Description

Technical Field

[0001] The utility model relates to the technical field of wire shaft insulators, in particular to a wire shaft insulator fastening kit. Background Art

[0002] When laying cables, they are generally straightened and fixed by tie ropes. However, existing bobbin insulator tie ropes consist of tie rope brackets that can be installed on walls or cable poles and bobbin insulators for supporting cables. When the cable passes through the tie rope, it is generally close to the bobbin insulator, and then the cable and the bobbin insulator are tied and fixed by winding with wire.

[0003] In order to fix the cable on the insulator in the existing device, clamping components for clamping the cable are provided at both ends of the top of the insulator. However, the existing device only clamps the cable by the clamping components at both ends without fixing the middle of the cable. When the middle of the cable is subjected to force, the two ends of the cable will be driven to move toward the middle, so that the two ends of the cable slide in the clamping components, accelerating the wear of the clamping components, thereby reducing the service life of the device. At the same time, the cable is clamped only by two clamping components. When the clamping components are worn and the clamping of the cable is unstable, the cable is very likely to shake in the clamping components, which may increase the risk of the cable detaching from the fastening component and falling off. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a bobbin insulator fastening kit, which can double-fix the cable by two groups of C-shaped elastic clamping parts groups arranged at intervals and staggered and clamping components located at both ends of the two groups of C-shaped elastic clamping parts groups. On the one hand, it can avoid as much as possible the situation that the two ends of the cable move toward the middle when the middle part of the cable is subjected to force, and at the same time, it can avoid as much as possible the situation that the cable falls off the fastening kit when the clamping component is worn, thereby improving the stability of the fastening kit when fixing the cable.

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

[0006] A bobbin insulator fastening kit is installed on the bobbin insulator, comprising a fastening sleeve sleeved between the upper and lower ribs of the bobbin insulator and a cable fixing assembly arranged on one side of the fastening sleeve; the cable fixing assembly comprises a mounting base fixedly connected to one side of the fastening sleeve, a clamping subassembly symmetrically arranged at the left and right ends of the mounting base, and two groups of C-shaped elastic clamping parts arranged alternately between the two clamping subassemblies and fixed to the mounting base; the clamping subassembly comprises a mounting ring fixedly arranged at the end of the mounting base, a pair of elastic clamping plates symmetrically fixed inside the mounting ring up and down, and a ring movably sleeved outside the two elastic clamping plates and sliding along the length direction of the mounting base; the ring is arranged on the outside of the mounting ring and the inner diameter increases uniformly from the outside to the inside; the outer surfaces of the two elastic clamping plates are both in contact with the inner wall of the ring.

[0007] More preferably, each group of the C-shaped elastic clamping member groups includes a plurality of C-shaped elastic clamping rings distributed in an array, and the opening directions of the C-shaped elastic clamping rings in the two groups of C-shaped elastic clamping member groups are opposite.

[0008] More preferably, a support seat for strengthening support is fixedly connected between the fastening sleeve and the mounting base.

[0009] More preferably, the mounting base has sliding grooves symmetrically extending through the left and right ends along the length direction, a slider is slidably arranged in each of the sliding grooves, and the two groups of rings in the clamping subassemblies are respectively fixedly connected to the corresponding sliders; limit blocks are symmetrically fixed on the front and rear sides of the sliders, and the sliding groove has a number of limit grooves matching the limit blocks on both side walls along the length direction.

[0010] The utility model has the following beneficial effects:

[0011] 1. Due to the elastic force of the elastic clamping plates, the two elastic clamping plates are kept in contact with the inner wall of the ring on one side away from each other. Since the inner diameter of the ring increases uniformly from the outside to the inside, when the ring moves outward, the distance between the clamping ends of the two elastic clamping plates will decrease, thereby facilitating the clamping and fixing of cables with different diameters.

[0012] 2. The utility model clamps the two ends of the cable through two clamping subassemblies, and two sets of C-shaped elastic clamping member groups arranged at intervals further clamp and fix the middle of the cable. When the clamping subassembly is worn, the cable will also be clamped by a number of C-shaped elastic clamping rings, thereby enhancing the stability of the cable when it is fixed, thereby reducing the possibility of the cable falling off from the fastening kit, and at the same time avoiding as much as possible when the middle of the cable is stressed, the two ends of the cable move closer to each other to cause wear between the clamping subassembly, thereby improving the service life of the device;

[0013] 3. The utility model arranges two groups of C-shaped elastic clamping parts with opposite opening directions at intervals, which can avoid as much as possible the possibility of the cable falling out of the opening when the opening directions of the C-shaped elastic clamping rings are consistent, thereby improving the stability of the fastening kit.

[0021] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] A bobbin insulator fastening kit is installed on a bobbin insulator 1, comprising a fastening sleeve 2 sleeved between the upper and lower umbrella edges of the bobbin insulator 1 and a cable fixing assembly 3 arranged on one side of the fastening sleeve 2; the cable fixing assembly 3 comprises a mounting base 31 fixedly connected to one side of the fastening sleeve 2, a clamping subassembly 32 symmetrically arranged at the left and right ends of the mounting base 31, and two groups of C-shaped elastic clamping member groups spaced between the two clamping subassemblies 32 and fixed to the mounting base 31; the clamping subassembly 32 comprises a mounting ring 321 fixedly arranged at the end of the mounting base 31, a pair of elastic clamping plates 322 symmetrically fixed inside the mounting ring 321, and a ring 323 movably sleeved outside the two elastic clamping plates 322 and sliding along the length direction of the mounting base 31; the ring 323 is arranged on the outside of the mounting ring 321 and the inner diameter increases uniformly from the outside to the inside; the outer surfaces of the two elastic clamping plates 322 are both in contact with the inner wall of the ring 323.

[0023] Due to the elastic force of the elastic clamping plates 322, the two elastic clamping plates 322 are kept in contact with the inner wall of the ring 323 on the side away from each other. Since the inner diameter of the ring 323 increases uniformly from the outside to the inside, when the ring 323 moves outward, the distance between the clamping ends of the two elastic clamping plates 322 will decrease, thereby facilitating the clamping and fixing of cables of different diameters. The two clamping subassemblies 32 are used to clamp the two ends of the cable, and the two sets of C-shaped elastic clamping parts arranged at intervals further clamp and fix the middle part of the cable. When 32 is worn, the cable will also be clamped by several C-shaped elastic clamping rings 33, so as to enhance the stability of the cable when it is fixed, thereby reducing the possibility of the cable falling off the fastening kit, and at the same time avoiding as much as possible the wear between the clamping subassembly 32 caused by the two ends of the cable moving closer to each other when the middle of the cable is subjected to force, thereby improving the service life of the device; in this device, the clamping end of the elastic clamp 322 is tilted from the outside to the inside, and the inner diameter of the mounting ring 321 is greater than or equal to the maximum inner diameter of the ring 323.

[0024] As a possible implementation of this solution, preferably, each group of the C-shaped elastic clamping element groups includes a number of C-shaped elastic clamping rings 33 distributed in an array; by arranging two groups of C-shaped elastic clamping element groups with opposite opening directions at intervals, the possibility of the cable disengaging from the opening when the opening directions of the C-shaped elastic clamping rings 33 are the same can be avoided as much as possible, so as to improve the stability of the fastening kit.

[0025] As a possible implementation of this solution, preferably, a support base 4 for strengthening the support is also fixedly connected between the fastening sleeve 2 and the mounting base 31; the setting of the support base 4 can further enhance the firmness when the mounting base 31 and the fastening sleeve 2 are fixed.

[0026] As a possible implementation of this solution, preferably, sliding grooves 311 are symmetrically formed through the left and right ends of the mounting base 31 along the length direction, and a slider 312 is slidably arranged in each sliding groove 311. The sleeves 323 in the two clamping sub-assemblies 32 are respectively fixedly connected to the corresponding sliders 312; limiting blocks 3121 are symmetrically fixed on the front and rear surfaces of the slider 312, and a number of limiting grooves 3111 adapted to the limiting blocks 3121 are formed on both side walls of the sliding groove 311 along the length direction; through the interference fit between the limiting blocks 3121 and the limiting grooves 3111, the slider 312 is fixed inside the sliding groove 311 after the sleeve 323 moves to a suitable position. At the same time, since the sliding groove 311 is formed through, rainwater will not accumulate in the sliding groove 311, and the influence of rainwater on the service life of the slider 312 can be reduced as much as possible.

[0027] The working principle of this device is as follows:

[0028] Move the two sleeves 323 to the side close to each other. At this time, the distance between the two elastic clamping plates 322 is the largest. Pass the cable through the two clamping sub-assemblies 32, sequentially buckle the two groups of C-shaped elastic clamping element groups on the outer side of the cable, tighten the cable at both ends, and then slide the two sleeves 3223 away from each other until the two elastic clamping plates 322 clamp the cable from the upper and lower sides and stop. At this time, the two limiting blocks 3121 on the slider 312 are respectively in interference fit with the corresponding limiting grooves 3111.

[0029] The above are only the specific implementation manners of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
