Please refer to fig. 5, one end of the locking block 7 is inserted into the clutch block 6 and locked with the clutch block 6, and the other end of the locking block 7 is provided with a locking hole 71, it should be noted that the locking hole 71 is a special-shaped hole, the locking hole 71 includes a large hole for the free end of the locking rope 2 to pass through, the hole wall of the large hole is provided with a small hole, and the small hole is mainly used for clamping an annular groove at the free end of the locking rope 2, so that locking and unlocking of the locking rope 2 are realized through movement of the locking block 7.
Please refer to fig. 5, in order to implement locking between the clutch block 6 and the lock block 7, the movement of the lock block 7 can be limited in a state that the clutch block 6 does not rotate, in a state that the clutch block 6 rotates, the rotation movement of the clutch block 6 can be converted into the horizontal movement of the lock block 7, two curve grooves 72 are formed at one end of the lock block 7 inserted into the clutch block 6, and a projection 61 inserted into the curve groove 72 is formed on the inner wall of the clutch block 6, and it should be noted that the track of the curve groove 72 is set as long as the clutch block 6 can be rotated to drive the lock block 7 to move horizontally, so that the lock rope 2 can be separated from the lock hole 71. It should be noted that the clutch block 6 may be provided with a curved groove 72, and the lock block 7 may be provided with a projection 61 for locking and sliding engagement. When the lock is unlocked, the clutch block 6 rotates, the convex block 61 of the clutch block 6 abuts against the curve groove 72 of the lock block 7 and pushes the lock block 7 to move, and the rotation motion of the clutch block 6 is converted into the horizontal motion of the lock block 7, so that the lock block 7 moves towards the unlocking direction; when locking, the lug 61 is inserted into the end of the curved slot 72, the clutch block 6 cannot rotate, and the curved slot 72 can lock the locking block 7 to move towards the unlocking direction, namely, the locking block 7 is limited to move in the horizontal direction. In addition, in order to make the returning of the locking piece 7 smoother, in combination with fig. 5 and 3, the coded padlock is provided with a reset piece for driving the locking piece 7 to move towards the locking direction, the reset piece is a reset spring 8, one end of the reset spring 8 abuts against the lock shell 1, and the other end abuts against the lock shell 1, so that the locking piece 7 is driven to move towards the locking direction.
Referring to fig. 3 and 6, the cylinder lock assembly includes a lock cylinder 5, and the lock cylinder 5 is engaged with a clutch block 6. The knob 3 is a hollow cylindrical body, so the lock cylinder 5 is positioned in the cavity of the knob 3. Specifically, the end of the clutch block 6 facing the lock cylinder 5 is formed with a first clamping portion 91, and the end of the lock cylinder 5 facing the clutch block 6 is provided with a second clamping portion 92 that is in clamping engagement with the first clamping portion 91. Preferably, the first clamping portion 91 is a clamping block, and the second clamping portion 92 is a groove into which the clamping block is inserted. Referring to fig. 5, the size of the stirring portion 31 of the knob 3 is smaller than the size of the notch 62 of the clutch block 6, so that the clutch block 6 can still be driven to rotate by the lock cylinder 5 in the locked state of the knob 3, that is, the stirring portion 31 of the knob 3 is in clearance fit with the notch 62, the lock cylinder 5 can rotate relative to the knob 3 under the condition that the knob 3 is locked by the setting of the notch 62, and the stirring portion 31 acts as a limiting mechanism to limit the rotating angle of the clutch block 6, so that after the spring lock assembly is unlocked by a key, the lock cylinder 5 can drive the clutch block 6 to drive the lock block 7 to unlock.
In this embodiment, in order to further improve the smoothness of unlocking and locking, the lock cylinder 5, the clutch block 6 and the knob 3 are coaxially arranged.
In the working process of the combination padlock of the embodiment, in the locked state, the fixed end of the lock rope 2 is fixedly arranged in the mounting hole 13 of the lock shell 1, the free end of the lock rope 2 is inserted into the through hole 14 of the lock shell 1, and the free end is inserted into the lock hole 71 of the lock block 7 to be locked. When the coded wheel assembly 4 is unlocked, the coded wheel assembly is right, the wheel shaft 41 is in a telescopic state, the wheel shaft 41 releases the locking of the knob 3, the knob 3 is rotated by external force, the poking part 31 of the knob 3 abuts against the side wall of the notch 62 of the clutch block 6 to drive the clutch block 6 to rotate, the lug 61 of the clutch block 6 slides along the curved groove 72 in the rotating process of the clutch block 6, and the rotary freedom degree of the lock block 7 is limited by the lock shell 1, the lug 61 of the clutch block 6 abuts against the groove wall of the curved groove 72, so that the rotary motion of the clutch block 6 is converted into the horizontal motion of the lock block 7, and the clutch block 6 pushes the lock block 7 to move towards the unlocking direction, so that the locking hole 71 of the lock block 7 releases the clamping of the lock rope 2, and the unlocking of the coded wheel assembly 4 is realized. When the coded wheel assembly 4 is locked, the free end of the lock rope 2 is inserted into the through hole 14 of the lock shell 1, the knob 3 is reversely rotated, the protruding block 61 and the curve groove 72 can guide the lock block 7 to lock the lock rope 2 until the wheel shaft 41 is inserted into the clamping groove 34, the coded number is stirred, so that the locking is realized, the action of the reverse rotation knob 3 of a human hand can be subtracted from the arrangement of the reset spring 8, the automatic return of the lock block 7 is realized by the elastic force provided by the reset spring 8, and the operation is simpler and more convenient.
When the spring lock assembly is unlocked, a key is inserted to rotate the lock cylinder 5, and as the lock cylinder 5 is in clamping fit with the clutch block 6, the lock cylinder 5 drives the clutch block 6 to rotate, the stirring part 31 of the knob 3 also rotates in the notch 62 in the rotating process of the clutch block 6, and the clutch block 6 rotates to push the lock block 7 to move towards the unlocking direction under the matching of the convex block 61 and the curve groove 72, so that the locking hole 71 of the lock block 7 releases the clamping of the lock rope 2, and the unlocking of the lock cylinder 5 is realized. When the cylinder lock assembly is locked, the key is reversely rotated, so that the lock cylinder 5 is driven to reversely rotate, and the locking block 7 is guided to move towards the locking direction under the cooperation of the convex block 61 and the curve groove 72, so that locking is realized.
Compared with the prior art, through adopting rotary knob 3 to lock or unblock, knob 3 drives locking piece 7 through lock accuse mechanism and locks and releases locking rope 2, has replaced the mode of button horizontal migration in the past, has optimized the transmission relation between each part, makes whole transmission process compacter and smooth, has slowed down wearing and tearing, has improved the life of padlock.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
