Description

Technical Field

[0001] The present application relates to the field of cables, and in particular to a pressure-resistant and wear-resistant cable and a production process thereof. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of wires. During and after the cable is laid, it may be stepped on or worn.

[0003] The cables in the related art are merely wrapped with a thicker armor on the outside.

[0004] When the cable is stepped on or impacted, the outside of the cable directly bears the pressure and impact force. Without any buffer, the speed at which the outside of the cable is damaged will be accelerated, and even the use of the entire cable will be affected. Summary of the invention

[0005] In order to solve the problem of no external buffering when the cable is under pressure or impact, the present application provides a pressure-resistant and wear-resistant cable and a production process thereof.

[0006] The present application provides a pressure-resistant and wear-resistant cable and a production process thereof, which adopts the following technical solutions:

[0007] In a first aspect, the present application provides a pressure-resistant and wear-resistant cable, which adopts the following technical solution:

[0008] A pressure-resistant and wear-resistant cable comprises a cable portion; a protective portion, the protective portion being wrapped and fixed outside the cable portion; a buffer portion, the buffer portion being provided with at least one, the buffer portion being sleeved outside the protective portion, a space being provided between the protective portion and the buffer portion, the buffer portion being fixed to the protective portion, a plurality of slits being provided on an inner wall of the buffer portion, the slits being distributed along the circumference of the buffer portion, and the length direction of the slits being consistent with the length direction of the buffer portion.

[0009] By adopting the above technical solution, the protective part outside the cable part plays a protective role on the cable part. When using the present application, it is necessary to first determine whether the cable is locally compressed or overall compressed. If it is only locally compressed, the buffer part is sheathed outside the part that may be compressed or impacted, and then the buffer part and the protective part are fixed. If the entire cable is compressed, the buffer part is sheathed outside the entire cable. When pressure and impact force act on the buffer part, the distance between the buffer part and the protective part plays a buffering role, reducing the possibility of pressure and impact force acting directly on the cable part. The problem of no external buffer when the cable is under pressure or impact is solved; at the same time, since the inner wall of the buffer part is provided with a slit, when the buffer part is locally stressed, the existence of the slit makes the local wall thickness of the buffer part thinner, and only the stressed part is concave inward, which will not cause a significant impact on the entire buffer part; at the same time, since the protective part and the buffer part are both rubber, when the outside of the buffer part is stepped on, a certain degree of relative movement will occur between the protective part and the buffer part, thereby offsetting the stepping pressure and reducing the wear of the protective part. The existence of the protective part and the buffer part can also protect the cable and resist wear and corrosion.

[0010] Optionally, a plurality of ribs are provided outside the protective portion, the length direction of the ribs is consistent with the length direction of the protective portion, the plurality of ribs are distributed along the circumference of the protective portion, there is a space between two adjacent ribs, and there is a space between one end of the rib away from the protective portion and the inner wall of the buffer portion.

[0011] By adopting the above technical solution, in actual use, the existing cables will bend in many places, affecting the laying and use. The cable part with the added ribs is straighter, reducing the possibility of the cable bending. At the same time, the ribs also play a certain degree of buffering, pressure resistance and wear resistance, and play a better protective role in the position where the buffer part is not set on the cable part.

[0012] Optionally, the rib includes an inclined surface, which extends along the length direction of the rib and is inclined toward the inner side of the rib in a direction away from the cable portion. The inner wall of the buffer portion is provided with a plurality of push bars, which are distributed circumferentially along the buffer portion. The push bars extend along the length direction of the buffer portion, one push bar is inserted between two adjacent ribs, one push bar is abutted against one of the inclined surfaces, and there is a space between one end of the push bar close to the protective portion and the protective portion.

[0013] By adopting the above technical solution, when the protective part is locally sunken due to pressure, the inclined surface acts as abutment against the resistance bar, allowing the resistance bar to move downward while avoiding excessive downward movement of the resistance bar, reducing the degree of sinking of the protective part at the stress-bearing part, and avoiding a large degree of deformation of the protective part as a whole.

[0014] Optionally, one edge strip is inserted between two adjacent support strips.

[0015] By adopting the above technical solution, when the protective part is subjected to greater force and sinks to a greater extent, the ribs support the protective part, and a rib is inserted between two adjacent support bars to support all thin-wall positions as much as possible, so that the protective part can be better supported when subjected to force and will not sink significantly.

[0016] Optionally, two adjacent resistance bars are arranged at intervals.

[0017] By adopting the above technical solution, the spaced-apart stays provide an insertion space for the ribs, thereby preventing the two stays from being damaged to an irreversible state when the ribs are inserted between the two stays.

[0018] Optionally, a plurality of the ribs outside the protective portion form an external tooth structure, and the inclined surface is located on one side of the length direction of the ribs.

[0019] By adopting the above technical solution, in order to facilitate production and processing, an optimal solution for the edge strips of the present application is provided, which is easy to groove and process.

[0020] Optionally, a plurality of the support bars in the buffer portion form an inner tooth structure, and the side walls on both sides along the length direction of the support bars cut into the inner wall of the buffer portion to form the slits.

[0021] By adopting the above technical solution, in order to facilitate production and processing, an optimal solution for the strips and slits of the present application is provided, which is easy to process and produce.

[0022] Optionally, it further includes a plurality of fixing rings, wherein the fixing rings are sleeved outside the protective part, and the protective part and the buffer part are fixed by the fixing rings.

[0023] By adopting the above technical solution, when the buffer part needs to be fixed outside the protective part, the fixing ring is first put on the outside of the protective part for fixing, and then the buffer part is fixed on the fixing ring. The position of the fixing ring can be adjusted and fixed according to the position of the buffer part to be installed.

[0024] In a second aspect, the present application provides a production process for a pressure-resistant and wear-resistant cable, which adopts the following technical solution:

[0025] A production process for a pressure-resistant and wear-resistant cable, the steps are as follows:

[0026] Wrap the cable portion with a rubber sleeve, and open a plurality of long grooves at intervals along the circumferential direction on the outer wall of the rubber sleeve to form the protective portion and the ribs; take an annular rubber sleeve, and open a plurality of long grooves at intervals along the circumferential direction on the inner wall of the annular rubber sleeve to form the buffer portion and the support strip, and open the slit on the inner wall of the buffer portion; sleeve the buffer portion on the cable portion to be protected; ensure that the support strip abuts against the inclined surface, ensure that there is a space between the support strip and the protective portion, ensure that there is a space between the ribs and the buffer portion, and then fix the buffer portion and the protective portion to each other.

[0027] By adopting the above technical solution, a protective part with ribs and a buffer part with abutment bars are processed and formed, and after installation and fixation, the pressure-resistant and wear-resistant cable structure of the present application can be formed.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The protection part and the buffer part cooperate with each other to solve the problem of no external buffer when the cable is under pressure or impact;

[0030] 2. The slits make the depression area of ​​the buffer part where pressure is applied smaller;

[0031] 3. The abutment between the abutment strip and the inclined surface reduces the degree of sinking of the buffer part when it is subjected to force, and controls the deformation of the buffer part. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The embodiment of the present application discloses a pressure-resistant and wear-resistant cable.

[0039] Reference Figure 1A pressure-resistant and wear-resistant cable includes a cable portion 1, a protective portion 2, a buffer portion 3 and a fixing ring 4.

[0040] Reference Figure 1 and Figure 2 The cable portion 1 is a wrapped cable; the rubber protective portion 2 is wrapped and fixed outside the cable portion 1, and a plurality of ribs 21 are integrally connected to the outside of the protective portion 2. The length direction of the ribs 21 is consistent with the length direction of the protective portion 2. The plurality of ribs 21 are evenly distributed along the circumference of the protective portion 2, and there is a space between two adjacent ribs 21. The plurality of ribs 21 outside the protective portion 2 form a trapezoidal external tooth structure; the rib 21 includes an inclined surface 211, which extends along the length direction of the rib 21, and the inclined surface 211 is inclined toward the inner side of the rib 21 in the direction away from the cable portion 1, and the inclined surface 211 is located on one side of the length direction of the rib 21.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The buffer part 3 is made of rubber and is provided with at least one. The number of buffer parts 3 is determined by the number of cable part 1 positions that need to be protected. The buffer part 3 is sleeved outside the protective part 2. There is a gap between the protective part 2 and the buffer part 3. There is a gap between the end of the rib 21 away from the protective part 2 and the inner wall of the buffer part 3. The inner wall of the buffer part 3 is provided with a plurality of slits 31, which are distributed along the circumference of the buffer part 3, and the length direction of the slits 31 is consistent with the length direction of the buffer part 3. The inner wall of the buffer part 3 is integrally connected with a plurality of ribs 32, which are evenly distributed along the circumference of the buffer part 3, and adjacent ribs 32 are uniformly distributed along the circumference of the buffer part 3. Two push bars 32 are arranged at intervals, and the push bars 32 extend along the length direction of the buffer part 3. One push bar 32 is inserted between two adjacent ribs 21, and one rib 21 is inserted between two adjacent push bars 32. There is a space between the end of the push bar 32 close to the cable part 1 and the protective part 2; a plurality of push bars 32 in the buffer part 3 form a triangular internal tooth structure, and the side walls on both sides of the length direction of the push bars 32 are cut into the inner wall of the buffer part 3 to form a slit 31, and one push bar 32 is in contact with an inclined surface 211, and the side wall on one side of the length direction of the push bar 32 is in contact with the inclined surface 211 of the rib 21.

[0042] Reference Figure 3 and Figure 4 The number of fixing rings 4 is twice the number of buffer parts 3. The fixing rings 4 are sleeved on the outside of the protective part 2. The inner wall of the fixing ring 4 is bonded and fixed to the rib 21 outside the protective part 2. A buffer part 3 is fixed between the two fixing rings 4. Both ends of the buffer part 3 are bonded and fixed to the fixing rings 4. The protective part 2 and the buffer part 3 are fixed by the fixing rings 4. When the protective part 2 and the buffer part 3 are fixed, it is ensured that an abutment bar 32 abuts against an inclined surface 211. At this time, the side wall on one side of the length direction of the abutment bar 32 contacts and abuts against the inclined surface 211 of the rib 21.

[0043] The implementation principle of a pressure-resistant and wear-resistant cable in an embodiment of the present application is as follows: when the protective part 2 is locally subjected to force, the existence of the slit 31 causes the protective part 2 to sink only locally, and the abutment between the ribs 21 and the abutment bars 32 limits the degree of sinking of the protective part 2; when the protective part 2 is subjected to oblique pressure, a relative displacement will occur between the protective part 2 and the buffer part 3, thereby offsetting the force on the protective part 2 and reducing the possibility of wear of the protective part 2.

[0044] The embodiment of the present application also discloses a production process of a pressure-resistant and wear-resistant cable.

[0045] A production process for a pressure-resistant and wear-resistant cable, the steps are as follows:

[0046] The cable portion 1 is wrapped with a rubber sleeve, and a plurality of long grooves are evenly spaced along the circumferential direction on the outer wall of the rubber sleeve to form a protective portion 2 and ribs 21 .

[0047] Take an annular rubber sleeve, and open a plurality of long grooves evenly spaced along the circumferential direction on the inner wall of the annular rubber sleeve to form a buffer portion 3 and a stop strip 32 , and open a slit 31 on the inner wall of the buffer portion 3 .

[0048] Sleeve the buffer part 3 and the fixing ring 4 over the cable part 1 to be protected, ensure that the abutment bar 32 abuts against the inclined surface 211, and at the same time, ensure that there is a space between the buffer part 3 and the protective part 2, ensure that there is a space between the abutment bar 32 and the protective part 2, ensure that there is a space between the rib 21 and the buffer part 3, and then fix the buffer part 3 and the protective part 2 by the fixing ring 4.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
