Description

Technical Field

[0001] The invention belongs to the field of cable installation, in particular to a communication cable installation device. Background Art

[0002] Compared with power supply cables, communication cables are thicker and require more solid support during the installation process. Brackets are often installed on adjacent walls with expansion screws, and then the communication cables are fixed on the brackets. They are usually fixed with clips suitable for the cables. The size of the clips needs to be replaced according to the thickness of the cable, which is inconvenient to use. At the same time, the installation of the clips is cumbersome and requires bolts to fix the clips. The diameter of the clips cannot be changed. When the cable expands due to heat, the clips can easily break the cables. Although the current of communication cables is usually small, when used for a long time or multiple cables are densely laid, heat accumulation will also cause the temperature to rise significantly, causing the cable to expand. If the communication cable is in a high temperature environment, such as close to a heat source or outdoors at high temperature, the cable will absorb ambient heat and the temperature will rise, causing expansion.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] A communication cable installation device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it includes a base 1, on which two transverse tubes 3 are fixedly installed through columns 2, the two transverse tubes 3 are symmetrically distributed on the left and right, and the two transverse tubes 3 are arranged in parallel, and the characteristics are: a moving rod 4 is arranged below the two transverse tubes 3, and a moving plate 5 is movably arranged below the moving rod 4, and reserved holes are respectively provided on the moving plate 5 corresponding to the columns 2, and the columns 2 are slidably located in the corresponding reserved holes, which can increase the stability of the moving plate 5 moving up and down, and an adjusting device capable of adjusting the height of the moving plate 5 is provided on the base 1, and a plurality of piston cylinders 6 are fixedly provided on the moving plate 5, and piston plates 7 are respectively airtightly fitted in the piston cylinders 6, and the piston plates 7 are fixedly connected to the moving rods 4 through piston rods 8 respectively, and the piston plates 7 and the piston cylinders 6 are respectively fixedly connected. The two ends of the cross tube 3 are connected by a return spring 9, which is sleeved on the outer periphery of the corresponding piston rod 8. One end of the return spring 9 is fixedly connected to the corresponding piston plate 7, and the other end is fixedly connected to the corresponding piston cylinder 6. Both ends of the cross tube 3 are closed to form a cavity, and the inside of the cavity is connected to the inside of the piston cylinder 6 by a connecting pipe 10. The side of the cross tube 3 on one side is fixedly connected to the two ends of the fastening rope 11, and the two ends of the fastening rope 11 are distributed front and back. One end of the fastening rope 11 is fixedly connected to the front part of the cross tube 3, and the other end is fixedly connected to the rear part of the cross tube 3. The side of the cross tube 3 on the other side is fixedly provided with a blocking rod 12, which is located in the middle part of the cross tube 3, and the middle part of the fastening rope 11 can hook the blocking rod 12. The present invention has a simple structure and an ingenious design. It can fix the cable by a spirally wound fastening rope, which can adapt to cables of various diameters and is convenient to use. It can also use the heat generated by the thermal expansion of the cable to automatically adjust the strength of the fastening rope to fix the cable, reduce the breakage of the cable, meet actual needs, and is suitable for promotion.When using the present invention, first fix the base 1 in an appropriate position, then place the communication cable to be fixed on the two transverse tubes 3, and make the communication cable parallel to the transverse tube 3, then spirally wind the fastening rope 11 around the communication cable, the transverse tube 3 and the outer periphery of the moving rod 4, the front and rear parts of the fastening rope 11 have opposite spiral directions, when the communication cable moves back and forth, the fastening rope 11 on one side can be tightened, and the winding is tighter, reducing the movement of the communication cable, until the middle part of the fastening rope 11 just hooks the blocking rod 12, and the winding of the fastening rope 11 is completed, at this time, an adjustment device is provided to adjust the movement of the moving plate 5, so that the moving plate 5 moves downward, and the moving plate 5 drives the piston cylinder 6, the piston plate 7, and the piston rod 8 to move downward by means of the moving rod 4, at this time, the reset spring 9 may not be compressed, and the moving rod 4 forms a downward pulling force on the lower part of the spiral fastening rope, so that the spiral fastening rope is further tightened, and the communication cable is tightly fitted with the two transverse tubes 3 and the upper part of the spiral fastening rope, completing the communication Cable fixation; when the communication cable expands due to heat, the heat of the communication cable is transferred to the cross tube 3, causing the air in the cross tube 3 to expand due to heat, and is transferred to the inside of the piston cylinder 6 through the connecting tube 10, causing the gas between the piston cylinder 6 and the piston plate 7 to expand due to heat, thereby pushing the piston plate 7 to move upward relative to the piston cylinder 6, and the piston plate 7 drives the piston rod 8 and the moving rod 4 to move upward, the reset spring 9 is compressed, and the tension of the moving rod 4 on the fastening rope 11 is reduced, so that the diameter of the spiral fastening rope formed by the fastening rope 11 increases to adapt to the increased diameter of the communication cable due to heat expansion, and the fixing and fastening force of the fastening rope 11 on the communication cable does not change much, avoiding hard contact between the communication cable and the fastening rope 11 when the communication cable expands due to heat, reducing damage to the communication cable, and at the same time preventing the communication cable from falling off from the fastening rope 11; when the temperature of the communication cable drops again, the above process is reversed, the reset spring 9 causes the piston plate 7 to move downward and reset, and the fastening rope 11 keeps the communication cable fastened and fixed.

[0017] Specifically, if Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjusting device described in this embodiment includes a support rod 20, which is fixedly mounted on the base 1, a sliding rod 21 is fixedly mounted on the support rod 20, a sleeve 22 is slidably mounted on the sliding rod 21, and the sleeve 22 can only slide left and right along the sliding rod 21. The sliding rod 21 is a square rod, and the sleeve 22 is connected to the support rod 20 through a spring 23. The spring 23 is sleeved on the outer periphery of the sliding rod 21, one end of the spring 23 is fixedly connected to the sleeve 22, and the other end is fixedly connected to the support rod 20. The outer periphery of the sleeve 22 is rotatably mounted with a coaxial gear ring 24 through a one-way bearing, and a bar rack 25 is meshingly provided on one side of the gear ring 24, and the bar rack 25 is fixed on the movable plate 5. When the movable plate 5 is manually adjusted to move and the movable plate 5 moves downward relative to the base 1, the movable plate 5 drives the bar rack 25 to move downward, and the bar rack 25 drives the gear ring 24 to rotate forwardly. At this time, the one-way bearing will not prevent the gear ring 24 from rotating, and the gear ring 24 rotates relative to the sleeve 22, and the sleeve 22 and the slide bar 21 do not rotate. The movable plate 5 is released, and due to the action of the one-way bearing, the movable plate 5 and the bar rack 25 cannot move upward and reset. At this time, the gear ring 24 cannot rotate in the opposite direction relative to the sleeve 22, and the movable plate 5 can only move downward. When the movable plate 5 needs to be moved upward and reset, the sleeve 22 is pushed to the right, the spring 23 is compressed, and the gear ring 24 is separated from the bar rack 25. At this time, the movable plate 5 can move upward and reset.

[0018] Specifically, Figure 2 As shown, the middle part of the fastening rope 11 of this embodiment is fixedly installed with a collar 30, and the collar 30 can be mounted on the outer periphery of the blocking rod 12. The collar 30 divides the fastening rope 11 into two parts, front and back. When the collar 30 is mounted on the outer periphery of the blocking rod 12, the spiral fastening rope spirally wound around the outer periphery of the cable is divided into two parts, front and back. When the cable moves forward and backward relative to the cross tube 3, the friction between the cable and the fastening rope 11 is used to drive the spiral fastening rope to move forward or backward, so that the spiral fastening rope is tightened to increase the communication fixing force; the collar 30 divides the fastening rope 11 into two parts, front and back, so the fastening ropes 11 of the front and back parts are tightened; and the fastening rope 11 on one side is damaged, which does not affect the function of the fastening rope 11 on the other side of the collar 30.

[0019] Further, such as Figure 1 and Figure 2 As shown, in this embodiment, a row of several cross bars 40 are fixedly installed on the opposite sides of the two cross tubes 3. When the fastening rope 11 is fixedly wound around the cable, the fastening rope 11 only passes between the two adjacent cross bars 40 in front and back once, that is, when the fastening rope 11 is spirally wound around the cable and the outer periphery of the cross tube 3, the cross bars 40 separate the fastening rope 11, increasing the uniformity of the spiral winding of the fastening rope 11, so that the winding force distribution of the fastening rope 11 on the cable is more uniform.

[0020] Furthermore, if Figure 1 and Figure 2As shown, the base 1 of this embodiment is provided with a plurality of mounting holes 50. Bolts are used to fix the base 1 in a proper position through the mounting holes 50.

[0021] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, the piston plate 7 of the present embodiment is fixedly mounted with a small piston cylinder 60, a through groove 61 connected to the small piston cylinder 60 is provided on the piston plate 7, the lower part of the piston cylinder 6 is connected to the lower part of the small piston cylinder 60 through the through groove 61, a piston 62 is airtightly slidably mounted in the small piston cylinder 60, the diameter of the through groove 61 is smaller than the diameter of the piston 62, so the piston 62 will not slide out of the small piston cylinder 60, a push rod 63 is fixedly mounted on the piston 62, and the push rod 63 is slidably mounted on the small piston cylinder 60, and the piston cylinder 6 A slide groove 64 is provided at the upper part, and a stopper 65 is slidably installed in the slide groove 64. The stopper 65 can only slide left and right in the corresponding slide groove 64. The stopper 65 is connected to the piston cylinder 6 by a tension spring 66. The tension spring 66 is sleeved on the outer periphery of the stopper 65. One end of the tension spring 66 is connected to the stopper 65, and the other end is connected to the piston cylinder 6. The top side of the small piston cylinder 60 is in contact with the bottom side of the stopper 65. A guide slope 67 is provided on the side of the stopper 65, and the upper end of the push rod 63 is in contact with the guide slope 67. When the air pressure at the bottom of the piston cylinder 6 increases, the bottom side of the stopper 65 contacts and cooperates with the top side of the small piston cylinder 60, limiting the upward movement of the piston plate 7 relative to the piston cylinder 6. At this time, the air pressure in the small piston cylinder 60 increases, and the piston 62 moves upward relative to the small piston cylinder 60. The piston 62 drives the push rod 63 to move upward, and the upper end of the push rod 63 slides along the guide slope 67, giving the stopper 65 a lateral thrust. The stopper 65 gradually moves away from the top of the small piston cylinder 60, and the tension spring 66 is stretched and stored. At this time, the piston plate 7 can It is enough to drive the small piston cylinder 60 to move upward, and at the same time the piston rod 8 and the moving rod 4 move upward; when the air pressure in the piston cylinder 6 drops and recovers, the above process is performed in reverse order, the piston plate 7 moves downward and resets relative to the piston cylinder 6, and the stopper 65 is reset under the elastic tension of the tension spring 66, and the bottom side of the stopper 65 contacts and cooperates with the top side of the small piston cylinder 60 again, limiting the upward movement of the piston plate 7, thereby avoiding the situation where the piston plate 7 moves upward relative to the piston cylinder 6 due to excessive tightening tension of the tightening rope 11 on the cable.

[0022] Furthermore, if Figure 2 As shown, the movable plate 5 of this embodiment is provided with a threaded through hole 70, and the internal thread of the threaded through hole 70 is matched with a mounting bolt 71. After the movable plate 5 is adjusted to move downward to a proper position, the bolt 71 is screwed again so that the lower end of the bolt 71 abuts against and contacts the top side of the base 1 to prevent the movable plate 5 from moving further downward.

[0023] Finally, 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
