Description

Technical Field

[0001] This utility model relates to the field of indoor optical cable technology, specifically a convenient cable laying device for indoor optical cables. Background Technology

[0002] Indoor optical fiber cables are optical cables laid within buildings, primarily used for communication equipment, computers, switches, and end-user devices within the building to transmit information. Before use, indoor optical fiber cables are typically in coil form, and are released through a cable-laying device for use by staff.

[0003] Existing cable laying devices typically secure the cable by knotting the tail end with the wound cable after winding it up. For thinner or smooth-surfaced indoor cables, the knotting process is prone to slipping, requiring repeated adjustments to secure it firmly, which increases the finishing time after winding. Untying the knot before the next use also takes time, and if the knot is too tight and forms a dead knot, it may even require tools to untie, seriously affecting the efficiency of construction or use. To address this problem, we propose a convenient cable laying device for indoor optical cables. Utility Model Content

[0004] The purpose of this invention is to provide a convenient cable laying device for indoor optical cables to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient cable laying device for indoor optical cables, comprising a cable laying frame, the side of which is rotatably connected to a turntable, the turntable being fixedly connected to the side of a drum, the drum being rotatably connected to the inner wall of the cable laying frame, one end of the optical cable being wound around the outer wall of the drum, and the other end of the optical cable being wound around the side of a fixing block, the fixing block having a locking hole, a fixing plate being fixedly installed on the inner wall of the cable laying frame, the fixing plate having a guide hole, and a control component and a driven component being disposed within the fixing plate, the control component including: A clamping rod is provided, which passes through and slidably connects to a fixing plate. A crossbar is fixedly installed on the inner wall of the fixing plate, and the crossbar passes through and slidably connects to the clamping rod. One side of the clamping rod is fixedly connected to one end of a spring, and the other end of the spring is fixedly installed on the outer wall of the crossbar. A moving block is fixedly installed on the side of the clamping rod. Fixing components for fixing the clamping rod are provided inside the moving block and on the inner wall of the fixing plate, thereby limiting the springing of the moving block and the clamping rod, fixing the wound optical cable, and avoiding the inconvenience of manual knotting.

[0006] Preferably, the fixing component includes a slider with a trapezoidal cross-section and a vertical rod inside the slider. The vertical rod passes through the slider and is slidably connected to it. The vertical rod ensures the stability of the slider during longitudinal movement.

[0007] Preferably, the top of the slider is fixedly connected to one end of the second spring, the other end of the second spring is fixedly installed on the outer wall of the vertical rod, the vertical rod is fixedly installed at the bottom of the round rod, and when the cut surface of the slider is no longer in contact, it can bounce off the surface of the vertical rod under the action of the second spring.

[0008] Preferably, the round rod passes through the moving block and is rotatably connected to the moving block. A round plate is fixedly installed on the top of the round rod, and a slot is provided on the outer side of the round plate. The slot on the side of the round plate can restrict the rotation of the round plate and the round rod.

[0009] Preferably, a rotating rod is fixedly installed on the top of the circular plate. The rotating rod passes through the moving block and is rotatably connected to the moving block. When the rotating rod is subjected to force, it can drive the circular plate to rotate within the moving block.

[0010] Preferably, a protrusion is fixedly installed on the inner side of the fixing plate, and the inner side of the fixing plate is in contact with the back of the moving block. When the protrusion abuts against the cut surface of the slider, it can make it rise longitudinally.

[0011] Preferably, the driven component includes a spring three, one end of which is fixedly installed on the side of the limiting rod, and the other end of which is fixedly installed on the inner wall of the moving block. A flat rod is fixedly installed on the inner wall of the moving block. The flat rod passes through the limiting rod and is slidably connected to the limiting rod. When the limiting rod is no longer subjected to the pushing force, it can spring up from inside the flat rod under the action of the spring three.

[0012] Compared with the prior art, this utility model provides a convenient cable laying device for indoor optical cables, which has the following beneficial effects: 1. This convenient indoor optical cable laying device, equipped with a control component, allows the fixed block to fit against the side of the fixed plate after the optical cable is wound up by the drum. By pushing the moving block, the locking rod fixed on the surface of the moving block moves along the surface of the crossbar and engages in the locking hole opened in the fixed block. When the protrusion abuts against the tangent of the slider, the slider can move longitudinally under force. When the protrusion no longer abuts against the tangent of the slider, the slider can spring up under the action of the second spring, thereby limiting the springing of the moving block and the locking rod, and fixing the wound optical cable, avoiding the inconvenience of manual knotting.

[0013] 2. The convenient cable laying device for indoor optical cables is equipped with a driven component. When the tangential surface of the slider contacts the protrusion, the slider can be displaced. Therefore, when the round rod rotates, the slider connected to the vertical rod on the surface of the round rod can rotate synchronously. The surface of the round plate fixed at the top of the round rod has a slot. Therefore, when the limiting rod is in the slot, the round rod cannot rotate and the slider cannot move. This method can enhance the stability of the locking rod after it is locked into the locking hole and avoid loosening. Attached Figure Description

[0016] like Figures 1-5As shown, this utility model provides a technical solution: a convenient cable laying device for indoor optical cables, including a cable laying frame 1. The side of the cable laying frame 1 is rotatably connected to a turntable 3. The turntable 3 is fixedly connected to the side of a drum 2. The drum 2 is rotatably connected to the inner wall of the cable laying frame 1. The outer wall of the drum 2 is wound around one end of an optical cable 4, and the other end of the optical cable 4 is wound around the side of a fixing block 7. A locking hole 10 is provided in the fixing block 7. A fixing plate 5 is fixedly installed on the inner wall of the cable laying frame 1. A guide hole 6 is provided in the fixing plate 5. A control component 8 and a driven component 9 are provided in the fixing plate 5. The control component 8 includes: a locking rod 81, a crossbar 82, a spring 83, a moving block 84, and a fixing member 85. The locking rod 81 passes through the fixing plate 5 and is slidably connected to the fixing plate 5. A crossbar 82 is fixedly installed on the inner wall of the fixing plate 5. The crossbar 82 passes through the locking rod 81 and is slidably connected to the locking rod 81. The side of the locking rod 81 is fixed to one end of the spring 83. The other end of the spring 83 is fixedly installed on the outer wall of the crossbar 82. A moving block 84 is fixedly installed on the side of the clamping rod 81. The moving block 84 and the inner wall of the fixing plate 5 are provided with a fixing member 85 to fix the clamping rod 81. The moving block 84 is pushed laterally in the fixing plate 5. When the moving block 84 moves, the clamping rod 81 fixed on the surface of the moving block 84 can slide synchronously. When the clamping rod 81 moves, it can be inserted into the clamping hole 10 in the fixing block 7. During the lateral movement of the moving block 84, the protrusion 858 will abut against the cross surface of the slider 851. When the cross surface of the slider 851 is abutted, it can be lifted longitudinally. When the protrusion 858 no longer abuts against the cross surface of the slider 851, the slider 851 can bounce up under the action of the spring 853, thereby limiting the bounce of the moving block 84 and the clamping rod 81, and fixing the wound optical cable 4, avoiding the inconvenience caused by manual knotting.

[0017] The fixing component 85 includes a slider 851 with a trapezoidal cross-section. A vertical rod 852 is installed inside the slider 851, passing through and slidably connected to it. The vertical rod 852 ensures the stability of the slider 851 during longitudinal movement. The top of the slider 851 is fixedly connected to one end of a second spring 853, and the other end of the second spring 853 is fixedly installed on the outer wall of the vertical rod 852. The vertical rod 852 is fixedly installed at the bottom of a round rod 854. When the cross-section of the slider 851 is no longer in contact with the spring, it can spring up from the surface of the vertical rod 852 under the action of the second spring 853. The round rod 854 passes through and is rotatably connected to a moving block 84. A round plate 855 is fixedly installed on the top of the round rod 854. A slot 856 is provided on the outer side of the round plate 855, which restricts the rotation of the round plate 855 and the round rod 854. A rotating rod 857 is fixedly installed on the top of the circular plate 855. The rotating rod 857 passes through the moving block 84 and is rotatably connected to the moving block 84. When the rotating rod 857 is subjected to force, it can drive the circular plate 855 to rotate within the moving block 84. A protrusion 858 is fixedly installed on the inner side of the fixed plate 5. The inner side of the fixed plate 5 is in contact with the back of the moving block 84. When the protrusion 858 abuts against the tangential surface of the slider 851, it can lift the slider longitudinally. The driven component 9 includes a spring 91. One end of the spring 91 is fixedly installed on the side of the limiting rod 92, and the other end of the spring 91 is fixedly installed on the inner wall of the moving block 84. A flat rod 93 is fixedly installed on the inner wall of the moving block 84. The flat rod 93 passes through the limiting rod 92 and is slidably connected to the limiting rod 92. When the limiting rod 92 is no longer subjected to the pushing force, it can spring up from the flat rod 93 under the action of the spring 91.

[0018] In this invention, during use, one end of the optical cable 4 is inserted through the guide hole 6 on the side of the fixing plate 5 and wound around the surface of the drum 2. Then, the other end of the optical cable 4 is wound around the surface of the fixing block 7. After winding, the turntable 3 is rotated on the side of the pay-off frame 1, and the turntable 3 drives the drum 2 to rotate, and the drum 2 winds up the optical cable 4. After winding, the fixing block 7 will gradually come into contact with the side of the fixing plate 5. After contact, the moving block 84 is pushed laterally inside the fixing plate 5. When the moving block 84 moves, the locking rod 81 fixed on the surface of the moving block 84 can slide synchronously. When the locking rod 81 moves, it can be locked into the locking hole 10 in the fixing block 7. During the lateral movement of the moving block 84, the protrusion 858 will abut against the cross-section of the slider 851. When the cross-section of the slider 851 is abutted, it can be lifted longitudinally. When the protrusion 858 no longer abuts against the cross-section of the slider 851, the slider 851 can spring up under the action of the spring 853. This restricts the springback of the moving block 84 and the locking lever 81, securing the wound optical cable 4 and avoiding the inconvenience of manual knotting. When it is necessary to release the fixation, push the limiting lever 92 on the top of the moving block 84. The limiting lever 92 moves out of the slot 856 opened in the circular plate 855. After it moves out, maintain the pushing force and rotate the rotating rod 857. The rotating rod 857 drives the circular rod 854 to rotate. When the circular rod 854 rotates, the circular rod 85... 4. The vertical rod 852 fixed at the bottom can drive the slider 851 to rotate synchronously, so that the cut surface of the slider 851 fits with the surface of the protrusion 858. Then the moving block 84 can bounce up under the action of the spring 83. When the protrusion 858 abuts against the cut surface of the slider 851, it moves longitudinally. When the limiting rod 92 is in the slot 856, it can limit the rotation of the round plate 855 and the round rod 854, thereby ensuring the stability of the locking rod 81 after it is locked in.

[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
