The invention provides a composite fabric with built-in medicine powder, its production method and application. The composite fabric includes a water-repellent and antibacterial outer layer, a nanofiltration layer, an antibacterial fabric layer and a unidirectional moisture-conducting layer that are sequentially stacked, and the antibacterial fabric layer is a woven fabric layer containing a built-in drug powder yarn. With such a setting, on the one hand, the nano-filtration layer is used to block the invasion of nano-scale viruses from the outside; on the other hand, the moisture vapor of the virus on the population side is guided into the woven fabric layer to kill the virus through the one-way moisture-conducting layer. The invention adopts strip-type orderly stacking to produce composite fabrics, creatively integrates the integrated processing of non-woven, woven and knitted fabrics, and synergistically exerts the properties and functions of each fabric. The composite fabric prepared by the invention has good bactericidal, antibacterial, anti-virus functions and good sterilization persistence, and can prevent the virus on the composite fabric from returning to the air, solve the problem of secondary damage, and can be used for haze prevention, sterilization, Composite fabrics such as antibacterial or antivirus materials.

The invention discLoses an automobiLe knee airbag device. The device comprises a U-shaped sheLL body formed by sequentiaLLy connecting an instrument paneL sheLL, a steering wheeL fixing sheLL and an airbag fixing pLate, wherein the airbag fixing pLate is fixedLy provided with an airbag sheLL, a partition pLate is fixed in the airbag sheLL, the partition pLate divides the inner portion of the airbag sheLL into a first cavity and a second cavity, the first cavity is internaLLy provided with a curLed first airbag, and the second cavity is internaLLy provided with a second airbag. The automobiLe knee airbag device soLves the probLems that a conventionaL knee airbag device effectiveLy and comprehensiveLy protects the Legs of a passenger difficuLtLy, especiaLLy different passengers have different sitting postures, the Legs may in bent states or verticaLLy straight state, a singLe airbag cannot protect the Legs effectiveLy, in addition, when a conventionaL airbag is ejected, the mounting sheLL body of a fixed airbag may faLL off to cause secondary injury to the Legs of the passenger.

The invention discloses an anti-fall self-locking device for a vertical hoisting elevator. The device is mounted on a car bottom frame of the elevator, and comprises a rack rod and a straight gear shaft; the rack rod is provided with a rack and a strip-shaped plate; the rack rod is vertically mounted on a building wall of an elevator shaft; the straight gear shaft is provided with a straight gear and a hexagonal block; three blind holes are radially formed in three spaced surfaces of the hexagonal block; a bulb cylinder rod is inserted in each blind hole; and cylindrical spiral stretching springs are arranged at one ends, facing to the axes, of the bulb cylinder rods. When an elevator traction rope is ruptured, the falling speed is higher than the normal operating speed; when the elevator falls to the rack rod position, the straight gear is engaged with the rack, and the straight gear and the hexagonal block also rotate at high speed; the centrifugal force of the bulb cylinder rods overcome the tension of the cylindrical spiral stretching springs to enable the bulb cylinder rods to radially extend outwards; and the extending bulb cylinder rods form self-locking included angles with the strip-shaped plate, so that the elevator is clamped in a self-locking manner to stop falling.

The invention discloses a medical freed body moving platform which comprises a chassis assembly, wherein the chassis assembly is vertically provided with a stand column; the exterior of the stand column is movably connected with a stand column sleeve to carry out the heaving movement; the stand column sleeve is fixedly connected with a bracket; the chassis assembly comprises a chassis, a supporting leg and a gear driven by a motor; the supporting leg supports the chassis and is connected with the bottom of the chassis in a sliding way; a rack is arranged between the gear and the supporting let; the gear drives the rack to move; the supporting leg is fixedly connected with the rack; the bottom of the supporting leg is provided with a pulley wheel which is contacted with the ground; and themotor drives the supporting leg to slide by the gear, the rack and the pulley wheel. The medical freed body moving platform can stably hold up and move the bodies of patients, is slowly inserted intothe underside of the human body after the panel is moved and regulated to the appropriate position, slowly holds up and move the body, is convenient to operate, effectively reduces the labor intensity of the medical personnel, has low cost, can be matched with all operational connecting stretchers and operational cars for using, and well solves the secondary harm problem caused by the movement ofthe patient body.

The invention relates to a deviation rectification method for local settlement of a pile foundation building. The method comprises the following step: according to the settlement inclination conditionof the building, a jack bearing platform is additionally arranged on a pile with large settlement capacity to serve as a loading platform, a building serves as a counter-force point, a jack is adopted for gradually loading in a graded mode, a pile end is made to be located on a bearing layer by pressing the pile with the self-weight of the building, the later use bearing capacity is met, meanwhile, the jack bearing platform serves as the counter-force point, the building settled due to collapsing is lifted, and the purpose of deviation rectification is achieved. The application of the invention enables the settlement volume and the inclination correction rate to be effectively and safely controlled, the bearing capacity of the pile meets the requirement of safe use after back pressure isfinished, the problems that the settlement amount and the inclination correcting speed are not easy to control, and secondary uneven settlement or re-inclination is easily caused are well solved, andmeanwhile, the problem that secondary damage is caused to an upper structure in the jacking process is also solved. The construction process is simple and convenient, particularly conforms to the force transmission principle, is safe and reliable, and is worthy of wide-range popularization and application.

The invention discloses a positioning tool for an automobile mold. The positioning tool comprises a base, a fixed seat, a connecting seat and a sliding seat; the lower end of the fixed seat is fixedlywelded to the seat, a clamping piece and an adsorption fixed piece are slidably installed in the fixed seat, two pressing pieces are installed at the upper end of the fixed seat; the connecting seatis fixedly welded on one side of the fixed seat, and two sides of the connecting seat are rotationally provided with hydraulic pushers respectively; and the sliding seat is connected with the connecting seat through the hydraulic pushers, and the lower end of the sliding seat is slidably arranged on the seat. The positioning tool has the advantages that operation is simple and convenient, mold parts with irregular shapes such as an automobile top cover and an instrument panel in the automobile mold can be fixed in an all-dimensional mode, so that operation of machining, maintaining and the like of the automobile mold is very convenient; and meanwhile, design is reasonable, so that the problem of secondary damage of the automobile mold caused by rigidity fixing is effectively solved, and the phenomena of damage or paint falling of the automobile mold caused by collision in the machining and maintenance processes are avoided, processing efficiency and processing convenience are improved,and good use and popularization values are achieved.
