Abstract
The utility model relates to a spot film frame transmission mechanism for X-ray gastrointestinal diagnosis machine, which belongs to auxiliary device field of radio diagnosis treatment equipment, and is characterized in that the transmission mechanism is gear-rack motion pair transmission mechanism; the gear is mounted on the drive shaft of a linear motor and is meshed with a transmission rack; the transmission rack is fixedly connected with a spot film frame. The spot film frame transmission mechanism for X-ray gastrointestinal diagnosis machine has simple structure, avoids belt loose and aging phenomenon, avoids frequency adjustment and maintenance, is convenient in mounting and use, and has low cost and ensures the positioning of spot film to be more accurate.
Description
Technical field
This utility model relates to a kind of radiodiagnosis stomach and intestine machine spot film frame transmission mechanism, belongs to the auxiliary device of radiodiagnosis therapeutic equipment.
Background technology
The vertical and horizontal motion of radiodiagnosis stomach and intestine machine point horse commonly used, the motor that is that adopts carries out transmission by reduction box driving synchronous belt, need consider belt adjustment mechanism during design, adjusts the length of belt during installation, structure is complicated, and behind the some horse placement film magazine constant weight is arranged, and long-time the use, the length of band meeting synchronously is elongated, need constantly adjust, phenomenons such as aging also take place in belt easily under the irradiation of X ray, directly have influence on the localized accuracy of a horse.
The utility model content
The purpose of this utility model is to provide a kind of improved radiodiagnosis stomach and intestine machine spot film frame transmission mechanism, and is simple in structure, installation, easy to use, and cost is low, and some horse location is more accurate.
Radiodiagnosis stomach and intestine machine spot film frame transmission mechanism described in the utility model is rack-and-pinion kinematic pair drive mechanism, and gear is installed on the driving shaft of linear motor, and is meshed with driving rack, and driving rack is fixedlyed connected with the some horse.
Dc motor driven wheel, gear drive tooth bar again, and rack drives point horse moves.Corresponding to laterally moving and vertically moving, can be equipped with two these drive mechanisms of cover respectively, realize respectively laterally moving and vertically moving.
This utility model radiodiagnosis stomach and intestine machine spot film frame transmission mechanism compared with prior art has following beneficial effect:
Adopt rack-and-pinion kinematic pair drive mechanism, simple in structure, avoided lax, the catabiosis of belt, need not to adjust often, safeguard, to install, easy to use, cost is low, and makes that some horse location is more accurate.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, dc motor 2, driving rack 3, gear.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, radiodiagnosis stomach and intestine machine spot film frame transmission mechanism described in the utility model is rack-and-pinion kinematic pair drive mechanism, and gear 3 is installed on the driving shaft of linear motor 1, and be meshed with driving rack 2, driving rack 2 is fixedlyed connected with the some horse.Dc motor 1 driven wheel 3 rotates, and gear 3 drives tooth bar 2 again and moves, and driving rack 2 can drive a horse and move.
