Abstract
Description
Technical Field
[0001] This utility model relates to the field of flame retardant technology, and more specifically, to a silicone rubber flame retardant structure. Background Technology
[0002] The flame-retardant structure of silicone rubber can be achieved by adding flame retardants, optimizing material composition, or using composite design. Although silicone rubber itself is flammable, by adding flame retardants or using composite structures, a heat insulation layer or char layer can be formed under flames to prevent the spread of fire.
[0003] Among existing publicly available documents, patent publication number CN220121514U discloses a fire-retardant silicone rubber cable sheath. This technology utilizes a wear-resistant layer and a tear-resistant layer. The middle protective sheath, from the outside to the inside, includes a sealing and waterproof layer and a heat-insulating layer. The inner protective sheath, from the outside to the inside, includes a tightening layer, an anti-interference shielding layer, and a silicone rubber insulating sleeve. The fire-retardant silicone rubber cable sheath provided by this utility model possesses high mechanical strength, thermal shock resistance, toughness, impact resistance, wear resistance, and electrical properties, and exhibits stable chemical properties. However, this technology still has the following problems.
[0004] In the process of making silicone rubber flame retardant, the flame retardant part needs to be fitted onto the outer wall of the object. Due to the different sizes of the objects, it is difficult to adjust the flame retardant coverage area according to the needs of use, and the adjustability of the flame retardant coverage is poor. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a silicone rubber flame-retardant structure, comprising a silicone rubber sleeve, one end of which is fixedly connected to a linkage ring, and one end of the linkage ring is provided with an adjusting member, the adjusting member comprising: A fixing sleeve is fixed to one end of the linkage ring, and multiple limiting blocks are fixed to the outside of the fixing sleeve; Each connecting block is located on one side of the limiting block. When the connecting block moves, it is limited and blocked by the limiting block. A flame-retardant sleeve is installed on the top of the connecting block, and multiple connecting blocks are fixedly connected to the flame-retardant sleeve. The positioning ring is fixed to one end of the flame-retardant sleeve.
[0006] In a preferred embodiment, an annular gap is provided between the flame-retardant sleeve and the fixed sleeve, and the connecting block is slidably connected to the fixed sleeve.
[0007] In a preferred embodiment, a plurality of limiting blocks are arranged in an arc shape, and the top of the limiting blocks are slidably connected to the flame-retardant sleeve.
[0008] In a preferred embodiment, the inner diameter of the fixing sleeve is smaller than the inner diameter of the silicone rubber sleeve, and both the fixing sleeve and the flame-retardant sleeve are made of silicone rubber.
[0009] In a preferred embodiment, the inner diameter of the silicone rubber sleeve is larger than the inner diameter of the positioning ring, and the center point of the positioning ring and the center point of the fixing sleeve are on the same horizontal line.
[0010] In a preferred embodiment, a support ring is fixed to the outer wall of the positioning ring; Two pressure strips are fixedly connected to the outer wall of the support ring. Each pressure strip has a pressure groove embedded in its upper surface. The pressure groove is used to position the hand and press.
[0011] In a preferred embodiment, an adhesive pad is fixed to the lower surface of each of the pressure strips, and the adhesive pad has a rectangular cross-sectional shape.
[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts an adjusting component. The positioning ring drives the flame-retardant sleeve to move to the left, keeping the silicone rubber sleeve stationary. The connecting block slides to the left along the outer wall of the fixed sleeve. At the same time, the connecting block drives the contact to the right side of the limiting block. The distance between the positioning ring and the linkage ring becomes longer, which can be adjusted according to the length of the object. This allows for adjustable flame-retardant treatment of the object, making the flame-retardant adjustable application more widely applicable. 2. After the positioning ring is adjusted, the inside of the groove is pressed by hand, and the pressure strip drives the adhesive pad to press down. The adhesive pad is then bonded to the upper surface of the base, ensuring that the positioning ring is stably placed in the designated position. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1 - Figure 4 The diagram shows a silicone rubber flame-retardant structure with an adjustable component. The adjustable component allows for adjustable flame-retardant treatment of the object. However, the applicability of the flame-retardant adjustment is poor. The specific structure of the adjustable component is as follows.
[0020] In this embodiment, as Figure 1 - Figure 3 As shown, one end of the linkage ring 2 is provided with an adjusting component, which includes: a fixed sleeve 6, fixed to one end of the linkage ring 2, with multiple limiting blocks 5 fixed to the outside of the fixed sleeve 6; each connecting block 4, located on one side of the limiting block 5, the connecting block 4 being limited and blocked by the limiting block 5 when moving, a flame-retardant sleeve 3 installed on the top of the connecting block 4, and multiple connecting blocks 4 being fixedly connected to the flame-retardant sleeve 3; and a positioning ring 7, fixed to one end of the flame-retardant sleeve 3. An annular gap is provided between the flame-retardant sleeve 3 and the fixed sleeve 6, and the connecting blocks 4 are slidably connected to the fixed sleeve 6. Multiple limiting blocks 5 are arranged in an arc distribution, and the tops of the limiting blocks 5 are slidably connected to the flame-retardant sleeve 3. The inner diameter of the fixed sleeve 6 is smaller than the inner diameter of the silicone rubber sleeve 1, and both the fixed sleeve 6 and the flame-retardant sleeve 3 are made of silicone rubber.
[0021] The inner diameter of the silicone rubber sleeve 1 is larger than the inner diameter of the positioning ring 7, and the center point of the positioning ring 7 and the center point of the fixing sleeve 6 are on the same horizontal line.
[0022] When using this silicone rubber flame-retardant structure, the positioning ring 7 moves to the left, causing the flame-retardant sleeve 3 to move while keeping the silicone rubber sleeve 1 stationary. This causes the flame-retardant sleeve 3 to move the connecting block 4 to the left, which slides along the outer wall of the fixed sleeve 6. Simultaneously, the connecting block 4 contacts the right side of the limiting block 5, thus the fixed sleeve 6 supports the limiting block 5, and the limiting block 5 limits the connecting block 4. This increases the distance between the positioning ring 7 and the linkage ring 2, allowing adjustment based on the object's length. Moving the positioning ring 7 inserts it onto the outer wall of the object, while the object moves along the positioning ring 7 into the fixed sleeve 6, then into the linkage ring 2, and finally into the silicone rubber sleeve 1.
[0023] In this embodiment, as Figure 3 - Figure 4As shown, a support ring 8 is fixed to the outer wall of the positioning ring 7; two pressure strips 9 are fixedly connected to the outer wall of the support ring 8, and a pressure groove 10 is embedded in the upper surface of each pressure strip 9. The pressure groove 10 is used to position the hand and press. An adhesive pad 11 is fixed to the lower surface of each pressure strip 9. The cross-sectional shape of the adhesive pad 11 is rectangular.
[0024] When using the silicone rubber flame-retardant structure, after the positioning ring 7 is adjusted, the pressure bar 9 is pressed down by hand by pressing the inside of the pressure groove 10. The pressure bar 9 drives the adhesive pad 11 down, and the adhesive pad 11 is bonded to the upper surface of the base. In this way, the adhesive pad 11 remains stationary, the pressure bar 9 supports the support ring 8, and the support ring 8 supports the positioning ring 7.
[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
