The domes of the utility model key just can enter corresponding key channel smoothly once inserting the back, and the material of key employing comprises rubber-like material and rubber-like metal material material not.

Arch key of the present utility model also makes the thief be difficult to it is copied, and mutual opening rate is extremely low, and safety is very high.

Be provided with lock core marble hole as above-mentioned lock core along the top of key approach axis, lock core marble hole communicates with key channel, be provided with lock core marble in the lock core marble hole, the lock housing position corresponding with lock core marble hole is provided with lock housing pellet shot from a slingshot hole, lock housing pellet shot from a slingshot hole from outside toward interior marble spring and the lock housing pellet shot from a slingshot of being provided with successively, the part of lock housing pellet shot from a slingshot can enter in the lock core marble hole.

Surface as above-mentioned lock core has the arc stopper slot, is provided with lock pin and pin-and-hole in the lock housing, and an end of lock pin is fixed in the pin-and-hole, and the other end of lock pin stretches in the arc stopper slot.

Slide in the arc stopper slot as above-mentioned lock pin, and drive lock core and back and forth rotate, rotation angle range is 0 °-180 °.

Be the hollow-core construction of upper opening as above-mentioned lock housing pellet shot from a slingshot, an end of marble spring can enter in the opening of lock housing pellet shot from a slingshot.

Be provided with for fixing sealing up a door of marble spring as above-mentioned lock housing.

Be provided with the bellmouth corresponding with lock core marble hole on the key as above-mentioned.

Be provided with inclined-plane for the jack-up lock core marble as the insertion end of above-mentioned key.

The left and right sides as above-mentioned key also is provided with tartar.

The left and right sides at key arranges tartar, mainly in order to confuse the thief, increases the difficulty that key copies.
