Abstract
The anti-loosening connecting piece is provided with a bolt and a nut which are matched with each other, the front end of the bolt is provided with a counter bore formed by connecting a tapered hole and a threaded hole, the part of the bolt with the tapered hole is provided with more than two locking grooves which extend along the axial direction of the bolt, the locking grooves penetrate through the tapered hole and the front end of the bolt, a plug is arranged in the counter bore at the front end of the bolt, and an external thread and a cone which are arranged on the plug are respectively matched with the threaded hole and the tapered hole which are arranged in the counter bore. The utility model provides a during the use of locking connector that moves, earlier by bolt, nut with two by the connector hookups, then with the screw hole hookups that external screw thread on the embolism and counter bore have again to screw up the embolism gradually, through the cooperation of cone and bell mouth on the embolism, the position that the bolt has the bell mouth produces elastic deformation, and then makes bolt and nut complex fasten more, prevents not hard up.
Description
Technical Field
The utility model relates to a connector, specifically speaking are locking connector that moves.
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.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a locking connector that moves, this locking connector that moves can be reliably linked by the connector to can avoid appearing not hard up phenomenon between the connector.
In order to achieve the above purpose, the utility model adopts the following scheme: the anti-loosening connecting piece is provided with a bolt and a nut which are matched with each other, the front end of the bolt is provided with a counter bore formed by connecting a tapered hole and a threaded hole, the part of the bolt with the tapered hole is provided with more than two locking grooves which extend along the axial direction of the bolt, the locking grooves penetrate through the tapered hole and the front end of the bolt, a plug is arranged in the counter bore at the front end of the bolt, and an external thread and a cone which are arranged on the plug are respectively matched with the threaded hole and the tapered hole which are arranged in the counter bore.
It is thus clear that by the above-mentioned scheme, the utility model provides a when locking connector that moves uses, earlier by bolt, nut with two by the connector hookups, then with the screw hole hookups that external screw thread on the embolism and counter bore have again to screw up the embolism gradually, through the cooperation of cone and bell mouth on the embolism, the bolt has the position of bell mouth and produces elastic deformation, and then makes bolt and nut complex fasten more, prevents not hard up.
The utility model discloses rational in infrastructure, use reliably, it is as the connector, especially is suitable for the hookup of the part or the part that have vibrations in the 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 schematic view of the embodiment shown in fig. 1 in a use state.
Detailed Description
The present invention will be further described with reference to the following specific embodiments and the accompanying drawings.
See fig. 1 and 2
The utility model provides a locking connector that moves has bolt 3 and nut 2 of mutually supporting, open the front end of bolt 3 has the counter bore that meets the constitution by bell mouth 3a and screw hole 3b, open on the position that bolt 3 has the bell mouth and have more than two along its axial extension's locking groove 3c, locking groove 3c link up the front end of bell mouth 3a and bolt 3, a embolism 1 is equipped with in the counter bore of bolt 3 front end, external screw thread 1b and the cone 1a that have on the embolism 1 cooperate with screw hole 3b and bell mouth 3a that the counter bore has respectively.
In this embodiment, the number of the locking grooves 3c on the bolt 3 is four to six, and the locking grooves 3c are uniformly distributed along the circumferential direction of the bolt 3.
See fig. 1, 3
The utility model provides a during the use of locking connector that moves, earlier by bolt 3, nut 2 with two by connector 4, 5 hookups, then the screw hole 3b hookups that external screw thread 1b on 1 with the counter bore has of embolism again to screw up 1 gradually with embolism, through the cooperation of 1 last cone 1a of embolism and bell mouth 3a, the position that bolt 3 has the bell mouth produces little elastic deformation, makes bolt 3 and 2 complex fastenings more of nut, plays and prevents not hard up the effect.
Claims (2)
1. Locking connector that moves has the bolt and the nut of mutually supporting, its characterized in that: the front end of the bolt is provided with a counter bore formed by connecting a tapered hole and a threaded hole, the part of the bolt with the tapered hole is provided with more than two locking grooves extending along the axial direction of the bolt, the locking grooves penetrate through the tapered hole and the front end of the bolt, a plug is arranged in the counter bore at the front end of the bolt, and external threads and a cone on the plug are respectively matched with the threaded hole and the tapered hole of the counter bore.
2. The anti-loosening coupling according to claim 1, wherein: the locking grooves on the bolt are four to six, and the locking grooves are uniformly distributed along the circumferential direction of the bolt.
