It can be widely used in the fabric preparation of various bag and luggage products such as high-end trolley cases, backpacks, outdoor bags, and briefcases, and can also be extended to outdoor products, protective equipment, and other fields, possessing significant industrial application value and market prospects.

This utility model relates to the field of all-terrain vehicle canopy technology, specifically to a detachable structure for an all-terrain vehicle canopy. It includes four threaded rods connected to an external vehicle frame via threads. Each threaded rod has a limiting plate at its top, with fixing holes along its edge and bolts forming a double anti-loosening connection with the vehicle frame. A plug rod is located at the top of the limiting plate, engaging with the bottom of the front and rear support frames via a plug-in connection and securing it with bolts. The front support frames are connected by a first support crossbar to form a front support frame, and the rear support frames are connected by a second support crossbar to form a rear support frame. The front and rear support frames are connected to support longitudinal rods via plugs to form a complete canopy frame. This structure achieves overall detachability of the canopy through modular design, and the basic connection points are non-welded, facilitating partial replacement and maintenance. This avoids damage to the vehicle frame caused by traditional welding repairs, improving maintenance efficiency and ease of use.
