Abstract
A pipe jointer comprises two expansion rings, two screws, a connection rod and a support ring, and is less in materials used, easy to product, simple in assembly and disassembly and accurate in connection.
Description
Technical field
The utility model relates to a kind of pipe connector, particularly to adopt screw to cause the pipe connector of tension force.
Background technique
Existing pipe connector generally is to have the connecting rod of conical screw and fluting tapered cup nut to constitute by two.The fluting tapered cup nut rotates on conical screw when its diameter is increased and produces tension force, for example: CN2265451Y, CN 2370201Y, CN 2440966Y.The conical screw materials are more.The screw rod of taper and nut are difficult to be made, and generally uses mould-forming, can stay assembly line on the cone screw face of screw rod, during rotation easily and the notch on the tapered cup nut interfere, mounting or dismounting make things convenient for inadequately.The mould of making tapered cup nut is also complicated.And when tapered cup nut notch quantity was 1, connected pipe and pipe connector decentraction connected accurate inadequately.
Summary of the invention
The utility model pipe connector, its goal of the invention are for less, the easy manufacturing of a kind of materials, mounting or dismounting convenience being provided and being connected pipe connector accurately.
For reaching above-mentioned purpose, the utility model adopts following technological scheme, and it is made of two packings, two screws, a connecting rod and a supporting ring.Screw head places the endoporus of packing, and the screw rod of screw partly is screwed in the nut of connecting rod end, when the packing inner headed face slides on the frustum of connecting rod end, and the periphery diameter even variation of packing, the swelling or the connected pipe that gets loose with one heart.
The hole identical with the shape of the screw head that is adopted is set in the packing.
The packing endoporus is provided with convex tendon.
Be provided with on the packing along the equally distributed notch of circumference.
The end of connecting rod is provided with frustum and nut.
The utility model has the advantages that materials are less, make easily that mounting or dismounting are convenient, connect precisely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a part section tectonic maps of the present utility model, shows a kind of embodiment of this pipe connector.
Fig. 2 is the longitudinal section tectonic maps and the left view of packing of the present utility model and bolt structure, and the nature that packing in this pipe connector is not filled in the connected tube period of the day from 11 p.m. to 1 a.m is shown.

Embodiment
As seen from Figure 1, the two ends of connecting rod 2 are shaped on frustum 5 and nut 6.The screw head 10 of screw 4 places the endoporus 12 of packing 1, and the screw rod 9 of screw 4 is screwed in the nut 6 of connecting rod 2 ends, and supporting ring 3 places the middle part of connecting rod 2.Supporting ring 3 supportings two velamens connect the pipe end of pipe.Convex tendon 11 restriction screw head 10 in packing 1 endoporus 12 are freely deviate from from the endoporus 12 of packing 1.Connected pipe drives screw 4 rotations when driving packing 1 rotation, make packing 1 along connecting rod 2 axial motions during screw 4 rotations, inner headed face 7 spirality on the frustum 5 of connecting rod 2 of packing 1 is slided, thereby each produces being connected and separating of the concentric swelling and the action that gets loose, realization pipe to even variation on circumference to make the diameter of periphery 8 of packing 1 of notch 13.
