Abstract
Description
Technical Field
[0001] This utility model relates to the field of microwave absorbing materials technology, specifically to an assembly structure of a hollow pyramidal skeleton. Background Technology
[0002] In order to make electromagnetic wave absorbing materials have good absorption performance at low frequencies, the absorbing materials are often made very tall. However, for polyurethane absorbing materials with a height of more than 1 meter, due to the soft texture of polyurethane foam absorbing materials, a drooping point will appear when the height exceeds 1 meter. Therefore, absorbing materials with a height of more than 1 meter are usually made into a hollow pyramid shape, with polystyrene board as the skeleton inside and polyurethane foam absorbing sheet wrapped on the outside.
[0003] Existing hollow pyramid skeletons are generally made by gluing four plates together to form a four-sided pyramid structure. The gluing process has low production efficiency and requires additional adhesives for bonding.
[0004] To address the above problems, this utility model provides an assembly structure for a hollow pyramidal skeleton. Utility Model Content
[0005] The purpose of this utility model is to provide an assembly structure for a hollow pyramid skeleton. The hollow pyramid skeleton adopts a snap-fit process, which does not use adhesives, simplifies the process, improves production efficiency, and thus solves the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for a hollow pyramid skeleton, comprising a base, four evenly distributed first slots on the upper surface of the base, a rectangular groove on the outer side of the base, a rod inserted into the rectangular groove, a spring sleeved on the outer side of the rod, two symmetrical first polystyrene plates on the upper end of the base, two symmetrical second polystyrene plates between the two first polystyrene plates, several evenly distributed second slots symmetrically distributed on both sides of the inner side of the first polystyrene plates, several evenly distributed second locking blocks symmetrically fixed on both sides of the second polystyrene plates, and a first locking block fixed at the center of the bottom end of both the first and second polystyrene plates.
[0007] Furthermore, the second card block and the second card slot correspond one-to-one, and the inner sides of the second card block and the second card slot engage with each other.
[0008] Furthermore, the first card block and the first card slot correspond one-to-one, and the inner sides of the first card block and the first card slot engage with each other.
[0009] Furthermore, the rectangular groove is located on one side of the first slot, and a sliding plate is fixed at the end of the insertion rod. The insertion rod is slidably connected to the inner wall of the rectangular groove, and the sliding plate is slidably connected to the inner surface of the rectangular groove. A spring is fastened between the side of the sliding plate and the inner wall of the rectangular groove. An insertion hole is opened inside the first block. The spring drives the end of the insertion rod away from the sliding plate to enter the first slot and insert into the insertion hole.
[0010] Furthermore, the outer surface of the skateboard is textured with anti-slip patterns.
[0011] Furthermore, polyurethane foam absorbing sheets are attached and fixed to the outer surfaces of both the first and second polystyrene boards.

[0013] This utility model provides an assembly structure for a hollow pyramid skeleton. First, take one first polystyrene board, then two second polystyrene boards. Insert the second locking blocks on the same side of the two second polystyrene boards into their corresponding second locking slots. Then, take another first polystyrene board, and insert the second locking blocks on the other side of the two second polystyrene boards into their corresponding second locking slots, thus splicing the four boards together to form a hollow pyramid skeleton. Next, manually move the insert rod in a straight line away from the first locking slot while stretching the spring. Then, insert the four first locking blocks at the bottom of the hollow pyramid skeleton into the four first locking slots at the top of the base and release the spring. Under the spring's restoring deformation, the insert rod moves in the opposite direction to reset and its end is inserted into the first locking block in the first locking slot. At this point, the hollow pyramid skeleton is assembled. The purpose of this design is to use a snap-fit process for the hollow pyramid skeleton, eliminating the need for adhesives, simplifying the process, and improving production efficiency.

[0021] An assembly structure for a hollow pyramidal skeleton includes a base 1. The upper surface of the base 1 has four evenly distributed first slots 2. A rectangular groove 9 is formed on the outer side of the base 1, and a rod 11 is installed within the rectangular groove 9. A spring 12 is sleeved on the outer side of the rod 11. Two symmetrical first polystyrene plates 3 are positioned at the upper end of the base 1. Two symmetrical second polystyrene plates 5 are positioned between the two first polystyrene plates 3. Several evenly distributed second slots 4 are symmetrically formed on both sides of the inner surface of the first polystyrene plates 3. Several evenly distributed second locking blocks 6 are symmetrically fixed on both sides of the second polystyrene plates 5 near the first polystyrene plates 3. First locking blocks 8 are fixed at the center of the bottom end of both the first and second polystyrene plates 3.
[0022] Specifically, first take one first polystyrene board 3, then take two second polystyrene boards 5, and insert the second locking blocks 6 on the same side of the two second polystyrene boards 5 into the corresponding second locking slots 4. Then take another first polystyrene board 3, and insert the second locking blocks 6 on the other side of the two second polystyrene boards 5 into the corresponding second locking slots 4, so that the four boards are spliced together to form a hollow pyramid skeleton. Then manually move the insertion rod 11 in a straight line away from the first locking slot 2 and stretch the spring 12. Then insert the four first locking blocks 8 at the bottom of the hollow pyramid skeleton into the four upper parts of the base 1.
[0023] The spring 12 is released and inserted into the first slot 2. As the spring 12 recovers its deformation, the insertion rod 11 moves in the opposite direction to reset and its end is inserted into the first locking block 8 within the first slot 2. At this point, the hollow pyramid frame is assembled. The purpose of this design is to use a snap-fit process for the hollow pyramid frame, eliminating the need for adhesives, simplifying the process, and improving production efficiency.
[0024] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:
[0025] The second locking block 6 corresponds to the second locking slot 4 one by one, and the inner sides of the second locking block 6 and the second locking slot 4 engage with each other. The purpose of this design is to allow the first polystyrene board 3 and the second polystyrene board 5 to be spliced together to form a hollow pyramid skeleton by engaging the second locking block 6 and the second locking slot 4.
[0026] Furthermore, such as Figure 1-3 As shown, the following preferred technical solutions are provided:
[0027] The first locking block 8 corresponds to the first locking slot 2 one by one, and the inner sides of the first locking block 8 and the first locking slot 2 engage with each other. The purpose of this design is to enable the hollow pyramid frame and the base 1 to be installed together by engaging the first locking block 8 and the first locking slot 2.
[0028] Furthermore, such as Figure 1-4 As shown, the following preferred technical solutions are provided:
[0029] The rectangular groove 9 is located on one side of the first slot 2. The end of the insertion rod 11 is fixedly provided with a sliding plate 10. The insertion rod 11 is slidably connected to the inner wall of the rectangular groove 9, and the sliding plate 10 is slidably connected to the inner surface of the rectangular groove 9. The spring 12 is fastened between the side of the sliding plate 10 and the inner wall of the rectangular groove 9. The first block 8 has an insertion hole 13 inside. The spring 12 drives the end of the insertion rod 11 away from the sliding plate 10 to enter the first slot 2 and insert into the insertion hole 13. The purpose of this design is to fix the position of the first block 8 by driving the insertion rod 11 into the insertion hole 13 through the spring 12.
[0030] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0031] The outer surface of the skateboard 10 is textured with anti-slip patterns, which is designed to facilitate manual movement of the skateboard 10.

[0033] Both the outer surfaces of the first polystyrene board 3 and the second polystyrene board 5 are covered with polyurethane foam absorbing sheets 7. The purpose of this design is to wrap the polyurethane foam absorbing sheets 7.
[0034] In summary: First, take one first polystyrene board 3, then take two second polystyrene boards 5. Insert the second locking blocks 6 on the same side of the two second polystyrene boards 5 into the corresponding second locking slots 4. Then take another first polystyrene board 3, and insert the second locking blocks 6 on the other side of the two second polystyrene boards 5 into the corresponding second locking slots 4, so that the four boards are spliced together to form a hollow pyramid skeleton. Next, manually move the insert rod 11 in a straight line away from the first locking slot 2 and stretch the spring 12. Then, insert the four first locking blocks 8 at the bottom of the hollow pyramid skeleton into the four first locking slots 2 at the top of the base 1 and release the spring 12. Under the pull of the spring 12 returning to its original deformation, the insert rod 11 moves in the opposite direction to reset and its end is inserted into the first locking blocks 8 in the first locking slots 2. At this time, the hollow pyramid skeleton is assembled. The purpose of this design is to use a snap-fit process for the hollow pyramid skeleton, without the use of adhesives, which simplifies the process and improves production efficiency.
