Description
Technical field
The utility model relates to field of medical technology, are more particularly to a kind of diagnostic couch driving device.
Background technique
Diagnostic couch is the equipment lain or crouched for patient when doctor checks patient, and current existing diagnostic couch is generally adopted
With the lifting of electric pushrod driving bed, but electric pushrod generally requires to be customized this according to the demand of equipment leads to electric pushrod
Procurement cycle it is long and equipment price is higher, in addition, the structure of electric pushrod is compact, the included general function of motor of push rod
Rate is little, diagnostic couch can not be driven to go up and down at a relatively high speed.
Utility model content
In view of the deficiencies of the prior art, the utility model provides diagnostic couch that is a kind of cheap and can realizing fast lifting
Driving device.
To achieve the above object, the utility model provides following technical solution: a kind of diagnostic couch driving device, including bottom
Seat and bed board, are connected with two isometric swing arms in parallel between the pedestal and the bed board, the both ends of the swing arm respectively with
The pedestal and the bed board are rotatablely connected, and are fixedly connected with lead screw on the pedestal, are arranged with feed screw nut on the screw rod,
Connecting rod is hinged on the feed screw nut, the connecting rod and the separate one end of the feed screw nut and the swing arm are hinged, described
Lead screw is connected with power device, and power device is motor, and when motor operation driving lead screw rotation, lead screw rotation drives lead screw spiral shell
Mother moves axially along lead screw, and due to being connected with connecting rod between feed screw nut and swing arm, feed screw nut is mobile to push connecting rod band movable pendulum
Arm rotation, so that the height of bed board be driven to change therewith, two swing arms it is isometric and be parallel to each other be installed on the pedestal with
Between the bed board, so that bed board remains parallel state during lifting, bed board stress equalization runs smoothly.
Power of motor and guide screw lead are selected according to demand, be can control bed board lifting speed and are met design requirement, because
Motor and lead screw are all standard components, and purchase is convenient, can reduce cost of equipment, shorten procurement cycle, this driving device utilizes company
The translation of feed screw nut is converted to the rotation of swing arm by bar, to realize the lifting of bed board, structure is simple, it is low in cost and
The fast lifting of bed board can be achieved.
Further, the connecting rod and the middle part of the swing arm are hinged, if articulated position is too high, connecting rod needs are longer, compare
Waste materials, if articulated position is too low, connecting rod pushes swing arm harder, hinged with the middle position of swing arm, while meeting material saving
Material and labour-saving effect.
Embodiment one: the power device is servo motor.
Embodiment two: the power device is stepper motor.
In conclusion the utility model utilizes connecting rod, the translation of feed screw nut is converted into the rotation of swing arm, to realize
The lifting of bed board, this driving device structure is simple, fast lifting that is low in cost and can realizing bed board.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Mark explanation: 1, bed board；2, swing arm；3, connecting rod；4, feed screw nut；5, lead screw；6, pedestal.
Specific embodiment
A kind of specific embodiment of diagnostic couch driving device of the utility model is further described referring to Fig.1.
A kind of diagnostic couch driving device, including pedestal 6 and bed board 1, connect in parallel between the pedestal 6 and the bed board 1
There are two isometric swing arms 2, the both ends of the swing arm 2 are rotatablely connected with the pedestal 6 and the bed board 1 respectively, the pedestal 6
On be fixedly connected with lead screw 5, feed screw nut 4 is arranged on the screw rod, connecting rod 3, the company are hinged on the feed screw nut 4
Bar 3 and the separate one end of the feed screw nut 4 and the swing arm 2 are hinged, and the lead screw 5 is connected with power device, power device
For motor, when motor operation driving lead screw 5 rotates, the rotation of lead screw 5 drives feed screw nut 4 to move axially along lead screw 5, due to silk
Connecting rod 3 is connected between thick stick nut 4 and swing arm 2, feed screw nut 4 is mobile to push connecting rod 3 that swing arm 2 is driven to rotate, to drive bed
The height of plate 1 changes therewith, and two swing arms 2 are isometric and are parallel to each other and are installed between the pedestal 6 and the bed board 1,
So that bed board 1 remains parallel state during lifting, 1 stress equalization of bed board runs smoothly, selects according to demand
5 lead of power of motor and lead screw can control 1 lifting speed of bed board and meet design requirement, because motor and lead screw 5 are all standards
Part, purchase is convenient, can reduce cost of equipment, shortens procurement cycle, this driving device utilizes connecting rod 3, by the flat of feed screw nut 4
Transfer is changed to the rotation of swing arm 2, to realize the lifting of bed board 1, structure is simple, low in cost and can realize the fast of bed board 1
Speed lifting.
The present embodiment is preferred, and the connecting rod 3 and the middle part of the swing arm 2 are hinged, if articulated position is too high, connecting rod 3 is needed
It wants longer, compares waste materials, if articulated position is too low, connecting rod 3 pushes swing arm 2 harder, it is hinged with the middle position of swing arm 2,
Material saving and labour-saving effect are met simultaneously.
Embodiment one: the power device is servo motor.
Embodiment two: the power device is stepper motor.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
