[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, device, product or end that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or ends.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The utility model discloses a specific implementation of a password padlock, see Figure 1 and Figure 2 The combination padlock includes a lock case 1 with a lock hole 2 and a lock rope 3. The lock case 1 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 are detachably connected by screws or a clamping structure. One end of the lock rope 3 is fixedly clamped in the lock case 1, and the other end of the lock rope 3 is inserted into the lock hole 2, and one end of the lock rope 3 in the lock hole 2 can slide along the lock hole 2, so that the lock rope 3 is locked in the lock hole 2 to achieve locking, or the lock rope 3 is pulled out of the lock hole 2 to achieve unlocking.

[0029] Optionally, the lock hole 2 of the lock housing 1 is arranged in a gourd shape, that is, the lock hole 2 includes a first through hole 21 and a second through hole 22 connected to the first through hole 21, wherein the aperture of the first through hole 21 is smaller than the aperture of the second through hole 22. In order to achieve locking, a locking end is formed at the end of the lock rope 3 inserted into the lock hole 2. In this embodiment, the locking end is a spherical body 31, the outer diameter of the spherical body 31 is larger than the aperture of the first through hole 21, and the outer diameter of the spherical body 31 is smaller than the aperture of the second through hole 22. The outer diameter of the spherical body 31 is also larger than the outer diameter of the lock rope 3, but the outer diameter of the lock rope 3 is smaller than the connecting portion between the first through hole 21 and the second through hole 22, so that the lock rope 3 can slide back and forth between the first through hole 21 and the second through hole 22. When locking, since the outer diameter of the spherical body 31 is smaller than the aperture of the second through hole 22, the spherical body 31 of the lock rope 3 can be easily inserted into the lock housing 1 from the second through hole 22, and then the locking end of the sliding lock rope 3 with the spherical body 31 passes through the connecting portion, so that the spherical body 31 of the lock rope 3 slides into the first through hole 21. Since the outer diameter of the spherical body 31 is larger than the aperture of the first through hole 21, the lock rope 3 cannot escape from the first through hole 21 of the lock hole 2, thereby achieving locking. In some embodiments, the locking end of the lock rope 3 inserted into the lock hole 2 can also be other shapes, such as a teardrop shape, a triangle or a square or an irregular shape, as long as the locking end can be inserted into the lock hole 2 from the second through hole 22, but cannot be pulled out from the first through hole 21.

[0030] In this embodiment, an outwardly expanded chamfer is provided at the opening of the second through hole 22 to facilitate the locking end of the locking rope 3 to be inserted into the second through hole 22 .

[0031] In this embodiment, combined with Figure 2 and Figure 3 A lock block 4 for locking the lock rope 3 is provided in the lock housing 1. The lock block 4 is located at the lower side of the lock hole 2 and abuts against the spherical body 31 at the end of the lock rope 3 to limit the sliding of the locking end of the lock rope 3. Specifically, the lock block 4 can slide and rotate relative to the lock housing 1. Furthermore, the lock block 4 is arranged in the horizontal direction, and a long hole 41 is provided at the end of the lock block 4 away from the lock hole 2. A rotating shaft 40 is fixedly installed in the lock housing 1. In the assembled state, the long hole 41 of the lock block 4 is sleeved on the outer peripheral side of the rotating shaft 40, and the rotating shaft 40 can slide in the long hole 41 along its length, and the lock block 4 can also rotate around the rotating shaft 40.

[0032] The working process of the lock block 4 is as follows: in the locked state, the lock block 4 slides horizontally to the locked position and cannot move. At this time, the end of the lock block 4 abuts against the spherical body 31 at the end of the lock rope 3, so that the spherical body 31 of the lock rope 3 cannot slide, thereby achieving the locking of the lock rope 3. When unlocking, in the absence of other components hindering the lock block 4, the lock block 4 can slide in the horizontal direction away from the lock rope 3, so that the lock block 4 releases the abutment against the spherical body 31, so that the lock rope 3 can slide in the lock hole 2, thereby unlocking the lock rope 3; or, other components drive the lock block 4 to rotate around the rotating shaft 40, so that the lock block 4 no longer abuts against the spherical body 31 at the end of the lock rope 3, thereby releasing the lock block 4 from locking the lock rope 3, thereby achieving unlocking.

[0033] In order to improve the smoothness of unlocking the lock, a wedge-shaped portion 42 is formed at the end of the lock block 4 facing the lock hole 2, and the upper end surface of the wedge-shaped portion 42 facing the lock hole 2 is an inclined surface, and the inclined surface is an inclined surface inclined upward along the direction from the first through hole 21 to the second through hole 22, or the inclined surface is an inclined surface inclined downward along the locking sliding direction of the lock block 4. The inclined surface is more conducive to the lock rope 3 pushing the lock block 4 to slide or rotate, thereby improving the smoothness of unlocking.

[0034] Combination Figure 2 and Figure 3 The lock housing 1 is also provided with a lock core assembly 6 and a code wheel assembly 5. Both the lock core assembly 6 and the code wheel assembly 5 can lock the lock block 4 so that it cannot move to achieve locking of the lock rope 3. Both the lock core assembly 6 and the code wheel assembly 5 can lock the lock block 4 and also unlock the lock block 4 so that it can move to achieve unlocking of the lock rope 3. Specifically, the code wheel assembly 5 includes a retractable axle 51, which is arranged in the vertical direction and is located on the rotation path of the lock block 4. In the locked state, the axle 51 cannot move retractably, and the upper end of the axle 51 abuts against the bottom of the wedge-shaped portion 42 of the lock block 4 to limit the rotation of the lock block 4 relative to the lock housing 1. The lock block 4 cannot rotate, thereby locking the spherical body 31 at the end of the lock rope 3 in the first through hole 21, thereby achieving locking. When unlocking, the wheel axle 51 can move up and down, applying external force to the lock rope 3 to make it slide into the second through hole 22, and the spherical body 31 at the end of the lock rope 3 pushes the wedge-shaped part 42 of the lock block 4. The lock block 4 is pushed by the lock rope 3 and pushes the wheel axle 51 to retract downward, so that the lock block 4 rotates around the rotating shaft 40, thereby avoiding the lock rope 3, so that the spherical body 31 at the end of the lock rope 3 can slide from the first through hole 21 into the second through hole 22, thereby unlocking the lock.

[0035] Combination Figure 3 and Figure 4The lock core assembly 6 includes a lock core body 61 and a clutch block 62. The lock core body 61 is arranged in the horizontal direction, and the end of the lock core body 61 is fixedly connected to the clutch block 62. The clutch block 62 extends a clutch portion 63 toward the lock block 4 to abut against the lock block 4. The lock core body 61 drives the clutch portion 63 to rotate through the clutch block 62. In the locked state, the clutch portion 63 is located on the horizontal sliding path of the lock block 4. The clutch portion 63 abuts against the end of the lock block 4 away from the lock hole 2 in the horizontal direction to limit the lock block 4 from sliding relative to the lock housing 1. The lock block 4 cannot slide horizontally, so that the wedge-shaped portion 42 of the lock block 4 abuts against the spherical body 31 at the end of the lock rope 3 located in the first through hole 21, so that the spherical body 31 at the end of the lock rope 3 cannot slide from the first through hole 21 to the second through hole 22, thereby achieving the locking of the lock rope 3. When unlocking, rotate the lock core body 61, and the lock core body 61 rotates to drive the clutch block 62 to rotate. The rotation of the clutch block 62 drives the clutch part 63 and the lock block 4 to be staggered in the horizontal direction, so that the clutch part 63 releases the sliding limit on the lock block 4, so that the lock block 4 can slide in the horizontal direction. Specifically, the long hole 41 of the lock block 4 uses the rotating shaft 40 as a guide and support rod to slide horizontally to achieve unlocking.

[0036] Optionally, the clutch portion 63 of the clutch block 62 is provided with a downwardly inclined guiding slope 64, and the guiding slope 64 can push the locking block 4 back more smoothly when the clutch portion 63 returns, so that the locking process of the lock is smoother.

[0037] In this embodiment, see Figure 2 and Figure 3 As shown, the lock core assembly 6 and the code wheel assembly 5 are arranged in an L shape in the lock shell 1, wherein the lock core assembly 6 is arranged horizontally and close to the upper end of the lock shell 1, and the code wheel assembly 5 is arranged vertically and close to the side of the lock shell 1, so that a rectangular installation space can be formed in the lock shell 1, and the installation space is located between the lock core assembly 6 and the code wheel assembly 5, and the lock shell 1 is also fixedly installed with an electronic component 7, which is arranged in the installation space between the lock core assembly 6 and the code wheel assembly 5, so that the internal structure of the code padlock is more compact, and the volume is smaller when there are more functions. The electronic component 7 can improve the applicability of the lock, so that it has a positioning function, an identification function or other functions, thereby improving the functionality of the lock. The electronic component 7 is arranged in the installation space between the lock core assembly 6 and the code wheel assembly 5. Such a design can prevent other components from shielding or blocking the signal of the electronic component 7, and ensure the normal operation of the electronic component 7.

[0038] The password padlock of this embodiment uses the unlocking method of turning the lock rope 3 to replace the previous unlocking method of setting a button, which solves the problem of complex structure in the past. The unlocking method is more convenient and quick, and the operation is simpler. The overall structure of the lock is simpler and more compact, and the reasonable layout allows a larger installation space inside the lock, reducing the production cost of the lock and improving economic benefits.
