The invention discloses a soft resistance type door frame which comprises an inner door frame and an outer door frame which are movably connected, a cavity is formed between the inner door frame and the outer door frame, a limiting block and a soft resistance block which are in selective contact connection are arranged in the cavity from bottom to top, the limiting block is detachably connected with the outer door frame, and the soft resistance block is detachably connected with the inner door frame. The soft stop block and the limiting block are additionally arranged between the inner portal frame and the outer portal frame, so that the portal frames are effectively buffered during lifting, and the impact noise is reduced. The impact force borne by the limiting shaft sleeve when the lifting oil cylinder stretches out and draws back is relieved through the buffering function of the portal frame, and the oil leakage situation of the oil cylinder is reduced. The convex block with the upward inclined surface is matched with the fixed block to fix and support the soft resistance block, the side edge of the fixed block is hung on the convex block, and when the limiting block falls, the fixed block serves as a main stress piece, so that the structural stability is improved.

    本发明公开了一种软阻型门架,包括活动连接的内门架和外门架,内门架与外门架之间形成一空腔,所述空腔中由下而上设有选择性接触连接的限位块和软阻块,其中,所述限位块与外门架拆卸式连接,所述软阻块与内门架拆卸式连接。本发明通过在内门架和外门架之间增设软阻块和限位块,使门架起升时得到有效缓冲,减少撞击噪音。通过门架自身的缓冲功能减轻升降油缸在伸缩时限位轴套受到的冲击力,减少油缸漏油的情况。通过具有向上倾斜斜面的凸块与固定块相配合,对软阻块进行固定支撑,固定块侧边挂在凸块上,当限位块下落时,固定块作为主要的受力件,提高结构稳定性。
