Detailed description of the preferred embodiments
As shown in fig. 1 to 5, an anti-theft secured lock cylinder structure includes an outer housing 3, a lock cylinder 2, and a tongue 4, wherein:
the lock core 2 and the lock core shaft are arranged in the outer shell. The key hole 15 is positioned in the lock core parallel to the axis of the lock core, and the front end port of the key hole is arranged on the front end surface of the lock core for inserting the key 1. The upper end in the lock core of the key hole section is provided with a plurality of tongue piece slotted holes 12 vertical to the key hole. The upper port of each tongue piece slotted hole is positioned on the corresponding peripheral wall of the lock core, and the lower port of each tongue piece slotted hole is communicated with the key hole of the corresponding part. The two sides of the upper end of the key hole 15 and the lock core parallel to the axis of the lock core are respectively provided with a transmission sheet groove and a pressing sheet groove. The transmission sheet groove and the pressing sheet groove are communicated with each tongue piece groove hole of the corresponding part. The convex body groove 10 is arranged on the outer shell from the upper end in the lock core which is positioned at the rear end of the key hole and is vertical to the key hole to the corresponding part. One end of the pressing sheet groove is communicated with the convex body groove at the corresponding side. One end of the driving sheet groove is communicated with the convex body groove on the corresponding side and is continuously extended and communicated with the rear end surface of the lock cylinder, namely, the rear end of the driving sheet groove is communicated with the convex body groove on the corresponding side and passes through the convex body groove on the corresponding side to be continuously extended and communicated with the rear end surface of the lock cylinder.
The tongue pieces are respectively positioned in the tongue piece slotted holes 12, and the side edge of the tongue piece corresponding to the transmission piece is provided with a release groove 21. The lower end of the tongue piece is positioned in the keyhole, and the upper end of the tongue piece is propped against the inner shell of the outer shell through a tongue piece spring 13.
And the transmission piece 7 is positioned in the transmission piece groove. And a transmission clamping groove 20 is arranged on the transmission sheet at the side corresponding to the release groove 21 of the tongue piece. The rear part of the driving sheet is provided with an open groove, a driving sheet spring 9 and a buffer block 16 are arranged between the inside of the open groove and the rear end of the sliding lug 6 of the corresponding part, and the rear end of the driving sheet can extend out of the rear end face of the lock cylinder to be connected with the lock opening structure.
And the pressing sheet 5 presses the tongues under the action of the rotating lock core and the sliding convex body so as to prevent the technical unlocking from shifting the tongues and prevent burglary. The pressing sheet is positioned in the pressing sheet groove, and a pressing clamping groove 22 is arranged on the pressing sheet on the side corresponding to the tongue piece.
And the sliding convex body 6 is positioned in the convex body groove. A convex body spring 11 is arranged between the lower end of the sliding convex body and the inner lower end of the convex body groove. The two axial sides of the sliding convex body part positioned in the convex body groove of the outer shell part are bevel edges 19, namely the two axial sides of the upper end of the sliding convex body at the position parallel to the lower end surface of the outer shell are bevel edges; the part of the sliding convex body positioned in the convex body groove corresponding to the outer shell body can also be in a semicircular shape. The front end surface of the sliding convex body at the side corresponding to the pressing sheet is a pressing inclined surface 18. The rear end surface of the sliding convex body at the side corresponding to the buffer block is a transmission inclined surface 17. The sliding boss portion with the beveled edge 19 is located in the boss groove of the outer housing portion.
The semi-circular radius of the sliding convex body is the same as the thickness of the outer shell. After the pressing inclined surface of the sliding convex body contacts the pressing sheet, the transmission inclined surface of the sliding convex body contacts the buffer block. The number of the tongues is 4-20. The rear end of the pressing sheet groove is communicated with the convex body groove on the corresponding side, and the pressing sheet groove is communicated with each tongue piece groove hole of the corresponding part. One end of the driving sheet groove is communicated with the convex body groove on the corresponding side and continues to extend and communicate with the rear end face of the lock core, and the driving sheet groove is communicated with each tongue piece groove hole of the corresponding part.
The lock opening structure and the like of the invention are the same as the traditional structure, so the description is not repeated.
When in use, the structure of the invention is that a sliding convex body, a pressing sheet and a driving sheet which rotate along with the lock core are added on the rotatable lock core. The bevel edge (or the semicircular part) at the upper part of the sliding convex body is arranged in the convex body groove of the outer shell at the upper part of the lock core, namely, the part of the sliding convex body with the bevel edge projection extends out of the circumference of the lock core and enters the space of the outer shell. As shown in fig. 2, it is obvious that when the lock core is rotated in that direction, the oblique sides of the sliding protrusions are pressed by the corresponding sides of the outer shell, and can move to the center of the lock core for a certain distance as shown in fig. 3 until the upper end faces of the sliding protrusions are all parallel to the circumferential wall of the lock core and rotate together with the lock core, that is, the upper end faces of the sliding protrusions all enter the protrusion grooves in the lock core.
When the sliding convex body moves towards the center of the lock core, the pressing sheet 5 is pushed firstly, and then the transmission sheet 7 is pushed. A plurality of tongues 4 (only 3 in the figure) arranged in the axial direction of the lock cylinder do not penetrate through the shell to form the rotation inhibition of the lock cylinder, but as shown in fig. 4 and 5, a release groove on each tongue is matched with a drive slot of the drive plate. When the tongue piece is under the action of the teeth 14 of the key 1, the transmission slots and the release slots form a straight line parallel to the axis of the lock cylinder, the transmission piece 7 is not clamped by the tongue piece, and the transmission piece can move along the straight transmission piece slot (namely, the buffer block 16 is pressed under the transmission inclined surface 17 of the sliding convex body and then presses the transmission spring 9, and the transmission spring presses the transmission piece again to extend to the tail part to the position of a dotted line 8 in fig. 1 (namely, the position of the lock opening structure). That is, when the teeth of the key (and thus the tongues) are in the correct position, the tongues will allow the driver blade to move towards the rear of the lock cylinder to extend into engagement with the lock opening structure.
In fig. 5, when the pressing piece 5 moves forward (in the direction of arrow N in the figure) along the axis of the lock cylinder under the pressing of the pressing inclined surface 18 of the sliding protrusion 6 (refer to fig. 1), the protruding portion of the pressing slot corresponding to the tongue piece 4 of the pressing piece can press each tongue piece 4 against the tongue piece slot, and the technical poking of the tongue piece can be prevented no matter whether the position of the tongue piece is correct or not.
Referring to fig. 1 and fig. 3, when the lock core is rotated, the bevel edge of the sliding convex body 6 is pressed by the outer shell 3, the sliding convex body moves inwards by a stroke at a small angle, the pressing inclined surface of the sliding convex body 6 at the beginning of the stroke presses the pressing sheet 5, the pressing sheet and the protruding part of the pressing slot corresponding to the tongue piece 4 can press each tongue piece 4 on the tongue piece slot hole and can not be shifted, the rotation is continued, and the sliding convex body presses the driving sheet 7 to move through the buffer block and the driving sheet spring. If the key 1 is correct, the teeth of the key make each tongue piece and the driver blade form the correct position, and when the lock core is rotated continuously, the driver blade can move in the direction of arrow S under the driving inclined surface of the sliding convex body, the buffer block 16 and the driving spring, and extend to the tail part to the position of the dotted line 8 in fig. 1, and the extending part will act on the lock opening structure when the rotation is continued, and the lock is opened.
At this point it is not possible for the tongues which have been compressed to be in the correct position if the key 1 is wrong or has something else. When the transmission clamping groove of the transmission piece and the releasing groove of each tongue piece are not in a straight line parallel to the axis of the lock cylinder, the transmission piece continuously rotates, the transmission piece is clamped and pushed by the tongue piece and cannot move, the transmission piece cannot move along the straight transmission piece groove, even if the buffer block 16 is pressed down by the transmission inclined plane 17 of the sliding convex body, the transmission spring 9 is extruded, but the transmission spring only contracts, cannot push the transmission piece to move out of the rear end face of the lock cylinder, cannot act on a lock opening structure, and the lock cylinder cannot be unlocked by continuously rotating.
In a word, the invention can effectively resist technical unlocking people, changes the traditional lock core structure, and has the advantages of simple structure, reasonable design, high anti-theft standard, good safety and good use effect.
