Description

Technical Field

[0001] This invention relates to the field of protective clothing technology, specifically vests. Background Technology

[0002] Tactical vests are mainly composed of fabric, equipment pockets, buckles, and stitching. The primary considerations for fabric selection are: non-flammable, durable, and waterproof. Early vests were mostly made of materials such as leather and canvas, which increased in weight due to water absorption. Later, nylon was chosen as the fabric for vests, reducing weight and increasing durability.

[0003] A Chinese patent, publication number CN113606994A, discloses a tactical vest, including a front panel and a rear panel. The front panel has an adjustment portion on at least one side along the width direction of the vest, and the adjustment portion has at least two locking positions spaced apart along the width direction of the vest. The rear panel has a first buckle on at least one side along the width direction of the vest, and the first buckle can engage with any locking position on the corresponding side. This tactical vest offers convenient size adjustment and is not easily loosened.

[0004] However, the tactical vests currently on the market do not provide buoyancy for users when wading. In addition, the vests are equipped with a lot of gear, making them heavy. When wading, users need to carry a lot of weight, which is quite strenuous and can easily lead to drowning. Summary of the Invention

[0005] The purpose of this invention is to provide a vest to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vest, comprising:

[0007] The rear protective plate has a front protective plate on one side. The top of the rear protective plate and the front protective plate are connected by a shoulder strap. Elastic bands are fixed on both sides of the front and rear protective plates. The two elastic bands can be connected to each other by Velcro.

[0008] A buoyancy mechanism is located between the front and rear protective plates and is connected to the front protective plate. The buoyancy mechanism can provide buoyancy to the user when the user needs to wade through water, making it easier for the user to wade through water.

[0009] Several storage bags are fixed to the side of the front protective plate away from the rear protective plate for easy loading of equipment. One of the storage bags contains an inflation mechanism that can inflate the buoyancy mechanism.

[0010] Preferably, the buoyancy mechanism includes a first baffle and a second baffle. The second baffle is fixedly connected to the front protective plate. A rubber ring is provided between the first baffle and the second baffle. Both the first baffle and the second baffle are fixedly connected to the rubber ring. The rubber ring, the first baffle, and the second baffle form a sealed space. An air inlet pipe passes through the rubber ring. Air is pumped into the rubber ring through the air inlet pipe, causing the rubber ring to expand, thereby providing buoyancy support for the user.

[0011] Preferably, both sides of the first and second baffles are connected by zippers, and soft fabric is fixed to both sides of the first and second baffles. The main chain and the secondary chain of the zipper are fixed to the two pieces of soft fabric respectively. The first and second baffles can be connected and separated by the zipper. Normally, the zipper is in a closed state. When the rubber ring is needed, the zipper is opened. The fact that both sides of the first and second baffles have zippers makes it convenient for the user to open the zipper with both hands at the same time. Several protrusions are fixed to the side of the first baffle away from the second baffle. When the user wears the vest, the protrusions can reduce the contact area between the first baffle and the user, enhance the heat dissipation effect, and improve the comfort of the staff.

[0012] Preferably, the second baffle is provided with a ventilation mechanism, which includes a plurality of air guide tubes fixed to the side of the second baffle facing the first baffle. Each of the plurality of air guide tubes has a plurality of round holes. The plurality of air guide tubes are connected by a connecting pipe. One of the plurality of air guide tubes is connected to an air inlet pipe. Gas enters the air guide tube from the air inlet pipe and then enters the interior of the rubber ring from the round holes. The connection between the air inlet pipe and the plurality of air guide tubes allows the gas to enter the interior of the rubber ring evenly, causing the rubber ring to expand evenly and improving the user's comfort.

[0013] Preferably, a plurality of cylinders are fixed to the side of the baffle facing the second baffle, and the plurality of cylinders correspond one-to-one with a plurality of circular holes. The cylinders and circular holes are matched. When the rubber ring is not used, the cylinders on the first baffle are inserted into the circular holes on the air duct, and then the zipper is pulled up. The matching of the cylinders and circular holes can prevent the first baffle and the second baffle from moving up and down when the user runs. Up and down misalignment will cause wear and tear on the inside of the first baffle and the second baffle and the rubber ring. At the same time, the fact that the first baffle and the second baffle do not move up and down can also improve the user's wearing comfort.

[0014] Preferably, a limiting mechanism is provided between both sides of the rear protective plate and the front protective plate;

[0015] The limiting mechanism includes a fixed plate and an insert plate. The fixed plate is fixedly connected to the elastic band on the front protective plate, and the insert plate is fixedly connected to the elastic band on the rear protective plate. The fixed plate has a slot on the side facing the insert plate, which matches the insert block. Sliding blocks are fixed on both sides of the insert plate. Sliding grooves are formed on both sides of the inner wall of the slot, and the sliding blocks match the sliding grooves. The insert plate can drive the sliding blocks to slide within the sliding grooves. The distance the sliding blocks can slide within the sliding grooves is the same as the distance between baffle one and baffle two after the rubber ring is inflated. A fixed block is fixed to the bottom of the fixed plate on the side away from the front protective plate. A sliding groove is formed inside the fixed block, and a sliding plate is provided inside the sliding groove. A sealing ring is provided between the sliding plate and the sliding groove. The sliding plate is connected to a limiting post via a rotating part. A movable plate is fixed on the limiting post. A rectangular plate is fixed to the inner wall of the sliding groove, and the limiting post penetrates the rectangular plate. A spring is sleeved on the limiting post, located between the movable plate and the rectangular plate. A limiting hole is formed at the bottom of the insert plate, a notch is formed at the bottom of the fixed plate, and a notch is formed at the top of the fixed block. The device has a guide hole, through which the limiting post can pass and enter the limiting hole. The bottom of the fixing block is connected to the rubber ring via a hose. Gas enters the slide groove from inside the rubber ring through the hose, pushing the slide plate to slide within the groove. The slide plate moves upward, causing the rotating part to rotate. The rotating part causes the limiting post to move downward, which in turn causes the moving plate to press down on the first spring. At this time, the limiting post moves out of the limiting hole, allowing the insert plate to move within the slot. This facilitates adjustment of the distance between the front and rear protective plates, preventing the user from being squeezed by the first baffle and the rear protective plate due to the unchanged distance between the front and rear protective plates after the rubber ring expands. This improves user comfort. When the gas is discharged, the slide plate lacks gas pressure. At this time, the insert plate is moved to the innermost part of the slot, aligning the limiting post with the limiting groove. Since the first spring is in a compressed state, the moving plate will drive the limiting post into the limiting groove under the action of the first spring, thus limiting the insert plate and restoring the distance between the front and rear protective plates to the distance when the rubber ring is not inflated.

[0016] Preferably, the rotating part includes a rotating block, which is rotatably connected to the inner wall of the slide groove. Each end of the rotating block has a movable groove, and a movable block slides within each of the two movable grooves. A connecting block is fixed to each of the two movable blocks, and the two connecting blocks are rotatably connected to a limiting post and a sliding plate, respectively. Rectangular blocks are fixed to both sides of each of the two movable blocks. Rectangular grooves are formed on both sides of the inner wall of each of the two movable grooves, and the rectangular blocks match the rectangular grooves. When the rotating block rotates, the limiting post and the sliding plate drive the movable block to move within the movable groove through the connecting blocks. Simultaneously, the movable block drives the rectangular blocks to move within the rectangular groove, thus limiting the movement distance of the movable block.

[0017] Preferably, the inflation mechanism includes a housing with an outlet pipe connected to one side. A filter plate is fixed inside the housing to prevent chemical leakage from the outlet pipe. Two circular plates are also included, with the first circular plate located between the second circular plate and the filter plate. Two copper plates pass through the first circular plate, and a resistance wire is fixed between them. The resistance wire is located between the filter plate and the first circular plate. A battery is fixed to the first circular plate and connected to the two copper plates via wires. A copper pillar passes through the second circular plate, and a connecting plate is fixed to the side of the pillar away from the second circular plate. A second spring is fitted onto the copper pillar, which is always compressed to provide support for the moving plate and prevent leakage. The column contacts the copper sheet. The second spring is located between the second circular plate and the connecting plate. A push block is fixed on the side of the connecting plate away from the copper column. The push block penetrates the outer shell. When the push block is pressed, it will drive the copper column to move through the connecting plate. At the same time, the connecting plate will squeeze the second spring. When the copper column moves to contact the two copper sheets, the battery will supply power to the resistance wire. The resistance wire will generate heat. The outer shell contains a chemical substance between the filter plate and the first circular plate. The chemical substance can be ammonium nitrate. When heated, ammonium nitrate will undergo a chemical reaction and rapidly produce a large amount of ammonia gas. The chemical reaction equation is: NH4NO3=HNO3+NH3↑. The ammonia gas will pass through the filter plate and be discharged from the outlet pipe.

[0018] Preferably, the air outlet pipe can be threadedly connected to the air inlet pipe, which facilitates the connection between the inflation mechanism and the air inlet pipe, allowing gas to enter the interior of the rubber ring. A protective cover is threadedly connected to the end of the outer shell near the push block to prevent accidental contact with the push block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting up an inflation mechanism, the buoyancy mechanism can be quickly inflated, so that the buoyancy mechanism provides buoyancy to the user, making it easier for the user to wade in water and improving the user's safety when wading in water.

[0021] 2. By setting a limiting mechanism, the distance between the front and rear protective plates can be automatically adjusted while the buoyancy mechanism is being inflated, eliminating the need for manual adjustment. This improves user comfort and adjustment efficiency.

[0022] 3. By setting up a ventilation mechanism, gas can be evenly introduced into the buoyancy mechanism, improving user comfort. At the same time, when the ventilation mechanism is not ventilating, it can also limit the movement of baffle one and baffle two, preventing them from shifting up and down when the user is running, thus improving the user's wearing comfort.

[0035] 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.

[0036] Please see Figures 1 to 11 One embodiment of the present invention provides a vest, comprising:

[0037] The rear protective plate 1 has a front protective plate 3 on one side. The top of the rear protective plate 1 and the front protective plate 3 are connected by a shoulder strap 2. Both sides of the front protective plate 3 and the rear protective plate 1 are fixed with elastic bands 7. The two elastic bands 7 can be connected to each other by Velcro.

[0038] The buoyancy mechanism 8 is located between the front protective plate 3 and the rear protective plate 1. The buoyancy mechanism 8 is connected to the front protective plate 3. The buoyancy mechanism 8 can provide buoyancy to the user when the user needs to wade through water, making it easier for the user to wade through water.

[0039] Several storage bags 5 are fixed to the side of the front protective plate 3 away from the rear protective plate 1 for easy loading of equipment. One of the storage bags 5 contains an inflation mechanism 4, which can inflate the buoyancy mechanism 8.

[0040] The buoyancy mechanism 8 includes a first baffle 801 and a second baffle 804. The second baffle 804 is fixedly connected to the front protective plate 3. A rubber ring 803 is provided between the first baffle 801 and the second baffle 804. Both the first baffle 801 and the second baffle 804 are fixedly connected to the rubber ring 803. The rubber ring 803, the first baffle 801 and the second baffle 804 form a sealed space. An air inlet pipe 806 passes through the rubber ring 803. Air is pumped into the rubber ring 803 through the air inlet pipe 806, and the rubber ring 803 will expand, thereby providing buoyancy support for the user.

[0041] In addition, both sides of the first baffle 801 and the second baffle 804 are connected by zippers 805. Soft fabric is fixed to both sides of the first baffle 801 and the second baffle 804. The main chain and the secondary chain of the zipper 805 are fixed to the two soft fabrics respectively. The zipper 805 can connect and separate the first baffle 801 and the second baffle 804. Normally, the zipper 805 is in the closed state. When the rubber ring 803 is needed, the zipper 805 is pulled open. The fact that both sides of the first baffle 801 and the second baffle 804 have zippers 805 makes it convenient for the user to pull the zipper 805 with both hands at the same time. Several protrusions 802 are fixed on the side of the first baffle 801 away from the second baffle 804. When the user wears the vest, the protrusions 802 can reduce the contact area between the first baffle 801 and the user, enhance the heat dissipation effect, and improve the comfort of the staff.

[0042] Meanwhile, the second baffle 804 is equipped with a ventilation mechanism 9, which includes several air guide pipes 902 fixed on the side of the second baffle 804 facing the first baffle 801. Each of the air guide pipes 902 has several round holes 901. The air guide pipes 902 are connected through connecting pipes 903. One of the air guide pipes 902 is connected to the air inlet pipe 806. Gas will enter the air guide pipe 902 from the air inlet pipe 806, and then enter the rubber ring 803 from the round holes 901. The connection between the air inlet pipe 806 and the air guide pipes 902 allows the gas to enter the rubber ring 803 evenly, so that the rubber ring 803 expands evenly and improves the user's comfort.

[0043] It is worth noting that several cylinders 904 are fixed on the side of the first baffle 801 facing the second baffle 804. The cylinders 904 correspond one-to-one with several holes 901. The cylinders 904 and the holes 901 are matched. When the rubber ring 803 is not in use, the cylinders 904 on the first baffle 801 are inserted into the holes 901 on the air duct 902, and then the zipper 805 is pulled up. The cooperation of the cylinders 904 and the holes 901 can prevent the first baffle 801 and the second baffle 804 from moving up and down when the user runs. Up and down movement will cause wear and tear on the inside of the first baffle 801 and the second baffle 804 and the rubber ring 803. At the same time, the fact that the first baffle 801 and the second baffle 804 do not move up and down can also improve the user's wearing comfort.

[0044] Furthermore, a limiting mechanism 6 is provided between both sides of the rear protective plate 1 and the front protective plate 3;

[0045] The limiting mechanism 6 includes a fixed plate 604 and an insert plate 601. The fixed plate 604 is fixedly connected to the elastic band 7 on the front protective plate 3, and the insert plate 601 is fixedly connected to the elastic band 7 on the rear protective plate 1. The fixed plate 604 has a slot 608 on the side facing the insert plate 601, and the slot 608 matches the insert block. Sliding blocks 607 are fixed on both sides of the insert plate 601. Sliding grooves 609 are formed on both sides of the inner wall of the slot 608, and the sliding blocks 607 match the sliding grooves 609. The insert plate 601 can drive the sliding blocks 607 to slide in the sliding grooves 609. The distance that the sliding blocks 607 can slide in the sliding grooves 609 is the same as the distance between the first baffle 801 and the second baffle 804 after the rubber ring 803 is inflated. A fixing block 602 is fixed to the bottom of the fixed plate 604 on the side away from the front protective plate 3. A groove 616 is formed inside the fixing block 602, and a sliding plate 617 is provided inside the groove 616. A sealing ring is provided between the sliding plate 617 and the groove 616. The sliding plate 617 is connected to a limiting post 606 via a rotating part 615. A movable plate 612 is fixed on the limiting post 606. A rectangular plate 614 is fixed to the inner wall of the groove 616, and the limiting post 606 passes through the rectangular plate 614. A spring 613 is sleeved on the limiting post 606, located between the movable plate 612 and the rectangular plate 614. A limiting hole 605 is formed at the bottom of the insert plate 601, and a notch 610 is formed at the bottom of the fixing plate 604. A notch 610 is formed at the top of the fixing block 602. A guide hole 611 is provided, through which the limiting post 606 can pass and the notch 610 and enter the limiting hole 605. The bottom of the fixing block 602 is connected to the rubber ring 803 via a hose 603. After gas enters the slide groove 616 from inside the rubber ring 803 through the hose 603, the gas will push the slide plate 617 to slide in the slide groove 616. The slide plate 617 will move upward, driving the rotating part 615 to rotate. The rotating part 615 will drive the limiting post 606 to move downward. The limiting post 606 will drive the moving plate 612 to press the spring 613 downward. At this time, the limiting post 606 will move out of the limiting hole 605, and the insert plate 601 can then move in the slot 608 for easy adjustment. The distance between the front protective plate 3 and the rear protective plate 1 is designed to prevent the user from being squeezed by the baffle 801 and the rear protective plate 1 due to the unchanged distance between the front protective plate 3 and the rear protective plate 1 after the rubber ring 803 expands, thus improving the user's comfort. When the gas is discharged, the slide plate 617 lacks gas pressure. At this time, the insert plate 601 is moved to the innermost part of the slot 608. At this time, the limiting post 606 is aligned with the limiting groove. Since the spring 613 is in a compressed state, the moving plate 612 will drive the limiting post 606 into the limiting groove under the action of the spring 613, thereby limiting the insert plate 601 and restoring the distance between the front protective plate 3 and the rear protective plate 1 to the distance when the rubber ring 803 is not inflated.

[0046] In addition, the rotating part 615 includes a rotating block 6156, which is rotatably connected to the inner wall of the slide groove 616. Both ends of the rotating block 6156 are provided with moving grooves 6155, and moving blocks 6154 slide within each of the two moving grooves 6155. Connecting blocks 6153 are fixed to each of the two moving blocks 6154, and the two connecting blocks 6153 are rotatably connected to the limiting post 606 and the sliding plate 617, respectively. Rectangular blocks 615 are fixed to both sides of each of the two moving blocks 6154. 1. Rectangular grooves 6152 are provided on both sides of the inner wall of the two moving grooves 6155. The rectangular block 6151 matches the rectangular groove 6152. When the rotating block 6156 rotates, the limiting post 606 and the sliding plate 617 will drive the moving block 6154 to move in the moving groove 6155 through the connecting block 6153. At the same time, the moving block 6154 will drive the rectangular block 6151 to move in the rectangular groove 6152, thus limiting the moving distance of the moving block 6154.

[0047] It is worth noting that the storage bag 5 contains an inflation mechanism 4, which is disposable and needs to be replaced after use. The inflation mechanism 4 includes a housing 401, with an air outlet pipe 403 connected to one side of the housing 401. A filter plate 413 is fixed inside the housing 401 to prevent chemical substances from leaking from the air outlet pipe 403. A first circular plate 405 and a second circular plate 411 are also included. The first circular plate 405 is located between the second circular plate 411 and the filter plate 413. The first circular plate 405 has a central... Two copper plates 406 are threaded through the filter plate 413 and a resistance wire 404 is fixed between them. The resistance wire 404 is located between the filter plate 413 and the first circular plate 405. A battery 412 is fixed on the first circular plate 405 and is connected to the two copper plates 406 via wires. A copper column 407 passes through the second circular plate 411. A connecting plate 409 is fixed to the side of the copper column 407 away from the second circular plate 411. A second spring 410 is fitted on the copper column 407. The second spring 410 is always in a constant state. In the compressed state, it provides support for the moving plate 612, preventing the copper pillar 407 from contacting the copper sheet 406. The second spring 410 is located between the second circular plate 411 and the connecting plate 409. A push block 408 is fixed on the side of the connecting plate 409 away from the copper pillar 407. The push block 408 passes through the outer shell 401. When the push block 408 is pressed, it will drive the copper pillar 407 to move through the connecting plate 409. At the same time, the connecting plate 409 will squeeze the second spring 410. When the copper pillar 407 moves to contact the two copper sheets 406, the battery 412 will supply power to the resistance wire 404. The resistance wire 404 will generate heat. The outer shell 401 contains a chemical substance between the filter plate 413 and the first circular plate 405. The chemical substance can be ammonium nitrate. When heated, ammonium nitrate will undergo a chemical reaction and rapidly produce a large amount of ammonia gas. The chemical reaction equation is: NH4NO3=HNO3+NH3↑. The ammonia gas will pass through the filter plate 413 and be discharged from the outlet pipe 403.

[0048] Furthermore, the air outlet pipe 403 can be threadedly connected to the air inlet pipe 806, which facilitates the connection between the inflation mechanism 4 and the air inlet pipe 806, allowing gas to enter the interior of the rubber ring 803. A protective cover 402 is threadedly connected to the end of the outer shell 401 near the push block 408 to prevent accidental contact with the push block 408.

[0049] When wading is required, first unzip the zippers 805 on both sides, then remove the inflation mechanism 4 from the storage bag, install the air outlet pipe 403 on the inflation mechanism 4 into the air inlet pipe 806, then remove the protective cover 402 on the inflation mechanism 4, press the actuating block 408, the actuating block 408 will drive the copper column 407 to move through the connecting plate 409, and at the same time the connecting plate 409 will squeeze the second spring 410. When the copper column 407 moves to contact the two copper plates 406, the battery 412 will supply power to the resistance wire 404, the resistance wire 404 will generate heat, and the ammonium nitrate will undergo a chemical reaction after heating to produce a large amount of ammonia gas. The ammonia gas will pass through the filter plate 413 and enter the air guide pipe 902 through the air outlet pipe 403, and then enter the rubber ring 803 through the round hole 901. The air inlet pipe 806 is connected to several air guide pipes 902 to allow the air to pass through. Gas enters the rubber ring 803 evenly, causing it to expand uniformly and improving user comfort. Simultaneously, ammonia gas enters the fixed block 602 through the hose 603, pushing the slide plate 617 upwards. The slide plate 617 moves upwards, driving the rotating part 615 to rotate. The rotating part 615 then moves the limiting post 606 downwards, causing the moving plate 612 to press down on the spring 613. At this point, the limiting post 606 moves out of the limiting hole 605, allowing the insert plate 601 to move within the slot 608. This facilitates adjustment of the distance between the front protective plate 3 and the rear protective plate 1, preventing the user from being squeezed by the baffle 801 and the rear protective plate 1 due to the unchanged distance between the front and rear protective plates after the rubber ring 803 expands, thus improving user comfort.

[0050] After wading through water, remove the inflation mechanism 4, press the baffle 801 to expel the gas inside the rubber ring 803. After the gas is expelled, the slide plate 617 lacks gas pressure. At this time, move the insert plate 601 to the innermost part of the slot 608. At this time, the limiting post 606 is aligned with the limiting groove. Since the spring 613 is in a compressed state, the moving plate 612 will drive the limiting post 606 into the limiting groove under the action of the spring 613, thereby limiting the insert plate 601, so that the distance between the front protective plate 3 and the rear protective plate 1 is restored to the distance when the rubber ring 803 is not inflated. Finally, insert the cylinder 904 on the baffle 801 into the round hole 901 on the air duct 902, and then pull up the zipper 805.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
