Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of new comb needle type needle roller, knot Structure is simple, easy installation and removal, it is ensured that the needle point of pricker can easily be changed residing for the needle point of pricker on same circumference Circumferential spread diameter.

To reach above-mentioned purpose, the technical solution of the utility model is：A kind of new comb needle type needle roller, including axle, cylinder, Pricker, the cylinder are coordinated by key and coupled with axle, and the cylinder outer marginal circumference is laid with what several length directions ran through Dove tail groove, the dove tail groove internal clearance, which coordinates, is provided with dovetail key, among the dovetail key top surface along its length at equal intervals Provided with tapped blind hole, the pricker outer wall bottom is provided with external screw thread and is provided with bulge loop above the external screw thread, the external screw thread and Tapped blind hole coordinates connection and bulge loop supports to dovetail key top surface, the cylinder both ends and is equipped with annular baffle, and the baffle plate leads to Several screws for crossing circumference uniform distribution are connected and fixed with cylinder, and the baffle plate is upper and lower two splitted structure and inwall is caught in axle outer wall Annular groove in.

The external diameter of the baffle plate exceedes the bottom surface of dove tail groove.

The external diameter of the baffle plate is less than the external diameter of cylinder.

Circumference uniform distribution is provided with the through hole passed through for screw on the baffle plate.

Equal circumference uniform distribution is provided with the screwed hole coordinated with through hole in the cylinder both ends of the surface.

The beneficial effects of the utility model are：The utility model is simple in construction, pricker easy installation and removal, changes quick letter It is single, the needle point of pricker is can ensure that on same circumference, can be by changing the pricker of different length, to change the needle point of pricker institute The circumferential spread diameter at place, apply to the various operating modes being actually needed, it is versatile, it is practical, it is worthy to be popularized.
