Abstract
The utility model provides a locking rustproof nut which has a basic structure that one end surface of the nut is provided with a cylinder bulge. An annular notch is arranged in the cylinder, a nylon sealing ring and a locking ratchet clamping ring are laid in the notch, and the locking ratchet clamping ring is in integration structure and is provided with two rings of the ratchet. The utility model has the advantages that the manufacturing production of the nut is even easier to realize and the rustiness and the looseness of the nut and a screw bolt can be effectively prevented. In addition, the utility model is particularly suitable for mechanical fixing in mine and downhole operations.
Description
The utility model relates to a kind of retaining Rust-inhibiting nut, belongs to machinery standard spare technical field.
For the corrosion that prevents nut or loosening, I have applied for two Rust-inhibiting nut patents that the sealed nylon circle is housed in recent years, in " 94247301 " patent, disclose the technological scheme that the ratchet snap ring is set at sealed nylon circle end face, made nut strengthen stopping function; And provided " ratchet snap ring " specifically be shaped as the eccentric annular steel discs of two semicircles, processing and install all not too easyly in the practice, and permanent vibration also might misplace.
The purpose of this utility model is to provide a kind of retaining Rust-inhibiting nut that is provided with the ratchet snap ring of global shape, to enhance productivity and further to improve the retaining effect.
The technical solution of the utility model is achieved in that this its basic structure of retaining Rust-inhibiting nut is that end face of nut is provided with cylindrical projection, annular groove is arranged in the cylinder, stud with sealed nylon circle and retaining ratchet snap ring in the groove, described retaining ratchet snap ring is structure as a whole the annulus of two ratchets is set.
The ratchet snap ring of described retaining Rust-inhibiting nut can place the sealed nylon circle above or below.
Major advantage of the present utility model is to make the easier realization of processing of this nut, can effectively prevent the corrosion of nut and bolt and become flexible, is particularly useful for the mechanical fixation of mine, underground work.
Describe technology contents of the present utility model in detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 is that cross-sectional view Fig. 2 of the utility model retaining Rust-inhibiting nut is among the ratchet snap ring shape schematic representation figure of the present utility model for retaining Rust-inhibiting nut top view structural representation Fig. 3 of the present utility model:
1, cylindrical projection 2, ratchet snap ring 3, sealed nylon circle 4, nut
In actual applications, ratchet snap ring 2 can place sealed nylon circle 3 above or below because the ratchet snap ring be whole processing, advantage is that the retaining Rust-inhibiting nut is easy to assembly and retaining is effective.
