Description

Technical Field

[0001] The utility model relates to the technical field of rubber, in particular to a rubber structure with flame retardant function. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (Tg). Its molecular weight is often large, greater than hundreds of thousands. Rubber is divided into natural rubber and synthetic rubber. Natural rubber is processed from gum extracted from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or various aspects of life.

[0003] Some existing rubbers are not provided with flame retardant structures during manufacturing. Thus, in some specific environments, such as in some electric control cabinets, when an open flame occurs, the general effect function is relatively simple and the safety performance is low. Utility Model Content

In some specific environments, such as in some electrical control cabinets, when an open flame occurs, the general effect function is relatively single and the safety performance is low.

[0005] Based on the above purpose, the utility model provides a rubber structure with flame retardant function, including a rubber body, characterized in that liquid cavities are provided on both sides of the interior of the rubber body, the interior of the liquid cavity is filled with liquid, a slide groove is provided on the interior of the rubber body, blocks are slidably connected on both sides of the interior of the slide groove, memory metal is fixedly connected to the opposite sides of the two blocks, connecting rods are fixedly connected to the backs of the two blocks, a push plate is fixedly connected to one side of the connecting rod, cavities connected to the slide grooves are provided at upper and lower positions on both sides of the interior of the rubber body, connecting cavities are provided on the upper and lower sides of the interior of the rubber body, and liquid holes are provided at both upper and lower ends of the rubber body.

[0010] Preferably, the outer side of the blocking block slides sealingly with the inner wall of the sliding groove.

[0011] Preferably, air grooves are provided on both sides of the rubber body.

[0012] Beneficial effects of the utility model:

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, the utility model provides a rubber structure with flame retardant function, including a rubber body 1, liquid cavities 3 are provided on both sides of the interior of the rubber body 1, the liquid cavity 3 is used to store liquid, the interior of the liquid cavity 3 is filled with liquid, and nitrogen-based liquid flame retardants are mostly found in intumescent flame retardants. During the heating process, this type of chemical can release ammonia to form a foam-like carbon layer covering the surface of the material, thereby isolating the contact between fuel and air. The liquid is a nitrogen-based liquid, and a slide groove 6 is provided inside the rubber body 1. Blocks 10 are slidably connected to both sides of the interior of the slide groove 6. The block 10 has a certain blocking effect and can prevent the liquid from leaking out of the interior of the liquid cavity 3. The opposite sides of the two block blocks 10 are fixedly connected with memory metal 7, and the memory metal 7 can shrink when heated. The opposite sides of the two block blocks 10 are fixedly connected with connecting rods 5, and the connecting rods 5 are used for connecting. One side of the connecting rod 5 is fixedly connected with a push plate 4, and the movement of the connecting rod 5 can The rubber body 1 is capable of driving the push plate 4 to move. The upper and lower positions of the inner sides of the rubber body 1 are provided with cavities 11 connected to the slide groove 6. The upper and lower sides of the rubber body 1 are provided with connecting cavities 9. The upper and lower ends of the rubber body 1 are provided with liquid holes 2. The liquid holes 2 are used to discharge the liquid to the outside of the rubber body 1. The outer side of the block 10 is sealed and slid with the inner wall of the slide groove 6. One side of the cavity 11 is arranged in an inclined arc shape. The arc shape can achieve a better effect when discharging liquid. The rubber body (1) is provided with air grooves (12) on both sides. When the push plate 4 moves, no negative pressure will occur through the arranged air grooves 12, so that the movement of the push plate 4 is smoother.

[0023] When encountering an open flame, the memory metal 7 shrinks due to the heat. When shrinking, the memory metal 7 pulls the block 10 to move inside the slide groove 6. When moving, the block 10 drives the connecting rod 5 to move. The connecting rod 5 drives the push plate 4 to move. When the push plate 4 moves, it applies pressure to the liquid inside the liquid cavity 3, thereby pushing the liquid into the slide groove 6. The liquid enters the cavity 11 through the slide groove 6, and then enters the inside of the connecting cavity 9, and is finally discharged from the liquid hole 2, so that the liquid adheres to the surface of the rubber body 1, thereby achieving a flame retardant effect, thereby improving the safety of the rubber body 1.

[0024] like Figure 2 and Figure 4As shown, both sides of the rubber body 1 are fixedly connected with first springs 13, and the opposite sides of the two first springs 13 are fixedly connected with one side of the corresponding push plate 4. A groove 15 is provided on the inner wall of the rubber body 1, and a second spring 16 is fixedly connected inside the groove 15, and one end of the second spring 16 is fixedly connected with an arc-shaped clamping block 14;

[0025] When there is no open flame, the arc-shaped block 14 is set to limit the movement of the push plate 4 under the action of the second spring 16. When the memory metal 7 contracts, the pulling force on the push plate 4 increases, thereby causing the arc-shaped block 14 to move toward the inside of the groove 15. At this time, the push plate 4 moves, and the push plate 4 is pushed to move under the action of the first spring 13, so that the push plate 4 moves more smoothly, thereby improving the drainage effect.

[0026] like Figure 3 As shown, a rectangular groove 8 is provided inside the connecting rod 5;

[0027] The rectangular groove 8 can achieve a better effect when draining the liquid from the liquid chamber 3 .

[0028] Working principle: when encountering an open flame, the memory metal 7 shrinks due to heat. When shrinking, the memory metal 7 pulls the block 10 to move inside the chute 6. When moving, the block 10 drives the connecting rod 5 to move. The connecting rod 5 drives the push plate 4 to move. When the push plate 4 moves, it applies pressure to the liquid inside the liquid cavity 3, thereby pushing the liquid into the chute 6. The liquid enters the cavity 11 through the chute 6, and then enters the inside of the connecting cavity 9, and finally is discharged from the liquid hole 2, so that the liquid adheres to the surface of the rubber body 1, thereby achieving a flame retardant effect, thereby improving the safety of the rubber body 1.

[0029] Furthermore, when there is no open flame, the arc-shaped block 14 is set to limit the movement of the push plate 4 under the action of the second spring 16. When the memory metal 7 contracts, the pulling force on the push plate 4 increases, thereby causing the arc-shaped block 14 to move toward the inside of the groove 15. At this time, the push plate 4 moves, and the push plate 4 is pushed to move under the action of the first spring 13, so that the push plate 4 moves more smoothly, thereby improving the drainage effect.
