[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, the utility model is a handle quick-opening electronic lock body for realizing separation of an inclined tongue and a square tongue, comprising a lock shell 1, an inclined tongue assembly 2, a square tongue 3, a first transmission bar 4, a second transmission bar 5, an inclined tongue paddle 6, a square tongue fork 7, and a handle dial head 8. The inclined tongue assembly 2 is installed in the lock shell 1, and a handle hole 11 for installing a handle is provided on the lock shell 1. The inclined tongue paddle 6 and the handle dial head 8 are movably connected at the handle hole 11 of the lock shell 1. The inclined tongue paddle 6 and the handle dial head 8 are butt-jointed. The square tongue fork 7 is movably connected to the lock shell 1 through a fixed shaft 71. The second transmission bar 5 is movably connected to the lock shell 1. The first transmission bar 4 is movably connected to the lock shell 1. On the second transmission bar 5, the first transmission bar 4 is provided with a first rivet column 42 and an S-shaped groove 41, the square tongue 3 is provided with a square tongue guide column 31, the square tongue guide column 31 is matched and connected with the S-shaped groove 41, the first rivet column 42 is located within the swing range of the square tongue fork 7, and the oblique tongue assembly 2 is located within the swing range of the oblique tongue paddle 6; when the handle is rotated to unlock, the oblique tongue paddle 6 and the handle head 8 rotate synchronously, the oblique tongue paddle 6 pushes the oblique tongue assembly 2 to retract, the handle head 8 moves the square tongue fork 7, and the square tongue fork 7 pushes the first rivet column 42 to drive the first transmission bar 4 to move, and the square tongue guide column 31 slides along the S-shaped groove 41 and drives the square tongue 3 to retract.

[0027] The handle drives the oblique bolt pick 6 through the handle hole 11, and the oblique bolt pick 6 rotates and contacts the oblique bolt assembly 2 to push the oblique bolt 21 back into the lock housing 1 from the extended state, thereby unlocking the oblique bolt 21; while the oblique bolt pick 6 rotates, the handle head 8 will also rotate synchronously in the same direction under the action of the handle, and the handle head 8 rotates to move the short arm 72 of the fork of the square bolt fork 7, thereby driving the long arm 73 of the fork at the other end to push the first rivet column 42, thereby driving the first transmission bar 4 to move upward, and at this time the square bolt guide column 31 will move along the S-shaped groove 41 on the first transmission bar 4, so that the square bolt 3 is pushed back into the lock housing 1 from the extended state, thereby unlocking the square bolt 3. That is, the synchronous quick opening and unlocking of the oblique bolt 21 and the square bolt 3 can be achieved by operating the handle indoors.

[0028] The first rivet column 42 may be covered with a first shaft sleeve 43 to protect the first rivet column 42 and to increase the friction between the square tongue fork 7 and the first shaft sleeve 43 so as to better transmit the force.

[0029] like Figure 3As shown in the figure, the S-shaped groove 41 includes a locking slot hole 411, an unlocking slot hole 412, and a transition inclined groove 413. The locking slot hole 411 is close to the side of the lock case 1, and the unlocking slot hole 412 is close to the inside of the lock case 1. The locking slot hole 411 and the unlocking slot hole 412 are connected by the transition inclined groove 413. When the square tongue guide post 31 is located in the locking slot hole 411, the square tongue 3 extends out of the side of the lock case 1. When the square tongue guide post 31 is located in the unlocking slot hole 412, the square tongue 3 retracts into the lock case 1. The matching positions of the locking slot hole 411, the unlocking slot hole 412 and the square tongue guide post 31 determine the extended or retracted state of the square tongue 3. The transition inclined groove 413, as the channel for the square tongue guide post 31 to switch between the locking slot hole 411 and the unlocking slot hole 412, will drive the square tongue 3 to gradually change from the extended state to the retracted state, or from the retracted state to the extended state. Through the trend of the S-shaped groove 41, the switching between the locked and unlocked states of the square tongue 3 is realized.

[0030] The handle quick-opening electronic lock body for realizing the separation of the diagonal tongue and the square tongue further includes a handle return torsion spring 81. The handle return torsion spring 81 is installed in the lock case 1. One end of the handle return torsion spring 81 abuts against the lock case 1, and the other end of the handle return torsion spring 81 abuts against the handle dial head 8. After unlocking with the handle, when the external force on the handle is removed, the handle return torsion spring 81 causes the handle dial head 8 to return under the action of the return elastic force. At the same time, the diagonal tongue dial 6 will also be linked with the handle dial head 8 to return synchronously. The diagonal tongue assembly 2 loses the acting force of the diagonal tongue dial 6, and the diagonal tongue 21 will extend out of the lock case 1 again.

[0031] The square tongue fork 7 is divided into a fork short arm 72 and a fork long arm 73. The fork short arm 72 and the fork long arm 73 use the fixed shaft 71 as the rotation lever center. When the handle dial head 8 rotates, it pushes the fork short arm 72, and the fork short arm 72 drives the fork long arm 73 to rotate to push the first rivet post 42. The fork short arm 72 and the fork long arm 73 form the two ends of the lever. The handle dial head 8 acts on the fork short arm 72 to drive the fork long arm 73 at the other end to rotate until the fork long arm 73 contacts the first rivet post 42 and pushes the first rivet post 42 to unlock the square tongue 3.

[0032] As Figure 2 and Figure 5 As shown in the figure, the handle quick-opening electronic lock body for realizing the separation of the diagonal tongue and the square tongue further includes a lock core mounting plate 12. The lock core mounting plate 12 is connected inside the lock case 1. The lock core mounting plate 12 is provided with a square tongue limit post 14. The square tongue 3 is provided with a square tongue limit straight groove 32. The length direction of the square tongue limit straight groove 32 is parallel to the movement direction of the square tongue 3. The square tongue limit straight groove 32 is movably connected to the square tongue limit post 14. The cooperation between the square tongue limit post 14 and the square tongue limit straight groove 32 restricts the movement direction of the square tongue 3 to linear movement left and right. Under the cooperation of the square tongue guide post 31 and the S-shaped groove 41, when locked, the square tongue 3 moves linearly to the left and extends out of the lock case 1. When unlocked, the square tongue 3 moves linearly to the right and retracts into the lock case 1.

[0033] The handle quick-opening electronic lock body for realizing the separation of the oblique tongue and the square tongue further includes a lock core drive gear 15 and a lock core driven gear set 9. A first tooth edge 44 is provided on the side of the first drive bar 4. The lock core drive gear 15 is connected to the lock core mounting plate 12, and the lock core driven gear set 9 is connected inside the lock housing 1. The lock core driven gear set 9 is respectively connected to the lock core drive gear 15 and the first tooth edge 44. When the lock core is unlocked, the lock core drives the first drive bar 4 through the lock core drive gear 15, the lock core driven gear set 9, and the first tooth edge 44.

[0034] A lock core hole 13 is provided in the middle of the lock core mounting plate 12. The lock core of the door lock can be assembled into the lock core hole 13 of the lock core mounting plate 12, and the lock core drive gear 15 surrounds the lock core hole 13. The lock core driven gear set 9 includes a first spur gear 91, a second double-layer gear 92, a third spur gear 93, and a fourth spur gear 94. The second double-layer gear 92 is connected to the square tongue limiting post 14. The third spur gear 93 and the fourth spur gear 94 are coaxially connected up and down and rotate synchronously. The first spur gear 91, the third spur gear 93, and the fourth spur gear 94 are assembled inside the lock housing 1. The first spur gear 91 meshes with the lock core drive gear 15 and the upper layer of the second double-layer gear 92 respectively. The lower layer of the second double-layer gear 92 meshes with the third spur gear 93, and the fourth spur gear 94 meshes with the first tooth edge 44. When unlocking the lock by turning the lock core with a key, the lock core drives the lock core drive gear 15 to rotate. The lock core drive gear 15 acts on the first tooth edge 44 through the transmission of the first spur gear 91, the second double-layer gear 92, the third spur gear 93, and the fourth spur gear 94 in sequence, so that the first drive bar 4 moves up and down to change the position between the S-shaped groove 41 and the square tongue guide post 31, realizing the process of unlocking or locking the square tongue 3 through the lock core.

[0035] The handle quick-opening electronic lock body for realizing the separation of the oblique tongue and the square tongue further includes a first drive bar guide post 45. The first drive bar 4 is provided with a first drive bar guide groove 46. The first drive bar guide post 45 is connected to the second drive bar 5, and the first drive bar guide groove 46 is movably connected to the first drive bar guide post 45. The cooperation of the first drive bar guide post 45 and the first drive bar guide groove 46 limits the maximum distance of the straight-line movement of the first drive bar 4 up and down. In cooperation with the use of the S-shaped groove 41, when the first drive bar guide post 45 matches the uppermost end of the first drive bar guide groove 46, the square tongue guide post 31 is located in the locking slot hole 411 and the square tongue 3 extends; when the first drive bar guide post 45 matches the lowermost end of the first drive bar guide groove 46, the square tongue guide post 31 is located in the unlocking slot hole 412 and the square tongue 3 retracts.

[0036] The handle quick-opening electronic lock body for realizing separation of the oblique tongue and the square tongue also includes a limit block 16 and a limit block spring 161. A limit convex edge 47 is provided on the side of the first transmission bar 4. The limit convex edge 47 divides the side of the first transmission bar 4 into a locking limit groove 48 and an unlocking limit groove 49. One end of the limit block spring 161 abuts against the lock housing 1, and the other end of the limit block spring 161 abuts against the limit block 16. When the square tongue 3 is extended or retracted, the limit block 16 is pressed against the locking limit groove 48 or the unlocking limit groove 49. The limiting convex edge 47 transitions to the side of the first transmission bar 4 through a beveled edge. The locking limiting groove 48 and the unlocking limiting groove 49 correspond to the state where the square tongue 3 is extended or retracted respectively. Under the action of the limiting block spring 161, the limiting block 16 always maintains an elastic force against the side of the first transmission bar 4. In the absence of external force, the limiting block 16 will be stuck in the locking limiting groove 48 and the unlocking limiting groove 49, limiting the position of the first transmission bar 4 and preventing it from moving. When the tongue 3 is converted from an extended state to a retracted state, the elastic force of the limit block spring 161 is overcome by the external force of the lock core unlocking or the tongue fork 7 pushing, and the limit block 16 slides from the locking limit groove 48 over the limit convex edge 47 into the unlocking limit groove 49; when the tongue 3 is converted from a retracted state to an extended state, the elastic force of the limit block spring 161 is overcome by the external force of the lock core locking, and the limit block 16 slides from the unlocking limit groove 49 over the limit convex edge 47 into the locking limit groove 48.

[0037] like Figure 1 , 2 As shown in , 4, the handle quick-open electronic lock body for realizing the separation of the oblique tongue and the square tongue also includes a motor 17, a motor gear 171, the second transmission bar 5 is provided with a second rivet column 52, a second tooth edge 51, the motor 17 is connected to and drives the motor gear 171, the motor gear 171 is meshed with the second tooth edge 51, the oblique tongue paddle 6 is provided with a first lever arm 61 and a second lever arm 62, the first lever arm 61 is connected to the oblique tongue assembly 2, the second lever arm 62 is connected to the second rivet column 52, and the second rivet column 52 is located on the moving track when the first transmission bar 4 is unlocked. When the motor 17 unlocks the oblique tongue 21, the motor 17 drives the second transmission bar 5 through the motor gear 171 and the second tooth edge 51, and the second rivet column 52 moves with the second transmission bar 5 and pushes the second lever arm 62, so that the first lever arm 61 pushes the oblique tongue assembly 2 to retract.

[0038] A main board 18 is also installed in the lock housing 1 to control the rotation of the motor 17. The motor 17 drives the second transmission bar 5 to move up and down linearly through the motor gear 171 and the second tooth edge 51. When the second transmission bar 5 moves upward, it will drive the second rivet column 52 to move upward together. At this time, the second rivet column 52 will move the second lever arm 62 of the latch bolt paddle 6, thereby synchronously driving the first lever arm 61 of the latch bolt paddle 6 to rotate, so as to push the latch bolt assembly 2 and push the latch bolt 21 from the extended state to the retracted state. The movement process of the motor 17 is that after the latch bolt 21 is unlocked, the power will be turned off to release the push on the latch bolt assembly 2, and the latch bolt 21 will be released so that the latch bolt 21 will extend out of the lock housing 1 again, which is convenient for the next door locking operation. The second rivet column 52 can be covered with a second shaft sleeve 53 on the outside, which plays a role in protecting the second rivet column 52, and can also increase the friction between the second lever arm 62 and the second shaft sleeve 53 and the top of the first transmission bar 4, so that the force is better transmitted.

[0039] When the first transmission bar 4 unlocks the square tongue 3 upward, the top end of the first transmission bar 4 will hit the second rivet column 52 and simultaneously drive the second rivet column 52 to move upward, thereby pushing the oblique tongue paddle 6 to unlock the oblique tongue 21 .

[0040] The handle quick-open electronic lock body for realizing the separation of the oblique tongue and the square tongue further comprises a second transmission bar guide column 54, the second transmission bar 5 is provided with a second transmission bar guide groove 55, the second transmission bar guide column 54 is connected to the lock housing 1, and the second transmission bar guide groove 55 is movably connected to the second transmission bar guide column 54. The cooperation between the second transmission bar guide column 54 and the second transmission bar guide groove 55 limits the maximum distance of the second transmission bar 5 to move up and down in a straight line, so that the second transmission bar 5 can just keep the oblique tongue 21 in an extended or retracted state when it moves to the two maximum distances up and down.

[0041] The oblique tongue assembly 2 includes an oblique tongue 21, an oblique tongue guide block 22, and an oblique tongue return spring 23. An oblique tongue guide groove 24 is provided on the lock housing 1. The oblique tongue guide block 22 is slidably connected to the oblique tongue guide groove 24. One end of the oblique tongue return spring 23 abuts against the lock housing 1, and the other end of the oblique tongue return spring 23 abuts against the oblique tongue guide block 22. The oblique tongue 21 is connected to the oblique tongue guide block 22, and the oblique tongue paddle 6 is docked with the oblique tongue guide block 22. Without the action of external force, the elastic force of the oblique tongue return spring 23 acts on the oblique tongue guide block 22, so that the oblique tongue 21 remains in a state of protruding from the lock housing 1, and the matching structure of the oblique tongue guide block 22 and the oblique tongue guide groove 24 limits the moving direction of the oblique tongue 21. The position where the first paddle arm 61 of the oblique tongue paddle 6 acts on the oblique tongue guide block 22 is opposite to the position of the oblique tongue return spring 23. When the first paddle arm 61 of the oblique tongue paddle 6 pushes the oblique tongue guide block 22, it will overcome the elastic force of the oblique tongue return spring 23 to make the oblique tongue guide block 22 move along the oblique tongue guide groove 24, thereby compressing the oblique tongue return spring 23 to retract the oblique tongue 21 into the lock housing 1. When the external force of the oblique tongue paddle 6 is removed, the oblique tongue 21 will protrude from the lock housing 1 again under the action of the oblique tongue return spring 23.

[0042] The handle quick-opening electronic lock body of the present utility model that realizes the separation of the oblique tongue and the square tongue has the following several operating states:

[0043] Such as Figure 6 shown, the process of electrically opening the oblique tongue 21: The main board 18 assembly is powered and sends a signal to the motor 17. The motor 17 drives the motor gear 171 to rotate clockwise, and drives the second transmission bar 5 to move upward along the second transmission bar guide post 54 and the second transmission bar guide groove 55 through the second tooth edge 51. At this time, the second rivet post 52 and the second bushing 53 riveted on the second transmission bar 5 will force the oblique tongue paddle 6 to rotate around the handle paddle head 8, and at the same time force the oblique tongue guide block 22 to move backward along the oblique tongue guide groove 24 and make the oblique tongue 21 overcome the elastic force of the oblique tongue return spring 23 to retract to complete unlocking; after the motor 17 is powered off and there is no force, the oblique tongue 21 returns to the protruding state under the elastic force of the oblique tongue 21 return compression spring.

[0044] Such as Figure 7 shown, the process of locking the lock core: The lock core paddle head rotates clockwise through the lock core hole 13 to drive the lock core transmission gear 15, the first straight gear 91, the second double-layer gear 92, the third straight gear 93, and the fourth straight gear 94 to rotate synchronously, and at the same time drives the first transmission bar 4 to move downward against the elastic force of the limit block spring 161. At the same time, the square tongue guide post 31 riveted on the square tongue 3 moves along the S-shaped groove 41 on the first transmission bar 4 to realize the protrusion of the square tongue 3 to achieve the locking function.

[0045] Such as Figure 8As shown in the figure, the process of unlocking the lock core: The lock core pick rotates counterclockwise through the lock core hole 13 and drives the lock core transmission gear 15, the first spur gear 91, the second double-layer gear 92, the third spur gear 93, and the fourth spur gear 94 to rotate synchronously. At the same time, it drives the first transmission bar 4 to move upward against the elastic force of the limit block spring 161. At the same time, the square tongue guide post 31 riveted on the square tongue 3 moves along the S groove on the first transmission bar 4 to realize the retraction of the square tongue 3; while the first transmission bar 4 continues to move upward, it pushes the second rivet post 52 and the second bushing 53 riveted on the second transmission bar 5, and at the same time forces the inclined tongue dial 6 to rotate around the handle pick 8, and at the same time forces the inclined tongue guide block 22 to move backward along the inclined tongue guide groove 24 and makes the inclined tongue 21 retract against the elastic force of the inclined tongue 21 return compression spring to complete the unlocking.

[0046] As Figure 9 As shown in the figure, the process of quickly unlocking the handle: The handle drives the handle pick 8 to rotate clockwise through the square bar to drive the handle dial, and at the same time forces the inclined tongue guide block 22 to move backward along the inclined tongue guide groove 24 and makes the inclined tongue 21 retract against the elastic force of the inclined tongue return spring 23. When the handle pick 8 rotates, it synchronously forces the square tongue fork 7 to rotate around the fixed shaft 71, and at the same time drives the first rivet post 42, the first bushing 43, and the first transmission bar 4 to move upward and drives the square tongue guide post 31 riveted on the square tongue 3 to move along the S-shaped groove 41 on the first transmission bar 4 to realize the retraction of the square tongue 3. Thus, the simultaneous retraction action of the inclined tongue 21 and the square tongue 3 is completed.

[0047] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present invention.
