Rotation；The rotation of second gear rotation driven gear axis；Gear shaft rotation drives first gear rotation；First gear rotation will make
It is mobile towards the side for being equipped with the first gag lever post to obtain the first rack gear；In the first rack gear moving process, when on the first rack gear
When the upper-end contact of the second escape groove and the first gag lever post, the first rack gear just loses the constraint to the first gag lever post, first
In rack gear moving process, when the triggering corner block on the first rack gear is contacted with the trigger board being mounted on the first gag lever post, the
One rack gear movement will drive the first gag lever post to move up by triggering corner block and trigger board, and the first gag lever post moves up
Guide rail shell is driven to move up, guide rail shell, which moves up, drives driving plate to move up, and driving plate moves up drive drive rod
Move up, drive rod move up drive drive block move up, drive block move up drive limited block be upwards it is mobile,
During limited block moves up, when limited block is moved fully in square groove, limited block just loses to be folded to first
The constraint of bar and the second folding rod, the first folding rod and the second folding rod can relatively rotate at this time；First folding in the present invention
One end of folded bar is mounted on the periphery of first support bar by revolute pair, can be between the first folding rod and first support bar
Mutually swing；One end of the second folding rod is mounted on the downside of support plate by revolute pair in the present invention, and the second folding rod can be with
It is swung relative to support plate；The effect for being mounted on the leaf spring between the second folding rod and support plate is played back to the second folding rod
Position effect；The effect of guide rail shell is that connection function, another aspect guide rail on the one hand can be played to the first gag lever post and drive rod
Shell will not interfere during moving up with shaft is connect；The effect of return spring is to play return to limited block and make
With when the first folding rod and the second folding rod turn again to original state, under the action of the return spring, limited block can be with
Position-limiting action is played to the first folding rod and the second folding rod again；The effect for the first escape groove opened in support plate is to prevent
First gag lever post is interfered in moving process with support plate；Hinged block can be swung relative to support plate, i.e., the first gag lever post can
To swing relative to support plate, effect is to prevent the first gag lever post and support plate from interfering；The diameter of first gear in the present invention
Less than the diameter of second gear；Its effect is to play the role of deceleration torque increase.
The first trunnion is mounted on the downside of support plate in the present invention；Second support bar passes through two the second trunnions and connecting shaft
With the downside for being fitted to support plate of the first trunnion；The lower end of second support bar is equipped with second universal wheel；Third
One end of folding rod is mounted on the periphery of second support bar by revolute pair；Pacified by revolute pair one end of 4th folding rod
Mounted in the downside of support plate；The other end of the other end of third folding rod and the 4th folding rod is connected by revolute pair；Four fold
Leaf spring is installed between folded bar and support plate；In the guide groove that triggering guide block installation is opened on the supporting plate, guide block and guide groove are triggered
Top end holder equably install there are five reset spring；The upper end of first frizzen is mounted on the downside of triggering guide block one end；
In the sliding square groove that the upper end installation of second frizzen is opened on the supporting plate；Triggering square is mounted under the second frizzen
End；Spring mounting ring is mounted on the second frizzen；First spring is installed between spring mounting ring and the downside of support plate；
One end of second gag lever post is provided with pilot hole；Second gag lever post is mounted on the second frizzen by pilot hole；Second gag lever post
The other end pass through the installation square groove opened in the square breach and connecting shaft opened on the second trunnion；Spring mounting blocks are mounted on
On second gag lever post；Second spring is installed between spring mounting blocks and the first trunnion；It triggers square and is mounted on the first support
The second universal wheel cooperation on bar；First frizzen cooperates with the second universal wheel being mounted in second support bar；When triggering side
When the block thrust upward by the second universal wheel being mounted in first support bar, triggering square will be moved；Square is triggered to move
It is dynamic just to will drive the movement of the second gag lever post；In the second gag lever post moving process, when what is opened on the second gag lever post and connecting shaft
When installation square groove completely disengages, the second gag lever post just loses the limit to the first trunnion and the second trunnion, i.e. second support bar
It can be swung relative to support plate；As soon as the first frizzen will drive touching when the first frizzen is by upward thrust
Hair guide block moves up；Triggering guide block, which moves up, will to trigger guide block and the second frizzen disengages；At this time in the first bullet
Under the action of spring, the second frizzen will be moved up, and the second frizzen moves up drive triggering square movement, so that triggering
Square is disengaged with the second universal wheel being mounted in first support bar being in contact with it；Prevent second support bar during return
Because the second universal wheel being mounted in first support bar influences its recovery；The effect of second spring is limited second in the present invention
Position bar plays the role of return, so that the first trunnion and the second trunnion are when being restored to original state, the second gag lever post is in the second bullet
It can continue to play position-limiting action to the first trunnion and the second trunnion under the action of spring；The effect of reset spring is pair in the present invention
Triggering guide block plays the role of return.
Relative to traditional medical manipulator technology, the medical stretcher Folding trolley that the present invention designs passes through gear and rack gear
Transmitting is so that the traveling wheel and bracket of cart realize folder function；So that cart when being moved on ambulance, passes through two
One universal wheel can reduce the vibration of cart, while be made by two the first universal wheels triggering first support bars and second support bar
It obtains first support bar and second support bar realizes folder function, and when cart is moved to ground from ambulance, in leaf spring
Under effect, the traveling wheel and bracket of cart can successively restore；So that cart is more convenient in use.
