Following detailed description of the invention will further illustrate this utility model in conjunction with above-mentioned accompanying drawing.

Detailed description of the invention

Refer to Fig. 1 and Fig. 2, its a kind of continuous supporting track 100 with insulation isolation mounting provided for embodiment of the present invention, it is used for embedded tracks system, the described continuous supporting track 100 with insulation isolation mounting includes 120, guide rail head 140 and an isolation mounting 160 at the bottom of 110, guide rail of a main body, and described main body 110 is arranged at the bottom of described guide rail between 120 and described guide rail head 140.

Described isolation mounting 160 includes 162, first flank 164 of a base and second flank 166, and described base 162 is offered a groove 163, described first flank 164 and described second flank 166 and is oppositely arranged on respectively on the sidewall of described groove 163.In present embodiment, the first flank 164 and the second flank 166 are separately positioned on sidewall 163a, 163b of groove 162.It is understood that isolation mounting 160 is sampled, elastomeric material is made.

As shown in Figure 2, first flank 164 offers a first recess 164a near one end of base 162, first recess 164a of the sidewall 163a of the groove 163 of the base 162 first protruding 165a that arrange one first protruding 165a, described groove 163 sidewall 163a setting corresponding with described first recess 164 and the first flank 164 engages to be fixed with the first flank 164 by base 162.Second flank 166 arranges one second protruding 166a near one end of base 162, protruding 166a is corresponding offers a second recess 165b for another sidewall 163b of the groove 163 of base 162 and second, and the second recess 165b of the sidewall 163b of groove 163 and the second of the second flank 166 the protruding 166a engaging are to fix base 162 with the second flank 166.

For strengthening the electric insulation effect of the continuous supporting track 100 with insulation isolation mounting, described isolation mounting 160 also includes an insulating barrier 180, described insulating barrier 180 is coated with at the bottom of guide rail 120 and houses to groove 163, the material of insulating barrier 180 is polypropylene (Polypropylene, PP), elastomeric material, polrvinyl chloride (Polyvinylchloride, or crosslinked polyethylene (CrossLinkedPolyethylene, XLPE) PVC).It is understandable that, insulating barrier 180 is divided into three parts, Part I 180a is arranged at the bottom of guide rail between 162 and the bottom land of groove 163, Part II 180b is arranged at the bottom of the first flank 164 and guide rail between 162 and Part III 180c is arranged at the bottom of the second flank 166 and guide rail between 162, and three parts 180a of insulating barrier 180,180b, 180c are coated with insulation completely by the bottom of guide rail 162.In present embodiment, the thickness of insulating barrier 180 is 0.5-5mm, and the thickness of insulating barrier 180 is respectively smaller than base the 162, first flank 164 and the thickness of the second flank 166.

For making insulation effect more preferable, as shown in Figure 3, one end of insulating barrier 180 extends with cladding main body 110 near one end of 162 at the bottom of guide rail along near the direction of guide rail head 140 from the bottom of guide rail 162, in present embodiment, the Part II 180b and Part III 180c of insulating barrier 180 extends one section to be coated with a part of main body 110 along near the direction of guide rail head 140 respectively away from one end of 162 at the bottom of guide rail.

During installation, first insulating barrier 180 is coated with at the bottom of guide rail 120, houses at the bottom of guide rail 120 to the base groove 162a of isolation mounting 160 the most again, then engage to wrap up main body 110 and guide rail head 140 with base 162 by first flank the 164, second flank 166 respectively.

What this utility model provided has the continuous supporting track 100 of insulation isolation mounting by being provided with insulating barrier 180 between isolation mounting 160 and guide rail, mainly utilize insulating barrier 180 that rail foot is fully wrapped around, even for more preferable insulating properties, insulating barrier 180 wrapped up main body 110 part to guide rail, without regard to guide rail head part, thus while improving insulating properties, do not affect vehicle travel.

It is understood that for the person of ordinary skill of the art, other various corresponding changes and deformation can be made according to technology of the present utility model design, and all these change all should belong to this utility model scope of the claims with deformation.
