Below in conjunction with accompanying drawing, the utility model is set forth in further detail.

As shown in FIG. 1 , the utility model includes a shell structure 1 , a transmission structure 2 and a dead bolt 3 .

The casing structure 1 includes a cylinder body 11 , a composite plate 12 , a driving wheel 13 and a limiting plate 15 . The cylinder body 11 is a hollow body for accommodating the transmission group 2 and the dead bolt 3 , and the driving wheel 13 is provided with claws 14 . The combination plate 12 is extended to the bottom of the cylinder body 11 . As shown in FIG. 2 , the combined plate 12 is combined with the driving wheel 13 .

The transmission group 2 includes a latch plate 21 , an anti-theft plate 22 , a latch release plate 23 and a safety lever 24 . One end of the latch plate 21 is provided with a hook head 211 . The other end of the latch plate 21 is provided with more than one set of driving teeth 212 corresponding to the claws 14 of the driving wheel 13 . The anti-theft plate 22 is provided with a stopper 221 that is inclined to one side and connected by a curved portion 222 . One end of the anti-theft plate 22 is connected to the inner bottom of the cylinder body 11 . One end of the unlocking plate 23 is provided with a hook 231 , and the other end is provided with an abutting foot 232 capable of pressing against the curved portion 222 of the anti-theft plate 22 . The safety lever 24 is clamped on the hook 231 at one end of the latch release plate 23, and is attached to the dead bolt 3. An elastic element 25 is arranged between the safety lever 24 and the latch plate 21, so that the safety lever 24 is always facing outwards. Stretch stretch.

The bolt 3 includes a bolt head 31 , a bolt plate 32 , a reinforcement plate 33 and an elastic element 34 . The locking tongue 31 has a hole 311 and a side hole 312 communicating with the hole 311 . A protrusion 321 and a slot 322 are formed on the latch plate 32 . The hole 311 on the deadbolt head 31 is for one end of the deadbolt plate 32 to extend into, and the side hole 312 is for the projection 321 on the deadbolt plate 32 to snap in, so that the deadbolt head 31 and the deadbolt plate 32 are combined and in a linked state . In order to make the deadbolt plate 32 and the deadbolt head 31 can be easily combined and have a better positioning effect, after the deadbolt plate 32 is inserted into the hole 311 of the deadbolt head 31, a reinforcing plate 33 is filled in the gap between the two, and The external force is inserted and fixed in a tight fit, so that the reinforcement plate 33 and the deadbolt plate 32 will not fall off, and the combination of the two can withstand a large external force, preventing the deadbolt 31 and the deadbolt plate 32 from The joint between them is bent and deformed by impact. The elastic element 34 is placed between the locking tongue 31 and the inner bottom of the barrel 11 , so that the locking tongue 31 has a constant elastic force extending out of the restricting plate 15 . The dead bolt plate 32 is combined in the side hole 312 of the dead bolt head 31 with the protrusion 321 at one end thereof, and is hooked on the hook head 211 of the latch plate 21 with the slot hole 322 on it, so that the latch plate 21 can indirectly drive Dead bolt 31 actions.

The drive shaft of the lockset drives the driving wheel 13 for positioning rotation, and the driving wheel 13 presses the latch plate 21 to drive the teeth 212 with its upper claws 14, so that the latch plate 21 moves, and the latch tongue 31 can be drawn back by the latch plate 21.

The utility model device is in the door sheet 4. As shown in FIG. 2 , when the door piece 4 is in an open state, the locking tongue 31 and the bumper 21 protrude from the side end surface of the door piece 4 under the push of the elastic elements 34 and 25 .

As shown in Figure 3, when the door sheet 4 is locked on the door frame 41, the safety lever 24 is stopped by the door frame 41 and retreats inwardly. The anti-theft plate 22 is separated from the curved portion 222 of the anti-theft plate 22 to release the anti-theft plate 22, so that the stop pin 221 of the anti-theft plate 22 is biased into the moving range of the dead bolt 31 to prevent the dead bolt 31 from retracting, preventing The locking bolt is destroyed by pressing the locking tongue 31 and retracting, so as to achieve the anti-theft effect. A reinforcing plate 33 is provided between the locking tongue 31 and the locking tongue plate 32, so that the locking tongue 31 protruding out of the cylinder 11 can also bear a large external impact force without bending and deformation.

The deadbolt head 31 and the deadbolt plate 32 can be combined conveniently and firmly without loosening, and can withstand large external forces to prevent the joint between the deadbolt head 31 and the deadbolt plate 32 from being bent and deformed by impact.
