[0040] See also Figure 1 An embodiment of the present invention provides a radioactive contaminant protective glove 100, comprising a glove body 10, a flexible fixing device 20 and a locking device 30. The glove body 10 comprises a palm portion 11 and an arm portion 12. The flexible fixing device 20 is arranged around the arm portion 12 and is slidably connected to the arm portion 12 along the longitudinal direction of the arm portion 12. The flexible fixing device 20 has a first opening end 21 and a second opening end 22 that form an opening.

[0041] It should be pointed out that the palm portion 11 in the present application refers to a component that can be mounted on the palm and fingers of a human body, and the arm portion 12 in the present application refers to a component that can be mounted on at least part of the arm of a human body.

[0042] It should also be pointed out that the flexible fixing device 20 in the present application refers to a device that can be bent, twisted or deformed without losing performance, so that the flexible fixing device 20 can adjust its radial size by the first open end 21 and the second open end 22. Preferably, the flexible fixing device 20 can be made of a resilient hard rubber material, so that it fits the arm better and is not easy to loosen.

[0043] like Figure 4As shown, the locking device 30 includes a locking member 31 and a matching member 32, the locking member 31 is arranged at the first opening end 21, and the matching member 32 is arranged at the second opening end 22, the locking member 31 includes an unlocking position separated from the matching member 32 and a locking position matched with the matching member 32 to close the opening, wherein the locking position includes multiple locking positions, and the distance between the first opening end 21 and the second opening end 22 corresponding to each locking position is different.

[0044] The radioactive contaminant protection glove 100 of the present application is provided with a flexible fixing device 20 with an opening between the palm portion 11 and the arm portion 12, and the first opening end 21 and the second opening end 22 are locked by a locking device 30 to adjust the distance between the first opening end 21 and the second opening end 22, thereby adjusting the radial dimension of the flexible fixing device 20, so that the flexible fixing device 20 can reliably fix the radioactive contaminant protection glove 100 on the palm and arm of the worker, thereby preventing the radioactive contaminant protection glove 100 from loosening.

[0045] In some embodiments, the palm portion 11 includes five stacked material layers, the first layer is a radiation-proof isolation layer, which can be made of silicone rubber as the main material, the second layer is an airtight layer, which can be made of butyl rubber as the main material, the third layer is a reinforcement layer, which can be made of nylon braid as the main material, the fourth layer is an anti-penetration layer, which can be made of butyl rubber and an anti-penetration agent, and the fifth layer is an isolation layer, which can be made of silicone rubber and a metal film. The first material layer to the fifth material layer are stacked from the inside to the outside. In other embodiments, the arm portion 12 may also include the above-mentioned five stacked material layers. In this way, the palm portion 11 and the arm portion 12 have good radiation and penetration protection effects. Further, at least one of the palm portion 11 and the arm portion 12 also includes a sixth shielding layer, which is made of lead material to enhance the safety protection of the staff.

[0046] Please refer again Figure 1 In some embodiments, a zipper 121 and a zipper 122 matched with the zipper 121 are provided along the axial direction of the arm portion 12. Thus, when the arm portion 12 of different lengths is required, the zipper 122 can be moved relative to the zipper 121 to a position corresponding to the length of the arm portion 12, and the flexible fixing device 20 can be moved to the position for fixing, so as to increase the versatility of the radioactive contaminant protection glove 100.

[0047] Please refer again Figure 2In some embodiments, the flexible fixing device 20 includes a first fixing ring 23 and a second fixing ring 24. The first fixing ring 23 is sleeved outside the second fixing ring 24 and is fixedly connected to the second fixing ring 24. A cavity is formed between the first fixing ring 23 and the second fixing ring 24 to accommodate the arm 12. In this way, the arm 12 extends between the first fixing ring 23 and the second fixing ring 24, so that the flexible fixing device 20 can easily slide along the longitudinal direction of the arm 12, and when the locking device 30 is locked to drive the first open end 21 and the second open end 22 of the flexible fixing device 20 to move closer to or farther from each other, the arm 12 can be evenly tightened or opened.

[0048] like Figure 3 As shown, specifically, one of the first fixing ring 23 and the second fixing ring 24 has a snap-on protrusion 231, and the other has a snap-on groove 241 that matches the snap-on protrusion 231, so that the first fixing ring 23 and the second fixing ring 24 are snap-on. In this way, the installation and removal of the first fixing ring 23 and the second fixing ring 24 can be facilitated, and at the same time, when the radioactive contaminant protection glove 100 is fixed, the first fixing ring 23 and the second fixing ring 24 are prevented from slipping, causing the flexible fixing device 20 to fail to fix the radioactive contaminant protection glove 100. Specifically in the embodiment of the present application, the snap-on protrusion 231 is provided on the first fixing ring 23, and the snap-on groove 241 is provided on the second fixing ring 24. Preferably, the snap-on protrusion 231 is hemispherical, and the snap-on groove 241 is inverted hemispherical. In other embodiments, the snap-on protrusion 231 and the snap-on groove 241 can also be other shapes, which are not limited here.

[0049] Please refer again Figure 2 In some embodiments, the radioactive contaminant protection glove 100 further includes a limiter 25, which is disposed on the outside of the flexible fixing device 20 and is used to limit the glove body 10 when it is extended into the glove box. In this way, the limiter 25 can make the radioactive contaminant protection glove 100 fit and limit the entrance of the matching glove box. At the same time, when the length of the arm portion 12 is adjusted, the arm portion 12 can be rolled up and fixed on the limiter 25 to facilitate the recovery of the arm portion 12. Specifically, the limiter 25 includes a plurality of sub-limiters 251, and the plurality of sub-limiters 251 are radially arranged around the flexible fixing device 20. In an embodiment of the present application, the sub-limiters 251 include three.

[0050] In some embodiments, the radioactive contaminant protection glove 100 further includes a guide plate 26, which is convexly disposed on the side of the flexible fixing device 20 facing the palm portion 11. In this way, since the material of the arm portion 12 is soft, wrinkles are easily generated when the flexible fixing device 20 slides on the arm portion 12, and the guide plate 26 can guide to avoid wrinkles hindering the sliding of the flexible fixing device 20. Specifically, in some embodiments, the guide plate 26 includes a plurality of sub-guide plates 261, and the plurality of sub-guide plates 261 are radially arranged around the flexible fixing device 20. In the embodiment of the present application, the sub-guide plates 261 include five.

[0051] Further, the sub-guide plate 261 includes a first sub-guide plate 2611 and a second sub-guide plate 2612, one end of the first sub-guide plate 2611 is fixedly connected to the first fixing ring 23, one end of the second sub-guide plate 2612 is fixedly connected to the second fixing ring 24, and a guiding space is formed between the first sub-guide plate 2611 and the second sub-guide plate 2612 to guide the arm portion 12. In this way, the first sub-guide plate 2611 and the second sub-guide plate 2612 can guide the inner side and the outer side of the arm portion 12 respectively. Specifically in the embodiment of the present application, the first sub-guide plate 2611 and the second sub-guide plate 2612 are in the shape of a strip plate. In other embodiments, the first sub-guide plate 2611 and the second sub-guide plate 2612 can also be in the shape of a circular plate. In other embodiments, the first sub-guide plate 2611 and the second sub-guide plate 2612 can also be in other shapes that can guide the arm portion 12, which is not limited here.

[0052] See also Figure 1 and Figure 2 In some embodiments, the flexible fixing device 20 is further provided with a first connecting member 27 and a second connecting member 28 on the side facing the zipper 121 to tighten the first opening end 21 and the second opening end 22 of the flexible fixing device 20 .

[0053] Specifically, one end of the first connecting member 27 and one end of the second connecting member 28 are connected to the first open end 21 and the second open end 22 respectively, and the other end of the first connecting member 27 is detachably connected to the other end of the second connecting member 28. In this way, the first open end 21 and the second open end 22 can be tightened or loosened by connecting or separating the corresponding first connecting member 27 and the second connecting member 28. Specifically in the embodiments of the present application, both the first connecting member 27 and the second connecting member 28 are binding ropes. In other embodiments, one of the first connecting member 27 and the second connecting member 28 is a binding rope, and the other can be detachably connected to the binding rope. In other embodiments, the first connecting member 27 and the second connecting member 28 can also be other connecting members that can tighten the first open end 21 and the second open end 22.

[0054] Furthermore, sub-guide plates 261 are disposed on the first open end 21 and the second open end 22 , and the first connecting member 27 and the second connecting member 28 are disposed on the two sub-guide plates 261 , respectively.

[0055] Please refer again Figure 4 In some embodiments, the fitting member 32 has a plurality of fitting portions 321, which are arranged at intervals along the length direction of the fitting member 32, and the plurality of fitting portions 321 correspond to the plurality of locking positions one by one. In this way, the method of determining the plurality of locking positions by setting the plurality of fitting portions 321 is simple, and the operation of changing the locking position is convenient.

[0056] In some embodiments, the locking device 30 further includes a rotating member 33 and a rotating shaft 34. The rotating shaft 34 is installed at the first open end 21. One end of the rotating member 33 is connected to the locking member 31. The rotating member 33 can rotate around the rotating shaft 34 to drive the locking member 31 to switch between the unlocking position and the locking position. In this way, the locking member 31 can be more easily applied with the rotating member 33 so that the locking member 31 cooperates with the matching portion 321 to lock the flexible fixing device 20.

[0057] Furthermore, one end of the rotating member 33 is hinged to the locking member 31. In this way, the locking member 31 can be moved in the vertical direction to switch between the unlocking position and the locking position, thereby saving space and making the structure compact. In other embodiments, the rotating member 33 can also be fixedly connected to the locking member 31. In other embodiments, the rotating member 33 can also be connected to the locking member 31 by other connection methods, which are not limited here. Furthermore, the locking device 30 is provided with a slide groove 38, and the locking member 31 can slide in the slide groove 38.

[0058] In some embodiments, the locking device 30 further includes a first elastic member 35, one end of which is connected to an end of the rotating member 33 away from the locking member 31, and the other end of the first elastic member 35 is connected to the first open end 21. The first elastic member 35 can provide a pre-tightening force to keep the locking member 31 and the matching member 32 in engagement. In this way, the locking member 31 can be switched from an unlocked position and maintained in a locked position by the elastic force of the first elastic member 35, thereby ensuring that the locking device 30 reliably locks the flexible fixing device 20. Specifically, the first elastic member 35 includes two sub-first elastic members 351, which are relatively arranged on both sides of the locking device 30 along the axial direction of the arm portion 12. Specifically, in the embodiments of the present application, the first elastic member 35 is a spring. In other embodiments, the first elastic member 35 can also be a rubber member or other elastic member that can keep the locking member 31 and the matching member 32 in engagement, which is not limited here.

[0059] Furthermore, the locking device 30 also includes a pressing member 36, which is connected to an end of the first elastic member 35 away from the rotating member 33 and is movably connected to the first open end 21. In this way, the first elastic member 35 can be more easily exerted with force through the pressing member 36, thereby causing the locking member 31 to lock the mating portion 321. Specifically, the pressing member 36 includes two sub-pressing members 361, which are relatively arranged on both sides of the locking device 30 along the axial direction of the arm portion 12. In the embodiment of the present application, the pressing member 36 is in the shape of a square block. In other embodiments, the pressing member 36 may also be arranged at other positions of the locking device 30, and the pressing member 36 may also be in the shape of a round block or other shapes, which are not limited here.

[0060] In the embodiment of the present application, the locking member 31 includes two sub-locking members 311, and a locking channel is formed between the two sub-locking members 311 for the mating member 32 to extend into, and the two sub-locking members 311 can be moved closer to or farther from each other to switch between the unlocking position and the locking position. In this way, the mating portion 321 can be more reliably limited in the axial direction by the two sub-locking members 311, so that the locking device 30 can more reliably lock the flexible fixing device 20.

[0061] In the embodiment of the present application, the locking device 30 further comprises a locking device body 37, and the locking device body 37 has an inner cavity 371 for installing the locking member 31, the rotating member 33, the rotating shaft 34, the first elastic member 35 and the pressing member 36. In some other embodiments, the locking device 30 can also be directly disposed on the first opening end 21.

[0066] In some embodiments, the adjusting device 40 further includes a sliding member 43, the adjusting rod 42 is threadedly connected to the sliding member 43, and the sliding member 43 can slide relative to the adjusting rod 42 along the longitudinal direction of the adjusting rod 42 when the adjusting rod 42 rotates relative to the adjusting device body 41, and the traction member 50 is penetrated by the sliding member 43 to be fixedly connected to the adjusting rod 42. In this way, through the sliding of the sliding member 43, the traction member 50 can move the winding position while winding, so that the traction member 50 can be evenly wound on the adjusting rod 42, and the traction member 50 is prevented from being wound at the same position on the adjusting rod 42, resulting in a malfunction caused by squeezing and jamming between the traction member 50 and the adjusting device body 41.

[0067] Specifically, the sliding member 43 is a nut, so that it can be threadedly connected to the adjusting rod 42. Preferably, the sliding member 43 is a hexagonal nut, and the adjusting device body 41 is provided with a hexagonal hole. Through the cooperation of the hexagonal nut and the hexagonal hole, the axial rotation of the sliding member 43 can be limited, so that the sliding member 43 can slide relative to the adjusting rod 42 in the hexagonal hole.

[0068] Please refer again Figure 1 In some embodiments, the radioactive contaminant protection glove 100 further includes a mounting member 70, which is sleeved at the connection between the palm portion 11 and the arm portion 12, and the adjustment device 40 can be mounted on the mounting member 70. Specifically, the cross section of the mounting member 70 is waist-shaped.

[0069] The radioactive contaminant protection glove 100 provided in the embodiment of the present application has at least the following beneficial effects:

[0070] (1) A flexible fixing device with an opening is provided between the palm and the arm, and the first opening end and the second opening end are locked by a locking device, and the radial dimension of the flexible fixing device is adjusted so that the flexible fixing device can reliably fix the radioactive contaminant protective gloves on the palm and the arm of the worker, thereby preventing the radioactive contaminant protective gloves from loosening.

[0071] (2) The adjustment device can be used to adjust the tightness of the palm, making it easier for the operator to perform operating actions.

[0072] (3) The limiting member enables the radioactive pollutant protection gloves to fit into the matching glove box when extended into the glove box, thereby limiting the position of the radioactive pollutant protection gloves.

[0073] (4) The length of the arm can be adjusted by combining the zipper and the flexible fixing device to meet different needs and improve the versatility of the radioactive contaminant protection gloves.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
