Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a protective device for imaging departments. Background Technology

[0002] Radiological protection devices are a series of equipment and instruments used to protect patients, medical staff, and the surrounding environment from radiation during medical imaging examinations. These include lead rooms and lead screens. Lead screens generally refer to movable lead plate screens, with the core material being pure lead plates with a purity of 99.994% or higher. Lead has a high density and can effectively absorb and block high-energy radiation such as X-rays and gamma rays. In some bedside X-ray examinations or scenarios where additional protection is temporarily required, they can be flexibly placed near patients or staff to block direct radiation exposure and are suitable for local protection.

[0003] Currently, lead screens may cause space congestion during use. Since the space in the examination room of the radiology department is usually limited, especially in some small departments, the lead screen itself has a certain volume and thickness. Placing it in the examination room may make the already tight space even more crowded, causing inconvenience to the operation of medical staff and the movement of equipment, and may also affect the comfort and convenience of patients during the examination process. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: A radiology protective device, comprising: The frame has first lead plates embedded on both its front and rear sides. A pair of first support frames are connected to both the front and rear sides of the first lead plates. A second base is fixedly connected to the bottom of the first support frame. A pair of second casters are connected to the bottom of the second base. A lifting plate is slidably connected to the bottom of the second base at the middle position of the pair of second casters. A pair of support columns are connected to the bottom of the lifting plate. Rubber pads are connected to the bottom of the support columns. A lifting mechanism is provided on the top of the lifting plate. The frame has a pair of guide slots on its upper and lower sides. The second lead plate and the third lead plate are slidably connected to the left and right sides of the frame. The upper and lower positions of the adjacent sides of the second lead plate and the third lead plate are respectively connected to the first L-shaped rod and the second L-shaped rod. The outer sides of the first L-shaped rod and the second L-shaped rod are provided with guide mechanisms. The top of the first L-shaped rod is provided with a drive mechanism through the guide slot. The end of the second L-shaped rod is provided with a second knob through the guide slot. The second knob is provided with a first through hole. The bottom of the second knob is provided with a rotation mechanism. The second lead plate and the third lead plate are threaded to the front and rear sides with second support frames. The bottom of the second support frame is fixedly connected to a first base, and the bottom of the first base is respectively connected to a pair of first universal wheels.

[0005] In one possible implementation, the drive mechanism includes a servo motor, one end of the output shaft of the servo motor is connected to a bidirectional lead screw, a pair of first ball nut pairs are sleeved on the outer side of the bidirectional lead screw, a sleeve is connected to the bottom of the first ball nut pairs, the sleeve is sleeved on the top end of the first L-shaped rod and rotatably connected to the first L-shaped rod, and one end of the bidirectional lead screw is rotatably connected to a first bearing seat.

[0006] In one possible implementation, the top of the frame is connected to a housing above a pair of guide slots, one side of the servo motor is fixedly connected to the housing, and one side of the first bearing seat is fixedly connected to the housing.

[0007] In one possible implementation, the rotating mechanism includes a U-shaped plate, both sides of which are fixedly connected to a second knob. A second through hole is provided at the bottom of the U-shaped plate, and a rod is inserted through the interior of the second through hole. A lever is connected to the end of the rod, and the top of the rod penetrates the interior of a first through hole. A circular plate is fixedly connected to the outside of the rod, and a return spring is sleeved on the outside of the rod. One end of the return spring is fixedly connected to the circular plate, and the other end of the return spring is fixedly connected to the U-shaped plate.

[0008] In one possible implementation, the bottom of the frame is provided with a plurality of third through holes circumferentially near the ends of a pair of guide slots, and the top end of the insert extends into the interior of the third through holes.

[0009] In one possible implementation, the guiding mechanism includes a pair of slide rails, the back of which is fixedly connected to the side wall of the frame. A first slider is slidably connected inside the slide rails, a side plate is connected to the outside of the first slider, and a bearing is connected to one side of the side plate. The bearing is rotatably connected to a second L-shaped rod.

[0010] In one possible implementation, the lifting mechanism includes a pair of second bearing seats, the bottom of which is fixedly connected to a second base. A reciprocating screw is rotatably connected inside the pair of second bearing seats. The left end of the reciprocating screw passes through the interior of the second base and is connected to a first knob. A second ball nut assembly is sleeved on the outside of the reciprocating screw. A fixing sleeve is fixedly connected to the outside of the second ball nut assembly.

[0013] In one possible implementation, a pair of guide sleeves are connected to both side walls of the second base, and a guide rod is slidably connected inside the guide sleeve, with the end of the guide rod being fixedly connected to the lifting plate.

[0014] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By activating the servo motor at the top of the frame, the bidirectional lead screw can be rotated, which in turn drives the first ball bearing nut pair on both sides and the sleeve at the bottom to move towards each other. This, in turn, drives the second and third lead plates on both sides to move towards each other, thus facilitating the adjustment of the distance between the second and third lead plates on both sides. This, in turn, facilitates the adjustment of the overall telescopic length of the lead screen, reducing the footprint of the lead screen to save space and avoid potential space congestion.

[0015] 2. By pulling down the lever, the top of the insertion rod can be easily removed from the third through hole at the bottom of the frame. Then, the second knob can be rotated to rotate the second L-shaped rod, which in turn makes it easy to adjust the angle of the second lead plate. This allows the lead plates on both sides to be flexibly adjusted according to the actual use scenario and protection requirements, and can effectively utilize space in spaces of different sizes.

[0016] 3. By rotating the first knob, the reciprocating screw is rotated, which facilitates the sliding of the second ball nut pair and the fixing sleeve to the right, thereby causing the slide plate to slide to the right and contact the second slider. As the slide plate continues to slide to the right, it facilitates the descent of the second slider and the bottom lifting plate, lowering the support column and rubber pad to contact the ground, making it easy for the second caster to move away from the ground. After moving to the designated position, it can be easily locked to ensure that the lead screen will not move arbitrarily during use, thus ensuring the accuracy and stability of the protection.

[0021] This application provides a radiological protective device to solve the problems in the prior art.

[0022] The technical solution in this application is to solve the above problems, and the overall approach is as follows: like Figures 1-9 As shown, a radiology protective device includes: The frame 3 has a first lead plate 2 embedded on both the front and rear sides. A pair of first support frames 6 are connected to both the front and rear sides of the first lead plate 2. A second base 13 is fixedly connected to the bottom of the first support frame 6. A pair of second casters 12 are connected to the bottom of the second base 13. A lifting plate 15 is slidably connected to the bottom of the second base 13 at the middle position of the pair of second casters 12. A pair of support columns 14 are connected to the bottom of the lifting plate 15. A rubber pad 10 is connected to the bottom of the support columns 14. A lifting mechanism is provided on the top of the lifting plate 15. A pair of guide slots 17 are provided on both the upper and lower sides of the frame 3. The second lead plate 4 and the third lead plate 5 are slidably connected to the left and right sides of the interior of the frame 3, respectively. The upper and lower positions of the adjacent sides of the second lead plate 4 and the third lead plate 5 are respectively connected to the first L-shaped rod 23 and the second L-shaped rod 24. The outer sides of the first L-shaped rod 23 and the second L-shaped rod 24 are provided with guide mechanisms. The top of the first L-shaped rod 23 passes through the interior of the guide slot 17 and is provided with a drive mechanism. The end of the second L-shaped rod 24 passes through the interior of the guide slot 17 and is connected to the second knob 16. The interior of the second knob 16 is provided with a first through hole 29. The bottom of the second knob 16 is provided with a rotation mechanism. The second lead plate 4 and the third lead plate 5 are threaded to the front and rear sides with a second support frame 7. The bottom of the second support frame 7 is fixedly connected to a first base 8. The bottom of the first base 8 is connected to a pair of first casters 9.

[0023] In some examples, the drive mechanism includes a servo motor 21, one end of the output shaft of the servo motor 21 is connected to a bidirectional lead screw 20, a pair of first ball nut pairs 19 are sleeved on the outside of the bidirectional lead screw 20, a sleeve 22 is connected to the bottom of the first ball nut pairs 19, the sleeve 22 is sleeved on the top end of the first L-shaped rod 23 and is rotatably connected to the first L-shaped rod 23, and one end of the bidirectional lead screw 20 is rotatably connected to a first bearing seat 18.

[0024] In some examples, the top of the frame 3 is connected to the housing 1 above a pair of guide slots 17, one side of the servo motor 21 is fixedly connected to the housing 1, and one side of the first bearing seat 18 is fixedly connected to the housing 1.

[0025] In some examples, the rotating mechanism includes a U-shaped plate 32, both sides of which are fixedly connected to the second knob 16. A second through hole 31 is provided at the bottom of the U-shaped plate 32, and a rod 30 is connected through the inside of the second through hole 31. A lever 36 is connected to the end of the rod 30, and the top of the rod 30 passes through the inside of the first through hole 29. A circular plate 34 is fixedly connected to the outside of the rod 30, and a return spring 35 is sleeved on the outside of the rod 30. One end of the return spring 35 is fixedly connected to the circular plate 34, and the other end of the return spring 35 is fixedly connected to the U-shaped plate 32. By pulling down the lever 36, the top of the rod 30 can be easily removed from the third through hole 33 at the bottom of the frame 3, and then the second knob 16 can be rotated to rotate the second L-shaped rod 24, thereby facilitating the adjustment of the angle of the second lead plate 4.

[0026] In some examples, the bottom of the frame 3 is provided with several third through holes 33 circumferentially near the ends of a pair of guide slots 17. The top end of the insert rod 30 extends into the interior of the third through hole 33. When the top end of the insert rod 30 is inserted into the interior of the third through hole 33, the second knob 16 is limited. Otherwise, the second knob 16 can be rotated.

[0027] In some examples, the guiding mechanism includes a pair of slide rails 27, the back of which is fixedly connected to the side wall of the frame 3. A first slider 26 is slidably connected inside the slide rails 27. A side plate 25 is connected to the outside of the first slider 26. A bearing 28 is connected to one side of the side plate 25. The bearing 28 is rotatably connected to the second L-shaped rod 24. The connection between the slide rails 27 and the first slider 26 facilitates the flexible sliding of the lead plates on both sides along the left and right sides. The bearing 28 facilitates the flexible rotation of the L-shaped rods on the upper and lower sides.

[0028] In some examples, the lifting mechanism includes a pair of second bearing seats 37, the bottom of which is fixedly connected to a second base 13. A reciprocating screw 38 is rotatably connected inside the pair of second bearing seats 37. The left end of the reciprocating screw 38 passes through the interior of the second base 13 and is connected to a first knob 11. A second ball nut assembly 40 is sleeved on the outside of the reciprocating screw 38. A fixing sleeve 39 is fixedly connected to the outside of the second ball nut assembly 40. A sliding plate 44 is connected to the bottom of the fixing sleeve 39. A pair of second sliders 41 are slidably connected to the right side of the sliding plate 44. The bottom of the second sliders 41 is connected to the lifting plate 1. 5. Fixed connection: Rotating the first knob 11 drives the reciprocating screw 38 to rotate, which facilitates the sliding of the second ball nut pair 40 and the fixing sleeve 39 to the right, thereby driving the slide plate 44 to slide to the right and contact the second slider 41. As the slide plate 44 continues to slide to the right, it facilitates the driving of the second slider 41 and the bottom lifting plate 15 to descend, lowering the support column 14 and the rubber pad 10 to contact the ground, making it easy to move the second universal wheel 12 away from the ground. After moving to the designated position, it can be easily locked to ensure that the lead screen will not move at will during use, ensuring the accuracy and stability of the protection.

[0029] In some examples, the right side of the slide plate 44 and the left side of the second slider 41 are both rounded, which facilitates the sliding of the slide plate 44 along the outer surface of the second slider 41.

[0030] In some examples, the second slider 41 is set in a right-angled trapezoidal shape, which slides to the right by the slide plate 44 and comes into contact with the second slider 41. As the slide plate 44 continues to slide to the right, it facilitates the descent of the second slider 41 and the lifting plate 15 at the bottom.

[0031] In some examples, a pair of guide sleeves 43 are connected to both sides of the second base 13. A guide rod 42 is slidably connected inside the guide sleeve 43. The end of the guide rod 42 is fixedly connected to the lifting plate 15. The sliding connection between the guide sleeve 43 and the guide rod 42 helps to ensure that the lifting plate 15 can be lifted vertically.

[0032] This invention utilizes a servo motor 21 at the top of the frame 3 to rotate a bidirectional lead screw 20, which in turn moves the first ball bearing nut pair 19 on both sides and the sleeve 22 at the bottom toward each other. This, in turn, moves the second lead plate 4 and the third lead plate 5 on both sides toward each other, allowing for easy adjustment of the distance between the second lead plate 4 and the third lead plate 5. This, in turn, allows for easy adjustment of the overall telescopic length of the lead screen, reducing its footprint and saving space. Furthermore, by pulling down the lever 36, the top of the insert 30 can be easily removed from the third through hole 33 at the bottom of the frame 3. Then, the second knob 16 can be rotated to rotate the second L-shaped rod 24, allowing for easy adjustment of the angle of the second lead plate 4. This enables the lead plates on both sides to be flexibly adjusted according to actual usage scenarios and protection requirements, effectively utilizing space in spaces of different sizes.

[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
