Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Wherein identical label all refers to identical component in attached drawing.
In addition, if the detailed description of known technology for show the utility model be characterized in it is unnecessary, then by it
It omits.It should be noted that word "inner" and "outside" refer respectively to the direction towards or away from geometric center of specific component.
Embodiment 1
As shown in Figs. 1-2, the utility model provides a kind of multi-level safety type telescopic cover, including flexible cover main body 1, telescopic cover
The two sides of main body 1 are provided with telescopic cover side baffle 2, and flexible cover main body 1 is internally provided with several expansion plates 5, expansion plate 5
Outside is provided with several hangnail bars 6, is provided with several fasteners 3 on flexible inner wall of the cover main body 1 far from 5 side of expansion plate, blocks
The side of fastener 3 is provided with several round holes 4, and cushion 7, the inside of cushion 7 are provided on the inner wall of telescopic cover side baffle 2
It is provided with ball 8, and ball 8 is between cushion 7 and expansion plate 5.
Further, round hole 4 is to snap connection with hangnail bar 6, and when expansion plate 5 is unfolded, hangnail bar 6 penetrates round hole
It in 4, is tipped upside down on outside round hole 4 using hangnail, plays fixed function.
Expansion plate 5 and flexible cover main body 1 are to be slidably connected, by the ball 8 of 7 inside of cushion, make expansion plate 5 reduce with
