[0021] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Embodiment 1:

[0023] As Figure 1 shown, the embodiment of the present utility model provides a cable insulation repair device for repairing a damaged insulation layer of a cable. The cable insulation repair device includes a first handle 1 and a second handle 2. A first support frame 5 is fixed to the front end of the first handle 1. A first cable accommodating cavity is formed inside the first support frame 5, and the first support frame 5 is used to lock the end of the first broken section of the cable to be repaired in the first cable accommodating cavity. The rear end of the first handle 1 forms a gripping portion of the first handle 1. Among them, the cable to be repaired includes a first broken section and a second broken section. The middle of the second handle 2 is hinged to the middle of the first handle 1, and a second support frame 6 is fixed to the front end of the second handle 2. The second support frame 6 is arranged corresponding to the first support frame 5. A second cable accommodating cavity is formed inside the second support frame 6, and the second support frame 6 is used to lock the end of the second broken section of the cable to be repaired in the second cable accommodating cavity. The rear end of the second handle 2 forms a gripping portion of the second handle 2. After squeezing the gripping portion of the first handle 1 and the gripping portion of the second handle 2, the front ends of the first handle 1 and the second handle 2 approach each other, so as to drive the first support frame 5 and the second support frame 6 to approach and contact each other.

[0024] It can be understood that the first support frame 5 and the second support frame 6 are tubular structures.

[0025] In some examples, the size of the first cable accommodating cavity matches the outer diameter size of the end of the first broken section of the cable to be repaired; the size of the second cable accommodating cavity matches the outer diameter size of the end of the second broken section of the cable to be repaired.

[0026] The fact that the size of the first cable accommodating cavity matches the outer diameter size of the end of the first broken section of the cable to be repaired means that the size of the first cable accommodating cavity is substantially the same as the outer diameter size of the end of the first broken section of the cable to be repaired. In this way, after placing the end of the first broken section of the cable to be repaired in the first cable accommodating cavity, the inner wall of the first cable accommodating cavity can be in close contact with the outer wall of the end of the first broken section, so as to ensure the locking effect of the first support frame 5 on the end of the first broken section of the cable to be repaired.

[0027] Similarly, the fact that the size of the second cable accommodating cavity matches the outer diameter size of the end of the second broken section of the cable to be repaired means that the size of the second cable accommodating cavity is substantially the same as the outer diameter size of the end of the second broken section of the cable to be repaired, which can make the inner wall of the second cable accommodating cavity completely in close contact with the outer wall of the end of the second broken section of the cable to be repaired, and can ensure the locking effect of the second support frame 6 on the end of the second broken section of the cable to be repaired.

[0028] Exemplarily, the inner wall of the first cable accommodating cavity is a smooth inner wall, and the inner wall of the second cable accommodating cavity is a smooth inner wall, which can avoid damaging the surface of the cable to be repaired by the inner walls of the first cable accommodating cavity and the second cable accommodating cavity.

[0029] Exemplarily, as Figure 1 shown, the first handle 1 and the second handle 2 are hinged through a connecting member 4.

[0030] Exemplarily, the first handle 1 and the second handle 2 have the same length, and the distance from the connecting member 4 to the first support frame 5 is equal to the distance from the connecting member 4 to the second support frame 6. In this way, when operating the holding parts of the first handle 1 and the second handle 2, the movement amplitudes of the first support frame 5 and the second support frame 6 are equal.

[0031] The axis of the first cable accommodating cavity and the axis of the second cable accommodating cavity are on the same straight line. After heating the insulating layer of the cable to be repaired, pinch the holding parts of the first handle 1 and the second handle 2 to make the first support frame 5 contact the second support frame 6, so as to lap and hot-melt repair the insulating layers at the ends of the first broken segment and the second broken segment of the cable to be repaired into one body.

[0032] It can be understood that after heating the insulating layer of the cable to be repaired and making the first support frame 5 contact the second support frame 6, the first cable accommodating cavity and the second cable accommodating cavity are interconnected. Therefore, the insulating layers at the ends of the first broken segment and the second broken segment can be thermally integrated into one body in the above-mentioned first cable accommodating cavity and the second cable accommodating cavity, so as to realize the repair of the insulating layer of the cable to be repaired. Compared with the prior art, this cable insulating repair device repairs the insulating layer of the cable by hot melting, so as to replace the repair of the cable with insulating tape in the prior art.

[0033] Therefore, the cable insulation repair device provided by the embodiment of the utility model can lock the end of the first broken section of the cable to be repaired in the first cable accommodating cavity of the first support frame 5 and the end of the second broken section of the cable to be repaired in the second cable accommodating cavity of the second support frame 6 by fixing the first support frame 5 at the front end of the first handle 1 and fixing the second support frame 6 at the front end of the second handle 2. By making the first handle 1 and the second handle 2 hinged, after pinching the gripping part of the first handle 1 and the gripping part of the second handle 2, the first support frame 5 can be brought into contact with the second support frame 6, so that the first cable accommodating cavity and the second cable accommodating cavity are interconnected, and the insulation layer of the end of the first broken section of the cable to be repaired and the insulation layer of the end of the second broken section of the cable to be repaired can be overlapped and repaired as one, thereby completing the repair of the insulation layer of the cable to be repaired. Compared with the prior art, the cable insulation repair device repairs the insulation layer of the cable by hot welding, so as to replace the prior art of using insulating tape to repair the insulation layer of the cable. Since there is no need to use insulating tape, it can avoid the safety hazard of the use of the cable due to the aging of the insulating tape. Moreover, the cable insulation repair device has a simple structure and is easy to operate, which can improve the convenience of repairing the insulation layer and improve the repair efficiency. Furthermore, the cable insulation repair device adopts an external heating method, which can be unaffected by the on-site environment of the cable to be repaired when repairing the cable to be repaired, thereby improving the adaptability of the cable insulation repair to the use environment.

[0034] In some embodiments, in combination Figure 2 and Figure 3 The first support frame 5 includes a hinged first support plate 51 and a second support plate 52. The first support plate 51 and the second support plate 52 are both semicircular. The first support plate 51 and the second support plate 52 are buckled together to form a first cable accommodating cavity.

[0035] In this way, when it is necessary to place the end of the first broken section of the cable to be repaired, the first support plate 51 and the second support plate 52 can be separated first, and then the end of the first broken section can be placed on the first support plate 51, and then the second support plate 52 can be rotated to engage with the first support plate 51 and fixed, so as to lock the end of the first broken section in the first cable accommodating cavity.

[0036] In some embodiments, in combination Figure 4 and Figure 5 The second support frame 6 includes a hinged third support plate 61 and a fourth support plate 62, the third support plate 61 and the fourth support plate 62 are both semicircular, and the third support plate 61 and the fourth support plate 62 are buckled together to form a second cable accommodating cavity.

[0037] In this way, when it is necessary to place the end of the second broken segment of the cable to be repaired, the third support plate 61 and the fourth support plate 62 can be separated first. Then, the end of the second broken segment is placed on the third support plate 61, and the fourth support plate 62 is rotated and buckled on the third support plate 61 and fixed, so as to lock the end of the second broken segment in the second cable accommodating cavity.

[0038] In some embodiments, as Figure 3 shown, a first hinge 10 is provided between the first support plate 51 and the second support plate 52. One end of the first hinge 10 is fixedly connected to the first support plate 51, and the other end is fixedly connected to the second support plate 52.

[0039] As Figure 5 shown, a second hinge 11 is provided between the third support plate 61 and the fourth support plate 62. One end of the second hinge 11 is fixedly connected to the third support plate 61, and the other end is fixedly connected to the fourth support plate 62

[0040] Through the above settings, the mutual hinge between the first support plate 51 and the second support plate 52 can be realized, which facilitates the opening and closing of the first support plate 51 and the second support plate 52, so as to lock the end of the first broken segment in the first cable accommodating cavity; the mutual hinge between the third support plate 61 and the fourth support plate 62 can be realized, which facilitates the opening and closing of the third support plate 61 and the fourth support plate 62, so as to lock the end of the second broken segment in the second cable accommodating cavity.

[0041] In some embodiments, as Figure 3 shown, between the end of the first support plate 51 far from the first hinge 10 and the end of the second support plate 52 far from the first hinge 10, a first fastening device 9 is provided. The first fastening device 9 is used to lock the first support plate 51 and the second support plate 52 to lock the end of the first broken segment of the cable to be repaired.

[0042] Exemplarily, the first fastening device 9 can be an adjusting bolt. Protrusions are provided at both the end of the first support plate 51 far from the first hinge 10 and the end of the second support plate 52 far from the first hinge 10. The adjusting bolt passes through the above two protrusions to realize the locking of the first support plate 51 and the second support plate 52.

[0043] As Figure 5 shown, between the end of the third support plate 61 far from the second hinge 11 and the end of the fourth support plate 62 far from the second hinge 11, a second fastening device 12 is provided. The second fastening device 12 is used to lock the third support plate 61 and the fourth support plate 62 to lock the end of the second broken segment of the cable to be repaired.

[0044] Exemplarily, the second fastening device 12 is an adjusting bolt. Protrusions are provided at one end of the third support plate 61 away from the second hinge 11 and one end of the fourth support plate 62 away from the second hinge 11. The adjusting bolt passes through the two protrusions to lock the third support plate 61 and the fourth support plate 62.

[0045] In some embodiments, in combination Figure 1 with Figure 3 , a first fixing rod 7 is provided at the front end of the first handle 1, and a first fixing sleeve 8 is provided outside the first support frame 5. The first fixing rod 7 extends into the first fixing sleeve 8 to fix the first support frame 5 at the front end of the first handle 1.

[0046] It should be noted that the direction in which the first fixing rod 7 extends into the first fixing sleeve 8 is from the first support frame 5 to the second support frame 6. This can ensure that when the holding portions of the first handle 1 and the second handle 2 are pinched, the first fixing rod 7 is prevented from falling out of the first fixing sleeve 8.

[0047] In combination Figure 1 with Figure 5 , a second fixing rod 13 is provided at the front end of the second handle 2, and a second fixing sleeve 14 is provided outside the second support frame 6. The second fixing rod 13 extends into the second fixing sleeve 14 to fix the second support frame 6 at the front end of the second handle 2.

[0048] It should be noted that the direction in which the second fixing rod 13 extends into the second fixing sleeve 14 is from the second support frame 6 to the first support frame 5. This can ensure that when the holding portions of the first handle 1 and the second handle 2 are pinched, the second fixing rod 13 is prevented from falling out of the second fixing sleeve 14.

[0049] Through the above settings, the difficulty of replacing the first support frame 5 and the second support frame 6 can also be reduced, so that it is convenient to replace the appropriate first support frame 5 and second support frame 6 according to the outer diameter dimensions of different cables to be repaired, and the repair efficiency for different cables to be repaired can be improved.

[0050] In some embodiments, as shown in combination Figure 1 , Figure 3 and Figure 5 , the first fixing sleeve 8 is provided in the middle of the outside of the first support frame 5, and the second fixing sleeve 14 is provided in the middle of the outside of the second support frame 6.

[0051] In this way, when the holding portions of the first handle 1 and the second handle 2 are pinched, the first support frame 5 and the second support frame 6 can be stressed evenly.

[0052] In some embodiments, the material of the first support frame 5 is copper or aluminum, and the material of the second support frame 6 is copper or aluminum.

[0053] Copper and aluminum have relatively low hardness. When repairing the insulating layer, it can not only ensure the normal locking of the cable to be repaired, but also prevent the cable to be repaired from being worn or damaged during the repair of the insulating layer due to the too hard materials of the first support frame 5 and the second support frame 6.

[0054] In some embodiments, as Figure 1 shown, an elastic member 3 is provided between the holding portions of the first handle 1 and the second handle 2, and the elastic member 3 is in a pre-compressed state.

[0055] Exemplarily, the elastic member 3 is a compression spring.

[0056] This can facilitate the mutual separation of the holding portions of the first handle 1 and the second handle 2 by the elastic force of the elastic member 3 after the repair of the insulating layer is completed, so that the first support frame 5 and the second support frame 6 automatically open.

[0057] In some embodiments, rounded chamfers are provided at the edges of the inner wall of the first cable receiving cavity and the edges of the inner wall of the second cable receiving cavity.

[0058] This can avoid damage to the cable to be repaired caused by the edges of the inner wall of the first cable receiving cavity and the edges of the inner wall of the second cable receiving cavity.

[0059] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
