Description
Technical field
This utility model relates to a kind of armarium, particularly relates to a kind of lifting hospital bed for lifting invalid bed.
Background technology
In armarium, the altitude mixture control of medical bedstead is the diagnosis coordinating medical treatment.Be imaging system below medical bedstead in X-ray equipment, above medical bedstead, hang bulb drive system.The center of bulb system is corresponding with the center of imaging system.At present, in the medical bedstead regulating height, great majority adopt the lifting of scissor-type principle, and the method for electric push rod lifting.In these two kinds of methods, because multiple action to make in motion accumulated error strengthen, and the irregular feeding of dynamical system makes sick bed can produce in lifting process to tremble and send certain noise, and mostly sick bed is that when moving non-uniform movement is elevated.Now patient is very uncomfortable in bed, the patient that especially state of an illness is comparatively special, as heart disease and orthopedics patient can aggravate disease.
Utility model content
The technical problems to be solved in the utility model be to provide a kind ofly to be elevated steadily, noise is little, the lifting hospital bed that can adapt to various patient.
A kind of lifting hospital bed of this utility model, the rectangular frame that the crossbeam comprising bedstead and about two placements of being placed by two front and back forms, two bedsteads are provided with the leading screw of horizontal positioned in left-right direction, synchronous rotary mechanism drives two leading screw common rotation, two ends, described leading screw left and right are processed with the contrary screw thread of rotation direction, screw thread arranged outside has female first bearing of band, described bedstead is also provided with feed rod, described feed rod and leading screw are that left and right is set up in parallel, two ends, feed rod left and right are movably set with the second bearing, each first bearing and the second bearing are all hinged with bedrest, the movable end of two bedrests corresponding on same leading screw or feed rod is hinged to herringbone travel(l)ing rest by jointed shaft, four jointed shafts are provided with bed board, the first bearing on same bedstead on the correspondence position of left and right is connected by connecting rod with the second bearing.
A kind of lifting hospital bed of this utility model, the feed rod on wherein said bedstead and leading screw are that front and back be arranged in parallel.
A kind of lifting hospital bed of this utility model, wherein said bedstead two ends are provided with gripper shoe, and described gripper shoe is for supporting leading screw and feed rod.
A kind of lifting hospital bed of this utility model, wherein said synchronous rotary mechanism comprises two sprocket wheels, and described two sprocket wheels are arranged on the same side of two leading screws, and two sprocket wheels are by same chain-driving.
A kind of lifting hospital bed of this utility model difference from prior art is that a kind of lifting hospital bed of this utility model is provided with the contrary screw thread in direction at leading screw two ends, and is hinged with bedrest on the first bearing be threaded connection with leading screw.During screw turns, can move in the opposite direction with first toilet of leading screw two ends screw-threaded engagement, drive bedrest to swing in the opposite direction, thus change the height of jointed shaft between two bedrests, play the effect changing sick bed height.Two sprocket wheels drive two the first screw synchronous to rotate, and are connected with the second bearing by the first bearing by connecting rod, four pairs of bedrests can be made to be synchronized with the movement, ensure that sick bed operates steadily in the process of lifting.Synchronous motion stably simultaneously also effectively can reduce vibration during sick bed lifting, plays the effect reducing noise.
Below in conjunction with accompanying drawing, a kind of lifting hospital bed of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the axonometric chart (saving bed board) of a kind of lifting hospital bed embodiment 1 of this utility model;
Fig. 2 is the top view (saving bed board) of a kind of lifting hospital bed embodiment 2 of this utility model.
Detailed description of the invention
Embodiment 1, as shown in Figure 1, the rectangular frame that the crossbeam 7 that a kind of lifting hospital bed of this utility model comprises bedstead 10 and about two placements of being placed by two front and back forms.Two bedsteads 10 are provided with leading screw 9, and leading screw 9 is left and right directions horizontal positioned, and leading screw 9 is driven by synchronous rotary mechanism and is synchronized with the movement.Synchronous rotary mechanism comprises the same side that two sprocket wheels, 1, two sprocket wheels 1 are arranged on two leading screws 9, and by same chain-driving, to reach the effect of synchronous axial system.Leading screw about 9 two ends are processed with the contrary screw thread of rotation direction, and screw thread arranged outside has female first bearing 2, first bearing 2 of band can pass through rotation side-to-side movement on leading screw 9 of leading screw 9.Bedstead 10 is also provided with feed rod 5, feed rod 5 with leading screw 9 for left and right is set up in parallel.Feed rod about 5 two ends are movably set with the second bearing 8, second bearing 8 and can horizontally slip on feed rod 5.Each first bearing 2 and the second bearing 8 are all hinged with bedrest 3, need eight bedrests 3 altogether.The movable end of two bedrests 3 on same leading screw 9 or feed rod 5 is hinged to herringbone travel(l)ing rest respectively by jointed shaft 6, and form four groups of herringbone travel(l)ing rests altogether, now four herringbone travel(l)ing rests are arranged as rectangle.Four jointed shafts 6 are provided with bed board.The first bearing 2 same bedstead 10 being positioned at left side is connected by connecting rod 4 with second bearing 8 in left side, and first bearing 2 on right side is connected by connecting rod 4 with second bearing 8 on right side.Two the first bearings 2 drive two the second bearings 8 to move respectively by connecting rod 4.Bedstead 10 is also provided with gripper shoe 11, and gripper shoe 11 is for supporting leading screw 9 and feed rod 5.
Embodiment 2, as shown in Figure 2, difference from Example 1 is: the feed rod 5 on bedstead 10 and leading screw 9 be arranged in parallel for front and back.Now four herringbone travel(l)ing rests be arranged as parallelogram.Can make a kind of lifting hospital bed more compact structure of this utility model like this, volume is less.
The operation principle of a kind of lifting hospital bed of this utility model is as follows: chain-driving two sprocket wheel 1 synchronous axial system, sprocket wheel 1 drives leading screw 9 synchronous axial system, the first bearing 2 on leading screw 9 starts to carry out rectilinear motion due to screw-driven, and drives the bedrest 3 hinged with it to swing.Because leading screw 9 two ends hand of spiral is contrary, two first bearing 2 directions of motion therefore on same leading screw 9 are contrary.Simultaneously the first bearing 2 is connected with the second bearing 8 by connecting rod 4, is positioned at first bearing 2 of bedstead 10 the same side and the second bearing 8 for synchronously to move in the same way.When needs sick bed raises, two the first bearings 2 on same leading screw 9 are simultaneously to middle part motion, and two bedrests 3 upwards swing, and the position of its jointed shaft 6 raises gradually, and bed board also raises gradually; When needs sick bed reduces, two the first bearings 2 on same leading screw 9 are simultaneously to two lateral movements, and two bedrests 3 are to lower swing, and the position of its jointed shaft 6 reduces gradually, and bed board also reduces gradually.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from this utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that this utility model claims determine.
