The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, the device comprises an outer shell, an inner shell, a fixed column, a shielding layer, a filler, an anti-prick filler, an upper movable plate, a lower movable plate, a movable column, a sleeve, a telescopic rod, a compression spring, a guide part and a fixing column, wherein the outer shell is 1, the inner shell is 2, the inner shell is 3, the fixed column is 4, the shielding layer is 5, the anti-prick filler is 6, the upper movable plate is 7, the lower movable plate is 8, the movable column is 9, the sleeve is 10, the telescopic rod is 11.
Detailed Description
As fig. 1 is the utility model discloses a structural schematic diagram, a novel MPP power protection tube, including shell 1 and the inner shell 2 of setting in shell 1 inside, be provided with the fixed column 3 of being connected with inner shell 2 on the shell 1 inner wall, the 2 outside of inner shell is provided with shielding layer 4, is provided with between shell 1 and the inner shell 2 and prevents stinging stopping 5, is provided with the movable plate group who connects through elastic mechanism in the inner shell 2, and the movable plate group includes fly leaf 6 and lower movable plate 7, and the symmetry is provided with movable post 8 on the 6 bottom surface limit portion of last fly leaf, and the symmetry is provided with the sleeve pipe 9 that agrees with movable post 8 on the 7 bottom surface limit portion of lower movable plate. The utility model discloses a set up the protection tube and prevent that thorn stopping 5 can improve the protective capability of protection tube to power cable with shell 1 and inner shell 2 and setting, through the movable plate group that elastic mechanism connects, make the protection tube can be applicable to the power cable of variation in size, improved the commonality of power cable protection tube, enlarged the application scope of power cable protection tube, reduced the manufacturing cost who makes many sets of power cable protection tube, break away from when can preventing the power cable installation through movable post 8 and sleeve pipe 9's cooperation.
Three fixing columns 3 are evenly arranged on the inner wall of the shell 1. The shielding layer 4 is made of a semiconductor insulating shielding material. The stab-resistant filling material 5 is made of high-molecular polyethylene and aramid fiber. The elastic mechanism comprises a compression spring 11 sleeved on a telescopic rod 10, one end of the telescopic rod 10 is connected with the inner wall of the inner shell 2, and the other end of the telescopic rod 10 is connected with the movable plate group.
