As shown in fig. 1, 11, 12 and 13, which are schematic views of the outdoor opening state of the clutch type door lock body according to the present invention, as shown in fig. 1, the door is fixed by the first arresting bolt 14 before the door is opened, the outer handle connecting piece 19 and the arresting disc 20 are fixed by the clutch shaft 21, and the ends of the lock tongue 5, the upper latch pin linkage hook 7 and the lower latch pin linkage hook 8 are inserted into the door frame before the door is opened indoors, so that the door is in a locked state; as shown in FIG. 11, when the key is inserted into the lock head 3, the pull guide 4 can be rotated to drive the pull hook 13 to make the stop bolt 14 leave the outer handle coupling member 19, but the clutch shaft 21 is still arranged in the outer handle coupling member 19 and the stop disk 20 to make the outer handle coupling member 19 and the stop disk 20 in an integral state; as shown in fig. 11 and 12, the outer handle 17 is twisted to drive the latch plate 20 integrated with the outer handle coupling member 19, so that the latch pulling rod 10 is driven by the latch pulling arm 23 of the latch plate 20 to move the latch 5 away from the door frame and thus to be pushed into the lock case 2; meanwhile, the bolt linkage hook column 11 on the bolt 5 drives the upper bolt linkage hook 7 and the lower bolt linkage hook 8 to leave the door frame and return to the inside of the door plate, so that the door can be opened. As shown in fig. 4, 6, 7 and 13, after the door is opened, the second outer detent bolt hole 38 of the outer handle coupling member 19 is driven to the end of the first detent bolt 14, because the elastic coefficient of the first spring 53 is greater than that of the second spring 56, one end of the clutch shaft 21 exits the second outer detent bolt hole 38 and the other end enters the inner detent bolt hole 42, at this time, after the first detent bolt 14 enters the second outer detent bolt hole 38, the outer handle coupling member 19 of the outer handle 17 is fixed by the first detent bolt 14; the inner handle coupling member 18 and the stop disk 20 are fixed by a clutch shaft 21; at the same time, the second stop bolt 15 exits the inner stop bolt hole 42 of the inner handle coupling member 18 and completely enters the second stop hole 29.
Fig. 14 is a schematic view showing the door closing state of the clutch type door lock body chamber according to the present invention. When the door is opened outdoors and a person enters the room, the inner handle connecting piece 18 and the stop disc 20 are in a fixed state through the clutch shaft 21, so that the inner handle 16 is rotated, the bolt pulling arm 23 on the stop disc 20 drives the bolt traction column 10 to push the bolt 5 into the door frame from the lock box 2; the second stop bolt 15 exits the inner stop bolt hole 42 in the inner handle connecting piece 18 and completely enters the second stop hole 29; meanwhile, the bolt linkage hook column 11 on the bolt 5 drives the upper bolt linkage hook 7 and the lower bolt linkage hook 8 to be pushed into the door frame from the door plate, so that the door can be closed indoors.
Fig. 15 is a schematic view showing a state after the door is opened in the room according to the present invention. After the door is closed indoors, the stop bolt I14 is still inserted into the outer stop bolt hole II 38 on the outer handle connecting piece 19, namely, the outer handle connecting piece 19 and the fixed piece 12 are in a fixed state by the stop bolt I14, namely, the outer handle 17 outside the door cannot be rotated by hands at the moment; the inner handle coupling member 18 and the stop disk 20 are fixed by the clutch shaft 21, that is, the inner handle 16 is rotated by hand to determine whether the bolt 5 enters or exits the door frame, that is, a person rotates the inner handle 16 indoors to determine whether the door is opened or closed. When the inner handle 16 is rotated, the tongue pulling arm 23 on the stopping disc 20 drives the tongue pulling column 10 to withdraw the tongue 5 from the door frame into the lock box 2, and simultaneously, the bolt linkage hook column 11 on the tongue 5 drives the upper bolt linkage hook 7 and the lower bolt linkage hook 8 to withdraw from the door frame into the door panel, so that the indoor door opening can be realized.
Fig. 16 is a schematic view of the lock body structure after the push button is pressed when the user goes out. When the thumb presses the button 46 when the inner handle 16 is rotated, the push column 48 pushes the clutch shaft 21 into the second outer stop bolt hole 38 on the outer handle coupling member 19, and the clutch shaft 21 enters the second outer stop bolt hole 38 to fix the outer handle coupling member 19 of the outer handle 17 and the stop disk 20; the inner handle coupling member 18 and the stop disk 20 are fixed by the clutch shaft 21, and the second stop bolt 15 enters the inner stop bolt hole 42 on the inner handle coupling member 18, so that the inner handle coupling member 18 and the fixing member 12 are fixed by the second stop bolt 15.
Fig. 16 and fig. 1 are schematic views illustrating the door closing state of the clutch type door lock body according to the present invention. Before the outdoor door is closed, the outer handle connecting piece 19 is in a fixed state with the stop disc 20 through the clutch shaft 21, at the moment, the end parts of the lock tongue 5, the upper bolt linkage hook 7 and the lower bolt linkage hook 8 are all withdrawn from the door frame to enable the door to be in an opened state, so that the outer handle 17 can be twisted to drive the stop disc 20 integrated with the outer handle connecting piece 19, the bolt pulling arm 23 on the stop disc 20 drives the lock tongue traction column 10 to push the lock tongue 5 into the door frame, and meanwhile, the bolt linkage hook column 11 on the lock tongue 5 drives the upper bolt linkage hook 7 and the lower bolt linkage hook 8 into the door frame, so that the door can be closed; meanwhile, the inner end of the stop bolt I14 extends into the outer stop bolt hole II 37 on the outer handle connecting piece 19 under the elastic force of the spring I53, so that the outer handle 17 is fixed on the fixing piece 12 by the stop bolt I14. Therefore, the door can be reversely locked only by rotating the outer handle 17 along with the key without reversely locking the door by the key from the indoor door opening to the outdoor door closing, and the outer handle 17 is fixed on the fixing piece 12 along with the passive bolt I14 after the door is reversely locked, so that the outdoor door opening method can be repeated only by the key if the door is opened.
Therefore, the advantage of this embodiment is that people only need to rotate the inner handle 16 or the outer handle 17 to realize the effect of locking the door, and the conventional method of locking the door only by using a key is avoided, so that the door is time-saving and labor-saving.
