This application discloses a power adapter cable outlet structure, relating to the field of power adapters. The adapter includes an adapter with a winding mechanism inside its cavity and a locking mechanism on one side. The winding mechanism includes a fixed rod fixedly installed inside the adapter, and a winding roller is provided on the outer surface of the fixed rod. This invention, through the action of the winding mechanism, can wind up the cable harness, facilitating the carrying of the adapter. Pulling the connector outward causes the cable harness to be released from the winding roller. After being pulled to the desired length, it is ready for use. During further pulling, the winding roller drives a circular plate to rotate outside the fixed rod, causing a torsion spring to twist. After use, because the torsion spring has been twisted and needs to return to its original position, the torsion spring drives the circular plate to rotate in the opposite direction, which in turn drives the winding roller to rotate, thereby winding up the cable harness. This design facilitates quick pulling out and winding of the cable harness.

The utility model provides a kind of food production sampling device, belong to food sampling equipment technical field, including the wall breaking head of sampling cylinder front end setting, sampling cylinder is provided with multiple first sampling port along its axial direction, sampling tube is rotatably provided in sampling cylinder, sampling tube is provided with multiple second sampling port along its axial direction, one stop sheet is arranged between two second sampling ports, stop sheet and sampling tube inner wall are slidably arranged, the end of sampling tube away from wall breaking head is provided with rotating part, the utility model separates by rotating torsion ring and makes external thread head and sampling tube, at this time, the rice material of lower depth can be taken out, and at the same time, the external thread head after disassembly is blocked at the second sampling port away from wall breaking head end, by pushing push rod, multiple stop sheets are synchronously moved, so as to push out the rice material of middle depth, finally, the rice material of upper depth is taken out, so that the food of upper, middle and lower layers can be accurately sampled and detected, so as to improve the accuracy of food sampling device sampling.

This utility model relates to the field of slag-sealing tank technology, specifically to a slag-sealing tank with a tank lid positioning device. When the mating tooth block and the locking tooth groove are engaged, there is a mating gap L on the same side of the mating tooth block and the locking tooth groove in the circumferential direction. The positioning device is located between the tank body and the tilting arm and is connected to the tilting arm. The positioning device includes two baffles parallel to the output direction of the vertical lifting mechanism. When the tank lid is closed, the bottoms of both baffles are in contact with the top of the tank body, and the opposite sides of the two baffles are located between the two sides of the same locking tooth groove. The distance H between the side of each baffle facing the other baffle and the side of the locking tooth groove in the same direction is less than L. In this utility model, the two baffles of the positioning device can restrict the movement of one mating tooth block on the tank lid in the circumferential direction when the tank lid rises and falls, thereby restricting the rotation of the tank lid and ensuring that the mating tooth block on the tank lid is correctly aligned with the locking tooth groove.

The utility model discloses a pin shaft node temporary support structure in space structure, it includes front support subassembly and rear support subassembly, and front support subassembly and rear support subassembly set up respectively in the front side and rear side of upper hinge base opposite lower hinge base rotation direction, and front support subassembly and rear support subassembly include first square steel pipe, second square steel pipe and jack, and first square steel pipe can be inserted in second square steel pipe and slide up and down, and the upper end of first square steel pipe is in abutment with the connecting top plate of upper hinge base, and the lower end of second square steel pipe is in abutment with the connecting bottom plate of lower hinge base, the side wall of first square steel pipe is welded with first supporting plate, and the side wall of second square steel pipe is welded with second supporting plate, and the jack is placed on second supporting plate, and the jacking end of jack is in abutment with first supporting plate, and first square steel pipe and second square steel pipe are fixed through bolt. Adopt the utility model, can solve the problem of the complex installation of temporary support structure in the prior art, inconvenient adjustment, insufficient stability.

This invention relates to a handle structure and an automotive window. The handle structure includes a safety component, a handle, and a locking component. The mounting component includes a corresponding mounting base and a handle stop. The handle includes a connected limiting section and a rotating section. The rotating section is rotatably mounted on the mounting base and has two mating parts spaced apart along the rotation direction. When the limiting section rotates with the rotating section, it has a window-locking position blocked by the handle stop and an window-opening position that avoids the handle stop. The locking component includes a locking member, which is movably mounted on the mounting base and corresponds to the mating parts, so that when the limiting section rotates to the window-locking position and the window-opening position, it can approach and move away from the adjacent mating parts. In this solution, the handle can be stably locked when the window is in the open or closed position, allowing the window to switch safely and quickly between the open and closed positions, effectively ensuring safety and providing simple and convenient operation.

This invention relates to the field of organic electroluminescent materials, specifically to an iridium metal complex, and more particularly to an iridium metal complex for deep red-near-infrared emission and its applications, as well as organic electroluminescent devices using the iridium metal complex of this invention. The iridium metal complex of this invention has the structure shown in formula (1). OLED devices prepared using the iridium metal complex of this invention exhibit higher luminous efficiency and better lifespan, demonstrating promising application prospects.

This utility model discloses a cable cutting device for electromechanical installation engineering, including a workbench. A base is provided at the bottom of the workbench, and a first support plate is provided on the upper surface of the workbench. A lifting cylinder is provided on the top of the first support plate, and a first limiting post is provided at the output end of the lifting cylinder. A transmission rod is provided on the side of the first limiting post, and a first cutting head is provided at the bottom of the transmission rod. Two support seats corresponding to the first cutting head are provided on the upper surface of the workbench. An arc-shaped groove is formed on the top of each support seat, and tensioning components are provided on both sides of each support seat. This application includes a first cutting head and a second cutting head.
