[0020] like Figure 5 As shown, the specific structure of the password component 24 includes a locking wheel 241, a password wheel 242 and an adjusting wheel 243; the interiors of the locking wheel 241 and the adjusting wheel 243 are movably connected to the exterior of the fixed sleeve 21, the exteriors of the locking wheel 241 and the adjusting wheel 243 are movably connected to the password wheel 242, and the interiors of the locking wheel 241 and the adjusting wheel 243 are provided with card slots, and the card slots are connected to the convex grooves 26.

[0021] A T-shaped lock groove is provided inside the other side of the bottom of the lock housing 1; and a T-shaped lock hole block is provided on the other side of the folding lock strip 4.

[0022] The use state of the utility model is as follows: the utility model has a reasonable and simple structure, low production cost, convenient installation, and complete functions. When locking, first unfold the folding lock strip 4, and then embed the T-shaped lock hole block on the other side of the folding lock strip 4 into the T-shaped lock groove inside the other side of the lock head housing 1, and then press the unlocking cover 3 to make one end of the lock tongue 25 connected to the inside of the T-shaped lock hole block of the folding lock strip 4, and the card ball 29 is carded into the card hole 210 on the rear side of the fixed shaft sleeve 21 under the action of the spring 211 to prevent the lock tongue 25 from moving at will, and then randomly rotate the code wheel 242 in each code component 24, and the lock gate wheel 241 and the adjustment wheel 243 in each code component 24 pass through the card slot The lock tongue 25 is connected to the convex groove 26 on the front side of the lock tongue 25, and several password components 24 are arranged in sequence along the fixed shaft sleeve 21. The spring 1 22 between the leftmost password component 24 and the left inner side of the fixed shaft sleeve 21 is in a compressed state, providing a certain reset force for the overall structure. The rotation of the password wheel 242 drives the lock gate wheel 241 to rotate, so that the card slot can deviate from the convex groove 26 on the front side of the lock tongue 25, and the lock tongue 25 can be prevented from moving right to complete the locking. When unlocking, when the user rotates each password wheel 242 to the correct password position, the positions of the lock gate wheel 241 and the adjusting wheel 243 change accordingly, and then the unlocking cover 3 is pulled out, so that the convex groove 26 on the front side of the lock tongue 25 can be at each The lock wheel 241 and the adjusting wheel 243 move in the slots, which makes the convex groove 26 also move in the guide groove 23, and the lock tongue 25 moves in the center of the fixed shaft sleeve 21, overcoming the elastic force of the second spring 211, so that the card ball 29 is separated from the card hole 210 on the left and enters the card hole 210 on the right, thereby ensuring that the lock tongue 25 will not move around after being unlocked and affect the next use. When the lock tongue 25 is separated from the other side of the folding lock strip 4, the other side of the folding lock strip 4 can be removed. When it is necessary to reset the password, the unlocking cover 3 can only be pulled out in the unlocked state, and the pressing block 28 can be exposed only after the unlocking cover 3 is pulled out, thereby ensuring the security of resetting the password, and then the user presses The reset pressing block 28, the inner inclined surface of the reset pressing block 28 pushes the right inclined surface of the reset sliding sleeve 27, so that the reset sliding sleeve 27 moves to the left, and the left movement of the reset sliding sleeve 27 drives all the lock gate wheels 241 and the adjusting wheel 243 to move a distance to the left, so that the lock gate wheel 241 is separated from the password wheel 242, and then the password wheel 242 can be rotated as needed to reset the password. After the reset is completed, the reset pressing block 28 is released, thereby driving the lock gate wheel 241 to move right and clamp the password wheel 242, which ensures that the card slot inside the lock gate wheel 241 is convenient for the convex groove 26 on the front side of the lock tongue 25 to pass smoothly to complete the unlocking.
