The outer handle 2 is fixedly connected with the end cover 3.
The inner handle 12 is arranged on one end face of the inner panel 11; the other end face of the inner panel 11 is provided with a lock body 4, and the lock body 4 is provided with a square core 19.
The inner panel 11 and the outer panel 1 are in butt joint connection, and the square core 19 is inserted into a square core hole on the end cover 3; the inner handle 12 is fixedly connected with one end of the square core 19.
The lock body 4 comprises a lock tongue 13, a positioning plate 14, a linkage plate 15, a stop plate 16, a second spring 17, a third spring 18, a square core 19, a transmission piece 20 and a lock shell 21, wherein a mounting hole is formed in a panel of the lock shell 21, and the square core 19 is assembled in the mounting hole. One end of the square core 19, which is arranged in the inner cavity of the lock shell 21, is sleeved with a transmission piece 20, one end of the transmission piece 20 is connected with a linkage plate 15, the other end of the linkage plate 15 is sleeved on a first connecting piece, and the first connecting piece is arranged in the inner cavity of the lock shell 21.
The two ends of the first connecting piece are respectively connected with the side wall of the transmission piece 20 and the side wall of the lock shell 21.
The first connecting piece is sleeved with a second spring 17, and the second spring 17 is arranged between the lock shell 21 and the linkage plate 15.
The locating plate 14 is inserted into the inner cavity of the lock housing 21.
The lock tongue 13 is arranged on the outer side of the lock shell 21; the lock tongue 13 is fixed with a second connecting piece, and the free end of the second connecting piece sequentially passes through the side wall of the lock shell 21, the positioning plate 14 and the linkage plate 15 to be fixedly connected.
The side wall of the square core 19 is slidably connected with a stop plate 16, and the other end of the stop plate 16 is mounted on the side wall of the lock shell 21.
The other end of the stop plate 16 is sleeved with a third spring 18.
The axes of the second spring 17 and the third spring 18 are parallel to each other.
As shown in fig. 4, the square core 19 has a four-step shaft structure, which is a first step shaft 1901, a second step shaft 1902, a third step shaft 1903 and a fourth step shaft 1904 in sequence, wherein the first step shaft, the third step shaft and the fourth step shaft are all square structures, and the second step shaft has a cylindrical structure and is a transition section between the first step shaft and the third step shaft; a mounting groove 1905 is provided between the third step shaft and the fourth step shaft.
One end of the stopper plate 16 slides back and forth along the side wall of the fourth stepped shaft 1904.
One end of the square core 19, which is arranged at the outer side of the lock shell 21, is sleeved with a spring baffle 6 and a first spring 5, wherein,
in general, the user can rotate the outer handle 2 to drive the transmission member 20 to rotate, and the transmission member 20 drives the linkage plate 15 to linearly move to drive the lock tongue 13 to move back and forth; and the lock tongue 13 is separated from the locker 9 and the latch plate 10 mounted on the door frame, thereby opening the door.
When a user enters the house, the square core 19 can be separated from the square core hole of the outer handle 2 by pulling the inner handle 12 inwards, the handle lock enters an abnormal working state, and when another person rotates the outer handle from the outside, the force cannot be transmitted to the square core 19, so that the door cannot be opened from the outside at this time.
When the user opens the door from the inside, and the door is closed again, the handle lock resumes the normal condition, i.e. the user can open the door by rotating the inner and outer handles.
Principle of locking: when the user pulls the inner handle 12 inward to a certain distance, the stopper plate 16 is inserted into the installation groove 1905 of the square core 19 by the pushing force of the third spring 18, as shown in fig. 3, so that when the user releases his or her hand, the square core 19 still leaves the square core hole of the outer handle 2, and thus the door cannot be opened from the outside at this time.
Automatic recovery principle: when the door is closed again, the lock tongue 13 moves inwards the lock body 4 due to the force given by the lock catch box 9 and the lock catch plate 10, so that the linkage plate 15 is driven to move, the stop plate 16 is pushed to exit the installation groove 1905 of the square core, the square core is reinserted into the square core hole of the outer handle under the action of the first spring 5, the handle lock is restored to a general state, and at the moment, a user can open the door by rotating the inner handle and the outer handle.
Installation requirements
1. As shown in fig. 1 to 3, the square core 19 is inserted into the square core hole of the outer handle 2.
2. The abnormal working state means that the square core 19 is separated from the square core hole of the outer handle 2, namely, the door can be opened only by rotating the inner handle 12, and the door can not be opened by rotating the outer handle 2.
3. The inner handle 12 is welded to the square core 19 as a unit and is movable back and forth together with respect to the inner panel.
4. The lock tongue 13 and the interlocking plate 15 are welded into a whole and can move up and down together relative to the positioning plate 14.
5. The spring retainer 6 is threadedly connected to the square core 19 to secure the first spring 5, the first spring 5 being placed in compression by rotating the spring retainer 6 so that there is a tendency for the inner handle and square core to move toward the outer panel member.
6. The positioning plate 14 is similar to a portal structure, two rectangular holes are formed in the lock shell 21, and the positioning plate 14 is only required to be inserted into the two holes when being installed; in general, the positioning plate 14 can prevent the movement of the lock tongue 13 and the linkage plate 15, and further prevent the rotation of the transmission member 20, and further prevent the rotation of the square core 19, so that the inner handle maintains the state shown in the figure.
When the outer handle is installed, the protruding part in the outer panel 1 needs to be ensured to be just inserted into the groove at the front end of the outer handle 2, so that the outer handle 2 can only rotate 90 degrees; when the coil spring 22 is installed, it is necessary to ensure that the outer handle has a tendency to rotate clockwise, so that in a general case, the outer handle maintains the state shown in the figure, thereby ensuring smooth progress of the automatic return process; the end cover 3 is in threaded connection with the outer handle 2 to prevent the outward movement of the coil spring 22.
