The utility model provides a novel automobile refueling charging port box structure, including the port box, be equipped with cavity, at least one axle hole and a fixed structure on the port box, executor, the executor can be detachably fixed on the fixed structure of port box, and can realize electric control positive and negative rotation, pivot, pivot with executor drive connection, hinge, the hinge passes through pivot with port box movable connection to rotate around the axle hole of port box, the rotating portion inside of hinge is equipped with a plastic metal insert, and outer plate, the outer plate is fixed on the hinge, and with the synchronous movement of hinge. The utility model can solve the problem that the pure plastic hinge of prior art is prone to deformation and fracture due to long-term stress, significantly prolongs the service life of the port box mechanism.

The utility model relates to the technical field of the tight sleeve, and disclose a heavy load machinery anti -deformation tight sleeve, including tight sleeve body, the outer surface of one end of tight sleeve body is equipped with thread groove, the one end of tight sleeve body is equipped with a plurality of connecting grooves, the circumferential surface of tight sleeve body is equipped with a plurality of installation grooves, the inside of installation groove all are fixedly installed with the reinforcing rib, the inside of tight sleeve body is installed with wear -resisting subassembly, and the connecting end of wear -resisting subassembly is connected with connecting groove thread connection. The utility model discloses through the setting of wear -resisting subassembly, when tight sleeve body uses, and the reinforcing sleeve can avoid tight sleeve body deformation, simultaneously, when mechanical operation, the high friction layer of reinforcing sleeve inner surface can effectively increase the friction between the cooperation component, and the high friction layer of ceramic particle coating material quality safeguards the stability of tight sleeve under long -term heavy load, high speed and other complex working conditions with its good friction performance, improves the deformation resistance, and increases the connection stability.

This invention belongs to the technical field of motor bases, specifically relating to an automatic leveling motor base suitable for low-temperature environments. It includes a fixed cylinder, a support frame fixedly connected to the top of the fixed cylinder, a motor frame fixedly connected to the top of the support frame, leveling cylinders fixedly installed at the four corners of the bottom of the support frame, a protective frame fixedly sleeved around the support frame, and limiting frames symmetrically fixedly installed on the front and rear inner walls of the protective frame. Movable frames are located directly below the corresponding limiting frames. A heating cavity is provided inside the side wall of the protective frame. Conductive rods are fixedly connected to the side walls of the leveling cylinders, and resistance blocks are fixedly installed on the side walls of each connecting plate. One end of each conductive rod is slidably connected to the side wall of the corresponding resistance block. This motor base utilizes the heating cavity for auxiliary heating, avoiding insufficient lubrication and electronic component failure. When irreversible damage occurs at the connection between the base and the ground, the fixed cylinder provides a temporary stable working condition. Automatic leveling is achieved through the leveling cylinders, conductive rods, and resistance blocks.

The utility model relates to a hydraulic cylinder with integrated piston rod, including cylinder body, cylinder cover and integrated piston rod. Among them, the cylinder body is hollow structure, and the length direction one end is closed, and the other end is open. The one end of cylinder body is provided with cylinder cover. The cylinder cover is provided with the piston rod hole that integrated piston rod passes. Integrated piston rod includes the ear ring part of stem and. The one end of stem is provided with the piston and passes into the cylinder body through the piston rod hole, and can slip along the own axial direction in the cylinder body, and the other end forms integrated structure with ear ring part. The ear ring part is annular, is used for connecting integrated piston rod other equipment. The piston divides the cylinder body inside into the rod cavity and the rod cavity. The cylinder body is provided with hydraulic passage and exhaust passage. The utility model discloses through adopt integrated piston, makes the stem and ear ring part between will not loosen or fail because of long -time use, has improved the reliability of hydraulic cylinder whole.
