The utility model discloses the technological effect that can reach is: the utility model discloses a spacing limiting plate in spacing jack and spacing slot makes to connect cap and bolted connection can not rotate relatively after good, consequently is difficult for appearing not hard up.
Drawings
The invention will be described in further detail with reference to the following drawings and detailed description:
fig. 1 is a schematic structural view of a nut of the present invention capable of automatic lubrication;
FIG. 2 is an enlarged view of portion A of FIG. 1;
fig. 3 is an exploded view of a self-lubricating nut of the present invention;
fig. 4 is an enlarged view of a portion B of fig. 3.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
See fig. 1-4.
A nut capable of automatically lubricating comprises a bolt 1 and a nut body, wherein the nut body comprises a connecting cap 2, a limiting plate 4 and a check washer 5; the connecting cap 2 is in threaded connection with the bolt 1; the bottom of the bolt 1 is provided with a limiting slot 6 matched with the limiting plate 4; the connecting cap 2 is provided with a limiting jack 7; the limiting plate 4 is inserted into the limiting jack 7 and the limiting slot 6; the connecting cap 2 is in threaded connection with a connecting cover 3 which limits the limiting plate 4 in the limiting jack 7 and the limiting slot 6; the anti-loosening gasket 5 is connected between the connecting cover 3 and the connecting cap 2.
Specifically, the outer end of the connecting cover 3 is provided with a cross-shaped rotating groove 8.
Specifically, the bottom of the bolt 1 is provided with 4 limiting slots 6.
Specifically, the limiting plate 4 is in a shape of a straight line, and the corresponding limiting insertion hole 7 and the corresponding limiting slot 6 are also in a shape of a straight line.
Specifically, the bottom end of the bolt 1 is provided with a first external thread 11; the bolt 1 is in threaded connection with the connecting cap 2 through a first external thread 11; the bottom end of the connecting cap 2 is provided with a second external thread 12; the connecting cap 2 is in threaded connection with the connecting cover 3 through a second external thread 12; the first external thread 11 and the second external thread 12 are in the same direction.
Instructions for use: in the use of the utility model (refer to fig. 1), firstly, the bottom end of the bolt 1 is passed through a fixture 21 to be fixed, then the connecting cap 2 is connected with the bottom end of the bolt 1 in a threaded manner, and the limiting plate 4 is inserted into the limiting jack 7 and the limiting slot 6, when the limiting plate 4 is inserted, the anti-loosening gasket 5 is placed at the bottom end of the connecting cap 2 and the connecting cap 3 is screwed on the connecting cap 2, at the moment, the limiting plate 4 is limited between the bolt 1 and the connecting cap 3, namely, the limiting plate 4 is limited in the limiting jack 7 and the limiting slot 6, and the nut body connection is completed; because the limiting plate 4 is limited in the limiting jack 7 and the limiting slot 6, the connecting cap 2 and the bolt 1 cannot rotate relatively (namely, the bolt 1 must drive the connecting cap 2 to rotate together when rotating), thereby achieving the technical effect of looseness prevention. Because the screwing degrees of the connecting cap 2 are different easily, 4 limiting slots 6 are formed in the bottom of the bolt 1, and the limiting plate 4 can pass through the limiting jacks 7 and be inserted into different limiting slots 6; in order to facilitate the connection of the connecting cover 3, the outer end of the connecting cover 3 is provided with a cross-shaped rotating groove 8, and the connecting cover 3 can be rotated by a cross-shaped wrench; in order to prevent the connecting cap 2 from being unscrewed (i.e. the connection between the bolt 1 and the connecting cap 2 becomes loose) during the screwing process of the connecting cover 3, the first external thread 11 and the second external thread 12 are preferably same in the screwing direction; when the utility model discloses bolt 1 appears connecting the dead problem of lock with connecting cap 2, can be through the inside lubricating oil that adds of spacing jack 7 to it is lubricated, be favorable to rotating and connect cap 2.
