[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, reference Figure 1-Figure 3 , which is the first embodiment of the present invention, and provides a communication transmission device that is easy to install, comprising: an installation unit 1, the installation unit 1 is arranged in multiple groups, and is used to be fixed on the laying object to form a laying path of the optical cable body 5, a protective cover 2 arranged on the installation unit 1, and is used to protect the device as a whole, a clamping unit 3 arranged on the installation unit 1, and is used to clamp the optical cable body 5, and a fastening connection unit 4 arranged on the installation unit 1, and is used to brake the clamping unit 3 to improve the clamping and fixing effect of the clamping unit 3 on the optical cable body 5;

[0031] The clamping unit 3 includes a movable component 31 and a clamping component 32 arranged on the mounting unit 1. The movable component 31 is used to be squeezed by the optical cable body 5 to move, thereby driving the clamping component 32 to move. The clamping component 32 is used to clamp the optical cable body 5.

[0032] The fastening connection unit 4 includes a brake block 41 arranged on the mounting unit 1, which is used to contact the clamping assembly 32 to brake the clamping assembly 32, a connecting assembly 42 arranged on the brake block 41, which is used to connect the brake blocks 41 on each group of mounting units 1, and a pulling assembly 43 arranged on the connecting assembly 42, which is used to drive the brake block 41 to move through the connecting assembly 42, and control the contact between the brake block 41 and the clamping wheel 321, thereby achieving a braking effect.

[0033] The installation unit 1 includes a base 11 for supporting the entire device, a support block 12 arranged on the base 11, two groups of support blocks 12 are arranged on the base 11, which are used to cooperate with the movable component 31 and the clamping component 32 to clamp the optical cable body 5, and a mounting hole 13 arranged on the base 11, which is used to fix the device on the laying object through the mounting hole 13, and a guide wheel 14 arranged on the support block 12, which is used to support and guide the connecting component 42 to prevent the connecting component 42 from bending and causing difficulty in pulling the brake block 41.

[0034] Among them, the base 11 is provided with card slots 111 on both sides, and the inner wall of the protective cover 2 is provided with card blocks 21 matching the card slots 111. The protective cover 2 is provided on the device and the clamped cable through the matching cover of the card blocks 21 and the card slots 111 to play a protective role.

[0035] In summary, first, the base 11 is fixed on the laying object through the mounting hole 13, and the base 11 is fixed according to the laying path. At this time, the optical cable body 5 is pressed against the movable component 31, so that the optical cable body 5 enters the clamping component 32, and the optical cable body 5 is clamped by the clamping component 32. The optical cable body 5 is clamped by multiple groups of clamping components 32 to achieve segmented clamping of the optical cable body 5, and the weight of the optical cable body 5 is shared, so that the optical cable body 5 clamped by the clamping component 32 is not easy to fall. At this time, the pulling component 43 is adjusted to drive the brake block 41 to move through the connecting component 42, and contact with the clamping component 32, and brake the clamping component 32 to prevent the clamping component 32 from rotating, thereby strengthening the clamping and fixing effect of the clamping component 32 on the optical cable body 5. Finally, after the installation is completed, the protective cover 2 is installed to the base 11 through the clamping block 21 and the clamping groove 111 to protect the entire device.

[0036] Example 2, reference Figure 1-Figure 5, which is the second embodiment of the present invention, and is different from the previous embodiment in that the optical cable body 5 is clamped. Compared with embodiment 1, further, the movable assembly 31 includes a movable block 311 arranged on the support block 12, which is used to be squeezed by the optical cable body 5 and move, the movable block 311 is arranged on the inner side of the support block 12, and the side of the movable block 311 close to each other is set as an arc surface, so that when the movable block 311 is squeezed by the optical cable body 5, a lateral component force will be generated to drive the movable block 311 to open, allowing the optical cable body 5 to enter, and the telescopic rod 312 arranged on the support block 12 plays a connecting role, the other end of the telescopic rod 312 is fixedly connected to the movable block 311, and the first telescopic spring 313 arranged on the telescopic rod 312 is used to drive the movable block 311 to return to its original position, when the movable block 311 is squeezed, the movement of the movable block 311 will squeeze the first telescopic spring 313, and after the pressure disappears, the elastic force released by the first telescopic spring 313 drives the movable block 311 to return to its original position.

[0037] The clamping assembly 32 includes a clamping wheel 321 rotatably arranged at the bottom of the movable block 311 for clamping the optical cable body 5, a sliding block 322 rotatably arranged on the clamping wheel 321 for moving along with the movement of the clamping wheel 321, a sliding groove 323 arranged on the base 11 for cooperating with the sliding block 322 for cooperating with the sliding block 322 to play a role of limited sliding, and a second telescopic spring 324 arranged between the two sets of sliding grooves 323 for pulling the clamping wheel 321 toward the middle and cooperating with the first telescopic spring 313 to drive the clamping wheel 321 to clamp the optical cable body 5;

[0038] The cross-sectional area of ​​the clamping wheel 321 gradually decreases from both ends to the middle, so that when the clamping wheel 321 rolls, it helps to adjust the optical cable body 5 to the middle position of the clamping wheel 321 to ensure the clamping effect, and at the same time decompose part of the gravity of the optical cable body 5 into lateral force, reducing the possibility of the optical cable body 5 falling during installation.

[0039] The rest of the structure is the same as that of Example 1.

[0040] In summary, after the installation unit 1 is installed, the optical cable body 5 is pressed against the arc surface on the movable block 311. At this time, the movable block 311 is subjected to the lateral component of force and drives the movable block 311 to move through the telescopic rod 312. At this time, the first telescopic spring 313 is compressed as the movable block 311 moves. At this time, the clamping wheel 321 cooperates with the movable block 311 to move, and the second telescopic spring 324 is stretched under the drive of the sliding block 322. When the optical cable body 5 passes through the movable block 311 and enters between the clamping wheels 321, the external force on the movable block 311 disappears, the first telescopic spring 313 is released, and the movable block 311 is driven to return to its original position through the telescopic rod 312. The movable block 311 drives the clamping wheel 321 to move back to the middle, and cooperates with the contraction of the second telescopic spring 324 to clamp the optical cable body 5.

[0041] Example 3, reference Figure 1-Figure 9 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the clamping wheel 321 is braked to improve the firmness of the clamping wheel 321 fixing the optical cable body 5. Compared with the first embodiment, further, two groups of brake blocks 41 are arranged on a group of support blocks 12, and a connecting shaft 411 is arranged between the two groups of brake blocks 41. The connecting shaft 411 is used to connect the two groups of brake blocks 41 into a whole, so that no matter which direction the brake blocks 41 move, the clamping wheel 321 can be braked;

[0042] The side of the brake block 41 close to the clamping wheel 321 is set to an arc shape that fits the contour of the clamping wheel 321, so that the contact area between the brake block 41 and the clamping wheel 321 can be increased, and the braking effect can be improved. The cross-sectional area of ​​the connecting component 42 gradually decreases in the direction away from the clamping wheel 321. When the clamping wheel 321 clamps optical cable bodies 5 of different diameters, the moving distances of the clamping wheel 321 are different. The brake block 41 can ensure that the maximum contact area between the brake block 41 and the clamping wheel 321 can be maintained when the clamping wheel 321 clamps optical cable bodies 5 of different diameters, thereby ensuring the braking effect of the clamping wheel 321.

[0043] A limit slider 412 is provided on the connecting assembly 42, and a limit slot 121 is provided on the supporting block 12 to cooperate with the limit slider 412. The limit slider 412 and the limit slot 121 cooperate to enable the brake block 41 to slide back and forth on the supporting block 12 to control the contact with the clamping wheel 321.

[0044] The connection assembly 42 includes a pull wire 421 disposed on the connection shaft 411 , a connection wire 422 disposed on the pull wire 421 , and a connection member 423 disposed on the connection wire 422 .

[0045] The pull wire 421 is provided with a first threaded joint 4211, abutment blocks 4212 are provided at the connection between the first threaded joint 4211 and the pull wire 421, one end of the first threaded joint 4211 is provided with an inclined surface, and a wedge block 4213 is provided on the inclined surface;

[0046] The two ends of the connecting line 422 are provided with second threaded joints 4221 that match the first threaded joint 4211. The threads of the abutment block 4212 and the second threaded joint 4221 are connected end to end. The second threaded joint 4221 is provided with a wedge-shaped groove 4222 that matches the wedge-shaped block 4213. The wedge-shaped groove 4222 does not penetrate the wedge-shaped groove 4222. The wedge-shaped groove 4222 and the wedge-shaped block 4213 are slidably connected. When the connecting line 422 is pulled, the wedge-shaped block 4213 abuts against the inner wall of the wedge-shaped groove 4222, and the matching inclined surface plays a role in strengthening the connection.

[0047] The connecting member 423 is provided with a connecting thread 4231 to cooperate with the second threaded joint 4221 and the first threaded joint 4211, and is used to rotate the first threaded joint 4211 and the second threaded joint 4221 to connect the connecting thread 4231 through threads, so as to connect the first threaded joint 4211 and the second threaded joint 4221 as a whole. When the connecting member 423 is rotated into place on the first threaded joint 4211, the connecting member 423 contacts the abutment block 4212, and the abutment block 4212 is squeezed by the connecting member 423 to produce deformation.

[0048] Among them, the pulling component 43 includes a connecting plate 431 arranged on the supporting blocks 12 at both ends, which plays a supporting role, a winding shaft 432 arranged on the connecting plate 431, which is used to connect the pulling wire 421 and rotate to retract and release the pulling wire 421. The pulling wires 421 at both ends are wound on the winding shaft 432, and the winding directions of the pulling wires 421 on the same side of the winding shaft 432 are opposite. When the winding shaft 432 is enabled to drive the pulling wire 421 to pull the brake block 41 back and forth, the clamping wheel 321 is braked, and the rotating joint 433 arranged on the winding shaft 432 controls the rotation of the winding shaft 432, and the linkage part 434 arranged on the winding shaft 432 is used to drive the winding shafts 432 on both sides to move synchronously, thereby reducing the difficulty of operation and improving the convenience of installation.

[0049] The linkage member 434 includes a first transmission wheel 4341 disposed on one set of winding shafts 432, a second rotating wheel 4342 disposed on another set of winding shafts 432, an intermediate wheel 4343 disposed on the base 11 in opposite directions to the first transmission wheel 4341 and the second rotating wheel 4342, and a transmission belt 4344 disposed on the two sets of intermediate wheels 4343. The rotating joint 433 on one side drives the first transmission wheel 4341 or the second rotating wheel 4342 to rotate through the winding shaft 432. The first transmission wheel 4341 or the second rotating wheel 4342 drives the intermediate wheel 4343 to rotate, and drives the second rotating wheel 4342 or the first transmission wheel 4341 on the other side to rotate through the transmission belt 4344. Since the directions of the first transmission wheel 4341 and the second rotating wheel 4342 are opposite, the rotation directions of the two groups of winding shafts 432 on the same side are opposite. In conjunction with the winding direction of the pull wire 421 on the winding shaft 433, it is possible to rotate one group of rotating joints 433 and drive the two groups of pull wires 421 to pull the brake block 41 synchronously.

[0050] The rest of the structure is the same as that of Example 2.

[0051] In summary, when the base 11 is installed on the laying object according to the laying route, the connecting wire 422 and the pulling wire 421 are preliminarily connected through the cooperation of the wedge block 4213 and the abutting block 4212. At this time, the connecting member 423 is rotated until the connecting member 423 abuts against the abutting block 4212 and cannot be rotated. At this time, the connection between the brake blocks 41 on the same side of the adjacent support blocks 12 is completed, ensuring that when the pulling wire 421 is pulled, the brake block 41 on one side can be driven to move synchronously to brake the clamping wheel 321;

[0052] At this time, the optical cable body 5 is laid through the clamping unit 3. When all the clamping wheels 321 have completed clamping the optical cable body 5, the position of the clamping wheels 321 clamping the optical cable body 5 can be adjusted by pulling the optical cable body 5 forward and backward, so that the optical cable body 5 can keep in contact with the same part of the clamping wheels 321 as much as possible. At this time, one set of rotating joints 433 is rotated to drive the corresponding winding shaft 432 to rotate. The winding shaft 432 rotates to make the pull wire 421 wind around the winding shaft 432, and the brake block 41 is pulled. At the same time, the winding shaft 432 rotates to drive the first transmission wheel 4341 Or the second rotating wheel 4342 rotates under the action of the intermediate wheel 4343 and the transmission belt 4344, driving the second rotating wheel 4342 or the first transmission wheel 4341 on the other winding shaft 432 on the same side to rotate synchronously, and the brake block 41 on the other side is synchronously pulled by the pull wire 421 until the brake block 41 is fully in contact with the clamping wheel 321, at which time the winding shaft 432 cannot continue to rotate, and all the brake blocks 41 have braked the clamping wheel 321, and the optical cable body 5 cannot be pulled at this time, and the position of the optical cable body 5 is fixed;

[0053] When the cable needs to be adjusted or replaced, it is only necessary to remove the protective cover 2, loosen the winding shaft 432 on the winding side, and rotate the rotating joint 433 at the other end to drive the brake block 41 to leave the contact with the clamping wheel 321. At this time, the optical cable can be quickly adjusted or replaced.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
