DETAILED DESCRIPTION

[0017] 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.

[0018] like Figure 1 and Figure 2As shown, a handle quick-opening electronic lock body for realizing separation of an inclined tongue and a square tongue of the present invention comprises a lock housing 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 housing 1, and a handle hole 11 for installing a handle is provided on the lock housing 1. The inclined tongue paddle 6 and the handle dial head 8 are movably connected at the handle hole 11 of the lock housing 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 housing 1 through a fixed shaft 71. The second transmission bar 5 is movably connected to the lock housing 1. The first transmission bar 4 is movably connected to the first transmission bar 4. 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.

[0019] 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.

[0020] 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.

[0021] like Figure 3As shown, the S-shaped groove 41 includes a locking slot 411, an unlocking slot 412, and a transition bevel 413. The locking slot 411 is close to the side of the lock housing 1, and the unlocking slot 412 is close to the inside of the lock housing 1. The locking slot 411 and the unlocking slot 412 are connected through the transition bevel 413. When the square tongue guide column 31 is located in the locking slot 411, the square tongue 3 extends out of the side of the lock housing 1. When the square tongue guide column 31 is located in the unlocking slot 412, the square tongue 3 retracts into the inside of the lock housing 1. The matching positions of the locking slot 411, the unlocking slot 412 and the square tongue guide column 31 determine whether the square tongue 3 is in an extended or retracted state. The transition bevel 413, as a channel for the square tongue guide column 31 to switch between the locking slot 411 and the unlocking slot 412, will drive the square tongue 3 to gradually change from an extended state to a retracted state, or from a retracted state to an extended state. The direction of the S-shaped groove 41 realizes the switching of the locking and unlocking states of the square tongue 3.

[0022] The handle quick-open electronic lock body that realizes the separation of the oblique bolt and the square bolt also includes a handle reset torsion spring 81, which is installed in the lock housing 1, one end of the handle reset torsion spring 81 abuts against the lock housing 1, and the other end of the handle reset torsion spring 81 abuts against the handle dial head 8. After the lock is unlocked by the handle, when the external force of the handle is withdrawn, the handle reset torsion spring 81 returns the handle dial head 8 under the action of the reset elastic force, and the oblique bolt pick 6 will also return synchronously with the handle dial head 8, the oblique bolt assembly 2 loses the force of the oblique bolt pick 6, and the oblique bolt 21 will extend out of the lock housing 1 again.

[0023] The square tongue fork 7 is divided into a short fork arm 72 and a long fork arm 73. The short fork arm 72 and the long fork arm 73 use the fixed shaft 71 as the rotation lever center. When the handle head 8 rotates, the short fork arm 72 is pushed, and the short fork arm 72 drives the long fork arm 73 to rotate to push the first rivet column 42. The short fork arm 72 and the long fork arm 73 form the two ends of the lever. The handle head 8 acts on the short fork arm 72 to drive the long fork arm 73 at the other end to rotate until the long fork arm 73 contacts the first rivet column 42 and pushes the first rivet column 42 to unlock the square tongue 3.

[0024] like Figure 2 and Figure 5 As shown, the handle quick-open electronic lock body for realizing the separation of the oblique tongue and the square tongue also includes a lock core mounting plate 12, the lock core mounting plate 12 is connected in the lock housing 1, a square tongue limiting column 14 is provided on the lock core mounting plate 12, and the square tongue 3 is provided with a square tongue limiting straight groove 32, the length direction of the square tongue limiting straight groove 32 is parallel to the movement direction of the square tongue 3, and the square tongue limiting straight groove 32 is movably connected to the square tongue limiting column 14. The cooperation of the square tongue limiting column 14 and the square tongue limiting straight groove 32 limits the movement direction of the square tongue 3 to linear movement to the left and right. Under the cooperation of the square tongue guide column 31 and the S-shaped groove 41, the square tongue 3 moves linearly to the left to extend out of the lock housing 1 when locked, and moves linearly to the right to retract into the lock housing 1 when unlocked.

[0025] The handle quick-opening electronic lock body that realizes the separation of the oblique tongue and the square tongue also includes a lock core transmission gear 15 and a lock core driven gear set 9. The side of the first transmission bar 4 is provided with a first tooth edge 44. The lock core transmission gear 15 is connected to the lock core mounting plate 12. The lock core driven gear set 9 is connected in the lock housing 1. The lock core driven gear set 9 is respectively connected to the lock core transmission gear 15 and the first tooth edge 44. When the lock core is unlocked, the lock core drives the first transmission bar 4 through the lock core transmission gear 15, the lock core driven gear set 9 and the first tooth edge 44.

[0026] A lock core hole 13 is provided in the middle of the lock core mounting plate 12, and 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 transmission 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 limit column 14, and 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 in the lock housing 1, and the first spur gear 91 is respectively meshed with the lock core transmission gear 15 and the upper layer of the second double-layer gear 92, the lower layer of the second double-layer gear 92 is meshed with the third spur gear 93, and the fourth spur gear 94 is meshed with the first tooth edge 44. When the lock cylinder is unlocked by turning the key, the lock cylinder drives the lock cylinder transmission gear 15 to rotate. The lock cylinder transmission 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 transmission bar 4 moves up and down to change the position between the S-shaped groove 41 and the square tongue guide column 31, thereby realizing the process of unlocking or locking the square tongue 3 by the lock cylinder.

[0027] The handle quick-open electronic lock body for realizing the separation of the oblique tongue and the square tongue also includes a first transmission bar guide column 45, the first transmission bar 4 is provided with a first transmission bar guide groove 46, the first transmission bar guide column 45 is connected to the second transmission bar 5, and the first transmission bar guide groove 46 is movably connected to the first transmission bar guide column 45. The cooperation of the first transmission bar guide column 45 and the first transmission bar guide groove 46 limits the maximum distance of the first transmission bar 4 to move up and down in a straight line, and with the use of the S-shaped groove 41, when the first transmission bar guide column 45 matches the first transmission bar guide groove 46 at the uppermost end, the square tongue guide column 31 is located in the locking slot 411, and the square tongue 3 extends; when the first transmission bar guide column 45 matches the first transmission bar guide groove 46 at the lowermost end, the square tongue guide column 31 is located in the unlocking slot 412, and the square tongue 3 retracts.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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 .

[0032] 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.

[0033] The inclined bolt assembly 2 includes an inclined bolt 21, an inclined bolt guide block 22, and an inclined bolt return spring 23. The lock housing 1 is provided with an inclined bolt guide groove 24. The inclined bolt guide block 22 is slidably connected to the inclined bolt guide groove 24. One end of the inclined bolt return spring 23 abuts against the lock housing 1, and the other end of the inclined bolt return spring 23 abuts against the inclined bolt guide block 22. The inclined bolt 21 is connected to the inclined bolt 21 guide block, and the inclined bolt paddle 6 is connected to the inclined bolt guide block 22. In the absence of external force, the elastic force of the inclined bolt return spring 23 will act on the inclined bolt guide block 22, so that the inclined bolt 21 remains in a state of extending out of the lock housing 1, and the matching structure of the inclined bolt guide block 22 and the inclined bolt guide groove 24 defines the moving direction of the inclined bolt 21. The position where the first lever arm 61 of the inclined bolt paddle 6 acts on the inclined bolt guide block 22 is opposite to the position of the inclined bolt return spring 23. When the first lever arm 61 of the inclined bolt paddle 6 pushes the inclined bolt guide block 22, it will overcome the elastic force of the inclined bolt return spring 23 to move the inclined bolt guide block 22 along the inclined bolt guide groove 24, thereby compressing the inclined bolt return spring 23 to retract the inclined bolt 21 into the lock housing 1. When the external force of the inclined bolt paddle 6 is withdrawn, the inclined bolt 21 will re-extend from the lock housing 1 under the action of the inclined bolt return spring 23.

[0034] The handle quick-open electronic lock body for realizing the separation of the oblique tongue and the square tongue of the present invention has the following operating states: like Figure 6 As shown, the process of electrically opening the latch bolt 21: the main board 18 component supplies power 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 column 54 and the second transmission bar guide groove 55 through the second tooth edge 51. At this time, the second rivet column 52 and the second shaft sleeve 53 riveted on the second transmission bar 5 will force the latch bolt pick 6 to rotate around the handle head 8, and at the same time force the latch bolt guide block 22 to move backward along the latch bolt guide groove 24 and make the latch bolt 21 overcome the elastic force of the latch bolt reset spring 23 to retract and complete the unlocking; after the motor 17 is powered off, the latch bolt 21 returns to the extended state under the elastic force of the latch bolt 21 reset compression spring under the powerless action.

[0035] like Figure 7 As shown, the locking process of the lock core: the lock core dial head rotates clockwise through the lock core hole 13 to drive 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, and at the same time drives the first transmission bar 4 to overcome the elastic force of the limit block spring 161 and move downward. At the same time, the square tongue guide column 31 riveted on the square tongue 3 moves along the S-shaped groove 41 on the first transmission bar 4 to realize the extension of the square tongue 3 to achieve the locking function.

[0036] like Figure 8As shown, the lock core unlocking process: the lock core dial head 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, and at the same time drives the first transmission bar 4 to overcome the elastic force of the limit block spring 161 and move upward, and at the same time the square tongue guide column 31 riveted on the square tongue 3 moves along the S groove on the first transmission bar 4 to retract the square tongue 3; the first transmission bar 4 continues to move upward while pushing the second rivet column 52 and the second shaft sleeve 53 riveted on the second transmission bar 5, and at the same time forces the oblique tongue pick 6 to rotate around the handle dial head 8, and at the same time forces the oblique tongue guide block 22 to move backward along the oblique tongue guide groove 24 and causes the oblique tongue 21 to overcome the elastic force of the oblique tongue 21 reset compression spring and retract to complete the unlocking.

[0037] like Fig. 9 As shown, the handle quick-open unlocking process: the handle drives the handle dial head 8 to rotate clockwise through the square steel to drive the handle dial piece, 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 reset spring 23; when the handle dial head 8 rotates, the square tongue fork 7 is simultaneously forced to rotate around the fixed shaft 71, and at the same time drives the first rivet column 42, the first shaft sleeve 43, and the first transmission bar 4 to move upward and drives the square tongue guide column 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, thereby completing the simultaneous retraction of the inclined tongue 21 and the square tongue 3.

[0038] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
