Abstract
The utility model discloses a locking mechanism for mechanical bolts and nuts.A circle pit is arranged at the center of the bottom of a locking nut.Radioactive grooves are arranged around the circle pit.The depth of the circle pit is slightly larger than that of the radioactive grooves.A keyway is arranged on the upper plane of a fastening nut and the width of the keyway is the same with that of the radioactive grooves.The spring pin has the same width with that of the radioactive grooves and the keyway.The head of the spring pin is equipped with a U-shaped convexity.The fastening nut is connected with the bolt and the bolt is in close connection with the fastening nut.The bolt arranged at the upper end of the fastening nut is equipped with the locking nut.The locking nut is further screwed up and the radioactive grooves are in alignment with the keyway of the fastening nut.The fastening nut is kept in a tightening state.The U-shaped convexity at the head of the spring pin is set to be upward and inward and the spring pin is inserted into the grooves and the keyway which are in alignment with each other.The U-shaped convexity at the head of the spring pin is finally clamped in the circle pit arranged at the center of the bottom of the locking nut.
Description
Technical field
The utility model relates to a kind of locking mechanism of bolts and nuts, and the locking mechanism of particularly a kind of mechanical bolt and nut belongs to mechanical connection and locking technical field.
Background technique
In machinery; the connection overwhelming majority between the part moved screw thread and realizes being connected with nut; but, because machinery can produce certain vibrations in the process of operation; so; after using after a while, usually can produce lax phenomenon thus between the bolts and nuts, once the generation of this situation; just might make the equipment can't proper functioning, even cause other great security incident.
In order to overcome the relaxation phenomenon that occurs between the bolts and nuts, at present, some bolts and nuts locking mechanisms and locking mode arise at the historic moment, though the locking mechanism of these bolts and nuts has solved corresponding problem to a certain extent, but, also have some defectives.
The model utility content
The purpose of this utility model is: the locking mechanism of a kind of mechanical bolt and nut is provided, overcomes existing more existing defectives of bolts and nuts locking mechanism.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: the locking mechanism of a kind of mechanical bolt and nut, and it is made up of bolt, And jack panel, spring pin, tightening nut; Locking mechanism has a And jack panel, and making at the bottom center position of And jack panel has circular pit, and making around the circular pit has radiation groove, the degree of depth of circular pit to be slightly larger than the degree of depth of radiation groove; Making on plane on the tightening nut has keyway, and keyway equates with the width of radiation groove; The width of spring pin equates that with the width of radiation groove, keyway the head of spring pin has the projection of a U type; Annexation between them is: use tightening nut to be connected with bolt, and make between bolt and the tightening nut and to form the relation that is fastenedly connected, the And jack panel is installed on the outstanding bolt in tightening nut top, continue to tighten the And jack panel, and radiation groove and the keyway above the tightening nut are aligned, make the And jack panel be in tight condition, with the projection of the head U type of spring pin upwards, inwards, spring pin is inserted in the groove and keyway align mutually, be fastened in the bottom surface circular pit of And jack panel until projection with the head U type of spring pin.
Beneficial effect: the utility model is because by the degrees of freedom of circumferentially mutually the rotating restriction of spring pin with And jack panel and tightening nut, so, can reach the purpose of locking, simultaneously, the utlity model has simple in structure, the advantage of installation, convenient disassembly.
