Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 As shown, a sliding door lock according to an embodiment of the present invention is applied to a door panel, a handle 8 is provided on the outside of the door panel, and the sliding door lock includes a handle device and a lock device;

[0027] The handle device includes a handle base 11, a key column 12, an unlocking piece 13, a pull-wire paddle 14 and a pull wire. The handle base 11 is arranged on the inner side of the door panel. The key column 12 is slidably connected to the handle base 11 along the inward and outward directions. The inner side of the key column 12 is used to abut against the unlocking piece 13. The middle part of the unlocking piece 13 is rotatably connected to the handle base 11. One end of the unlocking piece 13 abuts against one end of the pull-wire paddle 14. The middle part of the pull-wire paddle 14 is rotatably connected to the handle base 11.

[0028] The locking device is used to be arranged on the inner side of the door panel and is used to lock the door panel. The other end of the pull wire paddle 14 is transmission-connected to the locking device via the pull wire.

[0029] Specifically, the key column 12 has a locking function. A key is inserted into the keyhole on the outside of the key column 12. Once the key column 12 is locked, it cannot be pushed inward. By rotating the key 180 degrees to unlock the key column 12, the key column 12 can be pushed inward. Furthermore, the pull-wire paddle 14 is located inside the unlocking plate 13.

[0030] In this embodiment, after unlocking the key column 12, the key column 12 is pushed inward, and the key column 12 is used to abut against the unlocking plate 13, and the middle part of the unlocking plate 13 is rotated and connected to the handle base 11, thereby driving the unlocking plate 13 to rotate; the unlocking plate 13 is used to abut against the pull-wire paddle 14, and the middle part of the pull-wire paddle 14 is rotated and connected to the handle base 11, thereby driving the pull-wire paddle 14 to rotate; the pull-wire paddle 14 and the locking device are connected by a pull wire, thereby driving the locking device to unlock.

[0031] Therefore, by setting the handle device to a structure including a key column 12, an unlocking piece 13, a pull wire paddle 14 and a pull wire, the key column 12 is used to drive the unlocking piece 13, the pull wire paddle 14 and the pull wire in sequence, and the pull wire is used to drive the lock device to unlock. The lock device and the handle device are connected by a pull wire. When the lock device and the handle device are set at different positions of the door panel, the lock device can be unlocked more easily through the handle device.

[0032] Secondly, by providing the handle base 11 , it is convenient to assemble the unlocking piece 13 and the wire pulling piece 14 .

[0033] Alternatively, as Figure 1 and Figure 2 As shown, the other end of the unlocking piece 13 extends outside the outline of the handle base 11.

[0034] In this embodiment, by extending the other end of the unlocking piece 13 to the outside of the contour of the handle base 11, since the unlocking piece 13 is located on the inner side of the door panel, that is, inside the door, the user can directly act on the other end of the unlocking piece 13 to drive the unlocking piece 13 to rotate, thereby utilizing the unlocking piece 13 to drive the pull wire paddle 14 and the pull wire in turn to unlock the locking device.

[0035] Secondly, after unlocking the key column 12 outside the door, the key column 12 can be pressed to drive the unlocking piece 13 to rotate, so that the unlocking piece 13 can drive the pull wire paddle 14 and the pull wire in turn to unlock the lock device.

[0036] Alternatively, as Figure 1 and Figure 2 As shown, a first connecting plate 3 is provided on the handle base 11 , and a first wire drawing groove 31 is opened on the first connecting plate 3 , and the wire passes through the first wire drawing groove 31 .

[0037] Specifically, the first connecting plate 3 is provided with a first docking hole in the radial direction of the first wire drawing groove 31 , and the wire is passed through the first docking hole and then arranged in the first wire drawing groove 31 .

[0038] In this embodiment, by setting up a first connecting plate 3 and opening a first wire groove 31 on the first connecting plate 3, the wire can be positioned by passing the wire through the first wire groove 31, ensuring that the wire can be easily connected to the locking device after passing through the first connecting hole 51.

[0039] Alternatively, as Figure 2 As shown, one end of the pull wire paddle 14 is provided with a contact piece 4, and the contact piece 4 is located on the inner side of the unlocking piece 13 and is used to abut against the unlocking piece 13. The other end of the pull wire paddle 14 is provided with a connecting piece 5, and the connecting piece 5 is used to connect the pull wire.

[0040] Specifically, when the wire pull tab 14 is positioned above the unlocking tab 13, the lower end of the wire pull tab 14 is provided with an abutting tab 4, and the upper end of the wire pull tab 14 is provided with a connecting tab 5. When the wire pull tab 14 is positioned below the unlocking tab 13, the upper end of the wire pull tab 14 is provided with an abutting tab 4, and the lower end of the wire pull tab 14 is provided with a connecting tab 5. Furthermore, the connecting tab 5 defines a first fixing hole 52, into which one end of the wire is connected.

[0041] In this embodiment, the pull-wire paddle 14 is disposed at the upper end of the unlocking plate 13. The unlocking plate 13 is rotatably connected to the handle base 11 via a first movable shaft, the axial direction of the first movable shaft being vertically oriented. The pull-wire paddle 14 is rotatably connected to the handle base 11 via a second movable shaft, the axial direction of the second movable shaft being oriented horizontally. The left end of the unlocking plate 13 is grounded to the abutment plate 4, and the right end of the unlocking plate 13 extends beyond the contour of the handle base 11. The rotation of the unlocking plate 13 pushes the lower end of the abutment plate 4 inward, thereby driving the pull-wire paddle 14 to rotate, causing the connecting plate 5 to move outward, thereby pulling the pull wire to unlock the locking device.

[0042] Alternatively, as Figure 1 and Figure 2 As shown, the handle device also includes a spring, a first connecting hole 51 is opened on the connecting plate 5, a second connecting hole 32 is opened on the first connecting plate 3, one end of the spring is connected to the first connecting hole 51, and the other end of the spring is connected to the second connecting hole 32.

[0043] In this embodiment, a spring is provided, a first connection hole 51 is formed on the connecting plate 5, and a second connection hole 32 is formed on the first connecting plate 3, with both ends of the spring connected to the first connection hole 51 and the second connection hole 32, respectively. When the pull-wire paddle 14 rotates and the pull wire is pulled to unlock the locking device, the spring can drive the pull-wire paddle 14 to rotate in the opposite direction, driving the pull wire to return to its original position.

[0044] Alternatively, as Figure 3 and Figure 4 As shown, the lock device includes a lock base 21, a lock paddle 22, a lock 23 and a locking column 24. The lock base 21 is used to be set on the inner side of the door panel, and the middle part of the lock paddle 22 is rotatably connected to the lock base 21. One end of the lock paddle 22 is connected to the pull wire, and the other end of the lock paddle 22 is used to abut against one end of the lock 23. The middle part of the lock 23 is rotatably connected to the lock base 21, and the locking column 24 is set on the lock base 21. The other end of the lock 23 is used to limit the locking column 24.

[0045] Specifically, a second fixing hole 221 is defined on the lock paddle 22 , and the other end of the pull wire is connected to the second fixing hole 221 .

[0046] In this embodiment, the pull wire paddle 14 and the lock paddle 22 are connected by a pull wire. The pull wire paddle 14 rotates to drive the pull wire, and the lock paddle 22 is driven to rotate by the pull wire. During the rotation of the lock paddle 22, the lock 23 is driven to rotate, so that the lock 23 is separated from the locking column 24, thereby achieving unlocking.

[0047] Alternatively, as Figure 3 As shown, a second connecting plate 6 is provided on the lock base 21 , and a second wire drawing groove 61 is opened on the second connecting plate 6 , and the wire passes through the second wire drawing groove 61 .

[0048] Specifically, the second connecting plate 6 is provided with a second docking hole in the radial direction of the second wire pulling groove 61 , and the pulling wire passes through the second docking hole and is then arranged in the second wire pulling groove 61 .

[0049] In this embodiment, by setting a second connecting plate 6 and opening a second wire drawing groove 61 on the second connecting plate 6, the wire drawing can be positioned by passing the wire through the second wire drawing groove 61, ensuring that the wire drawing can be more easily connected to the lock paddle 22 after passing through the second wire drawing groove 61.

[0050] Alternatively, as Figure 3 As shown, the locking device also includes a limit plate 7, one side of the lock base 21 is open, the lock paddle 22, the lock 23 and the locking column 24 are all set from the opening to the lock base 21, and the limit plate 7 is used to be set at the opening and connected to the lock base 21.

[0051] In this embodiment, an opening is provided on the lock base 21, so that the lock paddle 22, the lock buckle 23, and the locking post 24 can be easily installed on the lock base 21 through the opening. A limiting plate 7 is provided at the opening to limit the lock paddle 22, the lock buckle 23, and the locking post 24, thereby preventing the lock paddle 22, the lock buckle 23, and the locking post 24 from being separated from the lock base 21.

[0052] Optionally, two locking devices are provided on the door panel, and the upper and lower ends of the unlocking piece 13 are provided with the pull wire paddles 14, and the two pull wire paddles 14 are connected to the two locking devices one by one through pull wires.

[0053] Specifically, if Figure 2 As shown, first connecting plates 3 are provided at both upper and lower ends of the handle base 11 .

[0054] In this embodiment, two locking devices are provided, and pull-wire paddles 14 are provided at the upper and lower ends of the unlocking piece 13.
