Abstract
The invention discloses an integral zigzag slip for a pipeline and belongs to the technical field of connecting devices. Clamping teeth embedded into the outer wall of the pipeline are arranged on the inner wall of the slip, and after the clamping teeth are embedded with the outer wall of the pipeline, acting force limiting relative motion of the clamping teeth and the outer wall of the pipeline can be produced between the clamping teeth and the outer wall of the pipeline, and accordingly relative motion between the slip and the outer wall of the pipeline is prevented. Due to the fact that after the outer wall of a slip body is connected with the inner wall of a sealing mechanism, relative sliding is not produced between the body and the sealing mechanism, and the relative motion between the slip and the inner wall of the pipeline can be prevented. When the relative motion is not produced between the slip and the outer wall of the pipeline and relative motion is not produced between the slip and the inner wall of the pipeline, no relative motion is produced between the inner wall of the sealing mechanism and the outer wall of the pipeline. Therefore, the slip can prevent rotation and horizontal translation of the external sealing mechanism with the pipeline axis as the rotation center.

Embodiment
In order to understand the present invention in depth, below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
See accompanying drawing 1, the overall back-shaped slips of pipeline provided by the invention comprises body 1, the radial cross section of body 1 is arc, the diameter of arc equals the diameter of pipeline, body 1 inwall is provided with the latch 2 for embedding pipeline outer wall, after the outer wall of body 1 is connected with the inwall of sealing mechanism, without relative sliding between body 1 and sealing mechanism.
The pipeline provided by the invention latch 2 that overall back-shaped slips is provided with by its inwall is embedded in pipeline outer wall, after this latch 2 is chimeric with pipeline outer wall, the active force restricting its relative movement can be produced between latch 2 and pipeline outer wall, thus stop the relative movement between this slips and pipeline outer wall; After pipeline provided by the invention is connected with the inwall of sealing mechanism with the overall back-shaped outer wall of slips body 1, without relative sliding between body 1 and sealing mechanism, therefore, it is possible to stop the relative movement between this slips and sealing mechanism inwall.Without relative movement between this slips and pipeline outer wall, and, time between this slips and inwall of sealing mechanism without relative movement, relative movement is not had between sealing mechanism inwall and pipeline outer wall yet, therefore, this slips can stop external sealing mechanism with pipeline outer wall be rotating center rotate or along the translation of pipeline axial left and right.
Wherein, as this pipeline the first concrete implementation with overall back-shaped slips, the overall back-shaped slips of pipeline provided by the invention can also comprise key, and the outer wall of body 1 and the inwall of sealing mechanism are equipped with keyway, and body 1 outer wall is connected by key with sealing mechanism.Due to the connection between this body 1 outer wall and sealing mechanism inwall and the connection between wheel and wheel hub similar, therefore, can by wheel with wheel hub between Placement and key connect realize connect this body 1 outer wall and sealing mechanism inwall and reach the effect of transmitting torque between sealing mechanism inwall and body 1 outer wall, thus make this pipeline with between overall back-shaped slips and pipeline outer wall without relative movement.
Wherein, as this pipeline concrete implementation of the second of overall back-shaped slips, body 1 outer wall is provided with teeth 3, and the inwall of sealing mechanism is provided with teeth groove, and teeth 3 are suitable with teeth groove, and body 1 outer wall is connected by teeth 3 and teeth groove with sealing mechanism.Because teeth 3 are protruding structures, teeth groove can be suitable with teeth, when after teeth 3 with tooth socket fit, produce mutual active force because of mutually supporting between the boss of teeth 3 and the depressed area of teeth groove and reach the effect of transmitting torque between sealing mechanism inwall and body 1 outer wall, thus make this pipeline with between overall back-shaped slips and pipeline outer wall without relative movement.
Wherein, teeth 3 are stepped in the outer wall circumference of body 1, and teeth groove is also stepped.Due to pipeline provided by the invention, with overall back-shaped slips, when applying, it is embedded in groove that sealing mechanism inwall is provided with, in order to the groove fit that this body 1 and sealing mechanism inwall can be made to be provided with is tightr, this body 1 needs to produce mutually moving along pipeline axial usually between sealing mechanism inwall, and teeth 3 are stepped in the outer wall circumference of body 1, teeth groove is also stepped when arranging, and can be providing convenience along mutually moving of pipeline axial of producing between body 1 and sealing mechanism inwall.
See accompanying drawing 2 and accompanying drawing 3, the angle of latch 2 is 90 °, and the angle of the rake angle α of latch 2 is 60 °, and the angle of the angle of back of tooth β of latch 2 is 30 °.Arranged by such angle, after body 1 inwall and pipeline outer wall are mutually chimeric, latch 2 can and pipeline outer wall between produce interaction force and transmitting torque, stop the relative movement of this pipeline between overall back-shaped slips and pipeline outer wall.
Wherein, body 1 offers elongate slot 4 vertically, this elongate slot 4 can reserve space for this body 1 in the elastic strain of circumference, when the groove fit that this body 1 and sealing mechanism inwall are provided with is tending towards tight, be unlikely to reach best cooperation position due to the restriction of body 1 girth.
Wherein, elongate slot 4 is several, the opening direction of two adjacent elongate slots 4 is contrary, if the opening direction of all elongate slots 4 all in the same way, so when body 1 is when the elastic strain of circumference is larger, the unfolded drawing of this body 1 will trend towards becoming an eccentric circular ring, at the opening direction of this elongate slot 4, its diameter is less than the diameter in this not opening direction of elongate slot 4, thus causes pipeline itself to produce distortion; And if when the opening direction of adjacent two elongate slots 4 is contrary, even if body 1 is when the elastic strain of circumference is larger, the unfolded drawing of this body 1 is still a rectangle, now, the uniform diameter in axis of this body 1, and pipeline itself can not be caused to produce distortion.
Wherein, the number of degrees of the central angle that arc is corresponding are 180 °, in such a situa-tion, only need the overall back-shaped slips of two pipelines provided by the invention can form a complete annulus, when this pipeline coordinates with sealing mechanism with overall back-shaped slips, can the overall back-shaped slips of these two pipelines be assembled in the two half-unit of sealing mechanism respectively, then by sealing mechanism two half-unit to being combined, if the overall back-shaped slips of pipeline provided by the invention is made a complete entirety, then need from one end of pipeline sheathed, and in practice, the setting of pipeline is often intricate, be difficult to find end, even if or its end known, its end also may outside tens kilometers even several thousand kilometers, several ten thousand kilometers, in this case, to complete the overall back-shaped slips of this pipeline with coordinating of pipeline be impossible by sheathed, if the central angle that this arc is corresponding is less than 180 °, it also must be the angle that can be divided exactly by 360 °, such as, it can be 120 °, 90 ° etc., if and the central angle of the correspondence of this arc is 120 °, then the overall back-shaped slips of 3 these pipelines is needed to coordinate when assembling, if the central angle that this arc is corresponding is 90 °, then the overall back-shaped slips of 4 these pipelines is needed to coordinate when assembling, if the number of degrees of the central angle that this arc is corresponding reduce further, this pipeline then needed when assembling will increase further by the number of overall back-shaped slips, no matter this pipeline is needs 3 with overall back-shaped slips, 4 still more, it is not too easy that capital causes when being assembled to pipeline and sealing mechanism, and, because this pipeline is needs 3 with overall back-shaped slips, 4 or more time, these 3, 4 or more pipeline will be more at the interface of circumference with overall back-shaped slips, the situation that sealability is bad is easily there is at this jointing, thus affect the overall sealing performance of the overall back-shaped slips of this pipeline after assembling with pipeline and sealing mechanism.
Wherein, latch 2 is arranged along the circumference of pipeline, and the effect due to this latch 2 is chimeric with pipeline outer wall, when latch 2 is arranged along pipeline circumference, is equivalent to outwards be fitted together to layer by layer from pipe leakage.
In addition, reach maximum to make the interaction force between teeth 3 and teeth groove, thus stop the relative movement between teeth 3 and teeth groove to greatest extent, fitting surface between teeth 3 and teeth groove is preferably designed at pipeline radial, in this case, the interaction force produced between teeth 3 and teeth groove does not have the component in other directions, makes the anti-rotation better effects if of pipeline provided by the invention between overall back-shaped slips and sealing mechanism.For the ease of the active force applying along pipeline axial with overall back-shaped slips to this pipeline, teeth 3 can be set to several, the upper plane parallel of these several teeth 3.
In order to can processing request be met, and, make to be unlikely to the pipeline that frays when this pipeline overall back-shaped slips and tube fit, the crown 5 of latch 2 can be done the process of 0.1mm ~ 0.2mm fillet; The tooth root 6 of latch 2 is done the process of 0.1mm ~ 0.2mm fillet simultaneously.
The tooth depth h of latch 3 then can determine according to parameters such as different outer diameter tube and wall thickness, thus makes pipeline provided by the invention stronger from the adaptability of different pipeline with overall back-shaped slips.
Above-described embodiment; object of the present invention, technological scheme and beneficial effect are further described; be understood that; the foregoing is only the specific embodiment of the present invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
