The utility model relates to a kind of assembled membrane structure refrigeration ground, and it relates to the technical field of ice rink.The present application provides a kind of assembled membrane structure refrigeration ground, including ground layer, heat preservation layer, water storage layer, snow making layer from bottom to top sequentially arranged;The water storage layer includes water storage tank, refrigerant pipeline, and the refrigerant pipeline is laid in the bottom of water storage tank.The utility model uses air film to make the waterproof, water-bearing disc of water storage layer, ice surface layer can be directly formed in the disc-shaped space of air film production, simple construction, low cost.

This utility model relates to the field of transformer testing technology, specifically disclosing a transformer insulating oil sampling device, including a shell. The shell is a hollow cuboid structure, and an outer cylinder is fixedly connected to the inner wall of the shell via a connecting rod. The outer cylinder is a hollow cylindrical structure, and an oil inlet pipe, a sampling pipe, an oil outlet pipe, and a sampling tube are respectively installed through the outer surface of the outer cylinder. This transformer insulating oil sampling device features a rotatably connected outer cylinder and inner cylinder. The inner cylinder has a three-way flow channel, and the flow channel between the pipes can be adjusted by rotating the inner cylinder. This allows the pipes inside the device to be flushed before sampling, removing residual air impurities and other substances that interfere with the experiment, improving the accuracy of insulating oil sampling, and making subsequent test data more accurate and reliable.

The utility model belongs to the technical field of enema tool, concretely is a kind of paediatrics enema device, including syringe, the one end outside of syringe is sleeved with injection hose, the outside of injection hose is sleeved with positioning assembly, the positioning assembly includes positioning sleeve, the outside of injection hose is sleeved in positioning sleeve, the one end inner wall of positioning sleeve is fixed with second extrusion washer, the other end inner wall of positioning sleeve is fixed with third extrusion washer.The utility model will positioning sleeve be sleeved in the outside of injection hose, when inserting injection hose, positioning sleeve is inserted into the inboard of the anus of sick child to carry out plugging positioning, so that injection hose can stably keep insertion depth, after enema for small child, operator extracts injection hose, positioning sleeve still stays at the anus of small child at this time, medical staff can insert plug into the inboard of positioning sleeve to carry out plugging, effectively block enema liquid to flow out, without parent pinch small child hip, improve the convenience of enema operation.

The application belongs to the technical field of cleaning equipment, and particularly relates to a side-leakage-preventing integrated nozzle and a scrubber, which comprises a water spraying seat, a plurality of water outlets are uniformly arranged on the inner cavity bottom surface of the water spraying seat, an elastic pipe is arranged in the water outlet, guide rods are fixedly connected to the two sides of the cavities, a counterweight seat is arranged in the cavity, slide sleeves are fixedly connected to the two sides of the counterweight seat, push shovels are arranged on the two surfaces of the counterweight seat close to the connecting grooves, when the water spraying seat is inclined, the counterweight seat drives the slide sleeve to slide along the guide rod to the lower end of the water spraying seat under the action of gravity, the push shovel at the lower end of the counterweight seat slides into the connecting groove, the push shovel pushes the middle part of the elastic pipe, the middle part of the elastic pipe is bent and compressed, the two outer walls of the elastic pipe are extruded and attached, the elastic pipe is blocked, the residual water in the flow channel is prevented from flowing out of the lower water outlet, and the dryness of the ground around the scrubber is improved.

The utility model relates to the technical field of cross shafts, and discloses a sealing cross shaft universal joint for a passenger car, which comprises a cross shaft body, a shaft neck, a shaft sleeve and a roller pin rotationally arranged between the shaft sleeve and the shaft neck, two symmetrically arranged protective half shells are sleeved outside the cross shaft body, a fixing hole is formed in the diagonal position of any protective half shell, and the shaft neck is sleeved outside the shaft sleeve. Fixing holes are formed in the shaft neck, fixing rods used in cooperation with the fixing holes are arranged at the other two opposite angle positions of each protection half shell, a through oil injection opening is formed in any protection half shell and used for injecting grease into an inner cavity of the corresponding protection half shell, a first oil seal is further arranged on the shaft neck and is an external C-shaped oil seal, and a second oil seal is arranged on the shaft neck and is used for sealing the outer C-shaped oil seal. The second oil seal is arranged at the position of an inner port of the shaft sleeve and is a built-in star-shaped oil seal, the first oil seal and the second oil seal are used for preventing impurities from entering and lubricating oil from flowing out, and the problems that existing equipment is prone to being damaged by the impurities in the external environment, and lubricating oil is prone to leaking are solved.
