Abstract
The utility model provides an improved retained locknut having the basic structure that a cylindrical boss is arranged on the upper end surface of a nut, an annular groove is arranged in the cylindrical boss, and a retained ratchet clamp ring is inlaid in the annular groove. The improved retained locknut is characterized in that the lower end surface of the nut is provided with a flange spigot, and 3-8 elliptical grooves are uniformly distributed on the end surface of the spigot. The improved retained locknut is an substitute for the traditional sleeper upright post nut and has the advantages of compact structure and good press moulding integrity of the nut and the retained ratchet clamp ring; and as the lower end surface of the nut is provided with the flange spigot and locked paraboloidal grooves, the locknut can effectively prevent the joint of the nut and a railway track from loosening due to long-term vibration.
Description
Technical field
The utility model relates to a kind of improved retaining lock nut, belongs to machinery standard spare technical field, is particularly useful for railway concrete sleeper column bolt and uses.
Background technique
The retaining Rust-inhibiting nut mainly solve scyewed joint under the environment mal-condition as the vibrations that prevent in the corrosion of earth, water, air, acid, alkali etc. and the work, prevent that rust is dead, cause problems such as dismounting difficulty.Because train speed raising produces the enormous impact power of wheel to rail, strong high-frequency vibration makes concrete sleeper upright nut in groups loosening, and rail fastening lost efficacy, and caused the track geometry size to change, and seriously jeopardized traffic safety.For guaranteeing line quality, Ministry of Railways's standard-required concrete sleeper upright nut guarantees not move back under the long-term high-frequency vibration condition and buckles, not loosening, anti-corrosion.At present, domestic railway working system adopts plain nut to add traditional retaining method of spring washer mostly, can guarantee that in a short time moment of torsion is constant, do not move back button, but under the operating conditions of long-term strong high-frequency vibration, be difficult to guarantee the moment of torsion of regulation, therefore railway maintenance department will employ large quantities of maintenance mans and every day the concrete sleeper nut on the circuit in managing checked, multiple twisting, just it reaches 14 kilogram-metre moment of torsion standard-requireds of Ministry of Railways's regulation, to guarantee traffic safety.The patent applicant has applied for that some items are equipped with the Rust-inhibiting nut patent of sealed nylon circle in recent years, the technological scheme that the ratchet snap ring is set at sealed nylon circle end face is successively disclosed, make nut strengthen stopping function: and provided the ratchet snap ring that specifically is shaped as 2 of the eccentric annular steel discs of two semicircles or global shapes of " ratchet snap ring ", have a better effect in the practice.
Summary of the invention
The purpose of this utility model is to provide a kind of improved retaining lock nut, with further raising retaining and the effect that prevents to become flexible.
The technical solution of the utility model is achieved in that this improved retaining lock nut, its basic structure is provided with cylinder boss for the nut upper-end surface, have in the cylinder and stud with retaining ratchet snap ring in the annular groove, it is characterized in that: described nut lower end surface is provided with the flange seam, the uniform 3-8 oval recess that is provided with on the seam end face.
Described improved retaining lock nut, retaining ratchet snap ring is the inner pad that is ratchet shape, is embedded in the groove of inboard of nut body boss, also is provided with nylon pad in the groove.
Described improved retaining lock nut, uniform oval recess is parabolic on the nut seam end face.
Described improved retaining lock nut is 2-4 in the ratchet number of retaining ratchet snap ring.
Described improved retaining lock nut, retaining ratchet snap ring are the combination stacks of the snap ring of 2 ratchets.
Described improved retaining lock nut, the inside flanging of cylinder boss is fixed retaining ratchet snap ring on the nut end face.
The utility model is the replacement product of existing sleeper upright nut, and its advantage is, compact structure, and nut and three of retaining ratchet snap rings press-fit good integrity; Because the nut lower end surface is provided with flange seam and locking parabolic groove, can effectively prevent the long-term vibration of nut and becoming flexible of track binding site.It is mechanically various that it can also be widely used in industry, agricultural, communications and transportation, aviation, military affairs, construction engineering etc., especially seriously polluted, high-altitude, machinery run up and the alternation load impacts and macroseism power operating conditions under, more show its unique advantages, and can normally use in-50 ℃-+120 ℃ the temperature range, do not destroy its physics and mechanical property.

Embodiment
Describe technology contents of the present utility model in detail below in conjunction with embodiment and Fig. 1-3: nut is in actual course of working, below the cylinder boss of nut shown in Figure 11 upper-end surface and the nut flange seam 5 is set, the seam end face is provided with 3-8 paraboloidal oval recess 4 global formations, course of working is in the cylinder boss annular groove to be arranged on nut 1 upper-end surface, after being assembled with retaining ratchet snap ring 2, the inside flanging of cylindrical projection is with retaining ratchet snap ring 2, and nylon pad 3 is fixed in the nut annular groove; The inside flanging of nut cylinder boss is fixed.
Elongation technology scheme of the present utility model is that ratchet snap ring shown in Figure 2 is set to 2, with plural ratchet snap ring staggered superposition, also can reach goal of the invention during the nut assembling.
Foregoing description only proposes as a kind of embodiment of the improved retaining lock nut of the utility model technological scheme, not as the single restrictive condition to its structure.
