It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The invention will be further described in the following with reference to specific embodiments thereof,

as shown in fig. 2-4, a two-way sliding door lock comprises: the lock comprises a lock shell 1, wherein an installation plate 11 is formed at one end of the lock shell 1; the lock rod 2 is positioned in the lock shell 1, a spring 21 is sleeved on the lock rod 2, and the spring 21 enables the lock rod 2 to have a tendency of extending out of the lock shell 1; the bolt 3 is connected to the lock rod 1 and can extend out of the lock shell 1 through the mounting plate 11, and a supporting surface 31 perpendicular to the mounting plate 11 and a pushing surface 32 inclined relative to the supporting surface 31 are formed on two sides of the bolt 3; the lock rod 2 is connected with two lock tongues 3 which are distributed up and down, and the lock tongues 3 at the upper ends and the support surfaces 31 and the pushing surfaces 32 on the lock tongues 3 at the lower ends face opposite directions. Specifically, the door plate provided with the sliding door lock is closed, the lock tongue 3 extends into the buckle box on the door frame to be fixed, and the sliding door lock can be directly opened through the sliding door plate. After the lock tongue 3 extends into the buckle box on the door frame, the support surface 31 on the lock tongue can be abutted against the inner wall of the buckle box to play a role in positioning and supporting, so that the door plate can be stably kept in a closed state and cannot easily shake; when the door panel is pushed, when the lock tongue 3 enters or leaves the buckle box on the door frame, the inclined pushing surface 32 on the lock tongue 3 enables the lock tongue 3 to rapidly move back towards the inside of the lock case 1 when being pushed, and enables the spring 21 sleeved on the lock rod 2 to be pressed, and the spring 21 rebounds after the lock tongue 3 is not pushed, so that the lock tongue 3 drives the lock rod 2 to move, and the lock tongue 3 extends out of the lock case 1 again. The lock tongue 3 realizes the function of the sliding door lock capable of opening the door in two directions through the pushing surface 32 which inclines towards the opposite direction, so that the door plate can be opened from two sides, and meanwhile, a supporting surface 31 which can be abutted against the side wall of the buckle box is reserved on the lock tongue 3, so that the position of the lock tongue 3 in the buckle box can be kept stable.

As shown in fig. 5, a connecting rod 22 parallel to the mounting plate 11 is formed on the lock lever 2, and the connecting rod 22 is cylindrical and is inserted into the latch 3 at both upper and lower ends. Specifically, the bolt 3 is inserted into the upper end and the lower end of the lock rod 2 through the connecting rod 22.

As shown in fig. 2 to 4, a supporting block 33 located in the lock case 1 is formed on the bolt 3, and one side of the supporting block 33 abuts against an end surface perpendicular to the mounting plate 11 in the lock case 1. Specifically, the supporting block 33 supports in the lock case 1, and can prevent the lock tongue 3 from overturning when being pushed to retract in the lock case 1, so that the lock tongue 3 can move stably.

As shown in fig. 1, 2 and 3, a guide block 34 facing one side of the lock case 1 is formed on the latch tongue 3, the latch tongue 3 at the upper end and the guide block 34 on the latch tongue 3 at the lower end face in opposite directions, guide holes 12 into which the guide blocks 34 are inserted are formed on both sides of the lock case 1, and the guide blocks 34 move along the guide holes 12. Specifically, in the moving process of the locking bolt 3, the guide block 34 can guide the locking bolt 3 along the guide hole 12, so that the locking bolt 3 is prevented from moving and deviating.

As shown in fig. 2-4, a rotatable lock core 4 is disposed in the lock housing 1, a lock hole 41 exposed outside the lock housing 1 and a lock block 42 disposed in the lock housing 1 are formed on the lock core 4, and the lock block 42 can abut against the rear end of the lock rod 2 along with the rotation of the lock core 4. Specifically, the sliding door lock can realize the functions of locking a door, unlocking and the like through the rotation of the lock cylinder 4, the using method is that a key is inserted into the lock hole 41 of the lock cylinder 4 to rotate, when the lock block 42 moves to the rear end of the lock rod 2 along with the rotation of the lock cylinder 4, the lock rod 2 is propped against by the lock block 42, the lock tongue 3 cannot be driven to return into the lock shell 1, and the sliding lock is locked; when the key inserted into the lock hole 41 is rotated again, so that the lock block 42 is removed from the rear end of the lock bar 2, the lock bar 2 can move normally, and the sliding door lock is in an unlocked state.

As a modified embodiment, a stop 13 is formed in the lock case 1 between the lock rod 2 and the lock cylinder 4, and the lock block 42 can abut against the stop 13 along with the rotation of the lock cylinder 4. Specifically, when the lock block 42 moves to the rear end of the lock rod 2, the stop block 13 can abut against the lower end of the lock block 42, so that a key inserted into the lock hole 41 can drive the lock cylinder 4 to further rotate, the lock block 42 leaves from the rear end of the lock rod 2, the rotation range of the lock cylinder 4 is effectively limited, the rotation direction of the key when the lock of the sliding door is controlled is determined, and the rotation direction of the key when the lock of the sliding door is locked is opposite to that when the lock of the sliding door is unlocked.

As shown in fig. 2 and 6, the lock block 42 is formed with a guide post 43, and the inner wall of the lock case 1 is formed with a guide rail 14, and the guide post 43 moves along the guide rail 14 with the rotation of the lock cylinder 4. Specifically, the guide post 43 moves along the guide rail 14 to limit and guide the rotation of the lock cylinder 4, so that not only the movement range of the lock cylinder 4 is limited, but also the lock cylinder 4 can stably rotate.

As a modified embodiment, a positioning column 15 is formed in the lock case 1, and a torsion spring 5 is connected between the guiding column 15 and the positioning column 43. Specifically, the torsion spring 5 deforms and moves along with the movement of the positioning column 43, and the position of the positioning column 15 after the movement is fixed, so that the lock cylinder 4 can be kept in a stable state after the rotation, namely, the lock of the sliding door can be kept stable when being locked or unlocked.

As shown in fig. 2-4, a support plate 6 is formed in the lock housing 1, a support groove 61 is formed on the support plate 6, and the lock rod 2 abuts against the support groove 61 and passes through the support plate 6. Specifically, the support plate 6 guides the movement of the lock lever 2 through the support groove 61, and the movement of the lock lever 2 is performed along the support groove 61.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
