A mold, fixture, and forming and testing method for uniaxial tensile testing of concrete are disclosed. The mold includes a base plate, side plates, and a non-standard assembly block formed by bolting a flat plate and a transition block with an arc. After assembly, the whole block has a gradually changing cross-sectional shape adapted to a dog-bone rod-shaped specimen, which can ensure that the transition section of the specimen is formed regularly and the dimensional accuracy is consistent, effectively avoiding the stress concentration problem caused by unreasonable transition section design in traditional molds. The fixture is clamped at the upper and lower ends of the specimen, and the fixture has a V-shaped groove that matches the end of the specimen. At the same time, a fixing steel plate is added to limit the deformation of the fixture. The V-shaped groove fits tightly with the side wall of the specimen, which can effectively limit the lateral movement of the specimen during the tensile process. When testing the dog-bone rod-shaped concrete specimen, the deformation of the tensile area is measured by an extensometer and its rectangular frame fixing device, and the full stress-strain curve of concrete under uniaxial tension can be obtained.

The utility model relates to a plastic packaging box technical field especially relates to a special-shaped plastic packaging blister box. The special-shaped plastic packaging blister box includes blister box body, protection shell, flexible band, drive assembly and sponge pad, and the inside of blister box body is provided with the placement groove equidistantly, and the outside of blister box body is provided with the protection shell, and the inside placement groove of blister box body is all installed with the flexible band symmetrically, and drive assembly is installed between blister box body and flexible band. The special-shaped plastic packaging blister box provided by the utility model realizes the quick taking out of battery through the linkage design of drive assembly and flexible band, and the operator only needs to push the push plate to make the flexible band protrude upwards, and the precision battery in the placement groove is lifted, and it is not necessary to pinch or pry with fingers. This structure completely avoids the problems of battery shell scratch, falling and the like caused by improper force.

This invention provides a high-precision auxiliary positioning device for gift box lamination production, belonging to the field of gift box production technology. It solves the problem of cumbersome operation in existing paper box production processes where, when the width of the paper box changes, not only are the front and rear baffles individually adjusted inwards or outwards, but also excess rollers need to be added or removed according to the paper box width. The entire adjustment process is cumbersome. The device includes a laminating machine body, a first operating handwheel, support frames, guide adjustment components, and spacing adjustment components. The first operating handwheel is rotatably connected to the right side of the transmission box. The three support frames are dispersedly and fixedly connected to a fixed plate. Two sets of guide adjustment components are respectively located behind two transmission worm gears. The three sets of spacing adjustment components are respectively located inside the three support frames. This invention can drive the baffles on both sides to move synchronously inwards or outwards, and the spacing of multiple pressing rollers can be adjusted synchronously along the guide rod, achieving rapid auxiliary positioning of paper boxes of different widths and making operation faster.

The utility model discloses a kind of flower seedling fixing devices, it is related to the technical field of flower seedling cultivation, including support structure, anti-toppling structure, righting structure and adjusting structure, support structure includes baffle ring, connecting rod and support component, two baffle rings are horizontally symmetrical and are arranged, connecting rod is fixedly installed between two baffle rings, several support components are fixed in baffle ring outer periphery, support component is evenly arranged in baffle ring outer periphery.The flower seedling fixing device support structure design has two kinds of fixed mode, can be applied respectively in small-sized container cultivation such as flowerpot and the place of large quantity cultivation such as field, the anti-toppling structure set can be realized to the anti-toppling protection of flower seedling by the fixing of the lower side of flower seedling stem, cooperate the fixing of guiding component in righting structure to another position of flower seedling stem, flower seedling can also effectively improve the anti-lodging effect of flower seedling, and maintain the upright growth of flower seedling, so as to effectively improve the practicality and use effect of device.
