Description

Technical Field

[0001] The present invention relates to the technical field of optical cable protection, in particular to a low-friction straightening optical cable protector. Background Art

[0002] An optical cable protector is a device used to protect optical cables. Usually, the optical cable protector is nested on the outside of the optical cable. The optical cable protector is responsible for bearing the external squeezing force, thereby protecting the internal optical cable.

[0003] Existing optical cable protectors for centralizing cables, such as the one disclosed in Chinese Patent Application Publication No. CN108732706A and the one disclosed in Chinese Patent Application Grant No. CN209928076U, are prone to problems when placed in underground tunnels. If the protector is too small, it will not fit tightly against the inner wall of the tunnel, affecting the stability of the optical cable. If it is too large, the friction between the protector and the inner wall of the tunnel will be too great, resulting in high resistance during deployment, making deployment difficult and affecting the efficiency of cable deployment. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide a low-friction straightening optical cable protector to solve the problem in the prior art that when the optical cable protector is placed in a channel environment such as an underground well, if the optical cable protector is too small, the fit with the inner wall of the channel is not tight enough, affecting the stability of the optical cable; if the optical cable protector is too large, the friction between the optical cable protector itself and the inner wall of the channel is too large, resulting in large resistance during the deployment of the optical cable protector and difficulty in deployment.

[0005] The purpose of the present invention can be achieved through the following technical solutions: Specifically, a low-friction straightening optical cable protector is provided, including a first protective ring and a second protective ring; and an automatic tightening mechanism located on the inner side of the second protective ring. The first protective ring and the second protective ring form a complete cylinder nested on the outer side of the optical cable sleeve. The automatic tightening mechanism tightens the position of the first protective ring after the two protective rings in the cylinder are docked with each other.

[0006] As a further solution of the present invention: the first protection ring includes a first lower arc ring and a first upper arc ring, and at least one first connecting member is fixedly connected between the first lower arc ring and the first upper arc ring.

[0007] As a further solution of the present invention: a mounting groove is provided in the middle position between the first lower arc-shaped ring and the first upper arc-shaped ring, and the automatic fastening mechanism is provided in the mounting groove.

[0008] As a further solution of the present invention: a first rotating seat and a second rotating seat are provided on both the first lower arc-shaped ring and the first upper arc-shaped ring.

[0009] As a further solution of the present invention: the second protective ring includes a second lower protective ring and a second upper protective ring, and at least a second connecting member is fixedly connected between the second lower protective ring and the second upper protective ring.

[0010] As a further solution of the present invention: the second lower protection ring and the second upper protection ring are both provided with a first shaft sleeve matching the first rotating seat and a second shaft sleeve matching the second rotating seat.

[0011] As a further solution of the present invention: a first hydraulic guide wheel and a first fixed guide wheel are provided on the first connecting member.

[0012] As a further solution of the present invention: both ends of the second rotating seat are connected with elastic locking tongues via springs.

[0013] As a further solution of the present invention: a second fixed guide wheel is installed on the outer side surface of the second connecting member.

[0014] As a further solution of the present invention: the automatic fastening mechanism includes an oil cylinder, which is fixed on the inner side of the first protective ring. The inner side of the oil cylinder is connected to a connecting rod, and one end of the connecting rod away from the oil cylinder is fixedly connected to a synchronous moving block.

[0015] Beneficial effects of the present invention: In the present invention, the automatic fastening mechanism fixes the position of the first protective ring by cooperating with the first protective ring and the second protective ring. Specifically, when the first protective ring and the second protective ring are closed, the first protective ring and the second protective ring will form a cylinder. The first protective ring and the second protective ring can be nested on the outside of the optical cable or the optical cable connector before the first protective ring and the second protective ring are closed, and then the first protective ring and the second protective ring are closed. When the cylinder formed by the first protective ring and the second protective ring is moved to the set position in the channel, the automatic fastening mechanism can be started, and the first protective ring is locked by the automatic fastening mechanism, so that the overall position of the first protective ring and the second protective ring is fixed, that is, the position of the optical cable in the channel is locked, ensuring the stability of the optical cable in the channel, and improving the protection effect of the optical cable.

[0016] In the present invention, since the first connecting member extends beyond the outer side surfaces of the first lower arc ring and the first upper arc ring, when the first lower arc ring and the first upper arc ring are placed in the channel, the outer side surface of the first connecting member contacts the inner wall of the channel, and the first hydraulic guide wheel and the first fixed guide wheel provided on the first connecting member can greatly reduce the friction between the first connecting member and the inner wall of the channel, so that the movement of the first lower arc ring and the first upper arc ring in the channel can achieve low friction resistance, which facilitates the movement of the first lower arc ring and the first upper arc ring in the channel. The number of the first hydraulic guide wheels and the first fixed guide wheels are both two, and the first hydraulic guide wheels and the first fixed guide wheels are symmetrically arranged at both ends of the outer side surface of the first connecting member to facilitate supporting the first connecting member.

[0017] In the present invention, since the second connecting member extends beyond the outer side surfaces of the second lower protective ring and the second upper protective ring, when the second lower protective ring and the second upper protective ring are placed in the channel, the outer side surfaces of the second connecting member will contact the inner wall of the channel, and the second fixed guide wheels provided on the second connecting member can greatly reduce the friction force of the second connecting member when it moves on the inner wall of the channel, so that the second lower protective ring and the second upper protective ring can achieve low friction resistance when moving in the channel, which facilitates the movement of the second lower protective ring and the second upper protective ring on the inner wall of the channel. The number of the second fixed guide wheels is four groups, which are provided at both ends of the outer side surface of the second connecting member to facilitate supporting the second connecting member.

[0018] In the present invention, after the synchronous moving block is subjected to a driving force, the synchronous moving block will squeeze the piston inside the oil cylinder through the connecting rod, and the mutual engagement of the inverted teeth and the inverted tooth grooves will prevent the synchronous moving block from retreating, and the piston will squeeze the hydraulic oil inside the oil cylinder. When the hydraulic oil inside the oil cylinder is subjected to the squeezing force, the pressure will increase. Since the end of the oil cylinder away from the connecting rod is connected to the telescopic groove through the hydraulic oil channel, the hydraulic oil inside the oil cylinder will enter the interior of the telescopic groove through the hydraulic oil channel and squeeze the first hydraulic guide wheel. The first hydraulic guide wheel is slidably installed inside the telescopic groove. When the pressure of the hydraulic oil inside the telescopic groove increases, the telescopic groove will squeeze the first hydraulic guide wheel through the internal hydraulic oil, causing the first hydraulic guide wheel to move outward, that is, causing the first hydraulic guide wheel to act on the inner wall of the channel, so that the first protective ring and the second protective ring are fixed on the inner wall of the channel, that is, fixing the position of the first protective ring and the second protective ring. In this way, the first protective ring and the second protective ring can fix the position of the optical cable or the optical cable connector, reduce the axial tension of the optical cable or the optical cable connector, and protect the optical cable or the optical cable connector.

On the one hand, the first lower arc ring 11 and the first upper arc ring 12 can be fixedly connected together by the two first connecting members 13 to ensure the stability of the connection between the first lower arc ring 11 and the first upper arc ring 12. On the other hand, the symmetrical arrangement of the two first connecting members 13 can ensure the overall strength of the first lower arc ring 11 and the first upper arc ring 12. The inner arc surfaces of the first lower arc ring 11 and the first upper arc ring 12 are both provided with a plurality of The protrusions, several protrusions can form rough surfaces on the inner arc surfaces of the first lower arc ring 11 and the first upper arc ring 12, thereby increasing the direct friction between the inner arc surfaces of the first lower arc ring 11 and the first upper arc ring 12 and the side of the coated optical cable, ensuring that the first lower arc ring 11 and the first upper arc ring 12 are fixed on the side position of the optical cable, preventing the first lower arc ring 11 and the first upper arc ring 12 from sliding friction on the side of the optical cable, causing the first lower arc ring 11 and the first upper arc ring 12 to shift in the position of protecting the optical cable, affecting the protection effect of the first lower arc ring 11 and the first upper arc ring 12 on the optical cable.

The raised fixed block is integrally formed with the first lower arc ring 11 and the first upper arc ring 12, and the long axis runs through the side of the raised fixed block, so that there are protruding parts of the long axis on both sides of the raised fixed block, which is convenient for rotational connection with the second protective ring 2.

[0028] As an embodiment of the present invention, Figure 1-Figure 5 As shown, the second protective ring 2 includes a second lower protective ring 21 and a second upper protective ring 22, and at least a second connecting member 23 is fixedly connected between the second lower protective ring 21 and the second upper protective ring 22. The size of the second lower protective ring 21 and the second upper protective ring 22 matches and fits with the first lower arc ring 11 and the first upper arc ring 12, and the inner arc surface of the second lower protective ring 21 and the second upper protective ring 22 is also provided with a plurality of protrusions, so that the inner arc surface of the second lower protective ring 21 and the second upper protective ring 22 forms a rough surface, thereby increasing the friction between the inner arc surface of the second lower protective ring 21 and the second upper protective ring 22 and the optical cable or the optical cable connector, as shown in FIG. Figure 5As shown, two second connecting members 23 are provided between the second lower protective ring 21 and the second upper protective ring 22, and the two second connecting members 23 are symmetrically arranged between the second lower protective ring 21 and the second upper protective ring 22. On the one hand, the two second connecting members 23 can ensure the firmness between the second lower protective ring 21 and the second upper protective ring 22. On the other hand, the two second connecting members 23 provided for this purpose can ensure the stability of the overall strength between the second lower protective ring 21 and the second upper protective ring 22, so that the complete cylinder formed by the first lower arc ring 11 and the first upper arc ring 12 and the second lower protective ring 21 and the second upper protective ring 22 has higher strength and stability, which can improve the protection effect and stability of the optical cable or optical cable connector inside it. As for the righting effect, it should be noted that two first connecting parts 13 are provided between the first lower arc ring 11 and the first upper arc ring 12, and two second connecting parts 23 are provided between the second lower protective ring 21 and the second upper protective ring 22.

It should be noted that the first shaft sleeve 25 is matched with the first rotating seat 14, so the interior of the first shaft sleeve 25 is provided with a shaft groove that matches the raised fixing block and the long axis on the first rotating seat 14. Through the mutual cooperation of the long axis and the shaft groove, the first shaft sleeve 25 and the first rotating seat 14 can be rotated and stably connected together. The second lower protective ring 21 and the second upper protective ring 22 can also rotate freely on the first lower arc ring 11 and the first upper arc ring 12 through the cooperation of the first shaft sleeve 25 and the first rotating seat 14. The two ends of the second rotating seat 15 are connected with elastic lock tongues 15 through springs. 1. A lock tongue groove that fits with the elastic lock tongue 151 is provided inside the second sleeve 26 near the elastic lock tongue 151. When the second lower protective ring 21 and the second upper protective ring 22 are closed with the first lower arc ring 11 and the first upper arc ring 12 to form a complete cylinder, the elastic lock tongues 151 at both ends of the second rotating seat 15 can be embedded in the lock tongue grooves provided inside the second sleeve 26, thereby achieving a stable connection between the second sleeve 26 and the second rotating seat 15, that is, achieving a stable connection between the first lower arc ring 11 and the first upper arc ring 12 and the second lower protective ring 21 and the second upper protective ring 22, ensuring that the second lower protective ring 21 and the second upper protective ring 22 can be closed with the first lower arc ring 11 and the first upper arc ring 12 to form a stable and complete cylinder.

[0030] As an embodiment of the present invention, Figure 1-Figure 5 As shown, the first connecting member 13 is provided with a first hydraulic guide wheel 131 and a first fixed guide wheel 132. It should be noted that since the first connecting member 13 exceeds the outer side surfaces of the first lower arc ring 11 and the first upper arc ring 12, when the first lower arc ring 11 and the first upper arc ring 12 are placed in the channel, the outer side surface of the first connecting member 13 contacts the inner wall of the channel, and the first hydraulic guide wheel 131 and the first fixed guide wheel 132 provided on the first connecting member 13 can greatly reduce the friction between the first connecting member 13 and the inner wall of the channel, so that the movement of the first lower arc ring 11 and the first upper arc ring 12 in the channel can achieve low friction resistance, which facilitates the movement of the first lower arc ring 11 and the first upper arc ring 12 in the channel. The number of the first hydraulic guide wheel 131 and the first fixed guide wheel 132 are both two, and the first hydraulic guide wheel 131 and the first fixed guide wheel 132 are symmetrically arranged at both ends of the outer side surface of the first connecting member 13 to facilitate supporting the first connecting member 13.

[0031] As an embodiment of the present invention, Figure 1-Figure 5As shown, a second fixed guide wheel 24 is installed on the outer side of the second connecting member 23. It should be noted that since the second connecting member 23 exceeds the outer side of the second lower protective ring 21 and the second upper protective ring 22, when the second lower protective ring 21 and the second upper protective ring 22 are placed in the channel, the outer side of the second connecting member 23 will contact the inner wall of the channel. The second fixed guide wheel 24 set on the second connecting member 23 can greatly reduce the friction force of the second connecting member 23 when moving on the inner wall of the channel, so that the second lower protective ring 21 and the second upper protective ring 22 can move in the channel with low friction resistance, which facilitates the movement of the second lower protective ring 21 and the second upper protective ring 22 on the inner wall of the channel. The number of the second fixed guide wheels 24 is four, which are set at both ends of the outer side of the second connecting member 23 to facilitate supporting the second connecting member 23.

[0032] As an embodiment of the present invention, Figure 1-Figure 5 As shown, the automatic fastening mechanism 3 includes a cylinder 31, which is fixed on the inner side of the first protective ring 1. A connecting rod 33 is connected to the inner side of the cylinder 31, and a synchronous moving block 32 is fixedly connected to the end of the connecting rod 33 away from the cylinder 31. It should be noted that the specifications and volume of the cylinder 31 can be adaptively adjusted by those skilled in the art according to the size of the mounting slot 16. Figure 6 As shown, the end of the oil cylinder 31 away from the connecting rod 33 is connected to the telescopic groove 34 through the hydraulic oil channel. The inner end of the connecting rod 33 close to the oil cylinder 31 is fixedly connected to a piston that fits the oil cylinder 31. The inner side of the synchronous moving block 32 is provided with inverted teeth, and an inverted tooth groove is provided at the bottom surface of the mounting groove 16 near the inverted teeth. After the first protective ring 1 and the second protective ring 2 transport the optical cable or optical connector to the designated position of the channel, the synchronous moving block 32 can be pushed by a long rod or other tool. When the synchronous moving block 32 is pushed After the force is applied, the synchronous moving block 32 will squeeze the piston inside the oil cylinder 31 through the connecting rod 33, and the mutual engagement of the inverted teeth and the inverted tooth grooves will prevent the synchronous moving block 32 from retreating, and the piston will squeeze the hydraulic oil inside the oil cylinder 31. When the hydraulic oil inside the oil cylinder 31 is subjected to the squeezing force, the pressure will increase. Since the end of the oil cylinder 31 away from the connecting rod 33 is connected to the telescopic groove 34 through the hydraulic oil channel, the hydraulic oil inside the oil cylinder 31 will enter the interior of the telescopic groove 34 through the hydraulic oil channel and squeeze the first hydraulic guide wheel 131. Figure 6As shown, the first hydraulic guide wheel 131 is slidably installed inside the telescopic groove 34. When the pressure of the hydraulic oil inside the telescopic groove 34 increases, the telescopic groove 34 will squeeze the first hydraulic guide wheel 131 through the internal hydraulic oil, so that the first hydraulic guide wheel 131 moves outward, that is, the first hydraulic guide wheel 131 acts on the inner wall of the channel, so that the first protective ring 1 and the second protective ring 2 are fixed on the inner wall of the channel, that is, the position of the first protective ring 1 and the second protective ring 2 is fixed, so that the first protective ring 1 and the second protective ring 2 can fix the position of the optical cable or the optical cable connector, reduce the axial tension of the optical cable or the optical cable connector, and protect the optical cable or the optical cable connector.
