Description
Technical field
The present invention relates to a kind of stable shape seal for pipe joints joint, belong to pipeline connection mechanism field.
Background technology
Pipeline is connected to bindiny mechanism of some equipment either on intermediate connector by pipe joint as a kind of, and it connects
After connecing, the requirement to sealing property is higher, in order to adapt to the pipeline that some needs are often dismantled, also there is a kind of pipeline of fast-connecting type
Joint, it mainly by a hold-down ring, the rubber ring of annular is extruded by hold-down ring, is realized using the crimp of rubber ring
Sealing between pipeline and joint, but in order to ensure good sealing property, it is necessary to the deflection of rubber ring is larger, excessive
Extruding is easy to allow rubber ring to be broken, and is easy to so that rubber ring inwall is damaged, have a strong impact on pipeline when pipeline inserts
Sealing effectiveness.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the quick connector stability of the deformation connection of cushion rubber in the prior art compared with
A kind of technical problem of difference, there is provided stable shape seal for pipe joints joint.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of stable shape seal for pipe joints joint, including main contiguous block, the inside of the main contiguous block are coaxially arranged with a connection
Hole, a sealing collar is fixed with inside the connecting hole, and axial one end of the sealing collar is fixed with the company of extending into
The seal rubber sleeve inside hole is connect, pushing tow gap is provided between seal rubber sleeve and connecting hole inwall；Also set up in the connecting hole
There is seal rubber sleeve top-pushing mechanism, the seal rubber sleeve top-pushing mechanism includes a pushing tow ring and a drive ring；Wherein described top
Be slidably connected between throw-out collar and connecting hole inwall, the inwall of the pushing tow ring is divergent structure, its flared end towards seal rubber sleeve,
And the wall thickness of the flared end of pushing tow ring is less than pushing tow gap, to be fixedly connected between the drive ring and connecting hole inwall, pass through
The driving of drive ring causes pushing tow ring to be pushed into pushing tow gap；On one end outer wall of the direction sealing collar of the main contiguous block
A bracing ring is also associated with, an inner-walls of duct connecting cylinder, the inner-walls of duct connection are provided with the middle part of the bracing ring
Some positioning convex are provided with the outer wall of cylinder；The outer wall of the main contiguous block is provided with a step ring, the step ring
Connection screw thread is coaxially arranged with outer wall.
As a further improvement on the present invention, the company of being threadably secured between the outer wall of the outer ring of bracing ring and main contiguous block
Connect, the bottom wall annular array of the bracing ring is provided with some positioning holes, annular on the end wall of the main contiguous block
Array is provided with some positioning convex for being used to be embedded into positioning hole.
As a further improvement on the present invention, it is connected through a screw thread between the drive ring and connecting hole.
As a further improvement on the present invention, the positioning convex is embedded into convex in inner-walls of duct connecting cylinder including one
Playing piece.
As a further improvement on the present invention, the inwall of the seal rubber sleeve is divergent structure, and the internal diameter of its flared end is small
In the internal diameter of sealing collar, the flared end of seal rubber sleeve is towards seal rubber sleeve top-pushing mechanism.
The beneficial effects of the invention are as follows：
1st, the present invention replaces original O-ring seal by a seal rubber sleeve, and the elasticity of the seal rubber sleeve utilized in itself utilizes one
Seal rubber sleeve is socketed on pipe to be connected by individual pushing tow ring, bigger compared to sealing ring contact area, and is not easy to seal
Damaged or fracture is less likely to occur compared to O-ring seal for gum cover, and during pipe insertion, the concentrated wear to inwall also will not
Sealing of the whole section of seal rubber sleeve to tubing is had influence on, effect is more preferable.
2nd, bracing ring is connected through a screw thread, can be changed according to the tubing of different wall different inner-walls of duct connecting cylinder and
Seal rubber sleeve, it is simple and convenient, when the positioning convex of setting can prevent that pipeline from connecting, because whole caused by the revolving force of pushing tow ring
Body threaded connector releases.
3rd, positioning convex can be realized to inner-walls of duct and fixed, and during preventing connection, pipeline retinue rotates, and causes close
Bind the releasing of circle.
4th, the seal rubber sleeve of divergent structure improves the thickness of end, while seal rubber sleeve variable amplitude is ensured, carries
The high effect of sealing.
