Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail。
See Fig. 1, Fig. 2, during free state, this utility model includes buffering guiderod 1, buffering nut 2, buffer spring cylinder 10,4, two grades of floating springs 7 of elastomer, one-level floating spring 8 and cushions little nut 11, buffering nut 2 and buffer spring cylinder 10 are threadably secured connection, buffering guiderod 1 is installed in the inner chamber of buffer spring cylinder 10 and buffering nut 2 formation, buffering guiderod 1 right-hand member is equipped with the little nut 11 of buffering and buffer spring cylinder 10 right-hand member minor diameter fit, equipped with elastomer 4 on the left of the buffering guiderod 1 in buffer spring cylinder 10；Elastomer 4 and cushion between little nut 11, one-level floating spring set 8 and two grades of floating springs 7 are nested to be installed on buffering guiderod, and one-level floating spring right-hand member protrudes from two grades of floating springs；Being provided with step in buffer spring cylinder, two grades of floating springs are limited in the step on the interior right side of buffer spring cylinder 10；One-level floating spring 8 is limited in the little nut of buffering。
See Fig. 3, Fig. 4, during back seat: large washer 3 is spacing by buffer spring cylinder and buffering nut 2 step, buffering guiderod 1 drives and cushions little nut 11 to left movement, compression one-level floating spring 8, cushions little nut 11 and drives big spring set 9, compress two grades of floating springs 7 when continuing motion, when continuing motion, big spring set 9 withstands big spring protheca 6, continues compresses elastomeric 4, it is achieved repeatedly cushion。
See Fig. 5, Fig. 6, during preshoot: buffering guiderod 1 drives large washer 3, spring set 5, big spring protheca 6 to move right, compress two grades of floating springs 7, after big spring protheca 6 contacts with big spring set 9, can not move to the right at buffer spring cylinder 10 owing to big spring overlaps 9, when buffering guiderod 1 continues to move right, buffering guiderod 1 drives large washer 3 to continue compresses elastomeric 4, it is achieved repeatedly cushion。
Bidirectional buffering is achieved by this utility model device。
