Description

Technical Field

[0001] This invention relates to the field of protective clothing technology, specifically to multifunctional protective clothing for border defense. Background Technology

[0002] Border defense protective clothing is special protective equipment used by border troops to protect themselves from harmful substances such as toxic agents, biological warfare agents, and radioactive dust. In border areas, various potential chemical and biological threats may arise, such as toxic agent leaks and terrorist attacks using biological and chemical weapons. Protective clothing effectively protects border personnel, preventing harm from toxic agents absorbed through the skin or inhaled, thus ensuring their safety and health. It is typically made of high-strength nylon fabric coated with synthetic rubber on both sides, effectively isolating the body from the external environment. It is primarily used for protection against large amounts of skin-penetrating toxic agents and other harmful substances, and can defend against liquid and vaporized chemical and biological warfare agents, radioactive dust, and various other biochemical and hazardous substances.

[0003] For example, a painter's protective suit with publication number CN117065244A involves wearing the main body of the protective suit on the user's body, while simultaneously installing and wearing protective devices on the user's face to prevent toxic and harmful substances from entering the user's body. Fixing components are fixed to the user's shoulders, and the outer shell is fixed to the user's back through the fixing components. The first ventilation pipe and the second ventilation pipe are respectively connected to the first connection port and the second connection port, so that the internal area is connected to the storage cavity of the outer shell. When the power is turned on, the temperature control component starts to work, realizing the temperature regulation of the internal area of ​​the painter's protective suit.

[0004] To prevent excessively high temperatures inside the protective suit, this patent includes a cooling device installed on the back of the suit. This device draws in external airflow, filters it, cools it, and then introduces it into the suit, thus lowering the internal temperature. However, because no cleaning device is installed at the air inlet of the cooling device, lightweight floating objects such as leaves and plastic bags can adhere to the filter screen, affecting airflow. Furthermore, while cleaning the filter screen involves brushing it to remove dust, some dust particles are broken into smaller particles that can pass through the dust filter and enter the cooling device, affecting internal equipment. Simply brushing is insufficient to remove dust from the filter screen; some particles re-adhere during the floating process, making efficient cleaning of the filter screen difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-functional protective suit for border defense, in order to solve the problems mentioned in the background art.

[0017] Preferably, the endoscope cleaning mechanism includes a rotating rod rotatably connected to the top of the goggles via a bearing. A spiral groove is formed on the outer side of the rotating rod, and a protrusion is slidably connected to the inner side of the spiral groove. One side of the protrusion is hemispherical, and the other side is fixed to a moving block. One side of the moving block abuts against the goggles. A toggle block is fixedly connected to both ends of the moving block. A slanted rod abuts against the top of the toggle block. A cleaning brush b is welded to one end of the slanted rod.

[0019] Preferably, an abrasion-resistant pad is provided at the elbow joint of the sleeve of the protective clothing body. A cushioning pad is fixedly connected to one side of the abrasion-resistant pad. A slot is opened inside the cushioning pad, and a locking rod is inserted into the slot. One end of the locking rod is fixedly connected to the protective clothing body. A Velcro hook side is sewn and fixed to one side of the abrasion-resistant pad. A Velcro loop side is glued and fixed to one side of the Velcro loop side. A limit bag is sewn and fixed to one side of the limit bag. One side of the limit bag is sewn and fixed to the protective clothing body. The inner side of the limit bag is connected to the abrasion-resistant pad.

[0020] Specifically, the limiting bag can limit the bottom of the abrasion pad to prevent it from being lifted up and detached from the protective clothing body.

[0021] Preferably, one end of the lever is fixedly connected to a protrusion, and the buffer pad has a groove inside, which engages with the protrusion.

[0022] Compared with existing technologies, the advantages of this multi-functional protective suit for border defense are:

[0023] 1. This multi-functional protective suit for border defense, when cooling its interior, uses a motor to engage bevel gears a, b, and c. Bevel gear c then reverses the fan blades, drawing external airflow into the cooling box. The airflow is cooled by the cooler and then enters the suit body through the ductwork to further cool the interior. During this process, the brush bristles do not contact the filter. A switching mechanism allows bevel gear b to rotate the fan blades forward, bringing the brush bristles into contact with the filter and removing dust from one side. As the airflow from the cooling box is expelled, the dust removed from the filter is carried away by the airflow, preventing it from returning to the cooling box. This process ensures smooth airflow into the cooling box, effectively dissipating heat from the interior of the protective suit.

[0024] 2. This multi-functional protective clothing for border defense, when debris adheres to the outside of the goggles and obstructs the soldier's vision, prevents the lenses from being effectively cleaned due to debris on the soldier's gloves. By moving the rack lever upwards, the rack lever engages with two sets of gear bodies b, thereby driving the two sets of gear bodies b and the corresponding cleaning brush a to rotate. When the cleaning brush a rotates, it contacts the lens through a cleaning strip on one side, thus scraping off the debris on the lens. This allows for cleaning of the lens without using gloves, ensuring the effectiveness of lens cleaning. When the rack lever is released, the tension spring a pulls the cleaning brush a back to its original position. Through the above operation, the goggles can be kept clean.

[0025] 3. When wearing this multi-functional protective clothing, to protect the easily worn joints of the sleeves, the limiting groove of the cushioning pad on one side of the abrasion-resistant pad is connected to the locking rod. When the protrusion at one end of the locking rod contacts the groove inside the cushioning pad, the protrusion engages with the cushioning pad. At this time, the bottom of the cushioning pad is fitted into the limiting bag, and the Velcro surface inside the limiting bag adheres to the Velcro hook surface on the abrasion-resistant pad. Therefore, when the abrasion-resistant pad is pulled at the edge, it will not detach from one side of the protective clothing body, thus achieving stable fixation of the abrasion-resistant pad. The abrasion-resistant pad can protect the joints of the sleeves, thereby reducing wear at the sleeve joints and extending the service life of the protective clothing body. In this way, the joints of the protective clothing can be easily protected. Attached Figure Description

Detailed Implementation

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Please see Figure 1-Figure 5 This invention provides a technical solution: a multi-functional protective suit for border defense, comprising: a protective suit body 1 and a cooling box 4, a gas mask 2 installed on the top of the protective suit body 1, and goggles 3 connected to the top of the gas mask 2.

[0039] A cold air box 4 is connected to one side of the protective clothing body 1 via a shoulder strap. An air inlet 5 is connected to the bottom of the cold air box 4. A cooler 6 is installed on one side of the cold air box 4. A bracket 24 is fixedly connected to the bottom of the air inlet 5. A filter screen 25 is fixedly connected to the outside of the bracket 24. A cleaning mechanism is provided at the bottom of the filter screen 25. The outside of the filter screen 25 is fixedly connected to the inside of the air inlet 5. A fan blade 8 is provided at the bottom of the cold air box 4. A drive mechanism is provided at the top of the fan blade 8. A connecting seat 7 is fixedly connected to the inside of the fan blade 8. The outside of the connecting seat 7 is movably connected to the cold air box 4 via a bearing. Two sets of air ducts 51 are fixedly connected to the top of the cold air box 4. One end of the air duct 51 is connected to the protective clothing body 1. Multiple filter elements 26 are provided at the top of the filter screen 25. The outside of the multiple filter elements 26 is fixedly connected to the air inlet 5. A switching mechanism is provided at the top of the connecting seat 7.

[0040] The drive mechanism includes a motor 9 mounted on top of the fan blade 8. A mounting bracket is fixed to the bottom of the motor 9, and both ends of the mounting bracket are welded to the inner side of the cold air box 4. A bevel gear a10 is fixedly connected to the output end of the motor 9. Bevel gears b11 and c12 are meshed on the outer side of bevel gear a10. One side of each bevel gear b11 and c12 is rotatably connected to the cold air box 4 via bearings. Bevel gears a10, b11, and c12 constitute a meshing transmission structure. The switching mechanism includes... An electric push rod 13 is fixedly connected to the inside of the cold air box 4. A locking block a14 is fixedly connected to the bottom of the electric push rod 13. A connecting block 15 is fixedly connected to the bottom of the locking block a14. A locking block b16 is welded and fixed to the bottom of the connecting block 15. A connecting rod 17 is welded and fixed to the bottom of the locking block b16. A rectangular rod 18 is fixedly connected to the bottom of the connecting rod 17. The outer side of the rectangular rod 18 is slidably connected to the connecting seat 7. A round rod 19 is welded and fixed to the bottom of the rectangular rod 18. The outer side of the round rod 19 is slidably connected to multiple sets of filter elements 26. The bottom of the round rod 19 is slidably connected to the bracket 24. The interior of the connecting seat 7 has a rectangular groove that matches the rectangular rod 18. The outer sides of the locking block b16 and the connecting rod 17 are slidably connected to the bevel gear c12. The output end of the electric push rod 13 is connected through to the bevel gear b11. The cross-sections of the locking blocks a14 and b16 are both hexagonal. The interiors of the bevel gears b11 and c12 have hexagonal grooves that match the locking blocks a14 and b16. The rectangular rod 18 and the connecting seat 7 form a sliding joint. The cleaning mechanism includes a connecting plate 20 fixedly connected to the bottom of the round rod 19. The top of the connecting plate 20 is movably connected to multiple sets of gear bodies a21 via a rotating shaft, and the multiple sets of gear bodies a21 mesh with each other. Each set of gear bodies a21 is fixedly connected to one side with bristles 22. The bristles 22 are made of nylon synthetic fiber. When the bristles come into contact with the filter screen 25, they will remove the dust adhering to its surface. A gear ring 23 is welded and fixed to the bottom of the air inlet 5. The multiple sets of gear bodies a21 form a meshing transmission structure.

[0041] In practical implementation, when the multi-functional protective suit for border defense is cooling its interior, the motor 9 drives the bevel gear a10 to rotate. Bevel gear a10 meshes with bevel gears b11 and c12, causing them to rotate synchronously in opposite directions. At this time, the locking block b16 is engaged with bevel gear c12, while the locking block a14 disengages from bevel gear b11. Therefore, locking block a14, connecting block 15, locking block b16, connecting rod 17, and rectangular rod 18 rotate with bevel gear c12. The rectangular rod 18 then drives the connecting seat 7 and the outer fan blades 8 to rotate in reverse, thereby introducing external airflow into the cold air box 4 for filtration. Core 26 filters and purifies the incoming airflow, while filter screen 25 blocks external dust. The airflow is cooled after passing through cooler 6 and then enters the protective clothing body 1 through air duct 51 to cool the interior. When the locking block b16 engages with bevel gear c12, the bristles 22 on the top of gear body a21 will disengage from filter screen 25, thus not cleaning filter screen 25. The rectangular rod 18 drives the connecting plate 20 to rotate through round rod 19, thereby blocking floating objects that approach filter screen 25 from the outside, preventing floating objects from blocking filter screen 25 and ensuring smooth air intake of cold air box 4.

[0042] When it is necessary to clean the dust on the filter screen 25, the electric push rod 13 is activated to move the locking block a14 upward, causing it to enter the hexagonal groove of the bevel gear b11 and engage with it. The locking block b16 then disengages from the bevel gear c12, causing the rectangular rod 18 to rotate with the bevel gear b11, thus driving the fan blade 8 to rotate clockwise. When the fan blade 8 rotates clockwise, it sends the airflow from the cold air box 4 to the outside. As the rectangular rod 18 moves upward, it drives the connecting plate 20 upward via the round rod 19, causing multiple sets of gear bodies a21 and brush bristles 22 to move upward. The brush bristles 22 then come into contact with the filter screen 25, and the outermost gear body a21 will... Engaging with the gear ring 23, the multiple sets of gear bodies a21 also rotate when the connecting plate 20 rotates, thereby driving the multiple sets of brush bristles 22 to rotate. Since the brush bristles 22 rotate with the connecting plate 20 while rotating on their own, they will have more frequent and more diverse contact with the filter screen 25, thus cleaning the filter screen 25 thoroughly and removing dust from one side. As the airflow in the cold air box 4 is discharged outward at this time, the dust cleaned off the filter screen 25 will also be carried away by the airflow, preventing the cleaned dust from drifting back into the cold air box 4. Through the above operation, the smooth airflow of the cold air box 4 can be ensured, thereby dissipating heat from the inside of the protective clothing.

[0043] Please see Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9A lens 27 is fixedly connected to one side of the goggles 3. An external lens cleaning mechanism is provided on one side of the lens 27, and an internal lens cleaning mechanism is provided on the other side of the lens 27. The external lens cleaning mechanism includes a limiting sleeve 29 fixedly connected to one side of the goggles 3. A rack rod 28 is slidably connected inside the limiting sleeve 29. Gear bodies b30 are meshed on both sides of the rack rod 28. One side of the gear body b30 is rotatably connected to the goggles 3 via a rotating shaft. A cleaning brush a31 is welded and fixed to the outside of the gear body b30. One side of the cleaning brush a31... A tension spring a32 is fixedly connected, with one end of the tension spring a32 fixed to the limiting sleeve 29. A rack rod 28 and a gear body b30 form a meshing transmission structure. The gear body b30 and the goggles 3 form a rotating structure via a rotating shaft. A through groove is provided inside the limiting sleeve 29, and the limiting sleeve 29 and the rack rod 28 form a sliding structure. The endoscope cleaning mechanism includes a rotating rod 33 rotatably connected to the top of the goggles 3 via a bearing. A spiral groove 34 is provided on the outer side of the rotating rod 33, and a protrusion 35 is slidably connected to the inner side of the spiral groove 34. One side is hemispherical, and the other side of the protrusion 35 is fixed to the movable block 36. One side of the movable block 36 abuts against the goggles 3. Both ends of the movable block 36 are fixedly connected to the actuating blocks 37. The top of the actuating block 37 abuts against the inclined rod 38. A cleaning brush b39 is welded and fixed to one end of the inclined rod 38. One end of the cleaning brush b39 is rotatably connected to the goggles 3 via a rotating shaft. A tension spring b40 is fixedly connected to one side of the cleaning brush b39. One end of the tension spring b40 is fixed to the goggles 3. A cleaning brush c4 is slidably connected inside the cleaning brush b39. 2. One end of the cleaning brush c42 abuts against a spring 41, and one end of the spring 41 abuts against the inner side of the cleaning brush b39. Both sides of the cleaning brush b39 are fixedly connected to sliders 43, and the outer side of the sliders 43 is slidably connected to the cleaning brush b39. Cleaning strips are fixedly connected to one side of the cleaning brush a31, the cleaning brush b39 and the cleaning brush c42. The inside of the cleaning brush b39 is provided with a groove that matches the slider 43. The slider 43 and the cleaning brush b39 form a sliding connection. The cleaning brush b39 forms a rotating structure with the goggles 3 through a rotating shaft.

[0044] In practical implementation, when debris adheres to the outside of the goggles 3 of this border defense multi-functional protective clothing, affecting the soldier's vision, in order to prevent debris on the soldier's gloves from preventing effective cleaning of the lens 27, the rack rod 28 is moved upward. When the rack rod 28 moves, it will mesh with two sets of gear bodies b30, thereby driving the two sets of gear bodies b30 and the corresponding cleaning brush a31 to rotate. When the cleaning brush a31 rotates, it will contact the lens 27 through the cleaning rubber strip on one side, thereby scraping off the debris on the lens 27. In this way, the lens 27 can be cleaned without using gloves, ensuring the cleaning effect of the lens 27. When the rack rod 28 is released, the tension spring a32 will pull the cleaning brush a31 to reset.

[0045] When a soldier's exhaled breath comes into contact with the lens 27, fogging occurs due to the temperature difference between the inside and outside of the lens 27, affecting the soldier's vision. To facilitate the removal of fog from the lens 27, the rotating rod 33 is rotated. Since one end of the protrusion 35 contacts the spiral groove 34 on the outside of the rotating rod 33, the protrusion 35 moves upward when the rotating rod 33 rotates. The protrusion 35 then moves the moving block 36 upward as well. Because one side of the moving block 36 abuts against the goggles 3, the moving block 36 does not rotate. When the toggle blocks 37 on both sides of the movable block 36 move upward, they will cause the two sets of inclined rods 38 to rotate, which will also cause the cleaning brush b39 at one end of the inclined rod 38 to rotate. The cleaning brush b39 will pull the tension spring b40 to extend. When the cleaning brush b39 rotates, it will contact the inside of the lens 27 through the cleaning strip on one side, thereby removing the fog on the inside of the lens 27 and keeping the lens 27 clear. When the rotating rod 33 is released, the tension spring b40 will pull the rotating rod 33 to return to its original position. In this way, the goggles 3 can be kept clean.

[0046] Please see Figure 1 and Figure 10 The protective clothing body 1 has an abrasion-resistant pad 46 at the elbow joint of the sleeve. A cushioning pad 45 is fixedly connected to one side of the abrasion-resistant pad 46. The cushioning pad 45 has a slot inside, and a locking rod 44 is inserted into the slot. One end of the locking rod 44 is fixedly connected to the protective clothing body 1. A Velcro hook surface 47 is sewn and fixed to one side of the abrasion-resistant pad 46. A Velcro loop surface 48 is glued and fixed to one side of the Velcro hook surface 47. A limit pocket 49 is sewn and fixed to one side of the Velcro loop surface 48. One side of the limit pocket 49 is sewn and fixed to the protective clothing body 1. The inside of the limit pocket 49 is connected to the abrasion-resistant pad 46. A protrusion 50 is fixedly connected to one end of the locking rod 44. A groove is opened inside the cushioning pad 45, and the groove engages with the protrusion 50. The protrusion 50 and the cushioning pad 45 form an engaging mechanism.

[0047] In practical implementation, when wearing this multi-functional protective clothing, to protect the easily worn joints of the sleeves, the limiting groove of the cushioning pad 45 on one side of the abrasion-resistant pad 46 is connected to the locking rod 44. When the protrusion 50 at one end of the locking rod 44 contacts the groove inside the cushioning pad 45, the protrusion 50 will engage with the cushioning pad 45. At this time, the bottom of the cushioning pad 45 will be fitted into the limiting bag 49, and the Velcro surface 48 on the inside of the limiting bag 49 will be bonded to the Velcro hook surface 47 on one side of the abrasion-resistant pad 46. Therefore, when the abrasion-resistant pad 46 is pulled at the edge, it will not detach from one side of the protective clothing body 1, thus completing the stable fixation of the abrasion-resistant pad 46. The abrasion-resistant pad 46 can protect the joints of the sleeves, thereby reducing wear at the joints and extending the service life of the protective clothing body 1. In this way, the joints of the protective clothing can be easily protected through the above operation.

[0048] In summary: When using the multi-functional protective suit for border defense, the border guards first put on the suit body 1 to isolate themselves from the outside world and protect against liquid and vapor chemical warfare agents, biological warfare agents, radioactive dust, and various biochemical and harmful substances. The gas mask 2 can filter and purify the external gases, and the goggles 3 can prevent toxic gases from damaging the eyes. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.

[0049] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
