[0007] Furthermore, the slider is initially in conflict with the compression spring, and the compression spring is initially in a taut state. The slider is inserted into the slide groove to install the sticker, and the compression spring will pop the slider out of the slide groove when it rebounds.

[0008] Furthermore, the opening size of the slot is the same as the opening size of the groove, and one third of the arc block is in the slot in the initial state. The arc block is stuck in the slot so that the slider cannot leave the slot.

[0009] Furthermore, the arc surface of the arc block faces the opening direction of the slide groove, and the length of the groove is greater than the length of the arc block. When the arc surface of the arc block is squeezed, it will move into the groove, and the arc block can be completely retracted into the groove.

[0010] Furthermore, the deceleration mechanism includes a bracket, which is fixedly connected to the slider, and the inner side of the bracket is rotatably connected to a roller, the surface of the roller is provided with a square groove, the inside of the square groove is provided with an elastic rope, and the inside of the square groove is slidably connected to a resistance block through the elastic rope.

[0011] Furthermore, the bottom of the roller initially conflicts with the inner bottom of the slide, and the resistance block is made of rubber. When the roller moves following the slider through the bracket, its bottom will rub against the inner bottom of the slide, thereby rotating. When the rubber resistance block contacts the inner bottom of the slide, it will generate greater resistance.

[0012] Furthermore, the resistance block is completely located in the square groove in the initial state, and the resistance between the resistance block and the square groove is greater than the gravity of the resistance block itself, and the gravity of the resistance block itself will not cause the resistance block to move out of the square groove.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a mechanism for convenient disassembly of the blocks, so that the four groups of blocks can be firmly installed on the inner side of the protective shell through the cooperation of components such as sliders, slide grooves, card slots, and grooves. When the corresponding blocks need to be disassembled, only the pull rope needs to be pulled to make the blocks fall off. The installation and disassembly are simple and the inspection is convenient.

[0015] 2. The utility model is provided with a deceleration mechanism, so that the speed at which the slider moves out of the slide groove due to the rebound of the compression spring can be slowed down by the cooperation of components such as the bracket, roller, and square groove, thereby preventing the slider from moving out of the slide groove at too fast a speed due to the rebound of the compression spring, causing the sticker to fall off too quickly and directly fall to the ground, causing damage.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the initial state, the slider 92 conflicts with the compression spring 95, and the compression spring 95 is in a taut state. The slider 92 is inserted into the slide groove 94 to install the sticker 91. When the compression spring 95 rebounds, the slider 92 will pop out of the slide groove 94.

[0029] The opening size of the slot 93 is the same as that of the groove 96 , and one third of the arc block 98 is initially located in the slot 93 . The arc block 98 is stuck in the slot 93 so that the slider 92 cannot leave the slide groove 94 .

[0030] The arc surface of the arc block 98 faces the opening direction of the slide groove 94, and the length of the groove 96 is greater than the length of the arc block 98. When the arc surface of the arc block 98 is squeezed, it will move into the groove 96, and the arc block 98 can be completely retracted into the groove 96.

[0031] The deceleration mechanism 10 includes a bracket 101, which is fixedly connected to the slider 92. The inner side of the bracket 101 is rotatably connected to a roller 102. A square groove 103 is provided on the surface of the roller 102. An elastic rope 104 is provided inside the square groove 103. A resistance block 105 is slidably connected to the inside of the square groove 103 through the elastic rope 104.

[0032] In the initial state, the bottom of the roller 102 conflicts with the inner bottom of the slide groove 94. The resistance block 105 is made of rubber. When the roller 102 moves following the slider 92 through the bracket 101, its bottom will rub against the inner bottom of the slide groove 94 and rotate. When the rubber resistance block 105 contacts the inner bottom of the slide groove 94, it will generate greater resistance.

[0033] In the initial state, the resistance block 105 is completely in the square groove 103, and the resistance between the resistance block 105 and the square groove 103 is greater than the gravity of the resistance block 105 itself. The gravity of the resistance block 105 itself will not cause the resistance block 105 to move the square groove 103.

[0034] A specific application of this embodiment is as follows: a radioactive source storage port 6 is provided in the first protective block 3, a directional exposure head 7 is provided in the radioactive source storage port 6, the directional exposure head 7 is connected to a source delivery pipe 8, the radioactive source is input into the directional exposure head 7 through the source delivery pipe 8, the weld is detected and adjusted to a position where the front is aligned with the directional exposure head 7, four groups of detachable blocks 91 are provided on the other side of the front of the directional exposure head 7, when the corresponding block 91 needs to be removed according to the height of the weld, the pull rope at the corresponding block 91 is pulled outwards 99, the pull rope 99 is pulled to drive the arc block 98 to move downward, leave the card slot 93 and retract into the groove 96, the telescopic spring 97 is tightened, and when the arc block 98 leaves the card slot 93, the compression spring 95 will rebound and drive the slider 92 to move out of the slide slot 94, so that the block 91 here falls off. When the pull rope 99 is released, the telescopic spring 97 rebounds and drives the arc block 98 and the pull rope 99 to restore, thereby outputting the radiation according to the specified area and direction. When the block 91 here needs to be reinstalled, the slider 92 is inserted into the slide slot 9 4, the block 91 is installed, the compression spring 95 is squeezed and gradually tightened, and at the beginning, the arc surface of the arc block 98 is squeezed by the slider 92, which makes the arc block 98 gradually retract into the groove 96, and the telescopic spring 97 is tightened. When the groove 96 fits with the card slot 93, the telescopic spring 97 rebounds and drives the arc block 98 to be stuck in the card slot 93, so that the slider 92 cannot leave the slide 94, completing the installation of the block 91. The installation and disassembly are simple and convenient for detection. As the slider 92 moves, its bottom will rub against the inner bottom of the slide groove 94, causing it to rotate. When the compression spring 95 rebounds and drives the slider 92 to move out of the slide groove 94, if the speed is too fast, the rotation speed of the roller 102 will also increase. At this time, the centrifugal force generated by the rapid rotation of the roller 102 will throw the resistance block 105 out of the square groove 103 and contact the inner bottom of the slide groove 94 to generate greater resistance, thereby slowing down the speed of the slider 92 when it moves out of the slide groove 94, preventing the sticker 91 from falling off too quickly and directly falling to the ground and causing damage.
