Description

Technical Field

[0001] The utility model relates to the technical field of wave-absorbing materials, in particular to a wave-absorbing material cover plate. Background Art

[0002] Absorbing materials are a special type of functional materials that can reduce the reflection of electromagnetic waves, thereby weakening or eliminating unwanted electromagnetic interference (EMI). When electromagnetic waves enter the absorbing material, the specific structure or composition inside the material will convert the energy of these waves into other forms of energy, usually heat energy, thereby achieving the absorption effect.

[0003] Hard closed-cell polystyrene and polypropylene absorbing materials are becoming increasingly popular in the market due to their advantages such as no powdering, no moisture absorption, no sagging, and long service life. In order to optimize the absorption effect of electromagnetic waves, the top of the absorbing material usually adopts a cone-shaped design; therefore, a cover is needed to protect the tip of the absorbing material to prevent damage to the absorbing material. Since the protective cover of the absorbing material mostly adopts an integrated design, its limit spacing cannot be accurately adjusted. The absorbing material will be designed into different sizes according to usage requirements, so when using the cover, it is impossible to protect absorbing materials of different sizes.

[0004] Therefore, it is necessary to design an adjustable absorbing material cover. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: A cover plate made of absorbing material, see Figure 1-Figure 4 As shown, it includes a cover plate 1, a guide rail 2, a slider 3, a buffer structure, a limit block 5 and a V-shaped plate 6. The guide rail 2 is installed on the rear side of the bottom of the cover plate 1 by bolt connection. Four sliders 3 are slidably arranged in the guide rail 2. A buffer structure is provided at the lower part of the slider 3. A limit block 5 is provided on the buffer structure. The buffer structure is used to buffer between the limit block 5 and the guide rail 2. The limit block 5 is slidably arranged away from the lower part of the cover plate 1 with a V-shaped plate 6. The V-shaped plate 6 can span the sharp cones of multiple continuous absorbing materials. A scale 26 is provided on the right side of the bottom of the guide rail 2. The scale 26 is used to facilitate precise adjustment of the position of the V-shaped plate 6. A mounting plate 7 is installed on the other side of the bottom of the cover plate 1. A limit slot 4 is provided on the side of the guide rail 2 close to the mounting plate 7. A slide plate 8 is slidably arranged on the mounting plate 7. Four Slide groove 9, four slide grooves 9 are distributed on the left and right sides of the top of the skateboard 8, and the slide grooves 9 on both sides of the top of the skateboard 8 are symmetrically arranged, a connecting block 10 is fixed to the top of the skateboard 8, and two mounting seats 11 are installed on the top of the mounting plate 7, a screw 12 is rotatably arranged between the two mounting seats 11, the connecting block 10 is threadedly connected to the screw 12, two first guide rods 13 are fixed to the mounting plate 7, and four connecting rods 14 are slidingly arranged on the two first guide rods 13, the connecting rod 14 passes through the limit groove 4 and is connected to the slider 3, a guide block 15 is installed on the top of the connecting rod 14, the guide block 15 slides in the corresponding slide groove 9, and the guide blocks 15 on both sides of the skateboard 8 respectively drive the connecting rod 14 to slide to both sides, the cover plate 1, the guide rail 2, the limit block 5 and the V-shaped plate 6 are all made of polystyrene granular material by injection molding.

[0025] See Figure 5 As shown, the buffer structure includes a buffer material 16, a slide rod 17 and a first elastic member 1701. A guide groove is provided at the bottom of the slider 3. The slide rod 17 is slidably arranged in the guide groove. The buffer material 16 is placed in the guide groove. The outside of the buffer material 16 is made of rubber air bag, and the inside of the air bag is filled with air. The lower end of the slide rod 17 is connected to the limit block 5. The first elastic member 1701 is connected between the limit block 5 and the slider 3. The first elastic member 1701 is sleeved on the slide rod 17.

[0026] When it is necessary to protect the absorbing material, the screw 12 is rotated, and the screw 12 drives the connecting block 10 to slide back and forth, and the connecting block 10 drives the slide plate 8 to slide back and forth. When the slide plate 8 slides back and forth, the slide groove 9 squeezes the guide block 15 to drive the connecting rod 14 to slide on the first guide rod 13, and the connecting rod 14 drives the slider 3 to slide on the guide rail 2. The slider 3 drives the V-shaped plate 6 to slide left and right through the slide rod 17 and the limit block 5, thereby quickly adjusting the distance between the four V-shaped plates 6, so that the V-shaped plate 6 can cover the top of the absorbing material of different sizes, thereby achieving the purpose of protecting the absorbing materials of different sizes, and then the cover plate 1 is closed. The V-shaped plate 6 is covered on the absorbing material to cover the top of the absorbing material. When the absorbing material is impacted from the vertical direction, the V-shaped plate 6 squeezes the limit block 5 to move upward, and the limit block 5 squeezes the first elastic member 1701 to deform. The limit block 5 drives the slide bar 17 to slide up and down in the guide groove. The slide bar 17 squeezes the buffer material 16 and deforms under force, thereby buffering the impact force on the absorbing material from the vertical direction and preventing the absorbing material from being damaged by the impact. When the vertical impact disappears, the buffer material 16 and the first elastic member 1701 return to their original state, driving the slide bar 17, the limit block 5 and the V-shaped plate 6 to slide downward and reset.

[0027] Example 2: Based on Example 1, refer to Figure 6 and Figure 7 As shown, it also includes a second guide rod 18, a clamping plate 19, a connecting plate 20 and a second elastic member 21. Four second guide rods 18 are slidably provided on both sides of the left and right sides of the V-shaped plate 6. The four second guide rods 18 are located at one end inside the V-shaped plate 6 and are commonly connected to the clamping plate 19. The cross-section of the two clamping plates 19 is in an eight-shaped shape, so that the clamping plate 19 can maintain a consistent orientation with the sharp cone of the absorbing material, thereby facilitating the clamping of the sharp cone of the absorbing material and preventing the edge of the clamping plate 19 from crushing the absorbing material. The four second guide rods 18 are located at one end outside the V-shaped plate 6 and are commonly connected to the connecting plate 20. Four second elastic members 21 are connected between the clamping plate 19 and the V-shaped plate 6. The second elastic member 21 is sleeved on the second guide rod 18.

[0028] See Figure 6 and Figure 7 As shown, it also includes a contact plate 22, a connecting seat 24 and a push block 25. The contact plate 22 is fixedly connected to the top of the connecting plate 20. A straight groove 23 is provided on the front side of the upper part of the V-shaped plate 6. The connecting seat 24 is slidably provided in the straight groove 23. Push blocks 25 are fixedly connected on both sides of the connecting seat 24. The push blocks 25 are in contact with the adjacent contact plates 22. The contact surface between the contact plate 22 and the push block 25 is an inclined surface. The push block 25 can squeeze the contact plate 22 to move outward.

[0029] The push block 25 drives the connecting seat 24 to slide forward and reset along the slot 23, so that the clamping plate 19 clamps the two sides of the sharp cone of the absorbing material, thereby preventing the V-shaped plate 6 and the top of the sharp cone of the absorbing material from being separated when the cover 1 is hit.
