To facilitate further understanding, the unlocking and counter-locking of the lock is analyzed in more detail in the following combinations.

As shown in fig. 19, when the handles (the inner handle 1 and the outer handle 2) are horizontal, the handles are in the initial state (the unlocked state), and the functional pin 12 is positioned at the front end of the unlocking slot 1111. At the moment, the inner handle 1 and the outer handle 2 are pressed downwards to open the door; at this time, the inner handle 1 can be lifted and the outer handle 2 is driven to the blocking position to be locked (the reverse locking state), but the outer handle 2 is lifted to be fixed.

As shown in fig. 19 to 21, in the initial state, the process of lifting the inner handle 1 to the locking position (the locking state) can be referred to as follows, as shown in fig. 20, the inner handle 1 is lifted, when the driving wheel 7 rotates counterclockwise, F is divided into F normal + and F tangential, F normal + causes the function pin 12 to move outward, and the function pin 12 enters the locking groove 1112 from the front end of the unlocking groove 1111 through the outer locking limiting groove 1113. After entering the counter lock groove 1112, the function pin 12 can move to the end of the counter lock groove 1112 and be clamped into the outer unlocking limiting groove 1114, at this time, the inner handle 1 and the outer handle 2 both point to the upper side (vertical state), and at this time, the lock is in a counter lock state (locking state).

In the initial state, when the outer handle 2 is lifted up, as shown in fig. 21, when the driven wheel 8 tends to rotate counterclockwise, F is divided into F method and F tangential direction, and F method causes the functional pin 12 to move inwards to be in a locked state, that is, the functional pin 12 cannot enter the outer counter lock limiting groove 1113, that is, the outer handle 2 cannot actively perform counter lock.

As shown in fig. 23 to 23, when the function pin 12 enters the anti-lock groove 1112 and then moves to the end of the anti-lock groove 1112 and corresponds to the outer unlocking limiting groove 1114, as shown in fig. 24, that is, when the driving wheel 7 rotates counterclockwise to this position, F is divided into F normal + and F tangential, F normal + causes the function pin 12 to move outward and enter the outer unlocking limiting groove 1114, and the lock enters an anti-lock state (locking state), in which the inner handle 1 and the outer handle 2 both point upward and are in a vertical state.

As shown in fig. 25, after the lock enters the lock-backing state (lock state), if the outer handle 2 is rotated clockwise (pressed), the passive wheel 8 rotates clockwise F to be divided into F method + (forward direction in normal direction) and F tangential direction, and the F method + causes the functional pin 12 to have a tendency of moving outward and be clamped in the outer unlocking limit groove 1114, i.e. the outer handle 2 cannot actively unlock the lock.

As shown in fig. 26, when the lock enters the lock-backing state (lock state), if the inner handle 1 is rotated clockwise (pressed), the clockwise rotation F of the driver 7 is divided into F normal (reverse of normal direction) and F tangential, and F normal-causes the function pin 12 to move inward and enter the rear end of the lock-backing groove 1112, and continues to rotate clockwise (press) the inner handle 1, and the function pin 12 slides to the front end of the lock-backing groove 1112 to the front end of the lock-releasing groove 1111, so that the lock-backing state is released, and the lock is in the initial state.

According to the handle lockset provided by the embodiment of the invention, the inner handle 1 can reversely rotate at the initial position and drive the outer handle 2 to reversely rotate to the back locking position, and the outer handle 2 keeps the back locking position to prompt the lockset to be in the back locking state. The drive that handle 1 was carried backward including outer handle 2 also the antiport and keep the state after the antiport, outer handle 2 is behind the counter-lock promptly, can keep in the angle after the reversal, outer handle 2 is along with interior handle 1 reversal 90 degrees to ascending vertical state, the inside and outside user of door easily discerns the tool to lock and knows that someone in the door or the door has locked by the counter-lock to can not trade rotate outer handle 2 and try to unblank, avoided many awkwardness, user experience is good.

Example two:

fig. 29 shows that, unlike the track groove 111 in the first embodiment, in the present embodiment, the outer lock-back limiting groove is eliminated, and the lock-releasing groove 1111 and the lock-back groove 1112 are located in the same arc segment, that is, the lock-releasing groove 1111 and the lock-back groove 1112 have the same corresponding radius and are communicated with each other, and the inner handle 1 can be pressed down to unlock in the vertical state; because there is no back lock limiting groove, under the action of the driving wheel groove 71, the functional pin 12 can slide in the unlocking groove 1111 and the back lock groove 1112, the inner handle 1 can also be lifted to the vertical state for locking when in the horizontal state, and can also be pressed to unlock when in the horizontal state; the outer handle 2 cannot be pressed down to be unlocked in the vertical state; because there is no back lock limiting groove, the function pin 12 can slide in the unlocking groove 1111 and the back lock groove 1112 under the action of the driving wheel groove 71 and the driven wheel groove 81, and the outer handle 2 can be locked in a state of being lifted to the vertical state in a horizontal state and can also be pressed to be unlocked in the horizontal state. It is visible that interior handle 1 and outer handle 2 homoenergetic are carried to locking, but outer handle 2 can not push down the unblock. Different from the first embodiment, in the present embodiment, the outer handle 2 can also be lifted to lock, and is applicable to an application scenario that requires locking outside a door.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
