Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly defined otherwise. The embodiments described below by referring to the drawings are exemplary intended for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1, a lead-protecting screen according to an embodiment of the present invention includes a screen main body 1. The bottom of the screen main body 1 is provided with a plurality of moving parts, and the moving parts comprise an installation frame 2 and universal wheels 3 arranged on the installation frame 2. The screen main body 1 is also vertically provided with a slide rail 4, and the mounting rack 2 is connected on the slide rail 4 in a sliding way. The screen main body 1 is also provided with a driving device for driving the moving member to vertically move along the sliding rail 4, the driving device comprises a first fixed block 5 fixed on the screen main body 1 and an adjusting screw rod 6 vertically arranged and rotationally connected with the first fixed block 5, and the adjusting screw rod 6 is in threaded connection with the mounting frame 2. When needing to remove the lead screen, medical personnel can rotate adjusting screw 6 to make mounting bracket 2 along the vertical removal of slide rail 4, thereby make universal wheel 3 and ground contact, correspondingly, screen main part 1 receives the support of universal wheel 3 and breaks away from ground, and medical personnel can promote the lead screen and remove this moment. After moving to the designated position, the medical staff rotates the adjusting screw 6 reversely again, so that the screen main body 1 is lowered to be flush with the bottom of the universal wheel 3, and the lead screen can be fixed on the ground.

As shown in fig. 1 and 3, in this embodiment, in order to improve the stability of the lead screen when being fixed on the ground, a plurality of fixing brackets 7 are further arranged on two sides of the bottom of the screen main body 1, and the fixing brackets 7 are L-shaped rods; the vertical part of the folding screen is fixedly connected with the bottom of the folding screen main body 1 by bolts or welding and the like, and the horizontal part is provided with a supporting foot seat 71. When the lead screen is fixed on the ground, the support foot seat 71 contacts with the ground so as to support the whole lead screen. When the lead screen needs to be moved, the adjusting screw 6 is rotated, so that the universal wheel 3 moves downwards to contact the ground and replace the supporting foot seat 71 to support the whole lead screen, and at the moment, the supporting foot seat 71 is separated from the ground, so that the worker can move the lead screen. To further improve stability and protect the ground, the support foot 71 may be provided as a rubber block or a rubber pad (not shown) may be provided thereon to contact the ground.

As shown in fig. 1 and 3, in the present embodiment, the mounting frame 2 includes a horizontal bracket 21 and a vertical bracket 22 fixed to the horizontal bracket 21, and the universal wheels 3 are disposed at both ends of the horizontal bracket 21. The vertical bracket 22 is provided with a vertical mounting groove 23, and the bottom of the screen main body 1 is arranged in the mounting groove 23. The two sides of the bottom of the screen main body 1 are both fixedly provided with a slide rail 4, and the two inner sides of the mounting groove 23 are both connected with the screen main body 1 in a sliding way through the slide rail 4. Thus, when the adjusting screw 6 is rotated, the universal wheels 3 on two sides of the screen main body 1 can be synchronously lifted. In another embodiment, the mounting frames 2 can be provided as L-shaped rods such as the fixing brackets 7, and then the mounting frames 2 on both sides of the screen main body 1 are fixedly connected through connecting pieces, so that the linkage can be realized.

As shown in fig. 1 and 2, since the universal wheels 3 on both sides of the screen body 1 can be interlocked, the adjusting screw 6 is only required to be arranged on one side of the screen body 1. The adjusting screw 6 is preferably arranged on the side, back to the radiation, of the screen main body 1, namely the side where medical staff is located during use, so that the adjusting screw 6 can be prevented from polluting the gloves of the medical staff when being radiated, meanwhile, the medical staff does not need to walk to the radiation surface of the screen main body 1 to rotate the adjusting screw 6, and the safety is improved. In this embodiment, each driving device has two first fixing blocks 5 arranged at intervals, and the adjusting screw 6 is rotatably connected with the two first fixing blocks 5 through a bearing. The adjusting screws 6 are all provided with gears, chains 62 are wound among the gears among the adjusting screws 6, and the adjusting screws 6 are synchronously driven by the chains 62 (alternatively, belt wheel transmission and other transmission modes can be selected); medical personnel only need rotate an adjusting screw 6 like this, can realize carrying out synchronous vertical removal with all moving members, compare with this traditional mode of medical personnel's 3 universal wheels that need lock one by one, and the plumbous screen convenient operation of this application is efficient.

As shown in fig. 1, the adjusting screw rod 6 is further provided with a rotating handwheel 61, so that the adjusting screw rod 6 can be conveniently rotated by medical staff. The back radiation surface of the screen main body 1 is also provided with a pedal 8, and when in actual work, medical personnel generally sit on the chair and are positioned on the back radiation surface of the screen, and then record and observe through an observation window; the foot plate 8 can support the feet of the medical staff, and prevent the feet of the medical staff from being damaged by radiation when the rays pass through the gap between the screen main body 1 and the ground.

The utility model provides a lead screen has fine mobility, and the medical personnel of being convenient for switch the fixed and two kinds of states of removal of lead screen, have improved work efficiency.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
