[0029] Figure 4 A schematic structural diagram of a transmission lever 400 provided in one embodiment of the present application.

[0030] like Figure 4 As shown, in some embodiments, the first end 410 of the transmission lever is provided with a racetrack-shaped hole 440 extending along the vertical direction, and the shifting member 300 is provided with a connecting rod, which is inserted into the racetrack-shaped hole 440 .

[0031] The second end 420 of the transmission lever is a fan-shaped structure, and a gear portion 450 is provided at the edge of the fan-shaped structure. The transmission lever 400 is provided with a hinge portion 430 between the first end and the second end, and the hinge portion 430 is fixed to the first fixing hole 220 by a rotating shaft mechanism 800.

[0032] The pivot mechanism 800 includes a pivot base 810 and a fixing screw 820 . The pivot base 810 passes through the first fixing hole 220 . The transmission lever 400 can rotate around the pivot base 810 . The fixing screw 820 is fixedly connected to the pivot base 810 . Together, the two fix the transmission lever 400 on the mounting panel 200 .

[0033] When the shifting member 300 slides left and right in the slideway structure 210 , the connecting rod drives the first end 410 of the transmission shifting rod to swing around the hinge 430 through the runway hole 440 , and then drives the second end 420 of the transmission shifting rod to swing around the hinge 430 .

[0034] Figure 5 A schematic structural diagram of a safety gear 500 and a safety paddle 700 provided in an embodiment of the present application.

[0035] like Figure 5In some embodiments, the safety gear 500 includes a rotating shaft 510 and a gear 520 fixed to one end of the rotating shaft 510. Figure 1 and Figure 5 As shown, the rotating shaft 510 is installed in the second fixing hole 230 .

[0037] The lock body provided in the embodiment of the present application has the following working principle:

[0038] The control toggle member 300 slides left and right in the slide structure 210 of the mounting panel 200; the connecting rod of the toggle member 300 drives the first end 410 of the transmission lever to swing around the hinge part 430 as the center through the runway-shaped hole 440, and the gear part 450 of the second end 420 of the transmission lever makes a synchronous movement, that is, it swings around the hinge part 430 as the center; the gear part 450 drives the safety gear 500 to rotate around the axis of the second fixing hole 230; the safety gear 500 drives the safety paddle 700 inserted therein to move; the action of the safety paddle 700 eventually drives the safety tongue paddle (not shown) to move, thereby achieving the purpose of unlocking the safety lock tongue.

[0039] Compared with the traditional knob drive form, the lock body provided in the embodiment of the present application is composed of a transmission mechanism consisting of a toggle member 300, a transmission lever 400 and a safety gear 500 to complete the unlocking action of the safety lock tongue, which has the advantages of simple structure and easy operation; more importantly, it avoids the use of a knob structure, has little impact on the appearance of the lock, and allows for greater design space for the appearance of the lock.

[0040] It should be noted that the unlocking mechanism can be used as an independent module and adapted to different lock bodies. That is, the application scenario of the unlocking mechanism is not limited to the lock body shown in the figure, but can also be applied to other forms of lock bodies, as long as the main body 100 has a safety tongue puller (not shown) that can cooperate with the safety puller 700 of the unlocking mechanism.

[0041] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
