In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
See accompanying drawing 1, the overall back-shaped slips of the pipeline that the utility model provides 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 that the utility model the provides 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 the pipeline provided due to the utility model 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 the pipeline that the utility model provides 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.When applying, to the overall back-shaped slips of pipeline provided due to the utility model it be 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, the overall back-shaped slips of pipeline only needing two the utility model to provide 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 the pipeline provided by the utility model makes 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.
