Description

Technical Field

[0001] This utility model relates to the field of optical cable laying technology, and in particular to an integrated invisible optical cable laying gun head and its glue gun. Background Technology

[0002] With the increasing demand for networks, there is a growing need for FTTR fiber optic cables.

[0003] However, in current technology, only exposed wiring is possible for old building renovations, with adhesive bonding for securing invisible fiber optic cables being a common option. Common adhesive bonding methods for invisible fiber optic cables include spot bonding and full-coverage bonding. Full-coverage bonding requires precise technique and is difficult to apply efficiently. Spot bonding cannot fully secure the invisible fiber optic cable, making it prone to detachment.

[0004] Currently, glue guns are also used to lay invisible optical cables. However, existing glue guns are usually of a split structure, which is complex and cumbersome to install and disassemble. In addition, since the glue application channels for the optical cable are all located inside the gun head, it is not convenient to separate the optical cable from the gun head after construction is completed. Utility Model Content

[0005] The main purpose of this utility model is to provide an integrated invisible optical cable laying gun head and its glue gun, which aims to simplify the installation and disassembly process, and at the same time facilitate the separation of the optical cable and the gun head after the construction is completed.

[0006] To achieve the above objectives, this utility model provides an integrated invisible optical cable laying gun head, including a gun head body and an invisible optical cable limiting device integrally formed therewith, wherein, The gun head body is provided with a glue-feeding channel and a mixing channel connected thereto. One end of the glue-feeding channel opposite to the mixing channel is used to connect to the connection end of the glue tube. The side of the mixing channel opposite to the glue-feeding channel is open. The invisible optical cable limiting device is connected to the outer wall of the gun head body, and a cable-feeding channel for the invisible optical cable to pass through is formed between the two. The outlet of the cable-feeding channel is connected to the inlet of the mixing channel. The gun head body has a scraping nozzle connected to the outlet of the mixing channel for the invisible optical cable mixed with glue to pass through.

[0007] Preferably, the end of the gun head body opposite to the end of the tube has two guide plates protruding outward, and the outlet of the gap between the two guide plates forms the scraping nozzle.

[0008] Preferably, the guide plate extends a guide portion toward the cable channel side, and a transition channel is formed between the guide portions of the two guide plates for the invisible optical cable to pass through, and the space between the two guide plates forms the hybrid channel.

[0009] Preferably, the free end of the guide plate has an inclined structure, and the angle between the free end of the guide plate and the end face of the gun head body where the glue scraping nozzle is located is an acute angle.

[0010] Preferably, the gun head body includes a connecting part, a dispensing part, and a squeezing part that are fixedly connected in sequence. A fastening part is provided above the connecting part for fasteners to pass through so as to detachably connect the glue tube and the gun head body. The internal channels of the connecting part, the dispensing part, and the squeezing part together form the glue channel. The dispensing end of the squeezing part extends in the dispensing direction to form the guide plate.

[0011] Preferably, the glue-feeding channels inside the connecting part and the extrusion part are both channels with equal cross-sections. The cross-section of the glue-feeding channel of the dispensing part gradually decreases along the dispensing direction. The cross-sectional dimensions of the connecting part are the same as the large end cross-sectional dimensions of the glue-feeding channel of the dispensing part, and the cross-sectional dimensions of the extrusion part are the same as the small end cross-sectional dimensions of the glue-feeding channel of the dispensing part; or, the end of the extrusion part away from the dispensing part has an inclined slope structure to match the inclined structure of the guide plate.

[0012] Preferably, the invisible optical cable limiting device includes at least two buckles fixed to the outer wall of the gun head body, and the cable passage is formed between the buckles and the outer wall of the gun head body.

[0013] Preferably, the latch includes a guide arm connected to the gun head body and a pressing arm extending outward from the free end of the guide portion. All the latches are staggered on both sides in the length direction of the cable channel, and the length of the guide arm in the length direction of the cable channel is greater than the length of the pressing arm.

[0014] This utility model also proposes an integrated invisible optical cable laying glue gun, including a gun body and a glue tube mounted on the gun body, and also includes the aforementioned integrated invisible optical cable laying gun head, with the end of the gun head body of the integrated invisible optical cable laying gun head connected to the glue tube.

[0015] Preferably, the gun head body and the hose are detachably connected and the installation angle between them can be adjusted; or the gun body is equipped with an optical cable reel for placing optical cables.

[0016] The integrated invisible optical cable laying gun head proposed in this utility model has the following beneficial effects: 1.

The side wall of the adhesive scraper can scrape off the excess adhesive, ensuring the laying effect. 2. The fusion point between the adhesive channel and the invisible optical cable is on the outside of the gun head, which facilitates the separation of the invisible optical cable from the gun head after construction. 3. The gun head adopts an integrated structure, which makes its manufacturing, installation and disassembly process simpler and more convenient (if a complex split structure is adopted, its installation and disassembly are very troublesome). 4. During the construction process, the invisible optical cable is always inside the mixed channel and finally comes out from the top adhesive scraping hole, thus protecting the invisible optical cable and avoiding damage to the optical cable by pressing on it during the laying process. 5.

[0022] This utility model proposes an integrated invisible optical cable laying gun head.

[0023] Reference Figure 5 and Figure 7 In this preferred embodiment, an integrated invisible optical cable laying gun head includes a gun head body 1 and an invisible optical cable limiting device 2 integrally formed therewith, wherein... The gun head body 1 is provided with a glue-feeding channel 12 and a mixing channel 13 connected thereto. The end of the glue-feeding channel 12 facing away from the mixing channel 13 is used to connect with the connection end 61 of the glue tube 6. The side of the mixing channel 13 facing away from the glue-feeding channel 12 is open. The invisible optical cable limiting device 2 is connected to the outer wall of the gun head body 1, and the two form a cable-feeding channel 21 for the invisible optical cable 4 to pass through. The outlet of the cable-feeding channel 21 is connected to the inlet of the mixing channel 13. The gun head body 1 is provided with a scraping nozzle 11 connected to the outlet of the mixing channel 13 so that the invisible optical cable 4 mixed with glue can pass through.

[0024] Reference Figure 5 The cable routing channel 21 and the adhesive routing channel 12 are set independently. The invisible optical cable 4 enters through the cable routing channel 21 and the adhesive in the adhesive routing channel 12 is mixed in the mixing channel 13 before exiting. In this embodiment, the adhesive scraping nozzle 11 is located on the top surface of the gun head body 1, and the side wall of the adhesive scraping nozzle 11 is an arc surface to avoid scratching the invisible optical cable 4.

[0025] Specifically, in this embodiment, referring to Figure 3 and Figure 4 Two guide plates 3 protrude from the end of the gun head body 1 away from the glue tube 6 in the glue dispensing direction. The outlet between the two guide plates 3 forms the glue scraping nozzle 11 (the shape of the glue scraping nozzle 11 is formed by the design of the top surface of the gun head body 1). In other words, the outlet of the mixing channel 13 is the glue scraping nozzle 11. The guide plates 3 are integrally formed with the gun head body 1 for ease of manufacturing.

[0026] The mixing channel 13 is formed by two guide plates 3. Therefore, one side of the mixing channel 13 (the side facing the wall) is an open structure, which facilitates the adjustment of the position of the invisible optical cable 4 in special circumstances, and also facilitates the separation of the invisible optical cable 4 from the gun head after construction is completed.

[0027] Furthermore, referring to Figure 5 The guide plate 3 extends a guide section 31 towards the cable channel 21. A transition channel 18 is formed between the guide sections 31 of the two guide plates 3 for the invisible optical cable 4 to pass through. The space between the two guide plates 3 forms a mixed channel 13 (such as...). Figure 5 (As shown). The guide section 31 guides the cable routing channel into the mixing channel 13, allowing the invisible optical cable 4 to be inserted into the mixing channel 13 more accurately. The transition channel 18 formed by the guide section 31 is an arc-shaped channel to avoid scratching the invisible optical cable 4, and this structure can match the bending radius of the optical cable.

[0028] Furthermore, in conjunction with reference Figure 2 and Figure 3 The guide plate 3 has a sloping end (the end connected to the gun head body 1 is its fixed end, and the other end is the free end), which is used to abut against the wall. Figure 2 As shown, the angle between the free end of the guide plate 3 and the end face of the gun head body 1 where the glue scraping nozzle 11 is located is an acute angle (i.e., Figure 2 (α angle).

[0029] In this embodiment, by setting the free end of the guide plate 3 as a sloping structure, it is easy to fit tightly to the wall and avoid glue seepage. On the other hand, it is also easy to squeeze the invisible optical cable 4 out from the glue scraping port 11 above it during construction, ensuring the operability of laying the optical cable and making it more convenient for users to operate.

[0030] Specifically, refer to Figure 4 and Figure 5This embodiment presents a specific structure of the gun head body 1: the gun head body 1 includes a connecting part 14, a dispensing part 15, and a squeezing part 16 (all three are integrally formed) connected in sequence. A fastening part 17 protrudes from the top of the connecting part 14 to allow a fastener (such as a hand-tightening screw) to pass through, detachably connecting the glue tube 6 and the gun head body 1. The internal channels of the connecting part 14, the dispensing part 15, and the squeezing part 16 together form a glue-feeding channel 12. The dispensing end of the squeezing part 16 (referring to the glue outlet direction of the glue-feeding channel 12) extends in the dispensing direction (referring to the direction from the inlet to the outlet of the glue-feeding channel 12) to form a guide plate 3. The connecting part 14 has a cylindrical shape, the dispensing part 15 has a frustum shape, and the squeezing part 16 has an isosceles trapezoid shape. The fastening part 17 is integrally formed with the connecting part 14. A scraping nozzle 11 is provided in the area enclosed between the top surface of the squeezing part 16 and the two guide plates 3. The top surface of the extrusion section 16 and the joint of the scraper nozzle 11 serve as a scraper for adhesive.

[0031] Furthermore, in this embodiment, referring to Figure 5 The glue-feeding channels 12 inside the connecting part 14 and the extrusion part 16 are both channels with equal cross sections. The cross section of the glue-feeding channel 12 of the dispensing part 15 gradually decreases along the dispensing direction. The cross section size of the connecting part 14 is the same as the large end cross section size of the glue-feeding channel 12 of the dispensing part 15, and the cross section size of the extrusion part 16 is the same as the small end cross section size of the glue-feeding channel 12 of the dispensing part 15.

[0032] In this embodiment, by setting the glue delivery channel 12 of this shape, the stability of glue dispensing can be guaranteed.

[0033] Furthermore, in this embodiment, in conjunction with reference to... Figure 3 , Figure 5 and Figure 6 The end of the extrusion section 16 facing away from the dispensing section 15 is inclined to match the inclined structure of the guide plate 3. In other words, the dispensing end of the extrusion section 16 is parallel to the inclined surface of the guide plate 3, so that the cross section of the mixing channel 13 is similar to a parallelogram. This can stably ensure that the glue is evenly applied to the outside of the invisible optical cable 4, thereby ensuring the laying effect. On the other hand, it is also beneficial to match the bending radius of the optical cable.

[0034] In this embodiment, refer to Figure 1 and Figure 6 The invisible optical cable limiting device 2 includes at least two latches fixed to the outer wall of the gun head body 1, forming a cable passage 21 between the latches and the outer wall of the gun head body 1. By setting at least two latches to form the cable passage 21, the invisible optical cable 4 is reliably and stably limited inside the cable passage 21, preventing exposed and messy optical cables from affecting the user's operation.

[0035] Specifically, refer to Figure 6This embodiment proposes a specific structure for the latch: the latch includes a guide arm 22 connected to the gun head body 1 and a pressing arm 23 extending outward from the free end of the guide portion 31. All latches are staggered on both sides of the cable routing channel 21 along its length (i.e., distributed left and right along the length of the cable routing channel 21). The length of the guide arm 22 in the length of the cable routing channel 21 is greater than the length of the pressing arm 23. The pressing arm 23 presses the invisible optical cable 4 inside, thereby limiting the position of the invisible optical cable 4, and the guide arm 22 prevents the invisible optical cable 4 from shifting left or right.

[0036] In this embodiment, refer to Figure 2 and Figure 6 A guide plate 3 has a guide section 31 connected to its guide arm 22 near the buckle to form a whole, which facilitates the guidance of the invisible optical cable 4.

[0037] The working process of this integrated invisible optical cable laying nozzle is as follows: First, refer to Figure 7 The integrated invisible optical cable laying gun head is installed on the gun body 5. A hand-tightening screw 8 is inserted into the fastening part 17 of the gun head body 1, and then the hand-tightening screw 8 is turned to tighten it onto the connection end 61 of the hose 6. Then, refer to... Figure 6 After the invisible optical cable 4 on the optical cable reel 7 is passed through the cable channel 21 formed by the clip, it is inserted into the mixing channel 13 and finally exits through the glue scraping nozzle 11. During installation, after aligning the free ends of the two guide plates 3 with the wall, press the handle of the gun body 5 to make the glue tube 6 dispense glue, and control the gun body 5 to move along the wall from top to bottom. The invisible optical cable 4 wrapped with glue in the mixing channel 13 exits through the glue scraping nozzle 11. At the same time, the side wall of the glue scraping nozzle scrapes off the excess glue on the outside of the invisible optical cable 4. The invisible optical cable 4 with glue extends continuously along the direction of the gun body movement and is thus bonded to the wall.

[0038] The integrated invisible optical cable laying gun head proposed in this embodiment has the following beneficial effects: 1. The invisible optical cable 4 wrapped with glue is passed through the glue scraping nozzle 11 before laying. The side wall of the glue scraping nozzle 11 (the side wall refers to the side wall of the U-shaped groove formed by the two guide plates 3 and the top surface of the glue extrusion part 16) can scrape off the excess glue, ensuring the laying effect. 2. The fusion position of the adhesive channel 12 and the invisible optical cable 4 is on the outside of the gun head, and the mixing channel 13 is set with an opening facing the wall. After the construction is completed, the invisible optical cable 4 can be pulled out directly from the opening side of the mixing channel 13 (it is not necessary to pull out the invisible optical cable 4 through the inside of the gun head body 1), which makes it very convenient to separate the invisible optical cable 4 from the gun head. 3. The gun head adopts an integrated structure, which makes its manufacturing, installation and disassembly process simpler and more convenient (adopting an integrated structure, there is only one step to install the whole structure, and there is only one step to disassemble one part, without the tedious process of disassembling multiple parts). 4. During the construction process, the invisible optical cable 4 is always inside the mixing channel 13 and finally comes out from the top glue-scraping opening 11, thereby protecting the invisible optical cable 4 and avoiding damage to the optical cable by pressing it during the laying process. 5. This integrated invisible optical cable laying gun head has the advantages of simple structure and stable and reliable operation.

[0039] This utility model also proposes an integrated invisible optical cable laying glue gun.

[0040] Reference Figure 8 In this preferred embodiment, an integrated invisible optical cable laying glue gun includes a gun body 5 and a glue tube 6 mounted on the gun body 5, and also includes an integrated invisible optical cable laying gun head, the end of the gun head body of the integrated invisible optical cable laying gun head being connected to the glue tube.

[0041] In this embodiment, the end of the gun head body 1 of the integrated invisible optical cable laying gun head is sleeved on the connection end 61 of the rubber tube 6 and is detachably connected by fasteners. The installation angle of the gun head body 1 relative to the rubber tube 6 is adjustable (the installation angle is adjusted by loosening the fasteners). An optical cable reel 7 for placing the optical cable is installed on the gun body 5. (Refer to reference...) Figure 5 and Figure 8 The connecting part 14 is sealed to the gun head body 1. The specific structure and beneficial effects of the integrated invisible optical cable laying gun head are as described in the above embodiment, and will not be repeated here.

[0042] In this embodiment, by providing a fiber optic cable reel 7 on the gun body 5, the fiber optic cable can be easily integrated into one unit, eliminating the need for a separate fiber optic cable reel 7 and facilitating cable storage. The installation angle of the gun head body 1 relative to the hose 6 is adjustable, allowing users to adjust it according to the actual wall angle, thus improving the flexibility of this integrated invisible fiber optic cable laying gun.

[0043] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
