The utility model provides a kind of torpedo tank truck automatic uncovering device, belong to torpedo tank truck heat preservation technical field, comprising: lifting hydraulic cylinder, support seat, installation shell, electro-hydraulic push rod, tank cover structure, guide assembly and compression assembly;Lifting hydraulic cylinder and support seat are all arranged in the side of torpedo tank truck, and the telescopic end of lifting hydraulic cylinder and the top of support seat are respectively connected with installation shell rotation;Electro-hydraulic push rod is equipped in installation shell, and electro-hydraulic push rod is connected with tank cover structure;Guide assembly is set in installation shell, guide assembly is located at the two sides of electro-hydraulic push rod, and is attached with the bottom surface of tank cover structure;The device is used in combination by lifting hydraulic cylinder, support seat and electro-hydraulic push rod, realizes tank cover translation type to uncovering cover operation, need not vertical overturning space to be able to be stably operated in workshop, and tank cover structure is guided and limited by guide assembly and compression assembly, to avoid the risk of tipping caused by gravity center deviation, to ensure the stability of device.

This utility model discloses a protective cover for an intelligent controller, including an intelligent controller body. The surface of the intelligent controller body is provided with a button control area, a display area, and a protective cover covering the upper surface of the button control area. One end of the protective cover is a hinged end, and the upper and lower ends of the hinged end are respectively provided with a first connecting post and a second connecting post. The intelligent controller body is respectively provided with a first slot and a second slot that cooperate with the first connecting post. The depth of the first slot is greater than that of the second slot. When the protective cover moves upward, the second connecting post can be pulled out of the second slot; when the protective cover moves downward, the first connecting post cannot be pulled out of the first slot. This application ensures the safety of the protective cover during use through a unique slot design. The difference in depth between the first and second slots effectively prevents the protective cover from being accidentally removed and falling off in case of accidents, improving product reliability and user experience.

This utility model belongs to the field of electric bed technology, specifically an internal roller guide structure and an electric bed with abdominal relief function. The internal roller guide structure includes a fixed tube, a movable tube, and rollers. One end of the movable tube is inserted into the fixed tube. The rollers are located inside the fixed tube, and two pairs of rollers are spaced apart on the movable tube to support the extension and retraction of the movable tube within the fixed tube. This utility model's internal roller guide structure is simple in structure and flexible in operation. When applied to an electric bed, the extension of the movable tube allows the backrest board to shift backward, releasing the pressure exerted by the mattress on the body and improving comfort.

The present application relates to the technical field of safety seats, in particular to a child safety seat, which comprises a base and a body assembly, the body assembly comprising a body seat and a body frame, the body seat being fixed in the inner cavity of the body frame; by setting a trigger mechanism, the operation steps are greatly simplified, the convenience and the adjustment efficiency are significantly improved, by setting a gear adjusting mechanism and a seat rotating mechanism, automatic locking is realized, the smoothness and the positioning accuracy of gear switching are ensured, the rotating locking is more stable and reliable, the problems of jamming or loosening after long-term use are effectively avoided, by setting a body dismounting mechanism, the defects of easy loosening and difficult dismounting of traditional bolts or complex buckles are avoided, the cleaning, replacement or carrying of the seat body by the user are greatly facilitated, by setting a rotating bolt and a front reinforcing iron of the base, the safety hazards caused by incomplete locking are avoided, and the convenience and the safety are further improved.
