Summary of the invention

[0003] The invention solves the problem that the buttons of the existing push-type lock are arranged on the surface of the lock, resulting in poor aesthetics and layering of the lock.

[0004] The technical solution adopted by the present invention is a button hidden lock, including a large handle, in which a button, a first sliding part and a second sliding part are arranged, the button is arranged on one side of the first sliding part and the second sliding part is arranged on the other side, the other end of the button extends to the outside of the large handle, and the other end of the second sliding part extends to the outside of the large handle, and the button, the first sliding part and the second sliding part are all movably connected to the large handle by a pin.

[0005] Furthermore, the large handle includes a first mounting portion, a second mounting portion and a handle, one end of the handle is connected to the first mounting portion and the other end is connected to the second mounting portion to form an enclosure space for the button, and one end of the button extends into the enclosure space.

[0006] Furthermore, a pressing block is provided in the large handle.

[0007] Furthermore, positioning blocks are arranged opposite to each other in the pressing block, and a movable slot is formed between the two opposite positioning blocks.

[0008] Furthermore, a clutch is provided in the large handle, and one end of the second sliding member passes through the clutch and extends to the outside of the large handle.

[0009] The beneficial effects of the present invention compared with the prior art are as follows: the button is arranged in the enclosure space of the large handle. When the door needs to be opened, the large handle can be pulled while the button can be pressed to control the lock to unlock.

[0015] like Figures 1 to 4 A button hidden lock comprises a large handle 10, in which a button 11, a first sliding member 12 and a second sliding member 13 are provided. The button 11 is provided on one side of the first sliding member 12 and the second sliding member 13 is provided on the other side. The other end of the button 11 extends to the outside of the large handle 10, and the other end of the second sliding member 13 extends to the outside of the large handle 10. The button 11, the first sliding member 12 and the second sliding member 13 are all movably connected to the large handle 10 through a pin 14.

[0016] When in use, the large handle 10 is fixed to the door leaf, and the end of the second sliding member 13 extending to the outside of the large handle 10 is connected to the lock core. When unlocking is required, the button 11 on the outside of the large handle 10 is pressed so that its pushing end pushes the first sliding member 12 to swing, and the other end of the first sliding member 12 pushes the second sliding member 13 to swing its end, thereby driving the components of the lock core to work together to unlock.

[0017] The large handle 10 includes a first mounting portion 101, a second mounting portion 102 and a handle 103. One end of the handle 103 is connected to the first mounting portion 101 and the other end is connected to the second mounting portion 102 to form an enclosure space 104 for the button 11. One end of the button 11 extends into the enclosure space 104. When in use, the first mounting portion 101 and the second mounting portion 102 are installed with the door leaf through a connecting component. The button 11 is arranged in the enclosure space 104. The handle 103 can cover the button 11 to achieve a hidden structure, making the lock more beautiful as a whole.

[0018] The large handle 10 is provided with a pressing block 15, and a positioning block 151 is relatively provided in the pressing block 15. A movable groove is formed between the two relatively positioning blocks 151. When the first sliding member 12 pushes the second sliding member 13 to swing, one end of the second sliding member 13 moves up and down in the movable groove. The pressing block 15 can prevent the second sliding member 13 from shifting when swinging.

[0019] The large handle 10 is further provided with a clutch 16 , and one end of the second sliding member 13 passes through the clutch 16 and extends to the outside of the large handle 10 .

[0020] To sum up, in the button hidden lock of the present invention, the button 11 is arranged in the enclosure space 104 of the large handle 10. When the door needs to be opened, the large handle 10 can be pulled and the button 11 can be pressed to control the lock to unlock. The large handle 10 can cover the button 11 to realize a hidden structure, making the lock more beautiful as a whole.
