Disclosed are a holographic reconstructing device and its application for portable electronic products. The holographic reconstructing device includes a compound hologram (9), a hologram seat (91), and a rebuilding light source (12). The compound hologram (9) is a flat-disk contour and disposed on the hologram seat (91). The rebuilding light source (12) is an LED and disposed under the hologram seat (91). The LED takes advantage of a small magnitude, less electricity consumption, simplified components, and a narrow bandwidth to definite a rebuilt image. The application of the flat-disk compound hologram is in a smooth-lying placement while reconstructing, which preferably occupies less space and facilitates user's observation as the rebuilt image is placed on the top of the compound hologram. The embedding of the holographic reconstructing device into the products would not affect the dimension of the products, thereby exhibiting realistic images on an individual space and forming a strong visual, clear impression, and a newly entertaining effect.

The invention discloses a hinging device for a refrigerator. By the hinging device, a door body of the refrigerator can be pivotally connected to a box body; and the hinging device comprises a fixed plate, a connecting piece and a pivot shaft, wherein the fixed plate is connected to the box body; the connecting piece is arranged along the front and back directions; one end of the connecting piece is fixed on the fixed plate while a threaded hole of which the upper part and the lower part pass through the other end of the connecting piece is formed at the other end of the connecting piece; the connecting piece is formed in the dead center of the fixed plate; the pivot shaft is extended along the vertical direction; an outer thread matched with the threaded hole is formed at the upper end of the pivot shaft; and the lower end of the pivot shaft is rotatably connected to the door body. According to the hinging device for the refrigerator, the hinging device is in an invisible state from the appearance of the refrigerator, so that a hinge cover in the traditional process can be saved, the height of the door body is consistent with that of the box body; and therefore, the refrigerator is attractive in whole shape and has a simple structure. In addition, by using the hinging device, the requirement on opening the door from the left side or the right side can be met. The invention also discloses the refrigerator having the hinging device.

The invention relates to a children umbrella handling trolley. A trolley frame comprises a first front frame, a second front frame, a first push rod which is rotatably connected with the first front frame and a second push rod which is rotatably connected with the second front frame, wherein the lower end parts of the first push rod and the second push rod are provided with a first front frame connecting part and a second front frame connecting part respectively which protrude towards the upper side when the trolley frame is in an unfolding position; the upper end parts of the first front frame and the second front frame are rotatably connected with the first front frame connecting part and the second front frame connecting part respectively and correspondingly, and the central lines of upper rod bodies of the first front frame and the second front frame are positioned above lower rod bodies of the first push rod and the second push rod correspondingly. When the trolley is in the unfolding position, observing from the right front side, the upper end parts of the first front frame and the second front frame form a step part respectively on the first push rod and the second push rod. The step parts can be shielded by a sail, thus lines from top to bottom of the first front frame and the second front frame from a rotating connecting point are smooth to ensure that the model is simple and beautiful, and the defects which cannot be overcome by the model are eliminated.

The invention relates to a bamboo rod system structure pedestrian arch bridge which comprises a bridge pier, a bamboo arch ring, a bamboo bridge panel, a bamboo bridge panel support and a bamboo handrail, wherein the bamboo arch ring comprises at least three parallel bamboo arch ring wattles, connecting element bolts and a bamboo connecting system beam; the heads and the tails of the bamboo arch ring wattles are connected by bolts, and the middles are also connected by bolts; the bamboo connecting system beam penetrates through clearances among the end parts of all the bamboo arch ring wattles and connects all the independent bamboo arch rings together; the bamboo arch ring is fixedly connected with the bridge pier by a steel connecting element; the bamboo bridge panel support is fixed tothe side surface of the bamboo arch ring; a vertical rod of the bamboo handrail and an outside guard board of the arch ring are fixed to the arch ring by bolts; and the bamboo bridge panel is fixed to the bamboo bridge panel support. The bamboo rod system structure pedestrian arch bridge of the invention has light self weight and small horizontal thrust and has the characteristics of low carbon, environmental friendliness, material saving, high processing speed of members, high construction and installation speed, and the like.
