[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1-5 As one embodiment of this utility model, a square sliding door lock is disclosed. Specifically, the sliding door lock includes a lock frame 1 and a lock tongue 2 placed in the lock frame 1. Of course, in this embodiment, the lock frame 1 is generally square in shape and is installed on the side of the sliding door.

[0030] The front end of the lock frame 1 has a clearance opening 10 for the latch 2 to flip out. When closing the door, the sliding door is slid close to the door frame. At this time, by flipping the latch 2 outward along the clearance opening 10, the latch 2 and the locking rod inside the door frame are engaged. This can limit the lateral movement of the door. Inside the lock frame 1, a handle assembly 3 for driving the latch 2 to rotate is also installed.

[0031] The front end of the lock frame 1 is also rotatably connected to a handle 4.

[0032] In other words, the sliding door lock of this utility model, in addition to realizing the function of closing the sliding door by rotating the bolt 2 through the handle assembly 3, can also realize the lateral movement of the sliding door by pulling the handle 4 during the process of pulling the sliding door, thus solving the problem of inconvenience in closing the door in the case of hidden sliding door installation, where the edge of the sliding door is not easy to hold.

[0033] In some embodiments, the lock frame 1 of the present invention includes two side plates 11 and a panel frame 12 disposed between the two side plates 11. Specifically, in this embodiment, the side plates 11 are L-shaped and the two side plates 11 are symmetrically distributed. The clearance opening 10 is formed on the panel frame 12.

[0034] The side plate 11 and the panel frame 12 are connected and fixed by fasteners 13. Of course, in this embodiment, the fasteners 13 can be bolts. The two side plates 11 are fixed to the panel frame 12 by two bolts to achieve the assembly and forming of the entire lock frame 1.

[0035] In addition, the handle assembly 3 in this embodiment includes two corner pieces 31 symmetrically distributed on both sides of the latch 2, and the corner pieces 31 are also L-shaped structural components;

[0036] A knob 32 is connected to the side of the corner piece 31, and a groove 33 is provided on the end face of the corner piece 31. The groove 33 and the rotating shaft 20 of the latch 2 are connected and cooperate. That is, in this embodiment, the rotation of the corner piece 31 is controlled by rotating the knob 32, and the rotation of the latch 2 is controlled by rotating the corner piece 31. The opening of the groove 33 allows the entire latch 2 to have a certain amount of movement to ensure that it can be engaged with the locking rod on the door frame.

[0037] Based on the above embodiments, in this embodiment, the knob 32 and the corner piece 31 are inserted together, and a locking pin 34 is provided between the knob 32 and the corner piece 31. A gasket 35 is also fitted onto the outside of the knob 32. Specifically, in this embodiment, the knob 32 includes a handle portion and a sleeve portion, and the sleeve portion and the corner piece 31 are inserted together. Figure 2 As shown, in this embodiment, through holes are provided on the end faces of both the sleeve and the corner piece 31. The locking pin 34 is inserted between the through holes of the sleeve and the corner piece 31 to lock them circumferentially. In this embodiment, the locking pin 34 is a U-shaped locking pin, and its two ends can be bent. Its specific usage is a conventional method for those skilled in the art, and will not be described in detail here.

[0038] Furthermore, in this embodiment, the end face of the side plate 11 has a recessed position 14 that is recessed towards the side of the latch 2. The handle portion of the knob 32 is placed in the recessed position 14. The gasket 35 abuts against the inner wall of the recessed position 14 and the locking pin 34. The gasket 35 is used to laterally limit the knob 32. With the support of the gasket 35, the installation stability of the knob 32 is greatly improved. The design of the recessed position 14 provides an installation space for the knob 32. At the same time, since the knob 32 is installed in the recessed position 14, the overall external dimensions can be saved, thus achieving a more aesthetically pleasing structural design.

[0039] In some embodiments, the end face of the panel frame 12 of the present invention is recessed towards the center of the door lock to form a mounting position 15. The handle 4 is rotatably connected to the mounting position 15 via a shaft 41. It should be noted that when the handle 4 is in the retracted state, its outer side is flush with the outer side of the panel frame 12 to avoid interference with the closing of the movement, while ensuring the overall aesthetics.

[0040] The handle 4 is L-shaped, and a slotted hole 42 for the latch 2 to pass through is provided in the middle of the handle 4. In addition, the shaft 41 rotates in the upper part of the back side of the handle 4. When the handle 4 is needed to pull the sliding door, it can be touched to the upper side of the handle 4 to make it rotate, and then the lower part of the handle 4 can be pulled to make it fully exposed. Then, the handle 4 can be held to move the sliding door horizontally.

[0041] Preferably, in this embodiment, a stop shaft 16 is also fixed in the middle of the panel frame 12. The stop shaft 16 passes through the clearance opening 10 to stop the maximum rotation angle of the latch 2. The maximum angle is the maximum angle after the latch 2 flips outward. That is, when the latch 2 flips outward and touches the stop shaft 16, it cannot rotate further.

[0042] It should be noted that the latch 2 includes a triangular portion 21 and a hook portion 22 formed at the top of the triangular portion 21, and the handle assembly 3 is connected to the triangular portion 21.

[0043] The bottom of the triangular part 21 also has a stop notch 23. Specifically, the stop notch 23 is used to cooperate with the stop shaft 16 mentioned above. That is, when the latch 2 rotates outward and flips, it stops rotating when the stop notch 23 at its bottom abuts against the stop shaft 16. Conversely, when unlocking is required, the knob 32 is turned in the opposite direction until the latch 2 is reversed and retracted and stays inside the entire door lock, thus completing the unlocking and retraction of the latch 2.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
