Detailed Description

The invention will be further explained with reference to the drawings.

Fig. 1 is a schematic front view showing the structure of the present invention, and when the structure of the present invention is combined with the schematic left-right views of fig. 2 and fig. 3, the present invention comprises a housing 1, a lock shaft 2, a lock cylinder 5, a clamping plate 6 and a key guide column 9; wherein, the center of the bottom surface of the shell 1 is provided with a lock shaft hole 3, one end of the lock shaft 2 is fixedly connected with the center of the bottom surface of the lock core 5, and the other end penetrates out of the lock shaft hole 3 and is used for controlling the opening/closing of the door. A circular groove-shaped key guide column 9 is arranged on one side of a central core hole 10 of the lock core 5, the bottom surface of the key guide column 9 is fixedly connected with the bottom surface of the lock core 5, and a positioning hole 7 is arranged on the bottom surface of the lock core 5 in the middle of the key guide column 9 and used for positioning when a key is inserted. A clamping plate 6 is also arranged in the lock core 5 as seen from a core hole 10 in the center of the lock core 5; the inner sides of the corresponding shells 1 at the left and right sides of the clamping plate 6 are respectively provided with a groove 4 which can be inserted into a clamping head 11 of the clamping plate 6 and a shell transition groove 8 which can be movably placed into a limit lug 14 of the clamping plate 6. The structure and function of the snap-in plate 6, the groove 4 and the shell transition groove 8 are shown in detail in figures 4-6 and the description thereof.

Fig. 4 is a front view schematically showing the lock cylinder 5 of fig. 1 with the housing removed, and together with fig. 5 and fig. 6 showing the rear view and the sectional view taken along the line a-a, the lock cylinder 5 is cylindrical and the center of the outer side of the bottom surface thereof is fixedly connected with the inner end of the lock shaft 2; the middle part of the front side surface is provided with a rectangular chuck groove 12, and the chucks 11 of each chuck plate 6 are inserted in a stacking way in a locking state; the rear side is also provided in the middle with a rectangular core transition slot 13 in which the stop lugs 14 of the respective catch plates 6 can pass in the chain and in the shell transition slot 8. The height of the core transition groove 13 is greater than that of the chuck groove 12.

Within the lock cylinder 5 are stacked

several card plates

6, 11 shown in the figure. The middle of the clamping plate 6 is provided with a through hole which can pass through a key, namely a clamping plate hole 15, one end of the outer side is provided with a limiting convex block 14, and the other end is provided with a clamping head 11 which can extend out of the lock core 5; an unlocking circular arc 16 correspondingly matched with the key tooth is arranged on the clamping plate on one side of the key through clamping plate hole 15, the key tooth pushes the unlocking circular arc 16 in the rotation process to enable the clamping plate 6 to transversely move in the lock cylinder, and the clamping head 11 is inserted into/separated from the groove 4. A return spring 17 is arranged between one end of each clamping plate 6 and the lock cylinder 5, so that the clamping heads 11 of the clamping plates 6 extend out of the clamping head grooves 12 of the lock cylinder 5 without being controlled by a key and are inserted into the grooves 4 of the shell 1, the shell 1 and the lock cylinder 5 cannot rotate mutually, and the lock is in a locked state.

Fig. 7 is a front view of the key, and together with the top view of the key shown in fig. 7, a key tooth holder 20 is provided on the upper end of the key shaft 19 of the key 18, and key teeth 21 corresponding to the unlocking arc 16 are provided on the key tooth holder 20.

The working principle of the invention is as follows:

the key shaft 19 of the key 18 is inserted into the lock core 5 along the circular groove of the key guiding column 9, and the key shaft 19 is positioned by the positioning hole 7, so that the key 18 can flexibly rotate. During the rotation of the key 18, the key teeth 21 contact the unlocking arc 16 and push the card 6 backward, so that all the cartridges 11 exit the grooves 4 of the housing 1 and the lock cylinder 5 and the lock shaft 2 rotate, the rotation of the lock shaft 2 controlling the opening of the lock and the door. When the key 18 is not in the lock core 5 for control, each catch plate 6 is under the action of the return spring 17, which is equivalent to that the return spring 17 pushes all the chucks 11 into the groove 4 of the housing 1, so that the housing 1 and the lock core 5 cannot rotate mutually, and the lock core is in a locked state.
