Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the connector of the present invention;
in the figure: 1 spiral spring, 2 connecting pieces, 3 chamfers, 4 spiral sections, 5 barbs and 6 springs.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the coil spring for the piston oil ring comprises a coil spring 1, wherein the head end and the tail end of the coil spring are connected through a connecting piece 2, the connecting piece comprises an arc-shaped silk thread, and the silk thread is a steel wire or an iron wire. One end of the silk thread is provided with a chamfer 3, one end of the spiral spring is clamped by the chamfer, and the other end of the silk thread is inserted into the other end of the spiral spring. Make the one end of silk thread fixed with coil spring, insert the coil spring with the silk thread other end again, utilize coil spring's elasticity, realize the spacing conflict to the silk thread other end, guaranteed the connection at coil spring head and the tail both ends, and then be convenient for the integral erection inboard in the oil ring.
Further, one end, provided with a chamfer, of the silk thread is provided with a spiral section 4, the tail end of the spiral section is provided with a chamfer, and the spiral section is clamped with the spiral spring. And one end of the silk thread is stably connected with the spiral spring.
Furthermore, the other end of silk thread is provided with barb 5, the size of barb is less than coil spring's aperture, the barb is close to one side of silk thread and is provided with spring 6, barb, spring all support with coil spring mutually.
The utility model discloses a theory of operation does: have the silk thread one end precession coil spring's of chamfer one end, at this moment, chamfer department blocks with coil spring mutually, the spiral section is also adaptability to be blocked simultaneously, guaranteed silk thread one end and coil spring's spacing fixed, the silk thread other end inserts coil spring, utilize coil spring's elasticity, realize spacing firm, furthermore, the barb of the silk thread other end can catch on coil spring, realize firm the connection, connect coil spring's end to end on the whole, it is long when having guaranteed that installation and use of being convenient for of holistic spiral spring prop.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
