Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides the knee protection device that as Figure 1-3 a kind of avoids car crass, including protection
Device body 1 and fixed mount 3, the both sides of the protection device body 1 are fixed with bearing pin 2, and bearing pin 2 is fixed with fixed mount 3 and connected
Connect, the end of the fixed mount 3 is fixedly connected with air pump body 4, and the protection device body 1 includes shell 5 and inner casing 7, institute
Inner casing 7 is stated to be arranged on inside shell 5, and the two ends of inner casing 7 are fitted and connected with shell 5, inwall and the inner casing 7 of the shell 5
Outer wall is fixedly connected by damping device 6.
Further, the shell 5 and inner casing 7 are the matrix that almag is made, and shell 5 and inner casing 7 are fan
Type, 1/3rd of the diameter of a diameter of shell 5 of the inner casing 7, and the interior survey interval of inner casing 7 is pasted with rubber sheet gasket.Can be with
The hardness and non-deformability of protection device body 1 are improved while being effectively protected knee.
Further, the damping device 6 is angularly at least provided with five groups, and the damping device 6 includes the outer He of loop bar 61
Connecting rod 62, one end of the connecting rod 62 is stretched into and piston plate 63 is fixedly connected with inside outer loop bar 61, the piston plate 63
