Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the schematic diagram of internal structure of locating shaft of the invention；
Fig. 3 is the present invention by the effect picture after Ultimate Shear.
Specific embodiment
As shown in Figure 1, this direct-burried composite cable, including cable main body, the position of the cable main body must be fixed, prevent
It shifts when being sheared by top, therefore needs that one or more positioning pluging rod 41 is arranged in the bottom of cable main body, positioning is inserted
Bar 41 is inserted in positioning cable main body in ground；
In the present embodiment, cable main body includes a serving 1, has an installation cavity 11, internal core wire 2 inside serving 1
It is installed in installation cavity 11,11 inner wall of installation cavity is provided with a rotation layer 3, and rotation 3 outer wall of layer is close to 11 inner wall of installation cavity and is set
It sets, the sliding-rail groove 12 of one or more, every sliding rail is equidistantly offered along serving length direction on the plane of symmetry of installation cavity 11
A spring 8 is respectively mounted in slot 12；
Wherein, the two sides of internal core wire 2 alongst equidistantly open up more than one positioning aperture 7, and rotation layer 3 is opposite
Each positioning aperture 7 opens up a through-hole, and piece locating shaft of insertion setting, locating shaft 9 and through-hole wall is beaten in each through-hole
Glue is fixed, and has a position-limited needle 31 in locating shaft 9, and the two sides of position-limited needle 31 pass through perforative positioning shaft hole among locating shaft 9
And the two sides of locating shaft are stretched out in, the side extension end of position-limited needle 31 is inserted into sliding-rail groove 12, and is inserted in 12 bottom of sliding-rail groove
In the limit aperture 51 that face opens up, the other end of locating shaft 9 is inserted in positioning internal core wire 2 in the positioning aperture 7 of internal core wire 2.
As shown in Fig. 2, position-limited needle 31, which is inserted into sliding-rail groove side, is set with a sliding shaft sleeve 34,34 one end of sliding shaft sleeve with
8 gluing water of spring is adhesively fixed, and the bottom surface gluing hydropexis of the other end and sliding-rail groove of spring 8, the purpose of sliding shaft sleeve is not
Which kind of expanding-contracting action pipe position-limited needle makees, and spring one end can be connect with position-limited needle always；
In the present embodiment, internal core wire with serving after assembling, and the spring 8 in sliding-rail groove 12 stretches, 31 one end of position-limited needle
It is inserted in limit aperture 51.After locating shaft is inserted in the positioning aperture of internal core wire, position-limited needle is ejected, so that position-limited needle
One end it is concordant with the end face of locating shaft, and position-limited needle then again towards sliding-rail groove direction eject so that originally do not buckle into limit
Position-limited needle in the aperture of position is inserted in limit aperture, and state at this time is that spring is stretched, and whole internal core wire is vacantly set to
In installation cavity.
Positioning shaft hole inner wall offers the sliding cavity 32 of circle recess, the fixed weldering on the position-limited needle in the sliding cavity 32
The baffle ring 33 of a circle is connect, position-limited needle 31 is inserted into sliding cavity one end and is set with a reset spring 35,35 one end of reset spring and sliding
Chamber 32 contacts, and the other end is contacted with the end face of baffle ring 33.State in Fig. 2 is then the state that internal core wire is separated with locating shaft, this
When reset spring reset, baffle ring contacts with sliding cavity one end inner wall, and one end of position-limited needle is extracted out of limit aperture, at this time
The spring reset being stretched, so that entirely rotation layer playback, as shown in figure 3, be at this time usually to be fallen after internal core wire is sheared,
Under the action of reset spring, the outboard end of position-limited needle stretches out in the outside of locating shaft again, and internal core wire is fallen fixed up and down
The right side of position axis, as why being bound on right side, followed by introduction.When state in Fig. 3, upper and lower locating shaft this
When perpendicular to horizontal plane, in this way when continuing to push, the spacing between upper and lower locating shaft is slowly close, and last locating shaft up and down connects
Touching support is resisted shearing or is pushed, and using the intensity of locating shaft, realizes the support to top, and then have very top
Anti-pressure ability.
In the present embodiment, serving 1 and rotation layer 3 are all made of the plastic material with toughness and are made.The one of serving
End opening is closed and is formed a contact-segment 6 by the elastic force of serving, and rotation 3 one end of layer is provided with an open slot 5, this is opened
Mouth slot 5 is set to 6 distal end one side of contact-segment, and after rotation layer 3 rotates counterclockwise 90 degree, open slot 5 faces contact-segment.Due to outer
Tegillum and rotation layer are all made of the plastic material with toughness and are made, thus its can be closed automatically it is circular outer as one
Tegillum, and in pressurized process, serving is flattened with rotation layer, is flattened with continuous, and horizontal spacing is increasing, longitudinal
Spacing is smaller and smaller, i.e., total becomes elliptical shape, separates locating shaft out of, internal core wire positioning aperture, this
When rotate layer under the action of the spring and rotate counterclockwise 90 degree, as shown in Figure 3.
Wherein, the arc length of sliding-rail groove 12 is that a quarter of entire installation cavity internal diameter is long, when being resetted due to the rotation rotation of layer 3
It rotates counterclockwise, and after locating shaft is separated out of positioning aperture, whole internal core wire is vertically to fall down, therefore rotating
After layer is rotated by 90 °, internal core wire is located at right side, and in the present embodiment, the diameter of internal core wire should be sufficiently large, make its be located at it is right
It when in the space of side, can be contacted with the positioning shaft portion of bottom, the locating shaft at top can be with internal core wire when pushing in this way
Outside face contact is pushed with continuous, and internal core wire can be squeezed out constantly towards right-hand end, so the closed contact-segment quilt of script
It struts, and open slot is stretched, finally when the locating shaft of the locating shaft at top and bottom contacts, internal core wire can pass through outer quilt
The contact jaw of layer and the opening layer for rotating layer are discharged outside to, and prevent front shear, improve safety.
The beneficial effects of the present invention are: the one, present invention in routine use, is positioned, by inner core by the locating shaft of two sides
Line is vacantly erected, and suspended state is at, and increases cushioning ability and heat-sinking capability；
Two, the present invention can to rotate 90 degree of layer rotation after the pressure by top, and then using perpendicular to level
The locating shaft in face is supported as resistance to compression and is used, and has extraordinary top anti-pressure ability；
Three, the present invention is after power limit pressure, enable to internal internal core wire ejected under the action of locating shaft to
Shearing is hidden in the outside of serving.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
