Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber installation, and in particular to a construction method for inserting optical fibers through walls into homes. Background Art

[0002] With the development of the Internet, our lives are becoming more and more dependent on broadband networks. At present, when building houses, fiber optic cables are basically pre-buried. However, for old houses, if broadband networks need to be added, it is necessary to first drill a hole in the wall of the house and then pass the optical fiber through the hole into the house.

[0003] The existing invention patent with publication number CN115508964A discloses an auxiliary laying device for optical fiber installation. By adding airbag ring 2 and airbag ring 3 to the outside of the wall-penetrating tube, the gap between the wall-penetrating tube and the reserved hole is filled to prevent dust inside the reserved hole from being blown out. Clamping nails are added to the surface of the connecting ring to fix the wall-penetrating tube when it is installed inside the reserved hole.

[0004] In the above technical solution, in order to realize the installation of the wall-penetrating pipe, it is necessary to first open a reserved hole in the wall for installing the wall-penetrating pipe. After the wall-penetrating pipe is installed in this reserved hole, the airbag ring 2 and the airbag ring 3 are used to fill the gap between the wall-penetrating pipe and the reserved hole, thereby realizing the isolation of dust. However, when it rains, rainwater outside the house will penetrate into the interior of the house along the optical fiber, the reserved hole and the wall-penetrating pipe, causing certain negative effects.

[0045] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figure 1-10 As shown, a construction method of optical fiber penetration through a wall into a home of the present invention comprises the following steps:

[0047] S1, use an electric drill to open a hole for wiring on the wall of the house, with the end of the hole inside the house higher than the end of the hole outside the house; Figure 1As shown in the figure, the filled part is the house wall, and a wire hole is opened in the house wall. The left side of the house wall in the figure is the exterior of the house, and the right side is the interior of the house. Since the end of the wire hole located outside the house is lower than the end located inside the house, moisture outside the house will not penetrate into the interior of the house through the wire hole; the angle between the wire hole and the horizontal plane is α, 0°<α<90°, and 0≤h·tanα-d / cosα≤5mm, where h is the thickness of the house wall and d is the inner diameter of the wire hole. Figure 1 As can be seen from the figure, h·tanα is the height difference between the two ends of the threading hole, and d / cosα is the distance between the top and bottom sides of the threading hole. The difference between the two is in the range of 0-5, which means that the bottom side of the threading hole located inside the house wall is 0-5mm higher than the top side of the threading hole located outside the house wall. In this state, it can not only prevent moisture from the outside of the house from entering the inside of the house through the threading hole, but also reduce the bending angle of the optical fiber to prevent optical fiber damage; the angle between the threading hole and the vertical plane is β, 0°<β<90°, such as Figure 2 As shown, the wire threading hole and the vertical plane form an angle within the range of 0-90 degrees, which can also reduce the bending angle of the optical fiber in the wire threading hole and improve the protection performance of the structure for the optical fiber.

[0048] As a preferred embodiment, it is best to set h·tanα=d / cosα, that is, the bottom side of the wire hole at one end of the house wall is at the same height as the top side of the wire hole at the other end of the house wall. In this state, it is ensured that moisture outside the house will not enter the house through the wire hole, and the bending angle of the optical fiber is minimized in the vertical plane. At the same time, β is preferably set to 45°. In this state, the bending angle of the optical fiber in the horizontal plane is ensured to be small, and drilling construction is also convenient.

[0049] As a preferred embodiment, since the angle of the threading hole is limited, it is not only inconvenient to control the electric drill when punching holes in the wall of the house, but also the straightness of the threading hole cannot be guaranteed. Therefore, before the punching operation, a slide rail bracket 2 for limiting the electric drill can be fixed on the wall of the house. The slide rail bracket 2 includes a fixed seat 21, a guide rail 22, a slide seat 23 and a telescopic rod 24. The fixed seat 21 is used to be fixed to the wall of the house; one end of the guide rail 22 is set on the fixed seat 21, and the guide rail 22 is rotatably connected to the fixed seat 21, and the angle between the guide rail 22 and the fixed seat 21 in the horizontal plane is 45°; the slide seat 23 is set on the guide rail 22, and the slide seat 23 is slidably connected to the guide rail 22, and the slide seat 23 is used to be fixed to the electric drill; the two ends of the telescopic rod 24 are respectively set on the fixed seat 21 and the guide rail 22, and the telescopic rod 24 is rotatably connected to the fixed seat 21 and the guide rail 22; Figure 10As shown, the included angle between the guide rail 22 and the fixing base 21 is fixedly set to 45°, which is suitable for most scenarios. By adjusting the installation direction of the fixing base 21, the optical fiber can be inserted from the left or right, as shown in FIG. Figure 9 As shown, when the slide rail bracket 2 is installed on the wall of the house in this state, the optical fiber is inserted from the left side. If it is rotated 180° on the plane of the house wall, a threading hole for insertion from the right side can be made; Figure 8 As shown, by setting a telescopic rod 24 between the guide rail 22 and the fixed seat 21, the angle of the guide rail 22 on the vertical plane can be adjusted by utilizing the telescopic adjustment of the telescopic rod 24, thereby adjusting the angle of the electric drill on the vertical plane, thereby drilling a threading hole that meets the requirements.

[0050] S2, take out two sealing devices 1 and fix them at the two ends of the threading hole respectively. The sealing devices 1 are used to enhance the sealing performance between the optical fiber and the threading hole.

[0051] As a preferred embodiment, the sealing device 1 includes a supporting plate 11, a wire tube 12, an elastic rope 13 and a hook 14, wherein the supporting plate 11 is a circular plate-shaped structure; the wire tube 12 is fixedly arranged on the supporting plate 11, and the wire tube 12 is located in the threading hole; both ends of the elastic rope 13 are fixedly arranged on the wire tube 12; the hook 14 is fixedly arranged on the wire tube 12, and the hook 14 and the elastic rope 13 are arranged on the outside of the wire tube 12 relative to each other, and the elastic rope 13 is engaged with the hook 14; Figure 3-6 As shown, when two sealing devices 1 are relatively arranged at the two ends of the threading hole, the sealing devices 1 can be firmly fixed in the threading hole by utilizing the engagement of the elastic rope 13 on one sealing device 1 with the hook 14 on the other sealing device 1.

[0052] Furthermore, in order to improve the sealing effect of the sealing device 1, the end of the wire tube 12 close to the abutment plate 11 can be set as a circular ring, and the end away from the abutment plate 11 can be set as a rectangular ring, that is, the wire tube 12 is set as a flat mouth structure, so that when optical fibers of different specifications pass through the wire tube 12, it can maintain a relatively sealed state; however, in this state, it is not easy for the optical fiber to pass through the end of the wire tube 12 away from the abutment plate 11. In order to solve this problem, two flange plates 15 can be relatively provided at the end of the wire tube 12 away from the abutment plate 11, and the spacing between the two flange plates 15 gradually increases in the direction away from the abutment plate 11, so that the insertion of the optical fiber is more convenient; specifically, Figure 5 As shown, the flange plate 15 is preferably configured as an arc-shaped plate structure, which can not only solve the above problems but also enhance the structural strength of the device.

[0053] Furthermore, in order to improve the sealing effect of the sealing device 1, a sealing protrusion 16 can be provided in the sealing device 1. The sealing protrusion 16 is fixedly provided on the side of the supporting plate 11 close to the wire tube 12. By utilizing the contact between the sealing protrusion 16 and the wall of the house, the sealing performance between the supporting plate 11 and the wall of the house can be improved, and the supporting plate 11 and the wall of the house can be sealed. Specifically, the sealing protrusion 16 is an arc-shaped rod-shaped structure with a wedge-shaped end face. The sealing protrusion 16 is provided with two circles, each circle is provided with a plurality of sealing protrusions, and the multiple sealing protrusions 16 in each circle are arranged in a circular manner, such as Figure 6 As shown, the sealing protrusions 16 of the inner and outer rings can be set to 4, and the four sealing protrusions 16 of the outer ring are respectively located at the top, bottom, left and right, and the four sealing protrusions 16 of the inner ring are respectively located at the upper left, lower left, upper right and lower right. When the supporting plate 11 is attached to the wall of the house, the sealing protrusions 16 can be deformed to improve the sealing effect between the supporting plate 11 and the wall of the house, and the guidance of multiple sealing protrusions 16 can prevent moisture from entering the threading hole.

[0054] S3, insert the optical fiber into the sealing device 1, so that the optical fiber passes from the outside of the house to the inside of the house, and use the sealing device 1 to seal the optical fiber and the threading hole, thereby realizing the construction operation of optical fiber passing through the wall into the house.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
