The present invention relates to a kind of cover, this cover is for wrapping at least one elongated member of such as pipe or cable.In addition, the present invention relates to a kind of assembly comprising at least one elongated member and this cover.In addition, the present invention relates to a kind of assembling method be assembled in by this cover at least one elongated member.
The present invention is applied to the field for the pipe of motor vehicle or the cover of cable.Motor vehicle especially refer to the industrial car of touring car, transport vehicle or such as truck type.
Background technique
FR2911945A1 describes a kind of cover for wrapping the pipe in motor vehicle.Cover in FR2911945A1 comprises tubular wall, and this tubular wall has outer surface and internal surface, and internal surface is defined for the passage of pipe.In addition, the cover in FR2911945A1 comprises contact segment, and contact segment extends on the relative sidepiece of internal surface, so that along Brake pipe during pipe translation.When the cover in FR2911945A1 be assembled in pipe upper time, operator by the enclosure on pipe.In order to allow this assembling, the cover in FR2911945A1 is very flexible, so that distortion is for being enclosed within pipe fully.
But cover of the prior art has invalid translation braking or the inconvenient assembling of tool.Therefore, very resilient cover can not realize the effective translation braking along pipe.Therefore, this extra arrestment mechanism needing such as tackiness agent when being covered with, to avoid cover to move along pipe.
On the contrary, some cover of the prior art disturbs pipe consumingly, and such as, when cover relative rigidity, this allows effectively and stops translation enduringly.But the cover of rigidity has friction and the danger of scraping pipe, this its assembling on pipe of obviously slowing down, produces the bits of cover and/or pipe and on pipe, leaves the ugly marking.In addition, the friction covered on pipe also has the danger removing the information be labeled on pipe.
When all, cover of the prior art does not allow to find compromise between the simplification and the validity of translation braking of assembling, the simplification of assembling needs the weak jamming between cover and pipe, and the validity of translation braking needs the strong jamming between cover and pipe on the contrary.
Summary of the invention
Object of the present invention solves above-mentioned problem whole or in part especially by providing a kind of cover, and this cover can quick mounting and do not swipe and mark, and ensures effectively and the translation braking continued simultaneously, and locates very accurately.
For this reason, the object of this invention is to provide a kind of cover, described cover is for wrapping at least one elongated member of such as pipe or cable, and described cover at least comprises:
-tubular wall, it has outer surface and internal surface, and described internal surface limits passage, described passage for receiving at least one elongated member described, and
-the first contact segment and the second contact segment, described first contact segment extends on the relative sidepiece of described internal surface with described second contact segment,
The feature of described cover is, described tubular wall is elastically deformable between following two configurations at least:
-assembled configuration, in this assembled configuration, described tubular wall is out of shape by the pressing force be applied in roughly relative direction on described outer surface, to make described first contact segment and described second contact segment separately, at least one elongated member described can be inserted in described passage
-clamping configuration, in this clamping configuration, when lacking described pressing force, compared with assembled configuration, described first contact segment and described second contact segment are separated smaller, make when at least one elongated member described is inserted in described passage, clamping force can be passed at least one elongated member described by described first contact segment and described second contact segment.
Therefore, this cover can be arranged on any elongated member fast and simply, and not to elongated member scraping or mark.Meanwhile, because the first and second contact segments can provide disturb surface with the large of elongated member, so this cover ensures to cover on along the effective brake in the translation of elongated member.In addition, because the operation of cover is very simple, so cover can accurately be placed on elongated member by operator.Pressing force uses instrument by operator or does not such as manually use instrument and apply.
Because lack pressing force, compared with assembled configuration, tubular wall is out of shape less in clamping configuration.Compared with assembled configuration, the first and second contact segments are separately less in clamping configuration.
In this application, term " tubulose " especially refers to the wall limiting closed profile line in the planes; This profile line closed can have such as any shape such as circle, ellipse, rectangular, square.
In this application, term " roughly relative direction " especially two pressing forces, the respective direction of two pressing forces forms the angle being greater than 135 degree between its vector.Such as, when cover comprises (the first and second) two contact segments, pressing force can be strictly relative, between its vector, namely form the angle of about 180 degree.According to another example, when cover comprises (the first, the second and the three) three contact segments, pressing force can roughly relatively and between its vector, form the angle of about 120 degree between two; The vector of bearing capacity converges along leg-of-mutton three center lines, and this vertex of a triangle is roughly corresponding with by operator presses press points on the outer surface.
Compared with clamping configuration, described in assembled configuration, the first contact segment is separated larger with described second contact segment.In other words, if consider span measured between and second point at first that belongs to the first contact segment and the second contact segment respectively, compared with clamping configuration, in assembled configuration, this span is larger.
According to an embodiment of the invention, described outer surface has two area presseds, and described two area presseds are arranged to and apply described pressing force, and described area pressed is roughly relative, and each area pressed is roughly between two relative sidepieces.
Therefore, these two area presseds allow operator to apply pressing force on the outer surface.
According to a modified example of the present invention, described outer surface has the mark of the position of instruction area pressed.Therefore, operator can find area pressed rapidly.Substituting or supplementing as aforementioned variant example, the side (tranche) of cover has the mark of the position of instruction area pressed on side.Such as, mark can be formed by visual mark (arrow of instruction area pressed) or by being positioned on outer surface or the mark (the upper roughness on each area pressed) touched be positioned on the side of cover is formed.
Advantageously, each area pressed is positioned at zone line place, and zone line is positioned at the distance equal with the second contact segment with the first contact segment.In other words, on the outer surface toward each other, this permission applies pressing force to area pressed in relative direction.
According to an embodiment of the invention,
The ratio of the-the first distance and second distance is between 1 and 2, preferably between 1.1 and 1.7, between described area pressed, measure described first distance when described tubular wall is at idle state, between described area pressed, measure described second distance when described tubular wall is in assembled configuration.
Therefore, this ratio means sizable deformability of tubular wall, and this allows to make the polytype elongated member of channel adaptation and/or allow large clamping force to pass to elongated member.
In this application, " tubular wall is at idle state " refers to tubular wall and leaves unused, and it is not also out of shape by the elongated member inserted in passage by pressing force.When tubular wall is at idle state, cover is in the configuration different from assembled configuration and clamping configuration.
According to an embodiment of the invention, when tubular wall is at idle state, described passage roughly has rectangular shape, the ratio of the length of described rectangular shape and the width of described rectangular shape between 110% and 250%, preferably between 150% and 240%.
Therefore, when tubular wall is deformed to its assembled configuration from idle state, passage roughly has identical size in multiple directions, and this allows to insert the elongated member with roughly as broad as long cross section in the channel, and this cross section is circular or non-circular ellipse in this way.
According to a modified example of the present invention, the length of rectangular shape is between 10mm and 50mm, and the width of rectangular shape is between 5mm and 30mm.Therefore, use such length and width, rectangular shape is suitable for following elongated member and inserts in passage, and the cross section of described elongated member has the size between 5mm and 30mm.
According to an embodiment of the invention, when described tubular wall is at idle state, described outer surface roughly has the cylindrical shape comprising elliptical base, and described cylindrical body such as has round base portion or non-circular elliptical base.
Therefore, this oval outer surface allows to distribute quite equably the mechanical stress of being born by tubular wall, and this allows the working life maximizing cover.In addition, when bifocus elliptical base, because outer surface is asymmetric, operator can find area pressed rapidly, because summit place that is that area pressed is positioned at the protrusion of elliptical base or that focus on.
According to an embodiment of the invention, described cover also comprises the protuberance and depressed part alternately arranged on the internal surface, described first contact segment and described second contact segment are formed by point other protuberance, and described protuberance is resiliently deformable according to the distortion of described tubular wall between described assembled configuration and described clamping configuration.
In other words, be there is the shape of star approx by the passage that the first and second contact segments partly limit, because protuberance and depressed part replace.
Therefore, because protuberance is resiliently deformable, so this protuberance Absorbable rod clashes into and acoustic vibration.

According to an alternative of last mode of execution, cover does not have protuberance and depressed part, and internal surface is smooth and directly forms the first contact segment and the second contact segment.
According to an embodiment of the invention, described protuberance comprises central protuberance and side direction protuberance, described central protuberance is arranged closer to the central area of described passage compared with described side direction protuberance, described side direction protuberance has a hardness, and described hardness is determined described elongated member to be repositioned onto in described central area.
Therefore, this side direction protuberance avoids the bias of elongated member, and central protuberance ensure that the translation along elongated member is braked.In addition, this protuberance improves the performance covering on and absorb shock and vibration aspect due to its resiliently deformable.
According to a modified example of the present invention, the first contact segment extends in the first length between 2mm and 30mm, the second contact segment in the second length between 2mm and 30mm on extend.Therefore, this first width and the second width allow to transmit clamping force, and described clamping force fixedly can have the elongated member of the transverse dimension typically between 4mm and 30mm.Advantageously, the first width and the second width roughly equal.In fact, the size of cover, especially the size of the first contact segment and the second contact segment is determined according to the transverse dimension of elongated member.
According to a modified example of the present invention, the minimum interval between the first contact segment and the second contact segment is between 3mm and 28mm.Therefore, this minimum interval allows to transmit clamping force, and this clamping force fixedly can have the elongated member of the transverse dimension of typical case between 4mm and 30mm.In fact, the size of cover, especially this minimum interval is determined according to the transverse dimension of elongated member.Such as, be that to have diameter be the pipe of the circular cross-section of D, the minimum interval between the first and second contact segments is between 50% and 100% of diameter D at elongated member.
According to a modified example of the present invention, outer surface has the degree of depth between 5mm and 200mm measured by the direction of extension along passage.The degree of depth of outer surface is larger, and it is more that elongated member quilt cover covers.When the degree of depth of outer surface is between 5mm and 50mm, cover is short and forms ring in this case.
According to a modified example of the present invention, described tubular wall has the thickness between 2mm and 15mm, and this thickness comprises possible protuberance.
According to a modified example of the present invention, described tubular wall has the thickness along internal surface change.

According to a modified example of the present invention, described cover can comprise the hole with open cavity and/or the hole with enclosed cavity.Therefore, cover has the extraordinary ability absorbing vibration and clash into.
According to an embodiment of the invention, described tubular wall, described first contact segment and the second contact segment have the hardness between 50ShoreA and 60ShoreA.
Therefore, this hardness allows to manufacture a kind of cover, and this cover has wear-resistant mechanical strength, toughness, optimum balance between absorption acoustic vibration ability and elasticity.
According to a modified example of the present invention, described cover comprises more than two contact segments.Such as, cover can comprise the first contact segment, the second contact segment and the 3rd contact segment.In assembled configuration, tubular wall is resiliently deformable by the pressing force applied in roughly relative direction on the outer surface, to make the first contact segment, the second contact segment and the 3rd contact segment separately.Pressing force effectively applies in roughly relative direction, and thus pressing force roughly converges to central point place, so that the additional effect of pressing force disappears substantially.Compared with assembled configuration, in clamping configuration, when there is no pressing force, first contact segment, the second contact segment and the 3rd contact segment are separated smaller, make when at least one elongated member described is inserted in passage, clamping force can be sent at least one elongated member described by the first contact segment, the second contact segment and the 3rd contact segment.
Therefore, this cover allows to wrap the elongated member with general triangular cross section.In operation, in order to make the tubular wall of cover be out of shape, operator simultaneously applies pressing force on three sidepieces corresponding with (first, second, and third) three contact segment of tubular wall.Alternatively, cover can slide in connecting rod (tringle) by operator, and the internal geometry of connecting rod allows to apply pressing force on area pressed, therefore allows cover is out of shape.Then, pipe can import in cover by operator.When cover relative to pipe near or on its final position time, the desirable lower connecting rod of operator and if needed carry out the final adjustment of the position of cover.
According to an embodiment of the invention, described tubular wall produces from spray or compacting.
Therefore, this tubular wall can have complicated geometrical shape, and directly forms the profile closed after its manufacture, and without the need to extra manufacturing operation, this gives cover high mechanical properties at low cost.
In addition, the invention provides a kind of assembly, described assembly comprises at least one elongated member of such as pipe or cable, and the feature of described assembly is, described assembly comprises according to cover of the present invention, and described cover is arranged to wraps at least one elongated member described.
Therefore, this assembly can fast and assembled simply, and not to elongated member scraping or mark.Meanwhile, because the first and second contact segments can provide the large area disturbed with elongated member, so cover ensures the effective brake of cover along the translation of elongated member.In addition, because the operation of cover is very simple, so cover can very accurately be placed on elongated member by operator.Operator uses instrument or does not such as manually use instrument to apply pressing force.
According to an embodiment of the invention, at least one elongated member described roughly has the cylindrical shape comprising round base portion, and when tubular wall is at idle state, described outer surface roughly has the cylindrical shape comprising elliptical base.

Embodiment
Fig. 1,2,3,4 and 5 illustrates according to assembly 51 of the present invention, and this assembly comprises the pipe 52 forming elongated member 52 and the cover 1 being arranged to wrap pipe 52.In the example of Fig. 1 to 5, pipe 52 roughly has the cylindrical shape comprising round base portion, and the diameter of round base portion is approximately 10mm.
Fig. 1 illustrates cover 1.As shown in Figure 1, cover 1 comprises tubular wall 2, and tubular wall has outer surface 4 and internal surface 6.Internal surface 6 is defined for the passage 8 of containing tube 52.Passage 8 passes cover 1 along direction of extension Z8.
Cover 1 also comprises the first contact segment 11 and the second contact segment 12.First contact segment 11 extends on the relative sidepiece of internal surface 6 with the second contact segment 12.
The relative sidepiece of internal surface 6 extends in the both sides of passage 8.In the example of fig. 1, relative sidepiece comprises high sidepiece and low sidepiece.First contact segment 11 extends on high sidepiece, and the second contact segment 12 extends on low sidepiece.First contact segment 11 defines the high portion of passage 8, and the second contact segment 12 defines the lower curtate of passage 8.
Tubular wall 2 is elastically deformables.Therefore, tubular wall comprises thermoplastic elastic material herein, is therefore polypropylene (PP) and ethylene propylene diene rubber (EPDM).Tubular wall 2, first contact segment 11 and the second contact segment 12 have the hardness between 50ShoreA and 60ShoreA herein.
In the example of Fig. 1 to 5, tubular wall 2 is made up of sole layer, and tubular wall 2 can produce from spray or compacting.Tubular wall 2, first contact segment 11 and the second contact segment 12 are one.
As Fig. 2,3 and 4 relatively shown in, tubular wall 2 is resiliently deformable between assembled configuration (Fig. 2 and 3) and clamping configuration (Fig. 4) especially.
In assembled configuration (Fig. 2 and 3), tubular wall 2 is out of shape by the pressing force F be applied in relative direction on outer surface 4, the first contact segment 11 and the second contact segment 12 to be separated, make pipe 52 can be inserted in passage 8, as shown in Figure 3.
Pressing force F is applied in relative direction.Therefore, point other straight line or the direction (nondirectional of pressing force F; Namely route direction is not had) form zero degree each other, because other direction of these points roughly conllinear.
As compared to assembled configuration (Fig. 2 and 3), in clamping configuration (Fig. 4), when there is no pressing force F, first contact segment 11 and the second contact segment 12 are separated smaller, make when pipe 52 inserts in passage 8, first contact segment 11 and the second contact segment 12 can transmit clamping force to pipe 52, and its result is pointed out by Fig. 4 arrow S.
Because do not have pressing force F, so compare with assembled configuration (Fig. 2 and 3), in clamping configuration (Fig. 4), tubular wall 8 is out of shape smaller.As compared to assembled configuration (Fig. 2 and 3), in clamping configuration (Fig. 3), the first contact segment 11 and the second contact segment 12 are separated smaller.
In order to allow operator to apply pressing force F on outer surface 4, described outer surface 4 has two area presseds 4.1 and 4.2.Area pressed 4.1 and 4.2 is arranged to and applies pressing force F.
Area pressed 4.1 and 4.2 is relative.Each area pressed 4.1 and 4.2 between two described relative sidepieces, the high sidepiece namely on Fig. 2 or 3 and between low sidepiece.Each area pressed 4.1 and 4.2 is positioned at zone line place herein, and zone line and the first contact segment 11 and the second contact segment 12 are located equidistantly.Area pressed 4.1 and 4.2 is positioned on outer surface 4 relative to one another.
Except assembled configuration (Fig. 2 and 3) and clamping configuration (Fig. 4), tubular wall 2 has idle configuration (Fig. 1).
When tubular wall 2 is in idle state (Fig. 1), outer surface 4 roughly has cylindrical shape, and therefore this cylindrical body has bifocus elliptical base is not round base portion.Because outer surface 4 is asymmetric, operator can find area pressed 4.1 and 4.2 rapidly, because summit place that is that area pressed is positioned at the protrusion of elliptical base or that focus on.
First contact segment 11 this be in approximate 7mm the first length on extend.Second contact segment 12 this be in approximate 7mm the second length on extend.
Outer surface 4 has along the degree of depth P4 approximating 28mm measured by direction of extension Z8.Tubular wall 2 has the thickness E 2 between 3mm and 7mm herein.Therefore, tubular wall 2 has the thickness E 2 changed along internal surface 6, and thickness E 2 is measured between outer surface 4 and internal surface 6, therefore radially direction and measuring herein.
In order to determine the size of tubular wall 2, first distance L2.1 approximates 1.4 with the ratio of second distance L2.2 herein, when tubular wall 2 measures this first distance when idle state (Fig. 1) between area pressed 4.1 and 4.2, between area pressed 4.1 and 4.2, measure this second distance when tubular wall 2 is in assembled configuration (Fig. 2 and 3).
When tubular wall 2 is when idle state (Fig. 1), passage 8 roughly has rectangular shape, namely long than wide length.The length D8 of rectangular shape approximates 200% with the ratio of the width W 8 of rectangular shape.
When tubular wall 2 is deformed to its assembled configuration (Fig. 2 and 3) from idle state (Fig. 1), passage 8 has size roughly equal in multiple directions, pipe 52 inserts in passage 8 by this permission, and this pipe has the circular cross section that diameter is 10mm.
Cover 1 also comprises and is alternately arranged in four protuberances 14 on internal surface 6 and six depressed parts 16.Each protuberance 14 has circular shape and the size (height and width) between 1mm and 10mm.
Protuberance 14 is according to the distortion of tubular wall 2 between assembled configuration (Fig. 2 and 3) and clamping configuration (Fig. 4) and resiliently deformable.Protuberance 14 especially has the effect absorbing shock and acoustic vibration by its resiliently deformable.
When cover 1 forwards clamping configuration to from idle configuration (Fig. 1), due to the insertion of pipe 52, can be observed the distortion of protuberance 14 and the small deformation of tubular wall 2.
In the example of Fig. 1 to 5:
-when tubular wall 2 is in idle configuration (Fig. 1), outer surface 4 has ellipse and non-circular cross section;
-when tubular wall 2 is in assembled configuration (Fig. 2), namely during tubular wall resiliently deformable, outer surface 4 has oval cross section, and the ratio between oval major axis and minor axis is than little when idle configuration (Fig. 1) is middle; Relative to idle configuration (Fig. 1), time in assembled configuration (Fig. 2), minor axis and major axis are put upside down;
-when tubular wall 2 is in the clamping configuration (Fig. 4), namely tubular wall a little resiliently deformable time, outer surface 4 has the cross section of circular; In other words, tubular wall 2 has the shape of the substantial cylindrical of the base portion comprising circular; This shape allows to have an assembly 51, and this assembly has the outer geometrical shape of circular at cover place, this avoid the angle controlling cover 1 in order to be installed on the rolling stock by assembly 51 directed; When particular surroundings in the motor vehicle needs the outer geometrical shape of non-circular ellipse on the contrary, the outer geometrical shape of adjustable cover.
First contact segment 11 and the second contact segment 12 are formed by point other protuberance 14.Therefore, because protuberance 14 and depressed part 16 replace, so the passage 8 defined by the first contact segment 11 and the second contact segment 12 part has the shape of approximate star.
In clamping configuration (Fig. 4), protuberance 14 resiliently deformable and against the periphery of pipe 52, this produces clamping force S.Clamping force S from resiliently deformable, therefore from the hardness of tubular wall 2.In the example of Fig. 1 to 5, clamping force S also produces from the first contact segment 11 and the second contact segment 12.
In order to embody the distortion of tubular wall 2, Fig. 1 and 2 illustrates the span D11.12 between the first contact segment 11 and the second contact segment 12.Fig. 1 and 2 relatively illustrates that span D11.12 increases when tubular wall 2 is deformed into assembled configuration (Fig. 2) from idle configuration (Fig. 1).
Similarly, Fig. 1 and 2 illustrates lateral separation D8, and this lateral separation is corresponding with the size of passage 8.Fig. 1 and Fig. 2 relatively illustrates when tubular wall 2 is deformed into assembled configuration (Fig. 2) from idle configuration (Fig. 1), and lateral separation D8 reduces.
Figure 11 illustrates according to assembling method 80 of the present invention.In operation, according to the assembling method 80 of Figure 11, cover 1 is assembled on pipe 52 by operator, and this assembling method comprises the following steps:
81) (Fig. 2) is by making described tubular wall 2 be out of shape by operator pressing force F be manually applied on described outer surface 4 in roughly relative direction, to make described first contact segment 11 and described second contact segment 12 separately; Described tubular wall 2 in assembled configuration (Fig. 2 and 3),
82) pipe 52 is inserted in described passage 8 by (Fig. 3), and
83) (Fig. 4) cancels pressing force F; Described tubular wall 2 is in clamping configuration, in this clamping configuration, compared with assembled configuration (Fig. 2), described first contact segment 11 and described second contact segment 12 are separated smaller, make described first contact segment 11 and described second contact segment 12 clamping force S be passed to described pipe 52.
Cover 1 can be arranged on any pipe 52 fast and simply, and does not swipe or mark pipe 52.Cover 1 ensures that cover 1 is braked along effective translation (Z8) of pipe 52, because the first contact segment 11 and the second contact segment 12 can provide the large confusion area with pipe 52.In addition, because the operation of cover 1 is very simple, so cover 1 can very accurately be placed on pipe 52 by operator.
Fig. 6,7,8 and 9 illustrates assembly 151 second embodiment of the invention and cover 101.Fig. 6,7,8 101 similar with cover 1 to assembly 51 respectively with cover with the assembly 151 of 9, the description of above composition graphs 1 to 5 and 11 assemblies provided 51 and cover 1 can remove to Fig. 6,7, in the assembly 151 of 8 and 9 and cover 101, except the significant difference described below.
Fig. 6,7,8 adopts identical number designation to add 100 with the assembly 151 of 9 or the constituent element of cover 101 with at its structure or functionally identical or corresponding assembly 51 or the constituent element that covers 1.Therefore limit pipe 152, the tubular wall 102 with outer surface 104 and internal surface 106 and the first contact segment 111 and the second contact segment 112, internal surface limits path 10 8.
The same as cover 1, cover 101 comprises and is alternately arranged in protuberance on internal surface 106 and depressed part 116, and the first contact segment 111 and the second contact segment 112 are formed by dividing other protuberance.
Assembly 151 and cover 101 and assembly 51 and cover 1 different, especially comprise central protuberance 114.1 and side direction protuberance 114.2 because of protuberance.Compared with side direction protuberance 114.2, central protuberance 114.1 is arranged closer to the central area 108.0 of path 10 8.
As tubular wall 2, under the effect being applied to the pressing force F in opposite direction, tubular wall 102 is from assembled configuration (shown in Fig. 8 dotted line) resiliently deformable to clamping configuration (not shown), the first contact segment 111 and the second contact segment 112 to be separated, pipe can be inserted in path 10 8.
Central authorities' protuberance 114.1 and side direction protuberance 114.2 be resiliently deformable according to the distortion of tubular wall 102 between assembled configuration (Fig. 8 dotted line shown in) and clamping configuration.
In the example of Fig. 6 to 9, as Fig. 9 arrow C represents, side direction protuberance 114.2 has a hardness, and this hardness is determined pipe 152 to be repositioned onto in central area 108.0.Therefore side direction protuberance 114.2 avoids the bias of pipe 152 in clamping configuration, and central protuberance 114.1 is guaranteed brake along the translation of pipe 152 and contribute to guaranteeing the function of cover 101, this function is such as the absorption of shock and vibration or the location on outer member.
Figure 10 illustrates assembly 251 according to the 3rd mode of execution of the present invention and cover 201.The assembly 251 of Figure 10 is similar with covering 1 to assembly 51 respectively with cover 201, and what above composition graphs 1 to 5 and 11 provided can remove to the assembly 251 and cover 201 of Figure 10, except the significant difference described below to the description of assembly 51 and cover 1.
The constituent element of the assembly 251 of Figure 10 or cover 201 adopts identical number designation to add 200 with at structure or functionally identical or corresponding assembly 51 or the constituent element that covers 1.Therefore pipe 252, tubular wall 202 is limited, passage 208, and the first contact segment 211 and the second contact segment 212.
As tubular wall 2, under the effect being applied to the pressing force F in opposite direction, tubular wall 202 is from assembled configuration (shown in Figure 10 dotted line) resiliently deformable to clamping configuration (shown in Figure 10 solid line), the first contact segment 211 and the second contact segment 212 to be separated, pipe 252 can be inserted in passage 208.
Assembly 251 and cover 201 and assembly 51 are with to cover 1 different, this is especially because pipe 252 roughly has the prismatic shape comprising rectangular base, and because in idle configuration and/or assembled configuration (shown in Figure 10 solid line) time, outer surface 204 has the cylindrical shape of the elliptical base comprising sub-circular.
When assembling, pressing force F allows outer surface distortion until the cylindrical body of non-circular ellipse, and pipe 252 inserts in passage 208 by this permission.
Figure 12 and 13 illustrates assembly 351 according to the 4th mode of execution of the present invention and cover 301.Assembly 351 is similar with covering 1 to assembly 51 respectively with cover 301, and the description of above composition graphs 1 to 5 and 11 assemblies provided 51 and cover 1 can be removed in assembly 351 and cover 301, except the significant difference described below.
The constituent element of assembly 351 or cover 301 adopts identical number designation to add 300 with at its structure or functionally identical or corresponding assembly 51 or the constituent element that covers 1.Therefore tubular wall 302, outer surface 304, internal surface 306 and passage 308 is limited.
As tubular wall 2, under the effect being applied to the pressing force in opposite direction, tubular wall 302 is from assembled configuration resiliently deformable to clamping configuration (Figure 12 and 13).
Assembly 351 and cover 301 and assembly 51 are with to cover 1 different, this is especially because assembly 351 comprises two pipes 352 in the passage 308 be inserted in clamping configuration, and because cover 301 has two the first contact segments 311.2 and 311.2 and two the second contact segments 312.1 and 312.2.First contact segment 311.1 and the second contact segment 312.1 wrap pipe 352, and the first contact segment 311.2 and the second contact segment 312.2 wrap another pipe 352.
In addition, assembly 351 and cover 301 and assembly 51 and cover 1 different, this is because outer surface 304 has the shape of substantially elliptical in clamping configuration (Figure 12), and outer surface 4 has the shape of circle in clamping configuration (Fig. 5).
Certainly, the mode of execution that the embodiment described by the invention is not restricted in the present patent application or those skilled in the art grasp.When not exceeding protection scope of the present invention, by use any with present patent application in the element of element equivalent pointed out, other mode of execution can be considered.
