[0002] In daily life, power cables are widely used in various industries and occasions. Some of them are placed in harsh environments, such as buried underground in a humid environment, or exposed outdoors and exposed to wind and sun, etc., which greatly shorten the life of cable protection tubes; with the advancement of the times, the requirements for cable protection tubes are getting higher and higher.

[0003] In actual use, multiple cables are inserted into a protective tube. If more cables need to be added later, a certain amount of space needs to be reserved. Therefore, the cables in the original pipe are prone to shaking after being inserted. Multiple cables coexist in one protective tube. After the cables are installed, the power cables are prone to shaking in the protective tube, and the multiple cables collide with each other, increasing the chance of damage to the cables. Utility Model Content

[0004] Based on this, it is necessary to provide a cable protection tube for laying optical cables to address the problem of cables shaking easily in the protection tube, which can reduce the shaking of the cables in the protection tube and avoid damage to the cables.

[0023] like Figure 1-Figure 3 As shown,

[0024] As an optional embodiment,

[0025] A cable protection tube for laying optical cables comprises a tube body 1, wherein arc-shaped plates 2 for clamping cables are arranged on opposite sides of the tube body 1, and the two arc-shaped plates 2 are fixed to the inner wall of the tube body 1 through a telescopic member; the telescopic member comprises an arc-shaped rod 4, a first support bar 6 and a second support bar 7, one end of the first support bar 6 and the second support bar 7 are respectively hinged to the opposite side surfaces of the arc-shaped plate 2, one end of the first support bar 6 and the second support bar 7 are connected to the arc-shaped rod 4 through a first hinge seat 3, each first hinge seat 3 is slidably matched with the arc-shaped rod 4, a spring 5 is sleeved on the arc-shaped rod 4, and the spring 5 is located between the two hinges.

[0026] In order to position multiple cables, two arc plates 2 are designed to be installed inside the tube body 1. The distance between the two arc plates 2 can be adjusted later so that multiple cables inserted in the gap can be restrained together. When multiple cables need to be restrained, the arc plate 2 can be moved closer to the arc rod 4. At this time, the first support bar 6 and the second support bar 7 are respectively hinged on both sides of the arc plate 2, and the other side is connected to the first hinge seat 3 and displaced in the center on the arc rod 4, compressing the spring 5 on the arc rod 4, and then the first support bar 6 and the second support bar 7 are moved closer to each other. After the cable passes through, the external force to push the arc plate 2 can be cancelled, and the first support bar 6 and the second support bar 7 are pushed away from each other by the spring 5. The first support bar 6 and the second support bar 7 jointly push the arc plate 2 to move toward the center of the tube body 1, and make the arc plate 2 abut against the surface of the cable. The two arc plates 2 cooperate with each other to clamp multiple cables. The gap between the two arc plates 2 can be changed to reserve a certain space for the subsequent addition of cables. At the same time, the device can also buffer the up and down shaking of multiple cables, thereby improving the overall stability of the device.

[0027] Based on the first embodiment, Figure 1 As shown,

[0028] In order to further improve the clamping force, multiple support points are designed to support the arc plate 2 to improve the overall stability. The specific structure is as follows:

[0029] A third support bar 8 and a fourth support bar 9 distributed in an "eight" shape are selected to be arranged between the arc plate 2 and the arc rod 4. One end of the third support bar 8 and the fourth support bar 9 is hinged on the arc plate 2, and the other end of the third support bar 8 and the fourth support bar 9 is hinged with a second hinge seat 17. Each second hinge seat 17 is slidably matched with the arc rod 4.

[0030] As the arc plate 2 approaches the arc rod 4, the angle between the third support bar 8 and the fourth support bar 9 distributed in an "eight" shape gradually increases, and the arc plate 2 subsequently relies on the reset thrust of the spring 5 to achieve positioning of the cable.

[0031] Based on the first embodiment, Figure 1 As shown,

[0032] There are at least two springs 5 ​​, and the two springs 5 ​​are respectively sleeved on the arc rod 4 located between the first support bar 6 and the third support bar 8 , and between the fourth support bar 9 and the second support bar 7 .

[0033] Subsequently, as the arc plate 2 approaches the arc rod 4, the angle between the third support bar 8 and the fourth support bar 9 gradually increases, and the third support bar 8 and the fourth support bar 9 respectively push the springs 5 ​​on both sides to gradually move toward the two ends of the arc rod 4, and the two springs 5 ​​are respectively located between the first support bar 6 and the third support bar 8, and the fourth support bar 9 and the second support bar 7, and as the distance between the two is shortened, the spring 5 at this location is compressed, and when clamped, the spring 5 is reset, and finally the arc plate 2 positions the cable.

[0034] Based on the first embodiment, Figure 2 As shown,

[0035] Coaxial holes 21 are provided at both ends of the two arc-shaped plates 2, and positioning rods 10 are inserted into the two coaxial holes 21 on the same side. The positioning rods 10 can limit the cables between the two arc-shaped plates 2 from escaping. The coaxial holes 21 are hexagonal holes, and the corresponding positioning rods 10 are selected with hexagonal rod bodies, which can limit the rotation of the arc-shaped plates 2 on the positioning rods 10.

[0036] At the same time, in order to prevent the positioning rod 10 from being separated from the coaxial hole 21 , positioning pieces 11 are fixedly installed at both upper and lower ends of the positioning rod 10 , and the positioning pieces 11 can prevent the positioning rod 10 from sliding out of the coaxial hole 21 .

[0037] In order to reduce the vibration force in the left and right directions, the following specific structures are designed:

[0038] The middle part of the positioning rod 10 is fixedly connected to an H-shaped slider 14 through a connecting rod, and a mounting tube 12 is installed on the side of the tube body 1. A cavity 121 that slides with the H-shaped slider 14 is opened inside the mounting tube 12. When the cable shakes left and right, it drives the arc plate 2 to move left and right, prompting the positioning rod 10, the connecting rod and the H-shaped slider 14 to slide inside the mounting tube and move to one side of the inner wall of the tube body 1, and then compressing the air inside the cavity 121 to achieve the purpose of buffering, which can avoid the collision between the arc plate 2 and the inner wall of the tube body 1, and meet the buffering of the left and right shaking force on the basis of the original up and down buffering.

[0039] A seal 13 is also provided between the H-shaped slider 14 and the inner wall of the cavity 121 . The seal 13 is fixed on the H-shaped slider 14 and abuts against the inner wall of the cavity 121 . The seal 13 can reduce the gap between the H-shaped slider 14 and the inner wall of the cavity 121 .

[0040] Based on the first embodiment, Figure 3 As shown,

[0041] At least one positioning block 15 is installed on the inner side of the arc plate 2, and two positioning blocks 15 are selected as the best. At least one limit block 16 is installed on each positioning block 15, and five limit blocks 16 are designed as the best. The limit blocks 16 are all made of rubber material. The limit blocks 16 can enhance the friction of the power cable in the protective tube, avoid the power cable from shaking in the protective tube, and enhance the stability of the power cable in the protective tube.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
