The utility model discloses a yarn placing rack which comprises a base, the top of the base is fixedly connected with a right side plate and a left side plate, a placing shaft is rotatably connected between the right side plate and the left side plate, a placing assembly is arranged on the placing shaft, a sliding groove is formed in the left side wall of the left side plate, a sliding block is slidably connected in the sliding groove, and a yarn placing assembly is arranged on the sliding block. A rack is fixedly connected to the left side wall of the sliding block, an inner electric rod is fixedly connected to the front side wall of the rack, and an outer box is fixedly connected to the left side wall of the left side plate. By arranging the placing shafts, the placing rods, the spacers, the outer sleeves, the outer limiting rings, the small electric rods, the stop rods, the inner limiting plates and the outer baffles, different types of yarns can be placed on the different placing rods, the yarns of the same type, different sizes and colors are placed on the same placing rod and are separated through the spacers, distinguishing and planning are easy, and the practicability is high. Excessive extrusion is avoided, and the extrusion force on the yarn is reduced.

The utility model relates to steel pipe bending technical field, concretely is a kind of bending device for steel pipe processing, including installation base, the upper end fixedly connected with mounting plate of installation base, opening is set up on the outer wall of mounting plate, the outer wall of mounting plate is fixedly installed with the abutting mechanism that can abut to steel pipe, the front end of mounting plate is also fixedly connected with electric telescopic arm by bolt, steel pipe hardness drops, it is explained that its quality exists problem, extrusion sensing mechanism can carry out the extrusion force of electric telescopic arm to leak force, the action of prompting that also played to avoid secondary injury of steel pipe, the steel pipe bending device innovative integration hardness detection and equipment protection function, the compression state of spring when steel pipe is under pressure Intuitive judgment hardness, spring keeps original state when hardness reaches standard, can be bent normally, linkage mechanism automatically triggers to deflate and unloads, reduces extrusion degree, avoids mould and equipment overload damage.

The utility model provides a sealed enhancement type flushes the valve control device, including the valve disc, be provided with the valve cavity in the valve disc, be provided with the valve plate in the valve cavity, fixedly be provided with and the control pivot of valve cavity rotation connection on the valve plate, open the flush mouth that is opposite control pivot eccentric on the valve plate, the disc surface of valve disc is equipped with the through -hole that flush mouth cooperation uses is connected with valve cavity, the annular limit slot that is located valve plate both sides is seted up in the valve cavity, the annular limit slot and the coaxial heart of through -hole, in the utility model, set up the positioning ring that can slide in the annular limit slot, then set up the supporting spring on one side of positioning ring, set up the sealing rubber bushing that is opposite and the valve plate on the other side, the supporting spring is extruded to sealing rubber bushing continuously by positioning ring, when sealing rubber bushing wears, the supporting spring still can make sealing rubber bushing to valve plate add certain extrusion pressure, has the advantage that strengthens the sealing.

The invention relates to the technical field of medical instruments, and discloses a flow limiting device of an infusion apparatus, which comprises a stroke rod, a thread is arranged at the position, close to the top, of the inner wall of the stroke rod, an adjusting bolt is mounted in a thread fit manner, and an extrusion spring is arranged at the top of the adjusting bolt. The bottom of the extrusion spring is in contact with the top of the extrusion cover, and the adjusting bolt rotates to be screwed under the action of thread fit, so that the extrusion spring is extruded to improve the pressure applied by the extrusion spring to the top of the extrusion cover. The adjusting bolt can be disassembled by reversely rotating the adjusting bolt, the extrusion cover can be lifted up and disassembled after the adjusting bolt is separated, and at the moment, the side hole can be removed from the outer side of the heating device, so that the separation of the side hole and the device is realized, and a flow limiting device in a traditional infusion device cannot be disassembled; and after being used, the device can only be discarded along with the side hole, so that waste is caused, the problem is well avoided, and the practicability of the device is improved.
