Description

Technical Field

[0001] This utility model relates to the field of foam board technology, and in particular to an anti-collision foam board. Background Technology

[0002] In the field of foam board technology, foam boards are widely used in packaging, building protection, logistics and transportation due to their lightweight and good cushioning properties, in order to reduce damage to objects during collisions.

[0003] However, existing foam boards have certain shortcomings in their impact-resistant structural design. Most foam boards are made of a single-structure foam material, which is prone to deformation or even breakage when subjected to a large impact, making it difficult to provide continuous and effective impact protection. Some composite foam boards have simple connection methods between their components, which can easily lead to delamination and detachment after long-term use or repeated collisions, affecting the impact-resistant effect. Furthermore, the buffer structure design of traditional foam boards is relatively simple, relying solely on the elasticity of the foam itself for buffering. When subjected to a strong instantaneous impact, the buffering energy absorption effect is poor, and it cannot effectively reduce the impact of the collision on the object. Therefore, this application proposes an impact-resistant foam board. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shock-absorbing foam board to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing foam board, comprising:

[0006] The inner panel has two sets that are symmetrically attached front and back, and each set of inner panels has four aligned openings at the four corners of its sides.

[0007] The space frame is provided in two sets, which are respectively attached to the front and rear sides of the inner panel, and there are docking components located in the corresponding openings between the four corners of the two sets of space frames.

[0008] The first outer plate covers the inner plate and the front mesh frame, and the first screw groove is provided at each of the four corners of the side of the first outer plate.

[0009] The second outer panel covers the inner panel and the rear grid frame, and the four corners of the side of the second outer panel are provided with second screw grooves.

[0010] The connecting component is inserted between the first and second threaded grooves at the corresponding positions, and the connecting component is inserted through the corresponding mating components.

[0011] Furthermore, the docking assembly includes a first ring and a second ring. The first ring is fixedly installed at the corner of the rear mesh frame, and the second ring is fixedly installed at the corner of the front mesh frame. Both the first and second rings are inserted into the corresponding openings on the side of the inner plate. The outer side of the first ring away from the mesh frame has an outer ring groove, and four limiting plugs are arranged in a circular array inside the outer ring groove. The inner side of the second ring away from the mesh frame has an inner ring groove, and four limiting grooves are arranged in a ring array on the inner wall of the inner ring groove. The outer ring groove end of the first ring can be inserted into the inner ring groove of the second ring, and the four sets of limiting plugs can be respectively engaged in the corresponding limiting grooves.

[0012] Furthermore, the limiting plug includes a limiting block, a push rod, and a first spring. A groove is provided on the outer side of the outer ring groove, and the limiting block is movably inserted into the groove. A through hole communicating with the inside of the first collar is provided at the inner end of the groove. The push rod is fixedly connected to the limiting block, and the end of the push rod away from the limiting block is inserted into the through hole. The first spring is sleeved on the push rod, and the two ends of the first spring are respectively fixedly connected to the inner end of the groove and the limiting block. When the end of the limiting block extending out of the groove is engaged in the limiting groove on the inner wall of the inner ring groove, the end of the push rod away from the limiting block is flush with the inner wall of the first collar.

[0013] Furthermore, the connecting assembly includes a bolt, a nut, and a locking insert. The bolt is inserted through and into a first threaded groove on the first outer plate, and the bolt passes through the corresponding connecting assembly and extends to the second outer plate. The nut is threaded onto the bolt and located in the second threaded groove. The bolt has a slot at its end and a first notch on both sides of its end. The nut has two second notches on its side that correspond to the positions of the first notches. The locking insert is inserted into the slot at the bolt end and engages with the corresponding first and second notches.

[0014] Furthermore, the locking plug includes a connecting plate, a plug rod, a connecting rod, and a second spring. One end of the plug rod has a threaded groove, and a screw is fixedly installed in the slot. The threaded groove at one end of the plug rod is threaded onto the screw. The other end of the plug rod has a connecting groove. The connecting rod is set in the shape of a square column and is movably inserted into the connecting groove. The connecting plate is fixedly installed at the end of the connecting rod located outside the connecting groove, and the two ends of the connecting plate are respectively engaged in the corresponding first notch and second notch. The second spring is sleeved on the outside of the connecting rod, and the two ends of the second spring are connected to the connecting plate and the plug rod. An unlocking screw groove is provided on the side of the connecting plate away from the connecting rod.

[0015] Furthermore, both inner panels have inner grooves on their mating sides, and neatly arranged arc-shaped plates are fixedly installed in the inner grooves on both sides of the inner panels. When the two inner panels are joined together, the arc-shaped plates in the inner grooves on their sides are staggered and mated together.

[0016] Furthermore, a sealing groove is provided on the side of the first outer plate mating end, and a sealing plate adapted to the sealing groove is fixedly installed on the side of the second outer plate mating end. When the second outer plate and the first outer plate are mated, the sealing plate is fitted into the sealing groove.

[0017] The beneficial effects of this utility model are:

[0018] It adopts a composite structure of double inner panels, double space frame and double outer panels. The inner panels provide basic cushioning, the outer space frame is enhanced with metal or high-strength materials to enhance tensile and deformation resistance. The first and second outer panels form a rigid protective shell. The multi-layer structure works together to resist impact force, which solves the problem of easy breakage of traditional single foam board. The two sets of inner panels are set with staggered arc plates on the bonding surface. When there is a collision, the arc plates disperse stress through deformation, further improving the cushioning and energy absorption effect, and effectively cope with instantaneous strong impact force.

[0019] At the corners, the structure is double-fixed using a combination of docking components (first and second rings) and connecting components (bolts, nuts, and locking inserts). The docking components pre-fix the space frame and inner plate by engaging the limiting inserts with the limiting grooves. The connecting components use bolts that penetrate the inner and outer plates and are locked in place with nuts. The locking inserts further prevent the bolts and nuts from loosening, avoiding delamination and detachment after long-term use or repeated collisions. Both the limiting inserts and the locking inserts use spring structures to provide elastic pre-tightening force during assembly, ensuring that the connecting parts fit tightly and improving the overall stability of the structure.

[0037] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0038] Please see Figures 1-9This utility model provides a technical solution: a shock-absorbing foam board, including an inner board 1, with two sets of inner boards 1 symmetrically attached front and back. Each of the four corners of the sides of the two sets of inner boards 1 has aligned openings 11. A mesh frame 2 is attached to the outer sides of both sets of inner boards 1, and a connecting component located within the corresponding opening 11 is provided between the four corners of the two sets of mesh frames 2. A first outer board 31 is fitted over the inner board 1 and the front mesh frame 2, with a first screw groove 32 provided at each of the four corners of the side of the first outer board 31. A second outer board 33 is fitted over the inner board 1 and the rear mesh frame 2, with a first screw groove 32 provided at each of the four corners of the side of the second outer board 33. A second screw groove 34 is provided, and a connecting component 35 is inserted between the corresponding first screw groove 32 and second screw groove 34. The connecting component 35 is inserted through the corresponding mating components. Through the multi-layer composite structure design, the coordinated fixation between components is achieved: the inner plate 1 provides basic buffer, the grid frame 2 enhances the structural strength, the first outer plate 31 and the second outer plate 33 form external protection, and the connecting component 35 penetrates through each layer to achieve overall locking. Compared with traditional single-structure foam boards, its advantage lies in improving the overall impact resistance through layered design, while solving the problem of loose connection in traditional composite boards, ensuring structural stability during long-term use.

[0039] like Figure 2 and Figure 3 As shown, the docking assembly includes a first ring 21 and a second ring 22. The first ring 21 is fixedly installed at the corner of the rear mesh frame 2, and the second ring 22 is fixedly installed at the corner of the front mesh frame 2. Both the first ring 21 and the second ring 22 are inserted into the corresponding openings 11 on the side of the inner plate 1. The outer side of the end of the first ring 21 away from the mesh frame 2 has an outer ring groove 211, and four limiting plugs 212 are arranged in a circular array inside the outer ring groove 211. The inner side of the end of the second ring 22 away from the mesh frame 2 has an inner ring groove 221, and four limiting plugs 212 are arranged in a circular array on the inner wall of the inner ring groove 221. The outer ring groove 211 end of the first set of rings 21 can be inserted into the inner ring groove 221 of the second set of rings 22, and the four sets of limiting plugs 212 can be respectively engaged in the corresponding limiting grooves 222. The first set of rings 21 and the second set of rings 22, through the nesting structure of the outer ring groove 211 and the inner ring groove 221, together with the engagement of the limiting plugs 212 and the limiting grooves 222, achieve precise docking and pre-fixation between the front and rear side space frame 2 and the inner plate 1. The engagement structure of the limiting plugs 212 and the limiting grooves 222 enhances the tightness of the connection between the space frame 2 and the inner plate 1, prevents relative displacement during collision, and solves the problem of delamination and detachment of traditional composite panels.

[0040] like Figure 6As shown, the limiting plug 212 includes a limiting block, a push rod, and a first spring. A groove is formed on the outer side of the outer annular groove 211, and the limiting block is movably inserted into the groove. A through hole communicating with the inside of the first collar 21 is formed at the inner end of the groove. The push rod is fixedly connected to the limiting block, and the end of the push rod away from the limiting block is inserted into the through hole. The first spring is sleeved on the push rod, and both ends of the first spring are fixedly connected to the inner end of the groove and the limiting block, respectively. When the end of the limiting block extending out of the groove engages with the limiting groove 222 on the inner wall of the inner annular groove 221, the end of the push rod away from the limiting block is flush with the inner wall of the first collar 21, and the first spring lifts... Provides continuous preload to ensure that the limiting block is stably engaged in the limiting groove 222, improving connection reliability. The top rod is designed to be pushed during the installation of the connecting component 35, realizing the adaptive adjustment of the limiting plug 212. This facilitates assembly without affecting the through-fixation of the connecting component 35, balancing connection strength and assembly convenience. Furthermore, when the bolt 351 in the connecting component 35 is inserted between the first collar 21 and the second collar 22, the bolt 351 can push against the top rod so that the limiting block at its end can be stably engaged in the limiting groove 222, thereby increasing the stability of the connection between the first collar 21 and the second collar 22.

[0041] like Figure 7 , Figure 8 and Figure 9 As shown, the connecting assembly 35 includes a bolt 351, a nut 352, and a locking insert 353. The bolt 351 is inserted through and into the first threaded groove 32 on the first outer plate 31, and the bolt 351 passes through the corresponding connecting assembly 35 and extends to the second outer plate 33. The nut 352 is threaded onto the bolt 351 and located in the second threaded groove 34. The end of the bolt 351 has a slot 3511, and both sides of the end of the bolt 351 have first notches 3512. The side of the nut 352 has two notches 3512 that correspond to the first notches 3511. The second notch 3521 corresponding to position 512 is into which the locking plug 353 is inserted and engaged in the slot 3511 at the end of the bolt 351 and the corresponding first notch 3512 and second notch 3521. The threaded connection between the bolt 351 and the nut 352 achieves rigid locking between the first outer plate 31, the second outer plate 33 and the internal structure. The locking plug 353 prevents the bolt 351 and the nut 352 from loosening by engaging the first notch 3512 and the second notch 3521, thus solving the problem of traditional fasteners being prone to falling off after long-term use.

[0042] like Figure 8 and Figure 9As shown, the locking plug 353 includes a connecting plate 3531, a plug rod 3532, a connecting rod 3533, and a second spring 3534. One end of the plug rod 3532 has a threaded groove 3535, and a screw 3513 is fixedly installed in the slot 3511. The threaded groove 3535 at one end of the plug rod 3532 is threaded onto the screw 3513. The other end of the plug rod 3532 has a connecting groove. The connecting rod 3533 is shaped like a square column and is movably inserted into the connecting groove. The connecting plate 3531 is fixedly installed at the end of the connecting rod 3533 located outside the connecting groove, and the two ends of the connecting plate 3531 are respectively engaged in the corresponding first notch 3512 and second notch 3521. The second spring 3534 is sleeved on the outside of the connecting rod 3533, and the two ends of the second spring 3534 are connected to the connecting plate 3531. On the insert rod 3532, an unlocking screw groove is provided on the side of the connecting plate 3531 away from the connecting rod 3533. The threaded connection between the insert rod 3532 and the screw 3513 can realize the fixation of the locking insert 353. The elasticity of the second spring 3534 ensures that the connecting plate 3531 is tightly engaged in the first notch 3512 and the second notch 3521, further enhancing the anti-loosening effect. The connecting plate 3531 can drive the insert rod 3532 to rotate together through the square column-shaped connecting rod 3533, which can realize the connection and separation of the insert rod 3532 and the screw 3513, solving the problem that traditional fixing structures are difficult to disassemble. By using a tool to connect to the unlocking screw groove on the side of the connecting plate 3531 and pull it outward, the connecting plate 3531 can be separated from the first notch 3512 and the second notch 3521 and rotated to unlock.

[0043] like Figure 5 As shown, the two inner panels 1 have inner grooves on their mating sides. In the inner grooves on the sides of the two inner panels 1, neatly arranged arc-shaped plates 12 are fixedly installed. When the two inner panels 1 are joined, the arc-shaped plates 12 in their side inner grooves are staggered and mated together. When they collide, the arc-shaped plates 12 disperse the impact force by mutual compression and deformation, forming a multi-level buffer. Compared with the traditional single foam buffer structure, the energy absorption effect is more significant and can effectively cope with instantaneous strong impact. The staggered distribution design increases the contact area and improves the tightness of the mating of the inner panels 1, avoiding buffer failure caused by gaps during the buffering process.

[0044] like Figure 4 As shown, a sealing groove 311 is provided on the side of the first outer plate 31 at the mating end, and a sealing plate 331 adapted to the sealing groove 311 is fixedly installed on the side of the second outer plate 33 at the mating end. When the second outer plate 33 is mated with the first outer plate 31, the sealing plate 331 is fitted into the sealing groove 311. By applying glue into the sealing groove 311 and fitting it in, the stability of the mating between the first outer plate 31 and the second outer plate 33 can be further improved.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
