Abstract

Rise core the utility model discloses a kind of pipe fitting internal expansion type, it includes the core ontology that rises, the core ontology that rises is made of the piston ring of rise core pipe and the both ends that the core pipe that rises is arranged in, rise and is provided with two or more the slot that helps to rise on core ontology, frustum of a cone hole is provided with inside the piston ring, the small end diameter in the frustum of a cone hole is equal with the centralized positioning bore dia to rise in core pipe, and the core ontology that rises is an integral molding structure, and is provided with card slot outside the piston ring.The utility model has structure simple, easy to use, its not only good positioning effect, and does not hurt pipe fitting inner wall, durable advantage.

Description

A kind of pipe fitting internal expansion type rises core
Technical field
Rise core the utility model relates to a kind of pipe fitting internal expansion type, belongs to pipe fitting technical field of processing equipment.
Background technique
In the prior art, when being processed to pipe fitting, usually using rack positioning pipe fitting or the core that rises of decorative pearl on top of an official cap formula Pipe fitting is positioned, it is not firm that the former positions, and the latter is not durable and is easy to damage pipe fitting inner wall.
Utility model content
Rise core the technical problem to be solved by the utility model is to provide a kind of pipe fitting internal expansion type, its structure order makes With convenient, not only good positioning effect, and do not hurt pipe fitting inner wall, it is durable.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of pipe fitting internal expansion type rises core, it includes the core ontology that rises, and the described core ontology that rises core pipe and is arranged in the core that rises by rising The piston ring at the both ends of pipe forms, two or more the slot that helps to rise is provided on the core ontology that rises, is provided with circle inside the piston ring Cone machine hole, the small end diameter in the frustum of a cone hole are equal with the centralized positioning bore dia to rise in core pipe.
The core ontology that rises is an integral molding structure.
Card slot is provided with outside the piston ring.
Adjacent two help to rise slot, a piston ring through rise core pipe and core pipe one end of rising, and another through rising The piston ring of core pipe and the core pipe other end that rises.
It is easy to use the beneficial effects of the utility model are: the utility model structure is simple, its not only good positioning effect, And do not hurt pipe fitting inner wall, it is durable;Being tested the core that rises can be Reusability 20000 time or more.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model;
Fig. 2 is the utility model main view;
Fig. 3 is the utility model side view.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below Specific embodiment and diagram are closed, the utility model is further described.
The core as shown in Figure 1-3, a kind of pipe fitting internal expansion type rises, it includes the core ontology that rises, and the core ontology that rises is by the core pipe 1 that rises It is formed with the piston ring 2 at the both ends that the core pipe 1 that rises is arranged in, two or more the slot 3 that helps to rise is provided on the core ontology that rises, it is described Frustum of a cone hole 4 is provided with inside piston ring 2, the small end diameter in the frustum of a cone hole 4 and the center positioning hole 5 to rise in core pipe 1 are straight Diameter is equal.
The core ontology that rises is an integral molding structure.
Card slot 6 is provided with outside the piston ring 2.
Adjacent two help to rise slot 3, and a piston ring 2 through rise core pipe 1 and 1 one end of core pipe of rising, another passes through Wear the piston ring 2 of rise core pipe 1 and 1 other end of core pipe that rises.
Its not only good positioning effect, and do not hurt pipe fitting inner wall, it is durable;Being tested the core that rises can Reusability 20000 More than secondary.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry it should be appreciated that the present utility model is not limited to the above embodiments, do not depart from the spirit of the present invention and Under the premise of range, the utility model also has various changes and improvements, these changes and improvements both fall within claimed Within the scope of utility model.The protection scope of the present invention is defined by the appended claims and their equivalents.
