Modular quick-mount cable tray

Abstract

This invention discloses a modular quick-installation cable reel, relating to the field of cable reel technology. It includes a cylindrical body and end plates located on both sides of the cylindrical body, and two clamping claws. Several square slots are evenly distributed along the circumference of the cylindrical body on the end plates. The clamping claws are C-shaped and engage with the square slots, with their openings facing the other end plate. A base is rotatably mounted on the clamping claws, and a clamping rod is mounted on the base, penetrating the base and movably engaging with it. This modular quick-installation cable reel provides a pair of clamping rods, each of which can be installed at multiple positions circumferentially on the end plates via the clamping claws. Thus, after the cable is completely wound onto the cylindrical body, the operator can engage the clamping claws with the corresponding square slots according to the position of the cable end, and then clamp the cable end with the two clamping rods. Compared to the prior art using adhesive tape, this significantly reduces the possibility of cable loosening.

Description

Technical Field

[0001] This invention relates to the field of cable reel technology, specifically a modular quick-installation cable reel. Background Technology

[0002] Cable reels are specialized tools used to wind cables during transportation, storage, and laying. They typically consist of a reel body and a bushing, and are commonly known as cable reels. They are mainly made of wood, steel, and plastic, and their core function is to protect cables from damage during handling and to facilitate loading, unloading, transportation, and storage. Existing technologies include some research on cable reels. For example, Chinese utility model patent CN218478394U discloses a cable reel comprising two outer supports, each with a first adapter hole and a first fixing hole in its middle; a cable drum with adapter plates at both ends, each adapter plate having a second adapter hole and a second fixing hole; the cable drum being positioned between the two outer supports and coaxially with them; two adapter shafts, each located at one of the two outer supports and passing through the first and second adapter holes; and a fixing member, partially passing through and detachably connected to the first fixing hole, with an elastic telescopic head at one end extending into the first fixing hole.

[0003] Existing cable reels, including those mentioned in the patent, lack dedicated components for securing cable ends. This leads to cables easily loosening after being wound on the reel, and loosened cables are prone to friction during transport or storage due to external vibrations. Currently, the main solution is to use tape to attach the cable ends to the reel's end plate, but this method is generally not very effective at securing the cables. Summary of the Invention

[0004] The purpose of this invention is to provide a modular quick-installation cable reel to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular quick-installation cable reel, comprising a cylindrical body and end plates located on both sides of the cylindrical body, and further comprising two claws; the end plates are evenly provided with a plurality of square grooves along the circumference of the cylindrical body; the claws are C-shaped and engage with the square grooves, with the openings of the claws facing the other end plate; a base is rotatably mounted on the claws, and a clamping rod is mounted on the base, the clamping rod penetrating the base and engaging movably with the base.

[0006] As a preferred embodiment of the present invention, the clamping rod includes a round rod portion that movably engages with the base, with an annular portion installed at one end and a plate-shaped portion installed at the other end.

[0007] As a preferred embodiment of the present invention, one of the round rod portions has a threaded rod fixedly installed at its end, and the other round rod portion has a threaded groove that mates with the threaded rod at its end.

[0008] As a preferred embodiment of the present invention, rubber sheets are fixedly installed on the opposing surfaces of the two plate-shaped parts, and anti-slip grooves are provided on the rubber sheets.

[0009] As a preferred embodiment of the present invention, the cylinder body is rotatably coupled with the end plate, and an end cap is installed at the end of the cylinder body by means of a threaded connection. The end cap and the end plate cooperate to limit the axial movement of the cylinder body.

[0010] As a preferred embodiment of the present invention, a plurality of rollers that fit against the cylinder are uniformly installed on the end plate.

[0011] As a preferred embodiment of the present invention, a sliding rod is slidably mounted on the claw, and an arc-shaped plate is fixedly mounted on one end of the sliding rod. The inner arc surface of the arc-shaped plate is in contact with the outer circumferential surface of the end cover. The arc-shaped plate has a first state of being in contact with the outer circumferential surface of the end cover and a second state of being separated from the outer circumferential surface of the end cover.

[0012] As a preferred embodiment of the present invention, the end cap has a plurality of protrusions evenly distributed along the circumferential direction, parallel to its axial direction.

[0013] As a preferred embodiment of the present invention, a rotating shaft is fixedly installed on the base, and a torsion spring is connected between the rotating shaft and the pawl.

[0014] As a preferred embodiment of the present invention, the other end of the slide rod forms a wedge-shaped bend, and a limiting plate that cooperates with the inclined surface of the wedge-shaped bend is slidably installed on the pawl; a rotating plate corresponding to the position of the limiting plate is fixedly installed on the rotating shaft.

[0015] In the above technical solution, the present invention provides a modular quick-install cable reel equipped with a pair of clamping rods, each of which can be installed at multiple positions around the end plate via claws. Thus, after the cable is completely wound onto the reel, the operator can engage the claws with the corresponding square grooves according to the position of the cable end, and then clamp the cable end with the two clamping rods. Compared to the prior art's method of attaching with tape, this significantly reduces the possibility of cable loosening. Furthermore, during cable release, the ends of the two clamping rods contact the ground, providing support to the end plate and preventing it from rolling over due to the rotation of the reel, thereby ensuring the overall stability of the cable reel during cable release.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment provides a modular quick-installation cable reel, including a cylindrical body 1 and end plates 2 located on both sides of the cylindrical body 1. The cylindrical body 1 and the end plates 2 are rotatably fitted. An end cap 7 is installed at the end of the cylindrical body 1 via a threaded connection. The end cap 7 cooperates with the end plates 2 to axially limit the movement of the cylindrical body 1. Several rollers are evenly installed on the end plates 2 to fit against the cylindrical body 1, thereby reducing the friction between the end plates 2 and the cylindrical body 1. A power interface is installed on the cylindrical body 1. One end of the cable is connected to the power interface, and the other end is connected to the electrical equipment. During storage and transportation, the cable is wound around the cylindrical body 1; during use, the operator pulls the cable out of the cylindrical body 1, and the cylindrical body 1 rotates continuously.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the modular quick-install cable reel in this embodiment also includes two C-shaped claws 3; several square grooves 201 are evenly opened along the circumference of the cylinder 1 on the end plate 2, and the claws 3 engage with the square grooves 201, with the openings of the claws 3 facing the other end plate 2. A base 4 is rotatably mounted on the claw 3, and a clamping rod 5 is mounted on the base 4. The clamping rod 5 includes a round rod portion 501 that movably engages with the base 4, penetrating the base 4 and movably engaging with it. An annular portion 502 is fixedly installed at one end of the round rod portion 501, and a plate-like portion 503 is fixedly installed at the other end. The function of the annular portion 502 is to prevent the clamping rod 5 from falling off the base 4. A threaded rod 6 coaxial with one of the round rod portions 501 is fixedly installed at the end of the other round rod portion 501, and a threaded groove that engages with the threaded rod 6 is opened at the end of the other round rod portion 501.

[0030] Specifically, when storing and transporting cables, the operator first winds the cable around the cylinder 1, locates the cable end, and then engages the first clamp 3 (without the threaded rod 6) with the corresponding square groove 201, ensuring that the inner end face of the clamp 3 is in contact with the end plate 2. Figure 1 As shown; then rotate the base 4 so that the round rod portion 501 is parallel to the axis of the cylinder 1. Next, attach the cable end to the corresponding plate portion 503 and temporarily fix it to the plate portion 503 with tape. The operator places the second claw 3 on the corresponding square slot 201 (the inner end face of the claw 3 is not attached to the end plate 2, that is, the round rod portions 501 of the two clamping rods 5 are not connected), and then rotate the base 4 so that the round rod portion 501 is also parallel to the axis of the cylinder 1. In this state, rotate the clamping rod 5 on the second claw 3 so that the threaded rod 6 and the threaded groove are engaged. As the clamping rod 5 rotates relative to the second claw 3, it also drives the second claw 3 to move closer to the first claw 3. The two plate portions 503 also move closer until the two plate portions 503 clamp the cable. After the plate-shaped part 503 clamps the cable, the two clamping rods 5 are connected together by a threaded engagement, so the base 4 cannot rotate relative to the claw 3, and the cable end is firmly clamped in a stationary state relative to the cylinder 1.

[0031] like Figure 2 As shown, rubber sheets 504 are fixedly installed on the opposing surfaces of the two plate-shaped parts 503. Anti-slip grooves are provided on the rubber sheets 504 to increase the friction between them and the cable and ensure the clamping effect.

[0032] When cables are needed, operators fix the cable reel according to the actual working environment. If there are hooks or other hanging objects, the end plate 2 can be directly hung on the hooks, which pass through the square groove 201 to suspend the entire cable reel. In this state, the operator only needs to pull the cable, and the cable will be continuously released from the cylinder 1, and the cylinder 1 will continuously rotate relative to the end plate 2. However, in some working situations, there are no hooks available, and the operator can only place the cable reel directly on the ground. However, the ground cannot limit the end plate 2. When the operator pulls the cable, the rotation of the cylinder 1 may cause the end plate 2 to roll. Even if the end plate 2 is made into a polygonal shape with sharp edges, it is not possible to completely prevent the end plate 2 from rolling. To address this problem, this embodiment solves it by the following method: After the operator places the cable reel on the ground, he rotates the clamping rods 5, causing the two clamping rods 5 to disengage from the threaded connection, and the cable is simultaneously released from the clamping state. Then, the base 4 is rotated 90°, so that the clamping rods 5 are rotated to a state perpendicular to the axis of the cylinder 1, such as... Figure 3 As shown. Thus, while the edge of end plate 2 contacts the ground, the end of clamping rod 5 also contacts the ground, providing overall support for the cable reel. For end plate 2 to roll, clamping rod 5 must roll. Obviously, the rolling force applied to end plate 2 by cylinder 1 is insufficient for end plate 2 to overcome the support between clamping rod 5 and the ground and roll. Even if end plate 2 rolls at a certain angle, causing relative movement between clamping rod 5 and base 4, square groove 201 will block the plate-shaped part 503, preventing clamping rod 5 from excessively retracting.

[0033] In summary, the clamping rod 5 in this embodiment not only clamps the cable end during cable storage and transportation, but also prevents the end plate 2 from rolling by supporting the ground during cable release.

[0034] Example 2

[0035] like Figure 4 and Figure 5 As shown, based on the previous embodiment, in this embodiment, a sliding rod 8 is slidably mounted on the claw 3, and an arc-shaped plate 9 is fixedly mounted on one end of the sliding rod 8. The inner arc surface of the arc-shaped plate 9 mates with the outer circumferential surface of the end cover 7. The arc-shaped plate 9 has a first state of being in contact with the outer circumferential surface of the end cover 7, and a second state of being separated from the outer circumferential surface of the end cover 7. During cable transportation and storage, an external force acts on the sliding rod 8, causing a large static friction force between the arc-shaped plate 9 and the end cover 7, preventing the end cover 7 and the cylinder 1 from rotating relative to the end plate 2, and reducing the risk of the cable head falling off between the two clamping rods 5 due to the rotation of the cylinder 1. When no external force acts on the sliding rod 8, no friction force is generated between the arc-shaped plate 9 and the end cover 7. Several rubber protrusions parallel to their axial direction are evenly distributed along the circumferential direction on the circumferential surface of the end cover 7 to increase the friction force between the end cover 7 and the arc-shaped plate 9 when they are tightly fitted together.

[0036] A rotating shaft 10 is fixedly mounted on the base 4, and a torsion spring 11 connects the rotating shaft 10 and the chuck 3. When no external force is applied, the torsion spring 11 keeps the rotating shaft 10 and the base 4 in a fixed position. Figure 4 The state shown indicates that the axis of clamping rod 5 remains perpendicular to the axis of cylinder 1, thus ensuring the supporting force between clamping rod 5 and the ground. In this state, end cap 7 is separated from arc plate 9, and end cap 7 and cylinder 1 can rotate freely relative to end plate 2.

[0037] like Figure 6 and Figure 7 As shown, the other end of the slide rod 8 forms a wedge-shaped bend. A limiting plate 12, which slidably engages with the inclined surface of the wedge-shaped bend, is slidably mounted on the claw 3. The end face of the limiting plate 12 is inclined, meaning that the limiting plate 12 is in contact with the inclined surface on the slide rod 8. When the limiting plate 12 slides relative to the claw 3, it will push the slide rod 8 to slide synchronously. A rotating plate 13, corresponding to the position of the limiting plate 12, is fixedly mounted on the rotating shaft 10. During the transportation and storage of the cable, the torsion spring 11 is in a torsional state. That is, when the operator rotates the base 4 to make the clamping rod 5 parallel to the axis of the cylinder 1, a force will be applied to the torsion spring 11 to deform it. Figure 6 In this state, the base 4 and clamping rod 5 reverse and reset to their original positions. Figure 4 The trend of the state is that, however, since the two clamping rods 5 are connected by threads, neither the base 4 nor the clamping rods 5 can be reversed and reset. Figure 6 In this state, the rotating plate 13 is relative to Figure 4 It rotated 90°, and it was in Figure 6 The state is tightly fitted with one end of the limiting plate 12, and the limiting plate 12 acts as a retaining force against the slide rod 8, thereby pressing the arc-shaped plate 9 against the circumferential surface of the end cover 7. In summary, in this embodiment, rotating the base 4 can not only adjust the angle of the clamping rod 5, but also switch the state of the arc-shaped plate 9.

[0038] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
