Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described.
Non-bolt Double-layer seal type earthing box for electric cable of the present invention is applied to direct grounding box, protective earthing case, cross interconnected grounding box.The whole stainless steel that adopts, makes with Type of Welding.
Embodiment 1:
As shown in Figure 1, non-bolt Double-layer seal type earthing box for electric cable of the present invention adopts the form that pulls door lock 6 crimping rubber blanket 4 sealings, is divided into two parts of case lid assembly and case housing assy.Case lid assembly comprises 1,6 pulling buckles 2 of case lid (respectively install 2 all around, left and right is respectively installed 1), upper padding plate 3 and rubber blanket 4; Case housing assy comprises that 6 pull door lock 6 (corresponding pulling buckle 2, respectively installs 2 all around, and left and right is respectively installed 1), door lock mounting panel 7, lower bolster 5 and case shell 8.In the present embodiment, pulling door lock quantity is 6, but is not limited to 6.The door lock quantity of using, because of according to pulling the size of door lock holding capacity, size that box sealing requires test pressure to calculate and obtain, principle is: all suffered pressure of case lid while pulling total power of bearing to be greater than pressure testing.
As shown in Figure 2, upper padding plate 3 and lower bolster 5 are shaped as square, hollow slab, and overall dimension is long * wide: 520 * 300mm, middle part square opening size is long * wide: 470 * 250mm, thickness of slab: 15mm.
Rubber blanket 4 is double-layer sealing structure, is shaped as squarely, and overall dimension is long * wide: 520 * 300mm, and middle part square opening size is long * wide: 466 * 246mm, thickness: 2mm, surrounding has two
muscle, muscle spacing 10mm, as shown in Fig. 4 Fig. 5, rubber blanket inner side is provided with the projection that 10mm is high, during installation, location is used.
Upper padding plate 3 is welded in case lid 1 inner side oral area, pulling buckle 2 is welded in case lid 1 outside, and rubber blanket 4 is arranged between upper padding plate 3 and lower bolster 5, and lower bolster 5 is welded in case shell 8 outside oral areas, door lock mounting panel 7 is welded in lower bolster 5 outside surroundings, pulls door lock 6 to be arranged on door lock mounting panel 7 and is connected with pulling buckle 2.Upper padding plate 3 is welded in oral area inside case lid, lower bolster 5 is welded in oral area object outside case shell: welding is in order to prevent from installing rear gas leakage, affect sealing property, upper padding plate 3 is welded in oral area inside case lid, lower bolster 5 is welded in when case shell 8 outside oral areas are installed and guarantees that two cushion blocks can clamp rubber blanket 4, because upper and lower plate thickness is thicker, can guarantee between sealing surface indeformable, air tight.
Upper padding plate 3 and case lid 1 bottom fillet welding sealing in case lid assembly, the spot welding of oral area surrounding, rubber blanket 4 use glue are bonded on upper padding plate 3.Lower bolster 5 and the outside fillet welding sealing of case shell 8, the spot welding of oral area surrounding in case housing assy.Door lock mounting panel 7, pulling buckle 2 with pull door lock 6 to join weldering.
After case lid assembly and case housing assy fastening, will pull door lock 6 to pin pulling buckles 2, the effect of double-layer seal is played in be squeezed distortion compaction case cap assembly and case housing assy of rubber blanket 4.As shown in Figure 5, rubber blanket 4 surroundings have 2 circular convex tendons, cover after case lid, and this 2 road convex tendon pressurized, forms 2 sealing surfaces.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
