Description
Technical field
The utility model relates to and carries out fastening a kind of device to screw rod, specifically a kind of screw rod fastening sleeve.
Background technology
Through retrieval Patent documents of interest, not yet retrieve a kind of screw rod fastening sleeve identical with the utility model structure at present.Existing screw rod fastening method generally adopts two nuts and tight, and this kind of method comparatively bothers, and efficiency is lower, and also can wrap of screw rod with cloth and carry out fastening, this kind of method easily causes wearing and tearing to the screw thread on screw rod, makes troubles to production; So be necessary to be improved existing threaded rod fastening device, to meet the actual needs of existing production.
Summary of the invention
The purpose of this utility model will provide a kind of easy to use, a kind of screw rod fastening sleeve of available protecting screw flight.
Technical characteristic of the present utility model is: considering the basis that structure is simple, easy to use, bulk strength is high is designed to comprise sleeve body, sleeve body is provided with ratchet spanner installing hole, pin-and-hole, screw rod binding thread, and ratchet spanner installing hole is arranged in sleeve body; Screw rod binding thread is provided with at the inwall of sleeve body; Sleeve body is provided with pin-and-hole.
Described pin-and-hole is circular pin hole.
Described sleeve body is one and adopts chrome-molybdenum steel, chrome-vanadium steel, the 45# carbon steel wherein cylindrical shell made of a kind of material.
During use, first sleeve body is fastened to screw rod upper end, pin-and-hole is aimed at the cross recess of screw rod upper end, insert latch with fixed muffle, sleeve coordinates ratchet spanner to use, the ratchet spanner that turns clockwise drives sleeve rotating, drives screw rod fastening, after fastening, extract latch, be rotated counterclockwise ratchet spanner, removable bottom ratchet wheel spanner, and then pulling off sleeves.And insert latch time tight, be rotated counterclockwise sleeve and drive screw rod to rotate in the other direction, dismantle for screw rod.
The utility model has the advantages that: because sleeve coordinates ratchet spanner to use, thus it is time saving and energy saving that screw rod fastening sleeve is used; Owing to sleeve being provided with pin-and-hole with screw rod binding thread, thus make to coordinate between screw rod with sleeve tightr; Because structure is simple, easy to use, and sleeve can design plurality of specifications, is convenient for changing, and is suitable for the screw rod of different size, so there is very large practical and popularizing value.
