Description
Technical field
The utility model relates to a kind of screw, specifically relate to a kind of screw with pad, belong to mechanical connecting parts technical field.
Background technique
Screw is a kind of mechanically conventional fastening piece, but the screw that existing market is general is mostly standard piece, this standard piece screw itself is common, does not have locking, the function of protection matrix, therefore in use for preventing screw from occurring to loosen, usual needs configure in addition the elastic washer suitable with screw, plain washer etc. come with the use of, and these elastic washers, plain washer are mostly fabricated metals, in using process, easy and vehicle body matrix weares and teares, and destroys the protective layer of panel beating matrix; After long-time use, metal washer gets rusty easily, thus affects the fastening effect of screw and attractive in appearance, and in addition, use metal washer to not only increase weight and cost, and assembly process more complicated is loaded down with trivial details, locking abrasionproof effect is also undesirable.
When assembling, packing ring and screw are two parts be separated, and need the joint of gasket sleeve at screw, which increase the workload of people when assembling, and pad are also easy to landing; And some screw is fixed with packing ring, although can decrease the workload of people when assembling like this, this packing ring is fixed on screw, and original function of the packing ring being is restricted.
Summary of the invention
In order to overcome above-mentioned existing deficiency, the utility model provides a kind of screw that can not cause wearing and tearing, the pad not easily band pad of landing to the matrix of articles.
The utility model solves the technological scheme that its technical problem adopts: a kind of screw with pad, the screw connection portion comprise screw head, being connected with screw head, screw connection portion is provided with screw thread, transition part is provided with between described screw head and the screw thread being located at screw connection portion, the diameter of transition part is less than the diameter of screw thread, transition part cover has plastic washer, and the inner ring of plastic washer is polygonal, and the inner ring inscribe diameter of a circle of plastic washer is less than the diameter of screw thread.
The inner ring of described plastic washer is quadrilateral, Hexagon or Octagon.
The material of described plastic washer is nylon66 fiber.
The hardness of described plastic washer is less than the hardness being connected thing surface.
Described plastic washer adopts the machine shaping of high velocity ram machine one-shot forming technique.
Described plastic washer profile is circular, and the external diameter of packing ring is less than or equal to the external diameter of screw thread.
The described screw connection portion the other end relative with screw head is conehead structure or flush configuration.
The another side that described screw head is relative with screw connection portion offers and screws groove.
The described groove that screws is straight groove, cross recess or hexagonal flower shape groove.
The beneficial effects of the utility model are, devise plastic washer and replace traditional metal washer, install and use in process, and plastic washer can not cause wearing and tearing to vehicle body matrix, have better vehicle body matrix protective function; Long-time use also there will not be the situation of getting rusty, and ensure that the attractive in appearance of screw and fastening effect; Plastic washer endoporus adopts polygonal design, the inner ring inscribe diameter of a circle of plastic washer is less than the diameter of screw thread, become Multi-contact with screw thread, solve the problem that conventional metals packing ring endoporus is the easy landing of packing ring that circular design causes, improve the efficiency of assembling of screw; Adopt nylon66 fiber as the material of plastic spacer, ensure that the mechanical property of plastic washer, decrease weight and the cost of production of screw, meet automotive light weight technology trend; Plastic washer adopts high velocity ram machine one-shot forming technique, ensure that the quality of plastic washer, improves the manufacturing efficiency of plastic washer.
