[0035] Referring to Figure 2 and Figure 3 , the main lock tongue assembly 20 is movably arranged in the mounting shell 10 and selectively extends out of or retracts into the mounting shell 10. The main lock tongue assembly 20 includes a main lock tongue 22, a main lock tongue connecting plate 24, a first rotating piece 26, and a second rotating piece 28, wherein the main lock tongue connecting plate 24 is movably arranged in the bottom shell 11, the main lock tongue 22 is connected to one end of the main lock tongue connecting plate 24 and can extend out of or retract into the mounting shell 10, the first rotating piece 26 and the second rotating piece 28 are fixedly connected, the second rotating piece 28 is located between the first rotating piece 26 and the main lock tongue connecting plate 24 and is in transmission connection with the main lock tongue connecting plate 24. For example, the main lock tongue connecting plate 24 is provided with a guide inclined groove (not shown in the figure), the second rotating piece 28 is provided with a guide column (not shown in the figure), and the guide column can slide in the guide inclined groove, so that the rotation of the second rotating piece 28 can drive the main lock tongue connecting plate 24 to move, thereby driving the main lock tongue 22 to extend out of or retract into the mounting shell 10.

[0036] Referring to Figure 3 and Figure 4The lock core dial 30 is rotatably arranged in the mounting shell 10. The lock core dial 30 can be connected with a rotary knob indoors to realize stepless unlocking of the lock core double fast lock body 1 by rotating the rotary knob. The lock core dial 30 comprises a dial main body 32 and a dialing rod 34. The dial main body 32 is generally in a cylindrical structure and is rotatably arranged in the bottom shell 11. The dial main body 32 can be driven to rotate by a key, for example, the dial main body 32 can be provided with a key hole matched with the shape of the key. The dialing rod 34 protrudes from the dial main body 32 and is generally in a rectangular rod structure and can be used to dial an unlocking member. In the embodiment, the dialing rod 34 is integrally arranged with the dial main body 32. In other embodiments, the dialing rod 34 and the dial main body 32 can also be connected by welding, insertion, adhesion or other ways.

[0037] Please refer to Figure 4 and Figure 5 In the embodiment, the main lock tongue dialing member 40 is generally in an arc structure. The main lock tongue dialing member 40 is rotatably arranged in the mounting shell 10 and is in transmission connection with the main lock tongue assembly 20. The main lock tongue dialing member 40 can be in transmission connection with the second rotary piece 28, for example, the transmission mode between the main lock tongue dialing member 40 and the second rotary piece 28 can be gear meshing transmission, which can realize smooth transmission between the main lock tongue dialing member 40 and the second rotary piece 28. In other embodiments, the transmission mode between the main lock tongue dialing member 40 and the second rotary piece 28 can also be chain transmission, friction transmission or other transmission modes.

[0038] The main lock tongue dialing member 40 is arranged around part of the outer circumferential surface of the lock core dial 30 and has a gap between the main lock tongue dialing member 40 and the lock core dial 30, for example, the main lock tongue dialing member 40 is arranged around part of the outer circumferential surface of the dial main body 32, that is, the main lock tongue dialing member 40 is not arranged around the dial main body 32.

[0039] In an embodiment, the rotation axis of the main lock tongue dialing member 40 coincides with the rotation axis of the lock core dial 30, that is, the main lock tongue dialing member 40 is coaxially arranged with the lock core dial 30, so that the gap between the lock core dial 30 and the main lock tongue dialing member 40 is fixed during the rotation of the lock core dial 30 relative to the main lock tongue dialing member 40, thereby enabling the lock core dial 30 to smoothly drive the main lock tongue dialing member 40 to rotate, avoiding the situation that the rotation of the lock core dial 30 cannot drive the main lock tongue dialing member 40 to rotate due to the gap between the lock core dial 30 and the main lock tongue dialing member 40 being too large, and avoiding the situation that the lock core dial 30 interferes with the main lock tongue dialing member 40 due to the gap between the lock core dial 30 and the main lock tongue dialing member 40 being too small, thereby affecting the rotation of the lock core dial 30.

[0040] The main lock tongue pusher 40 is provided with spaced apart unlocking end 41 and locking end 43, specifically, the unlocking end 41 and the locking end 43 are oppositely arranged in the length direction of the main lock tongue pusher 40, that is, the unlocking end 41 and the locking end 43 are located at the opposite ends of the arc. The lock cylinder dial 30 can be abutted with the unlocking end 41, and the lock cylinder dial 30 can drive the main lock tongue assembly 20 to retract relative to the mounting shell 10 to achieve the unlocking of the stepless lock cylinder double fast lock body 1; the lock cylinder dial 30 can be abutted with the locking end 43, and the lock cylinder dial 30 can drive the main lock tongue assembly 20 to extend relative to the mounting shell 10 to achieve the locking of the stepless lock cylinder double fast lock body 1.

[0041] The unlocking end 41 and the locking end 43 are arranged on the rotation path of the lock cylinder dial 30, so that the rotation of the lock cylinder dial 30 is less than one revolution, and the unlocking end 41 can achieve the unlocking of the stepless lock cylinder double fast lock body 1, and the locking end 43 can achieve the locking of the stepless lock cylinder double fast lock body 1, and the unlocking or locking process has no gear and no pause, which realizes the stepless operation of the stepless lock cylinder double fast lock body 1, improves the user experience, and also realizes the lock cylinder double fast effect of the stepless lock cylinder double fast lock body 1, so that the stepless lock cylinder double fast lock body 1 can be quickly unlocked by rotating the lock cylinder dial 30 in an emergency, and the safety performance of the stepless lock cylinder double fast lock body 1 is improved. Compared with the lock body on the market, when the stepless lock cylinder double fast lock body 1 is an external reduction gearbox electric lock body, the use efficiency of the stepless lock cylinder double fast lock body 1 is greatly improved, and the power consumption is reduced by several times.

[0042] In the embodiment, on the basis that the radius of the arc of the main lock tongue pusher 40 is unchanged, the rotation angle of the lock cylinder dial 30 when the lock cylinder is unlocked or locked can be controlled by setting the distance between the unlocking end 41 and the locking end 43. The greater the distance between the unlocking end 41 and the locking end 43, the greater the rotation angle of the lock cylinder dial 30 when the lock cylinder is unlocked or locked, and vice versa.

[0043] In one embodiment, the main lock tongue pusher 40 has an unlocking position and a locking position, wherein the unlocking end 41 of the main lock tongue pusher 40 in the unlocking position is abutted with the lock cylinder dial 30, and when the main lock tongue pusher 40 is in the unlocking position, the main lock tongue assembly 20 is retracted to the maximum limit position; the locking end 43 of the main lock tongue pusher 40 in the locking position is abutted with the lock cylinder dial 30, and when the main lock tongue pusher 40 is in the locking position, the main lock tongue assembly 20 is extended to the maximum limit position. In addition, the main lock tongue pusher 40 also has an initial position, which is located between the unlocking position and the locking position, that is, the main lock tongue pusher 40 rotates from the unlocking position to the locking position through the initial position. In the embodiment, when the main lock tongue pusher 40 is in the initial position, the push rod 34 is rotated to the vertical direction, that is, the pusher extends in the vertical direction, wherein the vertical direction refers to the vertical direction of the stepless lock cylinder double fast lock body 1 in the use state.

[0044] In the embodiment, the rotation angle of the lock cylinder dial 30 is less than or equal to 110° from the unlocking position to the initial position, and from the initial position to the locking position, that is, the rotation angle of the lock cylinder dial 30 is less than 110° when the lock cylinder is unlocked or locked. When the rotation angle of the lock cylinder dial 30 exceeds 110°, the time for unlocking or locking is greatly increased, and when the stepless lock cylinder double fast lock body 1 is driven by a motor or a speed reducer, the power consumption required to drive the lock cylinder dial 30 to rotate to achieve unlocking or locking is greatly increased. When the rotation angle of the lock cylinder dial 30 is less than 110°, the manufacturing process requirements for the unlocking actuator are more stringent, which can greatly reduce the manufacturing yield of the unlocking actuator.

[0045] In the embodiment, the main lock tongue actuator 40 is provided with an arc-shaped slot 45 extending in the rotation direction of the main lock tongue actuator 40, and the main lock tongue actuator 40 can be installed in the bottom shell 11 through the arc-shaped slot 45. In one embodiment, the arc-shaped slot 45 includes first and second slots 451 and 453 spaced apart, both of which extend in the rotation direction of the main lock tongue actuator 40, that is, the first and second slots 451 and 453 are spaced apart in the length direction of the lock tongue actuator. The extension length of the first slot 451 is substantially equal to the extension length of the second slot 453. In another embodiment, the number of arc-shaped slots 45 can also be one, that is, the arc-shaped slot 45 only includes the first slot 451 or the second slot 453, which meets the purpose of the main lock tongue actuator 40 being able to be installed in the bottom shell 11.

[0046] Please refer to Figures 4 to 6 The stepless lock cylinder double fast lock body 1 further includes a latch assembly 50 movably arranged in the mounting shell 10 and selectively extended or retracted relative to the mounting shell 10. The latch assembly 50 includes a latch 51 and a latch connecting piece 53, the latch 51 is connected to the latch connecting piece 53 and can be extended out of the mounting shell 10 or retracted into the mounting shell 10, and the latch connecting piece 53 is movably arranged in the mounting shell 10. In addition, the latch assembly 50 further includes a latch spring 55, a first abutting piece 57 and a second abutting piece 59, the first abutting piece 57 is movably arranged in the mounting shell 10 along the moving direction of the latch assembly 50, the second abutting piece 59 is movably arranged in the bottom shell 11 and located at one end of the latch connecting piece 53 away from the latch 51, and the latch spring 55 is arranged around the latch connecting piece 53 and located between the latch 51 and the first abutting piece 57 to provide a force for the latch 51 to extend out of the mounting shell 10.

[0047] Please continue to refer to Figures 4 to 6The stepless lock cylinder double fast lock body 1 further comprises a latch bolt pushing member 60, which is rotatably arranged in the mounting housing 10 and is in transmission connection with the latch bolt assembly 50, so that rotation of the latch bolt pushing member 60 can drive the latch bolt assembly 50 to extend or retract relative to the mounting housing 10.

[0048] In the embodiment, the latch bolt pushing member 60 is arranged around part of the outer circumferential surface of the lock cylinder dial 30 and is arranged on the rotation path of the lock cylinder dial 30, for example, the latch bolt pushing member 60 is arranged on the rotation path of the pushing rod 34, so that rotation of the lock cylinder dial 30 can drive the latch bolt pushing member 60 to rotate, thereby driving the latch bolt assembly 50 to extend or retract relative to the mounting housing 10.

[0049] In the embodiment, the shape of the latch bolt pushing member 60 is substantially the same as that of the main bolt pushing member 40, that is, the latch bolt pushing member 60 is also substantially arc-shaped. In other embodiments, the latch bolt pushing member 60 can also have other shapes.

[0050] In one embodiment, the latch bolt pushing member 60 is stacked with the main bolt pushing member 40, for example, the latch bolt pushing member 60 is located between the bottom shell 11 and the main bolt pushing member 40. In other embodiments, the main bolt pushing member 40 can be located between the bottom shell 11 and the latch bolt pushing member 60.

[0051] The latch bolt pushing member 60 comprises a first end 61 and a second end 63 which are spaced apart, and both are arranged on the rotation path of the lock cylinder dial 30, wherein the first end 61 can be flush with the unlocking end 41, so that the lock cylinder dial 30 can abut against the first end 61 at the same time as abutting against the unlocking end 41. When the lock cylinder dial 30 abuts against the first end 61, continuing to rotate the lock cylinder dial 30 can drive the latch bolt assembly 50 to retract relative to the mounting housing 10, therefore, the first end 61 is arranged flush with the unlocking end 41, which can realize synchronous driving of the main bolt assembly 20 and the latch bolt assembly 50 to retract relative to the mounting housing 10 by rotation of the lock cylinder dial 30, thereby realizing unlocking of the stepless lock cylinder double fast lock body 1. In addition, the latch bolt pushing member 60 further comprises a transmission end 65 which is located between the first end 61 and the second end 63 and protrudes outward.

[0052] The latch bolt 60 is provided with a third slot 67 and a fourth slot 69, and the latch bolt 60 can be installed in the housing 11 through the third slot 67 and the fourth slot 69. The third slot 67 and the fourth slot 69 both extend along the rotation direction of the latch bolt 60, that is, the third slot 67 and the fourth slot 69 are spaced apart in the length direction of the latch bolt. The extension length of the third slot 67 is substantially equal to the extension length of the fourth slot 69, and is smaller than the extension length of the first slot 451 and the second slot 453. The third slot 67 is closer to the first end 61 than the fourth slot 69, and corresponds to the position of the first slot 451. The fourth slot 69 is closer to the second end 63 than the third slot 67, and corresponds to the position of the second slot 453.

[0053] In an embodiment, since the force for the latch bolt 51 to extend out of the housing 10 is provided by the latch bolt spring 55, the latch bolt 60 does not need to drive the latch bolt 51 to extend out of the housing 10 through the cylinder plug 30, and thus the arc length of the latch bolt 60 from the first end 61 to the second end 63 can be smaller than the arc length of the main latch bolt 40 from the unlocking end 41 to the locking end 43, which can save materials and reduce the weight of the stepless cylinder double fast lock body 1. In other embodiments, the arc length of the latch bolt 60 from the first end 61 to the second end 63 can also be equal to the arc length of the main latch bolt 40 from the unlocking end 41 to the locking end 43.

[0054] Please refer to Figures 5 to 7 In an embodiment, the stepless cylinder double fast lock body 1 further comprises a yoke assembly 70 and a latch transmission member 80.

[0055] The yoke assembly 70 comprises a yoke body 72, a first yoke plate 74 and a second yoke plate 76. The yoke body 72 is substantially in a columnar structure and can be used for inserting a handle square shaft, so that a user can rotate the yoke body 72 by rotating the handle. The first yoke plate 74 and the second yoke plate 76 are arranged at opposite ends of the yoke body 72. The first yoke plate 74 is in transmission connection with the first rotating plate 26, for example, the first yoke plate 74 and the first rotating plate 26 are in gear meshing transmission. The first yoke plate 74 is also located between the first abutting plate 57 and the second abutting plate 59, so that the rotation of the first yoke plate 74 can drive the latch assembly 50 to retract relative to the housing 10, thereby realizing the effect that the handle drives the latch assembly 50 to retract. One end of the second yoke plate 76 abuts against the latch transmission member 80, and the other end abuts against the first abutting plate 57, so as to drive the latch assembly 50 to extend or retract relative to the housing 10, thereby realizing the effect that the cylinder drives the latch assembly 50 to retract.

[0056] The shifter assembly 70 is in transmission connection with the main bolt assembly 20, for example, the shifter assembly 70 is in gear engagement with the first rotating piece 26 through the first shifter 74 to drive the second rotating piece 28 to rotate, thereby driving the main bolt connecting plate 24 to move, and further driving the main bolt 22 to extend out of the mounting shell 10 or to retract from the mounting shell 10, so as to realize the handle double-fast function of the stepless lock cylinder double-fast lock body 1, that is, the stepless lock cylinder double-fast lock body 1 provided by the present application simultaneously has the handle double-fast function and the lock cylinder double-fast function, so that the stepless lock cylinder double-fast lock body 1 can be quickly unlocked by rotating the lock cylinder dial 30 or the handle in an emergency, realizing the double protection of quick unlocking or locking, and improving the safety performance of the stepless lock cylinder double-fast lock body 1.
