AI Technical Summary
The keys of the existing round cake lock are easy to copy, have low security, and lack password structure, resulting in reduced unlocking difficulty and security.
A high-strength high-key quantity round lock is designed, and a magnetic suction structure is used as a necessary condition for unlocking, which increases the key quantity. Only when the magnetic suction block is adjusted to the designated position of the high key can the lock core be driven to rotate, further increasing the amount of the key, thereby improving security.
By increasing the key quantity and magnetic suction structure, the security of the round lock is improved, so that even if you have the key, if you do not know how to move the magnetic suction block to the correct position, the unlocking operation cannot be performed.

DETAILED DESCRIPTION
[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] Example
[0018] like Figure 1-3As shown, the utility model proposes a high-strength and high-key round cake lock, including a round cake lock body 1 and a high-security key 3. A lock core 2 is rotatably connected in the round cake lock body 1, and a keyhole 21 for inserting the high-security key 3 is opened in the lock core 2. An installation groove 11 is opened at the upper end of the inner side wall of the round cake lock body 1, and a latch 12 is slidably connected in the installation groove 11. An ejection spring 13 is fixed between the upper end of the latch 12 and the side wall of the installation groove 11. A telescopic rod 22 is slidably connected to the upper end of the lock core 2 and aligned with the installation groove 11, and the bottom of the telescopic rod 22 extends into the keyhole 21, and the upper end of the telescopic rod 22 abuts against the bottom of the latch 12. A secret key slot 31 adapted to the telescopic rod 22 is provided at the upper end of the key 3, a slide slot 32 is provided at the bottom of the high-security key 3, a group of magnetic blocks 33 are slidably connected in the slide slot 32, a magnetic rod 23 is slidably connected to the bottom of the keyhole 21, a positioning slot 14 is provided at the bottom of the inner side wall of the round cake lock body 1, and the bottom of the magnetic rod 23 is inserted into the positioning slot 14, different bolts 12 and telescopic rods 22 have different lengths, the depth of the secret key slot 31 is adapted to the length of the bolt 12 and the telescopic rod 22, a limiting rod 5 is fixed at the bottom of the keyhole 21, and a limiting slot 51 adapted to the limiting rod 5 is provided at the front end of the high-security key 3 and the bottom of the magnetic block 33.
[0019] The number of magnetic blocks 33 is the same as the number of magnetic rods 23. Arc grooves 43 are provided on both sides of the magnetic blocks 33. Insert blocks 41 are equidistantly installed on the side walls of the slide groove 32. The ends of the insert blocks 41 are of arc structure and are inserted into the arc grooves 43. Telescopic grooves 4 are provided on the side walls of the slide groove 32 at positions corresponding to the insert blocks 41. A spring sheet 42 is fixed between the inner wall of the telescopic groove 4 and the insert blocks 41. A through hole 24 is provided at the bottom of the lock core 2 at a position corresponding to the magnetic rod 23. The upper end of the through hole 24 is of funnel-shaped structure and is aligned with the magnetic block 33.
[0020] In this embodiment, after the high-security key 3 is completely inserted into the keyhole 21, its secret key slot 31 and the telescopic rod 22 will be aligned one by one, so that the telescopic rod 22 can be lifted to a specified height, ensuring that the connection between the latch 12 and the upper end of the telescopic rod 22 is aligned with the connection between the lock cylinder 2 and the round cake lock body 1, and will not prevent the normal rotation of the lock cylinder 2. Secondly, the position of the magnetic block 33 will be aligned with the position of the perforation 24, and the magnetic rod 23 can be adsorbed to make it move upward, and the bottom of the magnetic rod 23 can be pulled out of the positioning slot 14 to avoid the magnetic rod 23 from preventing the lock cylinder 2 from rotating, and finally the purpose of unlocking is achieved, the secret key amount of the round cake lock is increased, and the purpose of improving security is achieved. Secondly, for the sliding of the magnetic block 33, after it slides to the specified position of the slide slot 32, the plug block 41 at this position can be used to insert into the arc slot 43 to maintain the position. Stable. Due to the arc structure at the end, it can be ensured that the position of the magnetic block 33 remains relatively stable without being subjected to external force. At the same time, the position of the magnetic block 33 can be adjusted by hand. Since there are multiple combinations of the positions of the magnetic block 33 in the slide groove 32, only when each position of the magnetic block 33 can correspond to the position of the magnetic rod 23 one by one, the magnetic energy can adsorb all the magnetic rods 23 to achieve the purpose of unlocking. Therefore, the distribution of the magnetic blocks 33 forms a structure similar to a password combination. After it is manually disrupted, if you do not know where to move the magnetic block 33 to correspond to the magnetic rod 23 one by one, even if you have the key, you cannot perform the unlocking operation, which further improves safety. When the key is inserted, due to the presence of the limit rod 5 in the keyhole 21, the magnetic block 33 with the limit slot 51 can only be inserted into the keyhole 21.
[0021] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
