Description

Technical Field

[0001] The utility model relates to the technical field of optical cable protection, in particular to a communication optical cable protection device. Background Technique

[0002] Communication optical cables provide people with fast Internet access speeds, facilitating people to receive external information. When laying a wall-piercing optical cable in a warehouse, it is necessary to pre-drill holes in the wall. After laying the optical cable, it is necessary to install a protective sleeve between the optical cable and the wall. The existing protective sleeve is arranged between the wall and the optical cable to reduce the friction when the optical cable moves on the wall. However, there is a gap between the optical cable and the protective sleeve, which is easy for mice to pass through. When mice drill into the warehouse through the wall hole, they will bite and damage the optical cables along the way, affecting the use of users. After retrieval, the publication number is (202220223761.3), which discloses a power communication optical cable bite protection device, including a fixing component. The fixing component is in two groups and is oppositely arranged on the surface of the corresponding optical cable protective sleeve. The fixing component includes an expansion ring, an adjusting screw and a pressing plate.

[0003] In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved; the tightening force of the above-mentioned bolts causes the expansion ring and the reed to deform, so as to tighten the wall gap and the cable channel gap. When the expansion ring and the reed are always in a deformed state, the durability value will decrease, and there is a problem of component loss. The method of using the deformation of the expansion ring to friction the inner hole of the wall to fix the protection device has poor stability and needs to be improved. Therefore, we propose a communication optical cable protection device. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Embodiment 1, as Figures 1-3As shown in the figure, the utility model provides a technical solution: a communication optical cable protection device, which includes an optical cable 1, semi-circular sleeves A 4 and semi-circular sleeves B 5 that are symmetrically spliced up and down. Threaded sections 3 are provided on the outer surfaces of both ends of the semi-circular sleeves A 4 and semi-circular sleeves B 5. Semi-circular sealing rings 6 are fixedly arranged on the inner surfaces of both ends of the semi-circular sleeves A 4 and semi-circular sleeves B 5. Retaining rings 2 are threadedly connected to the outer surfaces of both ends of the semi-circular sleeves A 4 and semi-circular sleeves B 5.

[0020] In a specific embodiment of the utility model, after the optical cable 1 passes through the hole in the wall, the semi-circular sleeves A 4 and semi-circular sleeves B 5 are sleeved on the penetration point of the optical cable 1 and the wall. The semi-circular sleeves A 4 and semi-circular sleeves B 5 are pressed tightly so that the semi-circular sealing rings 6 are in close contact with the outer insulating skin of the optical cable 1. Subsequently, the wedge-shaped lock block 8 is inserted into the wedge-shaped grooves 7 of the semi-circular sleeves A 4 and semi-circular sleeves B 5, which can temporarily fix the semi-circular sleeves A 4 and semi-circular sleeves B 5. Then, a retaining ring 2 is respectively arranged at both ends inside and outside the wall, and the retaining ring 2 is threaded with the threaded section 3 of the semi-circular sleeve. The retaining ring 2 can be used to clamp and fix the semi-circular sleeves A 4 and semi-circular sleeves B. At the same time, the two retaining rings 2 are in close contact with the wall surface at the same time, which can completely block and seal the wall gap. The semi-circular sealing ring 6 can press and seal the gap between the semi-circular sleeve and the optical cable 1. Multiple layers of semi-circular sealing rings 6 are provided to improve the sealing performance. By eliminating the gap where the optical cable passes through the wall, it is possible to prevent damage to the optical cable when a mouse passes through the gap; the semi-circular sealing ring 6 is made of fluororubber, which has excellent heat resistance and corrosion resistance. The semi-circular sleeves A 4, semi-circular sleeves B 5, and retaining rings 2 are all made of stainless steel, which has excellent corrosion resistance.

[0021] In the preferred technical solution, wedge-shaped grooves 7 are provided at the splicing joints of both ends of the semi-circular sleeves A 4 and semi-circular sleeves B 5. The wedge-shaped grooves 7 of the semi-circular sleeves A 4 and semi-circular sleeves B 5 are inlaid with the wedge-shaped lock block 8. Inserting the wedge-shaped lock block 8 into the wedge-shaped grooves 7 of the semi-circular sleeves A 4 and semi-circular sleeves B 5 can temporarily fix the semi-circular sleeves A 4 and semi-circular sleeves B 5, which is convenient for the subsequent installation of the retaining ring 2.

[0022] In the preferred technical solution, a number of convex strips 201 are integrally formed on the circumferential surface of the retaining ring 2. The convex strips 201 can increase the contact friction between the circumferential surface of the retaining ring 2 and the hand, thereby facilitating the rotation of the retaining ring 2 to be in close contact with the wall.

[0023] In the preferred technical solution, the number of semi-circular sealing rings 6 of the semi-circular sleeves A 4 and semi-circular sleeves B 5 is six each. The six semi-circular sealing rings 6 are symmetrically arranged about the vertical center line of the semi-circular sleeve A. Multiple layers of semi-circular sealing rings 6 are provided to improve the sealing performance.

[0024] In the preferred technical solution, one end of the semi-circular sealing ring 6 facing the open end surface of the semi-circular sleeve A is provided with a slope surface, and the slope surface is provided to facilitate the threading of the cable.

[0025] In the preferred technical solution, the inner diameter of the semi-circular sealing ring 6 is 1 mm smaller than the outer diameter of the outer skin of the optical cable 1, so that the semi-circular sealing ring 6 is in close contact with the insulating outer skin of the optical cable 1 in a sealed manner.

[0026] In summary, the sealing and plugging structure for the optical cable 1 passing through the wall avoids damage to the cable caused by rats passing through the gap where the optical cable 1 passes through the wall. By adopting a split semi-circular sleeve structure, the plugging can be carried out after the optical cable is installed in place, improving the installation flexibility.
