Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, specifically relating to a glue-free assembled color box with built-in bayonet. Background Technology

[0002] In the packaging industry, especially in color box packaging, traditional assembly methods generally have some significant drawbacks, restricting efficiency, environmental friendliness, user experience, and cost control. Existing technologies mainly rely on the following methods and their inherent disadvantages: Heavy reliance on adhesive bonding: Currently, the assembly and fixing of most color boxes rely on various chemical adhesives. This method not only causes environmental pollution problems, such as the release of harmful substances like volatile organic compounds during adhesive production and use, but also makes the adhesive itself and its packaging waste difficult to dispose of, failing to meet increasingly stringent environmental requirements. Furthermore, the drying and curing time required for adhesives significantly slows down assembly efficiency, failing to meet the needs of rapid packaging. Applying adhesive also easily causes pollution and waste, affecting aesthetics and increasing material costs. Complex and inefficient assembly process: Traditional tongue, slot, or adhesive fixing methods often require multiple steps. The precise alignment requires skilled operators, and the assembly process is cumbersome and time-consuming, making it difficult to achieve rapid and efficient large-scale production or user self-assembly. Labor costs are high and prone to errors. Connection stability is insufficient or unreliable: relying solely on the tongue and slot structure, it is prone to loosening and deformation after external impact or long-term use, resulting in a loose box structure that affects protective performance and aesthetics. While glue bonding may initially provide stability, aging, moisture, or temperature changes can cause bonding failure. Disassembly is difficult and irreversible: once assembled, glued boxes are virtually impossible to disassemble without damage. This not only makes recycling and reuse difficult, leading to resource waste, but also makes it difficult for users to inspect or replace internal items. Even with partially plugged structures, there is often a lack of convenient and effective unlocking mechanisms, and forced disassembly can easily damage the structure. Utility Model Content

[0003] The purpose of this invention is to provide a glue-free assembled color box with built-in bayonet slots, aiming to solve the problems raised in the background art.

[0004] A glue-free assembly color box with built-in bayonet slots, comprising:

[0005] The mounting plate, two locking plates, two limiting plates, and a sealing plate are provided. The two locking plates and two limiting plates are bonded to the outer edge of the mounting plate, and the sealing plate is bonded to the outer edge of one of the limiting plates.

[0006] An assembly structure is located on the inner wall of two locking plates, comprising: a reset block, an inner buckle, a torsion bar, an assist block, a reset spring, a mounting groove, an unlocking groove, a mounting hole, and a sealing assembly. The mounting groove and unlocking groove are located on both sides of the outer wall of the locking plates, and the mounting hole is located on both sides of the outer wall of the limiting plate. The torsion bar is rotatably embedded in the inner wall of the mounting groove via a rotating shaft. The assist block is fixedly located on the outer wall of the torsion bar and slidably embedded in the inner wall of the unlocking groove. The reset spring is sleeved on the outer wall of the protruding end of the torsion bar. The inner buckle is embedded in the inner wall of the mounting hole and matches the torsion bar. The reset block is embedded in the inner wall of the mounting hole and matches the torsion bar. The sealing assembly is located on the inner wall of the sealing plate.

[0007] Furthermore, the sealing assembly includes a sliding groove, a limiting bracket, a locking tongue, a resistance button, and a support spring. The sliding groove is opened on the inner wall of the sealing plate, the limiting bracket is embedded in the inner wall of the sliding groove, the locking tongue is slidably embedded in the opening of the limiting bracket, the support spring is sleeved on the outer wall of the locking tongue, and the resistance button is fixedly set at the top center of the outer wall of the locking tongue.

[0008] Furthermore, the resistance button extends through the top of the outer wall of the sealing plate.

[0009] Furthermore, a lock hole is provided at the outer edge of one of the limiting plates, and the lock hole matches the lock tongue.

[0010] Furthermore, both locking plates have inner slots on their inner walls.

[0011] Furthermore, one end of the latch is inclined.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The assembly structure, through the precise cooperation of components such as the inner snap-fit, torsion bar, and reset block, achieves a purely mechanical locking connection. This not only eliminates environmental pollution problems caused by adhesives, such as the emission of volatile organic compounds, but also avoids the waiting time required for adhesive drying, significantly improving assembly efficiency and reducing material costs. Under the action of the reset spring, the torsion bar is firmly locked into the inner snap-fit, forming the main lock. At the same time, the reset block is immediately embedded in the mounting hole, providing auxiliary support and limiting the torsion bar. This dual locking mechanism effectively prevents the torsion bar from accidentally loosening due to vibration or external force during use, ensuring the rigidity of the overall structure and the long-term stability of the connection points. The assembly process is intuitive and smooth. The operator only needs to align the mounting hole on the limiting plate with the protruding end of the torsion bar and press the limiting plate to automatically complete the snap-fit ​​locking. The pressing action causes the torsion bar to overcome the spring force and lock into the inner snap-fit, while the reset block is in place. This one-step operation of alignment and pressing greatly simplifies the assembly steps, reduces the skill requirements of the operator, and significantly improves the convenience during production or use.

The locking plate 2 is then folded so that it forms a 90-degree angle with the mounting plate 1. The limiting plate 3 is pulled so that the mounting hole 302 aligns with the protruding end of the torsion bar 11. The limiting plate 3 is pressed so that the torsion bar 11 overcomes the supporting force of the return spring 13, causing one end of the torsion bar 11 to engage inside the inner buckle 10.
