The volume support folding storage working principle of auxiliary bracket:
By taking the unfolded state of the volume support 28 of Fig. 2 becomes the 28 folding storage state of volume support of Fig. 1 as an example:
Unscrew a pair of of lift telescopic bolt 263 first, such lift telescopic bar 27 is in free state, then unscrews flexible
Bolt 243 is connected, bar 25 is telescopically connected in this way and is in free state, and connect being telescopically connected to bar 25 and inwardly plugging until flexible
Extension bar 25 contradicts the bottom for arriving center telescopic chute 240, then tightens and be telescopically connected to bolt 243, is telescopically connected to bar 25 in this way and fixes again,
Then make lift telescopic bar 27 parallel with bar 25 is telescopically connected to, then tightening a pair of of lift telescopic bolt 263, lifting in this way is stretched
Contracting bar 27 keep be telescopically connected to 25 parastate of bar, then pull back upside center telescopic block limit plate 235, in this way in
Heart telescopic block 24 is in free state, and then center telescopic block 24 is rotated by 90 ° and moves down along telescopic chute 230, herein
In the process, the center telescopic block limit plate 235 for decontroling upside pulls back the center telescopic block limit plate 235 of downside, works as center
When telescopic block 24 reaches the bottom of telescopic chute 230, the center telescopic block limit plate 235 of downside, such center telescopic block 24 are decontroled
It is limited by the center telescopic block limit plate 235 of downside, then finally pulls back flexible limit connecting plate 234, such telescopic seat
23 are in free state, and telescopic seat 23 is then become vertically downward state from state straight up, decontrol flexible limit at this time
Connecting plate 234, telescopic seat 23 are limited again, complete 28 folding of volume support for becoming Fig. 1 from the unfolded state of the volume support 28 of Fig. 2 in this way
The process of folded receiving state will not cause to oppress, be conducive to the smooth of galvanometer at this time due to not having the presence of volume support 28 to patient
It carries out.
The above content is only better embodiment of the invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to this hair
Bright limitation.
