DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example 1

[0026] See also Figure 1-5 The utility model provides a radiation protection device for high-precision X-ray sensitive components, including four radiation blocking frames 1, each of which is arranged in an "L"-shaped structure, and the interior of the four radiation blocking frames 1 is provided with an active cavity 2 for the movable adjustment of the extended radiation protection plate 5, and the two ends of the interior of the active cavity 2 are symmetrically fixedly connected with a flexible sheet 3, and one end of the flexible sheet 3 is fixedly connected with a first limiting protrusion 4 with a semi-cylindrical structure at equal intervals, the outer wall of the first limiting protrusion 4 conflicts with the outer wall of the second limiting protrusion 6, and the second limiting protrusion 6 is arranged in a semi-cylindrical structure, and the second limiting protrusion 6 is fixedly connected to the interior of the extended radiation protection plate 5 at equal intervals.

[0027] By setting up four radiation barrier frames 1, during use, the size of the high-precision X-ray sensitive components that require radiation protection can be adjusted accordingly. The specific adjustment method is that the two ends of the extended radiation protection plate 5 are respectively plugged into the interior of the radiation barrier frame 1, and then the radiation barrier frame 1 is expanded to both sides with the center point of the extended radiation protection plate 5, so that the device can be expanded into rectangles of different sizes. At the same time, according to needs, the radiation barrier frame 1 and the extended radiation protection plate 5 can be flexibly spliced ​​to form a "concave" structure setting, so that there are no limitations in the process of radiation protection of high-precision X-ray sensitive components. At the same time, after the adjustment of the radiation barrier frame 1 is completed, the flexible sheet 3 is reset, and the outer wall of the first limiting protrusion 4 is in conflict with the outer wall of the second limiting protrusion 6 to achieve self-limiting.

[0028] The outer sides of the radiation blocking frame 1 are tightly fitted and fixedly connected with a radiation protection component 7 having an "L"-shaped structure. The radiation protection component 7 includes a first protective film 701, a lead plate 702, and a second protective film 703. The outer walls on both sides of the lead plate 702 are fixedly connected with the first protective film 701 and the second protective film 703 respectively. The outer side walls of the first protective film 701 are fixedly connected to the outer side walls of the radiation blocking frame 1. The first protective film 701 and the second protective film 703 are both made of tungsten-plastic composite materials.

[0029] By setting up the radiation protection component 7, the radiation protection effect of the device can be further improved. The first and second protective films 701 and 703 made of double tungsten-plastic composite materials are combined with the lead plate 702 to effectively reduce the impact of X-rays.

[0030] The radiation protection component 7 is symmetrically fixedly connected to the outer wall away from the radiation blocking frame 1 with an installation cavity 8 and a female Velcro 16 with a velvet structure. The interior of the installation cavity 8 is symmetrically fixedly connected to a rotating cavity 9, and the interior of the rotating cavity 9 is horizontally rotatably connected to a rotating wheel 10. One end of the rotating wheel 10 is connected to an eddy current spring sheet 11 for resetting the rotating wheel 10, and a winding roller 12 is fixedly connected between the rotating wheels 10. The outer wall of the winding roller 12 is wound with a protective cloth 13, and one end of the protective cloth 13 passes through one side of the installation cavity 8 and is fixedly connected to one end of the limit end 14. The limit end 14 is fixedly connected to the outer wall of the radiation protection component 7 with a male Velcro 15 with a hook structure. The protective cloth 13 is made of lead powder or lead compound added to a rubber material.

[0031] After the radiation blocking frame 1 and the extended radiation protection plate 5 are flexibly spliced ​​and combined, according to the use requirements, one end of the limiting end 14 can be installed through the protective cloth 13 and moved outward until the limiting end 14 is adhered to each other through the outer wall of the male Velcro 15 and the female Velcro 16, thereby limiting the protective cloth 13 and the limiting end 14. At this time, the protective cloth 13 is covered on the outside of the extended radiation protection plate 5, thereby further protecting the extended radiation protection plate 5 from radiation, and effectively avoiding the problem of reduced service life of sensitive components due to radiation intensity.

[0032] The outer side walls of the radiation protection component 7 away from the radiation barrier frame 1 are fixedly connected with the plug-in cavity 17, and the inside of the plug-in cavity 17 is plugged with a plug-in block 18, the bottom end of the plug-in block 18 is fixedly connected with a linkage plate 19, and one side of the linkage plate 19 is fixedly connected to the outer side wall of the transmission screw sleeve 20, the transmission screw sleeve 20 is penetrated and engaged with the connecting screw 21, the connecting screw 21 and the transmission screw sleeve 20 constitute a screw transmission structure, and the top of the connecting screw 21 is fixedly connected to the output end of the motor 23, the motor 23 is fixedly connected to the top of the fixed frame 22, the vertical outer wall of the fixed frame 22 is vertically sleeved with a movable sleeve 24, and the movable sleeve 24 is movably connected to the vertical outer wall of the fixed frame 22, the outer side wall of the connecting screw 21 is engaged with a limit block 25 for limiting the movement of the transmission screw sleeve 20.

[0033] A screw transmission structure is formed by the provided connecting screw 21 and the transmission screw sleeve 20. In this way, when the radiation protection structure composed of the radiation barrier frame 1 and the extended radiation protection plate 5 needs to be raised or lowered during use, the motor 23 outputs and drives the connecting screw 21 to rotate forward or reverse, thereby driving the connecting screw 21 to rotate forward or reverse. In this way, the transmission screw sleeve 20 drives the plug-in block 18 and the linkage plate 19 to rise and fall vertically, thereby driving the radiation protection structure composed of the radiation barrier frame 1 and the extended radiation protection plate 5 to rise and fall according to demand. This method has the advantage of high stability and effectively avoids unstable collisions with the components to be protected during the lifting process.

[0034] The specific usage process of this embodiment is:

[0035] First, measurements are taken based on the sensitive components to be protected from radiation to obtain the optimal dimensional parameter data for the protective structure. The two ends of the extended radiation protection plate 5 are then inserted into the interior of the radiation barrier frame 1. The radiation barrier frame 1 is then extended from the center point of the extended radiation protection plate 5 to both sides. This allows the device to be expanded into protective structures of varying sizes to suit the sensitive components to be protected from radiation.

[0036] Secondly, after the radiation blocking frame 1 and the extended radiation protection plate 5 are flexibly spliced ​​and assembled, according to the use requirements, one end of the protective cloth 13 with the limit end 14 can be moved outward until the limit end 14 is adhered to the outer wall of the female Velcro 16 through the male Velcro 15, thereby limiting the position of the protective cloth 13 and the limit end 14. At this time, the protective cloth 13 is covered on the outside of the extended radiation protection plate 5, thereby further protecting the extended radiation protection plate 5 from radiation;

[0037] Then, according to the free area of ​​the device, the fixing frame 22 is fixed by bolts and other components, and the plug-in block 18 is plugged into the corresponding plug-in cavity 17. In this way, in daily use, the output of the motor 23 drives the connecting screw 21 to rotate forward or reverse, thereby driving the connecting screw 21 to rotate forward or reverse. This, in conjunction with the transmission screw sleeve 20, drives the plug-in block 18 and the linkage plate 19 to move vertically, thereby driving the radiation protection structure composed of the radiation blocking frame 1 and the extended radiation protection plate 5 to move up and down as needed;

[0038] Finally, by combining the first and second protective films 701 and 703 made of a tungsten-plastic composite material with the lead plate 702, the effects of X-rays are effectively reduced, and a high-precision radiation protection device for X-ray sensitive components is thus completed.
