The utility model belongs to the technical field of wine jar, specifically relates to a integrally formed glass wine jar, it includes jar body, characterized by: the lower part of jar body is equipped with the valve seat of integrally forming with jar body, is equipped with the valve cavity in the valve seat, the upper end of valve cavity is the mounting port, the lower end is communicated valve nozzle, the inner diameter of valve nozzle is less than valve cavity, and valve cavity is linked together with jar body, still include valve cover and elastomer, valve cover can be assembled on the mounting port, the top wall of valve cover is equipped with through -hole, is equipped with valve rod in through -hole, the lower part of valve rod is located in valve cavity, the lower part of valve rod has valve head, valve head can block valve nozzle, the lower end of elastomer is connected valve rod, and the upper end is connected valve cover, the jar only needs to install valve cover and valve rod on the valve seat, reduces the connection between valve seat and jar body and the sealing of junction, not only has simplified the connecting structure between discharge valve and jar body, still makes the connection between discharge valve and jar body and the service life of jar body, avoids the connecting part of both to leak due to the sealing problem.

This invention relates to the field of pole-mounted circuit breaker technology, and more particularly to a primary and secondary integrated pole-mounted circuit breaker that is easy to install. It includes a circuit breaker body, with two mounting brackets fixedly installed below the circuit breaker body. A lifting base is located on one side of the circuit breaker body, and a top mount and a base are respectively located on the upper and lower sides of the lifting base. The lifting base, top mount, and base are all composed of two arc-shaped frames connected by bolts. By setting up the lifting assembly and lifting base, and by cooperating with the fixed pulley on the top mount and the movable pulley on the lifting base, the force-saving pulley system formed by the fixed pulley and movable pulley significantly reduces the lifting force when winding the steel cable. In mountainous areas and narrow road sections where cranes cannot access, the circuit breaker can be lifted and installed by ground personnel alone, improving the equipment's adaptability to complex installation environments. A single person can complete the lifting of the equipment, significantly reducing the labor intensity of manual handling and high-altitude lifting, shortening installation time, and improving construction efficiency.

The application discloses a product detection equipment, and particularly relates to the technical field of product detection, which comprises a detection rack, a workpiece and a suction device, the inside of the detection rack is sequentially provided with a work station clamping block, a multi-motion transfer frame and a positioning plate, the work station clamping block and the multi-motion transfer frame are used for stably placing the workpiece inside the positioning plate, the inside of the positioning plate is provided with a clamping assembly, and the clamping assembly is used for applying constant pressure to the workpiece inside the positioning plate and lifting the workpiece to observe the sample surface change during the detection process; after the positioning plate carries the workpiece and moves to a preset detection position, the clamping claw opens in an eight-shaped arc line movement along the bottom of the workpiece, the claw body retracts along an arc line track, still slides along the arc surface of the bottom of the workpiece in the initial stage of separation, gently weakens the lifting force, avoids instantaneous separation of the two, the top convex frame pushes the workpiece upward, the bottom of the workpiece is lifted away from the position of the claw tip, and the workpiece presents a low-obstruction suspended support state in the detection station.
