The present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 6, a lock body includes a clutch cover 1, an outer clutch block 4 and an inner clutch block 5. The inner wall of the clutch cover 1 is provided with a first boss 16, and the outer clutch block 4 is provided with a first boss 16. A groove 43, the first boss 16 is placed in the first groove 43; the outer clutch block 4 is provided with a slot 42, and the side wall of the clutch casing 4 is provided with a clutch pin hole 19, and the clutch pin hole 19 A clutch pin 3 that can be snapped into the card slot 42 is provided, and the inner clutch dial 5 is connected with the clutch outer casing 1 to drive the clutch outer casing 1 to rotate. The inner clutch paddle 5 is connected to the outer clutch paddle 4 through screws 6 . The lock body further includes a lock shell 300 , a deadbolt assembly 400 , a main deadbolt assembly 500 , a deadbolt push plate assembly 600 , a transmission plate assembly 700 and a drive mechanism 200 .

There are four states of the door: left outward opening, left inward opening, right outward opening, and right inward opening. The inner clutch dial 4 is driven to rotate by the handle inside the house, and the outer clutch dial 5 is driven to rotate by the handle outside the house. The handle inside the house can be locked by taking out the lock tongue by turning the handle up, and the lock tongue can be unlocked by pressing the handle down and turning; the handle outside the house can be locked by taking out the lock tongue by turning the handle up. Before it succeeded, it was idling when the handle was pressed down and turned, and the lock tongue could not be retracted to unlock.

Specifically, as shown in FIG. 2 , the clutch pin 3 is provided with a second step 31 , the clutch jacket 1 is provided with a first step 11 , and the clutch pin spring 2 on the clutch pin 3 is fitted into the clutch jacket 1 . The thin wall 12 provided on the clutch casing 1 can prevent the clutch pin 3 from being ejected, that is, the thin wall 12 is in the shape of a truncated cone.

As shown in FIG. 5 , the inner clutch block 5 is designed with a second boss 51 , the clutch casing 1 is symmetrically provided with second grooves 15 at both ends, and the second boss 51 is embedded in the second groove 15 , so that the inner clutch block 5 can drive the clutch jacket 1 to rotate unconditionally.

As shown in Figures 2 and 5, the outer clutch block 4 is provided with a threaded hole 44 and a third step 45, the inner clutch block 5 is provided with a through hole 52 and a fourth step 53, and the clutch jacket 1 is also provided with The fifth step 18 enables the outer clutch paddle 4 and the inner clutch paddle 5 to be fixed by clamping the clutch jacket 1 . Therefore, the screw 6 can be removed, so that the outer clutch block 4 and the inner clutch block 5 are detached from the clutch jacket 1 and fixed, and then the installation positions of the outer clutch block 4 and the inner clutch block 5 can be exchanged, and the internal and external replacement of the lock body can be realized. Towards. After the direction of the inner clutch paddle 5 and the outer clutch paddle 4 are changed, and because the second groove 15 and the first boss 16 designed on the clutch jacket 1 are symmetrically designed, the inner clutch paddle 5 and the outer clutch paddle 5 are symmetrically designed. The dial block 4 can still drive the clutch casing 1 to rotate.

As shown in Figures 3, 4 and 6, the clutch casing 1 is provided with a first boss 16 and a clutch pin hole 19 at a central position, and correspondingly, a first groove 43 is provided on the outer clutch paddle 4 and a Two vertically distributed card slots 42, the first boss 16 is completely embedded in the first groove 43, so that after the outer clutch paddle 4 and the inner clutch paddle 5 are reversed, the outer clutch paddle 4 and the clutch pad The relative position of the casing 1 remains unchanged, that is, the boss 16 is completely embedded in the first groove 43 , and the clutch pin hole 19 is also completely located in the groove 42 .

When the outer clutch block 4 rotates counterclockwise, the first boss 16 is in contact with the first groove 43. At this time, the outer clutch block 4 can unconditionally drive the clutch jacket 1 to rotate, that is, to achieve outdoor By lifting the handle and turning the handle, the lock tongue can be brought out for locking action. However, when the outer clutch block 4 rotates clockwise, there is a certain distance between the first groove 43 and the first boss 16 because there is no contact between the first groove 43 and the first boss 16, so the outer clutch block 4 cannot drive the clutch jacket when it rotates. 1. Rotate, that is, when the handle is pressed down, it is idling. When the clutch pin 3 is pushed by the driving mechanism 200 , the clutch pin spring 2 will be compressed so that the clutch pin 3 extends into the slot 42 of the outer clutch block 4 , so that the outer clutch block 4 can be driven when it rotates clockwise. The clutch cover 1 is rotated, that is, the outdoor user verification is successful, and the lock tongue can be retracted to unlock by pressing the handle down to rotate. When the driving mechanism 200 rotates and no longer presses the clutch pin 3 , the clutch pin 3 leaves the clamping slot 42 under the elastic force of the clutch pin spring 2 .

As shown in FIG. 7 , the lock shell 300 is composed of an inner shell and an outer shell. Both the inner shell and the outer shell are provided with first protrusions 3001 distributed in an annular array, and three evenly distributed along the center of the circular hole. Both ends of the clutch casing 1 are provided with circular rings 17 , and the circular rings 17 are in contact with the first protrusions 3001 . During installation, the clutch housing 1 is restricted to rotate in the middle of the lock housing 300 . In this way, when the outer clutch block 4 and the inner clutch block 5 are removed, the clutch cover 1 can be kept in the middle of the lock housing 300 without being moved. In addition, the lock shell 300 is provided with a third groove 3002, which can limit the rotation angle of the outer clutch dial 4 when it cooperates with the outer clutch dial 4, so as to prevent the first groove 43 of the outer clutch dial sleeve 4 from colliding with the clutch. The first bosses 16 of the casing 1 cannot come into contact beyond their clearance distance during rotation.

As shown in FIGS. 8-10 , this also includes a cam toggle plate 8 , an arc-shaped slot 82 is provided on the oblique tongue toggle plate 8 , a third boss 20 is provided on the clutch casing 1 , and the third boss 20 It is located in the annular slot 82 , and the oblique tongue toggle plate 8 is movably connected with the oblique tongue assembly 400 . Specifically, the oblique tongue toggle plate 8 is provided with a protruding end 81 and an arc-shaped slot 82, and a third boss 20 is provided on the clutch casing 1. The third boss 20 is only in contact with the arc-shaped slot 82 on one side, and the other is in contact with the arc-shaped slot 82. There is a large space on one side, so the clutch cover 1 can only drive the oblique tongue toggle plate to rotate when the handle is pressed down in the direction of rotation. plate rotates. The protruding end 81 of the oblique tongue toggle plate 8 is in contact with the oblique tongue moving plate 4001 provided on the oblique tongue assembly 400, so that the oblique tongue toggle plate 8 will drive the oblique tongue moving plate when rotating, thereby driving the entire oblique tongue. components to move.
