The invention discloses a switching structure, relates to the technical field of spaceflight power final assembly design, and aims to solve the problem that a profile spectrum damper and a profile spectrum storage tank are not easy to directly match and mount. According to the switching structure, a first through hole and a second through hole which are coaxially and fixedly connected with a mounting hole of a storage box lug piece are formed in a switching piece, and the first through hole and the second through hole are formed in a spaced mode; the two vibration reduction pieces are both coaxial with the second through hole, and the two vibration reduction pieces are oppositely arranged at the two ends of the second through hole correspondingly. A groove is formed in the mounting frame, a third through hole coaxial with the second through hole is formed in the bottom of the groove, and the adapter is located in the groove; and the fastening piece sequentially penetrates through the third through hole, one vibration reduction piece, the adapter piece and the other vibration reduction piece and is used for connecting and fixing the adapter piece, the vibration reduction pieces and the mounting frame. The first through hole and the second through hole of the adapter piece are respectively connected with the lug piece of the storage tank and the vibration reduction piece, and then the vibration reduction piece, the adapter piece and the mounting frame are fixedly connected through the fastening piece, so that the storage tank and the vibration damper can be indirectly assembled.
本发明公开一种转接结构,涉及航天动力总装设计技术领域,以解决型谱化减振器与型谱化贮箱不易直接匹配安装的问题。转接结构包括:转接件设有与贮箱耳片的安装孔同轴固定连接的第一通孔和第二通孔,第一通孔和第二通孔间隔设置;两个减振件均与第二通孔同轴设置,且两个减振件分别相对设于第二通孔两端;安装架设有凹槽,凹槽底部设有与第二通孔同轴设置的第三通孔,转接件位于凹槽内;紧固件依次穿过第三通孔、其中一个减振件、转接件以及另一个减振件,用于连接固定转接件、减振件与安装架。通过转接件的第一通孔和第二通孔分别连接贮箱的耳片和减振件,再通过紧固件将减振件、转接件和安装架固定连接,使得贮箱和减振器能实现间接装配。
