Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, and in particular to a cable fixing device. Background Technology

[0002] With the development of communication and power transmission technologies, the requirements for fixing cables (especially optical cables) are becoming increasingly complex. In building and communication engineering, optical cables often need to be pre-buried in walls or the ground to achieve concealed installation.

[0003] However, existing pre-buried optical cables are easily affected by construction disturbances after pre-buried, which can easily cause axial loosening and displacement. This axial loosening can lead to wear and tear on the optical cable within the pre-buried channel. Sometimes, when the optical cable is severely worn after pre-buried, destructive excavation is required for readjustment, which greatly increases the later maintenance costs. Therefore, improvements are urgently needed. Utility Model Content

[0004] The main purpose of this utility model is to propose a cable fixing device to solve the problem of wear caused by axial displacement of optical cables after pre-embedding in related technologies.

[0005] To achieve the above objectives, this utility model proposes a cable fixing device, which includes:

[0006] The tube body has a cable cavity for accommodating cables to pass through, and the outer peripheral wall of the tube body is provided with a plurality of mounting grooves, each mounting groove being spaced apart along the circumference of the tube body and extending along the length of the tube body.

[0009] In some embodiments, the claw has an extension section and a connecting section. The rotation center of the claw is rotatably mounted in the mounting groove and is located between the extension section and the connecting section. The extension section and the connecting section are set at an angle. The connecting section is connected to the drive assembly. Under the drive of the drive assembly, the connecting section causes the claw to rotate so that the extension section extends out of or retracts into the groove of the mounting groove.

[0011] In some embodiments, the drive assembly includes a rotating ring and a plurality of drive ropes. The rotating ring is rotatably mounted on one side of the tube along its length. One end of each drive rope extends into the mounting groove and is connected to the connecting section of each claw member in the mounting groove. The other end of each drive rope is connected to the rotating ring. The rotating ring rotates and pulls the drive ropes.

[0012] In some embodiments, each of the mounting slots has a through hole at one end where the rotating ring is located, and each of the transmission ropes extends from the corresponding through hole into the corresponding mounting slot.

[0013] In some embodiments, the rotating ring body is provided with a plurality of grooves in the thickness direction, each groove corresponding to each through hole, and one end of each transmission rope connected to the rotating ring body extends into the groove and is fixed in the groove.

[0028] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. In addition, the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0029] To address the technical deficiencies in related technologies, this utility model provides a cable fixing device. Please refer to [link / reference]. Figures 1 to 4 The cable fixing device includes: a tube body 100, multiple sets of claws 200, and a drive assembly 300. The tube body 100 has a cable cavity 130 for accommodating cables. The outer peripheral wall of the tube body 100 is provided with multiple mounting slots 110. Each mounting slot 110 is spaced apart along the circumference of the tube body 100 and extends along the length of the tube body 100. The number of mounting slots 110 can be three, four, or more. The number of mounting slots 110 is not specifically limited here.

[0030] It should be noted that the connection between the tube body 100 and the cable can be fixed. For example, the tube body 100 can be fixedly sleeved on the cable by filling adhesive between the tube body 100 and the cable, or the tube body 100 can be fixedly sleeved on the cable by secondary molding. The tube body 100 can also be fixedly sleeved on the cable in other ways, which will not be listed here.

[0031] Furthermore, each set of claws 200 is located in a corresponding mounting slot 110. The claw set 200 includes multiple claw components 210. Each claw component 210 is spaced apart along the length of the tube body 100. Each claw component 210 is rotatably mounted in the mounting slot 110 and has an unfolded state that is at least partially exposed at the opening of the mounting slot 110 and a retracted state that is stored in the slot of the mounting slot 110. The drive assembly 300 is disposed on the tube body 100 and can drive each claw component 210 to switch between the retracted state and the unfolded state.

[0032] With this setup, after the tube body 100 is fitted onto the outside of the cable and pre-embedded, it can act on the drive component 300, causing the drive component 300 to drive each claw component 210 to extend from the slot of the mounting groove 110 and engage with the inner wall of the pre-embedded channel. Due to the engagement of the claw components 210, the tube body 100 can be relatively fixed in the pre-embedded channel, avoiding displacement and wear during construction and ensuring reliable and secure fiber optic cable burial.

[0033] For details, please refer to Figures 4 to 6 The claw component 210 has an extension section 211 and a connecting section 212. The rotation center of the claw component 210 is rotatably installed in the mounting groove 110 and is located between the extension section 211 and the connecting section 212. In this embodiment, a rotating hole is provided on the groove wall of the mounting groove 110, and a rotating shaft 213 that rotatably engages with the rotating hole is provided at the rotation center of the claw component 210.

[0034] Furthermore, the protruding section 211 of the claw member 210 is set at an angle to the connecting section 212, and the connecting section 212 is connected to the drive assembly 300. Thus, under the drive of the drive assembly 300, the connecting section 212 causes the claw member 210 to rotate, so that the protruding section 211 extends or retracts into the slot of the mounting groove 110. In this way, when the drive assembly 300 drives the claw member 210 to rotate, since the protruding section 211 of the claw member 210 is at an angle to the connecting section 212, and the rotation center of the claw member 210 is located between the protruding section 211 and the connecting section 212, the torque distribution can be optimized to ensure that the operation of the claw member 210 is smooth and reliable. In addition, the length of the protruding section 211 is greater than the length of the connecting section 212, which can expand the deployment range and enhance the clamping force of the pipe body 100 on the pre-embedded channel.

[0035] In this embodiment, the drive assembly 300 includes a rotating ring 310 and multiple transmission ropes 320. The rotating ring 310 is rotatably mounted on one side of the tube 100 along its length. One end of each transmission rope 320 extends into the mounting groove 110 and is connected to the connecting section 212 of each claw 210 in the mounting groove 110. The other end of each transmission rope 320 is connected to the rotating ring 310. The rotating ring 310 rotates and pulls the transmission ropes 320.

[0036] With this configuration, after the pipe body 100 is pre-embedded, the rotating ring 310 can be rotated to pull each transmission rope 320, causing each transmission rope 320 to move along the length of the pipe body 100 towards the rotating ring 310. At this time, since the connecting section 212 of each claw 210 is connected to the transmission rope 320, the connecting section 212 will move under the drive of the transmission rope 320 to drive the claw 210 to rotate, and cause the protruding section 211 to extend from the slot of the mounting groove 110 and engage with the pre-embedded channel, thereby achieving the pre-fixation of the pipe body 100 in the pre-embedded channel.

[0037] In order to facilitate the transmission rope 320 to extend into the mounting groove 110 and connect with each claw 210, in this embodiment, each mounting groove 110 is provided with a through hole 120 at one end where the rotating ring 310 is provided, and each transmission rope 320 extends into the corresponding mounting groove 110 from the corresponding through hole 120.

[0038] Furthermore, in this embodiment, the rotating ring 310 has multiple grooves 311 along its thickness direction, each groove 311 corresponding to a through hole 120. One end of each transmission rope 320 connected to the rotating ring 310 extends into the groove 311 and is fixed within it. This prevents the transmission rope 320 from protruding from the surface of the tube 100, thus avoiding wear on the transmission rope 320.

[0039] Considering that the rotating ring 310 requires a certain rotational force and maintaining force to ensure that the transmission rope 320 can be pulled and the claw parts 210 can be driven to rotate, in this embodiment, the inner peripheral wall of the rotating ring 310 is provided with an internal thread, and the tube body 100 is provided with an external thread that matches the internal thread at the position corresponding to the rotating ring 310; in addition, the outer peripheral wall of the rotating ring 310 is also provided with a threaded hole 312, each threaded hole 312 corresponds to each groove 311 and passes through the rotating ring 310, and the drive assembly 300 also includes a plurality of screws 330, each screw 330 is threadedly connected to each threaded hole 312, and the part of the screw 330 located in the groove 311 is connected to the transmission rope 320. With this configuration, the rotating ring 310 is connected to the pipe 100 via a threaded connection, which increases the pulling force on the transmission rope 320 and the contact force between the claw 210 and the inner wall of the pre-embedded channel. This allows the protruding section 211 of the claw 210 to partially embed into the inner wall of the pre-embedded channel, thereby ensuring that the pipe 100 will not shift within the pre-embedded channel. Furthermore, since multiple screws 330 are provided, each screw 330 extends into a corresponding groove 311, allowing connection with the transmission rope 320 extending into the groove 311. For example, the end of the transmission rope 320 is self-wound to form a collar, which is sleeved on the outer periphery of the screw 330. Since the threaded hole 312 passes through the rotating ring 310, the tail of the screw 330, which is threaded to the threaded hole 312, can also abut against the outer periphery of the tube 100. This makes the rotating ring 310 relatively fixed on the tube 100 after rotation, preventing the transmission rope 320 from loosening due to the loosening and rotation of the rotating ring 310. This ensures that the protruding section 211 of the claw 210 protruding from the mounting groove 110 is stably engaged with the pre-embedded channel.

[0040] In addition, to facilitate the rotation of the rotating ring 310 by construction personnel, in this embodiment, the outer peripheral wall of the rotating ring 310 is covered with an anti-slip surface 313, which increases the friction and makes it easier for construction personnel to apply torque to the rotating ring 310.

[0041] This utility model also provides an optical cable, which includes a cable body 400 and a cable fixing device, the cable fixing device being sleeved on the cable body 400. It should be noted that the specific structure of the cable fixing device is the same as described in the above embodiments. Since the optical cable adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0042] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
