The sliding direction of the safety tongue assembly 30 is parallel to the sliding direction of the oblique tongue assembly 20, and the rotating shaft of the thumbwheel 31 is perpendicular to the sliding direction of the safety tongue assembly 30. The thumbwheel 31 is in transmission connection with the safety tongue assembly 30. When the thumbwheel 31 rotates, it drives the safety tongue assembly 30 to slide, thereby changing the locking state of the safety tongue module 3.

[0039] In some embodiments, the safety tongue assembly 30 includes a safety tongue 301 and a safety tongue movable plate 302. The safety tongue 301 is arranged on one end of the safety tongue movable plate 302, and a second tongue hole is arranged on the same side of the lock housing 1 as the first tongue hole; the safety tongue movable plate 302 is movably arranged in the lock housing 1, and the safety tongue 301 is telescopically arranged in the second tongue hole. A thumbwheel cantilever 311 is arranged on the thumbwheel 31, and a safety tongue slot is arranged on one end of the safety tongue assembly 30 facing the lock housing 1, and the thumbwheel cantilever 311 is arranged in the safety tongue slot. When the thumbwheel 31 drives the thumbwheel cantilever 311 to rotate toward the side close to the safety lock tongue 301, the thumbwheel cantilever 311 pushes the safety tongue movable plate 302 to slide outward, so that the safety lock tongue 301 extends out of the second lock tongue hole, and the safety lock tongue 301 enters a locked state; when the thumbwheel 31 drives the thumbwheel cantilever 311 to rotate toward the side away from the safety lock tongue 301, the thumbwheel cantilever 311 pushes the safety tongue movable plate 302 to slide inward, so that the safety lock tongue 301 is retracted into the second lock tongue hole, and the safety lock tongue 301 exits the locked state.

[0040] Furthermore, the safety tongue module 3 further includes a thumbwheel torsion spring. One end of the thumbwheel torsion spring is connected to the lock housing 1, and the other end is connected to the thumbwheel cantilever 311. The thumbwheel torsion spring is used to provide a pulling force to pull the thumbwheel cantilever 311 in a direction of extending out of the lock body or in a direction of retracting into the lock body, so that the safety tongue 301 can extend or retract into the second tongue hole more smoothly.

[0041] The linkage module 5 includes a linkage thumbwheel 50, a connecting rod 51, a linkage push rod 52 and a second reset assembly 53. The linkage thumbwheel 50 is rotatably arranged beside the thumbwheel 31, and a convex rib 501 is arranged on the linkage thumbwheel 50. One end of the connecting rod 51 is rotatably connected to the convex rib 501, and the other end is rotatably connected to the thumbwheel cantilever 311; the linkage thumbwheel 50 and the thumbwheel 31 are linked in rotation through the connecting rod 51.

[0042] Further, a second dial block 222 is provided on the side of the inclined tongue dial wheel 22 opposite to the first dial block 221 and away from the inclined locking tongue 201, and a third dial block 502 is provided on the side of the linkage dial wheel 50 opposite to the rib 501 and away from the safety locking tongue 301. The linkage push rod 52 is movably arranged in the lock housing 1. One end of the linkage push rod 52 abuts against the second dial block 222, and the other end faces the third dial block 502. In some embodiments, the sliding direction of the linkage push rod 52 is perpendicular to the sliding directions of the inclined tongue assembly 20 and the safety tongue assembly 30.

[0043] Please refer to Figures 5 to 6 , when the square steel rotating shaft 21 rotates to retract the inclined locking tongue 201, the inclined tongue dial wheel 22 rotates accordingly. The second dial block 222 pushes the linkage push rod 52 to move in a direction away from the inclined tongue dial wheel 22. At this time, if the safety locking tongue 301 is in the locked state, the linkage push rod 52 abuts against the third dial block 502. Subsequently, the linkage push rod 52 pushes the third dial block 502, causing the linkage dial wheel 50 to rotate. Then, through the connecting rod 51, the dial arm 311 is driven, causing the dial 31 to rotate, pushing the safety tongue movable plate 302 to slide inward, and causing the safety locking tongue 301 to retract into the second locking tongue hole, releasing the locked state of the safety locking tongue 301.

[0044] In some embodiments, the linkage dial wheel 50 includes two parallel dial rings that rotate coaxially and synchronously. The rib 501 and the third dial block 502 are respectively provided on the two dial rings.

[0045] Further, one end of the second reset assembly 53 is connected to the lock housing 1, and the other end is connected to the linkage push rod 52. The reset pulling force provided by the second reset assembly 53 pulls the linkage push rod 52 in a direction close to the inclined tongue dial wheel 22. When the inclined tongue dial wheel 22 is reset and no longer pushes the linkage push rod 52, the pulling force of the second reset assembly 53 resets the linkage push rod 52. Due to the reset of the linkage push rod 52, when the user rotates the dial 31 to lock the safety tongue module 3, the linkage push rod 52 will not hinder the locking of the safety tongue module 3.

[0046] In some embodiments, the inclined tongue dial wheel 22 is annular and sleeved on the square steel rotating shaft 21. An arc-shaped notch is provided at the lower end of the contact between the linkage push rod 52 and the second dial block 222, and the arc-shaped notch is matched with the outer peripheral shape of the inclined tongue dial wheel 22. When the linkage push rod 52 abuts against the second dial block 222, the inclined tongue dial wheel 22 abuts against the arc-shaped notch, improving the connection stability between the inclined tongue dial wheel 22 and the linkage push rod 52.

[0047] In some embodiments, the linkage push rod 52 includes one or more sections of movable rods; when there are multiple sections of movable rods, the sections of movable rods are staggered and arranged in parallel; the linkage push rod is provided with a movable assembly, and the lock housing 1 is provided with a movable matching piece that matches the movable assembly, and the linkage push rod moves relative to the lock body through the movable assembly. By staggering and arranging the sections of movable rods in parallel, the lateral distance between the top end (the end close to the second shift block 222) and the end (the end close to the third shift block 502) of the linkage push rod 52 can be changed, thereby matching the positions of the second shift block 222 and the third shift block 502, and reducing the volume of the linkage push rod 52, so that the movement of the linkage push rod 52 is smoother.

[0048] The main lock tongue module 4 includes a main lock tongue 401, a large square tongue assembly 402, a main lock tongue drive assembly 403 and a main lock tongue driven assembly 404. The main lock tongue 401 is connected to the large square tongue assembly 402, and the large square tongue assembly 402 is movably arranged in the lock housing 1; the lock housing 1 is provided with a third lock tongue hole, and the main lock tongue 401 is telescopically arranged in the third lock tongue hole. The main lock tongue drive assembly 403 rotates coaxially with the square steel shaft 21, and the main lock tongue driven assembly 404 is rotatably arranged beside the main lock tongue drive assembly 403, and is transmission-connected to the main lock tongue drive assembly 403, and the main lock tongue driven assembly 404 is transmission-connected to the large square tongue assembly 402.

[0049] When the square steel shaft 21 rotates to retract the oblique lock tongue 201 to release the locked state, if the main lock tongue 401 is in the locked state, the main lock tongue driving assembly 403 rotates with the square steel shaft 21, driving the main lock tongue driven assembly 404 to rotate; the main lock tongue driven assembly 404 drives the large square tongue assembly 402 to slide inward, causing the main lock tongue 401 to retract and release the locked state.

[0050] The safety tongue linkage quick-open lock of the utility model can release the locking state of the main lock tongue 401 and the safety tongue 301 by pressing the handle in the room. When the user releases the locking state of the inclined lock tongue 201, the locking state of the main lock tongue 401 and the safety tongue 301 are released at the same time. When the user presses the handle, the inclined tongue paddle wheel 22 pushes the linkage push rod 52, and the linkage push rod 52 pushes the linkage dial wheel 50 to retract the safety tongue 301; and after the user stops pressing the handle, the second reset component 53 pulls the linkage push rod 52 away from the linkage dial wheel 50, and the user can rotate the dial wheel 31 without resistance to lock the safety tongue 301.

[0051] Compared with the prior art, the safety tongue linkage quick-open lock of the utility model can realize the control of the safety tongue and the main lock tongue 401 by pressing the handle, which is convenient to operate and can be unlocked quickly from indoors. It also has a simple and reliable structure and low cost.

[0052] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and improvements.
