This invention relates to the field of safety protection technology for industrial lifting slings used in factory lifting and logistics transportation. Existing industrial lifting slings are frequently cut or severed by components, posing significant safety hazards and wasting resources. This invention is simple, convenient, and low-cost to manufacture, allowing for mass production and widespread marketability. The invention involves embedding appropriately sized strong magnets into a 90-degree angle steel of a suitable length. During use, the magnets adhere to the component, protecting the lifting sling and greatly ensuring safety while reducing wear and tear. This invention can be used in manufacturing industries and truck transportation industries that consume large quantities of lifting slings.

The present disclosure provides a safe conductive coating slurry, a composite current collector and a preparation method thereof, and a battery, and belongs to the field of battery materials. The safe conductive coating slurry for the composite current collector comprises, in terms of mass fraction, 15-30 parts of a main material, the main material comprising microcrystalline glass; 10-30 parts of a binder; 10-20 parts of a solvent; 0.5-2 parts of a dispersing agent; 0.5-1 part of a wetting agent; and 0.5-1 part of a leveling agent. The coating slurry of the present disclosure comprises microcrystalline glass, which can simultaneously play the roles of a conductive coating and a safe coating by only coating one layer of coating, thereby simplifying the preparation process and the coating process; when combined with an electrode active material, the coating slurry does not cause the electrode active material to fall off; and the safe conductive coating has no cracking phenomenon. The technical problems of the prior art, such as the complexity of the slurry preparation process and the coating process when the two-layer structure of the conductive coating and the safe coating is coated on the composite current collector, the easy falling off of the electrode active material when combined with the electrode active material, and the easy cracking of the conductive coating, are avoided.

This utility model relates to the field of sprayers, specifically a nozzle assembly and a sprayer cap, including a connector and a nozzle seat coaxially rotatably fitted with the connector. The connector has an axially oriented outlet channel communicating with a liquid source. A sealing ring is provided outside the outlet channel, with at least one section of the sealing ring extending outwards away from the outlet channel. The nozzle seat presses against the sealing ring and encloses the extended section of the sealing ring to form an outlet cavity communicating with the outlet channel. The nozzle seat has at least two different nozzles arranged in a circumferential array around the axis of the nozzle seat. The nozzle seat has outlets corresponding to the positions of each nozzle. When each outlet rotates to correspond to the position of the outlet cavity, the outlet channel supplies liquid to at most one set of nozzles through the outlet cavity and the outlet. This utility model enables rapid adjustment of the spray range of the sprayer.

The present application provides a kind of children safety seat with angle adjusting function and rotating function, it is related to children safety seat technical field, comprising: reversing component, the reversing component is composed of switching mechanism and transmission mechanism, seat component can realize the function of quick, automatic adaptation of boarding and alighting posture, only need to pull operating lever, connecting base plate can automatically drive seat component to rotate ninety degrees, and by reversing component can adjust the rotating direction of connecting base plate, so that seat component is automatically oriented to the side of door, it is convenient for the holding or placing of children, greatly simplify the operation process, reduce the length of time of temporary parking of vehicle, solve the problem that the existing children safety seat cannot automatically adapt the use posture of boarding and alighting, the placing and holding steps of children when boarding and alighting are complicated, not only consume time, also will extend the length of time of temporary parking of vehicle, to a certain extent, improve the on-site safety hazard.

The application relates to the field of positioning equipment and discloses an indoor precise positioning equipment, which comprises an equipment body, a groove one is formed above the right side surface of the equipment body, a signal antenna is rotationally arranged in the groove one, a display screen is arranged on the equipment body, and a turnover protection structure is arranged on the equipment body and used for arranging the display screen. Through the turnover protection structure and a rotating positioning structure, when the equipment is carried, the rotating positioning structure is used to drive the turnover protection structure to turn over on the side surface of the equipment body, so that the display screen is turned over and stored in a storage groove. The turnover protection structure not only plays a safe protection role and reduces the scratch problem, but also plays a dustproof role. After being turned over, the turnover protection structure and the display screen are positioned as a whole. When the turnover protection structure is accidentally hit, a plurality of spring sheets on the turnover protection structure can play a shock absorption and protection role, and the damage problem of the display screen is reduced.
