Abstract
Protecting sleeve for thread.Along with the development petrochemical equipment of science and technology is more and more towards large scale development; its fastener used also more and more maximizes; because the screw thread that fastener is outside exposed is easy to damage in transport and disassembly process; affect the use of fastener; therefore the protection problem of fastener is more and more subject to the attention of user, because plastic strength is poor, in transport and disassembly process; as excessive external impact force, easily because itself weakening the protection of its double thread.A kind of protecting sleeve for thread; its composition comprises: screw thread bush (1); described screw thread bush and seal cover cap (2) are welded to connect; one end of described screw thread bush processes threaded sleeve for the end that spins; the seal cover cap of the other end is closed end; the described screw thread bush end that spins is processed with negative thread, and is processed with through hole in the closed end side of described screw thread bush.The utility model is applied to the fender guard of the exposed screw thread of the large-scale fastener of protection.
Description
technical field:
the utility model relates to a kind of protecting sleeve for thread, for petrochemical equipment transport and the protection of the exposed screw thread of the medium-and-large-sized fastener of installation process.
background technology:
along with the development petrochemical equipment of science and technology is more and more towards large scale development, its fastener used also more and more maximizes, because the screw thread that fastener is outside exposed is easy to damage in transport and disassembly process, affect the use of fastener, therefore the attention of the protection problem of fastener more and more user, be usually used in the protecting sleeve for thread of the exposed screw thread protection of fastener in petrochemical equipment transport and disassembly process at present, general employing plastic whorl protecting sleeve, because plastic strength is poor, in transport and installation process, as excessive external impact force, the easy protection because itself weakening its double thread, the fastener adopted due to distinct device is different, and general consumption is less, and the manufacture of plastic whorl protecting sleeve need have corresponding mould, and mould is expensive, therefore should not manufacture voluntarily by equipment manufacturing, also not easily purchases.
utility model content:
the purpose of this utility model is to provide a kind of protecting sleeve for thread.
above-mentioned object is realized by following technical scheme:
a kind of protecting sleeve for thread; its composition comprises: screw thread bush; described screw thread bush and seal cover cap are welded to connect; one end of described screw thread bush processes threaded sleeve for the end that spins; the seal cover cap of the other end is closed end; the described screw thread bush end that spins is processed with negative thread, and is processed with through hole in the closed end side of described screw thread bush.
described protecting sleeve for thread, described screw thread bush is hollow cylinder, and described seal cover cap is the cylinder that diameter is less than described screw thread bush.
the beneficial effects of the utility model:
1. the utility model belongs to the fender guard for the protection of the exposed screw thread of large-scale fastener in petrochemical equipment transport and disassembly process; overcome the deficiency of existing plastic whorl protecting sleeve, provide a kind of and can protect fastener threads, easily processing very well, not by the protecting sleeve for thread of mould restriction.
the utility model comprises one end and processes threaded sleeve for the end that spins; the seal cover cap of the other end is closed end; sleeve and seal cover cap are welded to connect; spin end according to fastener specification machining internal thread; and at closed end side processing through hole; through hole is used for binding thread protecting sleeve, on the Problems existing of foregoing plastics protecting sleeve for thread, efficiently solves the problem that the outside exposed screw thread of fastener is easy to damage in transport and disassembly process.
the utility model intensity ratio plastic strength is in the past tough, in transport and installation process, as excessive external impact force, can play the protection of double thread, practical and convenient, cost-saving.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of protecting sleeve for thread; its composition comprises: screw thread bush 1; described screw thread bush and seal cover cap 2 are welded to connect; one end of described screw thread bush processes threaded sleeve for the end that spins; the seal cover cap of the other end is closed end; the described screw thread bush end that spins is processed with negative thread, and is processed with through hole in the closed end side of described screw thread bush.
embodiment 2:
protecting sleeve for thread according to embodiment 1, described screw thread bush is hollow cylinder, and described seal cover cap is the cylinder that diameter is less than described screw thread bush.
Claims (2)
1. a protecting sleeve for thread; its composition comprises: screw thread bush; it is characterized in that: described screw thread bush and seal cover cap are welded to connect; one end of described screw thread bush processes threaded sleeve for the end that spins; the seal cover cap of the other end is closed end; the described screw thread bush end that spins is processed with negative thread, and is processed with through hole in the closed end side of described screw thread bush.
2. protecting sleeve for thread according to claim 1, is characterized in that: described screw thread bush is hollow cylinder, and described seal cover cap is the cylinder that diameter is less than described screw thread bush.
