The coded lock of this embodiment is suitable for use in a case having a multi-layer structure, and therefore, the coded lock of this embodiment has two lock holes 13, the two lock holes 13 are disposed at the face shell 111 of the first lock shell 11, and each lock hole 13 is provided with a lock hook 5 rotatably mounted in the first lock shell 11, and an elastic member for driving the lock hook 5 to flip upwards is disposed between the lock hook 5 and the first lock shell 11. In order to realize the anti-theft function, an upper locking block 6 for propping against the locking hook 5 to realize locking is arranged in the lock shell, the number of the upper locking blocks 6 is equal to that of the locking hooks 5, and each locking block is matched with one locking hook 5.

In order to facilitate assembly and protect the upper locking piece 6, in conjunction with fig. 4 and 5, a locking hook seat 50 for covering the upper locking piece 6 is further provided in the first locking shell 11, the locking hook seat 50 is pressed and fixed with the face shell 111 of the first locking shell 11, two upper locking pieces 6 are all installed in the same locking hook seat 50, each upper locking piece 6 can slide in the locking hook seat 50 along the length direction perpendicular to the first locking shell 11, the top end faces of the locking hook seat 50 extend upwards to form a pair of mounting lugs 501, two side faces of the locking hook 5 extend outwards to form columnar hinge parts 55, and when assembled, the hinge parts 55 are placed at the top ends of the mounting lugs 501, so that the locking hook seat 50 holds the locking hook 5, and the locking hook 5 can rotate relative to the first locking shell 11.

Referring to fig. 4 and 5, the latch hook 5 includes a hook portion 53 and a holding portion 54, and the hook portion 53 is used for hooking the zipper strip. The upper locking piece 6 comprises a locking piece body in a straight strip shape, and the locking piece body is provided with an unlocking groove 61. In the locked state, the lock block body of the upper lock block 6 abuts against the clamping portion 54 of the lock hook 5, and at this time, the clamping portion 54 is staggered from the unlocking groove 61, so that the lock hook 5 is limited to be rotationally unlocked. When unlocking, the upper locking piece 6 moves along the width direction of the locking hook seat 50, after the unlocking groove 61 is aligned with the clamping part 54, the clamping part 54 can be placed in the unlocking groove 61, so that the locking hook 5 is released from rotation limitation and can be rotated for unlocking. The elastic member can drive the latch hook 5 to return automatically, and similarly, in order to enable the upper latch block 6 to return automatically, an elastic member is also arranged between the upper latch block 6 and the latch hook seat 50.

In order to realize the unlocking movement of the upper locking piece 6, an upper movable piece 71 for driving the upper locking piece 6 to move is also arranged in the lock shell, as shown in fig. 6. The bottom surface of the upper locking piece 6 extends downwards to form an unlocking part 62, one end of the upper movable piece 71, which is close to the upper locking piece 6, is provided with an unlocking hole 73 for inserting the unlocking part 62, a second wedge surface 74 is arranged in the unlocking hole 73, and the unlocking part 62 is provided with a first wedge surface 63 which is complementary with the second wedge surface 74. Preferably, the unlocking portion 62 of the upper lock block 6 has a trapezoidal cross-sectional shape. When the upper movable block 71 moves towards the right in operation, the second wedge surface 74 of the unlocking hole 73 of the upper movable block 71 abuts against the first wedge surface 63 of the unlocking part 62 of the upper locking block 6, so that the transverse movement of the upper movable block 71 is converted into the longitudinal movement of the upper locking block 6, and the upper locking block 6 releases the rotation restriction on the locking hook 5, and thus locking is realized.

The lock hook 5 is required to be unlocked by the coded lock of the embodiment, and then the upper movable block 71 must be moved, and the upper movable block 71 moves to drive the upper lock block 6 to be dislocated with the lock hook 5, so that the lock hook 5 can be unlocked. Thus, the combination lock is provided with a push assembly for pushing the upper movable block 71 in the longitudinal direction of the lock housing.

Referring to fig. 7, the pushing assembly includes a pushing body 21 and a lock core 22, wherein the lock core 22 is rotatably installed in the pushing body 21, it should be noted that the lock core 22 is a conventional cylinder lock, i.e. after a key is inserted, the lock core 22 can rotate relative to the pushing body 21, and the lock core 22 cannot rotate without the key inserted. The pushing assembly can slide along the length direction of the first lock shell 11, the pushing assembly is clamped with the upper movable block 71, specifically, the bottom of the lock cylinder 22 downwards extends to form two first poking parts 23 and second poking parts 24 which are arranged at intervals, the end part of the upper movable block 71, which is close to the second poking part 24, is provided with a clamping hole for the second poking part 24 to insert, the clamping hole is a strip hole, and the second poking part 24 can slide along the length direction of the clamping hole after being inserted into the clamping hole, so that the movable connection between the pushing assembly and the upper movable block 71 is realized. Therefore, when no other mechanism blocks the movement of the pushing body 21, the pushing body 21 is pushed to the left, the pushing body 21 drives the lock cylinder 22 to slide to the left along the length direction of the first lock shell 11, and the second poking part 24 of the lock cylinder 22 clamps the upper movable block 71, so that the pushing body 21 is pushed to slide to drive the upper movable block 71 to move, and unlocking of the lock hook 5 is realized.

In addition, since the lock cylinder 22 is locked to the upper movable block 71, the upper movable block 71 is also limited to slide in the first lock housing 11 only in the longitudinal direction of the first lock housing 11, and when the key is used for unlocking, the key is inserted and the lock cylinder 22 is rotated, the rotation of the lock cylinder 22 is converted into the horizontal sliding of the upper movable block 71, so that the lock hook 5 is unlocked by the upper movable block 71. When locking, the lock core 22 only needs to be rotated in the opposite unlocking direction, and the lock core 22 rotates and drives the upper movable block 71 to return, so that locking can be completed.

In this embodiment, please see fig. 1 to 2, two spaced fastening holes 15 are provided on the side surface of the second lock case 12, and each fastening hole 15 is provided with a lock tongue 8 capable of rotating relative to the second lock case 12, it should be noted that the rotatable mounting mode of the lock tongue 8 is only required to adopt a structure that the lock hook 5 is rotatably mounted in the first lock case 11, and similarly, in order to facilitate the automatic return of the lock tongue 8, a torsion spring for driving the lock tongue 8 to turn over towards the locked state is provided between the lock tongue 8 and the second lock case 12.

Referring to fig. 10, one end of the lock tongue 8 facing the fastening hole 15 forms a fastening hook 81 for fastening the external fastener, and the other end of the lock tongue 8 is suspended, i.e., a certain distance exists between the end of the lock tongue 8 and the inner bottom surface of the second lock case 12, which approximates to a lever structure. Referring to fig. 8 to 9, a lower lock block 9 is further disposed in the second lock case 12, and the lower lock block 9 is slidable along the length direction of the second lock case 12, and preferably, the lower lock block 9 is disposed in a T shape. The end of the lower locking piece 9 facing the tongue 8 is formed with a guide slope 92 inclined obliquely upward. In the locked state, the upper end of the guide inclined plane 92 abuts against the suspended end of the lock tongue 8, and in the unlocking process, the guide inclined plane 92 of the lower lock block 9 interferes with the suspended end of the lock tongue 8 to drive the lock tongue 8 to gradually turn over towards the unlocked state, and in the unlocked state, the lower end of the guide inclined plane 92 abuts against the suspended end of the lock tongue 8.

It should be noted that, the pushing assembly, the latch hook 5, the upper lock block 6, the latch hook seat 50, and the upper movable block 71 are all installed in the first lock case 11, and the latch tongue 8 and the lower lock block 9 are all installed in the second lock case 12, in order to enable the pushing assembly to drive the lower lock block 9 to move, the first lock case 11 is further provided therein with the lower movable block 72, the lower movable block 72 may slide along the length direction of the first lock case 11, one end of the lower movable block 72, which is far from the pushing body 21, faces to the extending retaining arm 721, the retaining arm 721 of the lower movable block 72 penetrates out of the bottom of the first lock case 11, and the middle part of the lower lock block 9 extends upward to form a retaining hole 91, and the retaining arm 721 extends toward the top of the second lock case 12 and is inserted into the retaining hole 91, so that the lower movable block 72 and the lower lock block 9 are connected as a whole, and when the lower movable block 72 slides horizontally, the lower lock block 9 slides horizontally.

Referring to fig. 7 and 10, the bottom of the lock core 22 extends downwards to form a first poking part 23 spaced from the second poking part 24, and the end of the lower movable block 72, which is close to the first poking part 23, is provided with a clamping groove for the first poking part 23 to be inserted, and the first poking part 23 can slide along the length direction of the clamping groove after being inserted into the clamping groove, so that movable connection between the pushing assembly and the lower movable block 72 is realized. Therefore, under the condition that no other mechanism blocks the movement of the pushing body 21, the pushing body 21 is pushed to the right, the pushing body 21 can drive the lock cylinder 22 to slide to the right along the length direction of the first lock shell 11, and as the first poking part 23 of the lock cylinder 22 clamps the lower movable block 72, the pushing body 21 is pushed to slide so as to drive the lower movable block 72 to move, so that unlocking of the lock tongue 8 is realized.

In addition, since the lock cylinder 22 is clamped by the lower movable block 72, and the lower movable block 72 is also limited in the second lock housing 12 to be capable of sliding only along the length direction of the second lock housing 12, when the key is used for unlocking, the key is inserted and the lock cylinder 22 is rotated, the rotation of the lock cylinder 22 is converted into the horizontal sliding of the lower movable block 72, so that the lock tongue 8 is unlocked by the lower movable block 72. When locking, only the lock core 22 is required to be rotated in the opposite unlocking direction, and the lock core 22 rotates and drives the lower movable block 72 to return, so that locking can be completed.

As an improvement, please refer to fig. 3, the combination lock further comprises a combination wheel assembly 3. The cipher wheel assembly 3 comprises a wheel shaft 31 which is arranged along the length direction of the lock shell and can reciprocate to stretch and retract, and a wheel shaft spring 32 which is sleeved on the outer peripheral side of the wheel shaft 31, and it should be noted that the cipher wheel assembly 3 is of a conventional cipher wheel structure, the wheel shaft spring 32 is an elastic reset piece of the cipher wheel assembly 3, the cipher is correct, the wheel shaft 31 can reciprocate to stretch and retract, the cipher is wrong, and the wheel shaft 31 cannot stretch and retract. The wheel axle 31 is arranged at the side of the pushing body 21 and is positioned on the motion track of the pushing body 21, the working process is that the wheel axle 31 is in an extending state due to wrong passwords, the end part of the wheel axle 31 abuts against and limits pushing sliding to realize locking, the password is correct, the wheel axle 31 is in a retractable state, the pushing component slides towards the unlocking direction and pushes the wheel axle 31 to retract, the wheel axle spring 32 is in a compressed state, the pushing component slides and drives the lower movable block 72 or the upper movable block 71 to move, the upper movable block 71 or the lower movable block 72 moves to drive the corresponding locking block or the lock tongue 8 to move, and when the wheel is locked, the wheel axle spring 32 in the compressed state drives the wheel axle 31 to extend to return, and the wheel axle 31 extends to return to push the pushing body 21 to return.

In order to make the operation of the coded lock more humanized, the motion of the pushing body 21 needs to be designed to be that the lock tongue 8 in the second lock shell 12 is independently unlocked towards the right and the lock hook 5 in the first lock shell 11 is independently unlocked towards the left, the traditional design thought is that one coded wheel assembly 3 is arranged on the left side and the right side of the pushing body 21 and used for limiting the pushing body 21 to move towards the left and the right in the locked state respectively, but the adoption of two coded wheel assemblies 3 can certainly lead to the increase of manufacturing cost and the increase of the whole volume of the coded lock, and in order to solve the problem that the pushing body 21 cannot move towards the left and the right in the locked state by adopting a single coded wheel assembly 3, the clutch 4 is additionally arranged. Specifically, referring to fig. 8 and 9, the pushing assembly is further provided with a clutch member 4, the clutch member 4 is mounted on a side of the pushing body 21 facing the wheel axle 31, and the clutch member 4 can rotate relative to the pushing body 21. As a preferable scheme, the middle part of the clutch member 4 is provided with a hinge hole, the pushing body 21 is provided with a guide groove 200 positioned below the hinge hole, the first lock shell 11 (the top end surface of the bottom plate 113) is fixedly connected with a rotating shaft 40, the top end of the rotating shaft 40 passes through the guide groove 200 of the pushing body 21 and then is inserted into the hinge hole of the clutch member 4, the clutch member 4 can rotate relative to the rotating shaft 40, and the rotating shaft 40 can slide along the length direction of the guide groove 200 relative to the guide groove 200.

Preferably, the pushing body 21 is further provided with a front limit groove 201 and a rear limit groove 202 respectively located at the front side and the rear side of the guide groove 200, the bottom surface of the clutch member 4 downwardly extends to form a front push rod 41 inserted into the front limit groove 201 and a rear push rod 42 inserted into the rear limit groove 202, and the front push rod 41 and the rear push rod 42 are staggered and diagonally arranged in the length direction of the lock case.

During locking, the front push rod 41 abuts against the right inner side wall of the front limit groove 201, and because the wheel axle 31 is in a locking state, the wheel axle 31 cannot perform telescopic movement, so that the pushing body 21 cannot move towards the left under the obstruction of the front limit groove 201 and the front push rod 41, and the rear push rod 42 abuts against the left inner side wall of the rear limit groove 202, so that the pushing body 21 cannot move towards the right under the obstruction of the rear limit groove 202 and the rear push rod 42, locking is achieved, and the pushing body 21 can be limited to move towards the left and the right by adopting the single coded wheel assembly 3 through the clutch 4. When unlocking, the wheel axle 31 can move in a telescopic way, the pushing body 21 slides towards the left side, the pushing body 21 pushes the front push rod 41 to enable the clutch piece 4 to rotate clockwise, the rear push rod 42 slides along the rear limit groove 202, when unlocking, the pushing body 21 slides towards the right side, the pushing body 21 pushes the rear push rod 42 to enable the clutch piece 4 to rotate clockwise, and the front push rod 41 slides along the front limit groove 201. It should be noted that, no matter the pushing body 21 slides to the left or the right, as long as the axle 31 is in the unlocked state, the clutch member 4 rotates and abuts against the end of the pressing axle 31, so as to assist the pushing body 21 to unlock, so that the force required for unlocking is smaller, and the unlocking process is smoother and more stable.

It should be noted that, the clutch member 4 and the pushing body 21 are limited by the limiting groove and the push rod, so that in the locked state, the pushing body 21 can be always located at the middle position of the operation cavity of the face shell 11 (the operation cavity is a through hole formed in the face shell 11 and is mainly used for installing the pushing body 21 and allowing the pushing body 21 to slide leftwards or rightwards), instead of the conventional manner of limiting pushing the pushing body 21 by using other elastic members such as springs, in the conventional scheme, due to the elastic force of the springs, the pushing body 21 cannot be centered, and after the pushing body 21 returns, the pushing body 21 is always subject to the elastic force exerted by the springs (elastic members), so that the pushing body 21 always deviates leftwards or rightwards in the operation cavity of the face shell 11.

In another embodiment, if the coded lock does not need to be provided with the lock hook 5, that is, the coded lock removes the function of locking the external zipper strip, the lock hook 5, the upper lock block 6 and the upper movable block 71 do not need to be provided, only the lock shell, the pushing component, the coded wheel component 3, the lower movable block 72, the lower lock block 9, the clutch piece 4 and the lock tongue 8 are reserved, so that the coded lock only used for locking the external front cover lock catch can be formed, and when only the lock hook 5 or the lock tongue 8 needs to be provided, the pushing body 21 only needs to move in one direction (right or left) to unlock, and the clutch piece 4 does not need to be provided.

According to the password lock for the multi-layer luggage, the wheel axle spring 32 of the password wheel assembly 3 can serve as the reset piece to automatically reset the sliding pushing, and the wheel axle spring 32 is sleeved on the wheel axle body 31, so that the wheel axle spring 32 only stretches along the axial direction of the wheel axle body, the middle part of the traditional reset spring is not provided with other auxiliary parts to support the wheel axle spring, the traditional reset spring is easy to twist, the middle part of the wheel axle spring 31 cannot twist or bend, and therefore, compared with the traditional reset spring, the traditional password lock has the advantages that the pushing body 21 cannot be driven to return reliably, the service life is longer, the pushing cannot be normally driven to return, and the reset spring is not required to be additionally arranged in the password lock, so that the internal structure of the password lock is simplified, the assembly process of the password lock is simplified, and the problem of complex structure in the past is solved. The coded lock has the advantages of compact integral structure, reasonable layout, smooth unlocking and locking processes, and quick and convenient operation, enhances the experience of consumers, and improves the convenience of the coded lock.

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.
