The invention discloses a lower discharging foaming device which comprises a movable base, a lower discharging foaming device, a lower discharging foaming device and an upper discharging foaming device, and a walking wheel set is arranged at the bottom of the movable base; the vertical bracket is fixedly mounted on the movable base; the variable-length flow guide mechanism comprises a flow guide channel which is arranged in an inclined mode and is telescopic in length, and the higher end of the flow guide channel is connected with the upper portion of the vertical support; the length adjusting driving mechanism is mounted on the vertical bracket, is in transmission connection with the movable part of the length-variable flow guide mechanism, and is used for driving the movable part to move so as to change the effective length of the flow guide channel; and the buffer mechanism is arranged in the groove of the flow guide groove channel and is used for providing damping buffer when the foaming profile slides down along the groove.

The application relates to the technical field of tunnel lighting, in particular to a tunnel lighting device utilizing sunlight refraction, which comprises a turning pipe, an inner light guide pipe, an outer light guide pipe and the like. The turning pipe is a pipeline structure with a vertical bend and is used for changing the light transmission direction, the horizontal end of the turning pipe is connected with the inner light guide pipe, and the vertical end of the turning pipe is connected with the outer light guide pipe. The application does not need photoelectric conversion in the whole process, directly uses natural light for illumination, has no power consumption, no carbon emission and no battery replacement problem, and has low operation cost. A large-diameter light collecting cover is used to cooperate with a large-pipe-diameter installation pipe to improve the initial light collecting area. The light is gathered into a collimated light beam through a first focusing lens and a collimating lens, so that the divergence loss is reduced.

This utility model discloses an intermediate standard and an automated scanner calibration system. The intermediate standard is used in the calibration of 3D scanners. The intermediate standard includes a main body and recognition heads. An annular recognition area is provided on the main body. Several recognition markers are provided within the annular recognition area for recognition by a scanner located above the main body and a tracker located at any point around the main body. Several recognition heads are provided on the main body, protruding from the main body in the height direction. Several recognition markers are provided on the outer surface of each recognition head, and the tracker can recognize some of the markers on the recognition heads at any point around the main body. The design of the annular recognition area and recognition heads reduces the limitations on the placement of the tracker and scanner in the calibration process, making the formulation of the automated calibration process more flexible and improving the applicability and versatility of the intermediate standard and this calibration system.

The utility model discloses a knob type electronic gear shifting manipulator, and belongs to the technical field of automobile control. The automobile gear shifting device comprises a seat body used for being connected with an automobile and a gear shifting assembly, the gear shifting assembly is connected with the seat body and comprises a PCB, a turning cover and a rotary pressing unit, the rotary pressing unit comprises a rotating shaft, a P-gear button and a clamping piece, the rotating shaft and the P-gear button are arranged on the PCB, the clamping piece is arranged on the turning cover, the axis of the rotating shaft is parallel to the PCB, and the clamping piece is movably clamped to the rotating shaft. The turning cover can rotate around the rotating shaft so that the P-gear button can be pressed and triggered. According to the knob type electronic gear shifting manipulator, the automobile P gear can be integrated to the knob type electronic gear shifting manipulator, a gear shifting structure is simplified, the situation that the P gear is switched by mistake can be effectively avoided, and the control safety is improved.
