Shown in Figure 20, lock device is hollow structure, and fixed in the inner cavity of lock device there are two the third fixed plates being symmetrical set
533, being also slidably installed in the inner cavity of lock device, there are two the third slide plate 531 being symmetrical set, third slide plate and thirds
Fixed plate corresponds.Third spring 532 is equipped between corresponding third slide plate and third fixed plate, it is sliding in each third
The second lock pin 52 is respectively fixed on plate, the second lock pin is successively pierced by lock device, by back under the action of third spring
Circular hole after stretch out backrest, circular hole setting is corresponded by back and with the second lock pin.Divide on every one second lock pin
It is not fixed with link 534, is set between two third fixed plates there are two directive wheel 535, directive wheel and lock device are rotatablely connected,
It is respectively to have the second drawstring 54 on each link, the contacts-side-down of the second drawstring and directive wheel is equipped at the top of lock device
The avoid holes of the second drawstring are avoided, two second drawstrings pass through after avoid holes stretch out lock device and are bundled into one, as shown in figure 19, restricting
The upper end of slot is rotatably equipped with the second line wheel 56 by wheel shaft 561, and the second drawstring stretched out from lock device is fixed on the second line
On the outer wall of wheel.It is equipped with wind spring 562 between wheel shaft and backrest, is fixed with and is placed in by tergolateral knob 57 on wheel shaft.
When nature, the second drawstring is in straight condition but without pulling force.When turning knob, wind spring active force can be overcome
So that the second drawstring is wrapped in the second line wheel, the second drawstring bears pulling force at this time, pulls two the second lock pins close to each other,
So that the second lock pin is removed from second location hole, the backrest of lying status can be started at this time.After unclamping knob, in wind spring
Under the action of the second line wheel reset, the second lock pin reset.To be further oriented to the second drawstring, if being equipped in rope groove
Dry guide ring 58, the second drawstring is placed in the inside of guide ring, to avoid the sideslip of the second drawstring.State that there are two types of backrests, one
It is lying status, second is that heeling condition;When patient is sitting on buttocks support panel, when backrest is in heeling condition;When patient's recumbency,
Backrest is in lying status.To be equipped with handle 59 at the back side of backrest, when backrest lies low, handle is placed in convenient for pushing moving bed
In handle slot.Knob, the second line wheel, the second drawstring, third slide plate, third fixed plate, third spring and the second lock pin are constituted
Backrest lockable mechanism.
As shown in Figure 10, it is fixed with two pairs of vertical plates 6 at the top of buttocks support panel, is equipped with handrail in the top of pairs of vertical plate
61, connecting rod 62 is equipped between handrail and vertical plate.Sponge is wrapped up outside handrail.Third is respectively equipped on two vertical plates on right side
Location hole 63 forms obtuse angle angle when the second lock pin is extend into third location hole between backrest and buttocks support panel, this
When backrest and buttocks support panel it is relatively fixed.Second, third location hole is located at using backrest hinge joint as on the circumference in the center of circle, can be with
Multiple third location holes positioned at different location are set on vertical plate, in order to adjust the tilt angle of backrest.
To guarantee comfort when sitting or recumbency, it is equipped with stern pad 7 on buttocks support panel, is equipped in thigh support board
Leg pad 71 is being equipped with back pad 73 by back, and transition pad 72 is equipped between leg pad and stern pad, and transition pad has elasticity well,
It can according to need and elongate or shorten.Transition pad is preferably also provided between stern pad and back pad.
Need to patient carry out neurosurgery when, allow patient to be sitting on moving bed first, be then pushed into patient
In operating room;Then, moving bed is pushed into the top of pedestal, the separation of supporting leg is then driven by supporting leg driving mechanism, so that
Moving bed falls until the positioning plate on moving bed is placed in locating slot;During moving bed is transferred to above pedestal, leg
After support plate and base contacts, thigh support board clockwise oscillation;And after positioning plate is placed in locating slot, thigh support board position
It is contacted in the horizontal plane and lower surface of thigh support board with base upper surface.Then rotate knob so that the second lock pin from
It is stretched out in third location hole, then slowly puts down backrest, until backrest and base contacts, can unclamp knob, the second locking at this time
Pin, which protrudes into, realizes locking in second location hole;Finally, disinfect box is pulled out from square groove, and realized by upper pendulum bar lockable mechanism
To the locking of disinfect box, it is spare to extract sterilization pipe out.
