This utility model discloses a safe medical rail logistics anti-derailment structure, relating to the field of rail logistics anti-derailment technology. It includes a rail body and a rail logistics vehicle. Limiting mechanisms for preventing derailment are provided on both sides of the rail body, and a rotating mechanism is provided in the middle of the rail body. The limiting mechanisms include telescopic devices located on both sides of the rail body, with connecting rods fixedly connected to their surfaces. This utility model utilizes the driving force of the rail logistics vehicle to drive limiting balls to roll within a limiting sliding track. Limiting plates limit the connecting rods, preventing them from tilting under external force, thus enhancing the stability of the rail logistics vehicle. When the rail logistics vehicle's brakes fail, as it passes both ends of the rail body, the limiting balls are spring-loaded and engaged in limiting holes, effectively stopping the rail logistics vehicle.

This utility model relates to the field of general-purpose amplifier technology and discloses a long-life general-purpose amplifier, including a lower housing, an upper housing, an amplifier chip, and several pins. The pins are soldered onto the amplifier chip, and the amplifier chip is encapsulated between the lower housing and the upper housing by a potting compound. The top surface of the lower housing has several lower grooves corresponding to the pins, and a limiting post I is provided on the lower groove. The bottom surface of the upper housing has several upper grooves above the lower grooves, and a limiting post II is provided on the upper groove. A through-hole is formed between the lower groove and the upper groove, and the pin passes through the through-hole. A limiting hole is provided on the pin. This utility model effectively prevents the amplifier chip and pins from easily detaching, improves the overall structural stability, and thus extends the service life of the general-purpose amplifier.

This utility model discloses a plastic-coated steel pipe bend joint suitable for low-temperature conditions, comprising a bend section and straight pipe sections welded to both ends, forming a bend structure. It also includes: a stress buffer device comprising a corrugated compensator welded to the junction of the bend section and the straight pipe section, and a flow-damping orifice plate connected to the other end face of the corrugated compensator; and a damping sliding pair comprising a damping sliding tube fixed to the outer wall of the flow-damping orifice plate and a fixed damping kit fitted into the inner wall of the straight pipe section. The end face of the corrugated compensator connected to the flow-damping orifice plate is a free end that slides axially along the straight pipe section, and the damping sliding tube and the fixed damping kit achieve a sliding seal through an elastic seal. This utility model uses the sealing gas, the elastic material in the corrugated compensator, and the friction generated by the relative sliding of the damping sliding tube and the fixed damping kit to jointly counteract the pressure caused by frost heave, making the joint fully adaptable to low-temperature conditions.

The invention relates to a medical instrument, in particular to a clinical gastrointestinal decompression auxiliary device for the digestive system department. The invention provides a clinical gastrointestinal decompression auxiliary device for the digestive system department. A clinical gastrointestinal decompression auxiliary device for the digestive system department comprises a bed frame, a first bed board, a second bed board, a first side edge board, a first connecting rod, a movable rolling wheel piece and the like. Second bed plates are hinged to the two sides of the first bed plate. A first side plate is fixedly connected to one side of the bed frame. Second connecting rods are longitudinally and symmetrically connected to the first side plate in a sliding mode. First connecting rods are transversely and fixedly connected to the bottoms of the second connecting rods, and movable rolling wheel pieces are arranged on the tops of the two second connecting rods. The winding drum cloth is matched with the clamping assembly, the drawn winding drum cloth directly covers the upper body of a patient, and the winding drum cloth laying process has the effects of being simpler, more comprehensive and more stable.

The utility model discloses an industrial robot base adjusting device and relates to the technical field of industrial robot bases, the industrial robot base adjusting device comprises a chassis and a base, the inner wall of the chassis is provided with a built-in groove, the outer wall of the top of the chassis is contacted with the outer wall of the bottom of the base, and a placing table is fixedly connected to the middle axis of the inner wall of the base. By arranging the placing table on the base, when the industrial robot equipment needs to be used, the industrial robot equipment is placed on the top surface of the placing table, then a motor is started, when the motor is started, a rotating shaft is driven to enable a fluted disc to start to move, and then the fluted disc drives a fluted disc II to rotate on the outer surface of a fixed rod; and when the second fluted disc rotates, the connecting disc can be driven to move together, and when the connecting disc moves, the multiple teeth can be driven to rotate together, so that the industrial robot base can be quickly adapted to the size of the industrial robot base to be quickly fixed, and the condition of inclination during use is prevented.
