Embodiment Construction
[0023] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0024] The schematic diagram of the locking ring of the present invention is as figure 2 As shown, it includes the upper locking ring 5, the middle locking ring 12, and the lower locking ring 21; the schematic diagrams of each locking ring are as follows image 3 Figure 4 Figure 5 shown; wherein, the polyhedron 7 is a hexagon, evenly distributed on the outer circumferential surface of each locking ring, the slot body 8 is composed of a circle and a rectangle, and has a round hole slot 4, a round hole slot 4 and a slot body 8 composite, opened in the middle of the rectangular slot 9 of the card slot body 8. The upper middle helical surface 19 and the lower middle helical surface 20 of the middle locking ring 12 have different helical directions. The helical surface 11 of the upper locking ring 5 and the middle and upper helical surface 19 of the middle ...

The invention belongs to the technical field of design of mechanical structures, and relates to a locking ring. The locking ring comprises an upper locking ring (5), a middle locking ring (12) and a lower locking ring (21), wherein the upper locking ring (5), the middle locking ring (12) and the lower locking ring (21) are sequentially connected together through spiral pairs; the middle upper spiral surface (19) of the upper part of the middle locking ring (12) is matched with the first spiral surface (11) arranged under the upper locking ring (5) so as to form the corresponding spiral pair; the middle lower spiral surface (20) of the lower part of the middle locking ring is matched with the second spiral surface (27) of the lower locking ring (21) so as to form the corresponding spiral pair; and hexagonal, round and rectangular tanks as well as a round hole slot (4) compounded with a clamp slot body (8) are distributed on the outer circumferential surfaces of the various locking rings. The locking ring disclosed by the invention has a novel structure, and compared with a conventional single spiral pair, the two pairs of spiral surfaces are locked in the axial direction and the adjustable distance can be greater, and thus, the technical problems of shorter locking adjustment distance, small locking force and poor adaptability of current locking rings are solved, the adaptability is stronger and the use range is wide.
Description
technical field [0001] The invention belongs to the field of machinery and relates to a locking ring. Background technique [0002] Standard locking rings available on the market, opinion figure 1 . The center of the locking ring 1 is a through hole 2, the side perpendicular to the shaft is a helical surface 3, and the outer peripheral surface parallel to the shaft has a circular hole groove 4. For the same two locking rings 1, the helical surfaces 3 are placed opposite each other, and the axial locking distance is adjusted only by the change of the linear distance after the relative rotation of the pair of helical surfaces. The locking distance is relatively short. Once the adjustment distance increases, the The screw adjustment distance of the helical surfaces of the two locking rings cannot be locked. In addition, (see figure 1 ), using a round-head hook wrench to loosen and tighten the locking ring, but it is found in the use of loading equipment: ①Once the locking r...
