Description

Technical Field

[0001] The present application relates to the technical field of cable wiring, and in particular to a cable limiting structure based on a universal ball structure. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. During the installation process, a limiting structure is generally required to limit the cable to prevent the cable from falling off the wall or the inner wall of the distribution box.

[0003] In current cable management systems, cable limitation and guidance are usually achieved through fixed guide grooves or pulleys. Although these traditional methods can achieve cable limitation to a certain extent, due to the fixed structure of the fixed guide grooves or pulleys, users cannot adapt to multi-directional and multi-angle cable wiring requirements during installation. Utility Model Content

[0004] The utility model aims to solve or at least alleviate the problem that the existing cable limiting device has a fixed structure, cannot adapt to the requirements of multi-directional and multi-angle cable wiring, and is inconvenient for users to use.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cable limiting structure based on a universal ball structure includes a base, a fixing structure for fixing the base is installed on the base, a mounting groove is opened on the upper surface of the base, a ball bearing is embedded in the inner cavity of the mounting groove, the outer ring of the ball bearing is in contact with the inner wall of the mounting groove and is fixedly connected to the inner wall of the mounting groove, and a first connecting structure for fixing the cable is installed on one end of the inner ring of the ball bearing located outside the inner cavity of the mounting groove.

[0007] By adopting the above technical solution, the base is fixed in a suitable position by a screw, and the outer ring of the ball bearing is embedded in the base and fixedly connected to the base. When in use, the cable that needs to be limited can be fixed to the inner ring of the ball bearing through the first connecting structure or the second connecting structure. Since the inner and outer rings of the ball bearing are rotatably connected by the ball, the user can adjust the direction of the cable by rotating the inner ring of the ball bearing to flexibly route the cable, thereby avoiding as much as possible the problem that the existing cable limiting device has a fixed structure, cannot adapt to the requirements of cable routing in multiple directions and angles, and is inconvenient for users.

[0008] Optionally, the fixing structure includes through holes opened at four corners of the base, and a screw is passed through the inner cavity of each through hole. The screw passes through the through hole and is screwed to the external structure.

[0009] By adopting the above technical solution, after the user determines the fixing position of the base, four screws can be passed through the base through the through holes and screwed to the external structure to fix the base.

[0010] Optionally, the inner cavity depth of the mounting groove is greater than the thickness of the ball bearing, and a gap is left between one end of the ball bearing located in the inner cavity of the mounting groove and the bottom wall of the inner cavity of the mounting groove.

[0011] By adopting the above technical solution, a gap is left between one end of the ball bearing located in the inner cavity of the installation groove and the bottom wall of the inner cavity of the installation groove, so that the inner ring of the ball bearing can fit closely with the inner wall of the installation groove, thereby hindering the rotation of the inner ring of the ball bearing.

[0012] Optionally, the outer surface of the ball bearing is electroplated with a wear-resistant layer, and the wear-resistant layer is a metal chromium layer.

[0013] By adopting the above technical solution, metal chromium is electroplated on the outer surface of the ball bearing to form a wear-resistant layer, which is used to improve the wear resistance of the ball bearing, thereby greatly improving the service life of the overall structure.

[0014] Optionally, the first connecting structure includes a fixing plate fixedly connected to the end of the inner ring of the ball bearing along the diameter direction of the ball bearing, a limiting ring with an arc-shaped structure is provided above the fixing plate, both ends of the limiting ring extend outward to form an overlapping portion, a screw is passed through the overlapping portion, and the screw passes through the overlapping portion and is threadedly connected to the end of the fixing plate.

[0015] By adopting the above technical solution, when in use, firstly, the arc-shaped limit ring is sleeved on the cable, and then after the overlapping part is aligned with the fixing plate, the limit ring is fixed to the fixing plate by screws, thereby achieving the fixing of the cable.

[0016] Optionally, a rubber pad is provided in the inner cavity of the limiting ring of the arc-shaped structure, and the outer wall of the rubber pad is bonded to the inner wall of the limiting ring.

[0017] By adopting the above technical solution, a rubber pad is provided to protect the cable in the inner cavity of the limiting ring, so as to avoid the problem of hard squeezing between the inner wall of the limiting ring and the cable, and the damage of the stagnant cable.

[0018] Optionally, a second connecting structure for replacing the first connecting structure is installed on one end of the inner ring of the ball bearing located outside the inner cavity of the installation groove, and the second connecting structure includes two turntables symmetrically arranged on both sides of the inner ring of the ball bearing, and both turntables have annular clamping grooves on their circumferences, and the inner cavity depth and inner cavity width of the clamping groove on one side of the turntable gradually increase to the inner cavity depth and inner cavity width on the other side of the turntable.

[0019] By adopting the above technical solution, two turntables are set up to clamp and fix the cable through the clamping grooves on the adjacent sides of the two turntables. Since the inner cavity depth and inner cavity width of the clamping groove on one side of the turntable gradually increase to the inner cavity depth and inner cavity width on the other side of the turntable, the depth of the clamping groove at the contact position with the cable can be adjusted by rotating the turntable, which facilitates the clamping and fixing of cables of different diameters.

[0020] Optionally, a limit bolt rotatably connected to the turntable is provided at the center of the two turntables. The limit bolt passes through the turntable and is threadedly connected to the end of the inner ring of the ball bearing.

[0021] By adopting the above technical solution, after the cable is clamped by the turntable, the user can screw the limit bolt into the end of the inner ring of the ball bearing, and the turntable can be fixed by clamping the limit bolt cap and the end of the inner ring of the ball bearing.

[0022] In summary, the beneficial effects of this application are as follows:

[0023] The present application achieves a coordinated arrangement among structures such as a base, a mounting groove, a ball bearing and a limiting ring. The outer ring of the ball bearing is embedded in the base through the mounting groove and fixedly connected to the base. When in use, the cable is fixed to the inner ring of the ball bearing through the limiting ring. Since the inner and outer rings of the ball bearing can rotate relative to each other, the user can adjust the direction of the cable by rotating the inner ring of the ball bearing to flexibly route the cable, thereby avoiding as much as possible the problem that the existing cable limiting device has a fixed structure, cannot adapt to the requirements of cable routing in multiple directions and angles, and is inconvenient for users.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] See also Figure 1-3The cable limiting structure based on the universal ball structure includes a base 1, on which is mounted a fixing structure for fixing the base 1. When in use, the user can fix the base 1 at a position where the cable needs to be limited through the fixing structure.

[0030] A mounting groove 2 is provided on the upper surface of the base 1, and a ball bearing 5 with an outer ring diameter equal to the inner diameter of the mounting groove 2 is embedded in the inner cavity of the mounting groove 2. The outer ring of the ball bearing 5 fits the inner wall of the mounting groove 2 and is fixedly connected to the inner wall of the mounting groove 2. Since the outer ring and the inner ring of the ball bearing 5 are connected by a ball sliding connection, when the outer ring of the ball bearing 5 is fixed, its inner ring can rotate freely in the inner cavity of the outer ring.

[0031] A first connecting structure for fixing the cable is installed on one end of the inner ring of the ball bearing 5 located outside the inner cavity of the installation groove 2. After the user completes the installation of the base 1, the cable can be fixed to the inner ring end of the ball bearing 5 through the first connecting structure, so that the free rotation of the inner ring of the ball bearing 5 can drive the cable to rotate synchronously, and the cable can be flexibly routed in multiple directions.

[0032] Reference Figure 1 The fixing structure includes through holes 3 opened at four corners of the base 1, and a screw 4 is inserted into the inner cavity of each through hole 3. The screw 4 passes through the through hole 3 and is screwed to the external structure. When the user determines the fixing position of the base 1, the four screws 4 can pass through the base 1 through the through holes 3 and screwed to the external structure to fix the base 1.

[0033] Reference Figure 1 The inner cavity depth of the mounting groove 2 is greater than the thickness of the ball bearing 5, and a gap is left between one end of the ball bearing 5 located in the inner cavity of the mounting groove 2 and the inner cavity bottom wall of the mounting groove 2. The gap is left between one end of the ball bearing 5 located in the inner cavity of the mounting groove 2 and the inner cavity bottom wall of the mounting groove 2, so that the inner ring of the ball bearing 5 fits closely with the inner wall of the mounting groove 2, thereby hindering the rotation of the inner ring of the ball bearing 5.

[0034] Reference Figure 2 The outer surface of the ball bearing 5 is electroplated with a wear-resistant layer 6, which is a metal chromium layer. The wear-resistant layer 6 is formed by electroplating metal chromium on the outer surface of the ball bearing 5 to improve the wear resistance of the ball bearing 5, thereby greatly improving the service life of the overall structure.

[0035] Reference Figure 2The first connection structure includes a fixing plate 7 fixedly connected to the inner ring end of the ball bearing 5 along the diameter direction of the ball bearing 5, and a limiting ring 8 with an arc structure is arranged above the fixing plate 7. Both ends of the limiting ring 8 extend outward to form a lap joint, and a screw 9 is passed through the lap joint. The screw 9 penetrates the lap joint and is screwed to the end of the fixing plate 7. When in use, the limiting ring 8 with an arc structure is firstly sleeved on the cable, and then the lap joint is aligned with the fixing plate 7, and the limiting ring 8 is fixed to the fixing plate 7 by the screw 9, so that the fixing work of the cable can be realized.

[0036] Reference Figure 2 A rubber pad 10 is provided in the inner cavity of the arc-shaped limit ring 8, and the outer wall of the rubber pad 10 is bonded to the inner wall of the limit ring 8. The rubber pad 10 is provided to protect the cable in the inner cavity of the limit ring 8, and to avoid the problem of hard squeezing between the inner wall of the limit ring 8 and the cable, and the problem of damage to the stagnant cable.

[0037] Reference Figure 3 The second connection structure for replacing the first connection structure is installed on one end of the inner ring of the ball bearing 5 located outside the inner cavity of the installation groove 2. The second connection structure includes two turntables 11 symmetrically arranged on both sides of the inner ring of the ball bearing 5. The two turntables 11 are provided with annular clamping grooves 12 on the circumference. The inner cavity depth and inner cavity width of the clamping groove 12 on one side of the turntable 11 gradually increase to the inner cavity depth and inner cavity width on the other side of the turntable 11. The two turntables 11 are arranged to clamp and fix the cable through the clamping grooves on the adjacent sides of the two turntables 11. Since the inner cavity depth and inner cavity width of the clamping groove 12 on one side of the turntable 11 gradually increase to the inner cavity depth and inner cavity width on the other side of the turntable 11, the depth of the clamping groove 12 at the contact position with the cable can be adjusted by rotating the turntable 11, so as to facilitate the clamping and fixing of cables of different diameters.

[0038] Reference Figure 3 The centers of the two turntables 11 are each provided with a limit bolt 13 rotatably connected to the turntable 11. The limit bolt 13 penetrates through the turntable 11 and is screwed to the inner end of the ball bearing 5. After the cable is clamped by the turntable 11, the user can screw the limit bolt 13 into the inner end of the ball bearing 5, and the turntable 11 is clamped by the bolt cap of the limit bolt 13 and the inner end of the ball bearing 5 to fix the turntable 11.

[0039] Embodiment 1, when in use, first fix the base 1 in a suitable position by the screw 4, then put the limiting ring 8 on the cable to be fixed, and align the overlapping parts formed by the extension of the two ends of the limiting ring 8 with the end of the fixing plate 7 fixedly connected to the inner ring end of the ball bearing 5, and fix the limiting ring 8 on the fixing plate 7 by the screw 9 to complete the cable limiting work.

[0040] Embodiment 2, when in use, first fix the base 1 in a suitable position by the screw rod 4, then rotate the two turntables 11 symmetrically installed at the outer ring end of the ball bearing 5, adjust the inner cavity depth and inner cavity width of the clamping groove 12 opened on the adjacent sides of the two turntables 11 to adapt to the size of the cable, after the adjustment is completed, pass the cable through the inner cavity of the clamping groove 12 between the two turntables 11, and screw the limit bolt 13 into the inner ring end of the ball bearing 5, and clamp the turntable 11 together through the bolt cap of the limit bolt 13 and the inner ring end of the ball bearing 5 to fix the turntable 11, so as to complete the cable limiting work, which is convenient for users to limit and fix cables of different sizes.

[0041] The implementation principle of the present application is as follows: the base 1 is fixed in a suitable position by a screw rod 4, and the outer ring of the ball bearing 5 is embedded in the base 1 and fixedly connected to the base 1. When in use, the cable that needs to be limited can be fixed on the inner ring of the ball bearing 5 through the first connecting structure or the second connecting structure. Since the inner and outer rings of the ball bearing 5 are rotatably connected by balls, the user can adjust the direction of the cable by rotating the inner ring of the ball bearing 5 to flexibly route the cable, thereby avoiding as much as possible the problem that the existing cable limiting device has a fixed structure, cannot adapt to the cable routing requirements in multiple directions and angles, and is inconvenient for users to use.
