Technical field
The utility model relates to a kind of member connecting device, and is particularly a kind of when the installation or removal bolt, is used for the device that prevents that bolt from rotating.
Background technique
When two or more parts connect, often need to use bolt, nut to be fixed connection, in fastening process, need to bolt be fixed with spanner, it can not be rotated, then tighten the nut of the other end with another spanner, thereby a plurality of parts are fastenedly connected.But have in limited time in some special circumstances or installing space, be not easy to use wrench operated, this makes constructional difficulties.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, and a kind of simple in structure, easy to operate, space-saving device that prevents that bolt from rotating is provided.
For achieving the above object, the technical solution of the utility model is:
A kind of device that prevents that bolt from rotating, the plain cushion that comprises a screw portion outside that is sleeved on bolt, have at least one upwardly extending first boss on described plain cushion, described the first boss has a spline plane, matches with the head of described bolt and prevent its rotation in described spline plane.
Further, described the first boss is the long strip projection along at least one side setting of described plain cushion.
Further, described the first boss is two, is arranged on the both sides of described plain cushion.
Further, also be provided with the spline structure that coordinates with connected piece for preventing that plain cushion from rotating on described plain cushion.
Further, described spline structure is at least one second boss of downward-extension on described plain cushion.
Further, described the second boss is the long strip projection along at least one side setting of described plain cushion.
Further, described the second boss is positioned at the same side of described plain cushion or vertical side with described the first boss.
Further, this device is integrated the structural member of machine shaping.
Content to sum up, a kind of device that prevents that bolt from rotating provided by the utility model, simple in structure, be sleeved on the outside of bolt, utilize upwardly extending boss to coordinate with bolt head, and then prevent that bolt from rotating in tightening or unclamping the operation of nut, operate very simple and convenient, and do not need to use spanner, conserve space is not subjected to the restriction of installing space.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the structural representation after the utility model embodiment one assembles with connected piece;
