[0033] Example 1

[0034] like Figures 1 to 3 The first embodiment of a life raft support of the utility model is shown, comprising a base 1, at least two baffles 2 and at least two fastening mechanisms 3, the fastening mechanism 3 comprising a connector 33 and a fastener 34, the base 1 is rotatably connected to the baffle 2 via the connector 33, the fastener 34 is mounted at the end of the connector 33, the two baffles 2 are respectively arranged at the two ends of the base 1 facing each other, when the baffle 2 is rotated to contact the ground, it is in the unfolded state, when the baffle 22 is rotated to form a certain angle with the base 1, and a storage space is formed between the two baffles 2 and the base 1, it is in the use state. The life raft is generally folded and stored in the raft shell, such an arrangement can protect the life raft from being damaged by external objects, and is also convenient for rapid deployment on the water surface in the event of a failure, allowing staff to evacuate quickly. The base 1 is rotatably connected to the baffle door 2. When the raft shell needs to be stored, the baffle door 22 is rotated to form a certain angle with the base 1. When the angle is 90°, the base 1 and the baffle door 2 present a U-shaped structure. Through the fixation of the fastening mechanism 3, the base 1 and the baffle door 2 maintain the U-shaped structure, and the raft shell can be placed therein for fixation. When the life raft needs to be transferred, the fastening mechanism 3 is loosened, the baffle door 2 is rotated, one end of the baffle door 2 is in contact with the ground, and the other end is connected to the base 1. The staff can gently push the raft shell to make it roll to the ground along the baffle door 2. After the raft shell is transferred, the baffle door 2 is rotated to the upper end of the base 1 and placed. The operation is simple and quick, the work efficiency is high, and a small number of people are required.

[0035] A limiting mechanism 11 is installed at the top of the base 1, a cavity is provided inside the raft shell to store the life raft, and a plurality of protrusions are provided outside the raft shell. When the raft shell is placed on the upper end of the base, the limiting mechanism 11 and the protrusions of the raft shell work together to ensure that the raft shell is not easy to move when the raft shell is stored, so as to avoid the raft shell with the life raft falling, thereby avoiding equipment damage and injuries to staff. The life raft is generally stored in the raft shell, and the bracket for storing the life raft should firmly fix the life raft on the bracket when the life raft is stored to avoid the life raft from moving or falling. At the same time, the storage of the life raft should also take into account the angle for easy use.

[0036] The fastening mechanism 3 includes a connector 33 and a fastener 34. The base 1 is connected to the baffle 2 through the connector 33. The fastener 34 is installed at the end of the connector 33. The baffle 2 is rotatably connected to the base 1. The fastener 34 is loosened to allow the baffle 2 to rotate to a specified position. The fastener 34 is then tightened to fix the baffle 2 at the specified position. In this embodiment, the connector 33 is a threaded rod, and the fastener 34 is a threaded sleeve. The connector 33 and the fastener 34 are threadedly connected. The inclined surface design of the thread can generate friction when tightening to prevent the connection from loosening automatically when subjected to force, thereby ensuring that the raft shell will not fall off during transportation due to the loosening of the fastening mechanism 3, causing injuries to workers. The manufacture and use of the threaded connection are relatively simple and low in cost, and are suitable for large-scale production. Moreover, by using tools such as torque wrenches, the tightening torque of the threaded connection can be accurately controlled to ensure the reliability of the connection. In addition, the state of the threaded connection can be easily evaluated by visual or manual inspection, which is helpful for maintenance and quality control. In this embodiment, the fastening mechanism 3 uses a threaded rod and a threaded sleeve for fastening, but is not limited to this. The fastening mechanism 3 can also use a snap connection, a pin connection, etc. for fastening. The selection should be made considering the strength, durability, disassembly, cost, weight, and environmental factors of the connection.

[0037] The blocking door 2 of this embodiment includes a first blocking door 21 and a second blocking door 22, and the fastening mechanism 3 includes a first fastening mechanism 31 and a second fastening mechanism 32. One end of the base 1 is connected to the first blocking door 21 through the first fastening mechanism 31, and the other end of the base 1 is connected to the second blocking door 22 through the second fastening mechanism 32. By loosening the first fastener 34 and the second fastener 34, the first blocking door 21 and the second blocking door 22 can rotate freely relative to the base 1. When the first blocking door 21 rotates to the top of the base 1 and is vertical to the base 1, the first fastening mechanism 31 is tightened so that the first blocking door 21 remains vertical to the base 1 and is fixed. When the second baffle door 22 rotates to above the base 1 and is perpendicular to the base 1, the second fastening mechanism 32 is tightened to keep the second baffle door 22 vertically fixed to the base 1. At this time, the first baffle door 21, the base 1, and the second baffle door 22 are in a U-shaped structure, and the raft shell with the life raft is put in from the opening of the U-shaped structure; when the raft shell needs to be transferred out of the life raft bracket, the first fastening mechanism 31 is loosened so that the first baffle door 21 can rotate relative to the base 1, and the first baffle door 21 rotates around the base 1 with one end grounded. At this time, the first baffle door 21, the base 1, and the second baffle door 22 are in an L-shaped structure, and the raft shell rolls along the first baffle door 21 to realize the transfer of the life raft. The base 1, the first baffle 21 and the second baffle 22 of the utility model are all made of carbon steel, which has good mechanical strength and can withstand large loads. At the same time, carbon steel is easy to cut, weld and form, and is suitable for various processing techniques. The surface of carbon steel can be painted to provide an additional protective layer or improve the appearance to prevent the life raft bracket from being corroded. In addition, it can also be made of stainless steel, which has excellent corrosion resistance and is suitable for use in humid or chemical environments. Due to its corrosion resistance, the maintenance cost is low. The base 1, the first baffle 21 and the second baffle 22 of the utility model are made of carbon steel or stainless steel, which does not mean that it is limited to this. The specific requirements of the application can be considered, such as environmental conditions, cost budget, aesthetic requirements, maintenance frequency and other factors for specific selection.

[0038] The end of the first baffle 21 of the utility model is equipped with an inclined plate 211 away from the base 1. The use of the inclined plate 211 can reduce the force required for manual handling, especially for heavier goods. The inclined plate 211 allows the goods to be moved to a lower place more quickly, speeding up the handling speed, and reducing manual handling. It can reduce the risk of injury caused by carrying heavy objects, such as waist injury or muscle strain; for the cylindrical raft hull, the inclined plate 211 can allow the raft hull to roll and reduce the vibration and impact of the raft hull during the movement, thereby protecting the life raft.

[0039] The bottom end of the base 1 of the utility model is equipped with a supporting foot 5, which can prop up the entire life raft bracket and the life raft hull to prevent the life raft bracket from directly contacting the ground, away from ground water, and reduce the impact of the humid environment on the life raft bracket and the hull equipped with the life raft. Furthermore, the supporting foot 5 can also be equipped with a universal pulley with a brake, so that the life raft bracket can be easily moved and the transfer of the life raft can be better achieved. At the same time, the brake can ensure that the life raft bracket will not move due to external force, providing better stability, and the universal pulley with a brake can be quickly locked or released, which increases the flexibility of operation, reduces the wear caused by frequent movement, and extends its service life. In summary, the installation of a universal pulley with a brake can not only improve the safety and controllability of operation, but also increase the durability of the equipment.

[0040] Example 2

[0041] like Figures 4 to 7 The second embodiment of a life raft support of the utility model is shown. This embodiment is similar to the first embodiment, except that this embodiment further includes a plurality of restraining mechanisms 4, one end of the restraining mechanism 4 is movably connected to the end of the second stop door 22 away from the base 1, and the other end is a free end. The free end of the restraining mechanism 4 is detachably connected to the first stop door 21, and the end of the second stop door 22 away from the base 1 is equipped with a plurality of ring bodies 221, and the end of the restraining mechanism 4 connected to the second stop door 22 is provided with a plurality of buckles 41, and the buckles 41 are buckled with the ring bodies 221. The number of the restraining mechanisms 4 corresponds to the number of the ring bodies 221, and the buckle connection between the ring bodies 221 and the buckles 41 provides a certain activity space for the restraining mechanisms 4, and the buckle 41 of this embodiment has a simple structure, and wear and damage are easy to observe, which is helpful for inspection and maintenance, and does not require complicated maintenance. It only needs to be checked regularly whether it is intact. The buckle 41 of the restraining mechanism 4 can also be replaced with a quick connection buckle, which can not only achieve quick connection and quick disconnection, but also can be used in harsh environments.

[0042] The restraining mechanism 4 of the utility model is provided with a hook at the end away from the second baffle door 22, and the first baffle door 21 is provided with a hook at the end away from the base 1, and the hook and the hook 212 can be hooked. That is, when the life raft is stored using the utility model, the first baffle door 21, the base 1, and the second baffle door 22 are in a U-shaped structure and are fixed by the fastening mechanism 3. The hook of the restraining mechanism 4 is hooked with the hook 212 at the end of the first baffle door 21 to prevent the life raft from falling, thereby avoiding losses and potential accidents. Before using the restraining mechanism 4, it is necessary to check whether there is wear or damage, and replace it if necessary. When using it, it is necessary to ensure that the restraining mechanism 4 and the fastening mechanism 3 are properly fastened and not loose. In case of rainy and snowy weather, the surface of the raft shell may become slippery, and the fastening force of the restraining mechanism 4 needs to be increased. Appropriate waterproof measures need to be taken on the restraining mechanism 4 and the surface of the raft shell to prevent the fixing effect from being affected by slippery weather. In addition, the restraining mechanism 4 can be made of high temperature resistant material to avoid damage caused by overheating of the restraining mechanism 4 due to long-term exposure to direct sunlight, thereby avoiding accidents. The restraint mechanism 4 of this embodiment is made of polytetrafluoroethylene, which has excellent wear resistance and can maintain the performance of the restraint mechanism 4 for a long time, reduce wear and extend the life of the restraint mechanism 4; the life raft and the raft shell may carry liquids such as seawater that are prone to corrosion, and polytetrafluoroethylene has extremely high resistance to almost all chemical substances, including acids, alkalis and organic solvents, and is suitable for use in corrosive environments; at the same time, polytetrafluoroethylene has good aging resistance, is not easily affected by ultraviolet rays and oxidation, and is suitable for long-term exposure to the outdoors; and the density of polytetrafluoroethylene is low, which helps to reduce the overall weight of the utility model, making it easy to carry and install. Furthermore, polytetrafluoroethylene can maintain its performance at extreme temperatures, and the highest temperature can reach about 260 degrees Celsius, making it suitable for high-temperature exposure environments. The fact that the restraint mechanism 4 of the utility model is made of polytetrafluoroethylene does not mean that it is limited to this. The specific requirements of the application, such as environmental conditions, cost budget, aesthetic requirements, maintenance frequency and other factors can be considered for specific selection.

[0043] The buckle 41 and the ring body 221 of the present embodiment are made of stainless steel. Stainless steel has excellent corrosion resistance and is suitable for use in humid or chemical environments. Due to its corrosion resistance, the maintenance cost is low. The buckle 41 and the ring body 221 of the present embodiment can also be made of carbon steel. At the same time, carbon steel is easy to cut, weld and form, and is suitable for various processing techniques. In addition, carbon steel can be heat treated to improve its hardness and strength. The buckle 41 and the ring body 221 of the utility model are made of carbon steel or stainless steel, which does not mean that it is limited to this. The specific requirements of the application, such as environmental conditions, cost budget, aesthetic requirements, maintenance frequency and other factors can be considered for specific selection. For example, the utility model will be exposed to high humidity or corrosive environments, and stainless steel may be a better choice. If cost is a key factor, carbon steel may be a more appropriate choice.

[0044] Example 3

[0045] like Figure 8 This is the third embodiment of a life raft bracket of the utility model. This embodiment is similar to the second embodiment, except that the first baffle door 21 of this embodiment includes a baffle door frame 213 and a plurality of cross bars 214. The plurality of cross bars 214 are installed in the baffle door frame 213, and both ends of the cross bars 214 are fixedly connected to the baffle door frame 213. The cross bars 214 can improve the rigidity and stability of the first baffle door 21, help to more evenly disperse the load on the baffle door frame 213, reduce stress concentration in a single part, prevent the first baffle door 21 from twisting or deforming when subjected to force, and can significantly increase the load-bearing capacity. At the same time, it can also prevent the raft shell equipped with the life raft from slipping. The cross bars 214 can be added or removed as needed. Compared with other reinforcement methods, adding the cross bars 214 is low-cost and high-effective. The design and use of the cross bars 214 should be determined according to the specific application and expected load of the utility model to ensure its functionality and safety. In this embodiment, the first baffle door 21 is provided with a cross bar 214 but is not limited to the cross bar 214 . A diagonal support may be provided inside the baffle door 2 , and a bottom plate or a top plate may be added to improve the bending and torsional resistance of the first baffle door 21 .

[0046] Compared with the purchase and maintenance of professional handling equipment, such as using a crane to lift and lower the life raft, the use of a life raft bracket has a lower cost. The raft shell can be transferred by loosening the fastening mechanism 3 and lowering the baffle 2. The operation is simple and the work efficiency is high. In addition, the use of the utility model does not require special training, only safety training is required, and employees can quickly master the skills and start working.
