This application relates to a portable fan that can be used as both a table clip and a table stand, comprising: a fixed bracket for connecting a fan head assembly, a fixed ring connected to the fixed bracket, and a replacement bracket connected to the fixed ring. The fixed ring has mounting holes, and fixing holes are respectively provided on both sides of the fixed ring and one end of the replacement bracket. A connecting rod is provided on the fixed bracket corresponding to the fixing holes. After the end of the replacement bracket passes through the mounting hole, the connecting rod of the fixed bracket passes through the fixing holes of the fixed ring and the replacement bracket, thereby realizing the replaceable locking and fixing of the replacement bracket. The method provided by this application embodiment allows users to replace the replacement bracket according to the usage needs of different scenarios, thereby satisfying the needs of placing or clamping the portable fan, thus realizing the function of the fan and broadening the applicable scenarios of a single portable fan.

This utility model relates to the field of drone remote control technology, specifically a folding joystick for a drone remote control. It includes a remote control housing with a first control slot and a second control slot on its top surface. A first flight control mechanism is movably installed inside the first control slot, and a second flight control mechanism is movably installed inside the second control slot. The first and second flight control mechanisms have identical structures and are arranged perpendicularly to each other. A joystick fixing component is provided on one side of the storage slot. When the joystick is folded and installed inside the storage slot, the locking pin and locking hole can secure the joystick inside the storage slot, thus avoiding the risk of breakage due to the joystick accidentally detaching from the storage slot during remote control transport.

The utility model discloses an intelligent device, which is used for solving the technical problem that the existing sound box main body and the sound post need to be assembled when being used, so that the use is inconvenient. The sound box comprises a sound box main body and sound columns. The outer side surface of the sound box main body is provided with a storage groove used for storing the sound post, the storage groove is internally provided with an automatic overturning driving assembly, and the automatic overturning driving assembly is connected with the sound post. The sound post can be driven by the automatic overturning driving assembly to rotate relative to the storage groove so as to be stored in the storage groove or leave the storage groove. In the above design, the sound post is integrated on the sound box main body, and the sound box main body is provided with the accommodation groove for accommodating the sound post, so that a user can control the automatic overturning driving assembly to drive the sound post to rotate relative to the accommodation groove, thereby realizing the automatic accommodation or use function of the sound post, and effectively improving the use convenience of the sound box. And the use experience of the user is improved.

The invention provides a design method of a steel structure spiral staircase, and relates to the field of building steel structure engineering, and the method comprises the steps: building a spiral staircase space line model through computer software, and discretizing and importing a finite element program; defining a bearing system composed of the internal rotation steel beam, the external rotation steel beam and the step steel beam; applying a handrail load, a step load and a temperature effect; setting boundary conditions of the fixed support; executing deformation, internal force and stress analysis; internal and external rotation steel beams are designed by adopting a box-shaped section according to a stress result, and a rectangular steel pipe step beam is used for providing plane external support; arranging riffled plates and rib plates on the lower flanges of the steel beams based on the deformation data; section steel is pre-embedded in the concrete platform according to the internal force of the support, and rigid connection of the ends of the steel beams is achieved. According to the method, the limitation of a traditional graph set on the size of the spiral staircase is broken through, and the requirements for strength, stability and deformation control are met at the same time through finite element full-process driving design under the condition that intermediate supports are cancelled.
