Description

Technical Field

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

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

[0003] Currently, there are some deficiencies in the retention and management of wires in the prior art:

[0004] 1. When arranging multiple flexible wires, generally, cable ties are used to tie multiple wires into a bundle to make the wire distribution more regular. However, due to the special material problems of flexible wires, they are prone to twisting and entanglement, resulting in a non-parallel layout among multiple wires in a bundle. This layout will cause uneven distribution of the electromagnetic field between wires, increase the electromagnetic interference between wires, and affect the stability and accuracy of signal transmission.

[0005] 2. Multiple non-parallel arranged flexible wires have large-area contact, which hinders air circulation and reduces the heat dissipation efficiency. Long-term overheating will cause wire aging or damage.

[0006] 3. After tying multiple flexible wires into a bundle, due to the easy-bending characteristics of the wires, the actual lengths of the wires are significantly different under the overall length. In the case of frequent movement of the connected devices, this length difference causes uneven longitudinal stress between the wires, and some wires may undergo longitudinal displacement, thereby weakening the stable retention effect of the wires.

[0007] Therefore, it is necessary to provide a wire retainer and a retaining method to solve the above technical problems. Summary of the Invention

[0019] In a preferred embodiment of the present invention, a number of anti-rolling grooves are regularly distributed on the outer surfaces of a number of ball bearings on the first ball bearing holder or the second ball bearing holder.

[0025] The present invention solves the defects in the background technology, and the present invention has the following beneficial effects:

[0026] (1) The present invention provides a wire holder, which is provided with a frame body, a number of wire threading components arranged in the frame body, and the number of wire threading components are arranged circumferentially. Each wire threading component is a detachable structure, including: a first ball bearing holder and a second ball bearing holder. The central axes of the wire, the first ball bearing holder and the second ball bearing holder coincide. If the several wires in the wire holder are straight, then these wires are parallel to each other. This layout helps to evenly distribute the electromagnetic field, reduce the electromagnetic interference between the wires, and the parallel arranged wires help the air circulation, thereby improving the heat dissipation efficiency and avoiding wire aging or damage caused by overheating.

[0027] (2) In the use of some flexible wires in the present invention, such as in the use scenarios of drag chain cables, tow cables, mobile cables, robot cables, etc., one end of the wire / cable will move continuously. By bundling a number of wires / cables into one bundle with the wire holder of the present invention, there is space between each wire / cable, which can reduce the mutual friction and damage caused by vibration in a dynamic environment.

[0028] (3) In the present invention, a driving mechanism is provided, which includes a rotating disk disposed at the center of the connecting portion, a plurality of connecting rods disposed on the surface of the rotating disk, and a driving rod disposed on the other side of the rotating disk; the plurality of connecting rods are circumferentially arranged, and the other ends of the connecting rods are connected to the movable ball group. By controlling the driving rod to drive the rotating disk to rotate, the movable ball groups on a plurality of first ball holders or second ball holders can be synchronously ejected, and the movable ball groups reaching the specified positions can be fixed, thereby realizing the fixing of the wire.

[0029] (4) In the present invention, an anti-rolling mechanism is provided, which includes: a strip-shaped anti-rolling belt, and a plurality of magnets disposed on the surface of the anti-rolling belt; and a plurality of regularly distributed anti-rolling grooves are provided on the outer surfaces of a plurality of balls on the first ball holder or the second ball holder, and the positions and shapes of the plurality of magnets are correspondingly arranged with respect to the anti-rolling grooves. The cooperation between the anti-rolling mechanism and the anti-rolling grooves achieves the fixing of the balls by inserting the magnets into the anti-rolling grooves and magnetically adsorbing the balls, preventing the problem that after the wire is fixed, due to the radial force of the wire, the balls rotate, and thus the radial position of the wire moves.

[0030] (5) The present invention provides a wire holding method, which is used in cooperation with a wire holder. After the wire passes through the first ball holder and the second ball holder, the first ball holder is first used to perform an initial positioning of the wire, and then the first ball holder is controlled to reciprocate along the radial direction of the wire on the guide rail.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

Therefore, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0042] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" 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 communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0043] The present invention provides a wire holder, which is applicable to the arrangement and fixation of flexible wires / cables, and can also be used for assistance during the laying process of wires / cables.

[0044] As Figure 1 shown, the present invention provides a wire holder, including a frame body 1 and a plurality of wire threading components 2 arranged inside the frame body 1, and is characterized in that: the plurality of wire threading components 2 are arranged circumferentially, and the number of the wire threading components 2 is set according to the actual number of wires 3 / cables, preferably 3 - 6, and at the same time, a plurality of wires 3 / cables are arranged and fixed.

[0045] As Figure 2 shown, each wire threading component 2 is a detachable structure, including: a first ball bearing frame 21, a second ball bearing frame 22, and a driving mechanism 23 correspondingly arranged with the first ball bearing frame 21 and the second ball bearing frame 22; that is, the first ball bearing frame 21 and the second ball bearing frame 22 are independent, the distance between the first ball bearing frame 21 and the second ball bearing frame 22 can be adjusted, and the central axes of the first ball bearing frame 21 and the second ball bearing frame 22 coincide.

[0046] Furthermore, the central axes of the wire 3, the first ball bearing frame 21, and the second ball bearing frame 22 also coincide. If several wires 3 in the wire holder are straight, then these wires 3 are parallel to each other. This layout helps to evenly distribute the electromagnetic field, reduce the electromagnetic interference between the wires 3, and the parallel - arranged wires 3 contribute to air circulation, thereby improving the heat dissipation efficiency and avoiding the aging or damage of the wires 3 caused by overheating.

[0047] In the use of some flexible wires, such as in the use scenarios of drag chain cables, tow cables, mobile cables, robot cables, etc., one end of the wire 3 / cable will move continuously. By using the wire holder of the present invention, a plurality of wires 3 / cables are bundled into one strand, and there is space between each wire 3 / cable, which can reduce the mutual friction and damage caused by vibration in a dynamic environment.

[0048] As Figure 3As shown in the figure, both the first ball holder 21 and the second ball holder 22 include: a ring body 24, a fixed ball group 25 and a movable ball group 26 arranged inside 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 holder 21 and the second ball holder 22 are arranged along the length direction of the frame body 1, the first ball holder 21 is in the front, the second ball holder 22 is in the back, and the wire 3 first passes through the first ball holder 21 and then passes through the second ball holder 22.

[0049] It should be noted that the ring body 24 is a structure of two coaxial metal rings, and connecting ribs are arranged between the metal ring structures. The diameters of the ring bodies 24 of the first ball holder 21 and the second ball holder 22 can be the same or different, which are set according to different usage scenarios, and the present invention does not make specific limitations. Both the fixed ball group 25 and the movable ball group 26 are composed of a number of balls and corresponding ball sleeves. The sizes of the balls are the same, and all are made of steel balls. Among them, the ball sleeves of the fixed ball group 25 are 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 holder 21 or the second ball holder 22. The movable ball group 26 moves inside the ring body 24 along a fixed straight line direction, that is, the direction towards the center of the circle, to realize the change of the space inside the first ball holder 21 or the second ball holder 22, and ensure the contact and non-contact between the wire 3 and the balls inside the first ball holder 21 or the second ball holder 22, as well as the change of the extrusion degree of the balls on the surface of the wire 3.

[0050] Furthermore, the driving mechanism 23 is used to control the movement of the movable ball group 26 to realize the tightness of the contact between the balls and the surface of the wire 3, and achieve the loosening, releasing and fixing operations of the wire 3.

[0051] As Figure 5 shown, the movable ball group 26 further includes: a connecting plate 261, and a number of parallel limiting grooves 262 opened on the connecting plate 261. The length direction of the limiting grooves 262 is along the moving direction of the movable ball group 26, and the number is preferably two. Limiting rods 263 are arranged on the ring body 24 corresponding to the limiting grooves 262. The limiting rods 263 are inserted into the limiting grooves 262. The limiting rods 263 are vertically arranged and are cylinders. The outer surface of the limiting rods 263 is slidably connected to the inner wall of the limiting grooves 262. It can ensure that the movable ball group 26 only moves in the set direction and avoid deviation. A limiting plate 264 is also arranged on the ring body 24. The limiting plate 264 is a two-section structure and is slidably connected to the upper and lower surfaces of the connecting plate 261 respectively. This setting ensures that the connecting plate 261 does not move with one end high and the other end low. The combined 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 to fix the wire 3.

[0052] As Figure 2As shown in the figure, the frame body 1 includes: a support portion 11, a connecting portion 12, and a telescopic mechanism 13 disposed between the support portion 11 and the connecting portion 12; the connecting portion 12 is respectively connected to the first ball bearing holder 21 and the second ball bearing holder 22, and the telescopic mechanism 13 is used to control the first ball bearing holder 21 to move along the length direction of the frame body 1. The support portion 11 is the outermost frame structure of the frame body 1 and serves as the foundation of the entire wire 3 holder to ensure the stable installation of each component. The telescopic mechanism 13 is installed in the support portion 11, and the connecting portion 12 is installed on the telescopic mechanism 13, that is, the connecting portion 12 can move on the telescopic mechanism 13, thereby driving the first ball bearing holder 21 or the second ball bearing holder 22 to move.

[0053] Further, a triangular support leg can be provided on one side of the support portion 11, which is supported on a plane to prevent the wire 3 holder from rolling over, and mounting holes can be opened on the support leg and fixed to the plane through bolts.

[0054] As Figure 3 shown in the figure, the driving mechanism 23 includes: a rotating disk 231 disposed at the center of the connecting portion 12, a plurality of connecting rods 232 disposed on the surface of the rotating disk 231, and a driving rod 233 disposed on the other side of the rotating disk 231. The plurality of connecting rods 232 are circumferentially arranged, and the other ends of the connecting rods 232 are 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 circumferentially arranged. The rotating disk 231 is rotatably disposed at the center of the connecting portion 12, that is, at the center position of the plurality of circumferentially arranged first ball bearing holders 21 or second ball bearing holders 22. Each connecting rod 232 on the rotating disk 231 corresponds to a first ball bearing holder 21 or a second ball bearing holder 22. By rotating the rotating disk 231, the connecting rod 232 is driven to rotate, thereby driving the corresponding movable ball group 26 to move.

[0055] In one embodiment of the present invention, as Figure 4 shown in the figure, 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. The rod body of the driving rod 233 is inserted into the snap ring, and fixing holes are opened on the surface. Bolts are provided on the surface of the snap ring corresponding to the fixing holes, and the bolts are connected to the fixing holes to fix the position of the driving rod 233 (not shown in the figure). Such a design can ensure that the displacement of the driving rod 233 is within a fixed range, and further ensure that the position range of the movable ball group 26 is fixed. It should be noted that the rod body of the driving rod 233 passes through the gap between two first ball bearing holders 21 or second ball bearing holders 22, and can control the driving mechanism 23 without being blocked by the wire 3 after passing through the wire 3.

[0056] In another embodiment of the present invention, a worm gear is provided on one side of the rotating disk 231. The worm gear is coaxially arranged with the rotating disk 231. One end of the driving rod 233 is a worm (not shown in the figure) meshed with the worm gear; a snap ring is provided on the connecting portion 12. The rod body of the driving rod 233 is inserted into the snap ring, and the driving rod 233 rotates within the snap ring. Further, the number of snap rings can be multiple. When the driving rod 233 rotates, through the worm and worm gear transmission, the rotating disk 231 is driven to rotate, and by utilizing the self-locking characteristic of the worm and worm gear, the position of the movable ball group 26 after popping out can be ensured to be fixed and no rebound will occur.

[0057] In the present invention, a driving mechanism 23 is provided, which 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 in a circumferential manner, and the other ends of the connecting rods 232 are connected to the movable ball group 26. By controlling the driving rod 233 to drive the rotating disk 231 to rotate, the movable ball groups 26 on a plurality of first ball holders 21 or second ball holders 22 can be synchronously popped out, and the movable ball groups 26 reaching the specified positions can be fixed, thereby realizing the fixation of the wire 3.

[0058] In the present invention, when in the popped state, the centers of the plurality of balls of the movable ball group 26 and the fixed ball group 25 are on a circle. The inner ends of the plurality of balls form a circle, and the diameter of this circle matches the diameter of the wire 3 or is smaller than the diameter of the wire 3, so as to realize a tighter extrusion of the wire 3 and achieve fixation.

[0059] As Figure 2 shown, the telescopic mechanism 13 includes: a plurality of guide rails 131 arranged on the support portion 11, and a plurality of collar rings 132 arranged on the guide rails 131; the number of collar rings 132 on the same guide rail 131 is two, and the two collar rings 132 are respectively arranged on the two side surfaces of the connecting portion 12 with a gap left. It should be noted 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 rings 132. Further, bolts are provided on the surface of the collar rings 132, and the lower ends of the bolts abut against the surface of the guide rail 131, so as to be able to fix the position of the connecting portion 12 at a suitable position.

[0060] Further, a number of anti-rolling grooves are regularly distributed on the outer surfaces of a number of balls on the first ball cage 21 or the second ball cage 22. An anti-rolling mechanism is also provided on the first ball cage 21 or the second ball cage 22, including: a strip-shaped anti-rolling belt, and a number of magnets (not shown in the figure) provided on the surface of the anti-rolling belt; the positions and shapes of the number of magnets correspond to the anti-rolling grooves. The shape of the anti-rolling groove is preferably hemispherical, evenly distributed on the surface of the ball, and a chamfer is provided on the outer edge of the anti-rolling groove to prevent the sharp edge from scratching the outer insulating layer of the wire 3. The magnet sinks into the anti-rolling groove and magnetically adsorbs the ball, achieving the fixation of the ball, preventing the ball from rotating under the action of the radial force of the wire 3 after the wire 3 is fixed, and further preventing the problem of the radial position of the wire 3 from moving.

[0061] As Figure 6 shown, the present invention also provides a wire holding method, including the following steps:

[0062] S1. Pass a number of wires 3 through the first ball cage 21 respectively and then through the second ball cage 22.

[0063] S2. Use the driving structure to control the active ball group 26 on the first ball cage 21 to pop out, so that the balls in the first ball cage 21 contact the wire 3 and perform preliminary positioning on the wire 3.

[0064] S3. Connect one end of the wire 3 passing out of the second ball cage 22 to a tensioner. Move the first ball cage 21 reciprocally along the radial direction of the wire 3 on the guide rail 131. After straightening the wire 3, adjust the tension through the tensioner to ensure that different wires 3 are parallel to each other. Use the driving structure to control the active ball group 26 on the second ball cage 22 to pop out to fix the wire 3.

[0065] The wire 3 in step S1 can be a bundle of thin multi-strand wires 3 or a single wire 3 / cable. When passing through the first ball cage 21 and the second ball cage 22, the active ball group 26 is in a contracted state, and the wire 3 can easily pass through the first ball cage 21 and the second ball cage 22.

[0066] Further, during the laying process of the wire 3 / cable, the wire 3 can be first passed through the first ball cage 21 and the second ball cage 22, and then continue to be laid forward. A wire holder can be set in the middle as needed. During this period, the active ball group 26 is always in a contracted state. During the laying process of the wire 3, the balls on the first ball cage 21 and the second ball cage 22 are in rolling connection with the surface of the wire 3, which will not hinder the laying of the wire 3. And during the laying, it can assist the conveying process of the wire 3. Specifically, it converts the frictional contact between the wire 3 and a part of the plane into rolling contact with the balls, reduces the frictional force of the wire 3 being pulled, reduces the laying difficulty, and at the same time can ensure the relative positions between multiple wires 3 and reduce the problems of twisting and entanglement.

[0067] After the initial positioning of the wire 3 in step S2, the position of the wire 3 in the wire retainer 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 the random change of 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 in step S3.

[0068] In step S3, the tensioner is preferably an electronic tensioner, and a fixed tension value is set. The specific operation steps are as follows: Fix one end of the wire 3 on the tensioner, adjust and control the tightness of the wire 3 accordingly. At the same time, control the first ball holder 21 to reciprocate along the radial direction of the wire 3 on the guide rail 131, and use the balls to contact the surface of the wire 3. The reciprocating movement straightens the twisted part 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 holder 22 to pop out to fix the wire 3.

[0069] Furthermore, after the wire 3 is fixed, an anti-rolling mechanism is connected to several balls on the first ball holder 21 or the second ball holder 22 to prevent the balls from rolling. It is preferably to connect the anti-rolling mechanism to the balls on the second ball holder 22. Ensure 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 mutual parallelism of multiple wires 3. This electrically parallel layout helps to evenly distribute the electromagnetic field, reduce the electromagnetic interference between the wires 3, and the parallel arranged wires 3 contribute to air circulation, thereby improving the heat dissipation efficiency and avoiding the aging or damage of the wires 3 caused by overheating.

[0070] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea 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.
