[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 7 As shown, a film reading lamp stand described in an embodiment of the present invention comprises a lamp stand frame 1 and a flexible support plate 11; the flexible support plate 11 is slidably connected to the middle side wall of the lamp stand frame 1 through an extension component; a No. 1 slide groove 13 is symmetrically provided on one side of the lamp stand frame 1 close to the flexible support plate 11; a clamping plate 12 is installed inside the No. 1 slide groove 13, and a plurality of sets of sliding sleeves 5 are sleeved in the middle of the clamping plate 12; the end of the clamping plate 12 is in contact with the side wall of the flexible support plate 11; a support frame 15 is fixedly connected to the middle of the No. 1 slide groove 13 at the rear side of the flexible support plate 11, and an unfolding component is installed in the middle of the support frame 15; the side wall of the support frame 15 is in contact with the side wall of the flexible support plate 11; a positioning column 14 is slidably connected to the middle of the lamp stand frame 1; in the process of medical staff observing the patient's CT film, the lamp stand frame 1 can be adjusted according to the size of the CT film provided by the patient. By pulling on both sides of the line, the flexible support plate 11 and the support frame 15 are respectively changed in position accordingly under the action of the extension component and the unfolding component, so that the length of the lamp frame 1 changes, and the middle part of the structure of the clamping plate 12 slides inside the sliding sleeve 5, so that they can be displaced together. At this time, as the length of the lamp frame 1 increases, medical staff can simultaneously display multiple CT films on the surface of the flexible support plate 11, and fix and separate them by the clamping plate 12. Through the extension effect of the lamp frame 1, it is convenient for medical staff to change the display space of the flexible support plate 11 according to the different sizes of the patient's CT film, thereby increasing the placement area of ​​CT film, and facilitating medical staff and patients to compare multiple different CT films at the same time, speeding up the understanding of the lesion area. At the same time, when not in use, the lamp frame 1 can be reset to reduce space occupancy.

[0024] The above-mentioned unfolding component includes an extension plate 2; the side walls corresponding to the two sides of the above-mentioned support frame 15 are rotatably connected to the extension plates 2; a pair of the tops of the above-mentioned extension plates 2 are rotatably connected to the contact position with a No. 1 rotating shaft 21; a pair of the corresponding side walls of the above-mentioned extension plates 2 are fixedly connected to a No. 1 spring rod 23; the end of the No. 1 spring rod 23 is fixedly connected to a pushing plate 22; a pair of the above-mentioned pushing plates 22 are respectively fixedly connected with magnets that are attracted by magnetic force, and the end of one side of the support frame 15 close to the flexible support plate 11 extends to the side wall of the pushing plate 22; in the process of the lamp holder frame 1 moving to both sides, the extension plate 2 installed in the middle of the support frame 15 can be rotated under the action of the rotating shaft. At this time, the pair of extension plates 2 will move to both sides under the center limit of the No. 1 rotating shaft 21 until the pair of extension plates 2 are in a parallel device. At this time, under the No. 1 spring rod 21, the pair of extension plates 2 will move to both sides. Under the elastic support of the spring rod 23, the No. 1 spring rod 23 will move until it fits with the side wall extending from the end of the support frame 15 to maintain the flatness of the surface of the support frame 15. In the subsequent resetting process, the elastic support effect provided by the No. 1 spring rod 23 can maintain the tightness of the fit between a stack of extension plates 2, and cooperate with the magnetic attraction magnets installed inside the push plate 22 to maintain stability. Through the extension plate 2 installed in the middle of the support frame 15, after the support frame 15 moves to both sides, the rotation effect of the extension plate 2 can keep the middle of the support frame 15 providing support for the flexible support plate 11, so that the surface of the support frame 15 is in a complete state, which is convenient for subsequent medical personnel to clamp and point the CT film, and provide a complete support effect for the CT film, reducing the occurrence of depressions caused by gaps.

[0025] The top of the lamp frame 1 is fixed with handles 3 on both sides of the positioning column 14; the side wall of the lamp frame 1 is provided with a slide rail 31 at the position of the positioning column 14, and the side wall of the positioning column 14 slides inside the slide rail 31; the bottom of the lamp frame 1 is fixed with multiple groups of bases 32; the bottom of the base 32 is rotatably connected with a roller 33; when the medical staff pulls the lamp frame 1 on both sides, the direct sliding effect of the positioning column 14 and the slide rail 31 can increase stability and reduce the jamming caused by deviation. The handle 3 installed on the top of the lamp frame 1 can provide an additional force application position for the medical staff, and can also provide a holding position during the transportation process. At the same time, through the support provided by the multiple groups of bases 32 and the rotation effect of the roller 33, a sliding effect can be provided during the unfolding process of the lamp frame 1. Through the roller 33 installed on the bottom of the base 32, the sliding friction can be changed to rolling friction during the unfolding process of the lamp frame 1, thereby reducing the friction force, thereby increasing the smoothness of the lamp frame 1 during the unfolding process and increasing the unfolding speed.

[0026] A No. 2 slide groove 4 is provided inside the lamp stand frame 1, and the bottom end of the No. 2 slide groove 4 is provided to the middle of the base 32, and the top of the No. 2 slide groove 4 is provided to the bottom of the handle 3; a handle 41 is slidably connected to the top of the No. 2 slide groove 4 through a spring column; a No. 3 slide groove 44 is provided in the middle of the base 32, and the No. 3 slide groove 44 is connected to the No. 2 slide groove 4; a pull rod 43 is slidably connected to the No. 3 slide groove 44 through a spring column, and the top end of the pull rod 43 slides inside the No. 2 slide groove 4; the No. 2 slide groove 4 is provided in a cross shape, and the No. 2 slide groove 4 The two sides are slidably connected with the limit block 45 by spring columns; the end of the limit block 45 is made of rubber material and fits the side wall of the roller 33; the end of the limit block 45 and the bottom of the pull rod 43 are connected by a rope; the bottom of the handle 41 and the top of the pull rod 43 are connected by a connecting rope 42; when the staff unfolds the lamp frame 1, the medical staff can use their fingers to pull the handle 41 upwards while holding the handle 3. At this time, the handle 41 is pulled and connected The rope 42 drives the pull rod 43 to move upward, and then the pull rod 43 pulls the limit block 45 through the rope, so that the end of the limit block 45 loses the contact effect with the side wall of the roller 33, so that the roller 33 rotates smoothly, assisting the staff to complete the unfolding of the lamp frame 1. After the unfolding of the lamp frame 1 is completed, the staff leaves the hand, and the handle 41 is reset under the action of gravity. At the same time, the pull rod 43 and the limit block 45 are reset downward under the elastic force of the spring column, so that the end of the limit block 45 is in contact with the side wall of the roller 33 again. The rubber material limits the rotation of the roller 33 and increases the friction. The staff pulls the handle 41 during the unfolding of the lamp stand frame 1 to maintain the rotation of the roller 33, so that the unfolding process of the lamp stand frame 1 is in a stable sliding state. After the subsequent unfolding is completed, the limit block 45 contacts the roller 33 again to limit the rotation of the roller 33, thereby reducing the mobility of the lamp stand frame 1 after unfolding, increasing stability, and providing a stable observation platform for the patient's CT rubber.

[0027] The No. 1 slide groove 13 is internally slidably connected to a limit ring 52; the middle part of the limit ring 52 is rotatably connected to the No. 2 rotating shaft 51; the side walls of the No. 2 rotating shaft 51 are respectively fixedly connected with a pair of levers 53 at 90 degrees; the side walls of the bottom of the lever 53 are connected to the top of the clamping plate 12; the side walls of the upper and lower ends of the limit ring 52 and the corresponding side walls of the pair of levers 53 are installed with magnetic strips that are attracted by magnetic force; when the staff is placing the patient's CT film, the staff can push the lever 53 upwards to make the clamping plate 12 rotate along the No. 2 rotating shaft 51, so that the side wall of the clamping plate 12 is out of contact with the flexible support plate 11, leaving a gap, at this time, the side wall of the lever 53 will be at the top of the limit ring 52 The side wall is in contact with the clamping plate 12, and the position of the clamping plate 12 is fixed under the magnetic attraction effect of the magnetic strip. At this time, there is a gap between the clamping plate 12 and the flexible support plate 11, and the staff can place the CT film, and then continue to toggle the lever 53 to make it disengage from the top of the limit ring 52, drive the lever 53 to contact the bottom side wall of the limit ring 52, and complete the clamping of the CT film by the clamping plate 12 through the magnetic attraction effect of the magnetic strip. Through simple up and down toggle effects, the clamping and release of the CT film can be completed under the magnetic attraction effect of the magnetic strip, which is convenient for the staff to operate it, and at the same time, multiple CT films can be placed at the same time, which is convenient for the staff and patients to compare the CT films.

[0028] A positioning block 6 is fixedly connected to one side of the clamping plate 12 close to the flexible support plate 11; a plurality of rubber plates 61 are arranged on the side wall of the positioning block 6, and the rubber plates 61 are arranged in an arc shape, and the bending surface protrudes from the side wall of the positioning block 6; a plurality of ventilation holes 62 are arranged in the middle of the rubber plate 61; in the process of the staff installing the patient's CT film, the positioning block 6 installed on the side wall of the clamping plate 12 can contact the CT film through the rubber plate 61 installed on its surface to clamp it. At this time, the rubber plate 61 will be partially deformed under the squeezing force, so that the gas in the ventilation hole 62 is partially discharged, so that the rubber plate 61 and the CT film are more closely attached. The positioning block 6 installed on the side wall of the clamping plate 12 can cooperate with the rubber plate 61 to complete the clamping of the CT film, and the material of the rubber plate 61 itself is used to reduce the damage to the CT film, while increasing the friction, increasing the limiting effect on the CT film, and reducing the occurrence of the CT film falling.

[0029] The side wall of the positioning block 6 is provided with an air storage tank 71 behind the rubber plate 61; the air storage tank 71 is connected with the vent hole 62; the side wall of the air storage tank 71 is provided with a ventilation hole 7; one-way valves 72 are fixedly connected to both ends of the ventilation hole 7; in the process of the rubber plate 61 and the CT film being in contact, the displacement caused by the deformation of the rubber plate 61 will compress the internal space of the air storage tank 71, so that the internal gas is discharged outward along the ventilation hole 7 through the one-way valve 72. At this time, the rubber plate 61 and the surface of the CT film are in contact. Since the one-way valve 72 is one-way, the entry of external gas is limited. At this time, the inside of the air storage tank 71 is in a negative pressure state, so that the position where the vent hole 62 is located and the CT film are adsorbed, and the CT film is further fixed. Through the squeezing force effect between the rubber plate 61 and the CT film, part of the gas in the air storage tank 71 can be discharged outward, so that the rubber plate 61 and the CT film have an adsorption effect, which increases the fixation of the CT film and reduces the occurrence of CT film slippage.

[0030] The bottom of both sides of the base 32 are slidably connected with rubber pads 8 through spring columns; the bottom surface of the rubber pad 8 and the bottom of the roller 33 are at the same level; a fourth slide groove 81 is opened inside the base 32, and the fourth slide groove 81 is respectively connected to the top of the rubber pad 8 and the third slide groove 44; the top of the rubber pad 8 and the pull-out rod 43 are connected by a rope; when the staff pulls the handle 41 to drive the pull-out rod 43 to move, the rubber pad 8 will move upward as the pull-out rod 43 moves, so that the bottom of the rubber pad 8 is separated from the contact with the platform. At this time, the staff can expand the lamp frame 1. After the subsequent expansion of the lamp frame 1 is completed, the rubber pad 8 is reset under the action of the spring column and contacts with the platform surface again. The rubber pads 8 installed on both sides of the bottom of the base 32 can be separated from the contact with the platform surface during the expansion of the lamp frame 1, and can be contacted with the platform surface again after the expansion of the lamp frame 1 is completed, thereby increasing the friction with the platform, increasing the stability of the base 32, and reducing the occurrence of sliding.

[0031] The extension component includes a No. 5 slide slot 9; the end of the No. 5 slide slot 9 is opened on the side wall of the middle part of the lamp stand frame 1, and the interior is located in a circular shape inside the lamp stand frame 1; a torsion spring 91 is fixedly connected to the interior of the No. 5 slide slot 9; the flexible support plate 11 slides inside the No. 5 slide slot 9, and the end is wrapped around the side wall of the torsion spring 91; during the unfolding process of the lamp stand frame 1, the position of the flexible support plate 11 itself remains stable, and under the action of the pulling force, the torsion spring 91 will rotate, so that the flexible support plate 11 wrapped around the torsion spring 91 is continuously displayed outward through the No. 5 slide slot 9. At the same time, under the elastic support provided by a pair of torsion springs 91, the flexible support plate 11 itself is in a tight state, assisting in the placement of CT film. Through the elastic support effect provided by the torsion spring 91, the flexible support plate 11 can always be in a tight support state during the unfolding process of the lamp stand frame 1, maintaining the flatness of the surface of the flexible support plate 11, and cooperating with the support provided by the support frame 15 to complete the display effect of the CT film.

[0032] The No. 3 rotating shaft 101 is rotatably connected to the connecting rope 42 and the rope bending position inside the No. 2 slide groove 4 and the No. 3 slide groove 44, and the No. 3 rotating shaft 101 is in contact with the connecting rope 42 and the rope; in the process of the No. 3 rotating shaft 101 and the rope generating a pulling effect, the existence of the No. 3 rotating shaft 101 can rotate at the connecting rope 42 and the rope bending position, keeping the connecting rope 42 and the rope end parts being pulled in a vertical and parallel state at all times. Through the rotation effect of the No. 3 rotating shaft 101, during the unfolding process of the lamp stand frame 1, the force direction of the pulled parts can be kept in a vertical and parallel state to reduce the jamming caused by the offset, and at the same time reduce the contact between the connecting rope 42 and the rope at the same corner, change the sliding friction to rolling friction, increase the service life, and reduce the risk of breakage.

[0033] During the working process, when the medical staff observes the patient's CT film, they can pull the lamp frame 1 on both sides according to the size of the CT film provided by the patient, so that its flexible support plate 11 and support frame 15 are respectively changed in position under the action of the extension component and the unfolding component, so that the length of the lamp frame 1 changes, and the middle part of the clamping plate 12 slides inside the sliding sleeve 5, so that they can move together. At this time, as the length of the lamp frame 1 increases, the medical staff can simultaneously display multiple CT films on the surface of the flexible support plate 11, fix and partition them through the clamping plate 12, and move the lamp frame 1 to the outside of the lamp frame 1. During the movement on both sides, the extension plate 2 installed in the middle of the support frame 15 can rotate under the action of the rotating shaft. At this time, the pair of extension plates 2 will move to both sides under the central limit of the No. 1 rotating shaft 21 until the pair of extension plates 2 are in a parallel device. At this time, under the elastic support of the No. 1 spring rod 23, the No. 1 spring rod 23 will move until it fits with the side wall extending from the end of the support frame 15 to maintain the flatness of the surface of the support frame 15. In the subsequent resetting process, the elastic support effect provided by the No. 1 spring rod 23 can maintain the tight fit between the pair of extension plates 2, and cooperate with the magnetic attraction installed inside the push plate 22 to keep Stability. When medical staff pulls the lamp frame 1 on both sides, the direct sliding effect of the positioning column 14 and the slide rail 31 can increase stability and reduce the jamming caused by deviation. The handle 3 installed on the top of the lamp frame 1 can provide an additional force application position for medical staff, and can also provide a holding position during transportation. At the same time, through the support provided by multiple groups of bases 32 and the rotation effect of the roller 33, a sliding effect can be provided during the unfolding process of the lamp frame 1. When the staff unfolds the lamp frame 1, the medical staff can use their fingers to pull the handle 41 upward while holding the handle 3. At this time, the handle 41 is pulled, and the pull rod 43 is driven to move upward through the connecting rope 42, so that the pull rod 43 pulls the limit block 45 through the rope, so that the end of the limit block 45 loses the contact effect with the side wall of the roller 33, so that the roller 33 rotates smoothly, assisting the staff to complete the unfolding of the lamp frame 1. After the unfolding of the lamp frame 1 is completed, the staff's hands leave, and the handle 41 is reset under the action of gravity. At the same time, the pull rod 43 and the limit block 45 are reset downward under the elastic force of the spring column, so that the end of the limit block 45 contacts the side wall of the roller 33 again, and the rotation of the roller 33 is limited under the action of the rubber material, thereby increasing the friction force; When the staff is placing the patient's CT film, the staff can push the lever 53 upward to make the clamping plate 12 rotate along the second rotation axis 51, so that the side wall of the clamping plate 12 is out of contact with the flexible support plate 11, leaving a gap. At this time, the side wall of the lever 53 will contact the top side wall of the limiting ring 52, and the position of the clamping plate 12 will be fixed under the magnetic attraction effect of the magnetic strip. At this time, there is a gap between the clamping plate 12 and the flexible support plate 11, and the staff can place the CT film, and then continue to push the lever 53 to make it out of contact with the top of the limiting ring 52, drive the lever 53 to contact the bottom side wall of the limiting ring 52, and complete the clamping of the CT film by the clamping plate 12 through the magnetic attraction effect of the magnetic strip. When the staff is installing the patient's CT film, the clamping The positioning block 6 installed on the side wall of the plate 12 can contact the CT film through the rubber plate 61 installed on its surface to clamp it. At this time, the rubber plate 61 will be partially deformed under the extrusion force, so that the gas in the vent 62 is partially discharged, so that the rubber plate 61 and the CT film are more closely fitted. In the process of the rubber plate 61 and the CT film contacting, the displacement caused by the deformation of the rubber plate 61 will compress the internal space of the gas storage tank 71, so that the internal gas is discharged outward along the ventilation hole 7 through the one-way valve 72. At this time, the rubber plate 61 and the surface of the CT film are in contact. Since the one-way valve 72 is one-way, the entry of external gas is limited. At this time, the inside of the gas storage tank 71 is in a negative pressure state, so that the position of the vent 62 and the CT film are adsorbed, and the CT film is further fixed; When the staff pulls the handle 41 to drive the pull rod 43 to move, the rubber pad 8 will be displaced as the pull rod 43 moves upward, so that the bottom of the rubber pad 8 is out of contact with the platform. At this time, the staff can unfold the lamp frame 1. After the subsequent unfolding of the lamp frame 1 is completed, the rubber pad 8 is reset under the action of the spring column and contacts the platform surface again. During the unfolding of the lamp frame 1, the position of the flexible support plate 11 itself remains stable. Under the action of the pulling force, the torsion spring 91 will rotate, so that the flexible support plate 11 wrapped around the torsion spring 91 is continuously displayed outward through the No. 5 slide groove 9. At the same time, under the elastic support provided by a pair of torsion springs 91, the flexible support plate 11 itself is in a taut state, which assists in the placement of the CT film. During the pulling effect of the No. 3 rotating shaft 101 and the rope, the existence of the No. 3 rotating shaft 101 can rotate at the bending position of the connecting rope 42 and the rope, so as to keep the pulling effect on the connecting rope 42 and the rope end parts always in a vertical and parallel state.
