Abstract
The utility model relates to a rotating scale indication device for a radiotherapy simulator, belonging to auxiliary devices of medical equipment. The device comprises a dial, a pointer, an outer over and a rotating shaft, wherein a scale window is arranged on the outer cover. The device is characterized in that the dial is fixed on a rack through a fixing plate; the device is provided with the rotating shaft; the pointer is fixed on the outer cover which is fixed on a shaft sleeve; the shaft sleeve is sleeved on the rotating shaft; and a bearing is assembled between the rotating shaft and the shaft sleeve. Through adjusting the relative structure of the pointer and the dial, the phenomenon that the dial rotates along with the rack but the pointer keeps stationary is realized. The device with simple structure, convenient operation and reliable performance can ensure the pointer keeps vertical when the rack rotates, and ensure that an operator can read the angle of the rack by standing naturally, so that not only reading is facilitated, but also the error of reading is reduced and the accuracy of reading is ensured.
Description
Technical field
This utility model relates to a kind of radiotherapy simulator rotation scale indicating device, belongs to the armarium auxiliary device.
Background technology
Radiotherapy simulator rotation scale indicating device is used to indicate the frame anglec of rotation.In the existing radiotherapy simulator rotation scale indicating device, pointer and frame are fixed, and pointer rotates with frame, and inconvenience during reading especially can cause error in reading during the inconvenient reading in pointer position, causes reading to be forbidden.
The utility model content
The purpose of this utility model is to provide a kind of radiotherapy simulator rotation scale indicating device, and error in reading is little again to make things convenient for reading.
Radiotherapy simulator rotation scale indicating device described in the utility model, graduated disc, pointer, outer housing and rotating shaft are arranged, outer housing is provided with the scale form, it is characterized in that graduated disc is fixed on the frame and is provided with rotating shaft, pointer is fixed on the outer housing, outer housing is fixed on axle sleeve, and axle sleeve is sleeved in the rotating shaft.
By adjusting the relative structure of pointer and graduated disc, graduated disc is along with rotation when frame is rotated, and pointer is motionless, and error in reading is little again to make things convenient for reading.
Graduated disc can be fixed on the frame by fixing head, and rotating shaft is fixed on the fixing head.
Equipped bearing between rotating shaft and axle sleeve to reduce rotating shaft and shaft room frictional force in relative rotation, guarantees that the outer housing eccentric moment overcomes the frictional resistance of rotating shaft, makes pointer be in the operating position all the time.
Heavy in the establishing of outer housing bottom, by action of gravity, can guarantee that pointer is in vertical position all the time.
This utility model radiotherapy simulator rotation scale indicating device, by adjusting the relative structure of pointer and graduated disc, graduated disc is along with rotation when realizing the frame rotation, and pointer is motionless, and is simple in structure, easy to operate, dependable performance, pointer is in vertical state all the time in the time of can guaranteeing the frame rotation, and operator's nature standing state gets final product when reading frame angle, not only make things convenient for reading but also reduced error in reading, guaranteed the accuracy of reading.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
A-A cross section structure sketch map among Fig. 2, Fig. 1.
Among the figure: 1, graduated disc 2, pointer 3, gland 4, outer housing 5, fixing head 6, pad post 7, rotating shaft 8, axle sleeve 9, bearing 10, counterweight.
The specific embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, radiotherapy simulator rotation scale indicating device described in the utility model, graduated disc 1, pointer 2, outer housing 4 and rotating shaft 7 are arranged, and graduated disc 1 is fixed on the frame by fixing head 5, and rotating shaft 7 is fixed on the fixing head 5, pointer 2 is fixed on the outer housing 4, outer housing 4 is provided with the scale form, and outer housing 4 is fixed on the axle sleeve 8 by gland 3, and axle sleeve 8 is sleeved in the rotating shaft 7, be fitted with bearing 9 between rotating shaft 7 and the axle sleeve 8, the bottom of outer housing 4 is provided with counterweight 10.
When frame was rotated, fixing head 5 drove graduated disc 1, rotating shaft 7 rotations.At this moment, because the frictional force of bearing 9 is very little, can not overcome the eccentric moment of outer housing 4, so outer housing 4 is motionless, pointer 2 is in vertical position all the time, and the number of degrees of pointer 2 indication graduated discs 1 are the shelf position angle, convenient reading, and error in reading is again little.
