Description

Technical Field

[0001] This utility model relates to the field of high-strength die-cast aluminum enclosure technology, and in particular to a high-strength die-cast aluminum enclosure. Background Technology

[0002] High-strength die-cast aluminum enclosures are important structural components in modern industrial equipment and are widely used in communication equipment, power electronics, industrial control, and other fields. They are made of high-strength aluminum alloy through die casting and have advantages such as light weight, high strength, and corrosion resistance, which can meet the needs of use under complex working conditions. With the increasing trend of modular development of industrial equipment, the convenience and reliability of enclosure expansion and connection have become key design indicators. Traditional enclosure structures often have problems such as inconvenient connection and complicated operation when realizing functional expansion. A new connection solution is needed to improve installation efficiency and maintenance convenience. Therefore, the development of high-strength die-cast aluminum enclosures with quick connection and disassembly functions has important engineering application value.

[0003] In existing technologies, the expansion connection of die-cast aluminum housings mainly adopts bolt fastening or pin positioning. Bolt connection uses threaded engagement to fix the housing to the expansion component, requiring multiple tightening operations with tools. Although the connection is reliable, the installation efficiency is low. Pin connection relies on precision-machined positioning holes and pins for alignment, and is fixed with spring clips or elastic pins. This structure requires high machining accuracy and is prone to wear and loosening after long-term use. In addition, some designs use slide rail guidance with manual locking mechanism, which simplifies the installation steps, but still requires multiple operations to complete the connection. These technical solutions have certain limitations in terms of connection reliability and ease of operation.

[0004] The main problem with existing technologies is that traditional expansion connection methods require complex alignment and auxiliary tools, resulting in low installation efficiency. Specifically, this manifests in the following ways: multiple connection points need to be precisely aligned during the connection process, making operation difficult; special tools must be used for tightening or unlocking, increasing operational complexity; and repeated adjustments are often required when connecting multiple components, which is time-consuming and labor-intensive. These problems seriously affect the efficiency and convenience of equipment expansion, especially in application scenarios where frequent replacement or addition of functional modules is required, thus restricting the overall efficiency of equipment use. Therefore, a rapid connection solution that does not require complex alignment and auxiliary tools is needed to solve this problem. To this end, a high-strength die-cast aluminum housing is proposed to address the above issues. Utility Model Content

[0009] The quick-release assembly includes a hollow column and a rotating rod. The outer wall of the rotating rod is rotatably connected to the inside of the hollow column, and the outer wall of the hollow column is fixedly connected to the inside of the upper housing.

[0010] As a further description of the above technical solution:

[0011] One end of the rotating rod is fixedly connected to a rotating block, and the other end of the rotating rod is fixedly connected to a locking block.

[0012] As a further description of the above technical solution:

[0013] A limiting ring is fixedly connected to the outer wall of the rotating rod, and the outer wall of the limiting ring is slidably connected inside the hollow column.

[0014] As a further description of the above technical solution:

[0015] A second spring is provided on the outer wall of the rotating rod. One end of the second spring is fixedly connected to the inner wall of the hollow column, and the other end of the second spring is fixedly connected to the outer wall of the limiting ring.

[0016] As a further description of the above technical solution:

[0017] The lower housing has a groove inside, and the outer wall of the rotating rod is rotatably connected to the inside of the lower housing.

[0022] This utility model has the following beneficial effects:

[0023] 1.

[0024] 2. In this utility model, by rotating the rotating block, the rotating rod rotates inside the hollow column. At this time, the locking block is released from the restriction block and disengages from the lower box through the opening. Then, the rotating block is pulled, causing the rotating rod and the limiting ring to squeeze the second spring. At this time, the rotating rod drives the locking block to slide into the hollow column. Then, the upper box is pulled upward, and the upper box and the lower box are separated, thereby achieving the effect of quickly disassembling the upper box and the lower box. This solves the problem that traditional box disassembly requires tools and is cumbersome, resulting in low maintenance efficiency, and improves the convenience of box disassembly.

[0037] Working Principle: When expanding the high-strength die-cast aluminum housing with external equipment, the external connector is inserted into the connecting slot 8 of the lower housing 1. During insertion, the external connector first contacts the inclined surface of the trapezoidal block 6. Under the action of the thrust, the trapezoidal block 6 drives the limiting block 5 to slide along the inner wall of the lower housing 1, while simultaneously compressing the spring 7. When the external connector is fully inserted, the elastic restoring force of the spring 7 pushes the limiting block 5 to reset, causing the trapezoidal block 6 to engage in the corresponding slot of the external connector, achieving automatic locking. This process is repeated for the upper housing. When disassembling and separating the upper body 2 and the lower box 1, the rotating block 11 is rotated to make the rotating rod 10 rotate inside the hollow column 9. At this time, the locking block 12 is released from the restriction block 15 and is released from the lower box 1 through the opening 16. Then, the rotating block 11 is pulled to make the rotating rod 10 and the limiting ring 13 squeeze the spring 17. At this time, the rotating rod 10 drives the locking block 12 to slide into the hollow column 9. Then, the upper box 2 is pulled upward to separate the upper box 2 and the lower box 1, thereby achieving the effect of quickly disassembling the upper box 2 and the lower box 1.
