Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a pay-off rack for installing network cables. Background Art

[0002] As an essential tool in network communications construction, the cable rack's primary function is to support and orderly guide the laying and installation of network cables (such as Ethernet cables). By providing a stable support platform and a well-designed guiding structure, the cable rack ensures smooth routing during installation, thereby improving construction efficiency and quality. In complex network cabling projects, the cable rack plays a crucial role in connecting the cable's starting and ending points, making it a key piece of equipment for efficient and precise cabling.

[0003] Currently, there are a variety of foldable payouts on the market that feature a fixed ring for routing network cables. These payouts are ingeniously designed, making them not only easy to carry and store but also quick to deploy upon unfolding. Their key feature is that their foldable structure maximizes space utilization. Furthermore, the rings affixed to the payout serve as guides, guiding the cables through the payout. This design addresses the issues of traditional payouts, such as their large footprint and inconvenience in maneuverability, while ensuring smooth cable routing.

[0004] However, in practice, installing or replacing a cable reel often requires operators to completely remove the support rod in the center of the payout rack, a tedious and time-consuming process. Furthermore, the fixed ring, acting as a guide, is typically fixed in position and angle, meaning the cables at both ends of the reel must bend through a relatively small angle as they pass through the ring. This design can easily cause wear and tear on the cables, or even breakage, over prolonged or frequent use, impacting the quality and stability of the network signal. More seriously, for cables with thicker diameters or harder materials, this fixed ring guidance method can exacerbate damage and shorten their service life. Utility Model Content

[0005] In order to overcome the shortcoming that the network cable guide is easily worn, the utility model provides a pay-off rack for installing the network cable and protecting the network cable.

[0006] The locking mechanism is configured to lock the locking cam of the locking cam and the locking cam of the locking cam, wherein the locking cam is secured to the locking cam of the locking cam and the locking cam of the locking cam.

[0007] As an improvement to the above-mentioned scheme, the wire assembly includes a connecting rod, a limit plate, a wire frame, an extrusion block and a buffer roller. A sliding groove is opened on the first rocker arm, and the connecting rod is slidably connected to the sliding groove of the first rocker arm. One end of the connecting rod is connected to the limit plate, and the other end is connected to the wire frame for passing the network cable. Extrusion blocks are connected to the upper and lower sides of the wire frame, and a buffer roller is rotatably connected to the extrusion block.

[0008] As an improvement of the above solution, a reset spring is further included. The extrusion block is slidably connected to the wire frame, and the reset spring is connected between the extrusion block and the wire frame.

[0009] As an improvement to the above solution, it further includes auxiliary rollers, which are rotatably connected to the left and right sides of the wire frame.

[0010] As an improvement to the above solution, an anti-skid pad is further included, and the bottoms of the second swing arm and the third swing arm are connected with the anti-skid pad.

[0011] As an improvement to the above solution, a pull rope is further included, one end of the pull rope is connected to the limiting member, and the other end is connected to the end of the support rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The connecting rod slides within the sliding groove, and the rolling friction mechanism between the buffer roller and auxiliary roller within the wire frame ensures smooth guidance and effective protection of the network cable. The interference fit between the stopper and the holes in the first, second, and third swing arms allows the payout frame to fold quickly and unfold securely, eliminating the tedious insertion and removal of support rods and significantly improving the payout frame's space utilization and portability.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0021] Embodiment: A pay-off rack for installing a network cable, such as Figure 1-Figure 5 As shown, it includes a support rod 1, a network cable reel 101, a blocking screw 102, a first swing rod 2, a second swing rod 3, a third swing rod 4, a limiting member 5 and a wire assembly. One end of the support rod 1 is firmly connected to the first swing rod 2 and is rotatably connected to the second swing rod 3 and the third swing rod 4. The swing rods can flexibly rotate around the support rod 1. Two fixing holes 8 are opened on the first swing rod 2, a first limiting hole 6 is opened on the second swing rod 3, and a second limiting hole 7 is opened on the third swing rod 4. The limiting member 5 is interference fit with all the holes to achieve a stable limiting effect. When all the swing rods are folded, When folded, the second rocker arm 3 contacts the first rocker arm 2, the third rocker arm 4 is sleeved in the second rocker arm 3, and the limiter 5 is inserted into all the holes to limit the rotation of the first rocker arm 2, the second rocker arm 3 and the third rocker arm 4. The other end of the support rod 1 is threadedly connected with a blocking screw 102. When all the rocker arms are unfolded, the limiter 5 is inserted into the first limiting hole 6 and the second limiting hole 7, and supports the first rocker arm 2 to limit the rotation of all rocker arms. The support rod 1 is rotatably connected to the network cable reel 101, and the first rocker arm 2 is slidably connected to the wire assembly for guiding the network cable.

[0022] When folding, refer to Figure 2 , the first swing arm 2 and the second swing arm 3 have a surface fitted together, the third swing arm 4 is sleeved in the second swing arm 3, the limiting piece 5 passes through the two fixing holes 8 and the first limiting hole 6 and the second limiting hole 7, and the first swing arm 2, the second swing arm 3 and the third swing arm 4 are fixed together. When the network cable rack needs to be used, the limiting piece 5 is pulled out, the first swing arm 2 and the third swing arm 4 are rotated, and after the second swing arm 3 and the third swing arm 4 are at a certain angle, the limiting piece 5 is inserted into the first limiting hole 6 and the second limiting hole 7. At the same time, the top of the limiting piece 5 contacts the end of the first swing arm 2, thereby limiting the downward rotation direction of the first swing arm 2, reference Figure 3 When the network cable passes through the wire assembly on the first swing arm 2, the weight of the first swing arm 2 and the tension of the network cable cause the first swing arm 2 to rotate toward the third swing arm 4. The limiter 5 limits its top from rotating downward, and the blocking screw 102 is connected to the support rod 1 through its thread. When tightened, it can resist the edge of the network cable reel 101, thereby preventing it from slipping off the support rod 1 during rotation.

[0023] like Figure 2 and Figure 5 As shown, the wire assembly includes a connecting rod 10, a limiting plate 11, a wire frame 12, an extrusion block 13 and a buffer roller 14. A sliding groove 9 is opened on the first rocker arm 2. The connecting rod 10 is slidably connected to the sliding groove 9 of the first rocker arm 2. One end of the connecting rod 10 is connected to the limiting plate 11, and the other end is connected to the wire frame 12 for passing the network cable. The upper and lower sides of the wire frame 12 are connected to the extrusion block 13, and the buffer roller 14 is rotatably connected to the extrusion block 13.

[0024] Since the network cable is evenly wound on the network cable reel 101, when the network cable is pulled out, the tension of the network cable will cause the wire frame 12 to move left and right following the position of the network cable wound on the network cable reel 101. The connecting rod 10 slides in the sliding groove 9, thereby reducing the friction between the network cable and the wire frame 12. Moreover, the network cable contacts the buffer roller 14 when being pulled out, changing the sliding friction into rolling friction, thereby ensuring the surface quality of the network cable and reducing damage to the network cable.

[0025] like Figure 5 As shown, it also includes a return spring 15. The extrusion block 13 is slidably connected to the wire frame 12. The return spring 15 is connected between the extrusion block 13 and the wire frame 12. When the network cable contacts the buffer roller 14 on the extrusion block 13, the pressure generated is buffered by the return spring 15.

[0026] like Figure 5As shown, it also includes auxiliary rollers 16. Auxiliary rollers 16 are rotatably connected on the left and right sides of the wire frame 12. When the auxiliary rollers 16 on both sides of the wire frame 12 and the connecting rod 10 move left and right, the network cable contacts the auxiliary rollers 16, which also changes the sliding friction into rolling friction, further ensuring the surface quality of the network cable.

[0027] like Figure 1 and Figure 3 As shown, it also includes an anti-slip pad 17. The bottom of the second pendulum arm 3 and the third pendulum arm 4 are connected with the anti-slip pad 17. The second pendulum arm 3 and the third pendulum arm 4 are placed on the ground. If the ground is a smooth surface such as tiles, the anti-slip pad 17 can increase the friction between the second pendulum arm 3 and the third pendulum arm 4 and the ground, thereby improving the stability during the wire pulling process.

[0028] like Figure 3 As shown, it also includes a pull rope 18, one end of the pull rope 18 is connected to the limiter 5, and the other end is connected to the end of the support rod 1. After the limiter 5 is taken out, the pull rope 18 can hang the limiter 5 on the support rod 1, so it will not be lost, and the unfolding and folding process can be smoother.

[0029] The pay-off frame is centered around a support rod 1, one end of which connects to the first swing arm 2, which in turn pivots to connect to the second and third swing arms 3 and 4. The three elements securely switch between folding and unfolding through an interference fit between the stopper 5 and their respective holes. When folded, the second swing arm 3 rests against the first swing arm 2, while the third swing arm 4 slots into the second swing arm 3, secured by the stopper 5 inserted through each hole. When unfolded, the stopper 5 inserts into the first and second stopper holes 6 and 7, supporting the first swing arm 2 and limiting its rotation. The network cable passes through the conductor assembly on the first swing arm 2. This assembly uses a connecting rod 10 within a sliding slot 9 to drive the conductor frame 12 to move with the network cable, reducing friction. The buffer roller 14 and auxiliary roller 16 within the conductor frame 12 convert sliding friction between the network cable and the assembly into rolling friction, protecting the network cable surface. Furthermore, the combination of the squeeze block 13 and return spring 15 provides a cushioning effect, further enhancing protection. An anti-slip pad 17 ensures the stability of the second and third swing arms 3 and 4 when used on smooth surfaces. In addition, the design of the pull rope 18 facilitates the access to the limiting member 5 .

[0030] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
