Description

Technical Field

[0001] This utility model relates to the field of radiation protection monitoring technology, specifically a portable radiation protection monitoring device. Background Technology

[0002] Radioactive detection refers to the safety inspection of machines or construction sites that can produce ionizing radiation or electromagnetic radiation. Radioactive materials are extremely harmful to the human body, so in some environments, it is often necessary to use a monitoring device to monitor radioactivity. Existing portable radiation monitoring instruments are not convenient to carry when conducting radiation detection, requiring personnel to hold them at all times, and the protection of the monitoring instrument itself is not good.

[0003] According to a novelty search report, CN222330402U discloses a portable radiation protection monitoring device, including a protective mechanism. The protective mechanism has an internal mounting slot, and fixing mechanisms are fixedly installed on both the upper and lower sides of the mounting slot. A monitoring device body located within the mounting slot is movably engaged with the inner side of each fixing mechanism. The protective mechanism includes a fixed housing, and a cover plate is movably hinged to the lower outer side of the fixed housing. By using the protective mechanism to install the monitoring device body in the mounting slot within the protective mechanism, the external structure of the monitoring device body is shielded and protected. In the event of an accidental drop, the protective mechanism absorbs and cushions the impact outside the monitoring device body, thereby reducing damage to the monitoring device body inside the protective mechanism and preventing damage to the monitoring device body.

[0004] The aforementioned portable radiation protection monitoring device, through its fixed housing and forward-rotating cover, provides secure protection for the monitoring unit when not in use. Its rear-mounted fixed structure facilitates hand-free carrying. However, it suffers from the following drawbacks in practical use: 1. The long cover, when flipped forward, significantly increases the overall size of the device, hindering carrying during personnel movement and reducing ease of use; 2. The forward-flipped cover is prone to swaying due to personnel movement during inspection, reducing stability during use. Therefore, this application proposes a portable radiation protection monitoring device to address these problems. Utility Model Content

A limb binding assembly is installed on the rear side of the protective shell. The limb binding assembly is used to conveniently bind the protective shell to the arm of the radiation monitoring personnel, so as to free their hands for convenient carrying and detection work during radiation monitoring.

[0007] Both sides of the protective shell are fixedly connected to swivel assemblies. The sides of the two swivel assemblies that are close to each other are fixedly connected to transparent cover plates that are in movable contact with the front side of the protective shell. The top front side of the protective shell is fixedly connected to a fixed box with an open bottom. The top inner wall of the fixed box is rotatably mounted with a linkage rotary drive assembly for driving the two swivel assemblies to rotate synchronously relative to each other. The right side of the linkage rotary drive assembly is fixedly connected to a rotary locking assembly for driving its rotation and locking it. The rotary locking assembly is used to allow personnel to easily drive the linkage rotary drive assembly to rotate and lock it after rotation. The linkage rotary drive assembly is used to drive the two swivel assemblies to rotate relative to each other during rotation. The two rotation assemblies are used to drive the two transparent cover plates to flip and fold to the sides of the protective shell or to rotate back and shield for protection.

[0008] Preferably, the limb binding assembly includes two first binding straps fixedly connected to the right rear side of the protective shell, and two second binding straps fixedly connected to the left rear side of the protective shell. A female Velcro is sewn onto the left side of the second binding strap, and a male Velcro that mates with the corresponding female Velcro is sewn onto the top left side of the first binding strap.

[0009] Preferably, the swivel assembly includes two fixed sleeves. The top and bottom sides of the protective shell are respectively fixedly connected to the outer side of the corresponding fixed sleeve. The same rotating shaft is rotatably fitted inside the two upper and lower opposite fixed sleeves. A circular sleeve is fixedly fitted on the rotating shaft. The side of the two circular sleeves that are close to each other is fixedly connected to the side of the two transparent cover plates that are in opposition. The top end of the rotating shaft extends into the fixed box.

[0010] Preferably, the linkage rotary drive assembly includes a linkage shaft rotatably mounted on the inner wall of the top of the fixed box. Both ends of the linkage shaft are fixedly connected to a first bevel gear. The two first bevel gears are symmetrically arranged. A second bevel gear meshes with the repulsive side of each of the two first bevel gears. The bottom of each of the two second bevel gears is fixedly connected to the top of the corresponding rotating shaft.

[0011] Preferably, the rotary locking assembly includes a square tube fixedly connected to the right side of the first bevel gear on the right side and having a sealing structure at the left end. A square rod is slidably sleeved inside the square tube. The right end of the square rod extends to the outside of the fixing box and is fixedly connected to a knob. A compression spring in a compressed state is fixedly connected between the left end of the square rod and the inner wall of the left end of the square tube. A hard anti-slip rubber ring is fixedly connected to the inner wall of the right side of the fixing box. L-shaped pointed blocks are fixedly connected to the top, bottom, front, and rear sides of the square rod. The right end of the L-shaped pointed block has a conical structure and is pressed tightly against the left side of the hard anti-slip rubber ring.

[0012] Preferably, a sponge pad is bonded to the rear side of the protective shell, and the sponge pad is located between the first strap and the second strap.

[0013] Preferably, a circular perforation is provided on the inner right side of the fixing box, and the square rod is located inside the circular perforation and the hard anti-slip rubber ring without contacting the inner side of either of them.

[0015] 1. With the combination of the arm and limb securing components and the protective shell, the protective shell can be easily and quickly secured to the arm of the radiation monitoring personnel, making it convenient for personnel to carry and use the radiation monitoring instrument without holding it by hand;

[0016] 2. Through the combination of the protective shell, fixing box, transparent cover, rotating support assembly, linkage rotating drive assembly, and rotating locking assembly, the two transparent covers can be easily rotated and folded to overlap and lock on both sides of the protective shell by pushing and rotating. By folding to the sides and overlapping, the transparent covers do not occupy a lot of space on the front side when opened, which affects the carrying. This makes the size more compact and improves the carrying convenience. Moreover, by locking them directly after opening and folding, the covers do not swing due to personnel movement or shaking during inspection, which improves the stability of carrying and use.

[0017] This utility model features a series of structures that allow for convenient and quick attachment of the protective shell to the arm of radiation monitoring personnel, enabling them to carry and use the radiation monitoring instrument without hands. Furthermore, the two transparent covers can be easily rotated and folded to overlap and lock onto both sides of the protective shell. This overlapping folding method reduces the size of the device, improving portability. The integrated locking mechanism after folding prevents swaying during personnel movement, enhancing stability during use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this embodiment proposes a portable radiation protection monitoring device, including a protective shell 1 with an opening on the front and a radiation monitoring instrument 2 disposed inside the protective shell 1. L-shaped shock-absorbing rubber blocks 201 are glued and fixed between the four inner corners of the protective shell 1 and the four outer corners of the radiation monitoring instrument 2, respectively. A limb binding assembly is installed on the rear side of the protective shell 1. The limb binding assembly is used to conveniently bind the protective shell 1 to the arm of the radiation monitoring personnel, so as to free their hands for convenient carrying and detection work during radiation monitoring.

[0026] Both sides of the protective shell 1 are fixedly connected to swivel assemblies. The sides of the two swivel assemblies that are close to each other are fixedly connected to transparent cover plates 3 that are in movable contact with the front side of the protective shell 1. The top front side of the protective shell 1 is fixedly connected to a fixed box 6 with an open bottom. The top inner wall of the fixed box 6 is rotatably mounted with a linkage rotary drive assembly for driving the two swivel assemblies to rotate synchronously relative to each other. The right side of the linkage rotary drive assembly is fixedly connected to a rotary locking assembly for driving its rotation and locking it. The rotary locking assembly is used to allow personnel to easily drive the linkage rotary drive assembly to rotate and lock it after rotation. The linkage rotary drive assembly is used to drive the two swivel assemblies to rotate relative to each other when rotating. The two rotation assemblies are used to drive the two transparent cover plates 3 to flip and fold to the sides of the protective shell 1 or to rotate back and shield for protection.

[0027] Specifically, the limb binding assembly includes two first binding straps 101 fixedly connected to the right rear side of the protective shell 1, and two second binding straps 102 fixedly connected to the left rear side of the protective shell 1. Female Velcro 103s are sewn onto the left side of each second binding strap 102, and male Velcro 104s that mate with the corresponding female Velcro 103s are sewn onto the top left side of each of the first binding straps 101. A sponge pad is adhesively fixed to the rear side of the protective shell 1, located between the first binding straps 101 and the second binding straps 102. The sponge pad is used to secure the limbs to the rear side of the protective shell 1 during binding. The system provides flexible support for the personnel's arms, reducing discomfort caused by rigid compression. The first strap 101, the second strap 102, the female Velcro 103, and the male Velcro 104 work together to wrap the second strap 102 around the radiation monitoring personnel's arms. Then, the first strap 101 is pulled tight and wrapped around the outside of the corresponding second strap 102. The male Velcro 104 on the first strap 101 is then bonded to the corresponding female Velcro 103. By using this bonding method, the protective shell 1 can be conveniently and quickly secured to the radiation monitoring personnel's arms.

[0028] Furthermore, the rotating support assembly includes two fixed sleeves 301. The top and bottom sides of the protective shell 1 are respectively fixedly connected to the outer sides of the corresponding fixed sleeves 301. The same rotating shaft 302 is rotatably fitted inside the two upper and lower opposing fixed sleeves 301. A first bearing is fixedly fitted between the inner side of the fixed sleeve 301 and the outer side of the corresponding rotating shaft 302, and the rotating shaft 302 is rotatably mounted using the first bearing. A circular sleeve 303 is fixedly fitted on the rotating shaft 302. The adjacent sides of the two circular sleeves 303 are respectively fixedly connected to the opposing sides of the two transparent cover plates 3. The top end of the rotating shaft 302 extends into the fixed box 6. The fixed sleeves 301 and the rotating shaft 302 are provided with a rotating support assembly. The shaft 302 and the circular sleeve 303 cooperate to rotate and install the transparent cover 3 through the corresponding circular sleeve 303. When the two shafts 302 rotate relative to each other, the two circular sleeves 303 drive the two transparent cover 3 to rotate repulsively or rotate relative to each other. The repulsive rotation of the two transparent cover 3 can be rotated and folded to the two sides of the protective shell 1 for overlap, which can easily avoid the phenomenon of occupying too much space on the front side and affecting the use when opening for testing. In addition, after the two transparent cover 3 rotates and closes, it cooperates with the protective shell 1 to protect the radiation monitor 2 when it is not in use, reduce the risk of accidental damage when it is not in use, and ensure the safety of carrying it.

[0029] Furthermore, the linkage rotary drive assembly includes a linkage shaft 4 rotatably mounted on the inner wall of the top of the fixed box 6. Two second bearings are fixedly mounted on the inner wall of the top of the fixed box 6. The inner rings of the second bearings are fixedly fitted to the outer side of the linkage shaft 4, which serves to rotatably mount the linkage shaft 4. Both ends of the linkage shaft 4 are fixedly connected to first bevel gears 401. The two first bevel gears 401 are symmetrically arranged. The two repulsive sides of the two first bevel gears 401 are meshed with second bevel gears 402. The bottoms of the two second bevel gears 402 are fixedly connected to the tops of the corresponding rotating shafts 302. The linkage shaft 4, the first bevel gears 401 and the second bevel gears 402 cooperate. When the first bevel gear 401 on the right rotates, it will drive the first bevel gear 401 on the left to rotate synchronously through the linkage shaft 4. Since the two first bevel gears 401 are symmetrically arranged, when the two first bevel gears 401 rotate, they can drive the two second bevel gears 402 to rotate in opposite directions. The opposite rotation of the two first bevel gears 401 drives the two rotating shafts 302 to rotate relative to each other.

[0030] Furthermore, the rotary locking assembly includes a square tube 5 fixedly connected to the right side of the first bevel gear 401 on the right side, with a sealing structure at the left end. A square rod 501 is slidably sleeved inside the square tube 5. The right end of the square rod 501 extends to the outside of the fixing box 6 and is fixedly connected to a knob 502. A compression spring 503 in a compressed state is fixedly connected between the left end of the square rod 501 and the inner wall of the left end of the square tube 5. A hard anti-slip rubber ring 505 is fixedly connected to the inner wall of the right side of the fixing box 6. A circular through hole is provided on the inner right side of the fixing box 6. The square rod 501 is located inside the circular through hole and the hard anti-slip rubber ring 505 without contacting the inner sides of either of them, thus allowing the square rod 501 to pass through. L-shaped pointed blocks 504 are fixedly connected to the top, bottom, front, and rear sides of the square rod 501. The right end of the L-shaped pointed block 504 has a conical structure and is pressed tightly against the left side of the hard anti-slip rubber ring 505. The square tube 5, square rod 501, knob 502, and compression spring are also provided. 503. The hard anti-slip rubber ring 505 and the L-shaped pointed block 504 cooperate to push the knob 502 to the left, causing the square rod 501 to slide to the left inside the square tube 5, compressing the compression spring 503. The square rod 501 drives the four L-shaped pointed blocks 504 to the left, separating from the hard anti-slip rubber ring 505 and releasing the squeezing and fixing state. Rotating the knob 502 drives the square rod 501 to rotate. Utilizing the characteristic of the square part having sharp corners that fit together, the square rod 501 rotates, driving the square tube... 5. Rotation of the square tube 5 drives the first bevel gear 401 on the right side to rotate. When the force of the knob 502 is released to the left, the elastic force of the compression spring 503 in the compressed state drives the square rod 501 to move back to the right. The square rod 501 drives the L-shaped pointed block 504 to the right to squeeze and lock with the left side of the hard anti-slip rubber ring 505. This allows for convenient unlocking and locking of the first bevel gear 401 by pushing and rotating and releasing the knob.

[0031] The method of using this embodiment is as follows: When using the portable radiation protection monitoring device, the second strap 102 is wrapped around the arm of the radiation monitoring personnel, and the first strap 101 is pulled tight and wrapped around the outside of the corresponding second strap 102. The male Velcro 104 on the first strap 101 is then attached to the corresponding female Velcro 103. By using the attachment method, the protective shell 1 can be conveniently and quickly secured to the arm of the radiation monitoring personnel, making it convenient for personnel to carry and use without holding their hands.

[0032] When the transparent cover 3 needs to be opened to operate the radiation monitoring instrument 2 for radiation detection, first push the knob 502 to the left to make the square rod 501 slide to the left inside the square tube 5, compressing the compression spring 503. The square rod 501 drives the four L-shaped pointed blocks 504 to the left to separate from the hard anti-slip rubber ring 505, releasing the squeezed and fixed state. Rotate the knob 502 to drive the square rod 501 to rotate. Utilizing the characteristic of the square part having sharp corners that fit the photo clip, the square rod 501 rotates, driving the square tube 5 to rotate. The square tube 5 drives the first bevel gear 401 on the right to rotate. When the first bevel gear 401 on the right rotates, it will drive the first bevel gear 401 on the left to rotate synchronously through the linkage shaft 4. Since the two first bevel gears 401 are symmetrically arranged, when the two first bevel gears 401 rotate, they can drive the two second bevel gears 402 to rotate in opposite directions. The opposite rotation of the two first bevel gears 401 drives the two rotating shafts 302 to rotate relative to each other. When the two rotating shafts 302 rotate relative to each other, they are driven by the two round sleeves 303. The two transparent covers 3 rotate against each other, causing them to gradually rotate and fold to overlap on both sides of the protective shell 1. Then, the push force on the knob 502 is released. At this time, the compression spring 503, which is in a compressed state, causes the square rod 501 to move back to the right. The square rod 501 causes the L-shaped pointed block 504 to squeeze and lock to the left side of the hard anti-slip rubber ring 505, thus restricting the square rod 501 from rotating further. This locks the transparent covers 3 that have been rotated and folded to both sides. This allows for easy rotation and folding of the two transparent covers 3 to overlap and lock on both sides of the protective shell 1. By folding them to the sides and overlapping them, the problem of the transparent covers 3 occupying a lot of space on the front side when opened is avoided, making the size more compact and improving portability. Furthermore, by locking them together after opening and folding, the problem of swaying due to personnel movement during inspection is avoided, thus improving the stability of carrying and use.

[0033] After use, push the knob 502 to the left again. The movement process is the same as pushing the knob 502 as described above. Unlock the device again. Then rotate the knob 502 back. The movement direction is completely opposite to that of rotating the knob 502 as described above. At this time, the two transparent covers 3 rotate synchronously to the front of the protective shell 1 to seal and protect the radiation monitor 2. This reduces the risk of accidental damage when the device is not in use. The four L-shaped shock-absorbing rubber blocks 201 provide flexible shock absorption protection for the radiation monitor 2 when it is carried.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
