Description

Technical Field

[0001] The utility model belongs to the technical field of cable body production, and particularly relates to an armored cable. Background Art

[0002] Armoring refers to the outermost layer of metal, such as hot-dip galvanized steel wire, applied to cables that must withstand significant mechanical forces to prevent damage to the inner layer during transportation and installation. The steel wire used in armored cables is widely used in submarine and underground cables for communications, automation, and power generation.

[0003] After searching, Chinese patent authorization announcement number CN219832212U discloses an armored cable, including four trapezoidal cables and one round cable, the four trapezoidal cables are located around one round cable, and the side walls of two adjacent trapezoidal cables are in conflict with each other, and the side of the four trapezoidal cables close to the round cable is constructed into an arc that fits the outer wall of the round cable. This application sets four trapezoidal cables and one round cable, and the four trapezoidal cables contact the outer wall of the round cable and the inner wall of the armored protective layer through the arc-shaped outer walls on both sides, so that the four trapezoidal cables wrap around the round cable, and at the same time, the armored protective layer wraps around the four trapezoidal cables. This design can make the cables tightly combined together, thereby minimizing the use of fillers in the cable while ensuring the normal use of the armored cable, thereby reducing the production cost of the cable.

[0004] However, when the above-mentioned device is installed in a location with relatively high strength, such as the lower end of a road or other locations, the armor of the cable body itself cannot block the strong external force. Long-term use can easily cause the cable body to be damaged, affecting normal use. Therefore, it is necessary to provide an armored cable that can protect the outer wall of the cable body installed in a location with relatively high strength.

[0005] Practical content

[0006] This utility model aims at solving the problem that when the above-mentioned device is installed in a location with high strength, such as the lower end of the road or other locations, the armor of the cable body itself cannot block the strong external force. Long-term use may easily damage the cable body, affecting normal use. The following technical solutions are proposed:

[0007] Cable body;

[0008] The protective mechanism includes a hard protective cover that is slidably sleeved on the circumferential outer wall of the cable body, a metal fixing sleeve is fixedly connected to the middle outer wall of the hard protective cover, two rotating frames are symmetrically threadedly connected to the outer wall of the metal fixing sleeve, metal tightening frames are fixedly connected to the outer walls of both ends of the metal fixing sleeve at equal distances around the circumference, and a fixing frame is fixedly connected to the inner wall of the metal tightening frame.

[0009] As a preferred embodiment of the above technical solution, the hard protective cover is sleeved on the outer wall of the cable body at a position where the external force intensity is greater, and the metal tightening frame is elastic.

[0010] As a preferred embodiment of the above technical solution, the outer diameter of the metal tightening frame in a natural state is larger than the inner diameter of the rotating frame, and the inner diameter of the fixing frame on the inner wall of the metal tightening frame in a contracted state is smaller than the outer wall of the hard protective cover.

[0011] As a preferred embodiment of the above technical solution, a supporting mechanism is further included, wherein the supporting mechanism includes a supporting frame fixedly connected to the circumferential outer wall of the cable body at equal intervals, and a telescopic hole is opened in the inner cavity of the supporting frame.

[0012] As a preferred embodiment of the above technical solution, the inner wall of the telescopic hole is slidably connected to a telescopic rod, the outer wall of the telescopic rod is equidistantly provided with limiting holes, and the outer wall of the support frame is threadedly connected to a limiting rod corresponding to the limiting hole.

[0013] As a preferred embodiment of the above technical solution, a base is fixedly connected to the outer wall of the bottom of the telescopic rod, and a limiting axis is fixedly connected between the support frames located at both ends of the bending part of the cable body.

[0014] The beneficial effects of this utility model are:

[0015] The utility model slides the hard protective cover to the position where the cable body is located at a greater strength, manually rotates the rotating frame, and makes the two rotating frames move in opposite directions along the metal fixing sleeve. When the rotating frame moves to contact the metal tightening frame, the rotating frame is continued to rotate to move the rotating frame toward the end of the hard protective cover, and the metal tightening frame is pushed by the rotating frame to cause the metal tightening frame to contract centripetally. The metal tightening frame drives the fixing frame to fix the hard protective cover to the outer wall of the cable body. The outer wall of the cable body at a greater strength position can be protected by the hard protective cover, and the hard protective cover can be fixed.

[0016] The utility model discloses that when the cable body is placed on the cable bracket, the base contacts the outer wall of the cable bracket, and the cable body is supported by the base, the telescopic rod and the support frame. After adjusting the length of the telescopic rod in the support frame, the limit rod is installed in the limit hole to limit the telescopic rod. This can avoid direct contact and friction between the cable body and the cable bracket, extend the service life of the cable body, adjust the distance between the cable body and the cable bracket, and facilitate the maintenance of the cable body by the staff.

[0021] In order to make the purpose, technical solution and advantages of this practical embodiment clearer, the practical technical solution will be clearly and completely described below in conjunction with the embodiments.

[0022] See also Figure 1-3 As shown, this embodiment is an armored cable, comprising:

[0023] Cable body 1;

[0024] The protective mechanism 2 includes a hard protective cover 201 that is slidably sleeved on the outer wall of the cable body 1. A metal fixing sleeve 202 is fixedly connected to the middle outer wall of the hard protective cover 201. Two rotating frames 204 are symmetrically threadedly connected to the outer wall of the metal fixing sleeve 202. Three metal tightening frames 203 are fixedly connected to the outer walls of the two ends of the metal fixing sleeve 202 at equal intervals around the circumference. The outer walls of the metal tightening frames 203 are threadedly connected to the inner walls of the rotating frames 204. The ends of the inner walls of the metal tightening frames 203 are fixedly connected to the fixed frames.

[0025] The cable body 1 is protected by the hard protective cover 201, and the metal tightening frame 203 and the rotating frame 204 are supported by the metal fixing sleeve 202. The metal tightening frame 203 is retracted by the rotating frame 204, and the metal tightening frame 203 drives the fixing frame to fix the hard protective cover 201;

[0026] The hard protective cover 201 is sleeved on the outer wall of the cable body 1 at a position with greater external force intensity, and the metal tightening frame 203 is elastic;

[0027] The outer diameter of the metal tightening frame 203 in its natural state is larger than the inner diameter of the rotating frame 204 , and the inner diameter of the fixing frame on the inner wall of the metal tightening frame 203 in its contracted state is smaller than the outer wall of the hard protective cover 201 .

[0028] Working principle:

[0029] Slide the hard protective cover 201 to a position where the cable body 1 is at greater strength, manually rotate the rotating frame 204 to make the two rotating frames 204 move in opposite directions along the metal fixing sleeve 202. When the rotating frame 204 moves to contact the metal tightening frame 203, continue to rotate the rotating frame 204 to move the rotating frame 204 toward the end of the hard protective cover 201. The rotating frame 204 pushes the metal tightening frame 203 to cause the metal tightening frame 203 to contract centripetally. The metal tightening frame 203 drives the fixing frame to fix the hard protective cover 201 to the outer wall of the cable body 1.

[0030] In this step, the outer wall of the cable body 1 at a position with greater strength can be protected by the hard protective cover 201 , and the hard protective cover 201 can be fixed.

[0031] See also Figure 1-3 As shown, this embodiment is based on the above embodiment and also includes

[0032] The support mechanism 3 includes a support frame 301 fixedly connected to the outer wall of the cable body 1 at equal intervals, and a telescopic hole is opened in the inner cavity of the support frame 301;

[0033] Extend the moving range of the telescopic rod 302 through the support frame 301;

[0034] The inner wall of the telescopic hole is slidably connected to a telescopic rod 302, and the outer wall of the telescopic rod 302 is equidistantly provided with limit holes 303, and the outer wall of the support frame 301 is threadedly connected to a limit rod 304 corresponding to the limit holes 303;

[0035] The length of the telescopic rod 302 is adjusted and limited by the limiting rod 304 installed in the limiting hole 303;

[0036] The bottom outer wall of the telescopic rod 302 is fixedly connected to a base 305, and a limit axis 306 is fixedly connected between the support frames 301 at both ends of the bend of the cable body 1;

[0037] The support frame 301 is supported by the base 305 and the fixed telescopic rod 302, the cable body 1 is supported by the support frame 301, and the bending part of the cable body 1 is limited by the limiting shaft 306;

[0038] Working principle:

[0039] When the cable body 1 is placed on the cable bracket, the base 305 contacts the outer wall of the cable bracket, and the cable body 1 is supported by the base 305, the telescopic rod 302 and the support frame 301. After adjusting the length of the telescopic rod 302 in the support frame 301, the limiting rod 304 is installed in the limiting hole 303 to limit the telescopic rod 302. The limiting shaft 306 limits the bending part of the cable body 1 to prevent the cable body 1 from being excessively bent.

[0040] This step can avoid direct contact and friction between the cable body 1 and the cable bracket, extend the service life of the cable body 1, adjust the distance between the cable body 1 and the cable bracket, and facilitate staff to inspect and repair the cable body 1.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, rather than to limit it.
