Description

Technical Field

[0001] This utility model relates to the field of thermal insulation material fixing strips, and more particularly to a fuel tank thermal insulation material fixing strip. Background Technology

[0002] Fuel tank insulation securing straps are commonly used in aerospace, marine, or other high-temperature environments to secure insulation materials to the fuel tank or other critical components. These straps must possess sufficient strength to withstand high temperatures and pressures.

[0003] Existing technologies, such as the utility model patent with publication number CN216185802U, disclose a bulk carrier with an LNG fuel tank in the cargo hold area. This patent includes an LNG fuel tank within the cargo hold area of ​​the bulk carrier. The LNG fuel tank is a membrane-type tank, placed on the cargo hold floor. The cargo hold floor and the inner shell of the cargo hold enclose the outer surface of the LNG fuel tank. The inner shell of the cargo hold forms an air-tight compartment with the outer hull, transverse bulkheads, and upper deck. An insulating layer is laid on the side of the upper deck adjacent to the LNG fuel tank, and an insulating layer is laid on the side of the transverse bulkheads adjacent to the LNG fuel tank. Alternatively, the LNG fuel tank can be a type B or type C tank, fixed to the cargo hold floor by supports, and arranged in an enclosed space within the cargo hold area of ​​the ship. This LNG fuel tank structure has minimal impact on the overall longitudinal strength of the hull beams and a low center of gravity, ensuring the safety and stability of the bulk carrier during navigation. It is highly flexible, allowing for the installation of different types of LNG fuel tanks within the cargo hold area, and the LNG fuel tank can be placed at any location within the cargo hold area.

[0004] The inventors discovered during use that existing fixing straps often have the problem of inconvenient length adjustment when fixing different cans. Traditional fixing straps mostly use Velcro or buckle designs. Velcro tends to lose its adhesiveness after long-term use, resulting in a weakened fixing effect and low adjustment precision, making it difficult to accurately adapt to cans with different circumferences. Buckle designs require disassembling and re-attaching each buckle individually during adjustment, which is cumbersome, time-consuming, and reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in adjusting the length of the fixing strap.

[0006] To solve the above technical problems, this utility model provides a fuel tank insulation material fixing strap, comprising: a connecting strap, an insulation pad fixedly connected to the inner wall of the connecting strap, auxiliary structures provided on the inner walls of both ends of the connecting strap, the auxiliary structures including two extension straps, the two extension straps being slidably connected to the two ends of the connecting strap respectively, a plurality of insertion holes slidably opened on the inner wall of the extension strap, a connecting frame fixedly connected to the end of one of the extension straps away from the connecting strap, and sliding grooves opened on both the upper and lower sides of the connecting frame, with sliders slidably connected to the inner walls of the sliding grooves. A sliding frame is fixedly connected to the side of the slider away from the sliding groove. A fixing block is fixedly connected to the side of the sliding frame near the connecting frame. The fixing block is adapted to the insertion hole. A spring is installed inside the sliding groove. The two ends of the spring are fixedly connected to the sliding groove and the slider, respectively. Two connecting plates are slidably connected to the inner wall of the connecting strip. A stop plate is fixedly connected to the end of each connecting plate that is close to each other. The stop plate is embedded inside the heat insulation pad. A slot is opened on the inner wall of the connecting plate. An auxiliary plate is slidably connected to the inner wall of the slot. The auxiliary plate fits against the connecting strip. The effect achieved by the above components is that when it is necessary to use the connecting strip to fix the tank, the extension length of the two extension strips at both ends of the connecting strip can be adjusted according to the circumference of the tank so that the connecting frame can be fitted onto the extension strip on the other side. Next, slide the sliding frame, causing the fixing block to compress the spring and move away from the connecting frame. After the connecting frame is fitted into the appropriate position of the extension strip, release the sliding frame. The spring returns to its original deformation and pushes the fixing block into the corresponding socket, thereby fixing the extension strip to the connecting frame. This allows for quick adjustment of the connecting strip length to accommodate tanks of different sizes. When the length of the connecting strip needs to be adjusted, first pull the auxiliary plate away from the connecting strip so that it slides out of the slot and is no longer in contact with the connecting strip. Then, slide the connecting plate to move the abutment plate inside the heat insulation pad and adjust the support position of the abutment plate on the heat insulation pad. When the connecting plate moves to the appropriate position, reinsert the auxiliary plate into the slot and make it fit tightly against the inner wall of the connecting strip. Use the friction between the auxiliary plate and the connecting strip to limit the sliding of the connecting plate, thereby further enhancing the structural stability of the connecting strip during the fixing process and preventing displacement of the connecting strip due to tank shaking.

[0007] Preferably, the auxiliary plate has several friction grooves on both sides, and the friction grooves are evenly distributed on both sides of the auxiliary plate. The effect achieved by the above component is that the friction grooves increase the friction between the hand and the auxiliary plate, preventing slippage when the auxiliary plate is pulled.

[0008] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the side of the auxiliary plate near the connecting strip. The effect achieved by the above components is that the anti-slip pad can increase the friction between the auxiliary plate and the connecting strip, preventing slippage when the connecting strip and the auxiliary plate are in contact.

[0009] Preferably, a limiting rod is fixedly connected inside the slide groove, the limiting rod is slidably connected to the slider, and the spring is sleeved on the arc surface of the limiting rod. The effect achieved by the above components is that the limiting rod can limit the spring, preventing the spring from deforming during use and improving the service life of the spring.

[0010] Preferably, the sliding frame has several auxiliary grooves on both its upper and lower sides, and these auxiliary grooves are evenly distributed on both sides. The effect achieved by the above components is that the auxiliary grooves can increase the friction between the sliding frame and the hand, preventing slippage when the sliding frame is pulled.

[0011] Preferably, an anti-slip sleeve is fixedly connected to the surface of the fixing block, and the cross-section of the anti-slip sleeve is a hollow rectangle. The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the fixing block and the insertion hole, and prevent slippage when the anti-slip sleeve is connected to the fixing block.

[0012] Compared with related technologies, the fuel tank insulation material fixing strip provided by this utility model has the following beneficial effects: This utility model provides a fuel tank insulation material fixing strap. By setting an auxiliary structure, the length of the connecting strap can be flexibly adjusted according to tanks of different sizes. The structural stability of the connecting strap during fixing is enhanced by adjusting the position of the abutment plate. This effectively solves the problem that traditional connecting straps are difficult to adapt to various tank sizes due to their fixed length and are prone to displacement when the tank shakes. It improves the adaptability and reliability of the connecting strap for fixing the tank and ensures the safety and stability of the insulation material fixing strap during use.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 6 The present invention provides a fuel tank insulation material fixing strap, comprising: a connecting strap 1, an insulation pad 2 fixedly connected to the inner wall of the connecting strap 1, and auxiliary structures 3 provided on the inner walls at both ends of the connecting strap 1.

[0018] In the embodiments of this utility model, please refer to Figures 1 to 6The auxiliary structure 3 includes two extension strips 304, which are slidably connected to both ends of the connecting strip 1. Several insertion holes 305 are slidably opened on the inner wall of each extension strip 304. A connecting frame 301 is fixedly connected to one end of one extension strip 304 away from the connecting strip 1. Slide grooves 310 are opened on both the upper and lower sides of the connecting frame 301. A slider 308 is slidably connected to the inner wall of the slide groove 310. A sliding frame 302 is fixedly connected to the side of the slider 308 away from the slide groove 310. A component is fixedly connected to the side of the sliding frame 302 closest to the connecting frame 301. A fixing block 306 is fitted to an insertion hole 305. A spring 311 is installed inside the sliding groove 310. The two ends of the spring 311 are fixedly connected to the sliding groove 310 and the slider 308, respectively. Two connecting plates 314 are slidably connected to the inner wall of the connecting band 1. Abutment plates 316 are fixedly connected to the ends of the two connecting plates 314 that are close to each other. The abutment plates 316 are embedded inside the heat insulation pad. A slot 318 is opened on the inner wall of the connecting plate 314. An auxiliary plate 312 is slidably connected to the inner wall of the slot 318. The auxiliary plate 312 fits against the connecting band 1. When it is necessary to use the connecting band 1 to fix the tank, the extension length of the two extension bands 304 at both ends of the connecting band 1 can be adjusted according to the circumference of the tank so that the connecting frame 301 can be fitted onto the extension band 304 on the other side. Next, slide the sliding frame 302, causing the fixing block 306 to compress the spring 311 and move away from the connecting frame 301. After the connecting frame 301 is fitted into the appropriate position of the extension belt 304, release the sliding frame 302. The spring 311 returns to its original deformation, pushing the fixing block 306 into the corresponding insertion hole 305, thereby fixing the extension belt 304 to the connecting frame 301. This allows for quick adjustment of the length of the connecting belt 1 to accommodate tanks of different sizes. When it is necessary to adjust the length of the connecting belt 1, first pull the auxiliary plate 312 away from the connecting belt 1, causing it to slide out of the slot 318 and disengage from the contact state with the connecting belt 1. Then, the extension belt 304 can be slid... The movable connecting plate 314 drives the abutment plate 316 to move inside the heat insulation pad, adjusting the support position of the abutment plate 316 on the heat insulation pad. After the connecting plate 314 moves to the appropriate position, the auxiliary plate 312 is reinserted into the slot 318 and made to fit tightly against the inner wall of the connecting band 1. The friction between the auxiliary plate 312 and the connecting band 1 restricts the sliding of the connecting plate 314, thereby further enhancing the structural stability of the connecting band 1 during the fixing process and preventing displacement of the connecting band 1 due to tank shaking. Several friction grooves 317 are provided on both sides of the auxiliary plate 312, and the friction grooves 317 are evenly distributed on both sides of the auxiliary plate 312. The friction grooves 317 increase the friction between the hand and the auxiliary plate 312, preventing slippage when the auxiliary plate 312 is pulled. An anti-slip pad 313, which is a rubber pad, is fixedly connected to the side of the auxiliary plate 312 near the connecting band 1.The anti-slip pad 313 increases the friction between the auxiliary plate 312 and the connecting strip 1, preventing slippage when the connecting strip 1 and the auxiliary plate 312 are in contact. A limiting rod 309 is fixedly connected inside the slide groove 310, and the limiting rod 309 is slidably connected to the slider 308. A spring 311 is sleeved on the arc surface of the limiting rod 309. The limiting rod 309 limits the spring 311, preventing deformation during use and improving its service life. Several auxiliary grooves 303 are evenly distributed on the upper and lower sides of the slide frame 302. The auxiliary grooves 303 increase the friction between the slide frame 302 and the hand, preventing slippage when the slide frame 302 is pulled. An anti-slip sleeve 307 is fixedly connected to the surface of the fixing block 306; the anti-slip sleeve 307 has a hollow rectangular cross-section. The anti-slip sleeve 307 can increase the friction between the fixing block 306 and the insertion hole 305, and prevent the anti-slip sleeve 307 from sliding when it is connected to the fixing block 306. The working principle of the fuel tank insulation material fixing strap provided by this utility model is as follows: When it is necessary to use the connecting strap 1 to fix the tank, the extension length of the two extension straps 304 at both ends of the connecting strap 1 can be adjusted according to the circumference of the tank so that the connecting frame 301 can be fitted onto the extension strap 304 on the other side. Next, slide the sliding frame 302, causing the fixing block 306 to compress the spring 311 and move away from the connecting frame 301. After the connecting frame 301 is fitted into the appropriate position of the extension belt 304, release the sliding frame 302. The spring 311 returns to its original deformation and pushes the fixing block 306 into the corresponding insertion hole 305, thereby fixing the extension belt 304 to the connecting frame 301. This allows for quick adjustment of the length of the connecting belt 1 to accommodate tanks of different sizes. When it is necessary to adjust the length of the connecting belt 1, first pull the auxiliary plate 312 away from the connecting belt 1, so that it slides out of the slot 318 and is no longer in contact with the connecting belt 1. Then, slide the connecting plate 314 to move the abutment plate 316 inside the heat insulation pad, adjusting the support position of the abutment plate 316 on the heat insulation pad. When the connecting plate 314 moves to the appropriate position, reinsert the auxiliary plate 312 into the slot 318 and make it fit tightly against the inner wall of the connecting belt 1. The friction between the connecting plate 314 and the connecting strip 1 restricts the sliding of the connecting plate 314, thereby further enhancing the structural stability of the connecting strip 1 during the fixing process and preventing displacement of the connecting strip 1 due to shaking of the tank. The friction groove 317 increases the friction between the hand and the auxiliary plate 312, preventing slippage when the auxiliary plate 312 is pulled. The anti-slip pad 313 can increase the friction between the auxiliary plate 312 and the connecting strip 1, preventing slippage when the connecting strip 1 and the auxiliary plate 312 are in contact. The limiting rod 309 can limit the spring 311, preventing deformation of the spring 311 during use and improving the service life of the spring 311. The auxiliary groove 303 can increase the friction between the sliding frame 302 and the hand, preventing slippage when the sliding frame 302 is pulled. The anti-slip sleeve 307 can increase the friction between the fixing block 306 and the insertion hole 305, preventing slippage when the anti-slip sleeve 307 and the fixing block 306 are connected.
