Protect core wire.
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 structural schematic diagram of the present invention after wherein side core wire is extruded.
Coding in figure is respectively as follows: 1 for engaging lug, and 2 be interconnecting piece, and 3 be core wire accommodating chamber, and 4 be extruding cavity, and 5 be protection
Chamber, 6 be buckle, and 7 be arcuate extensions, and 8 be elastic sheet metal, and 9 be connection strap, and 11 be arc support, and 12 be core wire, and 13 are
Positioning region, 14 be lock screw, and 15 be arc positioning chamber.
Specific embodiment
As shown in Figure 1, a kind of safety cable, including the circular cable serving being made of four interconnecting pieces 2, this implementation
Cable serving can be PVC material in example, and the fan-shaped shape of four interconnecting pieces 2, the opposite face of four interconnecting pieces 2 mutually connects
It touches, all has a core wire accommodating chamber 3 in each interconnecting piece 2, a core wire 12 is provided in each core wire accommodating chamber 3；
Interconnecting piece 2 is respectively provided with an opening close to center of circle direction side, and open end two sides are respectively arranged an arcuate extensions 7, and two
An extruding cavity 4 is formed between arcuate extensions 7, the opposite face of two arcuate extensions 7 is respectively provided with one towards core wire accommodating chamber
The connection strap 9 of extension, an arc support 11 is provided on connection strap 9, and the core wire of two arc supports 11 of face holds
It receives and is provided with corresponding positioning region 13 on 3 face of chamber, an arc positioning chamber 15 is arranged in 13 opposing arcuate support portion side of positioning region,
Core wire 12 is set between arc support 11 and arc positioning chamber 15, and each arcuate extensions 7 are circular anti-around composition one
Protect chamber 5.
Wherein, extruding cavity 4 is " V "-shaped, and the inner end of core wire 12 faces the setting of extruding cavity 4, the output end of extruding cavity 4
Conducting is connect with intermediate protection chamber 5.Core wire 12 is set in core wire accommodating chamber 3, due to the intermediate protection for forming a hollow out
Chamber 5, therefore the heat of core wire can pass rapidly through extruding cavity and enter the intermediate intracavitary carry out rapid cooling of protection, heat dissipation performance is big
Big to be promoted, core wire is supported between arc support and positioning region before not ejecting, as long as therefore slight squeeze, can make
It obtains extruding cavity to be strutted slightly, realizes the buffering to extruding.
But when extruding force is excessive, the core wire of respective side can be extruded into from extrusion chamber to intermediate protection chamber into
Row secondary protection, preferably protects core wire, prevents the impaired of core wire, once as shown in Fig. 2, core wire enters intermediate protection chamber
It is interior, the core wire of the squeeze side can be protected, prevent the damage of the core wire of respective side.
Wherein, the one side of interconnecting piece 2 is provided with more than one buckle 6, the another side of interconnecting piece in linear type
The buckle of face side is provided with corresponding catching groove (not shown), is fastened and is connected with catching groove by buckle 6 between adjacent two interconnecting piece 2
It connects, both ends are each provided with an engaging lug 1 on the exterior arc surface of interconnecting piece, contact setting between adjacent two engaging lug 1, pass through phase
Two engaging lugs of neighboring terminal both pass through one lock screw 14 of setting, and the other end of lock screw 14 passes through a nut check.Due to
Entire cable is spliced by four parts, as long as therefore a portion it is impaired, dismantle lower a portion replacement, be not necessarily to
Whole cable is replaced, and the later period facilitates the dismounting of core wire to recycle.The present invention is applicable not only to a cable, and is suitable for more
The integration of the different cables of stock, so that independently using being independent of each other between each stock cable, and can solve wiring problem, it is empty to reduce wiring
Between, shape is more clean and tidy.
Insertion is provided with elastic sheet metal 8 in interconnecting piece 2, and setting elastic sheet metal 8 delays primarily to increasing rebound
Effect is rushed, so that the anti-extrusion ability of cable entirety increases, and setting metalwork can be effective against shearing, and will not influence
The bending of cable entirety.
The beneficial effects of the present invention are: the present invention has extraordinary heat dissipation performance and anti-extrusion ability, it can be in office
When the core wire of meaning side is squeezed, the protection that the core wire of respective side is squeezed into centre is intracavitary, realizes secondary protection, effectively protects
Protect core wire.
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.
