[0002] The lock cylinder is the core part of a lock, and its structure determines the security and functionality of the lock. According to different shapes and structures, it can be divided into ball locks, rod-type lock cylinders, gear lock cylinders, etc. The above lock cylinder mechanisms can only allow the lock cylinder to rotate when the correct key is inserted, so as to achieve unlocking.

[0003] When the existing ball lock cylinder structure is in use, in order to achieve the purpose of unlocking, after inserting the key into the inside of the lock cylinder, the key still needs to be rotated to drive the lock cylinder to rotate, and then the lock can be opened. Since the lock cylinder needs to be rotated to unlock, it is not convenient for users to operate. At the same time, after long-term use, continuous friction occurs between the lock cylinder and the outer shell, which easily causes damage to the lock cylinder, thereby affecting the service life of the lock cylinder. Summary of the Invention

[0004] The purpose of the present invention is to provide an insert-and-open ball lock cylinder structure with two-sided locking points to solve the problems that the ball lock cylinder structure in the above background art is not convenient for users to operate and is prone to damage the lock cylinder.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An insert-and-open ball lock cylinder structure with two-sided locking points, including: an outer shell and a key body. A lock cylinder body is installed inside the outer shell. A key hole is opened at the top of the lock cylinder body, and the key body is inserted into the key hole.

[0006] A sawtooth rack is arranged on the surface of the key body. A through groove is opened in the middle of the lock cylinder body. An upper movable block and a lower movable block are arranged inside the through groove. A first fixed block is installed on the inner wall of the upper movable block. A second fixed block is installed on the inner side of the lower movable block. A first convex block and a second convex block are respectively installed on one side of the upper movable block and the lower movable block. A notch is opened on the inner side of the outer shell. An active spring is arranged between the first convex block and the second convex block.

[0007] Preferably, the notches are symmetrically opened on both sides of the outer shell, and the notches and the outer shell are of an integrally formed structure.

[0008] Preferably, the first convex block on the side of the upper movable block and the second convex block on the side of the lower movable block are symmetrically arranged.

[0009] Preferably, the upper movable block, the first fixed block and the first convex block are of an integrally formed structure.

[0010] Preferably, an integrated molding structure is formed among the lower movable block, the second fixed block and the second convex block.

[0011] Preferably, the first fixed block on the inner side of the upper movable block and the second fixed block on the inner side of the lower movable block are symmetrically arranged on the same side of the key body.

[0012] Preferably, a telescopic structure is formed among the upper movable block, the lower movable block and the through groove of the lock core body.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 3 , the present invention provides a technical solution: an insertable and openable ball lock core structure with two-sided lock points, including: an outer shell 1 and a key body 4. The lock core body 2 is installed inside the outer shell 1. A key hole 3 is opened at the top of the lock core body 2, and the key body 4 is inserted into the key hole 3;

[0026] A saw tooth strip 5 is arranged on the surface of the key body 4. A through groove 6 is opened in the middle of the lock core body 2. An upper movable block 7 and a lower movable block 8 are arranged inside the through groove 6. A first fixed block 9 is installed on the inner wall of the upper movable block 7, and a second fixed block 10 is installed inside the lower movable block 8. A first convex block 11 and a second convex block 12 are respectively installed on one side of the upper movable block 7 and the lower movable block 8. A notch 13 is opened on the inner side of the outer shell 1. An activity spring 14 is arranged between the first convex block 11 and the second convex block 12. The notches 13 are symmetrically opened on both sides of the outer shell 1. The notch 13 and the outer shell 1 are of an integrally formed structure. The first convex block 11 on the side of the upper movable block 7 and the second convex block 12 on the side of the lower movable block 8 are symmetrically arranged. The upper movable block 7, the first fixed block 9 and the first convex block 11 are of an integrally formed structure. The lower movable block 8, the second fixed block 10 and the second convex block 12 are of an integrally formed structure. The first fixed block 9 inside the upper movable block 7 and the second fixed block 10 inside the lower movable block 8 are symmetrically arranged on the same side of the key body 4. The upper movable block 7, the lower movable block 8 and the through groove 6 of the lock core body 2 form a telescopic structure. Multiple groups of through grooves 6 are evenly opened along the vertical direction of the lock core body 2. An upper movable block 7 and a lower movable block 8 are symmetrically installed inside each group of through grooves 6. The key body 4 passes through the hollow groove in the middle of the upper movable block 7 and the lower movable block 8. The upper movable block 7, the lower movable block 8 match the notch 13 on the inner wall of the outer shell 1.

[0027] During specific implementation, for the insertion-and-open ball lock cylinder structure with double-sided locking points, when unlocking, only need to insert the corresponding key body 4 into the keyhole 3, so that the sawtooth rack 5 on the side of the key body 4 is docked with the first fixing block 9 and the second fixing block 10 on the inner walls of the upper movable block 7 and the lower movable block 8. When inserting the key body 4, the protruding parts of the sawtooth rack 5 on the side of the key body 4 will respectively exert extrusion on the first fixing block 9 and the second fixing block 10, causing the first fixing block 9 and the second fixing block 10 to move closer to each other. Since the first fixing block 9 is installed inside the upper movable block 7 and the second fixing block 10 is installed inside the lower movable block 8, the mutual approach movement of the first fixing block 9 and the second fixing block 10 will cause the upper movable block 7 and the lower movable block 8 with a vertical offset design to move closer to each other and contract into the interior of the lock cylinder body 2 along the through groove 6 of the lock cylinder body 2. When the upper movable block 7 and the lower movable block 8 move closer to each other, they will synchronously drive the first convex block 11 on one side of the upper movable block 7 and the second convex block 12 on one side of the lower movable block 8 to move closer to each other, thereby exerting extrusion on the movable spring 14 between the first convex block 11 and the second convex block 12. Repeating the above steps will cause the upper movable blocks 7 and the lower movable blocks 8 in the other three lock cylinder bodies 2 to contract into the through grooves 6 of the three lock cylinder bodies 2. At this time, the upper movable block 7 and the lower movable block 8 are no longer docked with the notch 13 on the inner side of the outer shell 1, thus realizing the unlocking function.

[0028] When locking is required, only need to pull out the key body 4 from the keyhole 3 in the lock cylinder body 2. At this time, the first fixing block 9 and the second fixing block 10 on the inner walls of the upper movable block 7 and the lower movable block 8 are no longer subjected to the extrusion of the sawtooth rack 5 on the side of the key body 4. Then the movable spring 14 will reset and push the first convex block 11 and the second convex block 12 to move to both sides. When the first convex block 11 moves, it will drive the upper movable block 7 to move to one side, and the second convex block 12 will drive the lower movable block 8 to move to the other side, causing the upper movable block 7 and the lower movable block 8 to move out of the through groove 6 of the lock cylinder body 2 and be docked with the notch 13 on the inner side of the outer shell 1. At the same time, the upper movable blocks 7 and the lower movable blocks 8 in the other three lock cylinder bodies 2 will all move out of the through groove 6 of the lock cylinder body 2. Due to the limiting effect of the notch 13 on the inner side of the outer shell 1 on the upper movable block 7 and the lower movable block 8, the locking function can be realized. And because the upper movable block 7 and the lower movable block 8 move to both sides respectively, the lock cylinder body 2 has a double-sided locking point structure.

[0029] Refer to Figures 1 - 3It can be seen that during use, it is only necessary to insert the key body 4 into the lock core body 2, so that the saw tooth strip 5 on the side of the key body 4 presses against the first fixing block 9 and the second fixing block 10, and drives the upper movable block 7 and the lower movable block 8 to contract into the through groove 6 of the lock core body 2. At the same time, the movable spring 14 is pressed by the first convex block 11 and the second convex block 12, thereby realizing the unlocking function. Conversely, after the key body 4 is pulled out, under the action of the movable spring 14, the first convex block 11 and the second convex block 12, the upper movable block 7 and the lower movable block 8 will move out of the lock core body 2, thereby realizing the locking function, which is convenient for the user to operate. At the same time, since it is not necessary to rotate the entire lock core body 2, there is no friction between the lock core body 2 and the outer shell 1, thereby increasing the service life of the lock core body 2.

[0030] In summary, when the insert-type ball lock core structure with two-sided lock points is in use, it is only necessary to insert the corresponding key body 4 into the lock core body 2 through the key hole 3, and make the upper movable block 7 and the lower movable block 8 contract into the interior of the lock core body 2, thereby realizing the unlocking function. Conversely, after the key is pulled out, the movable spring 14 will push the upper movable block 7 and the lower movable block 8 to dock into the notch 13 of the outer shell 1, thereby realizing the locking function. This is the usage feature of the insert-type ball lock core structure with two-sided lock points. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
