The invention discloses a novel whole set structure of a door plate, a door sleeve and hinges. The novel whole set structure comprises a right side frame, a left side frame, an upper side frame and a door plate body. The right side frame is mainly composed of a right outer frame body, a right frame plate and a right inner frame body. The left side frame is mainly composed of a left outer frame body, a left inner frame body and a left frame plate. The upper side frame is mainly composed of an upper outer frame body, an upper frame plate and an upper inner frame body. The door plate body is mainly composed of surrounding columns, side seal plates, a face plate, a core plate and end seal plates. Hinge assemblies are arranged at the upper and lower ends between the door plate body and the left side frame. According to the structure, the large number of labor costs is saved, the large amount of mounting time is saved, and excessive waste of materials is avoided; the strength of the door plate is increased, the cost is reduced, and mounting is better facilitated; the connecting mode of the door plate and the door frames is concealed, and overall attractiveness is achieved; and the structure utilizes a novel assembling mode, the labor intensity of workers and the technical requirement are reduced, the strength of the door structure is strengthened, and the production period is shortened.

A deformable plastic check valve for sewer pipe is prepared from the elastic plastics resisting to ageing, acid and alkali, and has the elastic lower mouth with honeycomb structure, closed top end with a pull-up ring, and reinforcing rings on its external circumference. When water is flushed down, it isdeformed from draining the water and then elastically restored to its original shape. Its advantage is high sealing performance.

The invention provides a novel hanging type infusion stand, in particular to a novel hanging type infusion stand which is medical, slidable and telescopic and is provided with a slide locking function. A power source data line is inlaid in a hollow tubular hanging rod, medical instruments such as an infusion monitor and an infusion pump can be assembled outside the hanging rod, and infusion height and ground clearance can be optionally adjusted by telescopic length of the hanging rod. The novel hanging type infusion stand with a double-spring structure is simple in structure and ingenious in design, the advantage of the hanging type infusion stand that space is saved is kept while the problem about mounting of electricity-dependent medical instruments is solved. Medical environment is effectively improved, and enormous economic and social benefits are achieved.

The invention discloses a motorcycle rear fork anti-theft lock. A motor driving mechanism is arranged in a motorcycle rear fork anti-theft lock shell; one end of a lead screw is connected with a motor shaft; the other end of the lead screw is rotationally arranged on a shaft sleeve; a driving block is rotationally connected to the lead screw driven by using a direct-current motor; a lock rod is in sliding fit with a slip way; a connecting rod is hinged between the driving block and the lock rod; the left and the right sides of the lead screw are provided with locking and opening limiting switches respectively; the upper end of a pull rod which is fixedly connected to a mechanical lock core opened by using an external extending key extends into a hole in an emergency screw rod; and the inner end of the emergency screw rod is rotationally connected to the shaft sleeve from outside to inside. Due to the adoption of the motorcycle rear fork anti-theft lock, technical unlocking and violent unlocking can be prevented; and the motorcycle rear fork anti-theft lock has the characteristics of reasonable structure, easiness and convenience in operating and high anti-theft performance.

The invention discloses a mono-crystalline silicon double-sided solar cell. A front texturing morphology structure (1), a front PN emitter junction (2), a front passivated anti-reflection medium layer (3) and a front electrode (4) are sequentially formed on the front of a mono-crystalline silicon substrate (100). A back texturing morphology structure (5), a back surface field (6), a back passivated anti-reflection medium layer (7) and a back electrode (8) are sequentially formed on the back of the mono-crystalline silicon substrate. The solar cell is characterized in that the back texturing morphology structure (5) is a platform type texture surface, and platform structures (5a) are distributed on the mono-crystalline silicon substrate in a scattered, or tiled, or partially scattered, partially tiled, partially connected and partially overlapped way. The invention further discloses a preparation method of the mono-crystalline silicon double-sided solar cell. The minority carrier surface recombination and optical absorption characteristics of the double-sided solar cell are optimized, and the efficiency of quantum conversion is improved.

The invention relates to a poly(p-phenylene benzobisoxazole) (PBO) composite fiber containing nano-TiO2 preparation method, comprising the following steps: dissolving 4,6-diaminoresorcinol hydrochloride and terephthalic acid and a certain number of phosphorus pentoxide in equal molar ratio in polyphosphoric acid, removing hydrogen chloride gas, heating and polymerizing to obtain poly(p-phenylene benzobisoxazole), then adding poly(p-phenylene benzobisoxazole) and phosphoric acid solution containing nano-TiO2 in a double-screw extruder and obtaining PBO composite fiber containing nano-TiO2 by dry-jet wet spinning; the invention uses nano-TiO2 particles with ultraviolet shielding property and utilizes the strong shearing and high effective blending of the double-screw extruder to prepare thecomposite fiber; compared with pure PBO fiber, the ultraviolet aging resistance property is effectively improved while the mechanical properties are not reduced.

The invention provides a preparation method and a use method of high-concentration silver nano-wire stabilized ink used for storage. The silver nano-wire stabilized ink with the solid content of 0.05-10wt% is obtained by using a silver nano-wire prepared through a salt assisted polyol technology as a conductive filler and PVP as a surfactant and a viscosity adjusting agent, adding an organic solvent and stirring for 30-35min. The silver nano-wire is purified through simply cleaning the prepared stabilized ink. The purified silver nano-wire can be used to produce high-performance transparent electrodes. The preparation method has the advantages of simplicity, easy implementation, good repeatability, high-concentration nano-wire storage benefiting and large scale production.
