The guide member 210 is provided with a guide groove 211 with an opening facing downward or upward. The bottom of the guide groove 211 is provided with at least one inclined surface 212 facing the opening; the transmission rod 300 extends in the vertical direction. The transmission rod 300 can be movably connected to the rotating member 110 up and down. When the rotating member 110 rotates, it can drive the transmission rod 300 to rotate. The transmission rod 300 is provided with a second reset structure. The end of the transmission rod 300 is connected to the lock tongue assembly. The outer wall of the transmission rod 300 is provided with a radial protrusion 310. The protrusion 310 is inserted into the bottom of the guide groove 211.

[0036] Specifically, the heaven and earth door lock provided by the embodiment of the utility model triggers the unlocking device to drive the rotating member 110 to rotate, so that the rotating member 110 drives the transmission rod 300 to rotate, thereby driving the protrusion 310 to rotate to contact the inclined surface 212 of the guide groove 211. Since the position of the guide member 210 is fixed, as the protrusion 310 continues to rotate, the inclined surface 212 can force the protrusion 310 to rotate while moving along the inclined surface 212, thereby driving the transmission rod 300 to move vertically, and then driving the lock tongue assembly to retract. After the unlocking device stops being triggered, the rotating member 110 is reset through the first reset structure, and the transmission rod 300 is reset through the second reset structure.

[0039] Further, see Figure 4 According to some embodiments of the utility model, the raised portion 310 is cylindrical, which can make the movement of the raised portion 310 more stable and smooth. The bottom of the guide groove 211 is provided with an arc surface 213 corresponding to the shape of the raised portion 310.

[0040] Furthermore, in the embodiment of the utility model, the first reset structure can be reset by using elastic members such as tension springs or torsion springs, or by using other structures that can achieve the reset function. It can be determined according to actual needs and will not be elaborated here.

[0042] Furthermore, in the embodiment of the utility model, the second reset structure can be reset by using elastic members such as tension springs or torsion springs, or by using other structures that can achieve the reset function. It can be determined according to actual needs and will not be elaborated here.
[0043] Specifically, refer to Figure 2 According to some embodiments of the present invention, the lock tongue assembly includes an auxiliary lock tongue 220, a toggle member 230 and a third reset structure, the auxiliary lock tongue 220 is arranged on a side of the guide member 210 close to the opening, one end of the auxiliary lock tongue 220 is rotatably connected to the sky and earth lock 200, the other end of the auxiliary lock tongue 220 extends out of the sky and earth lock 200, the toggle member 230 is slidably connected to the sky and earth lock 200, the toggle member 230 is provided with a first connecting hole 231 extending in the up and down direction, the end of the transmission rod 300 is inserted into the first connecting hole 231, the toggle member 230 is provided with a first toggle part 232, the auxiliary lock tongue 220 is provided with a first driven part 221, the first toggle part 232 can push the first driven part 221 to retract the auxiliary lock tongue 220, and the third reset structure is used to reset the auxiliary lock tongue 220 and the toggle member 230.
[0044] It can be understood that by triggering the unlocking device to drive the rotating member 110 to rotate, the rotating member 110 drives the transmission rod 300 to rotate, thereby driving the protrusion 310 to rotate to contact the inclined surface 212 of the guide groove 211. Since the position of the guide member 210 is fixed, as the protrusion 310 continues to rotate, the inclined surface 212 can force the protrusion 310 to rotate while moving along the inclined surface 212, thereby driving the transmission rod 300 to move along the opening direction of the guide groove 211, and then pushing the toggle member 230 to move through the first connecting hole 231, thereby driving the first toggle part 232 to move to push the first driven part 221, thereby driving the lock tongue to rotate to retract, thereby realizing the unlocking of the sky and earth lock 200. When the unlocking device stops being triggered, the transmission rod 300 is reset through the second reset structure, and the auxiliary lock tongue 220 and the toggle member 230 are reset through the third reset structure.
[0045] Furthermore, in the embodiment of the utility model, the third reset structure can be reset by using elastic members such as tension springs or torsion springs, or by using other structures that can achieve the reset function. It can be determined according to actual needs and will not be elaborated here.
[0046] Further, see Figure 2 According to some embodiments of the utility model, two slide grooves 201 are symmetrically arranged on the inner walls on opposite sides of the sky and earth lock 200, and the two sides of the toggle member 230 are respectively slidably connected to the two slide grooves 201, and the slide grooves 201 can guide and limit the toggle member 230.
[0047] Specifically, refer to Figure 3 According to some embodiments of the utility model, the lock tongue assembly includes a latch 240 and a sliding seat 250. The latch 240 is arranged on the side of the guide member 210 away from the outlet. The latch 240 extends in the up and down direction. One end of the latch 240 extends out of the sky and earth lock 200, and the other end of the latch 240 is fixedly connected to the sliding seat 250. The sliding seat 250 is slidably connected in the sky and earth lock 200. A second connecting hole is provided on the side of the sliding seat 250 away from the latch 240. The end of the transmission rod 300 is inserted into the second connecting hole. The sliding seat 250 is provided with an elastic structure to force the sliding seat 250 to move toward the guide member 210.
[0048] It can be understood that by triggering the unlocking device to drive the rotating member 110 to rotate, the rotating member 110 drives the transmission rod 300 to rotate, thereby driving the protrusion 310 to rotate to contact the inclined surface 212 of the guide groove 211. Since the position of the guide member 210 is fixed, as the protrusion 310 continues to rotate, the inclined surface 212 can force the protrusion 310 to rotate while moving along the inclined surface 212, thereby driving the transmission rod 300 to move along the opening direction of the guide groove 211, so that the transmission rod 300 leaves the second connecting hole. At this time, the sliding seat 250 moves toward the guide member 210 under the elastic force of the elastic structure, thereby driving the pin 240 to retract. When the unlocking device stops being triggered, the transmission rod 300 is reset through the second reset structure, so that the transmission rod 300 can be inserted into the second connecting hole and push the sliding seat 250 to move in the direction away from the guide member 210, so that the sliding seat 250 overcomes the elastic force of the elastic structure so that the pin 240 can be reset.
[0049] Furthermore, in the embodiment of the utility model, the elastic structure can be achieved by using elastic parts such as tension springs or torsion springs, or by using other structures that can achieve the same function. It can be determined according to actual needs and will not be elaborated here.

[0051] It can be understood that, through the cooperation between the transmission rod 300 and the third connecting hole 111, better rotation transmission can be achieved, and when either side rotates, the other side can be driven to rotate synchronously.
[0052] Furthermore, in the embodiment of the present invention, the transmission rod 300 and the rotating member 110 may be connected in other structural ways as long as they can achieve the same function, which will not be described in detail here.
[0053] Further, see Figure 5 and Figure 6 According to some embodiments of the present invention, a plurality of transmission rods 300 are provided, and the plurality of transmission rods 300 are connected by a coupling 320, so that subsequent replacement and maintenance can be facilitated, and transmission rods 300 of different lengths can be replaced according to actual needs.

[0055] Furthermore, in the embodiment of the utility model, the fourth reset structure can be reset by using elastic members such as tension springs or torsion springs, or by using other structures that can achieve the reset function.
