The thermocouple temperature probe can detect the surface temperature of the cable fixed to the mold body.

[0009] The control device is capable of controlling the heating device.

[0010] Preferably, the mold body is provided with fastening bolts at both ends of the edge.

[0011] Preferably, a fixing groove is provided in the middle of the mold body, and a fixing half-groove is provided at the edge of the mold body.

[0012] Preferably, the mold body is fixed by the fastening bolts, and after the mold body is assembled, the fixing half-grooves provided on the edge of the mold body are connected to each other to form a fixing groove.

[0013] Preferably, the thermocouple temperature probe is capable of detecting the temperature of the cable surface, and the thermocouple temperature probe is fixed in the fixing groove.

[0014] Preferably, the heating pack can be installed on the surface of the mold body.

[0015] The beneficial effects of this utility model are:

[0016] (1) Through this utility model, it is found that the sheath layer of a cable is easily damaged during use, and the protective effect of the sheath layer on the cable is weakened after the sheath layer is damaged. By setting a repair mold on the outside of the cable to repair the cable, it can be ensured that the subsequent use of the cable is not affected. The repair mold includes a mold body and a heating device. The mold body can ensure that the outer diameter of the repaired cable is consistent with the outer diameter of the original cable.

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figures 1-3 As shown, a portable, quick-repair tool for cable sheaths includes a repair mold capable of repairing the cable sheath. During the use of cable 2, due to machine laying, the sheath layer of cable 2 is easily scratched by the machine, resulting in some damage. Subsequent use of cable 2 requires repair of the damaged sheath layer before reuse. Traditional repair methods involve heating the cable sheath layer using tools such as hot iron plates or blowtorches, and then repairing the sheath layer with repair materials. This type of repair method results in a significant difference in surface quality between the repaired and undamaged cable 2, easily leading to secondary damage.

[0027] Reference Figure 1 The repair mold includes a mold body 1, a heating device, and a control device. There are two mold bodies 1, and each mold body 1 is arched. When the two mold bodies 1 are combined, they form a hollow cylinder, which can hold the cable 2 that needs to be repaired and the heating device.

[0028] Reference Figures 2-3 The mold body 1 is arched, and a fixing frame for accommodating the fixing device is provided at the edge of the mold body 1. The fixing frame is provided with screw holes 13. In this embodiment, the mold body 1 is fixed by bolts.

[0029] After the two mold bodies 1 are combined, the fastening bolts 3 can be set in the screw holes 13 to fix the mold bodies 1.

[0030] The arched top of the mold body 1 is provided with multiple fixing grooves 11. Each fixing groove 11 is cylindrical, and multiple fixing grooves 11 can be provided on the mold body 1, with equal spacing between them. In this embodiment, there are two fixing grooves, and the spacing between them is equal. A fixing half-groove 12 is provided on the side of the mold body 1. The fixing half-groove 12 is half of the fixing groove 11. After two mold bodies 1 are assembled, the fixing half-grooves 12 on the mold body 1 can connect to each other to form a fixing groove. The position of the fixing half-groove 12 corresponds to the position of the fixing groove 11.

[0031] The diameter of the mold body 1 is the same as the diameter of the cable 2. The mold body 1 is fixed to the cable 2 and secured with screw holes 13 to prevent the mold body 1 from shifting on the cable 2. When the diameter of the cable 2 to be repaired changes, the mold body 1 has multiple sizes. By selecting the appropriate mold body 1 according to the diameter of the cable 2 to be repaired, the repair effect of cables 2 of different sizes can be guaranteed.

[0032] The heating device includes a heating element and a thermocouple temperature probe. (Refer to...) Figure 1 , Figure 3 The heating pack is positioned on the outside of the mold body 1, enclosing it. Inside the heating pack is a heating element that can be connected to a power source to convert electrical energy into heat energy. A thermocouple temperature probe is fixed to the heating pack, specifically in a fixing groove formed by the fixing slot 11 of the mold body 1 and two fixing half-grooves 12 after the two mold bodies 1 are fitted together. The thermocouple temperature probe can detect the current temperature of the cable 2 and convert it into a signal that is transmitted to the control device.

[0033] In this embodiment, the heating pack is strip-shaped and can be arranged around the surface of the mold body 1. The thermocouple temperature probe is arranged on one side of the heating pack. The thermocouple temperature probe can be fixed in the mold body 1 through the fixing groove formed by the combination of the fixing groove 11 and two fixing half grooves 12. The thermocouple temperature probe can detect the temperature of the surface of the cable 2 through the hole.

[0034] In this embodiment, the heating pack includes a shell, a heating device, an energy supply system, and a plastic structure. The energy supply system is connected to the heating device and fixed inside the plastic structure. The shell encloses the plastic structure, and the plastic structure can be adjusted in shape to cover the outside of the mold body 1.

[0035] The plastic structure uses metal heat-conducting sheets, the heating device uses electric heating wire, the power supply system includes a power interface and a battery, and the outer shell is made of silicone.

[0036] The device comprises multiple layers of metal heat-conducting sheets, with heating wires positioned between them. These heating wires connect to a power interface or a battery, which provides power to the heating elements. When an external power source is available at the repair site, the heating element can be powered via the power interface. When no external power source is available, the metal heat-conducting sheets are powered by a battery, making it suitable for work sites without power.

[0037] An outer shell made of silicone is wrapped around the plastic structure. The plastic structure can change its own state and wrap around the outside of the mold body 1. The outer shell can protect the plastic structure during use and prevent it from being damaged and reducing the heating effect.

[0038] The thermocouple temperature probe is set on the side of the heating pack that contacts the mold body 1. The thermocouple temperature probe can detect the temperature of the cable inside the mold body 1.

[0039] The control device can control the heating device, specifically:

[0040] The control device includes a regulator, which allows the operator to set the heating temperature and heating time of the heating pack. The regulator is connected to the heating pack and a thermocouple temperature probe. The thermocouple temperature probe detects the temperature of the cable surface and transmits this temperature reading to the regulator. The regulator adjusts the temperature of the heating pack based on the temperature detected by the thermocouple temperature probe. This ensures that the temperature of the heating pack does not become too high, which could damage the internal structure of cable 2, or that it does not become too low, preventing the repair adhesive strip from repairing the cable properly.

[0041] The working principle of the heating device is as follows:

[0042] 1. Heating:

[0043] After the power is turned on, current flows through the heating wire, and the inductive energy of the heating wire is converted into heat energy. The heat is transferred to the mold body 1 through the heating pack, raising the temperature of the mold.

[0044] 2. Deformation:

[0045] By using a plastic structure, the shape of the heating pack can be fitted to the surface of the mold body 1, preventing uneven heat transfer. When the size of the mold body 1 changes, the fit between the mold body 1 and the heating pack becomes poor.

[0046] 3. Control system:

[0047] The control system transmits signals to the thermocouple temperature probe, and then adjusts the heating element according to the set temperature and time to ensure temperature stability.

[0048] 4. Repair process:

[0049] The mold body 1 uses heat to soften and flow the repaired film, filling the damaged portion of the cable.

[0050] The cable was then cured under temperature control, completing the repair.

[0051] The heating pack, through the aforementioned principles and structure, ensures uniform heat distribution during cable repair, while also being easy to operate and carry.

[0052] How to use a portable tool for quickly repairing cable sheaths:

[0053] 1. Fix the damaged cable 2 and the repair film to the mold body 1. There are two mold bodies 1. The repair film is fixed at the damaged position of the cable sheath.

[0054] 2. Use fastening bolts 3 to fix the two mold bodies 1 to prevent the mold bodies 1 from shifting;

[0055] 3. Install the heating pack and fix it to the surface of the mold body 1;

[0056] 4. When fixing the heating pack, fix the thermocouple temperature probe in the fixing groove formed by the fixing groove 11 and the fixing half groove 12;

[0057] 5. Start the heating pack and set the temperature of the heating pack to 200℃ and the heating time to 20 minutes in the control device;

[0058] 6. After heating is complete, wait for it to cool naturally; after cooling, loosen bolt 3.

[0059] In this invention, electric heating is used, avoiding the use of open flames and high temperatures to heat the cable sheath in traditional cable repair methods, thus reducing safety hazards during the repair process. Repair film is applied to the damaged area of ​​cable 2, and the outer diameter of the repaired cable 2 is controlled by the mold body 1, ensuring that the outer diameter of the repaired cable 2 matches that of the original cable. Furthermore, the heating element transfers heat through the mold body 1, ensuring uniform heating of the cable 2 and high-quality repair. Structurally, this invention features a compact tool that is easy to operate and can repair cable 2 to a high quality under various conditions.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
