The utility model relates to the technical field of computer communication, and discloses a distribution frame for a computer communication network, which comprises a distribution frame body, the left end and the right end of the front surface of the distribution frame body are correspondingly provided with two mounting holes, and the front surface of the distribution frame body is sequentially provided with a plurality of communication interfaces. Two fixing blocks are correspondingly welded to the lower end of the front surface of the distribution frame body, the protection mechanism is arranged on the front surface of the distribution frame body, the protection mechanism is used for protecting a protection sleeve of a network cable, the protection mechanism comprises a protection plate, and the protection plate is arranged on the front surface of the distribution frame body. According to the network cable protection device, the network cable exposed to the outside at the interface can be protected, the bending amplitude of the network cable at the interface is reduced, the network cable can be further protected, the service life of the network cable is prolonged, the safety of the device is improved, the network cable can be branched, the network cable can be classified clearly, and the difficulty during maintenance is reduced.

The utility model relates to the technical field of flexible magnets, in particular to a flexible magnet which comprises a flexible magnetic plate body, a hollow area is arranged in the flexible magnetic plate body, a plurality of elastic supporting columns are obliquely fixed in the hollow area, and a plurality of magnetic protruding blocks are fixed to the upper side and the lower side of the flexible magnetic plate body. Shallow grooves are formed in the upper sides of the magnetic protruding blocks, high-abrasion-resistance rubber sheets are fixed in the shallow grooves in an adhesive mode, and connecting structures are fixed to the periphery of the flexible magnetic plate body. The flexible magnet solves the problems that an existing flexible magnet is low in fatigue resistance, cracks are prone to occurring, abrasion resistance is low, and the surface of the existing flexible magnet is prone to being damaged.

The invention discloses an intrauterine device fixing device and belongs to the field of medical instruments, the intrauterine device fixing device comprises a transverse rod and a longitudinal rod, the transverse rod is transversely arranged at the top end of the longitudinal rod, the transverse rod and the longitudinal rod form a traditional T-shaped ring structure, and the technology is an existing mature technology and is not repeated; an adjusting mechanism is arranged in the longitudinal rod in a sliding mode, a protective sleeve is arranged at the intersection of the transverse rod and the longitudinal rod in a sleeving mode, and an installation auxiliary mechanism is arranged at the bottom of the longitudinal rod when the ring feeding operation is conducted. The defect that the contraceptive ring in the current market is poor in stability is effectively overcome.

The invention relates to the field of ship guide ropes, and particularly discloses a ship guide rope structure. By arranging the rotating return assemblies, the telescopic cylinders, the mounting blocks, the rotating shafts, the hinge rods, the telescopic sliding rods and the external expansion plates, a guide rope penetrates through the center of an annular hole formed by the mounting blocks, and during action, no matter the guide rope turns towards any direction, the guide rope can be attached to the rotating shafts of the mounting blocks corresponding to one or more sets of telescopic cylinders, so that the guide rope is more stable. Sliding friction force borne by the guide rope is converted into rolling friction force through the rotating shaft, friction damage to the guide rope in the long-time using process is effectively reduced, when stress of the guide rope is increased or the direction change is large, the guide rope downwards presses the telescopic cylinder through the rotating shaft and the mounting block, and the telescopic cylinder retracts to drive the hinge rod to rotate; the rotating hinge rod outwards pushes the telescopic sliding rod, the telescopic sliding rod outwards pushes the external expansion plate, at the moment, the distance between the external expansion plate and the rotating shaft is increased, the turning angle of the guide rope is increased, and then abrasion to the guide rope during steering is effectively reduced.

The invention relates to the technical field of coatings, and discloses an environment-friendly coating for a green building exterior wall and a preparation method thereof.The preparation method comprises the steps that toluene-2, 4-diisocyanate and hydroxypropionyl phthalimide alkyl amide are reacted, then reacted with epoxy resin and neutralized; and finally, adding water, an emulsifier, a defoaming agent, a dispersing agent and pigments and fillers to obtain the environment-friendly coating for the green building external wall. The water-based paint is clear, transparent, free of layering, good in dispersity and excellent in storage stability. And the flexible alkyl long chain is grafted into the epoxy resin, so that a good toughening effect can be achieved, and the bending strength and impact strength of an epoxy resin casting body can be improved. The high-temperature-resistant phenyl imide ring group is grafted into an epoxy resin molecular chain, the initial thermal decomposition temperature of the epoxy resin can be increased, and the high-temperature-resistant phenyl imide ring group has wide application prospects in the fields of high-performance heat-resistant anti-ultraviolet weather-resistant coatings, building outer walls and the like.
