Description
Technical field
The utility model relates to a kind of sound detecting pipe left hand screw joint, belongs to assembling pipe joint.
Background technique
Sound detecting pipe is the requisite sonic detecting tube of present bridge construction, utilizes sound detecting pipe can detect the quality of a pile, sound detecting pipe be bored concrete pile when carrying out ultrasound detection probe enter the passage of pile body inside.When mounted, some sound detecting pipes are embedded in stake, need between some sound detecting pipes to be spliced by piecing devices, prior art adopts thread type joint style to connect, the screw thread of thread type joint on it is tiny and many, joint easily collides with damage in carrying, cause waste, and due to screw thread tiny and many, installation is wasted time and energy, joint fastness does not reach excellent effect, and inside, joint adopts cross section to be columniform seal ring, poor with joint sidewall laminating degree, cause poor air-tightness, if sound detecting pipe material or mounting process poor time, spillage may be caused, plugging, fracture, bending, sink, the generation of the accidents such as distortion, pile's integrity testing is carried out to Method of Ultrasonic Penetration and produces considerable influence, Method of Ultrasonic Penetration detection cannot be carried out even.
Summary of the invention
For solving the problem, the purpose of this utility model is a kind of sound detecting pipe left hand screw joint, its have left-handed thread space greatly, not easy to wear, install simple and easy, time saving and energy saving, good, the fastness of docking property by force, the advantage that not fragile, sealing is good.
For achieving the above object, the technical solution of the utility model is: a kind of sound detecting pipe left hand screw joint, the sub-set pipe comprising mother set pipe and cooperatively interact with it, the outer wall of described sub-set pipe assembling end is provided with outer left hand thread, sub-set pipe holds relative the other end inwall to be provided with first sound test tube joint with assembling, left hand thread in the inwall of described mother set pipe assembling end is provided with and matches with outer left hand thread, interior left hand thread end is provided with baffle ring, mother set inner tube wall outside baffle ring is provided with second sound test tube joint, the seal ring fitted tightly with it is also provided with inside baffle ring, described sub-set pipe is spirally connected with matching of interior left hand thread by outer left hand thread with mother set pipe, described seal ring is used for sealing the gap formed between baffle ring and sub-set tube end.Left-handed thread lines is comparatively large, and docking is fast, installs simple and easy, save trouble and labor, and fastness is stronger, and first sound test tube joint and second sound test tube joint are socketed sound detecting pipe close and firm more.
As preferably, after described sub-set pipe and mother set pipe are connected, its joint is annular groove.
As preferably, the cross section of described seal ring is right-angled trapezium.High with baffle ring laminating degree, trapezoidal faces matches with sub-sleeve bottom and contacts, and improves sealing.
As preferably, the external diameter of the sub-set pipe outside described annular groove is equal with the external diameter of mother set pipe.
As preferably, described baffle ring radial thickness is equal with seal ring radial thickness.
As preferably, the length of described outer left hand thread is 2/3rds of sub-set length of tube.
As preferably, the cross section of described first sound test tube joint and second sound test tube joint is annular.
The beneficial effects of the utility model: left-handed thread space greatly, not easy to wear, install simple and easy, time saving and energy saving, good, the fastness of docking property by force, not fragile, sealing is good.
