The present application relates to the technical field of automotive interior technology, and relates to a hidden folding damping hinge and a hinge-equipped automobile seat table board, which comprises a bridging shell, Y-shaped damping leaf springs, a split pin, a plug, a connecting plate, a buffer pad and a mandrel. The bridging shell is internally provided with two groups of Y-shaped damping leaf spring positioning grooves, each group of the Y-shaped damping leaf spring positioning grooves is internally fitted with at least two Y-shaped damping leaf springs, the plug is mounted at the end of the Y-shaped damping leaf spring positioning groove, the connecting plate is rotationally arranged on the outer side of the Y-shaped damping leaf spring positioning groove, one end of the buffer pad is abutted against the bridging shell, and the other end of the buffer pad is abutted against the connecting plate, the mandrel penetrates through the connecting plate and the bridging shell, and forms a friction pair with the Y-shaped damping leaf springs to generate damping force. The hinge of the present application improves the stability of the table board through the damping structure and the limiting mechanism, and improves the overall appearance through the hidden layout.

The invention discloses a convenient folding scooter for old people. The convenient folding scooter comprises a bogie, a front frame and a rear frame, by means of the collaborative folding structure, synchronous folding of the frame, the steering handlebar and the cushion frame is achieved, step-by-step operation is not needed, integral folding can be triggered only by pulling the control handle, the operation steps are reduced to one, the front frame and the cushion frame of the convenient and fast folding old people mobility scooter get close synchronously during folding, the whole frame is folded downwards along the hinged position, and the operation is convenient and fast. The size is obviously reduced after folding compared with an unfolded state, home storage and automobile transportation are facilitated, the application scenes cover home riding instead of walk, short-distance travel and the like, and the high practical value is achieved.

This utility model relates to the field of machinery technology for oil drilling engineering, and particularly to a multi-directional adjustment device for a drill bit and a drill bit itself. The multi-directional adjustment device includes a lifting and rotating mechanism, a telescopic mechanism, a C-frame, and an adjustment assembly connected to the top of the C-frame. The telescopic mechanism includes a first telescopic assembly, a connecting assembly, a second telescopic assembly, and a telescopic drive assembly, all hinged sequentially along its length. A pipe handling device is mounted on the C-frame. The lifting and rotating mechanism drives the telescopic mechanism to vertically lift and rotate, while the telescopic drive assembly drives the first and second telescopic assemblies to expand or retract, allowing the pipe handling device to move to the drill bit position. The adjustment assembly adjusts the horizontal angle of the pipe handling device. The multi-directional adjustment device enables flexible and precise adjustment of the pipe handling device in multiple directions, and its overall structure is simple, using few parts and resulting in low cost.

The utility model belongs to the field of outdoor camping supplies, concretely relates to a folding portable bonfire platform, including a plurality of folding frame assemblies that are stacked from bottom to top, a plurality of insertion holes are formed on each folding frame assembly, and the insertion holes of the stacked folding frame assemblies are correspondingly arranged, and the insertion rods pass through the insertion holes to connect the folding frame assemblies. When not in use, the folding frame assemblies are separately arranged, the folding frame assemblies can be folded to reduce the occupied space, when in use, the folding frame assemblies only need to be opened, and the folding frame assemblies can be fixed through the insertion rods, the installation and disassembly are very convenient, and no complex installation steps are needed. In addition, the number of folding frame assemblies can be selected according to actual use, the number of folding frame assemblies determines the height of the final bonfire platform, and the use is flexible.
