Description

Technical Field

[0001] This utility model relates to the field of signal line technology, specifically to a fireproof and flame-retardant signal transmission line. Background Technology

[0002] Signal transmission lines are physical media used to transmit electrical or optical signals between electronic devices or systems. Their performance directly affects the integrity, transmission speed, and reliability of the signal.

[0003] However, current signal transmission lines lack fire-retardant properties or have poor flame-retardant effects. When flames appear in the outside, they can easily burn through the outer protective layer of the signal transmission line, causing damage and short circuits, thus affecting the service life of the signal transmission line. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fireproof and flame-retardant signal transmission line, which can break the ring containing flame-retardant liquid in advance and spray out the flame-retardant liquid to retard the surrounding area, thereby solving the problem mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a fireproof and flame-retardant signal transmission line, comprising a transmission line body and multiple open rings. The outer surface of the transmission line body protrudes to form multiple thickened portions with annular structures. Each thickened portion is provided with an annular positioning groove. Each open ring is disposed in the positioning groove. Both ends of the open ring are bent to form connecting portions. The connecting portions are fitted together. A ring body is installed on the outside of the open ring. Each ring body is provided with a liquid storage chamber. Each liquid storage chamber stores flame-retardant liquid. Each opposite surface of the connecting portion is provided with an arc-shaped groove. Each inner wall of the arc-shaped groove is vertically installed with a half rod. Adjacent half rods are combined to form a positioning post. Each positioning post is fitted with a positioning sleeve.

[0006] As a preferred technical solution, each ring body has a vertically provided limiting groove on one side of the arc groove, and the outer ring surface of the positioning sleeve protrudes to form a limiting part at the limiting groove. The limiting part is slidably disposed in the limiting groove, and a compression spring is installed between the limiting part and the limiting groove.

[0007] As a preferred technical solution, the half-bars are set at different heights, and the height of the positioning sleeve is greater than the height of the lower half-bar.

[0008] As a preferred technical solution, the exposed end of the positioning sleeve is expanded outward to form a ring-shaped flange.

[0009] As a preferred technical solution, all rings are arranged in a "C" shape and are made of silicone material.

[0010] As a preferred technical solution, the open rings are all made of flame-retardant thermoplastic elastomer.

[0011] As a preferred technical solution, the radius of the positioning sleeve is matched with the radius of the arc groove.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, and multiple rings are installed on the outside of the transmission line body. The rings are easy to install and remove. The transmission line body can be suspended in the air by the rings, which avoids the transmission line body from being damaged by friction with the ground or other surfaces when pulled. In the event of a fire, the silicone material is burned through first, so that the internal flame retardant liquid can be squeezed out and sprayed around, which can achieve the flame retardant effect and prevent the flame from spreading along the transmission line body, thus increasing safety.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0022] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a fireproof and flame-retardant signal transmission line, comprising a transmission line body 1 and multiple open rings 7. The transmission line body 1 has multiple annular thickened portions 2 protruding from its exterior. Each thickened portion 2 is provided with an annular positioning groove 6. The open rings 7 are all disposed in the positioning grooves 6. Both ends of the open rings 7 are bent to form connecting portions 4, which are fitted together. A ring body 3 is installed on the outside of the open rings 7. Each ring body 3 has a liquid storage chamber inside, which stores flame-retardant liquid. An arc-shaped groove 8 is provided on the opposite surface of the connecting portions 4. Half rods 10 are vertically installed on the inner wall of each arc-shaped groove 8. Adjacent half rods 10 are combined to form positioning posts. Positioning sleeves 5 are fitted on the outside of each positioning post. The flame-retardant liquid is a liquid flame retardant, which allows it to be sprayed out smoothly.

[0024] In this embodiment, each ring 3 has a vertically provided limiting groove on one side of the arc groove 8. The outer ring surface of the positioning sleeve 5 protrudes to form a limiting part 11 opposite to the limiting groove. The limiting part 11 is slidably disposed in the limiting groove. A compression spring 9 is installed between the limiting part 11 and the limiting groove.

[0025] In this embodiment, the half rods 10 are set at different heights, and the height of the positioning sleeve 5 is greater than the height of the lower half rod 10.

[0026] In this embodiment, the exposed end of the positioning sleeve 5 is expanded outward to form an annular flange, which facilitates pulling the positioning sleeve outward.

[0027] In this embodiment, all rings 3 are arranged in a "C" shape and are made of silicone material. The flame retardant effect of silicone is lower than that of the outer protective layer of the transmission line body, which allows the rings to ignite first. The rings are elastic, so they can expand after the flame retardant liquid is injected inside. Therefore, after burning through, the rebound of the rings can quickly squeeze out the flame retardant liquid inside.

[0028] In this embodiment, the opening rings 7 are all made of flame-retardant thermoplastic elastomer, which makes the opening rings elastic and able to open outward smoothly.

[0029] In this embodiment, the radius of the positioning sleeve 5 is matched with the radius of the arc groove 8, so that the positioning sleeve can only move up and down along the arc groove, avoiding tilting and swinging.

[0030] During installation, the positioning sleeve is pulled outward by flipping the flange, causing it to move outward along the limiting groove. After the positioning sleeve moves away from the lower half of the rod, the opening ring can be pried open outward. The opened opening ring can be directly fitted into the positioning groove. After being released, the opening ring automatically closes due to its own elasticity and is clamped in the positioning groove. After the positioning sleeve is released, the rebound of the compression spring pushes the limiting part and the positioning sleeve downward, allowing the positioning sleeve to be fitted onto the positioning post again, preventing the opening ring from opening on its own. This increases the stability of the installation. The above installation and disassembly are also relatively convenient, making it easy to disassemble and replace.

[0031] The ring structure suspends the transmission line body, preventing damage caused by friction between the transmission line body and the ground or other surfaces when pulled.

[0032] Furthermore, in the event of a fire, the silicone material is burned through first. Because the ring is in an expanded state due to the internal flame retardant liquid, once the hole is broken, the internal flame retardant liquid can be squeezed out and sprayed around and onto the side on fire, achieving a flame retardant effect (mainly suitable for small fires, such as fires in electrical distribution cabinets), preventing the flame from spreading along the transmission line body and increasing safety.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
