[0031] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] A fast optical fiber wiring device according to the present invention comprises an expansion nail and a sleeve, wherein a clamping head is provided at the tail of the expansion nail, and the sleeve is used for installing the optical fiber and is detachably connected to the clamping head.

[0033] Specifically, in actual applications, the expansion nail is hammered into the ground with a hammer or the like so that the clamp head just emerges from the ground surface, and then the expansion core is hammered in to fix the expansion nail to the ground surface; the optical fiber is installed in the sleeve, and the sleeve is firmly connected to the expansion nail through the clamp head, and the optical fiber is stably fixed close to the ground surface. Therefore, the application of the fast optical fiber wiring device avoids the deviation of the optical fiber due to the complex environment, and effectively solves the problem of the deviation of the optical fiber position.

[0034] In one example, the head of the expansion nail is conical, and the outer surface of the head is provided with a barb structure;

[0035] The head is provided with a plurality of slits arranged along the axial direction.

[0036] Specifically, the head of the expansion nail is conical. During the process of inserting the expansion nail into the ground, the conical design of the head makes it easier to insert the expansion nail into the ground, thereby effectively improving the construction efficiency; at the same time, the outer surface of the head is provided with a barb structure, which can increase the contact area between the head of the expansion nail and the ground, so that the expansion nail is more firmly fixed in the ground, thereby increasing the stability of the expansion nail; the head of the expansion nail is also provided with a plurality of split seams arranged along the axial direction. When the expansion core is inserted into the expansion nail, as the expansion core goes deeper, the head of the expansion nail splits, so that the contact area between the barb structure and the ground is further increased, thereby further increasing the stability of the expansion nail.

[0037] In one example, the diameter of the expansion nail is 0.5 cm to 10 cm; and / or

[0038] The length of the expansion nail is 10cm to 50cm.

[0039] Specifically, the size of the expansion screw can be flexibly selected according to the actual needs, and the thicker the expansion screw, the better the stability.

[0040] In one example, a blind hole arranged along the axial direction is provided in the expansion nail, and the blind hole extends from the end surface of the tail of the expansion nail to the head of the expansion nail;

[0041] The fast optical fiber wiring device also includes an expansion core, the length of the expansion core is greater than the length of the blind hole, and the expansion core can be inserted into the blind hole;

[0042] The closed end of the blind hole is in a cone shape, and one end of the expansion core is in a cone shape that is in matching contact with the closed end of the blind hole.

[0043] Specifically, the head of the expansion core also has a conical structure and is used in conjunction with the blind hole of the expansion nail. During the construction process, after the expansion nail is installed in place, a hammer or other tool is used to hit the tail of the expansion core and insert the expansion core into the blind hole of the expansion nail. As the expansion core is inserted, the head of the expansion nail is also stretched open, and the contact area between the barb structure of the head of the expansion nail and the underground is further increased, so that the expansion nail is firmly inserted into the ground.

[0044] Furthermore, for a thicker expanding core, a double-body configuration can be adopted, that is, the head and tail of the expanding core are made of different materials, the head of the expanding core is equipped with corrosion-resistant material, and the tail of the expanding core is equipped with cheap smash-resistant material, which can effectively save costs.

[0045] In one example, a serpentine groove is provided on the side wall of the sleeve, and the serpentine groove penetrates the side wall of the sleeve along the axial direction of the sleeve, and the optical fiber can be installed in the sleeve through the serpentine groove.

[0046] Specifically, the material of the sleeve is preferably anti-corrosion material. In actual applications, since there is often sewage in roadside drainage ditches, the sewage will corrode the sleeve, thereby affecting the service life of the sleeve. Therefore, the use of anti-corrosion material can slow down the corrosion effect of sewage on the sleeve and extend the service life of the sleeve.

[0047] Furthermore, the side wall of the sleeve is provided with a serpentine groove, so that the optical fiber can be installed in the sleeve from the side without damaging the optical fiber, thereby reducing the loss of the optical fiber during the construction process and saving costs.

[0048] In one example, a pair of protective caps are further included, and the pair of protective caps are respectively covered at two ends of the sleeve; the protective caps are provided with through holes allowing the optical fiber to pass through;

[0049] The protective cap is also provided with a side seam for installing the optical fiber.

[0050] Specifically, in practical applications, optical fibers are usually very long, and therefore multiple fast optical fiber wiring devices are required. The protective caps at both ends can prevent friction damage between the optical fiber and the sleeve during use, thereby effectively protecting the optical fiber near the sleeve. At the same time, the protective cap is also provided with side seams, and the optical fiber can be installed from the side, thereby avoiding damage to the optical fiber caused by the perforation operation, increasing the service life of the optical fiber, and effectively saving costs in the long run.

[0051] In one example, the clamp is an elastic clamp; the clamp is C-shaped, and the axial direction of the clamp is substantially perpendicular to the axial direction of the expansion nail.

[0052] Specifically, the clamp is a C-shaped elastic clamp. First, the C-shape can increase the contact area between the clamp and the sleeve, thereby increasing the stability of the sleeve. At the same time, the elastic clamp is convenient for the sleeve to be installed on the clamp, and after the installation is completed, the clamp and the sleeve fit tightly together, further increasing the stability of the connection between the sleeve and the expansion pin. When troubleshooting or changing the optical fiber line, the sleeve containing the optical fiber can be flexibly taken out for troubleshooting or line changes.

Preferably, the clamping head 2 is designed to be C-shaped, and the axial direction of the clamping head 2 is basically perpendicular to the axial direction of the expansion nail 1; the head of the expansion nail 1 is conical, and the outer surface of the head is provided with a barb structure 5. The head of the expansion nail 1 is provided with a plurality of slits 8 arranged along the axial direction.

[0055] like Figure 2 As shown, a blind hole 6 arranged axially is provided in the expansion nail 1, and the blind hole 6 extends from the end face of the tail of the expansion nail 1 to the head of the expansion nail 1; the fast optical fiber wiring device also includes an expansion core 4, the length of the expansion core 4 is greater than the length of the blind hole 6, and can be inserted into the blind hole 6; the closed end of the blind hole 6 is conical, and one end of the expansion core 4 is a cone that cooperates with the closed end of the blind hole 6.

The protective caps are provided with through holes (not shown) for allowing the optical fiber to pass through, and the protective caps are also provided with side seams (not shown) for installing the optical fiber. The protective caps can avoid friction damage between the optical fiber and the sleeve 3, thereby effectively protecting the optical fiber near the sleeve 3.

[0057] The installation process of the fast optical fiber wiring device of this embodiment is as follows:

[0058] S1. Use a hammer to hammer the expansion nail 1 into the ground, ensure that the clamp head 2 is exposed above the ground, and ensure that the sleeve 3 is in the correct direction during installation.

[0059] S2. Insert the expansion core 4 into the expansion nail 1 and hammer it in with a hammer.

[0060] S3. Shake the expansion nail 1 as a whole to determine the stability of the installation.

[0061] S4. Install the optical fiber in the sleeve 3. Install protective caps at both ends of the sleeve 3 to prevent the optical fiber from being damaged due to reciprocating friction.

[0062] S5. Insert the sleeve 3 into the clamping head 2 of the expansion nail.

[0063] S6. Pull the optical fiber so that it adheres to the ground surface, and the installation is completed.

[0064] To sum up, in actual application, the expansion nail is hammered into the ground with a hammer and the clamp is exposed on the surface. The optical fiber is installed in the sleeve. The sleeve is firmly connected to the expansion nail through the clamp. The optical fiber is stably fixed close to the ground surface.
