Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as at this
It is all protected by Patent Law in the right of invention.
Embodiment 1 is cable overall structure diagram, a kind of resistance to voltage cable as shown in Figure 1, wherein including cable and
Cable joint-box, cable joint-box includes supporting shell 1, shares shell 2 is connected portion with conversion, supporting shell 1 including bottom surface, straight sided, oblique sliding surface and
Face is supported, bottom surface is horizontal-extending plane, and straight sided is the plane to extend straight up from the side of bottom surface, and oblique sliding surface is certainly
The upper end of the straight sided of both sides is upward and moves closer to the clinoplain extended, and the face that supports is the upper end for the oblique sliding surface for connecting both sides
Horizontal plane, it is right angled triangle, the triangular prism extended in the horizontal direction that share shell 2, which be cross-sectional area, shares the inclination of shell 2
Face is affixed with oblique sliding surface and contacts, and it includes telescopic chute 31, support flap 32 and guide rod portion 33 to convert the portion of being connected, and telescopic chute 31 is from front
The groove that face extends internally at bottom surface, for that will support in the guiding to telescopic chute 31 of flap 32, support flap 32 is in guide rod portion 33
The lower edge of vertical bar shaped tablet, support flap 32 is located in guide rod portion 33, supports the upside of flap 32 by articulated section and shares shell 2
Lower end connection.
Cable is placed in cable joint-box, and specifically, cable is located at the inside of supporting shell 1, is wrapped up and being protected by supporting shell 1
Shield.The profile of cable joint-box under normal circumstances is rectangle, i.e., the inclined surface for sharing shell 2 of both sides is affixed with oblique sliding surface, both sides
The upper surface for sharing shell 2 is in the same plane, and the outside side surface for sharing shell 2 of both sides is located at the straight sided of both sides respectively
On same vertical guide, so that the cross section on the vertical direction of cable joint-box in general is rectangle, wherein support flap
32 upside is connect by articulated section with the lower end for sharing shell 2, and the articulated section of both sides can be when initial to both sides
It shares shell 2 and generates a kind of opposite rotary force, i.e., in the case of not by excessive pressure, maintenance shares shell 2 and is located at a high position,
At this moment, the lower surface of supporting shell 1 can paste share on the ground shell 2 upper surface be cable upper surface, pressed for bearing
Power, when pressure is larger, sliding can be sloped downwardly to two respectively along oblique sliding surface by sharing shell 2, and at this moment, support flap 32 is in guide rod
Enter in telescopic chute 31 under the guiding in portion 33, moving down for shell 2 is shared with cooperation, until sharing the upper surface of shell 2 and supporting face position
When same level, no longer move, artificially supporting shell 1 can be designed to the height for sharing shell 2 it is consistent, in this way, working as
When supporting face and being located at same level of the upper surface of shell 2 and supporting shell 1 is shared, the lower end of shell 2 is shared, supports flap 32, bottom surface
It homogeneously is affixed on bottom surface, so that compression area becomes larger, promotes the resistance to pressure of cable, until excessive pressure elimination, shares shell 2
It is mutually ramped up again under the action of articulated section, becomes original shape.Guide rod portion 33 includes flat bearing and end follow block, and flat bearing is
The outwardly extending surface plate of notch lower edge of self extending slot 31, end follow block is the protrusion to raise up from the end of flat bearing
Item.
The lower end that support flap 32 can be limited on flat bearing by end follow block, prevent support flap 32 from above pushing away will share shell 2
It is detached from flat bearing in the process.As shown in Figure 2 and Figure 3, further include jacking portion, jacking portion includes turning to slot 41, curved prolonging bar 42, flat-top
It is gradually curved to turn to the medial end that slot 41 is self extending slot 31 for plate and the flexible connector for prolonging bar 42 and ceiling for connecting bending
Song extends to the straight slot of the inner cavity of supporting shell 1 upward, and the curved bar 42 that prolongs is positioned at telescopic chute 31 and to turn to the bendable bar in slot 41,
Ceiling is the surface plate of horizontal extension, and flexible connector connecting bending prolongs the upper end of bar 42 and the middle part of ceiling.
Jacking portion can promote the structural rigidity of supporting shell 1, and support flap 32 can contradict during sharing shell 2 and gliding to be located at
Turn in slot 41 and telescopic chute 31 it is curved prolong bar 42, the curved bar 42 that prolongs can be made of the material for having certain elasticity, such as rubber,
When supportting flap 32 and gradually putting in telescopic chute 31, the curved bar 42 that prolongs gradually rises upward, and ceiling is gradually increasing, when sharing shell 2
When positioned at lowest positions, ceiling is also by close to the inner surface in the face that supports, and flexible connector can be spring, to be used for
Reinforce the support strength of supporting shell 1.Further include oblique top plate, oblique top plate is reversed close to the edge of the oblique sliding surface of both sides from ceiling
The clinoplain plate extended downwardly.
Oblique top plate can play the role of oblique sliding surface certain Auxiliary support with the structural rigidity of lifting inclined sliding surface.It is supporting
There are anti-slip part 5, anti-slip part 5 to be alternatively arranged and constituted by anti-skidding single on face, anti-skidding single is to share shell 2 along in both sides
Spaced rectangular preiection item on line direction.
Anti-slip part 5 can not only play the role of preventing from being located at the pushing object skidding supported on face, but also can pass through
It is anti-skidding to protect the shell 2 of sharing of both sides not damaged by skidding impulsive contact force, such as when the sole of people steps down in the face of supporting and shares on shell 2
When, if without anti-slip part 5, it is possible that vamp horizontal sliding on supporting face, is at this moment located at the upper table for sharing shell 2 of both sides
Face can by horizontal direction, from the frictional force of sole, can cause to share the movement tendency that shell 2 generates a rotation, influence
Share the structure of shell 2, form it is steady, to be unfavorable for the firm of the construction of cable.Further include end side Easy glide plane 6, end side is easily sliding
Face 6 is from the upper surface of two anti-skidding singles of the most side for being located at anti-slip part 5 respectively from top to bottom and to sharing 2 side of shell
Close to the arc convex extended.
On the anti-skidding single on the outermost side of end side Easy glide plane 6, it is easily sliding that there is no end sides on the anti-skidding single of inside
Face 6, the protrusion direction of end side Easy glide plane 6 are the direction of the anti-skidding single far from inside, prevent the upside angle for sharing shell 2 from existing
The case where may contacting anti-skidding single during moving up and down and causing mobile have some setbacks, occurs, that is, share shell 2 from lower and
On " rising " during, may find that the end angle of upside touches the outer side surface of anti-skidding single, obstruct and share answering for shell 2
Position.
