[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a regional radiation dose monitor, including a protective seat 1, the inner wall of the left end of the protective seat 1 is elastically connected to a connecting block 3 through a reset spring 2, a notch is provided on the protective seat 1, and the connecting block 3 can move laterally along the inner wall of the notch, and the top of the connecting block 3 is fixedly connected to a protective frame 4, and the top of the protective frame 4 is made of transparent material, and the data displayed by the internal monitor body 9 can be observed from the outside, and the inner wall of the protective seat 1 is provided with a guide mechanism, referring to Figure 4The inner wall of the right end of the connecting block 3 is elastically connected to the limiting block 7 through a movable spring 6. The left end of the limiting block 7 is a large inclined surface, which can allow the notch of the side wall of the protective seat 1 to squeeze the large inclined surface, allowing the limiting block 7 to slide along the inner wall of the connecting block 3, and the right end of the limiting block 7 is a small inclined surface, and the right end of the limiting block 7 and the small inclined surface of the notch of the side wall of the protective seat 1 are in a blocked state. The limiting block 7 needs to be pressed to allow the small inclined surface to be squeezed, and the inner wall of the bottom end of the protective seat 1 is elastically connected to the monitoring instrument body 9 through a positioning spring 8.

[0035] Reference Figure 5-Figure 6 The side wall of the monitor body 9 is fixedly connected with a fixing plate 10, and a connecting pipe 11 is inserted in the middle of the fixing plate 10. The inner wall of the connecting pipe 11 is elastically connected with a rotating plate 13 through a torsion spring 12. The rotating plate 13 is in a straight line shape, which allows the rotating plate 13 to overlap with the notch on the fixing plate 10, so that the fixing plate 10 can fall off the connecting pipe 11. The outer wall of the connecting pipe 11 is fixedly connected with a protrusion 14, which is made of rubber material and can generate a certain resistance to slow down the vibration when the fixing plate 10 moves vertically. The inner wall of the connecting pipe 11 is fixedly connected to one end of the torsion spring 12. At this time, the torsion spring 12 is in the initial state. When the rotating plate When 13 rotates clockwise, the torsion spring 12 will be compressed. When resetting, the elastic force of the torsion spring 12 is used to reset the rotating plate 13. The other end of the torsion spring 12 is fixedly connected to the outer wall of the rotating plate 13. The rotating plate 13 is rotatably connected to the inner wall of the connecting tube 11. The protrusion 14 contacts the inner wall of the fixed plate 10. The fixed plate 10 is provided with an opening, which allows the opening surface to generate friction with the protrusion 14. The connecting tube 11 is fixedly connected to the inner wall of the bottom end of the protective seat 1, and the fixed plate 10 contacts the outer wall of the rotating plate 13. During the installation process of the fixed plate 10 and the monitor body 9, the rotating plate 13 will contact the inner wall of the fixed plate 10 in a straight line.

[0036] Reference Figure 1-Figure 3 The inner wall of the bottom end of the protective seat 1 is fixedly connected to one end of the positioning spring 8. Since the monitor body 9 has a certain gravity, the positioning spring 8 is compressed at this time. When the monitor body 9 moves out of the protective seat 1, it resets itself by utilizing the elastic force of the positioning spring 8. The other end of the positioning spring 8 contacts the bottom end of the monitor body 9. The inner wall of the left end of the protective seat 1 is fixedly connected to one end of the reset spring 2. When the connecting block 3 moves to the left, the reset spring 2 will be compressed. When resetting, the elastic force of the reset spring 2 is used to reset the connecting block 3. The other end of the reset spring 2 is fixedly connected to the left end of the connecting block 3. The connecting block 3 is slidably connected to the inner wall of the protective seat 1. Figure 4The inner wall of the right end of the connecting block 3 is fixedly connected with one end of the movable spring 6. When the limit block 7 moves to the right, the movable spring 6 will be compressed. When resetting, the elastic force of the movable spring 6 is used to restore the limit block 7. The other end of the movable spring 6 is fixedly connected to the outer wall of the limit block 7. The limit block 7 is plugged into the side wall of the protective seat 1. The side wall notches of the protective seat 1 are divided into two groups. The position distribution of the two groups of notches is different. After the protective frame 4 moves, the limit block 7 is plugged with it for positioning. The protective seat 1 contacts the bottom end of the protective frame 4. The protective seat 1 and the protective frame 4 are used together to form a protective device specifically for the monitor body 9. The guide mechanism includes a guide tube 5, which is fixedly connected to the inner wall of the protective seat 1. The guide tube 5 is slidably connected to the middle part of the connecting block 3. The guide tube 5 can move horizontally with the connecting block 3 by the horizontal protective frame 4, and will not cause a large deformation of the reset spring 2.

[0037] Working principle: First, when you need to use the monitor body 9, Figure 1 As shown, it is only necessary to push the protection frame 4 to the left so that the side wall of the protection seat 1 squeezes the small inclined surface at the left end of the limit block 7, so that the limit block 7 moves to the right and compresses the movable spring 6, so that the protection frame 4 moves to the left with the connecting block 3 and the limit block 7. When the limit block 7 coincides with the notch of the other set of side walls of the protection seat 1, the reverse elastic force of the movable spring 6 is used to reset the limit block 7, so that the limit block 7 is plugged into the notch of the side wall of the protection seat 1, and the right end surface of the limit block 7 blocks the entire connecting block 3 and the protection frame 4 from moving to the right, as shown in FIG. Figure 2 As shown, the monitor body 9 can then be operated to monitor the surrounding radiation. When the monitor body 9 is not in use, it is only necessary to press the limit block 7 so that the small inclined surface at the right end of the limit block 7 can be squeezed by the side wall notch of the protective seat 1. At this time, the reverse elastic force of the reset spring 2 is used to reset the connecting block 3 and the protective frame 4 to the right, so that the protective frame 4 returns to the position as shown in FIG. Figure 1 As shown, the limit block 7 is again overlapped and plugged into the side wall groove of the protective seat 1. Since the elastic force of the reset spring 2 itself is not affected by the manual squeezing of the protective frame 4, the large inclined surface at the left end of the limit block 7 will not be squeezed. The protective seat 1 and the protective frame 4 cooperate to protect the monitor body 9 and achieve the purpose of dust prevention.

[0038] When the monitor body 9 needs to be disassembled, it is only necessary to open the protective frame 4 as described in the first paragraph, then rotate the rotating plate 13 and compress the torsion spring 12 to overlap the notch of the rotating plate 13 and the fixed plate 10, and then move the fixed plate 10 out from the outer wall of the connecting tube 11 through the monitor body 9. Since the monitor body 9 is not in contact with the positioning spring 8, the positioning spring 8 will reset itself. When the monitor body 9 needs to be installed, it is only necessary to connect the fixed plate 10 with the outer wall of the connecting tube 11. When the notch of the fixed plate 10 and the rotating plate 13 pass through, release the rotating plate 13 and use the reverse elastic force of the torsion spring 12 to reset the rotating plate 13, so that the notches of the rotating plate 13 and the fixed plate 10 are separated, so that the fixed plate 10 cannot be detached from the top of the connecting tube 11.

[0039] When a collision or vibration occurs, the positioning spring 8 will continue to compress or reset, allowing the monitor body 9 to slide along the outer wall of the connecting tube 11 with the fixing plate 10. The friction between the protrusion 14 and the inner wall of the fixing plate 10 can reduce the vibration to a certain extent, and the elastic force of the positioning spring 8 itself can reduce part of the vibration.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
