Description
Technical Field
[0001] The utility model belongs to the technical field of locks and relates to a lock core unlocking structure. Background Art
[0002] The lock body of a conventional lock is generally provided with a main lock tongue and an inclined tongue. When opening a door, the key is first inserted into the lock cylinder, and the lock cylinder is rotated to drive the main lock tongue and the inclined tongue to translate to unlock the door.
[0003] When unlocking, the lock core rotates and drives the main lock tongue to move horizontally. After the main lock tongue retreats into the lock body, it drives the oblique tongue to move horizontally back into the lock body. Therefore, when unlocking, it is necessary to turn the key continuously for multiple times to complete the unlocking. The main lock tongue and the oblique tongue cannot move synchronously, and the unlocking time is long. Summary of the invention
[0004] The utility model aims to solve the above problems existing in the existing locks and proposes an unlocking structure capable of realizing synchronous movement of a main locking tongue and an inclined tongue.

[0010] In the above-mentioned lock core unlocking structure, a baffle perpendicular to the lock core paddle is also fixed on the lock core paddle. The lock core rotates until it abuts against the baffle and pushes the baffle to rotate. One side of the transmission gear abuts against the baffle. When the lock core paddle rotates, the transmission gear is pushed to rotate synchronously through the baffle.
[0011] In the above-mentioned lock core unlocking structure, the push strip is longitudinally slidably arranged in the lock body, a plurality of guide grooves are opened on the push strip, a plurality of guide posts corresponding to the positions of the guide grooves are fixed in the lock body, and each guide post is inserted into the corresponding guide groove.

After unlocking, the main lock tongue is locked in the lock body to maintain the unlocking state. After the key is pulled out, the lock core paddle can rotate in the opposite direction through the guide limit structure, so that the inclined tongue can extend out of the lock body to avoid the inclined tongue being locked.

The inclined tongue paddle 13 is provided with a shift fork 1 9 and a shift fork 2 10, and the lock core paddle 12 is provided with a shift fork 3 11. The lock core paddle 12 rotates coaxially with the above-mentioned transmission gear 4. When the transmission gear 4 rotates, it drives the lock core paddle 12 to rotate synchronously, so that the shift fork 3 11 abuts against the push strip 8 and pushes the push strip 8 to translate forward, and the shift fork 2 10 abuts against the push strip 8, and the push strip 8 drives the shift fork 2 10 and the inclined tongue 3 fork to rotate, so that the shift fork 1 9 pushes the inclined tongue 3 to translate back into the lock body 1.
[0028] like Figure 7 As shown, a guide limiting structure is also provided between the transmission gear 4 and the lock core paddle 12, and the guide limiting structure includes a limiting piece 14 fixed in the lock body 1, two limiting columns 17 fixed on the transmission gear 4, a limiting arc groove 15 provided on the limiting piece 14, and a limiting arc groove 2 16 provided on the lock core paddle 12.

The limiting column 17 passes through the limiting arc groove 2 16 and the limiting arc groove 1 15 in sequence. When the key drives the lock core to rotate, the transmission gear 4 and the lock core paddle 12 rotate clockwise along the limiting arc groove 1 15 synchronously. After the key is pulled out, the lock core paddle 12 can rotate counterclockwise along the limiting arc groove 2 16 relative to the transmission gear 4 until the limiting arc groove 2 16 abuts against the limiting column 17. The lock core paddle 12 is also fixed with a baffle 21 which is perpendicular to the lock core paddle 12. The lock core rotates until it abuts against the baffle 21 and pushes the baffle 21 to rotate. One side of the transmission gear 4 abuts against the baffle 21. When the lock core paddle 12 rotates, the transmission gear 4 is pushed to rotate synchronously through the baffle 21.
[0029] The push bar 8 is longitudinally slidably arranged in the lock body 1, and a plurality of guide grooves 22 are provided on the push bar 8. A plurality of guide posts 23 corresponding to the positions of the guide grooves 22 are fixed in the lock body 1, and each guide post 23 is respectively inserted into the corresponding guide groove 22. The push bar 8 is fixed with a baffle plate 1 24 and a baffle plate 2 25 perpendicular to the push bar 8, and the baffle plate 1 24 and the baffle plate 2 25 are arranged in parallel and spaced in the longitudinal direction, the shift fork 3 abuts against the baffle plate 1 24, and the shift fork 2 10 abuts against the baffle plate 2 25. When the lock core paddle 12 rotates or the oblique tongue paddle 13 rotates, the push bar 8 can be pushed to translate through the baffle plate 1 24 or the baffle plate 2 25.
[0030] A guide seat 18 is fixedly provided in the lock body 1, and the oblique tongue 3 is slidably arranged on the guide seat 18 through a guide rod 19. A return spring 20 is sleeved on the guide rod 19 to push the oblique tongue 3 out of the lock body 1. A push piece 26 is fixedly provided on the guide rod 19, and the shift fork 19 abuts against the push piece. When the shift fork of the oblique tongue 3 rotates, the shift fork 19 pushes the push piece 26, the guide rod 19 and the oblique tongue 3 to translate.
[0031] The working principle of the utility model is as follows:
[0032] When unlocking, when the lock core is driven by the key to rotate clockwise, the lock core can drive the transmission gear 4 to rotate clockwise, and the transmission gear 4 drives the main gear 5 to rotate counterclockwise, and the main transmission shaft 6 pushes the main lock tongue 2 to translate back into the lock body 1 along the limit groove 7; the lock core paddle 12 rotates clockwise synchronously with the transmission gear 4 until the shift fork 3 11 abuts against the baffle 1 24 and pushes the push bar 8 to move downward, so that the baffle 2 25 pushes the shift fork 2 10 and the shift fork of the oblique tongue 3 to rotate clockwise, and the shift fork 1 9 pushes the push piece 26, the guide rod 19 and the oblique tongue 3 to translate back into the lock body 1;
[0033] After unlocking, the main lock tongue 2 is locked in the lock body 1 and remains in the unlocked state. After the key is pulled out, the position of the transmission gear 4 remains unchanged, the reset spring 20 pushes the inclined tongue 3 to extend out of the lock body 1, and the push piece 26 pushes the shift fork 1 9 and the inclined tongue paddle 13 to rotate counterclockwise. The shift fork 2 10 pushes the push bar 8 to move up, and drives the shift fork 3 11 and the lock core paddle 12 to rotate counterclockwise. The lock core paddle 12 rotates counterclockwise along the limit arc groove 2 16 relative to the transmission gear 4 until the inner wall of the limit arc groove 2 16 abuts against the limit column 17, and the lock core paddle 12 stops rotating. At this time, the outer circle of the inclined tongue 3 extends out of the lock body 1.
