5 results about "Vertical projection" patented technology

The invention relates to a mobile device. The mobile device comprises a middle frame structure and a screen module. The top of the middle frame structure protrudes inwards to form a protruding structure. The screen module comprises a glass panel and an LCD display module adhering to the bottom face of the glass panel. A black border of the LCD display module corresponds to the edge region of the glass panel. The edge region is matched with the protruding structure, and when the screen module and the middle frame structure are assembled, the vertical projection region of the black border is located in the vertical projection region of the protruding structure. By means of the technical scheme, the screen ratio of the mobile device can be increased, and use experience of a user can be improved.

The invention discloses a fast pyrolysis reactor which comprises a reactor body, a plurality of radiant tubes and a plurality of baffle plates, wherein the multiple radiant tubes are horizontally arranged at different heights in the reactor body in the same direction in a spacing manner; the radiant tubes on the adjacent height layers are staggered; the multiple baffle plates are arranged above the corresponding radiant tubes; vertical projections of the baffle plates cover the corresponding radiant tubes. The fast pyrolysis reactor provided by the invention is simple in structure and small in occupied area and can effectively pyrolyze powdered carbon-containing fuel.

The utility model relates to a non-anchor construction method for light steel structure floor adding reconstruction and aims to provide a construction method for light steel structure floor adding reconstruction without anchoring with the roof of an original house to ensure the integrity of the original roof structure. The non-anchor construction method comprises the following steps: (1) clearing the roof (1) to be smooth and clean; (2) determining the vertical projection area of a light steel structure (2) on the roof (1), and uniformly tiling an asphalt and coarse sand mixture (3) on the area; (3) placing a ground beam (4) on the asphalt and coarse sand mixture (3), and ensuring the smoothness of the ground beam (4); (4) mounting the light steel structure (2) on the ground beam (4); (5) plastering the surrounding of the ground beam (4) to realize seamless contact of the ground beam (4) and the roof (1). The light steel structure and the roof are firmly connected through the frictional resistance of the ground beam and the contact surface of the asphalt and coarse sand mixture, so that the non-anchor structure floor adding reconstruction is realized.
