Description

Trolley for hospital use

This utility model relates to a kind of medical care equipment.

In the prior art, critical patient in the hospital and paralytic, sometimes need to send operating room or the treatment of other section office with them or check, what use at present is a kind of go-cart of normal tape wheel, this go-cart can not be adjusted height, can not translation, and need 2--4 stout man that patient is lifted from sick bed during use, be put into then in the go-cart, again patient carried off after treatment finishes.This is not only heavy, and causes suffering to patient.

The purpose of this utility model provide a kind of can be easily and transfer patient's equipment painlessly.

For achieving the above object, this utility model mainly comprises bed surface, upper rail, roller, lower guideway, carriage, vehicle frame, wheel, guiding mechanism and elevating mechanism composition.Vehicle frame is the framework of a cuboid, wheel be installed in vehicle frame below.Carriage is a rectangular frame, it by guiding mechanism and elevating mechanism be installed in vehicle frame above, and can on vehicle frame, raise or reduce.Be welded with two lower guideways above the carriage, on two lower guideways, respectively lay two rollers.Bed surface is a rectangular flat, is welded with two upper rails below bed surface, and upper rail is placed in the groove of roller.

Elevating mechanism can be made up of screw mandrel, nut, one pair of conical gear, gear shaft, crank and bearing; Conical gear center have a through hole and and nut combine as a whole, they are installed on the vehicle frame by bearing together, screw mandrel is installed on the vehicle frame by nut and bearing, another conical gear is installed on the gear shaft, gear shaft is installed on the vehicle frame by two bearings, crank is installed in the gear the tip of the axis, the conical gear rotation drives the nut rotation when rotating crank, thereby screw mandrel is risen or decline, because an end of screw mandrel withstands on the carriage, so carriage and bed surface are all along with rising or descending.

Elevating mechanism can also be the hydraulic jack at installation vehicle frame middle part, and the push rod head of jack withstands on the carriage, and when the depression bar of continuous pressure jack, push rod rises, with carriage and bed surface jack-up, and when unclamping valve, push rod decline carriage and bed surface landing.

Guiding mechanism can be made up of four guide rods and four sliding sleeves, and four guide rods are welded on four angles of vehicle frame, and four sliding sleeves are welded on the relevant position at four angles, carriage below, and four sliding sleeves are enclosed within respectively on four guide rods.Whole carriage and bed surface can move along guide rod is upper and lower.

Guiding mechanism can also be made up of four guide rods and four directive wheels, and four guide rods are welded in respectively on four angles of vehicle frame, and four directive wheels are fixed on respectively on the relevant position at four angles, carriage below, and guide rod is embedded in respectively in the groove of directive wheel.

Bed surface along continuous straight runs mobile is by using the hand push bed surface, makes roller roll and realize along upper rail and lower guideway.Also can below bed surface, fix a nut, the screw mandrel along continuous straight runs that matches with nut is fixed on the carriage, install crank at the end of screw mandrel.When with the crank rotary screw rod, drive bed surface and do the transverse horizontal motion by nut.

Adopted technique scheme, owing to carriage is installed on the vehicle frame by guiding mechanism and elevating mechanism, so carriage and bed surface together can be in the guide rod liftings of the manipulation lower edge of elevating mechanism.Because bed surface is placed on roller and the guide rail, so bed surface can move horizontally along guide rail.During use trolley for hospital use is pushed into the sick bed next door, with elevating mechanism levelling bed surface height, makes it consistent earlier with the sick bed height.Again bed surface is pushed away and cause a disease the person down, treat that patient stands up to sleep after on the bed surface, again bed surface and patient are pushed back on the vehicle frame.Thereby easy to use and patient's no pain.

Below in conjunction with drawings and Examples this utility model is further described:

Fig. 1 is the front view of trolley for hospital use.

Fig. 2 is the left view of trolley for hospital use, and Fig. 1 and Fig. 2 all adopt the structure diagram mode.

Fig. 3 is that elevating mechanism adopts jack, and guiding mechanism adopts the structure diagram of the wheeled trolley for hospital use of guiding.

Medical go-cart is made up of bed surface 1, upper rail 2, roller 3, lower guideway 4, carriage 5, pallet 6, bearing 7, screw mandrel 8, conical gear 9, crank 10, sliding sleeve 11, guide rod 12, wheel 13, vehicle frame 14, nut 15, conical gear 16, plane bearing 17, bearing 18, gear shaft 19 in Fig. 1 and Fig. 2.Vehicle frame 14 is frameworks of a cuboid, wheel 13 be installed in vehicle frame 14 below.On four angles of vehicle frame 14, vertically be welded with 4 guide rods 12.Carriage 5 is rectangular frames, is welded with 11, four sliding sleeves 11 of four sliding sleeves on four angles below it and is enclosed within respectively on four guide rods 12, and whole carriage 5 can rise or descend along guide rod 12.On carriage 5, be welded with two tubulose lower guideways 4, laid the roller 3 of two troughs of belt on every lower guideway 4.Bed surface 1 is a rectangular flat, is welded with two upper rails 2 below the bed surface 1, and bed surface 1 and upper rail 2 are placed on the roller 3 together, and upper rail 2 is embedded in the groove of roller 3.Elevating mechanism is made up of pallet 6, bearing 7, screw mandrel 8, conical gear 9, crank 10, nut 15, conical gear 16, plane bearing 17, two bearings 18, gear shafts 19.There is the through hole of the big what screw mandrel of a diameter external diameter at the center of conical gear 16, and nut 15 and conical gear 16 are coupled to each other and keep rotation synchronously.Nut 15 is installed on the vehicle frame 14 by plane bearing 17.The hole that one end of screw mandrel 8 passes conical gear 16 centers screws in the nut 15, and the other end is installed on the vehicle frame 14 by bearing 7.The conical gear 9 that is meshed with conical gear 16 is installed on the gear shaft 19, and gear shaft 19 is installed on the vehicle frame 14 by two bearings 18, and crank 10 is installed in the end of gear shaft 19.

Rotate crank

10,9,16 rotations of gear shaft 19 drive conical gears, thus drive nut 15 rotations, owing to nut 15 is fixed on the vehicle frame 14, so screw mandrel 8 promptly makes progress or motion down, with carriage 5 upwards jack-up or declines.Because bed surface 1 is placed on the carriage 5, so bed surface 1 is also along with rising or descending.The effect of pallet 6 is to protect the bottom surface of carriage 5 not by the screw mandrel bursting.

The moving horizontally of bed surface 1 can be directly bed surface 1 with hand push and be rolled by roller 3 on lower guideway 4 and realize, also can below bed surface 1, fix a nut, along continuous straight runs installs and fixes a screw mandrel with matching on carriage 5, the screw mandrel end is installed crank, rotate crank, bed surface 1 is moved horizontally at the drive lower edge of nut guide rail.

The difference of trolley for hospital use shown in Figure 3 and Fig. 1, trolley for hospital use shown in Figure 2 is, the hydraulic jack that the elevating mechanism of trolley for hospital use shown in Figure 3 has adopted the general repair automobile to use, it is installed on the vehicle frame 5, the push rod head of jack withstand on carriage below, by the height of the reduction of push rod head control bed surface 1.In addition, guiding mechanism is formed by being welded in four guide rods 12 on 14 4 angles of vehicle frame and being installed in carriage 5 following directive wheels 20, cut gathering sill on the face of cylinder of directive wheel 20, guide rod 12 is stuck in the groove of directive wheel, when carriage 5 liftings, directive wheel 20 rolls on guide rod.

This utility model can also have many variations except said structure.The kind of drive of side such as elevating mechanism can also adopt the worm and gear transmission, gear, wheel bar transmission and chain transmission etc., and all these variations all belong to protection domain of the present utility model.
