Description

Technical Field

[0001] This utility model relates to the field of luggage lock technology, specifically to a luggage lock that is easy to assemble and disassemble. Background Technology

[0002] Commercially available bag locks typically consist of a lock body and a base. The installation process involves first inserting the lock body from the outside of the bag into its designated mounting position, with the lower part of the lock body inserted into the bag and the upper part secured to the bag. Then, the base is inserted into the inside of the bag, fitting over the lower part of the lock body from the inside. Finally, screws are used to secure the lock body and base together from the outside or inside of the bag. This type of bag lock is cumbersome to install, requiring a screwdriver each time, resulting in high labor intensity. It also necessitates pre-drilling screw holes in the bag, making installation extremely inconvenient.

[0003] Subsequently, a convenient bag lock was disclosed in Chinese patent document CN216076673U, which includes a lock body and a base fitted at the bottom of the lock body. A locking slide is provided between the outer side of the lock body and the inner side of the base. A one-way sliding locking mechanism is provided between the base and the locking slide for one-way locking the sliding slide along the length of the base. The base has a limiting mechanism for restricting the vertical movement of the locking slide. A vertical locking mechanism is provided between the locking slide and the lock body for restricting the vertical movement of the lock body. A sliding window is opened at the bottom of the base, through which part of the locking slide is exposed. This lock is easy to install, has a simple and compact structure, and is securely installed. By limiting the degree of freedom of the lock body through the limiting mechanism, the one-way sliding locking mechanism, and the vertical locking mechanism, the bag lock can be installed without the need for other auxiliary tools, making operation simple and quick.

[0004] Further investigation revealed that the components of the aforementioned prior art are complex, especially requiring additional locking sliding parts to secure the lock body. Therefore, the inventors developed a technology, such as application number 2024212974615, entitled "A Snap-on Installation Bag Lock," which has not yet been disclosed. The bag lock includes a base and a lock body, both elongated. The base has a receiving groove for the lock body to be inserted into, the length of which is greater than the length of the lock body, allowing the lock body to move along its length within the groove. A first snap-on structure and a second snap-on structure are provided between the lock body and the base. After the lock body moves to a preset position in the receiving groove, the first snap-on structure restricts its movement within the groove, and the second snap-on structure restricts its movement away from the groove. During installation, the lock body is first placed into the receiving groove, and then moved along its length to the preset position. The first snap-on structure then restricts the lock body's movement within the groove, and the second snap-on structure prevents it from disengaging from the groove, thus achieving a mutual snap-on fixation between the lock body and the base. Compared with existing technologies, the lock body and base structure alone can achieve interlocking fixation without the need for additional screws and locking components, making installation convenient and cost-effective.

[0005] However, the inventors discovered other ways to achieve this during further research and development. Summary of the Invention

[0006] In view of the above-mentioned technical problems existing in the prior art, this utility model provides a bag lock that is easy to assemble and disassemble.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A bag lock that is easy to assemble and disassemble is provided, comprising a base and a lock body, both of which are elongated strips. The base includes a bottom wall, a long side wall, and an end side wall that together form an upward-facing receiving groove. The lock body is embedded in the receiving groove and its top is exposed. Its characteristic is:

[0009] The length of the receiving groove is greater than the length of the lock body, so that the lock body can move along the length direction in the receiving groove;

[0010] The base has a first locking part on its long side wall and a second locking part on the lock body; the base has a first fitting structure and the lock body has a second fitting structure; when the lock body slides forward to a preset position, the first fitting structure and the second fitting structure fit together along the length of the base to restrict the lock body from longitudinally disengaging from the receiving groove; and the first locking part and the second locking part engage to restrict the lock body from moving in the opposite direction.

[0011] The base with the first retaining part can be bent outward by an external force, thereby releasing the engagement between the first retaining part and the second retaining part.

[0012] As a further optional solution, the long side wall of the base is provided with a first weakening hole and a second weakening hole arranged vertically, and an arm beam is formed between the first weakening hole and the second weakening hole, and a first holding part is provided on the arm beam.

[0013] As a further optional solution, both the first weakening hole and the second weakening hole are elongated holes arranged along the length of the base.

[0014] As a further alternative, the second weakening hole extends to the bottom wall, and the arm beam extends with a hand-bend.

[0015] As a further alternative, the lever extends toward the second weakening hole and aligns with the bottom wall of the base.

[0016] As a further alternative, the first and second locking parts are helical teeth with opposite tilting directions.

[0017] As a further alternative, the first fitting structure is a groove formed on the side wall of the base, and the second fitting structure is a block formed on the side wall of the lock body. When the lock body moves along the length direction of the receiving groove, the block is inserted into the groove.

[0018] As a further alternative, the insert and slot are provided with mating bevels so that the insert gradually tightens during insertion into the slot.

[0019] As a further alternative, there are multiple inserts and slots that correspond one-to-one with each other, with multiple inserts distributed on the long sidewall of the lock body and multiple slots distributed on the long sidewall of the base.

[0020] As a further optional solution, the inner wall of the base is provided with reinforcing ribs, some of which form the groove.

[0021] The beneficial effects of this utility model are:

[0022] This utility model discloses a bag lock that is easy to assemble and disassemble. During installation, the lock body is first placed into the receiving groove. Then, the lock body is moved along the length of the base to a preset position. The first and second engaging structures then engage along the length of the base to prevent the lock body from longitudinally disengaging from the receiving groove. Furthermore, the first and second locking parts engage to prevent the lock body from moving in the opposite direction. This achieves mutual locking and fixation between the lock body and the base. Compared with existing technologies, this design achieves mutual locking and fixation solely through the structure of the lock body and base, eliminating the need for additional screws and locking components. It is easy to install and has low cost.

[0023] When the lock body needs to be removed, manually bend the base with the first locking part outward to deform it, thereby releasing the locking relationship between the first locking part and the second locking part. Then the lock body can be moved to separate the first and second locking structures, and the lock body can be removed quickly and easily. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] This embodiment provides a bag lock that is easy to assemble and disassemble, such as... Figures 1 to 3 As shown, the device includes a base 1 and a lock body 2, both of which are elongated. The base 1 includes a bottom wall 11, a long side wall 12, and an end side wall 13 that together form an upward-facing receiving groove 14. The lock body 2 is embedded in the receiving groove 14 with its top exposed. The length of the receiving groove 14 is greater than the length of the lock body 2, so that the lock body 2 can move along its length within the receiving groove 14.

[0032] The base 1 has two long sidewalls 12 each provided with a first locking part 15, and the lock body 2 has corresponding opposite sides provided with second locking parts 21. The base 1 has a first engaging structure 16, and the lock body 2 has a second engaging structure 22. When the lock body 2 slides forward to a preset position, the first engaging structure 16 and the second engaging structure 22 engage along the length of the base 1 to prevent the lock body 2 from longitudinally disengaging from the receiving groove 14; and the first locking part 15 engages with the second locking part 21 to prevent the lock body 2 from moving in the opposite direction. The position of the base 1 with the first locking part 15 can be deformed outward by external force, thereby releasing the engagement relationship between the first locking part 15 and the second locking part 21.

[0033] In this embodiment, the long sidewall 12 of the base 1 is provided with a first weakening hole 17 and a second weakening hole 18 arranged vertically. An arm beam 19 is formed between the first weakening hole 17 and the second weakening hole 18. A first retaining part 15 is provided on the arm beam 19. By bending the arm beam 19 outward by hand, it can be deformed, releasing the engagement between the first retaining part 15 and the second retaining part 21. The first weakening hole 17 and the second weakening hole 18 are both elongated holes (rectangular, elliptical, etc.) arranged along the length direction of the base 1. The second weakening hole 18 extends to the bottom wall 11, and the arm beam 19 extends with a hand-bending part 110. The hand-bending part 110 extends toward the second weakening hole 18 and is aligned with the bottom wall 11 of the base 1. The main function of the first weakening hole 17 and the second weakening hole 18 is to make the arm beam 19 easier to deform when subjected to external force. When it is necessary to remove the lock body 2, manually bend the position of the base 1 with the first locking part 15 outward to deform it (you can directly bend it with your fingers or use a simple tool to simultaneously pry open the two hand-bending parts 110 on both sides), thereby releasing the locking relationship between the first locking part 15 and the second locking part 21, so that the lock body 2 can be moved, and the first fitting structure 16 and the second fitting structure 22 can be separated, and the lock body can be taken out quickly and conveniently.

[0034] In this embodiment, the first clamping part 15 and the second clamping part 21 are oblique teeth with opposite tilting directions, which do not jam against each other in the forward direction but jam against each other in the reverse direction.

[0035] In this embodiment, the first fitting structure 16 is a groove formed on the side wall of the base 1, and the second fitting structure 22 is a block formed on the side wall of the lock body 2. When the lock body 2 moves along the length direction of the receiving groove 14, the block is inserted into the groove. The block and the groove are provided with mating inclined surfaces so that the block gradually tightens during insertion into the groove. There are multiple blocks and grooves, and they correspond one-to-one with each other. Multiple blocks are distributed on the long side wall 12 of the lock body 2, and multiple grooves are distributed on the long side wall 12 of the base 1. The inner wall surface of the base 1 is provided with 111 reinforcing ribs, and some of the 111 reinforcing ribs form the groove.
