activity template is arranged between two stators, described guide peg run through described activity template and with it oblique arrange pellet shot from a slingshot hole and the tartar that offsets and cooperate with the pellet shot from a slingshot of large aperture section in described activity template one side is provided with and can inserts; Described activity template is provided with the impingement angle that can offset and cooperate with the lock core end face, and described impingement angle extends to the stator outside; Described activity template is shorter than stator, and the afterbody of adjacent the shank of the key one end of described activity template is provided with back-moving spring, and the other end of described back-moving spring is connected with stator; Described stator is provided with the step that can offset and cooperate with the lock core end face, and described step just satisfies the tartar of activity template and the requirement that interior pellet shot from a slingshot offsets and cooperates with the range distance of impingement angle.
Offer the locating hole that cooperates with positioning bead on the described stator.
Described guide peg is vertical with stator affixed, and described activity template is provided with the skewed slot for the guide peg slippage.
Described guide peg and stator oblique are affixed, and described activity template is provided with the through hole that runs through for guide peg.
Operating principle of the present invention is: key bar is made up of stator and activity template two parts, stator and lead are fixed together, form a space, the activity template of middle a slice band tartar is through on the lead, the activity template of band tartar can be done track around lead and move, key is not when using, and back-moving spring is shifted activity template onto bottom, and activity template is hidden in the stator; In the process that key insertion lock core is unblanked, insert lock core, impingement angle on the activity template at first offsets with the lock core end face, impingement angle on the activity template can tangle the lock core outside, this moment, activity template came to a halt, stator can continue to advance with whole key, because guide peg advances synchronously with stator, make sky be enclosed within activity template on the guide peg along the guide peg lifting, interior pellet shot from a slingshot was withstood in the pellet shot from a slingshot hole in tartar on the activity template moved to, rotate key this moment, and the positioning bead on the lock core falls in the locating hole on the stator, can unblank; Unblanking to finish is rotated in place, and key can eject stealthy lock core automatically.
Beneficial effect of the present invention mainly shows: 1, interior pellet shot from a slingshot is hidden in outside the keyhole, make and cannot see pellet shot from a slingshot on the keyhole fully, key inserts keyhole does not have pellet shot from a slingshot, and unlocking tool is just dialled less than pellet shot from a slingshot, the difficulty of technology unlocking will increase greatly, has improved anti-theft feature; 2, between lock core and lock housing, add the embedding structure mutually of positioning bead and groove, had only the locating hole that enters on the key when positioning bead disengaging groove just can unblank, improved security performance; In like manner, key has only and rotates to correspondence position, could eject key, and practicality is stronger; 3, simple in structure, result of use good.
