A mounting hole is formed on steel plate, the position of corresponding positioning plate is formed with jack around mounting hole, and positioning plate insertion is inserted
The position of fixed card buckle in hole.
Moreover, the skeleton is by 5~6mm of width, height 8~9mm, 1~1.5mm of the distance between bone tooth.
Moreover, the opening size of two claw-plates is 15~18mm, 8~10mm of each claw-plate width.
Moreover, the distance between forward and backward anticreep baffle is 8~10mm, 3~5mm of barrier width.
Moreover, the distance between left and right anticreep baffle is 15~20mm, 5~10mm of barrier width.
The utility model has the beneficial effects that
1, the high filling-foam material of microskeleton on the inside of automobile A column provided by the utility model, combines exoskeletal filling material
And have skeleton fill material the advantages of, itself be also provided with areola place foaming the advantages of, have biggish market potential.
2, in the utility model EVA foaming layer compound upper microskeleton fish bone well skeleton structure so that it is more firm to grab relay, no
It is easy to fall off.The injection molding of fish bone well skeleton is simple, so that die cost substantially reduces.
3, the utility model has devised new-type buckle structure simultaneously, and forward and backward anticreep baffle prevents material from hanging, left,
Right anticreep baffle plays position-limiting action, so that EVA foamed board will not fall off when high temperature foams.
4, automobile A column internal cavity is passing through 20-30min, after 150-210 DEG C of high-temperature baking, after EVA foaming layer is foamed
It is sticked on the inside of A column on steel plate, is closely combined into one, cavity passage barrier is effectively reached hermetically sealed, so as to improve
The purpose of interior sound insulation vibration and noise reducing.
