The invention discloses a dust prevention type screw with a shielding piece. The dust prevention type screw comprises a screw head and a threaded rod, a cross-shaped groove is formed in the upper endface of the screw head, two first grooves symmetrical front and back and two second grooves symmetrical left and right are formed in the cross-shaped groove, first holes are formed in the inner side groove walls of the first grooves, second holes are formed in the inner side groove walls of the second grooves, hole openings of the first holes and the second holes are all arranged in a manner of facing the center of the cross-shaped groove and are vertical to the central axis of the threaded rod, and the first holes and the second holes are provided with first stretchable plates and second stretchable plates correspondingly. The dust prevention type screw with the shielding piece is simple in structure, convenient to install and manufacture, easy and quick to operate, capable of effectivelyshielding a cross-shaped opening of the head of the screw, free of influences on installing and detaching, capable of effectively preventing foreign matters from entering the opening, and high in practicability.
Description
Technical field: [0001] The invention relates to a dust-proof screw with a cover and relates to the technical field of screw fasteners. Background technique: [0002] Fasteners, also known as standard parts in the market, are a general term for a class of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical basic parts and are in great demand. At present, many screw heads are equipped with a cross opening for the head of a Phillips screwdriver to fit, but most of the cross openings are open and not closed, so it is easy to cause foreign matter to enter and affect its later disassembly process , disassembly is inconvenient and labor-intensive. Invention content: [0003] The technical problem to be solved by the prese...
