[0017] 31 - square core, 32 - reversing gear lever, 41 - guide groove, 42 - square groove, 71 - small latch. CONCRETE IMPLEMENTATIONS
[0018] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0019] Combining Figs. 1 to 3 The lock tongue structure of the partition lock shown comprises a lock body shell 1 and a rotating handle 2 connected, the inside of the lock body shell 1 is provided with a reversing core 3, the side surface of the reversing core 3 is provided with a telescopic piece core 4, the side surface of the telescopic piece core 4 is provided with an arc limit board 5, the inside of the arc limit board 5 is provided with a spring 6, one end of the telescopic piece core 4 is provided with a lock tongue 7, the lock tongue 7 is connected with the telescopic piece core 4 through a screw, one end of the lock body shell 1 is provided with an opening, the lock tongue 7 is located inside the opening, and the two side surfaces of the lock tongue 7 can be connected with the telescopic piece core 4.
[0020] The inside surface of the reversing core 3 is fixedly provided with a square core 31, the square core 31 is inserted into the inside of the handle 2 and is fastened through a screw, the inside surface of one end of the reversing core 3 is provided with a reversing gear lever 32 and is connected through a rotating shaft, and the reversing core 3 is connected with the lock body shell 1 through a rotating shaft.
