Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polyurethane insulation boards, and particularly relates to a polyurethane insulation board with strong extrusion resistance. Background Technique
[0002] In the existing fields of architecture and cold chain logistics, as an energy-efficient thermal insulation material, polyurethane insulation boards are widely used in scenarios such as walls, roofs, refrigerated trucks, and cold chain logistics boxes. However, in practical applications, polyurethane insulation boards often face extrusion from the external environment or internal loaded items, which easily causes the insulation boards to deform or even rupture, seriously affecting their thermal insulation performance and structural integrity.
[0003] Most traditional polyurethane insulation boards are designed to focus on improving thermal insulation performance, but they are insufficient in terms of extrusion resistance. Especially in the cold chain logistics field, with the continuous vibration of logistics boxes during transportation and the pressure of cargo stacking, polyurethane insulation boards are easily damaged by extrusion, thereby affecting the temperature control of the goods in the box and causing the quality of items such as food and medicine to decline.
[0004] To solve the above problems, although some improvement schemes have emerged in the prior art, such as increasing the thickness of the insulation board or using harder materials, these methods often increase the weight and cost of the insulation board and do not necessarily effectively improve its extrusion resistance. At the same time, these improvement schemes also ignore the convenience and maintainability of polyurethane insulation boards in actual use.
[0005] Therefore, a polyurethane insulation board with strong extrusion resistance is proposed. Summary of the Invention
[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a polyurethane insulation board with strong extrusion resistance is proposed.
[0007] To achieve the above purpose, the utility model provides the following technical solution: A polyurethane insulation board with strong extrusion resistance, including a polyurethane board, a fixing frame is detachably installed on the polyurethane board, fixing plates are detachably installed on both sides of the polyurethane board and the fixing frame, a protective plate is installed on one side of the fixing plate, the protective plate is parallel to the fixing plate, telescopic components are installed at the four corners between the protective plate and the fixing plate, and a number of elastic components are installed between the protective plate and the fixing plate.
[0008] By adopting the above technical solution, the fixing frame can not only facilitate installation and disassembly, but also reinforce the polyurethane board on the side of the polyurethane board, enabling the polyurethane board to withstand stronger extrusion force. After the fixing plates arranged on both sides of the polyurethane board are installed on the fixing frame, the protective plates can be connected through the telescopic components. There is a spacing between the protective plates and the fixing plates, and this spacing is the buffer space in actual application. The protective plates can perform buffer movement in the buffer space through the telescopic components. At the same time, a number of elastic components installed between the protective plates and the fixing plates can effectively absorb the extrusion force received by the protective plates, thereby effectively preventing the extrusion of the polyurethane board and enhancing the anti-extrusion ability of the polyurethane board.
[0009] Preferably, the fixing frame is sleeved and installed on the side wall of the polyurethane board. Countersunk holes are provided in the upper and lower parts of both side walls of the fixing frame, and the countersunk holes penetrate through the side wall of the fixing frame. First hexagon socket head cap screws are installed in the countersunk holes by threading.
[0010] When the first hexagon socket head cap screw is tightened in the direction of the polyurethane board, the end face of the screw rod of the first hexagon socket head cap screw abuts against the side wall of the polyurethane board.
[0011] By adopting the above technical solution, the disassembly and installation of the fixing frame and the polyurethane board are realized. Loosen the first hexagon socket head cap screw, and the fixing frame can be disassembled. Tightening the first hexagon socket head cap screw can fasten the fixing frame and the polyurethane board.
[0012] Preferably, second hexagon socket head cap screws are installed by threading at the four corners of the outer side wall of the fixing plate. The fixing plate and the fixing frame are firmly connected through the second hexagon socket head cap screws.
[0013] By adopting the above technical solution, by loosening or tightening the second hexagon socket head cap screws, the fixing plate can be disassembled or installed.
[0014] Preferably, the telescopic component includes a sleeve and a sliding rod. One end face of the sleeve is fixedly connected to the outer side wall of the fixing plate. One end of the sliding rod is inserted and installed in the sleeve and is slidably connected to the sleeve. The end face of the sliding rod away from the sleeve is fixedly connected to the side wall of the protective plate facing the fixing plate.
[0015] Wherein, one end of the sliding rod located in the inner cavity of the sleeve has a limiting ring, and a ring-shaped limiting piece is integrally formed at the top of the sleeve. The outer side wall of the limiting ring is slidably connected to the inner wall of the sleeve.
[0016] By adopting the above technical solution, through the sliding of the sliding rod in the sleeve, the protective plate can perform buffer movement relative to the fixing plate in the buffer space between the protective plate and the fixing plate. Under the action of the limiting ring of the sliding rod and the ring-shaped limiting piece at the top of the sleeve, the sliding rod can be prevented from slipping off.
[0017] Preferably, the elastic member is a rubber column. One ends of a plurality of the rubber columns are fixedly connected to the outer side wall of the fixing plate, and the other ends are fixedly connected to the side wall of the protection plate facing the fixing plate.
[0018] By adopting the above technical solution, the rubber column can effectively absorb the extrusion force, further optimizing the implementation manner of the elastic member. At the same time, when the rubber column resets, it can push the protection plate outwards under the guiding action of the sliding rod and the sleeve.
[0019] Preferably, a plurality of the rubber columns are equidistantly distributed in a matrix between the fixing plate and the protection plate.
[0020] By adopting the above technical solution, the buffering effect of the protection plate is more uniform when the protection plate is subjected to an extrusion force.
[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0022] First, in the present utility model, the fixing frame can not only facilitate installation and disassembly, but also reinforce the polyurethane board on the side surface of the polyurethane board, so that the polyurethane board can withstand a stronger extrusion force.
[0023] Second, in the present utility model, after the fixing plates arranged on both sides of the polyurethane board are installed on the fixing frame, the protection plates can be connected through the telescopic members. There is a spacing between the protection plate and the fixing plate, and this spacing is the buffer space in practical applications. The protection plate can perform buffer movement in the buffer space through the telescopic members. At the same time, a plurality of elastic members installed between the protection plate and the fixing plate can effectively absorb the extrusion force received by the protection plate, thereby effectively preventing the extrusion of the polyurethane board, enhancing the anti-extrusion ability of the polyurethane board, and avoiding being damaged by the edges and corners of the boxed goods.
[0024] Third, in the present utility model, through the countersunk holes and the first inner hexagon bolts, the disassembly and installation of the fixing frame and the polyurethane board are realized. By loosening the first inner hexagon bolts, the fixing frame can be disassembled, and by tightening the first inner hexagon bolts, the fixing frame and the polyurethane board can be fastened together.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model. Embodiment
[0038] Please refer to Figures 1-9 , this embodiment provides the following technical solutions:
[0039] As Figures 1-9As shown in the figure, a polyurethane insulation board with strong anti-extrusion ability includes a polyurethane board 1. A fixing frame 2 is detachably installed on the polyurethane board 1. Fixing plates 3 are detachably installed on both sides of the polyurethane board 1 and the fixing frame 2. A protective plate 7 is installed on one side of the fixing plate 3. The protective plate 7 is parallel to the fixing plate 3. Telescopic components are installed at the four corners between the protective plate 7 and the fixing plate 3. A number of elastic components are installed between the protective plate 7 and the fixing plate 3.
[0040] The fixing frame 2 can not only facilitate installation and disassembly, but also reinforce the polyurethane board 1 from the side of the polyurethane board 1, enabling the polyurethane board 1 to withstand stronger extrusion force. After the fixing plates 3 arranged on both sides of the polyurethane board 1 are installed on the fixing frame 2, the protective plate 7 can be connected through the telescopic components. There is a spacing between the protective plate 7 and the fixing plate 3, and this spacing is the buffer space in actual application. The protective plate 7 can perform buffer movement in the buffer space through the telescopic components. At the same time, a number of elastic components installed between the protective plate 7 and the fixing plate 3 can effectively absorb the extrusion force received by the protective plate 7, thereby effectively preventing the polyurethane board 1 from being extruded and enhancing the anti-extrusion ability of the polyurethane board 1. Embodiment
[0041] Improved on the basis of Embodiment 1:
[0042] As Figures 1-9 As shown in the figure, in order to realize the disassembly and installation of the fixing frame 2 and the polyurethane board 1, the fixing frame 2 is sleeved on the side wall of the polyurethane board 1. Countersunk holes 21 are opened at the upper and lower parts of both side walls of the fixing frame 2. The countersunk holes 21 penetrate through the side wall of the fixing frame 2. First hexagon socket head cap screws 22 are threadedly installed in the countersunk holes 21;
[0043] When the first hexagon socket head cap screw 22 is tightened in the direction of the polyurethane board 1, the end face of the screw rod of the first hexagon socket head cap screw 22 abuts against the side wall of the polyurethane board 1, thereby realizing the disassembly and installation of the fixing frame 2 and the polyurethane board 1. Loosen the first hexagon socket head cap screw 22, and the fixing frame 2 can be disassembled. Tightening the first hexagon socket head cap screw 22 can fasten the fixing frame 2 and the polyurethane board 1 together.
[0044] In order to enable the fixing plate 3 to be disassembled or installed, second hexagon socket head cap screws 4 are threadedly installed at the four corners of the outer side wall of the fixing plate 3. The fixing plate 3 and the fixing frame 2 are tightly connected through the second hexagon socket head cap screws 4. By loosening or tightening the second hexagon socket head cap screws 4, the fixing plate 3 can be disassembled or installed.
[0045] In order to enable the protection plate 7 to perform a buffering movement in the buffering space between the protection plate 7 and the fixing plate 3 relative to the fixing plate 3, the telescopic member includes a sleeve 5 and a sliding rod 6. One end face of the sleeve 5 is fixedly connected to the outer side wall of the fixing plate 3. One end of the sliding rod 6 is inserted into the sleeve 5 and is slidably connected to the sleeve 5. The end face of the sliding rod 6 away from the sleeve 5 is fixedly connected to the side wall of the protection plate 7 facing the fixing plate 3;
[0046] Wherein, one end of the sliding rod 6 located in the inner cavity of the sleeve 5 has a limiting ring. A ring-shaped limiting piece is integrally formed at the top of the sleeve 5. The outer side wall of the limiting ring is slidably connected to the inner wall of the sleeve 5. By sliding the sliding rod 6 in the sleeve 5, the protection plate 7 can perform a buffering movement in the buffering space between the protection plate 7 and the fixing plate 3 relative to the fixing plate 3. Under the action of the limiting ring of the sliding rod 6 and the ring-shaped limiting piece at the top of the sleeve 5, the slipping of the sliding rod 6 can be avoided.
[0047] In order to further optimize the implementation manner of the elastic member, the elastic member is a rubber column 8. One ends of a plurality of rubber columns 8 are fixedly connected to the outer side wall of the fixing plate 3, and the other ends are fixedly connected to the side wall of the protection plate 7 facing the fixing plate 3. The rubber column 8 can effectively absorb the extrusion force, further optimizing the implementation manner of the elastic member. At the same time, when the rubber column 8 resets, the protection plate 7 can be pushed out under the guiding action of the sliding rod 6 and the sleeve 5.
[0048] In order to make the buffering effect of the protection plate 7 more uniform when the protection plate 7 is subjected to an extrusion force, a plurality of rubber columns 8 are evenly distributed at equal intervals in a matrix between the fixing plate 3 and the protection plate 7.
[0049] Summarize and sort out the working steps of this solution according to the above technical solution:
[0050] The fixing frame 2 can not only facilitate installation and disassembly, but also reinforce the polyurethane board 1 from the side of the polyurethane board 1, so that the polyurethane board 1 can withstand a stronger extrusion force. After the fixing plates 3 arranged on both sides of the polyurethane board 1 are installed on the fixing frame 2, the protection plate 7 can be connected through the telescopic member. There is a distance between the protection plate 7 and the fixing plate 3, and this distance is the buffering space in actual application. The protection plate 7 can perform a buffering movement in the buffering space through the telescopic member. At the same time, a plurality of elastic members installed between the protection plate 7 and the fixing plate 3 can effectively absorb the extrusion force received by the protection plate 7, thereby effectively preventing the extrusion of the polyurethane board 1 and enhancing the anti-extrusion ability of the polyurethane board 1;
[0051] Loosen the first hexagon socket head bolt 22, and the fixing frame 2 can be disassembled. Tightening the first hexagon socket head bolt 22 can fasten the fixing frame 2 and the polyurethane board 1;
[0052] By loosening or tightening the second hexagon socket head cap screw 4, the fixing plate 3 can be disassembled or installed;
[0053] By the sliding of the sliding rod 6 in the sleeve 5, the protection plate 7 can be made to perform a buffering movement relative to the fixing plate 3 in the buffering space between the protection plate 7 and the fixing plate 3. Under the action of the limiting ring of the sliding rod 6 and the annular limiting piece at the top of the sleeve 5, the slipping of the sliding rod 6 can be avoided;
[0054] The extrusion force can be effectively absorbed by the rubber column 8, further optimizing the implementation manner of the elastic member. At the same time, when the rubber column 8 resets, the protection plate 7 can be pushed outwards under the guiding action of the sliding rod 6 and the sleeve 5.
[0055] In summary: The fixing frame 2 can not only facilitate installation and disassembly, but also reinforce the polyurethane board 1 from the side of the polyurethane board 1, enabling the polyurethane board 1 to withstand stronger extrusion force.
[0056] After the fixing plates 3 arranged on both sides of the polyurethane board 1 are installed on the fixing frame 2, the protection plate 7 can be connected through the telescopic member. There is a spacing between the protection plate 7 and the fixing plate 3, and this spacing is the buffering space in actual application. The protection plate 7 can perform a buffering movement in the buffering space through the telescopic member. At the same time, a plurality of elastic members installed between the protection plate 7 and the fixing plate 3 can effectively absorb the extrusion force received by the protection plate 7, thereby effectively preventing the extrusion of the polyurethane board 1 and enhancing the anti-extrusion ability of the polyurethane board 1.
