Abstract
The utility model relates to a four-jaw coupling. The four-jaw coupling comprises an outer shell of the coupling, an inner sleeve and an inner hexangular set screw, wherein an inner hole of the outer shell of the coupling is designed to be a conical hole, two half threaded holes are formed in the outer end face, an outer circle of the inner sleeve is designed to be a taper outer circle, the size of an inner hole of the inner sleeve is the same with that of a shaft which is matched with the inner hole, two half unthreaded holes are formed in the outer end face, and a groove is formed in the inner sleeve along the radial direction. The four-jaw coupling is simple in structure, convenient to assemble, light and handy, and practical.
Description
Technical field
The utility model relates to the four paws coupling on a kind of chemical pump.
Background technique
At present, its internal diameter of the coupling of existing pump adopts cooperating of H7/js6 with axle on the market, and the length of endoporus is identical with the length of axle, and is hard especially when assembling like this, and the waste material.
Summary of the invention
The purpose of this utility model is the defective for prior art, and a kind of four paws coupling of easy to assembly, light and handy practicality is provided.
The technical solution of the utility model is as follows: the four paws coupling comprises coupler casing, inner sleeve and interior hexagonal Cock screw, the bore design of coupler casing becomes taper hole, the exterior edge face is provided with two partial thread holes, the cylindrical of inner sleeve is made as the tapering cylindrical, the endoporus of inner sleeve is identical with the shaft size that will join, the exterior edge face is provided with two and half unthreaded holes, and inner sleeve radially is provided with a groove.
The utility model has the advantages that: practicality simple in structure, easy to assembly, light and handy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of coupler casing among Fig. 1;
Fig. 3 is that A among Fig. 2 is to view;
Fig. 4 is the structural representation of inner sleeve among Fig. 1;
Fig. 5 is that B among Fig. 4 is to view.
Embodiment
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, it comprises coupler casing 1, inner sleeve 2 and interior hexagonal Cock screw 3, the bore design of coupler casing 1 becomes taper hole 4, the exterior edge face is provided with two partial thread holes 5, the cylindrical of inner sleeve 2 is made as tapering cylindrical 7, the endoporus of inner sleeve 2 is identical with the shaft size that will join, and the exterior edge face is provided with two and half unthreaded holes 6, and inner sleeve 2 radially is provided with a groove 8.The internal diameter of inner sleeve 2 can because elasticity becomes larger, be conducive to be inserted on the axle like this.
During assembling, half unthreaded hole 6 of inner sleeve 2 is aimed at the partial thread hole of coupler casing 1, put into coupler casing 1, note the front-end face of inner sleeve 2 apart from the front-end face 2-4mm of coupler casing 1, hexagonal Cock screw 3 in screwing in, owing in coupler casing 1 first tapped hole 5 screw thread is arranged, do not have screw thread in inner sleeve 2 first unthreaded holes 6, hexagonal Cock screw 3 in the turn can make inner sleeve 2 backward mobile, the endoporus of inner sleeve 2 dwindles step by step like this, at last shaft locking.
