Description

Technical Field

[0001] This utility model relates to a bag lock assembly fixing mechanism. Background Technology

[0002] Most locks on bags are recessed and installed in grooves in the bag panels or shell. They are usually fixed by rivets or screws, which requires manual operation, is time-consuming and labor-intensive, and cannot be automated on a production line. Summary of the Invention

[0003] This utility model provides a luggage lock assembly fixing mechanism, which has the advantages of simple structure, quick installation and automated assembly line assembly.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a luggage lock assembly fixing mechanism, including a lock assembly mounting groove on the luggage shell, an upper lock body, and a lower lock shell. The upper lock body is provided with an upper lock panel and a recessed lock cylinder shell. The length and width dimensions of the upper lock panel are both larger than the length and width dimensions of the lock assembly mounting groove. The length and width dimensions of the recessed lock cylinder shell are both smaller than the length and width dimensions of the lock assembly mounting groove. The length and width dimensions of the upper edge of the lower lock shell are both larger than the length and width dimensions of the lock assembly mounting groove. The lock cylinder shell is provided with a connecting plate, a retaining spring, and a fixing plate. One side of the connecting plate is connected to the recessed lock cylinder shell, and the other side of the connecting plate is connected to the fixing plate. The retaining spring is clamped and fixed between the connecting plate and the fixing plate. The retaining spring is provided with a retaining connector. The inner side wall of the lower lock shell is provided with a retaining protrusion. The retaining connector and the retaining protrusion engage and engage to fix the lock cylinder shell. The upper lock body and the lower lock shell are respectively attached to both sides of the lock assembly mounting groove on the box shell, and the box shell, upper lock body, and lower lock shell are clamped and fixed to the box shell.

[0005] The beneficial effects of this utility model are as follows: By using an upper locking panel whose length and width are both larger than the length and width of the lock assembly mounting groove and the upper edge of the lower lock shell, the two sides of the lock assembly mounting groove on the box shell are clamped together. Then, through the snap-fit ​​between the lower lock shell and the snap-fit ​​spring, and the snap-fit ​​between the connecting plate and the recessed lock cylinder shell, the effect of nail-free installation and quick assembly of the box shell surface is achieved. The specific installation process is as follows: First, the snap-fit ​​spring is installed between the connecting plate and the fixing plate. Then, the recessed lock cylinder shell is passed through the lock assembly mounting groove. Then, the connecting plate, along with the snap-fit ​​spring and the fixing plate, is fixedly connected to the recessed lock cylinder shell. Finally, the lower lock shell is snapped on. The snap-fit ​​joint on the snap-fit ​​spring and the snap-fit ​​protrusion on the inner side wall of the lower lock shell are engaged to fix the lower lock shell and the upper lock body together. The entire assembly process is quick and does not require manual rivet or screw installation, and can achieve automated assembly line assembly.

[0006] Furthermore, the connecting plate is provided with a hook, and the recessed lock cylinder shell is provided with a slot. The hook and the slot engage in a snap-fit ​​relationship, which can achieve the effect of quick assembly and also achieve the effect of connection without rivets or screws.

[0007] Furthermore, the connecting plate is provided with threaded holes, and the fixing plate is provided with screws. The screws are threadedly engaged with the threaded holes to connect and fix the connecting plate and the fixing plate. The fixing of the connecting plate and the fixing plate can be pre-operated by pre-fixing the snap ring between the two, realizing the integrated pre-connection of the three small components of the connecting plate, the fixing plate and the snap ring, which is more convenient for subsequent installation on the bag.

[0008] Furthermore, the snap-fit ​​protrusion is an oblique protrusion structure, and the snap-fit ​​connector of the snap-fit ​​spring plate cooperates with the oblique surface of the snap-fit ​​protrusion. The oblique protrusion structure can achieve a clamping effect when the shell plates between the upper lock body and the lower lock shell are of different thicknesses. That is, the size of the gap between the upper lock body and the lower lock shell is affected by the different positions of the snap-fit ​​connector of the snap-fit ​​spring plate on the oblique surface of the snap-fit ​​protrusion, which can be used for shell plates of different thicknesses.

[0009] Furthermore, the snap-fit ​​connector of the snap-fit ​​spring is toothed, which can achieve a more secure snap-fit ​​effect.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
