[0031] Reference Figures 1 to 6 , a reverse lifting ecological door lock body, including a base body 10, a lock tongue 20, a drive frame 30, a drive seat 40, a drive member 50, a first toggle member 60 and a second toggle member 70;

[0032] The driving frame 30 is disposed in the seat body 10 and connected to the locking tongue 20;

[0033] The driving seat 40 is movably disposed in the seat body 10 and connected to the driving frame 30, and is used to drive the driving frame 30 to drive the locking tongue 20 to extend and retract;

[0034] The first toggle member 60 is disposed on one side of the driving member 50 and is linked to the inner handle, and the second toggle member 70 is disposed on the other side of the driving member 50 and is linked to the outer handle;

[0035] The driving member 50 is movably disposed on the driving seat 40 and has a first state, a second state and a third state. When the driving member 50 is in the second state, it is linked with the first toggle member 60 and the second toggle member 70 at the same time; when it is in the first state, it is linked with the first toggle member 60 and separated from the second toggle member 70; when it is in the third state, it is linked with the second toggle member 70 and separated from the first toggle member 60;

[0036] The first toggle member 60 or the second toggle member 70 can drive the driving member 50 in the second state to drive the driving seat 40 to rotate when rotating clockwise, or the first toggle member 60 can drive the driving member 50 to switch from the second state to the first state when rotating counterclockwise, or the second toggle member 70 can drive the driving member 50 to switch from the second state to the third state when rotating counterclockwise.

[0037] ① In this utility model, reference is made to Figure 1-3 6, the lock body is in a normal door locking state, at this time the driving member 50 is in the second state, that is, the positioning block extends into the second positioning groove 82, in this state, when the inner handle is rotated in the positive direction (clockwise), the first toggle member 60 will be driven to rotate clockwise, because the first toggle end 61 on the first toggle member 60 abuts against the driving member 50, thereby driving the driving member 50 and the driving seat 40 to rotate, and the driving end of the driving seat 40 pulls the driving frame 30 and the lock tongue 20 to retract inward, thereby realizing unlocking;

[0038] ②Reference Figure 3 and 4 , take indoor locking as an example to explain, specifically, Figure 3 The inner handle is rotated in the reverse direction (counterclockwise) in the state, which will drive the first toggle member 60 to rotate counterclockwise. Since the second toggle end 62 on the first toggle member 60 abuts against the driving member 50, the driving member 50 will be forced to switch from the second state to the first state, so that the driving member 50 is separated from the second toggle member 70 (in the case of no second toggle member 70, the driving member 50 is separated from the outer handle), that is, the driving member 50 releases the abutment with the third toggle end 71 on the second toggle member 70 and loses the linkage effect. At this time, no matter whether the outer handle is rotated clockwise or counterclockwise, it cannot drive the driving member 50 to rotate, and it is in an idling state, and the lock cannot be unlocked.

[0039] ③Reference Figure 3 and 5 , take outdoor anti-lock as an example (with a second toggle member 70) for explanation, specifically, Figure 3 The locking cam 72 is in the state of being unlocked, and the locking cam 72 is in the state of being unlocked, so that the second locking cam 72 is unlocked and the locking cam 72 is unlocked.

[0040] ④ Of course, the seat body 10 is provided with a first reset member 91 and a second reset member 92. The first toggle member 60 can drive the driving member 50 to switch from the first state to the second state through the first reset member 91 when rotating clockwise, and the second toggle member 70 can drive the driving member 50 to switch from the third state to the second state through the second reset member 92 when rotating clockwise, that is, return to the normal locked state;

[0041] ⑤ The advantage of the utility model is that: through the above structure, the outer handle can be idle when the inner handle rotates counterclockwise, and various components are integrated into the lock body, which reduces the requirements for the handle and is beneficial to the structural layout.

[0042] Preferably, the drive seat 40 is provided with a movable groove 41 running through both sides thereof, and the drive member 50 is arranged in the movable groove 41. The drive member 50 can extend to the outside of the two sides of the movable groove 41 when in the second state, so that the drive member 50 is simultaneously linked with the first toggle member 60 and the second toggle member 70, that is, at this time, unlocking can be achieved through the inner handle or the outer handle; or, when in the first state, one side extends to the outside of the movable groove 41 and the other side is completely accommodated in the movable groove 41, so that the drive member 50 is linked with the first toggle member 60 and separated from the second toggle member 70, that is, at this time, rotating the inner handle will cause the second toggle member 70 to rotate idly and cannot unlock; or, when in the third state, one side is completely accommodated in the movable groove 41 and the other side extends to the outside of the movable groove 41, so that the drive member 50 is linked with the second toggle member 70 and separated from the first toggle member 60, that is, at this time, rotating the outer handle will cause the first toggle member 60 to rotate idly and cannot unlock.

[0043] Preferably, the first toggle member 60 is provided with a first toggle end 61 and a second toggle end 62, and the second toggle member 70 is provided with a third toggle end 71 and a fourth toggle end 72.
