Portion 6 only curved strip 5 and is alternatively arranged to item portion 6, and only curved strip 5 is to support from the surface of graded layer 1 oppositely extending panel outward
Item portion 6 includes support column and resistance item, and support column is from the vertical bar column of the surface outwardly convex of graded layer 1, and resisting item is from branch
Only curved strip 5 vertical bar column close to extension of the end of dagger to two sides.
The cross-sectional area of interior paste layer 2 is circular ring shape, and electric wire is installed in the inner cavity of interior paste layer 2, is wrapped up and being protected by interior paste layer 2
Shield, interior paste layer 2 are wrapped up by graded layer 1, wherein filling chamber is alternatively arranged on the axial direction of interior paste layer 2, the axis of interior paste layer 2
It can be understood as the extending direction of cable to direction to paste after graded layer 1 injects gradually deep chamber 22 by insertion section by extrados 11
It closes on the outer surface of interior paste layer 2, so that the two inlays connection, continuous can must be installed on the extending direction of cable gradual
Layer 1 protects interior 2 surface of paste layer, in the selection of material, is suitble to the material for selecting quality softer since interior paste layer 2 is close to cable
Matter, so the thermal expansion rate of rigidity or graded layer 1 that the rigidity of graded layer 1 is greater than interior paste layer 2 will be lower than the heat of interior paste layer 2
Rise rate, i.e., with the variation of temperature, graded layer 1 hardly happens variation, gradual in this way when interior 2 expanded by heating of paste layer
The deformation that layer 1 keeps out interior paste layer 2 by the insertion section being embedded in interior paste layer 2 particularly can have interval in graded layer 1
Multiple insertion sections of arrangement are adapted to multiple filling chambers, and the end of connection chamber 21 can be understood as the inside table of paste layer 2 in deeply
The one end in face, anti-folding part are located at the outer surface of graded layer 1, when cable receives external force and is coiled, is bent, only curved strip
5 can be inserted into it is close when bending support in item portion 6, i.e., only curved strip 5 can be inserted into the groove to item portion 6, when only curved strip 5 is against to item
When the end in portion 6, cable is no longer able to be bent due to stopping the resistance of curved strip 5, to protect cable, avoids occurring to bend and damage
It is bad, particularly, only curved strip 5 and it is alternatively arranged to item portion 6 along the extending direction of cable, and only curved strip 5 are set as needed
6 spacing distance of item portion and it is separated by quantity with supporting, different number can be arranged between adjacent two only curved strip 5 supports item portion 6.
Extrados 11 is the strip plate that in homogeneous thickness, cross section is arc curved strip.
The cross section of extrados 11 is arc curved strip, and the angle of curved strip is 180 degree, in this way, can pass through two panels extrados
11 is fully wrapped around by interior paste layer 2.Insertion section includes stopping rising by plate 12 and going deep into item 13, and the plate 12 that only rises is from the lower surface of extrados 11
The surface plate that depth becomes larger along the circumferential direction gos deep into the lower end side that item 13 is the vertical plate 12 that only rises and along the plate that only rises
The rectangular preiection item that the extending direction of 12 lower edge reversely protrudes.
The shape of insertion section can cooperate the shape of filling chamber, first by going deep into item 13 far from the first of 11 side of extrados
Beginning is inserted into the initial end that gradually deep chamber 22 is located at interior 2 outer surface side of paste layer, and graded layer 1 is chimeric along the gradually deep rotation of chamber 22,
So that only rise in the insertion connection chamber 21 of plate 12, one, gradually the both sides of the face of deep chamber 22 can prevent to go deep into the both side ends of item 13
Positioned at intracavitary, graded layer 1 is avoided to be detached from, two, the plate 12 that only rises stops the contracting of interior paste layer 2 to be risen variation by side.Such as Fig. 6 institute
Show, further includes the end side limiting unit for preventing the end of interior patch side from telescopic deformation occurs.End side limiting unit includes side board
31 and paste layer preapre for an unfavorable turn of events slot 32, side board 31 is the surface plate that the terminal edge of vertical graded layer 1 extends internally, and paste layer is preapred for an unfavorable turn of events slot
32 include epitaxy part and clamping plate portion, and epitaxy part is the outwardly extending surface plate in section side surface from interior paste layer 2, and clamping plate portion is vertical
Surface plate of the end of epitaxy part to the close extension in 1 side of graded layer.
The contracting that insertion section limits interior 2 axial inner of paste layer is risen, and the end side of interior paste layer 2 contracts to rise and needs to limit by end side
Portion limited, i.e., when the one end side portion of interior paste layer 2 expands, can prevent deformation with extrusion side baffle 31, when
It when interior paste layer 2 is shunk, can prevent from shrinking by 31 squeezing splints portion of side board, wherein where side board 31
The end of graded layer 1 can be understood as two sides outer end or the breaking part of cable.It further include the mistake for easy disassembly graded layer 1
To the portion that screws 4, it includes fixed lobe and pivot protrusion that misorientation, which screws portion 4, and fixed lobe is from the outwardly convex of interior paste layer 2
The vertical bar column risen, pivot protrusion are from the vertical bar column of the outer surface outwardly convex of graded layer 1, and pivot protrusion and fixed lobe are not
On same radial cross-section.
Misorientation screws graded layer 1 of the portion 4 for paste layer 2 in being inserted into and produces out of interior paste layer 2, in operation, pins solid
Fixed protrusion, exert a force pivot protrusion, graded layer 1 is rotated up to disengaging, wherein can also set in the upper surface that misorientation screws portion 4
Friction lines is set, the shape for the lines that rubs can be waveform, can increase frictional force when multidirectional force as much as possible in this way.
