Description

Technical Field

[0001] This utility model relates to the field of equipment box technology, specifically a high load-bearing, waterproof, dustproof and shockproof instrument and equipment box. Background Technology

[0002] Existing instrument and equipment cases typically use plastic or thin-walled metal as their main structural materials, which are insufficient to meet high load-bearing requirements. Especially in industrial or outdoor settings, the cases are prone to deformation under heavy equipment or external pressure, compromising equipment safety. Furthermore, traditional cases have poor sealing performance, with typically low waterproof and dustproof ratings, making it difficult to effectively prevent moisture and dust intrusion. This can lead to moisture damage or contamination of internal precision instruments, reducing their lifespan and accuracy. Current shock-absorbing designs often rely on a single foam lining, offering limited shock absorption. During transport or drops, these linings cannot adequately absorb impact, easily causing equipment damage. To address these issues, some cases on the market attempt to improve performance by increasing material thickness or using a single sealing ring. However, these improvements often increase case weight or cause seals to age and fail, making it difficult to simultaneously achieve a comprehensive performance that combines high load-bearing capacity, waterproofing, dustproofing, and shock resistance.

[0023] This embodiment provides a high load-bearing capacity, waterproof, dustproof and shockproof instrument and equipment case, the structure of which includes a case frame 1, a sealing system 2 and a shockproof system 3.

[0024] The enclosure frame 1, constructed from 6061-T6 aluminum alloy profiles and Q345B steel reinforcing corner brackets 13, is located on the external structure of the equipment enclosure and is designed to provide high load-bearing capacity to support heavy instruments and equipment. The aluminum alloy profiles are extruded to form the side and bottom plates, while the steel reinforcing corner brackets 13, after laser cutting and hot-dip galvanizing, are installed at the eight corners of the enclosure frame 1. The aluminum alloy profiles and steel reinforcing corner brackets 13 are fixedly connected using M8 bolts, which are evenly distributed on the contact surfaces between the corner brackets and the profiles, with torque control ensuring a secure connection.

[0025] The surface of the enclosure frame 1 is anodized to form an anti-corrosion layer, enhancing durability. Its advantage lies in the combination of aluminum alloy and steel design, which balances high load-bearing capacity and lightweight, solving the shortcomings of traditional plastic or thin-walled metal enclosures that are prone to deformation under heavy loads, while the anti-corrosion treatment extends service life.

[0026] A honeycomb support frame 11 is embedded inside the side and bottom plates of the enclosure frame 1. It is made of aluminum alloy profiles and features a biomimetic design to create a honeycomb structure, aiming to enhance the enclosure's bending strength. The reinforcing ribs 12 are strip-shaped aluminum alloy components, fixed to the inner surface of the honeycomb support frame 11 with M6 bolts. The bolts are evenly distributed to distribute stress. The honeycomb support frame 11 is connected using a combination of bolts and clips. The clips fit into the joints of the side plates, achieving modular assembly for easy assembly and maintenance. Its advantages include a significantly improved bending strength due to the honeycomb structure, and ease of maintenance due to the modular design, solving the problems of complex and difficult maintenance associated with traditional enclosure structures.

[0027] The sealing system 2 includes a silicone sealing strip 21, a drainage groove 22, and a labyrinth-style vent 23, which are installed in the joints and side walls of the enclosure frame 1 to achieve waterproof and dustproof functions. The silicone sealing strip 21 is made of high-temperature resistant silicone material and is distributed circumferentially along the sealing groove between the cover plate and side plate of the enclosure frame 1. It is fixed with 3M VHB tape to ensure a tight seal. The drainage groove 22 is located on the inner bottom of the bottom plate of the enclosure frame 1, and works in conjunction with an inclined guide plate 221 fixed above it. The guide plate is connected to the bottom plate at an angle by rivets to guide water flow out. The labyrinth-style vent 23 is embedded in the outer surface of the side wall of the enclosure frame 1 and fixed with screws. Its internal channel design extends the airflow path to block dust. Its advantages include a multi-level protection design that effectively prevents moisture and dust intrusion, a drainage groove and guide plate that work together to improve drainage efficiency, and a labyrinth-style vent that combines dustproofing and ventilation, solving the problems of traditional enclosure sealing failure and insufficient ventilation.

[0028] The shock absorption system 3 includes an EPE foam liner 31 and a suspended shock-absorbing bracket 32, installed inside the housing frame 1. It is designed to absorb impact forces during transportation or drops, protecting internal equipment. The EPE foam liner 31 is custom-molded using CNC engraving, closely adhering to the inner wall of the housing frame 1 and fitting against the equipment contact surface.

The suspended shock-absorbing bracket 32 ​​includes a spring 321 and a damper 322, fixed to the inner side of the bottom plate of the housing frame 1 with M6 bolts. The spring 321 and damper 322 are vertically arranged and connected to the bottom of the EPE foam liner 31 via snap-fit ​​connections, forming a suspended support structure. Its advantages include a composite shock absorption design that significantly improves impact absorption capacity, an anti-static coating that protects precision instruments, and solves the problem of poor shock absorption performance of traditional single foam liners. (Connection and signal transmission relationships are also discussed.) The enclosure frame 1 serves as the overall support structure. The honeycomb support frame 11, reinforcing ribs 12, and steel reinforcing corner pieces 13 are tightly connected by bolts and clips to form a high-load-bearing skeleton, ensuring uniform force transmission and avoiding localized stress concentration. The silicone sealing strip 21 of the sealing system 2 is tightly fitted to the sealing groove of the enclosure frame 1 via tape. The drainage channel 22 and the inclined guide plate 221 are connected by rivets to form a drainage channel. The labyrinthine vent 23 is fixed to the side wall with screws, ensuring coordination between sealing and ventilation. The EPE foam liner 31 of the shock absorption system 3 is bonded to the inner wall of the enclosure frame 1 with hot melt adhesive. The suspended shock-absorbing bracket 32 ​​is fixed to the base plate with bolts and connected to the EPE foam liner 31 via clips, forming a stable shock absorption transmission path and effectively protecting the internal equipment.

[0029] The working principle of this embodiment is based on structural optimization and functional integration. The enclosure frame 1, through the combination of aluminum alloy profiles and steel reinforcing corner pieces 13, combined with the honeycomb support frame 11 and reinforcing ribs 12, provides high load-bearing capacity, withstands external loads, and maintains structural stability. The sealing system 2 seals the gaps in the enclosure with silicone sealing strips 21, drainage channels 22 and inclined guide plates 221 guide water out, and labyrinthine vents 23 block dust while maintaining ventilation, ensuring waterproof and dustproof performance. The shock absorption system 3 wraps the equipment with EPE foam lining 31, and, in conjunction with the springs 321 and dampers 322 of the suspended shock-absorbing bracket 32, absorbs impact forces, protecting the internal equipment from vibration or drop damage. All components work together through bolts, clips, tapes, and rivets to form a high-load-bearing, waterproof, dustproof, and shockproof integrated protection system, suitable for the transportation and use of high-precision instruments and heavy equipment.
