Abstract

The utility model discloses a threaded-connection structure of a sounding pipe, comprising two sections of pipe bodies, wherein the two pipe bodies are connected together by a joint; the joint comprises a connecting pipe, two nuts with internal threads and two O-shaped sealing rings; the two ends of the connecting pipe are provided with external threads; the two nuts are matched with the two ends of the connecting pipe; the inner diameter of the connecting pipe is larger than that of each pipe body, and the two ends of the inner walls of the connecting pipe are flared conical surfaces; the thread end of the inner wall of each nut is a closed conical surface; the inner walls of the O-shaped sealing rings are in interference fit with the pipe bodies, and the outer walls of the O-shaped sealing rings are arc-shaped along the axial direction; and in connection, the flared conical surfaces of the end parts of the connecting pipe and the closed conical surfaces in the nuts are closely attached with the outer walls of the O-shaped sealing rings. The threaded-connection structure has the advantages of simple structure, good sealing effect and convenience in installation.

Description

The sound detecting pipe screw connection structure
Technical field
The utility model relates to the building pipe field, relates in particular to a kind of sound detecting pipe screw connection structure.
Background technique
In the work progress of construction engineering; The normal integrity that adopts supersonic sounding to check pile foundation; Supersonic sounding needs before the concrete spouting of pile foundation, in advance sound detecting pipe to be fixed on the cage, then penetration concrete; Thereafter again through emission between sound detecting pipe and reception sound wave, the parameters,acoustic that reflects with sound wave changes the purpose that reaches the inspection pile body integrity.
At present, sound detecting pipe is according to unusual be threaded sound detecting pipe and the plug-type sound detecting pipe that is connected of being divided into of Placement.The sound detecting pipe that is threaded is generally unidirectional connection, need be with externally threaded joint in the end welding one of sound detecting pipe during use, makes it to form fixed end; The other end is a movable end, utilizes tapped nut fitted seal circle (being generally O type circle) to link to each other with joint during use, thereby two sections sound detecting pipes are linked together; But the sound detecting pipe sealing effect that connects like this is not good, and connects very inconvenient.Plug-type connection sound detecting pipe then is to be utilized in a plurality of seal rings are set in the body, an end of a body is inserted in another root body seal ring, thereby accomplishes interfixing of many sound detecting pipes; This sound detecting pipe is installed difficulty more, and sealing effect is also bad.
The model utility content
To the above-mentioned deficiency that existing technology exists, the purpose of the utility model just is to provide a kind of sound detecting pipe screw connection structure, and good sealing effect is easy for installation.
To achieve these goals; The technological scheme that the utility model adopts is such: a kind of sound detecting pipe screw connection structure; Comprise two sections bodys; Two bodys are connected together through a joint, and said joint comprises the externally threaded connecting tube of a two ends band, two tapped nuts that cooperate with the connecting tube two ends and two O RunddichtringOs; The internal diameter of said connecting tube is greater than the internal diameter of body, and its inwall two ends are the conical surface of enlarging; The conical surface of the screw thread end place of said nut inner wall for closing up; The inwall of said O RunddichtringO and body interference fit, its outer wall is the arc arc vertically; During connection, the inner closing in conical surface and the O RunddichtringO outer wall of the enlarging conical surface of connecting tube end and nut fits tightly.
Nut is with after connecting tube is connected; In nut, form a curve bath naturally, during connection, earlier two nuts are inserted in the end that two sections bodys need link to each other respectively; Be inserted in the O RunddichtringO then, cooperate with nut, O RunddichtringO through connecting tube again two sections bodys are connected together.Like this in connection procedure, two nuts can independent rotation, forms two-way connection, makes easier for installation.
Further, the outer wall semicircular in shape of said O RunddichtringO.
Further, has separation line in the middle part of the said connecting tube outer wall.
Further, has groove on the said separation line.
Compared with prior art, the advantage of the utility model is: realize two-way connection through this joint, and easier for installation; Not be used in welded joint etc. on the sound detecting pipe, process simpler; Female with after connecting tube is connected, curve bath of formation naturally in nut can compress the O RunddichtringO better, and the while sealing effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
Embodiment: referring to Fig. 1; A kind of sound detecting pipe screw connection structure; Comprise that two sections body 1, two bodys are connected together through a joint, said joint comprises the externally threaded connecting tube of a two ends band 2, two tapped nuts 3 that cooperate with the connecting tube two ends and two O RunddichtringOs 4; The internal diameter of said connecting tube is greater than the internal diameter of body, and its inwall two ends are the conical surface of enlarging; The conical surface of the screw thread end place of said nut inner wall for closing up; The inwall of said O RunddichtringO and body interference fit, its outer wall is the arc arc vertically; During connection, the inner closing in conical surface and the O RunddichtringO outer wall of the enlarging conical surface of connecting tube end and nut fits tightly.
Nut is with after connecting tube is connected; In nut, form a curve bath naturally, during connection, earlier two nuts are inserted in the end that two sections bodys need link to each other respectively; Be inserted in the O RunddichtringO then, cooperate with nut, O RunddichtringO through connecting tube again two sections bodys are connected together.Like this in connection procedure, two nuts can independent rotation, forms two-way connection, makes easier for installation.
The outer wall semicircular in shape of said O RunddichtringO; Easy processing, and more reasonable structure.
Said connecting tube outer wall middle part has separation line 5; Has groove 6 on the said separation line.Economical with materials more.
The utility model is simple in structure, realizes two-way connection through this joint, and is easier for installation; Not be used in welded joint etc. on the sound detecting pipe, process simpler; Female with after connecting tube is connected, curve bath of formation naturally in nut can compress the O RunddichtringO better, and the while sealing effect is better.
Need to prove at last; Above embodiment is only in order to technological scheme but not the restriction technologies scheme of explanation the utility model; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
