Description

Technical Field

[0001] This application relates to the field of optical cable fixing technology, specifically a drop optical cable fixing device. Background Technology

[0002] Drop cable is a type of optical cable that uses optical fiber with a small bending radius as the transmission medium and a bend-resistant drop cable as the outer sheath. It combines the excellent transmission performance of optical fiber with the flexibility and durability of drop cable, making it suitable for scenarios that require frequent bending or wiring in confined spaces. It is one of the important infrastructures for achieving high-speed and stable data transmission. Drop cable fixing device is a special device used to fix drop cable. It usually includes a box body and a box cover. The box body is designed with clamping parts that can clamp and fix the drop cable.

[0003] However, in existing fiber optic cable fixing devices, it has been found that during use, the fiber optic cable needs to be clipped into a pre-drilled slot, and then a cover plate is installed on top to close the slot opening, thus enabling the installation of the fiber optic cable. However, the cover plate is usually fixed to the mounting bracket below with bolts or screws. During installation or when the fiber optic cable is inspected or replaced, specific tools are required to install and remove the cover plate. The operation process is cumbersome and cannot be installed by hand, resulting in excessively long installation time and affecting installation efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a drop cable fixing device that enables manual installation via snap-fit ​​connection, saving installation time and improving installation efficiency. This solves the problem that existing technologies typically use bolts or screws for connection, requiring specific tools, resulting in cumbersome operation, making manual installation impossible, and causing excessively long installation times and affecting installation efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a drop cable fixing device, comprising a mounting base plate and a cover plate, wherein two fixing blocks are fixedly connected to the bottom surface of the cover plate, and a spring is fixedly connected to the bottom surface of each fixing block; mounting posts arranged at equal intervals are fixedly connected to the upper surface of the mounting base plate, each mounting post having an internal cavity; a locking block is slidably connected to the inner wall of each cavity; a spring is fixedly connected to the side of each locking block that is close to each other; the end of each spring that is close to each other is fixedly connected to the inner side wall of the corresponding cavity; an inclined block is slidably connected to the inner wall of each cavity; a spring is fixedly connected to the bottom surface of each inclined block; and the bottom end of each spring is fixedly connected to the inner bottom wall of the corresponding cavity.

[0006] The above solution enables rapid installation and removal of drop optical cables, eliminating the need for bolt-fixed connections and employing snap-fit ​​connections. This tool-free installation saves time and improves efficiency. Four mounting posts are installed on the upper surface of the mounting base, with cavities created inside each post. Clips are placed within these cavities for sliding connections. An inclined block is positioned below each clip, allowing it to move. During installation, a cover plate is pressed between the four mounting posts, its edge contacting the inclined surface of the clip to move it. Spring 2 is stretched until the cover plate is in place. Under the action of spring 2, the locking block is reset and the cover plate is locked, achieving quick locking of the cover plate. When disassembly is required, the inclined block is pulled upward, which stretches spring 3. Through the bottom surface of the inclined block and the bottom arc surface of the locking block, the locking block moves and spring 2 is stretched again. At this time, the locking block releases the limiting effect on the cover plate. Through the fixing block on the bottom surface of the cover plate and spring 1, the cover plate can be popped out, achieving quick disassembly. This device allows for the fixation of the optical cable components installed below by simply pressing the cover plate or pulling the inclined block during installation and disassembly, saving installation time and improving installation efficiency.

[0007] Furthermore, two mounting brackets are provided below the cover plate, and the bottom end of each spring is in contact with the upper surface of the corresponding mounting bracket.

[0008] With the above scheme, the mounting bracket is placed below the cover plate, and the bottom ends of the two springs are in contact with the upper surface of the mounting bracket. When the cover plate is installed, the bottom ends of the springs are in contact with the mounting bracket and can be compressed. When the limit on the cover plate is released, the springs rebound, allowing the cover plate to be ejected.

[0009] Furthermore, a guide rod is fixedly connected to the inner wall of each cavity, and the outer surface of each guide rod is slidably connected to the inner wall of the corresponding block.

[0010] The above solution involves installing the guide rod on the inner wall of the cavity and fixing it in place. The surface of the guide rod is connected to the corresponding locking block. Through the sliding connection between the guide rod and the locking block, the locking block can be limited, ensuring the stability of the locking block during movement.

[0011] Furthermore, two limiting posts are fixedly connected to the upper surface of the mounting base plate, and the bottom surface of the mounting base plate is coated with a nail-free adhesive layer.

[0012] The above method fixes the limiting post to the upper surface of the mounting base plate, thus enabling the installation of the limiting post. The nail-free adhesive layer is placed on the bottom surface of the mounting base plate. The nail-free adhesive layer makes it easy to fix the mounting base plate and mounting components to the wall where they need to be installed without drilling holes in the wall, achieving hole-free installation, preventing damage to the wall surface, and saving drilling time.

[0013] Furthermore, the inner wall of each mounting bracket is slidably connected to the outer surface of the corresponding limiting post, and the outer surface of each limiting post is slidably connected to the inner wall of the corresponding fixing block and cover plate.

[0014] The above scheme connects the inner walls of both sides of the mounting frame to the corresponding limiting posts, setting them as sliding connections to limit the mounting frame. Similarly, the inner walls of the fixing block and the cover plate are connected to the limiting posts, setting them as sliding connections. The limiting posts enable the positioning and installation of the mounting frame and the cover plate. With two layers of mounting frames, more drop optical cables can be fixed and clamped on the same fixing device.

[0015] Furthermore, each of the mounting brackets has equally spaced slots on its upper surface, and two semi-circular blocks are fixedly connected to the inner sidewall of each slot.

[0016] The above solution involves creating a slot on the upper surface of the mounting bracket to position the slot. The slot can limit the movement of the drop cable. Furthermore, a semi-circular block is placed on the inner wall of the corresponding slot to limit the movement of the drop cable inside the slot and prevent it from coming loose.

[0017] Furthermore, the semicircular block is made of rubber.

[0018] The above solution uses rubber as the material for the semicircular block, which has a certain degree of elasticity and is anti-slip and wear-resistant. The semicircular block can limit the installation of the drop cable and prevent the cable from coming out of the slot.

[0019] Furthermore, two connecting parts are fixedly connected to the left and right sides of the mounting base plate, and a suction cup is fixedly installed on the inner wall of each connecting part.

[0020] With the above solution, the connecting parts are set on the left and right sides of the mounting base plate and fixed. The suction cups are installed inside the corresponding connecting parts. The mounting base plate can be fixed in the required installation position in advance by the suction cups, and the suction cups provide support during the curing time of the nail-free adhesive layer.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This fiber optic cable fixing device comprises a spring, a locking block, a wedge block, and a spring. After the fiber optic cable and installation components are installed, the movable cover plate contacts the inclined surface of the locking block through its edge, causing the locking block to stretch the spring. After the cover plate is in place, the spring causes the locking block to reset. During disassembly, the wedge block is lifted, and the surface of the wedge block contacts the arc surface at the bottom of the locking block, causing the locking block to move and releasing the limiting position on the cover plate. Under the action of the spring, the cover plate pops out, enabling the device to quickly install and remove the cover plate, thereby achieving rapid installation and removal of the fiber optic cable and installation components below, saving installation time and improving installation efficiency. By setting a nail-free adhesive layer on the bottom surface of the mounting base plate and installing it with a suction cup through the connecting part, the mounting base plate is fixed by the suction cup during fixing, allowing the nail-free adhesive layer to adhere to the wall. The suction cup provides time for the nail-free adhesive layer to cure, eliminating the need to drill holes in the wall, achieving hole-free installation, preventing wall damage and saving drilling time.

[0034] Please see Figure 1 , Figure 3 and Figure 5 Two limiting posts 13 are fixedly connected to the upper surface of the mounting base plate 11. The bottom surface of the mounting base plate 11 is coated with a nail-free adhesive layer 16. The limiting posts 13 are fixed to the upper surface of the mounting base plate 11 to achieve the installation of the limiting posts 13. The nail-free adhesive layer 16 is placed on the bottom surface of the mounting base plate 11. The nail-free adhesive layer 16 makes it easy to fix the mounting base plate 11 and the mounting components to the wall where they need to be installed without drilling holes in the wall, achieving hole-free installation, preventing damage to the wall surface and saving drilling time.

[0035] Please see Figure 4 and Figure 5The inner wall of each mounting bracket 10 is slidably connected to the outer surface of the corresponding limiting post 13, and the outer surface of each limiting post 13 is slidably connected to the inner wall of the corresponding fixing block 3 and cover plate 2. The inner walls on both sides of the mounting bracket 10 are connected to the corresponding limiting post 13 in a sliding connection to limit the mounting bracket 10. The inner walls of the fixing block 3 and cover plate 2 are also connected to the limiting post 13 in a sliding connection to position the mounting bracket 10 and cover plate 2. The two layers of mounting brackets 10 can be used to fix and clamp more drop optical cables on the same fixing device.

[0036] Please see Figure 2 and Figure 4 Each mounting bracket 10 has equally spaced slots 14 on its upper surface. Two semicircular blocks 15 are fixedly connected to the inner wall of each slot 14. The slots 14 are positioned on the upper surface of the mounting bracket 10. The slots 14 can limit the drop optical cable. The semicircular blocks 15 are set on the inner wall of the corresponding slots 14 to limit the drop optical cable inside the slots 14 and prevent it from loosening.

[0037] Please see Figure 2 and Figure 4 The semicircular block 15 is made of rubber, which has a certain elasticity and anti-slip and wear-resistant properties. The semicircular block 15 can limit the installation of the drop cable and prevent the cable from coming out of the slot 14.

[0038] Please see Figure 1 , Figure 2 and Figure 3 The mounting base plate 11 has two connecting parts 17 fixedly connected to its left and right sides. Each connecting part 17 has a suction cup 18 fixedly installed on its inner wall. The connecting parts 17 are set on the left and right sides of the mounting base plate 11 for fixing, and the suction cup 18 is installed inside the corresponding connecting part 17. The mounting base plate 11 can be fixed in the required installation position in advance by the suction cup 18, and the suction cup 18 provides support during the time when the nail-free adhesive layer 16 is curing.

[0039] This embodiment of a drop cable fixing device includes components such as spring 4, locking block 6, inclined block 8, and spring 9. After the optical cable and mounting components are installed, the movable cover plate 2 contacts the inclined surface of the locking block 6 through its edge, causing the locking block 6 to stretch spring 7. After the cover plate 2 is in place, spring 7 drives the locking block 6 to reset. During disassembly, the inclined block 8 is lifted, and the surface of the inclined block 8 contacts the arc surface at the bottom of the locking block 6, causing the locking block 6 to move and release the restriction on the cover plate 2. Under the action of spring 4, the cover plate 2 springs back. This device enables the rapid installation and removal of the cover plate 2, thereby facilitating the quick installation and removal of the optical cable and installation components below, saving installation time and improving installation efficiency. By setting a nail-free adhesive layer 16 on the bottom surface of the mounting base plate 11 and installing the suction cup 18 through the connecting part 17, the mounting base plate 11 is fixed by the suction cup 18 during fixing, so that the nail-free adhesive layer 16 adheres to the wall. The suction cup 18 provides time for the nail-free adhesive layer 16 to cure, eliminating the need to drill holes in the wall, achieving hole-free installation, preventing damage to the wall surface and saving drilling time.

[0040] It should be noted that the locking block 6 slides horizontally inside the cavity 5, while the inclined block 8 slides vertically inside the cavity 5. During installation, the optical cable is pressed into the locking slot 14, and the optical cable can be limited by the semi-circular block 15.

[0041] The working principle of the above embodiments is as follows:

[0042] First, press the fiber optic cable into the corresponding slot 14, and limit it with the semi-circular block 15. Then, connect the mounting bracket 10 to the limiting post 13, stack the mounting brackets 10, and then move the cover plate 2. The edge of the cover plate 2 contacts the inclined surface of the locking block 6, causing the locking block 6 to move. At this time, the second spring 7 is stretched. Then, under the action of the fixing block 3 and the upper mounting bracket 10, the first spring 4 is compressed. After the cover plate 2 is installed in place, the locking block 6 is reset under the action of the second spring 7, which can lock the cover plate 2. Then, the mounting base plate 11 is fixed to the wall where it needs to be installed by the suction cup 18, and the nail-free adhesive layer 16 contacts the wall. The suction cup 18 is used to apply the nail-free adhesive layer 16. The curing process provides time to fix the drop cable. When the cable needs to be inspected or replaced, the inclined block 8 is pulled to stretch the spring 9. The inclined surface of the inclined block 8 contacts the arc surface at the bottom of the locking block 6, causing the locking block 6 to move. The spring 7 is stretched again, releasing the limit on the cover plate 2. The rebound of the spring 4 allows the cover plate 2 to be popped out, enabling the device to quickly install and remove the cover plate 2. This achieves the effect of quick installation and removal of the cable and mounting bracket 10, saving installation time and improving installation efficiency. Furthermore, the suction cup 18 and the nail-free adhesive layer 16 avoid drilling holes in the wall, achieving hole-free installation, preventing damage to the wall and saving drilling time.
