This invention relates to the field of transfer paper coating technology, specifically to a thermal sublimation transfer paper coating and its preparation method. The invention first coats a photothermal dual-curing polyurethane emulsion onto a substrate paper, curing it to form a hydrophobic layer. The photothermal dual-curing polyurethane emulsion is composed of an epoxy-terminated silicone polyurethane modified with hydroxyl-terminated polydimethylsiloxane and capped with propylene glycol diglycidyl ester, and a double-bond capped polyurethane obtained by chain extension with glycerol monoglycidyl ether and capping with hydroxyethyl acrylate. Next, an ink-absorbing coating containing mercapto-modified silica, acrylamide monomer, and sodium carboxymethyl cellulose is coated onto the hydrophobic layer, cross-linking to form an ink-absorbing layer. Finally, a polyvinyl alcohol solution is coated onto the ink-absorbing layer to form a surface layer. The thermal sublimation transfer paper coating designed by this invention exhibits strong adhesion and excellent transfer effect.

The utility model discloses a same axis line coupling's device between shafting, same axis line coupling's technical field between shafting is related to, including outer lock ring, outer collar, cam piece, spring piece, inner collar and inner top ring, the inner hole is seted up in the inside of outer lock ring, the outside end arc top of cam piece is locked through the inner hole of outer lock ring, the inside of outer collar is seted up with square hole, and outer collar is positioned the position of inner top ring close to outer end arc top through square hole, this same axis line coupling's device between shafting, and the power source shafting on same axis is connected through the mounting hole of outer lock ring setting, and the passive shafting on same axis can be connected through the inner hole and key groove of inner top ring setting, and installation and maintenance are convenient, and the mounting hole of one end of outer lock ring has the mounting protective cover, can prevent the immersion of larger particulate matter, and also can make a little lubricating oil immerse lubrication, simple and convenient.

This utility model discloses a dual-sided battery swapping device, including two battery compartments, a platform, two movable door panels, a jetting mechanism, and two battery swapping trolleys. The two movable door panels are located below the battery swapping port. The jetting mechanism includes two air chambers, an air compressor, a distribution chamber, two air supply pipes, and two connecting pipes. The air chambers are mounted on the movable door panels and are located on the closed side of the two movable door panels. Multiple nozzles are mounted on the air chambers, with the nozzles spraying air vertically upwards. The output end of the air compressor is connected to the distribution chamber, which is connected to the connecting pipes via the air supply pipes. The connecting pipes are connected to the air chambers, and the air supply pipes are flexible. This utility model allows the air chambers to move with the movable door panels, effectively removing water droplets remaining on the vehicle chassis and preventing water from entering the battery swapping device, thus ensuring the safe use of the device.

The application relates to a liquid storage type siphon oil cooling device and belongs to the technical field of refrigeration equipment, which comprises a main liquid storage tank body, the side surface of the main liquid storage tank body is respectively provided with a liquid falling pipe and a plurality of system interfaces, the top of the main liquid storage tank body is respectively provided with a siphon cavity pipe and a gas return pipe, the top of the main liquid storage tank body is provided with the siphon cavity pipe, a special siphon cavity is integrated, the volume of the siphon cavity accounts for about 5% of the total volume of the whole container, through the layout of the cavity-on-cavity, function partition is realized, due to the space expansion and the change of flow velocity, the gas and liquid are sharply flashed and separated, in the siphon cavity, a large amount of gas generated by flashing carries lubricating oil, the lubricating oil is directly and efficiently transported back to the suction pipeline of the compressor through the gas return outlet at the top, the recovery of the lubricating oil is completed, the original function is realized, the overall installation space is reduced, and the floor space is smaller.

The application discloses a catheter material for varicose vein closure surgery and a preparation method thereof, and raw materials at least include 100-150 parts of a polymer base material, 10-15 parts of a lubricant and 3-8 parts of a coupling agent in terms of weight. The catheter material is corrosion resistant and has high compatibility with human bodies, can effectively prevent human body fluids and tissue fragments from adhering and immersing into the catheter material, thereby improving the use effect of the catheter material, can prevent the catheter from being touched with human tissues to cause damage, avoids damage to human tissues, can reduce discomfort and inflammatory reactions during use, and can meet the use requirements of clinical surgery.

The utility model discloses a handle in the technical field of handle without base, including handle, mounting seat, rotating seat and square shaft, the middle part of mounting seat is equipped with mounting hole, and handle installation place is equipped with fixed hole, and one end of rotating seat is connected in mounting hole through rotation, and the other end is hinged in fixed hole, and the middle part of rotating seat is equipped with the axle hole for installing square shaft, its characterized in that: the interval of rotating seat periphery is equipped with a plurality of positioning key groove, and the mounting seat is equipped with the positioning plate that is linked with positioning key groove, and the mounting seat is equipped with a plurality of positioning spring that is abutted with positioning plate. Handle sets up positioning plate and positioning spring in the mounting seat, and is through the cooperation of positioning plate and the multiple positioning key groove that rotating seat periphery interval sets up, realizes the rotary positioning of handle, and the structure of positioning plate and positioning key groove is more stable, and the assembly is more convenient and fast, and simultaneously simplifies the internal structure of handle, reduces the overall volume of handle, can be applicable to a variety of different size's space.
