Description

Technical Field

[0001] This utility model relates to the field of invisible optical cable technology, specifically a self-adhesive invisible optical cable and its matching laying device. Background Technology

[0002] Invisible fiber optic cable is a type of fiber optic cable designed specifically for indoor or short-distance scenarios that is "almost invisible". It mainly solves the problem of the aesthetic impact of traditional fiber optic cabling. Its core features are that it is extremely thin, transparent and invisible. The laying device usually refers to a laying gun, which can be used to heat the glue at the fiber optic cable for laying.

[0003] A search revealed a Chinese patent for a self-adhesive invisible optical cable, publication number CN211148994U, which includes an outer sheath and an optical unit. The cross-sectional shape of the outer sheath has at least one side, and this side is set as a concave arc. The outer sheath is made of a soft and elastic material.

[0004] When the main body of the outer sheath of the aforementioned self-adhesive invisible optical cable adopts an isosceles right triangle with a concave arc, each surface of the outer sheath is a concave arc surface; and when the optical fiber, tight-buffered sheath, and outer sheath are all made of transparent materials; at the right-angle corners of various buildings, especially where many buildings now have transparent glass frames, wiring can be completed without any fixing objects. However, it only changes the shape of the sheath and fixes it to the building through the sheath. Its self-adhesion is poor, which can easily cause the optical cable to fall off shortly after it is laid. In addition, the current invisible optical cable requires the production of sub-cables and secondary adhesive processing. During the processing, the hot melt adhesive is inevitably damaged irreversibly due to the process or storage environment, which reduces the service life of the adhesive. Utility Model Content

[0005] The purpose of this invention is to provide a self-adhesive invisible optical cable and a matching laying device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A self-adhesive invisible optical cable includes an invisible optical cable body, which is composed of a transparent sheath, a bare optical cable body, and hot melt adhesive. The bare optical cable body is installed inside the upper part of the transparent sheath. A storage cavity is provided inside the lower part of the transparent sheath, and the hot melt adhesive is located inside the storage cavity. The top surface of the transparent sheath is arc-shaped, and the bottom surface of the transparent sheath is flat.

[0007] Preferably, the upper part of the storage cavity is arranged in a "△" shape, and the transparent sheath is made of a low-refractive-index transparent perfluoroalkoxy resin material.

[0008] This utility model also discloses a matching laying device for a self-adhesive invisible optical cable, including a heating laying gun body and a heating gun head adapted to the invisible optical cable body. The rear end of the heating laying gun body is provided with a control section, and the heating gun head is installed at the end of the control section away from the heating laying gun body. A limiting block is provided at the center of the top of the heating gun head, and the top surface of the limiting block is provided with an arc groove adapted to the arc surface of the transparent sheath.

[0009] Preferably, the top of the heating gun head is fitted with an anti-detachment cover plate via a torsion spring shaft, the bottom surface of the anti-detachment cover plate is provided with a limiting groove that adapts to the plane of the transparent sheath, and a slot that adapts to the body of the invisible optical cable is provided on one side of the heating gun head near the front.

[0010] Preferably, a limiting rod is provided inside the heating gun head and in front of the limiting block on both sides, and the distance between the two limiting rods is adaptively matched with the side length of the transparent sheath.

[0011] Preferably, the anti-detachment cover has an adjustment cavity inside, and a peeling knife is slidably installed in the adjustment cavity via a slider. A threaded push rod is fixedly installed at the center of the top of the slider. An internal threaded sleeve is threadedly connected to the top of the threaded push rod. The internal threaded sleeve is rotatably installed inside the anti-detachment cover. A rotating block is fixedly connected to the top of the internal threaded sleeve, and the top of the rotating block has an internal hexagonal wrench groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention, by setting up an invisible optical cable body and a heated laying gun body to work together, eliminates the need for secondary adhesive application during laying. The cable can be laid after the transparent sheath is cut open and heated, which improves the performance. Furthermore, the hot melt adhesive is inside the transparent sheath, preventing the viscosity of the hot melt adhesive from decreasing due to humid storage or environmental conditions during transportation.

[0013] By setting up a limiting block, heating gun head, anti-detachment cover plate, and stripping knife to work together, the invisible optical cable body can be inserted between the limiting block and the anti-detachment cover plate during installation, so that the transparent sheath can be accurately cut open by the stripping knife, exposing the liquid hot melt adhesive, which is convenient for subsequent installation and fixation. Furthermore, the rotating block, threaded push rod, and internal threaded sleeve work together to make it easy to adjust the cutting position of the stripping knife, which is highly flexible in use.

Detailed Implementation

[0019] 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. Example 1

[0020] Combination Figures 1-4 A self-adhesive invisible optical cable includes an invisible optical cable body 2, which is composed of a transparent sheath 17, a bare optical cable body 14, and hot melt adhesive 16. A matching laying device for the self-adhesive invisible optical cable includes a heating laying gun body 1 and a heating gun head 4 that is compatible with the invisible optical cable body 2. A control section 3 is provided at the rear end of the heating laying gun body 1, and the heating gun head 4 is installed at the end of the control section 3 away from the heating laying gun body 1.

[0021] See Figure 4 Furthermore, the upper part of the storage cavity 15 is arranged in a "△" shape, the transparent sheath 17 is made of a low refractive index transparent perfluoroalkoxy resin material, the bare optical cable body 14 is installed inside the transparent sheath 17 at the upper position, the storage cavity 15 is arranged inside the transparent sheath 17 at the lower position, and the hot melt adhesive 16 is located inside the storage cavity 15. The top surface of the transparent sheath 17 is an arc surface, the bottom surface of the transparent sheath 17 is a plane, and the heating gun head 4 is provided inside and in front of the limiting block 5 at the two sides with limiting rods 6, and the distance between the two limiting rods 6 is adaptively matched with the side length of the transparent sheath 17.

[0022] Specifically, since both the bare optical cable body 14 and the hot melt adhesive 16 are inside the transparent sheath 17, no secondary adhesive injection is required during on-site installation, allowing for immediate installation upon unpacking. Furthermore, by wrapping the hot melt adhesive 16 in the transparent sheath 17, a pre-encapsulated structure can be formed, ensuring that the hot melt adhesive 16 is completely isolated from external moisture, dust, high temperatures, and other transportation and storage environments. This reduces the risk of moisture absorption and viscosity reduction, aging, and clumping of the adhesive. Regardless of long-distance transportation during the rainy season or long-term storage, the viscosity can remain stable, resulting in a longer service life. Example 2

[0023] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, a limiting block 5 is provided at the center of the top of the heating gun head 4. The top surface of the limiting block 5 is provided with an arc groove that adapts to the arc surface of the transparent sheath 17. An anti-detachment cover plate 8 is installed at the top of the heating gun head 4 via a torsion spring shaft. The bottom surface of the anti-detachment cover plate 8 is provided with a limiting groove that adapts to the plane of the transparent sheath 17. A slot 7 that adapts to the invisible optical cable body 2 is provided at the front side of the heating gun head 4. An adjustment cavity is provided inside the anti-detachment cover plate 8. A stripping knife 13 is slidably installed in the adjustment cavity via a slider 12. A threaded push rod 11 is fixedly installed at the center of the top of the slider 12. An internal threaded sleeve 9 is threadedly connected to the top of the threaded push rod 11. The internal threaded sleeve 9 is rotatably installed inside the anti-detachment cover plate 8. A rotating block 10 is fixedly connected to the top of the internal threaded sleeve 9, and an internal hexagonal wrench groove is opened at the top of the rotating block 10.

[0024] Specifically, during installation, since the anti-detachment cover 8 is mounted on the heating gun head 4 via a torsion spring shaft, it can be moved away from the limiting block 5. Then, the invisible optical cable body 2 can be inserted into the heating gun head 4 from the slot 7, ensuring that the hot melt adhesive 16 faces the anti-detachment cover 8, and that the arc-shaped surface of the transparent sheath 17 fits against the arc-shaped groove of the limiting block 5. Simultaneously, it must be ensured that the invisible optical cable body 2 is positioned between the two limiting rods 6. Afterward, the restriction on the anti-detachment cover 8 can be released, allowing it to reset under the action of the torsion spring shaft, thus completing the fixing process of the invisible optical cable body 2. During subsequent heat application, simply align the matching heating installation gun body 1 with the wall and control the heating gun head 4 at the control section 3 to heat the optical cable to 120°C. At this point, the hot melt adhesive 16 rapidly melts into a highly fluid liquid. At the same time, the stripping knife 13 at the anti-detachment cover plate 8 simultaneously cuts open the lower edge of the transparent sheath 17. Subsequent personnel can pull the heating and laying gun body 1 with one hand to move it in the laying direction. The unheated invisible optical cable body 2 will be guided to the space between the heating gun head 4 and the anti-detachment cover plate 8 through the limiting rod 6 and the limiting block 5. Meanwhile, another person can hold the heated invisible optical cable body 2 with their hand. Since the transparent sheath 17 has been cut open and the hot melt adhesive 16 has been heated into a liquid, pressure can be applied to precisely squeeze out the hot melt adhesive 16 so that the invisible optical cable body 2 can be adhered to the wall. This achieves the laying steps of heating, dispensing adhesive, and pasting the entire invisible optical cable body 2 at the same time, without the need for tedious procedures such as real-time glue replenishment. Personnel must wear heat-insulating work gloves during the laying process to prevent burns.

[0025] In actual operation, the steps of how the heat gun heats the invisible optical cable body 2 in the existing technology will not be described in detail here. Simply put, heating elements are provided on the inner sides of both the heating gun head 4 and the anti-detachment cover 6. The heating element of the heating gun head 4 is located inside or on the bottom surface of the limiting block 5, and the heating element of the anti-detachment cover 8 is located inside the cover and corresponds to the limiting groove. The heating element has a long through hole for the stripping knife 13 to pass through. Of course, it is also possible to choose to provide a heating element only on one side of the heating gun head 4 or the anti-detachment cover 8 to meet the requirements. As long as the usage needs are met, since both the bare optical cable body 14 and the hot melt adhesive 16 are inside the transparent sheath 17, no secondary adhesive injection is required during on-site laying. It can be laid immediately after opening the package. Furthermore, by wrapping the hot melt adhesive 16 in the transparent sheath 17, a pre-encapsulated structure can be formed to ensure that the hot melt adhesive 16 is completely isolated from the external moisture, dust, high temperature and other transportation and storage environments. This reduces the risk of moisture absorption and viscosity reduction, aging and clumping of the adhesive. Whether it is long-distance transportation in the rainy season or long-term storage, the viscosity can remain stable and the service life is relatively long. During installation, since the anti-detachment cover plate 8 is mounted on the heating gun head 4 via a torsion spring shaft, it can be moved away from the limiting block 5. Then, the invisible optical cable body 2 can be placed into the heating gun head 4 from the slot 7, ensuring that the hot melt adhesive 16 faces the anti-detachment cover plate 8, and that the arc-shaped surface of the transparent sheath 17 fits into the arc-shaped groove of the limiting block 5. At the same time, it is necessary to ensure that the invisible optical cable body 2 is between the two limiting rods 6. Then, the restriction on the anti-detachment cover plate 8 can be released, allowing it to reset under the action of the torsion spring shaft, thus completing the process of fixing the invisible optical cable body 2. During subsequent heat application, it is only necessary to align the matching heating installation gun body 1 with the wall and control the heating gun head 4 to heat the optical cable to 120°C through the control section 3. At this time, the hot melt adhesive 16 quickly melts into a liquid with excellent fluidity, while the transparent sheath 17 is made of transparent perfluoroalkoxy resin with low refractive index. Its continuous temperature resistance is around 200℃ and it will not be damaged by overheating. At the same time, the peeling knife 13 at the anti-detachment cover plate 8 simultaneously cuts open the lower edge of the transparent sheath 17, and the subsequent personnel can pull the heating and laying gun body 1 with one hand to move it in the laying direction. The unheated invisible optical cable body 2 will be guided through the limiting rod 6 and the limiting block 5 to the space between the heating gun head 4 and the anti-detachment cover plate 8. At the same time, another person can hold the heated invisible optical cable body 2 with their hand. Since the transparent sheath 17 has been cut open and the hot melt adhesive 16 has been heated into a liquid, pressure can be applied to precisely squeeze out the hot melt adhesive 16 so that the invisible optical cable body 2 can be adhered to the wall. This achieves the laying steps of heating, dispensing adhesive, and pasting the entire invisible optical cable body 2 at the same time, without the need for tedious procedures such as real-time glue replenishment. Personnel must wear heat-insulating work gloves during the laying process to prevent burns. Furthermore, the peeling knife 13 is mounted on the threaded push rod 11 via the slider 12. At the same time, the threaded push rod 11 is threadedly connected to the inner threaded sleeve 9. Since the inner threaded sleeve 9 is fixedly connected to the rotating block 10, and the inner threaded sleeve 9 and the rotating block 10 are rotatably mounted on the anti-detachment cover plate 8, and the top surface of the rotating block 10 is provided with an internal hex wrench groove, the rotating block 10 can be rotated with the help of a suitable internal hex wrench, thereby driving the inner threaded sleeve 9 to rotate, and pushing the threaded push rod 11 up and down with the thread to adjust the position of the peeling knife 13. By rotating clockwise or counterclockwise, the peeling knife 13 is adjusted to a suitable cutting position to ensure that it can accurately cut open the transparent sheath 17. There is no anti-detachment device between the threaded push rod 11 and the inner threaded sleeve 9. Under safe conditions, the threaded push rod 11 can be completely unscrewed by continuously rotating the inner threaded sleeve 9, thereby replacing the peeling knife 13.
