Description
Technical field
The utility model relates to a kind of DR image beds to heart regulating device.
Background technique
DR refers to a kind of new technology for directly carrying out Digital X-ray Radiotive under the control of the computer, that is, uses amorphous silicon flat panel
The X-ray information for penetrating human body is converted into digital signal by detector, and by computer reconstruction image and carries out a series of figure
As the system of post-processing.DR product mainly has three kinds of double columns, sickle arm and suspention currently on the market.Wherein the bis- columns of DR produce
Product, due to the difference of patient's irradiation position, it is desirable that DR bed board can portraitlandscape move freely, so that operator examines every time
When surveying patient's different parts, needs to be aligned the cross centre line of bed board and plate, be zeroed again.
And at present there are mainly two types of the solutions that are zeroed again on the market: one is the synchronizing device of plate and bulb with
Laser sensor is used cooperatively, and plate cross centre line vertical line is known by the interlinked mechanism of plate and bulb, using on bulb
Lamp is got on bed board, and the vertical line of bed board and plate cross hairs is aligned, and whether recycles laser sensor induction bed board cross horizontal line
Alignment, after alignment, buzzer warning, this structure is not only expensive, and structure is not compact, increases the difficulty of design, circuit control
The difficulty of system, and return-to-zero-time is longer, and product service efficiency is lower；Another kind uses drawstring encoder and laser sensor knot
It closes, using drawstring encoder alignment bed board and plate cross centre line vertical line, utilizes laser sensor alignment bed board and plate ten
Word center line horizontal line, thus the step of reaching zero, zero process needs operator constantly to see display screen numerical value, so that behaviour
It makes comparisons time-consuming, same this method is expensive, whole system bad stability.
In summary, DR image bed in the prior art has following defects that heart regulating device
1): using synchronizing device combination laser sensor and the dress of drawstring encoder combination laser sensor design scheme
It is excessively complicated to install meter, increases the complexity of whole equipment.
2): existing scheme installation operation is relative complex.
3): it is not good enough that existing scheme product increases electronic product stability, leads to maintenance cost height.
4): existing design higher cost.
It because urgently a kind of structure is simple in the industry, operates conveniently, the low DR image bed of manufacturing cost is to heart regulating device.
Summary of the invention
The utility model aim is: a kind of structure letter is provided for the defect in the prior art mentioned in background technique
It is single, it operates conveniently, the low DR image bed of manufacturing cost is to heart regulating device, between the bed board and plate that can be realized DR image bed
It is efficient to the heart reset operate, reduce medical and nursing work amount, improve DR system operating efficiency.
The technical solution of the utility model is: a kind of DR image bed is to heart regulating device, including bedstead and sliding by straight line
Rail regulating mechanism is installed on the bed board on bedstead, and is mounted on the DR plate on bedstead and being located at below bed board, and feature exists
