DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] See also Figure 1 As shown, an embodiment of the present application provides a gun head that supports the lateral insertion of an invisible optical cable, which includes a gun head body 1, wherein a fiber running channel is arranged in the gun head body 1, and the two ends of the fiber running channel respectively extend to the head and tail ends of the gun head body 1 to respectively form an optical cable entry port 2 and an optical cable exit port 3, so that the invisible optical cable 17 can enter the fiber running channel through the optical cable entry port 2 at the side of the gun head, and finally pass through the optical cable exit port 3 for laying; a glue running channel is also arranged in the gun head body 1, and one end of the glue running channel is connected to the fiber running channel, and the other end forms a connection port 5 for connecting to the glue chamber 4 of the laying gun, and the hot melt glue in the glue chamber 4 of the laying gun can enter the glue running channel from the connection port 5.

[0038] The gun head provided in the embodiment of the present application is actually similar to a three-way structure, including a fiber channel and a glue channel that are interconnected, with the two ends of the fiber channel forming an optical cable entry port 2 and an optical cable exit port 3 respectively, and one end of the glue channel forming a connection port 5. After the hot melt adhesive in the glue chamber 4 of the laying gun enters the glue channel from the connection port 5, it can continue to be squeezed into the fiber channel, thereby coating the outer surface of the invisible optical cable 17 in the fiber channel. Since the hot melt adhesive enters the fiber channel, when the invisible optical cable 17 passes through the fiber channel, it actually passes through the hot melt adhesive, which makes the outer surface of the invisible optical cable 17 fully coated, and then after coming out of the optical cable exit port 3, the invisible optical cable 17 can be fixed more firmly.

[0039] In addition, in the present application, the hot melt adhesive coating and the optical cable construction are carried out simultaneously. Compared with pre-fixing and then applying glue, the present application can improve the operation effect.

[0040] When installing invisible optical cables, the invisible optical cables are usually released through the cable pay-off drum. Since the cable pay-off drum is on the side relative to the gun head, the invisible optical cable is curved from the cable pay-off drum to the cable outlet port 3. Therefore, in order to protect the invisible optical cable and avoid bending and increasing loss of the invisible optical cable during the installation and construction process, the present application optimizes the fiber routing channel of the invisible optical cable, see Figure 1 As shown, the fiber routing channel includes a straight segment 6 and an arc segment 7 connected to each other, the optical cable entry port 2 is located on the arc segment 7, and the optical cable exit port 3 is located on the straight segment 6. The application provides the arc segment 7 so that the invisible optical cable can be routed along the arc segment 7, thereby preventing the invisible optical cable from being damaged due to excessive bending during construction.

[0041] In order to further fully coat the outer surface of the invisible optical cable 17, see Figure 1 As shown, a portion of the fiber-running channel forms a coating cavity 8, one end of the glue-running channel is connected to the coating cavity 8, and the diameter of the coating cavity 8 is larger than the diameter of the fiber-running channels at both ends of the coating cavity 8.

[0042] The diameter of part of the fiber-running channel is enlarged to form a coating cavity 8. The hot melt adhesive passing through the adhesive-running channel can fill the coating cavity 8. After the invisible optical cable 17 passes through the coating cavity 8, it can be fully coated.

[0043] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a glue outlet slope 9 is provided on the gun head body 1 at the optical cable outlet port 3. Compared with the cylindrical structure, the glue outlet slope 9 is provided, which makes it easier to press the invisible optical cable 17 at the corner during construction, thereby ensuring the convenience of construction during the installation process.

[0044] Furthermore, the fiber channel is also provided with a seal for preventing glue from flowing out of the optical cable insertion port 2. The seal can be made of common sealing materials such as foam glue. After the invisible optical cable 17 passes through, glue can be applied at the optical cable insertion port 2.

[0045] For ease of installation, see Figure 1 As shown, the connection port 5 is provided with a thread structure 10 for threaded connection with the glue cavity 4 .

[0050] In order to prevent the gun head cover 13 and the gun head base 11 from sliding in the opposite direction and disengaging, a snap-in groove or a snap-in protrusion can be set in the first slide groove, and a snap-in protrusion or a snap-in groove can be set on the first slide rail 14. When the gun head cover 13 and the gun head base 11 are installed in place, the snap-in protrusion is just snapped into the snap-in groove.

[0051] See also Figure 1 As shown, second slide rails 15 or second slide grooves are provided on both sides of the top surface of the gun head base 11 , and a second slide groove or second slide rail 15 is provided in the gun head cover 13 , and the second slide groove is adapted to the second slide rail 15 .
