Description

Technical Field

[0001] The utility model relates to the technical field of foam plastic plates, and more specifically, it relates to a fluorine-free modified polyisocyanurate foam plastic plate. Background Art

[0002] Polyisocyanurate foam plastics are formed by the self-trimerization reaction of isocyanates to produce isocyanate rings. From the perspective of molecular structure, polyisocyanurate foam plastics are more stable. The fluorine-free modified isocyanurate foam plastic plate has better heat resistance, cold resistance and flame retardancy.

[0003] At present, the structure of the fluorine-free modified polyisocyanurate foam plastic plates on the market is single. When in use, they need to be spliced by gluing, and the connection stability is low. When the polyisocyanurate foam plastic plates are used for heat preservation, the glue viscosity is likely to decrease due to long-term heating of the plates, resulting in the detachment of the plates. Moreover, the foam plastic plates are prone to deformation or fracture after bearing weight, affecting their use effect and shortening their service life. Summary of the Utility Model

The two convex blocks are fixedly connected to both ends of the top of the plate body. The positioning block is placed between the two convex blocks and fixed to the center of the top of the plate body. Each of the two convex blocks is provided with a first through hole for the insertion rod to pass through. Installation holes are provided at both ends of the positioning block. The two rubber sleeves are respectively fixed in the installation holes. One end of the insertion rod can extend into the rubber sleeve and be clamped with the rubber sleeve.

[0007] Further set as, the strengthening component includes a strengthening plate, a clamping block and a spring. An embedding groove is formed on the plate body. The strengthening plate can be placed in the embedding groove. An installation groove is formed on the strengthening plate. The spring is fixed in the installation groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Refer to Figures 1 to 4 to further illustrate the embodiments of the present utility model.

[0019] A fluorine-free modified polyisocyanurate foam plastic plate includes a plate body 1, the plate body 1 is made of fluorine-free modified polyisocyanurate material, an embedding groove 11 is formed on the plate body 1, and a positioning groove 12 is provided in the embedding groove 11.

[0020] The plate body 1 is provided with a strengthening component. The strengthening component includes a reinforcing plate 6, a clamping block 7 and a spring 8. An installation groove 61 is formed in the reinforcing plate 6. The bottom of the spring 8 is fixed in the installation groove 61. The bottom of the clamping block 7 is fixedly connected to the top of the spring 8. The clamping block 7 can be clamped in the positioning groove 12. The reinforcing plate 6 is pushed into the embedding groove 11, the spring 8 is compressed, and the clamping block 7 is pressed into the installation groove 61. When the reinforcing plate 6 is pushed to the end in the embedding groove 11, the clamping block 7 corresponds to the positioning groove 12, and the spring 8 resumes its elastic length so that the clamping block 7 is clamped into the positioning groove 12. At the same time, a limiting piece 9 fixed to the other end of the reinforcing plate 6 abuts against the bottom of the plate body 1. The reinforcing plate 6 is made of a metal material with a relatively high hardness, has high strength and is not easily deformed, effectively improving the load-bearing capacity and stability of the foam plastic plate.

[0021] A connecting component is provided at the top end of the plate body 1. The connecting component includes two convex blocks 2, a positioning block 3, two rubber sleeves 4 and two insertion rods 5. The two convex blocks 2 are both fixedly connected to the two ends of the top of the plate body 1. A first through hole 21 for the insertion rod 5 to pass through is provided on each of the two convex blocks 2. The positioning block 3 is located between the two convex blocks 2 and is fixed to the center of the top of the plate body 1. Installation holes 31 are provided on both sides of the positioning block 3. The two rubber sleeves 4 are respectively fixed in the installation holes 31 on both sides. One end of the insertion rod 5 can extend into the rubber sleeve 4 and be clamped with the rubber sleeve 4.

[0022] Two connecting blocks 10 are provided at the bottom end of the plate body 1 of the plate. Second through holes 101 for the insertion rod 5 to pass through are provided on the connecting blocks 10. The space between the two convex blocks 2 and the positioning block 3 forms two insertion places for the two connecting blocks 10 to be inserted. When two plates are spliced up and down, the connecting block 10 at the bottom of the upper plate is inserted into the insertion place between the two convex blocks 2 and the positioning block 3. Then the two insertion rods 5 are respectively inserted into the first through holes 21 of the convex blocks 2 on the left and right sides. The extending end of the insertion rod 5 sequentially passes through the first through hole 21 of the convex block 2 and the second through hole 101 of the connecting block 10, and extends into the rubber sleeve 4 until it abuts against the end of the installation hole 31. Since the rubber sleeve 4 has a certain elasticity, the two insertion rods 5 can be respectively locked in the installation holes 31 on both sides of the positioning block 3, so that the two plates are spliced and connected together.

[0023] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
