Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a bag and a zipper lock of the bag. Background Art

[0002] Existing luggage includes a first box body and a second box body, which are connected by a zipper. In order to facilitate the carrying and use of the luggage, a handle is installed on the first box body or the second box body. In order to prevent theft, the luggage is generally provided with a zipper lock that can be unlocked by both a key and a password. At present, this type of zipper chain is arranged in a long strip shape, that is, the password wheel assembly, the lock core assembly and the lock hook (lock hole) for locking the zipper piece are arranged in a horizontal and transverse manner.

[0003] See patent application number CN2020305063408, which discloses a suitcase with a handle and a straight zipper lock installed on the side of the suitcase. The handle and zipper lock are both installed on the first box body. This structure of arranging the two on the same box body is mainly for the convenience of box body manufacturing and processing. However, since the zipper lock is in a straight strip shape, it cannot be installed on the upper surface of the suitcase. Because the upper surface of the suitcase is often small, especially for some small suitcases, the length of the upper surface of the suitcase is not enough to accommodate the horizontal arrangement of the handle and zipper lock. If the zipper lock and handle are forced to be arranged horizontally, the handle cannot be in the center position, which will be very troublesome for carrying the suitcase. To overcome the problem of limited installation length, the suitcase has the zipper lock and handle installed on the side of the suitcase. In this way, the suitcase needs to be turned sideways or laid flat every time it is opened, which is very troublesome and unstable to use. In addition, the zipper lock is located on the side of the suitcase, which can easily scratch people's clothing or decorations, posing a safety hazard.

[0004] Refer to the patent document with application number CN2021200315168, which discloses a suitcase with a single lock and double opening. In order to overcome the unsafe problem of zipper lock and handle installed on the side of the suitcase, the zipper lock and handle are installed on the upper surface of the suitcase. However, due to the limited installation length of the upper surface of the suitcase, the handle and zipper lock cannot be installed on the first box body. The suitcase arranges the handle and zipper lock on the first box body and the second box body respectively, and the handle and zipper lock are arranged relative to each other. However, this arrangement has the problem that both the first box body and the second box body require additional processing, the production process is cumbersome, and the handle cannot be installed in the center position, which leads to high production costs. Summary of the Invention

DETAILED DESCRIPTION

[0032] The present invention is further described with reference to the following examples.

[0033] Example 1

[0034] An embodiment of a bag of the present invention is as follows Figure 1 As shown, the bag includes a first box body 11, a second box body 12, a handle and a zipper lock. The first box body 11 and the second box body 12 are connected by a zipper, and the zipper includes a zipper piece. As an improvement, the handle is fixedly installed in the middle of the upper surface of the first box body 11, and the zipper lock is fixedly installed on the first box body 11 in the transverse direction and is located to the side of the handle. The zipper lock includes a lock hole 20, a code wheel assembly 3 and a lock core assembly 4. The code wheel assembly 3, the lock core assembly 4, and the lock hole 20 are arranged along the longitudinal direction of the bag ( Figure 1 From top to bottom (vertically), they are arranged in sequence.

[0035] Since the lock hole 20, lock core assembly 4, and combination wheel assembly 3 of the zipper lock are arranged along the longitudinal direction of the luggage, the overall volume of the zipper lock is small, and the length occupied by the zipper lock in the horizontal direction is short. Therefore, the zipper lock and the handle are not restricted by the length of the upper surface of the luggage, and the handle can be in a central position, making the processing of the luggage more convenient and simple, and solving the problem that the installation of the zipper lock is restricted by the length of the upper surface of the luggage in the past.

[0036] In this embodiment, the depth of the first box body 11 is greater than the depth of the second box body 12, and the handle is located in the center of the upper surface of the bag. In this way, the first box body 11 will have sufficient length in the longitudinal direction for installing the zipper lock. Moreover, for some small bags, the first box body 11 is a box body with a relatively deep depth, and the second box body 12 is generally a very thin cover body. For small bags, the zipper lock of this embodiment is also suitable for installation on the upper surface of the bag.

[0037] In other embodiments, the zipper lock may also be provided with only a lock core assembly 4 opened with a key or only a password wheel assembly 3 unlocked with a password, and the specific selection and setting can be made according to actual conditions.

[0038] One embodiment of the zipper lock of the present invention is shown in Figure 2 and Figure 3 The zipper lock includes a lock housing, a combination wheel assembly 3, and a lock core assembly 4. A lock hole 20 with an upward opening is defined on the upper surface of the lock housing. The lock core assembly 4, combination wheel assembly 3, and lock hole 20 are spaced apart longitudinally along the lock housing. Specifically, the lock housing includes a first shell 21 and a second shell 22. The first shell 21 and the second shell 22 are fixed to a chassis and are independent of each other. The first shell 21 includes a first bottom shell 212 and a first front shell 211, while the second shell 22 includes a second bottom shell 222 and a second front shell 221. The lock hole 20 is defined on the first front shell 211 of the first lock housing, while the combination wheel assembly 3 and lock core assembly 4 are mounted within the second shell 22. In other embodiments, the first shell 21 and the second shell 22 may also be integrally formed.

[0039] In this embodiment, a lock hook 7 is rotatably mounted in the second housing 22, and a locking mechanism is provided between the second lock body and the first lock body to abut against the lock hook 7 to limit the rotation of the lock hook 7. Specifically, the locking mechanism includes a movable member 5 that can slide along the length of the lock housing.

[0040] The lock core assembly 4 can slide along the height direction (vertical direction) of the lock shell. It can be understood that the lock core assembly 4 is essentially a switch that can be pressed. The lock core assembly 4 is linked with the movable part 5. Figure 4Specifically, the movable part 5 extends a pair of mounting ears 51 toward the lock core assembly 4, and the lock core assembly 4 is installed between the two mounting ears 51. The lock core assembly 4 includes a housing 42 and a lock core body 41 rotatably installed in the housing 42. Guide posts 43 extend outward from both the left and right sides of the housing 42. Each mounting ear 51 is provided with a guide groove 52 inclined obliquely downward. The guide post 43 is inserted into the guide groove 52 and can slide along the guide groove 52. When unlocking, the lock core assembly 4 is pressed from the outside, so that the guide post 43 will abut the guide groove 52, converting the upward and downward sliding of the lock core assembly 4 into the sliding of the movable part 5 to the right. A spring can be provided to drive the movable part 5 to slide to the left. After the lock core assembly 4 returns to its original position, the movable part 5 automatically returns to its original position under the elastic force of the spring.

[0041] To prevent theft, the lock cylinder body 41 is designed to restrict the sliding of the movable member 5 when in the locked position. This means that the lock cylinder assembly 4 cannot be pressed when in the locked position. A downwardly extending stopper 44 extends from the lock cylinder body 41. A clutch member 6, which can slide along the length of the lock housing, is located between the combination wheel assembly 3 and the lock cylinder assembly 4. A protrusion 61 extends upward from the front end of the clutch member 6. When locked, the stopper 44 aligns with and abuts against the protrusion 61 in the height direction, limiting the vertical sliding of the entire lock cylinder assembly 4. The provision of the clutch member 6 achieves the desired locking effect.

[0042] When using a key to unlock, insert the key into the lock core body 41. By rotating the lock core body 41, the rotation of the lock core body 41 will drive the limiting part 44 to rotate around the lock core assembly 4. After rotating the lock core body 41, the limiting part 44 and the protrusion 61 of the clutch part 6 are staggered in the height direction. At this time, the lock core assembly 4 can be pressed. Pressing the lock core assembly 4 can make the lock core assembly 4 drive the movable part 5 to move, and the movement of the movable part 5 releases the movement restriction of the lock hook 7.

[0043] Combine Figure 4 The combination wheel assembly 3 includes a locking plate 31 pivotally mounted within the lock housing. It should be noted that the combination wheel assembly 3 is conventional. When the combination wheel assembly 3 enters an incorrect password, the locking plate 31 swings to a locked position. When the combination wheel assembly 3 enters a correct password, the locking plate 31 swings to an unlocked position. A pusher portion 32 extends downward from the end of the locking plate 31 facing the lock cylinder. A wedge-shaped block 62 extends upward from the rear end of the clutch member 6. This wedge-shaped block 62 has a guide slope, against which the pusher portion 32 abuts.

[0044] The working process of the code wheel assembly 3 is as follows: when locking, the lock plate 31 swings (swings counterclockwise) to the locked position, and the pusher 32 pulls the clutch 6 to the locked position, so that the protrusion 61 of the clutch 6 is aligned with and abuts the limiter 44 of the lock cylinder body 41 in the height direction, thereby limiting the freedom of the lock cylinder assembly 4 in the height direction and achieving locking. When unlocking, the lock plate 31 swings (swings clockwise) to the unlocked position, and the pusher 32 moves upward to disengage the clutch 6. By providing an elastic member between the clutch 6 and the lock housing, the elastic member drives the clutch 6 to move in the unlocking direction, so that the protrusion 61 of the clutch 6 is staggered in the height direction with the limiter 44 of the lock cylinder body 41. At this time, the lock cylinder assembly 4 can be pressed. Pressing the lock cylinder assembly 4 can cause the lock cylinder assembly 4 to drive the movable member 5 to move, and the movable member 5 movement releases the movement restriction of the lock hook 7.

[0045] In this embodiment, combined with Figure 5 and Figure 6 The lock hook 7 includes a hook portion 71 for locking the zipper tab and a rod portion 72 integrally formed with the hook portion 71. The locking mechanism also includes a barb 53 formed at the end of the movable member 5 facing the lock hook 7. An elastic arm 213 that can be elastically deformed extends from the bottom of the first bottom shell 212 toward the lock hook 7. One end of the elastic arm 213 is integrally formed with the first bottom shell 212 as a fixed end, and the other end of the elastic arm 213 extends into the first bottom shell 212 as a free end. The elastic arm 213 extends toward the lock hook 7 to form a latching protrusion 214 that abuts against the lock hook 7. The latching protrusion 214 mainly cooperates with the groove 74 of the rod portion 72 of the lock hook 7.

[0046] When locking, the latching protrusion 214 of the elastic arm 213 abuts against the groove 74 of the rod 72 of the lock hook 7, thereby restricting the rotation of the lock hook 7. When unlocking, the lock core assembly 4 is pressed externally, and the lock core assembly 4 slides downward, driving the movable member 5 to slide in the unlocking direction (left side). The barb 53 of the movable member 5 abuts against the elastic arm 213, causing the free end of the elastic arm 213 to move downward, so that the latching protrusion 214 of the elastic arm 213 disengages from the groove 74 of the rod 72 of the lock hook 7, thereby releasing the movement restriction on the lock hook 7. When locking, the movable member 5 returns to its original position, and the barb 53 releases the abutment on the elastic arm 213, causing the elastic arm 213 to return to its original position due to its own elastic force, thus achieving locking.

[0047] The zipper lock of this embodiment is small in size, occupies little space in the horizontal direction, has a simple and compact structure, and allows for smooth unlocking and locking operations.

[0048] Example 2

[0049] The second specific embodiment of the zipper lock of this application is shown in Figures 7 to 9As shown, the main technical solution of this embodiment is the same as that of Example 1. Features not explained in this embodiment are explained in Example 1 and will not be repeated here. The difference between this embodiment and Example 1 is that the structure of the locking mechanism is different. In this embodiment, the locking mechanism includes an unlocking block 54 and a locking block 8. The unlocking block 54 is formed at the end of the movable member 5 facing the lock hook 7. The locking block 8 can slide along the length of the lock housing. The side of the locking block 8 is provided with an unlocking groove 81. The bottom surface of the locking block 8 extends downward to form an unlocking portion 82. The unlocking block 54 and the unlocking portion 82 are on the same horizontal plane.

[0050] When locking, the movable member 5 is in the locked position, the rod 72 of the lock hook 7 abuts against the outer side surface of the lock block 8 itself, and the rod 72 of the lock hook 7 and the unlocking groove 81 of the lock block 8 are staggered in the longitudinal direction, so that the rod 72 of the lock hook 7 abuts against the side surface of the lock block 8, thereby restricting the rotation of the lock hook 7. When unlocking, the lock core assembly 4 is pressed from the outside, and the lock core assembly 4 drives the movable member 5 to slide in the unlocking direction. The unlocking block 54 of the movable member 5 abuts and pushes the unlocking portion 82 of the lock block 8, so that the lock block 8 slides in the unlocking direction until the unlocking groove 81 of the lock block 8 is aligned with the rod 72 of the lock hook 7 in the transverse direction. The lock hook 7 can rotate with the help of the torsion spring, so that the rod 72 of the lock hook 7 rotates into the unlocking groove 81 of the lock block 8, thereby releasing the rotation restriction of the lock hook 7 and achieving unlocking.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
