[0002] The new type of optical fiber heat shrink tubing, optical fiber fusion heat shrink tubing is a protective element used for optical fiber splicing, mainly composed of cross-linked polyolefin heat shrink tubing, hot melt tubing and reinforced stainless steel needles. Its main function is to protect the optical fiber splicing point and improve the mechanical strength without affecting the optical fiber's light-guiding properties. Its use method is to put the heat shrink tubing on the outside of the optical fiber and heat the optical fiber heat shrink tubing with a hot air gun or a match.

[0003] The existing new type of optical fiber heat shrink tubing has uneven force on the internal optical fiber, is easy to bend, and has poor insulation effect. For example, the utility model patent with authorization announcement number CN202472034U discloses a new type of optical fiber heat shrink tubing, which includes an inner layer body and an outer layer body made of heat shrink material, and two reinforced steel cores are symmetrically arranged between the inner layer body and the outer layer body. The diameter of the reinforced steel core is reduced by 50%. In the new type of optical fiber heat shrink tubing, the two reinforced steel cores are symmetrically distributed around the center line of the heat shrink tubing, so that the new type of optical fiber heat shrink tubing is evenly distributed after heating, so that during the heat shrinking process, the optical fiber wrapped in the heat shrink tubing is not deformed, ensuring the transmission performance of the optical fiber after hot melting, but the reinforced steel core is only on two sides, and the other two sides are still easily damaged, and the insulation effect is not good.

[0004] Therefore, we propose a new optical fiber heat shrink tubing to solve the problems of uneven force on the internal optical fiber, easy bending and poor insulation effect in the existing new optical fiber heat shrink tubing mentioned above. Utility Model Content

The outer layer 101 of the main body 1 is coated with a waterproof layer 2. The waterproof layer 2 coated on the outer layer 101 of the heat shrinkable sleeve main body 1 is a polyurethane waterproof coating, so that the heat shrinkable sleeve can be more waterproof. Steel blocks 3 are fixedly installed at equal angles inside the heat shrinkable sleeve main body 1, so that the new optical fiber heat shrinkable sleeve is evenly distributed after heating. The steel blocks 3 have thickness, which can prevent the optical fiber 5 from being burned by fire when the heat shrinkable sleeve is heated. The hardness of the steel block 3 is large, and the hardness of the main body 1 of the sleeve is small, so that the optical fiber 5 wrapped by the heat shrinkable tube is not easily deformed when it encounters a hard object, thereby ensuring the transmission performance of the optical fiber after hot melting. The steel blocks 3 fixed at equal angles inside the main body 1 are all hollow blocks, saving the material of the steel blocks;

[0022] The steel block 3 inside the main body 1 of the novel optical fiber heat shrinkable sleeve includes an outer wall 301 and an inner wall 302.
