Description

Technical Field

[0001] This invention relates to the field of emergency breathing, and more particularly to an emergency breathing decompression cylinder assembly. Background Technology

[0002] Emergency breathing air cylinders are devices used to provide breathing air in emergency situations. They can provide necessary respiratory protection for firefighters, rescuers, and others.

[0003] Existing emergency breathing decompression cylinders are usually placed on a holder, which is then placed in the emergency area for use by firefighters, paramedics, and others. However, since the holder is usually straight and cannot be bent, it cannot fit snugly against a curved wall, requiring a large amount of space in the emergency area, which is inconvenient.

[0004] Therefore, an emergency breathing decompression cylinder assembly has now been developed that can adjust the angle between the containers, allowing the containers to bend and fit against the wall, thus saving space in the emergency area. Summary of the Invention

[0005] To overcome the shortcomings of existing emergency breathing decompression cylinders, which cannot fit snugly against a curved wall and require a large amount of space in the emergency area, this invention provides an emergency breathing decompression cylinder assembly that can adjust the angle between the holding seats so that the holding seats can bend to fit snugly against the wall, thus saving space in the emergency area.

[0006] An emergency breathing decompression cylinder assembly includes a decompression cylinder, a base, side shoulder seats, a holding seat, a double-opening shaft, a top gate mechanism, and a tail bending mechanism. There are two bases, each with a side shoulder seat connected to its upper side. Four sets of holding seats are arranged side by side between the side shoulder seats. Each set consists of three holding seats arranged vertically. A decompression cylinder is placed on each holding seat. A double-opening shaft is rotatably connected between two adjacent holding seats. A top gate mechanism that controls the opening and closing of the decompression cylinder is provided on the double-opening shaft. A tail bending mechanism that controls the bending degree of the holding seat is provided on the base.

[0007] To further explain, the top-lock mechanism includes columns, sleeves, ring rods, a central diaphragm ring, air pipes, airlock heads, and a fixed outer cover. Columns are connected to the upper side of the double-opening shaft. Sleeves are connected to the upper left and right sides of the columns, and ring rods are connected to the sleeves. Ring rods are also connected to the upper sides of the side shoulder seats, which are close to each other. Central diaphragm rings are connected to the ring rods, and adjacent central diaphragm rings are in contact with each other. Air pipes, which are flexible hoses, are snapped into each other. Airlock heads are snapped into the upper part of each pressure-reducing cylinder, and air pipes are connected to adjacent airlock heads. A fixed outer cover is snapped into the upper side of each pressure-reducing cylinder, and the airlock heads are slidably connected to adjacent fixed outer covers. Sliding the airlock head on the fixed outer cover downwards opens the pressure-reducing cylinder, simultaneously placing the air pipe at the mouth of the trapped person, allowing the oxygen in the pressure-reducing cylinder to be supplied for breathing.

[0008] To further explain, the tail bend mechanism includes a folding rod, a cam screw, a middle partition plate, a vertical frame, and a loop. Folding rods are connected to both the upper and lower parts of the base. Loops are rotatably connected to the upper rear part of the double-opening shaft in the middle and lower parts. The vertical frame is slidably connected to the loop. The lower side of the vertical frame is connected to a middle partition plate. A cam screw is threaded between two adjacent middle partition plates. A cam screw is threaded between the outermost middle partition plate and the adjacent folding rod. Rotating the cam screw adjusts the distance between the folding rod and the middle partition plate, and simultaneously adjusts the distance between the middle partition plates, causing the middle partition plate to drive the vertical frame to move. This causes the vertical frame to slide on the loop, and the loop rotates on the double-opening shaft, driving the double-opening shaft to rotate.

[0009] Further explanation: It also includes a fixing mechanism, which includes a compression spring, a pressure rod, diamond blocks, side pressure plates, and a return spring. Pressure rods are slidably connected to the lower holding seats, with the upper part of each pressure rod passing through the upper holding seat. A compression spring connects the lower part of each pressure rod to an adjacent lower holding seat. Multiple diamond blocks are connected to the left and right sides of each pressure rod. Side pressure plates are slidably connected to the left and right sides of the middle and lower holding seats, with each diamond block engaging with an adjacent side pressure plate. Return springs connect the front and rear parts of each side pressure plate to adjacent holding seats. At this time, the return spring is in a compressed state. The depressurized gas cylinder pushes the pressure rod downwards, causing the compression spring to contract, resulting in the diamond blocks moving downwards and disengaging from the side pressure plates. Then, the return spring rebounds, pushing the side pressure plates closer together to contact the depressurized gas cylinder.

[0010] Further explanation: It also includes a tail-mounting mechanism, which includes a bearing seat, a rotating seat, mounting pins, side plates, and a mounting bracket. Bearing seats are engaged between two adjacent middle partitions, and bearing seats are also engaged between the outermost middle partition and the adjacent folding rod. A rotating seat is rotatably connected to the upper side of each bearing seat, and multiple mounting pins are connected to each rotating seat. Side plates are connected to the upper part of each side shoulder seat, and mounting brackets are rotatably connected to the rear part of each side plate. Mounting pins are also connected to both the upper and lower parts of the mounting bracket. Rotating to adjust the angle of the rotating seat on the bearing seat, and then rotating to adjust the angle of the mounting bracket on the side plate, makes the mounting pins contact the emergency area wall, and then fixes the mounting pins to the emergency area wall.

[0011] To further explain, it also includes a protective mechanism, which includes a rotating rod, a side folding plate, and a folding plate. The rotating rod is rotatably connected to the front of the base, and the side folding plate is connected to the front of the rotating rod. The folding plate is rotatably connected between the upper and lower parts of the side folding plate. When the container rotates, it drives the base to move, causing the base to rotate on the rotating rod, while the side folding plate remains stationary, so that the folding plate is always located in front of the depressurized gas cylinder.

[0012] Further explanation: It also includes a sealing mechanism, which includes a top cover, a foam chamber, and an inner flow ring. Each pressure-reducing gas cylinder is connected to a foam chamber at the top, and a top cover is snapped onto the top side of each foam chamber. Each foam chamber is connected to an inner flow ring at the bottom side, and the inner flow ring is in contact with the adjacent pressure-reducing gas cylinder. Foam water is poured into the foam chamber, and then flows from the foam chamber to the inner flow ring. The inner flow ring guides the foam water to the surface of the pressure-reducing gas cylinder. When the foam water on the surface of the pressure-reducing gas cylinder bubbles, it indicates that gas is escaping from that location.

[0013] To further explain, both the left and right sides of the convex screw are equipped with turntables.

[0014] Beneficial effects: 1. By rotating the convex screw, the distance between the middle partitions is adjusted, so that the stand slides on the loop, the loop rotates on the double open shaft, and drives the double open shaft to rotate, thereby achieving the effect of adjusting the angle between the holding seats, so that the holding seats can be bent to fit against the wall, saving space in the emergency area.

[0015] 2. This invention uses a pressure cylinder to push a pressure rod downwards, compressing a spring and causing the diamond block to move downwards and disengage from the side pressure plate. Then, a return spring rebounds, pushing the side pressure plates closer together to contact the pressure cylinder, thus achieving the effect of clamping and fixing the pressure cylinder and preventing it from moving.

[0016] 3. This invention guides foam water to the surface of the depressurization cylinder through an internal flow ring. When the foam water on the surface of the depressurization cylinder bubbles, it indicates that gas is escaping from that location, thus achieving the effect of testing the sealing performance of the depressurization cylinder and preventing oxygen loss from the cylinder.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0026] An emergency breathing decompression cylinder assembly, such as Figure 1 and Figure 2 As shown, it includes a pressure-reducing gas cylinder 0, a base 1, a side shoulder seat 2, a holding seat 3, a double-opening shaft 4, a top gate mechanism 5, and a tail bend mechanism 6. There are two bases 1, and each base 1 is connected to a side shoulder seat 2. There are four sets of holding seats 3 arranged side by side between the side shoulder seats 2. Each set consists of three holding seats 3 arranged vertically. Each set of holding seats 3 holds a pressure-reducing gas cylinder 0. The two adjacent holding seats 3 are rotatably connected to a double-opening shaft 4. The double-opening shaft 4 is equipped with a top gate mechanism 5. The base 1 is equipped with a tail bend mechanism 6.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the top-lock mechanism 5 includes a column 51, a sleeve rod 52, a ring rod 53, a central partition ring 54, an air pipe 55, an airlock head 56, and a fixed outer cover 57. The upper double-opening shaft 4 is connected to the upper side of the column 51. The upper left and right sides of the column 51 are connected to the sleeve rod 52. The ring rod 53 is connected to the sleeve rod 52. The upper side of the side shoulder seat 2 is also connected to the ring rod 53. The central partition ring 54 is connected to the ring rod 53. The adjacent central partition rings 54 are in contact with each other. The air pipe 55 is clamped between the adjacent central partition rings 54. The air pipe 55 is a flexible hose. The upper part of the pressure-reducing gas cylinder 0 is clamped to the airlock head 56. The air pipe 55 is connected to the adjacent airlock head 56. The upper side of the pressure-reducing gas cylinder 0 is clamped to the fixed outer cover 57. The airlock head 56 is slidably connected to the adjacent fixed outer cover 57.

[0028] When using this invention, first place the base 1 in the emergency area, then place the depressurized gas cylinder 0 in the holding seat 3 on the side shoulder seat 2. After placement, adjust the distance between the holding seats 3 by rotating the double-opening shaft 4. When oxygen from the depressurized gas cylinder 0 is needed, slide the airlock head 56 on the outer cover 57 downward to open the depressurized gas cylinder 0. At the same time, place the air tube 55 at the mouth of the trapped person so that the oxygen from the depressurized gas cylinder 0 can be used for the trapped person to breathe. When adjusting the angle between the holding seats 3, the double-opening shaft 4 drives the column 51 to move, causing the ring rod 53 on the sleeve rod 52 to move and the middle partition ring 54 to move. After the holding seats 3 are adjusted, the middle partition ring 54 limits and supports the air tube 55 to prevent the air tube 55 from loosening and causing oxygen waste.

[0029] like Figure 1 and Figure 5 As shown, the tail bending mechanism 6 includes a folding rod 61, a convex screw 62, a middle partition plate 63, a vertical frame 64, and a loose sleeve 65. The upper and lower parts of the base 1 are connected to the folding rod 61. The upper rear part of the double-opening shaft 4 in the middle and lower parts is rotatably connected to the loose sleeve 65. The vertical frame 64 is slidably connected to the loose sleeve 65. The lower side of the vertical frame 64 is connected to the middle partition plate 63. The convex screw 62 is threaded between two adjacent middle partition plates 63. The outermost middle partition plate 63 is threaded with the convex screw 62 between it and the adjacent folding rod 61. The convex screw 62 is provided with turntables on both the left and right sides for easy rotation.

[0030] Using the tail bending mechanism 6 of this device, the angle between the holding seats 3 can be adjusted. By rotating the cam screw 62, the distance between the bending rod 61 and the middle partition 63 can be adjusted. At the same time, the distance between the middle partitions 63 is adjusted, and the middle partition 63 drives the upright frame 64 to move, so that the upright frame 64 slides on the loop 65. The loop 65 rotates on the double open shaft 4, which drives the double open shaft 4 to rotate. This allows the angle between the holding seats 3 to bend so that the holding seats 3 can be bent to fit against the wall, saving space in the emergency area.

[0031] like Figure 1 and Figure 3 As shown, it also includes a fixing mechanism 7, which includes a compression spring 71, a pressure rod 72, a diamond block 73, a side pressure plate 74, and a return spring 75. The pressure rod 72 is slidably connected to the lower holding seat 3. The upper part of the pressure rod 72 passes through the upper holding seat 3. The lower part of the pressure rod 72 is connected to the adjacent lower holding seat 3 by a compression spring 71. Two diamond blocks 73 are connected to the left and right sides of the pressure rod 72. The middle and lower holding seats 3 are slidably connected to the left and right sides of the side holding seats 3. The diamond blocks 73 are engaged with the adjacent side pressure plates 74. The front and rear parts of the side pressure plates 74 are connected to the adjacent holding seats 3 by a return spring 75. At this time, the return spring 75 is in a compressed state.

[0032] Using the fixing mechanism 7 of this device, the pressure-reducing gas cylinder 0 can be fixed. When the pressure-reducing gas cylinder 0 is placed in the holding seat 3, the pressure-reducing gas cylinder 0 pushes the pressure rod 72 to move downward, the compression spring 71 contracts, and the diamond block 73 moves downward and disengages from the side pressure plate 74. Then the return spring 75 rebounds, pushing the side pressure plates 74 to move closer to each other and contact the pressure-reducing gas cylinder 0, thereby clamping and fixing the pressure-reducing gas cylinder 0 and preventing the pressure-reducing gas cylinder 0 from moving.

[0033] like Figure 1 and Figure 5 As shown, it also includes a tail assembly mechanism 8, which includes a bearing seat 81, a rotating seat 82, mounting pins 83, a side plate 84, and a rotating bracket 85. The bearing seat 81 is engaged between two adjacent middle partitions 63, and the outermost middle partition 63 is also engaged with the adjacent folding rod 61 by a bearing seat 81. The rotating seat 82 is rotatably connected to the upper side of the bearing seat 81, and three mounting pins 83 are connected to the rotating seat 82. The side plate 84 is connected to the upper part of the side shoulder seat 2, and the rotating bracket 85 is rotatably connected to the rear part of the side plate 84. Mounting pins 83 are also connected to both the upper and lower parts of the rotating bracket 85.

[0034] Using the tail-mounting mechanism 8 of this device, the base 1 can be fixed in the emergency area. The angle of the adjusting seat 82 on the bearing seat 81 can be rotated and the angle of the adjusting mounting bracket 85 on the side plate 84 can be rotated and adjusted so that the mounting nail 83 contacts the wall of the emergency area. Then the mounting nail 83 is fixed to the wall of the emergency area, thereby fixing the base 1 in the emergency area and preventing the base 1 from moving.

[0035] like Figure 1 and Figure 6 As shown, it also includes a protective mechanism 9, which includes a rotating rod 91, a side folding plate 92 and a folding plate 93. The front part of the base 1 is rotatably connected to the rotating rod 91, the front side of the rotating rod 91 is connected to the side folding plate 92, and the upper and lower parts of the side folding plate 92 are rotatably connected to the folding plate 93.

[0036] Using the protective mechanism 9 of this device, the pressure-reducing gas cylinder 0 can be protected. When the holding seat 3 rotates, it drives the base 1 to move, so that the base 1 rotates on the rotating rod 91. The side folding plate 92 is fixed, so that the folding plate 93 is always located in front of the pressure-reducing gas cylinder 0, thereby protecting the pressure-reducing gas cylinder 0 and preventing it from being impacted.

[0037] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a sealing mechanism 10, which includes a top cover 101, a foam chamber 102 and an inner flow ring 103. The upper part of each pressure-reducing gas cylinder 0 is connected to a foam chamber 102, and the top cover 101 is snapped onto the upper side of each foam chamber 102. The lower side of each foam chamber 102 is connected to an inner flow ring 103, and the inner flow ring 103 is in contact with the adjacent pressure-reducing gas cylinder 0.

[0038] Using the sealing mechanism 10 of this device, the sealing performance of the depressurized gas cylinder 0 can be tested. The top cover 101 is removed, and foam water is poured into the foam chamber 102. The foam water then flows from the foam chamber 102 to the inner flow ring 103. The inner flow ring 103 guides the foam water to the surface of the depressurized gas cylinder 0. When the foam water on the surface of the depressurized gas cylinder 0 bubbles, it indicates that gas is escaping from that location. This serves to test the sealing performance of the depressurized gas cylinder 0 and prevent oxygen loss from the depressurized gas cylinder 0.
