In a kind of embodiment of the present utility model, a kind of screw is provided, comprise interconnective nut section 10 and screw part 30, nut section 10 side relative with screw part 30 is formed with and screws structure; This screw also comprises cap 50, and cap 50 selects nonmetallic material to make, and is connected with nut section 10 to be isolated from the outside with the structure that screws with described nut section 10.
In the above-mentioned screw of the utility model, it screws structure can be arbitrarily, if the installation and removal that can be convenient to screw all can, such as outer-hexagonal structure (not shown), interior hexagonal structure (as shown in Figure 1) or cross grooving (not shown) etc.
Above-mentioned socket head screw is isolated from the outside the structure that screws in nut section 10 by the cap 50 that adopts nonmetallic material and make, avoids it contact with external environment condition, avoids it by foreign matters from being blocked, or is corroded and become rusty extremely by rainwater, air.In this structure, the nut section 10 of cap that nonmetallic material are made 50 and metal material is essentially different on composition, can not intersect between the two and get rusty, and the cap 50 made of nonmetallic material carries out good sealing with nut section 10, as long as the lid of non-metallic material is not destroyed by force by external force, have the possibility that the socket head screw of this structure gets rusty minimum, the dismounting convenience that it has improved this socket head screw has improved overhaul of the equipments and maintenance efficiency.
Simultaneously, the screw that the application provides need not special substance, uses common material to get final product, and does not need to select stainless steel, and with respect to stainless steel, the cost of the screw of common material can be saved half, and even 2/3rds; And if the screw that the application provides adopts common material preparation, also lower than the cost of preparation stainless steel screw, the cap processing of non-metallic material is also very convenient for its technical maturity, cost of production, adopt the techniques such as once-through such as molding and forming to get final product, cost is also very low.Comprehensive, the screw that the application provides when having antirust function, can also decrease cost, improved economic benefit.
Preferably, the material of above-mentioned cap 50 includes but not limited to nylon, plastics or rubber material.The use of these materials can be played from the material source antirust effect.
In a kind of embodiment of the present utility model, in above-mentioned screw, cap 50 has the inner chamber with nut section 10 structure matching, and nut section 10 forms and screws the partial insertion of structure to the inner chamber of cap 50.Screw with this structure is not only easily made, and also can improve operation ease in the process of installing, dismantling, and then improves operating efficiency.
Preferably, in above-mentioned screw, the side wall inner surfaces gap of the sidewall outer surface of nut section 10 and cap 50 coordinates or interference fit.Screw with this this structure, nut section only need screw in or screw out to the inner chamber of the plastic cap 50 of nonmetallic material and get final product, and need not increase complicated assembly tool or equipment.
Wherein preferably, in above-mentioned screw, nut section 10 has cylindrical structural, and screwing structure is interior hexagonal structure or cross grooving structure, the sidewall outer surface of nut section 10 and the side wall inner surfaces screw-thread fit of cap 50 in this screw.In having the screw of this structure, by the sidewall outer surface threading in columniform nut section 10, and at the side wall inner surfaces machining internal thread of cap 50, in use, the cap 50 of non-metallic material is crossed screw thread with nut section to be tightened, to avoid the less air of external particle, aqueous vapor and foreign matter mud etc. to enter into cap 50, to reach better rust-proof effect, extend the using effect of this screw.
In a kind of embodiment of the present utility model, be provided with Sealing between the sidewall outer surface of nut section 10 and cap side wall inner surfaces in above-mentioned screw.Screw with this structure, be provided with Sealing between the sidewall outer surface of nut section 10 and cap side wall inner surfaces in screw, it can completely cut off foreign matter, moisture, air fully to the erosion of screw head, but also can prevent the risk that the nonmetallic material lid may get loose under mechanical shock or other bad working environments.The seal is not to be necessary element, and it can reasonably be selected according to the Environmental Conditions of screw.
Preferably, above-mentioned Sealing is sealer or fastening glue on the sidewall outer surface (external threaded surface) that is coated in cap 50 side wall inner surfaces (interior threaded surface) and/or nut section 10.The kind of sealer or fastening glue can the frequent dismounting of needs according to whether situation carry out choose reasonable.Employing sealer or fastening glue on the one hand can be so that make, install as Sealing, another is convenient, and it can also be more effectively that sidewall outer surface and the cap side wall inner surfaces of nut section 10 is bonded together to completely cut off foreign matter, moisture, air to the erosion of screw head.
In a kind of embodiment of the present utility model, the blocked part 51 that has annular in above-mentioned screw in the inner chamber of cap 50, blocked part 51 forms the ring-shaped step structure with the side wall inner surfaces of cap 50, and an end and blocked part that nut section 10 is inserted in the inner chamber of cap connect.
Screw with this structure, the blocked part 51 that has annular in the inner chamber of cap 50 makes in the inner chamber of the cap 50 that inserts nut section and also has segment space, is conducive to avoid cap 50 to be connected for a long time with nut section 10, inner negative pressure, the not easily detachable problem of cap of producing.
Preferably, in above-mentioned screw the internal diameter of blocked part 51 greater than the maximum inner diameter in structure.In this structure, can more be conducive to guarantee to insert the pressure in the inner chamber of cap 50 of nut section, so that the dismounting of cap 50 and nut section 10.
Preferably, arc-shaped transition or chamfered transition between blocked part and cap 50 side wall inner surfaces in the inner chamber of cap 50 in above-mentioned screw, nut section 10 has the structure that is complementary with this transition structure.Screw with this structure when mounted, can guarantee the integrity of cap 50 better, avoids the inwall of 10 pairs of caps 50 of nut section to cause damage, to extend the working life of cap 50.
