Detailed ways

Please refer to Fig. 2, Fig. 3, shown in Fig. 4, a kind of U-shaped lock rotating shaft structure of the present utility model, it is pivotally provided with a rotating shaft group 6 on one side end of a lock head body 5, and described rotating shaft group 6 is connected A U-shaped bar body 7, wherein:

The lock body 5 is provided with a lock hole 51 at one end, and a sleeve portion 52 at the other end, and a through hole 521 penetrates through the sleeve portion 52;

The shaft group 6 includes:

A sleeve 61, which runs through a through hole 611, and a set of joint holes 612, a first pin hole 613 and a shaft hole 614 are horizontally provided on the sleeve 61, so as to communicate with the through hole 611, the The socket hole 612 is used for inserting the socket portion 52 of the lock body 5 into the pivot joint;

An outer sleeve 62 is a hollow cylinder with a perforation 621 on its side;

A fixed head 63 is provided with a slot 631 for the second end 72 of the U-shaped rod body 7 to pass through, and a limiting groove 632 is provided on the bottom side of the slot 631, and the fixed head 63 is a There is a retaining edge 633 on the side;

A fixed bolt 64 is provided with a stop body 642 at one end of its rod body 641, and is provided with a second latch hole 643 on the rod body 41, and the second latch hole 643 is connected with the first latch hole of the sleeve 61 613 corresponds to a wedging pin A;

The first end 71 of the U-shaped rod body 7 is provided with a slot 711 for being inserted into the lock hole 51 of the lock head body 5, and the second end 72 of the U-shaped rod body 7 is provided with a through hole 721;

Through the composition of the above components, the socket portion 52 of the lock body 5 is inserted into the socket hole 612 on one side of the sleeve 61 during assembly, and the outer sleeve 62 is sleeved on the other side of the sleeve 61. side, align the perforation 621 with the shaft hole 614, insert the second end 72 of the U-shaped rod body 7 into the perforation 621 of the outer sleeve 62 and the shaft hole 614 of the sleeve 61, and then use the rod body 641 of the fixing bolt 64 Insert the through hole 611, the through hole 521, and the through hole 721, and wedge the pin A into the first pin hole 613 and the second pin hole 643, and then insert the fixed head 63 from the other side of the sleeve 61 into the Through hole 611, and insert the end of the rod body 641 of the fixed bolt 64 into the limit groove 632 of the fixed head 63 to complete its assembly; when locking, first turn the U-shaped rod body with the shaft group 6 as the axis 7.
