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.

This invention discloses a seismic bearing for building engineering in the field of seismic bearing technology, comprising a frame, a pressure rod slidably connected to the top of the frame, a support plate fixedly connected to the top of the pressure rod, a buffer spring for resetting the pressure rod inside the frame, and a buffer resetting assembly inside the frame. The buffer resetting assembly is used to absorb the potential energy of the buffer spring after the pressure rod is compressed into the frame by an external force, so that the pressure rod can be buffered during resetting. By using the buffer resetting assembly, when the support plate is subjected to pressure, the buffer spring will push the pressure rod upward again under the action of elastic potential energy. At this time, the buffer resetting assembly will limit the resetting speed of the pressure rod, so that the pressure rod rises slowly, and the elastic potential energy of the buffer spring is released slowly. The purpose of this is to absorb the elastic potential energy of the buffer spring through the buffer resetting assembly, so that the pressure rod can be buffered during resetting.

This utility model relates to the field of orthopedic fixation splint technology, and discloses a malleable thumb fracture fixation splint, including a finger mold. A protective pad is placed inside the finger mold. A silicone layer is fixedly disposed on the upper end of the protective pad. An odor-removing layer is fixedly connected to the lower end of the silicone layer. A cooling gel layer is fixedly connected to the lower end of the odor-removing layer. Two mounting plates are fixedly disposed on one side of the finger mold. Triangular locking blocks are fixedly disposed on one side of the two mounting plates. Connecting pins are rotatably disposed inside one side of the two mounting plates. Buckles are rotatably disposed on the outer walls of the two connecting pins. In this utility model, the splint allows for quick replacement of the protective pad, reduces the temperature around the thumb, alleviates the patient's thumb's stuffiness, and facilitates quick putting on and taking off by medical staff or patients. It prevents the device from falling off or shifting during patient activity, thus avoiding secondary injury.
