This is configured to include a lifting device 300 and a mounting arm 400 that is mounted on the lifting device to mount the X-ray imaging equipment, and includes a horizontal support frame 100 , a vertical frame 200 , and a lifting device. (300), the mounting arm 400 is characterized in that it is possible to stably mount the X-ray imaging equipment (A) while simply assembling the individual parts without welding work and to easily adjust the height of the equipment.

First, the frame assembly structures of the cradle of the present invention can be manufactured using a metal tube made of a pipe shape. In particular, the horizontal support frame 100 , which occupies a relatively large volume, is made to be lightweight while making disassembly and assembly easy. In order to do this, assembly may be made with a metal square tube.

In addition, the front end of the mounting arm 400 is formed in a state in which the X-ray imaging equipment is suspended and mounted at a predetermined height on the upper end of the cradle.

To this end, a horizontal support frame 100 supported in a horizontal state is provided on the ground, and the horizontal support frame 100 has a support bar 120 formed across the left and right sides, and is supported on both sides of the support bar 120 . The bar 140 is configured in a shape close to the 'H' shape so that it can be stably supported on the ground.

At this time, since the X-ray imaging equipment is mounted on the front end of the mounting arm 400, the center of gravity is biased forward. In order to stably maintain the center of gravity while the vertical frame 200 is upright, the support bar 120 is supported. It is assembled biasedly at the rear of the bar 140 to prevent the X-ray imaging equipment from twisting forward and to be able to support it stably, and at this time, the support bar 140 is made in a shape with an open front to increase the radius supported on the ground more It can be enlarged to be supported more stably, and the flaring angle can be made in the range of 15 to 45°.

And as a structure for the support bar 120 and the support bar 140 to be assembled in a prefabricated manner, the support bar 120 and the support bar 140 are composed of a square tube, as shown in FIG. By attaching and assembling the link member 130, the horizontal support frame 100 can be assembled with a simple assembly structure, and both ends of each tube can be closed by inserting a closing cap such as an elastic material or synthetic resin.

At this time, the link member 130 is manufactured in a 'T' shape, but in order to be assembled in a state where the support bar 140 is opened, the fastening parts assembled at the front and the rear around the support bar 120 are The front end of the support bar 140 assembled to both ends of the support bar 120 as described above by positioning the 'T'-shaped link members 130 at regular intervals to be eccentric by a predetermined angle on one side rather than an orthogonal structure. The opening angle is to form an open shape in the range of 15 to 45°.

And the support bar 120 and the link member 130, the support bar 140 and the link member 130 can be assembled using a fastener 104 that is assembled in a bolt and nut method in a male and female structure, respectively. , for this purpose, the support bar 120 , the link member 130 , and the support bar 140 may have a through hole 102 formed at a connecting portion connected to each other to penetrate through the fastener 104 .

Alternatively, the link member 130 can be integrally configured with the support bar 120 or the support bar 140, and when the link member 130 is integrally formed with the support bar 120, the support bar ( The assembly process of 120) and the link member 130 is omitted, and the support bar 140 is placed on the upper end of the link member 130 in a state where the support bar 120 is placed horizontally so that there is no deviation in height. ) and the support bar 140 can be easily assembled in the correct position.

In addition, moving wheels are mounted on the front and rear ends of the support bar 140, respectively, so that shooting is possible while moving the place in a state in which the cradle is assembled.

In addition, a guide frame 122 having a structure in which a hollow tube body protrudes upward so that the vertical frame 200 can be inserted into the upper portion of the support bar 120 may be further configured.

The inner diameter of the guide frame 122 may be configured to correspond to the outer diameter of the vertical frame 200 so that the vertical frame 200 can be inserted into the guide frame 122 to stand upright, at this time the guide frame 122 ) is equipped with a tightening bolt 124 to firmly assemble the vertical frame 200 .

As shown in FIG. 4 , the vertical frame 200 is divided into an upper body 220 and a lower body 240 and can be configured in a prefabricated manner, and the upper and lower parts are bolted by bar nut 230 . Assembled to have a structure, each assembly part is disassembled to enable storage and movement.

In the assembly using the bar nut 230, the upper and lower bodies 220 and 240 are formed with inner portions 222 and 242, and the bar nut 230 is inserted into the inner portion, and then the fastener 204 is inserted into the through hole 202. By assembling, the upper and lower body may be configured to be integrally assembled with one vertical frame 200 .

And in this inner part, a screen may be formed in order to prevent the connection part of the vertical frame 200 from being exposed to the outside, and the screen structure is a plate-shaped structure made of a translucent or opaque material inserted into the inner part in a slide manner to prevent the connection part from being exposed to the outside. This can be done so that it is not exposed to the outside.

At this time, when the vertical frame 200 is formed too long, packaging is difficult, storage and portability are difficult. When the vertical frame 200 is separated into upper and lower parts, the length of each of the upper body and the lower body is measured as a horizontal support frame. By forming the support bar 140 to correspond to the length of the support bar 140 in the separated state, the packaging volume can be minimized.

That is, the vertical frame 200 is preferably formed within 2000mm for the convenience of use, and is formed to have a length of 800±100mm in a state where the upper and lower parts are divided into equal parts, and the length of the divided upper and lower body is Correspondingly, by forming the length of the support bar 120 and the support bar 140 of the horizontal support frame 100 to correspond to the length of the upper and lower body or to be relatively shorter than that, the packaging volume can be minimized, and most preferably For stable support of the horizontal support frame 100, the length of the support bar 140 is preferably formed to be 800±100 mm.

Therefore, as described above, since the horizontal support frame 100 and the vertical frame 300, as well as the lifting device 300 and the mounting arm 400, can all be easily separated, the packaging volume as shown in FIG. can be configured very compactly, and while reducing logistics costs in the distribution process, it is easy to carry and move, and it is easy to reassemble after disassembly, so it can greatly improve mobility in response to various on-site situations in various places. .

In addition, a lifting device 300 is mounted on the vertical frame 200 so as to adjust the upper and lower heights, and the lifting device 300 is mounted on the housing 320 as shown in FIGS. 5 and 8 . The through part 322 is formed and has a structure that can flow up and down in a state in which it is inserted penetratingly into the vertical frame 200 , and the lever 360 in a state in which the driving part 340 is engaged with the vertical frame 200 with a gear and fixed. ), the gear is engaged and the lifting device 300 can be lifted up and down, and the X-ray imaging equipment is mounted on the mounting arm 400 to be close to the object to be photographed. be able to do

At this time, the vertical frame 200 has a rack gear 260 formed along the longitudinal direction of the vertical frame, and the lifting device 300 has a driving gear 342 so that the driving unit 340 is engaged with the rack gear 260 . It may be configured to rotate by being shaft-coupled to the drive shaft 344 .

The leg gear 260 is mounted on the inner inlets 222 and 242 of the upper and lower bodies 220 and 240 formed in the vertical frame 200 and is configured to be exposed to the outside, and the leg gear is exposed to the outside of the vertical frame 200 . In this state, the drive gear 342 is exposed through the through part 322 formed in the housing 320 of the lifting device 300, so that simply inserting and fitting the lifting device 300 into the vertical frame 200 is a leg gear ( 260 and the driving gear 342 may be engaged to enable the gear operation.

To this end, the rack gear 260 may be formed to extend from the uppermost end of the vertical frame 200 to the lower end in the longitudinal direction, and the assembly of the recg gear 260 passes through the rear where the rack gear 260 is mounted. By forming the through-hole 202 to do so and assembling it with the fastener 204, it can be easily fixed.

And the lever 360 is provided to be interlocked with the rotating plate 362 coaxially rotated with the driving shaft 344, the rotating plate 362 is formed with a rotation control element 364 so that rotation control in one or both directions is made. can do.

That is, as shown in FIG. 9, the rotation control element 364 is a shaft pin 364a in the cutout 362a of the rotation plate 362 in a state in which the rotation plate 362 is mounted in close contact with the inner diameter of the cylinder 363. This is inserted, and the shaft pin 364a is mounted to have a repulsive force by the compression spring 364b to control the rotation of the rotating plate 362, prevent the lever 360 from being arbitrarily rotated, and adjust the height of the X-ray imaging equipment. to keep the status quo constant.

At this time, the rotation control element 364 is preferably mounted so that the shaft pin 364a has a repulsive force by the compression spring 364b in both directions in which the rotation plate 362 rotates, so that bidirectional control is achieved, and the lever 360 ), the shaft pin 364a moves in one direction according to the rotation direction, and the up and down lifting operation is made through the rotation of the driving gear 342 .

If the operating structure of the rotation control element 364 is described in more detail, the shaft pins 364a on both sides support the rotation plate 362 from both sides so that the rotation plate 362 is not arbitrarily rotated by the restoring force of the compression spring 364b, and the height setting is made. Block the gear operation in

Therefore, even if the X-ray imaging equipment is operated, it is possible to stably perform imaging without any upward or downward movement.

And when the user applies an external force to turn the lever 360 clockwise, the rotating plate 362 rotates clockwise as shown in FIG. 10, and the left shaft pin 364a is pushed up finely and the rotating plate is operated while allowing the driving gear 342 to rotate clockwise, the driving gear 342 is engaged with the rack gear 260 mounted on the rear of the vertical frame 200 and rotates while the lifting device 300 descends. .

Conversely, when the user applies an external force and turns the lever 360 counterclockwise, the rotating plate 362 rotates counterclockwise, and the shaft pin 364a on the right is slightly pushed up to allow the operation of the rotating plate. As the driving gear 342 rotates counterclockwise, the driving gear 342 is engaged with the rack gear 260 mounted on the rear of the vertical frame 200 and rotates while the lifting device 300 rises.

Therefore, even if heavy X-ray imaging equipment is hung on the mounting arm 400, the height of the imaging equipment does not move arbitrarily unless an external force acts on it, and the jamming state occurs only when the user manipulates the lever 360 forcibly. It is released to enable up/down lifting operation.
