[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, this utility model provides a double-layer shock-absorbing foam box for hardware parts, including an inner foam box 2, an outer foam box 1, and a shock-absorbing structure 4. The outer foam box 1 has an installation part 103 at its end. The inner foam box 2 is fitted into the outer foam box 1 through the installation part 103. The inner foam box 2 is connected to the outer foam box 1 through the shock-absorbing structure 4. The inner foam box 2 also has a detachable hardware parts placement structure 3.

[0023] In this embodiment, the shock-absorbing structure 4 between the inner foam box 2 and the outer foam box 1 can be composed of foam shock-absorbing columns 404, support columns 401, and connecting arms 402. This structure design allows the inner foam box 2 to move under external impact, reducing the direct impact on hardware. The foam shock-absorbing columns 404 act as a buffer, effectively absorbing vibration and impact forces.

[0024] The hardware placement structure 3 is connected to the shock absorption structure 4. The shock absorption structure 4 includes several support columns 401, several foam shock absorption columns 404, and connecting arms 402 connecting each foam shock absorption column 404. The connecting arms 402 are respectively connected to the base frame 403 and the support columns 401. The hardware placement structure 3 includes a first foam tray 302 and a second foam tray 303. The first foam tray 302 and the second foam tray 303 are respectively disposed on the base frame 403. The first foam tray 302 and the second foam tray 303 are each provided with a clamping plate 201 for connecting the inner foam box 2.

[0025] In this embodiment, the outer foam box 1 serves as the overall outer shell, providing protection and support. A base plate 203 connects to the support column 401 and mounting holes 102, enhancing stability and load-bearing capacity. The inner foam box 2 is fitted inside the outer foam box 1 and connected to it via a shock-absorbing structure 4, reducing the impact of external impacts on the internal hardware. The inner foam box 2 contains a detachable hardware storage structure 3, facilitating the classification and organization of hardware.

[0026] A shock absorption system is formed by setting up support pillars 401, foam shock-absorbing columns 404, and connecting arms 402. When external forces are applied, the foam shock-absorbing columns 404 deform, thereby absorbing and dispersing the impact force. The foam shock-absorbing columns 404 absorb vibrations at key locations, allowing the inner foam box 2 to have a certain floating space relative to the outer foam box 1, reducing direct contact and vibration transmission. The cooperation between the positioning groove 204 and the connecting arm 402 ensures the stability of the shock absorption structure 4, making the hardware less prone to movement during transportation and further improving safety. The clamp 201 connects to the inner foam box 2 and is used to fix the first foam tray 302 and the second foam tray 303, preventing damage to the hardware during transportation and facilitating disassembly and replacement.

[0027] Furthermore, the bottom of the outer foam box 1 is also provided with a base plate 203, the base plate 203 is connected to the support column 401, and the bottom of the outer foam box 1 is provided with several mounting holes 102, wherein the base plate 203 is provided with several connecting rods 202 that are correspondingly inserted into the mounting holes 102, and the connecting rods 202 are respectively connected to each of the foam shock-absorbing columns 404.

[0028] Multiple mounting holes 102 are provided around the bottom of the outer foam box 1. Connecting rods 202 pass through these mounting holes 102 and are connected to the foam shock-absorbing columns 404 one by one. The connecting rods 202 connect the base plate 203 and the foam shock-absorbing columns 404 to form a robust connection assembly, enabling each shock-absorbing column to effectively support a portion of the weight of the foam box and work together to distribute pressure when subjected to external impact.

[0029] The foam shock absorber column 404 can absorb impact force when affected by its elasticity and deformation capacity. At the same time, since the connecting rod 202 extends from the base plate 203 to the shock absorber column, when the external impact reaches the base plate 203, the force can still be effectively dispersed by connecting the foam shock absorber column 404, thereby reducing the possibility of the impact force being transmitted to the inner foam box 2 and its hardware.

[0030] Furthermore, the inner foam box 2 has an installation track 205 and a positioning groove 204 on its side wall. The positioning groove 204 is connected to the connecting arm 402, and the installation track 205 is connected to the clamping plate 201. The clamping plate 201 has an installation plate 301 on one side for fixing the first foam plate 302 and the second foam plate 303.

[0031] The mounting rail 205 provides a sliding base for the clamp 201, allowing the clamp 201 to be vertically mounted on the side wall of the inner foam box 2. The positioning groove 204 is used to install the connecting arm 402. When the connecting arm 402 is inserted into the positioning groove 204, the position of the clamp 201 can be fixed to prevent it from shifting during transportation or use.

[0032] Furthermore, there are two of the first foam tray 302 and the second foam tray 303, and both the first foam tray 302 and the second foam tray 303 are provided with placement slots 304 for placing hardware parts.

[0033] The shape and size of the placement groove 304 are designed according to the characteristics of the hardware, which can effectively wrap and fix the hardware, ensuring that it is not easy to slip or fall off.

[0034] The shape and size of the placement slot 304 are designed according to the characteristics of the hardware, effectively wrapping and securing the hardware to ensure it does not easily slip or fall. Different foam trays can be selected for placement to flexibly accommodate hardware of different sizes and shapes.

[0035] Furthermore, the side wall of the outer foam box 1 is provided with several mounting slots 101 for mounting foam shock-absorbing columns 404, and each mounting slot 101 corresponds to a foam shock-absorbing column 404. The mounting slots 101 on the side wall of the outer foam box 1 provide a dedicated space for precisely fixing the foam shock-absorbing columns 404. By using multiple mounting slots 101, the number of foam columns can be flexibly reduced or increased as needed, thereby adjusting for different item weights and volumes.

[0036] Each damping column is connected to its corresponding mounting slot 101 in a one-to-one manner to ensure the stability of the damping column's installation position. When the foam damping column 404 is installed in the slot, it can effectively prevent functional failure due to improper positioning during use.

[0037] Furthermore, the first foam tray 302 is an isosceles triangle, while the second foam tray 303 is a right-angled triangle. The first foam tray 302 provides a wider base and a symmetrical structure, making it relatively stable when placed, effectively supporting heavier or larger hardware and reducing pressure concentration at the bottom under load. The second foam tray 303 is designed to fit flush against other surfaces, saving space, and is suitable for following the corners or recesses of containers, maximizing space utilization.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
