Detailed Description
The invention is further described below with reference to the following figures and specific examples.
As shown in fig. 1 and 2, the insulation connection structure for a platform door of the present embodiment includes an insulation column 10, a first connector 20, and a second connector 30, wherein:
one end of the first connecting piece 20 is fixedly connected with one end of the insulating column 10, and the other end of the first connecting piece 20 is used for being directly or indirectly connected with a door body (not shown in the figure);
one end of the second connecting member 30 is fixedly connected with the other end of the insulating column 10, and the other end of the second connecting member 30 is used for being directly or indirectly connected with the civil structure.
Compared with the prior art which needs two mutually matched insulating assemblies, the insulating column 10 in the invention is a complete part made of insulating materials, no gap exists, a conductive path is not easy to form, and the safety and the reliability are greatly improved.
Furthermore, the side wall of the insulating column 10 is further provided with a plurality of annular grooves 11 surrounding one circle to prolong the creepage distance on the side wall along the axial direction of the insulating column, enhance the insulating performance on the side surface of the insulating column 10 and improve the insulating reliability.

The ends of the first connecting piece 20 and the second connecting piece 30 connected to the insulating column 10 are both provided with threads (not shown in the figure), and the ends of the two connecting pieces penetrate into the threaded blind holes 12 on the end face of the insulating column 10, so that the two connecting pieces are fixedly connected by means of thread matching. So set up, the screw on the terminal surface of insulating column 10 both sides is the blind hole, does not communicate each other between two holes, is separated totally by insulating column 10 between two connecting pieces promptly, has thoroughly avoided the formation of route.
As shown in fig. 3, preferably, the widths of the ends of the first and second connectors 20 and 30 connected to the insulating column 10 are D20 and D30, respectively, and the width of the end of the insulating column 10 is D10, wherein the width D10 of the insulating column 10 is greater than the widths D20 and D30 of the ends of the first and second connectors 20 and 30 connected to the insulating column 10, so that there is a certain proper distance Δ D from the outer edge of the end of the insulating column 10 to the connection between the insulating column 10 and the first and second connectors 20 and 30. The distance Δ D extends the creepage distance, and makes it difficult for a conductive path to be formed between the side surface and the end surface of the insulating column 10 even if dust or dew deposits on the outer side wall of the insulating column 10.
In a preferred embodiment, the relationship between the width D10 and the widths D20 and D30 satisfies
So that the insulating pillars 10 have relatively sufficient strength while it is difficult to form conductive paths on the surfaces thereof.
When the width of the insulating column 10 is large, the strength of the insulating column is higher, and the insulating column can provide support for a door body.

The nest block 50 is used for being connected with a door body fixed connection, and the door body can be adjusted in a flexible way for the distance on the horizontal direction between the civil engineering structure, or say that, when the door body is fixed for the distance on the horizontal direction between the civil engineering structure, no matter whether this distance is unanimous, all can adjust through slip nest block 50 for the insulating connection structure of this embodiment is very nimble when the installation, strong adaptability.
Two nuts 21 are further sleeved on the outer side of the first connecting piece 20, the two nuts 21 and the first connecting piece 20 are fixed in a threaded fit mode, and the two nuts 21 are correspondingly clamped on two sides of the sleeve block 50 so as to fix the sleeve block 50 on the first connecting piece 20. The two nuts 21 and the first connecting member 20 are fixed to each other when not being affected by the outside. When the device is installed, the position of the nut 21 can be adjusted by rotating the nut 21, so that the position adjustment of the sleeve block 50 relative to the first connecting piece 20 is very convenient.
Furthermore, the lower part of the sleeve block 50 is connected with an upright post 52, the lower part of the upright post 52 is used for being connected with the door body, and the sleeve block 50 is indirectly connected with the door body through the upright post 52, so that the assembly is more convenient.
After the civil structure is constructed, the phenomenon of natural settlement exists, so that additional compressive stress can be generated on the insulating structure and the door body, and the civil structure has destructiveness. To solve this problem, the upright 52 is further provided as a telescopic column whose overall length is variable. The upright column 52 is generally vertically arranged, decoupling of the door body and the civil engineering structure is realized in the length direction of the upright column 52, namely the vertical direction, in the process of settlement of the civil engineering structure, the length of the upright column 52 is correspondingly reduced to compensate for height change, so that pressure stress generated on the insulation structure and the door body is avoided, and the reliability and service life of the insulation structure are improved. At this time, the pillar 52 does not provide vertical support for the door body, but can still provide horizontal support for the door body.
Preferably, the sleeve block 50 is rotatably connected with the upright 51 to facilitate angle adjustment.
Further, a fixing base 60 is rotatably connected to the second connecting member 30 to facilitate angle adjustment. Wherein the fixing base 60 is fixedly mounted on the civil structure. For the convenience of installation, two or more elongated waist holes 61 are provided on the body of the fixing seat 60. An anchor bolt 62 is threaded into the waist hole 61, and the anchor bolt 62 is further threaded into the civil structure, so as to achieve the fixed installation of the fixing seat 60.
