Abstract
The anti-loosening combined connecting piece is provided with a bolt and a nut which are matched with each other, the upper end face of the nut is provided with a plurality of clamping grooves, the clamping grooves extend along the radial direction of the nut, the clamping grooves are uniformly distributed along the circumferential direction of the nut, the anti-loosening combined connecting piece is also provided with a locking nut, the lower end face of the locking nut is provided with more than one group of convex teeth, and the convex teeth and the clamping grooves on the nut are in a matching relation. When the anti-loosening connecting piece is used, the two connected pieces are connected by the bolt and the nut, then the locking nut is combined with the bolt, and the locking nut is gradually screwed down, so that the convex teeth on the locking nut enter the clamping grooves on the nut, and the nut can be prevented from loosening through the matching of the convex teeth and the clamping grooves.
Description
Technical Field
The invention relates to a connecting piece, in particular to an anti-loosening combined connecting piece.
Background
At present, a commonly used coupling member comprises the bolt and the nut of mutually supporting, this kind of coupling member can be reliable with two parts or the tight hookup of part, but the not enough of existence is, when the part or the part that are linked up have more frequent vibrations in operating condition, can appear small relative rotation between bolt and nut, small relative rotation accumulates gradually, can lead to appearing not hard up phenomenon between the part or the part of interconnect, if not handle in time, can influence working property, can lead to the occurence of failure when serious.
Disclosure of Invention
The invention aims to provide a loosening-preventing combined connecting piece, which can reliably connect connected pieces and can avoid the loosening phenomenon between the connected pieces.
In order to achieve the purpose, the invention adopts the following scheme: the anti-loosening combined connecting piece is provided with a bolt and a nut which are matched with each other, the upper end face of the nut is provided with a plurality of clamping grooves, the clamping grooves extend along the radial direction of the nut, the clamping grooves are uniformly distributed along the circumferential direction of the nut, the anti-loosening combined connecting piece is also provided with a locking nut matched with the bolt, the lower end face of the locking nut is provided with more than one group of convex teeth, and the convex teeth and the clamping grooves on the nut are matched with each other.
According to the scheme, when the anti-loosening connecting piece is used, the two connected pieces are connected through the bolt and the nut, then the locking nut is combined with the bolt and is gradually screwed down, the convex teeth on the locking nut enter the clamping grooves on the nut, and the nut can be prevented from loosening through the matching of the convex teeth and the clamping grooves.
The invention has reasonable structure and reliable use, and is used as a connecting piece, in particular suitable for connecting parts or components with vibration in work.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
fig. 3 is a sectional view B-B of fig. 1.
Detailed Description
The invention is further illustrated by the following specific examples and the accompanying drawings.
See fig. 1, 2, 3
The anti-loosening combined connecting piece provided by the invention is provided with a bolt 1 and a nut 2 which are mutually matched, the upper end surface of the nut 2 is provided with a plurality of clamping grooves 2a, the clamping grooves 2a extend along the radial direction of the nut 2, and the clamping grooves 2a are uniformly distributed along the circumferential direction of the nut 2. The anti-loosening combined connecting piece is also provided with a locking nut 3 matched with the bolt 1, the lower end face of the locking nut 3 is provided with more than one group of convex teeth 3a, and the convex teeth 3a are matched with the clamping grooves 2a on the nut.
In this embodiment, two to three sets of convex teeth 3a are provided on the lower end surface of the lock nut 3, each set of convex teeth 3a is two to three, and each set of convex teeth 3a is uniformly distributed along the circumferential direction of the lock nut 3.
See FIG. 1
In this embodiment, a plurality of protrusions 1b are uniformly distributed on the head supporting surface 1a of the bolt 1. When the head bearing surface 1a of the bolt 1 is matched with the nut 2 to clamp a connected piece, the bulge 1b presses on the connected piece, so that the friction force can be increased, and the looseness can be better prevented.
