Abstract
The invention relates to a stop threaded sleeve. The stop threaded sleeve comprises a threaded sleeve body (1) and a stop ring (4). The end of the threaded sleeve body (1) is provided with protrusions (2), the distance from the protrusions (2) to the axis of the threaded sleeve body is smaller than the outer diameter of a thread of the threaded sleeve, the stop ring (5) can be fixed onto a part where the threaded sleeve body is installed, and pits (6) matched with the protrusions (2) arranged at the end of the threaded sleeve body are formed in the stop ring (5). The stop threaded sleeve is simple in structure and easy to operate, the threaded sleeve is effectively prevented from rotating in the screw installation process and the use reliability is guaranteed.
Description
Technical field
The present invention relates to a kind of stop swivel nut.
Background technique
At aviation field, in order to reduce aircraft product weight, the material of some parts adopts light-duty alloy, as magnalium.The material of these materials own is softer, and the screw of installing above material at these easily causes screw thread breakage, screw is installed firm not, affects functional reliability.Therefore, in design, generally can swivel nut be set in the position connecting, the material hardness of swivel nut is larger, and swivel nut is threaded by large diameter with parts, is provided with the screw thread for mounting screw in swivel nut inside.Arranging of swivel nut solved the softer unstable problem of material mounting screw of material, but in installation process, installing after swivel nut, being screwed in screw process, easily there is the situation of swivel nut self rotation, thereby do not ensure that screw fastening puts in place, affect the operational safety of associated components.
Summary of the invention
The object of this invention is to provide a kind of swivel nut, can prevent that swivel nut self rotates in installation process, ensure operational safety.
Technological scheme of the present invention is, described stop swivel nut comprises swivel nut body and stopper ring, the end of described swivel nut body is provided with projection, the distance in described protruding distance swivel nut axle center is less than the external diameter of swivel nut screw thread, stopper ring can be fixed on the parts of swivel nut installation, and the inside of described stopper ring is provided with the pit matching with the projection of swivel nut end setting.Described projection and pit are multiple, or the spline cooperatively interacting.On the external diameter of stopper ring, be provided with projection and also coordinate and be arranged on parts, described projection, for being symmetrical arranged, can be also symmetrically arranged spline.The other end of swivel nut body is provided with six uniform grooves.
The present invention is provided with projection or spline on swivel nut body, is fixed with stopper ring on parts, by coordinating, makes to be fixed after the installation of swivel nut body, prevents self rotating in the time screwing in screw.Six grooves that the other end of swivel nut body arranges, are being screwed into after screw, can carry out application of force distortion to swivel nut body end, play the effect of lock screw.The present invention is simple in structure, easy operating, and effectively prevent that swivel nut self rotates in mounting screw process, ensure operational safety.
Brief description of the drawings
Fig. 1 is swivel nut body structure schematic diagram of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of stopper ring of the present invention;
Fig. 4 is the side view of Fig. 3.
Embodiment
As shown in the figure, stop swivel nut comprises swivel nut body 1 and stopper ring 4, the end of described swivel nut body 1 is provided with projection 2, the distance in the distance swivel nut axle center of described projection 2 is less than the external diameter of swivel nut screw thread, stopper ring 5 can be fixed on the parts of swivel nut installation, and the inside of described stopper ring 5 is provided with the pit 5 matching with the projection 2 of swivel nut end setting.Described projection 2 and pit 5 are multiple, or the spline cooperatively interacting.On the external diameter of stopper ring 4, be provided with projection 6 and also coordinate and be arranged on parts, described projection 6, for being symmetrical arranged, can be also symmetrically arranged spline.The other end of swivel nut body 1 is provided with six uniform grooves 3.
