Abstract
The utility model relates to a tool in the technical field of manufacturing of plastic pipes, and particularly discloses an orifice expander for a plastic pipe. The orifice expander comprises a support frame, wherein the support frame is formed by connecting two barrel-shaped structures by virtue of connecting pieces; the two barrel-shaped structures are a first barrel positioned outside the plastic pipe and a second barrel positioned in the plastic pipe during expansion respectively; a plurality of expansion elements are arranged in gaps of the connecting pieces between the two barrel-shaped structures; a section of a convex ring along a circular arc is arranged outside each expansion element, guide rod connecting structures are arranged on the inner sides of the expansion elements, and a guide rod is connected to the inner sides of the expansion elements; guide rod connecting expansion elements are screws with tapered structures; the guide rod is provided with a handle which is positioned outside the first barrel; the front end part of the second barrel is of a circular truncated cone-shaped structure. The orifice expander for the plastic pipe has the advantages of simplicity in operation and good forming effect.
Description
Technical field
The utility model relates to the frock tool in plastic tube manufacturing technology field, particularly plastic tube pipe flaring tool.
Background technology
Plastic tube comprises plastic tube body, while installing and using, many plastic tubes need to be coupled together to use, in order to connect more easily, it is large that plastic tube is made an end opening, the structure that one end opening is little, the end that the end that opening is large and opening are little matches, so also have Seepage, in order further to reduce seepage, in the large inner side, one end of opening, be also designed with the loop configuration of protrusion, the inner rubber ring of placing of loop configuration protruding during installation, make antiseep better effects if, in prior art, the loop configuration of making this protrusion is to use easy expansion tool, such instrument has troublesome poeration, the irregular shortcoming of annular.
Summary of the invention
The purpose of this utility model will overcome above-mentioned shortcoming exactly, and a kind of plastic tube pipe flaring tool of simple to operate, good forming effect is provided.
The technical solution of the utility model is achieved in that a kind of plastic tube pipe flaring tool, it is characterized in that: it comprises bracing frame, bracing frame is that two tubular constructions link together with connector, the first cylindrical shell when two tubular constructions are respectively expansion outside plastic tube and the second cylindrical shell inside plastic tube, in the gap of the connector in the middle of two tubular constructions, there are a plurality of expansion parts, the outside of expansion part is that convex hole is along one section of circular arc, it is the structure that a plurality of expansion parts can surround convex hole, there is the structure of connection guide rod the inside of expansion part is connected with guide rod, it is the screw of pyramidal structure that guide rod connects expansion part, guide rod has handle in the first cylindrical shell outside.
Further say, the second described barrel front end portion is the structure of truncated cone-shaped.
The beneficial effects of the utility model: such plastic tube pipe flaring tool has advantages of simple to operate, good forming effect.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Wherein: 1, connector 2, the first cylindrical shell 3, the second cylindrical shell 4, expansion part 5, guide rod 6, handle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in 2, a kind of plastic tube pipe flaring tool, it is characterized in that: it comprises bracing frame, bracing frame is that two tubular constructions link together with connector 1, the first cylindrical shell 2 when two tubular constructions are respectively expansion outside plastic tube and the second cylindrical shell 3 inside plastic tube, in the gap of the connector in the middle of two tubular constructions, there are a plurality of expansion parts 4, the outside of expansion part 4 is that convex hole is along one section of circular arc, there is the structure of connection guide rod the inside of expansion part is connected with guide rod 5, it is the screw of pyramidal structure that guide rod connects expansion part, guide rod has handle 6 in the first cylindrical shell outside.
Like this, operating grip, guide rod will advance, and because guide rod connects expansion part, is the screw of pyramidal structure, and expansion part will stretch out, and makes the inside of plastic tubes being heated form the circular ring structure protruding; Reverse operating, expansion part will be retracted, and can take out this expander.
Further say, the second described barrel front end portion is the structure of truncated cone-shaped.
More convenient like this plastic tube pipe flaring tool is placed on inside of plastic tubes.
Claims (2)
1. a plastic tube pipe flaring tool, it is characterized in that: it comprises bracing frame, bracing frame is that two tubular constructions link together with connector, the first cylindrical shell when two tubular constructions are respectively expansion outside plastic tube and the second cylindrical shell inside plastic tube, in the gap of the connector in the middle of two tubular constructions, there are a plurality of expansion parts, the outside of expansion part is that convex hole is along one section of circular arc, there is the structure of connection guide rod the inside of expansion part is connected with guide rod, it is the screw of pyramidal structure that guide rod connects expansion part, and guide rod has handle in the first cylindrical shell outside.
2. plastic tube pipe flaring tool according to claim 1, is characterized in that: the second described barrel front end portion is the structure of truncated cone-shaped.
