The specific embodiment

Now in conjunction with the accompanying drawings, this utility model is described in further detail:

Multifunctional hospital bed and the stretcher convertible car of a kind of folding as shown in Figure 1 comprises a body 8, guardrail 7, castor mechanism 1, drip stand assembly 11, footpost jack, bed board elevating mechanism and bed board slipping mechanism.

Bed body 8 is steel construction piece as carrier, and its front end is provided with directive wheel 4.

Described footpost jack is installed on a body 8 times and is supported by described castor mechanism 1, two groups of jacks before and after comprising, every group of jack comprises

trip rod

3 and 13,

lock rope

5 and 12, straight lower limb bar 2 and 6 respectively, goes up connecting rod 14, lower link 16, coupling assembling 15 and safety pin;

Preceding trip rod 3 is articulated in the front portion of a body 8, and back trip rod 13 is articulated in the middle part of a body 8;

Described coupling assembling 15 comprises two hinged connectors up and down, and respectively as shown in Figure 3 and Figure 4, described connector up and down is tube-in-tube structure, and is provided with the pin-and-hole of assigning safety pin;

Safety pin is with spring outward; Last connecting rod 14 and lower link 16 are socketed on respectively in the connector up and down of described coupling assembling 15 by coupling assembling is hinged and realize folding and unfolding, and when being positioned at linear position, upper and lower connecting rod constitutes the dead-centre position, the other end of last connecting rod 14 is hinged with bed body 8, and the other end of lower link 16 is hinged with straight lower limb bar 2; Described lock rope 5 is connected with 13 with trip rod 3 respectively with an end of 12, and the other end respectively has two leaders, is connected with last connecting rod with safety pin respectively;

Rescuing the scene, when described folding multifunctional hospital bed with stretcher convertible car when being used to transport the wounded or patient, described footpost jack is in and puts down holding state, when car body will be gone up ambulance, trip rod 3 is collided with ambulance before described, the front brake rope 5 that links with preceding trip rod 3 is pulled, then the safety pin that links with front brake rope 5 is drawn out from coupling assembling 15, removed the locking state of foreleg jack, last connecting rod 14 continues to be pulled, so upper and lower strut breaks away from the dead-centre position, the foreleg jack is packed up; When the foreleg jack was packed up, back trip rod 13 was clashed into by the foreleg jack, and pulling back brake rope 12, packed up and moved and pack up so the back leg jack takes place as the foreleg jack is same, and then car body enters ambulance smoothly;

When car body shifted out in ambulance, back leg jack and foreleg jack successively shifted out in ambulance, and after falling under action of gravity, safety pin enters in the pin-and-hole of coupling assembling under spring action, and upper and lower strut is locked in the dead-centre position.

So, the footpost jack adopts mechanism's dead-centre position self-locking and safety pin location double protection method, can guarantee the stretcher stability of neutralization during as interim sick bed of advancing, and guarantees patient's safety.

Castor mechanism 1 has can locate locked device, do not need to move when maybe must keep the stretcher transfixion to serve as examinating couch with the stretcher convertible car when described folding is multifunctional hospital bed, can stuck castor, it can not touched, be convenient to the inspection of doctor to patient.

Described bed body elevating mechanism as shown in Figure 2, comprises leading screw 22 and two nuts 211 and 212 of two groups of non-slippage brackets 171 and 172, one groups of slippage brackets 19, axis 25, spout 24, crossbar telescoping mechanism 23, band handwheel;

Described two groups of non-slippage brackets 171 and 172 1 ends are hinged with bed body 8 respectively, and the other end is then hinged with slide plate frame 18 respectively;

Described crossbar telescoping mechanism 23 is made of the cross-articulation rod member, and rod member end and two nuts 211 and 212 that are enclosed within on the leading screw 22 are hinged, two nuts 211 and 212 with leading screw two screw thread pairs of 22 formation and opposite spin; The other end of crossbar telescoping mechanism 23 is connected in the groove of spout 24 by pin; Described spout 24 is fixedly connected with axis 25 and is intersecting the longitudinal sliding motion of telescopic action lower edge bed body 8 of telescoping mechanism 23; Described slippage bracket 19 1 ends are hinged with nearly slide plate frame 18 ends of the non-slippage bracket 172 of vicinity, and the other end and axis 25 are hinged;

The height of the multifunctional hospital bed bed body with the stretcher convertible car of described folding can be regulated to adapt to different sick bed height by the bed board elevating mechanism: described elevating mechanism mechanism adopts manual operation, rotate handwheel 20 and drive leading screw 22 rotations, nut 211 on it, 212 in opposite directions or opposing move, then correspondingly extend or shrink with nut 211 and 212 hinged crossbar telescoping mechanisms 23, and push-and-pull axis 25 slides along bed body 8, then slippage bracket 19 is done corresponding the slip and spinning movement, do spinning movement with the non-slippage bracket 172 that slippage bracket 19 is hinged thereupon, then slide plate frame 18 is supporting slippage the bed board 10 raised or landing on it, and another non-slippage bracket 171 then cooperates the corresponding spinning movement of generation thereupon.

Described slipping mechanism comprises slide plate frame 18, slide rail 9, slide block 91 and slippage bed board 10 from bottom to up, described slide plate frame 18 and slippage bed board 10 are parallel to a body 8 respectively, slide rail 9 forms a pair of sliding pair with slide block 91, slippage bed board 10 is laterally moved along slide plate frame 18, slide rail 9 is fixedly linked on the slide plate frame 18, and slide block 91 is fixedly linked on the slippage bed board 10;

Described folding is multifunctional hospital bed can realize that by the bed board slipping mechanism transverse horizontal moves with the stretcher convertible car.

To sum up, described folding multifunctional hospital bed with the stretcher convertible car, adopt manual actuation, promptly realize advancing of stretcher smoothly, ambulance and patient are by stretcher mobile to sick bed, examinating couch, operating-table up and down.

For avoiding patient to fall from bed because of carelessness, stretcher is equipped with guardrail 7, and is furnished with the rotary extension of installation drip stand assembly 11.

The above; it only is the preferable specific embodiment of this utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
