Abstract

The utility model discloses a pipe joint which is very suitable for the connection of water pipes. The pipe joint can solve the technical problem that the pipe joint doesn't adopt a screwed connection on a connected pipe. The pipe joint expands the water pipe to closely seal. The pipe joint comprises a nut, a pipe fitting and a sealing element, the pipe joint is characterized in that the pipe joint also comprises a cone connecting element (1), a compact element (3) and a fastener (2), and the compact element (3) has a conical bore (6) or a circular hole to match a pyramid (5) of the cone connecting element (1). The fastener is sheathed on the compact element (3), one end of the fastener is provided with a screw to connect the screw of the cone connecting element, and the connected pipe (4) can be inserted into an interstice of an inner hole and the compact element. When the fastener moves toward the big end of the pyramid, the compact element also moves to the big end of the pyramid at the same time, so the compact element is expended to make the connected pipe attach to the inner wall of the fastener.

Description

Pipe joint
Skill is stated the field:
Pipe joint belongs to Pipe joint, is applicable to the connection of water pipe especially.
The background skill is stated:
Present pipe joint all will machining screw, usefulness nut, pipe fitting, Sealing connection then on connecting tube.So when adapter was refuted in maintenance, particularly field construction needed to be equipped with machining screw cutter and other instrument.These instruments weigh greatly, increase transportation difficulty and construction.And connection mouth easily leaks, and need do over again, and influences repair quality.
Summary of the invention:
Pipe joint will solve and not adopt the skill that is threaded to state problem on connected tube.
Pipe joint adopts the way of the pipe account being forced tightening seal greatly.
Pipe joint contains nut, pipe fitting, Sealing, its feature is forced tight part, cone link and fastening piece, force tight part to have taper hole or circular hole to cooperate with the cone of cone link, fastening piece is enclosed within forces on the tight part, fastening piece one end has being threaded of screw thread and cone link, its endoporus and force gap between the tight part can be put connected tube into.When fastening piece when the big end of cone moves, simultaneously forcing tight part also to move to the big end of cone, so, force tight part to be swollen, make connected tube force tightly inwall at fastening piece.
The tight part of forcing of the utility model pipe joint has the bloated performance of Peng, connected tube is forced tightly forcing between tight part and the fastening piece, forces tight part can adopt plastics or rubber material manufacturing.Because without scyewed joint, so, can be used for the connection of light wall pipe.
Description of drawings:
Fig. 1 is the pipe joint erection drawing.
Fig. 2 is a cone link sectional view.
Fig. 3 forces tight part sectional view.
1, cone link 2, fastening piece 3, force tight part 4 connected tubes 5, external cone 6, internal taper hole
Specifically execute mode:
Scheme with specific embodiment explanation pipe joint.
The structure of Fig. 1 display tube joint, it by cone link 1, fastening piece 2, force tight part 3 to form.Force tight part to adopt the plastic materials manufacturing, because plastics have certain plasticity and elasticity.Force tight part 3 to have internal taper hole 6 to cooperate (Fig. 2,3) with the external cone 5 of cone link.Fastening piece and cone link when turn Fastener 2, move right it with being threaded, and then force tight part also to be forced to move right, and simultaneously, external cone 5 outwards swells internal taper hole 6, make to force tight part Peng to expand, and connected tube 4 is pressed hard at the fastening piece inner hole wall.

Claims (2)

1, pipe joint contains nut, pipe fitting, Sealing, it is characterized in that having cone link (1), force tight part (3) and fastening piece (2), force tight part to have taper hole (6) or circular hole to cooperate with the cone (5) of cone link, fastening piece is enclosed within forces on the tight part, fastening piece one end has being threaded of screw thread and cone link, its endoporus and force gap between the tight part can be put connected tube (4) into; When fastening piece when the big end of cone moves, simultaneously forcing tight part also to move,, make connected tube force tightly inwall at fastening piece so force tight part to be swollen to the big end of cone.
2, pipe joint according to claim 1 is characterized in that the described tight part (3) of forcing adopts plastics or rubber material manufacturing.
