[0028] To make the objectives, technical solutions and advantages of the present utility model clearer, the following describes the utility model clearly and completely with reference to specific embodiments.

[0029] Embodiment 1:

[0030] As shown in Figures 1-6 , an X-ray radiation shielding device includes a mounting frame and a shielding lead curtain 16 that is liftable and rotatable on the mounting frame. The mounting frame includes a fixed seat at the lower end and a sleeve 6 vertically installed on the fixed seat. A vertical rod 12 is inserted into the sleeve 6. A connecting sleeve 8 is fixedly provided at the upper end of the sleeve 6, and a damping sleeve 11 is provided between the connecting sleeve 8 and the vertical rod 12. A first cross bar 13 is provided at the upper end of the vertical rod 12, and the shielding lead curtain 16 is suspended on the first cross bar 13. The shielding device is installed on the edge of the examination table. When examining the upper limb joints, lower limb joints and other positions of the patient, the height of the shielding lead curtain 16 is adjusted according to the detected part, and the rotation of the shielding direction of the shielding lead curtain 16 is carried out according to the patient's position, and the adjustment is convenient and flexible.

[0031] In the X-ray radiation shielding device provided by the present utility model, the buckle plate 1 and the pressing plate 2 are connected together by a plurality of first connecting bolts 4, and the distance between the horizontal plate of the buckle plate 1 and the pressing plate 2 is adjustable, and it can be fixed on examination tables of different thicknesses.

[0032] As shown in Figure 4 , a through hole 801 that penetrates up and down and corresponds to the outer diameter of the vertical rod 12 is provided in the middle of the connecting sleeve 8. A sleeve slot 801 corresponding to the outer diameter of the sleeve 6 is provided in the lower part of the through hole 801. A clamping slot 803 is provided in the upper part of the through hole 801, and the damping sleeve 11 is clamped in the clamping slot 803. The clamping slot 803 is cylindrical and its diameter is larger than the diameter of the through hole 801. The damping sleeve 11 is made of rubber or silica gel, and its inner diameter is smaller than the outer diameter of the vertical rod 12 in the free state. By setting the connecting sleeve 8 and the damping sleeve 11, the vertical rod 12 can move up and down and rotate in the sleeve 6, and the position is fixed under the action of the damping sleeve 11, preventing the vertical rod 12 from lifting and rotating randomly, realizing the free switching function of the shielding lead curtain 16 in the bed position, and the adjustment is convenient and flexible.

[0033] A plurality of second countersunk holes 9 are evenly arranged circumferentially on the lower part of the side wall of the connecting sleeve 8. The second countersunk holes 9 are communicated with the sleeve slot 801, and second connecting bolts 10 are provided in the second countersunk holes 9. The connecting sleeve 8 is fastened to the upper end of the sleeve 6 through the second connecting bolts 10.

[0034] As shown in Figure 2As shown in the figure, the fixing base includes a buckle plate 1 in an L shape at the lower part and a pressing plate 2 horizontally arranged on the upper part of the buckle plate 1. A plurality of first countersunk holes 3 are formed at the edge of the pressing plate 2. A threaded hole corresponding to the first countersunk hole 3 is formed at the upper end of the vertical plate of the buckle plate 1. A first connecting bolt 4 is arranged in the first countersunk hole 3. A threaded part 601 is arranged at the lower part of the sleeve 6. A threaded hole corresponding to the lower part of the sleeve 6 is formed in the middle of the pressing plate 2. After the threaded part 601 is screwed into the threaded hole on the pressing plate 2, it is locked by a locking nut 7. As a further optimization, the threaded hole in the middle of the pressing plate 2 is a through hole, and the threaded part 601 at the lower end of the sleeve 6 passes through the threaded hole in the middle of the pressing plate 2 and can be abutted against the upper surface of the examination table, further realizing fastening.

[0035] Anti-slip pads 5 are arranged on the inner sides of the horizontal plate and the pressing plate 2 of the buckle plate 1; the anti-slip pads 5 are made of rubber or silica gel materials, so that the fixing base can be more firmly fixed on the edge of the examination table.

[0036] The shielding lead curtain 16 is made of radiation-proof fabric, and a sleeve 15 is arranged above it; the sleeve 15 is sleeved on the first cross bar 13; the shielding lead curtain 16 includes a shielding lead cloth at the upper part and a shielding curtain 20 at the bottom of the shielding lead cloth. The shielding curtain 20 is composed of a plurality of strip-shaped lead curtains that overlap with each other in the left-right direction and are arranged in sequence, and is used for the upper limb or lower limb of the patient to pass through. The lead curtain outside the limb can be placed on the examination table, and better radiation protection for other parts of the body can be achieved.

[0037] As a further optimization, the first cross bar 13 is a telescopable rod that can be manually adjusted. As a further optimization, a stop block 21 with a diameter larger than the size of the sleeve 15 is arranged at the free end of the telescopable rod to prevent the sleeve 15 from slipping off the first cross bar 13. As a further optimization, the vertical rod 12 and the cross bar are both hollow rods, and the stop block 21 is detachably plugged at the outer end of the cross bar.

[0038] Embodiment 2:

[0039] As Figures 7-9 shown in the figure, the difference between this embodiment and Embodiment 1 is that: the upper end of the vertical rod 12 is also connected to a second cross bar 14. The second cross bar 14 is arranged in parallel with the first cross bar 13 and at the same height. The first cross bar 13 is a telescopable rod that can be manually adjusted. The length of the second cross bar 14 is the same as the length of the first cross bar 13 when it is fully retracted; a shielding lead curtain 16 is respectively arranged on the first cross bar 13 and the second cross bar 14, and the two shielding lead curtains 16 are connected together by a magic tape. The width of one of the shielding lead curtains 16 is adapted to the length of the second cross bar 14, and the width of the other shielding lead curtain 16 is adapted to the length of the part of the first cross bar 13 that exceeds the second cross bar 14.

[0040] As a further optimization, a lapping portion 17 is provided at the inner end of the shielding lead curtain 16 on the first cross bar 13, and a sub surface 18 of a magic tape is provided on one side of the lapping portion 17. A mother surface 19 corresponding to the sub surface 18 is provided at the outer end of the shielding lead curtain 16 on the second cross bar 14.

[0041] For the shielding lead curtain 16 with a relatively large thickness, a relatively hard texture and not easy to be stacked and stored along the cross bar, by providing the retractable first cross bar 13 and the second cross bar 14, the two shielding lead curtains 16 are respectively located outside the first cross bar 13 and on the second cross bar 14, and are pasted together by the magic tape. When not in use, the first cross bar 13 is contracted to the shortest, and the shielding lead curtain 16 on the first cross bar 13 is pushed to the root of the first cross bar 13, which is convenient for realizing the storage of the shielding lead curtain 16.

[0042] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
