Specific embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 shown, the present utility model provides a mobile anti-radiation lead screen, including a lead plate 1. An installation opening communicating front and back is opened above the front surface of the lead plate 1. An observation window 2 is fixedly connected inside the installation opening. The lower left and right sides of the front and back sides of the lead plate 1 are fixedly connected with connecting plates 3. A moving wheel 4 is movably connected to the side of the lower surface of the connecting plate 3 away from the lead plate 1. A limiting component 5 is fixedly connected to the opposite surfaces of the left and right connecting plates 3 in the front. Two adjusting components 7 are fixedly connected to the left and right sides of the lead plate 1 in a mirror image manner. Two driving components 6 are fixedly connected to the middle parts of the fronts of the two adjusting components 7 in a mirror image manner. The lead plate 1 and the adjusting component 7 are made of the same material;

[0027] Through the arrangement of the adjusting components 7 and the driving components 6 on the left and right, it is convenient to increase the overall width of the lead plate 1, so as to facilitate the adjustment effect. Through the arrangement of the limiting component 5, it is convenient to limit the position of the lead plate 1, preventing the phenomenon of position movement caused by the flexibility of the moving wheel 4 and accidental collision by others, and having a positioning effect.

[0028] As Figure 2 shown, both of the two adjusting components 7 include a sleeve plate 71. An adjusting plate 72 is slidably connected inside the sleeve plate 71. Anti-detachment grooves 73 are opened in the middle parts of the front and back inner walls of the sleeve plate 71. Blocking blocks are fixedly connected to the right sides of the front and back sides of the adjusting plate 72. The outer surface of the blocking block is slidably connected to the inside of the anti-detachment groove 73. A fixed block 74 is fixedly connected to the left side of the middle part of the front surface of the adjusting plate 72. Grooves are opened on the upper and lower surfaces of the right side of the adjusting plate 72. A roller is movably connected above the inside of the groove. The outer surface of the roller is in contact with the inner wall of the sleeve plate 71;

[0029] When in use, by setting the driving component 6, it is convenient to drive the adjusting plate 72 to move out from the inside of the sleeve plate 71, so that the blocking block slides inside the anti - detachment groove 73, thus facilitating the effect of position adjustment. Through the setting of the roller, it is convenient to roll when the adjusting plate 72 moves, reducing the phenomenon of friction and enhancing the flexibility effect.

[0030] As Figure 3 shown, both driving components 6 include a U - shaped plate 61 and a frame - shaped frame 65. The rear side of the frame - shaped frame 65 abuts against the front side of the sleeve plate 71. A number of tooth blocks 66 are fixedly connected to the opposite surfaces of the frame - shaped frame 65 in the horizontal direction. A plate 67 is fixedly connected to the left side of the frame - shaped frame 65 in the vertical direction, and the left side of the plate 67 is fixedly connected to the right side of the fixed block 74. Positioning plates 62 are fixedly connected to the rear sides of the opposite surfaces of the U - shaped plate 61 in the horizontal direction, and the rear sides of the positioning plates 62 abut against the front side of the frame - shaped frame 65. A micro - motor 63 is fixedly connected to the middle of the rear side of the U - shaped plate 61 in the vertical direction. The output shaft of the micro - motor 63 is fixedly connected with a semi - circular gear 64, and the outer surface of the semi - circular gear 64 is meshed with the outer surfaces of the upper and lower tooth blocks 66;

[0031] When the driving component 6 is in use, start the micro - motor 63 to drive the semi - circular gear 64 to rotate clockwise. Due to the meshing connection of the lower tooth block 66 in the frame - shaped frame 65, the frame - shaped frame 65 moves to the right. At this time, the tooth block in the semi - circular gear 64 is at the lower position. When the semi - circular gear 64 rotates to an appropriate position, the tooth block in the semi - circular gear 64 is at the upper position and meshes with the tooth block 66 in the upper part of the frame - shaped frame 65, thus pushing the frame - shaped frame 65 to move to the left and pushing the fixed block 74 to drive the adjusting plate 72 to move out from the inside of the sleeve plate 71. When it moves out to an appropriate position, the micro - motor 63 is turned off and stops working, thus facilitating the operation effect. Conversely, start the micro - motor 63 again to drive the semi - circular gear 64 to rotate, so that the tooth block in the semi - circular gear 64 contacts and meshes with the tooth block 66 in the lower part of the frame - shaped frame 65, driving the frame - shaped frame 65 to move and making the adjusting plate 72 contract inside the sleeve plate 71.

[0032] As Figure 4 - Figure 5As shown, the limit component 5 includes a mounting plate 51 and an anti-slip plate 54. In the middle of the upper surface of the mounting plate 51, a driving motor 52 is fixedly connected. On the left side of the upper surface of the mounting plate 51, a battery box 53 is fixedly connected. On the upper surface of the battery box 53, a switch box is fixedly connected. The output shaft of the driving motor 52 passes through the inside of the mounting plate 51 and is movably connected. The lower end of the output shaft of the driving motor 52 is fixedly connected with a pressing disc 58. On the upper surface of the anti-slip plate 54, four springs 55 are fixedly connected in a rectangular array. The upper ends of the four springs 55 are fixedly connected with the lower surface of the mounting plate 51. On the left and right sides of the upper surface of the anti-slip plate 54, telescopic shafts 56 are fixedly connected. The upper ends of the telescopic shafts 56 are fixedly connected with the lower surface of the mounting plate 51. The springs 55 and the telescopic shafts 56 are in a stretched state. On the front and rear sides of the middle of the upper surface of the anti-slip plate 54, trapezoidal blocks 57 are fixedly connected. The upper surface of the trapezoidal block 57 is in contact with the lower surface of the pressing disc 58. On the left and right sides of the outer surface of the trapezoidal block 57, rounded corners are arranged in a mirror image. On the left and right sides of the outer surface of the pressing disc 58, flat surfaces 581 are arranged. On the left and right sides of the upper surface of the anti-slip plate 54, heightening blocks 541 are fixedly connected;

[0033] Due to the electrical connection between the driving motor 52, the battery box 53, the switch box, and the micro motor 63 through wires, by starting the driving motor 52, the pressing disc 58 is driven to rotate. Due to the setting of the flat surface 581, it is convenient to press the two trapezoidal blocks 57 in the front and back, so that the springs 55 and the telescopic shafts 56 are stretched, and the anti-slip plate 54 moves downward and is in close contact with the ground. At this time, the lower surface of the pressing disc 58 is in contact with and presses against the upper surfaces of the trapezoidal blocks 57 in the front and back. At this time, the driving motor 52 stops working, thus achieving the anti-slip effect. On the contrary, when not in use, by starting the driving motor 52 again to drive the pressing disc 58 to rotate, the pressing disc 58 is separated from the upper surfaces of the trapezoidal blocks 57 in the front and back. Due to the action of the stretched springs 55, the anti-slip plate 54 moves upward and is separated from the ground. At this time, the telescopic shafts 56 contract, so that the left and right sides of the lower surface of the pressing disc 58 are in contact with the heightening blocks 541. At this time, the flat surface in the pressing disc 58 is in the left and right horizontal direction between the trapezoidal blocks 57 in the front and back. Through the setting of the heightening blocks 541, the phenomenon that the lower surface of the pressing disc 58 contacts the upper surface of the anti-slip plate 54 is prevented, so that the pressing disc 58 can better press the trapezoidal blocks 57 in the front and back when rotating.

[0034] Next, the working principle of the mobile anti-radiation lead screen will be specifically described.

[0035] Start the micro-motor 63 to drive the semi-circular gear 64 to rotate clockwise. When the semi-circular gear 64 rotates to an appropriate position, the tooth block in the semi-circular gear 64 is at the upper side and meshes with the tooth block 66 in the upper part of the frame 65, thereby pushing the frame 65 to move leftward and pushing the fixed block 74, driving the adjusting plate 72 to move out of the inner part of the sleeve plate 71, and then turning off the micro-motor 63 to facilitate the adjustment effect. By starting the driving motor 52 to drive the extrusion disc 58 to rotate, due to the setting of the plane 581, it is convenient to extrude the two trapezoidal blocks 57 before and after, stretching the spring 55 and the telescopic shaft 56, making the anti-slip plate 54 move downward and contact the ground tightly. At this time, the lower surface of the extrusion disc 58 contacts and presses against the upper surfaces of the trapezoidal blocks 57 before and after. At this time, the driving motor 52 stops working, thereby achieving the anti-slip effect.

[0036] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
