Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, specifically to insulation boards made from waste fibers. Background Technology

[0002] The main raw materials of waste fiber insulation boards include various waste fibers, such as cotton, hemp, polyacrylonitrile fiber, asphalt fiber, viscose fiber, pre-oxidized fiber, phenolic fiber, carbon fiber, graphite fiber, wood fiber and waste glass fiber. After recycling and processing, these waste fibers can be used as reinforcing materials for composite materials and are widely used in construction, transportation, agriculture and other fields.

[0003] Existing insulation boards made from waste glass fiber are commonly used in the construction industry for exterior wall insulation, roof insulation, and floor insulation. Due to their large size, users often use a splicing method, which is usually done by gluing. However, gluing is time-consuming and labor-intensive, affects splicing efficiency, and makes it inconvenient for users to disassemble the insulation boards, thus reducing their practicality.

[0004] For aerogel felt products, low-cost waste inorganic fibers are used as the matrix. The aerogel felt body structure is formed using wet web forming technology, and then in-situ composite of the aerogel with the felt body is achieved using sol-gel integrated molding technology. This allows for controllable preparation of the aerogel felt, clarifying the effects of liquid ratio, aging time, replacement method, and reinforcement parameters on the thermal insulation and mechanical properties of the aerogel felt. The developed aerogel felt can meet the requirements of low thermal conductivity and high thermal insulation properties. Utility Model Content

[0005] The purpose of this invention is to provide an insulation board made from waste fiber, which solves the problem that existing insulation boards made from waste glass fiber are commonly used in the construction industry for exterior wall insulation, roof insulation, and floor insulation. Due to their large area, users mostly use splicing methods, which are often done by gluing. However, gluing is time-consuming and laborious, affects splicing efficiency, and makes it inconvenient for users to disassemble the insulation board, thus reducing its practicality.

[0006] Utilizing the concept of high-value recycling of waste materials, and employing wet web forming and aerogel composite processes, we have developed flexible aerogel insulation materials with high thermal insulation performance. These materials achieve fireproofing, thermal insulation, and other effects. The aerogel felt has a thermal conductivity as low as 0.025 Wm·K and exhibits hydrophobic properties.

[0007] This utility model provides the following technical solution: an insulation board made from waste fiber, including a fixed outer frame, a placement groove on the inner side of the fixed outer frame, a support fixedly connected to the outer side of the fixed outer frame, a snap-fit ​​outer frame rotatably connected to the inner side of the support, a snap-fit ​​groove corresponding to the position of the placement groove on the inner side of the snap-fit ​​outer frame, two symmetrically distributed threaded grooves on the fixed outer frame, bolts threadedly connected to the inner side of the threaded grooves, a glass fiber insulation board snap-fitted to the inner side of the placement groove, and an installation mechanism for splicing the fixed outer frame.

[0008] As a preferred embodiment of the above technical solution, the snap-fit ​​outer frame has two through holes, and two bolts are threaded through the two through holes and connected to the inside of the two threaded grooves. The size of the snap-fit ​​grooves is the same as that of the placement grooves. In use, the user can place the fiberglass insulation board in the placement grooves inside the fixed outer frame, and then rotate the snap-fit ​​outer frame to make it contact the fixed outer frame. Then, the two bolts are passed through the snap-fit ​​outer frame and rotated into the two threaded grooves, thus fixing the fiberglass insulation board. This achieves the effect of convenient installation of the insulation board and also protects the four corners of the insulation board.

[0009] As a preferred embodiment of the above technical solution, the installation mechanism includes two symmetrically distributed positioning rods fixedly connected to one end of the fixed outer frame and a fixed shell fixedly connected to the other end of the fixed outer frame. Both positioning rods have through holes. A rotating shaft is rotatably connected to the bottom inner side of the fixed shell. A gear is fixedly connected to the top of the rotating shaft. A rack meshes with the outer side of the gear. A slider is fixedly connected to the bottom of the rack. A fixed rod is slidably connected to the outer side of the slider. A spring is fixedly connected to the outer side of the slider. A lever is fixedly connected to the side of the rack away from the gear. A rectangular hole is slidably connected to the outer side of the lever. A insertion rod is fixedly connected to the end of the rack away from the spring. Two slots are provided on the fixed shell. In use, the user can move the lever. The movement of the lever drives the right rack to move through the slider and the fixed rod. The movement of the slider compresses the spring, and the movement of the rack drives the gear to rotate. At this time, the left rack is engaged by the gear. The movement of the lever, via another slider and a fixed rod, causes the two racks to move, which in turn moves the two insert rods. These insert rods then move from their slots into the fixed housing. The user can then insert the positioning rod on the outer side of the fixed outer frame, which contains the fiberglass insulation board, into the two slots on the fixed housing. After releasing the lever, the racks return to their original positions under the influence of the spring. The two insert rods on the racks then pass through the fixed housing and insert into the perforations on the positioning rods in the two slots, completing the installation of the two fiberglass insulation boards. For disassembly, the user can move the lever again. Similarly, after the insert rods separate from the positioning rods, the user can disassemble the two fixed outer frames, thus facilitating the splicing of the insulation boards and the removal of the insulation boards.

[0010] As a preferred embodiment of the above technical solution, the perforations on the two positioning rods are staggered, and the positions of the two positioning rods correspond to the two slots, and the dimensions of the two positioning rods are adapted to the two slots.

[0011] As a preferred embodiment of the above technical solution, the bottom of the rotating shaft is rotatably connected to the inner bottom of the fixed shell through a bearing seat. There are two racks, both of which mesh with the gear. The two racks are distributed on both sides of the gear and are the same size. There are two insert rods, which are fixedly connected to the two outer ends of the two racks respectively. The two insert rods are staggered and their positions correspond to the two through holes. The two insert rods pass through the fixed shell and are inserted into the inner side of the two slots.

[0012] As a preferred embodiment of the above technical solution, there are two sliders, two springs, and two fixed rods. The two sliders are fixedly connected to the bottom of the two racks respectively, and the two sliders are slidably connected to the two fixed rods respectively. The two fixed rods are fixedly connected to the inner side of the fixed shell. One end of the two springs is fixedly connected to the outer side of the two sliders respectively, and the other end of the two springs is fixedly connected to the inner side of the fixed shell. The two springs are distributed on the outer side of the two fixed rods respectively. The rectangular hole is opened on the outer side of the fixed shell, and the lever is fixedly connected to the outer side of the right rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model includes a fixed outer frame, a placement groove, a support, a snap-fit ​​outer frame, a snap-fit ​​groove, a threaded groove, bolts, a fiberglass insulation board, and an installation mechanism. In use, the user places the fiberglass insulation board in the placement groove inside the fixed outer frame, then rotates the snap-fit ​​outer frame until it contacts the fixed outer frame. Next, two bolts are passed through the snap-fit ​​outer frame and rotated into the two threaded grooves, thus securing the fiberglass insulation board. When splicing the fiberglass insulation boards, the user can move a lever. The lever's movement drives the right rack through a slider and a fixed rod. The slider's movement compresses a spring, causing the rack to rotate a gear. Simultaneously, the left rack is driven by the gear through another slider and a fixed rod. The movement of both racks... The two insert rods move from their slots into the fixed housing. The user can then insert the positioning rod on the outer side of the fixed frame containing the fiberglass insulation board into the two slots on the fixed housing. Releasing the lever causes the rack to return to its original position under spring pressure. The two racks then return to their original positions, and the two insert rods on them pass through the fixed housing and into the holes on the positioning rods. This completes the installation of the two fiberglass insulation boards, facilitating easy fixing and disassembly, thus improving practicality. It also protects the four corners of the insulation boards, extending their lifespan, and makes it easier for users to assemble and install the insulation boards, further enhancing usability.
