Their performance directly affects the life and health of operators, public safety and environmental sustainability. With the innovation of medical imaging technology and the in-depth expansion of nuclear technology in energy, industrial testing and other fields, the types of radiation equipment are becoming increasingly diverse and the application scenarios are becoming more complex, which puts forward higher-dimensional requirements for the functionality, flexibility and intelligence of protection devices.
[0003] However, existing radiation protection devices are not convenient to adjust the height of the observation window according to the height of the operator, the location of the equipment, or the height of the radiation source. This makes it difficult to ensure that the operator can clearly observe the radiation area from a safe distance, thus reducing the versatility and practicality of the protection devices. Utility Model Content
[0004] The purpose of this utility model is to provide a radiation protection device. By setting up a height adjustment part, it solves the problem that existing radiation protection devices are not convenient to adjust the height of the observation window according to the height of the operator, the position of the equipment or the height of the radiation source, making it difficult to ensure that the operator can clearly observe the radiation area from a safe distance, thus reducing the versatility and practicality of the protection device.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a radiation protection device, including a protective shell, and also includes:
[0007] The protective part is disposed on the protective shell and is used to block radiation; the height adjustment part is installed inside the protective shell and extends outside the protective shell and is used to adjust the height; and the self-locking part is disposed on the protective shell and the height adjustment part; wherein the self-locking part is used to prevent the height adjustment part from rotating accidentally.
[0008] Furthermore, the protective part includes a protective plate slidably connected to the inner wall of the protective shell, and an observation window is provided on the protective plate; wherein, both the protective shell and the protective plate are made of lead material, and the glass of the observation window is made of inorganic high-lead glass containing mainly lead oxide.
[0009] Furthermore, the height adjustment unit includes an adjustment assembly installed inside the protective housing for raising and lowering the protective plate; and a transmission assembly disposed on the protective housing for transmitting operational power to the adjustment assembly; wherein the transmission assembly adjusts the height of the observation window by driving the protective plate to rise and fall.
[0010] Furthermore, the self-locking part includes a limiting component disposed on the rear side of the protective shell; and an elastic component disposed on the limiting component; wherein, the elastic component and the limiting component cooperate to ensure that the height adjustment part can only operate in one direction when the protective plate is raised.
[0011] Furthermore, the adjustment assembly includes a rotating shaft fixedly connected to the inner wall of the rear side of the protective shell, a gear rotatably connected to the outer wall of the rotating shaft, a slide rod fixedly connected to the front side of the gear, and a rectangular slide groove provided on the protective plate; wherein, the outer wall of the slide rod is slidably connected to the rectangular slide groove, and the rotation of the gear drives the slide rod to slide on the rectangular slide groove, thereby driving the protective plate to rise and fall.
[0012] Furthermore, the transmission assembly includes a second rotating shaft rotatably connected to the inner rear wall of the protective shell, a second gear fixedly connected to the outer wall of the second rotating shaft, and a knob fixedly connected to the rear side of the second rotating shaft; wherein, the rear side of the second rotating shaft extends to the outside of the protective shell, the second gear is fixedly connected to the outer inner wall of the second rotating shaft on the protective shell, the knob is fixedly connected to the rear extension of the second rotating shaft, and the second gear meshes with the first gear.
[0013] Furthermore, the limiting component includes a protective shell rotatably connected to the outer wall of the second rotating shaft. The inner wall of the protective shell is provided with several limiting grooves, and a turntable is fixedly connected to the outer wall of the second rotating shaft. The front side of the protective shell is fixedly connected to the protective shell. The protective shell is composed of a cylindrical shell and a circular cover. The circular cover is rotatably connected to the side of the cylindrical shell near the knob.
[0014] Furthermore, the elastic component includes a spring plate hinged to the rear side of the turntable, a limit rod hinged to the rear side of the turntable, a cylindrical rod fixedly connected to the rear side of the limit rod, and an arc-shaped groove on the protective shell, the inner wall of the arc-shaped groove contacting the cylindrical rod; wherein, the arc-shaped groove is formed on the circular cover of the protective shell, the limit rod is hinged to the spring plate, and the limit rod is adapted to several limit grooves.
[0015] This utility model has the following beneficial effects:
[0016] 1. By setting up a height adjustment unit, when adjusting the height, the knob is turned to rotate shaft two. Shaft two drives gear one to move on shaft one through gear two. Gear one drives the slide rod on it to rotate around shaft one. The slide rod drives the protective plate to rise through the rectangular slide groove, thereby raising the observation window on the protective plate. Conversely, after unlocking the self-locking part, the knob is turned in reverse to lower the observation window, thus achieving the purpose of adjusting the height of the observation window. This allows the height of the observation window to be flexibly adjusted according to the height of the operator, the position of the equipment, or the height of the radiation source, thereby ensuring that the operator can clearly observe the radiation area within a safe distance, improving the versatility and practicality of the protective device.
[0017] 2. By setting a self-locking part, when rotating shaft two, shaft two drives the limiting rod to rotate around shaft two via the turntable. The limiting rod is squeezed by the limiting groove it is in and rotates towards shaft two, causing the spring plate to be squeezed until the limiting rod enters the next limiting groove. The spring plate rebounds and locks it into the corresponding limiting groove, thus preventing shaft two from reversing. When the height adjustment part is released, simply slide the cylindrical rod along the arc groove to make it drive the limiting rod away from the limiting groove, and shaft two can be reversed. This can prevent the protective plate from falling accidentally due to accidental contact or equipment vibration, and avoid the observation window height from deviating from the safe range, thereby further ensuring that the operator can clearly observe the radiation area within a safe distance.

[0033] A specific application of this embodiment is as follows: When adjusting the height, the second rotating shaft 221 is rotated via knob 223. Rotating shaft 221, through gear 222, drives gear 1 212 to move on rotating shaft 211. Gear 1 212 drives the slide rod 213 on it to rotate around rotating shaft 211. The slide rod 213, through rectangular slide groove 214, causes the protective plate 112 to rise, thereby raising the observation window 113 on the protective plate 112. Conversely, after releasing the self-locking part 3, reversing knob 223 can lower the observation window 113, achieving the purpose of adjusting the height of the observation window 113. Rotating rotating shaft 223... At position 221, the second rotating shaft 221 drives the limiting rod 322 to rotate around the second rotating shaft 221 via the turntable 313. The limiting rod 322 is squeezed by the limiting groove 312 in which it is located and rotates towards the second rotating shaft 221, so that the spring plate 321 is squeezed until the limiting rod 322 enters the next limiting groove 312. The spring plate 321 rebounds and locks into the corresponding limiting groove 312, thereby preventing the second rotating shaft 221 from reversing. When the height adjustment part 2 is released, it is only necessary to slide the cylindrical rod 323 along the arc groove 324 to make it drive the limiting rod 322 away from the limiting groove 312, so that the second rotating shaft 221 can be reversed.
