Description

Technical Field

[0001] The present invention relates to the technical field of wire fixing, and in particular to a wire retainer and a retaining method. Background Art

[0002] In the process of electrification of modern industry and daily life, the reasonable layout and management of wires have become particularly important. Wires not only carry the task of transmitting energy and signals, but the regularity and aesthetics of their layout also directly affect the safety and reliability of the electrical system. Especially in the application of flexible wires, such as drag chain cables, towing cables, mobile cables and robot cables, the dynamic management of wires is particularly critical.

[0003] At present, there are some shortcomings in the maintenance and management of wires in the existing technology: 1. When arranging multiple flexible wires, cable ties are generally used to tie the wires into a bundle to make the wire distribution more regular. However, due to their special material problems, flexible wires are prone to twisting and entanglement, resulting in a non-parallel layout between the multiple wires in a bundle. This layout will cause uneven distribution of the electromagnetic field between the wires, increase electromagnetic interference between the wires, and affect the stability and accuracy of signal transmission.

[0004] 2. Multiple flexible wires that are not arranged in parallel have large areas of contact, which hinders air circulation and reduces heat dissipation efficiency. Long-term overheating will cause aging or damage of the wires.

[0005] 3. After bundling multiple flexible wires, due to the easy-to-bend nature of the wires, the actual lengths of the wires differ significantly in the overall length. When the connected equipment is frequently moved, this length difference causes uneven longitudinal force between the wires, and some wires may shift longitudinally, thereby weakening the stable retention effect of the wires.

[0006] Therefore, it is necessary to provide a wire retainer and a retaining method to solve the above technical problems. Summary of the invention

[0017] In a preferred embodiment of the present invention, in S3, after the electric wire is fixed, an anti-roll mechanism is used to connect with a plurality of balls on the first ball rack or the second ball rack so that the balls no longer roll.

[0018] The present invention solves the defects existing in the background technology and has the following beneficial effects: (1) The present invention provides a wire retainer, which is provided with a frame, and a plurality of threading assemblies arranged in the frame. The plurality of threading assemblies are arranged circumferentially, and each threading assembly is a detachable structure, including: a first ball rack and a second ball rack. The central axes of the wire, the first ball rack and the second ball rack coincide with each other. If the plurality of wires in the wire retainer are straight, then the wires are parallel to each other. This layout helps to evenly distribute the electromagnetic field and reduce electromagnetic interference between the wires. In addition, the parallel arrangement of the wires helps air circulation, thereby improving the heat dissipation efficiency and avoiding aging or damage of the wires due to overheating.

[0019] (2) When the present invention is used in some flexible wires, such as in scenarios where they are used as drag chain cables, towing cables, mobile cables, robot cables, etc., one end of the wire / cable will be constantly moving.

The anti-roll mechanism cooperates with the anti-roll grooves, and the magnets are sunk into the anti-roll grooves and magnetically adsorbed with the balls, thereby achieving the fixation of the balls, and preventing the problem that after the wires are fixed, the radial force of the wires is applied, causing the balls to rotate, and then the radial position of the wires moves.

[0022] (5) The present invention provides a wire holding method, which is used in conjunction with a wire holder. After the wire passes through a first ball rack and a second ball rack, the first ball rack is used to initially position the wire, and then the first ball rack is controlled to move back and forth on a guide rail along the radial direction of the wire. After the wire is straightened, the second ball rack is used to perform final positioning to ensure that the tension of the wire is stable, that is, multiple wires are parallel to each other.

[0025] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention, unless otherwise specified, "multiple" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0029] The invention provides a wire retainer which is suitable for arranging and fixing flexible wires / cables and can also be used for assisting in the laying process of wires / cables.

[0030] like Figure 1 As shown, the present invention provides a wire retainer, including a frame 1, and a plurality of threading assemblies 2 arranged inside the frame 1, characterized in that: the plurality of threading assemblies 2 are arranged circumferentially, and the number of the threading assemblies 2 is set according to the actual number of wires 3 / cables, preferably 3-6, and multiple wires 3 / cables can be arranged or fixed at the same time.

[0031] like Figure 2 As shown, each threading assembly 2 is a detachable structure, including: a first ball rack 21, a second ball rack 22, and a driving mechanism 23 corresponding to the first ball rack 21 and the second ball rack 22; that is, the first ball rack 21 and the second ball rack 22 are independent, the distance between the first ball rack 21 and the second ball rack 22 is adjustable, and the central axis of the first ball rack 21 and the second ball rack 22 coincides.

[0032] Furthermore, the central axes of the wire 3, the first ball rack 21 and the second ball rack 22 also coincide with each other. If the wires 3 in the wire holder are straight, the wires 3 are parallel to each other. This layout helps to evenly distribute the electromagnetic field and reduce electromagnetic interference between the wires 3. The parallel arrangement of the wires 3 helps air circulation, thereby improving the heat dissipation efficiency and avoiding aging or damage of the wires 3 due to overheating.

[0033] In the use of some flexible wires, such as as drag chain cables, towing cables, mobile cables, robot cables, etc., one end of the wire 3 / cable will move continuously. The wire retainer of the present invention can bundle several wires 3 / cables into one strand, and space is left between each wire 3 / cable, which can reduce mutual friction and damage caused by vibration in a dynamic environment.

[0034] like Figure 3As shown, the first ball rack 21 and the second ball rack 22 both include: a ring body 24, a fixed ball group 25 and a movable ball group 26 arranged in the ring body 24; a driving mechanism 23 is used to control the movable ball group 26 to pop out and fix the wire 3; the first ball rack 21 and the second ball rack 22 are arranged along the length direction of the rack body 1, the first ball rack 21 is in front, and the second ball rack 22 is in the back, and the wire 3 first passes through the first ball rack 21 and then passes through the second ball rack 22.

[0035] It is worth noting that the ring body 24 is a coaxially arranged two metal ring structures, and a connecting rib is arranged between the metal ring structures. The diameters of the ring bodies 24 of the first ball rack 21 and the second ball rack 22 can be the same or different, and are arranged according to different usage scenarios, and the present invention does not make specific limitations. The fixed ball group 25 and the movable ball group 26 are both composed of a number of balls and corresponding ball sleeves. The size of the balls is the same, and both are made of steel balls. Among them, the ball sleeve of the fixed ball group 25 is fixedly connected to the surface of the ring body 24, and the number of balls in the fixed ball group 25 is more than half of the number of balls on the first ball rack 21 or the second ball rack 22. The movable ball group 26 moves in the ring body 24 along a fixed straight line direction, that is, in the direction toward the center of the circle, to achieve a change in the space inside the first ball rack 21 or the second ball rack 22, to ensure the contact or non-contact between the wire 3 and the balls in the first ball rack 21 or the second ball rack 22, and the change in the degree of extrusion of the balls on the surface of the wire 3.

[0036] Furthermore, the driving mechanism 23 is used to control the movement of the movable ball group 26 to achieve the tightness of the contact between the balls and the surface of the wire 3, thereby achieving the loosening and fixing operations of the wire 3.

[0037] like Figure 5 As shown, the movable ball group 26 also includes: a connecting plate 261, and a plurality of parallel limiting grooves 262 provided on the connecting plate 261, the length direction of the limiting grooves 262 being along the moving direction of the movable ball group 26, and the number is preferably two. A limiting rod 263 is provided on the ring body 24 corresponding to the limiting groove 262, the limiting rod 263 is inserted into the limiting groove 262, the limiting rod 263 is vertically arranged, and is a cylinder, and the outer surface of the limiting rod 263 is slidably connected to the inner wall of the limiting groove 262. It can ensure that the movable ball group 26 only moves in the set direction to avoid deviation. A limiting plate 264 is also provided on the ring body 24, and the limiting plate 264 is a two-section structure, which is slidably connected to the upper and lower surfaces of the connecting plate 261 respectively. This setting ensures that the movement of the connecting plate 261 will not appear in a situation where one end is high and the other end is low. The coordinated use of the above two structures ensures that under the action of the driving mechanism 23 , the movable ball group 26 pops out stably, quickly and accurately, thereby fixing the electric wire 3 .

[0038] like Figure 2As shown, the frame 1 includes: a support portion 11, a connection portion 12, and a telescopic mechanism 13 disposed between the support portion 11 and the connection portion 12; the connection portion 12 is respectively connected to the first ball rack 21 and the second ball rack 22, and the telescopic mechanism 13 is used to control the first ball rack 21 to move along the length direction of the frame 1. The support portion 11 is the outermost frame structure of the frame 1, which serves as the foundation of the entire wire 3 retainer to ensure the stable installation of each component. The telescopic mechanism 13 is installed in the support portion 11, and the connection portion 12 is installed on the telescopic mechanism 13, that is, the connection portion 12 can move on the telescopic mechanism 13, thereby driving the first ball rack 21 or the second ball rack 22 to move.

[0039] Furthermore, a triangular leg may be provided on one side of the support portion 11 to support the plane to prevent the wire 3 holder from rolling over, and a mounting hole may be provided on the leg to fix it on the plane by bolts.

[0040] like Figure 3 As shown, the driving mechanism 23 includes: a rotating disk 231 arranged at the center of the connecting portion 12, a plurality of connecting rods 232 arranged on the surface of the rotating disk 231, and a driving rod 233 arranged on the other side of the rotating disk 231. The plurality of connecting rods 232 are arranged circumferentially, and the other end of the connecting rod 232 is connected to the movable ball group 26. One end of the connecting rod 232 is rotatably connected to the surface of the rotating disk 231, and the other end is rotatably connected to the surface of the connecting plate 261. The plurality of connecting rods 232 are arranged circumferentially. The rotating disk 231 is rotatably arranged at the center of the connecting portion 12, that is, at the center position of the first ball rack 21 or the second ball rack 22 arranged in the plurality of circumferences. Each connecting rod 232 on the rotating disk 231 corresponds to a first ball rack 21 or a second ball rack 22. The rotation of the rotating disk 231 drives the connecting rod 232 to rotate, thereby driving the corresponding movable ball group 26 to move.

[0041] In one embodiment of the present invention, Figure 4 As shown, one end of the driving rod 233 is rotatably connected to the surface of the rotating disk 231, and the connection position is offset from the center of the circle; a snap ring is provided on the connecting portion 12, and the rod body of the driving rod 233 is inserted into the snap ring, and a fixing hole is provided on the surface, and bolts are provided on the surface of the snap ring corresponding to the fixing hole, and the bolts are connected to the fixing hole to fix the position of the driving rod 233 (not shown in the figure). This design can ensure that the displacement of the driving rod 233 is within a fixed range, thereby ensuring that the position range of the movable ball group 26 is fixed. It is worth noting that the rod body of the driving rod 233 passes through the gap between the two first ball racks 21 or the second ball racks 22, and can control the driving mechanism 23 without being hindered by the wire 3 after passing through the wire 3.

[0042] In another embodiment of the present invention, a worm wheel is provided on one side of the rotating disk 231, and the worm wheel is coaxially arranged with the rotating disk 231. One end of the driving rod 233 is a worm (not shown in the figure) meshing with the worm wheel; a snap ring is provided on the connecting portion 12, and the rod body of the driving rod 233 is inserted into the snap ring, and the driving rod 233 rotates in the snap ring. Furthermore, the number of snap rings can be multiple. The driving rod 233 rotates, and the rotating disk 231 is driven to rotate through the worm gear transmission, and the self-locking characteristics of the worm gear can be used to ensure that the position of the movable ball group 26 is fixed after it is ejected, and no rebound occurs.

[0043] In the present invention, a driving mechanism 23 is provided, including a rotating disk 231 arranged at the center of the connecting portion 12, a plurality of connecting rods 232 arranged on the surface of the rotating disk 231, and a driving rod 233 arranged on the other side of the rotating disk 231; the plurality of connecting rods 232 are arranged circumferentially, and the other ends of the connecting rods 232 are connected to the movable ball group 26. By controlling the driving rods 233 to drive the rotating disk 231 to rotate, the movable ball groups 26 on the first ball racks 21 or the second ball racks 22 can be synchronously driven to pop out, and the movable ball groups 26 that have reached the specified position can be fixed, thereby achieving the fixation of the wire 3.

[0044] In the present invention, the centers of the movable ball group 26 and the several balls on the fixed ball group 25 in the pop-up state are on the same circle, and the inner end points of the several balls form a circle, the diameter of which matches the diameter of the wire 3, or the diameter is smaller than the diameter of the wire 3, so that the wire 3 is squeezed more tightly and fixed.

[0045] like Figure 2 As shown, the telescopic mechanism 13 includes: a plurality of guide rails 131 arranged on the support portion 11, and a plurality of collars 132 arranged on the guide rails 131; there are two collars 132 on the same guide rail 131, and the two collars 132 are respectively arranged on the two sides of the connecting portion 12, with a gap left. It is worth noting that the guide rail 131 is a horizontally arranged cylinder, and the connecting portion 12 is movably connected to the guide rail 131 through the collar 132. Furthermore, bolts are arranged on the surface of the collar 132, and the lower end of the bolts abuts against the surface of the guide rail 131, which can fix the position of the connecting portion 12 at a suitable position.

[0046] Furthermore, the outer surfaces of several balls on the first ball rack 21 or the second ball rack 22 are provided with several regularly distributed anti-roll grooves, and the first ball rack 21 or the second ball rack 22 is also provided with an anti-roll mechanism, including: a strip-shaped anti-roll belt, and several magnets (not shown in the figure) arranged on the surface of the anti-roll belt; the positions and shapes of the several magnets correspond to the anti-roll grooves. The shape of the anti-roll groove is preferably hemispherical, evenly distributed on the surface of the ball, and the outer edge of the anti-roll groove is provided with a chamfer to prevent sharp edges from scratching the outer insulation layer of the wire 3. The magnet sinks into the anti-roll groove and is magnetically adsorbed with the ball, thereby fixing the ball, preventing the wire 3 from being subjected to the radial force of the wire 3 after being fixed, causing the ball to rotate, and then the radial position of the wire 3 moves.

[0047] like Figure 6 As shown, the present invention also provides a wire holding method, comprising the following steps: S1. Pass a plurality of electric wires 3 through the first ball rack 21 and through the second ball rack 22 respectively.

[0048] S2. Use the driving structure to control the movable ball group 26 on the first ball rack 21 to pop out, so that the balls in the first ball rack 21 contact the wires 3 to perform initial positioning on the wires 3.

[0049] S3, one end of the wire 3 passing through the second ball rack 22 is connected to the tensioner, and the first ball rack 21 is moved back and forth on the guide rail 131 along the radial direction of the wire 3. After the wire 3 is straightened, the tension is adjusted by the tensioner to ensure that different wires 3 are parallel to each other, and the driving structure is used to control the movable ball group 26 on the second ball rack 22 to pop out and fix the wire 3.

[0050] The wire 3 in step S1 can be a bundle of multiple thin wires 3 or a single wire 3 / cable. When passing through the first ball rack 21 and the second ball rack 22, the movable ball set 26 is in a retracted state, and the wire 3 can easily pass through the first ball rack 21 and the second ball rack 22.

[0051] Furthermore, during the laying of the wire 3 / cable, the wire 3 can be first passed through the first ball rack 21 and the second ball rack 22, and then continued to be laid forward, with a wire 3 retaining rack set in the middle as needed, during which the movable ball group 26 is always in a retracted state. During the laying of the wire 3, the balls on the first ball rack 21 and the second ball rack 22 are connected with the surface of the wire 3 in a rolling manner, which will not hinder the laying of the wire 3, and can assist the conveying process of the wire 3 during the laying, specifically, the friction contact between the wire 3 and the partial plane is converted into rolling contact with the balls, reducing the friction force of the wire 3 pulling, reducing the difficulty of laying, and can also ensure the relative position between multiple wires 3, reducing the problems of twisting and entanglement.

[0052] After the initial positioning of the wire 3 in step S2, the position of the wire 3 in the wire 3 holder can be kept relatively stable, which is convenient for the subsequent steps of straightening the wire 3 and adjusting the tension, solves the problem of random changes in the position of the wire 3 during the straightening and tension adjustment of the wire 3 in step S3, and reduces the difficulty of the operation of step S3.

[0053] In step S3, the tensioner is preferably an electronic tensioner, and a fixed tension value is set. The specific usage steps are: fix one end of the wire 3 on the tensioner, and control the tightness of the wire 3 according to the adjustment. At the same time, control the first ball rack 21 to reciprocate on the guide rail 131 along the radial direction of the wire 3, and use the balls to contact the surface of the wire 3 and reciprocate to straighten the twisted parts of the wire 3. After reaching the set tension value, use the driving structure to control the movable ball group 26 on the second ball rack 22 to pop out and fix the wire 3.

[0054] Furthermore, after the wire 3 is fixed, an anti-roll mechanism is used to connect the wires 3 to the first ball rack 21 or the second ball rack 22 so that the balls no longer roll. Preferably, the anti-roll mechanism is connected to the balls on the second ball rack 22. It is ensured that the position of the wire 3 will not change due to the rotation of the balls, thereby ensuring the stability of the tension of the wire 3, that is, the multiple wires 3 are parallel to each other. This layout of electrical parallelism helps to evenly distribute the electromagnetic field and reduce electromagnetic interference between the wires 3. The parallel arrangement of the wires 3 helps air circulation, thereby improving the heat dissipation efficiency and avoiding aging or damage of the wires 3 due to overheating.

[0055] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
